The invention provides lifting and transferring equipment for electromechanical equipment assembly, and relates to the technical field of electromechanical equipment assembly. The transfer base is of a rectangular frame structure formed by welding square pipes, and the back of the transfer base horizontally extends to be connected with a horizontal balance weight back seat. A lifting vertical frame is fixedly welded to the connecting position of the transfer base and the balance weight back seat in a vertically upward mode. A lifting air cylinder is fixedly installed at the position, close to the front portion, of the middle of the balance weight back base in a vertically-upward mode. Through the innovative design of the loading slope block, the electromechanical equipment can conveniently slide to the top of the transfer base along the inclined plane of the loading slope block, and through the ingenious connection between the L-shaped clamping table and the transfer base as well as the thrust action of the spring, it is ensured that a gap is reserved between the loading slope block and the ground in a natural state; and meanwhile, the device can make contact with the ground when needed, and great convenience is provided for sliding loading of electromechanical equipment.

The utility model relates to the technical field of dyeing, in particular to a garment dyeing hanger with a quick discharging structure, which comprises a hanger rod, at least one group of limiting pieces and a push rod, the limiting pieces are equidistantly arranged along the inner circumference of the hanger rod, and the push rod is inserted into the hanger rod. Through an assembly composed of the hanging rod, the limiting piece and the push rod, a set of hanging tool capable of limiting the hanging position of clothes is provided for dyeing processing of ready-made clothes, the spacing between the clothes hangers is limited through the limiting piece, so that the spacing between the clothes hangers is guaranteed, the clothes are vertically immersed in a dyeing pool, and the clothes are not prone to being damaged. The adjacent clothes hangers cannot slide and displace, so that the situation that adjacent clothes are attached is avoided, the dyeing quality is guaranteed, meanwhile, the clothes hangers are effectively prevented from sliding out of the hanging rod, after dyeing is finished, the clothes hangers can be limited and unlocked, the clothes hangers can quickly slide out of the hanging rod, and the stability and convenience in the clothes hanging and dyeing operation period are guaranteed.

The utility model provides a guide structure for tinned wire processing, which belongs to the technical field of tinned wire production and comprises a tinning pool, a rotating roller, a feeding support, a discharging support and a guide roller, the rotating roller is rotatably arranged in the center of the inner side of the tinning pool through a bearing, and the feeding support is fixedly arranged on the left side of the upper surface of the tinning pool. A discharging support is fixedly arranged on the right side of the upper surface of the tinning pool, guide rollers are rotationally arranged in the center of the feeding support and the center of the discharging support correspondingly, first copper wire limiting grooves are formed in the guide rollers, belt wheels are fixedly arranged at the outer ends of the two guide rollers, the two belt wheels are sleeved with a transmission belt, and a motor is fixedly arranged at the inner end of the feeding support. The output end of the motor is fixedly arranged on the guide roller, and electric telescopic rods are fixedly arranged above the feeding support and the discharging support correspondingly. According to the device, the tightness of all copper wires on the device can be adjusted, the tightness of a certain copper wire can also be adjusted independently, it is guaranteed that the copper wires stably pass through an underground pool, and the tinning quality is guaranteed.

The utility model discloses a ball valve relates to valve technical field, include: ball valve body, the valve core of ball valve body is equipped with the rotation groove that matches with the support shaft of ball valve body, and the support shaft rotation sets up in the rotation groove, and the groove bottom of rotation groove is provided with first permanent magnet, and the one end of support shaft is close to rotation groove and is provided with second permanent magnet corresponding first permanent magnet, and first permanent magnet and second permanent magnet are same pole and are opposite and set, and first permanent magnet and second permanent magnet interval setting, the repulsion of two permanent magnets is used in the utility model, and the force in the direction of the valve core is provided away from the support shaft, to offset the gravity of valve core, can guarantee that two permanent magnets have certain interval, avoid the wear and tear between valve core and support shaft caused by the downward movement of valve core, and the friction force of valve core and valve seat lower half increases, and the problem of aggravating wear and tear, can effectively reduce the wear and tear that valve core and valve seat bear, improve the service life of ball valve.

The present invention relates to the field of heat treatment technology, and in particular, to a heating device. The device comprises a furnace body assembly and a heating assembly. The furnace body unit in the furnace body assembly comprises a sealing door and a furnace wall. The heating assembly comprises a sleeve unit and a heating unit. The sleeve unit is connected in a hollow cavity of the furnace wall. The heating unit comprises a heating module and an insulating module. The heating module is connected in the hollow cavity of the sleeve unit. The heating module and the sleeve unit are arranged at intervals. The insulating module is connected to the heating module. A plurality of insulating modules are arranged in sequence along the axial direction of the heating module. The outer diameter of the insulating module is larger than the outer diameter of the heating module and smaller than the inner diameter of the sleeve unit. The central axis of the insulating module is arranged at intervals on the side of the central axis of the sleeve unit away from the heating area. The heating area is arranged in a space surrounded by the furnace wall, and the heating area and the heating assembly are arranged at intervals.
