Description

Technical Field

[0001] The invention relates to the technical field of laying a thermal insulation layer of a steam pipe network, and in particular to a device for laying a thermal insulation layer of a heating steam pipe network. Background Art

[0002] As we all know, during the transmission of steam in the pipeline network, if there is no insulation layer, a large amount of heat will be lost to the surrounding environment through the pipe wall, resulting in a decrease in the temperature and pressure of the steam, affecting the quality and use of the steam. Laying an insulation layer can significantly reduce heat loss, improve energy utilization efficiency, reduce energy consumption and operating costs, and by maintaining the temperature and pressure of the steam and reducing steam condensation and pressure drop caused by heat loss, the steam can be delivered to the user end more quickly and efficiently, thereby improving the transmission efficiency of the entire steam pipeline system. The insulation layer can also reduce the temperature of the pipeline surface to avoid scalding accidents when workers touch the pipeline. In addition, the insulation layer can play a certain protective role on the pipeline, reduce the erosion and damage of the pipeline by the external environment, such as moisture and corrosive gases in the atmosphere, and extend the service life of the pipeline.

[0003] It can be used when laying the insulation layer of the steam pipe network. The problem with the existing technology is that the cut insulation material needs to be wound and laid during the laying process, but most of them are completed using glue coating equipment and bundling equipment respectively. Not only is the efficiency low, but it also requires human assistance during the winding process. Therefore, it is difficult for a single person to carry out continuous work, especially in the operation position of a longer pipeline, where it is often necessary to cut the material and perform multiple gluing operations, which is inconvenient to use.

[0004] Based on the above-mentioned situations, we found that it is difficult to avoid the above problems in the process of laying the insulation layer of the steam pipe network in the existing technology. Therefore, we proposed a steam pipe network insulation layer laying device that has the integrated features of uniform speed laying and gluing, and can be laid by a single person with little effort. Summary of the invention

[0005] 1. Technical issues to be resolved

[0006] In view of the deficiencies in the prior art, the present invention provides a device for laying a thermal insulation layer of a heating steam pipe network, which has the advantages of integrating uniform-speed laying and gluing, and can be laid by a single person with little effort.

[0007] (II) Technical solution

[0008] The above technical objectives of the present invention are achieved through the following technical solutions: a device for laying the thermal insulation layer of a heating steam pipe network, comprising a main frame and a sub-frame, wherein the inner side of the top of the main frame is rotatably connected to a main rod, the outer side of the main rod is rotatably connected to the inner side of the top of the sub-frame, the front side of the main frame is bolted to a ring frame, the rear side of the ring frame is movably connected to a matching ring, the outer side of the main frame is slidably connected to a slide frame, the right side of the slide frame is movably connected to a side frame, a glue coating tank is installed at the bottom of the side frame, and a reduction motor is bolted to the top of the slide frame. The output shaft of the reduction motor passes through the slide to the inner side of the slide and is bolted with a gear. The inner sides of the ring frame and the matching ring are both bolted with tooth blocks. The tooth blocks are meshingly connected with the gears. The right side of the side frame is movably connected with a fixed frame. A roller frame is installed at the bottom of the fixed frame. A pressure roller is rotatably connected to the inner side of the roller frame. An angle plate is bolted to the rear side of the roller frame. A rectangular frame is bolted to the rear side of the angle plate. Two limiting rollers are installed on the inner side of the rectangular frame. A driving bracket is bolted to the left side of the main frame. A driving wheel is provided on the inner side of the driving bracket.

[0009] The glue coating tank comprises a container shell, the inner side of the container shell is provided with a hollow bracket, the inner wall of the hollow bracket is bolted with a return spring, the inner side of the hollow bracket is provided with a ball, and the outer side of the ball is in contact with the return spring.

[0010] The above technical scheme is adopted, by setting a main frame and a sub-frame, it is convenient to connect them through the main rod so that they can rotate with each other, and the rollers on the inside of the main frame and the sub-frame can be easily stuck on the surface of the laid pipeline and can support it, and can avoid excessive sliding friction when the structure moves along the pipeline. The set ring frame and matching ring can first clamp the structure on the outside of the pipeline through the main frame and the sub-frame when in use, and then slide the slide to the outside of the ring frame, and install the matching ring and the ring frame, and pass the insulation material cut into strips from the front through the bottom of the pressure roller and between the two limiting rollers respectively, and then fix them on the surface of the pipeline. When the reduction motor is started, it is convenient to drive the slide to perform circular motion along the matching ring and the ring frame through the meshing of the gear and the tooth block, and the glue coating tank connected to it through the side frame can perform glue coating on the surface of the pipeline passed by, and the pressure roller on the inner side of the roller frame at the bottom of the fixed frame can The heat-insulating material at the bottom is pressed together, and the heat-insulating material is spirally wound and laid on the surface of the pipeline under the limit of the limit roller, and the rapid laying action is completed by contacting the glue coated by the glue coating tank. The set driving bracket cooperates with the driving wheel to provide a certain power and speed limit, so only one person is needed to assist in contacting the main rod and other positions to carry out the operation, which reduces the number of people and manpower required for the operation, and improves the operation efficiency and laying uniformity. When the glue coating operation is carried out, the glue can be filled on the inside of the container shell first, and when the ball contacts the surface of the pipe body, the return spring is pressed to create a gap between the ball and the return spring for the glue to flow out, and when the ball rolls, the glue attached to its surface adheres to the surface of the pipe body to complete uniform spiral pipeline laying. When the structure does not contact the pipeline, the return spring presses the ball against the inside of the container shell to avoid the glue flowing out, which makes it difficult to clean or wastes the glue.

[0011] The present invention is further configured as follows: a connecting torsion spring is sleeved on the outer side of the main rod, and the connecting torsion spring is bolted to the main frame and the sub-frame at one side thereof close to the main frame and the sub-frame respectively.

The limit rod can facilitate the displacement between the structures to avoid unusability due to rotation or tilting.

[0017] The present invention is further configured as follows: a fastening screw is threadedly connected to the inner side of the side frame, and the outer side of the fastening screw is sleeved with the fixing frame.

[0018] By adopting the above technical solution and setting a screw rod, when it is necessary to adjust the angle between the fixed frame and the side frame, the screw rod can be loosened to the desired position and then tightened to fix it.

[0019] The present invention is further configured as follows: the outer side of the bottom limiting roller is rotatably connected to the rectangular frame, the outer side of the top limiting roller is rotatably connected to an adjustment plate, the top of the rectangular frame is threadedly connected to a transmission screw, and the bottom of the transmission screw is rotatably connected to the adjustment plate.

[0020] By adopting the above technical solution, by setting an adjustment plate in conjunction with a transmission screw, the spacing between the top limiting roller and the bottom limiting roller can be easily adjusted to facilitate the passage of the insulation material or to adjust according to the thickness of the insulation material.
