Description

Technical Field

[0001] The utility model relates to a supporting device, in particular to a supporting component for a high-pressure fire fighting cannon, belonging to the technical field of high-pressure fire fighting cannon support. Background Technique

[0002] High-pressure fire fighting water cannons have become the main fire fighting tools. The high-pressure water sprayed by the fire fighting water cannons has the advantages of long range and high pressure, and can extinguish fires on higher floors. However, since the fire fighting cannons are all connected to the water supply pipe through the tail, when the fire fighting cannon sprays in different directions, it is necessary to rotate the cannon head, which will cause the fire fighting hose at the connection between the cannon tube and the water supply pipe to bend, affecting the water flow speed.

[0003] After retrieval, Chinese Patent No. CN207871332U discloses a supporting component for a high-pressure fire fighting cannon. An auxiliary supporting mechanism is installed on the fire fighting vehicle body, which can fix the pipeline of the fire fighting hose, so that the connection between the water cannon and the liquid pipe always remains straight. Even if the rotating disk rotates, the fire fighting hose rotates together, and the liquid pipe will not be bent due to rotation, affecting the water pressure. However, in the above patent product, the fire fighting hose passes through the clamp, and the fire fighting hose is in an overhead state, so the hose can be prevented from bending. In actual use, due to the continuous gushing of high-pressure water flow, the impact force on the clamp position is relatively large, and the clamp is prone to loosen due to force. At the same time, when the water flow is small, the water pipe between the clamp and the high-pressure fire fighting cannon is prone to folding, affecting the subsequent spraying efficiency.

[0011] The beneficial effects of the present utility model are as follows: In the above-mentioned patented product, the fire hose passes through the clamp, and the fire hose is in an overhead state, so it can avoid the hose from being bent. During actual use, due to the continuous gushing of high-pressure water flow, the impact force on the clamp position is relatively large, and the clamp is prone to being loosened by the force. At the same time, when the water flow is small, the water pipe between the clamp and the high-pressure fire cannon is prone to folding, affecting the subsequent spraying efficiency. The present utility model adds an arc-shaped plate at one end of the base for connecting the high-pressure fire cannon.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0018] The technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0019] Please refer to Figures 1-5 As shown, a support assembly for a high-pressure fire fighting cannon includes a connection base 1. On one side of the top end of the connection base 1, there is a support device 3. The support device 3 includes a second telescopic cylinder 301, a fixed clamp 302, a fixed collar 303, a rotating shaft 304, a connection block 305, a fixed screw 306, a hexagonal nut 307, a resisting block 308, a return spring 309, a support column 310, an arc-shaped plate 311, a connection ring 312, and a limit screw 313. On one side of the top end of the connection base 1, there is a second telescopic cylinder 301. The execution end of the second telescopic cylinder 301 is connected with a fixed clamp 302. One end of the fixed clamp 302 is provided with a rotating shaft 304. On the side of the rotating shaft 304 away from the fixed clamp 302, there is a fixed collar 303. Connection blocks 305 are provided at the ends of the fixed collar 303 and the fixed clamp 302 away from the rotating shaft 304. The connection blocks 305 are provided with fixed screws 306 in a matching manner. The bottom end of the fixed screw 306 is provided with a hexagonal nut 307. Resisting blocks 308 are arranged inside the fixed clamp 302 and the fixed collar 303. Return springs 309 are arranged on the sides of the resisting blocks 308 close to the fixed clamp 302 and the fixed collar 303. On both sides of one end of the connection base 1 close to the second telescopic cylinder 301, there are support columns 310. Between the top ends of the two support columns 310, there is an arc-shaped plate 311. A plurality of connection rings 312 are arranged at equal intervals inside the arc-shaped plate 311. A limit screw 313 is arranged between the arc-shaped plate 311 and the support column 310.

[0020] The bottom end of the fixed clamp 302 is movably clamped with the second telescopic cylinder 301. The fixed clamp 302 is fixedly connected with the rotating shaft 304. The fixed collar 303 is hinged with the rotating shaft 304.

[0021] According to the above embodiments, it should be noted that: The connection base 1 is arranged on the fire truck. When using the high-pressure fire fighting cannon main body 204, the water pipe 4 is drawn out, the joint 401 is connected and fixed to the tail end of the high-pressure fire fighting cannon main body 204, and then the snap ring 402 of the water pipe 4 is placed on the fixed clamp 302. The fixed collar 303 is manually rotated around the rotating shaft 304 to connect the two connection blocks 305. The fixed screw 306 is screwed in, and then the hexagonal nut 307 is screwed into the bottom end of the fixed screw 306 to fix and stabilize both the upper and lower parts of the connection block 306.

[0022] When the fixed clamp 302 is connected to the fixed collar 304, the abutting block 308 abuts against the outer side of the snap ring 402, and the return spring 309 is compressed. After the fixed screw 306 is installed, the force of the return spring 309 resetting gives the abutting block 308 to more firmly abut against the snap ring 402 of the water pipe 4, avoiding the water pipe 4 from vibrating when high-pressure water flows through, resulting in insecure fixation.

[0023] After the water pipe 4 is fixed to the fixed clamp 302, according to the height of the water pipe 4, the position of the arc-shaped plate 311 is adjusted. After adjusting to the appropriate position, the limit screw 313 is screwed in for fixation. At the same time, the fixing rope 404 on the water pipe 4 is passed through the connecting ring 312 for fixation, and the water pipe 4 is elevated, so that when the water flow is small, the water pipe 4 can be lifted to prevent it from being bent.

[0024] Please refer to Figures 1-5 As shown in the figure, a support assembly for a high-pressure fire fighting cannon includes a driving turntable 2 provided at one end of the top of the connecting base 1 away from the second telescopic cylinder 301. A connecting column 202 is provided on the top of the driving turntable 2 and close to one side of the second telescopic cylinder 301. A first telescopic cylinder 201 is provided on the side of the connecting column 202 away from the second telescopic cylinder 301 and at the top of the driving turntable 2. A fixing ring 203 is provided at the top of the connecting column 202. A high-pressure fire fighting cannon main body 204 is provided in the middle of the fixing ring 203. The execution end of the first telescopic cylinder 201 is hinged to the bottom end of the high-pressure fire fighting cannon main body 204, and the bottom end of the fixing ring 203 is hinged to the connecting column 202.

[0025] The high-pressure fire fighting cannon main body 204 is equipped with a water pipe 4. One end of the water pipe 4 is provided with a joint 401. A snap ring 402 is provided near the joint 401 of the water pipe 4. A fixing rope 404 is provided on the outer side of the water pipe 4 on the side of the snap ring 402 away from the joint 401. A folding bellows 403 is provided between the joint 401 and the snap ring 402 of the water pipe 4.

[0026] According to the above embodiments, it should be noted that: according to the actual situation, the execution height of the first telescopic cylinder 201 can be adjusted to adjust the elevation angle of the high-pressure fire fighting cannon main body 204. The folding bellows 403 provided in the water pipe 5 at this position can be bent and folded along with the elevation of the high-pressure fire fighting cannon main body 204 to avoid direct bending.

[0027] A driving motor is provided at the bottom end of the driving turntable 2, which can drive the driving turntable 2 to rotate horizontally and change the angle of the high-pressure fire fighting cannon main body 204.

[0028] In summary, the usage process of this device is as follows: The connecting base 1 is installed on the fire truck. When using the high-pressure fire fighting cannon main body 204, pull out the water pipe 4, connect and fix the joint 401 to the tail end of the high-pressure fire fighting cannon main body 204, then place the snap ring 402 of the water pipe 4 on the fixed clamp 302, manually rotate the fixed collar 303 around the rotating shaft 304 to connect the two connecting blocks 305, screw in the fixed screw 306, and then screw the hexagonal nut 307 into the bottom end of the fixed screw 306 to fix and stabilize both the upper and lower parts of the connecting block 306.

[0029] When the fixed clamp 302 is connected to the fixed collar 304, the abutting block 308 abuts against the outer side of the snap ring 402, and the return spring 309 is compressed. After the fixed screw 306 is installed, the force of the return spring 309 resetting is applied to the abutting block 308 to make it more forcefully abut against the snap ring 402 of the water pipe 4, preventing the water pipe 4 from vibrating due to high-pressure water flow and resulting in loose fixation.

[0030] After the water pipe 4 is fixed to the fixed clamp 302, adjust the position of the arc-shaped plate 311 according to the height of the water pipe 4. After adjusting to the appropriate position, screw in the limit screw 313 for fixation. At the same time, pass the fixing rope 404 on the water pipe 4 through the connecting ring 312 for fixation, and lift the water pipe 4 off the ground so that when the water flow is small, the water pipe 4 can be lifted to prevent it from bending.

[0031] Adjust the execution height of the first telescopic cylinder 201 according to the actual situation, which can adjust the elevation angle of the high-pressure fire fighting cannon main body 204. The folding bellows 403 provided on the water pipe 5 at this position can be bent and folded as the high-pressure fire fighting cannon main body 204 is lifted, avoiding direct bending.

[0032] A driving motor is provided at the bottom end of the driving turntable 2, which can drive the driving turntable 2 to rotate horizontally, driving the angle of the high-pressure fire fighting cannon main body 204 to change.
