Description

Technical Field

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

[0002] Fire hoses are fire-fighting equipment used to deliver foam, high-pressure water, and other extinguishing agents from fire hydrants to the fire area during a fire, without the need for pre-installed pipes. Because fire hoses are relatively simple to use and offer greater rescue capability than dedicated fire extinguishers, they are highly practical fire-fighting equipment for large fires. Both ends of a fire hose have quick-connect fittings for rapid sealing and connection to fire hoses, other fire hoses, and fire nozzles, serving purposes such as water intake, hose extension, or high-pressure water spraying.

[0003] The basic requirement for fire hose reels is to fold the hose in half, with the upper and lower hose couplings offset by about 20-30 cm. Starting from the folded position, begin coiling until the hose is formed into a disc shape, with the quick-connect couplings at both ends close together but not overlapping, facilitating storage and securing in a fixed location. Currently, reeling is mainly done manually, which is inefficient and time-consuming. Utility Model Content

Detailed Implementation

[0021] The present invention will now be described in detail with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the protection scope of the present invention.

[0022] like Figure 1 As shown, this utility model provides a device for a movable fire hose reel, including: a base plate 1, a reel clamping support 5 installed at one end of the base plate 1, a reel shaft mechanism 2 fixedly installed in the middle of the base plate 1, and a leveling mechanism 4 for clamping and leveling the fire hose connected to the other end of the base plate 1.

[0023] The reel shaft mechanism 2 includes a rotating shaft mechanism fixedly installed on the base plate 1. A fire hose and a limiting ring 24 are fitted in the middle of the rotating shaft mechanism, and the limiting ring is located on both sides of the fire hose rotating shaft.

[0024] Preferably, such as Figure 2 As shown, in this utility model, the rotating shaft mechanism includes a first fixed half-shaft 21 and a second fixed half-shaft 22 mounted on the base plate 1. The first fixed half-shaft 21 and the second fixed half-shaft 22 are connected by a winding clip 25, and the fire hose is secured to the winding clip 25. Specifically, the winding clip 25 is fixedly mounted on the first fixed half-shaft 21 and the second fixed half-shaft 22 through pin holes. For example, a turntable handle 23 is installed at the end of the first fixed half-shaft 21 for rotating the rotating shaft mechanism.

[0025] The function of the wrapping clip 25 is to smoothly wrap the folded hose around the wrapping clip 25. The wrapping clip 25 consists of two wrapping rods, the spacing of which is determined according to the folding width of each hose specification. Then, the limiting ring 24 is fixed according to the width of the hose to ensure that the distance between the two limiting rings is wide enough to accommodate the hose reel.

[0026] The specific structure is as follows: Rollers 11 are installed on the base plate 1. The two front rollers are fixed to the lower front end of the base plate 1, and a universal wheel is fixed to the lower rear midpoint of the base plate 1. The three wheels can ensure that the whole device can move in any direction.

[0027] A foldable leveling mechanism 4 is installed at the front end of the base plate 1. The leveling mechanism 4 includes a U-shaped frame 43. Multiple sets of detachable upper and lower roller groups 41 and 42 are provided on the U-shaped frame 43. One end of the folded water hose passes through the lower roller group 42, and one end is set on the upper roller group 41.

[0028] Preferably, such as Figure 3As shown, in this utility model, the front end of the base plate 1 is connected to the leveling mechanism 4 via a connector 3. The connector 3 is a foldable hinge structure, which can fold and unfold the leveling mechanism 4. For example, the connector 3 includes: a rotating sleeve 31 disposed on the front edge of the base plate 1, a connecting rod 35 connected to the rotating sleeve 31, a U-shaped clip 33 installed on one side of the rotating sleeve 31, and an opening clip 32 provided on the U-shaped clip 33; a connecting rod 35 is installed on one side of the connecting rod 35. The slide rod 36 has a groove at one end, which is fitted onto the U-shaped clip 33. A spring 34 is installed at the other end of the slide rod 36. A mounting bracket 37 is vertically installed on the connecting rod 35, and the other end of the spring 34 is installed on the mounting bracket 37. When the leveling mechanism 4 rotates, the connecting rod 35 rotates, the slide rod 36 slides on the U-shaped clip 33, the spring 34 retracts, and the slide rod 36 is locked in the opening clip 32, thus retracting and fixing the leveling mechanism, making it easy to move the entire device.

[0029] The leveling mechanism 4 is fixed on the sleeve 31 and can rotate 90 degrees up and down as the sleeve 31 rotates, thus achieving the function of retracting and unfolding. The leveling mechanism 4 consists of an upper idler roller group 41, a lower idler roller group 42, and a spring bolt 43 fixed to the lower idler roller group. Its working principle is to pull up the spring bolt and lower the leveling mechanism. The upper idler roller group 41 is installed in the steel pipes at the four corners of the lower idler roller group 42. First, remove the upper idler roller group 41 and lay the lower layer of water hose flat on the lower idler roller group 42. Then, install the upper idler roller group 41 and place the upper layer of water hose on the upper idler roller group 41. The upper and lower layers of water hose pass through the upper and lower idler roller groups respectively. Under the action of the two idler rollers, the two layers of water hose are stretched and flattened, which facilitates the flat winding of the water hose on the subsequent reel shaft. When the leveling mechanism is to be retracted, the leveling mechanism 4 is lifted directly. The spring bolt moves up along the outer arc of the U-shaped clip 33 of the connecting frame 3 and falls into the opening clip 32. The entire leveling mechanism is vertically fixed on the connecting frame 3.

[0030] In addition, in this utility model, the coiled lifting mechanism 5 includes: a fixed crossbeam 51 and an arc-shaped roller frame 52. One end of the roller frame 52 is movably mounted on the fixed crossbeam 51 via a rotating shaft 55, and the other end is free to move. A rotatable roller 53 is installed at the end of the roller frame 52. A handrail 6 is fixedly installed at the rear end of the base plate 1. A spring 54 is installed on the roller frame 52. One end of the spring 54 is connected to the handrail 6, and the other end is connected to the roller frame 52. The fixed handrail 6 at the rear end of the device base plate 1 facilitates pushing and pulling when moving the device. There is a fixed crossbeam 51 in the middle of the handrail 6, on which an arc-shaped idler frame 52 is connected by a sleeve and a rotating shaft 55. A rotatable idler 53 is installed at the end of the idler frame 52. There is a spring 54 on the idler frame 52 that is connected to the upper frame of the handrail 6. When the water hose is wound, when the water hose rotates clockwise on the winding card 25, the idler frame 52 pulls and exerts a counterclockwise clamping force on the reel under the spring tension, so that the water hose will be tightly wound, making the wound water hose roll more compact.

[0031] The work process is as follows:

[0032] Fold the fire hose in half first, then move the center line of the fold upwards by 20-30 cm. This way, the lower half of both ends of the hose will extend 20-30 cm beyond the upper half. Using the fire hose's thickness of 3 mm as a reference, the first loop is a disc with a thickness of 4 times. The second loop is a disc with an inner diameter equal to the first loop plus 4 times the thickness, and so on. The outer diameter of the final loop, which is the maximum diameter of the hose, is determined by adding 4 times the thickness of the previous loop's disc.

[0033] Straighten the two layers of water hose, unfold the leveling mechanism 4, and use the winding clip 25 to hold the folded part of the water hose about 20-30 cm above the middle. Start turning the turntable handle 23 clockwise to drive the reel shaft mechanism to rotate. The water hose will be wound layer by layer onto the winding clip 25. Before the water hose is wound onto the clip, it passes through the leveling mechanism 4 and the coiling mechanism 5. The limiting device on the reel shaft will coil the water hose neatly.

[0034] It will be apparent to those skilled in the art that the above specific embodiments are merely preferred embodiments of the present utility model. Therefore, any improvements or modifications that may be made by those skilled in the art to certain parts of the present utility model still embody the principles of the present utility model and achieve the purpose of the present utility model, and all fall within the scope of protection of the present utility model.
