[0042] like Figure 1 As shown, this embodiment provides an underground utility tunnel tool vehicle, including a drive vehicle 1, a transport vehicle 2, a pair of tracked assemblies 3, a fire-fighting assembly 4, and a control module. The drive vehicle 1 and the transport vehicle 2 are connected in a towing manner. The transport vehicle 2 is used to transfer tools. The two tracked assemblies 3 are respectively arranged on both sides of the drive vehicle 1 for climbing stairs. The fire-fighting assembly 4 is arranged on the drive vehicle 1 and can spray fire extinguishing material. The control module is signal-connected to the drive vehicle 1 and the tracked assemblies 3, and the control module can control the drive vehicle 1 and the tracked assemblies 3 to move.

[0043] The tool vehicle has the following advantages: (1) On a flat road surface, the drive vehicle 1 can be operated to travel quickly in underground cable trenches and underground pipe corridors; (2) The tool vehicle adopts a wheel-track composite structure. When on a stepped road surface, the track assembly is used to drive to complete the step climbing; (3) The manned tool vehicle is equipped with a fire-fighting assembly 4, which can spray fire extinguishing materials to help the driver get out of the dangerous environment quickly; (4) The drive vehicle 1 and the track assembly 3 can be operated through the control module so that the drive vehicle 1 can be operated outside the drive vehicle 1 in a narrow space.

[0044] like Figure 2 As shown, in this embodiment, the driving vehicle 1 includes a frame 11, a front fork 12, a drive unit, a lamp, and a seat 13; the front fork 12 is disposed at the front end of the frame 11, the drive unit is disposed at the rear end of the frame 11, the lamp is mounted on the front fork 12, and the seat 13 is detachably mounted on the frame 11.

[0045] like Figure 2As shown, in this embodiment, the two track assemblies 3 are movably disposed on both sides of the frame 11. When traveling through the underground utility tunnel, steps with height differences are unavoidable. By providing a set of track assemblies 3 on each side of the driving vehicle 1, the driving vehicle 1 can be driven to travel on the stepped road surface by means of the track assemblies 3. Specifically, when traveling on a flat road surface, the track assembly 3 is in a high position, and the lowest point of the track assembly 3 is higher than the center point of the wheel of the driving vehicle 1. At this time, the track assembly 3 does not contact the road surface. When traveling on a stepped road surface, the track assembly 3 is in a low position, and the lowest point of the wheel of the driving vehicle 1 is higher than the center point of the track assembly 3. At this time, the track assembly 3 directly contacts the stepped road surface.

[0046] like Figure 2 As shown, the track assembly 3 further includes: a swaying mechanism 31 and a track body 32. The swaying mechanism 31 is fixed on the frame 11 and is drivenly connected to the track body 32. The swaying mechanism 31 drives the track body 32 to change its position. The track body 32 is equipped with a motor to drive the track body 32 to move. The control module is signal-connected to the swaying mechanism 31 and the track body 32 respectively to control the swaying mechanism 31 to drive the track body 32 and to control the track body 32 to move.

[0047] like Figure 2 As shown, the swing mechanism 31 further includes a housing, a swing arm 311, and a drive motor 312. The housing is installed at the bottom of the frame 11. The swing arm 311 is Z-shaped, with one end rotatably connected to the track body 32 and the other end extending into the housing and rotatably connected to it. The drive motor 312 is disposed inside the housing and is driven by the swing arm 311. The drive motor 312 drives the swing arm 311 to swing, thereby moving the track body 32 up and down to change its position. Preferably, the housings of the two swing devices are integrated together and installed at the bottom of the frame 11.

[0048] like Figure 2As shown, further, there are two swing arms 311, and the swing mechanism 31 also includes two driven wheels 313, a rack 314, and a drive wheel 315; the two driven wheels 313 are respectively fixed to one end of the swing arm 311 that extends into the housing, the rack 314 is slidably disposed on the housing and meshes with the two driven wheels 313, and the drive wheel 315 is disposed at the output end of the drive motor 312 and meshes with the rack 314; the drive motor 312 drives the rack 314 to slide through the drive wheel 315, and the rack 314 drives the two driven wheels 313 to rotate synchronously, so that the swing arm 311 drives the track body 32 to move; by setting a double swing arm 311 structure, the rigidity and strength of the track assembly 3 support structure are enhanced, and the reliability is improved.

[0049] like Figure 2 As shown, the swing mechanism 31 further includes a connecting rod 316, the two ends of which are respectively sleeved on the two swing arms 311 near the track body 32, further enhancing the rigidity and strength of the track assembly 3 support structure.

[0050] like Figure 3 , 4 As shown, in this embodiment, the tool cart also includes a connecting component 5. The seat 13 and the frame 11 are detachably connected via the connecting component 5. The connecting component 5 includes a limiting block 51 and a snap-fit ​​component 52. The limiting block 51 is disposed on the bottom surface of the seat 13, and the snap-fit ​​component 52 is disposed on the frame 11. The limiting block 51 and the snap-fit ​​component 52 snap together to achieve the detachable connection of the seat 13 and the frame 11. Due to the environmental conditions of the underground utility tunnel, any driving vehicle 1 must consider whether its size allows for smooth passage when entering the underground utility tunnel. Therefore, through the detachable structural design of the seat 13 and the frame 11, when entering lower areas, the seat 13 can be disassembled to reduce the height of the driving vehicle 1, so that it can normally enter or exit the underground utility tunnel and underground cable trench.

[0051] like Figure 3 , 4 As shown, the snap-fit ​​component 52 further includes a snap-fit ​​cylinder 521 and a pin 522; the pin 522 is disposed in the inner cavity of the snap-fit ​​cylinder 521, and the limiting block 51 has a limiting hole at one end; specifically, the limiting block 51 extends into the inner cavity of the snap-fit ​​cylinder 521, and then the pin 522 is inserted into the limiting hole to realize the snap-fit ​​between the limiting block 51 and the snap-fit ​​component 52.

[0052] like Figure 5As shown, the retaining sleeve 521 further includes a first cylindrical portion 5211 and a second cylindrical portion 5212. One end of the first cylindrical portion 5211 and the second cylindrical portion 5212 are vertically connected, and the inner cavities of the first cylindrical portion 5211 and the second cylindrical portion 5212 are in communication. The limiting block 51 extends into the inner cavity of the first cylindrical portion 5211 and slides with the first cylindrical portion 5211. The pin 522 is disposed in the inner cavity of the second cylindrical portion 5212. When the limiting hole of the limiting block 51 reaches the position of the second cylindrical portion 5212, the pin 522 extends from the second cylindrical portion 5212 to the first cylindrical portion 5211 and inserts into the limiting hole to engage with the limiting block 51.

[0053] like Figure 6 As shown, further, the pin 522 includes a pin 5221, a slider 5222, an elastic element 5223, and a pressing block 5224; the slider 5222 is slidably disposed in the inner cavity of the second cylindrical portion 5212; the pin 5221 is adapted to the limiting hole; the pin 5221 is fixed to the side of the slider 5222 near the first cylindrical portion 5211; the elastic element 5223 is disposed between the second cylindrical portion 5212 and the slider 5222; under normal conditions, the elastic element 5223 pushes the slider 5222 to move toward the first cylindrical portion 5211; the slider 5222... The upper and lower sides of part 2 are provided with sliding grooves, and the extension direction of the sliding grooves is inclined to the axial direction of the second cylindrical part 5212; the pressing block 5224 is located on the side of the second cylindrical part 5212, one end of the pressing part 52241 extends into the inner cavity of the second cylindrical part 5212 and is slidably disposed on the sliding groove of the slider 5222, and the slider 5222 can slide in a direction perpendicular to the axial direction of the second cylindrical part 5212; when the slider 5222 slides toward the second cylindrical part 5212, it slides away from the first cylindrical part 5211 in the cooperation with the sliding groove.

[0054] like Figure 7 As shown, the pressing block 5224 further includes a pressing part 52241, two connecting parts 52242, and two sliding parts 52243. The pressing part 52241 is located on the side of the second cylindrical part 5212. The two connecting parts 52242 are arranged vertically and vertically on one side of the pressing part 52241. The two sliding parts 52243 are respectively fixed to one end of the connecting part 52242 and located on the opposite side surface of the two connecting parts 52242. The connecting part 52242 passes through the second cylindrical part 5212. The two sliding parts 52243 are respectively slidably engaged with the corresponding two sliding grooves.

[0055] Specifically, when the pressing part 52241 is pressed, the sliding part 52243 and the sliding groove cooperate to push the slider 5222 to translate away from the first cylindrical part 5211, causing the pin 5221 to retract from the first cylindrical part 5211; when the pressing part 52241 is released, the slider 5222 is pushed towards the first cylindrical part 5211 by the elastic member 5223, causing the pin 5221 to extend out of the first cylindrical part 5211; thus, the pin 5221 is controlled to insert into or leave the limiting hole, realizing the engagement of the limiting block 51 and the snap-fit ​​member 52.

[0056] like Figure 3 , 5 As shown, the connecting assembly 5 further includes a slider 53, the extension direction of which is the same as the axial direction of the first cylindrical portion 5211. The slider 53 includes a slider strip and a slide rail. The slider strip is fixed to the bottom end of the seat 13, and the slide rail is fixed to the frame 11. The slider strip is detachably threaded through the slide rail and slides in cooperation with the slide rail. Thus, the slider 53 is used to limit the left and right sides of the seat 13 to improve the stability of the seat 13.

[0057] In this embodiment, the control module is a wireless remote controller, which is wirelessly connected to the track assembly 3 and the driving vehicle 1 respectively. When driving on a stepped road surface, the driver walks on the road surface and controls the operation of the track assembly 3 through the operation control module. This reduces the load on the track assembly 3, which is beneficial for driving the driving vehicle 1 and also makes it easier for the driver to control.

[0058] like Figure 1 , 3 As shown, in this embodiment, the fire-fighting component 4 includes a fire extinguisher, a nozzle 41, and a control switch 42. The seat 13 has a box structure with a receiving cavity. The fire extinguisher is disposed in the receiving cavity of the seat 13. The nozzles 41 are respectively disposed on both sides of the driving vehicle 1 and connected to the fire extinguisher through pipes. The control switch 42 is connected to the fire extinguisher. By operating the control switch 42, the fire extinguisher is controlled to spray extinguishing material from the nozzles 41. Preferably, the nozzles 41 are disposed on both sides of the seat 13.

[0059] like Figure 1 , 3As shown, further, the control switch 42 is a foot pedal, which is mounted on the vehicle frame 11. By pressing the control switch 42, the fire extinguisher is controlled to spray extinguishing material from the nozzle 41. In other embodiments, the control switch 42 can also be a button, which is mounted on the handlebars of the driving vehicle 1. Specifically, in the event of a fire, the foot pedal is used to control the nozzles 41 on both sides of the driving vehicle 1 to spray extinguishing material, thus achieving a fire prevention function. The underground utility tunnel has a simple geographical environment, and fires often spread to the sides. Therefore, the nozzles 41 on both sides of the driving vehicle 1 can directly spray fireproof material onto the walls on both sides of the underground utility tunnel, further preventing the spread of fire.

[0060] In addition, oxygen cylinders and fireproof masks can be placed in the containment cavity to help staff leave the scene and increase their chances of escape.

[0061] like Figure 1 , 3 As shown, in this embodiment, the tool vehicle also includes a driving recorder 6, which includes a recording module, a distress signal module, and a positioning module. The recording module is used to record the working conditions in the underground utility tunnel. The distress signal module is used to send a distress signal, and the positioning module is used to locate the position of the driving vehicle 1. When encountering a sudden emergency, the distress signal can be sent through the distress signal module to notify external personnel, and the position of the driving vehicle 1 can be quickly located through the positioning module to facilitate rescue work for the staff.

[0062] Finally, it should be noted that the above descriptions are merely preferred embodiments of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
