Description

Technical Field

[0001] The present invention relates to the technical field of coal mine hydraulic fracturing roof control equipment, and in particular to a hydraulic fracturing safe and efficient operation robot. Background Art

[0002] Hydraulic fracturing, as an economical, safe, and efficient technology for controlling hard roofs, has become an effective means of controlling hard, difficult-to-cross roofs in my country's coal mines. Pre-fractured roofs by injecting high-pressure water can directionally fracture the roof strata, disrupting their integrity and thereby weakening their strength and integrity. This allows the roof to collapse on demand after mining, shortening the interval between initial and periodic pressure injections, thereby reducing or essentially eliminating the damage posed by hard roof strata to the mining face. Furthermore, compared to blasting, hydraulic fracturing offers advantages such as reduced engineering effort, increased safety, faster construction speed, better roof control, and greater adaptability.

[0003] After drilling is completed, the packer is pushed to the bottom of the borehole with a water injection drill pipe. Then, during the fracturing process, the packer is gradually withdrawn to the hole mouth, and the water injection rod needs to be frequently unscrewed. At present, the above work is all done manually with a low degree of mechanization, resulting in high labor intensity and low work efficiency for workers. Moreover, when the pressure is released after the fracturing is completed, the packer will rush out under the action of the pressure in the hole, and manual operation poses a great safety hazard. Summary of the Invention

[0004] In response to the above problems, the present invention provides a safe and efficient hydraulic fracturing operation robot with reasonable design and compact structure, which improves the safety and efficiency of hydraulic fracturing construction and reduces the labor intensity of workers.

[0005] In order to achieve the above object, the technical solution adopted by the present invention is:

[0006] A hydraulic fracturing safe and efficient operation robot comprises a camera, a front clamp, a rear clamp and a motor, a column, a rotating platform, a lifting cylinder, a hydraulic system, a control panel, a rod storage vehicle, a traveling mechanism, a mobile platform, a supporting cylinder and a rotating motor.

[0007] The camera, front clamp, rear clamp and motor are installed on a rotating platform.

[0008] The upright column, rotating platform and lifting oil cylinder are installed on the mobile platform.

[0009] The front clamp adopts a normally open mechanism in which a spring releases the water injection rod and a hydraulic cylinder clamps the water injection rod to provide reliable clamping force.

[0010] Compared with the prior art, the present invention has the following beneficial effects:

[0011] The present invention has reasonable design and compact structure, improves the safety and efficiency of hydraulic fracturing construction, and reduces the labor intensity of workers. BRIEF DESCRIPTION OF THE DRAWINGS

[0013] Figure 2 It is a structural schematic diagram of the present invention. DETAILED DESCRIPTION

[0014] See attached Figure 1 、 2 A safe and efficient hydraulic fracturing robot includes a camera 1, a front gripper 2, a rear gripper and motor 3, a column 4, a rotating platform 5, a lifting cylinder 6, a hydraulic system 7, an operating console 8, a rod storage vehicle 9, a traveling mechanism 10, a mobile platform 11, a supporting cylinder 12, and a rotating motor 13. The camera, front gripper, rear gripper, and motor are mounted on the rotating platform. The column, rotating platform, and lifting cylinder are mounted on the mobile platform.

[0015] At the site of installing the water injection rod, the supporting cylinder 12 lifts the hydraulic fracturing safe and efficient operation robot as a whole and off the ground, raising the column 4 to the top plate. The camera 1, rotating motor 13, lifting cylinder 6, and moving platform 11 align the water injection rod mounting hole of the front clamp 2 with the drill hole. The water injection rod is installed on the rear clamp and motor 3, which tightens the water injection rod. The cylinder installed on the rotating platform 5 moves the rear clamp and motor 3 along the guide rail on the rotating platform 5, passing through the front clamp 2 and entering the drill hole. The front clamp 2 then clamps the water injection rod, while the rear clamp and motor 3 release the water injection rod and retreat. Another water injection rod is installed into the previous water injection rod connector, the rear clamp 3 is released, and the (rear clamp and) motor 3 are rotated to tightly connect the two water injection rods through the threads. The above process is repeated until the water injection rod meets the drilling depth requirements. The front clamp adopts a normally open mechanism in which a spring releases the water injection rod and a hydraulic cylinder clamps the water injection rod to provide reliable clamping force.

[0016] The water injection rod is placed in the rod storage vehicle 9, and the traveling mechanism 10 enables the hydraulic fracturing safe and efficient operation robot to travel to the water injection pre-cracking roof site.

Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein.
