Description

Technical Field

[0001] The utility model belongs to the technical field of fire-fighting robots, and particularly relates to a tracked fire-fighting robot. Background Art

[0002] Most new energy vehicles catch fire due to the thermal runaway of the power battery at the bottom of the vehicle. At this time, it is often necessary for a fire-fighting robot to go deep under the vehicle to extinguish the fire point. By extinguishing the fire at the bottom of the vehicle and directly spraying the fire extinguishing medium towards the fire source, the fire extinguishing efficiency can be greatly improved, and the situation of the loss being enlarged due to the failure to extinguish the fire in time caused by the thermal fire of the power battery at the bottom of the new energy vehicle can be avoided as much as possible.

[0028] In order to enable those skilled in the art to better understand the technical solutions in this utility model, the following will clearly and completely describe the technical solutions in the embodiments of this utility model with reference to the accompanying drawings in the embodiments of this utility model. Obviously, the described embodiments are only a part of the embodiments of this utility model, rather than all the embodiments. Based on the embodiments in this utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of this utility model.

[0029] As Figure 1 shown, a tracked fire robot in an embodiment of this utility model includes a fire robot main body 1. A pair of first driving wheels 7 are respectively installed on both sides of the fire robot main body 1. A plurality of first driven wheels 8 are also installed on both sides of the fire robot main body 1, and the plurality of first driven wheels 8 are all located between a pair of first driving wheels 7. A crawler belt 9 is installed on the first driving wheels 7, and the first driven wheels 8 are used to support the crawler belt 9. A motor 10 is also installed on the fire robot main body 1. The number of motors 10 is two, which are respectively installed on both sides of the fire robot main body 1 and used to drive the first driving wheels 7 on both sides. During the startup process of the motor 10, one of the first driving wheels 7 on both sides will be driven to rotate respectively. During the rotation process of the first driving wheels 7, the crawler belt 9 can be driven to rotate, thereby realizing the operation of the tracked robot.

[0030] As Figure 1 shown, two first spraying assemblies 2 are installed at the upper end of the fire robot main body 1. The two first spraying assemblies 2 are used to spray the fire extinguishing medium in the vertical direction, which is conducive to spraying from the bottom of the new energy vehicle upwards and is conducive to extinguishing the fire caused by the fire at the bottom of the vehicle. A second spraying assembly 3 is also installed on the fire robot main body 1. The second spraying assembly 3 is used to spray the fire extinguishing medium in the horizontal direction. A connecting pipe 4 is installed between the first spraying assembly 2 and the second spraying assembly 3, and the connecting pipe 4 is used to connect the first spraying assembly 2 and the second spraying assembly 3.

[0031] AsFigures 2 to 5 As shown in the figure, connecting plates 11 are respectively installed on both sides of the main body 1 of the fire-fighting robot. A pair of second driving wheels 12 and several second driven wheels 13 are installed on the connecting plates 11, and the second driven wheels 13 are located between the pair of second driving wheels 12. The crawler 9 is installed on the first driving wheel 7 and the second driving wheels 12. The connecting plates 11 increase the contact area between the lower end surface of the main body 1 of the fire-fighting robot and the ground, minimizing the wear of the chassis of the crawler-type fire-fighting robot when used in an environment with uneven ground, and at the same time being able to prevent the crawler-type fire-fighting robot from traveling too fast and tipping over during the process of crossing obstacles. This enables the crawler-type fire-fighting robot to adapt to a wider range of terrains.

[0032] As Figures 2 to 7 shown in the figure, the connecting plate 11 includes a first plate body 1101 and a second plate body 1102. The first plate body 1101 and the second plate body 1102 are slidably connected, and the second driving wheels 12 and the second driven wheels 13 are installed on the second plate body 1102. Through the slidable connection between the first plate body 1101 and the second plate body 1102, the height of the connecting plate 11 can be changed, thereby changing the distance between the lower end surface of the main body 1 of the fire-fighting robot and the ground. The height between the main body 1 of the fire-fighting robot and the ground can be adjusted for different vehicles, and at the same time, the lower end surface of the main body 1 of the fire-fighting robot is not likely to rub against the ground, minimizing the situation of friction between the lower end surface of the main body 1 of the fire-fighting robot and the ground due to the lower end surface being too close to the ground.

[0033] Specifically, as Figures 2 to 7 shown in the figure, a slot 11013 is opened at the upper end of the connecting plate 11, and L-shaped positioning blocks 16 that match the slot 11013 are respectively fixedly connected to both sides of the main body 1 of the fire-fighting robot. The slot 11013 can be inserted into the L-shaped positioning block 16, and the slot 11013 and the L-shaped positioning block 16 are in interference fit, that is, they are not easily loosened after being inserted tightly, facilitating the disassembly of the connecting plate 11 and the main body 1 of the fire-fighting robot. With the cooperation of the crawler 9, the situation of the main body 1 of the fire-fighting robot and the connecting plate 11 becoming detached can be further reduced. To further improve the fixing stability of the L-shaped positioning block 16 and the slot 11013, the L-shaped positioning block 16 and the slot 11013 can also be fixed by a clamping method.

[0034] Furthermore, to ensure the fixing stability of the main body 1 of the fire-fighting robot and the connecting plate 11, a plurality of first through holes 11011 are opened on the first plate body 1101, and fixing bolts are installed on the first plate body 1101. The fixing bolts penetrate through the slot 11013 and are in threaded connection with the main body 1 of the fire-fighting robot. The fixing bolts can make the fixing of the main body 1 of the fire-fighting robot and the connecting plate 11 more stable and not easily become detached.

[0035] AsFigures 2 to 7 As shown in the figure, a second chute 11012 is formed in the first plate body 1101, and a sliding plate 11021 matching the second chute 11012 is fixedly connected to the second plate body 1102. The second chute 11012 and the sliding plate 11021 are slidably connected. That is, the first plate body 1101 and the second plate body 1102 are slidably connected through the cooperation of the second chute 11012 and the sliding plate 11021. A plurality of second through holes 11014 are formed in the side wall of the first plate body 1101, and a waist-shaped hole 11022 matching the second through holes 11014 is formed in the second plate body 1102. A bolt 17 is installed on the first plate body 1101. The bolt 17 sequentially passes through the second through holes 11014 and the waist-shaped hole 11022, and can fasten the first plate body 1101 and the second plate body 1102 together, so that the first plate body 1101 and the second plate body 1102 do not continue to slide. In this way, after the connecting plate 11 is installed on the main body 1 of the fire-fighting robot, by sliding the first plate body 1101 and the second plate body 1102, after changing the distance between the main body 1 of the fire-fighting robot and the ground, the first plate body 1101 and the second plate body 1102 are locked by the bolt 17, and the change of the distance between the main body 1 of the fire-fighting robot and the ground is completed, so that the lower end surface of the main body 1 of the fire-fighting robot is not easily in contact with the ground, and the service life is not easily affected by friction.

[0036] However, when adjusting the connecting plate 11, it is also restricted by the crawler 9. If the distance between the main body 1 of the fire-fighting robot and the ground needs to be small, the connecting plate 11 needs to be adjusted shorter. At this time, the connection tightness between the crawler 9 and the second driving wheel 12 and the first driving wheel 7 will become loose, which may cause the crawler 9 not to rotate with the first driving wheel 7 when the first driving wheel 7 rotates. To solve the above problems, as Figures 2 to 7 shown in the figure, an extension part 101 is installed on a side wall of the main body 1 of the fire-fighting robot away from the motor 10. A first chute 1011 is formed in the extension part 101, and one of the first driving wheels 7 is slidably connected in the first chute 1011. By sliding the first driving wheel 7, the crawler 9 can be stretched or contracted, so that the crawler 9 can adapt to the adjustment of the connecting plate 11. After adjusting the connecting plate 11, it is not necessary to replace the crawler 9, which greatly saves the time for adjusting the distance between the main body 1 of the fire-fighting robot and the ground.

[0037] Specifically, as Figures 2 to 7As shown in the figure, a slider 6 that matches the first chute 1011 is fixedly connected to the first driving wheel 7. A positioning groove 10111 is formed on the side wall of the first chute 1011, and a convex portion 601 that matches the positioning groove 10111 is fixedly connected to the slider 6. The cooperation of the positioning groove 10111 and the convex portion 601 can prevent the slider 6 from disengaging from the first chute 1011, avoiding the situation where the first driving wheel 7 is separated from the main body 1 of the fire-fighting robot during the process of adjusting the slider 6. A threaded rod 14 penetrates through the slider 6, and the threaded rod 14 is threadedly connected to the slider 6. One end of the threaded rod 14 is rotatably connected to the extension portion 101. That is, a bearing 15 is fixedly connected to one end of the threaded rod 14, and the bearing 15 is fixedly connected to a side wall of the extension portion 101. During the process of rotating the threaded rod 14, the slider 6 can be driven to move, thereby changing the position of the first driving wheel 7 and realizing the stretching or contraction of the track 9.

[0038] The adjustment distance of the first driving wheel 7 is in a 1:1 ratio with the adjustment height of the connecting plate 11. That is, for every distance the first driving wheel 7 stretches, the connecting plate 11 should contract by the same distance, so as to ensure that the track 9 is always tightly connected to the first driving wheel 7 and the second driving wheel 12.

[0039] Preferably, the first plate body 1101 and the second plate body 1102 can be specifically connected by damping sliding. With the intervention of damping, after the adjustment of the first plate body 1101 and the second plate body 1102 is completed, it is not necessary to further lock the first plate body 1101 and the second plate body 1102. Then, after adjusting the slider 6 through the threaded rod 14, the first driving wheel 7 can be used to tighten the track 9, and there is no need to further fix it with bolts, which can greatly improve the adjustment speed of the tracked fire-fighting robot and enable the tracked fire-fighting robot to carry out fire-fighting operations more quickly.

[0040] As Figure 3 shown, to further ensure that the tightness of the two tracks 9 is consistent, scale lines 5 are provided on the first chute 1011. Through the scale lines 5, the positions of the two sliders 6 can be confirmed, and the two sliders 6 are made to be on the same scale, as much as possible to ensure the consistency of the tension of the two first driving wheels 7 on the track 9.

[0041] When used on flat ground, as Figure 1 shown, connect the tracked fire-fighting robot to the fire hose, and then remotely control the tracked fire-fighting robot to enter the fire scene for fire extinguishing.

[0042] When used on non-flat ground, as Figure 2As shown in the figure, first, the connecting plate 11 needs to be installed on the main body 1 of the fire-fighting robot. During installation, the slot 11013 needs to be aligned with the L-shaped positioning block 16, and the slot 11013 is snapped into the L-shaped positioning block 16, and then it can be fixed by fixing bolts. Then, the crawler 9 is installed on the first driving wheel 7 and the second driving wheel 12, and by rotating the threaded rod 14, the position of the slider 6 is adjusted, so as to adjust the first driving wheel 7 to tighten the crawler 9. At this time, the distance between the lower end of the main body 1 of the fire-fighting robot and the ground is relatively large, and the upper end surface of the main body 1 of the fire-fighting robot is not higher than the chassis height of the vehicle, that is, the tracked fire-fighting robot after installing the connecting plate 11 can still enter under the vehicle for fire-fighting operations.

[0043] It should be noted that the connecting plate 11 can be selectively installed after purchasing the tracked fire-fighting robot. According to the actual use situation, the connecting plate 11 is adjusted. The connecting plate 11 is used to change the distance between the tracked fire-fighting robot and the ground, and improve the adaptability of the tracked fire-fighting robot to operate in different environments. It is not installed after a fire occurs. Of course, if it is difficult for the tracked fire-fighting robot to carry out fire-fighting operations without installing the connecting plate 11, it can also be installed and adjusted after a fire occurs.
