Description

Technical Field

In view of this, a multifunctional construction vehicle is disclosed in the patent document with application number 202222020355.X. The fork body in the above-mentioned prior art can only fork heavy objects and lift them upward, but cannot move the heavy objects. If the heavy objects need to be moved, the vehicle needs to be moved. However, moving the vehicle after lifting the heavy objects may cause the vehicle to roll over due to the unstable center of gravity.

[0084] 1. After raising the mast mechanism A2, the middle mast mechanism A3, and the inner mast mechanism A4, pull the pole through the winch mechanism A6 and use it when erecting the pole (e.g. Figure 19 shown).

[0085] 2. Lift the forklift telescopic arm G by forking it with the fork frame mechanism A5, and then lift it. After the steel rope A63 of the winch mechanism A6 is wound around the winch guide wheel A62 on the outer mast body A21, the inner mast body A41, and the guide wheel of the forklift telescopic arm, the steel rope A63 is pulled by the winch body A61 to lift the heavy object.

[0086] 3. After the outer mast mechanism A2, the middle mast mechanism A3, and the inner mast mechanism A4 are raised, the steel rope A63 of the winch mechanism A6 is wound around the winch guide wheel A62 on the outer mast body A21, the inner mast body A41, and the guide wheel on the cross arm in sequence, and then the steel rope A63 is pulled through the winch body A61 to lift the transformer L. Use it when lifting (such as Figure 21 shown).

[0087] 4. After lowering the outer mast mechanism A2, the middle mast mechanism A3, and the inner mast mechanism A4, use the fork frame mechanism A5 to move the cable retracting and unretracting winch H to the upper position for cable retracting and unretracting (e.g. Figure 22 shown).

[0088] 5. After the lifting platform is forked by the fork frame mechanism A5, it is raised by the outer mast mechanism A2, the middle mast mechanism A3, and the inner mast mechanism A4, thereby lifting the lifting platform I. When lifting the lifting platform I, use (such as Figure 23 shown).

[0089] 6. When the fork frame mechanism A5 is at the lowest position, the transformer L is forked by the fork frame mechanism A5, and the transformer L is lifted by the outer mast mechanism A2, the middle mast mechanism A3, and the inner mast mechanism A4, and the transformer L is moved to the top of the second-class chassis C by the moving mechanism A1. After the vehicle is parked at the designated location, the transformer L is further lifted by the outer mast mechanism A2, the middle mast mechanism A3, and the inner mast mechanism A4, and the transformer L is moved to the top of the transformer mounting crossbeam of the utility pole by the moving mechanism A1, and the transformer L is placed on the transformer mounting crossbeam of the utility pole. After the transformer is lifted, its front, back, left, right, up, down, and position can be adjusted by the fork frame side shifter so that the fixing bolt holes are aligned for easy installation (such as Figure 24 shown).

[0090] A lifting lighting lamp J is installed on the top of the cab to provide lighting for the site, and a shelf K is installed on the top of the car to place the freight elevator. The pole-mounted transformer construction special vehicle is also equipped with a monitoring system. The display screen is installed in the cab, and a camera is set on the gantry assembly A. The camera is wirelessly connected to the display screen. The working status of the gantry assembly A can be observed through the display screen. The gantry assembly A and the hydraulic support legs F can be controlled by wireless remote control or by manual control levers.

[0091] In addition, it should be noted that the shapes and names of the parts and components of the specific embodiments described in this specification may be different, and the above content described in this specification is merely an example of the structure of the utility model.
