In particular, the thickness of the insulation layer should meet the design requirements, and the insulation method shall not be changed without authorization; when bonding the insulation materials, the sundries, dust, and oil stains on the pipeline surface must be cleaned up to ensure the bonding effect of the glue.

One side of the insulation layer is opened and sleeved on the end of the pipeline and then inserted. Immediately, the two-way insulation layer interfaces are butted to complete the fitting. The other is for the installed pipeline. The insulation layer is semi-circular. After the side ports are sleeved and fitted in sequence, the interface fitting is completed. For the first installation method mentioned above, in the actual installation of large pipelines, there is a large friction between the pipeline and the insulation layer, and the circumferential force on the insulation layer is uneven during the dragging process, which leads to the curling phenomenon during the advancement of the insulation layer, making the insulation layer unable to be installed smoothly.

[0004] In view of the above technical defects, a solution is proposed now. Summary of the Utility Model

[0008] Preferably, a guiding insertion block matching the guiding groove is connected to the inner side of the outer pressing plate, the guiding insertion block is connected to the screw ring, and a plurality of dial rods are installed at the upper end of the adjusting screw rod.

[0009] Preferably, the guiding insertion block is of a "T" shape and matches the guiding groove, and when the adjusting screw rod rotates, the outer pressing plate is driven by the screw ring to move radially along the docking half-ring.

[0026] Please refer to Figure 1 - Figure 7As shown in the figure, this embodiment is an interface connection device for installing a pipeline insulation layer, including a support base 1, a pipeline 3 and an insulation layer 4 arranged on the support base 1. Propulsion wheels 8 for supporting the pipeline 3 are installed at both ends of the support base 1. A pair of slide rails 12 are installed on the upper parts of the inner sides of both ends of the support base 1. A docking mechanism for docking the insulation layer 4 is slidably installed on the pair of slide rails 12. The docking mechanism includes a pair of symmetrically arranged docking half-rings 5. Inner pressing plates 11 are installed at the inner ends of the inner ring sides of the docking half-rings 5. Outer pressing plates 6 concentric with the inner pressing plates 11 are radially movably installed at the inner ends of the outer ring sides of the docking half-rings 5. An adjusting assembly connected to the outer pressing plates 6 is arranged on the docking half-rings 5. A support ring 10 that fits the inner bottom of the pipeline 3 is installed in the middle of the inner bottom end of the support base 1;

[0027] The adjusting assembly includes a guiding groove 19 and an adjusting screw 13 opened on the docking half-ring 5. An installation hole 20 communicating with the guiding groove 19 is opened on the docking half-ring 5. The adjusting screw 13 is rotatably installed at the inner bottom of the installation hole 20.

When the adjusting screw 13 rotates, the outer pressing plate 6 is driven by the screw ring 18 to move radially along the docking half-ring 5;

[0028] When the rotatably arranged adjusting screw 13 rotates, it drives the screw ring 18 to move radially, thereby changing the radial distance between the concentrically arranged outer pressing plate 6 and inner pressing plate 11, and further completing the stable clamping of the end of the flexible insulation layer.

The specific docking steps are as follows: Press the inner pressing plate 11 against the inner ring side of the insulation layer 4, and the docking half-ring 5 contacts the end of the insulation layer 4. Then, adjust the adjusting screw 13 through the dial rod 21. When the adjusting screw 13 rotates, it drives the screw ring 18 to move. Then, the guiding insertion block 17 vertically moves in the guiding groove 19 and drives the outer pressing plate 6 to approach the inner pressing plate 11 to complete the clamping of the upper side of the end of the insulation layer 4. Subsequently, synchronously clamp the lower side of the end of the insulation layer 4 by the outer pressing plate 6 and the inner pressing plate 11 on the lower docking half-ring 5. After double clamping, pull the docking half-ring 5 to drive the insulation layer 4 to move smoothly outside the pipeline 3, thereby completing the smooth laying of the insulation layer 4;

[0030] Refer toFigure 6 As shown in the figure, during the laying process, after completing the laying of a section of the thermal insulation layer 4, the laying of another adjacent section of the thermal insulation layer 4 is carried out according to the above steps, and a certain distance is compensatorily pulled inward at the end of the previous section of the thermal insulation layer 4, so as to ensure that the two sections of the thermal insulation layer 4 after docking can achieve end alignment, complete the compensation for the space occupied by the two docking mechanisms, and then apply glue for bonding;

[0031] The beneficial effects are as follows: The symmetrically arranged docking mechanisms can effectively realize the multi-section connection of the pipeline thermal insulation layer, and apply a uniform pulling force during the connection process to ensure stable laying of the pipeline thermal insulation layer during the process of moving and sleeving outside the pipeline, avoiding the phenomenon of end curling or even inability to continue advancing caused by uneven stress during the dragging of the thermal insulation layer, and enabling stable mating between the ends of the thermal insulation layer.

Then, adjust the adjusting screw 13 through the lever 21 to drive the outer pressure plate 6 to approach the inner pressure plate 11 to complete the clamping of the upper side of the end of the insulation layer 4. Synchronously, the outer pressure plate 6 and the inner pressure plate 11 on the lower docking half-ring 5 clamp the lower side of the end of the insulation layer 4. After double clamping, pull the docking half-ring 5 to drive the insulation layer 4 to move smoothly outside the pipeline 3.
