[0038] Example

[0039] See Figure 1 and Figure 2 This embodiment provides a foldable transport truss device, including a main truss structure 1, a walking device 2, a support device 3, and a folding drive mechanism 4;

[0040] See Figure 1 and Figure 2 In this embodiment, the main truss structure 1 includes five truss sections: one intermediate fixed truss 1.1, two folding truss sections 1.2, and two telescopic truss sections 1.3. The two folding truss sections 1.2 are symmetrically hinged to both sides of the intermediate fixed truss 1.1. The two ends of the folding drive mechanism 4 are respectively hinged to the intermediate fixed truss 1.1 and the folding truss 1.2, used to realize the folding of the folding truss 1.2. In this embodiment, the folding drive mechanism 4 includes two sets of hydraulic cylinders, which are located on opposite sides of the intermediate fixed truss 1. The fixed end of the hydraulic cylinder is hinged to the intermediate fixed truss 1, and the telescopic end of the hydraulic cylinder is hinged to the telescopic truss 1.3. When the telescopic end of the hydraulic cylinder retracts, it drives the two sets of telescopic trusses 1.3 to rotate clockwise and fold onto opposite sides of the intermediate fixed truss 1.3. See [reference needed]. Figures 3-5 .

[0041] The two telescopic truss sections 1.3 are nested within the two folding truss sections 1.2 and can telescopically move along the folding truss sections 1.2. Specifically, the telescopic truss section 1.3 is nested within the folding truss section 1.2 via a slide rail and achieves telescopic movement through a retraction device. The slide rail is provided in multiple sets, which are arranged parallel to the length of the folding truss section 1.2 on the inner side of the folding truss section 1.2. Rollers are provided on the outer side of the telescopic truss section 1.3, and the rollers are adapted to the slide rails. By setting rollers and slide rails, the smoothness of the telescopic movement of the telescopic truss section 1.3 is improved.

The fixed end of the retraction device is mounted on the folding truss 1.2, and the telescopic end of the retraction device is connected to the telescopic truss 1.3. The retraction device extends and retracts, thereby enabling the telescopic truss 1.3 to extend and retract. Preferably, the retraction device is a hydraulic push rod or an electric lead screw.

[0043] See Figure 1 and Figure 6 The traveling device 2 is located at the bottom of the main truss structure 1 and is used to move the main truss structure 1. The traveling device 2 includes traveling wheels 2.1 and omnidirectional wheels 2.2. The traveling wheels 2.1 are located at the bottom of the intermediate fixed truss 1.1, and the omnidirectional wheels 2.2 are retractably located at the bottom of the folding truss 1.2. The omnidirectional wheels 2.2 facilitate the movement of the folding truss 1.2; the traveling wheels 2.1 facilitate the movement of the truss device during transportation, eliminating the need for a hoisting device to lift and load the truss device onto a transport vehicle.

[0044] The support device 3 is adjustablely installed at the bottom of the main truss structure 1 to support and adjust the height of the main truss structure 1. The support device 3 includes multiple adjustable legs, which are evenly distributed at the bottom of the intermediate fixed truss 1.1 and the folding truss 1.2. By setting adjustable legs, the support and height of multiple truss sections can be adjusted. During on-site installation, there is no need to manually adjust the position and level the multiple truss sections, reducing operation time, improving operation accuracy, and enhancing operation safety and efficiency.

[0045] Preferably, the adjustable outrigger is a hydraulic telescopic outrigger or an electric screw outrigger, and the bottom of the adjustable outrigger is provided with an anti-slip pad.

[0046] See Figures 5-7 The bottom end of the intermediate fixed truss 1.1 is provided with a trailer frame 5, which is used to connect with the traction device 6. During relocation, the traction device 6 pulls the entire truss device to move. In this embodiment, the traction device 6 is a tractor.

[0047] The truss device provided by this utility model is operated as follows during transportation and on-site setup:

[0048] S1, the support device 3 retracts, causing the traveling wheel 2.1 and the swivel wheel 2.2 to contact the ground;

[0049] S2, the telescopic truss 1.3 retracts and is embedded within the folding truss 1.2;

[0050] S3, the folding drive mechanism 4 operates to drive the folding truss 1.2 to rotate and fold;

[0051] S4. After the truss assembly is retracted and folded, it is connected to the tractor vehicle and the tractor vehicle pulls the truss assembly for transport.

[0052] S5. After the truss device arrives at another work location, first activate the folding drive mechanism 4 to unfold the folding truss 1.2, then extend the telescopic truss 1.3, and finally extend the adjustable legs for positioning and leveling.

[0053] The truss device provided by this utility model can be telescopically folded, solving the problem of inconvenient transportation due to its excessive length; by setting an adjustable support device, the truss device can be adjusted for multiple truss sections and leveled between trusses during on-site deployment, ensuring operational safety and improving operational efficiency; in addition, by setting a walking device, the truss device can be moved, eliminating the need for hoisting devices during transportation, thus improving transportation efficiency and reducing transportation costs.

[0054] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
