Abstract
Description
Technical Field
[0001] This utility model relates to the field of trusses, specifically a truss reinforcement structure. Background Technology
[0002] The escalator truss is a key supporting structure of escalators. It is generally a frame structure made of metal materials (such as steel) and installed between floors of a building. Its shape usually matches the shape of the escalator, and the whole structure is inclined. Its main function is to support the various components of the escalator, including the steps, handrail system, and drive mechanism. For example, in large shopping malls, passengers frequently use escalators, and the escalator truss must bear the weight of the crowds and the equipment itself. Moreover, its design must take safety factors into account, ensuring that the escalator remains stable in both running and stationary states, without swaying or deformation, thereby ensuring passenger safety. The middle section of the escalator truss is generally horizontal after production, and there is usually an inclined transition section connecting the upper and lower floors at both ends. Therefore, there is a welding process between the horizontal section and the transition section. Thus, the strength of this position in the escalator truss is particularly critical. For this reason, we propose a truss reinforcement structure. Utility Model Content

[0019] 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.
[0020] Please see Figure 1-2 A truss reinforcement structure includes an escalator truss 1 with one end curving upwards. The escalator truss 1 is composed of multiple sets of upward-curving rods and horizontal rods connecting the multiple sets of upward-curving rods. Reinforcing structures are provided on both the upward-curving end and the horizontal end of the escalator truss 1. The reinforcing structures include fixed structures and telescopic components. Fixed structures are provided on the upward-curving rods on both the upper and lower sides of the escalator truss 1. The corresponding two fixed structures are connected by telescopic components. The telescopic components on the upward-curving end and the telescopic components on the horizontal end are connected by inclined fixing rods 12.
[0021] Furthermore, the fixing structure includes a snap-fit block 13, a fixing plate 4, and bolts 5. The snap-fit block 13 has a rectangular groove 3. The snap-fit block 13 is snapped onto the lifting rod of the escalator truss 1 through the rectangular groove 3, and the opening of the rectangular groove 3 faces the side of the two lifting rods facing away from each other. The other side of the snap-fit block 13 is threadedly connected to the fixing plate 4 through bolts 5. The fixing plate 4 locks the lifting rod inside the rectangular groove 3. During installation, multiple snap-fit blocks 13 are snapped onto the lifting part and the horizontal part of the lifting rod respectively, and then the fixing plate 4 is installed with bolts 5 for fixing.
[0022] Furthermore, the telescopic assembly includes two plug rods 8 and one socket rod 9. The two plug rods 8 are respectively plugged into both sides of the socket rod 9, and the two plug rods 8 are respectively connected to the corresponding snap-fit blocks 13.
[0023] Furthermore, a T-shaped circular block 6 is fixedly installed on the snap-fit block 13. An annular block 7 is rotatably set at the thin shaft position of the T-shaped circular block 6. The annular block 7 is fixedly connected to the plug-in rod 8. During assembly, according to the distance between the upper and lower lifting rods on the same side, the snap-fit blocks 13 on both sides are pulled up and down. Subsequently, the distance between the snap-fit blocks 13 and the distance between the plug-in rod 8 and the sleeve rod 9 changes. This device can adaptively adjust the distance between the upper and lower lifting rods on both sides of the truss to be reinforced as needed, which is convenient for use.
[0024] Furthermore, an inclined fixing rod 12 is installed between the top of the sleeve rod 9 at the raised end of the lifting rod and the bottom of the sleeve rod 9 at the horizontal end of the lifting rod via a connecting assembly.
[0025] Furthermore, the installation assembly includes a circular fixing block 10 integrally formed on the sleeve rod 9 and a bolt 2 11 that can be threaded onto the circular fixing block 10. Both ends of the inclined fixing rod 12 are provided with circular holes. The inclined fixing rod 12 is sleeved onto the corresponding circular fixing block 10 through the circular holes. The bolt 2 11 limits the end of the inclined fixing rod 12. The circular holes at the end of the inclined fixing rod 12 are aligned with the circular fixing blocks 10 on both sides and inserted. Then, the bolt 2 11 is threaded on for limiting and fixing.
[0026] Furthermore, the inclined fixing rod 12 is a telescopic rod. In actual use, since the tilting position and amplitude of the truss are different, the installation position of the reinforcement structure at the horizontal end and the tilting end of the truss is different. Setting the inclined fixing rod 12 to be telescopic can better adapt to the reinforcement work of different trusses.
[0027] Working principle: Based on the distance between the two upper and lower lifting rods on the same side, the locking blocks 13 on both sides are pulled up and down, and then the distance between the locking blocks 13 and the insertion distance of the plug rod 8 into the sleeve rod 9 changes. During installation, multiple locking blocks 13 are respectively locked at the lifting point and the horizontal point of the lifting rod. Then, the fixing plate 4 is fixed by bolt 1 5. The circular holes at the end of the inclined fixing rod 12 are aligned with the circular fixing blocks 10 on both sides and inserted. Then, the bolt 2 11 is threaded on for limiting and fixing. This device can effectively strengthen the bending and lifting position of the truss by adding two vertical connections at the horizontal end and the lifting end of the truss, and then adding an inclined connection at the two vertical connection points for reinforcement.
[0028] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
