Description

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a hose reel drum for a fire hydrant,

As a conventional fire hose reel device, for example, a device disclosed in Patent Document 1 (Korean Patent No. 10-1107025) has been proposed.

According to Patent Document 1, as shown in Fig. 6, the fire hydrant F includes a housing H, a horseshoe R housed in the housing H, and a hose reel R fixed to the housing H A hinge member 10 pivotable for exposure or embedding of the hosiery R and a fire hose 20 wound around the hosier R. [

The housing H is provided with a door H1 and is usually installed in a building wall or in an external exposure system.

The fire hose 20 is connected to the raw water hose 23 connected to the fire water source water pipe buried (or exposed) in the wall and housed in the housing H, using a tough material to prevent puncture or breakage. The raw water hose 23 is provided with a valve 25 to open the fire hose 23 and perform a fire fighting operation.

7 and 8, the hosiery R includes a central shaft member 30, a revolving member 40, disks 50A and 50B, and a relay member 60 which are mutually coupled.

The two disks 50A and 50B to which the hollow 50a is fitted and coupled to the both end stopping rods 41A and 41B of the revolving member 40 are arranged in a radial direction symmetrically about the center shaft member 30 The tension member 51 includes a sleeve 51A having an inner surface contacting the inner surfaces of the disks 50A and 50B at both ends thereof and a sleeve 51A contacting the inner surfaces of the sleeves 51A and 51B at both ends of the tension member 51, And a bolt 51B screwed to the two disks 50A and 50B to which the two disks 50A and 50B are fixed.

However, due to such a fastening structure, both ends of the sleeve 51A must be internally threaded, and in particular, each of the sleeves 51A is individually fastened to the disks 50A and 50B so that when the hose is unwound or wound, The sleeve 51A can not catch the twisted yarns 50A and 50B, and the twisted yarns 50A and 50B can not be twisted.

As another conventional technique for preventing this, Patent Document 2 (Korean Patent No. 10-1042038) has been proposed.

The hose reel 200 of Patent Document 2 includes a reel 210, an elbow unit 280, and a pipe 290, as shown in Figs. 9 and 10.

The reel 210 includes a first rotating plate 211, a second rotating plate 212, a steel bar 213, and a rotary bushing 214.

The first rotating plate 211 and the second rotating plate 212 are formed in a disk shape, for example. The first and second rotary plates 211 and 212 formed in a disc shape are coupled to each other by steel bars 213. The first and second rotary plates 211 and 212 are spaced apart from each other to receive the hose 205 .

The rotary bushing 214 is coupled to the rotational center of the first rotary plate 211 and the rotary bushing 214 is rotatably coupled to the elbow unit 280 to be described later.

The elbow unit 280 includes an elbow tube 240 and a connection tube 250. In addition, the elbow unit 280 may further include an air valve 260.

The rotary bushing 214 is rotatably mounted on an outer circumferential surface of one side of the elbow pipe 240 arranged in parallel with the lower plate 120 of the digesting body 100, Lt; / RTI >

A connecting pipe 250 is rotatably coupled to an inner circumferential surface of the one side of the elbow pipe 240 to which the rotary bushing 214 is rotatably coupled. The connecting pipe 250 is formed in an elbow shape. The hose 205 is coupled to the coupling pipe 250 via a coupling.

The connection pipe 250 rotates about the elbow pipe 240 by the rotation of the first and second rotation plates 211 and 212 and the water supplied to the elbow pipe 240 flows through the connection pipe 250 to the hose 205, .

In particular, the bobbin shown in Figs. 10 and 11 is composed of a plurality of steel bars 213 and a disc 213a for welding and fixing the steel bars 213 at predetermined intervals. The disk 213a serves as a reinforcing member for holding the steel bar 213 in a twisted state.

Both ends of each steel bar 213 are bent in the direction toward the center of the rotation plates 211 and 212.

However, since the other bent portion of the steel bar 213 is fastened by the fastening element of the bolt and the nut in contact with the inner surface of the first and second rotary plates 211 and 212, the disc 213a is prevented from interfering with the other- The space S is formed between the outer surface of the circular plate 213a and the inner surface of the other bent portion 213 '.

Since the structure is such that the nut is pushed into the space S and fastened with bolts from the outside, the productivity is very low because the assembly and disassembly are performed in a narrow place.

Since the circular plate 213a is located between the both ends of the steel bar 213, the connecting pipe 250 can not be disposed at the central position between the first and second rotary plates 211 and 212, The winding position must be done at the center.

Therefore, when the fire hose is wound while the connection pipe 250 is attached to the inner surface of the first rotary plate 211 or the second rotary plate 212 as much as possible, the hose is wound from one side to the other side, As shown in FIG. 6, the connection pipe 250 is wound toward one side of the center and then wound on the other side without being wound on the other side, so that the fire hose can not be released properly , The long fire hose can not be detected and can be rolled up to bulge up.
