Positioning calibration device for elevator guide rail wear survey

Abstract

This utility model relates to the field of elevator inspection technology, and more particularly to a positioning and calibration device for elevator guide rail wear inspection. The device includes a main body with a reinforcing block fixedly connected to its side surface. This positioning and calibration device for elevator guide rail wear inspection utilizes a second telescopic rod on the inner side of the clamping base plate within the inspection assembly to push an inspection clamping limit block to precisely clamp the elevator guide rail. Simultaneously, a cylindrical guide rod connected to the inspection clamping limit block guides the movement of the limit block, preventing it from shifting and ensuring that the inspection clamping limit block always adheres to the area of ​​the guide rail to be inspected, providing a stable clamping foundation for wear detection. The first telescopic rod adjusts the height and position of the limit rod, ensuring that the anti-slip fixing foot on one side of the limit rod tightly adheres to the elevator shaft floor or surrounding fixed structure. Combined with the support feet on the inspection base plate, this forms a multi-point stable support, preventing displacement of the device due to vibration or external forces during the inspection process.

Description

Technical Field

[0001] This utility model relates to the field of elevator inspection technology, and in particular to a positioning and calibration device for inspecting elevator guide rail wear. Background Technology

[0002] Elevator guide rails are the core guiding components in an elevator system used to guide the car and perform vertical lifting or tilting movements. They are usually made of metal and are installed on the inner walls of both sides of the elevator shaft or on specific track supports. They are key components that ensure the safe, stable and accurate operation of the elevator.

[0003] An investigation revealed that a Chinese utility model patent (CN212639625U) discloses an elevator guide rail calibration device for elevator maintenance. This device includes two symmetrically distributed guide rail bodies and a fixed calibration component. Two symmetrically distributed electrically controlled telescopic rods are movably connected to the left and right sides of the front end face of the fixed calibration component. The rear ends of two sliding blocks are slidably connected to the front ends of the two guide rail bodies. A balance rod is fixedly connected to a central plumb bob and a side plumb bob at the center below the two sliding blocks. When the guide rail body is in a vertical position, the laser lines emitted by the third laser pointers on both sides will penetrate the first correction through hole. When the guide rail body is not in a vertical position, the laser lines emitted by the third laser pointers on both sides are not on the same straight line and will not penetrate the first correction through hole. The elevator guide rail calibration device is simple to operate, convenient, quick, efficient, and of high quality, while reducing the labor intensity of elevator maintenance personnel.

[0004] When users use the above-mentioned patents, the overall adaptability is insufficient, and the stability and accuracy of the inspection are easily affected by the environment. The inspection clamping limit block lacks adaptability design for guide rails with different materials or surface conditions. If the guide rail surface is rough or has protrusions, it is easy to not fit tightly, or even scratch the guide rail surface. In addition, the adjustment function is not good enough, and there are problems such as clamping too loosely and easily shifting, or clamping too tightly.

[0005] Therefore, there is a particular need for a positioning and calibration device for investigating wear on elevator guide rails. Utility Model Content

[0006] The purpose of this invention is to provide a positioning and calibration device for inspecting wear on elevator guide rails, so as to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a positioning and calibration device for inspecting wear on elevator guide rails, comprising a device body, a reinforcing block fixedly connected to the side surface of the device body, a support plate fixedly connected to one side of the reinforcing block, a storage shell fixedly connected to one side of the support plate, and an inspection component installed on the front surface of the device body.

[0008] The surveying assembly includes a surveying base plate, which is mounted on the main body of the device. A first telescopic rod is fixedly connected to the front surface of the surveying base plate, a limit rod is fixedly connected to the front surface of the first telescopic rod, a support foot is fixedly connected to the front surface of the surveying base plate, and a mounting base plate is fixedly connected to the front surface of the surveying base plate. A clamping base plate is mounted on the front surface of the mounting base plate, and a second telescopic rod is fixedly connected to the inner side surface of the clamping base plate. A surveying clamping limit block is fixedly connected to one side of the second telescopic rod.

[0009] Preferably, a cylindrical guide rod is inserted into the inner side surface of the clamping base plate for limiting, and the cylindrical guide rod is connected to the inspection clamping limiting block.

[0010] Preferably, a limiting guide block is fixedly connected to one side of the cylindrical guide rod, and the limiting guide block and the clamping base plate are matched in size.

[0011] Preferably, a handle is fixedly connected to the side surface of the storage shell, and the handle is symmetrically arranged with the vertical center line of the device body as the axis of symmetry.

[0012] Preferably, the upper surface of the storage shell has a storage opening, and the number of storage openings is multiple.

[0013] Preferably, one side of the limiting rod is fixedly connected to an anti-slip fixing foot, and the anti-slip fixing foot is connected to the first telescopic rod through the limiting rod.

[0014] Preferably, the pallet is connected to the main body of the device via a reinforcing block, and the reinforcing block is symmetrically arranged with the vertical centerline of the main body of the device as the axis of symmetry.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] 1. In the inspection component, the second telescopic rod on the inner side of the clamping base plate can push the inspection clamping limit block to precisely clamp the elevator guide rail. At the same time, the cylindrical guide rod is connected to the inspection clamping limit block, which can guide the movement direction of the limit block and, together with the limit guide block, prevent the limit block from deviating, ensuring that the inspection clamping limit block is always in contact with the area to be inspected on the guide rail, providing a stable clamping foundation for wear detection. The first telescopic rod can adjust the height and position of the limit insertion rod, so that the anti-slip fixing foot on one side of the limit insertion rod is in close contact with the elevator shaft floor or surrounding fixed structure. Combined with the support feet on the inspection base plate, it forms a multi-point stable support, preventing the device from shifting due to vibration or external force during the inspection process. At the same time, the main body of the device is connected to the support plate through symmetrically arranged reinforcing blocks, which can distribute the weight of the support plate and the storage shell, avoiding deformation of the main body of the device under force on one side, further ensuring the positional stability of the inspection component and ensuring accurate and reliable wear inspection data.

[0017] 2. The storage shell, with symmetrically arranged handles on its sides, allows workers to easily hold the transfer device with both hands, eliminating the need for additional auxiliary tools and saving transfer time and labor costs. Multiple storage openings on the upper surface of the shell allow for the categorized storage of inspection tools, preventing them from being scattered or lost and facilitating quick retrieval during operations. From a practical standpoint, both the first and second telescopic rods are adjustable, adapting to elevator guide rails of different specifications and installation heights. Adjusting the first telescopic rod accommodates different shaft floor heights, while adjusting the second telescopic rod accommodates guide rails of different widths. This eliminates the need for custom-made inspection devices for different elevator models, reducing equipment investment costs. Furthermore, the anti-slip design of the fixed feet and the multi-point support structure allow the device to be stably placed in various complex environments within the elevator shaft, eliminating the need for additional fixed supports, reducing preparation time before operation, and improving overall inspection efficiency.

[0023] 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.

[0024] Please see Figure 1-4This utility model provides a technical solution: a positioning and calibration device for inspecting wear of elevator guide rails, including a device body 1, a reinforcing block 2 fixedly connected to the side surface of the device body 1, a support plate 4 fixedly connected to one side of the reinforcing block 2, a storage shell 5 fixedly connected to one side of the support plate 4, and an inspection component 3 installed on the front surface of the device body 1.

[0025] The survey component 3 includes a survey base plate 301, which is mounted on the main body 1 of the device. A first telescopic rod 302 is fixedly connected to the front surface of the survey base plate 301. A limit rod 303 is fixedly connected to the front surface of the first telescopic rod 302. A support foot 305 is fixedly connected to the front surface of the survey base plate 301. A mounting base plate 306 is fixedly connected to the front surface of the survey base plate 301. A clamping base plate 307 is mounted on the front surface of the mounting base plate 306. A second telescopic rod 308 is fixedly connected to the inner side surface of the clamping base plate 307. A survey clamping limit block 311 is fixedly connected to one side of the second telescopic rod 308.

[0026] Furthermore, a cylindrical guide rod 309 is inserted into the inner side surface of the clamping base plate 307 for limiting, and the cylindrical guide rod 309 is connected to the inspection clamping limiting block 311. The cylindrical guide rod 309 can move synchronously with the inspection clamping limiting block 311. When the second telescopic rod 308 pushes the inspection clamping limiting block 311 to clamp the guide rail, it provides stable movement guidance for the limiting block, avoiding lateral displacement or tilting of the limiting block due to uneven force, and ensuring that the inspection clamping limiting block 311 always remains parallel and in contact with the guide rail surface, thereby ensuring the positional accuracy of subsequent wear inspection. At the same time, the limiting insertion structure between the cylindrical guide rod 309 and the clamping base plate 307 can disperse the radial force borne by the second telescopic rod 308, reduce the deformation loss of the telescopic rod, and extend its service life.

[0027] Furthermore, a limiting guide block 310 is fixedly connected to one side of the cylindrical guide rod 309, and the limiting guide block 310 and the clamping base plate 307 are matched in size. The limiting guide block 310 can slide tightly against the inner side of the clamping base plate 307 when the cylindrical guide rod 309 moves with the inspection clamping limiting block 311, which can effectively limit the movement stroke of the cylindrical guide rod 309 and prevent the cylindrical guide rod 309 from detaching from the insertion hole of the clamping base plate 307, thus avoiding interruption of the clamping operation due to the component falling off. At the same time, the matching size design ensures that there is no excess gap between the limiting guide block 310 and the clamping base plate 307, which can further enhance the guiding stability of the cylindrical guide rod 309 and reduce the shaking of the inspection clamping limiting block 311 during the movement.

[0028] Furthermore, a handle 6 is fixedly connected to the side surface of the storage shell 5, and the handle 6 is symmetrically arranged with the vertical center line of the device body 1 as the axis of symmetry. The symmetrical handle 6 conforms to the ergonomic design, so that when the staff holds it with both hands, the force can be evenly distributed on both sides of the device body 1, avoiding the device tilting or center of gravity shifting due to single-handed holding. Especially when transferring the device in the narrow space of the elevator shaft, it can more easily control the direction of movement of the device and reduce the risk of collision. At the same time, the symmetrical layout balances the force points of the handle 6 and the device body 1, reduces the stress concentration at the connection between the handle 6 and the storage shell 5, prevents the handle 6 from loosening or breaking after long-term use, and ensures the safety of the equipment during the transfer process.

[0029] Furthermore, the upper surface of the storage shell 5 is provided with storage openings 7, and there are multiple storage openings 7. The multiple storage openings 7 can be used to classify and store survey tools such as thickness gauges, calibration rulers, recording pens, spare parts, etc., to avoid tools being mixed up and causing inconvenience in retrieval. During survey operations, staff can quickly retrieve the required tools from the corresponding openings, reducing the time spent searching for tools and improving work efficiency. At the same time, the opening design makes it easy to check whether the tools are complete at any time, and the size of the storage openings 7 can be adapted to the size of common survey tools to ensure that the tools are not easily shaken or fallen after being placed in them. The tools can be stably stored during the transfer of the device to avoid loss or damage.

[0030] Furthermore, an anti-slip fixing foot 304 is fixedly connected to one side of the limiting rod 303, and the anti-slip fixing foot 304 is connected to the first telescopic rod 302 through the limiting rod 303. The anti-slip fixing foot 304 is made of a high-friction coefficient material such as rubber or anti-slip plastic. After the first telescopic rod 302 is adjusted to a suitable length, it can fit tightly against the elevator shaft floor or the surface of the fixed bracket, thereby increasing friction to prevent the device from shifting due to vibration or slight external force during the inspection operation. At the same time, the anti-slip fixing foot 304 is connected to the first telescopic rod 302 through the limiting rod 303, and its height and angle can be flexibly adjusted with the first telescopic rod 302. It can adapt to uneven ground or inclined fixed structures in the shaft, ensuring that the device can still be stably fixed in complex environments.

[0031] Furthermore, the pallet 4 is connected to the main body 1 of the device via the reinforcing block 2, and the reinforcing block 2 is symmetrically arranged with the vertical center line of the main body 1 as the axis of symmetry. The symmetrical reinforcing block 2 can evenly transfer the weight of the pallet 4 and the storage shell 5 to the main body 1 of the device, avoiding deformation of the main body 1 or breakage at the connection due to unilateral force on the pallet 4. Especially when a lot of survey tools are stored in the storage shell 5, it can enhance the load-bearing capacity of the overall structure. At the same time, the connection structure of the reinforcing block 2 makes the connection between the pallet 4 and the main body 1 of the device more secure. During device transfer or survey operations, it can reduce the shaking of the pallet 4, thereby protecting the tools in the storage shell 5 from vibration and ensuring the overall stability of the equipment and tools.

[0032] Working principle: When a user needs to use a positioning and calibration device for inspecting wear on elevator guide rails, the operator holds the handles symmetrically arranged on the side surface of the storage shell 5 with both hands and moves the main body 1 of the device to the vicinity of the guide rail to be inspected in the elevator shaft. Then, through the multiple storage openings 7 on the upper surface of the storage shell 5, the inspection tools stored inside are taken out. At the same time, the inspection component 3 and other parts installed on the front surface of the main body 1 are checked to ensure that they are in their initial state and that there is no jamming or damage, thus preparing for subsequent inspection work. According to the installation height and position of the guide rail to be inspected, the first telescopic rod 302 fixed on the front surface of the inspection base plate 301 in the inspection component 3 is adjusted to lengthen or shorten the first telescopic rod 302, which drives the limit rod 303 fixed on its front surface to adjust its height, so that the anti-slip fixing foot 304 fixed on one side of the limit rod 303 is tightly attached to the elevator shaft floor or surrounding fixed structure.

[0033] Meanwhile, the support feet 305 and anti-slip fixing feet 304 fixed on the front surface of the survey base plate 301 form a multi-point support, which, together with the support plate 4 connected to the side of the main body 1 by symmetrical reinforcement blocks 2, ensures the overall stability of the main body 1 and the survey component 3, with no risk of displacement. After confirming that the device is fixed as a whole, the guide rail to be surveyed is clamped and calibrated: First, based on the mounting base plate 306 fixed on the front surface of the survey base plate 301, the second telescopic rod 308 on the inner side surface of the clamping base plate 307 installed on its front surface is activated, pushing the survey clamping limit block 311 fixed on one side to move in the direction of the guide rail; during this process, the cylindrical guide rod 309 that is limited and inserted on the inner side surface of the clamping base plate 307 moves synchronously with the survey clamping limit block 311, which plays a precise guiding role in the movement trajectory of the limit block and prevents deviation;

[0034] Meanwhile, the limiting guide block 310 fixed on one side of the cylindrical guide rod 309 slides against the inner side of the clamping base plate 307, preventing the cylindrical guide rod 309 from detaching from the clamping base plate 307, until the inspection clamping limiting block 311 is tightly attached to both sides of the guide rail, completing the stable clamping of the guide rail and the calibration of the inspection position. The staff uses the inspection tool taken from the storage opening 7, using the calibrated position of the inspection clamping limiting block 311 as a reference, to inspect the wear of the elevator guide rail. During the operation, because the device is fixed and stable as a whole and the guide rail is clamped accurately, it can ensure that the inspection tool and the area to be inspected on the guide rail are always kept in close contact. Stable contact is ensured to avoid deviations in survey data caused by device shaking, thus guaranteeing the accuracy of the survey results. After the survey of a single guide rail area is completed, the second telescopic rod 308 retracts, causing the survey clamping limit block 311, cylindrical guide rod 309, and limit guide block 310 to reset, releasing the clamp on the guide rail. Then, the first telescopic rod 302 is adjusted so that the anti-slip fixing foot 304 is removed from the shaft floor. The operator then grasps the handle 6 again to transfer the device to the next survey area or remove it from the elevator shaft. Finally, the survey tools are organized and placed into the storage shell 5 through the storage opening 7, completing the entire survey operation process.

[0035] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
