A construction platform lifting ring 3-2-5 is provided at the end of the first lifting wire 3-2-3. The construction platform lifting ring 3-2-5 is used to connect with the construction platform 4. When the construction platform lifting motor 3-2-1 is working, it drives the first winch 3-2-2 to rotate and then reel in or release the first lifting wire 3-2-3. The first lifting wire 3-2-3 passes through the first pulley block 3-2-4 to lift and lower the construction platform 4.

[0045] The counterweight lifting assembly 3-3 includes a counterweight lifting motor 3-3-1 disposed on the vehicle body plate 1-1-1, a second winch 3-3-2 is disposed at the output end of the counterweight lifting motor 3-3-1, a coiled second lifting wire 3-3-3 is disposed on the second winch 3-3-2, the second lifting wire 3-3-3 is slidably connected to a plurality of second pulley blocks 3-3-4, and a reserved pulley mounting hole is disposed on the crossbeam 3-1-1 to facilitate the second pulley blocks 3-3-4 to move the second pulley blocks 3-3-4.

In this embodiment, the first pulley block 3-2-4 and the second pulley block 3-3-4 are both fixed pulley assemblies.

[0046] like Figure 5As shown, the construction platform lifting motor 3-2-1 and the counterweight lifting motor 3-3-1 are both arranged on the motor seat 3-4, and the motor seat 3-4 is fixedly connected to the vehicle body plate 1-1-1 by a bolt assembly, and a winch frame 3-4-1 is arranged on the motor seat 3-4, and the first winch 3-2-2 and the second winch 3-3-2 are rotatably connected to the winch frame 3-4-1 respectively, and at the same time, the winch frame 3-4-1 is provided with reserved holes for the first lifting wire 3-2-3 and the second lifting wire 3-3-3 to pass through.

[0047] like Figures 6 to 8 As shown, the construction platform 4 includes a workbench 4-1, and lifting slide bars 4-2 are provided at both ends of the workbench 4-1. The lifting slide bars 4-2 are slidably connected to the lifting slideway 4-3. The lifting slideway 4-3 is fixedly connected to one end of the crossbeam 3-1-1, and the lifting slideway 4-3 is arranged perpendicular to the crossbeam 3-1-1. A protective guardrail 4-4 is provided around the workbench 4-1, and the protective guardrail 4-4 is used to protect the safety of construction personnel. A reinforcing rod is fixedly connected to the protective guardrail 4-4, and a lifting lug 4-5 is fixedly connected to the reinforcing rod, and the lifting lug 4-5 is connected to the construction platform lifting ring 3-2-5. When the construction platform lifting motor 3-2-1 is working, it drives the first lifting wire 3-2-3 and the construction platform lifting ring 3-2-5 to rise and fall, and the lifting slide bar 4-2 slides in the lifting slideway 4-3. At the same time, the lifting slideway 4-3 plays a guiding role, thereby driving the workbench 4-1 to rise and fall.

[0048] In this embodiment, a reinforcing guardrail 4-2-2 is fixedly provided on the lifting slide bar 4-2 to ensure the stability of the lifting slide bar 4-2; a limiting plate 4-2-1 is provided on the top of the lifting slide bar 4-2 to prevent the lifting slide bar 4-2 from escaping from the lifting slideway 4-3 when descending.

[0049] like Fig. 9 As shown, the counterweight unit 5 includes a counterweight box 5-1, a discharging bottom cover 5-2 with a switch handle is arranged at the bottom of the counterweight box 5-1, and a charging top cover 5-3 is arranged at the top of the counterweight box 5-1. The charging top cover 5-3 can be opened to put the counterweight material in to add weight to the counterweight box 5-1, and the handle of the discharging bottom cover 5-2 can be opened to discharge the counterweight material from the bottom of the counterweight box 5-1.

[0050] Safety limit ropes 5-4 and lifting seats 5-5 are provided on both sides of the counterweight box 5-1, and the lifting seats 5-5 are connected to the counterweight lifting rings 3-3-5. When the counterweight lifting motor 3-3-1 is working, it drives the second lifting wire 3-3-3 and the counterweight lifting ring 3-3-5 to move up and down, thereby driving the counterweight box 5-1 to move up and down. Since the counterweight box 5-1 only needs to leave one end of the ground to provide the counterweight function for the entire device, there is no need to set a guide mechanism for guidance.

[0051] One end of the safety limit rope 5-4 is detachably mounted on the counterweight box 5-1, and the other end of the safety limit rope 5-4 is detachably mounted on the crossbeam 3-1-1. The safety limit rope 5-4 is used to prevent the counterweight box 5-1 from being accidentally unhooked when it is lifted.

[0052] like Figures 1 to 9 As shown, the use process of the present invention is as follows:

[0053] First, transport the device to the working position and assemble the device. After the assembly is completed, place an appropriate amount of counterweight material in the counterweight box 5-1, lock the unloading bottom cover 5-2 and the loading top cover 5-3, connect the construction platform lifting ring 3-2-5 to the lifting lug 4-5, connect the counterweight lifting ring 3-3-5 to the lifting seat 5-5, and the operator stands on the standing platform 2-2 to operate the intelligent control unit 2-1 to control the counterweight lifting motor 3-3-1 to work and lift the counterweight box 5-1. The construction worker stands on the workbench 4-1 and holds the protective guardrail 4-4. The operator controls the construction platform lifting motor 3-2-1 to lift the workbench 4-1 to the required height. After the lifting is completed without shaking, the construction worker performs the construction work, and the workbench 4-1 can be raised and lowered at any time according to the construction work requirements. During the construction work, the cutting fluid storage tank 1-2 is used as a storage device for the cutting fluid required in the construction work, ensuring the efficiency and safety of the construction work.

[0054] Since a construction site usually operates along the same line for tens to hundreds of meters, and the distance between adjacent drilling operation points is within 2 meters, after the single-point construction operation is completed, the operator controls the driving vehicle 1-1 to smoothly run to the adjacent operation point to continue the construction, eliminating the need for repeated up and down movement of personnel and equipment at different operation points, saving overall operation time. After the operation is completed, if long-distance transportation or storage is required, the various units of the device can be disassembled and transported, which improves the transportation efficiency and reduces the storage space occupied.

[0055] The embodiments described above are only descriptions of the preferred modes of the present invention, and are not intended to limit the scope of the present invention. Without departing from the design spirit of the present invention, various modifications and improvements made to the technical solutions of the present invention by ordinary technicians in this field should all fall within the protection scope determined by the claims of the present invention.
