Description

. The invention relates to mining equipment that implements the destruction of strong rocks, and can be used to crush oversize, split block, concrete foundations, etc.

The purpose of the invention is to increase the efficiency of destruction by increasing the reliability of fixing the position of the sliding cheeks in the hole of the object being destroyed.

FIG. Fig. 1 shows the device, the longitudinal cheeks 5 and resting in their front part of the yoke 7. At the time of the location of the radial holes 10 with the clamps 11 opposite the inner groove 8 of the outer yoke 7, the sleeve unlocks and it is under the action of springs b, the rigidity of which is greater than the stiffness of the return springs 13, moves in the direction of the shank 2 of the wedge 1, thereby allowing the latter under the action of the shock

cheeks 5 under the action of the spring 13 returns to its original position. In this case the clamps 11 fall into the grooves 12, the yoke 7 is displaced by the composite abutment flange 14 until it is not cut; in fig. 2 - section AA of the load to carry out further movement.

the firm inside the hole is relatively stationary. The device contains a shock wedge 1, 5 cheeks, making them wedging ,,

made in the form of a rod having needles, which leads to the required destruction,

At the time of axial movement of the cutting movement of the outer cage 7 top-pressing sleeve 9, in the radial hole the balls of the stoppers 11 fall into pieces 10 of which hardware clamps 11, the bore hole 10, where and made - made, nap An example, in the form of balls, is their locking with the inner surface held in the grooves 12, which are available on the arms 7.

Claims (1)

Invention Formula 14 to the ends of the sleeve 9, and the holder 7 is five to seven times less than the spring stiffness, a device for breaking solid objects including sliding cheeks, a shock wedge installed between the disintegrating cheeks for 5 s. sleeve 9 movable-35 movable cheeks, pressure sleeve, stopper assembly. In addition, in planes axially mounted on the impact wedge of the junction of the component parts of the split sleeve 9 over the ends of the cheeks and spring-loaded, there are grooves in which the wedge is installed on the side opposite to the pins 15. The sliding device operates as follows in a way. clamping sleeve with cheeks, different When lowering the device into the cavity 40 in order to increase the efficiency of the pre-drilled hole 1, the chains 5 are moved along the walls of the hole until they press their conical surfaces into its mouth with their conical surfaces. After organizing multiple shock loads at the end of the shank 2 of the wedge 1, the cheeks 5 are more densely pressed to the hole of the cheeks 5 by springs 6 compressed by the sleeve 9, which moves along with the wedge 1, because in the initial moments 45 destruction by increasing the reliability of fixing the position of the sliding cheeks in the hole of the object to be destroyed, the device is equipped with a tubular holder covering the clamping sleeve in friction engagement with it and installed with the possibility of an emphasis on the ends of the sliding cheeks with the ball clamps of the clamping sleeve on the impact wedge, connection is made in Neither the position of the movable stop assembly from the compression spring installed in the pipe wedge 1 is fixed. The subsequent movement of the wedge 1 together with the sleeve 9 and the retainers 11 located therein, carried out as a result of the blows struck on its shank 2, occurs relative to the already fixed The cage and on the inner surface of the latter are made sockets for withdrawing the ball clamps of the clamping sleeve from engagement with the impact wedge at the end of the stroke of the clamping sleeve towards the sliding cheeks. the insert cheeks 5 and the cage 7 resting in their face part 7. At the moment of the location of the radial holes 10 with the clamps 11 opposite the inner groove 8 of the outer casing 7, the sleeve unlocks and under the action of the springs b, the stiffness of which is greater than the return spring 13, moves into the direction of the shank 2 of the wedge 1, thereby allowing the latter under the action of the shock  loads further move cheeks 5 under the action of the spring 13 returns to its original position. In this case, the clamps 11 fall into the grooves 12, the yoke 7 is displaced by the composite abutment flange 14 until it collapses the movable locking assembly along with - O.l g, fr, inm 14 nt- At the time of movement of the outer cage 7, the upper balls of the stoppers 11 fall into the radial holes 10, where they are locked by the inner surface of the cage 7. At the same time, it will be fixed in the end of the split bushing 9 During the movement of the outer cage 7, the upper balls of the stoppers 11 fall into the radial holes 10, where they are locked with the inner surface of the cage 7. At the same time, the position of the nnuM / u.-mnnnunm uchpch ich nmpgk is fixed. the movement of the movable stopper node and interrelated with they insert members 5 on the wedge 1, v. e. all driven device to its original position. thirty Invention Formula  bushing with cheeks, characterized by 40 in order to increase the destruction by increasing the reliability of fixing the position of the sliding cheeks in the hole of the object to be destroyed, the device is equipped with a tubular holder covering the clamping sleeve in friction engagement with it and installed with the possibility of an emphasis on the ends of the sliding cheeks with the ball clamps of the clamping sleeve on the impact wedge, connection is made in  The compression spring installed in the pipe is a compression spring installed in the tubular holder, and on the inner surface of the latter there are slots for withdrawing the ball clamps of the clamping sleeve from the engagement with the impact wedge at the end of the stroke of the clamping sleeve towards the sliding cheeks.
