Description

Technical Field

[0001] This utility model relates to the field of pipeline construction technology, and in particular to a hoisting tool for installing air conditioning ducts. Background Technology

[0002] Modern buildings typically have basements. Considering factors such as noise from air conditioning rooms, these rooms are usually located in the basement. The air conditioning pipes in these rooms are large-diameter pipes and are installed in a relatively concentrated manner. These pipes are laid along the bottom of concrete beams. Due to the limitations of basement height and space, the installation space is narrow. The existing method of pipe hoisting and installation mainly involves setting up multiple temporary lifting lugs on the basement ceiling, fixing the temporary lifting lugs with expansion bolts, and using a hand-operated hoist to vertically hoist or obliquely pull each segment of steel pipe to install the steel pipe onto the concrete beam on the ceiling.

[0003] The existing pipe hoisting and installation methods have the following shortcomings:

[0004] 1) A large number of temporary lifting points need to be set up, and the temporary lifting lugs are fixed with expansion bolts. A considerable number of expansion bolts are required, resulting in a large workload, high labor intensity, and low work efficiency.

[0005] Using hands

[0006] 2) Using a manual hoist for vertical pipe lifting is a time-consuming and labor-intensive installation method;

[0007] 3) Installing pipes using a diagonal bracing method, especially with large-angle diagonal bracing in narrow working spaces, can easily lead to damage to the lifting points;

[0008] 4) The segmented steel pipes are installed by tilting or pulling at an angle, which may cause the pipes to fall and lead to safety accidents. This also presents problems such as high construction safety risks and high labor intensity. Utility Model Content

Detailed Implementation

[0038] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0039] like Figure 1-7 As shown, Embodiment 1 of this utility model provides a lifting tool for installing a pipe 7, including a lifting tool for installing the pipe 7 onto a lifting bracket. The lifting bracket is fixed to a concrete beam 51 of the floor slab 5. The lifting bracket includes a first hanger 3 and a second hanger 4, which are symmetrically fixed to the concrete beam 51. The lifting tool includes a movable lifting structure 1, a balance limiting structure 2 cooperating with the movable lifting structure 1, and a cable structure 6 cooperating with the movable lifting structure 1. The movable lifting structure 1 includes a lifting belt 14, a forklift 11, and forks 12 and fork teeth 13 mounted on the forklift 11. A hydraulic cylinder 111 is fixed on the forklift 11, and one end of the hydraulic cylinder 111 is connected to the forklift 12. 12 is connected to forklift 11 via hydraulic cylinder 111. Fork teeth 13 are fixed to fork carriage 12 in the opposite direction. One end of lifting strap 14 is connected to fork teeth 13, and the other end of lifting strap 14 is used for binding pipe 7. Forklift 11 drives fork carriage 12 to lift and lower via hydraulic cylinder 111 to drive fork teeth 13 to lift and lower. Balance limit structure 2 includes balance beam 21, two sets of lifting components 22, and two limit bars 23. The two sets of lifting components 22 are symmetrically fixed to the outer sides of both ends of balance beam 21.

Fork teeth 13 of movable lifting structure 1 can be movably inserted into mounting holes of balance beam 21 and locked with them. One end of cable structure 6 is sleeved on pipe 7. The mobile lifting structure 1 of this utility model uses a forklift 11 to drive the fork frame 12 to rise and fall via a hydraulic cylinder 111, which in turn drives the fork teeth 13 to rise and fall, thereby causing the pipe 7 on the lifting belt 14 to move up and down. By using the forklift 11, fork teeth 13 and cable structure 6 in cooperation, the pipe 7 can be quickly installed on the first hanger 3 and the second hanger 4. The pipe 7 is tied with the lifting belt 14 to form a single-point lifting, which can meet the lifting height requirements, reduce the difficulty of lifting and installing the pipe 7, and improve the lifting and installation efficiency. The balance beam 21, two sets of lifting components 22 and two limit strips 23 cooperate to limit the pipe 7 tied to the lifting belt 14 on the fork teeth 13, preventing the pipe 7 from tilting when the cable structure 6 is loosened or broken. Adjusting the two sets of limit strips 23 to the same height can ensure the limiting effect of the balance beam 21 on the pipe 7.

[0040] In a specific implementation of this utility model, the cable structure 6 includes an inner cable 61 and an outer cable 62, which are spaced apart from each other with a spacing of 500mm.

The outer cable 62 is fitted onto the pipe 7 at a distance of 500mm from the end of the pipe 7, and the inner cable 61 is fitted onto the pipe 7 at a distance of 1000mm from the end of the pipe 7. The lengths of the inner cable 61 and the outer cable 62 are not less than 5m.

[0041] This invention features wheels 112 fixed to the bottom of the forklift 11, facilitating movement of the forklift 11 and its mounting frame, thereby moving the pipes 7 on the fork teeth 13. Specifically, this invention provides two fork teeth 13, which are fixed in opposite directions to the fork carriage 12. One end of the lifting strap 14 has a lifting connecting ring, which connects the lifting strap 14 to the fork teeth 13.

[0042] In this embodiment of the present invention, each lifting assembly 22 includes a conduit 221, a lifting screw 222, and a sleeve 223. The lifting screw 222 is located between the conduit 221 and the sleeve 223. The outer surface of the lifting screw 222 is threaded.

The sleeve 223 is fixed to the outside of the horizontal beam. The bottom end of the conduit 221 is connected to the limiting strip 23. A first threaded hole is provided at the bottom end of the sleeve 223. One end of the lifting screw 222 is connected to the first threaded hole at the bottom end of the sleeve 223 through a thread to realize the connection between the lifting screw 222 and the sleeve 223. A second threaded hole is provided at the top end of the conduit 221. The other end of the lifting screw 222 is connected to the second threaded hole at the top end of the conduit 221 through a thread to realize the connection between the lifting screw 222 and the conduit 221. In its specific implementation, the balance beam 21 of this utility model is a rectangular tube of 150×75×5 mm, with a length of 1600 mm and mounting holes of 450×40 mm. The lifting screw 222 is an M24 threaded rod with a length of 700 mm. The first threaded hole of the sleeve 223 has a diameter of M24 mm and a length of 100 mm. The second threaded hole of the conduit 221 has a diameter of M24 mm and a length of 250 mm. The limiting strip 23 is a 40×40×4 square tube with a length of 200 mm. This utility model welds the sleeve 223 to the outside of the horizontal beam, ensuring that the center of the sleeve 223 and the pipe 7 are on the same vertical plane. The lifting screw 222 is threadedly connected to the sleeve 223, allowing for detachable installation and convenient storage and transportation.

[0043] like Figure 2-9As shown, the first hanger 3 of this utility model includes a first hanger rod 31, a first crossbeam 32, a first fixing component 33, and a first locking member 34. The top end of the first hanger rod 31 is fixed to the concrete beam 51 of the floor slab 5 by the first fixing component 33, and the tail end of the first hanger rod 31 passes through one end of the first crossbeam 32 and is fixed to the first crossbeam 32 by the first locking member 34. The second hanger 4 includes a second hanger rod 41, a second crossbeam 42, a second fixing component 43, and a second locking member 44. The top end of the second hanger rod 41 is fixed to the concrete beam 51 of the floor slab 5 by the second fixing component 43, and the tail end of the second hanger rod 41 passes through one end of the second crossbeam 42 and is fixed to the second crossbeam 42 by the second locking member 44.

The first fixing member 332 passes through the first hanger 31, the first fixing pad 331, and the concrete beam 51 and is fixed to the concrete beam 51. The second fixing component 43 includes a second fixing pad 431 and a second fixing member 432. The second fixing pad 431 is disposed between the second hanger 41 and the concrete beam 51. The second fixing member 432 passes through the second hanger 41, the second fixing pad 431, and the concrete beam 51 and is fixed to the concrete beam 51. Specifically, the first fixing member 332 and the second fixing member 432 of this utility model can be expansion bolts, and the locking member can be bolts.

[0044] like Figure 10-11 As shown, the hoisting tool of this utility model is used for the installation of the air conditioning pipe 7 in the basement. The basement floor height is 4m. The pipe 7 is a ф325×8 steel pipe, installed against the bottom of the concrete beam 51. The length of a single pipe 7 is 9m. The distance between the first hanger 3 and the second hanger 4 is 6m. A 112t forklift is used for installation. The specific installation process is as follows:

[0045] First, the balance limiting structure 2 is fabricated. The balance limiting structure 2 consists of a balance beam 21, a limiting strip 23, a conduit 221, a lifting screw 222, and a sleeve 223. The sleeve 223 is welded to the outside of the horizontal beam so that the center of the sleeve 223 is on the same vertical plane as the air conditioning pipe 7. The lifting screw 222 is threaded to the sleeve 223, which can be disassembled and installed for easy storage and transportation.

[0046] Next, install the two fork teeth 13 in opposite directions on the fork carriage 12 of the forklift 11;

[0047] Then, the mounting hole of the balance beam 21 of the balance limiting structure 2 is passed through the fork tooth 13, and the fork tooth 13 is locked in the mounting hole of the balance limiting structure 2.

[0048] Subsequently, the pipe 7 was transported horizontally to the vicinity of the installation position. A 141t hoisting sling was used to tie the pipe 7 100mm away from the center of gravity. Two cables were installed near the hoisting point, with a spacing of 500mm between them. These were the inner cable 61 and the outer cable 62. The outermost cable 62 was 500mm away from the end of the pipe 7, and the cable length was not less than 5m.

[0049] Subsequently, forklift 11 slightly raises its fork 13, applying force to the lifting sling 14, and raising one end of pipe 7 1000mm higher than the other. The inner cable 61 is pulled, and pipe 7 is brought to a horizontal position. Forklift 11 is moved so that the end of pipe 7 furthest from the lifting point is closer to one of the support brackets. Pipe 7 is slowly raised. When pipe 7 is raised to approximately 200mm below the first support bracket 3, the tension of the inner cable 61 is slowly increased, raising the end of pipe 7 furthest from the lifting point. When the height of that end of pipe 7 exceeds the crossbeam of the first support bracket 3, forklift 11 is moved further. Pipe 7 gradually enters the crossbeam of the first hanger 3 until the end near the lifting point is also next to the second hanger 4, at which point the forklift 11 stops moving; slightly reduce the tension of the outer cable 62 to make pipe 7 horizontal, and slightly raise the fork 13 so that pipe 7 is about 100mm above the crossbeam of the hanger. Move the forklift 11 until the end of pipe 7 near the lifting point is about 900mm into the second hanger 4, then stop moving the forklift 11, pull the outer cable 62 near the beam end, and then loosen the inner cable 61 to keep pipe 7 horizontal. Move the forklift 11 again until pipe 7 is in place.

[0050] Finally, repeat the above steps to complete the installation of the remaining pipes 7.

[0051] The lifting tool of this utility model utilizes a lifting strap 14 to bind the pipe 7 near its center of gravity, creating a slightly eccentric lifting point on the pipe 7. This results in the pipe 7 being heavier at one end and lighter at the other. The cable structure 6 is fitted onto the end of the pipe 7 closest to the slightly eccentric lifting point, maintaining a certain tension on the pipe 7. This balances the torque generated by the eccentricity of the pipe 7 with the torque generated by the tension of the cable structure 6, facilitating control of the horizontal and tilt balance of the pipe 7. The other end of the cable structure 6 is operated manually from the ground, making operation convenient. The heavier end of the pipe 7 can be quickly inserted into the first support 3, facilitating adjustment of the relative position of the pipe 7 and the support for accurate positioning. To prevent accidents during lifting, this utility model's lifting... The tool is also equipped with a balance limiting structure 2, which is locked to the fork tooth 13 through the mounting hole on it, so as to realize the quick installation and removal of the balance limiting structure 2, improve the installation efficiency. The balance limiting structure 2 can also prevent the problem of excessive tilt angle when the pipeline 7 is tilted. The balance limiting structure 2 of this utility model can move up and down along the guide tube 221 through the lifting screw 222 to realize the height adjustment of each lifting component 22, which facilitates the adjustment of the height and balance of the balance beam 21, and achieves the purpose of adjusting the height of the fork tooth 13 and the lifting belt 14 on the balance beam 21, thereby realizing the purpose of adjusting the limit distance of the pipeline 7, thus adapting to the distance adjustment limit requirements of different pipeline 7 diameter specifications, and has high flexibility.

[0052] The above-disclosed embodiments are merely preferred embodiments of the present utility model and should not be construed as limiting the scope of the present utility model. Therefore, any equivalent variations made in accordance with the claims of the present utility model shall still fall within the scope of the present utility model.
