Description

Technical Field

[0001] This utility model relates to the field of escalators or moving walkways, specifically a truss support. Background Technology

[0002] When escalators or moving walkways have a large lifting height, they are often produced and transported in sections. Due to size limitations of transport equipment (e.g., containers), multiple escalator or moving walkway trusses need to be stacked to improve transport efficiency and container utilization. For example, Chinese Patent CN107857186B describes a truss support for fixing a first truss and a second truss stacked on top of the first truss. The truss support includes an upper pressing member for pressing against the second truss, a connecting member for supporting the second truss and pressing against the first truss, and a support member for supporting the first truss. The upper pressing member and the support member are respectively fixedly connected to the connecting member by fastening components. One or more of the connectors and the support members are provided with side stops, which are used to limit the position of the first truss and the second truss in the width direction. The truss support provided by the present invention has fewer parts, is easy to install, and can stack and transport disassembled escalators or moving walkways, saving transportation costs. The number of units used and the height of use can be adjusted according to actual needs, and it has strong versatility. The above patent can use a special connecting component to connect and fix the upper and lower trusses to achieve effective stacking. However, when stacking the upper and lower trusses, due to the limitation of transportation space, it is not possible to adjust the stacking gap of the upper and lower trusses according to the optimal use scenario, which can easily cause the gap to be too small and fail to guarantee the safe stacking gap of the two trusses. Therefore, we propose a truss support. Utility Model Content

[0023] 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.

[0024] Please see Figure 1-5 A truss support includes truss components connected by a connecting component 4. The truss components include multiple sets of vertical bars 1, multiple sets of horizontal bars 2, and multiple strip bars 3. The upper and lower ends of the multiple vertical bars 1 on the same side are connected by the strip bars 3, and the corresponding vertical bars 1 on both sides are connected by the horizontal bars 2. The connecting component 4 includes a telescopic component and a snap-fit ​​component. Snap-fit ​​components are snapped onto the strip bars 3 on the corresponding side of the upper and lower truss components. The upper and lower corresponding snap-fit ​​components are connected by a telescopic component. By adding a telescopic component, the connection spacing between the upper and lower truss components can be adjusted according to requirements.

[0025] Furthermore, the snap-fit ​​assembly includes a top plate 9 and an L-shaped block 12. A protrusion 10 is integrally formed on the top plate 9. The top plate 9 and the L-shaped block 12 are located on the upper and lower sides of the strip rod 3, respectively. The protrusion 10 fits into the L-shaped block 12. Threaded holes are provided on both the L-shaped block 12 and the protrusion 10. The L-shaped block 12 and the protrusion 10 are threaded together.

[0026] Furthermore, a second protrusion 11 is integrally formed on the inner side of the top plate 9 corresponding to the strip rod 3. The strip rod 3 is located in the gap between the L-shaped block 12 and the second protrusion 11. A bent protrusion 13 is integrally formed at the end of the L-shaped block 12. The other side of the strip rod 3 is located between the bent protrusion 13 and the bent area of ​​the L-shaped block 12. During installation, the L-shaped block 12 is placed on the strip rod 3, and then the gap between the second protrusion 11 and the L-shaped block 12 is aligned with the strip rod 3 and snapped in. Then, the position is adjusted so that the first protrusion 10 corresponds to the threaded hole on the L-shaped block 12. Then, the L-shaped block 12 and the first protrusion 10 are threaded together using a bolt 14 to achieve the connection between the two.

[0027] Furthermore, a middle fixing plate 5 is fixedly connected between the upper and lower telescopic components. Both the upper and lower sides of the middle fixing plate 5 are integrally formed with inserts 8. The cross-section of the inserts 8 is rectangular, and the inserts 8 are fixedly connected to the telescopic components.

[0028] Furthermore, the side of the insert 8 is integrally formed with a reinforcing rib 7 on the plane corresponding to the middle fixing plate 5. By adding the reinforcing rib 7, the overall strength of the connecting component 4 can be increased.

[0029] Furthermore, the telescopic component includes a square sleeve 6 with a U-shaped cross-section. An insert 8 is inserted into the inner side of the square sleeve 6. Multiple sets of circular holes 15 and 17 are equally spaced on the insert 8. The inner wall of the circular holes 17 is provided with internal threads. Circular holes 15 and 17 that coincide in position are threadedly connected to circular holes 15. When it is necessary to adjust the position between the upper and lower truss components, the vertical height of the upper and lower truss components is adjusted. At this time, the insertion distance of the insert 8 inside the square sleeve 6 changes. After the position adjustment is completed, at least two circular holes 17 correspond to one circular hole 15. Then, a bolt 2 16 is passed through the circular hole 15 and threadedly connected to the circular hole 17 to achieve telescopic adjustment and change the distance between the upper and lower truss components.

[0030] Furthermore, there are at least two circular holes 15. Therefore, when adjusting the spacing between the upper and lower truss components, it is necessary to maintain the corresponding positions of at least two circular holes 15 and two circular holes 17. Thus, two bolts 16 are required for connection, which can increase the connection strength and stability.

[0031] Working principle: When two truss components need to be stacked, one truss component is lifted using hoisting equipment and moved above the other truss component. Then, the L-shaped block 12 is placed on the opposite side of the strip rod 3 in the upper and lower truss components and engaged. Next, the gap between the second protrusion 11 and the L-shaped block 12 is aligned with the strip rod 3 and engaged. The position is then adjusted so that the first protrusion 10 aligns with the threaded hole on the L-shaped block 12. Finally, bolt 14 is used to thread the L-shaped block 12 and the first protrusion 10 together, achieving the connection. Adjustments are then made according to placement and transportation requirements. The spacing between the upper and lower truss components is adjusted to change the vertical height of the upper and lower truss components. At this time, the insertion distance of the insert 8 inside the square sleeve 6 changes. After the position is adjusted, ensure that at least two circular holes 17 correspond to one circular hole 15. Then, use bolt 16 to pass through circular hole 15 and thread it together with circular hole 17 to achieve telescopic adjustment. At the same time, when using this device, the number and position of the connecting components 4 can be increased according to the different lengths or weights of the truss components, making it more flexible to use.

[0032] 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.
