[0038] Reference Figure 1 The embodiment of the present application provides a hydraulic cantilever suspension device for recovering waste heat from a cooling bed, comprising at least one set of suspension components, the suspension components comprising:

[0039] Hollow steel beam 1;

[0040] The first column 2 is provided at one end of the hollow steel beam 1;

[0041] The telescopic mechanism 3 is provided at the bottom of the hollow steel beam 1 and close to one end of the first column 2;

[0042] Trolley 4, which is provided with a suspension mechanism for suspending the cooling bed waste heat recovery heat exchanger;

[0043] The movable track 5 is arranged at the bottom of the hollow steel beam 1, away from one end of the first column 2, and arranged along the length of the hollow steel beam 1;

[0044] The telescopic mechanism 3 drives the trolley 4 to move on the moving track 5 to move the suspended cooling bed waste heat recovery heat exchanger.

[0045] Specifically, the first column 2 is used to support the hollow steel beam 1. The first column 2 is arranged perpendicular to the hollow steel beam 1. It is understood that the first column 2 can be connected to the hollow steel beam 1 via a connecting plate. The connecting plate can have a rectangular hole. By adjusting the position of the rectangular hole, the installer can easily adjust the angle or position of the hollow steel beam 1 to meet the actual needs of the site, avoid assembly problems caused by deviation, and improve installation accuracy and efficiency.

[0046] The telescopic mechanism 3 comprises a drive unit and a telescopic unit. The drive unit is mounted on the bottom of the hollow steel beam 1 via a mounting base. The mounting base is fixedly mounted on the bottom of the hollow steel beam 1, and the drive unit is fixedly mounted on the side of the mounting base. The telescopic unit is connected to the trolley 4 to drive the trolley 4 on the movable track 5. In one embodiment, the telescopic mechanism 3 utilizes a hydraulic cylinder. The hydraulic cylinder includes a hydraulic rod 31, the end of which, distal to the hydraulic cylinder, is connected to the trolley 4. The hydraulic cylinder drives the hydraulic cylinder to extend and retract, thereby driving the trolley 4 on the movable track 5.

[0047] In one embodiment, the telescopic mechanism 3 is provided with an anti-pressure relief safety device that can automatically lock the telescopic mechanism, so that the hydraulic rod does not move after the oil cylinder is depressurized, and automatically unlocks after the oil is restored.

[0048] It can be understood that the hydraulic cantilever hanging device for cooling bed waste heat recovery provided in the embodiment of the present application is also equipped with a dedicated or shared (movable) hydraulic valve station for providing the oil source power and operation control required by the device.

[0049] In one embodiment, if multiple groups of suspension assemblies work together to suspend the cooling bed waste heat recovery heat exchanger, the inlet and outlet oil pipes of the hydraulic cylinders in the multiple groups of suspension assemblies are connected in parallel to the oil outlet and return ports of the hydraulic valve station to ensure synchronous operation of multiple hydraulic cylinders.

[0050] When in use, the first column 2 and the fixed part of the telescopic mechanism 3 are installed in a non-high temperature area, and the end of the hollow steel beam 1 away from the first column 2 and the movable track 5 and the trolley 4 are set in a high temperature area. This can not only meet the use of hoisting objects in high temperature areas, but also prevent the cantilever hanging device used to hang the cold bed waste heat recovery heat exchanger from being damaged due to high temperature.

[0051] The hydraulic cantilever hanging device for waste heat recovery of the cooling bed provided in this embodiment is used to hang the waste heat recovery heat collector of the steel rolling cooling bed. The rotation function of the traditional cantilever crane is eliminated, and the heat collector can be moved forward and backward on the cooling bed. It is driven by a telescopic mechanism. The hanging arm is a hollow steel structure with light weight, large span, large lifting capacity, economy, durability, stability and easy maintenance.

[0052] In order to make the hollow steel beam more stable and to be able to hang heavier objects, the hydraulic cantilever hanging device for cooling bed waste heat recovery also includes:

[0053] The second column 6 is arranged at the bottom of the hollow steel beam 1 , close to one end of the first column 2 , and parallel to the first column 2 .

[0054] The connection method between the second column 6 and the hollow steel beam 1 can be the same as or different from the connection method between the first column 2 and the hollow steel beam 1, and can be set according to actual needs.

[0055] It is understandable that the size of the first column 2 can be increased according to actual conditions, and the second column 6 is not provided.

[0056] It can also be understood that in order to enable the hydraulic cantilever hanging device for cooling bed waste heat recovery to be stably installed at the work site, a connecting plate 21 is fixedly installed at the bottom end of the first column 2 and the second column 6, and a plurality of mounting holes are opened on the connecting plate.

[0057] In order to improve the connection stability between the upper part of the connecting plate and the side parts of the first column 2 and the second column 6, a plurality of reinforcing ribs 22 are fixedly installed between the upper part of the connecting plate and the side parts of the first column 2 and the second column 6, and the plurality of reinforcing ribs are arranged at equal angles in a circular direction around the first column 2 and the second column 6.

[0058] In one embodiment, the suspension mechanism includes:

[0059] A first chain 41, a first end of the first chain 41 is fixed to the hollow steel beam 1;

[0060] A second chain 42, a first end of the second chain 42 is fixed to the hollow steel beam 1;

[0061] A first movable pulley 43 is movably mounted on the trolley 4 and is movably connected to the first chain 41. The second end of the first chain 41 extends away from the hollow steel beam 1 after passing through the first movable pulley 43.

[0062] The second movable pulley 44 is movably arranged on the trolley 4 and is movably connected to the second chain 42 ; the second end of the second chain 42 extends in a direction away from the hollow steel beam 1 after passing through the second movable pulley 44 .

[0063] Specifically, the first chain 41 and the second chain 42 can be fixed on the hollow steel beam 1 through fixing seats respectively. One fixing seat can be used or a shared fixing seat can be used, which is not limited here.

[0064] When the trolley 4 is driven by the telescopic mechanism 3 to move in a direction away from the first column 2, the second ends of the first chain 41 and the second chain 42 move upward and in a direction away from the first column 2, that is, move closer to the hollow steel beam 1 and away from the first column 2; when the trolley 4 is driven by the telescopic mechanism 3 to move in a direction close to the first column 2, the second ends of the first chain 41 and the second chain 42 move downward and in a direction close to the first column 2, that is, move away from the hollow steel beam 1 and towards the first column 2. It is understandable that a recovery device can be provided at the fixed seat to achieve orderly recovery and winding during the extension and retraction of the first chain 41 and the second chain 42, ensuring reliable storage of the chain. It is also understandable that the recovery device can adopt a combination of chain and sprocket, a guide wheel, an automatic reel, etc., which are not limited here.

[0065] This embodiment provides a hydraulic cantilever suspension device for cooling bed waste heat recovery. Using this suspension mechanism, the cantilever crane can move the object up and down, forward and backward, without requiring movement in other directions. Furthermore, by providing two chains, a single suspension assembly can be used to stably lift large objects in high-temperature areas.

[0066] In one embodiment, the second end of the first chain 41 and the second end of the second chain 42 are both provided with a hook 45. By providing the hook 45, it is convenient to hang the suspended object, thereby improving work efficiency.

[0067] In the embodiment, each suspension mechanism is equipped with an anti-fall chain to prevent the suspended cooling bed waste heat recovery heat exchanger from falling.

[0068] In one embodiment, the trolley 4 includes:

[0069] Four support frames 46, the four support frames 46 are respectively arranged at the four corners of the side of the trolley 4 facing the hollow steel beam 1;

[0070] Four wheel sets 47, the four wheel sets 47 are slidably mounted on the support frame 46;

[0071] The suspension assembly includes two movable rails 5;

[0072] The two wheel sets 47 arranged on one side are both slidably connected to the corresponding moving rails 5.

[0073] Specifically, the wheel set 47 slides in the moving track 5 to drive the trolley 4 to move.

[0074] The number of wheels in each wheel set 47 can be designed according to the load capacity of the device.

[0075] By providing two movable rails 5 and corresponding four wheel sets 47 , the trolley 4 can run smoothly.

[0076] In order to hang larger and heavier objects, multiple cantilever crane assemblies can be used.

[0077] In one embodiment, the telescopic mechanism 3 , the first chain 41 , the second chain 42 , the trolley 4 , and the moving track 5 are all resistant to high temperatures of 500° C. or above.

[0078] Specifically, in this device, all accessories installed in the high-temperature area must be resistant to high temperatures of 500°C or above.

[0079] It can be understood that the hydraulic cantilever hanging device for cooling bed waste heat recovery provided in the embodiment of the present application can use a single set of suspension components to hang a cooling bed waste heat recovery heat exchanger, or multiple sets of suspension components can be used to hang a cooling bed waste heat recovery heat exchanger together, and the choice is made according to actual conditions.

[0080] The above are only specific embodiments of the present application, but the scope of protection of the present application is not limited thereto. Any changes or replacements within the technical scope disclosed in this application should be included in the scope of protection of the present application. Therefore, the scope of protection of the present application should be based on the scope of protection of the claims.
