Description

Technical Field

[0001] The present invention relates to the technical field of electric heating tapes, and in particular to a high-temperature resistant insulating AHT armored electric heating tape. Background Art

[0002] An electric heating tape is a strip-shaped heating and insulation device that generates heat by driving an internal heating element with electric energy and is wrapped around the surface of a pipe or equipment to maintain or increase its temperature. The principle is to use a heating core wire or resistance wire to generate heat evenly to compensate for the heat loss of the pipe. The invention patent with Chinese patent publication number CN113840407B discloses a high-temperature resistant insulated AHT armored electric heating tape, including an electric heating tape body, which includes a first metal wire and a second metal wire. A conductive plastic layer is provided on the outside of the first metal wire and the second metal wire. The conductive plastic layer is made of PCT plastic and isolates the first metal wire and the second metal wire. An insulating layer is provided on the outside of the conductive plastic layer. It has the advantages of good high-temperature resistance and energy saving.

[0003] In the above-mentioned prior art, a mesh metal wire layer and a sheath layer are arranged outside the surface insulation layer of the electric heating cable, and the insulation layer and the protective cover are made of modified polyolefin material, which has the advantage of good high temperature resistance. However, when laying this type of high-temperature resistant insulation type AHT armored electric heating cable, there are usually two ways: straight fitting pipeline and spiral uniform winding. Due to the complexity of the installation environment of equipment such as pipelines, manual laying is often required. As a result, in long-distance laying such as municipal engineering, it is limited by the experience of the operator, resulting in excessive bending during straight laying and uneven spiral spacing during spiral installation, resulting in local overheating or local low temperature, which is not conducive to the safe use of the electric heating cable. Summary of the Invention

[0004] The object of the present invention is to provide a high temperature resistant insulated AHT armored electric heating tape to solve the problems raised in the above background technology.

[0005] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: a high-temperature resistant insulating AHT armored electric heating tape, comprising an electric heating tape, a T-shaped stage movably mounted on the electric heating tape, a slot being provided on the T-shaped stage, the electric heating tape movably mounted in the slot, a wall-adhering mechanism for fitting pipes of different diameters mounted on the T-shaped stage, a rotating mechanism for constraining the laying path of the electric heating tape on the pipe mounted on the wall-adhering mechanism, an adjusting mechanism for adjusting and locking the rotating mechanism mounted on the wall-adhering mechanism, a pressure rod mechanism for assisting in tightening the adhesive joint between the electric heating tape and the pipe mounted on the T-shaped stage, a dust cleaning mechanism for cleaning the surface of the pipe to be laid when laying the electric heating tape, a clamping mechanism for fixing the wall-adhering mechanism when gluing the pipe and the electric heating tape mounted on the T-shaped stage, when the electric heating tape is being laid, one end of the electric heating tape is sleeved on the T-shaped stage, the size of the wall-adhering mechanism is adjusted so that the electric heating tape fits on the pipe, and the laying is completed. After the point is fixed, the rotating mechanism is adjusted according to the laying path and then the fixing of the rotating mechanism is completed through the adjustment mechanism. At this time, the T-type stage can be moved to make it possible to lay in a straight line or in a uniform spiral shape. During this process, the sliding of the T-type stage drives the cleaning mechanism to clean the surface of the pipe where the electric heating tape is not laid. After sliding for a certain distance, the clamping mechanism is driven to move by pressing the pressure rod mechanism to clamp the electric heating tape to prevent the T-type stage from continuing to slide. When the pressure rod mechanism moves, it drives the cleaning mechanism to self-clean and scrapes off the dust attached to the cleaning mechanism components when cleaning the pipe, making it convenient for the cleaning mechanism to clean the pipe during continuous laying. When the pressure rod mechanism contacts the electric heating tape, the electric heating tape is tightly fitted to the pipe. At this time, it can be fixed with aluminum foil tape. According to the above principle, the electric heating tape is laid through the guide track during the continuous laying process to prevent overheating and local low temperature caused by excessive bending or overlapping of the electric heating tape.

[0006] Furthermore, the wall-adhering mechanism includes a limiting screw, which is rotatably installed on the T-stage, and an arc end block is threadedly installed on the limiting screw, and the arc end block is slidably installed on the T-stage. A twisting block is installed on the limiting screw, and the twisting block contacts the T-stage. A threaded hole is provided on the arc end block, and the limiting screw is threaded in the threaded hole. Rotating the twisting block drives the limiting screw to rotate on the T-stage, and the rotation of the limiting screw drives the arc end blocks on both sides to slide closer or away from each other, thereby adapting to pipes of different diameters, so that the arc end block always fits the outer wall of the pipe. It should be noted that the threaded holes on the limiting screws on both sides are in opposite directions.

[0007] Furthermore, the rotating mechanism includes a rotating block, which is rotatably mounted on the arc end block, a rotating shaft being mounted on the rotating block, a ball block being rotatably mounted on the rotating shaft, a spherical groove being provided on the rotating block, and the ball block being rotatably mounted in the spherical groove. When the T-type stage slides, the ball block in contact with the pipe rotates on the rotating shaft to guide the sliding of the T-type stage. It should be noted that by adjusting the contact force between the arc end block and the pipe, relative sliding between the ball block and the pipe can be prevented when the T-type stage slides.

[0008] Furthermore, the adjustment mechanism includes a gear block, which is installed on the rotating block. An arc-shaped slide is slidably installed on the arc end block. The arc-shaped slide is provided with continuous tooth grooves, which engage with the gear block. The arc-shaped slide is slid on the arc end block.

[0009] Furthermore, a pin hole is provided on the arc-shaped slide plate, a limit slide bar is slidably installed on the arc end block, a pin block is installed on the limit slide bar, the pin block is adapted to the pin hole, a spring is movably sleeved on the limit slide bar, and the spring is installed on the arc end block. After pulling the pin block out of the pin hole, the arc-shaped slide plate can be slid on the arc end block. After sliding to the target position, the pin block is released, and the pin block is driven to fall back into the pin hole under the action of the restoring elastic force of the spring to complete the fixation of the structure.

[0010] Furthermore, the pressure rod mechanism includes a base, which is installed on a T-shaped stage, a rotating rod is installed on the base, a rotating sleeve is rotatably installed on the rotating rod, a pressure plate is installed on the rotating sleeve, an arc end pressure block is installed on the pressure plate, a torsion spring is installed on the rotating sleeve, and the torsion spring is installed on the rotating rod. When the electric heating tape and the pipeline are fixed by aluminum foil tape, the pressure plate is pressed to make the pressure plate rotate on the base through the rotating sleeve, thereby driving the arc end pressure block to contact the electric heating tape and making the electric heating tape and the pipeline fit tightly, which is beneficial to the fixing process of the aluminum foil tape. After the fixing is completed, the pressure plate is released, and the structure is reset under the action of the reset elastic force of the torsion spring. According to the above principle, the continuous installation process of the electric heating tape can be completed.

[0011] Furthermore, the cleaning mechanism includes a tooth plate, which is slidably mounted on the T-stage, a missing gear is mounted on the rotating sleeve, the missing gear is meshed with the tooth plate, a connecting plate is mounted on the tooth plate, a straight plate is plugged into the bottom side of the connecting plate, a limiting slide is mounted on the straight plate, the limiting slide is slidably mounted on the T-stage, an arc-shaped scraper is mounted on the straight plate, a slot is provided on the arc-shaped scraper, a scraping brush is mounted on the arc end block, the scraping brush is movably sleeved in the slot on the arc-shaped scraper, when the T-stage slides, the scraping brush on the arc end block slides synchronously to clean the outer wall of the pipeline to be laid with the electric heating tape, and when the pressure plate is pressed, the missing gear on the rotating sleeve drives the tooth plate to slide on the T-stage, thereby driving the straight plate and the arc-shaped scraper on the straight plate through the connecting plate to clean the dust attached to the scraping brush, which facilitates the use of the scraping brush during the continuous laying of the electric heating tape, and further improves the convenience and practicality of the structure.

[0012] Furthermore, the clamping mechanism includes a connecting shaft, which is slidably mounted on the T-stage, a friction block is mounted on the connecting shaft, a C-plate is slidably mounted on the connecting shaft, a rotating plate is mounted on the C-plate, a swivel seat is mounted on the pressure plate, the rotating plate is rotatably mounted on the swivel seat, a guide slot is provided on the C-plate, the upper part of the guide slot is a straight slot, and the lower part of the guide slot is an inclined slot, the connecting shaft is slidably mounted in the guide slot, and when the pressure plate is pressed, the rotating plate rotates on the swivel seat and drives the C-plate to slide on the T-stage at the same time, and the C-plate slides through the guide slot to drive the connecting shafts on both sides to slide close to each other on the T-stage, thereby driving the friction blocks to approach each other and contact the electric heating tape, thereby preventing the T-stage from sliding during the pressing process through the static friction between the friction block and the electric heating tape, further improving the convenience and practicality of the structure.

[0013] Furthermore, a limiting sliding groove is provided on the T-shaped stage, and the connecting shaft is slidably installed in the limiting sliding groove. The limiting sliding groove limits the movement of the connecting shaft, and the connecting shaft can and can only slide in the limiting sliding groove.

[0014] Furthermore, a T-shaped groove is provided on the T-shaped stage, and a T-shaped slider is installed on the C-shaped plate. The T-shaped slider is slidably installed in the T-shaped groove.

[0016] The present invention, through the arrangement of arc end blocks, ball blocks, rotating shafts, gear blocks, friction blocks, arc-shaped slides, etc., can achieve the following during long-distance laying of electric semi-heating tape: after the size of the arc end blocks is adjusted so that the ball blocks fit against the outer wall of the pipeline, the sliding of the arc-shaped slides can drive the change of the rotation direction of the ball blocks, thereby achieving path guidance during straight-line laying and spiral laying, preventing the occurrence of local temperature anomalies caused by excessive bending and uneven spiral pitch, and improving the safety and convenience of the electric heating tape.

[0017] The present invention, through the arrangement of arc-shaped scrapers, scraping brushes, etc., realizes that when the T-shaped stage is slid, the scraping brush on the arc end block slides synchronously to clean the outer wall of the pipe where the electric heating tape is to be laid, and when the pressure plate is pressed, the missing gear on the rotating sleeve drives the toothed plate to slide on the T-shaped stage, thereby driving the straight plate and the arc-shaped scraper on the straight plate through the connecting plate to clean the dust attached to the scraping brush, which facilitates the use of the scraping brush during the continuous laying of the electric heating tape, and further improves the convenience and practicality of the structure.

[0018] The present invention realizes that when the pressing plate is pressed, the rotating plate rotates on the rotating seat and drives the C-shaped plate to slide on the T-shaped stage at the same time, and the sliding of the C-shaped plate drives the connecting shafts on both sides to slide close to each other on the T-shaped stage through the guide groove, thereby driving the friction blocks to approach each other and contact the electric heating tape, so that the static friction between the friction block and the electric heating tape prevents the T-shaped stage from sliding during the pressing process, further improving the convenience and practicality of the structure.
