Description

Technical Field

[0001] The utility model relates to the technical field of fire-fighting devices, and particularly relates to a winding and releasing device for a fire-fighting air supply pipe. Background Art

[0002] During on-site fire-fighting and rescue operations, before entering an indoor space, fire-fighting personnel will wear a gas supply mask to avoid inhaling soot and high-temperature air. The gas supply mask is connected to an external gas supply vehicle or gas cylinder through a gas supply pipe. In actual use, a steel wire gas pipe is used as the gas supply pipe, and the length of the gas supply pipe is often more than one hundred meters. And according to the on-site situation, when the length of the gas supply pipe is not enough, it is necessary to connect and lengthen the gas supply pipe. When transporting the gas supply pipe, the gas supply pipe itself is heavy, and if the gas supply pipe is manually carried, it will consume a lot of physical strength of fire-fighting personnel. After transporting the gas supply pipe, the gas supply pipe should be quickly detached from the transport device so as to quickly connect the two ends of the gas supply pipe. After the fire-fighting and rescue operation is completed, it is necessary to recover the gas supply pipe and the fire-fighting water hose laid on the ground. When recovering the fire-fighting water hose, a water hose reel machine is used. The water hose reel machine has two output ends in the form of rollers arranged at intervals and drives the two rollers to rotate through a motor to complete the winding of the water hose. If the water hose reel machine is used to wind the gas supply pipe, due to the different materials and diameters of the water hose and the gas supply pipe, the water hose is wound and stored in a reel while the gas supply pipe is spirally stored. In order to wind the gas supply pipe spirally on the roller, it is also necessary to hold the gas supply pipe by hand to adjust the feeding direction of the gas supply pipe, and the gas supply pipe is likely to dirty the clothes of fire-fighting personnel. When using the water hose reel machine to separately store the water hose and the gas supply pipe, the overall storage operation time is relatively long. There is an urgent need for a winding, releasing and transporting device for a fire-fighting gas supply pipe that can conveniently wind and store the gas supply pipe, quickly release the whole wound gas supply pipe, and can use the output end of the water hose reel machine as power. Content of the Utility Model

[0003] The technical problem to be solved by the utility model is to provide a winding, releasing and transporting device for a fire-fighting gas supply pipe that can conveniently wind and store the gas supply pipe, quickly release the whole wound gas supply pipe, and can use the output end of the water hose reel machine as power.

[0004] To solve the above technical problems, the utility model includes a frame capable of promoting walking. The frame is rotatably connected with a first turntable and a second turntable capable of approaching and departing from the first turntable. A bearing plate with an outer diameter smaller than the outer diameters of the first turntable and the second turntable is fixedly connected to one side of the second turntable facing the first turntable. At least two jacks are arranged at intervals on the first turntable. The bearing plate is provided with insertion shafts capable of extending into the jacks. The first turntable is provided with a coupling mechanism capable of being connected to the output end of a hose reel. The frame is provided with a material blocking and separating mechanism for separating the air supply pipe wound on the bearing plate from the bearing plate when the second turntable departs from the first turntable. The material blocking and separating mechanism is provided with a material pressing component capable of pressing the air supply pipe wound on the bearing plate. The frame is provided with an adjusting mechanism capable of adjusting the feeding position of the air supply pipe when the bearing plate rotates and winds the air supply pipe.

[0005] After adopting the above structure, the rotation of the output end of the hose reel is used as the rotation power through the coupling mechanism and transmitted to the first turntable. The rotating first turntable drives the second turntable and the bearing plate to rotate through the insertion shafts. Then, the air supply pipe is conveniently spirally wound and stored on the bearing plate by operating the adjusting mechanism. The air supply pipe on the bearing plate is conveniently transported by pushing the frame. After the stored air supply pipe is transported to a designated position by pushing the frame, the second turntable is made to depart from the first turntable, and the bearing plate on the second turntable also departs from the first turntable. The material blocking and separating mechanism separates the air supply pipe on the bearing plate from the bearing plate, so as to realize the rapid release of the whole wound air supply pipe. The material pressing component ensures the posture of the air supply pipe during the transportation and spiral storage of the air supply pipe, preventing the air supply pipe from spreading.

[0006] Furthermore, a fixed seat is fixedly connected to the frame. A first rotating shaft is fixedly connected to the first turntable. The first rotating shaft is rotatably connected to the fixed seat through a bearing arranged on the fixed seat. The coupling mechanism is arranged on the side of the first rotating shaft away from the first turntable. The frame is provided with two first guide rails arranged at intervals and opposite to each other left and right. A first sliding seat is slidably connected to the first guide rail. A second rotating shaft is fixedly connected to the second turntable. The second rotating shaft is rotatably connected to the first sliding seat through a bearing arranged on the first sliding seat. A stop bar capable of abutting against the outer side surface of the first sliding seat is hinged to the first guide rail. By arranging the first guide rail and the first sliding seat, the second turntable is made to approach and depart from the first turntable by sliding the first sliding seat. When the second turntable approaches the first turntable until the insertion shafts extend into the jacks, the stop bar limits the first sliding seat.

[0007] Further, the coupling mechanism includes a coupling frame connected to the first rotating shaft. The coupling frame is provided with two long holes at intervals. A plurality of ejector rods are screwed on the upper and lower sides of the coupling frame respectively, and the ejector rods can abut against the output end of the hose reel machine inserted into the long holes. By providing the coupling frame and the ejector rods, after the output end of the hose reel machine is inserted into the long holes, the ejector rods abut against the output end of the hose reel machine to lock the position of the output end of the hose reel machine, ensuring the stability of the device during operation.

[0008] Further, the material blocking and separating mechanism includes a sleeve connected to the fixed seat. A separating claw is slidably connected to the sleeve. The separating claw has an acting end with the bottom end above the top end of the bearing plate and below the top end of the air supply pipe wound on the bearing plate. The distance from the acting end to the first turntable is greater than the width of the bearing plate. The second turntable is provided with an avoidance groove for avoiding the acting end. The sleeve is provided with a pin that can be inserted into the separating claw. The position of the separating claw on the sleeve can be locked by the pin. When the second turntable moves away from the first turntable, the air supply pipe on the bearing plate is blocked by the acting end of the separating claw and can slide off the bearing plate, so as to realize the rapid release of the whole wound air supply pipe.

[0009] Further, the pressing component includes a screw passing through the separating claw. A pressing plate is screwed to the lower part of the screw. A compression spring is sleeved on the screw, with one end abutting against the separating claw and the other end abutting against the pressing plate. The elastic pressure is applied to the air supply pipe on the bearing plate by the compression spring and the pressing plate, ensuring the posture of the air supply pipe on the bearing plate.

[0010] Further, the adjusting mechanism includes two second guide rails spaced apart and arranged oppositely left and right on the frame. A second sliding seat is slidably connected to the second guide rail. A roller for receiving the air supply pipe is rotatably connected to the second sliding seat. A push-pull rod is hinged to the second sliding seat. By holding and pushing and pulling the push-pull rod to adjust the position of the second sliding seat, the position of the roller supporting and abutting against the air supply pipe can be adjusted, so that the feeding direction of the air supply pipe can be conveniently adjusted.

[0011] Further, the frame is provided with a receiving box with an open top end. By providing the receiving box, the air supply fittings can be stored, reducing the assembly operation burden of the air supply components.

[0012] Further, the second rotating shaft is provided with a handle. By providing the handle, the first turntable, the second turntable and the bearing plate can also be rotated in a hand-cranked manner to meet various operation requirements.

[0013] In summary, the utility model has the advantages of convenient use and reasonable structure. BRIEF DESCRIPTION OF THE DRAWINGS

Detailed Embodiment

[0022] Now, the present utility model will be further described in detail with reference to the accompanying drawings and embodiments. These drawings are all simplified schematic diagrams, only showing the basic structure of the present utility model in a schematic manner, so they only show the components related to the present utility model. For the convenience of understanding, Figure 1 the left side is the left side of the present utility model, Figure 1 the right side is the right side of the present utility model. Referring to Figure 7 , the existing water hose reel machine has two spaced rollers as the output end and drives the two rollers to rotate in the same direction through a motor to complete the winding of the water hose.

[0023] Referring to Figures 1 to 6, the utility model comprises a frame 1 capable of pushing for walking, and a plurality of universal wheels with locking functions are arranged at the bottom of the frame 1. The frame 1 is rotatably connected with a first turntable 2 and a second turntable 3 capable of approaching and departing from the first turntable 2. Specifically, a fixed seat 11 is fixedly connected to the frame 1, a first rotating shaft 21 is fixedly connected to the first turntable 2, and the first rotating shaft 21 is rotatably connected to the fixed seat 11 through a bearing arranged on the fixed seat 11. Two first guide rails 12 are arranged on the frame 1 at intervals and oppositely left and right, a first sliding seat 13 is slidably connected to the first guide rail 12, a second rotating shaft 31 is fixedly connected to the second turntable 3, and the second rotating shaft 31 is rotatably connected to the first sliding seat 13 through a bearing arranged on the first sliding seat 13. A stop bar 121 capable of abutting against the outer side surface of the first sliding seat 13 is hinged to the first guide rail 12. A bearing plate 4 with an outer diameter smaller than the outer diameters of the first turntable 2 and the second turntable 3 is fixedly connected to one side of the second turntable 3 facing the first turntable 2. At least two jacks are arranged on the first turntable 2 at intervals, and the bearing plate 4 is provided with a plug shaft 41 capable of extending into the jacks. The second turntable 3 approaches and departs from the first turntable 2 by sliding the first sliding seat 13. When the second turntable 3 approaches the first turntable 2 until the plug shaft 41 extends into the jacks, the stop bar 121 limits the first sliding seat 13. Reversing the stop bar 121 can release the limit on the first sliding seat 13. A handle 311 is arranged on the second rotating shaft 31. By arranging the handle 311, the first turntable 2, the second turntable 3 and the bearing plate 4 can also be rotated in a hand-cranking manner to meet various operation requirements. An accommodating box 14 with an open top is arranged on the frame 1, and the accommodating box 14 can store air supply fittings, reducing the assembly operation burden of air supply components.

[0024] Refer to Figures 1 to 6, on the side of the first rotating shaft 21 away from the first turntable 2, there is a coupling mechanism 5 that can be connected to the output end of the hose reel machine. The coupling mechanism 5 includes a coupling frame 51 connected to the first rotating shaft 21. The coupling frame 51 is provided with two long slots 511 at intervals. On the upper and lower sides of the coupling frame 51, there are respectively screwed several ejector rods 52 that can abut against the output end of the hose reel machine inserted into the long slots 511. After the output end of the hose reel machine is inserted into the long slots 511, one end of the ejector rod 52 abuts against the output end of the hose reel machine, locking the position of the output end of the hose reel machine and ensuring the stability of the device during operation. The frame 1 is provided with a material blocking and separating mechanism 6 that separates the air supply pipe wound around the bearing plate 4 from the bearing plate 4 when the second turntable 3 moves away from the first turntable 2. The material blocking and separating mechanism 6 includes a sleeve 61 connected to the fixed seat 11. A separating claw 62 is slidably connected to the sleeve 61. The separating claw 62 has an acting end 621 whose bottom end is above the top end of the bearing plate 4 and below the top end of the air supply pipe wound around the bearing plate 4. The distance from the acting end 621 to the first turntable 2 is greater than the width of the bearing plate 4. The second turntable 3 is provided with an avoidance groove 32 for avoiding the acting end 621. The sleeve 61 is provided with a pin 63 that can be inserted into the separating claw 62. The position of the separating claw 62 on the sleeve 61 can be locked by the pin 63. When the second turntable 3 moves away from the first turntable 2, the air supply pipe on the bearing plate 4 is blocked by the acting end 621 of the separating claw 62 and can slide off the bearing plate 4, thus realizing the rapid release of the entire air supply pipe after winding.

[0025] Refer to Figure 1 , Figure 2 and Figure 6 , the material blocking and separating mechanism 6 is provided with a material pressing component 7 that can press the air supply pipe wound around the bearing plate 4. The material pressing component 7 includes a screw 71 passing through the separating claw 62. A pressing plate 72 is screwed to the lower part of the screw 71. A compression spring 73 is sleeved on the screw 71, with one end abutting against the separating claw 62 and the other end abutting against the pressing plate 72. There can be several groups of the screw 71 and the compression spring 73. The compression spring 73 and the pressing plate 72 apply elastic pressure to the air supply pipe on the bearing plate 4. The position of the pressing plate 72 can float up and down after being contacted by the air supply pipe at its bottom, ensuring the posture of the air supply pipe on the bearing plate 4 and preventing the pressing plate 72 from interfering with the air supply pipe spirally wound on the bearing plate 4. The frame 1 is provided with an adjustment mechanism 8 that can adjust the feeding position of the air supply pipe when the bearing plate 4 rotates and winds the air supply pipe. The adjustment mechanism 8 includes two second guide rails 81 spaced apart and arranged opposite to each other left and right on the frame 1. A second sliding seat 82 is slidably connected to the second guide rails 81. The second sliding seat 82 is rotatably connected to a roller 83 for receiving the air supply pipe. The second sliding seat 82 is hinged with a push-pull rod 84. The sliding direction of the second sliding seat 82 extends parallel to the axial direction of the bearing plate 4. Hold and push and pull the push-pull rod 84 to adjust the position of the second sliding seat 82, and the position of the roller 83 that supports and abuts against the air supply pipe can be adjusted, so that the feeding direction of the air supply pipe can be conveniently adjusted.

[0026] When the utility model is in use, one end of the air supply pipe is lapped on the roller 83 and wound around the bearing disc 4 for at least one circle, and the pressing plate 72 presses the air supply pipe wound around the bearing disc 4. The output end of the hose reel machine is inserted into the long strip hole 511, and the ejector rod 52 is screwed so that one end of the ejector rod 52 abuts against the output end of the hose reel machine. When the hose reel machine is used to reel the hose, the coupling mechanism 5 transmits the rotation of the output end of the hose reel machine as the rotation power to the first turntable 2, and the rotating first turntable 2 drives the second turntable 3 and the bearing disc 4 to rotate through the insertion shaft 41. Hold, push and pull the push-pull rod 84 to adjust the position of the second sliding seat 82, and the feeding position of the air supply pipe can be changed, so that the air supply pipe can be wound around the bearing disc 4 in a spiral winding manner. When it is necessary to remove the whole air supply pipe on the bearing disc 4, the stop bar 121 is toggled to release the limit on the first sliding seat 13, and the first sliding seat 13 is pulled outwards to make the second turntable 3 away from the first turntable 2, and the bearing disc 4 on the second turntable 3 also moves away from the first turntable 2. The acting end 621 of the disengaging claw 62 abuts against the air supply pipe on the bearing disc 4. As the bearing disc 4 continuously moves away from the first turntable 2, the air supply pipe on the bearing disc 4 is blocked by the acting end 621 of the disengaging claw 62 and can slide from the bearing disc 4 to the frame 1.

[0027] The above content is only an example and explanation of the structure of the utility model. Those skilled in the art of this technology can make various modifications or supplements to the described specific embodiments or use similar methods to replace them. As long as they do not deviate from the structure of the utility model or exceed the scope defined by the claims of this patent, they should all belong to the protection scope of the utility model.
