Description

Technical Field

[0001] This utility model relates to the field of trench steel clamp technology, and in particular to trench steel clamps suitable for pipeline burial construction. Background Technology

[0002] Grooved steel clamps are mechanical components widely used for pipe connection and fixing, especially in water supply and drainage, fire protection, HVAC and other fields. Through unique groove design and rigid structure, they can achieve quick connection and reliable fixing of pipes. They have the advantages of convenient installation. Grooved steel clamps are mainly composed of clamps, gaskets and connecting bolts. The clamps are usually semi-circular with grooves on the inside that match the pipe grooves.

[0003] When existing grooved steel clamps are buried together with pipelines, they are directly exposed to the outside because there is no external protective device. As a result, soil, sand and gravel will come into direct contact with the grooved steel clamps. Over time, this will cause wear on the surface of the grooved steel clamps, and the moisture inside the soil and sand will also cause corrosion of the grooved steel clamps, resulting in loosening of the connection parts and affecting their sealing performance. Utility Model Content

[0004] The purpose of this utility model is to solve the problem that the external protective device of the trench steel clamp is not available, and to propose a trench steel clamp suitable for pipeline laying construction.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A trench clamp suitable for pipeline burial construction, including a pipeline, wherein the pipeline is equipped with a protective mechanism that can protect the trench clamp after burial.

[0007] The protective mechanism includes an upper clamp and a lower clamp placed on the pipe. A sealing ring is engaged inside the upper clamp and the lower clamp. The upper clamp and the lower clamp are equipped with a protective mechanism to improve the durability of the groove clamp. The upper clamp and the lower clamp are also equipped with a stabilizing component to improve the sealing effect.

[0008] As a further description of the above technical solution:

[0009] The protective mechanism includes insertion holes on both sides of the lower clamping block, an upper housing and a lower housing used in conjunction with the upper and lower clamping blocks, an insertion rod fixedly installed on the inner surface of the upper housing, mounting seats fixedly installed on both sides of the upper and lower housings, a moving groove opened inside the mounting seat, a locking block rotatably connected inside the moving groove, a protrusion fixedly installed on the surface of the moving groove, and a push rod fixedly installed on one side of the locking block.

[0010] As a further description of the above technical solution:

[0011] The size of the insertion rod is adapted to the insertion hole, the protrusion is made of flexible material, and the locking block is semi-circular.

[0012] As a further description of the above technical solution:

[0013] The stabilizing component includes grooves formed inside the upper and lower clamping blocks. A threaded rod is threadedly connected inside the groove. A stop plate is rotatably installed at one end of the threaded rod. Fixing blocks are fixedly installed at both ends of the lower clamping block. An extension block is inserted into the interior of the fixing block. A spring is fixedly installed between the extension block and the fixing block. Rectangular slots are formed at both ends of the upper clamping block.

[0014] As a further description of the above technical solution:

[0015] Both ends of the threaded rod extend to the outside of the groove, and the abutment is arc-shaped and contacts the outer surface of the sealing ring.

[0016] As a further description of the above technical solution:

[0017] The top of the extension block is set as an inclined surface, and the size of the rectangular groove is adapted to the fixed block.

[0018] In summary, due to the adoption of the above technical solution, the beneficial effects of this utility model are:

[0019] 1. By incorporating a protective mechanism, with an upper and lower housing fitted over the upper and lower clamping blocks, it effectively prevents debris such as mud, sand, and dust generated during construction from entering the interior of the trench clamp, protecting critical components such as internal connecting bolts and preventing jamming or damage caused by debris. It also prevents rainwater and mud from entering, improving the protective effect. Rotating the push rod causes the clamping blocks to rotate, which completes the self-locking of the upper and lower housings, enabling quick fixation.

[0020] 2. With the stabilizing component, when the upper and lower clamping blocks are combined, the fixing block is also inserted into the rectangular groove. At the same time as insertion, the extension block is squeezed back by the rectangular groove through the top inclined surface. After the fixing block is fully inserted into the rectangular groove, the extension block is reset by the reaction force of the spring and provides a quick fixing effect for the upper and lower clamping blocks. By rotating the threaded rod, the abutment plate is moved, so that the abutment plate presses against the sealing ring, allowing the sealing ring to fit tightly against the pipe connection and improving the sealing effect.

[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0032] like Figure 1 - Figure 7 As shown, the present invention provides a trench clamp suitable for pipeline burial construction, including a pipeline 10, on which a protective mechanism 20 is installed to protect the trench clamp after burial.

[0033] The protective mechanism 20 includes an upper clamping block 21 and a lower clamping block 22 placed on the pipe 10. The upper clamping block 21 and the lower clamping block 22 are fitted with sealing rings 23. In use, the sealing rings 23 are respectively fitted into the upper clamping block 21 and the lower clamping block 22, and then the upper clamping block 21 and the lower clamping block 22 are placed at the connection of the pipe 10 and joined together. The upper clamping block 21 and the lower clamping block 22 are equipped with a protective mechanism 24 to improve the durability of the groove clamping. The upper clamping block 21 and the lower clamping block 22 are also equipped with a stabilizing component 25 to improve the sealing effect.

[0034] like Figure 2 - Figure 5 As shown, the protection mechanism 24 includes insertion holes 241 on both sides of the lower clamping block 22, an upper housing 242 and a lower housing 243 used in conjunction with the upper clamping block 21 and the lower clamping block 22. An insertion rod 244 is fixedly installed on the inner surface of the upper housing 242. After the upper housing 242 and the lower housing 243 are sleeved on the upper clamping block 21 and the lower clamping block 22, the insertion rod 244 will be inserted into the insertion hole 241, thereby limiting the upper housing 242 and the lower housing 243 after they are merged. Mounting seats 245 are fixedly installed on both sides of the upper housing 242 and the lower housing 243. The mounting seats 245 have a moving groove 246 inside. A locking block 247 is rotatably connected inside the moving groove 246. A protrusion 248 is fixedly installed on the surface of the moving groove 246. A push rod 249 is fixedly installed on one side of the locking block 247.

[0035] like Figure 5 As shown, after the upper housing 242 and the lower housing 243 are combined, the push rod 249 is pushed to cause the locking block 247 to start rotating, so that the two sets of locking blocks 247 are vertically aligned (as shown). Figure 2 As shown, the upper housing 242 and the lower housing 243 are self-locked between the two mounting bases 245. At the same time, the rotating push rod 249 is blocked by the protrusion 248. The protrusion 248 is squeezed and deformed by its own flexibility when the push rod 249 is pushed. After the push rod 249 stops rotating, the reset protrusion 248 plays a limiting role for the push rod 249. By connecting the upper housing 242 and the lower housing 243 to the outside of the upper clamping block 21 and the lower clamping block 22, it can effectively prevent soil, sand, dust and other debris generated during construction from entering the interior of the trench clamp, protect the internal connecting bolts and other key components, and avoid jamming or damage caused by the entry of debris. At the same time, it can also prevent rainwater, mud and sand from entering, thus improving the protective effect.

[0036] In more detail, the size of the insertion rod 244 is adapted to the socket 241, the insertion rod 244 can be inserted into the socket 241, the protrusion 248 is made of flexible material, and the locking block 247 is semi-circular.

[0037] like Figure 6 - Figure 7As shown, the stabilizing component 25 includes grooves 251 formed inside the upper clamping block 21 and the lower clamping block 22. A threaded rod 252 is threadedly connected inside the groove 251. A stop plate 253 is rotatably mounted on one end of the threaded rod 252. By rotating the threaded rod 252, the threaded rod 252 can drive the stop plate 253 to move. The moving stop plate 253 plays a pressing role on the sealing ring 23. Fixing blocks 254 are fixedly installed at both ends of the lower clamping block 22. An extension block 255 is inserted into the inside of the fixing block 254. A spring 256 is fixedly installed between the extension block 255 and the fixing block 254. Rectangular grooves 257 are formed at both ends of the upper clamping block 21.

[0038] In more detail, both ends of the threaded rod 252 extend to the outside of the groove 251, and the abutment 253 is arc-shaped and contacts the outer surface of the sealing ring 23.

[0039] In more detail, the top of the extension block 255 is set as an inclined surface, and the size of the rectangular groove 257 is adapted to the fixed block 254. After the upper clamping block 21 and the lower clamping block 22 are combined, the fixed blocks 254 located on both sides of the lower clamping block 22 will also be inserted into the rectangular groove 257. At the same time as insertion, the extension block 255 is squeezed by the rectangular groove 257 through the inclined surface at the top, so that the extension block 255 moves towards the inside of the fixed block 254. After the fixed block 254 is fully inserted into the rectangular groove 257, the extension block 255 is reset by the reaction force of the spring 256. The extension block 255 plays a quick fixing effect on the upper clamping block 21 and the lower clamping block 22. Then, the upper clamping block 21 and the lower clamping block 22 are fixed again by screws.

[0040] Working principle: In use, the sealing ring 23 is respectively engaged inside the upper clamping block 21 and the lower clamping block 22. Then, the upper clamping block 21 and the lower clamping block 22 are placed at the connection of the pipe 10 and merged. The fixing blocks 254 located on both sides of the lower clamping block 22 are also inserted into the rectangular groove 257. At the same time as insertion, the extension block 255 is squeezed by the rectangular groove 257 through the top inclined surface, so that the extension block 255 moves towards the inside of the fixing block 254. After the fixing block 254 is fully inserted into the rectangular groove 257, the extension block 255 is reset by the reaction force of the spring 256. The extension block 255 achieves a quick fixing effect on the upper clamping block 21 and the lower clamping block 22. Then, the upper clamping block 21 and the lower clamping block 22 are fixed again by screws.

[0041] By rotating the threaded rod 252, the threaded rod 252 can drive the abutment plate 253 to move. The moving abutment plate 253 presses the sealing ring 23 tightly, so that the sealing ring 23 can fit tightly against the connection of the pipe 10, thereby improving the sealing effect.

[0042] After the upper housing 242 and the lower housing 243 are fitted onto the upper clamping block 21 and the lower clamping block 22, the insertion rod 244 will be inserted into the insertion hole 241, thereby limiting the combined upper housing 242 and lower housing 243.

[0043] At this time, pushing the push rod 249 causes the locking block 247 to start rotating, so that the two sets of locking blocks 247 are vertically positioned between the two mounting seats 245, locking the upper housing 242 and the lower housing 243. At the same time, the rotating push rod 249 is also blocked by the protrusion 248. The protrusion 248 is squeezed and deformed by its own flexibility when the push rod 249 is pushed. After the push rod 249 stops rotating, the reset protrusion 248 plays a limiting role for the push rod 249. By connecting the upper housing 242 and the lower housing 243 to the outside of the upper clamping block 21 and the lower clamping block 22, it can effectively prevent soil, sand, dust and other debris generated during construction from entering the interior of the trench clamp, protecting the internal connecting bolts and other key components, avoiding jamming or damage caused by debris entering. At the same time, it can also prevent rainwater, mud and sand from entering, improving the protective effect.

[0044] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
