Description

Technical Field

[0001] The utility model relates to the technical field of garage equipment, in particular to an adjustable vertical circulation stereo garage overload limiter. Background Art

[0002] With economic development and the improvement of people's living standards, the number of cars has increased significantly. The number of existing parking spaces can hardly meet daily needs, resulting in parking difficulties and chaos. Especially in the core areas of cities, parking conflicts are more prominent. In order to make full use of limited ground and underground space resources and improve the surrounding environment, the development and construction of three-dimensional parking facilities has gradually been recognized and supported.

[0003] The existing driving device of the vertical circulation stereo garage includes a frame plate on the left and right sides, a driving motor is installed on one frame plate, a driving wheel is sleeved on the output shaft of the driving motor, a transmission horizontal shaft is arranged across the frame below the driving motor, a driven wheel is sleeved on the transmission horizontal shaft just below the driving wheel, the driving wheel and the driven wheel are connected by a transmission belt, gears are sleeved on the left and right ends of the transmission horizontal shaft, and a top rotating disk with a smooth radial outer peripheral surface is installed just above each gear on the top of the frame plate; large circulating chains are arranged on the left and right sides of the frame plate from top to bottom, which are wound between the top rotating disk and the gears, and a number of vehicle carriers are suspended by the large circulating chains through a number of vehicle carrier triangle plates. Since the vertical circulation stereo garage is a multi-layered setting, it carries a large number of vehicles and requires a large transmission force. When the transmission belt is subjected to a huge transmission force, the driving motor is prone to burn out. In addition, if the load on the left side of the large circulating chain is not equal to the load on the right side, under the action of gravity, the large circulating chain will drive the vehicle carrier to rotate toward the side with the heavier load, causing uncontrolled rotation of the vehicle carrier, posing a huge safety hazard.

[0004] The patent with publication number CN209924537U discloses a vertical circulation stereo garage with an overload device, including a vertical circulation stereo garage body, a supporting top plate, a supporting bottom plate and an overload detection mechanism. The vertical circulation stereo garage body includes a parking rack, the supporting bottom plate is fixedly arranged on the ground below the vertical circulation stereo garage, and the overload detection mechanism is arranged on the upper surface of the supporting bottom plate; the hydraulic cylinder arranged in the load detection mechanism can effectively prevent the garage from being damaged when a car with excessive weight enters the parking rack; the load sensor arranged in the load detection mechanism can measure the weight of the car entering the parking rack in real time, and then display whether the car weight exceeds the standard through an indicator light, thereby ensuring parking safety. The overload limiting device can only prevent cars with excessive weight from entering the parking rack, and cannot reflect the real-time load situation of the vertical circulation stereo garage as a whole.

[0005] At present, the known vertical circulation multi-story parking garage has strict load restrictions, but because the large circulating chains are in motion and need to be adjusted and tensioned during long-term use, there is a lack of effective devices for monitoring the precise load conditions of the vehicle carriers on the two large circulating chains of the vertical circulation multi-story parking garage during operation. Summary of the invention

[0006] The purpose of the utility model is to provide an overload limiter installed on a vertical circulation stereoscopic car park in view of the deficiencies in the prior art, which can adjust the tension state of the large circulating chain and accurately monitor the load condition of the vehicle carriers on the two large circulating chains of the vertical circulation stereoscopic car park at any time during operation.

[0010] The beneficial effects of the utility model are: the lifting plate can be lifted by the height-adjusting extrusion device to fully tension the large circulating chain of the vertical circulation stereo garage, which helps the drive system to be closely combined with the large circulating chain, reduces the wear of the large circulating chain during the driving process, and makes the large circulating chain drive safely, with low noise and low energy consumption. Since the large circulating chain bears the load of all vehicle carriers and their parked vehicles, and when the large circulating chain is tightened by the lifting plate, each weight sensor can accurately measure the pressure of the height-adjusting extrusion device, and the pressure of the height-adjusting extrusion device reflects the pressure of the lifting plate, and the pressure of the lifting plate reflects the weight of the large circulating chain and the vehicle carrier thereon, that is, the real load of the vertical circulation stereo garage. At least two weight sensors are installed on each frame of the circulating chain, which can monitor the load conditions of the two circulating chains of the vertical circulating stereogram parking garage at any time and transmit the load information to the control system of the vertical circulating stereogram parking garage. When abnormal load data is monitored, such as overload, unbalanced load, etc., the control system of the vertical circulating stereogram parking garage can stop the driving system of the circulating chain, thereby protecting the driving system of the circulating chain of the vertical circulating stereogram parking garage from overload and preventing safety accidents.
