Description

Technical Field

[0001] The utility model application relates to the technical field of protective devices, in particular to a conveying protective device for an elevator. Background Art

[0002] The elevator is a large-scale mechanical equipment that transports goods by changing potential energy. The transportation process is completed by dragging the flexible wire rope and the transported goods up and down by a power machine. It is widely used in the lifting of block, powder and short fiber solid materials in mining, metallurgy, machinery, building materials, chemical industry, rubber, medicine, electricity, grain, food and other industries.

[0003] During the lifting process, most materials are designed to be open for easy dumping. However, since it is often difficult to maintain stability during the lifting process and the lifting takes a certain amount of time, it is easy for debris to fall into the process. Traditional protective devices will affect the dumping of materials and the convenience of the elevator when operating. Summary of the invention

[0021] In order to make the purpose, features, and advantages of the present application more obvious and easy to understand, the technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the embodiments described below are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0022] Reference Figure 1 , Figure 2 and Figure 3 , a conveying protection device for an elevator comprises an elevator body 1 and an elevator frame 2, a material box 3 is arranged inside the elevator frame 2, a servo motor 6 is arranged on the outer surface of one side of the elevator frame 2, and the output end of the servo motor 6 rotates through the elevator frame 2 and is fixed on the rotating seat 4, the inner side of the elevator frame 2 is rotatably connected with the rotating seat 4, and the rotating seat 4 and the material box 3 are detachably fixed, and connecting blocks 5 are fixed on both sides of the material box 3, and the connecting blocks 5 are inserted in the rotating seat 4, and the rotating seat 4 and the connecting blocks 5 are fixed by bolts;

[0023] A support rod 9 is arranged inside the lifting frame 2 on the side of the material box 3, and the bottom surface of the support rod 9 is fixed on the lifting machine body 1. The top surface of the material box 3 is covered with a protective cover 7. Connecting blocks 5 are fixed on both sides of the material box 3, and the connecting blocks 5 are inserted in the rotating seat 4. The rotating seat 4 and the connecting blocks 5 are fixed by bolts, and a sliding sleeve block 8 is fixed on the side of the protective cover 7. The sliding sleeve block 8 is slidably sleeved on the support rod 9. A fixing screw 14 is fixed on the top surface of the support rod 9, and a threaded sleeve on the fixing screw 14 A limiting screw cover 15 is provided, and rectangular sliding holes cooperating with the support rod 9 are opened inside the lower block 11 and the upper block 12. The length of the limiting screw cover 15 is greater than the length of the sliding hole, and the height of the spring 13 is greater than the height of the material box 3. The lower block 11 and the upper block 12 are slidably sleeved on the support rod 9 above the sliding block 8 in sequence, and a spring 13 is sleeved on the support rod 9 between the lower block 11 and the upper block 12, and the upper and lower ends of the spring 13 are respectively fixed to the lower block 11 and the upper block 12.

[0024] Specifically, during assembly, the connecting blocks 5 on both sides of the material box 3 are engaged and inserted into the rotating seat 4 and fixed with bolts. The lifting machine body 1 drives the material box 3 to lift. When the material box 3 is lifted, the protective cover 7 is attached to the top surface of the material box 3 under the action of gravity. That is, as the material box 3 drives the protective cover 7 to lift to the top, the sliding sleeve block 8 moves to the bottom surface of the lower sleeve block 11. At this time, the servo motor 6 runs, and drives the material box 3 to rotate through the rotating seat 4 and the connecting block 5, which can drive the material box 3 to rotate, and the material When the box 3 rotates, the protective cover 7 continues to be squeezed, so that the protective cover 7 pushes the lower sleeve block 11 through the sliding sleeve block 8 to compress the spring 13 and move up, so that the material box 3 can complete the unloading. After unloading, the material box 3 rotates in the opposite direction driven by the servo motor 6, and the protective cover 7 is re-covered on the material box 3. When the spring 13 needs to be replaced, the limiting screw cover 15 is turned to separate the limiting screw cover 15 from the fixing screw 14, and then the lower sleeve block 11, the upper sleeve block 12 and the spring 13 can be directly removed from the support rod 9.
