The specific embodiment
Below in conjunction with accompanying drawing, the present invention will be described in detail, so that technical solution of the present invention is easier to understand, grasp.
Shown in Fig. 1-5, the pneumatic hammer of tonifying Qi continuously of the present invention, comprise connecting rod (1), be located at the outside piston helical pitch (2) of connecting rod (1), be located at piston rod portion tonifying Qi hole (3) of piston helical pitch (2) top, be located at the piston cavity of resorption (4) of piston rod portion tonifying Qi hole (3) top, be located at the inner piston (5) of piston helical pitch (2), be located at the piston upper chamber (6) of piston cavity of resorption (4) top, be located at the last valve (7) on pneumatic hammer top, be located at the hammer stem epicoele (8) of valve (7) one sides, be located at the waste gas chamber (9) of valve (7) below, be located at the middle air cavity (10) of below, waste gas chamber (9), be located at the following valve (11) of middle air cavity (10) below, be located at the hammer stem (13) of hammer stem epicoele (8) lower inner, be located at the hammer stem cavity of resorption (12) of hammer stem (13) below, be located at the middle valve (14) of middle air cavity (10) one sides, be located at the check-valves downtake (15) of middle air cavity (10) opposite side, non-return valve pocket (16), check-valves (17) and first spring (18), be located at air flue (19) on the check-valves of waste gas chamber (9) one sides and be located at middle valve master mouth (20) on the middle valve (14), valve (14) is provided with check valve (22) in described, and described check valve (22) is provided with check valve gas supplementing opening (21), second spring (23) and spring base (24).When connecting rod (1) drive piston (5) is up, valve master mouth (20) during middle valve (14) is rotated counterclockwise and cuts out, middle valve (14), check-valves (17), middle valve master mouth (20) all is in closed condition, check valve gas supplementing opening this moment (21) is in the position with atmosphere UNICOM, when piston (5) is up to top dead-centre by bottom dead centre, piston cavity of resorption (4) forms negative pressure, under the effect of atmospheric pressure, air overcomes the active force of second spring (23), push check valve (22) open, air is through check valve gas supplementing opening (21), middle air cavity (10), following valve (11) enters piston (4) cavity of resorption and realizes tonifying Qi.Be to keep negative pressure suspending hammer function, when hitting action, middle valve (14) be rotated counterclockwise again to check valve gas supplementing opening (21) for till the closed state.
The sealing surface of described check valve (22) be conical, form sealing with the interior actinal surface of check valve gas supplementing opening (21).
One end of described second spring (23) contacts with check valve (22), the other end contacts with spring base (24), is used for resetting of check valve (22).
Described spring base (24) is fixing with middle valve (14), is used for bearing spring force, reaches the motion guide that is used for check valve (22).
Operation principle of the present invention is:
1) puies forward the hammer principle: as shown in Figure 1, it is descending that connecting rod (1) drives piston (5), the gas warp of piston cavity of resorption (4) valve (11) down enters middle air cavity (10), as shown in Figure 3, because middle valve (14), middle valve master mouth (20) is in closed condition, as shown in Figure 2, enter the gas of middle air cavity (10) under pressure, overcome the active force of first spring (18), push check-valves (17) open, enter non-return valve pocket (16), as shown in Figure 4, because air flue (19) is sealed by last valve (7) on the check-valves, gas is forced into check-valves downtake (15), valve (11) under the warp enters hammer stem cavity of resorption (12) again, thereby realizes carrying hammer.
2) press principle: go up valve (7) and following valve (11) clockwise direction and rotate 45 degree simultaneously, as shown in Figure 1, it is descending that connecting rod (1) drives piston (5), the gas warp of piston cavity of resorption (4) valve (11) down enters middle air cavity (10), as shown in Figure 3, because middle valve (14), middle valve master mouth (20) is in closed condition, as shown in Figure 2, enter the gas of middle air cavity (10) under pressure, overcome the active force of first spring (18), push check-valves (17) open, enter non-return valve pocket (16), as shown in Figure 4, because check-valves downtake (15) is descended valve (11) sealing, gas is forced into air flue on the check-valves (19), again through last valve (7), enter hammer stem epicoele (8), thereby realize pressing.
Carrying hammer and pressing in these two actions, as shown in Figure 1, it is up that connecting rod (1) drives piston (5), be connected air flue with piston cavity of resorption (4), as shown in Figure 3, valve master mouth (20) during middle valve (14) is rotated counterclockwise and cuts out, middle valve (14), check-valves (17), middle valve master mouth (20) all is in closed condition, because middle valve (14) has installed check valve gas supplementing opening (21) additional, check valve (22), second spring (23), spring base (24), check valve gas supplementing opening (21) is in the position with atmosphere UNICOM, when piston (5) is up to top dead-centre by bottom dead centre, piston cavity of resorption (4) forms negative pressure, under the effect of atmospheric pressure, air overcomes the active force of second spring (23), push check valve (22) open, air is through check valve gas supplementing opening (21), middle air cavity (10), following valve (11) enters piston cavity of resorption (4) and realizes tonifying Qi.
Be to keep the negative pressure suspending hammer function in the operation principle, when hitting action, the middle valve (14) after the improvement on the basis, position of Fig. 3, be rotated counterclockwise again to check valve gas supplementing opening (21) for till the closed state.
According to the contrast before and after the invention process, pneumatic hammer is put forward the measurement data of hammer, push action motor current, and former average electric current is near the motor rated current before implementing, and its average current all drops to original 10% after the enforcement.
Example C41-1000KG pneumatic hammer power of motor 75Kw carries hammer, push action time and accounts for 6% of average service time of every day pneumatic hammer 7 hours average service time of every day, but saves energy 75*7* (1-10%) * 6%=28.35Kwh then.
Little pneumatic hammer is disregarded, China every day with the C41-1000KG pneumatic hammer by 1000, but all implement the energy 28.35Kwh*1000=28350 Kwh that save every day behind this patent.
Should be noted that at last that obviously those skilled in the art can carry out various changes and distortion to this patent and not break away from the spirit and scope of the present invention.Like this, if these modifications of this patent and distortion belong within the scope of this patent claim and equivalent technologies thereof, then this patent also is intended to comprise these changes and distortion.
