Description

Technical Field

[0001] The utility model relates to the technical field of stereo garages, in particular to a lifting device for a shallow foundation pit. Background Art

[0002] The pit-type stereo garage is a parking device that designs parking spaces underground, and uses a mechanical lifting system to achieve vehicle lifting and access. This design not only saves surface space, but also provides a higher parking capacity, while not affecting the urban landscape and greening on the ground. The double-layer shallow pit lifting equipment is a specific lifting system in the pit-type stereo garage, which is characterized by the lifting mechanism that allows vehicles to be accessed at different levels.

[0003] When using the shallow pit lifting equipment in the pit-type stereo garage, once the driving system fails, the vehicle loading plate will quickly fall into the pit. This will not only cause damage to the vehicle, but also cause economic losses. And if there are people in the vehicle during the falling process of the vehicle loading plate, the consequences will be even more disastrous. Therefore, a danger protection device is urgently needed to protect the property safety and life safety of users. Utility Model Content

DETAILED DESCRIPTION

[0018] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0019] Reference Figure 1-4, a shallow foundation pit lifting equipment includes a foundation pit 1 and a frame 2, the frame 2 is built inside the foundation pit 1, a driving base 21 is fixedly built at the bottom of the frame 2, and an upper vehicle loading plate 3 and a lower vehicle loading plate 30 are movably arranged above the driving base 21, the upper vehicle loading plate 3 and the lower vehicle loading plate 30 are integrated and connected by support columns 31; a plurality of limiting cavities 32 are opened on both sides of the upper vehicle loading plate 3 and the lower vehicle loading plate 30, and fixed seats 4 are arranged on both sides of the frame 2 above the foundation pit 1, and limiting members 61 are movably arranged in the fixed seats 4, and the limiting members 61 are adapted to the limiting cavities 32.

[0020] Among them, the foundation pit 1 is excavated underground, the frame 2 is built inside the foundation pit 1, the upper vehicle loading plate 3 and the lower vehicle loading plate 30 are integrated structures, which are moved up and down by the transmission between the driving base 21 and the chain, and the upper vehicle loading plate 3 and the lower vehicle loading plate 30 are connected with chains. It is also worth noting that the specific structures and working methods of the foundation pit 1, the frame 2, the driving base 21, the upper vehicle loading plate 3 and the lower vehicle loading plate 30 are all existing technologies currently disclosed on the market, which are common knowledge well known to those skilled in the art, and do not belong to the main technical problems to be solved in this technical solution, so they are not elaborated in this utility model.

[0021] The fixing seat 4 is arranged corresponding to the limiting cavity 32, and a side cavity 41 is provided on the fixing seat 4 on one side facing the limiting cavity 32, and an adjustment cavity 42 is provided at the top of the side cavity 41. The limiting member 61 is movable in the side cavity 41, and an adjustment column 6 is vertically arranged upwardly fixed at the top of the limiting member 61, and the adjustment column 6 extends out of the adjustment cavity 42. In special cases, the user can adjust the position of the limiting member 61 by pulling the adjustment column 6.

[0022] Among them, the electromagnet assembly 5 is fixedly arranged on both sides of the frame 2 above the foundation pit 1, and the electromagnet assembly 5 on each side is located behind the fixing seat 4. A magnetic part 62 is fixedly arranged behind the fixing seat 4, and when the electromagnet assembly 5 is powered on, the magnetic part 62 and the electromagnet assembly 5 are adapted to attract each other. By powering on the electromagnet assembly 5, the electromagnet assembly 5 can generate a magnetic attraction, so that the magnetic part 62 can be adsorbed backward, so that the magnetic part 62 drives the adjustment column 6 and the limiter 61 to move toward the electromagnet assembly 5.

[0023] Among them, the side of the limiter 61 facing the limiter cavity 32 and the inner wall of the limiter cavity 32 are both provided with magnetic materials, and the limiter 61 is in contact with the inner wall of the limiter cavity 32 by magnetic attraction. In this way, the limiter 61 can automatically enter the limiter cavity 32 by magnetic attraction.

[0024] In this embodiment, when the user needs to park the vehicle, the vehicle can be parked on the upper vehicle loading plate 3 or the lower vehicle loading plate 30. When the upper vehicle loading plate 3 or the lower vehicle loading plate 30 is located above the foundation pit 1, the limiter 6 will be automatically adsorbed into the limiter cavity 32 by the magnetic attraction between the limiter 6 and the limiter cavity 32. At this time, the upper vehicle loading plate 3 and the lower vehicle loading plate 30 can be fixedly supported by the clamping between the limiter 6 and the limiter cavity 32, so that they will not fall in the event of a failure.

[0025] Further, when the driving system is in a normal state and the user needs to move the upper vehicle loading plate 3 and the lower vehicle loading plate 30, the user can control the electromagnet assembly 5 to be energized. When the electromagnet assembly 5 is energized, the magnetic attraction force generated by it can be adsorbed to the magnetic member 62, so that the adjustment column 6 can drive the limiter 61 to move toward the electromagnet assembly 5. At this time, the limiter 61 can leave the limit cavity 32, so that the fixed support of the upper vehicle loading plate 3 and the lower vehicle loading plate 30 can be released.

[0026] It is worth noting that the magnetic attraction between the stopper 61 and the stopper cavity 32 is smaller than the magnetic attraction between the electromagnet assembly 5 and the magnetic member 62. Therefore, when the electromagnet assembly 5 is powered on, the magnetic attraction generated by it is greater than the magnetic attraction between the stopper 61 and the stopper cavity 32, so that the adjustment column 6 drives the stopper 61 to move toward the electromagnet assembly 5.

[0027] In the utility model, the storage and access of the vehicle can be achieved through the upper vehicle loading plate 3 and the lower vehicle loading plate 30. The upper vehicle loading plate 3 and the lower vehicle loading plate 30 can be fixedly supported by the clamping between the limiting member 61 and the limiting cavity 32, so as to prevent them from falling rapidly due to malfunction during use, thereby ensuring the property safety and life safety of the user.

[0028] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
