Description

Technical Field

[0001] The utility model relates to the technical field of elevator components, in particular to a lifting and conveying component of an elevator. Background Art

[0002] Hoists are large-scale mechanical equipment that transports by changing potential energy, such as mine hoists and dam hoists. In a broad sense, elevators, overhead cranes, winches, stabilizers, cranes, hoists, etc. can all be called hoists. Hoists generally refer to large-scale mechanical equipment with high power and strong lifting capacity. The transportation process is completed by dragging the flexible wire rope and the transported goods up and down by power machinery. Wire rope is an indispensable and important part of lifting machinery. The main varieties are phosphate coated wire rope, galvanized wire rope, stainless steel wire rope, smooth wire rope, etc.

[0003] The workpiece can only reach the corresponding position point by moving up and down on the elevator, and then be pushed to the corresponding storage space. However, during the lifting and transportation process, the workpiece is often only supported and connected by a support table or two beams, and there is no corresponding protective barrier component. Once vibration deviation occurs during the transportation process, it will affect the normal transportation of the workpiece. Moreover, the lifting and transportation components move by sliding friction during the movement, and the friction resistance is large. Long-term work can easily cause greater wear to the structure, which is not conducive to improving the service life of the device. Utility Model Content

[0004] The purpose of the utility model is to provide a lifting and conveying component of an elevator to solve the technical problem that the workpiece is often only supported and connected by a support platform or two cross beams during the lifting and conveying process, and there is no corresponding protective isolation component. Once vibration deviation occurs during the transportation process, it will affect the normal conveying of the workpiece.

Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0027] Reference Manual Attached Figure 1-Figure 7 As shown, a lifting and conveying assembly of a hoist comprises: a frame 1; a power member 2, the power member 2 comprises a driving motor installed on both sides of the top of the frame 1, the output shaft of the driving motor extends to the first rotating tooth 3 and the second rotating tooth 4 respectively, the transmission shaft between the first rotating tooth 3 and the second rotating tooth 4 is installed with a central bearing 5 adapted thereto, and the first rotating tooth 3 and the second rotating tooth 4 are correspondingly connected with a driving chain;

[0028] The support member 6 includes a support platform 7 fixedly connected to the drive chain, the support platform 7 is arranged in an L-shaped strip shape symmetrical to the center of the frame 1, and a crossbeam 8 is fixedly installed at both upper and lower ends of the support platform 7, and a roller 9 movably connected to the inner wall of the frame 1 is installed on one side of the crossbeam 8.

This installation method can reduce friction and correct the conveying position of the workpiece, thereby further ensuring the accuracy of the moving position of the conveying component.

[0030] The drive motor and drive chain are combined with the present patent solution. The technical means are obvious to those skilled in the art. Therefore, they are not drawn accordingly in the accompanying drawings. The drive motor and drive chain are merely conventional transmission mechanisms, and are not necessary technical features for solving the technical problems in this solution.

[0031] Specifically, the lifting and conveying assembly of the elevator also includes a protective part 10, which includes a rotating cylinder 11 arranged around the frame 1. One end of the rotating cylinder 11 is movably connected to the frame 1 through a rotating shaft, and the other end is movably connected to the V-shaped plate 12. As the rotating cylinder 11 is started, the V-shaped plate 12 and the workpiece on the support platform 7 are limited or separated from each other. A bending plate 13 is welded on the frame 1 and placed at the corner of the support platform 7. Reinforcing ribs 14 are installed in the height direction of the bending plate 13, and a limited position cavity is formed between the bending plate 13, the V-shaped plate 12, the support platform 7 and the crossbeam 8.

[0032] refer to Figure 1 , Figure 6 and Figure 7 Both ends of the rotating cylinder 11 are provided with rotating grooves connected to the frame 1 and the V-shaped plate 12. One end of the V-shaped plate 12 is movably connected to the frame 1. Both sides of the outer wall of the frame 1 are connected with guardrails 15 by locking and fixing with stop pins. The guardrails 15 are installed and connected by locking and fixing with stop pins, which can facilitate the subsequent installation and disassembly of the guardrails 15. In addition, the rotating cylinder 11 rotates the V-shaped plate 12 by pushing, and the V-shaped plate 12 can provide multi-point contact to limit the front and rear ends of the workpiece, which can effectively increase the contact area, thereby ensuring a good limit protection effect.

[0033] In addition, the support platform 7 is arranged in an L-shaped strip shape that is symmetrical with the center of the frame 1. The shape setting of the above-mentioned support platform 7, on the one hand, provides a larger contact area to prevent overload and make the support balanced. On the other hand, it can also save materials, reduce costs, and have a certain aesthetic appeal. In conjunction with the crossbeam 8 on the support platform 7, the workpiece can be limited up, down, left, and right to prevent position deviation during transportation.

[0034] Specifically, a support member 6 and a protective member 10 are provided, and the support member 6 and the protective member 10 are used in conjunction with each other, which not only provide corresponding supporting force to the workpiece on the support platform 7, but also play a role of barrier protection for the periphery of the workpiece to prevent position deviation during movement, thereby affecting the stable transportation of the workpiece. At the same time, the support member 6 uses rolling friction during the up and down movement, which can effectively reduce friction and increase the service life of the device.

[0035] A bending plate 13 is welded on the frame 1 and placed at the corner of the support platform 7. The bending plate 13 on the frame 1 can also further limit the connection between the front and rear ends of the workpiece, thereby further improving the safety of the device. In addition, the stability of the connection of the structural parts can be increased by cooperating with the reinforcing ribs 14.
