Description

Technical Field

[0001] The utility model relates to the technical field of heat pipelines, in particular to a heat pipeline protection device. Background Art

[0002] Heat pipelines start from boiler rooms, direct-fired engine rooms, heat supply centers, etc., and are heat supply pipelines leading from the heat source to the heat inlet of buildings. When laying heat pipelines, support and protection devices are used to provide support and protection for the connection parts of the heat pipelines. However, the existing support and protection devices use annular clamps to wrap the heat pipelines. Affected by the temperature of the fluid inside the pipeline, the heat pipelines will expand and contract thermally. When the pipeline expands and contracts thermally, changes in length and diameter will occur. The annular clamp will hold the pipeline tightly and does not allow the pipeline to expand and contract freely, which will cause the pipeline to be subjected to uneven stress. This uneven stress may generate cracks at the vulnerable points or joints of the pipeline, ultimately leading to the tearing or rupture of the pipeline.

[0003] For example, a heat pipeline connection protection device disclosed in the patent with the publication number CN213299030U includes a support plate with a hollow structure. The center position of the top surface of the support plate is fixedly connected with a hollow tube. A slider is slidably connected inside the hollow tube. The inner side of the support plate is rotatably connected with a first belt pulley through a rotating shaft. The first belt pulley is located on the axis of the slider. The center position of the top surface of the first belt pulley is fixedly connected with a threaded shaft through a connecting shaft; The staff closes the second grooved hoop and uses bolts to fasten the first grooved hoop and the second grooved hoop. At this time, the first grooved hoop and the second grooved hoop wrap the flange connection of the heat pipeline inside, and the first grooved hoop and the second grooved hoop are tightly connected to the flange and the pipeline of the heat pipeline. Then, the extended parts of the first grooved hoop and the second grooved hoop provide a certain support for the parts on both sides of the pipeline flange. Although this patent can provide support for the parts on both sides of the pipeline flange, the clamps on it will fasten the pipeline. When the heat pipeline expands and contracts thermally, it is easy to cause the heat pipeline to be subjected to uneven stress and easy to cause the connection of the heat pipeline to rupture.

Detailed Embodiment

[0017] Embodiment 1

[0018] As Figures 1 to 3As shown in the figure, the utility model discloses a thermal pipeline protection device. The adopted technical solution is as follows: it includes a bottom plate 1 and a first fixing plate 2. The first fixing plate 2 is arc-shaped. The top of one end of the first fixing plate 2 is hinged to a second fixing plate 3. Fixing holes 8 that cooperate with each other are provided on the side surfaces of one ends of the first fixing plate 2 and the second fixing plate 3. Through the fixing holes 8, one end of the second fixing plate 3 can be fixed to the first fixing plate 2 by bolts. Semi-circular positioning grooves 10 are provided on the side surfaces of one ends of the first fixing plate 2 and the second fixing plate 3. The two positioning grooves 10 cooperate with a U-shaped positioning pin 11. Through the cooperation of the positioning pin 11 and the positioning grooves 10, the second fixing plate 3 can be positioned when the second fixing plate 3 rotates to the first fixing plate 2, facilitating people to fix the second fixing plate 3 with bolts. Movable fixing mechanisms 5 are installed on both the first fixing plate 2 and the second fixing plate 3. Two lateral offset mechanisms 4 are installed on the bottom plate 1. Mounting holes 9 are provided at the four corners of the top of the bottom plate 1. Through the mounting holes 9, the bottom plate 1 can be fixed at the using position, improving the stability of the bottom plate 1;

[0019] The lateral offset mechanism 4 includes a support plate 41, a first spring 42, a chute 43 and a moving plate 44. There are two support plates 41, and the two support plates 41 are fixedly installed on both sides of the top of the bottom plate 1. The chute 43 is opened in the middle of the top of the bottom plate 1. The lower end of the moving plate 44 is slidably installed in the chute 43. There are two first springs 42, and the two ends of the two first springs 42 are respectively fixedly connected to the side surfaces of the two support plates 41 and the two side surfaces of the moving plate 44. The two first springs 42 are respectively located on both sides of the moving plate 44. The top of the moving plate 44 is fixedly connected to the side surface of the first fixing plate 2. Through the moving plate 44 and the first spring 42, when the thermal pipeline expands and contracts thermally, the first fixing plate 2 and the second fixing plate 3 can move following the expansion and contraction of the pipeline, enabling the entire thermal pipeline to receive uniform stress and avoiding pipeline rupture;

[0020] The movable fixing mechanism 5 includes a clamping plate 51, guide rods 52, a spring 53, an adjusting plate 54, and a screw rod 55. There are two guide rods 52. One end of each of the two guide rods 52 is fixedly connected to the side surface of the clamping plate 51. The clamping plate 51 is arc-shaped, and a rubber pad 7 is fixedly installed on the arc surface of the clamping plate 51. The rubber pad 7 can provide protection for the heat pipeline, preventing the clamping plate 51 from damaging the insulation layer of the heat pipeline. The other ends of the two guide rods 52 respectively pass through two sliding holes on the arc surface of the first fixing plate 2. One end of the screw rod 55 is rotatably connected to the middle of the end surface of the adjusting plate 54. The other end of the screw rod 55 passes through the screw hole on the arc surface of the first fixing plate 2. The end surface of the other end of the screw rod 55 is fixedly connected to the middle of the end surface of the driving block 6. The cross-section of the driving block 6 is a regular hexagon, enabling people to conveniently twist the screw rod 55 to rotate for adjusting the elasticity of the spring 53. The two ends of the spring 53 are respectively fixedly connected to the side surface of the clamping plate 51 and the other end surface of the adjusting plate 54. By connecting the first fixing plate 2 and the second fixing plate 3, the clamping plates 51 on the first fixing plate 2 and the second fixing plate 3 can be brought into contact with the heat pipeline, providing support and a certain degree of fastening for the heat pipeline. When the heat pipeline expands and contracts thermally, the stress of the heat pipeline will push the clamping plate 51 to move, enabling the diameter of the heat pipeline to change simultaneously at the support part during thermal expansion and contraction, preventing the heat pipeline from being subjected to uneven stress, and thus avoiding cracks at the connection of the heat pipeline.

[0021] The working principle of the present utility model: Fix the bottom plate 1 directly below the pipeline connection part through the mounting hole 9, so that the clamping plate 51 on the first fixing plate 2 is in contact with the heat pipeline. Rotate the second fixing plate 3 to cover the heat pipeline, making the clamping plate 51 on the second fixing plate 3 in contact with the heat pipeline. Insert the positioning pin 11 into the positioning groove 10 on the first fixing plate 2 and the second fixing plate 3, and insert bolts into the fixing holes 8 to fix one end of the first fixing plate 2 and the second fixing plate 3 together. Twist the driving block 6 to drive the screw rod 55 to rotate, causing the screw rod 55 to drive the adjusting plate 54 to move towards the middle along the threads of the screw holes on the first fixing plate 2 and the second fixing plate 3, compressing the spring 53 by the adjusting plate 54, and using the elasticity of the spring 53 and the clamping plate 51 to relatively fix the heat pipeline. When the temperature of the fluid in the heat pipeline changes and the pipeline expands and contracts thermally, the expansion force of the pipeline will push the clamping plate 51 to move, enabling the clamping plate 51 to relatively fix the pipeline while being movable, without affecting the expansion and contraction of the pipeline. At the same time, when the pipeline expands and contracts thermally, the pipeline will pull the clamping plate 51, the first fixing plate 2, and the second fixing plate 3, causing the first fixing plate 2 to drive the moving plate 44 to move, stretching and compressing the first spring 42 by the moving plate 44. Thus, when the heat pipeline expands and contracts thermally, the entire protection device can move relatively following the expansion and contraction of the pipeline, enabling the connection part of the heat pipeline to be supported and protected while not being affected by the thermal expansion and contraction stress, thereby avoiding damage to the pipeline.
