Description

Technical Field

[0001] This utility model relates to the field of hoisting device technology, and more specifically, to a reactor hoisting device. Background Technology

[0002] A reactor is a device that enables a reaction process and is widely used in chemical, oil refining, and metallurgical industries. Reactors are used to realize single-phase liquid reaction processes and multiphase reaction processes such as liquid-liquid, gas-liquid, liquid-solid, and gas-liquid-solid. When installing a reactor, a crane is usually used to lift it.

[0003] In practical use, the traditional method of binding and suspending reactor branch pipes with steel wire ropes will generate huge local stress on the reactor branch pipes. During the hoisting process, the shaking of the reactor will act on the reactor branch pipes, causing damage to the reactor surface coating and affecting the subsequent service life of the reactor. Utility Model Content

[0004] In order to overcome the above-mentioned defects of the prior art, the present invention provides a reactor hoisting device to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: A reactor hoisting device includes a positioning ring, with multiple top rings fixedly connected to the top of the positioning ring. A lifting ring is provided on the outer side of the top ring, and a lifting rope is fixedly connected to one side of the lifting ring. A second lifting ring is fixedly connected to one end of the lifting rope. A positioning mechanism is provided at the bottom of the positioning ring. The positioning mechanism includes two fixed seats, the upper surface of which is fixedly connected to the bottom of the positioning ring. Two second lifting ropes are fixedly connected to the bottom of the fixed seats. A limit ring is fixedly connected to the bottom end of the second lifting rope. A first pad is fixedly connected to the inner side of the limit ring. A positioning pressure plate is provided inside the limit ring. Two guide rods are fixedly connected to the outer side of the positioning pressure plate. The outer side of the guide rods is slidably connected to the inner side of the limit ring. A second pad is fixedly connected to the inner side of the limit ring. A bolt is threadedly connected to the inner side of the limit ring. A turntable is fixedly connected to the end of the bolt. The outer side of the turntable is rotatably connected to the inner side of the second pad. An edge limiting mechanism is provided on the lower surface of the positioning ring.

[0006] By adopting the above technical solution, the positioning pressure plate and the pad ring that can be raised and lowered inside the two limiting rings are used to fit and position the edge of the reactor branch pipe, so as to maintain a uniform lifting force on the reactor branch pipe and avoid stress concentration, which would cause the branch pipe to wear and scratch.

[0007] As a further description of the above technical solution: the edge limiting mechanism includes multiple fixed rods, one end of each fixed rod is fixedly connected to the lower surface of a positioning ring, and the other end of each fixed rod is fixedly connected to a second positioning ring. Multiple insert plates are slidably connected to the inner side of the second positioning ring, and multiple insertion holes are opened on the inner side of each insert plate. An arc-shaped support plate is fixedly connected to one end of each insert plate, and a pad is fixedly connected to one side of the arc-shaped support plate. The arc-shaped support plates are arranged in a circular array on the inner side of the second positioning ring, and multiple bolts are inserted into the inner side of the second positioning ring. The outer side of each bolt is inserted into the inner side of the insertion hole.

[0008] By adopting the above technical solution: using multiple insert plates, arc-shaped support plates and pads to compress and support the outer reinforcing ribs of the reactor, and performing secondary positioning of the middle section of the reactor, in conjunction with the positioning of two pad rings, the stability of the reactor hoisting is maintained.

[0009] The technical effects and advantages of this utility model are as follows: By setting up a positioning mechanism, compared with the existing technology, the reactor branch pipe is squeezed and fitted by two limiting rings, a gasket ring, a positioning pressure plate and a guide rod. This can directly and evenly transfer the force to the reactor itself, avoid stress concentration, prevent the hanging rope from directly contacting and squeezing the polished outer wall or expensive insulation layer of the reactor, prevent scratches or indentations on the reactor body, and effectively maintain the service life of the reactor. By setting up an edge limiting mechanism, compared with the existing technology, the multi-point supported arc-shaped support plate and pad strip can squeeze and lift the edge of the reactor reinforcing rib, so that the middle section of the reactor can be further positioned, making the hoisting of the reactor more stable.

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] The embodiments disclosed in this application are as follows: Figures 1-6 The reactor hoisting device shown includes a positioning ring 1, with multiple top rings 2 fixedly connected to the top of the positioning ring 1. A lifting ring 3 is located on the outer side of each top ring 2. A lifting rope 4 is fixedly connected to one side of each lifting ring 3, and a second lifting ring 5 is fixedly connected to one end of each lifting rope 4. A positioning mechanism is located at the bottom of the positioning ring 1. The positioning mechanism includes two fixed seats 6, the upper surface of which is fixedly connected to the bottom of the positioning ring 1. Two second lifting ropes 7 are fixedly connected to the bottom of each fixed seat 6. A limit ring 8 is fixedly connected to the bottom end of each second lifting rope 7. A pad ring 9 is fixedly connected to the inner side of the limit ring 8. A positioning pressure plate 10 is located inside the limit ring 8, and two guides are fixedly connected to the outer side of the positioning pressure plate 10. Rod 11, guide rod 11 is slidably connected to the outer side of the limiting ring 8 and the inner side of the limiting ring 8 is fixedly connected to the inner side of the limiting ring 8. Bolt 13 is threadedly connected to the inner side of the limiting ring 8 and the end of bolt 13 is fixedly connected to the turntable 14. The outer side of the turntable 14 is rotatably connected to the inner side of the second pad ring 12. The lower surface of the positioning ring 1 is provided with an edge limiting mechanism. The bolt 13 is used to raise and lower the thread on the inner side of the limiting ring 8, pushing the positioning pressure plate 10 and the second pad ring 12 to cooperate with the pad ring 9 on the inner side of the limiting ring 8 to fit and position the upper and lower sides of the reactor branch pipe. This avoids the lifting rope directly squeezing the reactor branch pipe, avoids stress concentration, and maintains the safety of the reactor hoisting.

[0019] Reference Figure 2 and Figure 4As shown, the edge restraint mechanism includes multiple fixed rods 15. One end of the fixed rod 15 is fixedly connected to the lower surface of the positioning ring 1, and the other end of the fixed rod 15 is fixedly connected to the positioning ring 2 16. Multiple insert plates 17 are slidably connected to the inner side of the positioning ring 2 16. Multiple insertion holes 20 are opened on the inner side of the insert plates 17. An arc-shaped support plate 18 is fixedly connected to one end of the insert plate 17. A pad 19 is fixedly connected to one side of the arc-shaped support plate 18. The arc-shaped support plates 18 are arranged in a ring array inside the positioning ring 2 16. Multiple bolts 21 are inserted into the inner side of the positioning ring 2 16. The outer side of the bolts 21 is inserted into the inner side of the insertion holes 20. By using multiple retractable insert plates 17, arc-shaped support plates 18 and pads 19, the edge reinforcing ribs of the reactor can be squeezed and lifted at multiple points, the middle section of the reactor can be positioned twice, and the branch pipes of the reactor can be initially positioned, making the reactor more stable during hoisting.

[0020] The working principle of this utility model is as follows: When hoisting the reactor, firstly, the positioning ring 16 is fitted onto the outside of the reactor, so that one side of the positioning ring 16 is close to the reinforcing rib on the outside of the reactor. Then, the two limiting rings 8 are fitted onto the surface of the outer branch pipe of the reactor. Then, the operator screws the bolt 13 into the inner side of the limiting ring 8 for threaded lifting and lowering. Through the rotation of the turntable 14 at the end of the bolt 13 into the inner side of the pad ring 12, the bolt 13 pushes the positioning pressure plate 10 to move up and down inside the limiting ring 8. At the same time, the two guide rods 11 on the outside of the positioning pressure plate 10 slide and guide the inner side of the limiting ring 8, so that the pad ring 12 on the inner side of the positioning pressure plate 10 presses against the upper surface of the outer branch pipe of the reactor, and cooperates with the pad ring 9 on the inner side of the limiting ring 8 to press against the lower surface of the outer branch pipe of the reactor. The compression process allows the two limiting rings 8 to position the two outer branch pipes of the reactor. Then, multiple insert plates 17 on the outer side of the positioning ring 16 are positioned sequentially, causing the insert plates 17 to drive the arc-shaped support plates 18 to support the bottom surface of the outer reinforcing ribs of the reactor. The corresponding bolts 21 are then inserted into the positioning ring 16 and the insert plates 17, and the insert plates 17 are positioned through the corresponding insertion holes 20. The bottom end of the bolts 21 is then threaded with nuts, allowing the multiple arc-shaped support plates 18 and the pads 19 to compress and position the outer reinforcing ribs of the reactor, thereby achieving multi-point positioning of the reactor and ensuring the stability of the reactor hoisting. Finally, the lifting ring 5 is connected by external hoisting equipment, and the positioning ring 11 and the reactor are hoisted by multiple lifting ropes 4, lifting ring 3, and top ring 2.
