[0030] Example 1

[0031] like Figure 1 As shown, the utility model provides a light and high-efficiency crawler drilling rig, including a drilling rig platform 1, which is installed on a crawler chassis 2. In this embodiment, a light and wide rubber crawler geophysical drilling rig crawler chassis is used as the carrying chassis of the drilling rig, which can increase the ground contact area, reduce the ground contact pressure ratio, and ensure the drilling rig's passability.

[0032] The drilling rig platform 1 is equipped with a cab 3, a fuel tank assembly 4, a mud circulation assembly 10, a water tank 11, an engine assembly 13, and a transmission assembly 14. A derrick assembly 7 is mounted on one side of the drilling rig platform 1 via a bracket 5. The power head assembly is mounted on the derrick assembly 7. The engine assembly 13 is connected to the mud circulation assembly 10, transmission assembly 14, derrick assembly 7, and power head assembly via a hydraulic system. A radiator 17 is mounted on the drilling rig platform 1 below the fuel tank assembly 4 to maintain a stable temperature and prevent overheating.

[0033] The engine assembly 13 uses a diesel engine to provide power output, providing strong power to the various working assemblies of the drilling rig. The hydraulic system includes a variable displacement pump 15 and a gear pump 16 installed at the output end of the engine assembly 13. The engine assembly 13 drives the variable displacement pump 15 and the gear pump 16 through a coupling. Both the variable displacement pump 15 and the gear pump 16 are connected to the transmission assembly 14, the mud circulation assembly 10, the derrick assembly 7, and the power head assembly via a hydraulic valve assembly 12, thereby outputting power from the engine assembly 13 to the various working assemblies.

[0034] Hydraulic valve assembly 12 includes a gear pump multi-way valve 121 and a variable pump multi-way valve 122. Variable pump 15 is connected to variable pump multi-way valve 122 via a pipeline, while gear pump 16 is connected to gear pump multi-way valve 121 via a pipeline. Gear pump multi-way valve 121 is also connected to the derrick oil cylinder 6 via a pipeline to provide power output for retracting and extending the derrick assembly 7.

[0035] The transmission assembly 14 includes a transmission body 141, a pilot valve 143, and a steering valve 145. A transmission control assembly 142, a steering cylinder 144, and a bent-axis motor 146 are mounted on the transmission body 141. The pilot valve 143, steering valve 145, and transmission control assembly 142 are all located within the cab 3, facilitating operator control of the drilling rig.

[0036] The variable pump multi-way valve 122 is connected to the pilot valve 143 and the bevel-axis motor 146 via pipelines. Feedback control of the variable pump multi-way valve 122 is provided by the pilot valve 143, thereby adjusting the hydraulic fluid supply from the variable pump multi-way valve 122 to the bevel-axis motor 146, thereby controlling the operation of the bevel-axis motor 146 and driving the transmission body 141 and the tracked chassis 2. The gear pump multi-way valve 121 is connected to the steering valve 145 via pipelines, which in turn is connected to the steering cylinder 144 via pipelines. Control of the steering valve 145 regulates the operating state of the steering cylinder 144. The steering cylinder 144 can be understood as two hydraulic cylinders in a row, each end of which bears against the transmission's steering arm. When the handle of the steering valve 145 is turned to the right, the right hydraulic cylinder extends and rotates the steering arm a certain angle, thereby achieving steering.

[0037] The top of the water tank 11 is equipped with a top cover 111, which facilitates adding water to the water tank 11. A drain pipe 112 is connected to the bottom of the water tank 11. The outlet end of the drain pipe 112 is movably fixed to the side of the water tank 11. When draining water, the drain pipe 112 is removed, and gravity allows all the water in the water tank 11 to flow out. The operator can control the amount of water released according to actual water demand to avoid waste.

[0038] The mud circulation assembly 10 includes a mud pump 101 mounted on the drilling rig platform 1. A mud pump motor 102 is connected to one side of the mud pump 101. A gear pump multi-way valve 121 is connected to the mud pump motor 102 via a pipeline, providing power to the mud pump motor 102. The inlet of the mud pump 101 is connected to a suction showerhead 104 via a mud pump suction pipe 103. The outlet of the mud pump 101 is connected to the power head assembly via a mud pump outlet pipe 105.

[0039] The powerhead assembly includes a powerhead 8 mounted on the derrick assembly 7. A rotary motor 18 is connected to the powerhead 8, which is connected to a variable pump multi-way valve 122 via a pipeline to obtain power output from the engine assembly 13. A drilling tool 9 is mounted on the powerhead 8. The drilling tool 9 is movably mounted on the powerhead 8, allowing the appropriate drilling tool to be selected based on different usage requirements. The lower portion of the drilling tool 9 is movably fixed to the bottom of the derrick assembly 7, providing horizontal support for the drilling tool 9 and ensuring more stable operation.

[0040] The derrick assembly 7 is provided with a pressurized lifting motor 19, which is connected to a variable pump multi-way valve 122 via a pipeline to control the raising and lowering of the derrick assembly 7, thereby driving the drilling tool 9 up and down. Since the derrick assembly 7 is conventional, it will not be described in detail here.

[0041] During drilling, water from the water tank 11 is discharged into the excavated mud pit, forming a flushing medium for mud drilling. Next, the suction showerhead 104 of the mud pump suction pipe 103 is placed in the mud pit. The mud pump motor 102 drives the mud pump 101, directing the flushing medium through the mud pump outlet pipe 105 to the power head 8 mounted on the derrick assembly 7. Finally, the flushing medium is introduced into the wellbore through the drilling tool 9, flushing out rock cuttings and completing the well-flushing process for mud drilling.

[0042] Therefore, the utility model adopts the above-mentioned light and high-efficiency crawler drilling rig, which can increase the contact area with the ground, improve the drilling rig's passing ability, can be applied to more complex terrains, and also has the ability to carry well washing media, which is conducive to improving work efficiency.

[0043] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the present invention rather than to limit it. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that they can still modify or replace the technical solution of the present invention with equivalents, and these modifications or equivalent replacements cannot cause the modified technical solution to deviate from the spirit and scope of the technical solution of the present invention.
