The invention discloses a street lamp fast to maintain. The street lamp comprises a lamp holder, and a lamp pole is arranged on the lamp holder. The street lamp is characterized in that a rotary shaft is inserted into one side of the upper end of the lamp pole, a fixing rod is connected to the rotary shaft, a lamp body is inserted into the fixing rod, a drive mechanism capable of driving the lamp body to move relative to the fixing rod is arranged on the lamp holder, a regulating mechanism capable of driving the rotary shaft to rotate so as to regulate the angle is arranged on one side of the lamp pole, and a positioning mechanism capable of positioning the fixing rod is arranged in the position, at the lower end of the fixing rod, of the lamp pole; by inserting the lamp body into the fixing rod, the lamp body can move relative to the fixing rod; the lamp body is driven to move through the drive mechanism, and the lamp body can be placed onto the lamp holder through the drive mechanism during maintenance or replacement; and meanwhile, the angle of the fixing rod is regulated through the regulating mechanism, the drive mechanism drives the lamp body to drop conveniently, the angle of the fixing rod can be locked through the positioning mechanism, free gliding is prevented, and the structure is simple.

The invention discloses a double-brake back-and-forth controllable descent control device. The double-brake back-and-forth controllable descent control device comprises an outer shell, a pulling mechanism, a double-brake mechanism and a rope guiding mechanism, wherein the pulling mechanism, the double-brake mechanism and the rope guiding mechanism are arranged in the outer shell; the pulling mechanism is mutually linked with the double-brake mechanism and comprises an energy conversion regulating screw rod and a buffer piece which is arranged at the periphery of the pulling mechanism; the double-brake mechanism comprises an outer brake assembly, an inner brake assembly and a self locking mechanism, the inner brake assembly is mutually linked with the energy conversion regulating screw rod of the pulling mechanism, a wedge wheel is arranged at the periphery of the inner brake assembly, a steel wire rope is wound on the wedge wheel and is in rolling friction, and the self locking mechanism is movably arranged between the outer brake assembly and the outer shell in a leaning way; when the outer brake assembly is in an unstressed state or a maximum stress state, the inner brake assembly is in a semi-brake state to generate friction damping, and the steel wire rope wound on the peripheral wedge wheel can be tensioned and locked; when the outer brake assembly is in a semi-clutch state, the inner brake assembly and a brake hub are in a friction state by the locking of the inner brake assembly on the steel wire rope, the steel wire rope is enabled to be guided out along the rope guiding mechanism by friction force difference, and slow and uniform-speed descending can be realized.

A double-brake back-and-forth controllable descent device, including an outer shell and a lifting mechanism built in it, a double braking mechanism and a guide rope mechanism, the lifting mechanism and the double braking mechanism are linked to each other, and the lifting mechanism includes energy Convert the adjustment screw and set the outer peripheral buffer. The double brake mechanism includes an outer brake assembly, an inner brake assembly and a self-locking mechanism. The inner brake assembly is linked with the energy conversion adjustment screw of the lifting mechanism. The inner brake assembly There is a wedge wheel on the outer periphery, and a steel wire rope is wound on it for rolling friction. The self-locking mechanism can be movably resisted between the outer brake assembly and the housing. The brake assembly is in the semi-braking state to produce frictional damping, and the wire rope wrapped around the outer peripheral wedge wheel is tightened and locked. When the outer brake assembly is in the half-clutch state, the inner brake assembly locks the wire rope and the brake hub. In the state of friction, the friction force is poor so that the steel wire rope can be drawn out along the guide rope mechanism to achieve slow and uniform descent.

In particular, the invention relates to a turnover device. The technical problem existing when a push rod device is adopted to drive an overturning device to overturn for 180 degrees at present is solved. The turnover device comprises a fixed body and a turnover body. The turnover body can be turned over relative to the fixed body. The turnover device also comprises a push rod device. The push roddevice comprises a telescopic rod capable of stretching and retracting freely. One end of the push rod device is hinged with a stress point on the fixed body. The push rod device can rotate around astress point on the fixed body. The turnover device is characterized in that the other end of the push rod device is connected with the stress point on the turnover body through a stress point offsetdevice; and the stress point offset device is a device capable of enabling the stress point on the turnover body to be skew towards one side of the turnover direction relative to the axis of the telescopic rod in the turnover process of the turnover body. By means of the turnover device, the push rod device can automatically turn over the turnover body for 180 degrees, manual participation is notrequired in the turnover process, and the automation level of the turnover device is greatly improved.

The invention relates to the technical field of textile production equipment, in particular to a glove receiving, placing and finishing device. The technical problem to be solved is to overcome the defects of low collection and finishing efficiency and inability to monitor and count in the prior art, which is mainly achieved through the following technical solutions A kind of glove receiving and finishing device, including: a material receiving device, a transmission device and a packaging device, the material receiving device includes a receiving part, a rotating part, an abutting part and a driving part, the rotating part drives the receiving part to rotate, and the driving part drives the abutting part. The glove is connected to make the gloves fit the receiving part. The transmission device is horizontally arranged at one end of the receiving device to transmit and count the finished gloves. The packaging device receives the gloves conveyed by the transmission device and stacks them neatly. Mutual control, operating different structures to realize the automatic sorting and collection of receipts, reducing the degree of manual dependence and monitoring and counting the quality of finished products, improving the automation of the collection and sorting of gloves.
