[0030] In order to better understand the purpose, function and specific design of the present invention, the following further describes in detail an intelligent equipment for transporting and installing side leg members of an urban utility tunnel with reference to the accompanying drawings.

[0031] As Figure 1-2 shown, the utility tunnel applied in the present invention is a precast assembled multi-compartment structure of a shield tunnel, including a circular utility tunnel 51. The utility tunnel 51 is connected to the ground through a wellhead. A cast-in-place bottom slab 52 is provided at the bottom of the utility tunnel 51. A continuous flat road surface is formed above the cast-in-place bottom slab 52 for the driving of the chassis assembly 1. Card slots are provided on both sides of the cast-in-place bottom slab 52. The card slots are connected to the side leg members 53. The side leg members 53 are arc-shaped and match the shape of the utility tunnel 51. The lower part of the side leg members 53 is connected to the card slots of the cast-in-place bottom slab 52. The top of the side leg members 53 is in a "T" shape. The top of the side leg members 53 is connected to the horizontal precast slab 54. The horizontal precast slab 54 is a rectangular plate and is placed at the middle position of the utility tunnel, thus forming a double-layer multi-compartment structure of the urban utility tunnel of the present invention.

[0032] As Figure 2-12As shown in the figure, an intelligent device for handling and installing side leg components of an urban utility tunnel includes a chassis assembly 1 for movement. A guiding assembly 2 is provided below the chassis assembly 1 to limit the movement path of the chassis assembly 1. A lifting and grasping assembly 3 is arranged on the chassis assembly 1 for picking up and placing the side leg component 53. The lifting and grasping assembly 3 includes a lifting assembly 31 capable of moving up and down relative to the chassis assembly 1. The top of the lifting assembly 31 is connected to a telescopic grasping assembly 32 which can horizontally telescopically move in the width direction of the chassis assembly 1. A limiting assembly 4 is arranged at the end of the telescopic grasping assembly 32 to limit the position of the side leg component 53 on the telescopic grasping assembly 32, so as to ensure that the telescopic grasping assembly 32 can drive the side leg component 53 to horizontally move relative to the width direction of the chassis assembly 1. There are two groups of lifting and grasping assemblies 3, which are arranged parallel to each other at intervals. The interval distance is greater than the width of the middle part of the side leg component 53 and less than the width of the "T" shape at the top of the side leg component 53, so that the telescopic grasping assembly 32 can grasp the side leg component 53 at the position of the "T" shape at the top.

[0033] Specifically, as Figure 3-5 shown, the lifting assembly 31 includes a lifting bracket 311 fixedly arranged on the upper surface of the chassis assembly 1. A lifting arm 312 is vertically slidably arranged on the lifting bracket 311. The lifting arm 312 is connected to a lifting drive element 313 which can drive the lifting arm 312 to reciprocate vertically. The top of the lifting arm 312 is connected to the telescopic grasping assembly 32 to realize the lifting function of the lifting assembly 31.

[0034] The telescopic grasping assembly 32 includes a telescopic bracket 321 fixedly arranged on the top of the lifting arm 312 of the lifting assembly 31. A telescopic arm 322 is horizontally slidably arranged on the telescopic bracket 321. The telescopic arm 322 is connected to a telescopic drive element 323 which can drive the telescopic arm 322 to reciprocate horizontally to realize the telescopic function of the telescopic grasping assembly 32.

[0035] The lifting drive element 313 and the telescopic drive element 323 can be selected as screw jacks or hydraulic cylinders, etc., as long as they are existing drive elements that can perform heavy-duty reciprocating movement.

[0036] Preferably, in order to improve the stability of the two groups of lifting and grasping assemblies 3, the two groups of lifting and grasping assemblies 3 in this embodiment are connected and fixed by multiple strengthening beams 33.

[0037] As Figure 3-4As shown, the limiting component 4 is detachably arranged on the telescopic arm 322 of the telescopic grasping component 32. The limiting component 4 can adjust the installation position on the lifting arm of the telescopic grasping component 32 according to the size of the side leg member 53 to be transported. In this embodiment, the limiting component 4 is fixed on the telescopic arm 322 of the telescopic grasping component 32 by bolts. The limiting component 4 includes symmetrically arranged limiting blocks. Each limiting block includes an inclined guiding portion 41. The guiding portions 41 of the two limiting blocks form a flared shape that is wider at the top and narrower at the bottom. Below the guiding portion 41 is connected to a limiting portion 42, and the limiting portion 42 is a vertical plane. The limiting portion 42 can be in contact with the front and back surfaces of the side leg member 53 to achieve clamping, thereby fixing the position of the side leg member 53. On the side of the limiting block away from the limiting portion 42, there is an installation portion 43. The installation portion 43 extends away from the limiting block to form a plane, and a plurality of through holes are evenly distributed on the plane to facilitate bolt fixation.

[0038] Preferably, in order to facilitate the picking up of the side leg member 53, in this embodiment, the side leg member 53 is placed on the L-shaped placement rack 7 by a crane. When picking up the side leg member 53 on the L-shaped placement rack 7, the end of the lifting and grasping component 3 moves to the position below the two sides of the "T" shape at the top of the side leg member 53. Then, the lifting component 31 rises so that the limiting component 4 at the end of the telescopic grasping component 32 clamps the front and back surfaces of the "T" shape at the top of the side leg member 53. The lifting component 31 continues to rise to separate the lower end of the side leg member 53 from the L-shaped placement rack 7, and then the telescopic grasping component 32 contracts, thereby realizing the picking up of the side leg member 53.

[0039] As Figure 7 shown, the L-shaped placement rack 7 includes an L-shaped bracket 71. A fixed seat 72 is arranged at the horizontal end of the L-shaped bracket 71. A fixed groove 721 matching the shape of the lower end of the side leg member 53 is arranged on the fixed seat 72. The crane can place the lower end of the side leg member 53 in the fixed groove 721 of the fixed seat 72. At the top of the vertical end of the L-shaped bracket 71, there is an auxiliary seat 73. An auxiliary groove 731 matching the radian of the side leg member 53 is arranged on the auxiliary seat 73. After the crane places the lower end of the side leg member 53 in the fixed groove 721 of the fixed seat 72, the side leg member 53 can lean on the auxiliary seat 73 to complete the placement of the side leg member 53 and wait to be grasped. Preferably, a buffer pad is arranged in the auxiliary groove 731, and the buffer pad can be a rubber pad to prevent the side leg member 53 from being damaged by knocking.

[0040] It should be noted that, in order to improve the reliability of the side support leg member 53 during transportation, a support seat 8 is provided at the lower side position of the chassis assembly 1. A support groove 81 matching the shape of the lower end of the side support leg member 53 is provided on the support seat 8. After the lifting and grasping assembly 3 grasps the side support leg member 53, the lower end of the side support leg member 53 can be inserted into the support seat 8 for transportation. Preferably, a buffer pad is also provided in the support groove 81, and the buffer pad can be a rubber pad to prevent the side support leg member 53 from being knocked and damaged and prevent the lower end of the side support leg member 53 from sliding in the support groove 81.

[0041] As Figure 10-12 shown, the chassis assembly 1 includes a base frame 11. The lifting and grasping assembly 3 is integrally detachably connected above the base frame 11. In this embodiment, the lifting and grasping assembly 3 is integrally fixed above the base frame 11 by bolts.

[0042] A rotating shaft disc 12 is hingedly provided at the front and rear ends below the base frame 11 respectively. The rotating shaft disc 12 can rotate horizontally relative to the base frame 11. The rotating shaft disc 12 is fixedly connected to the wheel axle bracket 13. A wheel is provided at each end of the wheel axle bracket 13. Each wheel is respectively connected to a set of mobile motors and speed reducers. By controlling the four mobile motors to control the rotation speeds of the four wheels, the movement of the chassis assembly 1 can be realized, including forward movement, backward movement and steering, etc.

[0043] The guiding assembly 2 is provided on the wheel axle bracket 13. The guiding assembly 2 includes a guiding sensor and a guiding unit. The guiding sensor is fixed on the wheel axle bracket 13, and the guiding unit is arranged on the ground. The guiding sensor can control the moving direction of the chassis assembly 1 according to the position of the guiding unit, so that the chassis assembly 1 walks along a preset route. Specifically, the guiding assembly 2 adopted in this embodiment is magnetic tape navigation. The guiding assembly 2 includes a magnetic sensor 21 and a magnetic tape. The magnetic sensor 21 is fixed on the wheel axle bracket 13, and the magnetic tape is laid on the ground. The magnetic sensor 21 controls the moving path of the chassis assembly 1 of the present invention by detecting the position of the magnetic tape in real time. The guiding assembly 2 can also adopt other existing navigation methods, such as magnetic nail navigation, color tape navigation, laser reflection navigation, etc.

[0044] As Figure 10 shown, a control panel and a display screen 14 are provided at the rear of the base frame 11. Both the control panel and the display screen 14 are connected to the processor. The control panel can manually control the operating parameters of the present invention, such as driving speed, lifting speed, telescopic speed, etc.

[0045] Preferably, as Figure 3 shown, a remote control module 15 is also provided on the base frame 11. The remote control module 15 is wirelessly connected to a remote controller. The remote controller can control the operating state of the present invention, such as the lifting and telescoping of the lifting and grasping assembly 3, the start and stop of the wheels, the driving speed and steering, etc.

[0046] To improve the safety of the present invention during operation, a plurality of emergency stop buttons are provided on the sides of the chassis 11, so that in case of special situations, the emergency stop buttons can be pressed to stop the machine. Preferably, anti-collision guardrails 16 are provided at the lower positions on the front and rear sides of the chassis 11, and pedestrian detection sensors 17 are provided on the anti-collision guardrails 16. The pedestrian detection sensors 17 can detect whether there are pedestrians around the vehicle. When pedestrians are detected, the vehicle stops immediately. After the pedestrians leave, the vehicle continues to drive according to the original plan. The pedestrian detection sensors 17 adopted in this embodiment have a detection range of 270°, and the pedestrian detection sensors 17 are arranged diagonally on the anti-collision guardrails 16 on the front and rear sides.

[0047] It should be noted that, to further improve safety, a safety spring strip 18 is movably connected to the anti-collision guardrail 16 through a guide rail 8. The safety spring strip 18 is connected to the anti-collision guardrail 16 through an elastic component 181. Under the action of an external force, the safety spring strip 18 can move towards the inner side of the anti-collision guardrail 16. A touch switch 182 is provided on the inner side of the anti-collision guardrail 16. When the safety spring strip 18 touches the touch switch 182, the chassis assembly 1 stops immediately. Preferably, to improve the reliability of the operation of the safety spring strip 18, an elastic component 181 is connected to each side of the safety spring strip 18, and the touch switch 182 is provided at the middle position in the length direction on the inner side of the anti-collision guardrail 16.

[0048] To facilitate the transportation of the present invention, lifting hooks are provided around the upper part of the chassis 11. The lifting hooks can facilitate the hoisting of the present invention onto a transport vehicle for long-distance transportation. In addition, towing hooks are provided on the front and rear sides of the chassis 11 to facilitate the towing of the present invention by a rescue vehicle.

[0049] To improve the environmental protection of the present invention, a battery pack is used for power supply. The battery pack is arranged at the middle position below the chassis 11 to ensure that the center of gravity of the present invention is centered, thereby reducing the risk of rollover, and it can also remain horizontal during hoisting.

[0050] Preferably, a plurality of storage boxes 19 are provided on the left and right sides of the chassis 11 to facilitate the placement of tools and the like.

[0051] When the intelligent equipment for transporting and installing the side leg members of an urban utility tunnel actually transports and installs the side leg members 53, the following steps are included:

[0052] S1. Use a crane to place the chassis assembly 1 into the utility tunnel through the wellhead and drive away from below the wellhead;

[0054] S3. Use a crane to place the side leg member 53 into the L-shaped placement rack 7 in the pipe gallery through the wellhead;

[0055] S4. The chassis assembly 1 moves between the two L-shaped placement racks 7. Subsequently, the lifting assembly 31 cooperates with the telescopic grasping assembly 32 to extend the limiting assembly 4 under the "T" shape at the top of the side leg member 53. Then, the lifting assembly 31 is raised to clamp the limiting assembly 4 on the front and back sides of the "T" shape at the top of the side leg member 53. The lifting assembly 31 is continuously raised to lift the side leg member 53 off the L-shaped placement rack 7.
