Technical Field

[0001] The utility model relates to the technical field of fire-fighting robots, in particular to a chassis for fire-fighting robots. Background Art

[0002] Firefighting robots can replace firefighting rescue personnel to enter dangerous disaster scenes, thereby ensuring the personal safety of firefighting personnel. Firefighting robots are usually composed of a chassis, camera, firefighting equipment and alarm equipment, etc. Firefighting robots are usually driven by batteries inside the chassis.

[0003] According to the utility model with authorization announcement number CN211986770U, a rotatable chassis for a fire-fighting robot is disclosed, including a mobile base, a walking wheel is installed at the bottom of the mobile base, a rotating seat is rotatably installed on the top of the mobile base, a water tank is fixedly installed on the top of the rotating seat, a pump body is fixedly installed on one side of the water tank, one end of a water pipe is fixedly installed on the water outlet of the pump body, and the other end of the water pipe is fixedly connected to a spray gun, and a rotating plate is rotatably installed on the top of the rotating seat.

[0004] Although the equipment can adjust the spraying direction of the spray gun and the spraying angle of the spray gun, and can make the spray gun swing back and forth continuously, thereby increasing the spraying range, the fire-fighting robot chassis of the equipment has poor passability when in use and can only move on a relatively flat and solid bottom surface. When encountering a deep wading environment, the fire-fighting robot chassis cannot allow the fire-fighting robot to pass more safely, resulting in the inability to survey dangerous disaster sites in the wading environment, reducing the use effect of the fire-fighting robot chassis; for this reason, we provide a fire-fighting robot chassis to solve the above problems. Utility Model Content

[0005] The purpose of the utility model is to make up for the deficiencies of the prior art and to provide a chassis for a fire-fighting robot.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a chassis for a fire-fighting robot, comprising a bottom plate, an inflation mechanism is arranged inside the bottom plate, the inflation mechanism comprises four inflation boxes, the outer surface of each inflation box is fixedly connected to the inner wall of the bottom plate, an inflation cylinder is arranged inside each inflation box, the outer surface of each inflation cylinder is fixedly connected to a rubber telescopic cylinder, a side of each rubber telescopic cylinder away from the inflation cylinder is fixedly connected to an expansion airbag, an inner top wall of each inflation box is respectively fixedly mounted with an inflation pump and an exhaust pump, the air outlet end of each inflation pump passes through the inflation cylinder and extends to the interior of the inflation cylinder, and the air inlet end of each exhaust pump passes through the inflation cylinder And it extends to the interior of the inflation cylinder, each of the inflation cylinders has two limiting rings fixedly installed on the inner wall, the interior of each group of limiting rings is connected to a connecting rod for common rotation, the inner wall of each limiting ring is fixedly installed with a clockwork spring, the inner wall of each clockwork spring is fixedly connected to the outer surface of the connecting rod, the outer surface of each connecting rod is sleeved with a winding rope, each end of the winding rope away from the connecting rod passes through the rubber telescopic cylinder and is fixedly connected to the inner wall of the inflatable airbag, the outer surface of each winding rope is fixedly installed with a connecting block, and each of the connecting blocks has an elastic rope fixedly installed on one side away from each other, and each elastic rope is fixedly connected to the inner wall of the inflatable airbag at one end away from the connecting block.

[0007] Furthermore, four support blocks are fixedly mounted on the bottom surface of the base plate, a rolling wheel is rotatably connected to the interior of each support block, and an outer surface of each rolling wheel is provided with anti-skid grooves arranged at equal distances.

[0008] Furthermore, a connection seat is fixedly mounted on the upper surface of the base plate, and four connection through holes are opened on the upper surface of the connection seat.

[0009] Furthermore, two movable frames are fixedly mounted on the upper surface of the bottom plate, and a pull ring is rotatably connected inside each of the movable frames.

[0010] Furthermore, two fixing rings are fixedly mounted on the outer surface of each of the inflatable cylinders, and a side surface of each group of the fixing rings that is away from each other is fixedly connected to the interior of the inflatable box.

[0011] Furthermore, the air inlet end of each of the inflation pumps and the air outlet end of each of the exhaust pumps are fixedly connected with a one-way valve, and the top end of each of the one-way valves penetrates the inflation box and extends to the top of the inflation box.

[0012] Furthermore, a sealing plate is provided on the side of each of the inflation boxes away from the bottom plate, three electric push rods are fixedly connected to the side of each of the sealing plates close to the inflation box, and one end of each of the electric push rods away from the sealing plate is fixedly connected to the inner wall of the inflation box.

[0013] Furthermore, two limiting disks are fixedly mounted on the outer surface of each connecting rod, and the side surfaces of each group of limiting disks close to each other are in contact with the outer surface of the winding rope.

[0014] Compared with the prior art, the chassis for the fire-fighting robot has the following beneficial effects:

[0015] The utility model can deliver external air into the interior of the inflation cylinder by means of the suction provided by the inflation pump, and then as the air pressure inside the inflation cylinder increases, the rubber telescopic cylinder and the expansion airbag are forced to expand, thereby forming four airbags outside the bottom plate. At this time, when the fire-fighting robot chassis passes through a deeper wading environment, the water-afraid equipment on the chassis will not come into contact with the water body, so that the chassis floats on the water surface, which enables the fire-fighting robot chassis to cooperate with the inflation mechanism to increase the passability, and pass through the wading area more safely, making it convenient for the fire-fighting robot to survey dangerous disaster sites in the wading environment, and further increasing the use effect of the fire-fighting robot chassis. The suction force provided by the exhaust pump can quickly draw out the gas inside the expansion airbag and the rubber telescopic cylinder, so that the fire-fighting robot chassis can quickly return to its original state after leaving the wading environment, thereby preventing the undeflated expansion airbag from affecting the subsequent fire-fighting robot's survey tasks.

[0016] The utility model provides a limit ring in conjunction with a clockwork spring. When the expansion airbag and the rubber telescopic tube are inflated, the pressure will pull the elastic rope to extend and cooperate with the reeling rope to pull the connecting rod to rotate, so that the clockwork spring accumulates elastic force. Then, when the internal gas of the expansion airbag and the rubber telescopic tube is discharged outwardly, the elastic force accumulated by the clockwork spring and the elastic force of the elastic rope cooperate with the connecting block to pull the expansion airbag and the rubber telescopic tube back into the inflation box, so that they can be quickly prepared for the next use. At the same time, the expansion airbag and the rubber telescopic tube will not expand outward, which prevents the expansion airbag and the rubber telescopic tube from affecting the movement of the chassis of the fire-fighting robot, thereby achieving the effect of further increasing the smoothness of the movement of the chassis of the fire-fighting robot.

DETAILED DESCRIPTION

[0022] The principles and features of the present invention are described below in conjunction with the accompanying drawings. The examples given are only used to explain the present invention and are not used to limit the scope of the present invention.

[0023] This embodiment provides a chassis for a fire-fighting robot, which is used for the chassis of the fire-fighting robot to pass through a water-wading environment smoothly. The inflation mechanism 2 can be used to allow the chassis of the fire-fighting robot to pass through a water-wading environment smoothly for dangerous inspections.

[0024] See also Figure 1 to Figure 4 A chassis for a fire-fighting robot includes a base plate 1, an inflation mechanism 2 is arranged inside the base plate 1, the inflation mechanism 2 includes four inflation boxes 201, the outer surface of each inflation box 201 is fixedly connected to the inner wall of the base plate 1, four support blocks 212 are fixedly installed on the bottom surface of the base plate 1, each support block 212 is rotatably connected to a rolling wheel 213, and the outer surface of each rolling wheel 213 is provided with anti-skid grooves 214 arranged at equal distances. The support blocks 212 cooperate with the rolling wheels 213 to allow the device to move smoothly, and the anti-skid grooves 214 can increase the friction of the rolling wheels 213.

[0025] An inflation cylinder 202 is provided inside each inflation box 201, and the outer surface of each inflation cylinder 202 is fixedly connected to a rubber telescopic cylinder 203. A connecting seat 215 is fixedly installed on the upper surface of the base plate 1, and four connecting through holes 216 are opened on the upper surface of the connecting seat 215. The connecting seat 215 cooperates with the connecting through holes 216 and can use bolts and other fixing parts to add other equipment of the fire-fighting robot to the base plate 1, thereby ensuring that other equipment can be smoothly connected to the base plate 1.

[0026] The side of each rubber telescopic cylinder 203 away from the inflation cylinder 202 is fixedly connected to an expansion airbag 204, and the inner top wall of each inflation box 201 is respectively fixedly installed with an inflation pump 205 and an exhaust pump 206. Two movable frames 217 are fixedly installed on the upper surface of the bottom plate 1. The interior of each movable frame 217 is rotatably connected with a pull ring 218. The device can be pulled by a traction device through the movable frame 217 and the pull ring 218, so that the device can be moved conveniently by the staff after the device loses power.

[0027] The air outlet end of each air pump 205 passes through the air cylinder 202 and extends to the interior of the air cylinder 202. The air inlet end of each exhaust pump 206 passes through the air cylinder 202 and extends to the interior of the air cylinder 202. Two fixing rings 219 are fixedly installed on the outer surface of each air cylinder 202. The side faces of each set of fixing rings 219 that are away from each other are fixedly connected to the interior of the air box 201. The fixing rings 219 can reinforce the air cylinder 202, making the connection between the air cylinder 202 and the air box 201 more stable and reliable, thereby ensuring the stability of the air cylinder 202 during use.

[0028] Two limit rings 207 are fixedly installed on the inner wall of each inflation cylinder 202, and the interior of each set of limit rings 207 is connected to a connecting rod 208 for rotation together. A clockwork spring 209 is fixedly installed on the inner wall of each limit ring 207, and the inner wall of each clockwork spring 209 is fixedly connected to the outer surface of the connecting rod 208. The air inlet end of each inflation pump 205 and the air outlet end of each exhaust pump 206 are fixedly connected with a one-way valve 220, and the top of each one-way valve 220 penetrates the inflation box 201 and extends to the top of the inflation box 201. The one-way valve 220 can prevent the gas from leaking outward through the inflation pump 205 after the inflation pump 205 is inflated, and the one-way valve 220 on the exhaust pump 206 can prevent the outside gas from re-entering the interior of the inflation cylinder 202 after the exhaust pump 206 pumps air outward, thereby ensuring the stability of the inflation cylinder 202 after inflation and exhaust.

[0029] The outer surface of each connecting rod 208 is sleeved with a winding rope 224, and the end of each winding rope 224 away from the connecting rod 208 passes through the rubber telescopic tube 203 and is fixedly connected to the inner wall of the expansion airbag 204. A sealing plate 221 is provided on the side of each inflation box 201 away from the bottom plate 1, and three electric push rods 222 are fixedly connected to the side of each sealing plate 221 close to the inflation box 201, and the end of each electric push rod 222 away from the sealing plate 221 is fixedly connected to the inner wall of the inflation box 201. The thrust provided by the electric push rod 222 can be used to push the sealing plate 221 outward, so as to facilitate the expansion of the rubber telescopic tube 203 and the expansion airbag 204. At the same time, the inflation box 201 can also be closed after the rubber telescopic tube 203 and the expansion airbag 204 are contracted, thereby increasing the safety protection effect of the rubber telescopic tube 203 and the expansion airbag 204.

[0030] A connecting block 210 is fixedly installed on the outer surface of each winding rope 224, and an elastic rope 211 is fixedly installed on the side of each connecting block 210 away from each other, and the end of each elastic rope 211 away from the connecting block 210 is fixedly connected to the inner wall of the inflatable airbag 204, and two limit plates 223 are fixedly installed on the outer surface of each connecting rod 208, and the side of each group of limit plates 223 close to each other is in contact with the outer surface of the winding rope 224. The limit plates 223 can be used to limit the position of the winding rope 224 on the connecting rod 208, so that the winding rope 224 is not easy to be excessively deviated, thereby improving the reliability of the winding rope 224 when in use.

[0031] Working principle: When in use, first connect the air pump 205, the exhaust pump 206 and the electric push rod 222 to the power supply. When the fire fighting robot chassis needs to pass through a deep wading environment to perform dangerous exploration tasks, the power provided by the electric push rod 222 pushes the sealing plate 221 to move outward to open the air box 201. At this time, the suction force provided by the air pump 205 can be used to send the outside air and the air box 201 into the air cylinder 202. Then, as the air pressure inside the air cylinder 202 increases, it will force the rubber telescopic cylinder 203 and the expansion cylinder 201 to move outward. The inflatable airbag 204 expands, thereby forming four airbags outside the bottom plate 1. At this time, when the fire-fighting robot chassis passes through a deeper wading environment, the water-afraid equipment on the chassis will not come into contact with the water, so that the chassis floats on the water surface. The fire-fighting robot chassis cooperates with the inflatable mechanism 2 to increase the passability, and pass through the wading area more safely, which is convenient for the fire-fighting robot to survey the dangerous disaster scene in the wading environment, and further increases the use effect of the chassis of the fire-fighting robot. The suction force of the exhaust pump 206 can make the inflatable airbag 204 and the rubber expansion and contraction The gas inside the cylinder 203 is quickly drawn out, so that the chassis of the fire-fighting robot can quickly return to its original state after leaving the wading environment, preventing the undeflated inflation airbag 204 from affecting the smooth progress of the subsequent fire-fighting robot's reconnaissance mission. Finally, the limit ring 207 is used in conjunction with the spring spring 209. When the inflation airbag 204 and the rubber telescopic cylinder 203 are inflated, the pressure will pull the elastic rope 211 to extend and cooperate with the winding rope 224 to pull the connecting rod 208 to rotate, so that the spring spring 209 accumulates elastic force, and then when the inflation airbag 204 and After the gas inside the rubber telescopic tube 203 is discharged outward, the elastic force accumulated in the clockwork spring 209 and the elastic force of the elastic rope 211 cooperate with the connecting block 210 to pull the inflatable airbag 204 and the rubber telescopic tube 203 back into the inflation box 201, so that they can be quickly prepared for the next use. At the same time, the inflatable airbag 204 and the rubber telescopic tube 203 will not expand outward, preventing the inflatable airbag 204 and the rubber telescopic tube 203 from affecting the movement of the fire-fighting robot chassis, thereby further increasing the smoothness of the movement of the fire-fighting robot chassis.

[0032] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
