Description

Technical Field

[0001] This utility model relates to the field of escalator balance adjustment technology, and in particular to an escalator balance adjustment device for elevator installation. Background Technology

[0002] During the installation of escalators, the steps, as the core component that directly carries passengers, have a crucial impact on the safe operation, stability, and service life of the escalator due to their installation accuracy. Among these factors, the front-to-back balance of the steps is one of the key indicators to ensure passenger safety and comfort. When the steps are unbalanced, that is, when there is a height difference between the front and rear ends of the steps, the forward and backward tilting of the steps may cause passengers to slip, trip, or fall while going up or down the escalator, posing a direct threat to their personal safety.

[0003] Currently, during the installation of escalators, adjustments to address imbalances in the steps largely rely on manual operation. Installers typically use their experience to perform rough calibrations by tapping the step supports or adjusting the tension of the traction chain. However, the precision of manual adjustments is difficult to guarantee, as it is heavily influenced by the operator's skill level and subjective judgment, easily leading to over- or under-adjustment and making it difficult to control the imbalance of the steps within a reasonable range. Utility Model Content

[0004] The purpose of this utility model is to address the following shortcomings in the existing technology: during the installation of escalators, the adjustment of imbalance between the front and rear steps largely relies on manual operation. Installers usually rely on experience to perform rough calibration by tapping the step supports and adjusting the tension of the traction chain. However, the accuracy of manual adjustment is difficult to guarantee, and it is greatly affected by the skill level and subjective judgment of the operator, which can easily lead to over-adjustment or under-adjustment. It is difficult to control the imbalance of the steps within a reasonable range. Therefore, this utility model proposes an escalator balance adjustment device for elevator installation.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] An escalator balance adjustment device for elevator installation includes a pedal, a side plate installed on the side of the pedal, a rotating seat fixedly installed on the lower surface of the pedal, a support shaft rotatably installed on the rotating seat, and mounting plates symmetrically fixedly installed on the support shaft;

[0007] Both mounting plates are horizontally slidably mounted with movable seats via adjustment components. Both movable seats are rotatably mounted with support rods. Mounting blocks are symmetrically fixedly mounted on the lower surface of the pedal. The ends of the two support rods away from the movable seats are rotatably connected to the two mounting blocks respectively.

[0008] Both ends of the side plate are provided with mounting ports, and auxiliary wheels are installed in both mounting ports through mounting components.

[0009] Preferably, the adjustment assembly includes a threaded rod that is horizontally rotatably mounted on the mounting plate and a drive motor that is fixedly mounted on the mounting plate. One end of the threaded rod is fixedly connected to the output end of the drive motor, and the movable seat is threadedly sleeved on the threaded rod.

[0010] Preferably, the mounting plate has a strip-shaped hole along the axial direction of the threaded rod, and the movable seat is slidably mounted in the strip-shaped hole.

[0011] Preferably, the mounting assembly includes a fixed block rotatably mounted on the inner wall of the mounting opening, a movable plate mounted on the fixed block, and a fixed shaft fixedly mounted on one side of the movable plate. The auxiliary wheel is rotatably mounted on one end of the fixed shaft. A rectangular groove is provided at one end of the fixed block, and one end of the movable plate is slidably mounted in the rectangular groove.

[0012] Preferably, the surface of the fixed block is provided with a movable hole that communicates with the rectangular groove, and a limit block is slidably installed in the movable hole, the limit block being fixedly connected to the movable plate.

[0013] Preferably, the support shaft and the pedal are parallel to each other, and the length of the support shaft is greater than the length of the pedal.

[0014] The beneficial effects of this utility model are as follows:

[0015] By adjusting the components, the movable seat slides along the mounting plate, and then the strut pushes the pedal to rotate around the support shaft, precisely adjusting the tilt angle of the pedal. Compared with the traditional method of manually tapping and adjusting based on experience, this method effectively reduces the influence of the operator's skill level and subjective judgment, and can control the pedal imbalance within a more reasonable range, significantly improving the adjustment accuracy.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0022] Reference Figures 1-2 An escalator balance adjustment device for elevator installation includes a pedal 1, a side plate 2 installed on the side of the pedal 1, which together form the main frame of the device, a rotating seat 3 fixedly installed on the lower surface of the pedal 1, a support shaft 4 rotatably installed on the rotating seat 3, and mounting plates 5 symmetrically fixedly installed on the support shaft 4.

[0023] The side plate 2 and the pedal 1 combine to form the main structure of the simulated step, which is easy to fit the shape of the actual escalator step. The rotating seat 3 provides rotational support for the support shaft 4, making the support shaft 4 the rotation center for adjusting the angle of the pedal 1. The rotational cooperation between the support shaft 4 and the rotating seat 3 provides a basis for adjusting the tilt angle of the pedal 1. The mounting plate 5 is symmetrically fixed on the support shaft 4, which not only provides a mounting carrier for the adjustment components, but also ensures the symmetry of the adjustment structure on both sides, avoiding adjustment deviation caused by unilateral force.

[0024] Two mounting plates 5 are horizontally slidably mounted with movable seats 6 via adjustment components. Two movable seats 6 are rotatably mounted with support rods 7. Mounting blocks 8 are symmetrically fixedly mounted on the lower surface of the pedal 1. The ends of the two support rods 7 away from the movable seats 6 are rotatably connected to the two mounting blocks 8 respectively.

[0025] When the movable seat 6 slides horizontally along the mounting plate 5, the two ends of the support rod 7 rotate around the movable seat 6 and the mounting block 8 respectively. Its length remains unchanged but its angle changes, thereby pushing or pulling the pedal 1 to rotate around the support shaft 4, thus precisely adjusting the tilt angle of the pedal 1. Compared with the traditional method of manual tapping and adjustment based on experience, this effectively reduces the influence of the operator's skill level and subjective judgment, and can control the imbalance of the pedal 1 within a more reasonable range, significantly improving the adjustment accuracy.

[0026] Reference Figure 4The adjustment assembly includes a threaded rod 10 horizontally rotatably mounted on a mounting plate 5 and a drive motor 11 fixedly mounted on the mounting plate 5. One end of the threaded rod 10 is fixedly connected to the output end of the drive motor 11. A movable seat 6 is threadedly fitted onto the threaded rod 10. A slotted hole is provided on the mounting plate 5 along the axial direction of the threaded rod 10. The movable seat 6 is slidably mounted in the slotted hole. When the drive motor 11 is working, it outputs torque, which drives the threaded rod 10 to rotate around its own axis through a coupling. Since the movable seat 6 is threadedly connected to the threaded rod 10, and the sliding of the movable seat 6 is restricted within the slotted hole of the mounting plate 5 and cannot rotate with the threaded rod 10, the rotational motion of the threaded rod 10 can be converted into the horizontal linear motion of the movable seat 6 along the slotted hole. The slotted hole guides the movable seat 6, ensuring that it slides stably along the axial direction of the threaded rod 10 and avoiding deviation.

[0027] Reference Figure 3 Both ends of the side plate 2 are provided with mounting ports. Each mounting port is equipped with an auxiliary wheel 9 by means of a mounting assembly. The mounting assembly includes a fixed block 12 rotatably mounted on the inner wall of the mounting port, a movable plate 13 mounted on the fixed block 12, and a fixed shaft 14 fixedly mounted on one side of the movable plate 13. The auxiliary wheel 9 is rotatably mounted on one end of the fixed shaft 14. One end of the fixed block 12 is provided with a rectangular groove. One end of the movable plate 13 is slidably mounted in the rectangular groove. The surface of the fixed block 12 is provided with a movable hole that communicates with the rectangular groove. A limit block 15 is slidably mounted in the movable hole and is fixedly connected to the movable plate 13.

[0028] When the steps are installed on the escalator frame, the two ends of the support shaft 4 on the tread 1 are installed on the large chains on both sides of the escalator frame. The large chains are used to drive the tread 1 to move. At the same time, the auxiliary wheels 9 at both ends of the side plate 2 are installed on the guide rails on both sides of the escalator frame. The guide rails are used to support the side plate 2 and the tread 1, so that the tread 1 remains horizontal.

[0029] The fixed block 12 is rotatably connected to the inner wall of the mounting opening, so that the auxiliary wheel 9 can adjust its own direction according to the tilt angle of the side of the escalator. When adjusting the balance of the step 1, the moving plate 13 will move relative to the rectangular groove, thereby ensuring that the auxiliary wheel 9 can roll stably on the track. When the moving plate 13 moves in the rectangular groove, it drives the limiting block 15 to slide in the moving hole, preventing the moving plate 13 from falling out of the rectangular groove.

[0030] The support shaft 4 is parallel to the step 1. The length of the support shaft 4 is greater than the length of the step 1. The parallelism between the support shaft 4 and the step 1 ensures that the tilt direction is stable when the step 1 rotates around the support shaft 4. The length of the support shaft 4 is greater than that of the step 1, which makes it easier to install one end of the support shaft 4 on the large chain of the escalator.

[0031] In this invention, when the pedal 1 needs to be balanced, the adjusting component drives the moving seat 6 to move. When the moving seat 6 slides horizontally along the mounting plate 5, the two ends of the support rod 7 rotate around the moving seat 6 and the mounting block 8 respectively. Its length remains unchanged, but its angle changes, thereby pushing or pulling the pedal 1 to rotate around the support shaft 4, thus accurately adjusting the tilt angle of the pedal 1. Compared with the traditional method of manual tapping and adjustment based on experience, this effectively reduces the influence of the operator's skill level and subjective judgment, and can control the imbalance of the pedal 1 within a more reasonable range, significantly improving the adjustment accuracy.

[0032] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
