Underground bicycle garage with laser spacing function

Abstract

The invention relates to an underground bicycle garage with a laser spacing function. The underground bicycle garage is composed of a spliced support unit and a central conveying unit. The spliced support unit consists of a cage type cylinder and multi-layer bicycle storage frames arranged at the positions, facing the axis, on the inner wall of the cage type cylinder circumferentially. The central conveying unit is arranged at the axis of the spliced support unit and consists of parallel rotation guide rails, a synchronous belt type lifting mechanism, a shaft supporting type rotation mechanism and a conveying platform. A laser distance measuring sensor is arranged on the lower surfaces of the tops of the rotation guide rails. A reflection plate is arranged at the position, corresponding to the laser distance measuring sensor, of the upper surface of the conveying platform, and the signal output end of the laser distance measuring sensor is connected to a control system. According to the underground bicycle garage, grabbing and precise lifting, rotation and pushing of bicycles can be completed, and the bicycles can be aligned and put in the bicycle storage frames, so that the number of the bicycles stored is large, ground space is saved, the structure is reasonable, safety is good, and operation is stable and efficient.

Description

technical field [0001] The invention belongs to a bicycle storage garage, in particular to an underground bicycle garage with a laser distance-fixing function. Background technique [0002] China is a big country of bicycles, and the popularity and usage rate of bicycles in China are very high. For the storage and parking of bicycles, most of them are in the form of above-ground bicycle garages. The relatively simple above-ground bicycle parking garages are mostly carports, which have a small number of bicycles, and a single bicycle occupies a large area, which is disorderly and easily lost. There are also some three-dimensional bicycle storage devices, which can realize multi-layer parking of bicycles, but they still need to occupy a lot of ground space, which affects the appearance of the city. [0003] Chinese Patent No. 201210171767.1 discloses an underground bicycle garage, which includes a cylindrical side wall, a mechanical turntable located in the sidewall, and a b...

AI Technical Summary

Problems solved by technology

1. The structure of the side wall is unreasonable: the side wall of the cylinder used in the underground bicycle storage is a continuous solid wall surface, which is not only difficult to construct, high in cost, and difficult to transport; There are problems such as difficult positioning, poor position accuracy, and difficult installation

2. The safety of the lifting device is not good: the lifting device is installed on both sides of the lifting platform with gears that mesh with the rack on the inner wall of the column, and the gear is driven by a motor to make the lifting platform go up and down along the column

The design of this kind of lifting device is not reasonable and scientific. The lifting platform is in a suspended state. The overall support of the lifting platform is completely attached to the bite force between the gear and the rack. It is easy to cause deflection during operation and affect the normal operation of the equipment. There are even safety hazards

3. The rotating device is unreasonable: the structural design of the rotating device is unreasonable, and the rotating bearing is subjected to a large radial force, which is easy to cause damage and affects the safe operation and service life of the equipment

The screw drive method used in it leads to a very low horizontal movement speed of the mechanical arm, and it takes a lot of time to pick and place each bicycle, and the user has to wait for a long time to pick up the bike.

Moreover, the structure of the mechanical arm is simple, and the bicycle wheel is directly clamped. There is sliding friction between the clamped bicycle wheel and the wheel guide groove on the mechanical turntable, which not only needs to increase the power of the drive motor, but also easily produces slippage, resulting in the failure of the gripping of the robotic arm and affecting the normal operation of the equipment

[0005] Moreover, in the existing underground bicycle storage, the lifting height control method of the lifting platform is not good
