Description

Technical Field

[0001] The utility model relates to the field of air compressor maintenance equipment, in particular to a core pulling device for a gas cooler of an air compressor. Background Art

[0002] An air compressor is a gas compression device. Common large centrifugal air compressors use multi-stage compression. The interstage gas needs to be cooled during the compression process, and the heat exchange effect of the gas cooler is crucial to the stable operation of the air compressor. Once the gas cooler fails or reaches its service life and needs to be replaced, the cooler core must be pulled out for maintenance. However, the cooler of a large centrifugal compressor is large in size, and the cooler core is generally more than 6 meters long. Due to the compact structure of the installation pipeline, it is difficult to pull out the cooler core and inconvenient to repair.

[0003] At present, the commonly used core pulling method is to use an overhead crane or a traveling crane to pull the core. However, the core pulling process is easy to squeeze the cooler core tube bundle and cause damage, and the cooler is very likely to bend and deform during the lifting process, affecting its use. Utility Model Content

[0004] The utility model provides a core pulling device for a gas cooler of an air compressor, aiming to solve the problem that the existing core pulling method easily causes deformation and damage of the cooler core, thus affecting the use.

[0005] To achieve its purpose, the utility model adopts the following technical solutions:

[0006] A core pulling device for a gas cooler of an air compressor comprises a guide rail, a plurality of brackets are slidably connected to the guide rail, and pulleys cooperating with the guide rail are symmetrically arranged at the bottom of the bracket; the travel direction of the guide rail is consistent with the core pulling direction of the cooler.

[0007] Furthermore, the bracket is a planar structure composed of channel steel and I-beam.

[0008] Furthermore, the bracket is symmetrically provided with connecting holes.

[0009] Further, the pulley is lockable.

[0010] Further, the length of the guide rail is greater than the length of the cooler core.

[0011] Compared with the prior art, the beneficial effects of the utility model are as follows:

[0012] 1. The core pulling device provided by the utility model is provided with a bracket movable on a guide rail to pull out the cooler core horizontally, replacing the traditional method of using an overhead crane or a traveling crane to lift the core, ensuring that the cooler core does not deviate and does not cause damage to the cooler core tube bundle, thereby improving the core pulling efficiency and the safety of maintenance.

[0013] 2. The bracket provided by the utility model is a flat structure welded from waste channel steel and I-beam, which achieves the purpose of repairing and reusing waste and meets the national requirements of energy conservation and environmental protection. The number of brackets can be increased or decreased according to the different volumes of gas coolers to ensure a smooth cooler core extraction process. The overall production is simple and can be promoted for use. BRIEF DESCRIPTION OF THE DRAWINGS

[0017] The utility model is further described below in conjunction with the accompanying drawings:

[0018] like Figure 1-2 As shown, the utility model is a core pulling device for a gas cooler of an air compressor, comprising a guide rail 1, on which three brackets 2 are slidably connected. The bracket 2 is a planar structure welded by a channel steel and an I-beam, and the I-beam is placed above the channel steel. The bracket 2 is symmetrically provided with a plurality of connecting holes 4 for further fastening the channel steel and the I-beam. Four pulleys 3 cooperating with the guide rail 1 are symmetrically provided at the bottom of the bracket 2, and the pulleys 3 can be locked to prevent the bracket 2 from moving randomly on the guide rail 1; the travel direction of the guide rail 1 is consistent with the core pulling direction of the cooler, and the length of the guide rail 1 is greater than the length of the cooler core.

[0019] When extracting the air compressor gas cooler core, first place the guide rail 1 horizontally on the ground to ensure that the direction of the guide rail 1 is consistent with the core pulling direction of the cooler core; then debug the bracket 2 so that it moves unhindered along the guide rail 1 driven by the pulley 3 to ensure that the subsequent core pulling process is smooth and does not deviate, so as to avoid the cooler core tube bundle being squeezed and damaged; finally, when the cooler is pulled out about 1m, place the cooler core on the bracket 2, install a horizontal fall chain at the end of the cooler, and use the pulley 3 of the bracket 2 to slide on the guide rail 1, so that the cooler core can be safely and smoothly extracted horizontally without damage. The number of brackets 2 can be increased or decreased according to the different volumes of gas coolers to ensure a smooth cooler core extraction process.
