Problems solved by technology
Long-term practical experience shows that this fixing method has the following three disadvantages: ①The fixing time is long
After the concrete foundation is poured, it takes a long time to fully solidify to meet the use requirements; ②The fixed strength is limited
The strength of concrete is limited, and the force of the drilling rig is often complicated when it is working. The use of concrete to fix the drilling rig lacks guarantee in terms of reliability.
③ Difficult to adjust
However, the support stability of the drilling rig support device in this patent is not high, and it is not adjustable, and the controllability is poor

The invention discloses an upper and lower four-top-support type fixing system of an underground drilling machine. The upper and lower four-top-support type fixing system comprises upper top support oil cylinders, lower top support oil cylinders, energy accumulators and hydraulic locks. The energy accumulators comprise the first energy accumulator and the second energy accumulator. The hydraulic locks comprise the first hydraulic lock and the second hydraulic lock. The upper top support oil cylinders are connected with the first energy accumulator through a first one-way valve. The lower top support oil cylinders are connected with the second energy accumulator through a second one-way valve. The upper top support oil cylinders are connected with the first hydraulic lock and a first reversing valve. The lower top support oil cylinders are connected with the second hydraulic lock and a second reversing valve. The upper and lower four-top-support type fixing system is simple in structure, convenient to use, high in controllability and good in stability.
Description
Technical field [0001] The invention belongs to the technical field of mining machinery, and in particular relates to an up-and-down four-top support type fixing system for an underground drilling rig. Background technique [0002] Underground drilling rigs are commonly used in underground mining. How to ensure that the drilling rigs accurately drill and the holes do not deviate has always been a major technical problem for underground drilling rigs. The fixing method of the main engine during the drilling process will greatly affect the drilling The accuracy of the direction. [0003] At present, the anchor bolts embedded in the concrete foundation are generally used to fix the main engine of underground drilling rigs, and a fixed shoe plate is designed on the main engine, and the drilling rig is fixed by bolting the shoe plate and the concrete. Long-term practical experience shows that this fixation method has the following three shortcomings: ①Long fixation time. After the con...
