For achieving the above object, the utility model is realized by following scheme.Lining remover comprises cylinder body, piston, clack box, distributing valve, auxiliary valve, gas circuit, drilling tool.A piston moving up and down is arranged in cylinder body, and cylinder body one end is established drilling tool, and the other end is established clack box, is provided with a distributing valve moving up and down in clack box, establishes an auxiliary valve movably in distributing valve upper end.Establish a plurality of air admission holes and steam vent on cylinder body and clack box, its design feature is respectively to establish an auxiliary exhaust ports at the cup of cylinder body and chamber, back, makes stroke auxiliary exhaust ports and return air admission hole separate.The back pressure cavity that forms in motion process of piston all has independently auxiliary exhaust duct like this, and effective merit is strengthened.
The utility model can also be realized by following measure.Piston and drilling tool are made slender type, the stress transmission that is beneficial to clash into, the scraping mechanism that the friction pair that constitutes between cylinder body and piston, clack box and distributing valve, valve gap and the auxiliary valve adopts soft to match.Can simplify technology, reduce cost.It is whole that cup auxiliary exhaust hole site is adjustable.To realize the optimal combination of impact energy, frequency of impact.
The utility model compared with prior art has following advantage and effect.
1, owing to structurally have dual auxiliary exhaust system, makes the back pressure resistance of stroke, return little, increased the impact end speed and the frequency of impact of piston;
2, because piston stroke is big, fully work done of compressed air, the thermal efficiency height of machine;
3, because stroke auxiliary exhaust ports and return air admission hole are separate, the gas shock when having stopped the valve commutation in the gas circuit, and can make cup be formed for the air cushion of return starting in advance;
4, can realize the optimum combination of impact energy, frequency of impact by adjusting the position of auxiliary exhaust ports;
5, the utilization rate of calming the anger is higher, and pressure at expulsion reduces, thereby noise is low, the vibration is little;
6, the friction pair in the lining remover is implemented soft and is cooperated mechanism under the prerequisite that guarantees parts life-span, can simplify technology, reduce cost.
Embodiment is further described the utility model below in conjunction with accompanying drawing.
The lining remover structural representation that Fig. 1 provides for the utility model.
As can be seen from the figure, lining remover is made up of cylinder body, piston, clack box, distributing valve, auxiliary valve, gas circuit, drilling tool.Establish slender type piston 6 in the cylinder body 5, piston and drilling tool are made elongated shape, the stress transmission that is beneficial to clash into, an end of cylinder body is connected with slender type drill steel 9, and the other end is connected with clack box 2, establishing air valve 3 in the clack box, establish auxiliary valve 1 in the upper end of distributing valve, piston forms chamber 4, back with cylinder body, distributing valve in cylinder body, and piston and cylinder body, drilling tool form cup 7, be provided with a plurality of air admission holes, steam vent and duct on cylinder body and clack box, these ducts constitute gas circuit 8.It is whole that cup auxiliary exhaust hole site is adjustable.To realize the optimum combination of impact energy, frequency of impact.The friction pair that constitutes between cylinder body and piston, clack box and distributing valve, valve gap and the auxiliary valve, the scraping mechanism that adopts soft to match.Can simplify technology like this, reduce cost.
During lining remover work, piston 6 and distributing valve 3 all have definite relative position.When piston is done the return motion, the cup 7 of cylinder 5 17 communicates with the hole 14 of calming the anger through the hole, back chamber 4 through after chamber steam vent 11 communicate with atmosphere, when piston 6 move upward close the back chamber 4 steam vent 11 time, the auxiliary exhaust ports 13 of back chamber 4 reduces the back pressure of chamber, back, therefore, piston has bigger return speed.The auxiliary exhaust ports of back chamber close air feed early than the chamber, back, make the chamber, back set up back pressure before the stroke in beginning, for stroke is prepared, thereby guarantee that stroke has higher starting acceleration.The moment that return will finish, cup 7 is opened cup air discharge cook 10 and is in dynamic pressure, and this moment, the upper end passing hole channel 16 of distributing valve was bordering on the dynamic pressure state with air discharge cook 10, and the lower end is in the static pressure state, distributing valve moves upward, and this moment, distributing valve and piston all were in the stroke initial state.
