Abstract
Description
Technical Field
[0001] This utility model relates to the field of escalator technology, and in particular to an escalator truss anti-deformation structure. Background Technology
[0002] The escalator truss is the basic framework of an escalator, used to support the overall weight of the escalator and the weight of the passengers. It is usually welded from materials such as angle steel, shaped steel, or square and rectangular tubes, and is a metal structural frame.
[0003] Escalator trusses are connected and supported by multiple sets of vertical and diagonal support rods. An installation frame needs to be reserved inside the escalator truss for installing guide rail components. The installation frame is usually installed between two sets of vertical support rods. The guide rail components are pre-assembled. During the transportation and lifting of the escalator truss, under the action of external forces, the escalator truss may deform and be damaged. The installation frame inside the escalator truss has poor support and is too easily deformed, failing to assist the support rods in supporting the escalator truss. This can easily lead to changes in the installation position of the guide rail components, potentially causing abnormal noises and affecting the stability of the steps during escalator operation. Utility Model Content
[0004] To address the aforementioned technical problems, the purpose of this utility model is to propose an anti-deformation structure for escalator trusses, which can enhance the deformation resistance of escalator trusses, effectively meet the usage requirements of escalator trusses, and is highly practical.
[0005] The technical solution of this utility model is implemented as follows: an anti-deformation structure for an escalator truss, comprising two sets of truss pieces arranged at relative intervals in a first direction; each truss piece includes an upper chord beam, a lower chord beam, and several side connecting beams connecting the upper chord beam and the lower chord beam;
[0006] A bottom connecting beam is provided for each of the side connecting beams; the bottom connecting beams connect between the lower chord beams on both sides;
[0007] Each bottom connecting beam is provided with an anti-deformation component; the anti-deformation component includes a mounting bottom beam, a mounting top beam, and a support frame; the mounting bottom beam is fixed on the bottom connecting beam; the mounting top beam is located above the bottom beam and connects to the side connecting beams on both sides;
[0008] The two support frames are arranged at a relative distance between the mounting bottom beam and the mounting top beam in the first direction, with the upper end of the support frame fixed to the mounting top beam and the lower end fixedly connected to the mounting bottom beam.
[0009] Furthermore, in the truss unit, diagonal support rods connect two adjacent side connecting beams.
[0010] Furthermore, the support frame has a Z-shaped structure; the two support frames have top sides facing each other and bottom sides facing away from each other; the top surface of the mounting bottom beam and the bottom surface of the mounting top beam are provided with limiting grooves extending in the first direction; the upper and lower ends of the support frame are inserted into the limiting grooves on the corresponding sides, and the top sides of the two support frames abut against each other, and the bottom sides of the two support frames abut against the two ends of the limiting grooves.
[0011] Furthermore, the anti-deformation component includes a first bolt; the upper end of the support frame and the mounting top beam, and the lower end of the support frame and the mounting bottom beam are locked and fixed by the first bolts that are inserted vertically.
[0012] Furthermore, the anti-deformation component includes a second bolt; the two ends of the mounting top beam and the side connecting beam are locked and fixed by the second bolt inserted along the first direction.
[0013] Furthermore, the anti-deformation component includes a third bolt; the two ends of the mounting base beam and the side connecting beam are locked and fixed by the third bolt inserted along the first direction.
[0014] Furthermore, the upper end of the side connecting beam is welded to the upper chord beam, and the lower end is welded to the lower chord beam.
[0015] Furthermore, the bottom connecting beam is welded to the lower chord beam.
[0016] Due to the application of the above technical solution, this utility model has the following advantages compared with the prior art:
[0017] 1. This utility model, through the connection and cooperation of side connecting beams, bottom connecting beams, and diagonal support rods, can provide connection and support for the overall structure of the escalator truss. With the cooperation of anti-deformation components, the side connecting beams and bottom connecting beams can be pulled and limited, and the support frame can provide tension support for the top and bottom mounting beams, thereby improving the assembly stability of the top and bottom mounting beams. The combination of the above methods can effectively enhance the deformation resistance of the escalator truss, effectively meeting the usage requirements of the escalator truss and demonstrating strong practicality.
[0018] 2. This utility model, by machining limiting grooves on the mounting bottom beam and mounting top beam, can limit the movement of the two support frames in the width direction of the limiting grooves. Furthermore, during assembly, the top sides of the two support frames abut against each other, and the bottom sides abut against the ends of the limiting grooves, thus restricting movement of the two support frames in the first direction (the length direction of the limiting grooves). The combination of these methods effectively limits the movement of the two support frames in both the length and width directions of the limiting grooves, preventing the support frames from sliding and generating shear force on the first bolt, thus effectively protecting the first bolt and significantly improving the stability of the first bolt connection. It is highly practical. Attached Figure Description

[0026] The preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings, so that the advantages and features of the present invention can be more easily understood by those skilled in the art, thereby making a clearer and more definite definition of the scope of protection of the present invention.
[0027] like Figure 1-5 The diagram illustrates an anti-deformation structure for an escalator truss as described in this embodiment. It comprises two sets of truss panels arranged at relative intervals along a first direction. The first direction refers to the width direction of the escalator or escalator truss. Each set of truss panels includes an upper chord beam 2, a lower chord beam 1, and several side connecting beams 3 connecting the upper chord beam 2 and the lower chord beam 1. The upper chord beam 2 and the lower chord beam 1 are conventional components in the elevator technology field, and their specific positions and functions are existing technologies. The aforementioned side connecting beams 3 are arranged at intervals along the length extension direction of the upper chord beam 2 or the lower chord beam 1. Specifically, the upper end of each side connecting beam 3 is welded to the upper chord beam 2, and the lower end is welded to the lower chord beam 1. A bottom connecting beam 9 is arranged corresponding to each side connecting beam 3. The bottom connecting beam 9 extends along the first direction and connects between the lower chord beams 1 on both sides. Specifically, both ends of the bottom connecting beam 9 are welded to the corresponding lower chord beam 1. Through the connection of the bottom connecting beams 9, the truss panels on both sides are connected into an integral structure.
[0028] In each of the aforementioned truss sections, an oblique support rod 4 connects two adjacent side connecting beams 3. This oblique support rod 4 is connected to the side connecting beam 3 by welding to strengthen the support.
[0029] Each bottom connecting beam 9 is equipped with an anti-deformation component. This anti-deformation component includes a bottom mounting beam 5, a top mounting beam 6, a support frame 7, a first bolt 71, a second bolt 61, and a third bolt 51. The bottom mounting beam 5 is arranged in the same direction as the bottom connecting beam 9 and is fixed to it. In the specific structural design, mounting holes corresponding to the bottom mounting beam 5 are machined in the side connecting beam 3 along a first direction. Threaded holes are machined at both ends of the bottom mounting beam 5 corresponding to the mounting holes. The bottom mounting beam 5 is locked and fixed to the side connecting beam 3 by inserting the third bolt 51 into the mounting holes and threading it into the threaded holes. The aforementioned top mounting beam 6 is arranged above the bottom beam and connects the two side connecting beams 3. In the specific structural design, mounting holes corresponding to the top mounting beam 6 are machined in the side connecting beam 3 along a first direction. Threaded holes are machined at both ends of the top mounting beam 6 corresponding to the mounting holes. The mounting top beam 6 is locked and fixed to the side connecting beam 3 by inserting the second bolt 61 into the mounting hole and threading it into the threaded hole.
[0030] Two support frames 7 are arranged at a distance from each other in a first direction between the mounting base beam 5 and the mounting top beam 6. The upper end of the support frame 7 is fixed to the mounting top beam 6, and the lower end is fixedly connected to the mounting base beam 5. These two support frames 7 serve to connect and support the mounting base beam 5 and the mounting top beam 6. Specifically, the support frame 7 has a Z-shaped structure. The two support frames 7 have mutually facing top sides and mutually opposing bottom sides. Limiting grooves 8 extending in a first direction are machined on the top surface of the mounting base beam 5 and the bottom surface of the mounting top beam 6. The first direction is the length direction of the limiting groove 8. The two ends of the limiting groove 8 in the length direction are closed. The width of the limiting groove 8 is adapted to the thickness of the support frame 7. The upper and lower ends of the support frame 7 are inserted into the corresponding limiting grooves 8 to limit the support frame 7 from the thickness direction. In the specific arrangement, the top sides of the two support frames 7 abut against each other, and the bottom sides of the two support frames 7 abut against both ends of the limiting groove 8, so as to restrict the movement of the two support frames 7 in the first direction (the length direction of the limiting groove 8). The combination of the above methods can limit the two support frames 7 in the length and width directions of the limiting groove 8, so as to prevent the support frames 7 from sliding and generating shear force on the first bolt 71, effectively protecting the first bolt 71 and effectively improving the stability of the connection of the first bolt 71.
[0031] In this embodiment, the upper end of the aforementioned support frame 7 and the mounting top beam 6, and the lower end of the support frame 7 and the mounting bottom beam 5, are locked and fixed together by first bolts 71 that are inserted vertically. Through the connection of these first bolts 71, the support frame 7, the mounting bottom beam 5, and the mounting top beam 6 are formed into an integral structure.
[0032] During assembly, the upper chord, lower chord, side connecting beam 3, bottom connecting beam 9, and diagonal support rod 4 are welded together to form the main structure of the escalator truss, and then the anti-deformation component is installed. Specifically, the anti-deformation component is assembled first. Two support frames 7 are placed opposite each other, with their top sides abutting against each other. The lower end of the support frame 7 is inserted into the limiting groove 8 on the mounting bottom beam 5, and the upper end of the support frame 7 is inserted into the limiting groove 8 on the mounting top beam 6. The support frames 7 are then connected and fixed using the first bolt 71. The assembled anti-deformation component is then placed on the bottom connecting beam 9, and the mounting top beam 6 and mounting bottom beam 5 are locked and fixed to the side connecting beam 3 using the second bolt 61 and the third bolt 51. In this way, the anti-deformation component can pull and limit the side connecting beams 3 and bottom connecting beam 9 on both sides, and the support frame 7 can pull and support the mounting top beam 6 and mounting bottom beam 5, thereby improving the assembly stability of the mounting top beam 6 and mounting bottom beam 5. The combination of the above methods can effectively enhance the deformation resistance of the escalator truss, effectively meet the usage requirements of the escalator truss, and is highly practical.

Any equivalent structural or procedural transformations made based on the content of this utility model specification, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
