Abstract
Description
Technical Field
[0001] This utility model relates to the field of escalator technology, specifically a steel heavy-duty automatic escalator truss. Background Technology
[0002] With social development, escalators are widely used in public places. Their important structural component, the escalator truss, is divided into two types: integral and split. A split escalator truss consists of upper and middle parts, requiring a connecting structure for fixation. In the prior art, publication number CN220866878U discloses an escalator truss structure that solves the problem that existing escalator trusses cannot prevent oil leakage. This utility model discloses an escalator truss structure including a truss, support plates, support members, and a sealing plate. In this utility model, a sealing plate is provided at the bottom of one end face of the truss. The sealing plate is located at the end of the truss near the main unit, and it can seal the end of the truss. Thus, when the main unit leaks oil, the sealing plate and the truss can prevent oil from leaking out of the truss. While the above solution can solve the problem of oil leakage when the main unit leaks oil, the sealing plate and the truss can prevent oil from leaking out of the truss, and the various support members are connected to the support plate with screws, thus allowing the support plate to be stably installed inside the truss. However, the above-mentioned connection structure is simple, has a single function, and the connection is not tight. The bolts are easily affected by tensile and shear forces and are prone to loosening under vibration and impact, which poses a safety hazard. Therefore, we propose a steel heavy-duty escalator truss.

[0025] 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.
[0026] Please see Figure 1-5 A steel heavy-duty escalator truss includes two sets of escalator trusses 1. Each set of escalator trusses 1 has a bottom stabilizing frame 2 at one end. Several sets of load-bearing frames 4 are fixed to the bottom of each set of bottom stabilizing frames 2. A top stabilizing frame 3 is fixed to the bottom stabilizing frame 2 via the load-bearing frames 4. Extension rods 5 are fixed to both sides of the bottom stabilizing frame 2 near one end. Vertical side grooves 8 are provided at the ends of both sets of escalator trusses 1 corresponding to the bottom stabilizing frames 2. The escalator truss also includes:
[0027] The inlet groove 9 and the adjustment groove 10 are located in the side groove 8 and are used to install the bottom stabilizing frame 2 and the top stabilizing frame 3 on the escalator truss 1.
[0028] Two sets of bottom stabilizing frames 2 and top stabilizing frames 3 are slidably connected within two sets of side grooves 8. The two sets of escalator trusses 1, serving as the main supporting components of the escalator truss, each have a bottom stabilizing frame 2 at one end, and are fixedly connected to the top stabilizing frame 3 by several sets of load-bearing frames 4. This design allows the bottom stabilizing frame 2 and the top stabilizing frame 3 to form a stable whole, enhancing the load-bearing capacity of the escalator truss.
[0029] Both sets of escalator trusses 1 have an entry slot 9 at one end, and two sets of interconnected adjustment slots 10 are provided on both sides of the escalator trusses 1.
[0030] The entry groove 9 and the adjustment groove 10 are interconnected. The extension rod 5 is slidably connected in the entry groove 9 and the adjustment groove 10. The bottom stabilizing frame 2 and the top stabilizing frame 3 are both fixed with extension rods 5 near one end on both sides. The two sets of escalator trusses 1 are provided with vertical side grooves 8 at the ends corresponding to the bottom stabilizing frame 2. At the same time, two sets of interconnected adjustment grooves 10 are also provided on both sides of the escalator truss 1. The design of these structures allows the extension rod 5 to be slidably connected in the entry groove 9 and the adjustment groove 10, realizing the flexible connection and relative sliding between the upper and lower parts of the escalator truss.
[0031] Both sets of bottom stabilizing frames 2 are fixed with push-in blocks 14 at the top, and the push-in blocks 14 are in the shape of right triangles.
[0032] The bottom inner walls of the two sets of adjustment slots 10 are fixed with vertical circular bases 11. Adjustment springs 13 are fixed within the circular bases 11 corresponding to the bottom inner walls of the adjustment slots 10. Movable rods 12 are slidably connected within the circular bases 11. The interconnected design of the entry slot 9 and the adjustment slots 10, along with the vertical circular bases 11 fixed to the bottom inner walls of the adjustment slots 10, the adjustment springs 13, and the slidably connected movable rods 12, together constitute a fastening and adjustment system. When the escalator truss is subjected to external forces, this system can effectively absorb and disperse the force, maintaining the stability of the escalator truss. Simultaneously, by adjusting the sliding position of the movable rods 12 within the circular bases 11, the escalator truss can be fine-tuned to adapt to different installation and usage requirements.
[0033] The bottom of each of the two sets of load-bearing frames 4 is fixed with a semi-circular hinge seat 6 directly below the extension rod 5. The bottom of the hinge seat 6 has a stop hole 7 that matches the top of the movable rod 12. The top of the movable rod 12 is slidably inserted into the stop hole 7. This design not only enhances the structural strength of the escalator truss, but also allows the escalator truss to better distribute force when subjected to vibration and impact.
[0034] Working Principle: Two sets of escalator trusses 1 serve as the main supporting parts of the escalator truss. Each set has a bottom stabilizing frame 2 at one end, which is fixedly connected to the top stabilizing frame 3 by several sets of load-bearing frames 4. This design allows the bottom stabilizing frame 2 and the top stabilizing frame 3 to form a stable whole, enhancing the load-bearing capacity of the escalator truss. Extension rods 5 are fixed on both sides of the bottom stabilizing frame 2 and the top stabilizing frame 3 near one end. Vertical side grooves 8 are opened at the ends of the two sets of escalator trusses 1 corresponding to the bottom stabilizing frame 2. At the same time, two sets of interconnected adjustment grooves 10 are also opened on both sides of the escalator truss 1. The design of these structures allows the extension rods 5 to slide within the entry groove 9 and the adjustment groove 10, realizing flexible connection and relative sliding between the upper and lower parts of the escalator truss. The interconnected design of the entry groove 9 and the adjustment groove 10, as well as the vertical circular base 11, the adjusting spring 13, and the slidingly connected movable rod 12 fixed on the bottom inner wall of the adjustment groove 10, together constitute a fastening and adjustment system. When the escalator truss is subjected to external forces, this system can effectively absorb and disperse the force, maintaining the stability of the escalator truss. Simultaneously, by adjusting the sliding position of the movable rod 12 within the circular base 11, the escalator truss can be fine-tuned to adapt to different installation and usage requirements. A semi-circular hinge seat 6 is fixed at the bottom of the load-bearing frame 4, directly below the extension rod 5. The bottom of the hinge seat 6 has a stop hole 7 that matches the top of the movable rod 12. This design not only enhances the structural strength of the escalator truss but also allows it to better disperse forces when subjected to vibration and impact.
