Problems solved by technology

[0002] The traditional hammer power uses compressed air or steam. Due to the large compressed air or steam transmission pipeline, there is a large amount of leakage, and the energy profit margin is very low. At the same time, a large amount of waste gas or waste water is discharged during the working process, which pollutes the environment; in addition The traditional linkage of th...

Abstract

The invention d relates to a hydraulic counterblow hammer. The hydraulic linkage hydraulic counterblow hammer comprises a linkage oil cylinder, a hydraulic double-linkage oil cylinder, a lower hammer, an upper hammer, a hammer support, hydraulic power and a hydraulic control system; the lower hammer and the upper hammer are installed inside the hammer support; the lower hammer and the upper hammer are in linkage through an all hydraulic power driving system; the hammer support is used for guiding when the lower hammer and the upper hammer move; the hydraulic linkage oil cylinder and the hydraulic double-linkage oil cylinder are installed on a hammer support base; the hydraulic power and the hydraulic control system are installed at the top of the hammer support. The hydraulic linkage hydraulic counterblow hammer is characterized by also comprising compression resistance devices and protective sleeves; the compression resistance devices are arranged inside the lower hammer and the upper hammer; the protective sleeves are arranged on external sides of piston rods of the hydraulic linkage oil cylinder and the hydraulic double-linkage oil cylinder to protect the piston rods of the hydraulic linkage oil cylinder and the hydraulic double-linkage oil cylinder. The hydraulic linkage hydraulic counterblow hammer has the advantages of shortening the length of oil paths, improving the utilization rate of energy, being rapid in response speed, prolonging the service life of the hammers and being long in using time, safe and rapid in utilization.

Example Embodiment

[0010] see figure 1 , this specific embodiment adopts the following technical scheme: it comprises hydraulic linkage oil cylinder 1, hydraulic double linkage oil cylinder 2, lower hammer head 3, upper hammer head 4, hammer frame 5, hydraulic power and hydraulic control system 6, lower hammer head 3, The upper hammer head 4 is installed in the hammer frame 5. The linkage between the lower hammer head 3 and the upper hammer head 4 adopts a full hydraulic power drive system, which is guided by the hammer frame 5 during movement. The hydraulic linkage cylinder 1 and the hydraulic double linkage cylinder 2 are installed separately. On the base of the hammer frame 5 , the hydraulic power and hydraulic control system 6 is installed on the top of the hammer frame 5 , and it also includes a compression device 7 and a protective sleeve 8 , and the compression device 7 is respectively arranged in the lower hammer head 3 and the upper hammer head 4 . The protective sleeves 8 are respectively arranged on the outside of the piston rods of the hydraulic linkage cylinder 1 and the hydraulic double linkage cylinder 2 to protect the piston rods of the hydraulic linkage cylinder 1 and the hydraulic double linkage cylinder 2 .
[0011] Hydraulic linkage cylinder 1 and hydraulic double linkage cylinder 2 have the same area to realize equal-stroke telecontrol.
[0012] The pressure-resisting device 7 and the hammer head are formed by die casting at one time.
[0013] The working principle of this specific embodiment is: when the first solenoid valve Y1 and the second solenoid valve Y2 are energized, the upper and lower cavities of the driving oil cylinder are both fed with high-pressure oil, and the lower hammer head 3 and the upper hammer head 4 are driven differentially. The counterattack is realized under the action of the hydraulic linkage cylinder 1 and the hydraulic double linkage cylinder 2. When the first solenoid valve Y1 loses power, the high-pressure oil in the upper chamber of the driving cylinder returns to the fuel tank through the first solenoid valve Y1 and the fourth solenoid valve Y4. , to realize the return of the upper and lower hammer heads. When the third solenoid valve Y3 and the fourth solenoid valve Y4 are energized, the lower hammer head 3 and the upper hammer head 4 are slowly raised through the φ3 damping hole.
[0014] In the present invention, the impact force of the lower hammer head 3 and the upper hammer head 4 is buffered by the anti-compression device 7, the service life of the lower hammer head 3 and the upper hammer head 4 is prolonged, and the hydraulic linkage oil cylinder 1 and the hydraulic double linkage oil cylinder 2 are protected by the protective sleeve 8 , reducing the number of maintenance and prolonging the use time.
[0015] The invention shortens the length of the oil circuit, improves the utilization rate of energy, has fast response speed, prolongs the service life of the hammer head, has long service time, and is safe and fast to use.
