[0002] Large petrochemical storage tanks are petroleum containers with a capacity of 100 cubic meters or more. They are mainly composed of tank walls, tank tops, tank bottoms, and tank accessories. They are the main equipment in oil depots and are widely used in refineries, oil fields, oil depots, and other industries. They can store petroleum and chemicals safely and efficiently. They are characterized by large volume and strong pressure resistance. There are various types of storage tanks, including vertical dome-shaped oil tanks, vertical cone-shaped oil tanks, and spherical oil tanks, which can meet different storage needs.

[0003] Large petrochemical storage tanks are typically welded together on-site. First, the tank top is welded, then it is lifted and welded onto the tank body. Due to limited space, hoisting equipment such as cranes is inconvenient for lifting operations. During normal production, these large special storage tanks require regular maintenance and installation of supporting equipment and facilities, necessitating frequent hoisting operations. However, currently, there are no better hoisting equipment or methods for this purpose, leading to various problems and inconveniences in construction.

One end of the telescopic arm 9 is fixedly connected to the connecting seat 11 and the fixed frame 4. The output end of the first hydraulic cylinder 8 can drive the rotating arm 3 to rotate around the top of the main frame rod 2, so that one end of the rotating arm 3 is raised or lowered to adjust the height of one end of the rotating arm 3. The lifting platform 6 is connected to one end of the rotating arm 3 through a hoisting mechanism and a connecting rod 5 to adjust the hoisting height of the lifting platform 6. The first hydraulic cylinder 8 will also rotate with the rotating arm 3 without interfering with its rotation.

[0021] The output end of the second hydraulic cylinder 10 is connected to the telescopic arm 9 as a whole, which can drive the telescopic arm 9 to extend and retract at one end of the rotating arm 3. The telescopic arm 9 is connected to the fixed frame 4 as a whole through the connecting seat 11, and the lifting platform 6 is connected to the hoisting mechanism on the fixed frame 4, thereby changing the distance between the lifting platform 6 and the large petrochemical storage tank, and thus the position of the lifting platform 6 can be adjusted according to the radius of the large petrochemical storage tank and specific construction requirements.

[0022] The hoisting mechanism includes a rotating roller 12, a wire rope 13, a fixed base 14, and a self-locking motor 15. The rotating roller 12 is rotatably connected inside the fixed frame 4, and the wire rope 13 is wound around the outside of the rotating roller 12. The bottom end of the wire rope 13 is fixedly connected to the top end of the connecting rod 5 via the fixed base 14.

When rotating clockwise, the steel wire rope 13 on the outside of the self-locking motor 15 can drive the lifting platform 6 to move downward. When the lifting platform 6 moves to the ground, people can place the maintenance and installation equipment and facilities inside the lifting platform 6. When the self-locking motor 15 drives the rotating roller 12 to rotate clockwise, the rotating roller 12 winds up the steel wire rope 13 on its outside. The steel wire rope 13 pulls the lifting platform 6 upward, moving the maintenance and installation equipment and facilities and personnel to the top of the large petrochemical storage tank, which facilitates the construction of the top of the large petrochemical storage tank.

The base 16 has a rotating mechanism inside, which includes a rotating shaft 17, a worm gear 18, and a worm wheel 19. The rotating shaft 17 is rotatably connected inside the base 16, and the worm wheel 19 is fixedly connected to the outer side of the rotating shaft 17. The worm gear 18 is rotatably connected to one side of the base 16. The outer walls of the rotating shaft 17 and the worm gear 18 mesh with each other. The output end of the rotary motor 20 is connected to… One end of the worm gear 18 is fixedly connected, and the top end of the rotating shaft 17 is connected to the bottom end of the chassis 1.

The worm gear 18 and the worm wheel 19 mesh with each other, and the worm wheel 19 is connected to the rotating shaft 17 as a whole. Therefore, the rotating motor 20 can drive the rotating shaft 17 to rotate on the base 16. The rotating shaft 17 can drive the chassis 1 to rotate, and the lifting platform 6 will follow the chassis 1 to rotate, changing the construction position, so as to carry out construction on the top of the large petrochemical storage tank from all directions.

[0024] Both the self-locking motor 15 and the rotary motor 20 are provided with outer shells, and multiple anti-collision strips are fixed on the outer side of the shells. Both the shells and the anti-collision strips are made of alloy steel. The shells and anti-collision strips enclose the self-locking motor 15 and the rotary motor 20 and isolate them from external objects, thus protecting the self-locking motor 15 and the rotary motor 20.

[0025] The lifting device for the large petrochemical storage tank has its output end of the No. 2 hydraulic cylinder 10 connected to the telescopic arm 9, which can drive the telescopic arm 9 to extend and retract at one end of the rotating arm 3. The telescopic arm 9 is connected to the fixed frame 4 via the connecting seat 11. The lifting platform 6 is connected to the lifting mechanism on the fixed frame 4, thereby changing the distance between the lifting platform 6 and the large petrochemical storage tank. The position of the lifting platform 6 can be adjusted according to the radius of the large petrochemical storage tank and specific construction requirements. When the self-locking motor 15 drives the rotating roller 12 to rotate clockwise, the rotating roller 12 winds up the outer steel wire rope 13.
