Description

Technical Field

[0001] This utility model relates to the field of elevator guide rail assembly and disassembly technology, and in particular to an installation structure based on elevator guide rail. Background Technology

[0002] Elevator guide rails ensure that the car and counterweight run vertically along the predetermined track and prevent swaying. They also share the weight of the car and counterweight, as well as the dynamic forces during operation, which directly affects the smoothness, safety, and comfort of elevator operation.

[0003] If an elevator car is overloaded for a long period of time during operation, it can easily lead to an increase in the extra force on the elevator guide rails, which can cause the elevator guide rails to twist or deform. This can result in noticeable vibration, shaking, or metallic friction noise during elevator operation, and in severe cases, there may even be a risk of the car falling, thus reducing the comfort and safety of the elevator.

[0004] Currently, when elevator guide rails become twisted or deformed, the twisted or deformed sections need to be replaced. Existing elevator guide rails are typically connected to the load-bearing frame inside the elevator shaft via bolts. These bolts and nuts, which are exposed inside the elevator shaft for extended periods, are prone to rusting if the shaft is open-air or humid. This rusting can cause the bolts and nuts to stick together, resulting in a "seized" condition. When replacing the elevator guide rails, traditional disassembly tools (such as wrenches) cannot be used to separate the bolts and nuts; instead, they must be forcibly cut. This cutting process may damage the load-bearing frame and increases the time, effort, and complexity required for elevator guide rail replacement. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides an installation structure based on elevator guide rails, aiming to improve the problems in the prior art.

[0031] 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.

[0032] Reference Figure 1-5 The present invention provides an embodiment of an installation structure based on an elevator guide rail, comprising:

[0033] The load-bearing housing 1 has a load-bearing plate 2 detachably installed on one side. An elevator guide rail for guiding the car is fixedly installed on one side of the load-bearing plate 2. After the load-bearing plate 2 is connected to one side of the load-bearing housing 1, the load-bearing housing 1 and the inner wall of the elevator shaft are connected by expansion bolts. After two adjacent load-bearing housings 1 are connected to the inner wall of the elevator shaft, their ends come into contact with each other. By splicing multiple elevator guide rails together, the elevator guide rails can be assembled to guide and support the elevator car.

[0034] The receiving groove is opened on one side of the bearing housing 1 and communicates with the inner cavity of the bearing housing 1. Four receiving grooves are opened on one side of the bearing housing 1. The four receiving grooves are distributed in a rectangular structure, and a clamping plate 3 is slidably installed in the inner cavity of each of the four receiving grooves. The clamping plate 3 fixes the load-bearing plate 2.

[0035] The clamping plate 3 is designed with an L-shaped structure. When one side of the load-bearing plate 2 is attached to one side of the load-bearing shell 1, pressing the clamping plate 3 will allow the side wall of the clamping plate 3 to be attached to the side of the load-bearing plate 2 near the elevator guide rail. By blocking the two sides of the load-bearing plate 2 with the four clamping plates 3, the left and right limits of the elevator guide rail can be achieved.

[0036] When it is necessary to connect the load-bearing shell 1 and the load-bearing plate 2, first, the side of the load-bearing plate 2 away from the elevator guide rail is attached to the side of the load-bearing shell 1 with the receiving groove. Then, push the load-bearing plate 2 and slide it along the outer wall of the load-bearing shell 1. One end of the load-bearing plate 2 passes through multiple clamps 3 until both ends of the load-bearing plate 2 are flush with both ends of the load-bearing shell 1.

[0037] Limiting strips 11 are fixedly installed on the outer wall of the clamping plate 3. A fixing groove 7 that matches the limiting strip 11 is opened on one side of the load-bearing plate 2. Four fixing grooves 7 are opened on one side of the load-bearing plate 2. When one side of the four clamping plates 3 is attached to the side of the load-bearing plate 2 near the elevator guide rail, the four limiting strips 11 are respectively inserted into the inner cavity of the four fixing grooves 7, which can fix the load-bearing plate 2 and prevent the load-bearing plate 2 from detaching from the multiple clamping plates 3 due to the force on the elevator guide rail after the car is running. This improves the stability of the connection between the elevator guide rail and the load-bearing shell 1.

[0038] Both the load-bearing plate 2 and the limiting strip 11 are made of bearing steel, which improves the strength of the load-bearing plate 2 and the limiting strip 11. This prevents the limiting strip 11 from deforming due to prolonged compression between the outer wall of the limiting strip 11 and the inner wall of the fixing groove 7 after slight shaking of the elevator guide rail during car operation, thus preventing large-scale shaking of the elevator guide rail and improving the stability of the elevator car operation.

[0039] The length of the guide rail is the same as the length of the bearing housing 1. After the bearing housing 1 is welded to the load-bearing frame, the ends of two adjacent bearing housings 1 are fitted together. At this time, the ends of two adjacent elevator guide rails are fitted together to prevent large gaps between the ends of two adjacent elevator guide rails from causing vibration or shaking when the elevator car moves up and down.

[0040] The supporting housing 1 has multiple through holes 10 on both sides near the clamping plate 3, which communicate with its own internal cavity. Fixing columns 8 can be detachably installed in the internal cavity of the multiple through holes 10. Multiple sliding grooves are opened on one side of the multiple clamping plates 3. Multiple threaded holes are opened on both sides of the vertical plate 9 along the vertical direction. The opening ends of the sliding grooves, threaded holes and through holes 10 are on the same horizontal line. When the two ends of the elevator guide rail are flush with the two ends of the supporting housing 1, one end of the fixing column 8 is inserted into the internal cavity of the through hole 10. Then the fixing column 8 is continuously pushed until the inserted end of the fixing column 8 passes through the sliding groove and moves into the internal cavity of the threaded hole.

[0041] The fixing post 8 is designed as a T-shaped structure. The large end of the fixing post 8 has a groove that matches the hexagonal plate. When the small end of the fixing post 8 is inserted into the inner cavity of the threaded hole, one end of the hexagonal plate is inserted into the inner cavity of the groove, and then the rotation of the hexagonal plate can realize the rotation of the fixing post 8.

[0042] One end of the fixing post 8 is provided with a threaded groove that matches the threaded hole. When the insertion end of the fixing post 8 is inserted into the inner cavity of the threaded hole, the other end of the fixing post 8 is continuously rotated. As the fixing post 8 rotates, it moves continuously towards the vertical plate 9 along its own axis under the cooperation of the thread, until the insertion end of the fixing post 8 is in contact with the inner wall of the threaded hole away from its own opening end.

[0043] A bearing ring is rotatably installed on the outer wall of the fixed column 8. Two pressing blocks 12 are fixedly installed in a ring on the outer wall of the bearing ring. A force-bearing block 13 adapted to the pressing block 12 is fixedly installed on one side of the multiple clamping plates 3. One end of the force-bearing block 13 is inclined. As the fixed column 8 continues to move towards the vertical plate 9, one end of the pressing block 12 first contacts the inclined side wall of the force-bearing block 13. As the pressing block 12 continues to move, one end of the pressing block 12 moves along the inclined side wall of the force-bearing block 13, thereby applying a thrust to the force-bearing block 13 to move away from the receiving groove, which can move the upper and lower clamping plates 3. When the insertion end of the fixed column 8 and the threaded hole are in contact with the inner wall away from their own opening end, the movement distance of the clamping plate 3 is at its maximum value. At the same time, the side wall of the clamping plate 3 is in contact with the side of the load-bearing plate 2 near the elevator guide rail, thereby applying a thrust to the load-bearing plate 2 to move towards the load-bearing housing 1, which increases the friction between the load-bearing plate 2 and the load-bearing housing 1, thus realizing the connection between the load-bearing housing 1 and the load-bearing plate 2.

[0044] When the elevator guide rail needs to be replaced, first separate the bearing housing 1 from the elevator shaft, then continuously rotate one end of the fixing column 8 located inside the through hole 10 until one end of the fixing column 8 disengages from the internal thread hole, then pull out the fixing column 8 from the through hole 10, then pull the clamping plate 3 to extract the limiting strip 11 from the fixing groove 7, and then separate the bearing plate 2 from one side of the bearing housing 1, thus realizing the removal of the elevator guide rail, facilitating the replacement of the elevator guide rail, and reducing the time, energy and complexity required for replacing the elevator guide rail.

[0045] The fixing column 8, the extrusion block 12 and the stress block 13 can form an adjusting part for fixing the bearing plate 2. By means of the adjusting part, the clamping plate 3 can be pushed to move and the outer wall of the bearing plate 2 can be extruded, thus realizing the fixing of the bearing plate 2.

[0046] Since the thread hole is located inside the bearing housing 1, after one end of the fixing column 8 is fixed in the internal thread hole through the thread groove, the fixing column 8 and the thread hole can be internalized under the wrapping of the bearing housing 1, preventing humid air from entering the internal thread hole and causing rust on the inner wall of the thread hole and the fixing column 8, and avoiding the phenomenon of "jamming" due to adhesion between the outer wall of the fixing column 8 and the inner wall of the thread hole. When the bearing plate 2 is separated from the four clamping plates 3, it is convenient to rotate the fixing column 8 and take it out from the internal thread hole.

[0047] The through hole 10 is arranged in a "middle" - shaped structure. The length of the extrusion block 12 is not less than the depth of the through hole 10. When the small - end of the fixing column 8 is inserted into the internal thread hole, one end of the extrusion block 12 enters the internal cavity of the through hole 10. As the fixing column 8 continuously moves along its own axis direction, the bearing ring and the extrusion block 12 move together with the fixing column 8. At the same time, through the limitation of the through hole 10 on the extrusion block 12, it is prevented that the extrusion block 12 rotates together with the fixing column 8, and one end of the extrusion block 12 can contact the inclined side wall of the stress block 13 as the fixing column 8 moves.

[0048] A top - pressure spring is fixedly installed on the inner wall of the bearing housing 1 far from the accommodating groove. One end of the top - pressure spring is fixedly connected to one end of the clamping plate 3. When the clamping plate 3 moves under the continuous pressure of the extrusion block 12, the top - pressure spring is compressed and stores its own elastic potential energy. When one end of the extrusion block 12 disengages from the inclined side wall of the stress block 13, the top - pressure spring converts the elastic potential energy into the kinetic energy of the clamping plate 3 moving, enabling the clamping plate 3 to quickly reset, so as to facilitate the removal of the limiting strip 11 from the fixing groove 7.

[0049] A positioning strip 4 is fixedly installed on one side of the bearing housing 1. A limiting groove 6 that matches the positioning strip 4 is opened at one end of the load-bearing plate 2. When the two ends of the load-bearing plate 2 are flush with the two ends of the bearing housing 1, the positioning strip 4 is inserted into the inner cavity of the limiting groove 6 to limit the installation position of the load-bearing plate 2 and prevent the limiting strip 11 from being offset from the fixing groove 7, which would prevent the limiting strip 11 from being inserted smoothly into the fixing groove 7.

[0050] The side wall of the bearing housing 1 is provided with a mounting groove that communicates with the through hole 10. The central axis of the mounting groove coincides with the central axis of the through hole 10. A sealing cover plate 5 for sealing the through hole 10 is detachably installed in the inner cavity of the mounting groove. A rubber gasket is provided between the sealing plate 5 and the mounting groove. The rubber gasket can deform when squeezed to make up for the gap. When the small end of the fixing post 8 is in contact with the inner wall of the threaded hole away from its own opening end, the opening end of the sealing cover plate 5 is inserted into the inner cavity of the mounting groove. At this time, the outer wall of the sealing cover plate 5 and the inner wall of the mounting groove are tightly in contact. At the same time, the sealing cover plate 5 is wrapped around the outside of the large end of the fixing post 8. The through hole 10 can be sealed by the sealing cover plate 5 to prevent humid air from entering the inner cavity of the bearing housing 1 through the through hole 10 and causing rust to appear on the fixing post 8 and the inner wall of the threaded hole.

[0051] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
