Technical Field
The invention belongs to the technical field of coal mine industry, and relates to an improved method for a push-pull cylinder of a full-hydraulic crawler type tunnel drilling machine for a ZDY 3200L-shaped coal mine.
Background
The existing ZDY 3200L-type crawler-type full-hydraulic tunnel drilling machine for the coal mine is easy to damage, the maintenance times are high, the maintenance time is large, and the drilling construction footage is affected. The main reasons for its analysis are: the hydraulic drilling machine has more vulnerable parts, such as hydraulic push-pull cylinders, slips, pump stations and the like (2) operators have unclear drilling machine performance and (3) underground environment corrosion equipment and sundries block the hydraulic system.
Disclosure of Invention
The improved technology of the push-pull cylinder of the full-hydraulic tunnel drilling machine for the ZDY 3200L-shaped coal mine is that on the premise of existing equipment of a mine, the push-pull cylinder eliminated by a hydraulic support is used for replacing the damaged push-pull cylinder on the ZDY 3200L-shaped coal mine, so that the damage resistance and resistance of the drilling machine are improved, the maintenance cost is reduced, the maintenance times are reduced, the drilling construction progress is accelerated, the single advance of the drilling machine is improved, the outburst elimination engineering construction time is shortened, and the investment is reduced.
The invention aims to solve the problems and provide an improved method for the push-pull cylinder of the full-hydraulic crawler type tunnel drilling machine for the ZDY 3200L-shaped coal mine, which has the characteristics of prolonging the service life of equipment, improving the working efficiency, shortening the construction time, reducing the maintenance cost and the like.
The object of the invention is achieved in that: an improved method for a push-pull cylinder of a full-hydraulic crawler type tunnel drilling machine for a ZDY 3200L-shaped coal mine, which comprises the following steps:
A. removing a damaged push-pull cylinder of the ZDY3200L drilling machine;

2) Disassembling the hydraulic propulsion system;
B. processing a push-pull cylinder eliminated by a hydraulic support and reforming a propulsion system;
1) The push-pull cylinder eliminated by the hydraulic support is shorter, and a connecting sleeve which is 15 cm is welded and prolonged at the rear part of the cylinder body so as to meet the length of a carriage and a machine body of the 3200L drilling machine;
2) Disassembling cylinder barrels of push-pull cylinders eliminated by the hydraulic support, welding and plugging redundant oil inlet and outlet at the upper part and the lower part, reducing the diameters of the reserved oil inlet and outlet, polishing the flatness of each oil inlet and outlet, and preventing liquid leakage;
3) Machining a variable joint, punching holes for fixing a push-pull cylinder eliminated by a hydraulic support on a drill body, and preparing long screws;
4) The hydraulic support is arranged to eliminate the push-pull cylinder, and the high-pressure rubber tube is connected with the pump station and the operation table in sequence;
5) Run-in and further debug.
Detailed Description

The tables are connected; 5) Run-in and further debug.
The invention has the characteristics and effects that:
1) The diameter of the push-pull cylinder eliminated by the hydraulic support is large;
2) The drilling machine has high propelling strength, the construction progress is fast, and the cylinder body does not generate heat;
3) The anti-damage and resistant capabilities are strong, and the anti-damage and resistant effects are not easy to damage.
