By designing a folding type automatic driving small vehicle, when not in use, the small vehicle can be automatically folded and deformed and therefore is convenient to carry and place, and when in use, the small vehicle is deformed and stretched and can be automatically driven; the universal folding type automatic driving small vehicle is particularly suitable for transporting and carrying plate type parts and can be used for transporting plates and transporting military supplies.

The invention relates to a material conveying device for construction. The material conveying device at least comprises a first horizontal conveying part arranged in a tunnel, a vertical lifting partarranged in a vertical shaft and a second horizontal conveying part arranged on the ground surface. The first horizontal conveying part is arranged at the intersection of the tunnel and the vertical shaft. The vertical lifting part can convey ballast soil from the first horizontal conveying part to the second horizontal conveying part in a redirection conveying mode. The first horizontal conveyingpart is arranged at the intersection of the tunnel and the vertical shaft, and the position of the first horizontal conveying part is kept unchanged. When the length of an extending conveying part needs to be increased, only construction operation needs to be conducted at the bottom of the vertical shaft, the transportation cost of operation tools and materials is low, and due to the fact that the operation area of an excavating device is far away from the vertical shaft, operation of the excavating device is not affected, and the tunneling speed of the tunnel can be effectively guaranteed.

An electric stapler is operated by the steps of: a paper bundle pinching step of relatively moving a table part and a driver unit and also pinching a paper bundle; a staple separation step of folding a staple into U-shape by a forming plate and also separating the folded U-shape staple from a staple sheet by moving a driver; a penetration step of penetrating legs of the staple into the paper bundle by further moving the driver; a clinch step of inward folding the legs penetrating through the paper bundle by a clinch device; and a paper bundle releasing step of releasing the paper bundle. A relative movement of the table part and the driver unit, the forming plate, the driver, and the clinch device are powered by a single motor. A driving speed of the motor in the steps excluding the penetration step and the clinch step is slower than the driving speed of the motor in the penetration step and the clinch step.

The present invention relates to a method and device for vertical lifting of muck, which at least includes a first horizontal conveying part and an excavating device arranged in a tunnel, a vertical lifting part arranged in a vertical shaft and a second horizontal conveying part arranged on the ground surface. The vertical lifting part can transfer the muck from the first horizontal conveying part to the second horizontal conveying part in the way of diverting transportation, and at least an extended conveying part configured to move toward the excavating device when the straight-line distance between the excavating device and the extending conveying part is greater than a first set threshold; The straight-line distance is smaller than the first set threshold, and muck can be temporarily stored in the extended conveying portion so that the excavating device can continue to perform excavation operations.

The invention discloses a mini folding bicycle, which comprises a vehicle body, a rear fork, a seat, a front fork, V-shaped folding handles, a front wheel, a rear wheel and a driving mechanism, and is characterized in that: the vehicle body comprises a beam tube, a front end tube, a five-way tube and a seat tube; the front end of the beam tube is connected with the front end tube; the bottom of the front end tube is connected with the five-way tube; the rear end of beam tube is connected with the seat tube; the back of the seat tube is connected with the rear fork; the V-shaped folding handles consist of handle base, left and right shafts, left and right handles, left and right quick releases, backing pieces, safety catches and internal expansion tubes; the driving mechanism consists of acentral shaft, a secondary shaft, two cranks, two pedals, a primary chain wheel, a primary minor sprocket, a secondary chain wheel, a primary chain, a rear chain and a flywheel; a front frame is connected with a front part of the folding base; the front fork is connected with the head tube of the vehicle body in a rotary manner; the V-shaped folding handles are connected with the front fork; the front wheel is arranged on the front fork; and the rear wheel is arranged on the rear fork.

The invention discloses an online detection device for abrasion to a disc cutter of a hard rock tunnel boring machine. The online detection device comprises a cutter shaft, a cutter ring, a thickness detection sensor, a signal processing integrator, a support frame, a signal output device, a wireless transmitting device and a wireless receiving device. The thickness detection sensor, the signal processing integrator, the support frame and the signal output device are sequentially arranged in the cutter ring and a cutter body from outside to inside in the radial direction. The signal output device is composed of an electric brush and a slide groove, wherein the slide groove is composed of three sections of contact arcs and three sections of connecting arcs, the central angle of each contact arc is 100 degrees, and the central angle of each connecting arc is 20 degrees. One end of a data line groove in the cutter shaft leads to the slide groove, and the other end of the data line groove in the cutter shaft leads to the portion, outside an end face of the cutter shaft, of the wireless transmitting device. The wireless transmitting device is arranged on a cutter head, the wireless receiving device is arranged on a front shield of the tunnel boring machine, and the wireless receiving device is connected to a TBM main control room through a data line. The online detection device can detect the abrasion to the disc cutter on line and can also judge whether plane abrasion occurs to a working tool or not, and the downtime can be shortened.

The invention discloses a structure-variable safety boat which comprises a river boat body, a sea boat bottom and an auxiliary cabin part. The river boat body comprises a bow structure and a cabin structure; the bow structure is arranged into a round tip structure and is arranged at the head of the cabin structure, and the bow structure and the cabin structure are integrally formed; the cabin structure comprises a cabin tank, a deck and a concave bottom, the deck is arranged at the upper end of the cabin tank and is airtightly and fixedly connected with the cabin tank, and the concave bottom is arranged at the bottom of the cabin tank. The structure-variable safety boat effectively solves the problem that a river boat cannot go to the sea and a sea boat cannot go ashore; by changing the weight of the boat body, controlling the center of gravity and setting the contact area between the boat body and the water surface, real-time control over the stability of the boat body is realized inmultiple dimensions, and auxiliary stabilization of the cabin and emergency escape are also realized.

The invention relates to a gear limiting method applied to heavy AMT vehicles. The method is characterized by comprising the following steps: (1), receiving gear limiting CAN bus information data and reading a limited gear value; (2) determining whether a current vehicle gear is greater than or equal to a gear value which is lower than the limited gear by three gears, turning to the step (3) if yes, or turning to the step (1); and (3) sending limited gear control information TC1 via the vehicle and sending information of an A / M mode and a P / E mode according to the received information, wherein the sent gear is a received gear value.
