Abstract
Description
Technical Field
[0001] This utility model relates to the field of elevator lifting technology, and in particular to a quick-release guide rail for an elevator lifting mechanism. Background Technology
[0002] The device that places counterweights in an elevator is called a counterweight system. It mainly consists of a counterweight frame and counterweight blocks. The guide rails of the counterweight frame are installed on the guide rail brackets in the shaft. The counterweight frame is connected to the car through traction ropes, which plays the role of balancing the weight of the car and part of the load. During operation, the guide rails of the counterweight frame slide up and down on the brackets continuously. The guide rails are made of high-hardness rubber. Under long-term load and friction, the guide rails will melt. After melting, they will cool and solidify. The guide rails need to be replaced regularly. The guide rails are deformed due to melting and stick to the installation position on the counterweight frame, making them difficult to remove, increasing the difficulty of replacement and reducing work efficiency. Utility Model Content
[0003] The purpose of this application is to provide a quick-release guide rail for an elevator lifting mechanism to solve the problems mentioned in the background art.
[0004] To achieve the above objectives, this application provides the following technical solution:
[0005] A quick-release guide rail for an elevator lifting mechanism includes a counterweight frame and a guide rail assembly installed at the end of the counterweight frame. Fixing blocks are fixedly installed at both the upper and lower ends of the supports on both sides of the counterweight frame. The guide rail assembly includes a clamping plate, a ceramic plate, and a slider. Both the ceramic plate and the clamping plate are U-shaped plates. The ceramic plate is embedded inside the clamping plate, and the slider is embedded inside the ceramic plate. A groove is formed at the center line of the slider. A fitting tube is fixedly installed on one outer wall of the clamping plate and inserted into the fixing block. The clamping plate and the fitting tube are vertically divided into two parts. Grooves are formed on both sides of the clamping plate, and fitting blocks are fixedly installed on both outer walls of the ceramic plate, with the fitting blocks embedded inside the grooves of the clamping plate.
[0006] Preferably, protrusions are fixedly installed on both sides of the outer wall of the fitting tube, and a hexagonal block is fitted onto the outside of the fitting tube. The inner wall of the hexagonal block has a groove corresponding to the shape of the protrusion. A mounting groove is formed through the end of the fixing block, the shape of which corresponds to the shape of the hexagonal block. The remaining part of the mounting groove corresponds to the shape of the fitting tube and the protrusion. The fitting tube and the hexagonal block are fitted inside the mounting groove, and the clamping plate abuts against the fixing block. The inner wall of the fitting tube has threads, and the fitting tube and the fixing block are fixed by bolts. The bolts pass through the end of the fitting tube, and the bolt nuts abut against the outer wall of the fixing block.
[0007] The beneficial effects of this utility model are: by setting a guide rail assembly, the slider is installed inside the ceramic plate. The ceramic plate is resistant to high temperature, and the slider is directly heated and melted, which can achieve the purpose of quickly removing the slider and improve work efficiency.

[0013] The preferred embodiments of this utility model will now be described in detail with reference to the accompanying drawings, so that the advantages and features of this utility model can be more easily understood by those skilled in the art, thereby providing a clearer and more definite definition of the scope of protection of this utility model. The directional terms mentioned in this utility model, such as "up," "down," "front," "back," "left," "right," "top," and "bottom," are only for reference to the accompanying drawings.

[0014] like Figures 1-4 The diagram shows a quick-release guide rail for an elevator lifting mechanism, comprising a counterweight frame 1 and a guide rail assembly installed at the end of the counterweight frame 1. Fixing blocks 3 are fixedly installed at the upper and lower ends of the supports on both sides of the counterweight frame 1. The guide rail assembly includes a clamping plate 2, a ceramic plate 4, and a slider 6. Both the ceramic plate 4 and the clamping plate 2 are U-shaped plates. The ceramic plate 4 is embedded inside the clamping plate 2, and the slider 6 is embedded inside the ceramic plate 4. A groove is formed at the center line of the slider 6. A fitting tube 7 is fixedly installed on one outer wall of the clamping plate 2, and the fitting tube 7 is inserted into the fixing block 3. The clamping plate 2 and the fitting tube 7 are vertically divided into two parts. Grooves are formed on both sides of the clamping plate 2, and fitting blocks 5 are fixedly installed on both outer walls of the ceramic plate 4, with the fitting blocks 5 embedded inside the grooves of the clamping plate 2.
[0015] Both sides of the outer wall of the fitting tube 7 are fixedly installed with protrusions 8. A hexagonal block 9 is fitted onto the outside of the fitting tube 7. The inner wall of the hexagonal block 9 has a groove, the shape of which corresponds to the shape of the protrusion 8. The end of the fixing block 3 has a through mounting groove 11, the shape of which corresponds to the shape of the hexagonal block 9. The rest of the mounting groove 11 corresponds to the shape of the fitting tube 7 and the protrusion 8. The fitting tube 7 and the hexagonal block 9 are fitted inside the mounting groove 11. The clamping plate 2 abuts against the fixing block 3. The inner wall of the fitting tube 7 has threads. The fitting tube 7 and the fixing block 3 are fixed by bolts 10. The bolts 10 pass through the end of the fitting tube 7, and the nuts of the bolts 10 abut against the outer wall of the fixing block 3.
[0016] Example: When the slider 6 needs to be replaced in the counterweight frame 1, the bolt 10 on the end face of the fixing block 3 can be removed by rotating it first. The clamping plate 2 and the fitting tube 7 can be pulled out from the mounting groove 11. The hexagonal block 9 can be removed from the fitting tube 7. The protrusion 8 can serve as a guide for the movement of the hexagonal block 9. The protrusion 8 fits into the mounting groove 11, which can fix the clamping plate 2 and make it stable. After removing the hexagonal block 9, the clamping plate 2 and the fitting tube 7 are separated from the center line. The ceramic plate 4 and the fitting block 5 are separated from the clamping plate 2. Then the ceramic plate 4 and the slider 6 can be placed into the heating furnace. The heating furnace melts the rubber slider 6. Since the ceramic plate 4 is resistant to high temperature, the ceramic plate 4 can be removed, cooled, and a new slider 6 can be reinstalled. Then the clamping plate 2 is spliced and then installed into the fixing block 3.
[0017] It should be noted that the parts not covered in this utility model are the same as or can be implemented using existing technology; the various drives in this utility model can be implemented by corresponding power structures such as cylinders, oil cylinders, electric cylinders, and motors in conjunction with connecting rods, guide rods, etc., and are not limited to the structures described in the specification and the drawings.
[0018] The embodiments described above are merely examples of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these modifications and improvements all fall within the protection scope of this utility model.
