[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0017] like Figure 1As shown, a tension adjustment structure for a hoist head includes a head 1, a positioning plate 2 on the head, and a rotating shaft 3 rotatably connected to the positioning plate. A sprocket on the rotating shaft is located inside the head. This structure is an existing structure. Further, a connecting plate is provided on one side of the head, and a motor 14 is slidably connected to the connecting plate. The motor and the rotating shaft are connected by a transmission mechanism. A fixing frame 6 is also provided on the outside of the head, and a reinforcing rib 7 is provided between the fixing frame and the connecting plate. Preferably, the motor and the rotating shaft are connected by a belt drive structure.

[0018] The connecting plate is L-shaped, including a horizontal section 4 and a vertical section 5. The vertical section is connected to the machine head via a connector, and the motor is slidably connected to the horizontal section. Specifically, the end of the horizontal section away from the machine head has a horizontal inner groove on the side closer to the machine head. The motor is mounted on a base plate 8, which is inserted into the inner groove. A first vertical plate 9 is mounted on the base plate, and a second vertical plate 10 is mounted on the horizontal section. An adjusting component is located between the first and second vertical plates. The adjusting component includes an adjusting screw 11. A threaded hole is provided on the second vertical plate, through which the adjusting screw is screwed. A fixing hole is provided on the first vertical plate, through which the adjusting screw passes. Two sets of nuts 12 are screwed onto the adjusting screw hole, distributed on both sides of the first vertical plate. The nuts ensure the stability of the motor after adjustment. At least two sets of adjusting components are provided, arranged side by side.

[0019] Furthermore, an extension plate 13 is provided at the lower end of the horizontal section, moving away from the machine head, and the base plate is placed on the extension plate. A fixing screw hole is provided on the upper or lower end face of the horizontal section, connecting to a groove. A fixing bolt (not shown in the figure) is provided at the fixing screw hole, and the fixing bolt is used to tighten the base plate. The fixing bolt and the extension plate further improve the stability of the motor layout.

[0020] The working principle of this utility model is as follows: During the operation of the bucket elevator, the transmission belt connecting the motor and the rotating shaft inside the head may become loose. At this time, the position of the bottom plate is adjusted by adjusting the screw, thereby adjusting the position between the motor and the head to achieve tension adjustment of the transmission belt.
