Description

Technical Field

[0001] This utility model relates to the field of cranes, and in particular to a large combined structure refrigeration box. Background Technology

[0002] A crane is a multi-action lifting machine that vertically lifts and horizontally moves heavy objects within a certain range; it is also called an overhead crane, gantry crane, or hoist. The boom is a very important component of a crane; it supports the lifting weight of containers and gives the loading and unloading bridge a certain lifting height and width.

[0003] A crane boom, also known as a jib or jib, is a bi-directionally bent metal structure that supports the lifting rope, lifting device, or luffing trolley. It is supported by connecting pins, wire ropes, or hydraulic cylinders on the crane's turntable or tower. For booms that can tilt, the luffing mechanism changes their angle of inclination to alter the crane's amplitude and lifting height. Horizontal booms change their amplitude by having a luffing trolley move back and forth on them. Based on structure, they are classified as truss booms and box-type booms; based on function, they are classified as crane booms, main booms, auxiliary booms, telescopic booms, folding booms, gooseneck booms, etc.

[0004] The copper bushing on the crane boom serves to connect the boom and the chassis, and is also a crucial component for reducing wear and friction between the two. To ensure the proper functioning of the copper bushing, regular maintenance is required, including cleaning, lubrication, and replacement. When replacing new copper bushings, it's unavoidable that freshly manufactured bushings are delivered to the site for installation, or that the bushings have been exposed to high temperatures during transport. This can cause the copper bushing to reach a high temperature, which may not be immediately apparent on the surface. If maintenance personnel touch the bushing under these conditions, they could suffer burns, posing a safety hazard. Utility Model Content

[0005] The technical problem to be solved by this utility model is to provide a large-scale combined structure refrigeration box that can conveniently cool the copper sleeve of the crane boom on the construction site.

[0008] A lid that fits into the main body of the box. The height of the upper end of the inner box and the first heat insulation cotton layer is lower than the height of the upper end of the outer box, thus forming a placement groove for placing the lid. The bottom end of the lid is supported on the inner box and the first heat insulation cotton layer. A horizontally extending support section is also provided at the top of the lid, and the support section is supported on the upper surface of the outer box. A second heat insulation cotton layer is also provided at the bottom of the lid.

[0009] Furthermore, the inner box is also provided with several partitions that divide the entire cavity into multiple placement chambers, and mounting channel steel for installing the partitions is also provided on the inner wall of the inner box.

[0010] Furthermore, the top of the lid is provided with a handle, which is in the shape of an inverted U. The two sides of the handle are respectively mounted on the lid by a mounting base. The handle has a horizontally outwardly extending mounting section at the side end. On the side of the two mounting bases that are adjacent to each other, there is a mounting groove for horizontally inserting and rotating the mounting section.

[0011] Furthermore, the bottom of the outer casing is provided with several parallel and stepped support channel steels.

[0012] The advantages of this utility model are as follows: The main body of the box in this utility model is composed of inner and outer boxes and a first heat insulation cotton layer, and together with the box cover and the second heat insulation cotton layer, a well-sealed heat-insulating cavity is formed. This allows the entire freezer to be frozen and then used on-site to cool down the copper sleeve, thus avoiding burns to personnel.

[0013] The retaining channel steel set between the inner and outer casings is used to maintain the gap between the inner and outer casings to accommodate the first insulation layer. It also serves to prevent the inner casing from deforming due to the weight of the copper sleeve after it is placed.

[0014] By installing partitions inside the inner casing, the cavity of the inner casing is divided into several placement chambers, which can cool multiple copper bushings at once and avoid interference between them when multiple copper bushings are being cooled, thus avoiding affecting the cooling effect.

[0015] The design of the supporting channel steel at the bottom of the outer casing is to allow the outer casing to be suspended in the air, so that the entire freezer can be lifted and moved by a forklift later. Attached Figure Description
