Embodiment 1

[0034] Such as figure 1 As shown, the embodiment discloses a vehicle-mounted drilling rig powered by dual diesel engines, comprising an automobile chassis 1, a chassis diesel engine 2, a gearbox 3, a fuel tank 4, a pump unit, an upper diesel engine 7, a transfer case 8, a mast 9, 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 output port is connected to the f...

Embodiment 2

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

[0044] When the vehicle-mounted drilling rig is working normally, use the bodywork diesel engine 7 and the chassis diesel engine 2 simultaneously or either as the power source of the vehicle-mounted drilling rig, wherein, when using the bodywork diesel engine 7 as the power source of the drilling rig, the sandwich power take-off clutch is opened, and the sandwich power take-off 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 clutch is combined to drive the first pump group 5; the power of the top-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 bodywork diesel engine 7 work simultaneously, they can meet the maximum flow demand of the hy...

Abstract

The invention discloses a vehicle-mounted drilling rig powered by dual diesel engines and a control method thereof. , hydraulic valve group and power control system; through the optimally designed drilling rig hydraulic system, both the top-mounted diesel engine and the chassis diesel engine can be independently used as the power source of the hydraulic system of the vehicle-mounted drilling rig, and the power switching of the drilling rig is convenient and flexible. While meeting the power requirements of the drilling rig, the power source can be switched according to the needs to realize non-stop drilling maintenance and maintenance of the power system of the drilling rig. Since the chassis diesel engine of the drilling rig is also the power source of the hydraulic system of the vehicle-mounted drilling rig, the frequency of use of the chassis diesel engine can be increased, and the power configuration of the diesel engine on the body can be greatly reduced.

Description

technical field [0001] The invention relates to the field of drilling equipment, in particular to a vehicle-mounted drilling rig powered by dual diesel engines and a control method thereof. Background technique [0002] The main power system, control system, and actuators of the vehicle-mounted drilling rig are all integrated on the chassis of the vehicle. After the drilling rig enters the site, it only needs relatively simple preparations to start drilling operations. Vehicle-mounted drilling rigs have the advantages of convenient transportation and short drilling time, and are widely used in the construction of ground coalbed methane drainage holes, cable holes, shallow oil drilling holes and mine ground rescue holes. The chassis and the upper part of the existing vehicle-mounted drilling rig are two relatively independent units. Since the power of the diesel engine of the chassis cannot meet the power requirements of the drilling rig, the chassis only undertakes the trans...
