[0001] The invention belongs to the technical field of load hanging, in particular to a lifting device for boiler installation. Background Art

[0002] A boiler is an energy conversion device. The energy input to the boiler includes chemical energy and electrical energy in the fuel, and the boiler outputs steam, high-temperature water or organic heat carrier with a certain amount of thermal energy. At present, lifting equipment is required for lifting and installation of the boiler.

[0003] When existing lifting equipment is used to lift and install a boiler, the boiler is mostly mounted using a hook on a lifting rope. The lifting equipment then controls the lifting rope to lift the mounted boiler off the ground, and then lifts the boiler to the installation location for installation operations. However, during the lifting process, the boiler is connected to the lifting equipment through the lifting rope, and the lifting rope is a flexible component. Therefore, the boiler has poor stability during lifting and there is a great risk of colliding with foreign objects. Especially in a lifting environment with a relatively narrow space, the risk of the boiler colliding with foreign objects is particularly high. Summary of the Invention

[0004] In view of the above-mentioned deficiencies in the prior art, the technical problem to be solved by the present invention is to provide a lifting device for boiler installation.

[0005] In order to solve the above technical problems, the present invention provides the following technical solutions: A lifting device for boiler installation, comprising a mounting assembly, a lifting rope, an inflatable protective assembly and an inflatable assembly. One end of the lifting rope is connected to an external crane, and the other end is connected to the mounting assembly. One end of the inflatable protective component is connected to the bottom of the mounting component, and the other end extends to the side of the boiler. The inflatable component is installed at the bottom of the mounting component. When an external crane drives the mounting component upward through the lifting rope, the inflatable component is used to fill air into the inflatable protective component, so that the inflatable protective component expands outside the boiler to provide protection for the boiler during the lifting process.

[0006] As a further improvement of the present invention: the mounting assembly includes a lifting column, a support plate, a lifting auxiliary rope and a hook, The support plate is installed on the outside of the lifting column, and several groups of lifting auxiliary ropes are provided in a one-to-one correspondence with the hooks.

One end of the inflation tube is connected to the inner cavity of the piston cylinder, and the other end is connected to the inner cavity of the first support rod. One end of the piston rod extends to the inside of the piston cylinder and is telescopically matched with the piston cylinder, and the other end extends to the outside of the piston cylinder and is hingedly connected to one end of the push rod. The end of the push rod away from the piston rod is hingedly connected to the side wall of the limit plate.

[0009] As a further improvement of the present invention: an annular slide rail is fixedly provided on the bottom wall of the support plate, a slider is fixedly provided on the top of the second support rod, and the slider is slidably engaged with the annular slide rail.

[0010] As a further improvement of the present invention: a limiting assembly is also provided on the first support rod. After the second support rod is rotated from one side of the first support rod to the other side so that the plurality of flexible tubes are sleeved on the outside of the boiler, the limiting assembly is used to limit the second support rod and the first support rod to be integrated.

DETAILED DESCRIPTION

[0015] The technical solution of the present invention will be further described in detail below in conjunction with specific implementation methods.

[0016] The following describes embodiments of the present invention in detail. Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended only to explain the present invention and are not to be construed as limiting the present invention.

[0017] See also Figure 1 as well as Figure 2 This embodiment provides a lifting device for boiler installation, including a mounting assembly 10, a lifting rope 20, an inflatable protective assembly 30, and an inflatable assembly 40. One end of the lifting rope 20 is connected to an external crane (not shown in the figure), and the other end is connected to the mounting assembly 10. One end of the inflatable protective assembly 30 is connected to the bottom of the mounting assembly 10, and the other end extends to the side of the boiler. The inflatable assembly 40 is installed at the bottom of the mounting assembly 10. When an external crane drives the mounting assembly 10 to move upward through the lifting rope 20, the inflatable assembly 40 is used to fill air into the inflatable protective assembly 30, so that the inflatable protective assembly 30 expands outside the boiler to provide protection for the boiler during the lifting process.

[0018] When the boiler needs to be installed and lifted, an external crane can be used to drive the lifting rope 20 and the mounting assembly 10 to move above the boiler, and then the mounting assembly 10 can be used to mount the top of the boiler. Subsequently, the external crane tightens the lifting rope 20, thereby driving the mounting assembly 10 to move upward, and the mounting assembly 10 pulls the boiler upward together, thereby lifting the boiler off the ground and realizing the lifting of the boiler. During the upward movement of the mounting assembly 10, the inflatable assembly 40 fills air into the inflatable protective assembly 30, so that the inflatable protective assembly 30 expands on the outside of the boiler, thereby providing protection for the boiler during the lifting process to prevent the boiler from colliding with foreign objects and being damaged.

[0019] See also Figure 1 In one embodiment, the mounting assembly 10 includes a lifting column 101, a support plate 102, a lifting auxiliary rope 103 and a hook 104. The support plate 102 is installed on the outside of the lifting column 101. The lifting auxiliary ropes 103 and the hooks 104 are provided in a one-to-one correspondence in a plurality of groups. One end of the plurality of lifting auxiliary ropes 103 is connected to the bottom wall of the support plate 102, and the other end is connected to a group of the hooks 104 respectively. The end of the lifting rope 20 away from the external crane is connected to the lifting column 101, and a plurality of lifting rings corresponding to the hooks 104 are fixed on the top of the boiler.

[0020] The lifting rope 20 is controlled by an external crane to drive the lifting column 101 and the support plate 102 to move above the boiler. Then the staff hangs several hooks 104 on the corresponding lifting rings. Then the external crane tightens the lifting rope 20. The lifting rope 20 drives the support plate 102 to move upward through the lifting column 101. When the support plate 102 moves upward, the several lifting auxiliary ropes 103 are gradually straightened. After the several lifting auxiliary ropes 103 are straightened, the boiler can be driven upward with the help of the mounting effect of the several hooks 104 on the several lifting rings, so that the boiler is away from the ground.

[0021] See also Figure 1 as well as Figure 3 In one embodiment, the inflatable protective assembly 30 includes a first support rod 301, a second support rod 302, a flexible tube 303 and a protective airbag 304. The first support rod 301 and the second support rod 302 are installed at the bottom edge of the support plate 102, and the second support rod 302 can slide in a circular trajectory along the bottom wall of the support plate 102. The flexible tubes 303 are provided in a plurality of groups, one end of each of the flexible tubes 303 is connected to the first support rod 301, and the other end is connected to the second support rod 302. The flexible tubes 303 are spaced apart along the length direction of the first support rod 301 and the second support rod 302. The side wall of each group of the flexible tubes 303 is provided with a plurality of air holes (not shown in the figure), and the outside of each group of the flexible tubes 303 is provided with a plurality of protective airbags 304 corresponding to the air holes, wherein the air holes are located inside the corresponding protective airbags 304.

[0022] Initially, the first support rod 301 and the second support rod 302 are in a state of being close to each other. When the support plate 102 is moved to the top of the boiler, the first support rod 301 and the second support rod 302 are moved to the side of the boiler and remain in a vertical state. At this time, the staff can pull the second support rod 302, and the second support rod 302 slides along the bottom wall of the support plate 102 in a circular trajectory, and then rotates around the outside of the boiler. When the second support rod 302 rotates from one side of the first support rod 301 to the other side, the flexible tubes 303 are pulled and then sleeved on the outside of the boiler. At different height positions, at this time, the external crane tightens the lifting rope 20, and the lifting rope 20 drives the lifting column 101 and the support plate 102 to move upward. The inflation component 40 fills the interior of the multiple flexible tubes 303 with air. After entering the interior of the flexible tubes 303, the air can enter the interior of the multiple protective airbags 304 through the multiple air holes on the side walls of the flexible tubes 303, thereby driving the multiple protective airbags 304 to expand. The expanded multiple protective airbags 304 evenly act on different positions outside the boiler, thereby providing comprehensive anti-collision protection for the boiler during subsequent lifting.

[0023] See also Figure 2 as well as Figure 4In one embodiment, the lifting column 101 vertically passes through the support plate 102 and movably cooperates with the support plate 102. A limit plate 105 is fixedly provided at the bottom of the lifting column 101. The interior of the first support rod 301 is hollow, and one end of the plurality of flexible tubes 303 is connected to the inner cavity of the first support rod 301. The inflation component 40 includes an inflation tube 401, a piston cylinder 402, a piston rod 403 and a push rod 404. The piston cylinder 402 is fixedly installed on the bottom wall of the support plate 102. One end of the inflation tube 401 is connected to the inner cavity of the piston cylinder 402, and the other end is connected to the inner cavity of the first support rod 301. One end of the piston rod 403 extends into the interior of the piston cylinder 402 and telescopically cooperates with the piston cylinder 402, and the other end extends to the outside of the piston cylinder 402 and is hingedly connected to one end of the push rod 404. The end of the push rod 404 away from the piston rod 403 is hingedly connected to the side wall of the limit plate 105.

[0024] Initially, the limit plate 105 is located below the support plate 102 and does not contact the bottom wall of the support plate 102, and the push rod 404 is in an inclined state. When the hooks 104 are mounted on the lifting rings and the flexible tubes 303 are sleeved on the outside of the boiler, the external crane tightens the lifting rope 20, thereby driving the lifting column 101 and the limit plate 105 to move upward. After the auxiliary lifting ropes 103 are straightened, the support plate 102 stops moving upward, while the lifting column 101 continues to move upward compared to the support plate 102, thereby driving the limit plate 105 to gradually approach the bottom wall of the support plate 102. At this time, the limit plate 105 pushes the piston rod 403 with the help of the push rod 404, so that the piston rod 403 moves toward the inside of the piston cylinder 402 to The air inside the piston cylinder 402 is pressed into the first support rod 301 through the inflation tube 401, and then enters the multiple flexible tubes 303 from the first support rod 301, and finally enters the multiple protective airbags 304 through the multiple air holes on the multiple flexible tubes 303, thereby driving the multiple protective airbags 304 to expand, so as to provide anti-collision protection for the boiler during the lifting process; as the push rod 404 rotates, when the push rod 404 rotates to be relatively horizontal with the piston rod 403, the limit plate 105 acts on the bottom wall of the support plate 102, thereby driving the support plate 102 to move upward. When the support plate 102 moves upward, the boiler is pulled by the multiple lifting auxiliary ropes 103 and the multiple hooks 104, so that the boiler is away from the ground.

[0025] See also Figure 4 In one embodiment, an annular slide rail 1021 is fixedly provided on the bottom wall of the support plate 102 , and a slider 3021 is fixedly provided on the top of the second support rod 302 , and the slider 3021 slides in cooperation with the annular slide rail 1021 .

[0026] See also Figure 3In one embodiment, a limiting assembly 50 is further provided on the first support rod 301. After the second support rod 302 is rotated from one side of the first support rod 301 to the other side so that the plurality of flexible tubes 303 are sleeved on the outside of the boiler, the limiting assembly 50 is used to limit the second support rod 302 and the first support rod 301 as a whole, so that the plurality of protective airbags 304 can remain stable at the position outside the boiler when inflated, thereby preventing the inflated protective airbags 304 from separating from the outer wall of the boiler, thereby improving the anti-collision protection effect of the boiler.

[0027] See also Figure 3 In one embodiment, the limiting assembly 50 includes a sleeve 501, a connecting block 502 and a clamping block 503. The sleeve 501 is rotatably set on the outer wall of the first support rod 301. One end of the connecting block 502 is fixedly connected to the sleeve 501, and the other end is fixedly connected to the clamping block 503.

[0028] After the second support rod 302 rotates from one side of the first support rod 301 to the other side, the sleeve 501 is rotated so that the sleeve 501 rotates relative to the first support rod 301, and then the block 503 is driven to rotate through the connecting block 502, so that the block 503 is stuck outside the second support rod 302 (such as Figure 3 As shown), the second support rod 302 and the first support rod 301 are defined as one body, so as to prevent the second support rod 302 from being affected by the inflation of the protective airbag 304 and sliding in the opposite direction compared to the bottom wall of the support plate 102, thereby preventing the protective airbag 304 from detaching from the outer wall of the boiler.

[0029] In one embodiment, the block 503 may be an arc-shaped structure or a U-shaped structure, which is not limited here.

[0030] In an embodiment of the present invention, when it is necessary to install and lift the boiler, an external crane can be used to drive the lifting rope 20 and the mounting assembly 10 to move above the boiler, and then the mounting assembly 10 can be used to mount the top of the boiler. Subsequently, the external crane tightens the lifting rope 20, thereby driving the mounting assembly 10 to move upward, and the mounting assembly 10 pulls the boiler upward together, thereby lifting the boiler off the ground, and realizing the lifting of the boiler. During the upward movement of the mounting assembly 10, the inflatable assembly 40 fills air into the inflatable protective assembly 30, so that the inflatable protective assembly 30 expands on the outside of the boiler, thereby providing protection for the boiler during the lifting process, preventing the boiler from colliding with foreign objects and being damaged. Compared with the existing technology, it can provide anti-collision protection for the boiler during the lifting process, preventing the boiler from being damaged due to collision with foreign objects during lifting, and improving the safety and protection of the boiler during lifting.

Various changes can be made within the knowledge of ordinary technicians in this field without departing from the purpose of the present invention.
