In the description of the present utility model, unless otherwise stated, the meaning of "a plurality" is two or more.

[0021] As Figures 1-4 shown, a hoisting device for a factory building closing plate includes a lifting beam 1. A slideway is arranged through the lifting beam 1 along the length direction of the lifting beam 1, and the bottom of the slideway is open. Fixed plates 12 are respectively arranged at both ends of the slideway, and the fixed plates 12 are detachably installed at both ends of the lifting beam 1 through first bolts 13. Lifting lugs 11 are arranged at the top of the lifting beam 1. There are three lifting lugs 11. One lifting lug 11 is welded at the center of the lifting beam 1, and two lifting lugs 11 are symmetrically welded on both sides of the lifting beam 1 respectively.

[0022] Bearings are installed in the fixed plates 12. The left and right screw rods 2 are rotatably installed in the fixed plates 12 along the length direction of the lifting beam 1. A rotating handle 21 is arranged at one end of the left and right screw rods 2, and the rotating handle 21 is detachably installed at the end of the left and right screw rods 2 through a pin and can drive the left and right screw rods 2 to rotate. A fixed nut 22 is arranged at the center of the left and right screw rods 2. Moving blocks 3 are respectively threadedly connected to the positive and negative threads of the left and right screw rods 2. The moving blocks 3 are engaged in the slideway, and the lifting beam 1 is supported at the bottom of the moving blocks 3. When the rotating handle 21 is rotated, the moving blocks 3 on both sides move inwards or outwards synchronously, and the width between the two moving blocks 3 is adjusted synchronously to ensure that the center of gravity of the hoisting is located at the middle position of the lifting beam 1 to ensure safe hoisting.

[0023] The card slot 4 is connected to the bottom of the moving block 3. The card slot 4 includes a connecting portion provided at the upper part and a mounting groove provided at the lower part. Two parallel connecting plates 31 are welded to the bottom of the moving block 3. A second bolt 32 is provided in the connecting plate 31. The connecting portion is hinged in the connecting plate 31 through the second bolt 32. A third bolt 41 is provided in the mounting groove. The closing plate is mounted in the mounting groove through the third bolt 41. The card slot 4 is made by welding steel plates, and the card slot 4 is polished to avoid damaging the closing plate during the hoisting process. The width of the mounting portion is 8 - 12 mm greater than the thickness of the closing plate. The surfaces of the lifting beam 1, the moving block 3 and the card slot 4 are all subjected to sandblasting anti-corrosion treatment.

[0024] During installation, drill holes at the top of the closing plate, install the card slot 4 at the drilled position, and make the through hole of the card slot 4 coincide with the drilled position of the closing plate. Insert the third bolt 41 and tighten the nut to fix the closing plate on the card slot 4. During hoisting, the hook is hung on the middle lifting lug 11, lift the closing plate and hoist it to the installation position, fix the closing plate with self-tapping bolts, and remove the third bolt 41 to remove the hoisting device from the closing plate, completing the hoisting of one closing plate.

[0025] This hoisting device can be adjusted according to the width of the closing plate. When the closing plate to be hoisted is relatively narrow, the movable blocks on both sides can be moved inward by rotating the knob 21. When the closing plate to be hoisted is relatively wide, the movable blocks on both sides can be moved outward by rotating the knob 21. It can be applicable to closing plates of different widths, select an appropriate hoisting width to hoist the sealing plate, which can improve the stability and safety of the closing plate during hoisting.

[0026] When the weight of the closing plate to be hoisted is relatively large, the strength of the hoisting hole is calculated. When using two drill holes cannot meet the strength requirements and the drilled position cannot bear its own weight, the moving block 3 can be added, and four card slots 4 are used to hoist the closing plate. During addition, rotate the knob to move the two moving blocks 3 inward by a certain distance, remove the knob 21 and take off the fixing plates 12 on both sides, place the two moving blocks 3 at both ends of the lifting beam 1, rotate the fixing nut 22 from the bottom of the lifting beam 1 to thread-connect the two moving blocks 3 to the left and right screw rods 2, and then install the fixing plates 12 and the knob 21. Drill holes on the closing plate according to the distance between the card slots 4, and install the four card slots 4 at the drilled positions. According to the maximum lifting load of the crane, one hoisting device can be selected to hoist the closing plate from the middle lifting lug 11, or two cranes can be selected to hoist the fixing plates 12 from the lifting lugs 11 on both sides respectively, and the selection is made according to the specific construction situation.

[0027] After hoisting is completed, perform edge wrapping treatment at the top end of the closing plate to cover the hoisting holes on the closing plate, which will not affect the appearance of the closing plate.

[0028] The above are only the preferred embodiments of the present utility model, and do not thus limit the patent scope of the present utility model.
