Problems solved by technology

[0003] Existing coring drilling rigs are usually installed on a trolley. When the position of the drilling rig needs to be adjusted, the trolley can only be moved manually, and the drilling rig needs to be moved as a whole for adjustment. This adjustment method has low adjustment accuracy and cannot accurately locate the working position. For example: When the drilling rig is working on the ground with a certain slope, it is difficult for the drilling rig to adjust the angle to keep the working rod level with the ground, thus affecting the quality of the work, and the adjustment efficiency of the overall movement of the trolley is low

Embodiment Construction

[0013] The present invention will be further described below in conjunction with accompanying drawing.

[0014] Such as figure 1 with figure 2 As shown, a mast adjustment mechanism of a coring drilling rig of the present invention includes a lifting cylinder 4, a connecting rod 6, a front and rear angle adjustment cylinder 15, and a mast 17; The mast 17 is provided with a guide rail 13, and the lower part of the cylinder body of the lifting cylinder 4 is connected with the connecting rod 6 through the pin shaft 5, and the connecting rod 6 is installed on the vehicle frame; 14, the other end is hinged on the ear seat six 16 on one side of the lift cylinder 4, and the front and rear angle adjustment oil cylinder 15 is telescopic, so that the mast 17 is rotated forward and backward with the bearing pin 5 as the center to adjust the angle. Here, the front and rear directions are figure 1 in the front-back direction (i.e. figure 2 in the left-right direction). When working, w...

Abstract

The invention discloses a coring drilling machine mast adjusting mechanism which comprises a lifting oil cylinder, a connecting rod, a front-back angle adjusting oil cylinder and a mast. The upper portion of the lifting oil cylinder is hinged to the mast through a piston rod. The mast is provided with a first guide rail. The lower portion of a cylinder body of the lifting oil cylinder is connected with the connecting rod through a pin shaft. The connecting rod is installed on a vehicle frame. One end of the front-back angle adjusting oil cylinder is hinged to the connecting rod, and the other end of the front-back angle adjusting oil cylinder is hinged to one side of the lifting oil cylinder. The front-back angle adjusting oil cylinder stretches and retracts, so that the mast rotates around the pin shaft to adjust the angle. A left-right sliding oil cylinder can adjust the mast to move in the left-right direction, and therefore an operation positioning point can be conveniently found. A left-right angle adjusting oil cylinder and the front-back angle adjusting oil cylinder can adjust the mast to achieve angle adjustment in the left-right and front-back directions, so that no matter in which direction the operation place has the gradient, the perpendicularity of the mast and the operation point can be always ensured, the operation position is accurately positioned, and operation quality and efficiency are improved.

Description

technical field [0001] The invention relates to a core drilling machine, in particular to a core drilling machine mast adjustment mechanism. Background technique [0002] Concrete drilling and coring machine (also known as water drill) mainly has two purposes, one is for horizontal drilling, it is suitable for road stud installation, road pile installation, bridge drilling operation rules, integrated house pile foundation drilling, etc., has been widely used It is used in transportation engineering companies, China Railway Group, integrated housing companies and other units; the second is for coring, which is suitable for road surface coring for testing, and has been widely used in testing centers around the world. [0003] Existing coring drilling rigs are usually installed on a trolley. When the position of the drilling rig needs to be adjusted, the trolley can only be moved manually, and the drilling rig needs to be moved as a whole for adjustment. This adjustment method ...
