Abstract
A silent blast spalling device is applicable to stone mining and crushing and cutting of rocks and concrete. The silent blast spalling device is formed by two memory alloy plates that are fastened symmetrically and pressure transmitting bodies clamped at two sides of the memory alloy plates, wherein the middle part of each memory alloy plate is arc-shaped and two ends thereof are straight and provided with symmetrical grooves; the inner side of each pressure transmitting body is provided with a key groove jogged with the memory alloy plate and the outer side thereof is circular-arc-shaped. After the spalling device is placed in a drill hole, the memory alloy plates are heated so as to lead the shape of the middle arc-shaped part to tend to be straight; and by the pressure transmitting bodies, extruding force is transmitted to the surrounding rocks so as to break the rocks. The spalling device has simple structure, large spalling force, fast rock spalling speed, safe and reliable use and convenient operation, is intelligent and environment-friendly and can be used repeatedly.
Description
Technical field
The utility model relates to a kind of expander, especially a kind of voiceless demolition expander that is applicable to exploitation stone material, rock and concrete cutting fragmentation.
Background technology
In stone mining, rock and concrete cutting fragmentation, the voiceless demolition technology has obtained application more and more widely.Existing voiceless demolition mainly contains high-energy combustion agent and static breaking agent blasting method.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.In addition, the cost of high-energy combustion agent is higher.The static crushing agent method utilizes the cracking agent chemical reaction to produce the expansion fractured rock, but the rock crack time is long, and efficient is low, is subjected to climatic effect obvious, and cost is also higher, and in addition, static breaking agent has corrosivity, needs certain construction protection.Therefore be badly in need of a kind of low cost, safe and reliable, speed of application is fast, and environment and the harmless stone device that splits of personnel are met the demands.
Summary of the invention
The purpose of this utility model is the deficiency that overcomes prior art, provides a kind of simple in structure, low cost, and safe and reliable, speed of application is fast, and the active force harmless to environment and personnel is big, efficient is high and reusable voiceless demolition expander.
Voiceless demolition expander of the present utility model, constitute by two symmetries memorial alloy plate that fastens and the pressure transmission body that is installed on memorial alloy plate both sides, memorial alloy plate middle part is curved, two ends are straight and have symmetrical groove, pressure transmission body inboard has and memorial alloy plate tabling keyway, and its outside is circular arc.
The memorial alloy plate that described symmetry fastens is memory Ti-Ni alloy, iron-based or the copper-based memory alloy with round trip memory function; Described pressure transmission body and function carbide alloy or hard steel are made.
The beneficial effects of the utility model: do not use any chemical material, have safety, noiselessness, shockproof, no slungshot, the no smoke of gunpowder, pollution-free, environmental friendliness, harmless to personnel; Expansion force is big, can be used for exploiting stone material, also can be used for the fracture cutting or the fragmentation of concrete and other fragile materials; Split stone efficient height, cracking time is short; Reusable, cost is low, and is simple in structure, assembles easy to use, reusable.
Description of drawings
Fig. 1 is a structural front view of the present utility model.
Fig. 2 is the structure vertical view of Fig. 1.
Among the figure: 1-memorial alloy plate, 2-pressure transmission body, 3-groove, 4-keyway.
The specific embodiment
Below in conjunction with accompanying drawing an embodiment of the present utility model is further described:
Voiceless demolition expander of the present utility model, constitute by two symmetries memorial alloy plate 1 that fastens and the pressure transmission body 2 that is installed on memorial alloy plate 1 both sides, memorial alloy plate 1 middle part is curved, arc convex is outside, the centre is a through hole, memory Ti-Ni alloy, iron-based or the copper-based memory alloy of memorial alloy plate 1 for having the round trip memory function; Memorial alloy plate 1 two ends are straight and have symmetrical groove 3, pressure transmission body 2 inboards have the keyway 4 with memorial alloy plate 1 tabling, the outside of pressure transmission body 2 is circular arc, processes the length and the radian of arc as required, and pressure transmission body 2 usefulness carbide alloy or hard steel are made.
During use, the expander that assembles is put into rock-boring, in the hole, be blown into hot blast or put into the electric heater heating in two memorial alloy plates, 1 outside, memory alloy material is heated up rapidly, when temperature surpasses the phase transition temperature of material, produce recovery of shape in 1 short time of memorial alloy plate, arch section is tending towards straight in the middle of it, the output bulbs of pressure pass to boring rock on every side by pressure transmission body 2, thereby make rock spalling under pressure.
If carry out the rock cutting, a plurality of expanders are put into wire boring and the energising simultaneously that designs, simultaneously a plurality of memorial alloy plates 1 are heated up, 1 distortion of memorial alloy plate is radially expanded by pressure transmission body 2, the squeezing action that produces passes to rock rapidly, make rock produce fracture and run through destruction, thereby realize the rock cutting along big gun hole line direction.Stop energising after rock cutting is finished, take out expander and treat that next circulation reinstalls use.
Claims (3)
1. voiceless demolition expander, it is characterized in that: memorial alloy plates (1) that it is fastened by two symmetries and pressure transmission body (2) formation that is installed on memorial alloy plate (1) both sides, memorial alloy plate (1) middle part is curved, two ends are straight and have symmetrical groove (3), pressure transmission body (2) inboard has and memorial alloy plate (1) tabling keyway (4), and its outside is circular arc.
2. voiceless demolition according to claim 1 is opened and is split device, it is characterized in that, memory Ti-Ni alloy, iron-based or the copper-based memory alloy of memorial alloy plate (1) for having the round trip memory function that described symmetry fastens.
3. voiceless demolition expander according to claim 1 is characterized in that, described pressure transmission body (2) is made with carbide alloy or hard steel.
