Description

Technical Field

[0001] This utility model relates to the technical field of thermal insulation pipe production and processing equipment, and more specifically, to a cooling device for the production of prefabricated direct-buried thermal insulation pipes. Background Technology

[0002] Pre-insulated direct-buried pipes are tightly bonded together with a steel pipe (working pipe) for transporting the medium, rigid polyurethane foam (insulation layer), and a high-density polyethylene outer casing (protective layer). Cooling treatment is required during the production process of pre-insulated direct-buried pipes.

[0003] A search revealed a cooling device for the production of prefabricated direct-buried insulated pipes, with publication number CN221898085U. This device includes a cooling water tank filled with cooling water to cool the insulated pipe body. A pipe-supporting mechanism is symmetrically arranged inside the cooling water tank. This mechanism includes an expansion component and an adjustment component. The pipe-supporting mechanism is used to fix the insulated pipe body, while the expansion component drives the expansion plate to expand and contract to fix the insulated pipe body. Through the expansion component and adjustment component, after the insulated pipe body is placed, it can be expanded and fixed for insulated pipe bodies of different diameters, preventing the insulated pipe body from shifting and floating in the water, achieving a better cooling effect, and making it easy to remove.

[0004] When water-cooling insulated pipes, residual water easily adheres to the surface of the pipe after cooling. If it cannot be dried in time, it will affect the subsequent pipe processing and reduce work efficiency. Therefore, we have proposed a cooling device for the production of prefabricated direct-buried insulated pipes to solve the above problems. Utility Model Content

[0005] 1. Technical problems to be solved

[0006] To address the problems existing in the prior art, the purpose of this utility model is to provide a cooling device for the production of prefabricated direct-buried insulated pipes. The cooling tank contains a storage assembly, with the bottom plate lower than the coolant level. The insulated pipe is placed on the bracket surface of the bottom plate, and the top plate is pressed down relative to the bottom plate. The damping rod slides relative to the sleeve until the pressure strip on the top plate surface presses against the upper surface of the insulated pipe. Pressure continues to be applied to the top plate, causing the guide ring to slide down along the guide column, immersing the insulated pipe below the coolant level, resulting in excellent cooling. The top plate is lifted longitudinally, and with the assistance of the guide column, the bottom plate drives the insulated pipe to rise longitudinally. The operation is convenient, and the small contact area between the bracket and pressure strip and the insulated pipe facilitates coolant dripping and reduces residue.

[0007] 2. Technical Solution

[0008] To solve the above problems, the present invention adopts the following technical solution.

[0009] A cooling device for the production of prefabricated direct-buried insulated pipes includes a cooling box, wherein guide columns are symmetrically installed inside the cooling box, and a storage component is inserted into the cooling box.

[0010] The storage assembly includes a guide ring that is sleeved on the outside of the guide post and is slidably disposed, a connecting rod welded to the surface of the guide ring, a base plate fixedly connected to the end of the connecting rod, and brackets welded equidistantly to the surface of the base plate.

[0011] The storage assembly also includes sleeves symmetrically mounted on the surface of the base plate. A damping rod is slidably inserted into the inside of each sleeve. A top plate is fixedly connected to the top of the damping rod, and pressure strips are equidistantly mounted on the surface of the top plate. The storage assembly is inserted inside the cooling tank. The base plate is lower than the coolant level in the cooling tank. The insulation tube is placed on the bracket surface of the base plate, and the top plate is pressed down relative to the base plate. The damping rod slides relative to the sleeve until the pressure strips on the top plate surface press against the upper surface of the insulation tube. Continued pressure is applied to the top plate, causing the guide ring to slide down along the guide post, immersing the insulation tube below the coolant level, resulting in excellent cooling. The top plate is lifted longitudinally; with the assistance of the guide post, the base plate drives the insulation tube to rise longitudinally. The operation is convenient, and the small contact area between the brackets and pressure strips and the insulation tube facilitates coolant dripping and reduces residue.

[0012] Preferably, a limiting seat is fixedly connected to the top end of the guide post, and a limiting ring is sleeved on the outside of the guide post.

[0013] Preferably, the guide ring is located between the limiting seat and the limiting ring.

The insulation tube is placed on the bracket surface of the bottom plate and the top plate is pressed down relative to the bottom plate. The damping rod slides relative to the sleeve until the pressure strip on the surface of the top plate is pressed against the upper surface of the insulation tube. Continue to apply pressure to the top plate, and the guide ring slides down along the guide column. The insulation tube is immersed in the lower position of the coolant, which has a good cooling effect. The top plate is lifted longitudinally. With the assistance of the guide column, the bottom plate drives the insulation tube to be lifted longitudinally. The operation process is convenient. The contact area between the bracket and the pressure strip and the insulation tube is small, which facilitates the dripping of coolant and reduces residue.

[0021] (2) The surface of the cooling box of this solution is symmetrically equipped with cleaning components. The air blowing hood and the air guide seat are connected. The air pipe connector is connected to the external blower through the external pipe. During the process of longitudinally raising the insulation pipe relative to the cooling box, the blower is started. The pressurized air blows along the air blowing hood to the surface of the insulation pipe, accelerating the dripping of residual liquid, thereby effectively shortening the natural drying cycle and improving work efficiency.
