Description

Technical Field

[0001] The utility model relates to the technical field of pipe jacking construction, in particular to an adjustable equalizing pressure ring used for rectangular pipe jacking construction. Background Art

[0002] Before the development of the equalizing ring, during the process of pipe jacking construction, construction workers usually used the cylinders on the cylinder rack to push the pipe sections forward. However, since the cylinder rack is designed as a U-shaped structure, there is an obvious empty area on the top. This structural defect will cause the force on the pipe sections to be unevenly distributed during the pipe jacking construction process, which will cause a series of problems. Specifically, when the force is uneven, the pipe sections may deviate from the predetermined axis, resulting in a decrease in construction accuracy. What is more serious is that this uneven force may also cause damage to the pipe sections themselves, or even cracks, thereby affecting the quality and safety of the entire project. Therefore, there is a need for a structure that can evenly transmit the cylinder jacking force to the pipe sections of the pipe jacking. Utility Model Content

[0003] The utility model provides an adjustable equalizing ring for rectangular pipe jacking construction to solve the technical problems existing in the known technology. The equalizing ring can evenly transmit the jacking force of the oil cylinder to the pipe section of the pipe jacking.

[0004] The utility model adopts the following technical solution to solve the technical problems existing in the known technology: an adjustable pressure equalizing ring for rectangular jacking construction, comprising a U-shaped frame and a rectangular frame, the U-shaped frame is arranged face to face with the jacking cylinder, the rectangular frame is arranged face to face with the jacking pipe section, and the U-shaped frame and the rectangular frame are fitted and fixed together.

[0005] The pressure equalizing ring is formed by connecting components through bolts I, and the components include two upper corner components and two lower corner components.

[0006] The pressure equalizing ring also includes at least one upper beam connecting member and at least one lower beam connecting member. The upper beam connecting member is connected between the two upper corner assemblies through bolts II, and the lower beam connecting member is connected between the two lower corner assemblies through bolts III.

[0007] The pressure equalizing ring also includes at least one left column connecting member and at least one right column connecting member, wherein the left column connecting member is connected between the upper corner assembly and the lower corner assembly on the left side by bolt IV, and the right column connecting member is connected between the upper corner assembly and the lower corner assembly on the right side by bolt V.

[0008] A ladder is provided on the inner side of the U-shaped frame.

[0009] The advantages and positive effects of the present invention are as follows: by adopting a structure combining a U-shaped frame and a rectangular frame, the U-shaped distributed oil cylinder force can be evenly output to the rectangular jacking pipe section through the rectangular frame, ensuring that the pipe section is subjected to uniform jacking force during the rectangular jacking construction process. It can effectively prevent the pipe section from deviating from the preset axis, and reduce the risk of damage and cracking of the pipe section due to uneven force. At the same time, the geometric dimensions of the pressure equalizing ring can be adjusted through the connector as needed, and the utilization rate is relatively high. In summary, the present invention can not only improve the accuracy and efficiency of construction, but also ensure the integrity of the pipe section and the overall quality of the project.

[0014] In order to further understand the content, features and effects of the present invention, the following embodiments are given as examples and described in detail with reference to the accompanying drawings:

[0015] See also Figures 1 to 3 , an adjustable equalizing pressure ring for rectangular pipe jacking construction, including a U-shaped frame and a rectangular frame, the U-shaped frame is arranged face to face with the jacking cylinder, the rectangular frame is arranged face to face with the jacking pipe section, and the U-shaped frame and the rectangular frame are fitted and fixed together.

[0016] The more preferred solution of this embodiment is as follows:

[0017] The pressure equalizing ring is formed by connecting components by bolts, wherein the components include two upper corner components 1 and two lower corner components 2, which are convenient for transportation and installation.

[0018] The pressure-equalizing ring also includes at least one upper beam connector 3 and at least one lower beam connector 4. The upper beam connector 3 is connected between the two upper corner assemblies 1 via bolts II, and the lower beam connector 4 is connected between the two lower corner assemblies 2 via bolts III. The lateral dimensions of the pressure-equalizing ring can be varied by connecting the upper and lower beam connectors 3 and 4. The dimensions and number of the upper and lower beam connectors 3 and 4 are determined based on the lateral dimensions of the rectangular tube segment.

[0019] Similarly, the pressure-equalizing ring also includes at least one left column connector and at least one right column connector, not shown in the figure. The left column connector is connected between the upper corner assembly and the lower corner assembly on the left side via bolt IV, and the right column connector is connected between the upper corner assembly and the lower corner assembly on the right side via bolt V. By connecting the left and right column connectors, the vertical dimensions of the pressure-equalizing ring can be changed. The size and number of the left and right column connectors are determined by the vertical dimensions of the rectangular pipe segment.

[0020] A ladder 5 is provided on the inner side of the U-shaped frame to facilitate construction.

[0021] The working principle of this utility model:

[0022] When in use, the pressure-equalizing ring is placed between the oil cylinder and the pipe section. The oil cylinder's jacking force acts directly on the U-shaped frame, which is then transmitted to the pipe section through the rectangular frame attached and fixed to it. The U-shaped distributed force is evenly converted into a rectangle through the rectangular frame and output to the rectangular pipe section, so that the rectangular pipe section is subjected to a uniformly distributed force. At the same time, by adopting a bolt connection assembly and setting up upper and lower beam connectors and left and right column connectors, different sizes of connectors can be installed according to the size of the pressure-equalizing ring. The size of the pressure-equalizing ring can be adjusted through the connectors to meet the construction needs of pipes of different sizes and improve utilization.

[0023] Although the preferred embodiments of the present invention have been described above in conjunction with the accompanying drawings, the present invention is not limited to the above-mentioned specific embodiments. The above-mentioned specific embodiments are merely illustrative and not restrictive.
