Description

Technical Field

[0001] This utility model relates to the field of escalator technology, specifically to an escalator drive shaft support adjustment device. Background Technology

[0002] Escalators are fixed electrically driven devices that use the rotation of a drive shaft to drive the chain and steps in a cyclical manner to transport passengers. Therefore, the drive shaft plays a crucial role in the stability, safety, comfort, and noise level of the escalator. The rationality and ease of operation of its support and adjustment devices directly affect the assembly, maintenance efficiency, and final operating effect of the drive shaft.

[0003] Application No. 201010281359.2 discloses an escalator drive spindle, which includes a drive spindle support device. This support device is a traditional structure. The disadvantage of this structure is that it is inconvenient to maintain and replace later, requiring the removal of pins and readjustment and reset.

[0004] Application No. 202211375245.3 discloses an improved fixing device for drive spindle. This solution has been optimized based on the traditional type, but it still has certain limitations and inconveniences. For example, the overall structural strength is difficult to guarantee, and during disassembly, it can only be moved in a predetermined direction. There are many other related parts that need to be removed, which is relatively time-consuming and labor-intensive. Utility Model Content

[0021] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0022] To illustrate the technical solution described in this utility model, specific embodiments are described below.

[0023] Example

[0024] Please see Figure 1 , Figure 2 This embodiment provides an escalator drive spindle support adjustment device, including an escalator drive spindle 1, an escalator truss structure 2, and a support adjustment device 3. The escalator drive spindle 1 is fixed to the escalator truss structure 2 via the support adjustment device 3. The support adjustment device 3 includes a support base 31 and a spindle support disc 32. Figure 3 As shown, the connecting surface of the escalator truss structure of the support base 31 has a cavity 312, and the connecting surface of the escalator drive spindle of the support base 31 has a circular hole 313 that penetrates into the cavity 312. The circular hole 313 is adapted to the escalator drive spindle 1. The spindle support disc 32 is installed in the cavity 312 and meshes with the support base 31. The middle part of the spindle support disc 32 has a through hole 321 that communicates with the circular hole 313. The middle part of the truss plate 21 of the escalator truss structure 2 is connected to the escalator drive spindle 1 by the spindle axial adjustment bolt 4. The main shaft 1 abuts against the truss plate 21 of the escalator truss structure 2, which is connected and fixed to the main shaft support disc 32 by fixing bolts 5. The truss plate 21 of the escalator truss structure 2 is connected and fixed to the support seat 31 by locking bolts 6. The adjacent sides of the support seat 31 have extension blocks 311 protruding towards the truss plate 21 of the escalator truss structure 2. The extension blocks 311 have threaded holes, and the threaded holes are threaded with adjusting bolts 7. The adjusting bolts 7 are in the vertical direction and the horizontal direction, abutting against the truss plate 21 of the escalator truss structure 2.

[0025] The fixing bolts 5 are provided in a plurality of evenly distributed manner, and the number of fixing bolts 5 can be set according to requirements; in this embodiment, there are 4 bolts. The truss plate 21 of the escalator truss structure 2 is also connected and fixed to the main shaft support disc 32 by a plurality of evenly distributed threaded pins 8, further enhancing the connection firmness of the main shaft support disc 32.

[0026] Two locking bolts 6 are located on one side of the truss plate 21 of the escalator truss structure 2, and their function is to prevent axial movement of the support seat 31. The other side of the truss plate 21 of the escalator truss structure 2 is in contact with the support seat 31 by two upper and lower push rod bolts 9. The function of the push rod bolts 9 is to facilitate the disassembly of the support seat 31 from the main shaft support disc 32 during disassembly.

[0027] During spindle assembly, the spindle support disc 32 is first pre-fixed to the escalator truss structure 2 using fixing bolts 5. Then, the support seat 31, which is pre-fitted onto the escalator drive spindle 1, engages with the spindle support disc 32, and the locking bolts 6 are pre-tightened. Then, the spindle is finely adjusted from the front, back, left, and right directions by adjusting the adjusting bolts 7 and the spindle axial adjusting bolts 4. After the required positioning accuracy is achieved, the fixing bolts 5 and locking bolts 6 are tightened as required. Then, the threaded pins 8 are installed by preparing the pin holes. The top rod bolts 9 are pre-installed in the corresponding threaded holes of the escalator truss structure 2 for easy use when disassembly is required later.

[0028] When disassembling the main shaft, first pre-secure the escalator drive main shaft 1 with slings or other tools. Loosen the locking bolts 6 and adjusting bolts 7 of the support base 31, as well as the main shaft axial adjustment bolts 4. Then, use the push rod bolts 9 to push the support base 31 out until it detaches from the main shaft support disc 32. At this point, the hoisting equipment can be used to lift the main shaft away. The above disassembly process does not require loosening the main shaft support disc 32 and its fasteners, which provides accuracy and strength assurance for subsequent main shaft repositioning and avoids the need for readjustment and reinstallation of pins, which are required in traditional structures, after repositioning.

[0029] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
