Abstract
The invention provides a hydraulic breaking hammer assembly, comprising a hydraulic driver, an energy accumulator, a brazing rod seat assembly, a through bolt, a case body and a case body tension bolt, wherein the through bolt connects and tightens the driver, the energy accumulator and the brazing rod seat assembly into a breaking hammer body, and the case body and a body are tensioned and connected together by means of the case body tension bolt; and the brazing rod seat assembly is provided with a concave dual-retaining groove; a convex dual-retaining clamping plate is arranged at a connecting and fixing part of the case body and the brazing rod seat of the body; and the convex dual-retaining clamping plate is matched with the concave dual-retaining groove. In the invention, the body can be continuously tensioned by means of the tension bolt and the dual-retainingclamping plate of the case body, so that connection between the case body and the body in the real sense is realized, and the fatigue fracture of the through bolt in the operation process of the breaking hammer and the risk that the brazing rod seat is pulled to be broken due to the impact of a brazing rod and a flat locking pin are reduced; therefore, the service life of the breaking hammer is prolonged, and the economic benefit is increased.
Description
Technical field
The present invention relates to a kind of hydraulic breaking hammer assembly, particularly a kind of equipment that can prevent of full connection shape shakes the disconnected hydraulic breaking hammer assembly that passes through body bolt and drill steel seat when operating at full capacity.
Background technology
Hydraulic breaking hammer comprises hydraulic unit driver A, accumulator B, drill steel seat assembly C, passes through body bolt D, connecting plate (being shell body) E and shell body turnbuckle F six parts formation is installed, the hydraulic breaking hammer assembly of prior art is connected driver A, accumulator B and is strained to as a whole (abbreviation body) by passing through body bolt D earlier with drill steel seat assembly C, and then link by shell body turnbuckle tension with body by shell body, form a quartering hammer assembly.
The quartering hammer assembly of prior art as shown in Figure 1 to Figure 3, only play between body and shell body are mutual and support and supported function, shell body is incorporated into by male cleat 2 and reserves good in the spill screens groove 1 of body drill steel seat assembly both sides body being supported in the shell body, and reserved shell body be connected with excavator working hole be connected with excavator the back just can carry out work by excavator driver's operation quartering hammer, shell body only plays fixed body and the effect that is connected with excavator, when quartering hammer in the long course of work, because the powerful of driven plunger moves up and down at a high speed, in body, produce great impact power, connect driver A, the body bolt D that passes through of accumulator B and drill steel seat assembly C causes fracture easily and causes quartering hammer to work under the impulsive force compressing; And since the single deck tape-recorder position groove 1 that plays fixed body and shell body open above the cotter pilotage position 3 of drill steel seat assembly, driven plunger is carried out in the process of work at driving drill steel 4, flat lockpin hole place is broken by drill steel 3 and flat lock pin 3 impulsive forces than being easier to again, thereby causes scrapping of whole drill steel seat.
Summary of the invention
The problem that the flat lockpin hole place of passing through easily more disconnected by the stress shake and the drill steel seat assembly of body bolt at existing quartering hammer is broken by drill steel and flat lock pin easily, the present invention proposes a kind ofly can prevent to pass through the body bolt and shaken the disconnected novel hydraulic quartering hammer assembly that the drill steel seat assembly is broken at flat lockpin hole place that can prevent again.
For reaching goal of the invention, drill steel seat assembly of the present invention adopts the two screens groove structures of spill, the screens clamping plate of shell body adopt two screens structures, simultaneously install the hold-down bolt connecting plate additional at the shell body afterbody, have screw socket everywhere at the connecting plate place, when body and shell body are installed when being connected, the two screens grooves of spill at two screens clamping plate of the convex of shell body and body drill steel seat position are harmonious, tighten hold-down bolt with the afterbody (accumulator) of hold-down bolt from the screw socket of the hold-down bolt connecting plate reserved toward body, and then tighten the shell body bolt, two screens clamping plate by hold-down bolt and shell body just can utilize shell body once more body to be continued tension like this, make body and shell body become real integral body.
The invention has the beneficial effects as follows, realization is connected shell body and the real meaning of body, reduces the risk that quartering hammer passes through the fatigue fracture of body bolt in the course of the work and breaks the drill steel seat because of the impact of drill steel and flat lock pin, improve the service life of quartering hammer, increased economic benefit.

The specific embodiment
With reference to the structural representation of Fig. 4 to hydraulic breaking hammer assembly of the present invention shown in Figure 6, hydraulic breaking hammer assembly of the present invention comprises hydraulic unit driver A, accumulator B, drill steel seat assembly C, passes through body bolt D, connecting plate (being shell body) E and shell body turnbuckle F is installed, wherein drill steel seat assembly C comprises drill steel 24 and the flat lock pin 23 of drill steel, pass through body bolt D and driver A, accumulator B are connected tension become breaking hammer main body with drill steel seat assembly C, shell body is linked by the tension of shell body turnbuckle with body; Drill steel seat assembly C is provided with the two screens grooves 21 of spill, is connected and fixed the position at shell body and body drill steel seat the two screens clamping plate 22 of convex are set, and matches with described spill pair screens grooves 21; Afterbody at shell body is provided with hold-down bolt connecting plate 15, is provided with hold-down bolt 16 in it.
Drill steel seat assembly of the present invention adopts the two screens groove structures of spill, the screens clamping plate of shell body adopt two screens structures, simultaneously install the hold-down bolt connecting plate additional at the shell body afterbody, have screw socket everywhere at the connecting plate place, when body and shell body are installed when being connected, the two screens grooves of spill at two screens clamping plate of the convex of shell body and body drill steel seat position are harmonious, tighten hold-down bolt with the afterbody (accumulator) of hold-down bolt from the screw socket of the hold-down bolt connecting plate reserved toward body, and then tighten the shell body bolt, two screens clamping plate by hold-down bolt and shell body just can utilize shell body once more body to be continued tension like this, make body and shell body become real integral body.
Adopt the drill steel seat assembly and fixing its shell body of hydraulic breaking hammer assembly of two screens clamping plate of hold-down bolt and two screens groove structures can not only play fixed body and the effect that is connected excavator, can also play the function of further tension body, make quartering hammer strengthen the anti-impact force of body at work, further strengthened passing through the fatigue crack-resistant of body bolt, simultaneously because the drill steel seat assembly adopts the structure Design of two draw-in grooves also to reduce the anti-impact force at place, drill steel seat cotter pilotage position widely, the risk that reduction is broken by drill steel and cotter pilotage impulsive force has strengthened the service life of quartering hammer and has increased economic efficiency.
The present invention is not limited to described embodiment, and those skilled in the art still can do some corrections or change, so the scope of the present invention is as the criterion with claims restricted portion not breaking away from spirit of the present invention promptly openly in the scope.
