Description

Technical Field

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

[0002] Fire water monitor is a firefighting equipment that converts pressurized water into energy and sprays it out from the water outlet of the monitor head at a high speed to form a water jet, thereby extinguishing fires at a certain distance. With the development of society, the factors that lead to fires have also increased significantly, and the fire situation has become more and more complicated. Fire water monitors can quickly and efficiently extinguish fires and prevent the spread of fires, so they play an important role in firefighting.

[0003] In response to the fire environment, many improvements have been made to the existing fire water cannons. Many fire water cannons 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 cannon through the control console in the water tanker cab, thereby carrying out firefighting operations quickly and labor-savingly in a safe environment.

DETAILED DESCRIPTION

[0033] In order to make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the technical solution in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are 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 creative work are within the scope of protection of the present invention.

[0034] Example 1

[0035] Reference Figure 1-9A fire-fighting water monitor lifting and adjusting device comprises a control console 1, a vertical lifting assembly 2, a rotating drive assembly 3 and a water outlet regulating assembly 4. A fire-fighting water monitor 600 is fixedly installed on the top surface of the control console 1. The fire-fighting water monitor 600 comprises 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 control console 1 and connected to a water pump of a water tank truck. The top end of an 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 rotating drive component 3 is respectively installed at the two ends of the bending sleeve 602 and the rotating intersection with 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 regulating 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 control 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 which 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 fluid in the hydraulic cylinder 21 flows into the hydraulic rod 22, the hydraulic rod 22 will extend to its longest position to stretch the vertical telescopic sleeve 601 to its longest position.

[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 arranged 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] A multi-faceted telescopic column 25 is installed at the bottom center of the threaded disk 24. The multi-faceted telescopic column 25 is composed of multiple hollow multi-faceted cylindrical tubes that are sequentially connected. The uppermost multi-faceted cylindrical tube is installed at the bottom center of the threaded disk 24. A driving motor 26 is installed below the multi-faceted telescopic column 25. Each multi-faceted cylindrical tube of the multi-faceted telescopic column 25 freely hangs down under the action of gravity and docks with the rotating shaft of the driving 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. The rotating shaft of the driving 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 shrinks into the shaft, and 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 bending sleeve 602 and the vertical telescopic sleeve 601 is fixed to the top of the vertical telescopic sleeve 601, while the inner rotating tube 32 is fixedly connected and communicated with the U-shaped bending sleeve 602 so that the fire water flow can smoothly enter the U-shaped bending 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 bending 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 flow flowing into the U-shaped bent sleeve 602 can smoothly enter the outer sleeve 31 and finally be sprayed out. 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 tube 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 fixedly mounted 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 rotation axis of the rotary motor 36 and the transmission rod 35. A docking slot 301 is formed on the transmission rod 35 facing the rotation axis of the rotary motor 36. The rotation axis 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 thereto. When the rotary motor 36 is closed, the docking block shrinks into the rotation axis. At this time, the transmission rod 35 can freely rotate axially relative to the stationary rotation axis 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 rotation axis 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 the hydraulic arm 41, thereby controlling the size of the water flow sprayed from the injection pipe 603.

[0045] Example 2

[0046] Reference Figure 1-9 The difference between this embodiment and embodiment 1 is that the control console 1 includes a fixed base 11, a pull-out drawer rack 12 and a work platform 13, the fire water cannon 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, the work platform 13 is connected to the guide rail 14 vertically installed on the straight enclosure plate 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 outer peripheral wall rotating shaft 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 tube 5. The sleeve tube 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 tube 5 and is connected to the rotating motor 36. The inner layer of the sleeve tube 5 is filled with hydraulic fluid.

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

[0049] One end of the hydraulic chamber 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 movable piston inserted into the connection between the hydraulic chamber 302 and the transverse limit groove 303. The switching block 372 is arranged at the switching groove 304 arranged at the top of the pedal 371. The bottom of the switching block 372 is installed with a movable piston inserted into the connection between the hydraulic chamber 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 movable piston connected to the switching block 372 will move downward and squeeze the hydraulic fluid in the hydraulic chamber 302 to the lower part, thereby pushing the tooth shifting block 375 to the outside of the transverse limit groove 303. After the firefighter removes the downward force, the reset member will push the switching block 372 up to its original position again, and the tooth shifting block 375 will also return to its original position.

[0050] Two sets of hydraulic matching systems 38 are arranged in the fixed base 11, and the hydraulic matching system 38 includes 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, and a hydraulic plug is arranged at one end of the threaded push rod 382 and inserted into the hydraulic cross pipe 381. The threaded push rod 382 with threads on the surface extends out from the hydraulic cross pipe 381, and 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 frame 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 tube 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 inner channel 306 connected with the hydraulic telescopic column 391. The inner channel 306 leads to the transmission long rod 35. A shift plug 394 is provided in the inner channel 306. Under normal circumstances, the shift plug 394 is pushed toward the outer wall of the transmission long rod 35 by an 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 tube 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 shifting blocks 375 of the pedal control system 37 are respectively arranged on both sides of the peripheral wall of the sleeve tooth ring 383. When the firefighter steps on the pedal 371 on one side, the corresponding tooth shifting block 375 will move out of the transverse limit groove 303 and mesh with the sleeve tooth ring 383. Then the tooth shifting block 375 moves downward together with the lower edge member 373 and drives the sleeve tooth 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, his foot When the part is disengaged from the pedal 371, the gear 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 moving gear shift block 375 will not drive the socket gear ring 383 to rotate. The firefighter can cyclically step on two different pedals 371 of a pedal control system 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 to push the shift plug 394 toward the outer wall of the transmission long rod 35, until the hydraulic telescopic column 391 is extended to a certain position and the shift plug 394 just 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 overcome the elastic force of the elastic member and retract it into the channel 306, so that the hydraulic telescopic column 391 continues to retract.

[0055] Preferably, a locking slot 307 is provided on the side wall of the switching groove 304, and a locking plug 376 that can be moved into the locking slot 307 is provided at the bottom of the switching block 372. The top of the reset member arranged at the switching groove 304 is connected to the sliding rail of the switching block 372. The top surface of the switching block 372 is rough. After the firefighter steps the switching block 372 into the switching groove 304, the horizontal position of the locking plug 376 corresponds to the locking slot 307. At this time, the firefighter can use the friction force between the sole and the top surface of the switching block 372 to push the switching block 372 as a whole in the setting direction of the locking slot 307, so that the locking plug 376 is inserted into the locking slot 307 and the switching block 372 is kept in the switching groove 304. In this way, the tooth shifting block 375 will always be engaged with the sleeve gear ring 383, and when the pedal control system 37 is stepped on and moved up and down, it can drive the threaded push rod 382 to move back and forth, thereby driving the inner rotating tube 32 to swing back and forth.

[0056] It can be understood that the two groups 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 pedal parts 28 are installed on the upper surface of the working platform 13, and each of the hydraulic pedal parts 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 part 29, and the driving hydraulic part 29 includes a connecting tube 291, a hollow piston 292, a matching head 293 and an engaging block 294. The connecting tube 291 is connected to the hydraulic telescopic tube of the hydraulic pedal part 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 matching head 293. The engaging block 294 is installed on the matching head 293, and the side of the engaging block 294 with teeth extends out from the matching head 293.

[0059] A hydraulic cut-off tube 295 is arranged in the mating head 293, and a short plug 296 inserted into the hydraulic cut-off tube 295 is installed on the side of the engagement block 294 away from the tooth setting. The hydraulic liquid in the connecting tube 291 flows to the hydraulic cut-off tube 295 connected to the internal cavity of the hollow piston 292 through a pipeline formed by the hollow inside of the hollow piston 292. The engagement block 294 is arranged close to the tooth ring arranged on the outer peripheral surface of the bottom end of the multi-faceted telescopic column 25. When the hydraulic pedal 28 is not stepped on, the hydraulic liquid in the hydraulic cut-off tube 295 causes the engagement 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 to 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 meshing block 294 toward the toothed ring until it meshes with it. After that, the hydraulic pedal 28 is continuously stepped on and the hydraulic fluid is continuously transported 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 meshing block 294 installed in the mating ring 295 move toward the toothed ring 294 until it meshes with the toothed ring 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 draws out 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 drawn out to restore the mating head 293 and the engaging block 294 to their original positions so as to be able to drive the polygonal telescopic column 25 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 frame plate 161, a hydraulic seat 162 and a hand-turned wheel 163. The frame 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 frame plate 161. The hydraulic seat 162 is filled with hydraulic fluid and has a hydraulic piston protruding to the outside. The hand-turned wheel 163 is connected to the hydraulic piston.

[0062] The hand wheel 163 is connected to the erecting plate 161 through a screw barrel. When the firefighter stands on the working 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 erecting plate 161, thereby driving the hydraulic piston connected thereto 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.
