Description

Technical Field

[0001] This utility model relates to the field of socket pipe technology, and in particular to steel socket pipe with strong support. Background Technology

[0002] Strongly supported steel socket pipes generally refer to pipes that use steel sockets at the joints. Common types include reinforced concrete steel socket pipes and steel-reinforced polyethylene (PE) spiral corrugated pipes with steel sockets.

[0003] Commonly used reinforced concrete steel socket pipes consist of three parts: reinforcing bars, concrete, and steel socket. The reinforcing bars act as a skeleton to bear tensile stress and prevent the pipe from cracking under stress; the concrete provides compressive strength, enabling the pipe to withstand external pressure; and the steel socket is used to connect the pipes, ensuring the sealing and stability of the joint.

[0004] Traditional steel sockets often lack reliable support components. The strength is usually increased by increasing the thickness of the steel, which not only wastes raw materials but also makes the socket pipe too heavy and difficult to transport.

[0005] The Chinese patent for stainless steel pipe fittings, application number CN201510338844.1, connects two sections of the pipe body 1 by forming an outwardly protruding annular socket step 2 at one end and an inwardly protruding spigot step 3 at the other end. Simultaneously, the diameter of the annular socket step 2 is limited to be greater than the diameter of the pipe body 1, while the diameter of the spigot step 3 is smaller than the diameter of the pipe body 1. This ensures that adjacent connecting pipes can be easily and conveniently inserted into the pipe body 1. The pipe body 1 and the annular socket step 2 are transitionally connected by a first arc 4 and a second arc 5. This serves to limit the movement of the pipe body 1, achieve a perfect connection with it, and also enable quick connection with other pipes. While this approach ensures a quick connection between the two pipe bodies 1, it results in an overly heavy socket pipe, which is inconvenient for transportation. If the thickness of the socket step 2 and the spigot step 3 is reduced to decrease the weight of the socket pipe, the structural strength of the socket step 2 and the spigot step 3 cannot be guaranteed. Under external force, the two may deform, and the spigot step 3 may not be able to be inserted into the socket step 2, thus preventing the two pipe bodies 1 from being effectively connected together. Utility Model Content

[0006] The main purpose of this utility model is to provide a steel socket pipe with strong support, so as to solve the problem that most steel sockets in related technologies do not have reliable support components and usually increase the thickness of steel to improve their strength.

[0007] To achieve the above objectives, according to one aspect of the present invention, a steel socket pipe with strong support is provided, comprising a pipe for providing a passage for liquid, and further comprising: a socket portion fixedly disposed at the end of the pipe, the socket portion for connecting two adjacent pipes, the socket portion comprising an annular portion and a connecting portion, the annular portion being connected to the pipe through the connecting portion, the annular portion being used to accommodate the tail end of another adjacent pipe.

[0008] Furthermore, the connecting part is in the shape of a hollow frustum, and the connecting part includes an outer ring, an inner ring, a cavity, and several support blocks.

[0009] Furthermore, the inner ring is circular, and the outer ring is hollow frustum. The inner ring is fixed inside the outer ring, and the ends of the inner and outer rings are both fixedly connected to the pipe, thus fixing the ring portion to the pipe. The angle between the inner and outer rings is 10° to 15°, preferably 12° in this embodiment, so that a wedge-shaped cavity is formed between the inner and outer rings. This reduces the weight of the connection part while accommodating a larger support block. The support block supports the inner and outer rings to prevent deformation, thereby improving the mechanical strength and load-bearing capacity of the connection part.

[0010] The support block is triangular in shape, with the same cross-sectional shape as the chamber. It fits perfectly between the outer and inner rings, increasing the contact area between them and strengthening the connection strength of the joint. At the same time, it ensures that the inner space of the inner ring is cylindrical, which facilitates the insertion of the pipe tail and connects two adjacent pipes, extending the total length of the pipe to adapt to different usage scenarios.

[0011] Furthermore, a cavity is formed between the inner ring and the outer ring, and the support blocks are all located in the cavity. One side of each support block is fixedly connected to the inner surface of the outer ring, and the other side is fixedly connected to the outer surface of the inner ring.

[0012] Furthermore, the ring portion includes an outer ring, an inner ring, a ring cavity, and several supporting portions, with the outer ring fixedly disposed at the end of the outer ring and the inner ring fixedly disposed at the end of the inner ring.

[0013] Furthermore, an annular cavity is formed between the outer ring and the inner ring, and the supporting parts are all located within the annular cavity and are fixedly connected to both the outer ring and the inner ring.

[0014] Furthermore, the support portion includes two support bars, several bases, several support rods, and several ribs. The two support bars are arranged opposite to each other, with the outer support bar fixedly connected to the outer ring and the inner support bar fixedly connected to the inner ring.

[0015] The support bar is trapezoidal, with its large end fixedly connected to the outer or inner ring, increasing the contact area with the outer or inner ring, reducing the pressure on the outer and inner rings, and preventing them from deforming due to pressure; the base is frustum-shaped, increasing the contact area with the support bar, reducing the pressure on the support bar, preventing the support bar from being squeezed and deformed by the support rod, and increasing the support strength of the support part.

[0016] Furthermore, the pedestals are all fixedly mounted on the outside of the support bars, the support rods are all fixedly mounted between two opposing pedestals, and the ribs are all fixedly mounted on the outer ring of the support rods to increase the compressive strength of the support rods.

[0017] Compared with the prior art, this utility model has the following beneficial effects: the support block abuts against the inner ring from all sides, distributing the pressure evenly on the outer ring, which can reduce the weight of the joint and enhance the load-bearing capacity of the inner ring, preventing it from being squeezed and deformed, and reducing the sealing performance of the socket; the support strip increases the contact area between the support rod and the outer and inner rings, preventing the outer and inner rings from being squeezed and deformed by the support rod; the platform increases the contact area between the support rod and the support strip, preventing the support strip from being squeezed and deformed by the support rod; the rib increases the compressive strength of the support rod; the support strip, platform, and support rod together increase the load-bearing capacity of the ring, preventing it from being squeezed and deformed, and reducing the sealing performance of the socket; the structural strength can be improved without increasing the thickness of the steel in the socket, which not only saves raw materials but also facilitates transportation.

[0026] To further illustrate the technical means and effects adopted by this utility model in order to achieve the intended utility model purpose, the following detailed description of the specific implementation methods, structure, features and effects of this utility model is provided in conjunction with the accompanying drawings and preferred embodiments.

[0027] Please see Figures 1 to 5 This embodiment provides a steel socket pipe with strong support, including a pipe 1 for providing a channel for liquid, and a socket 2 fixedly disposed at the end of the pipe 1. The socket 2 is used to connect two adjacent pipes 1. The socket 2 includes an annular portion 21 and a connecting portion 22. The annular portion 21 is connected to the pipe 1 through the connecting portion 22. The annular portion 21 is used to accommodate the tail of another adjacent pipe 1.

[0028] The connecting part 22 is in the shape of a hollow frustum and includes an outer ring 221, an inner ring 222, a cavity 223 and several support blocks 224.

[0029] The inner ring 222 is circular, and the outer ring 221 is hollow frustum. The inner ring 222 is fixed inside the outer ring 221. The ends of the inner ring 222 and the outer ring 221 are both fixedly connected to the pipe 1, fixing the ring part 21 to the pipe 1. The included angle between the inner ring 222 and the outer ring 221 is 10° to 15°, preferably 12° in this embodiment, so that a wedge-shaped cavity 223 is formed between the inner ring 222 and the outer ring 221. This reduces the weight of the connecting part 22 while accommodating a larger support block 224. The support block 224 supports the inner ring 222 and the outer ring 221 to prevent them from deforming, thereby improving the mechanical strength and load-bearing capacity of the connecting part 22.

[0030] The support block 224 is triangular in shape and has the same cross-sectional shape as the chamber 223. It fits perfectly between the outer ring 221 and the inner ring 222, increasing the contact area between the outer ring 221 and the inner ring 222, strengthening the connection strength of the connecting part 22, and ensuring that the inner space of the inner ring 222 is cylindrical, which facilitates the insertion of the tail of the pipe 1, connecting two adjacent pipes 1, and extending the total length of the pipe 1 to adapt to different usage scenarios.

[0031] A cavity 223 is formed between the inner ring 222 and the outer ring 221. All support blocks 224 are located in the cavity 223. One side of each support block 224 is fixedly connected to the inner surface of the outer ring 221, and the other side is fixedly connected to the outer surface of the inner ring 222.

[0032] The ring portion 21 includes an outer ring 211, an inner ring 212, a ring cavity 213 and several support portions 214. The outer ring 211 is fixedly disposed at the end of the outer ring 221, and the inner ring 212 is fixedly disposed at the end of the inner ring 222.

[0033] An annular cavity 213 is formed between the outer ring 211 and the inner ring 212. The support part 214 is located in the annular cavity 213 and is fixedly connected to both the outer ring 211 and the inner ring 212.

[0034] The support part 214 includes two support bars 215, several bases 216, several support rods 217 and several ribs 218. The two support bars 215 are arranged opposite to each other. The outer support bar 215 is fixedly connected to the outer ring 211, and the inner support bar 215 is fixedly connected to the inner ring 212.

[0035] The support bar 215 is trapezoidal, with its large end fixedly connected to the outer ring 211 or the inner ring 212, increasing the contact area with the outer ring 211 or the inner ring 212, reducing the pressure on the outer ring 211 and the inner ring 212, and preventing them from deforming due to pressure; the base 216 is frustum-shaped, increasing the contact area with the support bar 215, reducing the pressure on the support bar 215, preventing the support bar 215 from being squeezed and deformed by the support rod 217, and increasing the support strength of the support part 214.

[0036] The pedestals 216 are all fixedly installed on the outside of the support bars 215, the support rods 217 are all fixedly installed between the two opposing pedestals 216, and the ribs 218 are all fixedly installed on the outer ring of the support rods 217 to increase the compressive strength of the support rods 217.

[0037] The steel socket pipe is made of HRB500 high-strength hot-rolled ribbed steel bars, with a standard yield strength of 500MPa. It has the characteristics of high strength, good ductility, excellent weldability and high durability. The steel socket pipe made of this steel has high strength and good support performance.

[0038] Insert the spigot of the second socket pipe into the socket portion 2 of the first socket pipe, and connect them sequentially until the length of the connected socket pipes meets the usage requirements. After the spigot is inserted into the socket portion 2 of another socket pipe, the inner ring 212 and inner ring 222 are pressed outwards. The support block 224 abuts against the inner ring 222 from all sides, distributing the pressure evenly on the outer ring 221. This reduces the weight of the connecting part 22 and enhances the load-bearing capacity of the inner ring 222, preventing it from being squeezed and deformed, thus reducing the sealing performance of the socket portion 2. At the same time, the support part 214 abuts against the inner ring from all sides. 212, the pressure is evenly distributed on the outer ring 211. The support bar 215 increases the contact area between the support rod 217 and the outer ring 211 and the inner ring 212, preventing the outer ring 211 and the inner ring 212 from being squeezed and deformed by the support rod 217. The platform 216 increases the contact area between the support rod 217 and the support bar 215, preventing the support bar 215 from being squeezed and deformed by the support rod 217. The support bar 215, platform 216 and support rod 217 together increase the load-bearing capacity of the ring portion 21, preventing it from being squeezed and deformed, and reducing the sealing performance of the socket portion 2.

[0039] The support block 224 abuts against the inner ring 222 from all sides, distributing the pressure evenly on the outer ring 221. This reduces the weight of the connecting part 22 and enhances the load-bearing capacity of the inner ring 222, preventing it from being squeezed and deformed, thus reducing the sealing performance of the socket 2. The support bar 215 increases the contact area between the support rod 217 and the outer ring 211 and inner ring 212, preventing the outer ring 211 and inner ring 212 from being squeezed and deformed by the support rod 217. The base 216 increases the contact area between the support rod 217 and the support bar 215, preventing the support bar 215 from being squeezed and deformed by the support rod 217. The rib 218 increases the compressive strength of the support rod 217. The support bar 215, base 216, and support rod 217 together increase the load-bearing capacity of the ring part 21, preventing it from being squeezed and deformed, thus reducing the sealing performance of the socket 2. This socket pipe can improve its structural strength without increasing the steel thickness of the socket part 2, saving raw materials and facilitating transportation.
