Description

Technical Field

[0001] The present invention relates to the technical field related to pipeline heat preservation, and particularly to a heat preservation device for pipeline joints. Background Art

[0002] The heat preservation pipe is short for the heat-insulating pipeline. The heat preservation pipe is used for the transportation of liquids, gases and other media, and is used for the heat insulation engineering of pipelines in petroleum, chemical industry, aerospace, hot spring, military, central heating, central air conditioning, municipal administration, etc. The heat preservation pipe is an important factor affecting energy conservation. The research and application of heat preservation pipes have been increasingly valued by countries around the world. After the 1970s, foreign countries generally attached importance to the production and application of heat preservation pipes, striving to greatly reduce the consumption of energy, thereby reducing environmental pollution and the greenhouse effect. The foreign heat preservation industry has a long history, and new heat preservation materials are constantly emerging. Before 1980, the development of heat preservation pipes in China was very slow. Only a few heat preservation factories could produce a small amount of underground directly buried heat preservation pipes. However, after more than 30 years of efforts, especially after nearly 10 years of rapid development, many products have emerged from scratch, from single to diversified, and the quality has increased from low to high, and the application has become more and more common. Polyurethane materials are the most commonly used heat preservation materials in the world at present. At present in the market, the heat preservation of the joints between pipelines is not well done, and the heat preservation device is prone to shift and has poor fixity. Summary of the Invention

[0003] The present invention is to overcome the deficiencies of easy shift and poor stability in the prior art, and provides a heat preservation device for pipeline joints with good stability.

[0004] In order to achieve the above object, the present invention adopts the following technical solutions:

[0005] A heat preservation device for pipeline joints includes a heat preservation module, a stability module, an upper connection module, a lower connection module and a support module. Both the upper connection module and the lower connection module are connected to the heat preservation module. The upper connection module is connected to the lower connection module. The stability module is connected to the heat preservation module. The support module is placed at the bottom end of the heat preservation module and is connected to the heat preservation module.

[0006] Both the upper connection module and the lower connection module are connected to the heat preservation module. The upper connection module is connected to the lower connection module. The heat preservation of the pipeline joint is carried out through the heat preservation module. The upper and lower stability of the device and the tension of the heat preservation module are carried out through the upper connection module and the lower connection module. The stability module is connected to the heat preservation module. The support module is placed at the bottom end of the heat preservation module and is connected to the heat preservation module. The whole heat preservation device is supported through the support module. The heat preservation device is stably reinforced through the stability module, so that the device will not move left and right. Through the cooperation of the upper connection module, the lower connection module and the stability module, the purpose of not being prone to shift and having good stability is achieved.

[0007] Preferably, the heat preservation module includes a first connecting block and a second connecting block. The first connecting block is located above the second connecting block. The first connecting block and the second connecting block have the same structure. The shape of the first connecting block is U-shaped. Heat preservation blocks are connected to the inner sides of both the first connecting block and the second connecting block. The heat preservation blocks are matched with and connected to the first connecting block. The U-shaped opening end of the first connecting block faces downward, and the U-shaped opening end of the second connecting block faces upward. The upper connecting module is connected to the first connecting block, the lower connecting module is connected to the second connecting block, one end of the stabilizing module is connected to the first connecting block, and the other end of the stabilizing module is connected to the second connecting block. The first connecting block is connected to the second connecting block through the cooperation of the upper connecting module and the lower connecting module. The supporting module is placed at the bottom end of the second connecting block and is connected to the second connecting block. The heat preservation of the joint of the heat preservation pipeline can be achieved through the heat preservation blocks. By the separated first connecting block and second connecting block, pipelines with different diameters can be adapted. Both the first connecting block and the second connecting block are U-shaped and together form a circle, which can improve the heat preservation effect. The heat preservation module is reinforced through the stabilizing module, and the stability of the heat preservation module is improved through the supporting module.

[0008] Preferably, the upper connecting module includes several connecting plates and several connecting columns. The connecting plates are connected to the first connecting block and are respectively placed on the left and right sides of the first connecting block. The shape of the connecting plates matches the shape of the first connecting block. The connecting columns are connected to the connecting plates and are respectively placed at both ends of the connecting plates. Connecting plates and connecting columns are provided at both the front and rear ends of the first connecting block, which improves the stability of the upper connecting module and the heat preservation module.

[0009] Preferably, the lower connecting module includes several connecting plates and several connecting rods. The connecting plates are connected to the second connecting block and are respectively placed on the left and right sides of the second connecting block. The shape of the connecting plates matches the shape of the second connecting block. The connecting rods are connected to the connecting plates and are respectively placed at both ends of the connecting plates. Connecting plates and connecting columns are provided at both the front and rear ends of the second connecting block, which improves the stability of the lower connecting module and the heat preservation module.

[0010] Preferably, the connecting column is provided with a connecting groove matching the connecting rod. The connecting rod is slidably connected to the connecting column through the connecting groove. A spring is arranged inside the connecting rod and connected to the connecting rod. The side surface of the connecting rod is provided with a clamping block and a hole. The spring is placed in the hole. The clamping block matches the hole and is connected to the connecting rod through the spring. The clamping block includes a flat surface and a curved surface. The flat surface is located below the curved surface. The connecting column is provided with a plurality of clamping holes matching the clamping block. The clamping holes are evenly distributed on the side surface of the connecting column and communicate with the connecting groove. Through the cooperation of the hole and the spring, the clamping block can freely expand and contract on the connecting rod. When the connecting rod is gradually pushed into the connecting groove of the connecting column, the curved surface of the clamping block contacts the connecting column and can be easily pushed further inward. When the heat preservation block is in close contact with the pipeline, the connecting rod cannot be pushed further. The clamping block is clamped into the clamping hole to achieve fixation, and through the flat surface of the clamping block being stressed, it cannot move back, thus achieving fixation.

[0011] Preferably, the stabilizing module includes a plurality of first fixing plates and a plurality of second fixing plates. The number of the first fixing plates is the same as that of the second fixing plates. The first fixing plates are connected to the first connecting block and arranged at both ends of the first connecting block.

A plurality of bolts are arranged on the first fixing plates and connected to the first fixing plates. A plurality of nuts matching the bolts are arranged on the second fixing plates. The nuts are located on the lower end surface of the second fixing plates. The number of the bolts is the same as that of the nuts. The first fixing plates are connected to the second fixing plates through the cooperation of the bolts and the nuts. When the heat preservation module is tensioned with the pipeline through the cooperation of the upper connecting module and the lower connecting module, it can be fixed by the fixing module. By screwing the nuts on the second fixing plates onto the bolts on the first fixing plates, the purpose of strengthening the fixing module is achieved.

[0012] Preferably, the supporting module includes a third connecting block, a slider and a hydraulic device. The slider is arranged at the bottom end of the second connecting block and connected to the second connecting block. The bottom end of the slider is connected with a sliding head. The third connecting block is provided with a sliding groove matching the sliding head. The sliding head is placed in the sliding groove. The slider is slidably connected to the third connecting block through the cooperation of the sliding head and the sliding groove. The hydraulic device is arranged at the bottom end of the third connecting block and connected to the third connecting block. Through the cooperation of the sliding head and the sliding groove, the third connecting block and the hydraulic device can be separated from or connected to the heat preservation module, and the supporting module can be freely selected to be used or not used. When the sliding head slides into the inner side of the sliding groove, the height of the third connecting block can be lifted through the hydraulic device to achieve the purpose of supporting the heat preservation device.

[0013] Preferably, a storage groove is arranged inside the third connecting block. The storage groove matches the sliding head. The storage groove is located below the sliding groove and communicates with the sliding groove. When the sliding head slides leftward in the sliding groove to the position of the storage groove, the position of the third connecting block is lifted through the hydraulic device to place the sliding head in the storage groove, thereby restricting the position of the sliding head so that it cannot move left and right continuously.

[0014] The beneficial effects of the present invention are as follows: it is not prone to deviation and has good stability; it has strong adjustment performance and can adapt to pipes of different thicknesses; the stability of the device can be improved by adjusting the support module.

The connecting rods 11 are connected to the connecting plates 9 and are respectively placed at both ends of the connecting plates 9. As Figure 4 and Figure 5 shown, a connection groove 12 matching the connecting rod 11 is provided on the connecting column 10. The connecting rod 11 is slidably connected to the connecting column 10 through the connection groove 12. A spring 13 is provided inside the connecting rod 11. The spring 13 is connected to the connecting rod 11. A clamping block 14 and a hole are provided on the side surface of the connecting rod 11. The spring 13 is placed inside the hole. The clamping block 14 matches the hole. The clamping block 14 is connected to the connecting rod 11 through the spring 13. As Figure 6 shown, the clamping block 14 includes a flat surface 15 and a curved surface 16. The flat surface 15 is located below the curved surface 16. Several clamping holes 17 matching the clamping block 14 are provided on the connecting column 10. The clamping holes 17 are evenly distributed on the side surface of the connecting column 10. The clamping holes 17 communicate with the connection groove 12.

[0027] As Figure 3As shown in the figure, the stabilizing module 2 includes a plurality of first fixing plates 18 and a plurality of second fixing plates 19. The number of the first fixing plates 18 is the same as that of the second fixing plates 19. The first fixing plates 18 are connected to the first connecting block 6 and are placed at both ends of the first connecting block 6.

First, insert the connecting rod 11 into the connecting groove 12 of the connecting column 10 and push the connecting rod 11 upward. During the upward pushing process, since the curved surface 16 of the clamping block 14 first contacts the connecting column 10, the clamping block 14 contracts into the clamping block 14 through the cooperation of the spring 13 and the hole. Even if it encounters the clamping hole 17, it can be pushed into the connecting rod 11. When the heat preservation block is in close contact with the heat preservation pipeline, the connecting rod 11 cannot be pushed upward continuously. At this time, the upper connecting module 3 and the lower connecting module 4 are connected to the heat preservation module 1, and the clamping block 14 is placed on the clamping hole 17 and the force-bearing surface becomes the flat surface 15, so it cannot contract into the connecting rod 11. Then turn the nut 21 into the bolt 20 to keep the stabilizing module 2 firmly connected to the heat preservation module 1. Finally, the support module 5 can be selected to be used or not according to the actual situation. If the support module 5 is to be used, place the sliding head 25 in the sliding groove 26 of the third connecting block 22, slide the sliding head 25 to the left onto the storage groove 27, lift the third connecting block 22 through the hydraulic device 24 so that the sliding head 25 is placed in the storage groove 27 and remains stable, making the sliding head 25 unable to move. Finally, lift the third connecting block 22 through the hydraulic device 24 until it cannot be lifted anymore.
