Description

Technical Field

[0001] The utility model belongs to the technical field of pressure vessel supports, and particularly relates to a support device for a pressure vessel during heat treatment. Background Technique

[0002] When large pressure vessels are heat-treated, in order to prevent thermal deformation during the heat treatment process, the support method adopted is a steel structure saddle. Since the diameters of pressure vessel equipment are different, a lot of heat treatment saddles need to be manufactured to meet the production requirements, which not only causes a large amount of capital waste and low reusability, but also occupies the workshop site.

[0003] The existing support devices for pressure vessels during heat treatment have the following disadvantages:

[0004] 1. There are many specifications of heat treatment saddles, which cannot be reused, occupying a large amount of space and capital;

[0005] 2. Due to uneven ground or manufacturing errors, when multiple heat treatment saddles are used simultaneously, the middle heat treatment saddle has a suspended phenomenon. If multiple heat treatment saddles are to be supported simultaneously, it takes a lot of time to slowly pad them up;

[0006] 3. When multiple heat treatment saddles are used simultaneously, the supporting force of each heat treatment saddle is uneven, which easily causes the deformation of the pressure vessel shell;

[0007] 4. During the heat treatment process of long and heavy pressure vessel equipment, due to thermal expansion and contraction during the heating and cooling processes, it will elongate and shorten. The heat treatment saddle is a fixed part, which will hinder the free expansion and contraction of the pressure vessel equipment, resulting in certain internal stresses during the heat treatment process of the pressure vessel equipment, and in severe cases, it will cause the deformation of the pressure vessel equipment;

[0008] Therefore, we propose a support device for a pressure vessel during heat treatment. Content of the Utility Model

[0009] The purpose of the utility model is to provide a support device for a pressure vessel during heat treatment to solve the problems raised in the above background technique.

[0010] To achieve the above purpose, the utility model provides the following technical solution: A support device for a pressure vessel during heat treatment, including a support base, wherein a plurality of movable sliding plates are movably arranged on two inner side walls of the support base, the support base is filled with support particles, and the movable sliding plates and the support particles move in the support base to form a support arc for supporting the pressure vessel.

[0011] Preferably, the upper end surface of the support base is an open structure, and the two sides of the upper end of the support base corresponding to the transverse direction of the pressure vessel are arc-shaped structures.

[0012] Preferably, at least two railing plates are arranged on the inner side wall of the support base corresponding to the arc-shaped structure. An activity space for the movement of the movable slide plate is formed between the railing plates and the inner side wall of the support base, and a plurality of the movable slide plates are inserted between the railing plates and the inner side wall of the support base at equal intervals.

[0013] Preferably, the movable slide plate is a long strip-shaped metal plate.

[0014] Preferably, the support particles are filled between the support base and a plurality of the movable slide plates.

[0015] Preferably, the support particles are coarse sand.

[0016] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0017] In the present utility model, a plurality of movable slide plates are movably arranged on the two inner side walls of the support base, and support particles are filled in the support base. The movable slide plates and the support particles move in the support base to form a support arc for supporting the pressure vessel. During use, the support devices are placed at equal intervals according to the size and length of the pressure vessel, and the movable slide plates are pulled out of the support base by a certain height. Then, support particles are filled between the support base and a plurality of the movable slide plates. Next, the pressure vessel is placed on multiple support devices and slowly lowered. The support particles and the movable slide plates naturally descend under the action of the gravity of the pressure vessel and gradually fit the outer shape of the pressure vessel. Moreover, multiple support devices all fit the pressure vessel, the support force is evenly distributed, and the support effect is good, enabling the support particles and the movable slide plates to play a role in supporting the pressure vessel.
