Embodiment 1

[0034] Such as figure 1 As shown, the embodiment discloses a dual diesel engine-powered vehicle-mounted drilling rig, including an automobile chassis 1, a chassis diesel engine 2, a gearbox 3, a fuel tank 4, a pump set, a bodywork diesel engine 7, a transfer case 8, a mast 9, and a power head 10. Outrigger 11, sandwich power take-off 12, hydraulic valve group 13, and power control system 14.

[0035] The pump set includes a first pump set 5 and a second pump set 6, and the first pump set 5 and the second pump set 6 suck oil from the same oil tank 4. The first pump group 5 includes a first main pump 5-1 and a first auxiliary pump 5-2, and the second pump group 6 includes a second main pump 6-1 and a second auxiliary pump 6-2. The input end of the sandwich power take-off 12 is connected to the chassis diesel engine 2, and the sandwich power take-off 12 is provided with two output ports, one of which is connected to the gearbox 3 and the other is connected to the first pump group 5....

Embodiment 2

[0043] This embodiment discloses a control method of a dual diesel engine-powered vehicle-mounted drilling rig, which includes:

[0044] When the vehicle-mounted rig is operating normally, use the top-mounted diesel engine 7 and the chassis diesel engine 2 as the power source of the vehicle-mounted rig at the same time or any one of them. When the top-mounted diesel engine 7 is used as the power source of the rig, the sandwich power take-off is opened and closed, 12 Does not work; when the chassis diesel engine 2 is used as the power source of the drilling rig, the sandwich power take-off is combined to drive the first pump set 5; the power of the mounted diesel engine 7 or the power of the chassis diesel engine 2 only needs to meet the normal drilling power requirements of the drilling rig; When the diesel engine 2 and the top-mounted diesel engine 7 work at the same time, they can meet the maximum flow demand of the hydraulic system;

[0045] When the upper diesel engine 7 needs ...

Abstract

The invention discloses a double-diesel-engine powered truck-mounted drilling rig and a control method thereof. The double-diesel-engine powered truck-mounted drilling rig comprises a truck chassis, achassis diesel engine, a gearbox, an oil tank, pump sets, a top-mounted diesel engine, a transfer case, a mast, a power head, an outrigger, a sandwich power take-off device, a hydraulic valve set anda power control system. According to the double-diesel-engine powered truck-mounted drilling rig, through an optimally designed drilling rig hydraulic system, the top-mounted diesel engine and the chassis diesel engine can independently serve as power sources of the truck-mounted drilling rig hydraulic system, and drilling rig power switching is convenient and flexible. On the premise of meetingthe drilling rig power requirement, the power sources can be switched as needed, and the drilling rig power system can be maintained without stopping drilling. As the chassis diesel engine of the drilling rig also serves as one power source of the truck-mounted drilling rig hydraulic system, the use frequency of the chassis diesel engine is improved, and the power configuration of the top-mounteddiesel engine can be greatly reduced. Thus, the production and use cost of the drilling rig can be reduced, and besides, a good energy conservation and emission reduction effect is achieved.

Description

Technical field [0001] The invention relates to the field of drilling equipment, in particular to a dual-diesel engine-powered vehicle-mounted drilling rig and a control method thereof. Background technique [0002] The main power system, control system, and actuator of the vehicle-mounted drilling rig are integrated on the chassis of the vehicle. After the drilling rig enters the site, the drilling operation can be started with relatively simple preparations. The truck-mounted drilling rig has the advantages of convenient transportation and short drilling time. It has been widely used in the construction of surface coalbed methane extraction holes, cable holes, shallow oil drilling and mine surface rescue holes. The chassis and the upper part of the existing truck-mounted drilling rig are two relatively independent units. Since the power of the chassis diesel engine cannot meet the power requirements of the drilling rig, the chassis only undertakes transportation work. When the ...
