Description

Technical Field

[0001] The utility model relates to a hoisting installation for adding a top structure of an elevator shaft, in particular to an elevator hoisting installation structure. Background Art

[0002] In recent years, the installation of elevators has been strongly supported by the government and is highly anticipated by owners of old residential communities, and projects have been implemented in various cities. At present, the traditional installation method of steel structure shafts for installing elevators mostly adopts building block-style hoisting, which is transported to the site in several sections for assembly. This method has a disadvantage, that is, the middle section has a rope installation hole, which is more convenient for hoisting, but the top section is a closed end, and the rope cannot be removed from the inside of the shaft, so a rope plate can only be welded on the top beam, exposed outside the shaft. After the hoisting is completed, the workers remove the crane hook from the outside, and the whole operation is relatively dangerous. Therefore, the existing technology has the problem of relatively dangerous hoisting operations. Utility Model Content

[0003] The purpose of the utility model is to provide an elevator hoisting structure. The utility model has the characteristic of effectively improving safety.

[0004] The technical solution of the utility model is to add an elevator hoisting structure, including a top hoistway, a middle opening is provided on the top surface of the top hoistway, a top hoisting welding piece is provided on the edge of the middle opening, and a bolt hole is provided on the top hoisting welding piece; it also includes a hoisting tool, which is connected to the bolt hole via bolts; the hoisting tool is provided with a hoisting rope, which is connected to the crane hook.

[0005] In the aforementioned elevator hoisting structure, the hoisting tooling includes two L-shaped angle steels distributed in parallel, a rectangular reinforcement tube is provided at one end between the two L-shaped angle steels, and mounting holes and U-shaped hoisting hooks are provided on the horizontal surface of the L-shaped angle steel; an independent rectangular tube is also provided at the other end of each L-shaped angle steel, and a reinforcement rod is provided between the independent rectangular tube and the L-shaped angle steel.

[0006] In the aforementioned elevator hoisting structure, a reinforcement member is also provided between the two L-shaped angle steels.

[0007] In the aforementioned elevator hoisting structure, after the hoisting is completed and the hoisting tooling is removed, the middle opening is covered with a detachable sealing cover plate.

[0008] In the aforementioned elevator hoisting structure, a drainage outlet is also provided at the end corner of the top of the top hoistway.

[0009] Compared with the prior art, the utility model opens a middle opening at the top of the top shaft, and the lifting tool is detachably connected to the top lifting welding piece located at the outer edge of the middle opening through bolts. During lifting, it is fixed to the lifting tool through a lifting rope for lifting. After the lifting is completed, the personnel remove the lifting rope from the middle opening of the top shaft, and then remove the connecting bolts between the lifting tool and the top shaft, and then install the sealing cover plate to complete the lifting and installation of the top shaft. There is no need for workers to remove the crane hook from the outside, thereby effectively improving the safety of the lifting and installation operations; and through the setting of the sealing cover plate, the sealing and waterproof properties can also be guaranteed. In summary, the utility model has the characteristics of effectively improving safety. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0017] The present invention is further described below in conjunction with the accompanying drawings and embodiments, but they are not intended to limit the present invention.

[0018] Embodiment. Install an elevator hoisting structure, which is as follows Figure 1-6 As shown, it includes a top shaft 1, a middle opening 2 is provided on the top surface of the top shaft 1, a top lifting welding part 3 is provided at the edge of the middle opening 2, and a bolt hole 4 is provided on the top lifting welding part 3; it also includes a lifting tool 5, which is connected to the bolt hole 4 through bolts; the lifting tool 5 is provided with a lifting rope 6, and the lifting rope 6 is connected to a crane hook 7.

[0019] like Figure 2 As shown, the lifting fixture 5 comprises two parallel L-shaped angle steels 501, one end between the two L-shaped angle steels 501 is provided with a rectangular reinforcement tube 502, and the horizontal surface of the L-shaped angle steel 501 is provided with a mounting hole and a U-shaped lifting hook 503; the other end of each L-shaped angle steel 501 is also provided with an independent rectangular tube 504, and a reinforcement rod 505 is provided between the independent rectangular tube 504 and the L-shaped angle steel 501. The lifting fixture adopts the above structure, which is simple and firm.

[0020] A reinforcement member 506 is further provided between the two L-shaped angle steels 501 .
