A hydraulic tool for assembling and disassembling components, such as gear, bearing and etc, of a shaft, is capable of performing external-pulling or internal pulling operation as desired for an object to be assembled or disassembled. The hydraulic tool comprises an oil pressure assembly consisted of a hand-operated pump, an oil storage member, a control valve, an oil pressure tank, a set of external pulling type clamping jaws, internal pulling type clamping jaws, and a bolt for assembling purpose. The hydraulic tool has high mobility, portability and is capable of perforation assembling or disassembling operation at any angle and position, and is considerably enhanced in applicability.

The invention discloses a laser navigation AGV high-precision positioning and target alignment control method, and relates to the technical field of mobile robot navigation. Point cloud segmentation and extraction is performed on the target environment features based on the laser point cloud to realize the capability of the AGV to acquire the target feature point cloud in real time; based on a nearest neighbor method, the problems of finding corresponding points in point cloud matching and establishing a target function are solved; a multi-resolution search matching method based on gradient point cloud density is designed, and branch and bound optimization search is carried out. High-precision and low-delay matching of the AGV for the target feature point cloud is realized, and the problemof high-precision positioning of the laser navigation AGV at a specific task point is solved; based on an AGV smooth motion controller, the capability of AGV smooth and accurate motion control to reach a target point is realized. The problems of laser navigation AGV high-precision positioning, pose alignment, charging butt joint and other target alignment control are solved, and the defects thatthe positioning precision of the SLAM technology is insufficient, and a traditional alignment control method is too high in cost are overcome.

The invention provides a rotor, a motor, a reinforcing ring tooling and a mounting method thereof. The reinforcing ring tooling can be mounted at the periphery of the rotor of the motor, the reinforcing ring tooling comprises more than two split components and more than two connecting parts, wherein more than two connecting parts are corresponding to more than two split components, and more than two split components are mutually connected through more than two connecting parts to form an annular body; at least two connecting parts in more than two connecting parts are movable connection parts,and the corresponding split components are mutually and movably connected through the movable connection parts, thereby enabling the reinforcing ring tooling to detachably connect with the peripheryof the rotor. Therefore, one or more aims of preventing the rotor from deforming in the transportation mounting process of the motor, reducing the manufacturing cost of the motor, reducing the transportation and mounting of the motor and like operation difficulties can be realized.

The invention discloses a cutting board and kitchen knife combined device for a kitchen. The cutting board and kitchen knife combined device comprises a water collecting tank and a limiting device, wherein the lower part of the water collecting tank is provided with suckers; a connecting block mounted on one side of a cutting board sleeve is connected with a connecting piece through an extension shaft; the extension shaft is provided with a bolt sleeve; the front surface of the cutting board sleeve is provided with water drain holes; the left and right sides of the interior of the water collecting tank are symmetrically provided with connecting plates; the left and right sides of the cutting board sleeve are provided with through holes in a reservation manner; the limiting device is mutually connected with a connecting shaft; further, the left and right ends of the connecting shaft are mounted on the connecting block through the extension shaft; the bottom of the water collecting tankis provided with bottom tanks. The cutting board and kitchen knife combined device for the kitchen can be used for achieving the purpose of collecting vegetable and fruit juice through the setting ofthe water collecting tank, and is used for avoiding the condition that water flows to a placement plane and cleaning is inconvenient to perform; meanwhile, the cutting board sleeve can be connected with the connecting piece through the connecting shaft; thus, a kitchen knife can be connected onto the cutting board sleeve, and kitchen knife blades can be stored when not in use.

The invention provides a riverbed sediment monitoring sampler, which is mounted in a sampling vehicle body, and comprises a spiral sampling rod for drilling a sediment layer, a mud scraping assembly matched with the spiral sampling rod for use, and a driving assembly for driving the spiral sampling rod to rotationally drill into the sediment layer or spirally withdraw out of the sediment layer; and the mud scraping assembly comprises a bearing plate mounted in the sampling vehicle body and an elastic mud scraping plate fixed on the bearing plate, the free end of the elastic mud scraping plate extends into a spiral groove in the spiral sampling rod, and a plurality of clamping grooves for embedding silt are formed in the spiral groove at intervals. The problems that according to an existing sediment sampler, sediment is inconvenient to unload, and the unloading time is long are solved, the purpose that the sticky sediment in the spiral inter-groove is easily scraped off and falls onto the material receiving plate is achieved, and the sediment sampling efficiency is improved.

The invention discloses an emulsifying method for a sizing agent, and relates to the technical field of papermaking. The method comprises the following steps: preparing raw starch size; adding alkaliliquor and a cationic etherifying agent into the raw starch size, and carrying out an etherification reaction so as to obtain cationic starch size; stewing the cationic starch size so as to gelatinizecationic starch; and adding the gelatinized cationic starch into a sizing agent solution so as to emulsify the sizing agent. Thus, the emulsifying method provided by the invention can reduce the costof an emulsifying process, and improves the applicability of the emulsifying process.
