Description

Technical Field

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

[0002] A fire hose is a flexible pipe used to transport flame-retardant liquids such as high-pressure water or foam. Traditional fire hoses are lined with rubber and covered with linen braid on the outside. Advanced fire hoses are made of composite materials such as polyurethane. There are metal connectors on both ends of the fire hose, which can be connected to another hose to extend the distance or to a nozzle to increase the liquid spray pressure. The steps for using a fire hose usually include the following aspects: Inspect the hose: Before use, check whether the hose has damage, cracks or other defects; Connect the water source: Connect one end of the hose to the fire water source; Unroll the hose: Unroll the hose from the reel, making sure there are no kinks or entanglements; Connect the nozzle: Connect the nozzle to the other end of the hose; Turn on the water source: Turn on the water source and check whether there are any leaks at the connection between the hose and the nozzle; Adjust the nozzle: Adjust the nozzle's spray pattern as needed and prepare to extinguish the fire; Fire extinguishing operation: Extinguish the fire according to the situation and keep the hose stable and safe; Rewind after use: After extinguishing the fire, turn off the water source and rewind the hose using the double-layer reeling method to avoid twisting and damage.

[0003] When extinguishing a fire over a long distance, the hoses will be spliced. At the same time, the existing firefighters mostly carry the fire hoses manually. Since the number of fire hoses carried in this way is small, a lot of manpower is wasted in carrying them. At the same time, the subsequent reeling process is often also done manually, which is more troublesome. Summary of the Invention

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

[0005] The technical solution adopted to solve the above technical problems is: providing a fire hose carrying device, comprising an external support frame and an internal support frame, wherein a limited support mechanism is provided between both sides of the external support frame and the internal support frame; A rotation support mechanism is rotatably connected between both sides of the external support frame and the internal support frame, and a blocking cover plate and an adjustment blocking mechanism are fixedly connected to the two rotation support mechanisms on one side away from the external support frame and the internal support frame respectively; A winding shaft 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, and moving mechanisms are provided on both sides of the bottom of the external support frame and the internal support frame. A winding water hose is wound between the center of the outer wall of the winding shaft mechanism and the winding isolation mechanism.

[0006] Furthermore, the external support frame and the internal support frame are both formed by welding a circular tube and a circular ring.

[0007] 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 circular ring, and support is achieved through the circular tube structure.

[0008] Furthermore, the position-limiting support mechanism includes a fixed shaft seat fixedly connected to the outer wall of the external support frame and a position-limiting clamping rod fixedly connected to the internal support frame, and a support clamping plate is rotatably connected to the fixed shaft seat.

[0009] 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 be clamped on the limiting clamping rod.

[0010] Furthermore, the horizontal height of the fixed shaft seat is greater than the limiting clamping rod.

[0011] Through the above technical solution, it is ensured that after the external support frame and the internal support frame are merged, there will be no conflict between the positions of the fixed shaft seat and the limit rod, and it is ensured as much as possible that the external support frame and the internal support frame can fit each other, making it convenient for firefighters to hold them with one hand.

[0012] Furthermore, the rotating support mechanism includes a supporting sleeve arranged on the outer wall of the circular ring on one side of the external support frame and the internal support frame, one side of the supporting sleeve is fixedly connected with an arc-shaped limiting sleeve plate, the outer wall of the arc-shaped limiting sleeve plate is fixedly connected with a side water hose baffle, the inner wall of the supporting sleeve is provided with a connecting bearing, and a guide bucket is installed between one side of the connecting bearing and the inner wall of the supporting sleeve.

[0013] 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 achieved through the support shaft sleeve, the maximum opening and closing angle is limited by the arc-shaped limit sleeve, and the rotation support of the entire winding shaft rod mechanism is achieved by connecting the bearings. At the same time, when the winding shaft rod mechanism is inserted, rapid insertion can be achieved through the guide structure of the guide bucket.

[0014] Furthermore, the adjusting and blocking mechanism includes a blocking ring installed on one side of the rotating support mechanism, a plurality of fixing bolts are installed between the blocking ring and the rotating support mechanism, the top and bottom of the other side of the blocking ring are fixedly connected to a fixed rotating shaft, a blocking shell is rotatably connected to the fixed rotating shaft at the bottom of the blocking ring, a connecting pull plate is slidably connected to the inner wall of the blocking shell, and two first return springs are fixedly connected between the bottom of the connecting pull plate and the inner wall of the blocking shell.

[0015] Through the above technical solution, when the winding shaft rod mechanism needs to be pulled out or rotated, the connecting pull plate is pulled upward and the first return spring is stretched and then rotated, so that the connecting pull plate is separated from the fixed rotating shaft at the top. During subsequent sealing, the connecting pull plate is pulled to rotate, and the sealing sleeve is driven to rotate at the same time, and then the connecting pull plate is pulled 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 first return spring continuously generates tension on the connecting pull plate, thereby ensuring that the sealing sleeve can cooperate well with the sealing cover plate to achieve sealing of the winding shaft rod mechanism, so that it will not deviate during the rotation process.

[0016] Furthermore, the top of the connecting pull plate is a hook structure.

[0017] The above technical solution ensures that the hook structure at the top of the pull plate can be engaged and fixed with the fixed shaft.

[0018] Furthermore, the winding shaft mechanism includes a winding shaft sleeve slidably connected between two rotating support mechanisms, and the winding shaft sleeve is slidably connected to a built-in extension rod on the inner wall of one end close to the adjusting and blocking mechanism, and the other end of the built-in extension rod is fixedly connected to a limiting circular plate, and one end of the inner wall of the built-in extension rod is rotatably connected to a first rotating rod, and one end of the inner wall of the first rotating rod is rotatably connected to a second rotating rod.

[0019] Through the above technical solution, in the subsequent winding process, after the sealing sleeve is rotated to open, the limiting circular plate is pulled to pull out the built-in extension rod, and the first rotating rod and the second rotating rod are rotated respectively to open the right-angle structure. After the middle section of the fire hose is selected and folded into two layers, it is passed through the rolling sleeve at the corresponding position, and then the other end is wrapped around the outer wall of the reel rod sleeve. At this time, the second rotating rod is rotated to start driving the reel rod sleeve to start reeling the hose.

[0020] Furthermore, the winding isolation mechanism includes two side connecting rods and multiple connecting partitions rotatably connected to the top of the external support frame, a connecting shaft is fixedly connected between the two side connecting rods and the multiple connecting partitions, the other ends of the multiple connecting partitions are fixedly connected to the central water hose partition, and the outer wall of the connecting shaft is rotatably connected to multiple rolling sleeves.

[0021] Through the above technical solution, multiple fire hoses can be well isolated through multiple connecting partitions and two side hose baffles. At the same time, during the winding process, the hose can pass through the rolling sleeve to squeeze out the residual water in the hose, avoiding it from appearing in the wound hose.

[0022] Furthermore, the moving mechanism includes two slotted sleeves fixedly connected to the bottom of the external support frame or the internal support frame, the outer walls of the two slotted sleeves are rotatably connected to a rotating base on both sides, the bottoms of the two rotating bases are equipped with universal wheels, the tops of the two rotating bases are fixedly connected to a sliding limit shell, the inner walls of the two sliding limit shells are slidably connected to square blocks, second return springs are fixedly connected between the top sides of the two square blocks and the corresponding inner surfaces of the tops of the sliding limit shells, and connecting rods at both ends are fixedly connected between the tops of the two square blocks.

[0023] Through the above technical solution, during normal use, the movement of the entire device can be achieved through the moving mechanism. At the same time, in order to ensure the stability of winding, the connecting rods at both ends can be pulled to drive the two square blocks to move, so that the two square blocks are disengaged from the engagement of the two grooved sleeves, and then rotated to rotate the two rotating bases to a certain angle so that the planes of the two rotating bases contact the ground. At this time, the entire device is inconvenient to move, which makes it convenient to carry out winding and rotation work. At the same time, the bottom of the square block is attached to the outer wall of the grooved sleeve and continues to generate pressure. When the roller is needed later, the two rotating bases can be rotated to reset it. Under the elastic force of multiple second reset springs, the two square blocks can be stuck in the corresponding grooved sleeves to be fixed again.

[0024] The beneficial effects of the present invention are as follows: (1) The present invention realizes that the device can carry multiple fire hoses by designing a reel rod mechanism and a reel isolation mechanism, and designs an adjustment and blocking mechanism to realize the complete withdrawal of the reel rod mechanism, and realizes the rapid disassembly of multiple fire hoses. At the same time, in the subsequent reeling process, the reel rod mechanism can be used to quickly reel in, and in conjunction with the rolling sleeve, the water hose can pass through the rolling sleeve to squeeze out the residual water in the water hose, so as to avoid it appearing in the reeled water hose. At the same time, the external support frame and the internal support frame are combined, and the entire device can be pulled to move by the moving mechanism, thereby improving the efficiency of carrying the fire hose; (2) The present invention realizes the movement of the entire device by designing a moving mechanism during normal use. At the same time, in order to ensure the stability of the reeling, the universal wheel can be rotated by rotating the base so that the plane of the rotating base contacts the ground to ensure that the reeling can be rotated stably. When the device needs to be moved later, the two square blocks can be clamped in the corresponding grooved sleeves to achieve re-fixation, which is very convenient and fast.

DETAILED DESCRIPTION

[0027] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, 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 intended to limit the present invention.

[0028] like Figure 1-Figure 4 As shown, a fire hose handling device of this embodiment includes an external support frame 1 and an internal support frame 2. The external support frame 1 and the internal support frame 2 are both welded by a circular tube and a circular ring, ensuring that the external support frame 1 and the internal support frame 2 can be rotated and opened and closed through the circular ring, and support is achieved through the circular tube structure. A limited support mechanism 3 is provided between both sides of the external support frame 1 and the internal support frame 2. The limited support mechanism 3 includes a fixed shaft seat 301 fixedly connected to the outer wall of the external support frame 1 and a fixed shaft seat 301 fixedly connected to the inner support frame 2, and a support card plate 303 is rotatably connected to the fixed shaft seat 301. The support card plate 303 is rotated and clamped on the limit card rod 302 to achieve 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 the limit card rod 302, ensuring that after the external support frame 1 and the internal support frame 2 are merged, there will be no conflict in the positions of the fixed shaft seat 301 and the limit card rod 302, ensuring that the external support frame 1 and the internal support frame 2 can fit each other as much as possible, which is convenient for firefighters to hold with one hand.

[0029] like Figures 1-8 As shown, a rotating support mechanism 4 is rotatably connected between both sides of the external support frame 1 and the internal support frame 2. The rotating support mechanism 4 includes a support sleeve 401 arranged on the outer wall of the circular ring on one side of the external support frame 1 and the internal support frame 2, and an arc-shaped limit sleeve 402 is fixedly connected to one side of the support sleeve 401. The outer wall of the arc-shaped limit sleeve 402 is fixedly connected to the side water hose baffle 403, and a connecting bearing 404 is provided on the inner wall of the support sleeve 401. A guide bucket 405 is installed between one side of the connecting bearing 404 and the inner wall of the support sleeve 401. When the external support frame 1 and the internal support frame 2 are opened, the supporting sleeve 401 realizes the rotating support of the external support frame 1 and the internal support frame 2, and the arc-shaped limit sleeve 402 is used to limit the maximum opening and closing angle. The connecting bearing 404 realizes the rotating support of the overall winding shaft rod mechanism 7. At the same time, when the winding shaft rod mechanism 7 is inserted, the guide structure of the guide bucket 405 can achieve rapid insertion.

[0030] like Figures 1-8As shown, the two rotating support mechanisms 4 are fixedly connected with a blocking cover plate 5 and an adjusting blocking mechanism 6 on the side away from the external support frame 1 and the internal support frame 2 respectively. The adjusting blocking mechanism 6 includes a blocking ring 601 installed on one side of the rotating support mechanism 4, and a plurality of fixing bolts 602 are installed between the blocking ring 601 and the rotating support mechanism 4. The top and bottom of the other side of the blocking ring 601 are fixedly connected with a fixed rotating shaft 603. The blocking shell 604 is rotatably connected to the fixed rotating shaft 603 at the bottom of the blocking ring 601. The inner wall of the blocking shell 604 is slidably connected with a connecting pull plate 605. Two first reset springs 606 are fixedly connected between the bottom of the connecting pull plate 605 and the inner wall of the blocking shell 604. When the winding shaft mechanism 7 needs to be pulled out or the winding shaft mechanism 7 needs to be rotated, the connecting pull plate 606 is pulled upward to release the spring. The plate 605 stretches the first return spring 606 and then rotates, so that the connecting pull plate 605 is separated from the fixed rotating shaft 603 at the top. During subsequent sealing, the connecting pull plate 605 is pulled to rotate, and the sealing sleeve 604 is driven to rotate at the same time, and then the connecting pull plate 605 is pulled to stretch the first return spring 606 to clamp the other end of the connecting pull plate 605 on the fixed rotating shaft 603 at the top. The first return spring 606 continuously generates a pulling force on the connecting pull plate 605, thereby ensuring that the sealing sleeve 604 can cooperate well with the blocking cover plate 5 to achieve the blocking of the winding shaft rod mechanism 7, so that it will not deviate during the rotation process. The top of the connecting pull plate 605 is a hook structure, which ensures that the hook structure on the top of the connecting pull plate 605 can be engaged and fixed with the fixed rotating shaft 603.

[0031] like Figures 1-10 As shown, a winding shaft mechanism 7 is slidably connected between the two rotating support mechanisms 4. The winding shaft mechanism 7 includes a winding shaft sleeve 701 slidably connected between the two rotating support mechanisms 4. The winding shaft sleeve 701 is slidably connected to a built-in extension rod 702 on the inner wall near one end of the regulating and blocking mechanism 6. The other end of the built-in extension rod 702 is fixedly connected to a limited circular plate 703. One end of the inner wall of the built-in extension rod 702 is rotatably connected to a first rotating rod 704. One end of the inner wall of the first rotating rod 704 is rotatably connected to a first rotating rod 704. The second rotating rod 705, in the subsequent reeling process, rotates to open the blocking sleeve 604, pulls the limiting circular plate 703 to pull out the built-in extension rod 702, rotates the first rotating rod 704 and the second rotating rod 705 respectively, so that the right-angle structure is opened, selects the middle section of the fire hose and folds it into two layers, passes it through the rolling sleeve 805 at the corresponding position, and then the other end is wrapped around the outer wall of the reel rod sleeve 701, and then the second rotating rod 705 is rotated to start driving the reel rod sleeve 701 to start reeling the hose.

[0032] like Figures 1-15As shown, the top of the external support frame 1 is rotatably connected to a winding and isolating mechanism 8, and the winding and isolating mechanism 8 includes two side connecting rods 801 and a plurality of connecting partitions 803 rotatably connected to the top of the external support frame 1, and a connecting shaft 802 is fixedly connected between the two side connecting rods 801 and the plurality of connecting partitions 803, and the other ends of the plurality of connecting partitions 803 are fixedly connected to a central water hose partition 804, and the outer wall of the connecting shaft 802 is rotatably connected to a plurality of rolling sleeves 805, and the isolation of multiple fire hoses can be well achieved through the multiple connecting partitions 803 and the two side water hose baffles 403, and at the same time During the reeling process, the water hose can be squeezed out of the residual water in the water hose through the rolling sleeve 805 to avoid it appearing in the reeled water hose. Both sides of the bottom of the external support frame 1 and the internal support frame 2 are provided with a moving mechanism 9, and the moving mechanism 9 includes two grooved clamping sleeves 901 fixedly connected to the bottom of the external support frame 1 or the internal support frame 2, and the outer walls of the two grooved clamping sleeves 901 are rotatably connected to the rotating base 902 on both sides, and the bottoms of the two rotating bases 902 are both installed with universal wheels 903, and the tops of the two rotating bases 902 are fixedly connected to the sliding limit shells 904. The inner wall of 904 is slidably connected with a square card block 905, and the top two sides of the two square card blocks 905 and the corresponding inner surface of the top of the sliding limit shell 904 are fixedly connected with a second return spring 906. The tops of the two square card blocks 905 are fixedly connected with connecting rods 907 at both ends. During normal use, the movement of the entire device can be achieved through the moving mechanism 9. At the same time, in order to ensure the stability of the winding, the connecting rods 907 at both ends can be pulled to drive the two square card blocks 905 to move, so that the two square card blocks 905 are disengaged from the engagement of the two grooved card sleeves 901, and then rotated to make the two rotating The movable base 902 rotates a certain angle so that the planes of the two rotating bases 902 touch the ground. At this time, the entire device is inconvenient to move, which makes it convenient to carry out the winding and rotating work. At the same time, the bottom of the square clamping block 905 is attached to the outer wall of the grooved clamping sleeve 901 and continues to generate pressure. When the roller is needed later, the two rotating bases 902 can be rotated to reset it. Under the elastic force of multiple second reset springs 906, the two square clamping blocks 905 can be stuck in the corresponding grooved clamping sleeve 901 to achieve re-fixation. The winding water hose 10 is wound between the center of the outer wall of the winding shaft mechanism 7 and the winding isolation mechanism 8.

[0033] The working principle of this embodiment is as follows: when in use, the wound fire hose is opened by adjusting the sealing mechanism 6 and inserting the winding shaft mechanism 7, so that multiple fire hoses can be completely installed on the transport device. At the same time, when inserting the winding shaft mechanism 7, the winding isolation mechanism 8 needs to be rotated to a suitable position so that the winding shaft mechanism 7 can be inserted into the winding isolation mechanism 8 (the guide structure of the guide bucket 405 can achieve rapid insertion). The winding isolation mechanism 8 is used to isolate multiple fire hoses; 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 402), and then the support card plate 303 is rotated and clamped on the limit card rod 302 to support and fix 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, and the top of the combined external support frame 1 and the internal support frame 2 are pulled, and the entire 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 the fire hose reaches 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 reeled hose 10 can be pulled, and then the reeling shaft mechanism 7 is rotated to release the reeled hose 10. At the same time, in an emergency, the connecting pull plate 605 can be pulled upwards and the first return spring 606 can be stretched and then rotated to separate the connecting pull plate 605 from the fixed rotating shaft 603 at the top, and the reeling shaft mechanism 7 can be directly pulled out as a whole, so that multiple fire hoses can be quickly separated from the device and thrown out manually. When the fire hose is reeled in, the second end of the fire hose is reeled in and the second end of the fire hose is reeled in. When the fire hose is reeled in, the second end of the fire hose is reeled in and the second end of the fire hose is reeled in. When the fire hose is reeled in, the second end of the fire hose is reeled in and the second end of the fire hose is reeled in. Move to make the two square blocks 905 disengage from the engagement of the two grooved sleeves 901, and then rotate to make the two rotating bases 902 rotate a certain angle so that the planes of the two rotating bases 902 touch the ground. At this time, the entire device is inconvenient to move, which is convenient for winding and rotating. At the same time, the bottom of the square block 905 is attached to the outer wall of the grooved sleeve 901 and continues to generate pressure. When the rollers are needed later, the two rotating bases 902 can be rotated to reset them. Under the elastic force of multiple second reset springs 906, the two square blocks 905 can be stuck in the corresponding grooved sleeves 901 to achieve re-fixation. After the winding is completed, the external support frame 1 and the internal support frame 2 are combined to pull the entire device to achieve transportation.
