Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of cement pipes, in particular to a port reinforced cement pipe. Background Art
[0002] Cement pipe, also known as concrete pipe, is made of cement and steel bars. Due to its good corrosion resistance, strength and long service life, cement pipe is widely used in various fields. Since the pipe mouth of the cement pipe is the connection point of the pipe body, it will concentrate on the tension, extrusion or twisting of the pipeline system, resulting in stress concentration, which is easy to cause cracks or breakage. In addition, during daily storage, if the cement pipe is lifted from a horizontal state to a vertical state, or the vertical pipe is placed in a horizontal state, the pipe mouth will first contact the ground. The cement pipe itself has a certain weight. When the pipe mouth contacts the ground, it will generate a large pressure. This pressure may exceed the bearing capacity of the pipe mouth, resulting in damage to the pipe mouth.
[0003] Based on the above situation, we propose a port reinforced cement pipe to solve the above problems. Utility Model Content
[0004] The utility model provides a cement pipe with reinforced ports, so as to solve the problem that the cement pipe ports are easily broken and damaged in the prior art.
[0005] The technical problem solved by the utility model is achieved by the following technical solutions:
[0006] A port-reinforced cement pipe comprises a pipe body and a port protective member, wherein both ends of the pipe body are provided with pipe mouths integrally formed with the pipe body, the outer diameter of the pipe mouths is smaller than the outer diameter of the pipe body, and the inner diameter of the pipe mouths is the same as the inner diameter of the pipe body, the port protective member is connected to the pipe mouths for reinforcing and protecting the pipe mouths, and the port protective member comprises a pressure-bearing portion, the end of the pressure-bearing portion is flush with the pipe mouths and wrapped around the outer wall of the pipe mouths.
[0007] Preferably, the port protection member also includes a reinforcement ring and a plurality of reinforcement plates, wherein the reinforcement ring is located inside the pipe mouth and connected to the pressure-bearing part, and the plurality of reinforcement plates are connected to the inner wall of the reinforcement ring and are equidistantly arranged around the centerline axis of the reinforcement ring.
[0008] Preferably, the longitudinal cross-section of the pressure-bearing portion is straight at one end away from the pipe mouth.

[0010] Preferably, reinforcing ribs are connected between the port protection members located on the two pipe mouths, and the reinforcing ribs are equidistantly arranged around the central axis of the pipe body.
[0011] Preferably, the outer diameter of the pressure-bearing portion is equal to the outer diameter of the tube body.
[0012] The beneficial effects of the utility model are:
[0013] By arranging a port protection part on the pipe mouth, the pressure resistance of the pipe mouth is enhanced. At the same time, the outer diameter of the pipe mouth is smaller than the outer diameter of the pipe body. When the pipe body is placed horizontally on the ground, the pipe mouth can be prevented from directly contacting the ground and causing damage to the pipe mouth. The pressure-bearing part is in contact with the ground to improve the protection effect of the pipe mouth. When the pipe body is tilted from a vertical state to a horizontal state or straightened from a horizontal state to a vertical standing state, the pressure-bearing part is in direct contact with the ground to protect the pipe mouth, improve the strength of the pipe mouth, and reduce the possibility of breakage or damage to the pipe mouth.

[0022] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below with reference to specific illustrations.
[0023] Reference Figure 1-Figure 6 As shown, a port reinforced cement pipe comprises a pipe body 1 and a pipe mouth 11 integrally formed at both ends of the pipe body 1. When the pipe body 1 is changed from a vertical placement state to a horizontal placement state or from a horizontal placement state to a vertical placement state, as shown in FIG. Figure 1 As shown, there will be a certain angle between the pipe body 1 and the ground, and the edge of the pipe mouth 11 will conflict with the ground. For some hard ground, the pipe mouth 11 is usually made of concrete, and under the action of the gravity of the pipe body 1 itself, the pipe mouth 11 is easily broken and damaged. In view of the above problems, this solution will propose the following technical solutions to solve them:
[0024] A port guard 2 is provided on the pipe mouth 11 to reinforce and protect the pipe mouth 11. The port guard 2 includes a pressure-bearing portion 21, which is made of metal. The end of the pressure-bearing portion 21 is flush with the pipe mouth 11 and wrapped around the outer wall of the pipe mouth 11. When the pipe body 1 collides with the ground and forms a certain angle, the pressure-bearing portion 21 directly contacts the ground to protect the pipe mouth 11, thereby preventing the pipe mouth 11 from directly contacting the ground, thereby preventing the pipe mouth 11 from being broken and damaged. The outer diameter of the pipe mouth 11 is smaller than the outer diameter of the pipe body 1. When the pipe body 1 is in a horizontal position, the pipe mouth 11 will not contact the ground, thereby further reducing the possibility of damage to the pipe mouth 11. The inner diameter of the pipe mouth 11 is the same as the inner diameter of the pipe body 1, and the material fluidity will not be affected by the different inner diameters.
[0025] Further, such as Figure 3 As shown, the port guard 2 also includes a reinforcement ring 22 and a plurality of reinforcement plates 23. The reinforcement ring 22 is located inside the pipe mouth portion 11 and is connected to the pressure portion 21 to improve the local stiffness and deformation resistance of the pipe mouth portion 11, which helps to reduce the possibility of the pipe mouth portion 11 breaking when subjected to external force or stress. The plurality of reinforcement plates 23 are connected to the inner wall of the reinforcement ring 22 and are equidistantly arranged around the center axis of the reinforcement ring 22, and the interior of the reinforcement ring 22 is supported by the plurality of reinforcement plates 23. When the pipe mouth portion 11 is subjected to external bearing force and the bearing force is transferred to the reinforcement ring 22, the bearing force is evenly dispersed through the reinforcement plates 23, thereby improving the deformation resistance of the reinforcement ring 22 and extending the service life.
[0026] Furthermore, the outer diameter of the pressure-bearing portion 21 is equal to the outer diameter of the tube body 1. When the tube body 1 is placed horizontally, the pressure-bearing portion 21 and the tube body 1 are in contact with the ground synchronously, thereby sharing part of the pressure of the tube body 1. The pressure-bearing portion 21 can be made of metal material, which can further protect the pipe mouth and avoid damage to the pipe mouth 11 caused by wear between the pipe mouth 11 and the ground.
[0027] In order to further protect the nozzle 11, in the first embodiment of the present utility model, as shown in FIG. Figure 5 As shown, the longitudinal cross-section of the pressure portion 21 is straight at one end away from the nozzle portion 11. When a certain angle is formed between the nozzle portion 11 and the ground, the pressure portion 21 contacts the ground to reduce damage to the nozzle portion 11. However, when the edges of the pressure portion 21 come into contact with the ground, wear of the edges of the pressure portion 21 may occur.
[0028] Further, such as Figure 6 As shown, in the second embodiment of the utility model, the longitudinal cross-section of the pressure portion 21 in the first embodiment, which is straight at one end away from the nozzle 11, is replaced by an arc-shaped longitudinal cross-section at one end away from the nozzle 11. When a certain angle is generated between the nozzle 11 and the ground, the pressure on the tube body 1 can be more evenly dispersed to a larger area of the ground through the contact between the curved surface of the pressure portion 21 and the ground, thereby reducing the damage to the ground and the tube body 1 caused by excessive local pressure and avoiding wear on the edges of the pressure portion 21.
[0029] Furthermore, reinforcing ribs 3 are connected between the port guards 2 located on the two pipe mouths 11. The reinforcing ribs 3 are equidistantly arranged around the central axis of the pipe body 1. The port guards 2 in the two pipe mouths 11 can be connected through the reinforcing ribs 3, so that the overall structure of the pipe body 1 is more stable, can better withstand the effects of external and internal forces, and prevent local damage caused by inconsistent deformation of the pipe mouth 11.
[0030] The above shows and describes the basic principle and main features of the utility model and the advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments. The above embodiments and descriptions are only for explaining the principle of the utility model. Without departing from the spirit and scope of the utility model, the utility model may have various changes and improvements, which fall within the scope of the utility model to be protected.
