Description

Technical Field

[0001] This utility model relates to the field of fire protection equipment technology, and in particular to a fire hose reeling device. Background Technology

[0002] The efficiency and reliability of fire hose reel devices directly affect the efficiency of fire rescue preparation.

[0003] For example, CN216549066U discloses a fire hose reeling device, including a base, a reeling frame and a support column. The top of the base is fixed with the reeling frame and the support column respectively. A motor is installed on one side of the reeling frame. The output end of the motor is connected to a clamping plate through a rotating shaft. This utility model inserts one end that passes through the cleaning frame into the slot of the reeling roller by setting a rotating shaft, spring and anti-slip pad, and operates by an electric push rod.

[0004] Although the fire hose rewinding device achieves the basic hose rewinding function, it has exposed obvious technical defects in practical applications. The fixed limiting plate cannot adapt to different hose specifications, which can easily lead to skewed winding or hose damage. In addition, the single shaft drive has no gear speed increase and lacks bearing support, resulting in obvious shaking during rotation, which affects the stability of the rewinding operation. Therefore, it is necessary to design a fire hose rewinding device to solve the above problems. Utility Model Content

[0005] The main purpose of this utility model is to provide a fire hose rewinding device, which can effectively solve the problems in the background art.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0007] A fire hose reeling device includes a support frame, with auxiliary devices fixedly connected to the front and rear right ends of the support frame, a rotating device fixedly connected to the upper left end of the support frame, and a side plate installed on the outer side of the rotating device. A control panel is fixedly connected to the left end of the side plate.

[0008] The rotating device includes a drive motor. The output end of the drive motor passes through the support frame and is fixedly connected to a small gear. A large gear is meshed with the lower part of the outer surface of the small gear. A connecting shaft is fixedly connected to the middle of the left end of the large gear.

[0010] Preferably, the upper front end of the support frame has a groove, and the front and rear right ends of the support frame are both fixedly connected to a reinforcing rod, which is symmetrically distributed front and back. The right ends of the reinforcing rods are fixedly connected to a side shell. The lower left end of the support frame and the right end of the side shell are both provided with two lockable movable wheels. The upper rear end of the support frame is fixedly connected to a handle.

[0011] Preferably, the left end of the connecting shaft is movably connected to the upper left end of the side plate via a bearing, and the rotating rod is movably connected to the support frame.

[0016] 1. In this utility model, the limiting pressure can be precisely adjusted by the cooperation of the adjusting screw of the auxiliary device and the second limiting plate. When winding hoses of different diameters or materials, the position of the second limiting plate can be adjusted by rotating the screw block to avoid loose winding due to insufficient pressure or damage to the hose due to excessive pressure, and to ensure that the hoses are neatly arranged when winding.

[0017] 2. In this utility model, the rotating device adopts a meshing transmission structure of small gear and large gear. The power transmission efficiency is optimized through the gear set. At the same time, the bearing connection between the connecting shaft and the side plate, and the interlocking movement between the rotating rod and the support frame form a stable double-axis support, which effectively reduces rotational sway, ensures uniform winding speed, and solves the problem of unstable winding operation caused by unstable transmission.

[0026] Please see Figure 1-4 This utility model provides a technical solution:

[0027] A fire hose reeling device includes a support frame 1. An auxiliary device 6 is fixedly connected to the front and rear right ends of the support frame 1. A rotating device 5 is fixedly connected to the upper left end of the support frame 1, and a side plate 9 is installed on the outside of the rotating device 5. A control panel 10 is fixedly connected to the left end of the side plate 9.

[0028] The upper front end of the support frame 1 has a groove 7. The front and rear right ends of the support frame 1 are both fixedly connected to a reinforcing rod 3, and the two reinforcing rods 3 are symmetrically distributed front and back. The right ends of the reinforcing rods 3 are fixedly connected to a side shell 4. The lower left end of the support frame 1 and the right end of the side shell 4 are both provided with two lockable movable wheels 2. The upper rear end of the support frame 1 is fixedly connected to a handle 8.

[0029] The auxiliary devices 6 are located at the front and rear of the right end of the support frame 1, and the two auxiliary devices 6 are symmetrically distributed front and back. The control panel 10 and the drive motor 51 are connected by circuit wires, and the control circuit in the control panel 10 extends to the inside of the side plate 9 and is electrically connected to the power interface of the drive motor 51.

[0030] In this embodiment, the rotating device 5 includes a drive motor 51. The output end of the drive motor 51 passes through the support frame 1 and is fixedly connected to a small gear 52. A large gear 54 is meshed with the lower part of the outer surface of the small gear 52. A connecting shaft 53 is fixedly connected to the middle of the left end of the large gear 54. A rotating rod 55 is fixedly connected to the middle of the right end of the large gear 54. A first limiting plate 56 is fixedly connected to the right end of the rotating rod 55. A front upper rod 57 and a rear lower rod 58 are fixedly connected to the front and middle parts of the right end of the first limiting plate 56, respectively. The drive motor 51 is fixedly connected to the upper left end of the support frame 1. The left end of the connecting shaft 53 is movably connected to the upper left end of the side plate 9 through a bearing. The rotating rod 55 is movably connected to the support frame 1. The length of the front upper rod 57 is the same as the length of the rear lower rod 58.

[0031] With the above scheme: the drive motor 51 is fixed to the upper left end of the support frame 1, and its output end passes through the support frame 1 and connects to the pinion 52. The pinion 52 meshes with the large gear 54. The left and right ends of the large gear 54 are respectively connected to the connecting shaft 53 and the rotating rod 55. The right end of the rotating rod 55 is provided with a first limiting plate 56, on which are fixed an upper front rod 57 and a lower rear rod 58 of equal length. The left end of the connecting shaft 53 is connected to the side plate 9 through a bearing. The rotating rod 55 moves through the support frame 1. After starting the drive motor 51, the power... The power is transmitted from the small gear 52 to the large gear 54, which drives the connecting shaft 53, the rotating rod 55 and the first limiting plate 56 to rotate. This causes the upper front rod 57 and the lower rear rod 58 to form a rotational trajectory to wind the hose. The meshing transmission between the small gear 52 and the large gear 54 ensures stable power transmission. The bearing connection between the connecting shaft 53 and the side plate 9 and the interlocking movement between the rotating rod 55 and the support frame 1 ensure that the rotating device 5 rotates smoothly. The equal length design of the upper front rod 57 and the lower rear rod 58 makes the hose winding more even and avoids skewing.

[0032] In this embodiment, the auxiliary device 6 includes a connecting plate 61. An adjusting screw 65 is threadedly connected to the middle of the right end of the connecting plate 61. A screw block 64 is fixedly connected to the right end of the adjusting screw 65. The left end of the adjusting screw 65 is movably connected to the second limiting plate 62 via a bearing. A pressure rod 63 is fixedly connected to the upper left end of the connecting plate 61. The connecting plate 61 is fixedly connected to the support frame 1. The second limiting plate 62 is movably connected to the outside of the pressure rod 63 and the connecting plate 61. The length of the pressure rod 63 is less than the length of the connecting plate 61.

[0033] Through the above scheme: the auxiliary device 6 is fixed to the support frame 1 by the connecting plate 61, the pressure rod 63 and the connecting plate 61 form a hose channel, and the second limiting plate 62 is sleeved on the outside of the two. The rotating screw block 64 drives the adjusting screw 65 to rotate. The second limiting plate 62 moves axially along the pressure rod 63 by means of a threaded movable connection. The bearing connection ensures that the rotation of the screw does not drive the limiting plate to rotate, thereby realizing the limiting pressure adjustment of the hose. When winding, the hose passes between the pressure rod 63 and the connecting plate 61. The second limiting plate 62 restricts its lateral displacement to ensure neat winding. The position adjustment of the second limiting plate 62 is realized by the screw block 64 and the adjusting screw 65 to adapt to different specifications of hoses and winding requirements. The two auxiliary devices 6, which are symmetrically distributed at the front and rear, work together to limit the hose evenly from both sides and prevent the hose from tilting or stacking when winding.

[0034] It should be noted that this utility model is a fire hose reeling device. When it is necessary to reel in the fire hose, the operator first starts the drive motor 51 through the control panel 10. The output end of the drive motor 51 drives the pinion 52 to rotate. The pinion 52 meshes with the large gear 54, thereby transmitting power to the large gear 54. When the large gear 54 rotates, it drives the connecting shaft 53 and the rotating rod 55 to rotate synchronously. The first limiting plate 56 at the right end of the rotating rod 55 rotates accordingly. The front upper rod 57 and the rear lower rod 57, which are fixed to the right end of the first limiting plate 56, are also affected. Rod 58 forms a rotational trajectory for winding the fire hose. During hose winding, auxiliary device 6 plays a crucial role in limiting and adjusting. The hose passes between pressure rod 63 and connecting plate 61. The second limiting disc 62 is fitted over the outside of pressure rod 63 and connecting plate 61 to limit the hose and prevent it from shifting during winding. If it is necessary to adjust the limiting force or adapt to different hose specifications, the adjusting screw 65 can be rotated by screw block 64. The adjusting screw 65 drives the second limiting disc 62 to move left and right on pressure rod 63, thereby changing the position of the hose. The limiting pressure, two auxiliary devices 6 symmetrically distributed at the front and rear of the right end of the support frame 1, simultaneously limit the hose, ensuring that the hose is neatly arranged during the winding process. The left end of the connecting shaft 53 of the rotating device 5 is connected to the side plate 9 through a bearing. The rotating rod 55 moves through the support frame 1, ensuring the stability of the rotation of the rotating device 5. The front upper rod 57 and the rear lower rod 58 are of the same length, making the structure of the wound hose more uniform and preventing the hose from skewing during winding. In addition, the movement and fixing of the device are also designed to be convenient. The lockable movable wheel 2 is set at the lower left end of the support frame 1 and the right end of the side shell 4, which makes it convenient for the device to be moved when needed. The wheel can be locked after reaching the designated position. The handle 8 at the upper rear end of the support frame 1 makes it easy for the operator to push the device. The reinforcing rod 3 and the side shell 4 enhance the structural stability of the device. During the entire winding process, the control panel 10 and the drive motor 51 are connected by circuit. The operator can control the start, stop and speed of the drive motor 51 through the control panel 10, thereby controlling the speed and tightness of the hose winding, ensuring that the winding work is carried out safely and efficiently.
