Description

Technical Field

[0001] This utility model relates to the field of elevator technology, specifically to a structurally stable elevator guide rail base. Background Technology

[0002] Elevator guide rails are key components of elevators, consisting of car guide rails and counterweight guide rails. They come in three cross-sectional shapes: T-shaped, L-shaped, and hollow. They not only provide guidance but also withstand the impact forces generated during car and elevator braking, as well as the impact forces during emergency braking of the safety brake. During installation, to reduce pressure between the guide rails and the pit floor and avoid direct contact, guide rail bases are usually installed at the ends of the guide rails. This supports the guide rails, reduces pressure, prevents ground damage that could cause guide rail settlement, and allows for fixation and adjustment. However, in current technology, the guide rail bases cannot be adjusted after installation. When the supporting surface is not level, uneven stress on the guide rails can lead to deformation, affecting the smooth operation and ride comfort of the elevator, and shortening the service life of components such as the guide rails.

[0003] Chinese patent CN221916918U discloses an elevator guide rail base. This device secures the elevator car to its top via an elevator car mounting base. Two extension rods are located on each side of the base plate. A height adjustment mechanism is installed on the side of the extension rods furthest from the base plate, including a contact plate, base fixing bolts, an adjusting plate, and an adjusting hole. The adjusting positioning bolts are threadedly connected to the positioning threaded holes on the extension rods, enabling horizontal installation of the base plate on elevator shaft floors with varying left and right heights. The guide rail installation mechanism includes a fixed base plate and a guide rail adjustment mechanism. The fixed base plate has width adjustment holes, and the guide rail adjustment mechanism is threadedly connected to these holes via width adjustment bolts, allowing adjustment of the distance between the guide rails. The guide rail adjustment mechanism also includes an L-shaped support plate, a slide groove, a threaded rod, and a T-shaped adjusting plate. Rotating the handle rotates the threaded rod within the slide groove, causing the T-shaped adjusting plate to move back and forth, thus fine-tuning the guide rail position. Adjustment can be completed without removing the entire guide rail base, improving guide rail stability and elevator operation safety. However, the synchronization of the adjustment mechanism in this device is poor, and the elevator car may not be able to maintain alignment after adjustment.

[0004] Therefore, a synchronization mechanism needs to be added to the width adjustment mechanism and the guide rail adjustment mechanism. The synchronization mechanism increases the synchronicity between the width adjustment mechanism and the guide rail adjustment mechanism during the guide rail adjustment process, so that the elevator car remains centered during the installation process. Utility Model Content

[0005] To address the aforementioned issues, a structurally stable elevator guide rail base is provided. By inserting a bidirectional threaded rod through the first moving block, the first moving block can simultaneously move closer to or further away from the center position of the bidirectional threaded rod as it rotates. Furthermore, a synchronization mechanism is provided to simultaneously drive the unidirectional threaded rods within the first moving base at both ends of the bidirectional threaded rod to rotate synchronously. This solves the problem of poor synchronization during the adjustment process, which prevents the elevator car from being aligned after adjustment.

A limiting groove is located at the center of the moving groove, and the limiting block is located within the limiting groove. The first moving block has threaded holes, and two of the first moving block's holes are symmetrically arranged at both ends of the bidirectional threaded rod.

[0012] The advantages of this utility model compared to the prior art are:

[0013] 1. This utility model effectively solves the problem of poor synchronization of the adjustment mechanism in the prior art, which leads to the elevator car not being centered, by setting an elevator car placement base at the center of the guide rail base and cooperating with a width adjustment mechanism.

[0023] To further understand the features, technical means, and specific objectives and functions achieved by this utility model, the following detailed description of this utility model is provided in conjunction with the accompanying drawings and specific embodiments.

[0024] Reference Figures 1-6 As shown: 1. A structurally stable elevator guide rail base, comprising a guide rail base 1, an elevator car placement base 2, and a width adjustment mechanism 3, characterized in that: the elevator car placement base 2 is located at the center of the guide rail base 1; the width adjustment mechanism 3 includes a moving groove 31, a bidirectional threaded rod 32, a first moving block 33, and a first moving base 34; the moving groove 31 is opened along the long side of the guide rail base 1 at the center of the bottom of the guide rail base 1; the bidirectional threaded rod 32 is disposed in the moving groove 31, a limiting block is provided at the center of the bidirectional threaded rod 32, a limiting groove is provided at the center of the moving groove 31, and the limiting block is located in the limiting groove; the first moving block 33 has threaded holes, and the first moving block 33 has two symmetrically arranged holes passing through the two ends of the bidirectional threaded rod 32; the first moving block 33 has connecting holes; the first moving base 34 is installed on the first moving block 33 through the connecting holes.

[0025] The existing adjustment mechanism has poor synchronization, which may cause the elevator car to become misaligned during adjustment. To address this issue, the elevator car placement base 2 is fixed at the center of the guide rail base 1 to support the elevator car and ensure its stable placement. A limiting block is provided at the center of the bidirectional threaded rod 32, and a limiting groove is provided at the center of the moving groove 31. The limiting groove is located within the limiting groove. This design ensures that the bidirectional threaded rod 32 remains stable during rotation and prevents it from shifting. Since there are two first moving blocks 33 symmetrically inserted into the bidirectional threaded rod 32, when the bidirectional threaded rod 32 rotates, the first moving blocks 33 located on the left and right sides of the bidirectional threaded rod 32 will move towards or away from each other. The first moving base 34 is used for mounting the guide rail 53 and is mounted on the first moving blocks 33 through connecting holes, so the first moving base 34 moves synchronously with the first moving blocks 33. By rotating the bidirectional threaded rod 32, the first moving block 33 moves along the axial direction of the threaded rod, thereby driving the first moving base 34 to move, realizing width adjustment to adapt to elevator cars of different sizes, maintaining a tight fit between the guide rail 53 and the elevator car, and improving the stability and safety of elevator operation.

[0026] Reference Figures 1-4 As shown: The guide rail base 1 is provided with height adjustment mechanisms 4 on both sides; the height adjustment mechanism 4 includes an adjustment plate 41 and a ground contact block 42; protrusions extend outward from both sides of the guide rail base 1, and threaded holes are opened on the protrusions; several through holes are equally spaced along the long side of the adjustment plate 41, and bolts pass through the through holes and are threadedly connected to the threaded holes to install the adjustment plate 41 on the side of the guide rail base 1; the ground contact block 42 is located at the bottom of the adjustment plate 41 and is fixedly connected to the adjustment plate 41; the ground contact block 42 is in contact with the ground.

[0027] The guide rail base 1 is equipped with height adjustment mechanisms 4 on both sides to adapt to uneven elevator shaft floors and ensure the stability of the guide rail base 1. By adjusting the position of the bolts on the adjusting plate 41, i.e., changing the vertical position of the adjusting plate 41, the ground contact block 42 can be adapted to uneven ground, ensuring that the guide rail base 1 remains horizontal, thereby improving the stability and safety of the elevator guide rail.

[0028] Reference Figures 4-6 As shown: A guide rail adjustment mechanism 5 is provided on the first movable base 34; the guide rail adjustment mechanism 5 includes a one-way threaded rod 51, a second movable base 52 and a guide rail 53; the one-way threaded rod 51 is provided on the top of the first movable base 34 along the long side of the movable base; a through hole is provided at the bottom of the second movable base 52, and the one-way threaded rod 51 passes through the through hole into the second movable base 52; the guide rail 53 is installed on the second movable base 52.

[0029] The guide rail adjustment mechanism 5 is used to adjust the position of the guide rail 53 to fit the groove on the side of the elevator car that mates with the guide rail 53. When the position of the guide rail 53 needs to be adjusted, the second moving base 52 moves axially along the one-way threaded rod 51 by rotating the one-way threaded rod 51, thereby moving the guide rail 53 and achieving the front-to-back adjustment of the guide rail 53. This design allows the guide rail 53 to flexibly adapt to the installation requirements of different elevator shafts, ensuring precise alignment between the guide rail 53 and the elevator car, and improving the smoothness and safety of elevator operation.

[0030] Reference Figures 1-6 As shown: A synchronization mechanism 6 is provided outside the guide rail adjustment mechanism 5; the synchronization mechanism 6 includes a first rotating rod 61, a second rotating rod 62 and a central rotating rod 63; the first rotating rod 61 and the second rotating rod 62 are respectively connected to the guide rail adjustment mechanism 5 located at both ends of the bidirectional threaded rod 32, and the first rotating rod 61 and the second rotating rod 62 are respectively rotatably connected to the unidirectional threaded rod 51 on the guide rail adjustment mechanism 5; the central rotating rod 63 is rotatably connected to the end of the first rotating rod 61 that is close to each other, and the central rotating rod 63 is rotatably connected to the end of the second rotating rod 62 that is close to each other.

[0031] As the central rotating rod 63 rotates, it drives the first rotating rod 61 and the second rotating rod 62 to rotate synchronously. Therefore, when the guide rail adjustment mechanism 5 on either side begins adjustment, the first rotating rod 61 or the second rotating rod 62 connected to it will also rotate accordingly. The central rotating rod 63 is rotatably connected to the ends of the first rotating rod 61 and the second rotating rod 62 that are close to each other, forming a linkage mechanism that allows the one-way threaded rods 51 on both sides to rotate synchronously. The synchronization mechanism 6 is detachable and can be removed after adjustment is completed.

[0032] Reference Figures 1-6 As shown: A housing 64 covering the synchronization mechanism 6 is installed outside the synchronization mechanism 6; a rotating groove 65 is provided on the housing 64, and a rotating block 66 is rotatably connected in the rotating groove 65; the rotating block 66 is fixedly connected to the central rotating rod 63.

[0033] The outer casing 64 protects the rotating parts. Rotating the rotating block 66 drives the central rotating rod 63 to rotate, thereby achieving synchronous adjustment of the guide rail 53 by the two side guide rail adjustment mechanisms 5.

[0034] Reference Figures 1-6As shown: both the bidirectional threaded rod 32 and the unidirectional threaded rod 51 are provided with a fixing mechanism 7 on their outer sides; the fixing mechanism 7 includes a fixing block 71 and a fixing slot 72; the end of the bidirectional threaded rod 32 protruding from the moving groove 31 and the end of the unidirectional threaded rod 51 protruding from the first moving base 34 are provided with the fixing slot 72; the fixing block 71 is inserted into the fixing slot 72; an auxiliary tool is provided on the bidirectional threaded rod 32; the auxiliary tool includes an auxiliary rod 8; the bidirectional threaded rod 32 can be rotated with the assistance of the auxiliary rod 8.

[0035] Inserting the fixing block 71 into the fixing slot 72 can fix the one-way threaded rod 51 and the two-way threaded rod 32, preventing them from rotating again. The auxiliary rod 8 has a plug that is adapted to the fixing slot 72, which can be inserted into the fixing slot 72 on the two-way threaded rod 32 to assist the rotation of the two-way threaded rod 32.

[0036] The elevator car placement base 2 is located at the center of the guide rail base 1, supporting the elevator car and maintaining its stability. The width adjustment mechanism 3 includes a moving groove 31, a bidirectional threaded rod 32, a first moving block 33, and a first moving base 34. The moving groove 31 is opened along the center of the bottom of the guide rail base 1, and the bidirectional threaded rod 32 is disposed therein. A limit block and a limit groove are located at the center to ensure stable rotation of the threaded rod. The first moving block 33 is symmetrically arranged at both ends of the bidirectional threaded rod 32 and is connected to the first moving base 34 through connecting holes to achieve width adjustment to accommodate elevator cars of different sizes. The height adjustment mechanisms 4 on both sides of the guide rail base 1 include an adjusting plate 41 and a ground contact block 42. The through hole on the adjusting plate 41 engages with the threaded hole on the protrusion and is connected by bolts. The ground contact block 42 abuts against the ground to adapt to uneven ground and keep the guide rail base 1 level. The guide rail adjustment mechanism 5 on the first movable base 34 includes a one-way threaded rod 51, a second movable base 52, and a guide rail 53. The one-way threaded rod 51 is located at the top of the first movable base 34, and a through hole at the bottom of the second movable base 52 allows the one-way threaded rod 51 to pass through, enabling the guide rail 53 to be adjusted back and forth. The synchronization mechanism 6 includes a first rotating rod 61, a second rotating rod 62, and a central rotating rod 63, ensuring that the guide rail adjustment mechanisms 5 on both sides are adjusted synchronously. The outer shell 64 of the synchronization mechanism 6 is provided with a rotating groove 65 and a rotating block 66. The rotating block 66 is fixedly connected to the central rotating rod 63, protecting the internal synchronization mechanism 6 and enabling synchronous adjustment. The fixing mechanism 7 on the outside of the bidirectional threaded rod 32 and the one-way threaded rod 51 includes a fixing block 71 and a fixing slot 72. The fixing block 71 is adapted to and inserted into the fixing slot 72 to fix the position of the threaded rod. The auxiliary rod 8 can assist the bidirectional threaded rod 32 in rotating. These components work together to improve the stability and adjustment accuracy of the elevator guide rail base, ensuring the safe operation of the elevator.
