Technical Field

The utility model relates to the technical field of parking of stereo garages, in particular to a rear upright post structure for preventing chain jump.

Background

The three-dimensional parking equipment is generally divided into: mechanical, self-propelled and semi-mechanical three types; according to the three-dimensional parking equipment, the three-dimensional parking equipment can be roughly divided into: lifting and traversing type, vertical circulating type, tunnel stacking type, vertical lifting type, simple lifting type and the like. The three-dimensional parking equipment can be divided into self-propelled three-dimensional parking equipment, semi-automatic three-dimensional parking equipment and full-automatic three-dimensional parking equipment, and household mini three-dimensional parking equipment, and the full-automatic three-dimensional parking equipment can be further divided into two-layer or multi-layer planar full-automatic three-dimensional parking equipment, vertical intensive full-automatic three-dimensional parking equipment and full-automatic three-dimensional parking equipment with special modeling structures.

The three-dimensional parking equipment has the following advantages:

1. The high-magnification technical and economic index three-dimensional parking equipment has large parking capacity. The floor area is small, and various types of vehicles, in particular, cars can be parked. The investment is less than that of the underground garage with the same capacity, the construction period is short, the power consumption is saved, and the occupied area is far less than that of the underground garage.

2. The appearance is coordinated with the building, and the stereoscopic parking equipment convenient to manage is most suitable for being used in malls, hotels, front of office buildings and tourist areas. Many devices do not require specialized operators and can be implemented by a single driver.

3. Complete supporting facilities and the environment-friendly automatic stereo garage are provided with complete safety systems, such as obstacle confirmation devices, emergency braking devices, sudden drop prevention devices, overload protection devices, electric leakage protection devices, vehicle overlength and superelevation detection devices and the like. The access process can be completed manually or fully automatically by being equipped with computer equipment, which also leaves a large space for future development and design.

For example, a liftable parking space with a patent number of CN 116927561A discloses a lifting parking space which comprises a bottom plate, wherein upright posts are arranged on the periphery of the bottom plate, a support frame is arranged on the upright posts, a controller is arranged on the upright posts, a vehicle carrying plate capable of moving up and down is arranged on the support frame, a rotating rod is rotatably arranged on the upright posts on the rear side of the support frame, a motor drives the rotating rod to rotate, double-row gears are symmetrically arranged at two ends of the rotating rod respectively, a first chain and a second chain are arranged on the double-row gears, and driven gears are rotatably arranged in frames on two sides of the support frame respectively; the front end of the second chain is fixedly connected with the rear end of the vehicle carrying plate; the invention can realize double-layer placement of the vehicle, namely, after the vehicle is parked on the vehicle carrying plate, the vehicle carrying plate is moved upwards to continuously park the vehicle on the bottom plate below the vehicle carrying plate; the space is saved, and the drag chain piece and the jump preventing piece are arranged to prevent the chain from being separated from the gear, so that safety accidents are caused; the anti-falling mechanism is arranged, so that the anti-falling mechanism can gradually control and protect the vehicle carrying plate from falling accidents step by step, and can conveniently check faults. The structure can realize lifting of a vehicle, has the function of placing a jump chain by the chain, but can shake when the chain drives the drag chain piece to move up and down, frequently collides with the upright post structure, causes chain winding and generates larger noise, and the phenomenon that the drag chain piece jumps up and down still exists when the movement speed of the chain is too fast.

In order to solve the above problems, we provide a rear pillar structure for preventing chain jump, which can place a chain disengaging gear and simultaneously prevent the drag chain member from jumping up and down and prevent the drag chain member from shaking.
