Description

Technical Field

[0001] This invention relates to the field of electrical engineering and its automation pipeline connection technology, and in particular to a pipeline connection support and protection device. Background Technology

[0002] Electrical engineering requires pipeline laying. Currently, steam pipelines used in power plants need to be installed and connected in an elevated manner. To account for pipeline displacement caused by thermal expansion and contraction, expansion joints are usually installed in steam pipelines. Therefore, the current devices for connecting and protecting steam pipelines can only provide support and cannot provide stable limiting, resulting in low safety. Summary of the Invention

[0003] The purpose of this invention is to provide a pipeline connection support and protection device that can not only clamp and support the pipeline, but also automatically adjust its position according to the thermal expansion and contraction of the pipeline.

[0004] This invention provides a pipeline connection support and protection device, including a support base, a connecting plate slidably mounted on the top of the support base, clamping boxes fixedly mounted at both ends of the connecting plate, two sliding plates symmetrically mounted and slidably connected to the clamping boxes, a clamping plate fixedly mounted on the top of each sliding plate, a pad slidably connected between the two sliding plates, and oblique holes opened on both sliding plates. The two ends of the pad are slidably connected to the two sliding plates along the oblique holes.

[0005] Furthermore, a number of springs arranged at equal intervals are connected between the bottom end of the pad and the bottom end of the inside of the clamping box.

[0006] Furthermore, the support base includes a mounting plate, a support rod, and a horizontal plate. The support rod is fixed to the top of the mounting plate, and the horizontal plate is fixed to the top of the support rod. The top of the horizontal plate is provided with several parallel sliding grooves.

[0007] Furthermore, the bottom end of the connecting plate is fixed with several slide rails that cooperate with the slide groove, and the length of the slide rails is greater than the length of the horizontal plate.

[0008] Furthermore, the inner wall of the clamp box is provided with an installation groove, in which a limiting toothed plate is slidably installed. The clamp box is provided with a bolt that penetrates into the installation groove. One end of the bolt located inside the installation groove is rotatably connected to the limiting toothed plate. The side of the pad near the installation groove is provided with a tooth groove, and the side of the limiting toothed plate near the pad is provided with ratchet teeth that cooperate with the tooth groove.

[0009] Furthermore, ear plates are fixedly connected to both sides of the lower end of the pad, and the end of the ear plate away from the pad is slidably installed in the oblique hole.

[0010] Furthermore, the top of the pad has an arc-shaped structure.

[0011] Furthermore, reinforcing ribs are provided between the horizontal plate and the two clamping boxes.

[0012] Furthermore, both clamping plates have anti-slip textures on adjacent sides.

[0013] Furthermore, several reinforcing ribs are connected between the support rod and the mounting plate, and between the support rod and the cross plate.

[0014] The technical solution of this invention provides a pipeline connection support and protection device, which has the following advantages: the device lowers the pad after the pipeline contacts the pad, and the pad, in conjunction with the inclined hole on the sliding plate, drives two clamping plates to clamp and limit the side wall of the pipeline, so that the pipeline can be stably placed on the clamping box. Furthermore, through the sliding cooperation between the connecting plate and the support seat, the device can make a certain distance displacement while clamping the pipeline, thus being suitable for situations where steam pipelines are displaced due to thermal expansion and contraction. The device has a compact structure, high safety, and strong practicality. Attached Figure Description

[0024] Example 1

[0025] like Figures 1-4 As shown, a pipeline connection support and protection device includes a support base, a connecting plate 4 slidably mounted on the top of the support base, and clamping boxes 6 fixed at both ends of the connecting plate 4. Specifically, the support base includes a mounting plate 1, a support rod 2, and a horizontal plate 3. The support rod 2 is fixed to the top of the mounting plate 1, and the horizontal plate 3 is fixed to the top of the support rod 2. The top of the horizontal plate 3 is provided with several parallel sliding grooves 301. The sliding grooves 301 are through grooves arranged along the length direction of the horizontal plate 3. The bottom end of the connecting plate 4 is fixed with several slide rails 5 that cooperate with the sliding grooves 301. The length of the slide rails 5 is greater than the length of the horizontal plate 3, so that the connecting plate 4 can slide along the sliding grooves 301 through the slide rails 5.

[0026] Furthermore, several reinforcing ribs connect the support rod 2 to the mounting plate 1 and to the cross plate 3. The mounting plate 1 has several mounting holes evenly distributed along its circumference. These holes are used to fix the support base, thereby fixing the position of the entire device. Reinforcing ribs are also provided between the cross plate 3 and the two clamping boxes 6. The reinforcing ribs enhance the connection strength between the two connecting components and increase their resistance to deformation.

[0027] Two sliding plates 9 are symmetrically installed inside the clamping box 6 and are slidably connected to it. Each sliding plate 9 has a clamping plate 12 fixed at the top. The two clamping plates 12 have anti-slip textures on their adjacent sides to prevent slipping. A pad 7 is slidably connected between the two sliding plates 9. Both sliding plates 9 have oblique holes 10. The two ends of the pad 7 are slidably connected to the two sliding plates 9 along the oblique holes 10. Specifically, ear plates 8 are fixedly connected to both sides of the lower end of the pad 7. The end of the ear plate 8 away from the pad 7 is slidably installed in the oblique hole 10.

[0028] A number of equally spaced springs 11 connect the bottom end of the pad 7 to the bottom end of the clamping box 6. When the pipeline is lifted, the pad 7 can automatically rise under the action of the springs 11. During the automatic lifting process, the clamping plates 12 on both sides of the pipeline move away from the pipeline, so that the clamping plates 12 automatically release when the pipeline is lifted and automatically clamp when the pipeline is lowered. The top of the pad 7 has an arc-shaped structure to facilitate automatic alignment of the pipeline.

[0029] The inner wall of the clamping box 6 is provided with an installation groove 601. A limiting toothed plate 13 is slidably installed in the installation groove 601. The clamping box 6 is provided with a bolt 14 that passes through the installation groove 601. One end of the bolt 14 located inside the installation groove 601 is rotatably connected to the limiting toothed plate 13. The pad 7 is provided with a toothed groove 15 on the side near the installation groove 601. The limiting toothed plate 13 is provided with a ratchet that mates with the toothed groove 15 on the side near the pad 7. Rotating the bolt 14 can drive the ratchet on the limiting toothed plate 13 to engage with the toothed groove 15 on the pad 7, thereby limiting the pad 7 and further improving stability.

[0030] Working principle:

[0031] When the pipe is placed on the pad 7, the pad 7 descends under gravity. The ear plates 8 on both sides of the pad 7 cooperate with the inclined holes 10 on the slide plate 9 to drive the slide plate 9 to slide, thereby driving the two clamping plates 12 in the same clamping box 6 to move closer to each other. The two clamping plates 12 cooperate to clamp and limit the outer wall of the pipe. Rotating the bolt 14 can drive the ratchet on the limiting tooth plate 13 to engage with the tooth groove 15 on the pad 7 to limit the pad 7 and further improve stability. When the pipeline deforms and shifts due to thermal expansion and contraction, the slide rail 5 slides into the groove 301 on the horizontal plate 3, allowing the device to slide while stably clamping the pipeline. This allows the pipeline to shift a certain distance while being stably clamped. When the pipeline is lifted, the pad 7 rises under the action of the spring 11, thereby driving the clamping plates 12 on both sides away from the pipeline. This device realizes the automatic clamping of the clamping plates 12 when the pipeline is pressed down and the automatic release of the clamping plates 12 when the pipeline is lifted. The device has a simple structure and is highly practical.

[0032] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, and not to limit them; although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present invention.
