Problems solved by technology

This phenomenon is particularly prominent in the initial stage of pressure relief, and it is a very troublesome problem in the field of hydraulic ultra-high pressure applications. The oil time is extended. In the field of hydraulic ultra-high pressure, the maximum rated working pressure of the ultra-high pressure electromagnetic directional valve currently available on the market can only reach 70MPa. When the pressure is higher, there is no corresponding electromagnetic directional valve product. 70MPa hydraulic pressure It is very difficult to automate the ultra-high pressure system, especially the hydraulic ultra-high pressure system above 100MPa, which cannot be automatically controlled by conventional hydraulic circuit means at present

Embodiment Construction

[0027] The present invention will be further elaborated below in conjunction with accompanying drawing, wherein, the direction of the present invention is with figure 1 as standard.

[0028] Such as figure 1 with 2 As shown, the fully automatic rock splitter of the present invention includes a hydraulic station 1, a distributor 2, four rock splitter rods 3, a hydraulic pipe 4, a one-way valve 5 and a pressure relief valve 6, and one of the branches of the hydraulic station 1 outputs high-pressure oil , the high-pressure oil flows into the distributor 2 in one direction through the one-way valve 5, and the distributor 2 injects the oil into the four cracking rods 3 (rodless cavity) at equal pressure, so as to realize the ejection of the four cracking rods 3 action to achieve the purpose of cracking rocks; another output branch of the hydraulic station 1 is high-pressure oil, and the high-pressure oil is injected into the pressure relief valve 6, so as to realize the opening o...

Abstract

The invention discloses a full-automatic stone cracking machine which is simple in structure, convenient to control, higher in work efficiency, better in stone cracking effect, higher in continuity and free of pollution and noise, and a pressure relief valve is controlled more conveniently and rapidly. The full-automatic stone cracking machine comprises a hydraulic station, multiple stone cracking bars, hydraulic pipes, a one-way valve and the pressure relief valve. The hydraulic station communicates with the one-way valve through the corresponding hydraulic pipe. The one-way valve communicates with the stone cracking bars through the corresponding hydraulic pipes so that oil liquid in the hydraulic station can be conveyed out to each stone cracking bar in the single direction. The stone cracking bars communicate with the pressure relief valve through the corresponding hydraulic pipes. The pressure relief valve communicates with the hydraulic station through the corresponding two hydraulic pipes; when each stone cracking bar is ejected out, the pressure relief valve is in a closed state; and when each stone cracking bar contracts, the oil liquid in the hydraulic station can control opening and closing of the pressure relief valve through one hydraulic pipe, and the oil liquid in each rock cracking bar flows back to the hydraulic station through the other hydraulic pipe.

Description

technical field [0001] The present invention relates to a valve, in particular, to a valve with simple structure, convenient control, higher work efficiency, better effect of rock cracking, stronger continuity, no pollution, no noise, and more convenient and quick control of the pressure relief valve. fully automatic rock cracker. Background technique [0002] Rock cracking equipment is a new type of construction equipment that splits rocks from the ground. At present, most construction methods use non-blasting construction methods, that is, using stone breakers, expansion agents, crushing equipment (such as breaking hammers, etc.), hook machines, and wire saws. , disc saw, flame cutting and water cutting equipment operation. [0003] Wire sawing, disc sawing, flame cutting, and water cutting belong to surface processing construction methods, which need to cut the entire section on the rock, which has low efficiency, high energy consumption, and less one-time investment in ...
