[0046] The multifunctional drilling and lifting vehicle integrates drilling and lifting functions to meet different operation requirements; the variable-length oil cylinder 8 drives the telescopic arm 3 to rotate to adjust the drilling depth of the spiral anchor assembly to adapt to different drilling requirements; the spiral anchor assembly is arranged in the middle position of the telescopic arm 3, with a reasonable layout and easy operation.

[0047] Below, the multifunctional drilling and crane integrated working vehicle in the present invention is described by taking the working vehicle chassis 1 as a tractor chassis as an example. Of course, the working vehicle chassis 1 can also be other vehicle chassis with corresponding functions, and the present invention is not limited thereto.

[0048] The multifunctional drilling and crane integrated working vehicle further includes: a sub-frame 15; the sub-frame 15 is fixedly mounted at the bottom of the working vehicle chassis 1; the base arm 2 is fixedly mounted at the top of one end of the sub-frame 15 located at the rear of the working vehicle chassis 1 through a slewing bearing 10; the control component is electrically connected to the arm rotation motor 16 at the bottom of the slewing bearing 10, and controls the arm rotation motor 16 to drive the base arm 2 to rotate in the horizontal direction.

The subframe 15 is fixedly arranged at the bottom of the operation vehicle chassis 1, and the length of the subframe 15 is greater than the length of the operation vehicle chassis 1, thereby enhancing the structural stability and providing a larger space for the horizontal rotation of the base arm 2, thereby improving the operation flexibility and precision, and facilitating modification and upgrading to adapt to different operation requirements, thereby further improving the performance and reliability of the operation vehicle.

[0050] Specifically, the subframe 15 is fixed to the bottom of the working vehicle chassis 1 by bolt connection and welding, and is made of high-strength structural steel as a whole, which greatly improves the frame strength. The subframe 15 runs through the bottom of the working vehicle chassis 1 as a whole, and its total length is greater than the length of the working vehicle chassis 1.

[0051] The base arm 2 is fixedly connected to the outer ring of the slewing bearing 10 by bolts, and the inner ring of the slewing bearing 10 is fixedly connected to the rear end of the subframe 15. The slewing bearing 10 provides rotational power to the base arm 2 through the boom rotation motor 16, thereby driving the base arm 2 to perform a rotational motion.

[0057] Furthermore, the hydraulic motor 5 is rotationally connected to the telescopic arm 3; in the working state, the control component drives the spiral anchor 4 to rotate in the vertical direction through the hydraulic motor 5, so that the working end of the spiral anchor 4 is vertically downward; in the non-working state, the control component drives the spiral anchor 4 to rotate in the vertical direction through the hydraulic motor 5, so that the axial direction of the spiral anchor 4 is consistent with the axial direction of the telescopic arm 3.

[0063] The present invention is further described below with reference to several usage scenarios of a multifunctional drilling and crane integrated operation vehicle:

[0064] Scenario 1: Operation method of outdoor pole hoisting

[0065] When carrying out pole hoisting operations, it is necessary to carry out a pressure resistance test on the multifunctional drilling and hoisting station vehicle position and the road surface on the driving path. If the pressure resistance test does not meet the standards, the road surface needs to be excavated, backfilled or compacted until the ground hardness meets the mobile crane operation standards.

[0066] First, activate the one-button leveling device button of the legs, so that the rear support legs 9, the rear H-shaped legs 12 and the front H-shaped legs 14 of the vehicle are extended horizontally and stably supported on the ground. If necessary, the legs need to be reinforced. Then prepare for the lifting of the pole. First, put the lifting clamp on the cement pole and fix it. The position of the clamp should be close to the small end of the cement pole, and the distance from the small end of the cement pole is 1 / 3 of the total length of the pole. Control the slewing bearing 10 to rotate, and adjust the position of the telescopic arm 3 so that the hook 7 is directly above the clamp of the cement pole. Let the hook 7 slowly fall to the ground, connect the hook 7 to the clamp of the cement pole, and use a binding belt for auxiliary fixing. After the pole and the hook 7 are firmly fixed, slowly raise the hook 7 to lift the cement pole off the ground. The slewing bearing 10, the base arm 2 and the telescopic arm 3 are operated to rotate until the pole is hoisted to the predetermined position, the pole is slowly dropped and dumped to the ground, and finally the pole fixing device is removed. At this point, a pole hoisting operation is completed.

[0067] Scenario 2: Outdoor foundation pit excavation and pole erection operations

[0068] Before excavating the foundation pit and erecting the electric poles, the ground at the station location must be tested for pressure resistance. If the pressure resistance test does not meet the standards, the road surface must be excavated, backfilled or compacted until the ground hardness meets the mobile crane operation standards.

[0069] First, start the one-touch leveling device button of the outriggers, so that the rear support legs 9, the rear H-shaped legs 12 and the front H-shaped legs 14 of the vehicle are extended horizontally and stably supported on the ground. If necessary, the legs need to be reinforced. Before excavating the foundation pit, the telescopic arm 3 must be adjusted to a suitable position, and the spiral anchor 4 must be dropped so that its head is in contact with the ground and the spiral anchor 4 forms a 90° angle with the ground as a whole. Start the operation button to rotate the spiral anchor 4 clockwise, and at the same time adjust the elevation angle of the telescopic arm 3 so that it drives the spiral anchor 4 to gradually descend, thereby completing the excavation of the foundation pit. If the excavation site is in a mountainous area, the spiral anchor 4 can be replaced with a harder impact spiral anchor 4 to complete the geological groundbreaking and stone-breaking operations in mountainous areas.

[0070] After the excavation of the foundation pit is completed, the spiral anchor 4 is returned to its position so that it is parallel to the telescopic arm 3 and fixed. Then, the pole is prepared for lifting. The lifting clamp is put on the cement pole and fixed. The clamp position should be close to the small end of the cement pole, and the distance from the small end of the cement pole is 1 / 3 of the total length of the pole. Control the slewing bearing 10 to rotate, adjust the position of the telescopic arm 3, so that the hook 7 is directly above the clamp of the cement pole. Let the hook 7 slowly fall to the ground, connect the hook 7 with the clamp of the cement pole, and use the binding belt for auxiliary fixation. After the pole and the hook 7 are firmly fixed, slowly raise the hook 7 and lift the cement pole off the ground. Operate the slewing bearing 10, the base arm 2 and the telescopic arm 3 to rotate until the pole is lifted above the foundation pit, slowly drop the pole until the large end of the cement pole is completely placed in the foundation pit, complete the backfilling and compaction of the foundation pit, and finally remove the fixing device. At this point, the pole erection operation of the foundation pit excavator is completed.

[0071] The embodiment of the present invention is intended to protect a multifunctional drilling and lifting work vehicle, including: a work vehicle chassis, a base arm assembly, a telescopic arm, a luffing cylinder, a spiral anchor assembly, a hook and a control assembly; the bottom of the base arm assembly is connected to the work vehicle chassis for rotation in the horizontal direction, and the top of the base arm assembly is connected to the telescopic arm for rotation in the vertical direction; the luffing cylinder is telescopically connected to one end of the telescopic arm close to the base arm assembly, driving the telescopic arm to reciprocate in the vertical direction with its connection end with the base arm assembly as the center; the spiral anchor assembly is arranged in the middle position of the telescopic arm, and the drilling depth of the spiral anchor assembly is adjusted when the telescopic arm rotates in the vertical direction; the hook is fixed to the bottom of one end of the telescopic arm away from the base arm assembly; the control assembly is electrically connected to the luffing cylinder and the base arm assembly respectively, controls the base arm assembly to rotate in the horizontal direction, and controls the top of the luffing cylinder to reciprocate in the vertical direction. The above technical scheme has the following effects:

[0072] 1. Integrate drilling and lifting functions into one, reducing the time and cost of switching equipment between different tasks;

[0073] 2. The driving effect of the luffing cylinder on the telescopic arm allows the work vehicle to accurately adjust the drilling depth of the spiral anchor assembly and the height of the hook in the vertical direction. Whether it is drilling at different depths or lifting objects at different heights, precise operation can be achieved to meet various complex operation requirements;

[0074] 3. The spiral anchor assembly is set in the middle position of the telescopic arm, which makes the work vehicle more stable during drilling operations. The spiral anchor assembly will generate downward pressure and torque when working. Setting it in the middle position of the telescopic arm can better balance these forces, reduce the shaking and deformation of the telescopic arm, and improve the accuracy and stability of drilling.
