Description

Technical Field

[0001] This invention relates to the field of truss auxiliary installation device technology, and specifically to a truss assembly device. Background Technology

[0002] Trusses are widely used as an important load-bearing structure in fields such as building construction, stage construction, and large equipment installation. Trusses are usually composed of multiple members connected by nodes, and the quality of their assembly directly affects the stability and safety of the overall structure.

[0003] Currently, truss assembly faces challenges due to difficulties in connection and alignment. Because of their large size and weight, manual handling and pulling methods make it difficult to precisely control the relative positions of trusses, often resulting in misalignment or displacement at the truss ends, increasing connection complexity. Furthermore, the alignment problem is even more pronounced in traditional hoisting installation: after assembly, trusses often require hoisting as a whole or in sections to connect to pre-designated installation locations at higher elevations. However, during hoisting, trusses are susceptible to swaying or shifting due to gravity, wind, and other factors. Operators struggle to adjust the truss's posture in real time, making it difficult to guarantee alignment accuracy between the truss and the installation reference. This leads to low hoisting efficiency and increased construction costs.

[0004] Therefore, in view of the problem of inconvenient alignment in the existing truss assembly process, we consider designing an auxiliary device that can efficiently align trusses to improve the efficiency and quality of truss assembly. In view of this, we propose a truss assembly device. Summary of the Invention

[0018] The technical solutions of the present invention will be clearly and completely described below with reference to the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. Unless otherwise specified, the embodiments and features in the embodiments of this application can be combined with each other. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0019] Please see Figure 1-11 The present invention will describe the above technical solution in detail through the following embodiments: In this embodiment, the truss assembly device, such as Figure 1 and Figure 2 The structure shown requires this device to lift the horizontal truss 8 to the installation position of the two vertical trusses 7 on both sides, achieving alignment of the installation points and thus enabling efficient and accurate truss assembly operations. This includes a scissor lift 1 with a platform 101 mounted on top, a double-headed telescopic cylinder 3 mounted on the platform 101, and also includes: Two intermediate trays 2, as Figure 3 , Figure 4 As shown in the structure, in order to achieve the effect of moving to both sides and being clamped on the two vertical trusses 7, this embodiment needs to realize the telescopic action. Therefore, in this embodiment, friction-reducing rollers 4 for supporting the intermediate support plate 2 are rotatably installed on both sides of the platform 101. The output shaft of the double-headed telescopic cylinder 3, which is fixedly installed on the platform 101, is connected to the intermediate support plate 2. The intermediate support plate 2 is moved synchronously through the double-headed telescopic cylinder 3.

[0020] like Figures 3-5 The structure shown includes two positioning parts, each comprising an adjustment assembly 5 mounted on the intermediate support plate 2, and a limiting assembly 6 detachably mounted on the adjustment assembly 5. Specifically, in this embodiment, the adjustment assembly 5 includes a connecting plate 52 mounted on the intermediate support plate 2, and side fixing brackets 51 symmetrically mounted at both ends of the connecting plate 52. Figure 6 , Figure 7The structure shown has a guide rail 58 horizontally mounted inside the side fixing frame 51. A side plate 54 is slidably mounted on the guide rail 58 via a slider 59. A movable crossbar 53 is detachably mounted between the two side plates 54. A rack and pinion plate 57 parallel to the guide rail 58 is mounted inside one side fixing frame 51. A drive motor 55 mounted on the side plate 54 provides driving power. A gear 56 that meshes with the rack and pinion plate 57 is mounted at the output shaft of the drive motor 55. When the motor rotates, the limiting assembly 6 moves along the side fixing frame 51.

[0021] Considering that the lifting range of the scissor lift 1 is large, it is impossible to accurately position and lift the horizontal truss 8 to the installation height in one step. Therefore, in this embodiment, a lifting cylinder 511 with a vertically set output shaft and a lifting bracket 510 with a vertically slidable installation are fixedly installed on the movable crossbeam 53. The output shaft of the lifting cylinder 511 is fixedly connected to the lifting bracket 510, and the limiting component 6 is detachably installed on the lifting bracket 510 through the U-shaped bracket 61.

[0022] like Figures 8-11 As shown in the structure, the U-shaped bracket 61 has a support cavity for supporting the horizontal truss 8 and inserting it into the vertical truss 7. In this embodiment, a limiting cavity with a guiding arrangement is provided on the vertical cavity wall of the support cavity, and a limiting unit 63 is rotatably installed in the limiting cavity. Specifically, the limiting cavity includes a first groove 6101, a deflection cavity 6103, and a second groove 6102 that are guided from the inside to the outside on the vertical cavity wall of the support cavity. The limiting unit 63 includes a stop block 633 and a locking block 634 that are fixedly connected by a connecting rod 632. A rotating shaft 631 is fixedly connected to the connecting rod 632. It should be noted that in this embodiment, the stop block 633 and the locking block 634 are rotatably installed in the first groove 6101 and the second groove 6102 respectively through the rotating shaft 631. In order to obtain the reset function, a spring for pushing the stop block 633 outward is installed in the first groove 6101.

[0023] That is, when there is no external force, when the abutment 633 is pushed out under the action of the spring, the locking block 634 is embedded in the second groove 6102; when the two side limiting units 63 are moved to insert and squeeze the two side vertical trusses 7, the vertical truss 7 frame will press the abutment 633 into the first groove 6101 after it is pressed, and at this time the locking block 634 is pushed out along the second groove 6102; in order to accurately achieve positioning through the lifting cylinder 511, a distance measuring sensor is installed on the locking block 634, that is, when the locking block 634 is pushed out, there is a corresponding surface with the vertical truss 7. The predetermined position is determined by lifting and lowering to a predetermined distance. Finally, after the installation is completed, the limiting unit 63 is horizontally retracted and released.

[0024] During the alignment and retraction processes, considering the potential for movement due to friction with the vertical truss 7, this embodiment, for example... Figure 10 , Figure 11The structure shown has a friction-reducing roller 635 rotatably mounted on the abutment block 633 via a rotating cavity 6331. Specifically, in this embodiment, the friction-reducing roller 635 includes two symmetrically arranged cylindrical end blocks 6351 and a four-layer cylindrical intermediate block 6352 detachably mounted between the two cylindrical end blocks 6351 via a fastening screw 6354. A convex shaft block 6301 is provided at the axis of the cylindrical end block 6351. In this embodiment, ball bearings 6353 are rotatably mounted between adjacent cylindrical intermediate blocks 6352 and between cylindrical end blocks 6351 and cylindrical intermediate blocks 6352. The ball bearings 6353 are in communication with the roller surface of the friction-reducing roller 635, so that they can contact the vertical truss 7 and transform into rolling friction. At the same time, in order to better center the horizontal truss 8 during the alignment of the vertical truss 7, a rolling roller 62 is rotatably mounted in the support cavity at the horizontal plane of the U-shaped bracket 61. The rolling roller 62 is perpendicular to the horizontal truss 8.

[0025] It should be noted that if the embodiments of the present invention involve directional indicators (such as up, down, left, right, front, back, etc.), the directional indicators are only used to explain the relative positional relationship and movement of the components in a specific posture. If the specific posture changes, the directional indicators will also change accordingly.

[0026] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the invention can be implemented in other specific forms without departing from the spirit or essential characteristics of the invention. Therefore, the embodiments should be considered in all respects as exemplary and non-limiting, and the scope of the invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within the present invention.
