Description

A large vertical heat exchanger transportation and hoisting fixture structure Technical Field

[0001] This utility model relates to a vertical heat exchanger, specifically a large vertical heat exchanger transportation and hoisting fixture structure. Background Technology

[0002] Large vertical heat exchangers are typically transported horizontally due to their height. Once on site, they are hoisted and erected using lifting lugs. However, due to their considerable weight, with a single unit weighing over 100 tons, the load-bearing capacity of the transport supports and the lifting capacity of the lifting lugs are required to be high. If the strength is insufficient, there is a risk of breakage, causing the heat exchanger to fall and threatening the surrounding safety. Summary of the Invention

[0003] The technical problem to be solved by this utility model is to provide a high-strength and high-safety transportation and hoisting fixture structure for large vertical heat exchangers.

[0004] To solve the above-mentioned technical problems, the present invention provides a large vertical heat exchanger transportation and hoisting fixture structure, including a clamp set at the front and rear of the heat exchanger, a saddle support set at the bottom of the clamp, a shaft-type lifting lug set on the front clamp, and a tail lifting lug set at the rear of the heat exchanger.

[0005] The clamp is a ring-shaped structure with an opening, and the opening is connected by a clamp connection structure.

[0006] The clamp connection structure includes clamp reinforcing plates respectively disposed at both ends of the clamp opening, and the two clamp reinforcing plates are connected by a connector.

[0007] The saddle-type support is connected to the hoop via a support connection structure.

[0008] The support connection structure includes support stiffeners respectively disposed on the saddle support and the hoop, and the two support stiffeners are connected by a connector.

[0009] The connecting component is a bolt.

[0010] It also includes a reinforcing ring located at the rear of the heat exchanger, one side of which is connected to the tail lug.

[0011] The advantages of this utility model are: the wider clamp distributes the weight of the heat exchanger, resulting in greater load-bearing capacity and enhanced safety, while minimizing deformation of the heat exchanger's outer surface during transportation; the clamp itself is not closed, but is secured through the cooperation of stiffening plates and bolts, making assembly and disassembly more convenient; the use of a saddle-type support that can be integrated with the heat exchanger provides stronger load-bearing capacity, greater stability under load, and enhanced safety during transportation; and the addition of a reinforcing ring at the rear of the heat exchanger strengthens the tail structure, further reducing the possibility of deformation during hoisting.

[0014] Figure 3 is a schematic diagram of the support connection structure of this utility model. Detailed Implementation

[0015] The following detailed description of the transportation and hoisting fixture structure for the large vertical heat exchanger of this utility model, in conjunction with the accompanying drawings and specific embodiments, will be provided in further detail.

[0016] As shown in the figure, the large vertical heat exchanger transportation and hoisting fixture structure of this utility model includes clamps 1 respectively installed at the front and rear of the heat exchanger. The clamps 1 are open annular steel plates with an opening at the top, connected by a clamp connection structure 5 for easy disassembly. The clamp connection structure 5 includes clamp reinforcing plates 6 welded to both ends of the opening of the clamp 1, and the two clamp reinforcing plates 6 are connected by bolts. The clamps 1 themselves have a relatively wide dimension to distribute the weight of the heat exchanger and prevent deformation of the outer surface of the equipment during transportation. The width of the front clamp 1 needs to be 100-200mm larger than the diameter of the pad of the subsequently installed shaft-type lifting lug 3, and the width of the rear clamp 1 needs to be 100-200mm larger than the width of the pad of the subsequently installed saddle-type support 2.

[0017] The bottom of the clamp 1 is provided with a saddle support 2 for supporting the heat exchanger during transportation via a support connection structure 7. The support connection structure 7 includes support stiffeners 8 welded to the saddle support 2 and the clamp 1 respectively, and the two support stiffeners 8 are connected by bolts.

[0018] A shaft-type lifting lug 3 is provided on the front clamp 1. The shaft-type lifting lug 3 is located on the side of the heat exchanger. A tail-type lifting lug 4 is provided at the top of the rear of the heat exchanger. The tail-type lifting lug 4 is located behind the rear clamp 1. The shaft-type lifting lug 3 and the tail-type lifting lug 4 are welded from high-strength carbon steel materials and are used to lift the heat exchanger from a horizontal position to a vertical position by the cooperation of the two.

[0019] A reinforcing ring 9 is also provided at the rear of the heat exchanger. The reinforcing ring 9 is a ring of steel plate welded to the outer surface of the heat exchanger. One side of it is welded to the tail lifting lug 4. It is used to strengthen the tail structure of the heat exchanger during the hoisting process and prevent deformation.

[0020] In actual operation, firstly, install the front and rear clamps 1 on the heat exchanger to be installed and tighten them through the clamp installation structure 5. After all components are welded, transfer the heat exchanger to the prepared saddle support 2 and tighten it through the support connection structure 7. Then it can be transported to the installation position. After it is in place, loosen the bolts on the support connection structure 7 to separate the heat exchanger from the saddle support 2 and start the hoisting operation. By cooperating with the shaft lifting lug 3 and the tail lifting lug 4, the heat exchanger can be changed from a horizontal position to a vertical position. After hoisting it to the equipment foundation, remove the clamps 1 to complete the installation.

[0021] Of course, the above description is not intended to limit the present invention, and the present invention is not limited to the examples given above. Any changes, modifications, additions or substitutions made by those skilled in the art within the scope of the present invention should also fall within the protection scope of the present invention.
