Description

Technical Field

[0001] This utility model relates to the field of tunnel construction technology, and in particular to an adjustable shield tunnel section emergency evacuation indicator light bracket. Background Technology

[0002] With the development of urban rail transit, a large number of electromechanical equipment and pipelines need to be installed in the shield tunnel section during the electromechanical equipment installation phase. In order to facilitate the installation of electromechanical equipment and pipelines on the sidewalls of the tunnel section, more and more projects are adopting the segment pre-embedded sliding groove technology to avoid damage to the segment structure caused by drilling during post-anchoring. However, the emergency evacuation indicator lights in the tunnel section are surface-mounted on the shield sidewall, and there are currently no special brackets on the market for installing emergency evacuation indicator lights in shield tunnel sections.

[0003] The conventional approach is to use special T-bolts to fix a channel steel between two sliding grooves and install the emergency evacuation indicator light on the channel steel. This fixing method uses a lot of steel, and the cost of material procurement, processing and transportation is very high, and the construction efficiency is low.

[0004] Therefore, an adjustable emergency evacuation indicator light bracket for shield tunnel sections is needed to solve the above-mentioned technical problems. Utility Model Content

[0005] This utility model addresses the technical problems existing in the prior art by providing an adjustable shield tunnel section emergency evacuation indicator light bracket.

[0006] The technical solution of this utility model to solve the above-mentioned technical problems is as follows: An adjustable shield tunnel section emergency evacuation indicator light bracket includes a connecting plate, a hinge clamp, and a crossbar. The hinge clamp includes a first arc-shaped piece and a second arc-shaped piece, which are rotatably connected. Both the first and second arc-shaped pieces are semi-circular. The lower ends of the first and second arc-shaped pieces each extend with a flat plate extension. A second circular hole is passed through the flat plate extension. A third circular hole is provided at the upper end of the connecting plate. The upper end of the connecting plate is fixed at the second circular hole. Both sides of the crossbar are provided with oval holes. The crossbar is fixed to the connecting plate.

[0007] Preferably, in the above-mentioned adjustable shield tunnel section emergency evacuation indicator light bracket, the connecting plate is provided with a plurality of first circular holes, and the crossbar is provided with a fourth circular hole, wherein the first circular holes and the fourth circular holes are adapted to each other.

[0008] Preferably, in the above-mentioned adjustable shield tunnel section emergency evacuation indicator light bracket, the second circular hole is adapted to the third circular hole, the second circular hole and the third circular hole are penetrated by a first bolt, and the other end of the first bolt is equipped with a first nut.

[0009] Preferably, in the above-mentioned adjustable shield tunnel section emergency evacuation indicator light bracket, each of the two flat plate extensions has a plurality of equidistantly arranged positioning grooves on the side close to each other, and the top two sides of the connecting plate have a plurality of equidistantly arranged protrusions, which are inserted into the positioning grooves, and the protrusions correspond one-to-one with the positioning grooves.

[0010] Preferably, in the above-mentioned adjustable shield tunnel section emergency evacuation indicator light bracket, the inner sides of the first arc-shaped piece and the second arc-shaped piece are both equipped with anti-slip pads.

[0011] Preferably, in the above-mentioned adjustable shield tunnel section emergency evacuation indicator light bracket, the crossbar is provided with two crossbars, both of which are perpendicular to the connecting plate.

[0012] Preferably, in the above-mentioned adjustable shield tunnel section emergency evacuation indicator light bracket, both the second and third circular holes are provided in twos.

[0013] The beneficial effects of this utility model are as follows: This utility model uses a hinge clamp to fix the emergency evacuation indicator light onto the conduit, a connecting plate to be fixed on the hinge clamp, and two crossbars to be fixed on the connecting plate, thus providing an installation carrier for the emergency evacuation indicator light. The lateral fixing spacing of the emergency evacuation indicator light is adjusted by setting oval holes on both sides of the crossbars, and the longitudinal fixing spacing is adjusted by setting multiple first circular holes on the connecting plate. This allows for adjustment according to different sizes of emergency evacuation indicator lights, making it highly versatile. Furthermore, there is no need to fix channel steel between the two sliding grooves, saving material costs. Attached Figure Description

[0019] The principles and features of this utility model are described below with reference to the accompanying drawings. The examples given are only for explaining this utility model and are not intended to limit the scope of this utility model.

[0020] like Figures 1-3 As shown, an adjustable shield tunnel section emergency evacuation indicator light bracket includes a connecting plate 1, a hinge clamp 3, and two crossbars 4, both perpendicular to the connecting plate 1. The hinge clamp 3 includes a first arc-shaped piece 31 and a second arc-shaped piece 32, which are rotatably connected to a rotating shaft 33. Both the first arc-shaped piece 31 and the second arc-shaped piece 32 are semi-circular, and anti-slip pads 34 are installed on their inner sides. The lower ends of both the first arc-shaped piece 31 and the second arc-shaped piece 32 extend into a flat plate extension 35, with a second circular hole passing through the flat plate extension 35. The bracket is fastened to the emergency evacuation indicator light conduit by the first arc-shaped piece 31 and the second arc-shaped piece 32, and locked in place by a first bolt 5 and a first nut 6. A washer 7 is installed between the flat plate extension 35 and the first nut 6 to prevent the bolt from loosening. The anti-slip pad 34 increases friction and prevents the hinge clamp 3 from wobbling.

[0021] The upper end of the connecting plate 1 is provided with a third circular hole. The upper end of the connecting plate 1 is inserted between the two flat plate extensions 35. There are two second and three circular holes, which are adapted to each other. A first bolt 5 is inserted into the second and third circular holes. A first nut 6 is installed on the other end of the first bolt 5. The connecting plate 1 is fixed to the lower end of the hinge clamp 3 by the first bolt 5 and the first nut 6. Furthermore, in order to prevent the connecting plate 1 from shaking after the bolts are slightly loose, multiple equidistant positioning grooves are provided on the side of the two flat plate extensions 35 that are close to each other. Multiple equidistant protrusions are provided on both sides of the top of the connecting plate 1. The protrusions are engaged in the positioning grooves, and the protrusions correspond one-to-one with the positioning grooves, thereby preventing the connecting plate 1 from shaking.

[0022] A crossbar 4 is fixed to a connecting plate 1. The connecting plate 1 has multiple first circular holes 2, and the crossbar 4 has a fourth circular hole. The first circular holes 2 and the fourth circular hole are matched. The first circular holes 2 and the fourth circular hole are connected and fixed by second bolts and second nuts. Two first circular holes 2 are provided in each row, arranged in multiple rows. Two first circular holes 2 are also provided at the bottom of the connecting plate 1. The two bottom first circular holes 2 are used to install and fix one crossbar 4, and the upper first circular holes 2 are used to fix the other crossbar 4. The upper crossbar 4 can be appropriately selected according to the installation height of the emergency evacuation indicator light, and the longitudinal fixing spacing can be adjusted by selecting the first circular holes 2 at different heights. Both sides of the crossbar 4 are provided with oval holes 41 for adjusting the lateral fixing spacing of the emergency evacuation indicator light during installation. The emergency evacuation indicator light is fixedly installed on the four oval holes 41 by bolts and nuts. This utility model can be adjusted and installed according to emergency evacuation indicator lights of different sizes, and has strong versatility.
