Description

Technical Field

[0001] This application belongs to the field of detachable lifting lug technology, and particularly relates to a lifting lug for a combined reactor. Background Technology

[0002] When hoisting the reactor, in addition to the fixed lifting lugs on the top or side of the reactor, other locations on the reactor are needed as auxiliary hoisting positions to ensure the stability of the reactor during hoisting and to share the tension of the hoisting ropes at the fixed lifting lugs. Currently, the auxiliary hoisting positions are the connecting pipes, inlet and outlet steam pipes, or sensor mounting pipes fixed on the side of the reactor. Since the inlet and outlet steam pipes and sensor mounting pipes are relatively thin and have low strength, their stability during hoisting is poor. Therefore, the connecting pipes are mainly selected as auxiliary hoisting positions. However, there may be interference from the inlet and outlet steam pipes and sensor mounting pipes above the connecting pipes, or interference from the steam pipes arranged around the periphery of the reactor. In addition, the connecting pipes are hollow tubes with low strength. As auxiliary hoisting positions, the hoisting strength and position arrangement of the connecting pipes need further improvement. Utility Model Content

[0003] In order to solve the above problems, this application provides a lifting lug for a combined reactor.

[0004] The purpose of this application is to provide a lifting lug for a combined reactor. The lifting lug of this application increases the length of the auxiliary lifting position on the reactor, avoids interference from other pipe openings, and the connecting hook on the connecting rod on the lifting lug can cooperate with the hook on the lifting rope to achieve the purpose of auxiliary lifting of the reactor.

[0005] To achieve the purpose of this application, the technical solution of this application is as follows:

[0007] Furthermore, the fixed plate and the connecting flange are fixed together with bolts.

[0008] Furthermore, the connecting flange is provided with a groove, and the fixing plate is arranged in the groove.

[0009] Furthermore, the connecting hook includes a hook body, and a disassembly rod is provided at the upper end of the hook body.

[0010] Furthermore, the disassembly rod includes a rod body, one end of which is a threaded end, and the other end of which is a stop. A locking nut is provided on the threaded end.

[0011] Furthermore, a wear-resistant bushing is provided on the outer periphery of the hook body.

[0028] Example 1

[0029] like Figure 3 As shown, this embodiment is a combined reactor lifting lug 40. The lifting lug is applied to the reactor 10. The inlet and outlet steam pipes, sensor installation pipes and other pipes on the reactor 10 are not suitable as lifting auxiliary positions due to the thinness of the pipes. Therefore, when the reactor 10 is lifted, the fixed lifting lug 20 is used as the core lifting position, and the connecting pipe 30 for connecting materials can be used as a lifting auxiliary position.

[0030] like Figures 1-2 As shown, this embodiment includes a support rod 1, and a fixing plate 2 is fixedly installed at the end of the support rod 1. In one embodiment, the fixing plate 2 has a central through hole, the support rod 1 passes through the central through hole of the fixing plate 2, and the fixing plate 2 is fixed to the support rod 1 by welding. In another embodiment, the fixing plate 2 does not have a central through hole, and is fixed to the end of the support rod 1 by welding. The fixing plate 2 has edge through holes around its perimeter.

[0031] In this embodiment, a blocking plate 3 is installed on one side of the fixed plate 2, and a connecting rod 4 is arranged between the blocking plate 3 and the fixed plate 2. In one embodiment, the support rod 1 passes through the central through hole of the fixed plate 2 and makes the support rod 1 protrude a part of the fixed plate 2. The connecting rod 4 is a part of the support rod 1, but is separated by the fixed plate 2. In another embodiment, the connecting rod 4 is welded to the end of the fixed plate 2.

[0032] In this embodiment, the fixed plate 2 is preferably designed with a central through hole, and the support rod 1 and the connecting rod 4 are made as a single rod, which results in higher strength.

[0033] In this embodiment, a connecting hook 5 is movably mounted on the connecting rod 4. The connecting hook 5 serves as a hook lifting position. Specifically, the connecting hook 5 includes a hook body, and the upper end of the hook body has a connecting block. The connecting block is integrally formed with the hook body and has a through hole. A disassembly rod is installed on the upper end of the hook body. The disassembly rod includes a rod body, one end of which is a threaded end, and the other end of which is a stop. Specifically, the rod body passes through the through hole on one connecting block, and the threaded end protrudes from the other connecting block. A locking nut is installed on the threaded end, so that the stop and the locking nut are arranged on the outside of the connecting block. In addition, to avoid direct contact between the hook body and the connecting rod 4, which would cause wear on the hook body and the connecting rod 4, this embodiment has a wear-resistant bushing 6 installed on the outer periphery of the hook body. The wear-resistant bushing 6 separates the connecting hook 5 and the connecting rod 4, and the inner periphery of the wear-resistant bushing 6 has an anti-slip layer.

[0034] As a connection scheme, in this embodiment, a connecting flange 7 is movably installed on the support rod 1. For connecting discs on connecting pipes 30 of different sizes, this embodiment can replace connecting flanges 7 of different sizes, or use a support rod 1 of the same diameter corresponding to a connecting flange 7 of the same size. Through this combination scheme, important components such as connecting hooks 5 and connecting flanges 7 can be replaced. As a connection scheme between the fixing disc 2 and the connecting flange 7, the connecting flange 7 has two different sets of edge through holes. One set of edge through holes mates with the edge through holes on the fixing disc 2, and the other set of edge through holes mates with the through holes on the connecting disc. The fixing disc 2 and the connecting flange 7 are fixed together by bolts. A groove is provided on the connecting flange 7, and the fixing disc 2 is arranged in the groove.

[0035] In this embodiment, the support rod 1 is inserted into the connecting pipe 30 of the reactor 10. The inner circumference of the connecting pipe 30 is clearance-fitted with the outer circumference of the support rod 1. However, the diameter of the support rod 1 should be approximately close to the inner circumference of the connecting pipe 30. The clearance fit is only for the two to be connected quickly. The flange on the connecting pipe 30 is fixed to the connecting flange 7 by bolts, thereby connecting the combined reactor lifting lug 40 of this embodiment to the reactor 10. After the lifting is completed, the combined reactor lifting lug 40 is disassembled and recycled.

[0036] The above are merely preferred embodiments of this application and are not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.

[0037] While the specific embodiments of this application have been described above in conjunction with the accompanying drawings, this is not intended to limit the scope of protection of this application. Those skilled in the art should understand that various modifications or variations that can be made by those skilled in the art without creative effort based on the technical solutions of this application are still within the scope of protection of this application.
