Description

Technical Field

[0001] This utility model relates to the field of hoisting equipment technology, and in particular, to a balanced hoisting device for a combined dry and wet cooling tower heat exchanger. Background Technology

[0002] The combined dry and wet cooling tower is a significant innovation in cooling technology that has achieved remarkable progress in recent years. It combines the advantages of dry and wet cooling towers, enabling seamless switching between three operating modes. This is made possible by the coil heat exchanger and finned tube heat exchanger installed on the cooling tower. The coil heat exchanger is installed horizontally inside the cooling tower, while the finned tube heat exchanger is installed vertically at the air inlet of the cooling tower body. During operation, the ratio of dry to wet modules is dynamically adjusted according to the working conditions, which can effectively reduce the plume pollution generated by the cooling tower and achieve water conservation.

[0003] Because the aforementioned heat exchangers (i.e., coil heat exchangers and finned tube heat exchangers) are large in size and weigh 10-20 tons, they must be installed on cooling towers using hoisting methods. Traditional hoisting methods, such as single-point hoisting or simple supports, are prone to tilting or even falling due to uneven stress, posing significant safety hazards. Furthermore, different sizes of heat exchangers typically require specific hoisting equipment, increasing equipment costs and resulting in poor equipment versatility. Utility Model Content

[0004] The technical problem to be solved by this utility model is: in order to overcome the above-mentioned defects in the prior art, a safe and versatile dry-wet combined cooling tower heat exchanger balancing hoisting device is provided.

[0005] The technical solution adopted by this utility model to solve its technical problem is: a dry-wet combined cooling tower heat exchanger balancing hoisting device, including a balancing beam, adjustable connectors located on opposite sides of the bottom of the balancing beam, and shackles installed on the adjustable connectors. The balancing beam is an I-beam structure, and a hoisting point is provided at the middle of the top of the balancing beam. The two adjustable connectors are symmetrically arranged about the hoisting point and can be far apart or close to each other. The adjustable connector is a T-shaped block structure, and the adjustable connector includes a horizontal plate and a vertical plate. The horizontal plate is fixedly connected to the balancing beam by multiple vertical bolts. The shackles are fixedly connected to the vertical plate by horizontally placed plugs. The outer diameter of the plugs is much larger than the outer diameter of the bolts. The shackles are U-shaped structures used to hook the hoisting part of the heat exchanger.

[0006] Furthermore, two rows of fixing holes are provided on opposite sides of the lower surface of the balance beam, with multiple fixing holes in each row being equally spaced. Connecting holes are provided on the horizontal plate, and the bolts pass through the fixing holes and connecting holes.

[0007] Furthermore, the connecting holes on the horizontal plate are arranged in two rows, and the distance between two adjacent connecting holes in each row is equal to the distance between two adjacent fixing holes in each row.

[0008] Furthermore, the tail of the bolt passes through the bottom of the cross plate and the balance beam from bottom to top, and a locking nut is installed at the tail of the bolt. A washer is installed between the locking nut and the bottom of the balance beam.

[0009] Furthermore, the longitudinal plate has multiple through holes spaced at equal intervals along the length of the balance beam, through which the connector passes.

[0010] Furthermore, the distance between two adjacent perforations in each row is equal to the distance between two adjacent fixing holes.

[0011] Furthermore, the shackle has a U-shaped plate structure, and corresponding insertion holes are provided on the opposite side walls of the shackle. The end of the connector passes through the insertion hole and the through hole.

[0012] Furthermore, the connector has a cylindrical structure and includes an interconnected smooth rod section and a threaded section, wherein the outer diameter of the threaded section is smaller than the outer diameter of the smooth rod section. Of the two insertion holes, one is a smooth hole that mates with the smooth rod section, and the other is an internal threaded hole that mates with the threaded section.

[0013] Furthermore, an operating part is fixedly connected to one end of the smooth rod section away from the threaded section, and an operating hole is provided on the operating part.

[0014] Furthermore, the lifting point includes a fixed plate and a lifting plate connected to each other. The fixed plate is fixedly connected to the balance beam, and the lifting plate is perpendicular to the fixed plate. A lifting hole is provided at the center of the lifting plate.

[0015] The beneficial effects of this utility model are as follows: The dry and wet combined cooling tower heat exchanger balancing hoisting device of this utility model, with its I-beam structure balance beam and T-shaped block structure adjustable connector, enhances the structural strength of both, making it more reliable in use; the adjustable connectors symmetrically arranged on both sides of the balance beam and the hoisting point located in the middle of the balance beam ensure the balance when hoisting the heat exchanger, preventing the heat exchanger from tilting due to uneven force, which is beneficial for the horizontal installation of coil heat exchangers and the vertical installation of finned tube heat exchangers; at the same time, the adjustable connectors can move along the length of the balance beam, allowing the hoisting device to adapt to the hoisting needs of heat exchangers of different sizes, with wide versatility and reduced cost.

[0024] The present invention will now be described in detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, illustrating only the basic structure of the present invention, and therefore only show the components relevant to the present invention.

[0025] Please see Figures 1-4 This utility model provides a balancing hoisting device for a combined wet and dry cooling tower heat exchanger, including a balancing beam 1, adjustable connectors 2, and shackles 3. The balancing beam 1 is an I-beam structure with a hoisting point 11 at the top center. There are two adjustable connectors 2, which are respectively installed at the bottom of the balancing beam 1. The two adjustable connectors 2 are symmetrically arranged about the hoisting point 11 and can be close to or far from each other. The adjustable connectors 2 are T-shaped blocks and include mutually perpendicular horizontal plates 21 and vertical plates 22. The horizontal plates 21 are fixedly connected to the bottom of the balancing beam 1 by multiple vertical bolts 211. The shackles 3 are fixedly connected to the vertical plates 22 by horizontally placed plugs 31. The outer diameter of the plugs 31 is much larger than the outer diameter of the bolts 211. The shackles 3 have a U-shaped structure and are used to hook the hoisting part 100 of the heat exchanger.

[0026] This utility model relates to a dry-wet combined cooling tower heat exchanger balancing hoisting device. During use, the user can adjust the position of the two adjustable connecting parts 2 on the balance beam 1 according to the size of the heat exchanger to be hoisted, so that the distance between the two adjustable connecting parts 2 matches the distance between the two opposite lifting parts 100 on the heat exchanger. This adapts to the hoisting needs of heat exchangers of different sizes. Compared with the existing hoisting tools that can only meet the hoisting requirements of heat exchangers of one specification and size, this utility model has stronger applicability and greatly reduces the design and production costs of the hoisting tools.

[0027] The balance beam 1 is designed as an I-beam structure, and the adjustable connector 2 is designed as a T-block structure. This structural design allows for lightweight production of both the balance beam 1 and the adjustable connector 2 while ensuring their structural strength, preventing bending deformation, and enabling them to meet the needs of heavy-load hoisting. Simultaneously, the cross plate 21 of the adjustable connector 2 fits snugly against the lower surface of the balance beam 1, providing a sufficiently large contact area and further ensuring the reliability of the connection between the two components.

[0028] The bottom of the horizontal plate 21 and the balance beam 1 are connected by multiple vertical bolts 211, ensuring the connection strength between the two components. Furthermore, the vertical arrangement of the bolts 211 means that during operation, they are subjected to axial loads, i.e., loads in the same direction as their axis. Compared to radial loads, bolts 211 are more easily able to withstand these loads and are less prone to deformation or breakage. Additionally, the connector 31, during installation, simultaneously penetrates the vertical plate 22 and the shackle 3, thus fixing the shackle 3 to the vertical plate 22. This simple and convenient operation greatly improves installation efficiency. Moreover, the outer diameter of the connector 31 is much larger than that of the bolts 211, ensuring that the connector 31 is also less prone to deformation and breakage under radial loads, thus guaranteeing its reliability.

[0029] Multiple lifting points 100 are provided at both opposite edges of the lifting side of the heat exchanger to be lifted, and the lifting points 100 on both edges correspond one-to-one, forming multiple symmetrical lifting positions. The shackles 31 at both ends of the same balance beam 1 are hooked onto the corresponding two lifting points 100. At the same time, the hooks of the crane's slings are hooked onto the lifting points 11 of the balance beam 1 to ensure that the heat exchanger remains balanced during lifting. The lifting points 100 are cylindrical structures, and the shackles 3 pass through the cylindrical structure and are then fixed to the longitudinal plate 22 by the plug-in connectors 31. In addition, in use, the wet combined cooling tower heat exchanger balancing lifting device of this utility model is usually used in multiple units in combination to lift multiple points of the heat exchanger simultaneously, thereby ensuring the balance of the heat exchanger during the lifting process, preventing the heat exchanger from tilting, and making the use safer. The heat exchangers include coil heat exchangers that need to be installed horizontally inside the cooling tower and finned tube heat exchangers that need to be installed vertically at the air inlet of the cooling tower. The installation configurations of both can be found in the respective references. Figure 5 and Figure 6 .

[0030] In this embodiment, two rows of fixing holes 12 are provided at opposite ends of the lower surface of the balance beam 1. Each row of fixing holes 12 has multiple fixing holes 12 along the length of the balance beam 1, and the distance between any two adjacent fixing holes 12 is the same. A connecting hole 212 is provided on the cross plate 21. After the bolt 211 passes through the fixing hole 12 and the connecting hole 212, the cross plate 21 is fixedly connected to the balance beam 1. When it is necessary to adjust the position of the adjustable connector 2, simply align the connecting hole 212 with the required fixing hole 12, and then fix it with the bolt 211.

[0031] As a preferred embodiment, the connecting holes 212 on the horizontal plate 21 are in two rows, with three connecting holes 212 in each row. The distance between two adjacent connecting holes 212 in each row is equal to the distance between two adjacent fixing holes 12 in each row. In use, the user fixes the adjustable connector 2 on the balance beam 1 with six bolts 211.

[0032] Furthermore, the tail of the bolt 211 passes through the bottom of the cross plate 21 and the balance beam 1 from bottom to top. A locking nut 213 is installed at the tail of the bolt 211. A washer 214 is installed between the locking nut 213 and the bottom of the balance beam 1 to prevent loosening and ensure that the locking nut 213 has sufficient preload.

[0033] Both the horizontal plate 21 and the vertical plate 22 are flat plate structures. The vertical plate 22 is fixedly connected to the horizontal plate 21. Two rows of connecting holes 212 are symmetrically arranged on opposite sides of the vertical plate 22 to ensure that the adjustable connector 2 is subjected to uniform force. Furthermore, multiple through holes 221 are evenly spaced along the length of the balance beam 1 on the vertical plate 22. The connector 31 passes through the through holes 221 to fix the shackle 3 onto the vertical plate 22. In use, the user can connect the shackle 3 to the appropriate through holes 221 according to the actual size of the heat exchanger to achieve fine-tuning. This allows for adjustment of the shackle 3 position without moving the adjustable connector 2, greatly facilitating user operation. Furthermore, in this embodiment, the distance between two adjacent through holes 221 in each row is equal to the distance between two adjacent fixing holes 12. Understandably, in other embodiments not shown, the distance between two adjacent perforations 221 on each row of perforations 221 is less than the distance between two adjacent fixing holes 12, thereby enabling a more precise fine-tuning of the shackle 3.

[0034] In this embodiment, the shackle 3 is generally U-shaped plate structure. The two opposite side walls of the shackle 3 are provided with corresponding insertion holes 32. The end of the connector 31 passes through the insertion hole 32 and the through hole 221, so as to hook the shackle 3 onto the connector 31.

[0035] Please refer to it again. Figure 4 In this embodiment, the connector 31 has a cylindrical structure and includes a smooth rod section 311 and a threaded section 312 connected to each other. The outer surface of the smooth rod section 311 is smooth, and the outer surface of the threaded section 312 is provided with external threads. The outer diameter of the threaded section 312 is smaller than the outer diameter of the smooth rod section 311. There are two insertion holes 32, one of which is a smooth hole that mates with the smooth rod section 311, and the other is an internal threaded hole that mates with the threaded section 312. During installation, the threaded section 312 of the connector 31 is passed through the smooth hole and then threadedly connected to the threaded hole, thereby fixing the connector 31 to the shackle 3 and preventing the connector 31 from easily detaching from the shackle 3.

[0036] Furthermore, an operating part 313 is fixedly connected to one end of the bare rod section 311 away from the threaded section 312. The operating part 313 has an operating hole 314 for the user to insert a rod-shaped tool (e.g., a screwdriver). The user can rotate the connector 31 through the rod-shaped tool to screw the threaded section 312 of the connector 31 into the internal threaded hole, which greatly facilitates the user's operation.

[0037] The lifting point 11 has an inverted T-shaped structure. The lifting point 11 includes a fixed plate 111 and a lifting plate 112 that are connected to each other. The lower surface of the fixed plate 111 is attached to the upper surface of the balance beam 1 and the two are welded and fixed together. The lifting plate 112 is perpendicular to the fixed plate 111. A lifting hole 1121 is provided at the center of the lifting plate 112. The lifting hole 1121 is used to connect with the hook of the cable on the crane.

[0038] Based on the above-described preferred embodiments of this utility model, and through the foregoing description, those skilled in the art can make various changes and modifications without departing from the scope of this utility model. The technical scope of this utility model is not limited to the contents of the specification, but must be determined according to the scope of the claims.
