Technical Field

[0001] The utility model relates to the field of precision copper tube pit annealing, in particular to a rotatable copper tube coil rack. Background Art

[0002] In the existing refrigeration technology, copper tubes are often used as heat dissipation structures due to their excellent metal properties, such as heat dissipation structures in air conditioners, etc. In order to improve the performance of copper tubes, the annealing process is a common way to heat-treat copper tubes. During the annealing process, the copper tube coils are placed on a rack, and then the rack filled with copper tubes is placed in an annealing furnace for annealing treatment. Therefore, how to ensure good ventilation performance of the rack while making it more convenient to load and unload copper tubes is one of the problems that need to be considered. Therefore, it is necessary to provide a rack that is convenient for loading and unloading to overcome the above-mentioned defects. Summary of the Utility Model

[0003] The purpose of the utility model is to provide a rotatable copper tube coil rack, which is convenient for loading and unloading while ensuring good ventilation during the copper tube annealing process, and improves the operation efficiency.

[0004] According to one aspect of the utility model, a rotatable copper tube coil rack for placing copper tube coils is provided, including: an upper rack, a middle rack, and a lower rack;

[0005] The upper rack, the middle rack, and the lower rack are arranged in sequence from top to bottom. The top end of the middle rack is connected to the upper rack by bolts, and the bottom end of the middle rack is connected to the lower rack by bolts;

[0006] The upper rack includes: a first chassis, a first annular disk, a first middle column, and a first connecting column;

[0007] The first annular disk is placed on the first chassis and welded to the first chassis. The first middle column is placed in the middle of the first chassis and welded to the first chassis. The first connecting column is placed at the edge position of the first chassis and welded to the first chassis. The bottom of the first connecting column has a connecting groove and bolt holes.

[0008] The first chassis includes a support skeleton and a sliding part,

[0009] The support skeleton is a bar-shaped structure arranged in a plurality of umbrella shapes for bearing;

[0010] The sliding part is placed on the support skeleton for realizing the rotation of the first annular disk;

[0011] The sliding part includes a sliding groove, a sliding rail, and a roller. The sliding groove is an annular groove structure passing through the support skeleton. The sliding rail is an annular structure placed in the sliding groove. The first annular disk is welded to the sliding rail. The roller is placed at the bottom of the sliding rail for realizing the rotation of the sliding rail.

[0012] Through this solution, the rotation of the first annular disk, the second annular disk, and the third annular disk can be achieved. When the copper tube coil is placed on the first annular disk, the operator does not need to move along the rotatable copper tube coil rack. Only by rotating the first annular disk along the chute according to the demand, the copper tube coil can be placed into the five first annular disks respectively, improving the operation efficiency. Similarly, the second annular disk and the third annular disk can also achieve the above operations.

[0013] By designing the umbrella-shaped arranged support skeleton through this solution, the ventilation effect can be better improved, and the heat uniformity of the copper tube coil during annealing can be enhanced.

[0014] Through this solution, a three-layer rotatable copper tube coil rack including an upper layer rack, a middle layer rack, and a bottom layer rack is provided, which can improve the utilization rate of the annealing rack, thereby enhancing the efficiency of the annealing operation.

[0015] Preferably, the sliding part includes a first sliding part and a second sliding part. The second sliding part is closer to the first middle column relative to the first sliding part, and the chute and slide rail of the second sliding part have different diameters from those of the first sliding part.

[0016] By designing two sliding parts, the first annular disk can be better supported, and the stability of the first annular disk when carrying the copper tube coil can be improved.

[0017] Preferably, the middle layer rack includes: a second bottom plate, a second annular disk, a first support column, and a second middle column;

[0018] The second annular disk is placed on the second bottom plate;

[0019] The first support column is placed at the edge of the second bottom plate and includes a support part and a connection part. The connection part is located at the lower end of the support part. The connection part has a connection groove and a bolt hole for connecting the bottom layer rack. The top end of the support part has a connection hole and is bolted to the first connection column;

The outer wall diameter of the second middle column is smaller than that of the first middle column, and the upper part of the second middle column is coaxially sleeved with the first middle column.

[0021] Through this solution, by designing the connection part, the connection of different layer racks can be better achieved, and at the same time, it can be conveniently disassembled. The operator can select the number of layers of the rotatable rack according to the quantity of the copper tube coil, improving the practicability and utilization rate of the rotatable rack.

[0022] Preferably, the second bottom plate has the same structure as the first bottom plate and includes a support skeleton and a sliding part. The second annular disk is welded to the sliding part.

[0023] Preferably, the bottom layer rack includes: a third bottom plate, a third annular disk, a second support column, and a third middle column;

[0024] The third annular disk is placed on the third chassis;

[0025] The second support column is placed at the edge of the third chassis, and its top end has a connection hole which is connected to the connecting part by bolts;

[0026] The third intermediate column is placed in the middle of the third annular disk and welded to the third annular disk. The outer wall diameter of the third intermediate column is smaller than that of the second intermediate column, and the upper part of the third intermediate column is sleeved coaxially with the second intermediate column.

[0027] Preferably, the third chassis has the same structure as the first chassis.

[0028] Preferably, the height of the third intermediate column is greater than that of the first or second intermediate column. Since the overall load of the bottom layer rack is heavier, a relatively large part of the third intermediate column can be sleeved into the second intermediate column, improving the overall stability of the rotatable copper tube disk rack.

[0029] Preferably, the number of the first annular disks is five, and the numbers of the second and third annular disks are both five.

[0030] A rotatable copper tube disk rack provided by the present utility model has three-layer racks including an upper layer rack, a middle layer rack and a bottom layer rack. Each layer is designed with a support skeleton and a sliding part to realize the rotation of the first, second and third annular disks. The operator does not need to move along the rotatable copper tube disk rack, but only needs to rotate the first, second and third annular disks along the sliding grooves according to the needs, so as to place the copper tube disks into the five first, second and third annular disks respectively, improving the operation efficiency and facilitating loading and unloading while ensuring good ventilation during the copper tube annealing process.

For those of ordinary skill in the art, without creative efforts, other drawings can be obtained based on these drawings, and other embodiments can also be obtained.

[0045] See Figure 1 As shown, this embodiment provides a rotary rack for placing copper tube coils to anneal the copper tube coils.

The first annular disk 102 is welded to the sliding rail 1013. The roller 1014 is placed at the bottom of the sliding rail 1013. When the first annular disk 102 is pushed by an external force, the sliding rail 1013 can rotate along the sliding groove 1012 through the pulley, thereby realizing the rotation of the first annular disk 102.

[0048] Through this embodiment, the rotation of the first annular disk 102, the second annular disk 202, and the third annular disk 302 can be realized.

[0050] Through this solution, a three-layer rotatable copper tube coil rack including an upper layer rack 1, a middle layer rack 2, and a bottom layer rack 3 is provided, which can improve the utilization rate of the annealing rack, thereby enhancing the efficiency of the annealing operation.

[0051] Preferably, the sliding part 1010 includes a first sliding part 1010a and a second sliding part 1010b. The second sliding part 1010b is closer to the first middle column 103 relative to the first sliding part 1010a.

[0056] The second middle column 204 is placed in the middle of the second chassis 201 and is welded to the second chassis 201. The outer diameter of the second middle column 204 is smaller than that of the first middle column 103, and the upper part of the second middle column 204 is coaxially sleeved with the first middle column 103.

[0057] Through this solution, by designing the connection part 2032, the connection of different layer racks can be better achieved, and at the same time, it can be easily disassembled. The operator can select the number of layers of the rotatable rack according to the quantity of the copper tube coil, improving the practicability and utilization rate of the rotatable rack.
