The utility model provides a high-temperature copper bar traction device which comprises a supporting platform, two sliding rails are arranged at the upper end of the supporting platform side by side, a sliding seat is arranged between the two sliding rails in a sliding mode, a driving mechanism is arranged at the upper end of the supporting platform and connected with the sliding seat, and a clamping cavity is formed between the sliding seat and the supporting platform. Two clamping blocks are arranged in the clamping cavity side by side, a power mechanism is arranged above the two clamping blocks, and the power mechanism is connected with the two clamping blocks. When the copper bar enters the clamping cavity, the two clamping blocks can be driven by the power mechanism to get close to each other until the two clamping blocks abut against the two ends of the copper bar respectively, and then the sliding seat can be driven by the driving mechanism to be away from the forward extruder in the length direction of the sliding rail so as to pull the end of the copper bar. And the copper rod is not easy to bend or even distort. Manual traction of workers is replaced by traction of the traction device, and the traction device has the advantages of being high in automation degree and traction efficiency.

The invention relates to the technical field of medical instruments, and discloses a traumatic orthopedics department auxiliary traction device aiming at the problems of adjustment flexibility, fitting precision, operation convenience and adaptation range of an existing traction device, the traumatic orthopedics department auxiliary traction device comprises two tightening mechanisms surrounding the upper portion and the lower portion of a traumatic part respectively and used for fixing an affected limb; the clamping assembly is arranged in the tightening mechanism and is used for fixing the affected limbs of the patients with different body types; the two ends of the two telescopic traction mechanisms are connected with the two tightening mechanisms respectively, and the two telescopic traction mechanisms are located on the periphery of the wound part at intervals and used for pulling the wound part. A motor of the tightening mechanism drives a first gear and a second gear to conduct transmission, an Archimedes thread coil sliding groove of the second gear is combined to drive a sliding block to move, accurate tightening and loosening of a clamping assembly are achieved, and the problem that traditional manual traction is insufficient in accuracy is solved. The distance between the two tightening mechanisms can be accurately controlled by an adjusting assembly of the telescopic traction mechanism, and the treatment requirements of different wound parts are met.

This utility model relates to the technical field of tape traction equipment, specifically a tape feeding and traction device. The device includes a support frame with an open side. Inside the support frame is a vertically movable clamping plate used to press the end of the tape into the support frame. A control slot is provided at the top of the support frame, and a drive plate is fixedly connected to one side of the clamping plate. This utility model uses the clamping plate and support frame to fix the end of the tape. The movement of the support frame drives the tape end to move, allowing the traction rollers that guide the tape to separate in a smaller space. This allows the clamping plate and the tape end to pass between two close traction rollers, facilitating traction operations within the limited space of the equipment. Furthermore, because the entire end of the tape is fixed, the tape remains spread out during traction, preventing folding during manual traction.

The utility model discloses a medical electric lifting manual traction bed which comprises a bottom frame, the bottom frame is provided with a rod body structure extending downwards, the top of the bottom frame is provided with a front lifting arm and a rear lifting arm in a hinged mode, the upper end of the front lifting arm and the upper end of the rear lifting arm are connected with extension arms, the upper ends of the two extension arms are provided with a chest plate in a hinged mode, and the chest plate is connected with a traction device. A leg plate is arranged on one side of the chest plate in a hinged mode, a foot plate is arranged on the side, away from the chest plate, of the leg plate in a connected mode, and a head plate is arranged on the side, away from the leg plate, of the chest plate in a hinged mode. The problem that an existing traction bed provided in the background technology has certain limitation in use is solved. The traction structures of the head and the feet are inconvenient to adjust, and the use effect is affected.

The utility model discloses a traction device for a mine car to enter a tank automatically, which relates to the technical field of mine transportation equipment and comprises tracks and a mine car, a fixing frame is arranged between the two tracks, two ends of the inner wall of the fixing frame are respectively provided with two rotating rods in a rotating mode through bearings, and two ends of each rotating rod are respectively and fixedly provided with a chain wheel. Chains are connected between the two chain wheels of the two rotating rods, a connecting rod is fixed between the two chains, a push plate is fixed at the upper end of the connecting rod, a stress plate is fixed at the lower end of the mine car, anti-falling structures matched with each other are arranged on the push plate and the stress plate, an oiling mechanism is arranged at one end of each chain, and one rotating rod is connected with a driving assembly. The anti-disengaging structure comprises a first clamping block fixed to one side of the push plate, a second clamping block is arranged on one side of the stress plate, and the first clamping block is located above the second clamping block. According to the utility model, manual traction is not needed, the positioning is accurate in the traction process, the device is not easy to fall off from the mine car, and the problem of poor efficiency is solved.
