Description

Technical Field

[0001] This utility model relates to the field of hydraulic cylinder technology, and more specifically, to an integrated drilling rig hydraulic cylinder. Background Technology

[0002] A drilling rig is a mechanical device used in the exploration or development of mineral resources (including solid, liquid, and gaseous minerals) to drive drilling tools into the ground and obtain physical geological data. Its main function is to drive the drilling tools to break the rock at the bottom of the hole and to lower or lower the drilling tools into the hole.

[0003] Hydraulic cylinders are the core actuators in hydraulic systems, converting hydraulic energy into mechanical energy. They are widely used in engineering machinery, industrial equipment, and other fields, and play an important role in the feeding devices of drilling rigs.

[0004] The existing drilling rig feed device only fixes the cylinder body and does not limit or buffer the rotation of the piston rod. This can easily lead to severe vibration of the wire rope during operation, which in turn affects the drilling rig's working performance and the service life of the cylinder. Utility Model Content

[0005] In view of the problems existing in the prior art, the purpose of this utility model is to provide an integrated drilling rig hydraulic cylinder, which aims to solve the problems mentioned in the background art.

[0006] To solve the above problems, the present invention adopts the following technical solution:

[0007] Integrated drilling rig hydraulic cylinder, including:

[0008] A cylinder body, on which a piston rod is mounted, and a plurality of positioning plates are fixedly fitted onto the outer surface of the cylinder body; and

[0009] A buffer mechanism, located on the piston rod, is used to buffer the vibrations generated by the rotation of the piston rod.

[0010] As a preferred embodiment of this utility model, the buffer mechanism includes two arc-shaped fixing plates, each arc-shaped fixing plate being sleeved on the outer surface of the piston rod, each arc-shaped fixing plate having a U-shaped track fixedly connected to its outer wall, each U-shaped track having a support sleeve movably sleeved on its outer surface, each support sleeve having a buffer cavity on both sides of its outer wall, each arc-shaped fixing plate having two arc-shaped buffer rods fixedly connected to its outer wall, and each arc-shaped buffer rod having a buffer block fixedly connected to one end, and each buffer block being movably embedded in the corresponding buffer cavity.

[0011] As a preferred embodiment of this utility model, each of the arc-shaped buffer rods is fitted with an arc-shaped spring on its outer surface.

[0012] As a preferred embodiment of this utility model, each of the support sleeves has a limit strip fixedly connected to the inner walls on both sides, and the U-shaped track has a corresponding limit groove on the outer walls on both sides.

[0013] As a preferred embodiment of this utility model, each of the arc-shaped fixing plates has two connecting plates fixedly connected to its outer wall, and each pair of connecting plates is fixedly connected by bolts and nuts.

[0014] As a preferred embodiment of this utility model, a support positioning frame is fixedly installed between the outer walls of the two support sleeves.

[0015] Beneficial effects

[0016] Compared with the prior art, this utility model provides an integrated drilling rig hydraulic cylinder, which has the following advantages:

[0017] 1. In this solution, the cylinder body and piston rod constitute the complete hydraulic cylinder of the drilling rig. The piston rod moves back and forth inside the cylinder body to realize the feeding operation of the drilling rig. The positioning plate can easily fix the cylinder body to the drilling frame of the drilling rig. The buffer mechanism can easily limit and buffer the piston rod, which reduces the vibration generated by the rotation of the piston rod to a certain extent and improves the service life of the drilling rig hydraulic cylinder.

[0018] 2. In this design, two arc-shaped fixing plates are fixed to one end of the outer wall of the piston rod. The support sleeve is fitted onto the U-shaped track. The support sleeve facilitates the support of the arc-shaped fixing plates. One end of the arc-shaped buffer rod on the arc-shaped fixing plate is located inside the buffer cavity on the support sleeve. The arc-shaped buffer rod connects the support sleeve and the arc-shaped fixing plate, which can suppress the rotation of the piston rod to a certain extent. The buffer cavity is filled with damping fluid. Through the cooperation of the buffer block and the damping fluid, it is convenient to provide buffering when the piston rod rotates.

The buffer cavity 404 is filled with damping fluid. The buffer block 406 and the damping fluid cooperate to provide buffering when the piston rod 2 rotates.

[0032] Please refer to the specific details. Figure 2-3 As shown, each arc-shaped buffer rod 405 has an arc-shaped spring 5 fitted on its outer surface.

[0033] In this embodiment, the arc spring 5 increases the strength of the buffer rod 405 against the support sleeve 403, thereby improving the performance of the buffer mechanism 5. At the same time, the arc spring 5 facilitates the reset of the two support sleeves 403.

The cylinder 1 is fixed to the drill frame by positioning plate 3. The piston rod 2 between the support sleeve 403 and the arc-shaped fixing plates 401 is installed and positioned by support positioning frame 8. The two arc-shaped fixing plates 401 are fixed to one end of the outer wall of the piston rod 2. The support sleeve 403 is sleeved on the U-shaped track 402. One end of the arc-shaped buffer rod 405 on the arc-shaped fixing plate 401 is located inside the buffer cavity 404 on the support sleeve 403. The support sleeve 403 and the arc-shaped fixing plate 401 are connected by the arc-shaped buffer rod 405 and the arc-shaped spring 5, which can suppress the rotation of the piston rod 2 to a certain extent. The buffer cavity 404 is filled with damping fluid. The buffer block 406 and the damping fluid work together to provide buffering when the piston rod 2 rotates.
