Abstract
Description
Technical Field
[0001] This utility model relates to support equipment for transporting escalator trusses, and in particular to an escalator truss stacking and fixing device. Background Technology
[0002] Escalators are indispensable in major public shopping malls, and escalator trusses are a crucial component of escalators. Due to the large span and inclined angle of escalator metal trusses, they occupy a significant amount of space. Furthermore, the upper chord of the truss typically has glass fixing plates or other interface parts, preventing the direct stacking of more than two trusses during transportation. Therefore, a flatbed truck can only carry two or two sections of metal trusses, resulting in high transportation costs. To reduce these costs, devices for supporting metal trusses during transportation have emerged. For example, CN214190943U discloses a support structure for transporting escalator trusses, which ensures the stable stacking of upper and lower trusses during transportation, preventing slippage and displacement. However, this structure requires reinforcement to ensure the connection strength between the support body and the connecting crossbars, resulting in a complex structure, high production costs, and a heavy support, making it difficult to meet market demands. Utility Model Content
[0003] Therefore, the purpose of this utility model is to provide an escalator truss stacking and fixing device, which has the advantages of simple structure and high structural strength.
[0004] An escalator truss stacking and fixing device includes a connecting rod and a support body disposed at both ends of the connecting rod. The support body includes two connecting members and two supporting members. The connecting members are symmetrically fixed on both sides of the connecting rod and in contact with the side wall surface of the connecting rod. The supporting members are respectively disposed at both ends of the connecting members in the extension direction for connecting to the truss.
[0005] The escalator truss stacking and fixing device described in this utility model has a simpler structure. By adjusting the connection method between the main body of the support and the connecting rod, its connection strength is improved, thus eliminating the need for additional reinforcing ribs, clamps, and other structures, thereby reducing manufacturing costs.
[0006] Furthermore, the connector includes a clamping part and a supporting part connected in an L-shape. The clamping part is attached to the connecting rod and fixedly connected by welding. The supporting part is located on the side of the clamping part near the other connector. Its structure is simple and can ensure the structural support strength.
[0007] Furthermore, the extension direction of the connector is perpendicular to the axial direction of the connecting rod, and the connecting rod is connected to the middle of the connector. This structure makes the truss stacking position stable and ensures the support strength of the bracket.
[0008] Furthermore, the connector is made of angle steel, which has a simple structure and reduces the cost of the bracket.
[0009] Furthermore, the support member includes a connecting portion and a bent portion, which are arranged in an L-shape. The connecting portion is fixed to the connecting member by welding, and the bent portion is located on the side of the connecting portion away from the other connecting member and extends away from the connecting rod. This structure further enables the stable stacking of trusses.
[0010] Furthermore, the bent portion is provided with a mounting hole, which may be one or two symmetrically arranged on both sides of the axis of the connecting rod, thereby ensuring a stable connection between the support and the truss.
[0011] Furthermore, the support members are symmetrically arranged at both ends of the connector, allowing the bracket to be used in both directions to adapt to different scenario requirements.
[0012] Furthermore, the connecting rod includes a locking member, a first rod body, and a second rod body. The first and second rod bodies are interlocked along their axial direction. The first rod body is connected to one of the bracket bodies, and the second rod body is connected to another bracket body. Both the first and second rod bodies have multiple fixing holes along their axial direction, and the locking member passes through these fixing holes to restrict the relative sliding of the first and second rod bodies. This structure allows for adjustment of the bracket distance, thus accommodating trusses of different sizes.
[0013] Furthermore, the first and second rods are square rods, which have a simple structure and a certain strength. At the same time, relative rotation is avoided during the sliding adjustment process, which facilitates the locking components to fix the rods and ensures the stacking stability of the trusses.
[0014] Furthermore, the locking element is a fastening screw, which is easy to disassemble and assemble, and enables quick adjustment of the connecting rod.
[0015] To better understand and implement this invention, the following detailed description is provided in conjunction with the accompanying drawings. Attached Figure Description

Detailed Implementation
[0022] Please see Figure 1-4 , Figure 1 This is an axial view of the truss stacking support described in this utility model; Figure 2 This is a front view of the truss stacking support described in this utility model; Figure 3 This is a top view of the truss stacking support described in this utility model; Figure 4 This is a left view of the truss stacking support described in this utility model.
[0023] This utility model discloses an escalator truss stacking and fixing device, including a connecting rod 1 and a support body 2 disposed at both ends of the connecting rod 1. The support body 2 is used to clamp and connect with the truss, and the connecting rod 1 plays a supporting role between the support bodies 2, thereby realizing the stacking and transportation of the escalator truss.
[0024] The connecting rod 1 can have various cross-sectional shapes, but a square cross-section is preferred to ensure connection strength. The connecting rod 1 can be a single rod of fixed length. To accommodate different specifications of escalator trusses, in this embodiment, the connecting rod 1 is configured as a telescopically adjustable structure. The connecting rod 1 includes a locking member 11, a first rod 12, and a second rod 13. The left end of the first rod 12 is connected to the support body 2 located at the left end of the connecting rod 1, and the right end of the second rod 13 is connected to the support body 2 located at the right end of the connecting rod 1. The right end of the first rod 12 and the left end of the second rod 13 are interlocked along the axial direction (i.e., the transverse direction shown in the figure), allowing the first rod 12 and the second rod 13 to slide relative to each other, thus adjusting the overall length of the connecting rod 1. The first rod 12 and the second rod 13 are preferably square rods, thereby ensuring the connection strength between the connecting rod 1 and the support body 2 while preventing relative rotation of the first rod 12 and the second rod 13 during adjustment.
[0025] The locking element 11 can be a pin or similar structure, but in this embodiment, it is preferably a fastening screw. Multiple fixing holes 14 are provided along the axis on both the first rod 12 and the second rod 13. The fastening screw passes through the fixing holes 14, thereby restricting the relative sliding of the first rod 12 and the second rod 13, locking the total length of the first rod 12 and the second rod 13, and ensuring the support effect.
[0026] Each bracket body 2 includes two connectors 21 and two support members 22. The connectors 21 are symmetrically fixed to both sides of the connecting rod 1, and their extension direction is perpendicular to the axis of the connecting rod 1 (i.e., the up-down direction shown in the figure). To allow the bracket to be installed in both forward and reverse directions, the support members 22 are symmetrically arranged at both ends of the extension direction of the connectors 21. The connector 21 includes a clamping part 211 and a support part 212 connected in an L-shape. The clamping part 211 is attached to the connecting rod 1 and fixedly connected by welding, so that the connector 21 contacts the side wall surface of the connecting rod 1. The connecting rod 1 is located in the middle of the clamping part 211 to ensure support strength. The support part 212 is located on the side of the clamping part 211 closer to the other connector 21. The connectors 21 can be made of bent sheet metal, preferably angle steel, thereby reducing production costs.
[0027] The support member 22 includes a connecting portion 221 and a bent portion 222, which are L-shaped. The connecting portion 221 is fixed to the connecting member 21 by welding and is used to abut against the truss to support it. The bent portion 222 is located on the side of the connecting portion 221 away from the other connecting member 21 and extends away from the connecting rod 1 to limit the truss. Since the support members 22 are symmetrically arranged, the extension lengths of the bent portions 222 of the support members 22 at the upper and lower ends are equal. The bent portion 222 is provided with mounting holes 223. As shown in the figure, there can be one mounting hole 223, preferably two, symmetrically opened on both sides of the axis of the connecting rod 1. Bolts, nails, pins, and other structures can be inserted inside to achieve a fixed connection between the upper or lower truss and the support member 22, thereby improving stability.
[0028] Please see Figure 5 , Figure 5 This is a schematic diagram illustrating the use of the truss stacking support described in this utility model. In use, one or more supports can be selected for support according to the truss specifications. First, remove the locking piece 11 and adjust the relative positions of the first rod 12 and the second rod 13 so that the total length of the connecting rod 1 matches the stacking height of the escalator truss. Next, insert the locking piece 11 into the fixing hole 14 to lock the relative positions of the first rod 12 and the second rod 13, thus fixing the positions of the two support bodies 2. At this point, the upper support member 22 clamps the upper truss 3, and the lower support member 22 clamps the lower truss 4, allowing the upper truss 3 and lower truss 4 to be stacked. During transportation, the connecting rod 1 supports the support body 2, thereby stabilizing the positions of the upper truss 3 and lower truss 4 and preventing the truss from falling off.
[0029] The escalator truss stacking and fixing device described in this utility model has a simpler structure. By adjusting the connection method between the main body of the support and the connecting rod, its connection strength is improved, thus eliminating the need for additional reinforcing ribs, clamps, and other structures, thereby reducing manufacturing costs. Furthermore, the telescopic connecting rod allows the support to be adapted to various sizes of escalator trusses, and the symmetrically arranged support members allow for forward or reverse installation, making the support more flexible in use.
