Underground bicycle garage for rotating mechanism at accurately controlled angle

Abstract

The invention relates to an underground bicycle garage for a rotating mechanism at an accurately controlled angle. The underground bicycle garage comprises an assembling type supporting unit and a central conveying unit, wherein the assembling type supporting unit is composed of a cage type barrel and a plurality of layers of bicycle storage racks peripherally arranged on the inner wall of the cage type barrel facing an axial center position; the central conveying unit is mounted at the axial center position of the assembling type supporting unit, the central conveying unit is composed of parallel rotating guide rails, a synchronous belt type lifting mechanism, a shaft support type rotating mechanism and a conveying table, a laser distance measuring sensor is fixedly mounted at one side end part of the conveying table, a reflecting plate is mounted at the end part of each bicycle storage rack, and the signal output end of the laser distance measuring sensor is connected to a control system. The underground bicycle garage can complete grabbing, lifting, accurate rotation and pushing of bicycles, the bicycles can be placed on the bicycle storage racks at right positions, the quantity of the stored bicycles is large, the ground space is saved, and the underground bicycle garage is reasonable in structure, good in safety and stable and efficient in operation.

Description

technical field [0001] The invention belongs to a bicycle storage garage, and in particular relates to an underground bicycle garage with an accurate angle control of a rotating mechanism. 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 loc...

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 rotation structure angle control method of the lifting table is not good enough
