Abstract

The utility model discloses a novel rock and concrete splitter which comprises an oil cylinder, a manual valve, a guide sleeve and an expansion head, wherein the manual valve is mounted on the oil cylinder, the guide sleeve is connected with the lower portion of the oil cylinder, and the expansion head is connected with the lower portion of the guide sleeve. The upper end of the guide sleeve is provided with an external thread and is connected with the oil cylinder in a threaded manner, the lower end of the guide sleeve is connected with an expansion block through a T-shaped clamping groove, hanging shoulders are arranged on the left side and the right side of the T-shaped clamping groove, an upper plane of each hanging shoulder is an inclined plane which is inclined downwards from center to outside, and the included angle A between each inclined plane and a horizontal plane ranges from -1 degree to 10 degrees and optimally ranges from -3 degrees to 6 degrees. When the splitter works, the guide sleeve cannot be snapped, high noise is avoided, and the splitter is small in size, light in weight shock-free in work.

Description

A kind of New Rock and concrete splitter

Technical field

The utility model relates to can use mining, and the concrete in the engineering construction and rock splitter relate in particular to a kind of splitter guide pin bushing cylinder.

Background technology

In the quarrying industry, and steel concrete dismounting field, explosive generally adopted, expansion agent and rope saw and hydraulic breaking hammer etc.

The technology exploitation, these technology are very imperfect, for example: use explosive production dangerous, quarrying stone, out-of-shape, lumber recovery is too low; Use rope to cut to adopt cost too high, can't use in the lack of water place; The expansion agent exploitation can be affected by Changes in weather, and the blast hole success rate is not high, and the reaction time is long, and production efficiency is low; The hydraulic breaking hammer energy consumption is large, can produce larger noise and impact force during work, brings discomfort to the operative employee, exerts an influence to surrounding enviroment.

For the problems referred to above, it is little to have in the market a kind of volume, lightweight, is fit to the manual operation splitter, the common structure of this splitter is as follows, the hand-operated valve on it comprises an oil cylinder and is connected oil cylinder be connected the oil cylinder bottom to connect a guide pin bushing cylinder to be connected a swollen head composition with guide pin bushing cylinder bottom.

During use, the swollen head of splitter is inserted rock and the concrete in pre-drilled hole, open hydraulic power system, open hand-operated direction valve, in-oil cylinder piston is under hydraulic oil promotes, with the axial downward-extension of its piston connecting wedge compressing two ward off piece radially distending press to hole wall, make rock and concrete spalling.

This splitter be with hydraulic oil as energy source, the head of splitter is inserted can be with hundreds of tons rock and concrete division within time several seconds by oil pressure in the rock in pre-drilled hole and the concrete.

This splitter is because volume is little, lightweight, and when work without impact, noiselessness, and the advantage such as economic and practical, oneself is through being widely used in market at present.But also in the part that comes with some shortcomings.

As shown in Figure 1 and Figure 2, at present in the splitter guide pin bushing cylinder 11 and the head that be connected connects by T-shaped draw-in groove 12 but two side suspension shoulders, 13 faces of T-shaped draw-in groove 12 all are same horizontal planes, the splitting effect noise very large with generation when swollen head and guide pin bushing cylinder 11 hang the very large frictional resistance of 13 generations of shoulder and affect splitter and work during splitter work.

The utility model content

The purpose of this utility model is the place that overcomes present splitter guide pin bushing barrel structure deficiency, and a kind of splitter guide pin bushing cylinder of new structure of long service life is provided.

For addressing the above problem, the utility model is realized by following scheme: a kind of New Rock and concrete splitter, comprise oil cylinder and the hand-operated valve that is contained on the oil cylinder, connect a guide pin bushing cylinder with the oil cylinder bottom, and guide pin bushing cylinder bottom connects a swollen head composition, the upper end of described guide pin bushing cylinder is that the band external screw thread is threaded connection with oil cylinder, the lower end of guide pin bushing cylinder is connected with swollen head by T-shaped draw-in groove, this T-shaped draw-in groove the right and left is with hanging shoulder, the upper plane of described suspension shoulder is the outer downward-sloping inclined-plane of direction of mind-set therefrom, and the included angle A of this inclined-plane and horizontal plane is at-1 °--between 10 °.

The included angle A of described inclined-plane and horizontal plane is at-3 °--and be best between 6 °.

The utility model beneficial effect:

1, reduces the frictional resistance that swollen head and guide pin bushing cylinder hang circular bead surface, the disruptive force of increase splitter.

2, reduce the wearing and tearing of hanging circular bead surface;

3, the slip in T-shaped draw-in groove of swollen head is more flexible, reduces the phenomenon that swollen head is stuck at draw-in groove to occur, also the head that expands is played a protective role.

The specific embodiment

Such as Fig. 3, Fig. 4, Fig. 5, shown in Figure 6, a kind of New Rock and concrete splitter, comprise oil cylinder 4 and the hand-operated valve 5 that is contained on the oil cylinder 4, connect a guide pin bushing cylinder 1 with oil cylinder 4 bottoms, and guide pin bushing cylinder 1 bottom connects swollen 6 compositions, the upper end of described guide pin bushing cylinder 1 is that the band external screw thread is threaded connection with oil cylinder 4, the lower end of guide pin bushing cylinder 1 is connected with swollen 6 by T-shaped draw-in groove 2, these T-shaped draw-in groove 2 the right and lefts are with hanging shoulder 3, the upper plane of described suspension shoulder 3 is outer downward-sloping inclined-planes of direction of mind-set therefrom, the included angle A of this inclined-plane and horizontal plane is at-1 °--10 °, the included angle A of described inclined-plane and horizontal plane is at-3 °--is best between 6 °.

During use, swollen 6 with splitter is inserted rock and the concrete in pre-drilled hole, open hydraulic power system, open hand-operated valve 5, piston in the oil cylinder 4 under hydraulic oil promotes, with the axial downward-extension compressing two of its piston connecting wedge ward off piece radially distending press to hole wall, make rock and concrete spalling, as energy source, the swollen head of splitter is inserted can be with hundreds of tons rock and concrete division within time several seconds by oil pressure in the rock in pre-drilled hole and the concrete with hydraulic oil.
