Description

Technical Field

[0001] The present invention relates to the technical field of fire-fighting water monitors, and in particular to a fire-fighting water monitor lifting and adjusting device. Background Art

[0002] Fire monitors are firefighting devices that convert pressurized water into energy, ejecting it from the monitor's outlet at high speed, creating a water jet that can extinguish fires at a distance. As society develops, the causes of fires are increasing significantly, and fire situations are becoming increasingly complex. Fire monitors can quickly and efficiently extinguish fires and prevent them from spreading, thus playing a vital role in firefighting.

[0003] In response to the fire environment, many improvements have been made to the existing fire water monitors. Many fire water monitors have achieved automatic lifting and adjustment control through the installed hydraulic devices and the help of electrically driven hydraulic pumps. Firefighters can remotely control the spraying status of the fire water monitor through the console in the water tanker cab, thereby carrying out firefighting operations quickly and labor-savingly in a safe environment.

[0004] However, due to the harsh environment of the fire scene, electronically controlled fire water monitors may face the risk of failure of the electronic control device.

[0033] To make the objectives, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts shall fall within the scope of protection of the present invention.

[0034] Example 1

[0035] Reference Figure 1-9A fire water monitor lifting and adjustment device includes a console 1, a vertical lifting assembly 2, a rotation drive assembly 3 and a water outlet control assembly 4. A fire water monitor 600 is fixedly installed on the top surface of the console 1. The fire water monitor 600 includes a vertical telescopic sleeve 601, a bending sleeve 602 and a spray pipe 603. The bottom of the vertical telescopic sleeve 601 is fixed to the console 1 and connected to the water pump of the water tank truck. The top of the inner tube of the vertical telescopic sleeve 601 is connected to the vertical lifting assembly 2. The vertical lifting assembly 2 controls the extension and shortening of the vertical telescopic sleeve 601 by driving the inner tube of the vertical telescopic sleeve 601 to move up and down.

[0036] The bending sleeve 602 is a U-shaped bending sleeve, one end of the U-shaped bending sleeve 602 is vertically bent and connected to the upper end of the inner tube of the vertical telescopic sleeve 601, and the other end is vertically bent and connected to the injection pipe 603. The rotation drive component 3 is respectively installed at the rotation intersection of the two ends of the bending sleeve 602 and the vertical telescopic sleeve 601 and the injection pipe 603 to control the up and down and left and right swings of the injection pipe 603 as needed. The water outlet control component 4 is installed at the water outlet of the injection pipe 603 to control the size of the water flow sprayed from the injection pipe 603.

[0037] The console 1 includes a fixed base 11 with a hollow interior, and the vertical lifting assembly 2 includes a hydraulic cylinder 21, a hydraulic rod 22, a vertical hydraulic plug 23 and a threaded disk 24. The hydraulic cylinder 21 is installed inside the fixed base 11, and the hydraulic cylinder 21 is connected to the hydraulic rod 22 that extends vertically upward from the fixed base 11 and is connected to the upper end of the inner tube of the vertical telescopic sleeve 601. When all the hydraulic liquid in the hydraulic cylinder 21 flows into the hydraulic rod 22, the hydraulic rod 22 will extend to its longest to stretch the vertical telescopic sleeve 601 to its longest.

[0038] The upper part of the hydraulic cylinder 21 is a hydraulic chamber 201, and the lower part is a threaded chamber 202. A vertical hydraulic plug 23 is provided in the hydraulic cylinder 21. The upper half of the vertical hydraulic plug 23 is inserted into the hydraulic chamber 201, and the lower half is connected to the rotating shaft of the threaded disk 24. The inner wall of the threaded chamber 202 has a thread that matches the outer peripheral wall of the threaded disk 24. When the threaded disk 24 is driven and rotates axially in the threaded chamber 202, it can drive the vertical hydraulic plug 23 to move up and down in the hydraulic chamber 201, thereby driving the vertical telescopic sleeve 601 to telescope and adjust.

[0039] The center of the bottom of the threaded disk 24 is provided with a multi-faceted telescopic column 25, which is composed of multiple hollow multi-faceted cylindrical tubes that are sequentially connected. The top multi-faceted cylindrical tube is installed at the center of the bottom of the threaded disk 24. A drive motor 26 is installed below the multi-faceted telescopic column 25. Each multi-faceted cylindrical tube of the multi-faceted telescopic column 25 is freely hanging under the action of gravity and docking with the shaft of the drive motor 26. The bottom end of the multi-faceted cylindrical tube at the bottom of the multi-faceted telescopic column 25 has a multi-faceted groove 203, and the shaft of the drive motor 26 The diameter is smaller than the diameter of the inscribed circle of the polygonal groove 203. The outer peripheral wall of the driving motor 26 shaft has a controlled and retractable slot head 27. When the driving motor 26 is running, the slot head 27 is pushed out of the outer peripheral wall of the shaft and inserted into the various edge corners of the polygonal groove 203, so that the cylindrical driving motor 26 shaft can drive the polygonal telescopic column 25 to rotate axially. When the driving motor 26 stops, the slot head 27 is retracted into the shaft. At this time, the polygonal telescopic column 25 can freely rotate axially relative to the driving motor 26 shaft.

[0040] The rotary drive assembly 3 includes an outer sleeve 31, an inner rotating tube 32 and a drive setting tube 33. The outer sleeve 31 of the rotary drive assembly 3 installed at the connection between the U-shaped bent sleeve 602 and the vertical telescopic sleeve 601 is fixed to the top of the vertical telescopic sleeve 601, and the inner rotating tube 32 is fixedly connected and communicated with the U-shaped bent sleeve 602 so that the fire water flow can smoothly enter the U-shaped bent sleeve 602. When the inner rotating tube 32 rotates axially in the outer sleeve 31, the water supply pipe in the vertical telescopic sleeve 601 and the U-shaped bent sleeve 602 will also rotate together.

[0041] The outer sleeve 31 of the rotating drive assembly 3 at the connection between the U-shaped bent sleeve 602 and the injection pipe 603 is fixed to the U-shaped bent sleeve 602, and the inner rotating pipe 32 is fixedly connected and communicated with the injection pipe 603, so that the fire water flowing into the U-shaped bent sleeve 602 can smoothly enter the outer sleeve 31 and finally be ejected. When the inner rotating pipe 32 rotates axially in the outer sleeve 31, it will drive the injection pipe 603 connected thereto to rotate and swing up and down.

[0042] An outer ring gear 34 is provided on the outer peripheral wall of the inner rotating tube 32, and an intermediate transmission member is provided in the outer sleeve 31. One end of the intermediate transmission member is vertically meshed with the outer ring gear 34, and the other end extends into the driving setting cylinder 33 and is connected with the helical gear of the transmission long rod 35 therein. When the transmission long rod 35 is driven to rotate axially, it can drive the intermediate transmission member to rotate axially, and finally drive the inner rotating tube 32 fixed with the outer ring gear 34 to rotate axially.

[0043] A rotary motor 36 is installed at one end of the transmission rod 35 away from the intermediate transmission member, and a gap is formed between the rotating shaft of the rotary motor 36 and the transmission rod 35. The transmission rod 35 has a docking slot 301 facing the rotating shaft of the rotary motor 36. The rotating shaft of the rotary motor 36 has a docking block that can protrude toward the transmission rod 35. The docking block is a polygonal columnar block, and the docking slot 301 is a polygonal groove that can correspond to it. When the rotary motor 36 is closed, the docking block retracts into the rotating shaft. At this time, the transmission rod 35 can freely rotate axially relative to the stationary rotating shaft of the rotary motor 36. When working, the rotary motor 36 drives the docking block to pass through the gap with the transmission rod 35 and insert into the docking slot 301 for cooperation. Then, the rotary motor 36 drives the transmission rod 35 to rotate axially by driving the rotating shaft to rotate axially.

[0044] The water outlet control component 4 includes a hydraulic arm 41, a hydraulic pump 42 and an opening and closing door 43. When powered on, the hydraulic pump 42 can control the opening and closing degree of the opening and closing door 43 hinged to the hydraulic arm 41 by injecting or extracting hydraulic fluid into or out of the hydraulic arm 41, thereby controlling the size of the water flow ejected from the injection pipe 603.

[0045] Example 2

[0046] Reference Figure 1-9 The difference between this embodiment and embodiment 1 is that the console 1 includes a fixed base 11, a pull-out drawer rack 12 and a work platform 13, the fire water monitor 600 is fixedly installed on the fixed base 11, the pull-out drawer rack 12 can be stored in the internal hollow fixed base 11, and the work platform 13 is connected to the guide rail 14 vertically installed on the straight panel of the pull-out drawer rack 12 through a rotating shaft clamp 17, one end of the rotating shaft clamp 17 is clamped with the guide rail 14 track, and the other end is connected to the rotating shaft of the outer wall of the work platform 13, when the pull-out drawer rack 12 is stored in the fixed base 11, the work platform 13 is in an upright state to avoid occupying the space set by the hydraulic cylinder 21, and after the pull-out drawer rack 12 is pulled out, the work platform 13 falls and flattens under the action of its own gravity for firefighters to stand and step on.

[0047] A control adapter 15 is installed in the fixed base 11. The control adapter 15 is electrically connected to the controller to receive control operation instructions made by firefighters. The control adapter 15 is electrically connected to the drive motor 26, the rotating motor 36, and the hydraulic pump 42 to control the operation of the vertical lifting component 2, the rotating drive component 3 and the water outlet regulation component 4 according to the received control signal. It is worth mentioning that the control adapter 15 is connected to the rotating motor 36 through a sleeve pipe 5. The sleeve pipe 5 has two layers, an inner layer and an outer layer. The connection circuit of the control adapter 15 is arranged on the outer layer of the sleeve pipe 5 and is connected to the rotating motor 36. The inner layer of the sleeve pipe 5 is filled with hydraulic fluid.

[0048] The working platform 13 is equipped with two sets of pedal control systems 37. One set of pedal control systems 37 includes two sets of pedals 371, a switching block 372, a lower edge part 373, a return spring 374 and a tooth shift block 375. The upper end of the lower edge part 373 passes through the top plate of the working platform 13 and is equipped with a pedal 371. The switching block 372 is installed on the pedal 371. The return spring 374 is installed at the bottom of the lower edge part 373 so that the pedal 371 and the lower edge part 373 can be smoothly restored to their original positions after the lower edge part 373 on which the pedal 371 is installed is stepped down and the downward pressure is removed. The lower edge part 373 has a hydraulic chamber 302 and a transverse limit groove 303 connected to the hydraulic chamber 302. The tooth shift block 375 is arranged in the transverse limit groove 303.

[0049] One end of the hydraulic tank 302 is connected to the pedal 371 upward, and the other end is connected to the transverse limit groove 303. The tooth shift block 375 is connected to the mobile piston inserted into the connection between the hydraulic tank 302 and the transverse limit groove 303. The switching block 372 is set at the switching groove 304 set at the top of the pedal 371. The bottom of the switching block 372 is installed with a mobile piston inserted into the connection between the hydraulic tank 302 and the switching groove 304. The switching block 372 is connected to the bottom wall of the switching groove 304 through a reset member. The tooth shift block 375 is connected to the bottom wall of the switching groove 304 through a reset member. The positioning member is connected to the side wall of the transverse limit groove 303. Under normal circumstances, the reset member will push up the switching block 372 and partially protrude from the switching groove 304. When the firefighter steps on the pedal 371 and the switching block 372 arranged thereon, the moving piston connected to the switching block 372 will move downward and squeeze the hydraulic fluid in the hydraulic tank 302 to the bottom, thereby pushing the tooth shift block 375 out of the transverse limit groove 303. After the firefighter removes the downward force, the reset member will push the switching block 372 back to its original position, and the tooth shift block 375 will also return to its original position.

[0050] Two sets of hydraulic matching systems 38 are provided in the fixed base 11. The hydraulic matching systems 38 include a hydraulic cross pipe 381, a threaded push rod 382, a sleeve gear ring 383 and a support frame 384. The hydraulic cross pipe 381 filled with hydraulic fluid is installed horizontally in the fixed base 11. A hydraulic plug is provided at one end of the threaded push rod 382 and is inserted into the hydraulic cross pipe 381. The threaded push rod 382 with a threaded surface extends from the hydraulic cross pipe 381. The sleeve gear ring 383 is threadedly sleeved and installed on the outside of the threaded push rod 382. The outer peripheral wall of the sleeve gear ring 383 has teeth and circular grooves on both sides. One end of the support bracket 384 is fixedly installed on the inner wall of the fixed base 11, and the other end can be rotatably inserted into the circular groove set on the side of the sleeve gear ring 383, thereby limiting the sleeve gear ring 383 to a specified spatial position and being able to freely rotate axially around the threaded push rod 382. When the sleeve gear ring 383 with a fixed spatial position is axially rotated, it can drive the threaded push rod 382 to move horizontally, thereby pushing out or sucking back the hydraulic fluid in the hydraulic cross pipe 381.

[0051] A spiral groove 305 is provided on the outer peripheral wall of the transmission long rod 35, and a hydraulic linkage system 39 is provided in the driving setting cylinder 33. The hydraulic linkage system 39 includes a hydraulic telescopic column 391, a sleeve ring 392 and an adapter seat 393. The sleeve ring 392 is sleeved on the outside of the transmission long rod 35, and the sleeve ring 392 has an inward channel 306 connected to the hydraulic telescopic column 391. The inward channel 306 leads toward the transmission long rod 35. A shift plug 394 is provided in the inward channel 306. Under normal circumstances, the shift plug 394 is pushed toward the outer wall of the transmission long rod 35 by the elastic member. When the hydraulic telescopic column 391 is short, the position of the shift plug 394 cannot match the spiral groove 305, thereby not affecting the rotation of the transmission long rod 35 when driven by the rotating motor 36.

[0052] The hydraulic telescopic column 391 is connected to the adapter seat 393, and the adapter seat 393 is connected to the hydraulic cross pipe 381 through the inner tube filled with hydraulic fluid through the sleeve pipe 5, so that when the threaded push rod 382 moves horizontally, the hydraulic fluid in the hydraulic cross pipe 381 will eventually be pushed into or sucked out of the hydraulic telescopic column 391.

[0053] The two tooth shift blocks 375 of a set of the pedal control system 37 are respectively arranged on both sides of the peripheral wall of the sleeve gear ring 383. When the firefighter steps on the pedal 371 on one side, the corresponding tooth shift block 375 will move out of the transverse limit groove 303 and engage with the sleeve gear ring 383. Then the tooth shift block 375 and the lower edge member 373 move downward together and drive the sleeve gear ring 383 to rotate, thereby driving the threaded push rod 382 to move horizontally. After the firefighter steps on the lower edge member 373 to the lowest point, the foot When the tooth shift block 375 is disengaged from the pedal 371, the tooth shift block 375 will retract into the transverse limit groove 303 and release the engagement with the socket gear ring 383, so that the upward tooth shift block 375 will not drive the socket gear ring 383 to rotate. Firefighters can cyclically step on two different pedals 371 of a set of pedal control systems 37 as needed to drive the socket gear ring 383 to rotate clockwise or counterclockwise, thereby driving the threaded push rod 382 to move the hydraulic plug inserted into the hydraulic cross pipe 381.

[0054] When the rotating motor 36 fails to work, the firefighter can step on the pedal 371 to push the hydraulic fluid in the hydraulic cross tube 381 into the hydraulic telescopic column 391 to extend the hydraulic telescopic column 391. At the same time, the hydraulic fluid in the hydraulic telescopic column 391 will also enter the inner channel 306 and push the shift plug 394 toward the outer wall of the transmission long rod 35 until the hydraulic telescopic column 391 extends to a certain position and the shift plug 394 corresponds to the spiral groove 305. At this time, the shift plug 394 will extend into the spiral groove 305 and be maintained under the action of hydraulic pressure. At this time, when the firefighter continues to drive the hydraulic fluid in the hydraulic cross tube 381 to push in and extend the hydraulic telescopic column 391, the shift plug 394 that moves along with the hydraulic telescopic column 391 can cooperate with the spiral extension. The spiral groove 305 drives the transmission long rod 35 to rotate. It is worth mentioning that when the hydraulic fluid in the hydraulic telescopic column 391 is extracted by the hydraulic cross tube 381 and the hydraulic telescopic column 391 is shortened, the elastic force provided by the elastic member can still keep the shift plug 394 in the spiral groove 305, so that the hydraulic telescopic column 391 can still drive the transmission long rod 35 to rotate with the help of the shift plug 394 during the shortening process. After the hydraulic telescopic column 391 is retracted to the point where the shift plug 394 reaches the end of the spiral groove 305, it will prevent the hydraulic telescopic column 391 from continuing to retract. At this time, the pressure of the hydraulic fluid sucked back by the hydraulic cross tube 381 will force the shift plug 394 to retract into the inner channel 306, overcoming the elastic force of the elastic member, so that the hydraulic telescopic column 391 continues to retract.

[0055] The locking block 376 is inserted into the locking slot 307 to keep the switch block 372 in the switch groove 304.

[0056] It can be understood that the two sets of the pedal control system 37, the hydraulic coordination system 38 and the hydraulic linkage system 39 respectively control the two sets of rotary drive components 3. After the working platform 13 is pulled out and laid flat, the firefighters can manually control the operating status of the fire water cannon 600 by stepping on different pedals 371.

[0057] Example 3

[0058] Reference Figure 1-9 The difference between this embodiment and embodiment 2 is that a group of hydraulic pedaling members 28 are installed on the upper surface of the working platform 13, and each of the hydraulic pedaling members 28 includes a hydraulic telescopic tube that can automatically rebound after being pressed down due to a spring arranged inside. The hydraulic fluid in the hydraulic telescopic tube is connected to the driving hydraulic member 29, and the driving hydraulic member 29 includes a connecting tube 291, a hollow piston 292, a mating head 293 and an engaging block 294. The connecting tube 291 is connected to the hydraulic telescopic tube of the hydraulic pedaling member 28 through a hose, one end of the hollow piston 292 is inserted into the connecting tube 291, and the other end extends out of the connecting tube 291 and is connected to the mating head 293, and the engaging block 294 is installed on the mating head 293, and the side of the meshing block 294 with teeth extends out from the mating head 293.

[0059] A hydraulic cut-off pipe 295 is provided in the mating head 293, and a short plug 296 inserted into the hydraulic cut-off pipe 295 is installed on the side of the engaging block 294 away from the tooth setting. The hydraulic liquid in the connecting pipe 291 flows through the pipeline formed by the hollow inside of the hollow piston 292 to the hydraulic cut-off pipe 295 connected to the internal cavity of the hollow piston 292. The engaging block 294 is arranged near the tooth ring provided on the outer peripheral surface of the bottom end of the polygonal telescopic column 25. When the hydraulic pedal 28 is not stepped on, the hydraulic liquid in the hydraulic cut-off pipe 295 causes the engaging block 294 and the tooth ring to be spaced apart and unable to engage.

[0060] When the firefighter steps on the hydraulic pedal 28, the hydraulic fluid in the hydraulic telescopic tube will be squeezed into the connecting tube 291 and flow into the inner cavity of the hollow piston 292, so as to push out the short plug 296 in the hydraulic cut-off tube 295 and move the engaging block 294 toward the toothed ring until it engages with it. After that, the hydraulic pedal 28 is further stepped on to continue to deliver the hydraulic fluid to the connecting tube 291, so as to push out the hollow piston 292 installed with the mating head 293 as a whole, so as to make the engaging block 294 installed in the mating ring 295 engage with the engaging block 294. The engaging block 294 of the head 293 drives the polygonal telescopic column 25 to rotate. After the firefighter no longer steps on the hydraulic pedal 28, the hydraulic pedal 28 automatically springs up and first extracts the hydraulic fluid in the hydraulic cut-off tube 295 to disengage the engaging block 294 from the tooth ring. During the subsequent springing process of the hydraulic pedal 28, the hydraulic fluid in the connecting tube 291 is gradually extracted to restore the mating head 293 and the engaging block 294 to their original positions so that the polygonal telescopic column 25 can be driven to rotate again.

[0061] The inner cavity of the hydraulic arm 41 is connected to the hand-turned hydraulic component 16 installed on the working platform 13 through a transmission pipe. The hand-turned hydraulic component connection 16 includes a stand plate 161, a hydraulic seat 162 and a hand-turned wheel 163. The stand plate 161 is vertically installed on the surface of the working platform 13, and the hydraulic seat 162 is fixedly installed on the surface of the stand plate 161. The hydraulic seat 162 is filled with hydraulic fluid and has a hydraulic piston extending to the outside. The hand-turned wheel 163 is connected to the hydraulic piston.

[0062] The hand wheel 163 is connected to the stand plate 161 through a screw barrel. When the firefighter stands on the work platform 13, he can grasp the handle of the hand wheel 163 to drive the hand wheel 163 to rotate, and then drive the hand wheel 163 to move toward or away from the stand plate 161, thereby driving the hydraulic piston connected to it to be pressed into the hydraulic seat 162 or moved out of the hydraulic seat 162, thereby controlling the extension and retraction of the hydraulic arm 41 connected to the hydraulic seat 162.
