Coal mine gas control bottom pumping roadway 90-degree all-round hydraulic drilling rig working mechanism

Abstract

The invention relates to an operation mechanism for a ninety-degree full-directional hydraulic drill carriage for a coal-mine gas control end-located drainage roadway. The operation mechanism comprises a lifting mechanism (2.1), a horizontally-moving compensation mechanism (2.2) and a rotary mechanism (2.3), the lifting mechanism (2.1) is installed on a main engine body (1), the rotary mechanism (2.3) is connected to the lifting mechanism (2.1), and the rotary mechanism (2.3) is connected to the rotary mechanism (2.3). The operation mechanism for the ninety-degree full-directional hydraulic drill carriage for the coal-mine gas control end-located drainage roadway has the advantages of being convenient to construct and high in stability.

Description

technical field [0001] The invention relates to a working mechanism for a 90-degree omni-directional hydraulic drilling vehicle in a coal mine gas control bottom pumping roadway, belonging to the technical field of mining equipment. Background technique [0002] At present, in order to solve the shortage of drilling rigs in coal mine roadways, the company applied for the Chinese patent ZL201220128380.3 "90°rotating coal mine deep hole drilling rig" on March 20, 2012. the following questions; [0003] In the coal mining industry, when coal mining operations are carried out underground, it is necessary to conduct drilling work such as water exploration, gas exploration, fault detection, water injection, etc. on the coal seam, so the operating location will continue to change, so a self-moving crawler deep hole drilling rig is required Come to work in order to punch holes in different places. However, even at the same place underground, the angle and height of the hole to be ...

AI Technical Summary

Problems solved by technology

However, the rotation angle between the piston rod of the oil cylinder and the carriage assembly is limited. Once the rotation is too large, the oil cylinder will not be able to support the carriage assembly. Therefore, the working mechanism of the deep hole drilling rig in the past can only rotate at an angle of 0~45°. As a result, the drilling angle range of the deep hole drilling rig is limited, making it less applicable

[0006] 2. In the past, the chuck and the power head of the deep hole drilling rig are respectively arranged on the front and rear sides of the slide seat. However, when the rotary support assembly rotates, the chuck is easy to touch the support column at its front end, thus damaging the chuck

[0007] 3. In the past, the deep hole drilling rig was only equipped with a support column in the middle of the drilling rig to fix the deep hole drilling rig. However, since the working mechanism of the deep hole drilling rig is set at the rear end of the drilling rig, the working mechanism holds the When the drill pipe rotates at high speed, the working mechanism will also vibrate, which will damage the mechanical components of the working mechanism in the long run, thus affecting its service life

[0008] 4. In the past, the hydraulic valve of the deep hole drilling rig was set on the hydraulic station which was set separately from the deep hole drilling rig, and the hydraulic station was connected to the deep hole drilling rig through the oil pipe. However, the hydraulic station and the deep hole drilling rig occupied a large amount of space. space, it is extremely unsuitable in mines with small lanes

[0009] 5. In the past, there were two support columns in the middle of the deep hole drilling rig, resulting in a large width of the deep hole drilling rig, which was not suitable for some narrow coal mine roadways;

[0010] Although the drilling rig developed and applied by our company solves the above-mentioned major problems, it is also slightly insufficient for some special sites; for example, for some narrow coal mine roadways for construction operations, the rotation angle of the working mechanism of the above-mentioned drilling rig is often unable to display; at the same time , due to the lack of corresponding support mechanism, the above-mentioned drilling rig is not stable enough when working, which affects the construction effect
