This device facilitates adjustment of the welding distance between the two trusses, providing effective support to the side trusses without hindering their lifting and movement.

Description

Technical Field

[0001] This utility model relates to the field of escalator truss assembly technology, specifically to a vertical welding assembly device for escalator trusses. Background Technology

[0002] With social development, my country's domestic real estate and public transportation sectors have experienced significant growth. Consequently, the demand for escalators is showing a gradual upward trend. The escalator truss is the most important core component of an escalator.

[0003] Escalator trusses come in a wide variety of types and specifications, and the number of welds is enormous. In my country, escalator manufacturers typically use manual welding for production. Generally, the trusses on both sides of the escalator are welded and assembled first, and then the trusses at both ends are welded together using crossbeams and other welding methods to form the overall escalator truss. Because the elevator side truss is extremely heavy, it needs to be hoisted and welded using tools such as overhead cranes. However, this welding and assembly method makes it difficult to adjust the distance between the two trusses, and it cannot provide effective support for the two trusses. It is also inconvenient to weld crossbeams between the two trusses. If appropriate clamps are used to fix the side truss, multiple points need to be used to form a support structure for the side truss. After the elevator truss is welded, the support structure of the clamps will hinder the hoisting and movement of the elevator truss, making it inconvenient for users. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a vertical welding assembly device for escalator trusses, which solves the technical problems of inconvenient hoisting and welding of escalator side trusses in existing technologies.

[0005] To achieve the above objectives, this utility model provides the following technical solution: A vertical welding assembly device for escalator trusses includes a fixed base frame and several support components, each of which is movably mounted on the fixed base frame. The support assembly includes an adjustment module, two sets of support side frames, and several support modules. The adjustment module is slidably mounted on the fixed base frame, and the two support side frames are symmetrically mounted on the adjustment module. The adjustment module is used to adjust the distance between the two support side frames, and several support modules are evenly installed at the support side frames. The support module includes a movable seat and a rotating shaft. The movable seat is mounted on the support side frame via the rotating shaft, allowing the movable seat to swing on the support side frame. A support rod is provided on one side of the movable seat near the middle of the fixed base frame, and the support rod protrudes from the surface of the support side frame. A limit block is provided on one side of the movable seat away from the middle of the fixed base frame. The center of gravity of the movable seat is located at the support rod. A support block is provided at the bottom of the movable seat, and the support block abuts against the bottom of the movable seat.

[0006] Furthermore, the adjustment module includes a drive motor, a slide rail, a drive screw, and two slide blocks. The slide rail is slidably mounted on a fixed base frame, and the drive screw is rotatably mounted inside the slide rail. One end of the drive screw is connected to the drive motor via a coupling. The drive motor is fixedly mounted on the side end of the slide rail. Both slide blocks are slidably mounted inside the slide rail, and the slide blocks are threadedly connected to the drive screw. The support side frame is fixedly mounted on the slide blocks.

[0007] Furthermore, a sliding mechanism is provided at both ends of the slide rail. The sliding mechanism includes a connecting bracket, several movable guide wheels, and a guide rail. The guide rail is fixedly installed inside the side end of the fixed base frame. A connecting bracket is fixedly installed at the side end of the slide rail.

The movable guide wheels are engaged with the guide rail and are located between the guide rail and the fixed base frame, so that the support component is always connected to the fixed base frame.

[0008] Furthermore, the support modules at each of the aforementioned support components are located on the same horizontal plane.

[0009] Compared with the prior art, this utility model provides a vertical welding assembly device for escalator trusses, which has the following advantages: This escalator truss vertical welding assembly device places the escalator side trusses on the support modules of the two support side frames of the support assembly. The position between the two trusses is adjusted by adjusting the module so that the connecting components of the two trusses, such as the crossbeams, can be welded between the two trusses. After the two trusses are welded and fixed into a whole escalator truss, the truss can be lifted by an overhead crane. The truss can then push the support module to swing upward, so that the support module does not obstruct the lifting and movement of the truss. This device facilitates the adjustment of the welding distance between the two trusses, can form effective support for the side trusses, and does not hinder the lifting and movement of the truss.

[0012] 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.

[0013] Please see Figures 1 to 5 The present invention provides the following technical solution: A vertical welding assembly device for escalator trusses includes a fixed base frame 1 and several support components 2. Each support component 2 is movably mounted on the fixed base frame 1, so that the position of each support component at the fixed base frame 1 is adjustable. The support assembly 2 includes an adjustment module, two sets of support side frames 25 and several support modules 3. The adjustment module is slidably mounted on the fixed base frame 1, so that the position of the adjustment module at the fixed base frame 1 is adjustable. The two support side frames 25 are symmetrically mounted on the adjustment module. The adjustment module is used to adjust the distance between the two support side frames 25 to adapt to escalator trusses of different sizes. Several support modules 3 are evenly installed at the support side frames 25. The support modules 3 are used to support the side trusses of the escalator. The support module 3 includes a movable seat 31 and a rotating shaft 34. The movable seat 31 is mounted on the support side frame 25 via the rotating shaft 34, allowing the movable seat 31 to swing at the support side frame 25. A support rod 32 is provided at one end of the movable seat 31 near the middle of the fixed base frame 1, and the support rod 32 protrudes from the surface of the support side frame 25. A limit block 33 is provided at one end of the movable seat 31 away from the middle of the fixed base frame 1. The center of gravity of the movable seat 31 is located at the support rod 32, so that the movable seat 31 is always in a downward swinging tendency under the action of the support rod 32. A support block 35 is provided at the bottom of the movable seat 31, and the support block 35 abuts against the bottom of the movable seat 31. At this time, the support rod 32 is in a horizontal position. The limit block 33 is used to limit the swing range of the movable seat 31, preventing the movable seat 31 from swinging upwards excessively and unable to swing downwards to the middle of the fixed base under the gravity of the support rod 32.

[0014] The adjustment module includes a drive motor 21, a slide rail 22, a drive screw 23, and two slide blocks 24. The slide rail 22 is slidably mounted on the fixed base 1. The drive screw 23 is rotatably mounted inside the slide rail 22. One end of the drive screw 23 is connected to the drive motor 21 via a coupling. The drive motor 21 is fixedly mounted on the side end of the slide rail 22. The drive motor 21 can drive the drive screw 23 inside the slide rail 22 to rotate. Both slide blocks 24 are slidably mounted inside the slide rail 22, and the slide blocks 24 are threadedly connected to the drive screw 23. The two slide blocks 24 can move synchronously towards each other. The support side frame 25 is fixedly mounted on the slide block 24, and the two support side frames 25 can move synchronously towards each other with the slide block 24.

[0015] Sliding mechanisms are provided at both ends of the slide rail 22. The sliding mechanism includes a connecting bracket 26, several movable guide wheels 27, and a guide rail 28. The guide rail 28 is fixedly installed inside the side end of the fixed base frame 1. The connecting bracket 26 is fixedly installed at the side end of the slide rail 22. Several movable guide wheels 27 are rotatably installed on the connecting bracket 26. The movable guide wheels 27 are adapted to the guide rail 28 and can move on the guide rail 28. The movable guide wheels 27 are engaged with the guide rail 28 and are located between the guide rail 28 and the fixed base frame 1, so that the support component 2 always remains connected to the fixed base frame 1 and will not detach from the fixed base frame 1, thus preventing the support component 2 from tipping over when the side truss is placed on the support side frame 25. A corresponding locking mechanism can be provided at the sliding mechanism to lock each support component 2 to the fixed base frame 1, so that the sliding mechanism cannot move. Since the support component 2 itself has a large weight, the friction between the guide rail 28 and the movable guide wheels 27 is large, and each support component 2 will not move arbitrarily and requires manual force to push.

[0016] The support modules 3 at each support component 2 are located on the same horizontal plane so that the two trusses placed on the two support side frames 25 are at the same height, resulting in higher welding accuracy of the two trusses.

[0017] The specific implementation process is as follows: When using this escalator truss vertical welding assembly device, firstly, under the action of the sliding mechanism, each support component 2 is pushed to a suitable position on the fixed base frame 1. Then, the two side trusses of the escalator are hoisted to the support modules 3 at the support side frames 25 of each support component 2 by the overhead crane, so that the support rods 32 support the column side trusses in a suitable position. Next, the drive motors 21 of each support component 2 are started. The drive motors 21 drive the two slides 24 to move through the drive screws 23. The two slides 24 move synchronously towards each other. The two slides 24 drive the two support side frames 25 and the side trusses on the support side frames 25 to move together until the two side trusses move to a suitable position. Then, welding can be performed between the two side trusses through the beam mechanism to form the overall truss structure of the escalator. Then, the overall truss can be hoisted and moved by the overhead crane. During the upward movement of the overall truss, each support rod 32 can be pushed to swing upward under the action of the movable seat 31, so that the support rods 32 will not interfere with the movement of the overall truss.

[0018] This escalator truss vertical welding assembly device places the elevator side trusses on the support modules 3 of the two support side frames 25 of the support component 2. The position between the two trusses is adjusted by adjusting the module so that the connecting components of the two trusses, such as the crossbeam, are welded between the two trusses. After the two trusses are welded and fixed into an integral first-piece elevator truss, the truss can be lifted by an overhead crane. The truss can then push the support module 3 to swing upward, so that the support module 3 does not obstruct the hoisting movement of the truss. This device facilitates the adjustment of the welding distance between the two trusses, can form effective support for the side trusses, and does not hinder the hoisting movement of the truss.
