Description

Technical Field

[0001] This application relates to the field of elevator maintenance engineering technology, specifically an elevator track correction and fine-tuning mechanism. Background Technology

[0002] In the elevator guide rail installation industry, the guide rails need to be installed vertically in the elevator shaft. The current practice is to install each section of the elevator guide rail vertically using a plumb line in the shaft and then using guide rail brackets. To ensure the verticality of the elevator guide rails, the current method involves manually straightening and positioning them using tools such as wrenches. However, manually judging the verticality of the guide rails by sight often introduces errors, leading to increasingly larger deviations.

[0003] Therefore, this application provides an elevator track correction and fine-tuning mechanism to solve the above problems. Utility Model Content

[0004] This application provides an elevator track correction and fine-tuning mechanism, which aims to solve the problems mentioned in the background art, such as the poor accuracy of existing manual visual correction.

[0005] To achieve the above objectives, this application provides the following technical solution: an elevator track correction and fine-tuning mechanism, comprising a correction block detachably connected to the guide rail body, and a cavity formed on the correction block that matches the long side of the guide rail body.

[0006] The correction block is fitted onto the long side of the guide rail body through a cavity. Two flat plates for straightening the guide rail body are symmetrically arranged on two opposite surfaces of the inner wall of the cavity. The distance between the two flat plates matches the thickness of the guide rail body. The two flat plates are clamped on both sides of the outer wall of the guide rail body. Impact blocks for assisting in striking are fixedly installed at both ends of the outer wall of the correction block. In use, the two flat plates are installed in the cavity of the correction block, and then the correction block is fitted onto one end of the guide rail body, so that the two flat plates are clamped on the outer wall of the guide rail body. Then, a hammer is used to strike the impact blocks, allowing the correction block to easily move laterally along the length of the guide rail body. Since the space between the two flat plates is a standard straight line, during movement, the flat plates will press against minor misalignments and unevenness on the surface of the guide rail body, completing the leveling and correction. No manual visual judgment of the correction accuracy is required, making the operation more convenient and reliable.

[0007] Preferably, for easy replacement, the plate and the correction block are detachably connected. The plate has a non-fixed thickness structure. A convex groove is provided on the inner side wall of the cavity. A matching block is fixedly installed on the plate. The block is inserted into the groove to complete the detachable snap-fit ​​fixation, which is convenient for disassembly and assembly.

[0008] Preferably, in order to facilitate the movement of the entire plate, both ends of the plate are provided with chamfers adjacent to the outer wall of the guide rail body, and the inclination angle of the chamfers is 30°-45°, so as to facilitate correction and make it convenient and quick.

[0009] Preferably, for further correction, the correction block has two symmetrically distributed impact holes, and each of the two correction blocks is fixedly installed with an impact rod that matches the impact hole. The impact rod is inserted into the impact hole, and the axial extension direction of the impact rod is perpendicular to the length direction of the guide rail body, so as to perform longitudinal correction on some protruding parts and further improve the correction effect.

[0010] Preferably, in order to assist the movement of the calibration block, the calibration fine-tuning mechanism further includes an auxiliary movement mechanism. The auxiliary movement mechanism includes a support shaft fixedly installed on the outer wall of the calibration block, a bearing seat fixedly installed on the support shaft, and a pulley fixedly installed on the bearing seat. The pulley is in rolling connection with the outer wall of the guide rail body to assist the movement of the calibration block and facilitate movement.

[0011] This fine-tuning mechanism involves installing two flat plates inside the cavity of a calibration block, then inserting the calibration block from one end of the guide rail body, so that the two flat plates are clamped on the outer wall of the guide rail body. A hammer is then used to strike the impact block, allowing the calibration block to easily move laterally along the length of the guide rail body. Since the space between the two flat plates is a standard straight space, during movement, the flat plates will squeeze out the slight misalignments and unevenness on the surface of the guide rail body, completing the leveling and correction. There is no need for manual visual judgment of the correction accuracy, making the operation more convenient and reliable.

[0012] This fine-tuning mechanism presses and fixes the calibration block onto the guide rail body. By striking the impact block at one end of the calibration block with a hammer, the calibration block will move slightly along the long side of the guide rail body after being impacted. The calibration block is supported by pulleys, allowing it to move on the guide rail body via the pulleys. This reduces the friction between the bottom edge of the calibration block and the guide rail body, assisting the calibration block in moving and facilitating its movement.

[0019] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0020] Example 1

[0021] This embodiment provides an elevator track correction and fine-tuning mechanism, such as... Figure 1-4 As shown, the calibration and fine-tuning mechanism includes a calibration block 2 detachably connected to the guide rail body 1, and a cavity 21 formed on the calibration block 2 that matches the long side of the guide rail body 1.

[0022] The correction block 2 is fitted onto the long side of the guide rail body 1 through the sleeve cavity 21. Two flat plates 22 for straightening the guide rail body 1 are symmetrically arranged on two opposite surfaces of the inner side wall of the sleeve cavity 21. The distance between the two flat plates 22 is adapted to the thickness of the guide rail body 1. The two flat plates 22 are sandwiched on both sides of the outer side wall of the guide rail body 1. Impact blocks 23 for assisting in striking are fixedly installed at both ends on the outer side wall of the correction block 2.

[0023] In use, the two flat plates 22 are installed in the cavity 21 of the correction block 2, and then the correction block 2 is inserted from one end of the guide rail body 1, so that the two flat plates 22 are clamped on the outer wall of the guide rail body 1. Then, the impact block 23 is struck with a hammer, so that the correction block 2 can be easily moved laterally along the length of the guide rail body 1. Since the space between the two flat plates 22 is a standard straight space, when moving, the flat plates 22 will squeeze the slight skew and unevenness on the surface of the guide rail body 1 to complete the leveling and correction. There is no need to manually judge the correction accuracy with the naked eye, making the operation more convenient and reliable.

[0024] Specifically, the plate 22 and the correction block 2 are detachably connected. The plate 22 is a non-fixed thickness structure. A "convex" shaped slot 24 is provided on the inner side wall of the cavity 21. A card block 25 that matches the slot 24 is fixedly installed on the plate 22. The card block 25 is inserted into the slot 24.

[0025] When in use, since the thickness of some guide rail bodies 1 is not uniformly fixed, when calibrating different guide rail bodies 1, the plate 22 of different thicknesses can be replaced to change the spacing between the two plate 22s to match the thickness of the guide rail body 1. When replacing, the plate 22 is slid longitudinally directly, and the plate 22 slides along the slot 24 with the locking block 25 to complete the detachable locking and fixing, which is convenient for disassembly and assembly.

[0026] More specifically, the two ends of the flat plate 22 are provided with chamfers 26 adjacent to the outer wall of the guide rail body 1, and the inclination angle of the chamfers 26 is 30°-45°.

[0027] When in use, if the flat plate 22 with a horizontal edge slides directly on the surface of the guide rail body 1, the flat plate 22 will be directly blocked and difficult to move when it encounters the protruding part in front. By setting a chamfer 26 at the moving end edge of the flat plate 22, the edge of the flat plate 22 is guided to press against the protruding part of the guide rail body 1 where the problem occurs, so as to make correction convenient and quick.

[0028] Furthermore, two symmetrically distributed impact holes 27 are provided on the correction block 2. An impact rod 28 that is adapted to the impact hole 27 is fixedly installed on both correction blocks 2. The impact rod 28 is inserted into the impact hole 27, and the axial extension direction of the impact rod 28 is perpendicular to the length direction of the guide rail body 1.

[0029] When in use, the joint of the long side of the guide rail body 1 has high support strength, and it is difficult to correct it in one go by simply moving the whole plate 22 laterally. When the whole plate 22 is obstructed in lateral movement, the impact rod 28 can be struck with a hammer. The impact rod 28 drives the whole plate 22 to impact downward along the impact hole 27, and longitudinally correct some of the protruding parts, thereby further improving the correction effect.

[0030] Example 2

[0031] Unlike Embodiment 1, the bottom of the guide rail body 1 contacts the correction block 2, resulting in high friction and making it inconvenient to move after tapping. Therefore, the correction fine-tuning mechanism also includes an auxiliary moving mechanism 3. The auxiliary moving mechanism 3 includes a support shaft 31 fixedly installed on the outer wall of the correction block 2. A bearing seat 32 is fixedly installed on the support shaft 31, and a pulley 33 is fixedly installed on the bearing seat 32. The pulley 33 is in rolling connection with the outer wall of the guide rail body 1.

[0032] In use, the correction block 2 is pressed and fixed on the guide rail body 1. The impact block 23 at one end of the correction block 2 is struck by a hammer. After being impacted, the correction block 2 will move slightly along the long side of the guide rail body 1. The correction block 2 is supported by the pulley 33, so that the correction block 2 can move on the guide rail body 1 through the pulley 33. This reduces the friction between the bottom edge of the correction block 2 and the guide rail body 1, assists the correction block 2 in moving, and facilitates movement.

[0033] The above description is merely a preferred embodiment of this application, but the scope of protection of this application is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in this application, based on the technical solution and concept of this application, should be included within the scope of protection of this application.
