Description
Technical Field
The invention belongs to the technical field of coal mine industry, and relates to an improvement method of a full-hydraulic crawler-type gallery drilling machine push-pull cylinder for ZDY3200L coal mines.
Background
The crawler-type full-hydraulic tunnel drilling machine for the conventional ZDY3200L coal mine in the mine is easy to damage, has more maintenance times and large maintenance time ratio, and influences the drilling construction footage. The main reasons for the analysis are: (1) the hydraulic drilling machine has a plurality of vulnerable parts, such as hydraulic push-pull cylinders, slips, pump stations and the like (2), the performance of the drilling machine is not clear (3), the underground environment corrodes equipment, and impurities block a hydraulic system.
Disclosure of Invention
The ZDY3200L coal mining full-hydraulic tunnel drilling machine push-pull cylinder improvement technology is characterized in that on the premise of existing mine equipment, a damaged push-pull cylinder on a ZDY3200L drilling machine is replaced by a push-pull cylinder eliminated by a hydraulic support, so that the damage resistance and resistance of the drilling machine are improved, the maintenance cost is reduced, and the maintenance frequency is reduced, thereby accelerating the drilling construction progress, improving the single advance of the drilling machine, shortening the outburst elimination engineering construction time and reducing the investment.
The invention aims to solve the problems and provides an improved method for a push-pull cylinder of a ZDY3200L coal mining full-hydraulic crawler-type gallery drilling machine, 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 improvement method of a full-hydraulic crawler-type gallery drilling machine push-pull cylinder for ZDY3200L coal mines comprises the following steps:

2) disassembling the hydraulic propulsion system;
B. machining an oil cylinder and modifying a propulsion system;
1) the hydraulic support push-pull cylinder is short, and a connecting sleeve which is extended by 15 cm needs to be welded at the rear part of the cylinder body so as to meet the requirements of 3200L of drill carriage and body length;
2) disassembling the hydraulic support cylinder barrel, welding and blocking redundant oil inlets and oil outlets at the upper part and the lower part, reducing the diameter of the reserved inlet and outlet, and polishing the flatness of each inlet and outlet to prevent liquid leakage;
3) processing a variable joint, drilling a hole for fixing an oil cylinder on a drilling machine body and aligning a long screw;
4) installing a push-pull cylinder, and connecting the high-pressure rubber pipe with a pump station and an operation platform respectively in sequence;
5) and (5) commissioning and further debugging.
