Description

A hoisting device and hoisting method for hoisting inner patio pipelines

technical field

The invention relates to the technical field of installation of inner patio pipes or super high-rise shaft pipes in super high-rise buildings, in particular, to a hoisting device and a hoisting method for hoisting inner patio pipes.

Background technique

For the material hoisting of high-rise inner patios, traditional construction has the following options:

1. Use a large tower crane for hoisting;

2. Use a small roof tower crane to install;

3. Use an independent climbing pole to install;

The disadvantages of the above scheme are as follows:

1. Large-scale tower cranes are used for installation, the installation cost is high, and due to the high precision of pipeline installation, the requirements for tower crane conductors and tower crane drivers are high, quality control is difficult, and safety hazards are great.

2. It is installed with a small roof tower crane, and the installation control is less difficult, but the roof tower crane requires a large installation space, and the roof of the patio is generally the roof of the machine room floor, which cannot meet its installation requirements. It is difficult to install and disassemble the tower crane, and the cost is high.

3. Independent climbing poles are used for installation. The wind rope at the top of the climbing poles cannot be installed. The length of the external extension of the climbing poles is not enough.

Since the traditional construction methods cannot optimally meet the requirements for the installation of the inner patio pipes in high-rise buildings, we must find a breakthrough and carry out research and innovation on the inner patio pipe hoisting.

The inner patio enclosure is, for example, the building body of a high-rise building, so the inner edge surfaces of the four enclosures together form a hollow inner patio.

The lifting point adjustment hoist 9 and the lifting fixed pulley 10 are connected to each other, then the position of the hoist 9 can be adjusted by adjusting the lifting point, thereby moving the horizontal position of the lifting fixed pulley 10. The hoisting fixed pulley 10 is connected with the wire rope 11 again, then the position of the pipeline hanging under the wire rope 11 can be adjusted by moving the horizontal position of the hoisting fixed pulley 10.

Referring to Fig. 3, the derrick includes a vertical leg 2 perpendicular to the top surface of the inner patio enclosure 1, a horizontal longitudinal beam 3 and a horizontal crossbeam 4 arranged on the top of the vertical leg 2 and perpendicular to each other on the horizontal plane, connected with the horizontal longitudinal beam 3 and protruding The hoisting beam 5 on the inner edge of the enclosure, the vertical leg 2, the horizontal beam 3, and the horizontal beam 4 form a three-dimensional structure, the horizontal beam 3 is slightly longer than the distance between the two horizontal beams 4, and the hoisting beam 5 is It is arranged on the end of the horizontal longitudinal beam 3 slightly protruding from the horizontal beam 4 part.

Weld the super-statically indeterminate brace 6 on the bottom surface of the horizontal longitudinal beam 3 and the horizontal beam 4 to connect with the lower half of the vertical leg 2, the lower half of the vertical leg 2 refers to the part below the midpoint of the vertical leg 2, and the top surface The horizontal longitudinal beam 3 and the horizontal beam 4 are connected to the lower half of the leg 2, so that the overall structure is more stable and reliable. Similarly, the cantilevered brace 14 can also be welded on the bottom surface of the hoisting beam 5 to connect with the lower half of the leg 2 .

And, install fixed ground anchor 7 on the enclosure top in the opposite direction (that is, the opposite direction of hoisting pipeline construction) from the derrick towards the inner patio direction, and the cantilevered derrick is connected to the fixed ground anchor 7 with a hand chain hoist 8, then Transfer the hoisting load to the fixed structure to prevent the derrick from overturning and improve stability.

Between the hoisting beam 5 and the horizontal beam 4, a hoist 9 and a hoisting fixed pulley 10 connected to each other are installed, and one end of the wire rope 11 passing through the hoisting fixed pulley 10 is connected to the hoist 12, and the other end is connected to the hoisted pipeline 17 1.

D. When the pipeline is hoisted to the vicinity of the connection with the adjacent pipeline, the hoisting speed of the hoist cannot meet the accuracy requirements of the pipeline pairing during installation. Use a paired hoist to connect the lifting lugs on the upper and lower adjacent pipelines, loosen the wire rope, and adjust by traction Group the gourds to complete the pipe pairing.
