Description

Technical Field

[0001] This utility model relates to the field of elevator guide rail installation technology, and in particular to a pressure plate for elevator guide rails. Background Technology

[0002] The elevator guide rail clamping plate is a crucial connecting component in an elevator system used to fix and clamp the guide rails onto the bracket. During elevator installation, the guide rails need to be precisely fixed within the shaft to ensure the smooth operation of the car and counterweight. The clamping plate is connected to the bracket via bolts, and its own structural shape firmly clamps the guide rails in the preset position, thereby ensuring that the verticality, span, and joint accuracy of the guide rails meet stringent safety standards. Its design and manufacturing quality directly affect the rigidity and stability of the guide rail system, making it a vital fundamental component influencing the smoothness and safety of elevator operation.

[0003] A search revealed that patent CN216512261U discloses a pressure plate for elevator guide rails, which uses multiple inclined pressure blocks to further enhance the pressing effect on the top surface of the elevator guide rails, thereby further improving the lateral stability and reliability of the elevator guide rails.

[0004] However, the above-mentioned devices have the following drawbacks: First, current pressure guide plates are all integral structures. Once fixed, the contact surface position between the integral pressure guide plate and the guide rail is determined. When fine-tuning is required, workers can only rely on experience-based methods such as tightening bolts or hammering, which is inefficient, difficult to control in terms of precision, and cannot be adapted to guide rails of different thicknesses, resulting in poor versatility. Second, integral pressure guide plates are rigid connections. During elevator operation, the guide rail and shaft structure experience slight thermal expansion and contraction or vibration. Rigid pressure guide plates cannot effectively absorb these minute displacements and energy, easily leading to noise caused by hard friction between metal parts. Therefore, further improvements are needed. To this end, we propose a pressure guide plate for elevator guide rails. Utility Model Content

[0005] The purpose of this utility model is to overcome the shortcomings of the existing technology and propose a pressure plate for elevator guide rails.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a pressure plate for an elevator guide rail, comprising a mounting plate, a pressure plate, and a buffer pad. A connecting screw is fixed to the surface of the mounting plate. A through hole is provided at one end of the pressure plate, and the pressure plate is slidably sleeved onto the surface of the connecting screw through the through hole. A compression nut is rotatably connected to the surface of the connecting screw via a thread. The pressure plate is located between the mounting plate and the compression nut. The buffer pad is in contact with the surface of the pressure plate, and the buffer pad is located on the side closer to the mounting plate.

[0007] Furthermore, the mounting plate has a connecting hole at the end away from the connecting screw, and a connecting bolt passes through the connecting hole, with a nut rotatably connected to the surface of the connecting bolt.

[0008] Furthermore, the pressure plate surface is fixed with two vertical side edges, and the buffer pad is located between the two side edges.

[0009] Furthermore, a positioning block is provided on the surface of the pressure plate near the buffer pad, and a slot for engaging the positioning block is provided on the surface of the buffer pad.

[0010] Furthermore, the inner wall of the through hole is fixed with protruding teeth, and the side wall of the connecting screw is provided with a guide groove, the protruding teeth being located inside the guide groove and slidably connected with the guide groove.

[0011] Furthermore, a spring is sleeved on the surface of the connecting screw, and the spring is located between the mounting plate and the pressure plate, and the spring is fixedly connected to the mounting plate.

[0012] Furthermore, the pressure plate has multiple reinforcing ridges on the side surface away from the mounting plate.

[0013] The beneficial effects of this utility model are:

[0014] 1. In use, this utility model includes an installation plate, a pressure plate, a connecting screw, a buffer pad, connecting bolts, and a compression nut. The pressure plate is mainly composed of the installation plate and the pressure plate. After the installation plate is fixed to the guide rail bracket by the connecting bolts, the pressure plate is pressed by the compression nut, thereby using the pressure plate to press and fix the elevator guide rail. This installation method can be universally installed on guide rails of different thicknesses. In addition, the buffer pad replaces the pressure plate and directly contacts the guide rail, avoiding hard contact and achieving a silent effect.

[0015] 2. When using this utility model, an installation plate, connecting screw, pressure plate, compression nut and buffer pad are provided. The pressure plate and guide rail can be separated by turning the compression nut away from the installation plate. Then the buffer pad can be removed from the surface of the pressure plate, which is convenient for quick removal and replacement of the aged buffer pad during later maintenance.

[0022] 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 skilled in the art without creative effort are within the protection scope of the present utility model.

[0023] like Figures 1-3 As shown, a pressure plate for an elevator guide rail includes a mounting plate 1, a pressure plate 2, and a buffer pad 4. A connecting screw 3 is fixed to the surface of the mounting plate 1. A through hole 201 is provided at one end of the pressure plate 2, and the pressure plate 2 is slidably sleeved onto the surface of the connecting screw 3 through the through hole 201. A compression nut 7 is rotatably connected to the surface of the connecting screw 3 by a thread. The pressure plate 2 is located between the mounting plate 1 and the compression nut 7. The buffer pad 4 is in contact with the surface of the pressure plate 2, and the buffer pad 4 is located on the side closer to the mounting plate 1.

[0024] The mounting plate 1 has a connecting hole 101 at the end away from the connecting screw 3, and a connecting bolt 5 passes through the connecting hole 101. A nut 6 is rotatably connected to the surface of the connecting bolt 5.

[0025] When installing the mounting plate 1 using the connecting bolt 5, pass the connecting bolt 5 through the connecting hole 101 and then through the hole on the guide rail bracket. Then, screw the nut 6 onto the surface of the connecting bolt 5, thereby achieving a fixed connection between the mounting plate 1 and the guide rail bracket.

[0026] Two vertical side ridges 8 are fixed on the surface of the pressure plate 2, and the buffer pad 4 is located between the two side ridges 8.

[0027] In this embodiment, the buffer pad 4 is made of rubber, and the height of the buffer pad 4 is greater than the width of the pressure plate 2. The buffer pad 4 is horizontally limited by the side edge 8.

[0028] A positioning block 9 is provided on the surface of the pressure plate 2 and near the buffer pad 4, and a slot 401 for engaging the positioning block 9 is provided on the surface of the buffer pad 4.

[0029] When the buffer pad 4 is in contact with the pressure plate 2, the positioning block 9 engages with the slot 401, thereby further positioning and fixing the buffer pad 4. Therefore, when replacing the buffer pad 4 during later maintenance, the buffer pad 4 can be directly removed from the pressure plate 2.

[0030] When reinstalling the new buffer pad 4, simply place the buffer pad 4 between the two side edges 8 and make the positioning block 9 snap into the slot 401 on the surface of the buffer pad 4.

[0031] A protruding tooth 202 is fixed on the inner wall of the through hole 201, and a guide groove 301 is provided on the side wall of the connecting screw 3. The protruding tooth 202 is located inside the guide groove 301 and is slidably connected to the guide groove 301.

[0032] When the guide rail is pressed by the pressure plate 2 and the buffer pad 4, the pressing nut 7 on the surface of the connecting screw 3 is rotated, and the pressure plate 2 is pressed by the pressing nut 7. The pressure plate 2 will slide along the surface of the connecting screw 3. At this time, the protruding tooth 202 will slide along the guide groove 301, preventing the pressure plate 2 from rotating on the surface of the connecting screw 3, so that the pressure plate 2 always remains horizontal. Thus, the guide rail is pressed and fixed by the pressure plate 2 and the buffer pad 4.

[0033] A spring 11 is fitted on the surface of the connecting screw 3, and the spring 11 is located between the mounting plate 1 and the pressure plate 2. The spring 11 is fixedly connected to the mounting plate 1.

[0034] When it is necessary to remove and replace the buffer pad 4, turn the compression nut 7 in the opposite direction. The spring 11 will push the pressure plate 2 to separate from the mounting plate 1, so that the pressure plate 2 and the buffer pad 4 are both away from the guide rail. Then the buffer pad 4 can be removed from the surface of the pressure plate 2 for replacement.

[0035] Multiple reinforcing ribs 10 are provided on the surface of the pressure plate 2 away from the mounting plate 1. The reinforcing ribs 10 enhance the structural strength of the pressure plate 2, and the pressure plate 2 is used to press and fix the guide rail stably.

[0036] Working principle: The mounting plate 1 is fixed to the guide rail bracket by connecting bolts 5 and nuts 6. Rotating the compression nut 7 causes the pressure plate 2 to move along the connecting screw 3. Due to the sliding fit between the protruding teeth 202 and the guide groove 301, the pressure plate 2 is prevented from rotating, thus smoothly pushing the buffer pad 4 to press against the guide rail. Spring 11 provides preload between the mounting plate 1 and the pressure plate 2. When the buffer pad 4 needs to be replaced, loosening the compression nut 7 causes the restoring force of spring 11 to push the pressure plate 2 away from the mounting plate 1, allowing the buffer pad 4 to detach from the guide rail for direct replacement. The reinforcing ridges 10 on the surface of the pressure plate 2 ensure structural strength during the compression process.

[0037] The preferred embodiments of this utility model disclosed above are merely illustrative of the present utility model. These preferred embodiments do not exhaustively describe all details, nor do they limit the utility model to any specific implementation. Clearly, many modifications and variations can be made based on the content of this specification.
