[0002] During the installation of the hydraulic cylinder, the installation position accuracy and whether the cylinder axis is parallel to the guide rail surface are key indicators for its smooth use. In conventional lifting device products, the guide rails are often assembly structures, and the verticality differences between each guide rail surface and the installation surface are different. Considering the fluctuations in the spacing size between the guide rails, what actually needs to be ensured is that the cylinder axis is parallel to the center plane of the fitting of each parallel guide rail surface.

[0003] The hydraulic oil cylinder installation accuracy detection device in the lifting device with patent announcement number CN220380484U includes a mounting plate, a suspended fitting panel is provided on the mounting plate, mounting seats are provided on both sides of the end of the fitting panel, a plurality of sliding measuring cylinders are provided in the mounting seat, one end of the measuring cylinder slides against the guide rail, and the other end against the fitting panel, causing the fitting panel to deviate, and a displacement sensor is provided on one side of the fitting panel for detecting the deflection of the fitting panel; a connecting seat is fixed at the bottom of the mounting plate, and the piston rod end of the hydraulic oil cylinder is fixed in the connecting seat. By materializing the fitting center plane, the spacing dimension fluctuation of the hydraulic oil cylinder relative to the materialized fitting center plane is measured, so as to judge the position accuracy and axis deviation of the hydraulic oil cylinder, and then guide the installer to adjust the oil cylinder according to the specific data, but in the process of adjusting the spacing between different guide rails, the installer needs to tighten the multiple rear cylinders and cover cylinders one by one, which makes the adjustment operation more cumbersome, so a hydraulic oil cylinder installation accuracy detection device is needed to improve the above problem. Utility Model Content

[0004] In order to overcome the above-mentioned defects, the utility model provides a hydraulic cylinder installation accuracy detection device, which solves the problem that in the process of adjusting to adapt to the spacing between different guide rails, the installer needs to tighten multiple rear cylinders and cover cylinders one by one, which makes the adjustment operation more cumbersome.

DETAILED DESCRIPTION

[0019] The technical solution of this patent is further described in detail below in conjunction with specific implementation methods.

[0020] like Figure 1-3 As shown, the utility model provides a technical solution: a hydraulic cylinder installation accuracy detection device, including a mounting plate 1, four mounting seats 7 are arranged on the mounting plate 1, two rear cylinders 13 are arranged in the mounting seats 7, a rear pressure shaft rod 8 is slidably connected in the rear cylinder 13, a suspended fitting panel 10 is arranged on the mounting plate 1, the rear pressure shaft rod 8 overlaps the fitting panel 10, a cover cylinder 12 is slidably connected to the side of the rear cylinder 13, a front pressure shaft rod 11 is slidably connected in the cover cylinder 12, a spring 20 is arranged on the side of the rear pressure shaft rod 8, and the spring 20 is arranged to prevent the rear pressure shaft rod 8 from being damaged. The forces at both ends of the spring 20 are equal, and the force of the spring 20 is proportional to the compression amount. When the parallelism between the central axis of the hydraulic cylinder and the guide surface changes, the central fitting plane plate is immediately offset under the action of the spring 20 force. The other end of the spring 20 is connected to the front pressure shaft rod 11, and the other end of the front pressure shaft rod 11 is provided with an axle wheel 3. The front and back sides of the mounting plate 1 are both rotatably provided with movable rods 17, and one end of the movable rod 17 is provided with a turntable 9. By setting the turntable 9, the turntable 9 makes it more convenient for the staff to rotate the movable rod 17.

[0021] The other end of the movable rod 17 is provided with a first bevel gear 15, and the first bevel gear 15 is meshed with a second bevel gear 16. By setting the first bevel gear 15 and the second bevel gear 16, under the mutual cooperation of the first bevel gear 15 and the second bevel gear 16, the force of the movable rod 17 rotating in the vertical direction can be converted into the force of the screw rod 14 rotating in the vertical direction. A positioning bearing 18 is provided in the mounting plate 1, and a screw rod 14 is provided in the positioning bearing 18. By setting the positioning bearing 18 and the screw rod 14, the positioning bearing 18 supports and limits the screw rod 14, so that the screw rod 14 can rotate smoothly in the positioning bearing 18, and the screw rod 14 and the second bevel gear 16 can rotate smoothly. The bevel gear 16 is connected, and the side of the screw rod 14 is threadedly connected to two connecting nuts 19. A moving rod 6 is provided on the connecting nut 19. A through hole 5 is overlapped on the side of the moving rod 6. By setting the through hole 5 and the moving rod 6, the through hole 5 supports and limits the moving rod 6, so that the moving rod 6 can slide smoothly in the through hole 5. The through hole 5 is opened on the mounting plate 1, and two connecting blocks 4 are provided on the back of the moving rod 6. The connecting block 4 is connected to the cover tube 12. A displacement sensor 2 is provided on the mounting plate 1. By setting the displacement sensor 2, the displacement sensor 2 is used to detect the offset value of the fitting panel 10, so as to facilitate the adjustment of the position of the hydraulic cylinder.

[0022] The working principle of the utility model is:

[0023] When the spacing between the adaptable guide rails needs to be adjusted, the turntable 9 is first controlled to rotate, so that the turntable 9 drives the movable rod 17 to rotate, and the movable rod 17 drives the first bevel gear 15 to rotate. Since the first bevel gear 15 and the second bevel gear 16 are meshed and rotated, the second bevel gear 16 drives the screw rod 14 to rotate, and the screw rod 14 drives the two connecting nuts 19 to move away from each other during the rotation process;

[0024] The two connecting nuts 19 drive the two moving rods 6 to move away from each other, and the two moving rods 6 drive the two connecting blocks 4 and the cover tube 12 to move away from each other, until the two cover tubes 12 drive the two front pressure shaft rods 11 and the two shaft wheels 3 to roll against the guide rails, thereby successfully completing the adjustment to adapt to the spacing between different guide rails.

[0025] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installation", "connection" and "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be an indirect connection through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood by specific circumstances.

[0026] The above describes in detail the preferred implementation of this patent, but this patent is not limited to the above implementation. Various changes can be made within the knowledge scope of ordinary technicians in this field without departing from the purpose of this patent.
