Double-cylinder force-increased splitter

Abstract

The invention discloses a double-cylinder force-increased splitter. The splitter comprises a base, a splitting block, a wedge block, a piston rod, a pair of pistons and a pair of cylinder bodies, wherein the pair of cylinder bodies are connected in series, one of the cylinder bodies is connected with one end of the base, and the other end of the base is connected with the splitting block; the pairof pistons are arranged in inner cavities of the corresponding cylinder bodies in a sleeved mode, and the two ends of the piston rods are connected with the corresponding pistons; and the wedge blockis arranged in the splitting block in a penetrating mode and connected with the piston rod, force application oil inlets are formed in the ends, far away from the base, of the pair of cylinder bodies, and a reset oil inlet is formed in the end, close to the base, of one cylinder body far away from the base. The double-cylinder force-increased splitter has the advantages of being simple in structure, flexible to use, capable of improving splitting accuracy, beneficial to weight reduction and capable of avoiding hydraulic oil leakage.

Description

Technical field [0001] The invention mainly relates to stone mining technology, in particular to a double-cylinder force booster splitter. Background technique [0002] At present, explosive blasting and splitting methods are generally used in stone mining. Due to the high risk of explosive blasting, high safety and stability, environmental pollution, waste of resources and other problems, explosive blasting is not allowed on many occasions. The splitting machine splitting method has low cost, simple operation, safety and reliability. [0003] In the prior art, the splitter is driven by a single oil cylinder. When facing the hard stone, it is necessary to increase the driving force to realize the mining. This single-cylinder splitter is obviously not applicable. The current solution is to increase Boosting valve or increasing the piston diameter to achieve boosting, both of these methods greatly increase the radial size of the splitter. On the one hand, the splitter is bulky when...

AI Technical Summary

Problems solved by technology

[0003] In the prior art, the splitters are all driven by a single oil cylinder. When faced with stones with high hardness, it is necessary to increase the driving force to realize mining. This kind of single-cylinder splitter is obviously not suitable. The current solution is to increase Boost valve or increase the diameter of the piston to achieve boost, these two methods greatly increase the radial size of the splitter, on the one hand, the splitter is very bulky when used, which affects the flexibility of use; on the other hand , when the splitter is used, the force is applied axially. The increase in the radial dimension will easily cause deflection when the force is applied axially, which affects the accuracy of splitting.
