[0040] The specific implementation of the present application is described in detail below in conjunction with the accompanying drawings. It should be understood that the specific implementation described here is only used to illustrate and explain the present application, and is not used to limit the present application.

[0041] The trolley-type compressed air foam device produces a large amount of compressed air foam by mixing compressed air with foam fire extinguishing agent. The compressed air foam can adhere to the combustibles, isolating the combustibles from the air, while reducing the temperature and destroying the combustion conditions, thereby achieving the purpose of extinguishing the fire. Among them, the compressed air is stored in a gas cylinder, and the foam fire extinguishing agent is stored in a liquid storage tank. The liquid storage tank can be equipped with gas pipe joints, water pipe joints, mixers, valve bodies, pressure indicators and other components.

[0042] When the compressed air foam device is being transported or at the rescue site, the device may fall over or collide. The parts installed on the liquid storage tank have high requirements for sealing and precision. If the parts collide with other objects, the sealing and precision will be affected, causing damage to the compressed air foam device and even affecting its normal use.

[0043] In view of this, if Figure 1 , Figure 2 as well as Figure 3 As shown, the present application provides a trolley frame for a fire extinguishing device, which includes a frame, a wheel set 7 and a handle assembly 1. The wheel set 7 is rotatably arranged at the lower part of the frame, and the handle assembly 1 is arranged on the frame. The frame has a peripheral wall and a top wall. The peripheral wall surrounds a liquid storage tank accommodating cavity for installing a liquid storage tank 11. The top wall is located above the peripheral wall and can open or close the upper opening of the liquid storage tank accommodating cavity. In this way, the peripheral wall and the top wall of the frame can serve as a protective shell for the liquid storage tank and the components installed on the liquid storage tank. When the fire extinguishing device is overturned or collides, the peripheral wall and the top wall of the frame can protect the liquid storage tank and the components installed on the liquid storage tank to prevent the liquid storage tank and the components installed on the liquid storage tank from directly colliding with the object to be collided, thereby making the structure of the fire extinguishing device more reliable and having better safety performance.

[0044] The peripheral wall and the top wall of the frame can have various structural forms, for example, the peripheral wall is cylindrical, prismatic or square, and the top wall is flat or bottle cap. The peripheral wall can be an integrally formed cylinder or a spliced ​​cylinder. The wheel set 7 can be a 2-wheel, 3-wheel or 4-wheel structure. The handle assembly 1 can be integrally formed with the frame or can be an independent component mounted on the frame. The shape of the handle assembly 1 can also be various. The fire extinguishing device can be a compressed air foam fire extinguishing device or other foam fire extinguishing devices.

[0045] In some specific embodiments, the vehicle frame may include an upper housing assembly 8, a front housing assembly 9, and a rear housing assembly 10, wherein the front housing assembly 9 and the rear housing assembly 10 are connected in the front-to-back direction, the peripheral wall of the vehicle frame is formed on the front housing assembly 9 and the rear housing assembly 10, the upper housing assembly 8 is arranged above the front housing assembly (9) and the rear housing assembly 10, and the top wall of the vehicle frame is formed on the upper housing assembly 8. The front housing assembly 9 and the rear housing assembly 10 are detachably connected to facilitate the installation and removal of the liquid storage tank 11. For example, the front housing assembly 9 and the rear housing assembly 10 may be connected by bolt fasteners or snap-on connection, etc.

[0046] Alternatively, if Figure 1 , Figure 2 as well as Figure 3As shown, a water pipe rack assembly 2 is provided on the outer side of the frame, and the water pipe rack assembly 2 includes a first bracket 21 and a second bracket 22 which are arranged at intervals and extend outward respectively, so that the water pipe can be wound around the first bracket 21 and the second bracket 22, which is convenient for storing longer water pipes.

[0047] When the fire extinguishing device is a compressed air foam fire extinguishing device, since the gas cylinder storing the compressed air is a high-pressure gas cylinder, there is a risk of explosion when the fire extinguishing device is tipped over. The existing cart-type compressed air foam device has a relatively simple structure and cannot effectively resist accidents such as collision and tipping.

[0048] In order to avoid the possibility of collision and explosion of the high-pressure gas cylinder due to the overturning or collision of the entire fire extinguishing device, and to facilitate the fixation during transportation, the first bracket 21 and the second bracket 22 of the present application define an installation area for installing the gas cylinder 4, and the water pipe rack assembly 2 extends outward from the gas cylinder 4 so that the gas cylinder 4 can be suspended when the fire extinguishing device falls backward or collides. In this way, when the compressed air foam fire extinguishing device falls or collides, the water pipe rack assembly can first be erected on the object to be collided and the gas cylinder can be suspended on the object to be collided. In this way, the gas cylinder and the object to be collided will not collide directly, so that the gas cylinder can be protected, reducing the risk of explosion due to collision of the gas cylinder, making the structure of the fire extinguishing device more reasonable and reliable, with high safety performance, and also convenient for fixation during transportation.

[0049] Among them, the water pipe rack assembly 2 can be in the form of a rod-shaped bracket, a plate-shaped bracket, or a box-shaped bracket; alternatively, the water pipe rack assembly 2 can be integrally formed with the vehicle frame, or can be an independent component installed on the vehicle frame; alternatively, the water pipe rack assembly 2 includes a plurality of vertical sub-brackets arranged at intervals in the horizontal direction, or can be a plurality of horizontal sub-brackets arranged at intervals in the vertical direction, etc., but the present application is not limited to this.

[0050] It should be noted that in the present application, unless otherwise specified, directional words such as "up and down" generally refer to two opposite directions along a vertical line; "left and right" generally refer to two opposite directions along a horizontal line; "inside" refers to a position relatively close to the center point of the compressed air foam fire extinguishing device, and "outside" refers to a position relatively far from the center point of the compressed air foam fire extinguishing device.

[0051] In some specific embodiments, the first bracket 21 and the second bracket 22 are arranged at intervals in the upper and lower parts, and the first bracket 21 and the second bracket 22 are respectively arranged on the rear side of the frame and extend in the horizontal direction. The outer ends of the first bracket 21 and the second bracket 22 respectively extend backwards to the outside of the gas cylinder 4 and the extension lengths are equal. In this way, the first bracket 21 and the second bracket 22 form two fulcrums that can suspend the gas cylinder 4 on the object to be collided, and can stably and reliably support the gas cylinder 4.

[0052] In some specific embodiments, a mounting area for mounting the gas cylinder 4 is defined between the lower portion of the first bracket 21 and the upper portion of the second bracket 22. The trolley frame further includes a restraining member 3 disposed between the first bracket 21 and the second bracket 22 and used to fix the gas cylinder 4. The restraining member 3 may be a strap or a buckle. Figure 1 , Figure 2 as well as Figure 3 As shown, the binding member 3 includes an upper binding member 31 and a lower binding member 32 which are spaced apart from each other to securely bind the gas cylinder 4. When the gas cylinder needs to be replaced, the binding belt and the connection between the gas cylinder and the air inlet pipe can be untied.

[0053] Optionally, the outer end of the first bracket 21 is formed with an upper bending limit portion that bends upward, and the outer end of the second bracket 22 is formed with a lower bending limit portion that bends downward, so that the water pipe rack assembly 2 can also have the function of fixing the water pipe. Figure 1 , Figure 2 as well as Figure 3 As shown, the first bracket 21 has a water pipe hanging platform portion 25 extending in the horizontal direction, the water pipe hanging platform portion 25 is used to hang the water pipe, the rear end of the water pipe hanging platform portion 25 is bent upward to form an upper bending limit portion, and the second bracket 22 is formed with a lower support platform portion 26 extending in the horizontal direction and used to support the gas cylinder, and the lower support platform portion 26 is bent downward to form a lower bending limit portion. In a non-use state, the water pipe can be arranged between the first bracket 21 and the second bracket 22, and the upper bending limit portion and the lower bending limit portion can prevent the water pipe from falling out.

[0054] In some specific embodiments, the handle assembly 1 and the water pipe rack assembly 2 are respectively extended backward from the rear end of the peripheral wall of the frame, and the backward extension lengths of the handle assembly 1 and the water pipe rack assembly 2 are equal, or the backward extension length of the handle assembly 1 is greater than the backward extension length of the water pipe rack assembly 2. In this way, the handle assembly 1 can work together with the water pipe rack assembly 2 to suspend the gas cylinder 4 when the compressed air foam fire extinguishing device falls backward or collides.

[0055] Furthermore, due to the heavy weight of the liquid storage tank, the bottom of the liquid storage tank accommodating cavity is open to have a bottom opening, which facilitates the installation and removal of the liquid storage tank 11.

[0056] Among them, the upper shell assembly 8, the front shell assembly 9 and the rear shell assembly 10 can be set as a sheet metal structure and connected by bolts to form a direct shell of the fire extinguishing device. A plurality of steel sheets can be welded on the liquid storage tank 11, and the liquid storage tank 11 is connected to the shell through a plurality of steel sheets and a plurality of stud bolts. Moreover, under the premise of ensuring the overall strength of the shell, part of the steel plate can be cut off from the upper shell assembly 8, the front shell assembly 9 and the rear shell assembly 10, so that materials can be saved and the overall weight of the vehicle body can be reduced.

[0057] Optionally, the trolley frame may also be provided with a water cannon mount for fixing the water cannon. To further save materials and reduce the weight of the vehicle body, the water cannon mount may be formed as a tongue 6 turned outward on the upper housing assembly 8, the front housing assembly 9 or the rear housing assembly 10. Figure 1 , Figure 2 as well as Figure 3 As shown, a tongue piece 6 turned outward is formed on the sheet metal shell on the left or right side of the frame, and the tongue piece 6 is provided with an insertion hole for inserting a water cannon.

[0058] In some specific embodiments, Figure 1 , Figure 2 as well as Figure 3 As shown, the handle assembly 1, the water pipe rack assembly 2, the restraint 3 and the wheel assembly 7 are arranged from top to bottom on the rear end of the rear housing assembly 10. The rear housing assembly 10 is also provided with a water outlet pipe hole 101 and an air inlet pipe hole 102 communicating with the liquid storage tank accommodating cavity, the gas cylinder 4 is provided with an air outlet pipe, the air outlet pipe extends from the air inlet pipe hole 102 into the liquid storage tank accommodating cavity, and the water outlet pipe 12 of the liquid storage tank 11 extends from the water outlet pipe hole 101 to the outside of the liquid storage tank accommodating cavity.

[0059] On the other hand, the present application also provides a fire extinguishing device, which includes the above-mentioned cart frame, liquid storage tank 11 and gas cylinder 4, wherein the liquid storage tank 11 and gas cylinder 4 are respectively arranged on the cart frame. The fire extinguishing device has all the technical effects brought by the cart frame, so it will not be repeated.

[0060] Since the existing cart-type compressed air foam device has three wheels or more, the fire extinguishing device may slide when in use, affecting rescue operations. Figure 1 , Figure 2 as well as Figure 3 As shown, the wheel set 7 is a two-wheel structure. When the fire extinguishing device is placed vertically, the bottom end of the liquid storage tank 11 and the bottom end of the wheel set 7 are located on the same horizontal plane. In this way, the fire extinguishing device can stand still on the ground when in use, so that the entire fire extinguishing device remains stable. When the fire extinguishing device needs to be moved, the handle assembly 1 is pressed down and pressed against the wheel set 7 at the same time to achieve the pushing of the fire extinguishing device.

[0061] Optionally, the fire extinguishing device further includes a water monitor 5 and a water outlet pipe 12 connected between the water monitor 5 and the liquid storage tank 11 , and the water outlet pipe 12 is wound around the water pipe rack assembly 2 .

[0062] In summary, the fire extinguishing device and its trolley frame of the present application can realize the functions of fixing, protecting, moving and rapid replacement of gas cylinders, effectively resist the safety hazards caused by collision and overturning, are more convenient for transportation, and have better stability when in use.
