Description

Technical Field

[0001] The utility model relates to the technical field of lifters, in particular to an anti-top impact bracket device of a lifting platform. Background Art

[0002] A lift is a device used to transport people or goods up and down, usually in high-rise buildings, shopping malls, hospitals and other places. It consists of an electric drive system, a lift shaft, an electrical and control system, and safety equipment. The use of lifts greatly facilitates people's travel and the transportation of goods, and improves the connection efficiency between floors. However, in order to ensure the safety of passengers and goods, manufacturers and building managers should comply with relevant safety standards and regulations, and perform regular maintenance and inspections.

[0003] After searching, the patent announcement number is CN104763271A, which discloses a toothed belt lifter, including a driving mechanism and a lifter bracket, and its characteristics are: a transmission belt passive gear and a transmission belt driving gear are respectively provided at the upper and lower ends of the long strip lifter bracket, and are connected and driven by a toothed belt; a slider for installing the window glass is fixed on the toothed belt, and the slide groove of the slider is clamped on the slide rail of the lifter bracket; the transmission belt driving gear shaft is connected to the driving mechanism. The beneficial effect of the present invention is that the contact area between the lifter drive belt and the transmission gear is large, and the stress points are dispersed, thus avoiding the disadvantages of small contact area between the wire rope and the transmission wheel of the rope-type automobile window lifter, and concentrated and severe wear of the stress points. The occurrence rate of failure of the lifter during use is reduced, and the service life of the lifter is extended. In the existing technology, although a certain lifting effect can be achieved during use, the defect is that the existing lifter lacks a certain anti-top impact effect, resulting in the lifting position of the lifting plate exceeding the expected position due to some sudden reasons during the lifting process, causing it to deviate from the track, causing serious hidden dangers. In view of this, we propose an anti-top impact bracket device for a lifting platform to solve the above problem. Utility Model Content

When the moving plate moves upward, it can cooperate with the through holes to follow the lifting plate to rise and fall, ensuring that the lifting plate will not tilt in the area where it is separated from the hydraulic cylinder, affecting the subsequent stable lifting and lowering coordination effect.

[0009] Preferably, the diameter of the limiting plate is larger than the diameter of the upper half of the movable plate. Such a design can ensure the position limiting effect of the limiting plate on the lifting plate.

[0010] Preferably, grooves are symmetrically arranged on both sides of the surface of the lifting plate, and a base is arranged at the lower end of the bottom plate. The grooves can achieve a certain anti-slip effect, and the base can increase the stability of the device and reduce the propagation of noise to a certain extent.

[0011] Preferably, racks are provided on the outer walls on both sides of the mounting column, and gears are provided inside on both sides of the lifting plate. The gears are matched with the racks, and a stable rising and falling effect is achieved through the symmetrical arrangement of the gears and the racks on both sides.

[0012] Preferably, a motor is provided inside the lifting plate, and the motor is matched with the gear. The motor can drive the gear to rotate, thereby achieving the lifting and lowering effect of the lifting plate.

[0013] Compared with the prior art, the utility model has the following beneficial technical effects:

[0014] 1. This device can use the gears and racks driven by the motor to drive the lifting plate up and down from both sides. The coordination of the racks and gears symmetrically distributed on both sides can achieve a stable lifting effect;
