Breaking hammer hydraulic oil pipe connecting mechanism

Abstract

The invention relates to the technical field of breaking hammers, and discloses a breaking hammer hydraulic oil pipe connecting mechanism. The connecting mechanism comprises a hammer body, wherein anoil injection channel is fixedly formed in the side wall of the hammer body, a vertical rod is connected to the inner wall of the oil injection channel, a fixing rod is fixedly connected to the middleof the vertical rod, a hollow ball head is rotatably connected to the portion, extending out of the oil injection channel, of the fixing rod, the ball head is provided with an oil cavity and is connected with an oil inlet pipe, the oil inlet pipe penetrates through the ball head and extends into the oil cavity, and the end, away from the oil injection channel, of the fixing rod is in threaded connection with a limiting ring. When the breaking hammer is used for operation, the hammer body drives the oil inlet pipe to move when vibrating and shaking are generated, the oil inlet pipe drives theball head to rotate around the fixing rod, the ball head has a buffering effect, a part of stress borne by the oil inlet pipe is relieved, acting force borne by an end opening of the oil inlet pipe isreduced, the oil inlet pipe is not directly connected with the oil injection channel, stress loads borne by the oil inlet pipe are small, and it is guaranteed that the oil inlet pipe is not prone tobreakage.

Description

technical field [0001] The invention relates to the technical field of breaking hammers, in particular to a hydraulic oil pipe connection mechanism of a breaking hammer. Background technique [0002] At present, in the field of construction, the hydraulic breaker has become an important working tool of the hydraulic excavator, and the hydraulic breaker is also installed on the backhoe loader or wheel loader for crushing operations. The power source of the hydraulic 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. During the use of the breaker, it is necessary to continuously inject hydraulic oil into the breaker to ensure the continuous operation of the breaker. [0003] The Chinese patent whose publication number is CN108979524A discloses a new type of rotary drilling rig, including a traveling mechanism...

AI Technical Summary

Problems solved by technology

[0004] The above existing technical solutions have the following defects: when the hydraulic breaker is in use, the oil inlet pipe communicates with the oil discharge port of the hydraulic breaker, and the breaker will vibrate and shake strongly when it is working, The stress load at the place is relatively large, and it is prone to breakage, which affects the normal operation of the breaker.
