[0002] At present, while coal mine operators focus on reducing manpower and increasing efficiency, the requirements for safe production have been greatly improved, and coal mine safety is the top priority. Among them, many sudden coal mine disasters are caused by rock burst, and the hazards of rock burst are sudden and sudden. With the requirements of anti-bumping and pressure relief, most of the special pressure relief tools on the domestic market are column-type hydraulic rotary drilling rigs modified from other construction equipment. This type of drilling rig has a simple structure and uses hydraulics as a power source for propulsion and rotation, which basically meets the construction requirements.

[0003] However, this drilling rig is not a special drilling rig for working face blasting construction. Its large size makes it difficult to move the drilling rig and it cannot adapt to the narrow construction conditions of the coal mining face. At the same time, the heat dissipation efficiency is low, resulting in excessively high oil temperature during operation. The drilling rig can only be shut down for cooling frequently, resulting in a high failure rate of the hydraulic system and affecting the service life of the hydraulic motor.

[0004] Therefore, the prior art needs to be further developed. Utility Model Content

[0029] By setting the first bottom plate 1, the entire oil tank is divided into small chambers in series. The high-temperature hydraulic oil input into the oil return chamber 311 by the drilling execution unit is gradually cooled down through the oil drain chamber 2 and then enters the oil suction chamber 312. It then re-enters the drilling execution unit through the oil suction chamber 312 to produce the effect of separating hot and cold oil, making the hydraulic oil flow through a longer path, so that the hydraulic oil obtains more sufficient heat dissipation space and has a better heat dissipation effect, thereby solving the technical problem of low heat dissipation efficiency of drilling rigs in related technologies.

[0030] Specifically, the first base plate 1 is connected to the track frame 101, and the first base plate 1 is located above the track frame 101. The motor pump unit and heat dissipation device of the drilling rig are installed above the oil tank 20. The oil tank has the same width as the drilling rig frame.

The volume of the entire track frame can be used as the volume of the oil tank, thereby increasing the capacity of the oil tank 20 and being able to accommodate more hydraulic oil in a limited space. At the same time, the overall width of the drilling rig is reduced, and the overall volume of the drilling rig equipment is reduced, making it easier to move the drilling rig underground, improving the heat dissipation efficiency of the oil tank, reducing the failure rate of the drilling rig, and increasing the service life of the drilling rig and the hydraulic system.
