Description

Technical Field

[0001] The present invention belongs to the technical field of fire-fighting equipment, and particularly relates to a fire hose handling device. Background Art

[0002] A fire hose is a flexible hose used to transport high-pressure water or flame-retardant liquids such as foam. Traditional fire hoses have a rubber lining and are wrapped with linen fabric on the outer surface. Advanced fire hoses are made of composite materials such as polyurethane. Both ends of the fire hose have metal connectors, which can be connected to another hose to extend the distance or to a nozzle to increase the liquid spraying pressure. The usage steps of a fire hose generally include the following aspects: Inspect the hose: Before use, check whether the hose has any damage, cracks or other defects; Connect to the water source: Connect one end of the hose to the fire water source; Unroll the hose: Unroll the hose from the reel, ensuring that there are no kinks or entanglements; Connect the nozzle: Connect the nozzle to the other end of the hose; Open the water source: Open the water source and check whether there is any leakage at the connection between the hose and the nozzle; Adjust the nozzle: Adjust the spraying mode of the nozzle as needed and prepare for fire extinguishing; Fire extinguishing operation: Conduct fire extinguishing according to the situation, keeping the hose stable and safe; Reel up after use: After fire extinguishing, close the water source and reel up the hose according to the double-layer reeling method to avoid twisting and damage.

[0003] During long-distance fire extinguishing, the hoses are also spliced. At present, most firefighters carry fire hoses manually. Since this method can carry a small number of fire hoses, it wastes a lot of manpower for handling. At the same time, the subsequent reeling process is often also carried out manually, which is rather troublesome. Summary of the Invention

[0004] The technical problem to be solved by the present invention is to overcome the above-mentioned disadvantages of the prior art and provide a fire hose handling device.

[0005] The technical solution adopted to solve the above technical problem is: to provide a fire hose handling device, which includes an external support frame and an internal support frame, and a limiting support mechanism is arranged between both sides of the external support frame and the internal support frame;

[0006] A rotating support mechanism is rotatably connected between both sides of the external support frame and the internal support frame. On one side away from the external support frame and the internal support frame, the two rotating support mechanisms are respectively fixedly connected with a sealing cover plate and an adjusting and sealing mechanism;

[0007] A reel rod mechanism is slidably connected between the two rotating support mechanisms. A winding isolation mechanism is rotatably connected to the top of the external support frame. Moving mechanisms are arranged on both sides of the bottom of the external support frame and the internal support frame. A winding hose is wound between the center of the outer wall of the reel rod mechanism and the winding isolation mechanism.

[0008] Furthermore, both the external support frame and the internal support frame are welded by circular tubes and rings.

[0009] Through the above technical solution, it is ensured that the external support frame and the internal support frame can be rotated and opened and closed through the ring, and the support is realized through the circular tube structure.

[0010] Furthermore, the limit support mechanism respectively includes a fixed shaft seat fixedly connected to the outer wall of the external support frame and a limit clamping rod fixedly connected to the internal support frame, and a support clamping plate is rotatably connected to the fixed shaft seat.

[0011] Through the above technical solution, the external support frame and the internal support frame can be supported and fixed by rotating the support clamping plate to clamp on the limit clamping rod.

[0012] Furthermore, the horizontal height of the fixed shaft seat is greater than that of the limit clamping rod.

[0013] Through the above technical solution, it is ensured that after the external support frame and the internal support frame are combined, there will be no conflict in the positions of the fixed shaft seat and the limit clamping rod, and it is ensured as much as possible that the external support frame and the internal support frame can fit each other, which is convenient for the firefighter to hold with one hand.

[0014] Furthermore, the rotation support mechanism includes a support shaft sleeve arranged on the outer wall of the ring on one side of the external support frame and the internal support frame. One side of the support shaft sleeve is fixedly connected with an arc-shaped limit sleeve plate, the outer wall of the arc-shaped limit sleeve plate is fixedly connected with a side water hose baffle, a connecting bearing is arranged on the inner wall of the support shaft sleeve, and a guiding hopper is installed between one side of the connecting bearing and the inner wall of the support shaft sleeve.

[0015] Through the above technical solution, when the external support frame and the internal support frame are opened, the rotation support of the external support frame and the internal support frame is realized through the support shaft sleeve, the maximum opening and closing angle is limited through the arc-shaped limit sleeve plate, the rotation support of the overall winding shaft rod mechanism is realized through the connecting bearing, and at the same time, when the winding shaft rod mechanism is inserted, the quick insertion can be realized through the guiding structure of the guiding hopper.

[0016] Furthermore, the adjustment and sealing mechanism includes a sealing ring installed on one side of the rotation support mechanism. A plurality of fixing bolts are installed between the sealing ring and the rotation support mechanism. Fixed rotating shafts are fixedly connected to the top and bottom of the other side of the sealing ring. A sealing sleeve is rotatably connected to the fixed rotating shaft at the bottom of the sealing ring. A connecting pull plate is slidably connected to the inner wall of the sealing sleeve, and two first return springs are fixedly connected between the bottom of the connecting pull plate and the inner wall of the sealing sleeve.

[0017] Through the above technical solution, when it is necessary to extract the take-up reel rod mechanism or rotate the take-up reel rod mechanism, pull up the connecting pull plate to stretch the first return spring and then rotate it, so that the connecting pull plate disengages from the fixed rotating shaft at the top. During subsequent sealing, pull the connecting pull plate to rotate, and drive the sealing sleeve to rotate at the same time. Then pull the connecting pull plate to stretch the first return spring to clamp the other end of the connecting pull plate on the fixed rotating shaft at the top. The continuous pulling force of the first return spring on the connecting pull plate ensures that the sealing sleeve can cooperate well with the sealing cover plate to seal the take-up reel rod mechanism, so that it will not shift during rotation.

[0018] Further, the top of the connecting pull plate is a hook structure.

[0019] Through the above technical solution, it is ensured that the hook structure at the top of the connecting pull plate can realize clamping and fixing with the fixed rotating shaft.

[0020] Further, the take-up reel rod mechanism includes a take-up reel rod sleeve slidably connected between two rotating support mechanisms. An internal extension rod is slidably connected to the inner wall of the take-up reel rod sleeve at one end close to the adjusting and sealing mechanism. The other end of the internal extension rod is fixedly connected with a limiting circular plate. One end of the inner wall of the internal extension rod is rotatably connected with a first rotating rod, and one end of the inner wall of the first rotating rod is rotatably connected with a second rotating rod.

[0021] Through the above technical solution, during subsequent winding, after rotating and opening the sealing sleeve, pull the limiting circular plate to pull out the internal extension rod, rotate the first rotating rod and the second rotating rod respectively to open the right-angled structure. After folding the middle section of the fire hose in double layers, pass it through the corresponding rolling sleeve, and then wind the other end around the outer wall of the take-up reel rod sleeve. At this time, rotate the second rotating rod to drive the take-up reel rod sleeve to start winding the hose.

[0022] Further, the winding and isolating mechanism includes two side connecting rods and a plurality of connecting partitions rotatably connected to the top of the external support frame. A connecting shaft rod is fixedly connected between the two side connecting rods and the plurality of connecting partitions. The other ends of the plurality of connecting partitions are fixedly connected with a central hose partition, and a plurality of rolling sleeves are rotatably connected to the outer wall of the connecting shaft rod.

[0023] Through the above technical solution, the isolation of a plurality of fire hoses can be well realized through a plurality of connecting partitions and two side hose baffles. At the same time, during the winding process, the water in the hose can be well squeezed out through the rolling sleeve, avoiding the water remaining in the wound hose.

[0024] Furthermore, the moving mechanism includes two grooved collars fixedly connected to the bottom of the external support frame or the internal support frame. On both sides of the outer walls of the two grooved collars, rotating bases are rotatably connected. At the bottom of each of the two rotating bases, a universal wheel is installed. At the top of each of the two rotating bases, a sliding limit shell is fixedly connected. Inside the inner walls of the two sliding limit shells, square blocks are slidably connected. Between the two sides of the top of each of the two square blocks and the inner surface of the top of the corresponding sliding limit shell, a second return spring is fixedly connected. Between the tops of the two square blocks, a two-end connecting rod is fixedly connected.

[0025] Through the above technical solution, during normal use, the overall device can be moved through the moving mechanism. At the same time, to ensure the stability of winding, the two-end connecting rod can be pulled to drive the two square blocks to move, so that the two square blocks are disengaged from the clamping of the two grooved collars, and then rotated to make the two rotating bases rotate by a certain angle, so that the planes of the two rotating bases contact the ground. At this time, the overall device is not convenient to move, which is convenient for winding and rotating work. At the same time, at this moment, the bottom of the square block fits against the outer wall of the grooved collar and continuously generates pressure. After the rollers need to be used later, the two rotating bases can be rotated to reset them. Under the elastic force of multiple second return springs, the two square blocks can be clamped in the corresponding grooved collars to achieve re-fixation.

[0026] The beneficial effects of the present invention are as follows: (1) By designing the winding shaft rod mechanism and the winding isolation mechanism, the present invention enables the device to carry multiple fire hoses. And by designing the adjustment and sealing mechanism, the winding shaft rod mechanism can be completely drawn out to quickly disassemble multiple fire hoses. At the same time, during the subsequent winding process, the winding can be quickly achieved through the winding shaft rod mechanism. In cooperation with the rolling sleeve, the water in the fire hose can be well squeezed out through the rolling sleeve, avoiding the water remaining in the wound fire hose. At the same time, with the combination of the external support frame and the internal support frame, the overall device can be pulled through the moving mechanism to achieve movement, improving the efficiency of transporting fire hoses; (2) By designing the moving mechanism, during normal use, the overall device can be moved through the moving mechanism. At the same time, to ensure the stability of winding, the universal wheels can be rotated through the rotating bases so that the planes of the rotating bases contact the ground to ensure that the winding can rotate stably. When the device needs to be moved later, the two square blocks can be clamped in the corresponding grooved collars to achieve re-fixation, which is very convenient and fast.

Detailed implementation manners

[0043] In order to make the objectives, technical solutions and advantages of the present invention clearer and more understandable, the present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0044] As Figures 1-4 shown, a fire hose handling device of this embodiment includes an external support frame 1 and an internal support frame 2. Both the external support frame 1 and the internal support frame 2 are welded by round tubes and rings, ensuring that the external support frame 1 and the internal support frame 2 can be rotated and opened and closed through the rings, and the support is realized through the round tube structure. Limit support mechanisms 3 are arranged between both sides of the external support frame 1 and the internal support frame 2. The limit support mechanisms 3 respectively include a fixed shaft seat 301 fixedly connected to the outer wall of the external support frame 1 and a limit clamping rod 302 fixedly connected to the internal support frame 2. A support clamping plate 303 is rotatably connected to the fixed shaft seat 301. The support clamping plate 303 rotates and clamps on the limit clamping rod 302 to realize the support and fixation of the external support frame 1 and the internal support frame 2. The horizontal height of the fixed shaft seat 301 is greater than that of the limit clamping rod 302, ensuring that after the external support frame 1 and the internal support frame 2 are combined, the positions of the fixed shaft seat 301 and the limit clamping rod 302 will not conflict, and as much as possible ensuring that the external support frame 1 and the internal support frame 2 can fit together, facilitating a firefighter to hold with one hand.

[0045] As Figures 1-8As shown in the figure, a rotating support mechanism 4 is rotatably connected between the two sides of the outer support frame 1 and the inner support frame 2. The rotating support mechanism 4 includes a support shaft sleeve 401 provided on the outer wall of the circular ring on one side of the outer support frame 1 and the inner support frame 2. One side of the support shaft sleeve 401 is fixedly connected with an arc-shaped limiting sleeve plate 402. The outer wall of the arc-shaped limiting sleeve plate 402 is fixedly connected with a side water belt baffle 403. A connecting bearing 404 is arranged on the inner wall of the support shaft sleeve 401. A guiding hopper 405 is installed between one side of the connecting bearing 404 and the inner wall of the support shaft sleeve 401. When the outer support frame 1 and the inner support frame 2 are opened, the rotation support of the outer support frame 1 and the inner support frame 2 is realized through the support shaft sleeve 401. The maximum opening and closing angle is limited by the arc-shaped limiting sleeve plate 402. The rotation support of the overall winding shaft mechanism 7 is realized through the connecting bearing 404. At the same time, when the winding shaft mechanism 7 is inserted, the rapid insertion can be realized through the guiding structure of the guiding hopper 405.

[0046] As Figures 1-8 shown, on the side far from the outer support frame 1 and the inner support frame 2, the two rotating support mechanisms 4 are respectively fixedly connected with a sealing cover plate 5 and an adjusting sealing mechanism 6. The adjusting sealing mechanism 6 includes a sealing ring 601 installed on one side of the rotating support mechanism 4. A plurality of fixing bolts 602 are installed between the sealing ring 601 and the rotating support mechanism 4. The top and bottom of the other side of the sealing ring 601 are both fixedly connected with fixing rotating shafts 603. A sealing sleeve 604 is rotatably connected to the fixing rotating shaft 603 at the bottom of the sealing ring 601. A connecting pull plate 605 is slidably connected to the inner wall of the sealing sleeve 604. Two first return springs 606 are fixedly connected between the bottom of the connecting pull plate 605 and the inner wall of the sealing sleeve 604. When it is necessary to extract the winding shaft mechanism 7 or rotate the winding shaft mechanism 7, pull up the connecting pull plate 605 and stretch the first return spring 606 and then rotate it to make the connecting pull plate 605 disengage from the fixing rotating shaft 603 at the top. During subsequent sealing, pull the connecting pull plate 605 to rotate and drive the sealing sleeve 604 to rotate simultaneously. Then pull the connecting pull plate 605 to stretch the first return spring 606 to clamp the other end of the connecting pull plate 605 on the fixing rotating shaft 603 at the top. The continuous pulling force of the first return spring 606 on the connecting pull plate 605 ensures that the sealing sleeve 604 can cooperate well with the sealing cover plate 5 to realize the sealing of the winding shaft mechanism 7, so that it will not shift during the rotation process. The top of the connecting pull plate 605 is a hook structure, which ensures that the hook structure at the top of the connecting pull plate 605 can realize the clamping and fixing with the fixing rotating shaft 603.

[0047] As Figures 1-10As shown, a winding shaft rod mechanism 7 is slidably connected between two rotating support mechanisms 4. The winding shaft rod mechanism 7 includes a winding shaft rod sleeve 701 slidably connected between the two rotating support mechanisms 4. An inner built-in extension rod 702 is slidably connected to the inner wall of one end of the winding shaft rod sleeve 701 close to the adjusting and blocking mechanism 6. The other end of the inner built-in extension rod 702 is fixedly connected with a limiting circular plate 703. One end of the inner wall of the inner built-in extension rod 702 is rotatably connected with a first rotating rod 704, and one end of the inner wall of the first rotating rod 704 is rotatably connected with a second rotating rod 705. During the subsequent winding process, after rotating and opening the blocking sleeve 604, pull the limiting circular plate 703 to pull out the inner built-in extension rod 702, and rotate the first rotating rod 704 and the second rotating rod 705 respectively to open them in a right-angle structure. After folding the middle section of the fire hose in double layers, make it pass through the corresponding rolling sleeve 805, and then wind the other end around the outer wall of the winding shaft rod sleeve 701. At this time, rotate the second rotating rod 705, and then start to drive the winding shaft rod sleeve 701 to start winding the hose.

[0048] As Figures 1-15As shown in the figure, a winding isolation mechanism 8 is rotatably connected to the top of the external support frame 1. The winding isolation mechanism 8 includes two side connecting rods 801 rotatably connected to the top of the external support frame 1 and a plurality of connecting partitions 803. A connecting shaft rod 802 is fixedly connected between the two side connecting rods 801 and the plurality of connecting partitions 803. The other ends of the plurality of connecting partitions 803 are all fixedly connected with a central water hose partition 804. A plurality of rolling sleeves 805 are rotatably connected to the outer wall of the connecting shaft rod 802. Through the plurality of connecting partitions 803 and the two side water hose baffles 403, the isolation of a plurality of fire hoses can be well realized. At the same time, during the winding process, the residual water in the water hose can be well squeezed out through the rolling sleeves 805, avoiding the situation in the wound water hose. Moving mechanisms 9 are arranged on both sides of the bottom of the external support frame 1 and the internal support frame 2. The moving mechanism 9 includes two grooved socket sleeves 901 fixedly connected to the bottom of the external support frame 1 or the internal support frame 2. Rotating bases 902 are rotatably connected to both sides of the outer walls of the two grooved socket sleeves 901. Universal wheels 903 are installed at the bottoms of the two rotating bases 902. Sliding limit shells 904 are fixedly connected to the tops of the two rotating bases 902. Square clamping blocks 905 are slidably connected to the inner walls of the two sliding limit shells 904. Second return springs 906 are fixedly connected between the two sides of the tops of the two square clamping blocks 905 and the inner surfaces of the tops of the corresponding sliding limit shells 904. An end connecting rod 907 is fixedly connected between the tops of the two square clamping blocks 905. During normal use, the overall device can be moved through the moving mechanism 9. At the same time, in order to ensure the stability of winding, the end connecting rod 907 can be pulled to drive the two square clamping blocks 905 to move, so that the two square clamping blocks 905 are disengaged from the clamping of the two grooved socket sleeves 901, and then rotated to make the two rotating bases 902 rotate by a certain angle, so that the planes of the two rotating bases 902 contact the ground. At this time, the overall device is not convenient to move, which is convenient for winding rotation work. At the same time, at this moment, the bottom of the square clamping block 905 fits on the outer wall of the grooved socket sleeve 901 and continuously generates pressure. After the rollers need to be used later, the two rotating bases 902 can be rotated to reset them. Under the elastic force of the plurality of second return springs 906, the two square clamping blocks 905 can be clamped in the corresponding grooved socket sleeves 901 to achieve re-fixation. A winding water hose 10 is wound between the center of the outer wall of the winding shaft rod mechanism 7 and the winding isolation mechanism 8.

[0049] The working principle of this embodiment is as follows. When in use, the wound fire hoses can be completely installed on the handling device by opening the adjusting and blocking mechanism 6 and inserting them into the winding shaft rod mechanism 7. At the same time, when inserting the winding shaft rod mechanism 7, the winding isolation mechanism 8 needs to be rotated to a suitable position so that the winding shaft rod mechanism 7 can be inserted into the winding isolation mechanism 8 (fast insertion can be achieved through the guiding structure of the guiding hopper 405). The isolation of a plurality of fire hoses is realized through the winding isolation mechanism 8;

[0050] When storing, the external support frame 1 and the internal support frame 2 are opened (the maximum opening and closing angle is determined by the arc-shaped limit sleeve plate 402), and then the support card plate 303 is rotated to be stuck on the limit card rod 302 to realize the support and fixation of the external support frame 1 and the internal support frame 2. When carrying the water hose subsequently, the support card plate 303 is rotated and then the external support frame 1 and the internal support frame 2 are combined. The top of the combined external support frame 1 and internal support frame 2 is pulled, and the overall device and multiple water hoses can be pulled through the moving mechanism 9 at the bottom of the external support frame 1 or the internal support frame 2. After reaching the designated position, the external support frame 1 and the internal support frame 2 are opened and the support card plate 303 is clamped to complete the fixation. At this time, one end of the winding water hose 10 can be pulled, and then through the rotation of the winding shaft rod mechanism 7, the release of the winding water hose 10 is realized. At the same time, in case of emergency, the connecting pull plate 605 can be pulled upward to stretch the first return spring 606 and then rotated, so that the connecting pull plate 605 is separated from the fixed rotating shaft 603 at the top, and the whole winding shaft rod mechanism 7 is directly pulled out, so that multiple fire hoses are quickly separated from the device and thrown out manually quickly;

[0051] In the subsequent winding process, after the blocking sleeve 604 is rotated and opened, the limit circular plate 703 is pulled to pull out the built-in extension rod 702. The first rotating rod 704 and the second rotating rod 705 are respectively rotated to open in a right-angle structure. After the middle section of the fire hose is selected and folded in double layers, it is passed through the rolling sleeve 805 at the corresponding position, and then the other end is wound around the outer wall of the winding shaft sleeve 701. At this time, the second rotating rod 705 is rotated, and then the winding shaft sleeve 701 is driven to start winding the water hose. The water hose passes through the rolling sleeve 805, and the residual water in the water hose can be well squeezed out to avoid the residual water in the wound water hose. At the same time, in order to ensure the stability of winding, the two end connecting rods 907 can be pulled to drive the two square clamping blocks 905 to move, so that the two square clamping blocks 905 are separated from the clamping of the two groove clamping sleeves 901, and then rotated, so that the two rotating bases 902 are rotated by a certain angle, and the planes of the two rotating bases 902 are in contact with the ground. At this time, the overall device is not convenient to move, which is convenient for winding and rotating work. At the same time, at this moment, the bottom of the square clamping block 905 is attached to the outer wall of the groove clamping sleeve 901 and continuously generates pressure. After the rollers need to be used subsequently, the two rotating bases 902 are rotated to reset them. Under the elastic force of the multiple second return springs 906, the two square clamping blocks 905 can be clamped in the corresponding groove clamping sleeves 901 to realize re-fixation. After winding is completed, the external support frame 1 and the internal support frame 2 are combined and the overall device is pulled to realize handling.

[0052] The above is only a preferred embodiment of the present invention and is not used to limit the protection scope of the present invention.
