Technical field
The utility model designs a kind of breaking hammer change-over valve mounting structure technical field, concretely relates to a kind of novel
Hydraulic breaking hammer change-over valve cover attaching construction.
Background technique
Referred to as " quartering hammer " or " destroyer ", the power resources of hydraulic breaking hammer are excavator, loading machine to hydraulic breaking hammer
Or the pressure that pumping plant provides, it can in engineering construction can more effectively broken stone and rock, improve working efficiency.
The stability of reversal valve is most important for quartering hammer working performance, how to guarantee that its is reliable and stable, is used for a long time
Will not leak is a problem to be solved.
Summary of the invention
The purpose of the utility model is to provide a kind of novel hydraulic crushing hammer reversal valve cover attaching construction, it is intended to solve back
The problems in scape technology.
In order to solve the above technical problems, purpose of the utility model is realized as follows:
A kind of novel hydraulic crushing hammer reversal valve cover attaching construction, including middle cylinder body, rear-bank rotor housing, be mounted on middle cylinder body and
Its floating end is exposed to the reversal valve of middle cylinder body and rear-bank rotor housing joint face, one end is against on the joint face of rear-bank rotor housing and middle cylinder body and
The other end is pressed against the valve deck of reversal valve floating end, built in reversal valve, can will reduce exposed part letter using this structure
Change external structure and reduce the use of connector, while its is relatively reliable.
Preferred embodiment on the basis of above scheme and as above scheme: the middle cylinder body is installed with reversal valve
Hole, reversal valve are mounted in the mounting hole, and valve deck is mounted in the opening of the reversal valve mounting hole and holds out against reversal valve one end, valve
The opened gap of lid and reversal valve mounting hole cooperates and sealing element is provided therebetween.
Preferred embodiment on the basis of above scheme and as above scheme: the reversal valve mounting hole offers
Internal diameter is greater than the valve deck mounting hole of interior reversal valve mounting hole internal diameter, and valve deck is installed in the valve deck mounting hole.
Preferred embodiment on the basis of above scheme and as above scheme: the hole depth of the valve deck mounting hole be equal to or
The thickness of the slightly smaller than described valve deck guarantees that valve deck can be installed reliably and is limited in valve deck mounting hole, prevents its play.
Preferred embodiment on the basis of above scheme and as above scheme: the valve deck circumferential surface offers sealing ring peace
Tankage is equipped with sealing element in the sealing ring mounting groove, and sealing element prevents the medium of reversal valve side from revealing.
Preferred embodiment on the basis of above scheme and as above scheme: the valve deck its middle part and be located at rear-bank rotor housing
Side offers location hole, and rear-bank rotor housing has a positioning column that can enter the location hole accordingly, and positioning column enters positioning hole will
Valve deck is positioned.
Preferred embodiment on the basis of above scheme and as above scheme: the positioning column and location hole screw thread connect
It connects, so valve deck is fixed on rear-bank rotor housing and is positioned, convenient for the assembling of middle cylinder body and rear-bank rotor housing.
Compared with the prior art, the utility model has prominent and beneficial technical effects that: can be by reversal valve using this structure
It is built-in, it reduces exposed part and simplifies external structure and reduce the use of connector, and reversal valve and valve deck cooperation are more smart
Really, stabilization reliable for operation, be used for a long time will not leak, failure rate it is low.
Detailed description of the invention
Fig. 1 is the overall structure diagram of the utility model；
Fig. 2 is the partial enlarged view in Fig. 1；
Fig. 3 is valve cover structure schematic diagram.
Specific embodiment
To keep the purposes, technical schemes and advantages of the application clearer, below in conjunction with the attached drawing in embodiment, to reality
The technical solution applied in example is clearly and completely described,
A kind of novel hydraulic crushing hammer reversal valve cover attaching construction, including middle cylinder body 30, rear-bank rotor housing 10, it is mounted on middle cylinder body
On 30 and its floating end is exposed to middle cylinder body 30 and is against rear-bank rotor housing 10 and middle cylinder with the reversal valve 40 of 10 joint face of rear-bank rotor housing, one end
On the joint face of body 30 and the other end is pressed against the valve deck 20 of 40 floating end of reversal valve.
Specifically, middle cylinder body 30 has reversal valve mounting hole 32, reversal valve 40 is mounted in the reversal valve mounting hole 32, changes
The valve deck mounting hole 31 that internal diameter is greater than interior 32 internal diameter of reversal valve mounting hole is offered to valve mounting hole 32, valve deck 20 is installed on
In the valve deck mounting hole 31, (valve deck 20 is mounted in the opening of the reversal valve mounting hole 32 and holds out against 40 one end of reversal valve, i.e., floating
Moved end), valve deck 20 and 31 clearance fit of valve deck mounting hole, 20 circumferential surface of valve deck offer sealing ring mounting groove 21, sealing ring peace
Sealing element 50 is installed in tankage 21.
Preferably, the hole depth of valve deck mounting hole 31 is slightly smaller than the thickness of valve deck 20.
Further, its middle part of valve deck 20 and it is located at 10 side of rear-bank rotor housing and offers location hole 22, rear-bank rotor housing 10 has accordingly
There is a positioning column 11 that can enter the location hole 22.
