Description

Technical Field

[0001] This utility model relates to the field of fire truck equipment technology, specifically to the structure of a water tank for a fire truck. Background Technology

[0002] The water tanker is a key component of a fire truck, primarily used to store firefighting water. It is typically made of corrosion-resistant steel or composite materials, possessing excellent sealing and pressure resistance, and can continuously supply water to firefighting equipment during fire rescue operations.

[0003] Utility model patent CN221491294U discloses an integrated forest fire truck water tank. This integrated forest fire truck water tank includes a frame, on which the water tank body is fixedly mounted via a fixing assembly. A climbing frame assembly is movably mounted on the top right side of the frame. The climbing frame assembly includes a main climbing ladder, with pads on both sides of the bottom of the main climbing ladder. Fastening bolts are inserted into threaded holes on the surface of the pads, and the ends of the fastening bolts are inserted into a slider via threaded holes. The slider is embedded in a groove on the side of the frame. By moving the slider within the groove on the top side of the water tank body, the position of the main climbing ladder can be changed. Simultaneously, a control limit block of the auxiliary climbing ladder slides within a guide groove on the side of the main climbing ladder during downward movement. This allows for convenient and independent adjustment of the position of the main climbing ladder and the movable components, enabling them to adapt to the height of the frame and the needs of firefighters.

[0004] The integrated forest fire truck water tank requires turning a knob by twisting a locking block to retract the threaded shaft, and then using tools to pull the water tank body off the frame. The disassembly process relies on tools and is cumbersome. In emergency situations such as fires, it is difficult to quickly load, unload and transfer the water tank, which is not conducive to flexibly responding to emergencies. In view of this, we propose a water tank body structure for fire trucks. Utility Model Content

[0005] The purpose of this utility model is to provide a water tank body structure for fire trucks to solve the problem of inconvenient loading, unloading and transfer of water tanks mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] The water tank structure for a fire truck includes a tank body mounted on a vehicle frame. A pair of symmetrically distributed protrusions are provided on the left and right end faces of the tank body. Each protrusion contains a moving component for individually moving the tank body. The moving component includes a support leg fitted inside the protrusion and capable of moving up and down along the protrusion, a rotary motor mounted on the top of the protrusion, and a moving wheel mounted on the bottom of the support leg. A lead screw is coaxially connected to the output shaft of the rotary motor, and the lead screw is threadedly connected to the support leg. The rotation of the lead screw is converted into vertical linear motion of the support leg by the thread. Limiting components are also provided on the left and right sides of the top rear end of the vehicle frame to restrict the movement of the tank body.

[0008] Preferably, a sliding cavity is vertically formed inside the protrusion, the bottom end of the sliding cavity is open, and the support leg extends into the sliding cavity and can move along the sliding cavity;

[0009] In this design, the sliding cavity provides guiding space for the up-and-down movement of the outriggers, and the open bottom end facilitates the extension and retraction of the outriggers, ensuring stable movement of the outriggers.

[0010] Preferably, a vertical limiting groove is formed on the outer surface of the protrusion, the limiting groove is connected to the interior of the protrusion, and a protruding post is fixed on the outer end face of the support leg, the protruding post extends into the limiting groove, and the limiting groove is used to limit the range of motion of the support leg in the protrusion.

[0011] In this configuration, the limiting groove and the protruding post work together to prevent the outrigger from rotating, ensuring that the outrigger moves accurately in the vertical direction.

[0012] Preferably, front baffles are fixed at the front edges of both the left and right end faces of the tank body. When the tank body is pulled out of the frame backward, the limiting component can block the backward movement of the front baffles.

[0013] In this configuration, the front baffle works in conjunction with the limiting component to restrict the rearward movement of the tank, preventing excessive extraction and detachment.

[0014] Preferably, a rear stop bar is fixed at the rear edge of both the left and right end faces of the tank body. When the tank body is moved forward on the frame to the foremost front of the frame, the limiting component can block the rear side of the rear stop bar.

[0015] In this configuration, the rear stop bar works in conjunction with the limit component to prevent the tank from moving forward and to ensure a stable installation position.

[0016] Preferably, the frame has a plurality of wheel grooves arranged in a rectangular array at positions corresponding to the bottom of the tank, and rollers are rotatably connected in the wheel grooves. The outer circumferential surface of the rollers abuts against the bottom end of the tank, and the rotation direction of the rollers is the same as the movement direction of the tank on the frame.

[0017] In this setting, the rollers reduce friction between the tank and the frame, making the pulling process smoother and reducing the intensity of operation.

[0018] Preferably, the limiting component includes a stand that is vertically fixed on the frame, a stop block that is sleeved on the inner side of the stand and can move laterally, and a threaded rod that is threadedly connected to the stop block. The rotation of the threaded rod is converted into the lateral movement of the stop block under the action of the thread.

[0019] In this setting, the threaded drive between the threaded rod and the stop block allows for precise adjustment of the stop block position, thereby limiting the movement of the tank.

[0020] Preferably, the support has a cavity on its end face near the tank body, the stop block is fitted inside the cavity, the stop block has a threaded hole, the threaded rod is threadedly connected to the threaded hole, the end of the threaded rod has a handwheel, and a connecting shaft is fixedly connected between the handwheel and the threaded rod. The connecting shaft passes through the support and is rotatably connected to the support.

[0021] In this setting, the cavity guide stop block moves, and the handwheel facilitates manual adjustment of the threaded rod, making operation convenient and stable.

[0022] Compared with the prior art, the beneficial effects of this utility model are:

[0023] The water tank structure for fire trucks features a movable component installed in the protrusions on the left and right sides of the tank. By using a rotating motor to drive the lead screw, the outriggers can move vertically and linearly. With the help of the movable wheels at the bottom of the outriggers, the tank can be moved and unloaded independently from the vehicle frame without the need for additional tools. This improves the convenience and timeliness of loading and unloading the water tank, meeting the needs of emergency situations. Attached Figure Description

[0034] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model. Example

[0035] Please see Figures 1-4 A water tank structure for a fire truck includes a tank body 100 mounted on a frame 200. A pair of symmetrically distributed protrusions 110 are provided on both the left and right end faces of the tank body 100. Each protrusion 110 contains a moving assembly 300 for individually moving the tank body 100. The moving assembly 300 includes a support leg 310 fitted inside the protrusion 110 and capable of moving up and down along the protrusion 110, a rotary motor 320 mounted on the top of the protrusion 110, and components mounted on the support leg 310. The bottom of the support leg 310 has a base 311 at the bottom of the movable wheel 330. The movable wheel 330 is installed on the outer side of the base 311. By setting the movable component 300, the rotating motor 320 can drive the lead screw 321 to rotate. Utilizing the principle of thread transmission, the support leg 310 can move up and down along the boss 110, thereby driving the movable wheel 330 to rise and fall. When it is necessary to disassemble the tank 100, the tank 100 can have independent movement capability and can be disassembled from the frame 200 without the aid of other complicated tools, making the operation more convenient.

[0036] like Figure 3 and Figure 4As shown, in this embodiment, a sliding cavity is vertically formed inside the protrusion 110. The bottom end of the sliding cavity is open, and the support leg 310 extends into the sliding cavity and can move along the sliding cavity. The sliding cavity provides a guiding space for the up and down movement of the support leg 310. Its open bottom end design ensures that the support leg 310 can extend and retract smoothly, effectively reducing the possibility of the support leg 310 deviating during movement, thereby ensuring the stability of the movement of the support leg 310. A vertical limiting groove 111 is formed on the outer surface of the boss 110, and the limiting groove 111 is connected to the interior of the boss 110. A protruding post 312 is fixed on the outer end face of the support leg 310, and the protruding post 312 extends into the limiting groove 111. The limiting groove 111 is used to limit the range of motion of the support leg 310 in the boss 110. The limiting groove 111 and the protruding post 312 cooperate with each other to form a reliable limiting structure, ensuring that the support leg 310 can move accurately in the vertical direction, and providing a guarantee for the accurate contact of the moving wheel 330 with the ground. The cross-section of the support leg 310 is rectangular, which can effectively prevent the support leg 310 from rotating during movement.

[0037] like Figure 4 As shown, specifically, a lead screw 321 is coaxially connected to the end of the output shaft of the rotary motor 320. The lead screw 321 is threadedly connected to the support leg 310. The rotary motor 320 serves as a power source, driving the lead screw 321 to rotate through the output shaft. The threaded transmission between the lead screw 321 and the support leg 310 can convert the rotational motion of the lead screw 321 into the vertical linear motion of the support leg 310, thereby controlling the lifting height of the support leg 310 and enabling the moving wheel 330 to smoothly contact or detach from the ground.

[0038] like Figure 2 As shown, furthermore, the frame 200 has several wheel grooves arranged in a rectangular array at positions corresponding to the bottom surface of the tank 100. Rollers 210 are rotatably connected within these grooves. The outer circumferential surface of the rollers 210 abuts against the bottom end of the tank 100. The rotation direction of the rollers 210 is the same as the movement direction of the tank 100 on the frame 200. The rollers 210 on the frame 200 reduce the friction when the tank 100 moves on the frame 200. When the tank 100 is pulled out on the frame 200, the rollers 210 rotate with the movement of the tank 100, making the movement of the tank 100 smoother, reducing the labor intensity of the operator, and also reducing wear between the tank 100 and the frame 200.

[0039] In this embodiment, the water tank structure for a fire truck is used as follows: First, the tank 100 is pulled out to the rear. When the two moving components 300 located at the rear are suspended in the air, the rotation motors 320 of these two moving components 300 are activated. At this time, the output shaft of the rotation motor 320 drives the lead screw 321 to start rotating. The threaded transmission between the lead screw 321 and the support leg 310 causes the support leg 310 to move downward along the sliding cavity in the boss 110, thereby driving the moving wheel 330 downward until it touches the ground, providing stable support for the rear of the tank 100 and preventing the rear of the tank 100 from tilting or falling due to suspension. Then, the tank 100 is pulled out to the rear again. As the tank 100 moves, the two moving components 300 located at the front gradually suspend... At this point, the front end of the tank 100 is still resting on the rear edge of the frame 200. Next, the two front moving components 300 are activated, which, through the rotation of the motor 320, drive the lead screw 321 to rotate, causing the front support leg 310 to move the moving wheel 330 downwards. Finally, when all the moving wheels 330 of the four moving components 300 touch the ground, the tank 100 is completely detached from the support of the frame 200 and can move independently using its own moving wheels 330, successfully completing the disassembly process from the frame 200. The installation process is similar to the disassembly, with the cooperation of the moving components 300 allowing the tank 100 to be smoothly installed onto the frame 200. Example

[0040] To limit the position of the tank 100 on the frame 200 and prevent the tank 100 from detaching from the frame 200 when it is installed on the frame 200 or when it is pulled out of the frame 200 for independent movement, such as... Figures 1-3 and Figure 5 As shown, limit components 400 are also provided on the left and right sides of the top rear end of the frame 200. These limit components 400 are used to restrict the movement of the tank 100. The design of the limit components 400 effectively restricts the movement of the tank 100 at different stages of installation and disassembly, ensuring the stability of the tank 100 on the frame 200 and preventing accidental detachment, thus improving safety during equipment use. The limit components 400 include a stand 410 vertically fixed to the frame 200, a stop block 420 sleeved inside the stand 410 and capable of lateral movement, and a threaded rod 430 threadedly connected to the stop block 420. The rotation of the threaded rod 430 is converted into lateral movement of the stop block 420 by the threaded action. By rotating the threaded rod 430, the lateral position of the stop block 420 inside the stand 410 can be adjusted using the threaded transmission between it and the stop block 420, allowing for accurate limiting of the tank 100 according to actual needs. The operation is simple.

[0041] like Figure 5As shown, specifically, a cavity 411 is formed on the end face of the support 410 near the tank body 100. A stop block 420 is fitted inside the cavity 411. A threaded hole 421 is formed on the stop block 420. A threaded rod 430 is threadedly connected to the threaded hole 421. A handwheel 431 is provided at the end of the threaded rod 430. A connecting shaft is fixedly connected between the handwheel 431 and the threaded rod 430. The connecting shaft passes through the support 410 and is rotatably connected to the support 410. The cavity 411 guides and supports the stop block 420 inside the support 410, ensuring that the stop block 420 remains stable during lateral movement and does not shift or shake. The handwheel 431 provides a convenient operating method for operators. By manually rotating the handwheel 431, the threaded rod 430 can be easily rotated, thereby achieving rapid adjustment of the position of the stop block 420.

[0042] like Figure 3 As shown, furthermore, front baffles 120 are fixed at the front edges of both the left and right end faces of the tank 100. When the tank 100 is pulled out of the frame 200, the limiting component 400 can block the rearward movement of the front baffles 120. The front baffles 120 and the stop blocks 420 in the limiting component 400 cooperate with each other. During the process of pulling out the tank 100, when the tank 100 moves to a certain position, the stop blocks 420 can contact the front baffles 120 and block it from continuing to move backward, effectively limiting the distance the tank 100 moves backward, preventing the tank 100 from falling off the frame 200 due to excessive movement, and ensuring the safety of the tank 100 during disassembly. Rear stop bars 130 are fixed at the rear edges of both the left and right end faces of the tank body 100. When the tank body 100 is moved forward on the frame 200 to the front end of the frame 200, the limiting component 400 can block the rear side of the rear stop bar 130. The cooperation between the rear stop bar 130 and the limiting component 400 plays an important role in the installation of the tank body 100. When the tank body 100 moves forward to the front end of the frame 200, the stop block 420 blocks the rear side of the rear stop bar 130, which can prevent the tank body 100 from shifting backward and falling off the frame 200 after installation.

[0043] It is worth noting that the rotary motor 320 involved in this utility model is existing conventional technology, and will not be described in detail here.

[0044] In this embodiment, when using the water tank structure for a fire truck, the tank body 100 is moved forward along the rollers 210 on the frame 200 to the foremost position of the frame 200 during installation. At this time, the operator manually rotates the handwheel 431. The handwheel 431 drives the threaded rod 430 to rotate via the connecting shaft. The threaded transmission between the threaded rod 430 and the stop block 420 causes the stop block 420 to move closer to the tank body 100. Finally, the stop block 420 blocks the rear side of the rear stop bar 130, forming a reliable limiting structure and effectively preventing the tank body 100 from moving forward. The tank 100 detaches from the frame 200, ensuring a stable installation of the tank 100 on the frame 200. When pulling the tank 100 out of the frame 200, pull it out backward until the two moving components 300 on the front side are activated. Then, the operator rotates the handwheel 431 to move the stop block 420 closer to the tank 100. This stops the stop block 420 behind the front stop bar 120, preventing the tank 100 from falling directly from the frame 200 due to inertia or other external forces, ensuring safety during the extraction process. Once the front moving component 300 is activated and the moving wheel 330 touches the ground, the tank 100 has stable support. At this point, the handwheel 431 is adjusted to move the stop block 420 away from the tank 100, allowing the tank 100 to continue to be extracted smoothly.

Those skilled in the art should understand that this utility model is not limited to the above embodiments.
