Description

Technical Field

[0001] This utility model relates to the field of hose reel winding devices, specifically a hose reel winding device for fire protection engineering. Background Technology

[0002] Fire protection engineering mainly studies the basic knowledge and skills of fire protection regulations, fire prevention and extinguishing engineering technology, fire investigation, and fire fighting and rescue. It involves fire management, fire fighting and rescue, and fire investigation in fire departments. For example, it involves the management of fire protection facilities such as fire alarms and fire hydrants in buildings, and the rescue and investigation of the causes of fires and other accidents.

[0003] When a fire occurs, the most important thing is to extinguish it. Water is transported through pipes to the designated location to put out the fire. The main way to transport water is through pipes. Currently, fire extinguishing commonly uses water hoses. Water hoses not only have good strength, but they can also be folded and stored, making them very convenient to carry. However, after each fire drill or fire extinguishing, the unfolded water hoses need to be manually rolled up for the next use.

[0004] Currently, hose winding is generally done manually. This involves folding the hose so that the two ends are about ten centimeters apart, and then winding it up from the folded corner. Alternatively, a machine can be used to wind the hose by clamping one end and then rotating it with a shaft to wind it into a coil.

[0005] However, since water hoses are used to transport water during fires, they need to be long enough. While existing devices can quickly complete the winding process, single-end winding can easily cause the hose to become tangled when releasing the hose. Utility Model Content

[0006] Based on this, the purpose of this utility model is to provide a fire hose reel device to solve the technical problem that although existing devices can quickly complete the reeling process, the hose is easily twisted when releasing it due to single-end reeling.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a fire hose reel device, comprising an installation body, an installation plate on the top of the installation body, a second fixing head at one end of the installation body, a first fixing head on the installation plate, a traction device at one end of the second fixing head on the installation body, the traction device comprising a pair of traction rods, a connecting block on the side of the traction rods near the installation body, a connecting hole on the installation body to cooperate with the connecting block, the traction rods being hollow, and a pair of rotating shafts symmetrically arranged from top to bottom inside the traction rods. A pull rope is fitted around the rotating shaft. Both ends of the pull rope extend from the side of the traction rod near the mounting body and into the mounting body. A control device is installed inside the mounting body to cooperate with the pull rope. The control device includes two sets of winding structures. A partition is installed inside the mounting body to cooperate with the two sets of winding structures. The winding structure includes a second drive shaft and a first drive shaft, which are arranged from top to bottom. A second winding spool is installed on the second drive shaft, and a first winding spool is installed on the first drive shaft. One end of the pull rope is connected to the first winding spool, and the other end of the pull rope is connected to the second winding spool.

[0008] By adopting the above technical solution, the pull rope is pulled to the designated position by the set traction device, and then the pull rope is wound up by the control device, thereby realizing the winding up of the water hose.

[0010] By adopting the above technical solution, the coil spring is wound up when the traction device pulls, and after being pulled to the designated position, the coil spring winds up the pull rope.

[0011] The present invention is further configured such that one end of the second drive shaft extends outside the mounting body, a mounting box is provided outside the mounting body in conjunction with the second drive shaft, a ratchet disc is provided inside the mounting box, a liquid pump is provided outside the mounting box in conjunction with the ratchet disc, the liquid pump is fixedly connected to the ratchet disc, a chuck is provided on the side of the ratchet disc near the mounting body, and the chuck is fixedly connected to one end of the second drive shaft.

[0012] By adopting the above technical solution, the ratchet disc and chuck are used to limit the movement and control the reset of the coil spring, thereby controlling the winding of the pull rope.

[0013] The present invention is further configured such that a winding device is provided between the mounting body and the traction rod, the winding device including a pair of connecting side plates, the connecting side plates being disposed on the pull ropes extending from the pair of traction rods, a clamping plate being rotatably disposed between the connecting side plates, a through hole being provided on one side of the connecting side plate in cooperation with the clamping plate, a compression airbag being provided on the side of the clamping plate away from the mounting body, a second conductor being provided on the inner wall of the compression airbag, and a first conductor being provided on the clamping plate in cooperation with the second conductor.

[0014] By adopting the above technical solution, the compression airbag is used to pull the card plate into contact with the water hose, so that the first conductor and the second conductor come into contact, thereby controlling the winding of the water hose.

[0015] The present invention is further configured such that a slot is provided on one side of the card plate, and a corresponding slot is also provided on the connecting side plate. A first limiting rod is rotatably provided in the slot, and a corresponding driving device is provided in the slot in cooperation with the first limiting rod.

[0022] This invention uses a guide device to pull the rope to a designated position. Then, the two ends of the hose are connected to the first and second fixing heads respectively, causing the hose to fold. Pulling the winding device makes contact with the folded angle of the hose, thus clamping the hose. At this time, the control device controls the coil spring to rotate and wind up the hose, driving the clamping plate to move and tighten the hose for easy recovery. After the hose is wound up, the two ends of the hose can be removed from the first and second fixing heads. Attached Figure Description

[0033] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0034] The embodiments of this utility model will be described below based on its overall structure.

[0035] A fire hose reel device, such as Figure 1-9As shown, the device includes an installation body 1, with an installation plate 2 on its top. A second fixing head 4 is located at one end of the installation body 1, and a first fixing head 3 is located on the installation plate 2. A traction device is located at one end of the second fixing head 4 on the installation body 1. The traction device includes a pair of traction rods 16, with a connecting block 8 on the side of each traction rod 16 near the installation body 1. A connecting hole 9 is provided on the installation body 1 to mate with the connecting block 8. The traction rods 16 are hollow, and a pair of rotating shafts 12 are symmetrically arranged from top to bottom inside each traction rod 16. A pull rope 7 is sleeved on the pair of rotating shafts 12, with both ends of the pull rope 7 extending from the side of the traction rod 16 near the installation body 1 and extending into the installation body 1. A control device is located inside the installation body 1 to mate with the pull rope 7. The control device includes two sets of winding structures, and a partition 24 is located inside the installation body 1 to mate with the two sets of winding structures. The winding structure includes a second drive shaft 15 and a first drive shaft 16. The first drive shaft 14, the second drive shaft 15, and the first drive shaft 14 are arranged from top to bottom. A second winding shaft 25 is mounted on the second drive shaft 15, and a first winding shaft 23 is mounted on the first drive shaft 14. One end of the pull rope 7 is connected to the first winding shaft 23, and the other end of the pull rope 7 is connected to the second winding shaft 25. The pull rope 7 is wound up by the winding shaft. Simultaneously, a first limiting disc 22 is mounted on the first drive shaft 14 in conjunction with the first winding shaft 23, and a second limiting disc 22 is mounted on the second drive shaft 15 in conjunction with the second winding shaft 25. The winding spool 25 is provided with a second limiting plate 29, and the second transmission shaft 15 is provided with a coil spring 21. The coil spring 21 is located between the second limiting plate 29 and the mounting body 1. The outer ring of the coil spring 21 is connected to the inner wall of the mounting body 1. The limiting plate ensures that the pull rope 7 is in the normal winding position when the winding spool is winding the cable. At the same time, when the pull rope 7 is pulled, the coil spring 21 will rotate. After the pull rope 7 is no longer pulled, the coil spring 21 will drive the pull rope 7 to rewind and reset.

[0036] A winding device is provided between the mounting body 1 and the traction rod 16. The winding device includes a pair of connecting side plates 6, which are mounted on the pull ropes 7 extending from the pair of traction rods 16. A locking plate 5 is rotatably mounted between the connecting side plates 6. One side of the connecting side plate 6 has a through hole 13 that mates with the locking plate 5. In actual use, the through hole 13 is aligned with the hole on the locking plate 5 for installation. Rotating the rod inserted into the through hole will rotate the locking plate 5, and vice versa. A compression airbag 11 is provided on the side of the locking plate 5 away from the mounting body 1. A second conductor is provided on the inner wall of the compression airbag 11. 32. A first conductor 30 is provided on the card plate 5 in conjunction with the second conductor 32. A slot 31 is provided on one side of the card plate 5, and a corresponding slot 31 is also provided on the connecting side plate 6. A first limiting rod 10 is rotatably provided in the slot 31, and a corresponding driving device is provided in the slot 31 in conjunction with the first limiting rod 10. In actual use, by pulling the card plate 5 to the folding corner of the water hose, the squeezing air bag 11 is brought into contact with the water hose, thereby bringing the first conductor 30 and the second conductor 32 into contact. This controls the driving device to drive the first limiting rod 10 to rotate, fixing the water hose on the card plate 5. At this time, the water hose can be wound up by rotating the card plate 5.

[0037] In conjunction with the above structure, one end of the second drive shaft 15 extends outside the mounting body 1. A mounting box 18 is provided outside the mounting body 1 to cooperate with the second drive shaft 15. A ratchet disc 19 is provided inside the mounting box 18, and a liquid pump 20 is provided outside the mounting box 18 to cooperate with the ratchet disc 19. The liquid pump 20 is fixedly connected to the ratchet disc 19. A chuck 28 is provided on the side of the ratchet disc 19 near the mounting body 1, and the chuck 28 is fixedly connected to one end of the second drive shaft 15. A plurality of ratches are provided on the side of the ratchet disc 19 near the chuck 28. The chuck 28 has a number of ratchet levers 27 and a second limiting lever 26. The contact between the ratchet disc 19 and the chuck 28 is controlled by the hydraulic pump 20, thereby controlling whether the ratchet disc 19 limits the coil spring 21. In actual use, when pulled by the traction device, the ratchet disc 19 contacts the chuck 28, so that the coil spring 21 will not drive the pull rope 7 to reset. When the winding device starts the winding operation, the hydraulic pump 20 is controlled so that the ratchet disc 19 loses control of the chuck 28, so that the coil spring 21 winds up the pull rope 7.

[0038] Furthermore, a fixing cone 17 is provided at the bottom of the traction rod 16. When the traction rod 16 is pulled, the pull rope 7 is moved to a designated position, and then the position of the traction rod 16 is fixed.
