Description

Technical Field

[0001] This utility model relates to the field of hydraulic cylinder technology, specifically to a hydraulic cylinder fixing device. Background Technology

[0002] A hydraulic cylinder, commonly known as an oil cylinder, is a linear actuator that converts hydraulic energy into mechanical energy. It produces linear reciprocating motion or oscillation. Simply put, it is a device that uses high-pressure oil to push and pull a rod. This force can be very large, ranging from several tons to tens of thousands of tons.

[0003] Existing hydraulic cylinder installation primarily relies on bolts and other connecting components passing through holes in the bottom flange mechanism to connect and fix the hydraulic cylinder to the mounting surface. However, the larger the hydraulic cylinder, the greater the output linear force and the greater the reaction force. Relying solely on bottom bolts for fixation cannot provide stable vertical positioning of the hydraulic cylinder; even slight misalignment can lead to structural damage. Therefore, an innovative design based on the existing hydraulic cylinder fixing device is urgently needed to address these issues. Utility Model Content

[0020] Example 1: Reference Figure 1 , Figure 2 , Figure 3 and Figure 4 This is the first embodiment of the present invention, which provides a hydraulic cylinder fixing device, including a hydraulic cylinder body 1, a bottom mounting plate 2 at the bottom end of the hydraulic cylinder body 1, a vertical adjustment mechanism 3 installed in the middle of the outer wall of the hydraulic cylinder body 1, a support rod 4 rotatably mounted on the vertical adjustment mechanism 3, and a bottom positioning mechanism 5 at the bottom end of the support rod 4. The vertical adjustment mechanism 3 includes a base plate 301 vertically fixed to the outer wall of the hydraulic cylinder body 1, the top end of the base plate 301 being in contact with the inner wall of the stabilizing groove 302, the stabilizing groove 302 being formed on one side of the movable plate 303, a locking bolt 304 being installed in a hole formed in the top of the other side of the movable plate 303, and the bottom of the other side of the movable plate 303 being rotatably connected to the top end of the support rod 4.

[0021] Specifically, the top view cross-sectional shape of the substrate 301 and the stabilizing groove 302 is "T" shaped. The substrate 301 is distributed at equal angles with respect to the center of the hydraulic cylinder body 1. The end of the locking bolt 304 is threaded to the locking hole 305. The locking hole 305 is opened on the substrate 301. The locking holes 305 are distributed longitudinally at equal intervals in the middle of the substrate 301. The support rod 4 is inclined. The center of the support rod 4 is on the same vertical plane as the center of the substrate 301 and the movable plate 303. The movable plate 303 slides vertically along the base plate 301 to change the position of the top of the support rod 4, and rotates the support rod 4 simultaneously to change the working posture of the support rod 4. The locking bolt 304 is connected to the locking hole 305 to fix the position of the movable plate 303 and the top of the support rod 4.

[0022] Example 2: Reference Figure 1 , Figure 2 , Figure 3 and Figure 4 This is the second embodiment of the present utility model. This embodiment is based on the previous embodiment. The bottom positioning mechanism 5 includes a bottom mounting plate 501 horizontally disposed on the outside of the bottom mounting plate 2. One end of the bottom mounting plate 501 is provided with a mounting hole 502, and the top surface of the other end of the bottom mounting plate 501 is rotatably connected to the bottom end of the support rod 4.

[0023] Specifically, a positioning groove 503 is provided on the side of the bottom mounting plate 501 near the bottom mounting disk 2.

Then, adjust the support rod 4 according to the size of the mounting surface and the installation requirements of the hydraulic cylinder body 1. Unscrew the locking bolt 304 out of the locking hole 305 and push... Figure 2The movable plate 303, with its stabilizing groove 302, slides vertically along the base plate 301, simultaneously pushing the bottom mounting plate 501, with its positioning groove 503, to slide linearly away from the bottom mounting plate 2 along the positioning plate 504. The support rod 4 also rotates adaptively until its tilt angle is appropriate and the bottom mounting plate 501 is in contact with the appropriate position of the mounting surface. The locking bolt 304 is screwed into the aligned locking hole 305 to fix the height of the movable plate 303. Bolts and other connecting tools are then used to connect and fix the movable plate 303 to the mounting surface through the mounting hole 502, thus fixing the support rod 4 and the bottom mounting plate 501. By adjusting and fixing the diagonally distributed movable plate 303, support rod 4, and bottom mounting plate 501 in sequence according to the above steps, stable support and positioning of the hydraulic cylinder body 1 can be achieved. This is the working principle of the hydraulic cylinder fixing device.
