Abstract
A wedge block group of a hydraulic rock and concrete splitter comprises a hydraulic cylinder, a piston rod connected with the hydraulic cylinder, a middle wedge block connected with the piston rod, and two symmetrical side wedge blocks matched with the middle wedge block, and is characterized in that chutes are arranged on two side wedge blocks, the shape, width, depth and gradient of the chutes of the side wedge blocks are matched with the overall size of the middle wedge block, so that the middle wedge block can slide in the chutes of the side wedge block. The wedge block group has the benefits that the drilled hole in advance is shallow, so that the energy consumption of drilling equipment can be saved, and the efficiency is improved; the sharp part can not stretch out between the two side wedge blocks and can not collide with the bottom of rock or a concrete hole so as to avoid rupture when the middle wedge block moves to the end; and the stroke of the middle wedge block is shorter, the length of the cylinder and the piston is shortened correspondingly, the materials are few, the weight is greatly lightened, and the cost is low.
Description
Technical field
The utility model relates to a kind of hydraulic pressure rock concrete splitting machine, relates in particular to voussoir group in this hydraulic pressure rock concrete splitting machine.
Background technology
Various rock and ores and concrete all have very high compression strength, but its tensile strength is less, and hydraulic pressure rock concrete splitting machine is exactly the characteristics that are fragility according to rock and concrete, utilizes wedge principle design.
Hydraulic pressure rock concrete splitting machine mainly is made up of Hydraulic Station and splitting rifle two large divisions, when the center chock of the hydraulic oil promotion splitting rifle of Hydraulic Station output is proal, the side voussoir is strutted to both sides, produce huge splitting power, the object for the treatment of splitting was split by predetermined direction in very short time.
The main application scenario of hydraulic pressure rock concrete splitting machine has: the exploitation of various building stones, rock, concrete demolition reduction in the construction occasion, large rock mass, ore, concrete secondary splitting, the application of rescue and relief work and other special construction occasions.
As seen from Figure 1: the piston rod 1 that is connected with hydraulic cylinder in the prior art; The center chock 2 that piston rod 1 connects; The side voussoir 3 of two symmetries that cooperatively interact with center chock 2, the mating surface of center chock and side voussoir is a tapered plane.
The defective of voussoir group in the prior art: the stroke of center chock is longer, causes oil cylinder and piston rod length long, and material is many, Heavy Weight, cost height; Center chock is stretched out from the voussoir of both sides, needs boring in advance darker; The tip of the center chock of stretching out is run into the bottom of rock or concrete hole easily, causes fracture.
Summary of the invention
The utility model technical issues that need to address have provided a kind of hydraulic pressure rock concrete splitting machine voussoir group, are intended to solve the above problems.
In order to solve the problems of the technologies described above, the utility model is achieved through the following technical solutions:
The utility model comprises: the piston rod that is connected with hydraulic cylinder; Described piston rod connects the upper end of center chock; In the both sides of center chock is the side voussoir that cooperates with center chock; Described side voussoir upper end links together with retainer; Have skewed slot on the both sides voussoir that cooperates with center chock, center chock slides in side voussoir skewed slot.
Compared with prior art, the beneficial effects of the utility model are: it is shallow 1, to hole in advance, save the rig energy consumption, raise the efficiency 2, center chock move to the end time tip can in the middle of the voussoir of both sides, not stretch out, can not run into the bottom of rock or concrete hole and cause the stroke of fracture 3, center chock shorter, corresponding oil cylinder and piston rod length shorten, and material is few, weight alleviates greatly, and cost is low.
Description of drawings
Fig. 1 is the structural representation of voussoir group in the prior art;
Fig. 2 is the structural representation of the utility model voussoir group.
The specific embodiment
Below in conjunction with the accompanying drawing and the specific embodiment the utility model is described in further detail:
As seen from Figure 2, the utility model comprises: the piston rod 4 that is connected with hydraulic cylinder; The center chock 5 that is connected with described piston rod 4; The side voussoir 6 of two symmetries that cooperatively interact with described center chock 5; Described both sides voussoir 6 with the center chock mating surface on have skewed slot, the shape of skewed slot, width, the degree of depth and the gradient all cooperate with the appearance and size of center chock, so that center chock slides in skewed slot.
The common elements of the utility model structure and existing structure has piston rod, side voussoir and center chock.But the utility model be characterised in that the side voussoir with the center chock mating surface on have skewed slot.
Voussoir seesawed during the piston rod of hydraulic cylinder of the present utility model promoted, when central voussoir is proal,, can promotes the side voussoir and move to both sides because center chock cooperates with the inclined-plane of side voussoir, produce huge motive force, reach the effect of division object.
Claims (2)
1. a hydraulic pressure rock concrete splitting machine voussoir group comprises: hydraulic cylinder; The piston rod that is connected with hydraulic cylinder; The center chock that is connected with described piston rod; The side voussoir of two symmetries that cooperatively interact with described center chock; It is characterized in that: on the face that matches with center chock of described both sides voussoir, have skewed slot.
2. hydraulic pressure rock concrete splitting machine voussoir group according to claim 1, it is characterized in that: the shape of described skewed slot, width, the degree of depth and the gradient all cooperate with the appearance and size of center chock, so that center chock slides in skewed slot.
