Detailed Description

For a better understanding of the present invention, the following description is given in conjunction with the accompanying drawings and examples.

As shown in figures 1-3, a ground safety protection door of a material lifter comprises side columns 1 at two sides of a protection door, a protection door plate 2 and an automatic lifting device, wherein two protection door slideways 3 are symmetrically arranged on the side columns at two sides of the protection door, two side edges of the protection door plate are arranged with the protection door slideways and slide up and down along the protection door slideways, the automatic lifting device comprises a fixed pulley 4, a steel wire rope 5, a counterweight 6, a counterweight slideway 7, a counterweight pressure rod 8 and a hanging basket pressure rod 9, the fixed pulley is fixed at the upper parts of the side columns at two sides of the protection door, the counterweight slideways are symmetrically fixed on the side columns at two sides of the protection door, the counterweight slides up and down along the counterweight slideways, the steel wire rope bypasses two ends of the fixed, the lifting basket pressing rods are arranged perpendicular to the plane of the protective door plate, symmetrically arranged on two sides of the lifting basket 10 and arranged corresponding to the balance weight pressing rods (see figure 4).

As shown in figure 5, the balance weight is composed of a deformed steel bar 11 and a square tube 12, the square tube is sleeved outside the deformed steel bar and connected through welding, a nut 13 is arranged at the top of the balance weight, the end head on one side of the steel wire rope bypasses the nut and is fastened through a fixing clamp, and a balance weight pressing rod is arranged on one side of the square tube.

The weight of the counter weight is less than the weight of the protective door plate.

The guard gate slide is by two angle steel openings syntropy settings, and welded fastening constitutes in the two right angle edges of guard gate side post, forms U type slide.

The counterweight slideway is formed by overlapping and welding two opposite sides of the openings of the angle steels to form a U-shaped slideway.

Two angle steels of the counterweight slide way have different side lengths, the angle steel with the long side length is welded with the edge column of the protective door, a gap is formed between the angle steel with the short side length and the edge column of the protective door, and the counterweight pressure rod extends out of the gap.

A use method of a ground safety protection door of a material hoister comprises the following steps:
