The invention provides a hydraulic control device for a derrick transferring base. The hydraulic control device solves the problem about hydraulic control over the derrick transferring base, can achieve the functions of synchronous ascending and descending actions of all supporting leg oil cylinders, the fine adjustment action of single ascending and descending of each supporting leg oil cylinder and the steering function of a set of front steering oil cylinders and a set of rear steering oil cylinders and can also achieve the interlocking function and the misoperation alarming function. According to the technical scheme, the hydraulic control device comprises a multifunctional movable hydraulic station, the set of front steering oil cylinders, the set of rear steering oil cylinders and the multiple supporting leg oil cylinders, wherein the set of front steering oil cylinders and the set of rear steering oil cylinders are connected with the multifunctional movable hydraulic station. The multifunctional movable hydraulic station is internally provided with multiple branch switches and a main switch. The front steering oil cylinders are jointly connected with one branch switch. The rear steering oil cylinders are jointly connected with one branch switch. Each supporting leg oil cylinder is connected with one branch switch, and meanwhile all the supporting leg oil cylinders are jointly connected with the main switch.
Description
Technical field [0001] The invention relates to a hydraulic control device, in particular to a hydraulic control device used for a derrick to move a base. Background technique [0002] The hydraulic control device is one of the important systems of the derrick transportation device, and an important guarantee for the normal lifting of various equipment in the derrick. For the derrick transport base, the hydraulic control device must not only realize the synchronous lifting of all outrigger cylinders, and the outrigger cylinders individually lift, but also realize the steering function of the front and rear steering cylinders. The hydraulic control device currently used for the lifting and lowering of the outrigger cylinders can only realize the lifting and lowering functions of the outrigger cylinders, and cannot realize the front and rear steering functions. Summary of the invention [0003] The invention provides a hydraulic control device for the derrick moving base, which sol...
