AI Technical Summary

Problems solved by technology

[0004] The above-mentioned existing technical solutions have the following defects: although the above-mentioned hydraulic breaker has a good cushioning effect, the above-mentioned hydraulic breaker will vibrate during the working process, and the rear cylinder and the middle cylinder are fastened through bolts and nuts. Together, due to the vibration of the above-mentioned hydraulic breaker, the bolts will rotate, and the rear bar body will move on the bolts, causing the rear cylinder body to loosen, thereby causing mechanical accidents or safety accidents

Embodiment 1

[0034] refer to figure 1 and figure 2 , is a breaker bolt anti-loosening mechanism disclosed in the present invention, including a connecting plate 2, a rear cylinder 1 is placed on one side of the connecting plate 2, the rear cylinder 1 and the connecting plate 2 are in the shape of a cuboid, and the rear cylinder 1 It is fixedly connected with the connection plate 2, and one side of the rear cylinder body 1 is provided with four connection holes 11 through the rear cylinder body 1, and the four connection holes 11 are evenly distributed at the four corners of the rear cylinder body 1 side . The connection plate 2 is provided with four connection holes 21 that run through the connection plate 2. The inner sidewall of the connection hole 21 is tapered. The connection hole 11 is directly opposite to the connection hole 21 and communicates with each other. A bolt 3 is provided, and the bolt 3 protrudes from the second connecting hole 21 and is threadedly connected with a nut ...

Embodiment 2

[0039] The difference between the second embodiment and the first embodiment is that, referring to image 3 and Figure 4 An annular ratchet 8 is fixed at one end of the nut 4 close to the connecting plate 2 , and the outer diameter of the ratchet 8 is larger than that of the washer 17 . The connecting plate 2 is slidably connected with a pawl 9 placed on one side of the ratchet 8. The plane where the ratchet 8 is located is perpendicular to the plane where the ratchet 9 is located. The end of the ratchet 9 away from the ratchet 8 is provided with a spring 10. Push the ratchet 9 toward the direction of the ratchet 8, so that the ratchet 8 and the ratchet 9 cooperate with each other, and then the nut 4 can only rotate in the direction of locking. When the bolt 3 is fixed, the nut 4 can be prevented from loosening.

[0040] refer to image 3 and Figure 4 , the connecting plate 2 is slidably connected with a depression rod 13, and one end of the depression rod 13 extends out o...

Abstract

The invention relates to a breaking hammer bolt anti-loosening mechanism, and belongs to the technical field of breaking hammers. The breaking hammer bolt anti-loosening mechanism comprises bolts, nuts and a connecting plate; a rear cylinder body is fixedly connected with the connecting plate, connecting holes I are formed in the rear cylinder body, connecting holes II are formed in the connectingplate, the connecting holes I directly face the connecting holes II, the bolts penetrate through the connecting holes I and the connecting holes II to be in threaded connection with the nuts, and thebolts are sleeved with fastening rings, each fastening ring is provided with a fracture, the nuts are tightened on the bolts and press the fastening rings toward the connecting holes II, and the locking force between the connecting plate and the bolts is increased while the fastening rings contract. The breaking hammer bolt anti-loosening mechanism has the effect of preventing the bolts from loosening.

Description

technical field [0001] The invention relates to the technical field of breakers, in particular to a breaker bolt anti-loosening mechanism. Background technique [0002] The breaker is driven by hydrostatic pressure to drive the piston to reciprocate. When the piston strokes, it hits the drill rod at high speed, and the drill rod breaks solids such as ore and concrete. The power source of the breaker is the pressure oil provided by the pump station of the excavator or loader, which can more effectively clean up the floating stones and the soil in the rock gaps during the excavation of the building foundation. [0003] Existing notification number is that the Chinese patent of CN206829228U discloses hydraulic breaker, comprises cylinder body, valve body, drill rod and piston, and piston fits in cylinder body, and drill rod cooperates with piston, and valve body is fixed on the cylinder body, and cylinder body The body includes a front cylinder, a middle cylinder and a rear cy...
