[0044] Please refer to the attached document. Figures 1-4 This application illustrates a large-section tunnel-excavated station side, top, and arch reinforcement binding trolley provided in an embodiment of the present application. It is used for binding the side, top, and arch reinforcement of tunnel-excavated stations and ensures that the relevant equipment can be transported within the station tunnel. Specifically, it includes: a double-layer frame 1, a walking support system 3, a telescopic side support assembly 2, and an extended platform 4.

[0045] The middle of the first layer of the double-layer frame 1 forms a passage area to ensure that the relevant equipment can be transported and used in the station tunnel. The bottom of the double-layer frame 1 is equipped with a walking support system 3, which allows the double-layer frame 1 to move along the length of the tunnel of the mined station. The length of the double-layer frame 1 is generally designed to be about 9m. It completes the work along the entire length of the tunnel by moving. Both ends of the double-layer frame 1 along the length of the tunnel are fixedly installed with extension platforms 4, which can meet the requirement of binding 9 meters of steel bars and waterproof boards each time, and provide sufficient space for integrated steel bar binding operations. Both sides of the double-layer frame 1 are equipped with retractable side support components 2. When the double-layer frame 1 is in use (when the double-layer frame 1 is fixed), the side support components 2 extend and support the side of the tunnel, forming a stable support for the double-layer frame 1, making the double-layer frame 1 more stable during operation.

[0046] This utility model designs a double-layer frame 1, with a passage area formed in the middle of the first layer of the double-layer frame 1 to ensure that the relevant equipment can be transported and used in the station tunnel. Furthermore, the double-layer frame 1 is designed with retractable side support components 2 on both sides. When the double-layer frame 1 is in use, the side support components 2 extend and support the side of the tunnel to form a stable support for the double-layer frame 1, making the double-layer frame 1 more stable during operation.

[0047] In one embodiment, the side support assembly 2 includes: a plurality of fixed rods 201, telescopic rods 202, retaining sleeves 203, square flanges 204, push frames 205, diagonal connecting rods 206, wire ropes 208, and hydraulic telescopic components 2010 that are fixedly connected to the side of the double-layer frame 1 and distributed parallel to each other.

[0048] The fixed rod 201 is fixedly connected to the side of the double-layer frame 1. Multiple fixed rods 201 are provided, arranged parallel to each other. A square flange 204 is fixedly connected to the end of each fixed rod 201. A telescopic rod 202 is slidably installed at the end of each fixed rod 201. The telescopic rod 202 and the fixed rod 201 form a telescopic structure. A retaining sleeve 203 is fixedly installed on the side of the telescopic rod 202 by screws. The screws are threadedly connected to the retaining sleeve 203. The retaining sleeve 203 can... The position is adjusted by sliding on the fixed rod 201, and the retaining sleeve 203 is fixedly connected to the fixed rod 201 using screws; the push frame 205 is perpendicular to the telescopic rod 202, and one side of the push frame 205 is connected to the double-layer frame 1 through the diagonal connecting rod 206. The push frame 205 is located between the square flange 204 and the retaining sleeve 203. A pull-back steel wire 2011 is connected between the push frame 205 and the retaining sleeve 203. When the push frame 205 moves backward, it can pull the pull-back steel wire 2011, thereby causing the retaining sleeve 203 to move backward. 3. The telescopic rod 202 retracts towards the fixed rod 201, and the wire rope 208 slides through the inclined connecting rod 206. A ball joint 209 is fixedly connected to the wire rope 208 near the inclined connecting rod 206. The hydraulic telescopic component 2010 is fixedly installed on the outermost fixed rod 201, and the wire rope 208 is fixedly connected to the telescopic end of the hydraulic telescopic component 2010. When the hydraulic telescopic component 2010 extends, it pushes one end of the wire rope 208 to move, and the ball joint 209 on the wire rope 208 locks in place. On the side of the inclined connecting rod 206, the inclined connecting rod 206 is rotated, causing the pusher 205 to move outward. The pusher 205 pushes the retaining sleeve 203 to move outward, causing the retaining sleeve 203 and the telescopic rod 202 to slide outward, so that the end of the telescopic rod 202 abuts against the inner wall of the tunnel. A spring assembly 207 is connected between the pusher 205 and the double-layer frame 1. The spring assembly 207 gives the pusher 205 the function of elastic return. When returning, the pusher 205 abuts against the side of the square flange 204.

[0049] In one embodiment, the side support component 2 is provided with multiple layers. The multi-layer structure provides more stable support and ensures the stability of the double-layer frame 1 during use.

[0050] In one embodiment, the double-layer frame 1 includes: two sets of first-layer support systems 101 in an inverted triangular shape located on both sides of the tunnel, a first-layer platform 102, a second-layer column support system 104 fixedly installed on the top of the first-layer platform 102, a second-layer platform 105, a second-layer inclined frame support system 108, and a transverse connection system 109.

[0051] A platform 102 is fixedly installed on the top of two sets of first-layer support systems 101. A passage area is formed between the bottom of the first-layer platform 102 and the two sets of first-layer support systems 101. A first ladder 103 is installed on the side of the first-layer support system 101, which allows construction workers to climb onto the first-layer platform 102. A second-layer platform 105 is fixedly installed on the top of the second-layer column support system 104. An auxiliary platform 107 is fixedly installed on the top of the second-layer platform 105. A second ladder 106 is installed between the first-layer platform 102 and the second-layer platform 105, which allows construction workers to climb onto the second-layer platform 105. A second-layer inclined frame support system 108 is also installed between the first-layer platform 102 and the second-layer platform 105 to further increase the stability of the second-layer platform 105. A transverse connecting system 109 is set longitudinally in the first-layer support system 101, which connects the two-layer frame 1 laterally.

[0052] In one embodiment, the walking support system 3 includes: a walking wheel 301 fixedly installed at the bottom of the double-layer frame 1, a power trolley 303 hingedly installed at the bottom of the double-layer frame 1, and several sets of telescopic support systems 302 fixedly installed at the bottom of the double-layer frame 1 and located between the walking wheel 301 and the power trolley 303. The walking wheel 301 and the power trolley 303 are distributed at both ends of the bottom of the double-layer frame 1.

[0053] When moving, several sets of telescopic support systems 302 retract upwards, and the traveling wheels 301 and the power trolley 303 support the double-layer frame 1. The power trolley 303 provides power to move the double-layer frame 1. During construction, several sets of telescopic support systems 302 extend downwards and stably support the track, thus maintaining the stability of the double-layer frame 1.

[0054] In one embodiment, the powered vehicle 303 includes: a vehicle body 3031, track wheels 3033, a motor 3034, and a reducer 3035.

[0055] The car body 3031 is equipped with a track wheel 3033. The top of the car body 3031 is fixedly connected to a connecting ear 3032, which is hinged to the bottom of the double-layer frame 1. The motor 3034 and the reducer 3035 are both fixedly installed on the car body 3031. The output end of the motor 3034 is connected to the input end of the reducer 3035, and the output end of the reducer 3035 is connected to the shaft of the track wheel 3033.

[0056] When in operation, the motor 3034 drives the reducer 3035, which in turn drives the track wheel 3033 to rotate, and the track wheel 3033 moves on the track.
