Description

Technical Field

[0001] This utility model relates to the field of transmission equipment technology, and in particular to a device for preventing mechanical injury in transmission equipment. Background Technology

[0002] To ensure safety during conveyor operation, protective nets or plates are installed on both sides of the conveyor belt to prevent personnel from approaching it and thus avoid injury from the movement of the conveyor belt. However, since the installed protective plates only provide vertical protection, when the conveyor belt deviates and needs to be corrected, the constant protection of the plates creates obstruction, increasing the inconvenience of maintenance during the operation of the conveyor belt. Utility Model Content

[0003] The purpose of this invention is to address the shortcomings of existing technologies where protective plates obstruct the conveyor belt, increasing operational inconvenience during maintenance. The proposed invention provides a device to prevent mechanical injury to transmission equipment.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] A device for preventing mechanical injury to transmission equipment is designed, including a conveyor. Mounting blocks are fixedly connected to both ends of the conveyor frame. A rotating shaft is rotatably connected to the mounting block via bearings. A protective plate is fixedly connected to the rotating shaft. A connecting block is fixedly connected to each of the two protective plates. A positioning hole is provided on the connecting block, and a positioning rod is provided in the positioning hole. The positioning rod is adjusted by an adjustment mechanism.

[0006] Preferably, the adjusting mechanism includes a connecting ear fixedly connected to the conveyor frame, a threaded post threaded through the connecting ear, and the upper end of the threaded post fixedly connected to the positioning rod.

[0007] Preferably, a rotating block is fixedly connected to the lower end of the threaded column.

[0008] Preferably, the positioning rod has an abutting part, a spring is fixedly connected to the outer wall of the abutting part, a fixing block is fixedly connected to the end of the spring, the fixing block is fixedly connected to the conveyor frame, and the spring is in a compressed state.

[0009] Preferably, the abutting portion has an arc-shaped structure.

[0010] Preferably, a movable rod is fixedly connected to the abutting part, with one end of the movable rod fixedly connected to the abutting part and the other end passing through the fixing block.

[0011] The beneficial effects of the transmission equipment anti-mechanical injury device proposed in this utility model are as follows: the positioning rod and positioning hole are used to position the protective plate, ensuring the verticality of the protective plate. When the conveyor belt needs to be corrected and maintained, the positioning rod is disengaged from the positioning hole, releasing the restriction on the protective plate and allowing the protective plate to rotate. This avoids the obstruction caused by the height of the protective plate when it is in use, so as to maintain the conveyor belt. Attached Figure Description

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0018] Example 1: Refer to Figure 1-4The transmission equipment uses a device to prevent mechanical injury, including a conveyor 2. Mounting blocks 13 are fixedly connected to both ends of the conveyor 2 frame. A rotating shaft 12 is rotatably connected to the mounting blocks 13 via bearings. Protective plates 1 are fixedly connected to the rotating shaft 12. Connecting blocks 3 are fixedly connected to both protective plates 1. Positioning holes 14 are provided on the connecting blocks 3, and positioning rods 4 are installed within the positioning holes 14. A receiving groove is provided on the conveyor 2 frame. When the connecting blocks 3 rotate with the protective plates 1, the receiving groove allows the connecting blocks 3 to pass through. The positioning rods 4 are adjusted by an adjustment mechanism. The positioning rods 4 and positioning holes 14 serve to position the protective plates 1, ensuring their verticality. When conveyor belt correction and maintenance are required, the positioning rods 4 are disengaged from the positioning holes 14, releasing the restriction on the protective plates 1 and allowing them to rotate. This avoids obstruction caused by the height of the protective plates 1 during protection, facilitating conveyor belt maintenance.

[0019] The adjustment mechanism includes a connecting ear 6 fixedly connected to the frame of the conveyor 2. A threaded post 5 is threaded through the connecting ear 6. The upper end of the threaded post 5 is fixedly connected to the positioning rod 4. By rotating the threaded post 5, the position of the threaded post 5 in the connecting ear 6 is adjusted, thereby driving the positioning rod 4 to move, so that the positioning rod 4 disengages from or enters the positioning hole 14.

[0020] A rotating block 7 is fixedly connected to the lower end of the threaded column 5, which is used to control and drive the threaded column 5 to rotate.

[0021] Example 2: In Example 1, the vibration of the conveyor 2 during operation can easily cause the threaded post 5 to rotate, leading to the separation of the positioning rod 4 from the positioning hole 14. This causes the protective plate 1 to rotate, affecting its protective function. (Refer to...) Figure 1-4 As another preferred embodiment of this utility model, based on embodiment 1, the positioning rod 4 has an abutting part 11, and a spring 10 is fixedly connected to the outer wall of the abutting part 11. A fixing block 9 is fixedly connected to the end of the spring 10, and the fixing block 9 is fixedly connected to the frame of the conveyor 2. The spring 10 is in a compressed state. By using the restoring force of the spring 10, the abutting part 11 abuts and fixes the positioning rod 4. Because the threaded column 5 is fixedly connected to the positioning rod 4, it prevents the threaded column 5 from rotating when the conveyor 2 is working.

[0022] A movable rod 8 is fixedly connected to the abutment part 11. One end of the movable rod 8 is fixedly connected to the abutment part 11, and the other end passes through the fixed block 9. The movable rod 8 is used to grasp and pull the abutment part 11 to move.

[0023] When maintaining the conveyor belt, one person pulls the moving rod 8, which moves the abutment part 11 to release the fixation of the positioning rod 4. At the same time, the threaded column 5 is rotated to move the positioning rod 4, so that the positioning rod 4 is disengaged from the positioning hole 14. Another person holds the protective plate 1. After the limit on the protective plate 1 is released, the protective plate 1 is rotated outward to make the protective plate 1 upside down.

[0024] Example 3: Reference Figure 3 As another preferred embodiment of the present invention, based on embodiment 2, the abutment part 11 has an arc-shaped structure, which allows the abutment part 11 to fit against the positioning rod 4.

[0025] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
