Description

Technical Field

[0001] This utility model relates to the field of fire-fighting auxiliary equipment technology, specifically to a fire hose auxiliary laying device. Background Technology

[0002] Fire hoses, also known as water hoses, are tubular fabric belts capable of withstanding a certain amount of liquid pressure. Based on the raw materials used, they can be classified as cotton, hemp, flax, synthetic fiber lined fire hoses, etc.; based on pressure resistance, they can be classified as ordinary type and high-pressure type fire hoses. When rewinding fire hoses after use, there is a tendency for the hose to loosen to the sides, resulting in poor rewinding performance.

[0003] Existing technologies, such as the utility model with authorization publication number CN222293286U, make it less prone to wrinkling during the winding process of fire hoses.

[0004] Currently, there is a lack of an auxiliary device for laying fire hoses to facilitate the cleaning of the fire hose surface and subsequent winding. Utility Model Content

[0005] The technical problem to be solved by this utility model is to provide an auxiliary laying device for fire hoses, in which the spacing of two cleaning rollers is adjusted to automatically match fire hoses of different thicknesses and wear levels, thereby cleaning the fire hoses and facilitating subsequent winding.

[0006] This utility model achieves its invention objective using the following technical solution:

[0007] A fire hose auxiliary laying device, characterized in that it comprises: a frame that supports all components and ensures overall rigidity; a bearing-connected screw, the frame being fixedly connected to a guide rod; the screw and the guide rod forming a precision linear guide pair with a "rotation and sliding" action, allowing the cross groove to precisely rise and fall horizontally, thereby adjusting the clamping force between the two cleaning rollers and the fire hose; the cross groove being fixedly connected to symmetrical sliders, the screw being threadedly connected to the upper slider, and the guide rod passing through the lower slider; symmetrical drive gears meshing with each other, the central shafts of the symmetrical drive gears being respectively bearing-connected to the frame, and the symmetrical drive... The central shaft of the force gear is connected to the connecting rod by bearings. The drive gear rotates in opposite directions at the same speed, providing synchronous reverse power to the two cleaning rollers, realizing the dual action of "clamping + brushing". The symmetrical cleaning rollers are covered with nylon bristles. When rotating at high speed, they can brush away mud, oil stains, and chemical residues from the surface of the fire hose, preventing impurities from being rolled back into the hose reel. The central shaft of each of the symmetrical cleaning rollers is connected to the cross block by bearings. The central shaft of each symmetrical cleaning roller is connected to the corresponding connecting rod by bearings. The symmetrical driven gears are fixedly connected to the central shaft of the corresponding cleaning rollers. The symmetrical driven gears mesh with the corresponding drive gears to realize power transmission.

[0008] As a further limitation of this technical solution, the frame bearing is connected to the central shaft of the turntable, and a swivel roller is fixedly connected to the eccentric part of the turntable. The fire hose contacts the swivel roller, which causes the fire hose to swing, causing some mud, oil stains, chemical residues, etc. to fall off.

[0009] As a further limitation of this technical solution, the central shaft of the turntable is fixedly connected to a straight groove rod, the central shaft of one of the power gears is fixedly connected to a power wheel, and a circular block is fixedly connected to the edge of the power wheel. The circular block is disposed within the straight groove of the straight groove rod. The power wheel and one of the power gears are coaxially fixed, so the rotation of the gear drives the rotation of the power wheel, thereby driving the movement of the actuating roller.

[0010] As a further limitation of this technical solution, the frame is fixedly connected to the motor via a motor bracket, and the output shaft of the motor is fixedly connected to the central shaft of another power gear to provide power for cleaning the fire hose.

[0011] As a further limitation of this technical solution, the frame is equipped with wheel mounting bases at each of its four corners to facilitate device relocation.

[0012] As a further limitation of this technical solution, a counterweight is fixedly connected to one side of the frame to achieve central balance.

[0013] As a further limitation of this technical solution, the frame is fixedly connected to the adjusting motor, and the output shaft of the adjusting motor is fixedly connected to the screw. The adjusting motor provides power for the rotation of the screw, thereby adapting to belts of different thicknesses or degrees of wear.

[0014] Compared with related technologies, the fire hose auxiliary laying device provided by this utility model has the following beneficial effects:

[0015] (1) Adjust the motor drive screw to adjust the distance between the two cleaning rollers, automatically match fire hoses of different thicknesses and wear levels, and ensure that the brushing pressure is always appropriate.

[0016] (2) A single motor drives two cleaning rollers synchronously via a gear set. After clamping the fire hose, the rollers rotate in the opposite direction at high speed. Mud, oil stains, and chemical residues are brushed off within 3-5 seconds. It can be used for both recycling and laying.

[0017] (3) By using a tug roller, it achieves reciprocating swing, which drives the fire hose to swing, causing some mud, oil stains, chemical residues, etc. to fall off. Attached Figure Description

[0023] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0024] Example 1: A fire hose auxiliary laying device, comprising: a frame 4, supporting all components and ensuring overall rigidity; a bearing connecting screw 2, the frame 4 being fixedly connected to a guide rod 3; the screw 2 and the guide rod 3 forming a precision linear guide pair of "one rotating and one sliding", enabling the cross groove 15 to precisely rise and fall in the horizontal direction, thereby adjusting the clamping force between the two cleaning rollers 11 and the fire hose; the cross groove 15, fixedly connected to symmetrical sliders 14, the screw 2 threadedly connected to the upper slider 14, the guide rod 3 passing through the lower slider 14; symmetrical power gears 19, meshing with each other, the central shafts of the symmetrical power gears 19 being respectively bearing connected to the frame 4, the symmetrical... The central shaft of the power gear 19 is connected to the connecting rod 18 by bearings. The power gear 19 rotates in opposite directions at the same speed, providing synchronous reverse power to the two cleaning rollers 11, realizing the dual action of "clamping + brushing". The symmetrical cleaning rollers 11 have nylon bristles on their surface. When rotating at high speed, they can brush away mud, oil stains, and chemical residues from the surface of the fire hose, preventing impurities from being rolled back into the hose reel. The central shaft of each of the symmetrical cleaning rollers 11 is connected to the cross block 16 by bearings. The central shaft of each symmetrical cleaning roller 11 is connected to the corresponding connecting rod 18 by bearings. The symmetrical driven gears 17 are fixedly connected to the central shaft of the corresponding cleaning roller 11. The symmetrical driven gears 17 mesh with the corresponding power gears 19 to realize power transmission.

[0025] The frame 4 is fixedly connected to the motor 9 via a motor bracket, and the output shaft of the motor 9 is fixedly connected to the central shaft of another power gear 19 to provide power for cleaning the fire hose.

[0026] The frame 4 is equipped with mounting bases for wheels 7 at its four corners, which facilitates the movement of the device.

[0027] The frame 4 is fixedly connected to the adjusting motor 1, and the output shaft of the adjusting motor 1 is fixedly connected to the screw 2. The adjusting motor 1 provides power for the rotation of the screw 2, thereby adapting to belts of different thicknesses or wear levels.

[0028] The working principle of the fire hose auxiliary laying device provided by this utility model is as follows:

[0029] Based on the thickness and wear of the fire hose, the regulating motor 1 rotates, driving the screw 2 to rotate. The screw 2 moves the upper slider 14, which in turn moves the cross groove 15. The cross groove 15 moves the lower slider 14 along the guide rod 3, which in turn moves the cross block 16 and the cleaning roller 11. The cleaning roller 11 then moves the connecting rod 18, which in turn moves the cleaning roller 11 along the height direction. The cleaning roller 11 then moves the cross block 16 along the cross groove 15, and finally, the cleaning roller 11 moves the driven gear 17, thus adjusting the spacing of the cleaning roller 11. This effectively avoids winding obstacles caused by uneven fire hose thickness or wear differences. It significantly reduces the workload of firefighters and improves the overall ease of operation.

[0030] One end of the fire hose (the end connected to the fire truck or fire hydrant) is passed through the area consisting of two cleaning rollers 11. The motor 9 is then turned, driving a drive gear 19. The two drive gears 19 mesh and rotate, driving a driven gear 17, which in turn drives the cleaning rollers 11. The cleaning rollers 11 roll and clean the surface of the fire hose, effectively removing impurities and residues. This ensures that impurities do not affect the laying effect during the winding process, further improving the efficiency and safety of firefighting operations. Simultaneously, the rolling cleaning action of the cleaning rollers 11 also slightly stretches the fire hose, helping to improve the slack that may occur due to prolonged storage or use, maintaining its good tension. The fire hose can then be wound manually or using equipment.

[0031] Example 2: This example further elaborates on Example 1. The frame 4 is connected to the central shaft of the turntable 5 via a bearing, and a swivel roller 6 is fixedly connected to the eccentric part of the turntable 5. The fire hose contacts the swivel roller 6, which causes the fire hose to swing, causing some mud, oil stains, chemical residues, etc., to fall off.

[0032] The turntable 5 is fixedly connected to the central axis of a straight groove rod 10, and the central axis of one of the power gears 19 is fixedly connected to a power wheel 12. A circular block 13 is fixedly connected to the edge of the power wheel 12, and the circular block 13 is disposed in the straight groove of the straight groove rod 10. The power wheel 12 is coaxially fixed with one of the power gears 19, so the rotation of the gear drives the power wheel 12 to rotate, thereby driving the actuating roller 6 to move.

[0033] The working principle of the fire hose auxiliary laying device provided by this utility model is as follows:

[0034] When the fire hose is wound up, it is placed on the agitator roller 6. The power gear 19 drives the power wheel 12 to rotate, and the power wheel 12 drives the round block 13 to rotate while moving along the straight groove of the straight groove rod 10. The straight groove rod 10 drives the turntable 5 to rotate back and forth, and the turntable 5 drives the agitator roller 6 to swing. The agitator roller 6 causes the fire hose to shake continuously, so that the fire hose placed on the agitator roller 6 is evenly and continuously patted during the winding process, effectively removing mud, oil stains and chemical residues attached to the surface of the fire hose, ensuring the cleanliness of the fire hose.

[0035] Example 3: This example is a further elaboration based on Example 1 or 2. A counterweight 8 is fixedly connected to one side of the frame 4 to achieve central balance.

[0036] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the content of this utility model specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
