Description

Technical Field

[0001] The utility model relates to the technical field of hydraulic devices, in particular to a hydraulic control device. Background Art

[0002] Hydraulic control refers to a method of using liquid power to change the working state of a manipulated object. During construction, it is sometimes necessary to support some building structures. Generally, the building structures are supported by the piston rod in the hydraulic cylinder. At this time, a hydraulic control device is needed.

[0003] According to the search, the Chinese patent website with patent number CN214996316U discloses "an adjustable hydraulic support device for building structure construction". By setting a chassis, a rotating seat, a hydraulic cylinder and a plug rod, the hydraulic cylinder is rotated on the rotating seat, and the rotating seat is rotated in the connecting sleeve, so as to adjust the support angle of the piston rod to the building structure, so that the whole device has the function of facilitating the adjustment of the support angle of the piston rod to the building structure. However, after the hydraulic cylinder rotates, there is no corresponding fixing mechanism, which makes it difficult for the hydraulic cylinder to maintain the adjusted angle. When supporting the building structure, the support force may be uneven due to the unstable angle, affecting the construction safety. The frequent changes in the angle also require the user to frequently repeat the adjustment process. Moreover, when the hydraulic cylinder adjusts the angle, the adjustment accuracy is not high, which may affect the construction quality in construction scenarios that require precise support angles.
