Description

Technical Field

[0001] This utility model relates to the field of urban rail transit construction equipment technology, specifically to a track adjustment-assisted inclined support device. Background Technology

[0002] Urban rail transit is a public transportation system that uses dedicated tracks for guidance and primarily serves commuting needs. It forms the backbone of urban public transportation and is characterized by energy efficiency, land conservation, large capacity, all-weather operation, low or no pollution, and safety, making it a green and environmentally friendly transportation system.

[0003] In subway track construction, due to delays in platform slab construction, the track panel support system uses steel reinforcement heads embedded in the base plate as connection points for lateral and diagonal supports. These rigid anchor points resist multidimensional loads generated by concrete pouring, equipment vibration, and the track panel's own weight, ensuring the track panel maintains its designed position and geometric accuracy before the concrete hardens. However, this method suffers from unreliable lateral and diagonal support reinforcement, affecting the accuracy of track panel erection. Furthermore, each support requires individual reinforcement, resulting in significant steel consumption. Utility Model Content

The other end of the first threaded rod is hinged to the second connecting device by bolts, and the other end of the second threaded rod is hinged to the lateral support base by bolts.

[0007] Furthermore, the lateral support base includes a base plate, a first base side plate, and a second base side plate. The first base side plate and the second base side plate are parallel and spaced apart on the base plate. One end of the second threaded rod is located between the first base side plate and the second base side plate, and the second threaded rod is connected to the first base side plate and the second base side plate by bolts. Bolt holes for fixing the base plate are provided on the base plate.

[0008] Furthermore, the transverse support device includes a third threaded rod, a fourth threaded rod, and a transverse support rod.

[0037] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. The following description of at least one exemplary embodiment is merely illustrative and is in no way intended to limit the present utility model or its application or use. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model.

[0038] like Figures 1 to 4As shown, this utility model embodiment provides a track-adjustable assisted inclined support device, including a support structure 1, a connecting device 2, and an adjusting device 3. The support structure 1 includes a column 11, a fixed base 12, and a limiting plate 13. One end of the column 11 is fixedly connected to the fixed base 12, and the other end of the column 11 is fixedly connected to the limiting plate 13. The fixed base 12 has bolt holes for fixing the fixed base 12. The connecting device 2 includes a first connecting device 21, a second connecting device 22, and a third connecting device 23. The first connecting device 21 is fixedly installed on the top of the column 11 and is located below the limiting plate 13. The adjusting device 3 includes a lateral support base 6, a length-adjustable lateral support device 4, and a length-adjustable transverse support device 5. One end of the lateral support device 4 is hinged to the lateral support base 6, and the other end of the lateral support device 4 is hinged to the second connecting device 22. One end of the transverse support device 5 is hinged to the third connecting device 23.

[0039] In this embodiment, the column 11 installed on the fixed base 12 serves as the main support structure. The fixed base 12 is detachably fixed to the working surface by bolts, realizing the reuse of the device and avoiding the problem of large steel consumption caused by the need for separate rebar installation at each support in traditional construction methods. This provides a stable support foundation for track adjustment. The connecting device 2 provides a connection point for the column 11, the transverse support device 4, and the lateral support device 5, improving the stability of the device.

[0040] like Figure 2 As shown, the lateral support device 4 includes a first threaded rod 41, a second threaded rod 42, and a lateral support rod 43. The threads of the first threaded rod 41 and the second threaded rod 42 have opposite directions. One end of the lateral support rod 43 has a first threaded hole along the axial direction, and the other end of the lateral support rod 43 has a second threaded hole along the axial direction. One end of the first threaded rod 41 is threadedly connected to the first threaded hole, and one end of the second threaded rod 42 is threadedly connected to the second threaded hole. The other end of the first threaded rod 41 is hinged to the second connecting device 22 by bolts, and the other end of the second threaded rod 42 is hinged to the lateral support base 6 by bolts. The lateral support device 4, through its combination of rotatable connection and adjustable length design, allows it to adapt to different installation requirements at different distances and angles between the base plate and the rail panel, improving the versatility and flexibility of the device. It directly resists lateral forces, providing a stable triangular support structure for the entire device, greatly enhancing the overall structural rigidity and anti-overturning capability.

[0041] In this embodiment, the lateral support base 6 includes a base plate 61, a first base side plate 62, and a second base side plate 63. The first base side plate 62 and the second base side plate 63 are parallel and spaced apart on the base plate 61. One end of the second threaded rod 42 is located between the first base side plate 62 and the second base side plate 63, and the second threaded rod 42 is connected to the first base side plate 62 and the second base side plate 63 by bolts. The base plate 61 has bolt holes for fixing the base plate 61. The lateral support base 6 is fixed by bolts, which provides a larger and more stable connection surface and pull-out and shear resistance compared to a single inserted rebar head. The bolt connection method allows for easy disassembly and transfer to the next support point, greatly saving rebar consumption and significantly reducing material costs and the time cost of the rebar installation process.

[0042] like Figure 2 As shown, the lateral support device 5 includes a third threaded rod 51, a fourth threaded rod 52, and a lateral support rod 53. The threads of the third threaded rod 51 and the fourth threaded rod 52 have opposite directions. One end of the lateral support rod 53 has a third threaded hole along the axial direction, and the other end of the lateral support rod 53 has a fourth threaded hole along the axial direction. One end of the third threaded rod 51 is threadedly connected to the third threaded hole, and one end of the fourth threaded rod 52 is threadedly connected to the fourth threaded hole. The other end of the third threaded rod 51 is hinged to the third connecting device 23. The lateral support device 5 utilizes the structure of a bidirectional reverse threaded rod and a support rod, with one end fixedly connected to the connecting device 2, to provide lateral thrust or tension, directly adjusting and fixing the horizontal position of the track.

[0043] like Figure 1 As shown, the track adjustment assist type inclined support device also includes a fixed top block 7, which is fixedly connected to the other end of the fourth threaded rod 52. The fixed top block 7 is used to contact the rail and transmit force. In this embodiment, the fixed top block 7 includes a first side plate 71, a second side plate 72, and a third side plate 73. The first side plate 71 and the third side plate 73 are arranged opposite to each other. The opposite two side edges of the second side plate 72 are fixedly connected to the first side plate 71 and the third side plate 73, respectively. The first side plate 71 has a through first bolt hole along its thickness direction, and the third side plate 73 has a through second bolt hole along its thickness direction. The fixed top block 7 and the fourth threaded rod 52 are fixedly connected by bolts passing through the first bolt hole and the second bolt hole. The fixed top block 7 directly and effectively transmits the lateral thrust or tension generated by the lateral support device to the side of the rail. The increased contact surface and the close-fitting design ensure that the adjustment force is accurately and stably applied to the target position of the rail, avoiding slippage or deviation, effectively preventing hard damage to the rail surface during the adjustment process, and ensuring the quality of the track.

[0044] like Figure 4As shown, the first connecting device 21 is a prism structure, which is a quadrangular prism formed by four side walls, with both the upper and lower ends of the prism being open. The second connecting device 22 has the same structure as the fixed top block 7, and the third connecting device 23 has the same structure as the fixed top block 7. In this embodiment, the vertical height of the first connecting device 21 is greater than the vertical height of the third connecting device 23, allowing the connection position of the third connecting device 23 to be adjusted vertically, thus improving the applicability of the device. The first connecting device 21, the second connecting device 22, and the third connecting device 23 provide connection areas for the columns, horizontal support devices, and lateral support devices that need to be connected. The splicing method simplifies the construction process, and with the cooperation of the limiting plate 13, it lays the foundation for the adjustable angle of the lateral support device.

[0045] In this embodiment, a first assist through hole 81 is radially formed on the lateral support rod 43, and a second assist through hole 82 is radially formed on the transverse support rod 53. An auxiliary tool can be inserted into the first assist through hole 81 or the second assist through hole 82 to rotate the corresponding lateral support rod 43 or transverse support rod 53, thereby adjusting the length of the corresponding lateral support device 4 or transverse support device 5. The assist through holes, through the application of the lever principle, allow workers to complete operations requiring large torque with relatively small force, greatly reducing labor intensity and improving operational efficiency.

[0046] like Figure 1 As shown, the support structure 1 also includes reinforcing ribs 14. There are multiple reinforcing ribs 14, which are fixedly installed at the connection between the column 11 and the fixed base 12. The multiple reinforcing ribs 14 are distributed circumferentially around the column 11.

[0047] In this embodiment, the working process of the track adjustment-assisted inclined support device is as follows:

[0048] Step 1, such as Figure 1 As shown, within the extension range of the transverse support device 5, the support structure 1 is fixed to the working bottom surface with bolts via the fixed support 12, and the first connecting device 21 is fixed to the area near the top of the column 11.

[0049] Step 2, as follows Figure 2 and Figure 5 As shown, the upper part of the lateral support device 4 and the tail of the transverse support device 5 are connected to the top of the column 11 by the second connecting device 22 and the third connecting device 23. By rotating the transverse support rod 53 to extend the axial preload generated in the state of the transverse support device 5, the transverse support device 5 is fixed between the top of the column and the rail. The lateral support base 6 is fixed within the extension range of the lateral support device 4, and the inclined support is provided for the entire device under the action of the limiting plate 13.

[0050] Step 3, as follows Figure 5 and Figure 6 After the connection is completed, the lateral support device 4 and the transverse support device 5 resist the lateral pressure and buoyancy generated on the track panel during concrete pouring, transform the dynamic construction load into the shear resistance of the base plate structure, prevent the track panel from shifting or overturning, and control the geometric dimensions of the track panel during the pouring process.

[0051] In the description of this utility model, it should be understood that the orientation or positional relationship indicated by directional terms such as "upper" and "lower" and "top" and "bottom" is usually based on the orientation or positional relationship shown in the accompanying drawings, and is only for the convenience of describing this utility model and simplifying the description. Unless otherwise stated, these directional terms do not indicate or imply that the device or element referred to must have a specific orientation or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation on the scope of protection of this utility model; the directional terms "inner" and "outer" refer to the inner and outer contours relative to the outline of each component itself.

[0052] Furthermore, it should be noted that the use of terms such as "first" and "second" to define components is merely for the purpose of distinguishing the corresponding components. Unless otherwise stated, the above terms have no special meaning and therefore cannot be construed as limiting the scope of protection of this utility model.

[0053] The above description is merely a preferred embodiment of the present utility model and does not constitute any limitation on the present utility model. Any simple modifications, alterations, or equivalent structural transformations made to the above embodiments based on the technical essence of the present utility model shall still fall within the protection scope of the present utility model.
