A direct buried spray winding insulation pipe patching device

Abstract

The utility model discloses a direct-buried spray-wrapped thermal insulation pipe patching device, comprising a support frame, which is used for supporting and positioning the direct-buried spray-wrapped thermal insulation pipe patching device. A winding adjustment mechanism is fixedly arranged in the middle position of the support frame, and a patching winding mechanism is fixedly arranged at the top of the winding adjustment mechanism. The utility model meshes the tooth surface of the positioning gear with the positioning tooth groove opened on the outer wall of the positioning ring, so that the positioning ring slides along the inner wall of the positioning groove. Since the sizes of the positioning frame and the positioning ring correspond and the lengths are both greater than the semicircle, the other end of the positioning ring is slidably connected to the other end of the positioning groove, so that the positioning ring always slides around the outer wall of the positioning groove, so that the positioning ring drives the mounting frame and the fixing frame fixed on one side to rotate, and the hot-melt tape roll is wound along the outer wall of the direct-buried spray-wrapped thermal insulation pipe, thereby increasing the winding efficiency of the hot-melt tape roll and improving the winding stability of the hot-melt tape roll.

Description

Technical Field

[0001] The utility model relates to the technical field of direct-buried spray-wound thermal insulation pipes, in particular to a direct-buried spray-wound thermal insulation pipe patching device. Background Art

[0002] Spray-wrap insulation pipe is a commonly used pipe insulation method. It mainly uses special equipment to wrap glass fiber felt or rock wool felt around pipes or equipment, and applies adhesive to the felt through a spraying process to form a dense, flat and uniform insulation layer. The insulation pipe has a reserved position at the end to facilitate welding operations at the pipe joint. After welding, the reserved position needs to be patched. First, the polyurethane foam layer is sprayed, and then the hot melt tape is used for wrapping. After wrapping, the hot melt tape is melted with a high-temperature spray gun to make it fit tightly with the polyurethane foam layer to achieve sealing and protection.

[0003] In view of this, Chinese patent No. CN216506721 U proposes a direct-buried spray-wrapped insulated pipe patching device, which realizes automatic patching of the insulated pipe joint by providing a supporting roller for supporting a hot-melt tape roll and pressing and winding the hot-melt tape of the hot-melt tape roll onto the polyurethane layer at the joint position of the spray-wrapped insulated pipe, thereby eliminating manual labor, improving construction efficiency, and ensuring high hot-melt tape winding uniformity. In the above patent, the direct-buried spray-wrapped insulated pipe patching device usually rotates the direct-buried spray-wrapped insulated pipe during winding. Since the direct-buried spray-wrapped insulated pipe is heavy and rotates slowly, the efficiency of winding the pipe mouth of the direct-buried spray-wrapped insulated pipe is low, and the slow rotation makes it difficult to adjust the tightness of the hot-melt tape roll, reducing the convenience of using the direct-buried spray-wrapped insulated pipe patching device. Therefore, a direct-buried spray-wrapped insulated pipe patching device is needed. Utility Model Content

[0015] 1. A directly buried spray-wrapped thermal insulation pipe patching device meshes the tooth surface of the positioning gear with the positioning tooth groove opened on the outer wall of the positioning ring, so that the positioning ring slides along the inner wall of the positioning groove.

Moreover, through the adjustment of the electric telescopic rod, the direct-buried spray-wrapped thermal insulation pipe patching device is convenient for patching direct-buried spray-wrapped thermal insulation pipes of different sizes, thereby increasing the practicality of the direct-buried spray-wrapped thermal insulation pipe patching device.
