Abstract

The invention belongs to the technical field of rock splitting, and particularly relates to a splitting rod with a series connection structure. Splitting rod bodies are provided with a plurality of cavities used for installing pistons, and the cavities are divided into first cavities and second cavities by the pistons; and the two ends of each splitting rod body are further provided with first oilinlets communicating with the first cavities, and second oil inlets communicating with the second cavities. According to the splitting rod, quick couplings and connecting pipelines are added, so thatthe multiple splitting rod bodies are connected in series through the quick couplings; the first oil inlets of the multiple splitting rod bodies communicate with each other through the connecting pipelines, and the second oil inlets communicate with each other; oil lines communicate with each other after series connection is achieved; hydraulic oil is fed through the first oil inlets or the second oil inlets on one side so that synchronous control over the pistons on the splitting rod bodies connected in series is achieved. By using the simple structure, series connection of the multiple splitting rod bodies is achieved.

Description

【Technical field】 [0001] The invention belongs to the technical field of rock splitting, in particular to a splitting rod with a series connection structure. 【Background technique】 [0002] In traditional rock and mine mining, most of the rock is broken by blasting. However, with the development of my country's economy, environmental protection and construction personnel's safety considerations, the control of blasting is very strict. Only qualified companies with professional blasting qualifications can carry out blasting operations, resulting in an increasing cost of blasting. [0003] Now there are non-explosive rock breaking methods, such as the use of splitting rods, which use the hydraulic system as power, put the splitting rod into the pre-blind hole in the rock, and push the piston on the splitting rod out through hydraulic power. On the inner wall of the rock, the rock is broken from the inside, so as to achieve the rock cracking effect. [0004] However, due to t...
