Abstract
A shape memory alloy stone breaker is adaptable to cutting and breaking rocks, ores and concrete materials. The shape memory alloy stone breaker comprises a pressure transfer body consisting of two semi-cylinders, a plurality of shape memory alloy blocks are clamped inside the pressure transfer body, grooves for clamping the shape memory alloy blocks are symmetrically arranged inside the two semi-cylinders of the pressure transfer body, and spacer bodies clamped among the shape memory alloy blocks are arranged inside the grooves at intervals. The shape memory alloy stone breaker is placed into a rock drilling hole, heats the memory alloy blocks, leads shapes of the memory alloy blocks to be recovered so as to extend to directions of two sides of the pressure transfer body, transfers pressure to a rock through the pressure transfer body, and then presses to break the rock. The shape memory alloy stone breaker is safe without noise, shocking, flying stones, smokes, pollution or affecting surrounded environments and the like, is simple in structure, large in bursting force and fast in bursting speed and can be reused.
Description
Technical field
The utility model relates to the catalase technical field, especially relates to a kind of marmem and splits stone implement.
Background technology
Existing rock, concrete breaking method mainly contain: methods such as explosive blasting, static breaking agent and high-energy combustion agent.Though explosive blasting method efficiency of construction height is easy to generate environmental hazard effects such as air-shock wave, blasting flyrock, blasting vibration and Property of Blasting Noise, demolition accident such as also be easy to generate early quick-fried, hangfire, miss-fire.High-energy combustion agent utilizes the gas quasistatic to expand and the thermal stress fractured rock, but consumption also can produce slungshot when excessive, and higher to the filling quality requirement, and operation inconvenience often has unnecessary gas to spray along the crack and causes spray orifice after especially incendiary agent is lighted.The cost of high-energy combustion agent is also than 10～20 times of explosive costlinesses in addition.Though the static crushing agent method can be avoided explosion harm and accident, crushing efficiency is lower, and cost is higher, and breaking capacity is less simultaneously.So be badly in need of a kind of low cost, safe and reliable, speed of application is fast, the catalase device that environment and personnel's equipment is not constituted harm meets the demands.
Summary of the invention
The purpose of this utility model is the deficiency that overcomes in the prior art, provides a kind of environment harm simple in structure, easy to use, effective, no and reusable marmem to split stone implement.
For achieving the above object, marmem of the present utility model splits stone implement, comprise the pressure transmission body that two semicylinders constitute, be installed with polylith marmem piece in the pressure transmission body, symmetry has the groove that clamps polylith marmem piece in two semicylinders of pressure transmission body, is interval with the interval body that is installed between the polylith marmem piece in the groove.
Described marmem piece is Ti-Ni alloy, iron-based or the copper-based memory alloy with round trip memory function; Described pressure transmission body and function carbide alloy is made; Described interval body is metal derby, unit of plastic, wooden unit, block rubber or ceramic block.
Beneficial effect:
1, be cutting of a kind of physics and breaker, do not use any chemical material, have safety, noiselessness, shockproof, no slungshot, the no smoke of gunpowder, pollution-free, do not influence characteristics such as surrounding environment;
2, expansive force is big, can cut and broken Protodyakonov coefficient f=2～20 between each rocks and concrete;
3, cutting and crushing efficiency height, cracking time is short, just can make rock or concrete rupture in a few minutes;
4, make by memorial alloy, and have good wearability and corrosion resistance with round trip memory function, thereby rock expander repeat usage height;
5, stop heating after, the state when marmem splits stone implement and can automatically restore to normal temperature is convenient to take out.
6, labour intensity is low, and construction cost is low.
Description of drawings
Fig. 1 is the longitudinal sectional drawing that the utility model marmem splits stone implement.
Fig. 2 splits the A-A profile of stone implement for the utility model marmem.
Fig. 3 splits the B-B profile of stone implement for the utility model marmem.
The specific embodiment
Below in conjunction with accompanying drawing an embodiment of the present utility model is further described:
Marmem of the present utility model splits stone implement, is made up of pressure transmission body 1, polylith marmem piece 2 and interval body 3.Pressure transmission body 1 is made of two semicylinders, pressure transmission body 1 usefulness carbide alloy is made, the outer surface of semicylinder is smooth cambered surface, polylith marmem piece 2 is installed in the pressure transmission body 1, the front and back bilateral symmetry of marmem piece 2 has and makes the left and right sides form the groove of projection, and marmem piece 2 is memory Ti-Ni alloy, iron-based or the copper-based memory alloy with round trip memory function.Symmetry has the groove 4 that adapts with polylith marmem piece 2 boss in two semicylinders of pressure transmission body 1, be interval with the interval body 3 that is installed between the polylith marmem piece 2 in the groove 4, interval body 3 is metal derby, unit of plastic, wooden unit, block rubber or ceramic block.
Marmem is split stone implement put into the good rock-boring of brill, adopt in the hole, to be blown into hot blast or to adopt electric heater 2 heating of marmem piece.Under heat effect, marmem piece 2 produces recovery of shape at short notice and pushes the pressure transmission body 1 of both sides, thereby the bulbs of pressure of output and pass to rock make the rock effect of being stressed and broken.After splitting stone and finishing, stop heating, marmem piece 2 can be contracted to the state before the heating, and drives pressure transmission body 1 retraction of both sides, splits stone implement so that reclaim.After stone implement is split in taking-up, just can carry out next circulation construction.Can be during use according to broken requirement, a plurality of stone implements that split to be put into a plurality of borings that design respectively and heated simultaneously, a plurality of actings in conjunction of splitting stone implement can realize rock or concrete fragmentation.
