Abstract
The utility model relates to a hydraulic rock cracking apparatus, comprising a hydraulic source and a rock bulger; wherein the rock bulger has a rubber hydraulic chamber which can flex and bulgy; the two ends of the rubber hydraulic chamber has an upper taper bulging block and a lower taper bulging block; and a swelling housing is arranged at the outer of the rubber hydraulic chamber and the taper bulging blocks, which consists of three petals or more. One end of the rubber hydraulic chamber is provided with a tube joint and a steel bar and is connected to a high pressure oil pump through a rapid joint. The outer of the swelling housing has a snap ring which assembles the swelling housing. The utility model adopts hydraulic pressure as drive, is simple in structure, convenient to be operated, economic and practice; moreover, the stock bulger can be reused.
Description
Technical field
The utility model relates to a kind of rock mining device, particularly a kind of split device of rock of hydraulic coupling that utilizes.
Technical background
In mining industry and builing industry, need from the Nature, exploit rock, the rock work of splitting that large rock mass is become the fritter rock is the work that at first will carry out.
Common way is to bore plurality of holes on large rock mass, then explosive is loaded into, and implements explosion, and rock is split; Or in hole, add the chemicals that can carry out the expansion of chemical reaction volume, because of its volume expansion, rock is split.
Explosion method is wayward, and the chemically expansible method is uneconomical, and effect is not very good yet.
Summary of the invention
The purpose of this utility model provides a kind of simple in structure, and is economical and practical, and that can use repeatedly utilizes the split device of rock of hydraulic coupling.
The utility model is to realize like this.It comprises hydraulic power source and rock-swelling device two parts.In rock-swelling device, be provided with a rubber hydraulic pressure chamber that can stretch and expand, be provided with the bloated piece of upper and lower taper at the two ends of rubber hydraulic pressure chamber, be provided with an expansion shell of forming by three lobes or many lobes in the outside of rubber hydraulic pressure chamber and the bloated piece of taper.End at the rubber hydraulic pressure chamber is provided with union and steel pipe, and is connected with high-pressure oil pump by snap joint.Be provided with three or more in the outside of expansion shell with its snap ring that assembles up.
The course of work is such.On rock, bore plurality of holes, rock-swelling device is placed in the hole of rock, again high-pressure oil pipe and high-pressure oil pump are coupled together, after starting high-pressure oil pump, hydraulic oil feeds in the rubber hydraulic pressure chamber, owing to itself having elasticity, the rubber hydraulic pressure chamber expands change greatly, promoting the bloated piece of its upper and lower taper outwards moves along axis, promoting many lobes expansion shell radially increases, behind the bore hole size of size greater than rock, many lobes expansion shell will push rock, when extruding force during greater than the maximum stress of rock, rock will be opened by squeeze crack, reach the purpose of splitting rock.Reclaim rock-swelling device after splitting rock, can reuse through the cleaning maintenance.
The utlity model has tangible advantage.It with the hydraulic coupling is power, and is simple in structure, easy to operate, economical and practical, and rock-swelling device can reclaim use repeatedly.
