The upper ends of the 4 double rocker mechanisms are connected to the central telescopic step through hinges, and the lower ends are through hinges. Connect with screw mechanism.

On the basis of the above technical solution, the double rocker mechanism includes 2 rockers, and the 2 rockers are arranged crosswise in an X shape, and are connected as a whole by a hinge.

On the basis of the above technical solution, the cross section of the rocker is rectangular.

On the basis of the above technical solution, the first telescopic step, the second telescopic step and the central telescopic step are all welded by steel plates.

Compared with prior art, advantage of the present invention is as follows:

(1) When the water level of the rainwater on the ground exceeds the limit design elevation of the backflow of the underground building, the telescopic steps of the present invention rise and fall sequentially, which can prevent the rainwater from the ground from pouring into the underground building, without affecting the normal entry and exit of people and vehicles into the underground building, and also does not affect There is no need to recalculate the ground elevation of the underground building itself, the elevation of surrounding buildings and roads, which reduces the workload of designers.

(2) The present invention adopts electric transmission, which has a high degree of automation. The telescopic steps at each entrance can be lifted and lowered synchronously, and the water retaining height is flexible, so that it can play the role of waterproofing in a timely and synchronous manner, and reduce labor costs.

(3) The transmission structure of the present invention is simple, convenient for construction and low in cost.

Detailed ways

The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

Referring to Fig. 1 and Fig. 2, the embodiment of the present invention provides a vertical lifting platform anti-flooding door applied in the waterproof field of underground buildings, including a geared motor 1, a screw mechanism 2, 4 double rocker mechanisms 3, 2 The first telescopic step 4, 2 second telescopic steps 5 and 1 central telescopic step 6, as shown in Figure 3, the 2 second telescopic steps 5 are located on both sides of the central telescopic step 6, and the two second telescopic steps 5. There are U-shaped grooves in the middle part of the side near the central telescopic step 6, and an outwardly protruding pin is provided on the middle part of the two outer sides of the central telescopic step 6, and the protrusions of the two pins are respectively inserted into two second telescopic In the U-shaped groove of step 5.
