[0040] In the following description, only certain exemplary embodiments are briefly described. As those skilled in the art will recognize, the described embodiments can be modified in various ways without departing from the spirit or scope of this application. Therefore, the drawings and description are considered to be exemplary in nature and not restrictive.

[0041] See Figures 1-5This invention illustrates a preferred embodiment of an auxiliary work vehicle for installing drainage pipes in a utility tunnel, comprising:

[0042] Work vehicle body 1;

[0043] The front traction wheel 2 is rotatably mounted on the bottom of the working vehicle body 1 and is used to roll in the pipe gallery drainage ditch.

[0044] The rear traction wheel 3 is rotatably mounted on the bottom of the working vehicle body 1. The rear traction wheel 3 and the front traction wheel 2 are arranged sequentially along the front and rear direction of the working vehicle body 1. The rear traction wheel 3 is used to roll in the pipe gallery water collection ditch.

[0045] At least two front guide wheels 4 are rotatably mounted on the bottom of the work vehicle body 1. The two front guide wheels 4 are respectively positioned on the left and right sides of the front traction wheel 2. When the work vehicle body 1 moves along the pipe gallery's water collection ditch, the two front guide wheels 4 roll against the left and right side walls of the pipe gallery's water collection ditch, respectively.

[0046] At least two rear guide wheels 5 are rotatably mounted on the bottom of the work vehicle body 1. The two rear guide wheels 5 are respectively placed on the left and right sides of the rear traction wheel 3. When the work vehicle body 1 moves along the pipe gallery water collection ditch, the two rear guide wheels 5 roll against the left and right side walls of the pipe gallery water collection ditch.

[0047] This utility model discloses an auxiliary work vehicle for installing drainage pipes in integrated utility tunnels. The bottom of the work vehicle body 1 integrates a front traction wheel 2, a rear traction wheel 3, a front guide wheel 4, and a rear guide wheel 5. During installation, the work vehicle body 1 is used to hoist the drainage pipe. The front traction wheel 2 and the rear traction wheel 3 roll within the water collection ditch on the bottom wall of the utility tunnel, providing the main driving force and direction of travel for the work vehicle body 1. The front guide wheel 4 is positioned on the left and right sides of the front traction wheel 2, and during travel, it rests against the left and right side walls of the water collection ditch. Similarly, the rear guide wheel 5 is positioned on the left and right sides of the rear traction wheel 3, and during travel, it rests against the left and right side walls of the water collection ditch. The coordinated operation of the front guide wheel 4 and the rear guide wheel 5 forms a lateral constraint, effectively restricting the lateral deviation of the work vehicle body 1 and fixing its direction of travel. This allows the work vehicle body 1 to maintain a straight line along the water collection ditch, significantly improving stability during movement and thus enhancing the docking accuracy and installation efficiency of the drainage pipe.

[0048] It is understandable that the drainage ditch in the utility tunnel is a channel located in the middle of the bottom wall of the tunnel, parallel to the length of the tunnel. Therefore, during the traction movement, a combination of guide wheels and traction wheels is used. The guide wheels are close to the side wall of the drainage ditch, and the traction wheels provide the power for movement. This not only fixes the direction of movement but also significantly reduces the labor intensity of personnel pushing the work vehicle.

[0049] Specifically, the front guide wheel 4 is rotatably mounted on the front mounting seat of the work vehicle body 1 via a front pivot, while the rear guide wheel 5 is rotatably mounted on the rear mounting seat of the work vehicle body 1 via a rear pivot.

[0050] See Figures 1-2 In one embodiment, the front traction wheel 2, the rear traction wheel 3, the front guide wheel 4, and the rear guide wheel 5 are all located at the bottom center of the work vehicle body 1.

[0051] The auxiliary work vehicle used for installing drainage pipes in integrated utility tunnels also includes:

[0052] Multiple auxiliary wheels 6 are rotatably mounted on the bottom of the work vehicle body 1. The multiple auxiliary wheels 6 are spaced apart. The bottom of the auxiliary wheels 6 is at a higher height than the bottom of the front traction wheel 2 and the rear traction wheel 3. The auxiliary wheels 6 are used to roll on the bottom wall of the pipe gallery to improve the travel stability of the work vehicle body 1, thereby further improving the docking accuracy and installation efficiency of the drainage pipe.

[0053] Specifically, the auxiliary wheel 6 is rotatably mounted on the auxiliary mounting seat of the work vehicle body 1 via an auxiliary pivot.

[0054] To further improve the movement stability and smoothness of the work vehicle body 1, see [reference needed]. Figure 2 In one embodiment, multiple auxiliary wheels 6 are arranged around the front traction wheel 2, the rear traction wheel 3, the front guide wheel 4, and the rear guide wheel 5.

[0055] See Figure 2 In one embodiment, the bottom of the work vehicle body 1 is provided with two rows of auxiliary wheels 6. The two rows of auxiliary wheels 6 are placed on the left and right sides of the front traction wheel 2 and the rear traction wheel 3, respectively. Each row of auxiliary wheels 6 includes multiple auxiliary wheels 6. The multiple auxiliary wheels 6 of each row of auxiliary wheels 6 are arranged at intervals along the front and rear direction of the work vehicle body 1 to improve the overall stability, load uniformity and adaptability of the work vehicle body 1 during travel.

[0056] See Figure 2In one embodiment, at least two front guide wheels 4 are positioned in front of the front traction wheel 2. By positioning at least two front guide wheels 4 in front of the front traction wheel 2, a guiding-then-tractioning travel logic is formed. This allows the front guide wheels 4 to identify and conform to the direction of the drainage ditch in the pipe gallery in advance, pre-adjusting and constraining the travel direction of the work vehicle 1. This effectively reduces the lateral deviation tendency of the front traction wheel 2 and significantly improves the straight-line travel stability and directional control accuracy of the work vehicle 1 within the pipe gallery.

[0057] See Figure 2 In one embodiment, at least two rear guide wheels 5 are arranged behind the rear traction wheel 3. By arranging at least two rear guide wheels 5 behind the rear traction wheel 3, the rear of the work vehicle body 1 continuously receives effective lateral restraint during travel, thereby forming a stable guide surface that runs through the entire length of the work vehicle body 1 in conjunction with the front guide wheel 4. This effectively suppresses the swaying of the rear of the work vehicle body 1 and enhances the anti-sway stability of the work vehicle body 1 in uneven water collection ditches.

[0058] See Figures 1-5 In one embodiment, the auxiliary work vehicle for installing drainage pipes in the integrated utility tunnel further includes:

[0059] Drive assembly 7 is mounted on the work vehicle body 1. The first output end of drive assembly 7 is connected to the front traction wheel 2, which rotates with the first output end. The second output end of drive assembly 7 is connected to the rear traction wheel 3, which also rotates with the second output end. By setting the first and second output ends of drive assembly 7 to independently drive the front traction wheel 2 and the rear traction wheel 3 respectively, a stable synchronous drive structure for the front and rear traction wheels is formed. This effectively enhances the overall traction force of the vehicle, ensuring the synchronous movement and straight-line stability of the work vehicle body 1 within the pipe gallery, thus providing reliable power for the precise alignment and efficient installation of the drainage pipe.

[0060] See Figures 2-4 In one embodiment, the driving component 7 includes:

[0061] Motor 71, motor 71 is mounted on the working vehicle body 1;

[0062] The drive gear 72 is located on the output shaft of the motor 71 and can rotate with the output shaft of the motor 71.

The third driven gear 77 meshes with the first driven gear 74. The third driven gear 77 can rotate with the first driven gear 74. The second driven pulley of the second belt drive mechanism 76 is connected to the front traction wheel 2. The front traction wheel 2 can rotate with the second driven pulley.

[0065] The third belt drive mechanism 78 is movably mounted on the work vehicle body 1. The third driving pulley of the third belt drive mechanism 78 is connected to the fourth driven gear 79. The fourth driven gear 79 meshes with the second driven gear 75. The fourth driven gear 79 can rotate with the second driven gear 75. The third driven pulley of the third belt drive mechanism 78 is connected to the rear traction wheel 3. The rear traction wheel 3 can rotate with the third driven pulley. The drive assembly 7 is driven by a motor 71 driving a drive gear 72, which in turn drives a first driven gear 74 to simultaneously drive a first belt drive mechanism 73 and a second driven gear 75, which in turn drive a third driven gear 77 and a fourth driven gear 79. Finally, the power is transmitted to the front traction wheel 2 through a second belt drive mechanism 76, and to the rear traction wheel 3 through a third belt drive mechanism 78. This forms a compact and forcedly synchronized mechanical transmission chain, which ensures that the speeds of the front traction wheel 2 and the rear traction wheel 3 are strictly consistent, effectively improving the linear stability and power output reliability of the work vehicle 1 in the limited space of the pipe gallery.

[0066] It is understood that the specific installation methods of the aforementioned front traction wheel 2, rear traction wheel 3, drive gear 72, first belt drive mechanism 73, first driven gear 74, second driven pulley, third drive pulley, fourth driven gear 79, second belt drive mechanism 76, and third belt drive mechanism 78 are all common knowledge in the mechanical field. For details, please refer to the prior art, and they will not be elaborated here.

[0067] Specifically, the first driving pulley of the first belt drive mechanism 73 is coaxial with the first driven gear 74 and integrally formed, and the first driven pulley of the first belt drive mechanism 73 is coaxial with the second driven gear 75 and integrally formed.

[0068] Specifically, the second drive pulley of the second belt drive mechanism 76 is coaxial with the third driven gear 77 and is integrally formed.
