Description

Technical Field

[0001] This invention relates to the field of overhead contact system technology for electrified railways, and specifically to an overhead contact system support adjustment device. Background Technology

[0002] The overhead contact system is a high-voltage power transmission line erected along the railway line to supply current to electric locomotives via their pantographs. The verticality of the contact system supports affects the geometric parameters of the contact system, as well as the pantograph-contact relationship and the quality of current collection by the electric locomotives. Frequent subgrade settlement and deformation due to climate change, geological disasters, and human activities cause the contact system supports to tilt, altering the contact system parameters and threatening railway operational safety.

[0003] Currently, overhead contact line supports are mainly fixed to concrete foundations with anchor bolts or directly buried in the roadbed. The disadvantages of this existing technology include: the flange of the upper support is connected to the anchor bolts on the lower foundation, lacking the function of adjusting the support's tilt rate; when roadbed deformation occurs, the support's tilt rate cannot be adjusted; and the support may tilt during installation or in unexpected situations.

[0004] Therefore, there is an urgent need for a device that can adjust the inclination rate of the support and prevent it from tipping over. Summary of the Invention

[0005] The purpose of this invention is to provide a contact wire support adjustment device to at least solve the problems of the inability to adjust the inclination rate of the support when the roadbed deforms and the possibility of the support tilting under installation or accidental circumstances.

[0006] To achieve the above objectives, the technical solution adopted by the present invention is as follows:

[0007] A contact wire support adjustment device includes a base and a spherical structure, wherein the spherical structure is disposed inside the base;

[0008] The base includes an upper base and a lower base, with the lower end of the upper base and the upper end of the lower base positioned opposite each other and in the vertical direction;

[0009] The spherical structure includes an upper column, a sphere, and a lower column, which are integrally formed.

[0010] Furthermore, the upper end of the upper base is connected to the lower end of the support column.

[0011] Furthermore, the lower end of the lower base is connected to the upper end of the base.

[0012] Furthermore, both the lower end of the upper base and the upper end of the lower base are spherical structures.

[0013] Furthermore, both the upper and lower bases are provided with bolt holes.

[0014] Furthermore, the bolt holes are aligned and connected by bolts.

[0015] Furthermore, a first stiffening rib is provided on the upper side of the upper base.

[0016] Furthermore, the lower base is provided with a second stiffening rib and a third stiffening rib on its upper and lower sides, respectively.

[0017] Furthermore, the upper column and the lower column are respectively inserted into the inner cavity of the upper base and the lower base and fit against the inner wall.

[0018] Furthermore, the sphere is attached to the lower end of the upper base and the upper end of the lower base.

[0019] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0020] 1. This invention allows for a significant adjustment of the inclination rate of the support column in any direction by loosening and tightening the bolts connecting the upper and lower bases, thus solving the problem of catenary support column tilting caused by roadbed deformation. This improves catenary parameters, enhances the reliability of the catenary system, reduces the maintenance workload of the catenary system, and saves operating costs.

[0021] 2. The limiting function of the spherical structure can provide anti-overturning bearing capacity when the column tilt rate is too large, avoiding the column from tilting during installation or in case of accidents. Attached Figure Description

[0033] The present invention provides a contact wire support adjustment device.

[0034] Example:

[0035] like Figures 1-4 As shown, a contact wire support adjustment device is disposed between the contact wire support 9 and the foundation 4, and is used to adjust the inclination rate of the support 9.

[0036] The adjustment device includes a base and a spherical structure 1, wherein the spherical structure 1 is disposed inside the base;

[0037] The upper end of the base is connected to the lower end of the support column 9, and the lower end of the base is connected to the foundation 4;

[0038] The base includes an upper base 2 and a lower base 3, with the lower end of the upper base 2 and the upper end of the lower base 3 positioned opposite each other and in the vertical direction.

[0039] The lower part of the upper base 2 is in contact with the spherical structure 1. The inner wall above the spherical surface is cylindrical. It is welded to the support column 9 or fixedly connected by flange or bolt. The lower end of the upper base 2 is provided with bolt holes. The upper side of the upper base 2 is also provided with a first stiffening rib 8.

[0040] The upper inner surface of the lower base 3 is spherical, and the inner wall below the spherical surface is cylindrical. The lower end of the lower base 3 is connected to the foundation 4 by prestressed steel wire, anchor bolts or structural steel bars. The lower base 3 is provided with a second stiffening rib 6 and a third stiffening rib 5 on the upper and lower sides respectively. The lower base 3 is provided with bolt holes at the upper end.

[0041] The bolt holes of the lower base 3 are aligned with the bolt holes of the upper base 2 and connected by bolts 7, so that the upper base 2 and the lower base 3 are connected as one unit.

[0042] Furthermore, the spherical structure 1 includes an upper column, a sphere, and a lower column, which are integrally formed.

[0043] The sphere is in contact with the inner wall of the spherical surface at the lower end of the upper base 2 and the upper end of the lower base 3;

[0044] The lower column is inserted into the inner cavity of the lower base 3 and fits against the inner wall, while the upper column is inserted into the inner cavity of the upper base 2 and fits against the inner wall, thereby achieving a limit and preventing the support column 9 from tipping over.

[0045] If the foundation deformation causes the foundation 4 and support 9 to tilt to the right, loosen the right bolt 7 and tighten the left bolt 7 at the same time. Then the upper base 2 and the support 9 will rotate to the left around the spherical structure 1. When the desired angle is reached, tighten all bolts 7 to complete the angle adjustment.

[0046] Similarly, if the foundation deformation causes the foundation 4 and the support 9 to tilt to the left, loosen the left bolt 7 and tighten the right bolt 7 at the same time. Then the upper base 2 and the support 9 will rotate to the right around the spherical structure 1. When the desired angle is reached, tighten all bolts 7 to complete the angle adjustment.

[0047] The above examples illustrate the present invention only to aid in understanding it and are not intended to limit the scope of the invention. Those skilled in the art can make various simple deductions, modifications, or substitutions based on the ideas of this invention.
