Description

Technical Field

[0001] The utility model belongs to the technical field of heat exchanger processing, and particularly relates to a jig for hoisting baffles of a heat exchanger. Background Art

[0002] A heat exchanger is a heat exchange device that realizes the heat energy exchange of fluid media. It can not only cool the fluid media but also recover and utilize the heat energy. A baffle is a flow disturbing device installed on a heat exchange tube. Specifically, by means of a baffle, such as a baffle assembly combined into a spiral structure, when a high-temperature medium passes through the heat exchange tube, at this time, a low-temperature medium passes through the shell of the heat exchanger, and under the action of the baffle, the low-temperature medium is disturbed. On the one hand, the time for the low-temperature medium to pass through the shell of the heat exchanger is increased to improve the heat exchange efficiency. On the other hand, during the heat exchange process, the heat distribution of the low-temperature medium is made uniform, which is also used to improve the heat exchange efficiency.

[0003] During the processing of a heat exchanger, a baffle assembly is welded to a heat exchange tube to form a heat exchange structure. After the heat exchange structure needs to be lifted to the same horizontal position as the shell cavity of the heat exchanger, it is pushed into the shell cavity of the heat exchanger to complete the processing of the heat exchanger.

[0004] However, since the heat exchange tubes are arranged in a concentric distribution manner and designed with multiple layers from the inside to the outside, and the thin baffles are welded between a large number of heat exchange tubes. The heat exchange structure is not only large in size but also low in stability. Especially during the lifting process, the relatively long heat exchange tubes are fixed and welded by the baffles. Therefore, it is very easy to deform and tear the baffles after lifting.

[0005] At the same time, due to the large overall structure weight, small volume and large length, it is very difficult to assemble and push it into the shell. Summary of the Utility Model

[0006] Based on the above background, the purpose of the utility model is to provide a jig for hoisting baffles of a heat exchanger.

[0007] To achieve the above purpose, the utility model adopts the following technical solutions:

[0008] A jig for hoisting baffles of a heat exchanger includes a hoisting mechanism. The hoisting mechanism includes an end locking hoop assembly arranged front and back. The end locking hoop assembly includes a first locking hoop and a second locking hoop hinged to the first locking hoop;

[0009] The hoisting mechanism further includes a plurality of support and insertion tube structures. The support and insertion tube structures include a plurality of insertion rods respectively fixedly connected to one side end locking hoop assembly, and the support and insertion tube structures further include a plurality of insertion tubes fixedly connected to the other side end locking hoop assembly;

[0010] When the end locking hoop assemblies approach each other, the insertion rod is inserted into the insertion tube to form a bottom support;

[0011] The end locking hoop assemblies are slidably connected through sliding beams arranged at intervals on both sides.

[0012] Preferably, the insertion rod is fixedly connected to the front side walls of the first locking hoop and the second locking hoop of the end locking hoop assembly at the rear side part;

[0013] The insertion tube is fixedly connected to the rear side walls of the first locking hoop and the second locking hoop at the front side part.

[0014] Preferably, the insertion tube and the insertion rod are arc-shaped and distributed at the lower ends of the side walls of the corresponding first locking hoop and second locking hoop.

[0015] Preferably, a hinge interface is provided at the lower end of the first locking hoop, and a hinge tongue hinged in the hinge interface is fixedly connected to the lower end of the second locking hoop;

[0016] The hinge tongue and the hinge interface are hinged through a fixing pin shaft.

[0017] Preferably, the upper end of the first locking hoop and the upper end of the second locking hoop are locked through a locking structure.

[0018] Preferably, the locking structure includes convex seats integrally formed at the top positions of the first locking hoop and the second locking hoop respectively;

[0019] A locking screw is fixedly connected to the convex seat on the second locking hoop, and a card slot is provided on the convex seat on the first locking hoop; a fastening nut is threadedly connected to the locking screw;

[0020] Flip the second locking hoop until the locking screw is stuck into the card slot, and fasten the fastening nut.

[0021] Preferably, the locking structure further includes a stop pin rod slidably connected to the convex seat, and the stop pin rod penetrates through the card slot and blocks at the top of the locking screw.

[0022] Preferably, fixing seats are respectively fixedly connected to the tops of the first locking hoop and the second locking hoop, and a suspension ring is fixedly connected to the top of the fixing seat.

[0023] Preferably, push nuts are respectively threadedly connected to the front and rear ends of the sliding beam.

[0024] The utility model has the following beneficial effects:

[0025] 1. During the implementation process, when the baffle - heat exchange tube structure is supported and placed on the first locking hoops and the second locking hoops at the front and rear ends, at this time, the operator flips the second locking hoop to merge it with the first locking hoop. After flipping, the two ends of the baffle - heat exchange tube structure are supported within the annular structure formed by the second locking hoop and the first locking hoop, while the main body part of the baffle - heat exchange tube structure is supported on the insertion rods and the insertion tubes. In this way, the large - volume, long - length, and heavy baffle - heat exchange tube structure can be pushed into the shell of the heat exchanger in a stable - support state and lifted up.

[0026] 2. During the process of pushing into the shell of the heat exchanger, it is realized by pushing in sections. Specifically, after the baffle - heat exchange tube structure is pushed a certain distance, the end locking hoop assembly at one end is pushed inward and then supported on the baffle - heat exchange tube structure again. During the pushing process, the insertion rods are continuously pushed into the lumen of the insertion tubes. In this way, it is ensured that during the process of lifting and pushing the baffle - heat exchange tube structure, the baffle - heat exchange tube structure is in a full and stable support state.
