Description

Technical Field

[0001] This utility model relates to the field of railway catenary technology, specifically to a catenary counterweight foundation structure. Background Technology

[0002] The overhead contact line support is the "backbone" of high-speed railways and urban rail transit, responsible for supporting the entire overhead contact line system and ensuring that electric locomotives or EMUs can obtain power stably and safely. The overhead contact line foundation provides an absolutely solid and immovable "base" for the overhead contact line support. The overhead contact line foundation is the underground and invisible part of the entire overhead contact line system, but it is crucial and directly determines the stability and safety of the superstructure.

[0003] Goaf areas, also known as "mining subsidence areas" or "old goaf areas," specifically refer to the cavities left after underground mineral resources (such as coal, metal mines, gypsum, etc.) have been mined out, as well as the areas affected by these cavities in the overlying rock strata. The underground rock strata in goaf areas will continuously collapse and compact, resulting in continuous and uneven surface subsidence, which may last for years or even decades. This subsidence is completely unpredictable. When contact wire support pillars are erected in geologically unstable goaf areas, the contact wire support pillars will sink or tilt in a short period of time. Traditional contact wire foundations are difficult to adjust later. If contact wire support pillars are re-erected, it will result in engineering waste, high costs, inconvenient construction, and affect train operation.

[0004] Therefore, there is an urgent need for a catenary counterweight foundation structure that is easy to adjust later, simple to construct, and low in cost. Summary of the Invention

[0005] The purpose of this invention is to provide a catenary counterweight foundation structure to at least solve the problems of traditional catenary foundations, such as inconvenience in later adjustment, complex construction, and high cost.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0007] A catenary counterweight foundation structure includes multiple counterweight modules, a foundation body, and support columns;

[0008] The bottom of the foundation body is shallowly buried below the ground, and the top of the foundation body is above the ground;

[0009] The counterweight modules are spaced apart and detachably mounted on the top of the base body, and the support columns are detachably mounted on the top of the base body.

[0010] Furthermore, the counterweight module is made of solid iron and is in the shape of a cuboid.

[0011] Furthermore, the counterweight module is fixed to the base body via a disassembly assembly.

[0012] Furthermore, the disassembly assembly includes a fixing clamp and several bolts. The fixing clamp is disposed on the surface of the counterweight module and fixed to the base body by the bolts.

[0013] Furthermore, the fixing clamp includes a curved portion and multiple horizontal portions. The horizontal portions are respectively disposed on both sides of the bottom of the curved portion. The curved portion is in close contact with the surface of the counterweight module, and the horizontal portions are in close contact with the top of the base body. The bolts are respectively fixed to the horizontal portions.

[0014] Furthermore, the cross-section of the curved portion is rectangular.

[0015] Furthermore, the support column is fixed to one side of the counterweight module by several fasteners.

[0016] Furthermore, the fastener is a fastening bolt.

[0017] Furthermore, the support column is selected as a lattice steel column.

[0018] Furthermore, the main body of the foundation is made of steel.

[0019] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0020] This utility model provides a catenary counterweight foundation structure, which includes a counterweight module, a foundation body, and supports. The counterweight module is fixed to the foundation body with bolts, and the supports are fixed to the foundation body with fastening bolts. The counterweight module and supports can be disassembled and installed using only bolts and fastening bolts. The construction is simple, the subsequent adjustment is convenient, the project cost is low, and it is easy to operate and maintain.

[0030] Example:

[0031] like Figure 1 As shown, this embodiment provides a catenary counterweight foundation structure, including three counterweight modules 1, a foundation body 2, and a support column 3. It is simple to construct, easy to adjust, and convenient for operation and maintenance.

[0032] Specifically, the bottom of the foundation body 2 is shallowly buried below the ground, and the top of the foundation body 2 is above the ground. The counterweight modules 1 are spaced apart and detachably installed on the top of the foundation body 2, and the support columns 3 are detachably installed on the top of the foundation body 2. Both the counterweight modules 1 and the support columns 3 are detachable, which facilitates disassembly and subsequent adjustment.

[0033] In this embodiment, the counterweight module 1 is made of solid iron block and is rectangular in shape. The three counterweight modules 1 are equidistantly arranged on one side of the base body 2.

[0034] Specifically, the counterweight module 1 is fixed to the foundation body 2 through disassembly components. The counterweight module 1 is used to balance the bending moment generated by the support column 3.

[0035] The disassembly assembly includes a fixing clamp 5 and several bolts. The fixing clamp 5 is tightly attached to the top surface and two sides of the counterweight module 1 and the top surface of the base body 2. The fixing clamp 5 is fixed to the base body 2 by bolts. The fixing clamp 5 wraps around the counterweight module 1 and is fixed to the base body 2, thereby fixing the counterweight module 1 to the base body 2.

[0036] In this embodiment, as Figure 3 As shown, the fixing clamp 5 includes a curved part 51 and two horizontal parts 52. The horizontal parts 52 are integrally disposed on both sides of the bottom of the curved part 51. The curved part 51 is in close contact with the top surface and two sides of the counterweight module 1. The horizontal parts 52 are in close contact with the top surface of the base body 2 on both sides of the counterweight module 1. Bolts pass through the horizontal parts 52 and are fixed to the base body 2, thereby fixing the fixing clamp 5 to the base body 2.

[0037] In this embodiment, the cross-section of the bent portion 51 is rectangular, which is consistent with the cross-section of the counterweight module 1.

[0038] Specifically, such as Figure 2 As shown, the support column 3 is fixed to one side of the counterweight module 1 by several fasteners and is aligned with the counterweight module 1 located in the middle.

[0039] In this embodiment, the fastener is a fastening bolt 4, which is distributed on both sides of the bottom of the support column 3. The fastening bolt 4 penetrates the bottom of the support column 3, thereby fixing the support column 3 to the foundation body 2.

[0040] In this embodiment, the support column 3 is a lattice steel column.

[0041] In this embodiment, the foundation body 2 is made of steel structure, and the bottom of the foundation body 2 is made of steel plate to increase the load-bearing area.

[0042] In this embodiment, if the support column 3 sinks or tilts due to ground subsidence, the bolts at the bottom of the counterweight module 1 and the fastening bolts 4 at the bottom of the support column 3 are removed, the support column 3 and the counterweight module 1 are dismantled, the foundation body 2 is leveled, and the support column 3 and the counterweight module 1 are reinstalled after the foundation body 2 is leveled.

[0043] In this embodiment, the counterweight module 1 and the support column 3 can be disassembled and installed using only bolts and fastening bolts 4. The construction is simple, the subsequent adjustment is convenient, the project cost is low, and the operation and maintenance are convenient.

[0044] The above-described specific examples are for illustrative purposes only and are not intended to limit the scope of this invention. Those skilled in the art to which this invention pertains can make various simple deductions, modifications, or substitutions based on the concept of this invention.
