Abstract
The utility model discloses a disassembly device of a hydraulic hammer neck bush. The disassembly device of the hydraulic hammer neck bush comprises a puller, and further comprises the neck bush and a drill rod base. A plurality of grooves are evenly distributed in the end face A where the neck bush is in contact with the drill rod base, and a plurality of threaded holes are evenly distributed in the end face B of the drill rod base. When the disassembly device is used, four threaded supporting rods of the puller are stretched into the threaded holes in the end face B of the drill rod base to be screwed, then three pulling claws are stretched into the drill rod base, after the pulling claws pass the neck bush, the grooves which hook the end face A of the neck bush are stretched under the effect of a spring, then a handle is rotated, and the neck bush is slightly taken out from the drill rod base through a threaded rod. According to the disassembly device, when the neck bush which needs to be replaced is directly taken out from the drill rod base, the neck bush does not need to be damaged, and damage to the drill rod base can not be caused.
Description
Technical field
The utility model relates to the provision for disengagement of hydraulic hammer neck bush, belongs to the mining machinery field.
Background technology
Hydraulic hammer in use because vibration service constantly, the wearing and tearing increasing of its drill steel and drill steel seat neck bush when attrition value acquires a certain degree, need to be carried out dismounting and change to neck bush.Existing neck bush is because end face is smooth plane, it can't be taken out from the drill steel seat, therefore usually adopt following two kinds of methods: 1, chisel is extend in the drill steel seat, knock chisel and then make neck bush destroyed by external force, the neck bush that more renews again after then the neck bush of fragmentation being poured out.This kind method both wasted time and energy, and easily the drill steel seat was caused damage; 2, with the flame gas cutter neck bush is slit into two, three sections, this kind method is destroyed the composition surface of drill steel seat and neck bush easily.
Summary of the invention
Problem to be solved in the utility model provides a kind of provision for disengagement, and the neck bush that it can be changed needs directly takes out from the drill steel seat, and need not to destroy neck bush, also can not cause damage to the drill steel seat.
The provision for disengagement of hydraulic hammer neck bush, it comprises draws horse, it is characterized in that: further comprising neck bush, drill steel seat, is evenly equipped with several grooves at neck bush and the contacted end face A of drill steel seat, is evenly equipped with several screwed holes at the end face B of drill steel seat.
This novel device in use, to draw first four screw thread poles of horse to stretch in the screwed hole on the drill steel seat end face B screws, then three pulling claws are extend in the drill steel seat, after pulling claw passes through neck bush, opening the groove that hooks on the neck bush end face A under the effect of spring, then swing handle slowly takes out neck bush from the drill steel seat by screw rod.When this novel device directly takes out from the drill steel seat at the neck bush that will need to change, need not to destroy neck bush, also can not cause damage to the drill steel seat.It is simple in structure, and is easy to operate.
Description of drawings
Fig. 1 is the structural representation of this novel provision for disengagement.
Fig. 2 is the assembling schematic diagram of neck bush and drill steel seat.
Fig. 3 is the front view of neck bush.
Fig. 4 is the right view of Fig. 3.
Fig. 5 is the left view of drill steel seat.
The specific embodiment
From Fig. 1, Fig. 2, Fig. 3, Fig. 4, Fig. 5 as can be known, this novel provision for disengagement comprises draws horse, it also comprises neck bush 1, drill steel seat 2, is evenly equipped with several grooves 4 at neck bush 1 with drill steel seat 2 contacted end face A, is evenly equipped with several screwed holes 3 at the end face B of drill steel seat 2.Groove 4 on the end face A of neck bush 1 is square groove, and quantity is three.Screwed hole 3 quantity on the end face B of drill steel seat 2 are four.
As can be seen from Figure 1, what the dismounting neck bush was used draws horse, comprise screw thread pole 6, pulling claw 7, handle 8, screw rod 9, spring 10, bracing frame 11, bearing pin 12, fixed mount 5, bracing frame 11, fixed mount 5 all are contained on the screw rod 9 by screw thread, and screw thread pole 6 links to each other with bracing frame 11, pulling claw 7 is hinged by bearing pin 12 and fixed mount 5, simultaneously pulling claw 7 is connected with fixed mount 5 by spring 10, like this, and when pulling claw 7 is stressed, bearing pin 12 rotates, and pulling claw 7 moves to fixed mount 5 directions; When power disappears, in the effect of spring 10, bearing pin 12 counter-rotation, pulling claw 7 is away from fixed mount 5.
When using this novel device dismounting neck bush 1, first four screw thread poles 6 are stretched in the screwed hole 3 on the drill steel seat 2 end face B and screwed, then three pulling claws 7 are extend in the drill steel seat 2, after pulling claw 7 passes through neck bush 1, opening the groove 4 that hooks on the neck bush 1 end face A under the effect of spring 10, then swing handle 8, by screw rod 9 neck bush 1 slowly taken out from drill steel seat 2.
Claims (3)
1. the provision for disengagement of hydraulic hammer neck bush, it comprises draws horse, it is characterized in that: further comprising neck bush (1), drill steel seat (2), be evenly equipped with several grooves (4) at neck bush (1) with the contacted end face A of drill steel seat (2), be evenly equipped with several screwed holes (3) at the end face B of drill steel seat (2).
2. provision for disengagement according to claim 1 is characterized in that: the groove (4) on the end face A of described neck bush (1) is square groove, and quantity is three.
3. provision for disengagement according to claim 1 is characterized in that: screwed hole (3) quantity on the end face B of described drill steel seat (2) is four.
