Problems solved by technology
However, when an ordinary breaker is equipped with an ordinary excavator, the pre-pressing pressure and position adjustment of the breaker are all carried out through the arm cylinder.
When striking downwards, under the action of the self-weight of the breaker, drill rod, bucket rod, moving rod, etc., the pre-jacking pressure and position adjustment requirements are basically the same, and the striking effect is better; while striking horizontally and upwards, due to the loss of self-weight Function, pre-jacking pressure and position adjustment requirements are not consistent, mainly because the pre-jacking pressure is insufficient. During use, the breaking hammer will work well when it hits downwards, but when the drill rod is horizontal and hits upwards, the breaking hammer will not vibrate. , The phenomenon of not being able to impact normally seriously reduces the work efficiency and affects the application expansion of the breaker, especially in the application of roadway breaking loose layer cleaning and building demolition.

Embodiment Construction
[0022] Examples, see e.g. Figure 1 to Figure 5 As shown, a hydraulic breaker with hydraulic support includes a hammer shell 12 fixed on a flange 11, a hammer body 13 is sleeved in the hammer shell 12, and a steel drill 14 is connected to the right end of the hammer body 13. The drill 14 extends out of the hammer shell 12, and a hydraulic support mechanism is provided between the hammer shell 12 and the hammer body 13;
[0023] The hydraulic support mechanism includes a pair of clamping seats 2 arranged left and right. The two clamping seats 2 are respectively inserted and fixed on the left end and the right end of the hammer body 13. On the two slide rails 3, the right end of the slide rail 3 is provided with a baffle plate 4, and the two slide rails 3 and the baffle plate 4 are fixed on the inner wall of the hammer shell 12; the left end of the hammer shell 12 is provided with a boss 121, the convex There is a gap between the left end surface of the platform 121 and the fla...

The invention discloses a hydraulic breaking hammer with hydraulic support. The breaking hammer comprises a hammer shell and a hammer body, and a hydraulic supporting mechanism is arranged between thehammer shell and the hammer body. The hydraulic supporting mechanism comprises a pair of clamping bases which is arranged left and right and is used for fixing the hammer body. The two clamping basesare connected to a sliding rail in a sliding mode, a baffle is arranged at a right end of the sliding rail, a top rod is fixed to the clamping base at a left end, and the top rod is provided with thehydraulic support. Through the hydraulic supporting mechanism, the breaking hammer can always keep normal oscillation starting and an excellent impact effect in a striking and breaking process in alldirections.
Description
technical field [0001] The invention relates to the technical field of breaking hammers, in particular to a hydraulic breaking hammer provided with a hydraulic support. Background technique [0002] With its advantages of large impact energy, fast frequency and high construction efficiency, hydraulic breakers are more and more used in mining, road breaking, tunneling, building demolition, etc. However, when an ordinary breaker is equipped on an existing common excavator, the pre-jacking pressure and position adjustment of the breaker are all carried out through the stick oil cylinder. When striking downwards, under the action of the self-weight of the breaker, drill rod, bucket rod, moving rod, etc., the pre-jacking pressure and position adjustment requirements are basically the same, and the striking effect is better; while striking horizontally and upwards, due to the loss of self-weight Function, pre-jacking pressure and position adjustment requirements are not consisten...
