Detailed Implementation

[0016] The present invention will be further described below with reference to embodiments and accompanying drawings:

[0017] like Figure 1-3As shown, a multi-functional hoisting vehicle mainly consists of a frame system 100, an arch frame clamping assembly 300, a rebar self-unloading assembly 200, and a folding boom crane 900. The frame system 100 is used to hold the arch frame and rebar. The frame system is equipped with the arch frame clamping assembly 300 for clamping the arch frame 320 and the folding boom crane 900 for hoisting. Several detachable stop bars 110 are spaced apart on both sides of the frame system 100, and these stop bars 110 are used to block components placed on the frame system 100 from the side. Through the combined action of the stop bars and the arch frame clamping assembly, the left and right sides of the arch frame placed on the frame system are limited. To ensure the clamping effect of the arch frame, the length of the stop bars is set according to the height of the arch frame.

[0018] Specifically, several arch frame clamping assemblies 300 are spaced apart at the front and rear. Each arch frame clamping assembly 300 includes an arch frame clamping cylinder mounted on the frame system 100. The output end of the arch frame clamping cylinder is hinged to a clamping rod 310, and the root of the clamping rod 310 is hinged to the frame system 100. When the arch frame clamping cylinder operates, it drives the clamping rod from a horizontal state to a vertical state, and cooperates with the stop rod to clamp the arch frame. When placing the arch frame, since the length of the clamping rod is fixed, the curved surfaces of the arch frame need to face each other, such as... Figure 1 and 2 As shown.

[0019] To facilitate the installation of the stop levers, mounting blocks 120 are provided on the left and right sides of the frame system 100 at the position corresponding to each stop lever 110. The upper end of the mounting block 120 is provided with a mounting groove for inserting the stop lever 110, thereby facilitating the removal of the stop lever and realizing the insertable and detachable function of the stop lever.

[0020] The frame system is also equipped with a rebar self-unloading assembly 200 for unloading rebar. The left half of the frame system 100 is used to place the arch frame 320, and the right half is used to place the rebar. Preferably, when the arch frame is not clamped, the clamping rod extends to the left and right. At this time, the right end of the clamping rod is hinged to the output end of the arch frame clamping cylinder, so that the clamping rod can clamp the arch frame located on the left half of the frame system from right to left. To prevent the arch frame on the frame system from slipping off the rear end when going uphill, a rear baffle 130 is provided at the rear end of the frame system 100 to block the rear end of the arch frame, and the width of the rear baffle 130 matches the width of the arch frame placement area.

[0021] The rebar unloading assembly 200 includes a rebar unloading cylinder mounted on the frame system 100. The output end of the rebar unloading cylinder is hinged to the unloading rod 210, and the root of the unloading rod 210 is hinged to the frame system 100. When the rebar unloading cylinder is working, it can drive the unloading rod 210 to switch between falling down and standing up. Preferably, when the unloading rod is not unloading rebar, the unloading rod extends to the left and right, with the right end of the unloading rod hinged to the right end of the frame system, and the left end of the unloading rod hinged to the output end of the rebar unloading cylinder. This allows the unloading rod to unload all the rebar located on the right side of the frame system from the right side under the action of the rebar unloading cylinder during rebar unloading.

[0022] The articulated boom crane 900 includes a rotating base 910 mounted on a frame system 100 and having a rotation function. The rotating base 910 is provided with at least two sets of mutually hinged adjustment components. Each adjustment component includes a fixed arm 920 and a folding arm 930 hinged to the fixed arm 920. An adjustment cylinder 940 is hinged to the fixed arm 920, and the output end of the adjustment cylinder 940 is hinged to the folding arm 930. The fixed arm 920 of the first adjustment component is mounted on the rotating base 910.

[0023] The last section of the adjustment assembly has a telescopic arm 950 with telescopic function on its folding arm 930.

[0024] Preferably, the system also includes a forward driving system 700, a reverse driving system 800, a hydraulic system 600, a power system 500, and front and rear axle systems 400. The forward driving system 700, hydraulic system 600, and power system 500 are all located above the front end of the frame system 100, the reverse driving system 800 is located below the rear end of the frame system 100, and the front and rear axle systems 400 are located below the frame system 100. The forward driving system 700 and the reverse driving system 800 control the output direction of the drive motor 610 in the hydraulic system 600, thereby enabling the front and rear axle systems 400 to drive forward or in reverse.

[0025] The forward driving system 700 and the reverse driving system 800 control the output direction of the drive motor 610 in the hydraulic system 600 to achieve forward or reverse driving of the front and rear axle systems 400. Specifically, a reversing valve is installed in the hydraulic system to reverse the hydraulic flow to the drive motor, thereby achieving reverse rotation of the drive motor and thus reverse driving of the vehicle. The switching of the hydraulic oil flow direction in the drive motor via a hydraulic valve is existing technology. This can be achieved by connecting a first pipe and a second pipe to two oil ports of the hydraulic motor, with reversing valves installed on the first and second pipes. When rotating forward, oil enters through the first pipe and exits through the second pipe; when rotating in reverse, oil exits through the first pipe and enters through the second pipe.

[0026] The front and rear axle system 400 includes a front axle 410 and a rear axle 420, and both the front axle 410 and the rear axle 420 are equipped with tires for moving the entire transport vehicle. The front axle 410 is connected to the output end of the transfer case 440 through the front drive shaft 430, and the rear axle 420 is connected to the output end of the transfer case 440 through the rear drive shaft 450. The input end of the transfer case 440 is connected to the drive motor 610.

[0027] At low speeds, the transfer case drives the front and rear drive shafts synchronously, driving the front and rear axles respectively, which in turn rotates the tires, putting the entire transport vehicle in four-wheel drive mode. This provides significant driving force when climbing hills or traversing muddy roads, ensuring stability. At high speeds, the front drive can disengage, and the transfer case only drives the rear drive shaft, driving the rear wheels via the rear axle. This is rear-wheel drive mode, effectively reducing fuel consumption and improving fuel economy.

[0028] The power system uses a diesel engine, and the hydraulic system contains multiple hydraulic cylinders, including at least an oil pump that provides hydraulic power to the drive motor and a gear pump that provides power for steering, unloading rebar, and clamping the arch frame. The main body of the chassis system is welded from manganese steel rectangular tubing, and the platform consists entirely of anti-slip patterned plates. The reverse driving system is a simple cab, only used for driving the vehicle out of the tunnel after unloading materials; after exiting the tunnel, it should switch to forward driving.
