Description

Technical Field

[0001] This utility model relates to the field of hydraulic cylinder processing equipment, and specifically to a clamping device for testing lifting cylinders. Background Technology

[0002] A trailer lifting cylinder is a hydraulic device used to raise or lower the trailer bed. After assembly, the lifting cylinder needs to undergo pressure testing.

[0003] Chinese utility model patent CN219827348U discloses a pressure testing device for hydraulic cylinders. This device includes a worktable, a cylinder fixedly connected to the top of a top plate, a lifting plate fixedly connected to the piston end of the cylinder, a fixed frame fixedly connected to the bottom of the lifting plate, a fixed block fixedly connected to the middle of the top of the worktable, and a placement frame fixedly connected to the inner side of the fixed block. While this pressure testing device can perform clamping tests on ordinary hydraulic cylinders, it is difficult to adapt to lifting cylinders with a telescopic length of six to seven meters.

[0004] Therefore, a new technical solution is needed in this field to solve the above problems. Summary of the Invention

[0005] To improve or solve the technical problem that existing pressure testing devices are difficult to adapt to lifting cylinders with long telescopic lengths, this utility model provides a clamping device for testing lifting cylinders.

[0006] This utility model discloses a clamping device for testing a lifting cylinder, comprising a guide rail and a clamping structure. The clamping structure includes a fixed base, a movable base, and a support base. The fixed base is fixed to one end of the guide rail and has a first clamping member on it, supporting one end of the cylinder. The movable base is movably mounted on the guide rail and has a second clamping member on it, supporting the other end of the cylinder, thus fixing the cylinder. Simultaneously, the movable base can move on the guide rail, adapting to cylinders of different lengths and improving the applicability of the clamping device. The support base is movably mounted on the guide rail and has a support platform on it, supporting the end of the piston rod. The support base moves with the extension and retraction of the piston rod, always remaining below the end of the piston rod. Rubber pads are arranged on the first clamping member, the second clamping member, and the support platform to prevent the clamping members and the support platform from scratching or abrading the lifting cylinder. With the above-described configuration, the clamping device for testing lifting cylinders of this utility model includes a guide rail, a fixed seat, a support seat, and a support platform, which can conveniently test lifting cylinders with long telescopic lengths and large sizes. The structure is simple and easy to use.

[0007] Furthermore, the first clamping member includes a base plate connected to the fixed seat, a vertical plate mounted on the base plate, a first abutting plate mounted on the vertical plate, and a second abutting plate arranged opposite to the first abutting plate; the first abutting plate and the second abutting plate are arranged at an angle.

[0008] Furthermore, a hinge structure and a limiting structure are provided between the upright plate and the first abutment plate; the hinge structure includes a hinge shaft mounted on the upright plate and a hinge seat mounted on the first abutment plate.

[0009] Furthermore, the limiting structure includes a limiting block installed on the first abutment plate, a limiting bolt disposed on the limiting block, and a limiting groove formed on the upright plate, wherein the limiting bolt is arranged in the limiting groove.

[0010] Furthermore, a reinforcing plate is provided between the base plate and the upright plate.

[0011] Furthermore, the movable seat includes a wheel that matches the guide rail, a rotating shaft connected to the wheel, a sleeve sleeved on the outer side of the rotating shaft, and a mounting platform connected to the sleeve; the second clamping member is mounted on the mounting platform.

[0012] In summary, compared with the prior art, this utility model has the following beneficial effects:

[0013] With guide rails, fixed seats, support seats, and support platforms, it is relatively easy to inspect lifting cylinders with long telescopic lengths and large sizes. The structure is simple and easy to use. Attached Figure Description

The clamping structure includes a fixed base 2, a movable base 3, and a support base 4.

[0023] Figure 2 This is a schematic diagram of the first clamping member 5 in a clamping device for testing a lifting cylinder according to this utility model. Figure 1 and Figure 2 As shown, the fixing seat 2 is arranged at one end of the guide rail 1. Based on Figure 1 As shown, the fixing seat 2 is located at the left end of the guide rail 1. In one or more embodiments, the fixing seat 2 is generally rectangular box-shaped. Alternatively, the fixing seat 2 includes two opposing vertical plates 52 and a horizontal plate arranged above the two vertical plates 52. A supporting inclined beam is provided between the two vertical plates 52. Further, a first clamping member 5 is provided above the fixing seat 2, located at the top center of the fixing seat 2, for supporting the cylinder. The first clamping member 5 includes a base plate 51 connected to the fixing seat 2, a vertical plate 52 mounted on the base plate 51, a first abutment plate 53 mounted on the vertical plate 52, and a second abutment plate 54 arranged opposite to the first abutment plate 53. Specifically, the base plate 51 is generally rectangular plate-shaped, and the vertical plate 52 extends vertically upward from the base plate 51. A reinforcing plate 55 is provided between the vertical plate 52 and the base plate 51, increasing the connection stability between the vertical plate 52 and the base plate 51. Furthermore, the upright plate 52 includes a first half 521 and a second half 522 arranged in a mirror image, both of which are roughly in the shape of a right trapezoid.

[0024] See also Figure 1 and Figure 2The first abutment plate 53 is inclined and adjustablely mounted on the first half 521. In one or more embodiments, a hinge structure 6 and a limiting structure 7 are provided between the first half 521 and the first abutment plate 53. The hinge structure 6 allows the first abutment plate 53 to be rotatably mounted on the first half 521, and the limiting structure 7 can fix the first abutment plate 53 on the first half 521. Specifically, the hinge structure 6 includes a hinge shaft 61 mounted on the top of the first half 521 and a hinge seat 62 mounted on the first abutment plate 53. A fixing cylinder 63 that mates with the hinge shaft 61 is provided on the top of the first half 521, and the hinge seat 62 includes two hinge cylinders arranged on both sides of the fixing cylinder 63. The hinge shaft 61 passes through the hinge cylinders and the fixing cylinder 63, so that the first half 521 and the first abutment plate 53 form a hinged connection. Furthermore, the limiting structure 7 includes a limiting block 71 fixed to the first abutment plate 53, a limiting bolt 72 disposed on the limiting block 71, and a limiting groove 73 formed on the first half 521.

The limiting groove 73 is generally arc-shaped, and the limiting bolt 72 is slidably disposed within the limiting groove 73. When the first abutment plate 53 is adjusted to a suitable angle, the nut of the limiting bolt 72 is tightened, fixing the limiting block 71 to the first half 521, thereby fixing the tilt angle of the first abutment plate 53. Furthermore, a shim can be placed between the first abutment plate 53 and the first half 521 to prevent the limiting nut from failing to limit the position. Furthermore, a rubber pad is provided on the side of the first abutment plate 53 opposite to the first half 521. The connection structure between the first half 521 and the first abutment plate 53, and the connection structure between the second half 522 and the second abutment plate 54 are the same, and will not be described again here.
