Detailed Implementation

[0037] The preferred embodiments of the present invention will be described in detail below with reference to the accompanying drawings, so as to better understand the purpose, features and advantages of the present invention. It should be understood that the embodiments shown in the drawings are not intended to limit the scope of the present invention, but are only for illustrating the essential spirit of the technical solution of the present invention.

[0038] Traditional cantilever cranes typically employ a double-column structure. This structure not only increases the equipment's footprint but also limits its application in confined spaces. This invention, based on the traditional cantilever crane lifting device, eliminates the slewing function and the secondary column of the cantilever suspension device, adopting a single-column structure to achieve usability in confined spaces. Specifically, as follows... Figure 1 As shown, a single-column cantilever suspension device for waste heat recovery from a cooling bed includes a column 1, a crossbeam 2, a drive assembly 3, a moving assembly 4, and a suspension assembly 5; Figure 2 As shown, the base of column 1 is fixed to the ground by anchor bolts 8, with the bent part of the anchor bolts 8 inserted into the concrete. After the column base is leveled, it is compacted with the foundation. A crossbeam 2 is installed on column 1. The side connecting column 1 and crossbeam 2 is the lower end face of crossbeam 2. One end of the lower end face of crossbeam 2 is connected to column 1 through a connecting plate. The connecting plate has multiple rectangular holes to facilitate the installation and adjustment of column 1 and crossbeam 2. The drive assembly 3 is installed on crossbeam 2. The moving assembly 4 is installed on crossbeam 2 and is driven to slide on crossbeam 2 by the drive assembly. One end of the suspension assembly 5 is located on the lower end face of crossbeam 2, and the other end passes through the moving assembly 4 and is raised and lowered by the moving assembly 4.

[0039] As a preferred option, the crossbeam 2 is made of hollow steel. Hollow steel has structural advantages such as light weight, large span, and large lifting capacity. It is also economical, durable, stable, and easy to maintain.

[0040] In this embodiment, when in use, the column 1 is installed in a non-high temperature area, and the end of the crossbeam 2 away from the column 1, as well as the moving component 4 and the suspension component 5 are placed in the high temperature area. This installation design can not only meet the needs of hoisting objects in high temperature areas, but also prevent the cantilever hanging device from being damaged due to high temperature.

[0041] In one embodiment, a first guide rail 6 and a second guide rail are horizontally arranged on the lower end face of the crossbeam 2, and the moving component 4 slides on the first guide rail 6 and the second guide rail. The moving component 4 can slide left and right on the first guide rail 6 and the second guide rail, thereby driving the suspension component to rise and fall.

[0042] In one embodiment, the movable component 4 includes a movable base 401, a first wheel set 402, a second wheel set 404, a first pulley 403, a second pulley 405, a third wheel set, and a fourth wheel set. The movable base 401 is disposed below the first guide rail 6 and the second guide rail. A first hole is provided on one side of the middle position of the movable base 401, and a second hole is provided on the other side of the middle position of the movable base 401. The first pulley 403 is disposed in the first hole, and the second pulley 405 is disposed in the second hole. The first wheel group 402 is disposed at one end of the movable base 401 and is slidably connected to the first guide rail 6; the second wheel group 404 is disposed at the other end of the movable base 401, is on the same horizontal line as the first wheel group 402, and is slidably connected to the first guide rail 6; the third wheel group is disposed on the other side of the movable base 401 and is slidably connected to the second guide rail, and the third wheel group is disposed opposite to the first wheel group 402; the fourth wheel group is disposed on the other side of the movable base 401, is on the same horizontal line as the third wheel group, and is slidably connected to the second guide rail, and the fourth wheel group is disposed opposite to the second wheel group 404.

[0043] Optionally, the first wheel group 402 is equipped with two moving wheels.

[0044] Optionally, the second wheel group 404 is equipped with two moving wheels.

[0045] Optionally, the third wheel set has two moving wheels.

[0046] Optionally, the fourth wheel set has two moving wheels.

[0047] In one embodiment, the suspension assembly 5 includes a first chain 501 and a second chain 502; one end of the first chain 501 is connected to the lower end face of the crossbeam 2, and the other end passes through the first pulley 403; one end of the second chain 502 is connected to the lower end face of the crossbeam 2, and the other end passes through the second pulley 405.

[0048] In one embodiment, a first chain 501 passes through the bottom end of a first pulley 403 and is provided with a first hook, and a second chain passes through the bottom end of a second pulley 405 and is provided with a second hook.

[0049] As a preferred embodiment, anti-falling chains are provided at the first chain 501 and the second chain 502.

[0050] When the first, second, third, and fourth pulley groups move to the left (i.e., towards the column), the first and second pulleys also move to the left. At this time, the first chain 501 and the second chain 502 descend, thereby driving the suspended object to move to the left and downward.

[0051] When the first, second, third, and fourth pulley groups move to the right, the first and second pulleys also move to the right. At this time, the first chain 501 and the second chain 502 rise, thereby driving the suspended object to move to the right and upward.

[0052] By equipping the moving base with multiple wheel sets (i.e., the first wheel set, the second wheel set, the third wheel set, and the fourth wheel set), the moving component 4 can move smoothly and flexibly along the first guide rail 6 and the second guide rail. Furthermore, the multi-point support design improves stability during movement and reduces swaying.

[0053] Furthermore, the first chain, the second chain, the first hook, and the second hook are capable of withstanding temperatures of 500°C and above, enabling stable lifting of large materials in high-temperature areas.

[0054] This invention uses two guide rails (i.e., the first guide rail and the second guide rail) and two chains (i.e., the first chain and the second chain) to suspend objects more stably and prevent them from swaying.

[0055] In one embodiment, the drive assembly 3 includes an electric hoist 301, a first fixed pulley 302, a first movable pulley 304, a second movable pulley 305, and a second fixed pulley 303. The electric hoist 301 is fixedly mounted on one end of the upper surface of the crossbeam 2 via a mounting base; the first movable pulley 304 is located on one side of the upper surface of the crossbeam 2 and slides on the upper surface of the crossbeam 2 via a third guide rail 7. The first fixed pulley 302 is located on the other side of the upper surface of the crossbeam 2; the second movable pulley 305 is located on one side of the lower surface of the crossbeam 2 and slides on the lower surface of the crossbeam 2 via a first guide rail 6; the second fixed pulley 303 is located on the other side of the lower surface of the crossbeam 2. One end of the wire rope of the electric hoist 301 passes through the first fixed pulley 302 and the second fixed pulley 303 and connects to one end of the movable base 401; the other end of the wire rope of the electric hoist 301 passes through the first movable pulley 304 and the second movable pulley 305 and connects to the other end of the movable base 401.

[0056] This invention, designed for use in confined spaces and to reduce floor space, features a single-column structure. In operation, the column and electric hoist are installed in a non-high-temperature area, while the end of the crossbeam furthest from the column, along with the first and second guide rails, the moving assembly, and the suspension assembly, are positioned in the high-temperature area. The electric hoist drives the first, second, first, and second fixed pulleys, which in turn move the first, second, third, and fourth wheel sets along the first and second guide rails. When moving to the left, the first and second chains move downwards simultaneously, pulling the object downwards and to the left. When moving to the right, the first and second chains move upwards simultaneously, pulling the object upwards and to the right. This lifting and lowering mechanism allows for precise positioning and operation of objects during waste heat recovery, enhancing operational flexibility. This device can be used individually or in multiple units simultaneously, meeting the needs of various application scenarios.
