Preferably, the tightening device includes a sleeve and a push rod that can be inserted into the inside of the sleeve and fit in a gap with the sleeve, the sleeve is fixed at the middle of each side of the rectangular platform frame, and the push rod protrudes A slide block capable of restricting the slide of the push rod relative to the sleeve tube is provided on the outer shaft of the casing, and the slide block is in interference fit with the push rod.

Preferably, reinforcing ribs are fixed to the bottom of the rectangular platform frame, and both the oblique support rods and the vertical supporting rods are fixedly connected to the rectangular platform frame through reinforcing ribs.

Preferably, the rectangular platform frame, connecting rods, diagonal support rods and vertical support rods are all made of I-shaped steel.

Preferably, the suspension ring is made of bent round steel.

As a preference, the anti-movement stopper is made of angle steel.

The beneficial effect of adopting the above-mentioned technical solution is that in the prior art, the protection of the lower layer must be removed when the upper layer of the hole is protected, and then the protective frame is erected, which is time-consuming, labor-intensive and unstable, which is not conducive to safe operation requirements. In this scheme, the supporting frame body is used to resist the inner wall of the elevator shaft at the door opening of the elevator shaft, and the upper part of the supporting frame body is fixed on the upper platform for the staff to stand and work, and a jacking device is set on the side of the platform, which is pushed against the side of the elevator shaft on the wall to prevent the entire upper platform from shaking. The device can be recycled as the floor rises, and is safe and convenient to use, more stable and reliable, and effectively reduces construction costs.

detailed description

Below in conjunction with accompanying drawing and an embodiment the utility model is described in further detail.

The utility model comprises an upper platform and a support frame body fixed on the lower part of the upper platform. The upper platform includes a rectangular platform frame 2 and a platform pattern steel plate 1 fixedly laid on the upper surface of the platform frame 2. The top of the rectangular platform frame 2 is left and right The two sides are respectively fixed with suspension rings 6, and the sides of the rectangular platform frame 2 are respectively provided with a tightening device 3 for tightening the side walls of the elevator shaft and preventing the platform from shaking; Side and parallel symmetrically arranged triangular support frame, the triangular support frame includes an oblique support rod 5 and a vertical support rod 7, the bottom end of the vertical support rod 7 is fixedly connected with the oblique support rod 5, and the left and right two A connecting rod 4 is arranged between the inclined support rods 5 on the side, and an anti-movement retaining foot 8 is provided at the bottom of the inclined support rods 5 .

Further, the tightening device 3 includes a bushing 301 and a push rod 302 that can be inserted into the bushing 301 and fits loosely with the bushing 301 , and the bushing 301 is fixed at the middle of each side of the rectangular platform frame 2 A slider 303 capable of restricting the sliding of the ejector rod 302 relative to the sleeve 301 is provided on the outer shaft of the ejector rod 302 protruding from the bushing 301 , and the slider 303 is in interference fit with the ejector rod 302 .
