Description

Technical Field

[0001] This utility model relates to the field of rotary table technology, specifically to a car rotary table ramp structure. Background Technology

[0002] A car turntable is a piece of equipment used in photography or exhibitions. Its main function is to support and rotate vehicles to achieve the best shooting angles and exhibition effects. Car turntables have a wide range of applications and are suitable for various types of photography. When setting up a car turntable, some exhibition hall spaces lack a foundation pit, requiring the turntable to be installed on the ground, thus raising the turntable surface above the ground. For situations requiring vehicle loading and unloading, a ramp is needed. The turntable must not only meet the requirements for mobility during setup but also ensure sufficient pressure resistance and ease of maintenance. Therefore, we propose a car turntable ramp structure. Utility Model Content

[0003] The purpose of this invention is to provide a car turntable ramp structure to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a car turntable ramp structure, including a turntable body, a turntable plate installed on the upper surface of the turntable body, a ramp plate provided on the outer ring wall of the turntable body with clearance fit, and a semi-circular plate symmetrically fixedly connected to the outer side wall of the ramp plate, with circular holes symmetrically opened on the surface of the semi-circular plate.

[0005] Preferably, it also includes a support structure, which is installed on the lower surface of the ramp slab.

[0006] Preferably, the support structure includes a rotating shaft frame, with rotating shafts symmetrically rotatably connected to the side walls of the rotating shaft frame. Ten bottom wheels are installed on the outer walls of the rotating shafts, and five bottom wheels are installed on the outer walls of each rotating shaft in a sequential arrangement. Eight spring dampers are fixedly connected to the upper surface of the rotating shaft frame, arranged symmetrically side-by-side. A screw hole block is fixedly connected to the top of each spring damper. The upper surface of the screw hole block is in contact with the lower surface of the ramp plate, and a circular hole is provided at the contact point between the ramp plate and the screw hole block. The ramp plate is threadedly connected to the screw hole block via bolts.

[0007] Preferably, rubber plates are symmetrically arranged on the upper surface of the ramp slab.

[0008] Preferably, the ramp plate is inclined on the side away from the turntable body.

[0009] Compared with the prior art, the beneficial effects of this utility model are as follows: When a turntable needs to be set up, a movable ramp is set on one side of the turntable. The contact point between the ramp and the turntable is arc-shaped. No matter how the turntable rotates, the ramp can fit against the turntable while maintaining a certain distance to ensure the normal rotation of the turntable. This effectively prevents the ramp and the turntable from colliding during rotation, avoiding unnecessary damage. Moreover, multiple sets of spring dampers are set inside the ramp to increase the pressure resistance and reduce the impact force caused by inertia, thereby reducing the pressure on the ramp and further extending its service life.
