The power head device has the advantages that the power head is provided with the index plate, and the screws of the index plate are in contact with the contact points, so the direction of an oil way is changed by the travel switch controlling an electromagnetic valve, and the switching between positive rotation and reverse rotation of the power head within the angle range is conveniently realized; and the use requirements are met, the cost is low, and the operation is stable and reliable.
Description
Technical field
The utility model relates to the engineering construction rig, the power head device of especially a kind of hydraulic pressure pendulum spray.
Background technology
Churning technique is widely used in the antiseepage processing of all kinds of soft groundsill reinforcings, basement in high rise building, the regulation of great rivers dykes and dams, the reinforcing of Rail Highway bridge pier etc.The diameter of general churning pile is the cylinder of 500-1500mm, and rotary churning pile needs in a row to occur, and also interlock just can reach the effect of sealing mutually.Due to some reason in actual mechanical process; often can occur there is no interlock between stake and stake, so just not reach needed stagnant water effect, if this moment; need more material such as cement of cylinder pile meeting consumption rate of complement, also can take many underground spaces.Replenish a fan-shaped stake this moment, is best selection, so there is the pendulum pressure spray process to occur in prior art.The structure that unit head of the prior art adopts can only forward or counter-rotating, and the pendulum spray apparatus needs to carry out forward and backward in the accurate certain angular range of unit head and switches.Unit head of the prior art can't satisfy the needed movement locus of pendulum spray apparatus.
The utility model content
The applicant has only limitation with forward or counter-rotating for drilling rod unit head in above-mentioned existing production technology, can't satisfy the shortcoming of pendulum spray apparatus movement locus, the power head device of a kind of hydraulic pressure pendulum spray is provided, thereby make unit head carry out the switching of forward and reverse in selected arbitrarily angular range, satisfy instructions for use.
The technical scheme that the utility model adopts is as follows:
The power head device of a kind of hydraulic pressure pendulum spray, comprise unit head, by round nut, index dial is installed on one end face of described unit head, on described index dial outer circumference surface, the interval has a plurality of locating holes, on described locating hole, the interval is equipped with the first screw and the second screw, described the first screw and the second screw respectively by fastening nuts on the index dial outer circumference surface; Be positioned on the support of the first side of power and by securing member, installing plate be housed, by bolt, travel switch is housed on described installing plate, the described installing plate one side tactile handle that has been connected through the hinge, be extended with the first contact and the second contact on described tactile handle, described the first contact contacts with the second screw, and described the second contact contacts with the first screw.
Its further technical scheme is:
Described travel switch one side also is equipped with control system, and described control system comprises transformer, and described transformer is connected with travel switch, and an end of described transformer is connected with electromagnetic valve.
The beneficial effects of the utility model are as follows:
The utility model is rational in infrastructure, easy and simple to handle, by index dial is installed on unit head, screw on index dial contacts with the contact, change the oil circuit direction thereby make travel switch control electromagnetic valve, realized easily the switching of unit head rotating in angular range, satisfy instructions for use, cost is low, and stable operation is reliable.
