Description

Technical Field

[0001] The utility model belongs to the technical field of traction, and particularly relates to a traction device for loading and unloading a non-powered vehicle. Background Art

[0002] A traction device for loading and unloading a non-powered vehicle generally refers to a device that moves and positions goods through external mechanical or manual force in the absence of a power source. Such traction devices are widely used in places such as warehouses, docks, and logistics centers to help improve loading and unloading efficiency and safety. A common traction device consists of a handle and a connecting rod, and moves the non-powered vehicle by manual pushing and pulling. It has a simple structure and low cost, but is suitable for short distances and lighter goods. Since the traction device in the related technology does not have the function of automatically locking and connecting with the vehicle to be moved, manual operation is required for each connection and disconnection of the traction device, resulting in the problem that frequent manual connection and disconnection operations will consume a large amount of time, reducing work efficiency. It is not only time-consuming and laborious, but also increases the complexity of operation and the probability of errors. Summary of the Invention

[0003] In view of this, the utility model aims to solve at least one of the related technical problems to a certain extent.

[0006] The two fixed frames are symmetrically arranged on the front end face of the traction frame. The transmission mechanism is arranged on the two fixed frames. One end of the transmission mechanism is fixedly connected to the top of the main shaft pin, and the other end of the transmission mechanism is connected to the output end of the drive mechanism. The drive mechanism is arranged on the rear end face of the traction frame. One end of the reset mechanism is connected to the main shaft pin, and the other end of the reset mechanism is connected to the outer end face of the traction frame;

[0007] The lead screw plate is arranged directly below the main shaft pin, and the inner end of the lead screw plate is fixedly connected to the traction frame;

[0008] The position detection sensor is arranged on the outer end face of the traction frame and is used to detect the position of the traction hook plate of the vehicle to be moved. The position detection sensor and the drive mechanism are both connected to the control mechanism;

[0009] The two protective plates are symmetrically arranged at the upper and lower ends of the traction frame, and the end of each protective plate away from the traction frame is fixedly connected to one of the mounting plates.

[0010] Further, a limiting hole is provided in the middle of the lead plate, and the limiting hole is arranged directly below the main spindle pin.

[0011] Further, a downward flanging is provided at the outer end of the lead plate, and two reinforcing ribs are provided at the position where the inner end of the lead plate is connected to the traction frame.

[0012] Further, the outer end of the lead plate and the bottom of the main spindle pin are both conical structures.

[0013] Further, the transmission mechanism includes a first rotating shaft, a second rotating shaft and two first synchronous belts. The first rotating shaft and the second rotating shaft are arranged in parallel on the two fixed frames. The first rotating shaft and the second rotating shaft are connected by the two first synchronous belts. The two first synchronous belts are symmetrically arranged. The top of the main spindle pin is fixedly connected to the middle of the first rotating shaft, and the output end of the driving mechanism is connected to the middle of the second rotating shaft.

[0014] Further, the reset mechanism includes a reset spring and a spring mounting seat.

[0016] Further, the position detection sensor is a photoelectric sensor, a proximity sensor or a limit switch.

[0017] Compared with the prior art, the traction device for unpowered vehicle loading and unloading of the present utility model has the following advantages:

[0018] 1. The kingpin is firmly fixed after connection, preventing accidental detachment or loosening during towing and movement, thus reducing the accident rate and improving the safety of the working environment. The automatic locking of the kingpin eliminates the steps of manual locking and unlocking. The operator only needs to simply insert and pull out to complete the connection and disconnection, greatly simplifying the operation process and reducing the operation difficulty. Since the automatic locking function can quickly achieve connection and unlocking, it reduces the time consumption caused by manual operation and improves the overall efficiency of loading and unloading operations. The automatic locking device can lock in the same way and with the same force each time, ensuring the consistency and stability of the connection and avoiding unstable factors caused by manual operation.

[0019] 2. The combination of the first rotating shaft, the second rotating shaft and the first synchronous belt is adopted to ensure efficient and stable power transmission, so as to achieve precise towing action. The two first synchronous belts are symmetrically arranged, making the force evenly distributed during the transmission process, reducing the eccentric load and mechanical stress concentration, and prolonging the service life of each component. The synchronous belt drive can avoid sliding friction, ensure the accuracy and repeatability of positioning, and improve the operation precision.

[0020] 3. The reset mechanism utilizes the cooperation of the reset spring and the spring mounting seat, and can automatically restore the kingpin and related components to the initial position after each operation without manual adjustment, simplifying the operation process and improving the work efficiency. The design of the reset spring and the spring mounting seat is relatively simple, the structure is compact, and the occupied space is small, which makes the overall design of the device more concise and cost-effective.
