Embodiment 1

[0038] Such as Figure 1 to Figure 4 As shown, the present embodiment provides a vehicle-mounted drilling rig power head and a test bench centering device, including a translation system 1, a drilling rig vehicle 2 arranged on the translation system 1, a vertical rear support 3 arranged at the rear end of the drilling rig vehicle 2, The feeding frame 5 that is positioned above the drilling machine 2 and the rear frame 3 and is hinged to the upper end of the rear frame 3 through the hinge shaft 4, the power head 6 that is arranged on the feed frame 5 and is parallel to the feed frame 5, is located on the The laser signal emitter 7 at the lower end of the rear part of the feed fuselage 5 and the laser emission direction is perpendicular to the feed fuselage 5, the drilling rig performance test bench 8 located below the laser signal emitter 7, and the horizontal level on the drill rig performance test bench 8. The laser signal receiving dish 9 of layout; The central axis of power...

Embodiment 2

[0045] This embodiment also provides a method for centering the power head of the vehicle-mounted drilling rig and the test bench, which is realized by using the centering device for the power head of the vehicle-mounted drilling rig and the test bench in Embodiment 1;

[0046] Specifically include the following steps:

[0047] In the first step, the driver drives the drilling rig to the designated position, so that the outriggers of the drilling rig are within the range of the left mobile platform and the right mobile platform, and the laser signal transmitter can be projected onto the laser signal receiving plate to complete the performance test of the power head and the drilling rig rough centering;

[0048] In the second step, according to the projection position of the laser signal transmitter received by the laser signal receiving disc, the left mobile platform and the right mobile platform move synchronously, and the right X-direction worktable and the right Y-direction...

Abstract

The invention discloses a centering device and method for a power head of a vehicle-mounted drilling rig and a test bench. The device includes a translation system, a drilling rig car, a feeding body, a power head, a laser signal transmitter, a performance test bench of a drilling rig, and a laser signal receiving plate The translation system includes hydraulic system, flow distribution valve group, X right translation cylinder and Y right translation cylinder, right moving platform, X left translation cylinder and Y left translation cylinder, left moving platform. The invention determines the moving direction and distance of the translation system through the laser signal transmitter and the laser signal receiving plate, and uses electro-hydraulic control to control the movement of the left and right mobile platforms, so as to realize the vehicle-mounted drilling rig as a whole in the coordinate system with the center of the drilling rig performance test bench as the coordinate origin. Translate in the Y direction, cooperate with the movement of the feeder body, power head, and drilling rig to complete the precise alignment between the center of the power head and the center of the test bench, avoiding the failure of the test bench caused by the additional lateral force caused by insufficient alignment accuracy, and ensuring that the on-board Drilling rig performance testing went smoothly.

Description

technical field [0001] The invention belongs to the technical field of drilling equipment testing, and in particular relates to a centering device and method for a power head of a vehicle-mounted drilling rig and a test bench. Background technique [0002] Most domestic vehicle-mounted drilling rig manufacturers do not have drilling rig performance test benches, and can only calculate the performance parameters of the drilling rig theoretically, and test the performance of the equipment during engineering construction. When problems arise, it is difficult to solve, time-consuming, laborious, and costly. . The more advanced test bench has a performance test platform with load spectrum dynamic loading, which can dynamically detect the torque and pull-out force at the same time, and restore the actual working conditions of the drilling rig to the greatest extent, which is helpful for researchers to find out the performance of the vehicle-mounted drilling rig and ensure that the...
