Technical Field

[0001] This utility model relates to the field of elevator truss assembly technology, specifically to an auxiliary 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, with a large number of welds. Domestic escalator manufacturers in my country generally use manual welding for production. When manually welding escalator trusses, a certain number of web members need to be welded between the two truss chords. The installation angle and position of these web members require manual positioning. Furthermore, the cutting of the web member ends introduces angular errors, leading to significant errors in the manual positioning of the web members during welding. This results in insufficient welding precision and inaccuracies in the welding angles of the web members between the two chords. This not only reduces the aesthetic appeal of the truss but also decreases its load-bearing capacity, failing to meet user requirements. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides an auxiliary welding and assembly device for escalator trusses, which solves the technical problem of angular errors in the manual welding of truss web members in existing technologies, and improves the welding accuracy and stress performance of escalator trusses.

[0005] To achieve the above objectives, this utility model provides the following technical solution: An auxiliary welding assembly device for escalator trusses includes a clamping module and a positioning module.

[0016] 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.

[0017] Please see Figures 1 to 2 The present invention provides the following technical solution: An auxiliary welding assembly device for escalator trusses includes a clamping module and a positioning module. The positioning module is installed on one side of the clamping module, such that when the clamping module is clamped at the truss chord 17, the positioning module is located on the side of the truss chord 17. The positioning module includes a positioning plate 6 and an adjustment mechanism. One end of the positioning plate 6 is hinged to the clamping module via a pivot, allowing the positioning plate 6 to swing at the side end of the clamping module. The adjustment mechanism is installed between the positioning plate 6 and the clamping module, and is used to adjust the positioning plate 6. The swing angle is adjusted to adjust the angle between the positioning plate 6 and the clamping module, so that the web member can connect with the truss chord 17 along the positioning angle of the positioning plate 6. The adjustment mechanism includes a threaded sleeve 9, a first screw 10 and a second screw 11. One end of the first screw 10 and the second screw 11 are respectively screwed into the threaded sleeve 9. The other ends of the first screw 10 and the second screw 11 are respectively connected to the side of the fixing clamping plate 4 of the clamping module and the positioning plate 6. When the threaded sleeve 9 is rotated, the first screw 10 and the second screw 11 can be screwed in and out of the threaded sleeve 9 at the same time, that is, the first screw 10 and the second screw 11 move towards each other.

[0018] The clamping module includes a top plate 1, a fixed clamping plate 4, and a movable clamping plate 12. The fixed clamping plate 4 is fixedly installed on one side of the top plate 1, and the fixed clamping plate 4 is distributed at a right angle to the top plate 1. The movable clamping plate 12 is installed on the other side of the top plate 1 through a clamping mechanism, and the movable clamping plate 12 is distributed at a right angle to the top plate 1. The clamping mechanism includes several guide rods 14 and several return springs 16. One end of the guide rod 14 is fixedly connected to the movable clamping plate 12, and the other end of the guide rod 14 is inserted into the slide groove 2 at the top plate 1. A limit block 15 is provided at the end of the guide rod 14 inserted into the slide groove 2. The limit block 15 ensures that the guide rod 14 is always inserted into the slide groove 2. A return spring 16 is sleeved on the guide rod 14. The return spring 16 is located between the guide rod 14 and the slide groove 2. The two ends of the return spring 16 abut against the limit block 15 and the end wall of the slide groove 2, respectively. Under the elastic force of the return spring 16, the movable clamping plate 12 always maintains the tendency to move towards the top plate 1.

[0019] The fixed clamp 4 and the movable clamp 12 are respectively provided with a first magnet 5 and a second magnet 13, so that the fixed clamp 4 and the movable clamp 12 can be attracted and attached to both sides of the truss chord 17.

[0020] Several third magnets 7 are installed at the positioning plate 6, so that the web rod can be attracted and attached to the positioning plate 6.

[0021] Several push-pull springs 8 are provided between the positioning plate 6 and the fixed clamping plate 4. One end of the push-pull spring 8 is fixedly connected to the positioning plate 6, and the other end of the push-pull spring 8 is fixedly connected to the fixed clamping plate 4. The push-pull spring 8 is used to assist the movement of the positioning plate 6.

[0022] The top plate 1, the fixed clamping plate 4, and the movable clamping plate 12 are evenly embedded with several ball bearings 3 on the side near the truss chord 17, which facilitates the movement of the clamping module along the chord.

[0023] The specific implementation process is as follows: When using this escalator truss auxiliary welding assembly device, firstly, the movable clamping plate 12 and the fixed clamping plate 4 are pulled apart. When the movable clamping plate 12 is pulled, it drives the guide rod 14 to extend from the slide groove 2 at the top plate 1, and causes the limiting block 15 to compress the return spring 16. Then, the clamping module is clamped at the truss chord 17, so that the fixed clamping plate 4 and the movable clamping plate 12 are clamped and adsorbed on both sides of the truss chord 17. At the same time, the top plate 1 and the top of the truss chord 17 abut against each other. Then, by rotating the threaded sleeve 9, the threaded sleeve 9 drives the first screw 10 and the second screw 11 to extend or retract, thereby adjusting the angle of the positioning plate 6 until the positioning plate 6 moves to the predetermined angle. Then, the web member to be welded is attached to the positioning plate 6, and the positioning plate 6 can position the web member and the truss chord 17. Finally, the truss chord 17 and the web member can be welded and fixed. After one web member is welded, the clamping module can be directly pushed along the truss chord 17 by the action of each ball bearing 3 until the device is moved to the installation position of the next web member.

[0024] One of these devices can be installed on each of the two truss chords 17, and the two ends of the web members can be positioned on the two truss chords 17 respectively.

[0025] This escalator truss auxiliary welding and assembly device uses a clamping module to clamp and install itself at the truss chord 17. By adjusting the adjustment mechanism, the angle of the positioning plate 6 is adjusted so that the web member fits against the positioning plate 6, thus achieving the connection angle positioning between the web member and the chord member. Subsequently, the truss chord 17 and the web member can be welded together using welding equipment. This device can effectively improve the welding and assembly accuracy between the truss chord 17 and the web member, enhancing the overall aesthetics and load-bearing performance of the truss. The support positioning module can effectively improve production efficiency during elevator truss production, meeting user needs.
