Description

Technical Field

[0001] The utility model relates to the technical field of fire-fighting equipment, in particular to a fire hose reel stand. Background Technique

[0002] The full name of the fire hose reel is "fire hose reel", which is composed of a valve, an input pipeline, a hose, a spray gun, etc., and can spray fire extinguishing agent during the process of quickly unfolding the hose. High-rise buildings such as high-class hotels, important office buildings, commercial buildings, exhibition buildings, and comprehensive buildings of Class I buildings should be equipped with fire hose reels. The hose reels are divided into water, dry powder, and foam hose reels according to the fire extinguishing agent they convey. However, during the use of the current fire hose reel stand, since the outer surface of the fire hose gets wet and damp in the later stage of use, it is very easy to adhere to impurities. Directly squeezing and winding the hose will not only make the surface of the fire hose unclean, but also the impurities will rub against the surface of the hose during winding, thus causing damage to the hose and affecting its service life. Therefore, we propose a fire hose reel stand to solve the above problems. Content of the Utility Model

[0003] Aiming at the deficiencies of the prior art, the utility model provides a fire hose reel stand, which solves the problems raised in the above background technique.

Specific implementation mode

[0019] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative work shall fall within the protection scope of the present invention. Embodiment

[0020] As Figure 1 And Figure 2 shown, a fire hose reel rack proposed in an embodiment of the present invention includes a support frame 1. Two brackets 2 are fixed on the top of the support frame 1. A rotating shaft 3 is rotatably connected between the two brackets 2 through a bearing. A reel roller 4 is fixed on the surface of the rotating shaft 3. Two support plates 5 are fixed on the top of the support frame 1. A reciprocating lead screw 6 is rotatably connected between the two support plates 5 through a bearing. A reciprocating guide block 7 is threadedly connected to the surface of the reciprocating lead screw 6. The reciprocating guide block 7 slides above the support frame 1. A transmission component 8 for driving the rotating shaft 3 and the reciprocating lead screw 6 to rotate synchronously is arranged above the support frame 1. A cleaning component 9 is arranged between the two support plates 5. Universal self-locking wheels 10 are fixed at the four corners of the bottom of the support frame 1. A push handle 11 is fixed on the top of the support frame 1. When the hose is being wound up, one end of the hose passes through the cleaning component 9 and the reciprocating guide block 7 and is fixed to the reel roller 4. The motor is started to drive the reel roller 4 to rotate. With the cooperation of the transmission component 8, when the rotating shaft 3 rotates, the reciprocating lead screw 6 can be driven to rotate at the same time. When the reciprocating lead screw 6 rotates, the cleaning component 9 can be driven to rotate. Therefore, when the hose is being wound up, the impurities on its surface can be cleaned first, and then it can be evenly wound around the surface of the reel roller 4.

[0021] As Figure 5As shown, there is another way of the transmission assembly 8 for driving the rotating shaft 3 and the reciprocating screw 6 to rotate synchronously in the utility model, which mainly includes a driving sprocket 13 fixed on the surface of the rotating shaft 3, and a driven sprocket 14 is fixed on the surface of the reciprocating screw 6. The driving sprocket 13 and the driven sprocket 14 are connected by a chain 15. When in use, the driving sprocket 13 and the driven sprocket 14 are driven by the chain 15, so when the starting motor drives the rotating shaft 3 to rotate, the reciprocating screw 6 can be driven to rotate at the same time.

[0022] like Figure 2 As shown, in some embodiments, the transmission assembly 8 includes a driving wheel 801 fixed on the surface of the rotating shaft 3, and a driven wheel 802 is fixed on the surface of the reciprocating screw rod 6. The driving wheel 801 and the driven wheel 802 are connected by a belt 803. When in use, the driving wheel 801 and the driven wheel 802 are transmitted by the belt 803, so that when the starting motor drives the rotating shaft 3 to rotate, the reciprocating screw rod 6 can be driven to rotate at the same time.

[0023] like Figure 1 , Figure 3 and Figure 4As shown, in some embodiments, the cleaning component 9 includes four T-shaped shafts 901 rotatably connected to two support plates 5 through bearings. Driven gears 907 are fixed on the surfaces of the T-shaped shafts 901, and a driving gear 908 is fixed on the surface of the reciprocating lead screw 6. The driven gears 907 are all meshed with the driving gear 908, so that when the reciprocating lead screw 6 rotates, the two circular brushes 904 can be driven to rotate in opposite directions, which helps to save production costs. Conical blocks 902 are fixed inside the conical grooves opened at one ends of the T-shaped shafts 901. Two round rods 903 are arranged above the support frame 1, and circular brushes 904 are fixed on the surfaces of the round rods 903. Springs 905 are fixed inside the counterbores opened at both ends of the two round rods 903. The other ends of the springs 905 are all fixed with moving rods 906. Connecting rods 909 are fixed on one side walls of the moving rods 906, which facilitates the operator to move the moving rods 906 and then remove the circular brushes 904. The moving rods 906 slide inside the counterbores opened in the corresponding round rods 903 respectively, and one side walls of the conical blocks 902 are respectively fixedly connected to the corresponding moving rods 906. During use, when the T-shaped shafts 901 rotate, through the cooperation of the conical blocks 902 and the moving rods 906, the round rods 903 can be driven to rotate. After the round rods 903 rotate, the circular brushes 904 will be driven to rotate. Therefore, the impurities on the surface of the hose can be cleaned. When the circular brushes 904 need to be replaced, only need to operate the two moving rods 906 to move towards the middle position at the same time. After the moving rods 906 move, the conical blocks 902 can be driven to separate from the T-shaped shafts 901. Then the round rods 903 can be removed. Finally, the circular brushes 904 can be separated from the round rods 903 and replaced. During installation, repeat the above operations. When the conical blocks 902 are aligned with the T-shaped shafts 901, release the moving rods 906. At this time, under the action of the compressed springs 905, the round rods 903 can be limited and installed.

[0024] As Figure 1 As shown, in some embodiments, a cross plate 12 is fixed between the two support plates 5. A guide groove adapted to the reciprocating guide block 7 is opened at the top of the cross plate 12, which plays a role in limiting. When the reciprocating lead screw 6 rotates to drive the reciprocating guide block 7 to move back and forth, the reciprocating guide block 7 can be prevented from rotating synchronously with the reciprocating lead screw 6.

[0025] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
