Description
Technical Field
The utility model relates to a pile equipment field, in particular to hydraulic pressure pipeline connection structure for hydraulic pressure vibration pile hammer.
Background
With the vigorous development of the foundation construction in China, the use amount of foundation pile construction equipment is increased, and the hydraulic vibration pile driving hammer is used as one of the foundation pile construction equipment and is applied more and more widely. The hydraulic motor is used as an important driving part of the vibratory pile driving hammer, and whether the arrangement and the connection of the oil inlet pipeline and the oil return pipeline are reasonable or not is a key problem.
The problems exist at present: the hydraulic motor is an important driving component of the hydraulic vibration hammer, and a hydraulic pipe and a hydraulic joint are usually connected to a pipeline connection. However, the hydraulic pipe pressure head needs to have a certain length and is too short to be connected; the hydraulic vibration pile driving hammer has a compact overall structure and is also subjected to the influences of vibration, pressure, temperature and environment. Conventional joint has fixed length, and hydraulic motor locating position needs adjust according to the length and the angle of pipeline and joint, in order to reach fixed position size sometimes, just needs the holistic arrangement of adjustment vibration pile hammer, causes the size to be on the large side, influences complete machine weight and performance.
Disclosure of Invention
The utility model aims to solve the technical problem that a hydraulic pressure pipeline connection structure for hydraulic pressure vibration pile hammer is provided.
In order to achieve the above object, the utility model adopts the following technical scheme:
the utility model provides a hydraulic pressure pipeline connection structure for hydraulic pressure vibration pile hammer, includes valve block, hydraulic motor's oil inlet and oil-out are connected with the valve block through the coupling respectively, and the coupling includes seal receptacle one, seal receptacle two, leads to oil pipe, and seal receptacle one is established to the outside cover of the one end that leads to oil pipe, seal receptacle one and hydraulic motor bolted connection, lead to the inner chamber that oil pipe's the other end stretched into seal receptacle two to with the inner chamber sliding seal of seal receptacle two, seal receptacle two and valve block bolted connection.
An end face sealing ring is arranged between the end face of the oil through pipe and the hydraulic motor.
And a first joint sealing ring and a second joint sealing ring are arranged between the periphery of the oil pipe and the inner cavity of the second sealing seat.
Compared with the prior art, the beneficial effects of the utility model are that:
the utility model provides a problem that hydraulic motor and valve block rigidity can not be adjusted. The distance and angle fine adjustment from the hydraulic motor to the valve block can be realized, and the deviation of the distance and angle of the equipment under the influence of vibration, pressure and temperature can be compensated. Avoiding oil leakage.
