[0002] The subway tunnel track area is the core area for train operation, mainly including the track lines, overhead contact system, communication and signaling equipment, and drainage ditches and other ancillary facilities, providing basic support and power guarantee for train operation. After the tunnel construction is completed and the tracks are laid, a large amount of construction work is required in the tunnel track area, including decoration, electromechanical installation, and sealing of manholes.

[0003] When carrying out construction or maintenance in the track area, scaffolding is often required. Traditional scaffolding consists of a support body, with rollers installed at the bottom of the support body to contact the track and move along it. The upper part of the support body is equipped with a construction platform for workers to stand and ensure safety.

[0022] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention.

[0023] Please see Figure 1 One embodiment of the construction support for the subway tunnel track area includes a support body 10 and a chassis 20, wherein the chassis 20 is used to support the track 1, and the support body 10 is in contact with the tunnel wall 2 to achieve stable arrangement of the construction support.

[0024] Please refer to the following: Figure 2 The support body 10 has a construction platform 11, which is used to support construction personnel for construction operations. The support body 10 is equipped with support rollers 12 that contact the tunnel wall 2. The contact between the support rollers 12 and the tunnel wall 2 provides support for the entire construction support.

[0025] Please refer to the following: Figure 3 The chassis 20 includes a base 21 hinged to the support body 10, and a first roller 22 and a second roller 23 mounted on the base 21. The chassis 20 also includes a telescopic member 24 mounted on the base 21 and a third roller 25 mounted on the telescopic member 24. The first roller 22 is used to contact the top surface of the track 1, the second roller 23 and the third roller 25 are respectively used to contact the two sides of the track 1, and the telescopic member 24 is used to drive the third roller 25 to abut against or move away from the side of the track 1.

[0026] When using the aforementioned construction support for the subway tunnel track area, the telescopic component 24 retracts, causing the third roller 25 to move, ensuring the distance between the third roller 25 and the second roller 23 is greater than the width of the track 1. Then, the base 21 is placed over the track 1. The first roller 22 contacts the top surface of the track 1, and the second roller 23 contacts the side surface of the track 1. Next, the telescopic component 24 drives the third roller 25 to move towards the track 1, contacting the other side of the track 1. The first roller 22, the second roller 23, and the third roller 25 are fixed to the track 1 at three points, ensuring the stability of the construction support.

[0027] In one embodiment, the base 21 has a U-shaped structure and includes a top plate 211 and a first side plate 212 and a second side plate 213 mounted on opposite sides of the top plate 211. The top plate 211 is hinged to the support body 10. A first roller 22 is mounted on the top plate 211, a second roller 23 is mounted on the first side plate 212, and a telescopic member 24 is mounted on the second side plate 213. The base 21 has openings on both sides to allow operators to easily observe the telescopic member 24, the first roller 22, the second roller 23, and the third roller 25.

[0028] In one embodiment, a support 214 is provided on the base 21, and the support 214 has a mounting groove. The telescopic member 24 is detachably installed in the mounting groove of the support 214. Specifically, the support 214 is arranged on the second side plate 213 of the base 21, and the telescopic member 24 is engaged in the mounting groove of the support 214, which facilitates the maintenance and replacement of the telescopic member 24. In one embodiment, the telescopic member 24 is a jack. It is understood that in other embodiments, the telescopic member 24 may also be other components capable of telescopic movement, such as a hydraulic cylinder, a pneumatic cylinder, or an electric telescopic rod.

[0029] Please see Figure 2 In one embodiment, the support body 10 includes a deformable frame structure, which deforms to maintain the level of the construction platform 11. When the tunnel specifications differ, the support rollers 12 of the support body 10 need to contact the tunnel wall 2, causing the support body 10 to tilt to varying degrees. This may result in the construction platform 11 also being tilted, making it difficult for construction workers to maintain their footing. Additionally, tools on the construction platform 11 are prone to falling, posing a threat to the personal safety of the construction workers. Therefore, the deformation of the deformable frame structure is used to maintain the level of the construction platform 11, ensuring the safety of the construction workers.

[0030] In one embodiment, the deformable frame structure includes a parallelogram frame 13 and a deformable telescopic member 14 for driving the deformation of the parallelogram frame 13. The construction platform 11 is located on the top edge of the parallelogram frame 13. The deformation telescopic member 14 drives the deformation of the parallelogram frame 13 to ensure that the top edge of the parallelogram frame 13 is in a horizontal state, thereby ensuring that the construction platform 11 is also in a horizontal state.

[0031] Specifically, the parallelogram frame 13 includes a first vertical rod 131, a horizontal beam 132, a second vertical rod 133, and a support rod 134 arranged sequentially along the circumferential direction. The first vertical rod 131, the horizontal beam 132, the second vertical rod 133, and the support rod 134 are hinged sequentially to form a parallelogram structure. The two ends of the deformable telescopic member 14 are hinged to the first vertical rod 131 and the horizontal beam 132, respectively. The extension and retraction of the deformable telescopic member 14 can drive the relative rotation of the first vertical rod 131 and the horizontal beam 132, thereby realizing the deformation of the parallelogram frame 13. The first vertical rod 131 is hinged to the base 21, connecting the support body 10 to the base 21. The construction platform 11 is set on the horizontal beam 132.

[0032] Please refer to the following: Figure 4 In one embodiment, the deformable frame structure is provided in two sets at intervals. The first vertical bars 131 of the two sets of deformable frames are connected by multiple sets of connecting rods 135, thereby connecting the two sets of deformable frame structures into a whole. At the same time, the multiple sets of connecting rods 135 also constitute the ladder of the construction support for construction personnel to go up and down the construction platform 11.

[0033] In one embodiment, a tilt sensor 15 is provided on the crossbeam 132. The tilt sensor 15 is used to detect the angle of the crossbeam 132. When the crossbeam 132 is tilted, it indicates that the construction platform 11 is also tilted. At this time, the deformable telescopic member 14 extends and retracts, driving the parallelogram frame 13 to deform until the crossbeam 132 is in a horizontal state. Safety railings 16 are provided around the construction platform 11 to protect the construction personnel on the construction platform 11 and ensure their safety.

[0034] The specific method for using the aforementioned construction scaffolding in the subway tunnel track area is as follows: The telescopic component 24 retracts, causing the third roller 25 to move away from the second roller 23, so that the distance between the third roller 25 and the second roller 23 is greater than the width of the track 1. Then, the base 21 is placed on the track 1, so that the first roller 22 contacts the top surface of the track 1 and the second roller 23 contacts the side surface of the track 1, supporting the main frame's support rollers 12 against the tunnel wall 2, thus achieving initial stability of the construction support.

[0035] Next, the telescopic component 24 drives the third roller 25 to move towards the track 1 and contact the other side of the track 1. The first roller 22, the second roller 23, and the third roller 25 are engaged at three points and fixed on the track 1, thus fixing the construction support. During the use of the construction support, when the tilt sensor 15 detects that the crossbeam 132 is tilted, the deformable telescopic component 14 extends and retracts, driving the parallelogram frame 13 to deform until the crossbeam 132 is in a horizontal state.

[0036] The aforementioned construction support system for the subway tunnel track area has its first roller 22, second roller 23, and third roller 25 engaged and fixed to the track 1 at three points, ensuring the stability of the support system and preventing it from swaying or overturning, thus guaranteeing the safety of construction personnel. The deformable frame structure also allows the construction platform 11 to remain level, further ensuring the safety of construction workers.

[0037] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model, and they should all be covered within the scope of the claims and specification of this utility model.
