Abstract

(57) [Summary] [Purpose] The cable does not bend or twist,
To provide a cable length measuring device capable of performing the length measurement and bundle winding work in a narrow space with high efficiency. [Structure] A bearing 61 is attached to a roller 607 connected to a shaft 606 of a meter 604 which measures a length from a rotation amount.
The cable 7 and the roller 6 are pressed by pressing the cable 7 with the weight of 4.
The slip between the cable and the roller No. 07 is eliminated, and the cable length is measured by the meter 604 according to the rotation amount of the roller 607. The cable whose measurement has been completed is wound up by the drum 401 of the winding drum unit 4. Since this drum 401 has a taper shape, the bundle winding can be easily removed therefrom.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a cable length measuring device for measuring a cut length of a cable used in a construction work of a telephone exchange, and more particularly to a cable length measuring device capable of simultaneously measuring a cable and winding a bundle. ..

[0002]

[Prior Art]

 In the past, in the construction work of telephone exchanges, there was no equipment suitable for cutting the in-office cable to the required length and winding it into a bundle. For this reason, (1) the cable is unwound from the cable drum, the required length is measured with a tape measure and cut, and (2) the cut cable is manually wound to facilitate connector pressure welding work. It had been.

[0003]

[Problems to be solved by the device]

 However, this requires a wide working space of about 20 m in length and 4 m in width by the method of (1), and there is a problem that the cable is bent and twisted because of winding by the method of (2). ..

An object of the present invention is to solve the above-mentioned problems and provide a cable length measuring device capable of measuring the length of a cable and winding the bundle in a narrow place without a bending tendency or twisting. Is.

[0005]

[Means for Solving the Problems]

 To this end, the present invention provides a meter for measuring length from the amount of rotation of a shaft, a roller connected to the shaft of the meter, a guide member for guiding a cable to the upper surface of the roller, and the cable for the roller. It is composed of a rotary pressing member that presses against it, a hand-wound winding drum that winds the cable pulled out from the roller and the rotary member, and enables simultaneous measurement of the cable length and winding of the bundle.

【Example】

 Embodiments of the present invention will be described below. FIG. 1 is a side view of the cable length measuring device according to the embodiment. An installation stand 1 is provided with an eyebolt 2 for a cable guide, a pipe frame 3 and the like, and a winding drum section 4 for winding a cable is attached to the pipe frame 3. A measuring unit 6 is attached to another pipe frame 5 connected to the pipe frame 3.

In this measuring unit 6, as shown in FIGS. 2 and 3, a zero reset meter 604 is attached to vertical plates 602 and 603 that rise from a bottom plate 601 that is connected to the pipe frame 5. The 0-return meter 604 returns to 0 by pressing the 0-return button 605, and measures the amount of rotation of the roller 607 fixed to the rotating shaft 606 as the measurement length. Is to have. Reference numerals 608 and 609 denote side plates as cable guides fixed to each other at predetermined intervals by bolts 610 and nuts 611, and are attached above the vertical plate 602, and the roller 607 is rotatable inside. Has become. Further, guide holes 612 and 613 are formed in the vertical direction in the upper portions of the side plates 608 and 609 where the rollers 607 are mounted. Reference numeral 614 denotes a bearing as a rotary pressing member, which is inserted between the side plates 608 and 609, and a bearing shaft 615 thereof is guided by guide holes 612 and 613 so as to be vertically movable.

As shown in FIG. 4, the winding drum portion 4 has a tapered drum 401 having a large diameter at the base and a small diameter at the tip, a collar 402 attached to the base of the drum 1, and a drum. It is provided with a hand-turning handle 404 and the like fitted to a rotating shaft 403 of 401. The rotating shaft 403 is rotatably supported on the pipe frame 3. In this winding drum unit 4, the drum 401 is rotated by turning the handwheel 404.

The eyebolt 2 is formed with a guide hole 202 (inner diameter of about 30 mm) for inserting the cable 7 at the tip of the bolt portion 201.

Now, in the work of measuring / cutting the cable 7, after pushing the 0 return button 605 of the 0 return meter 604 to return it to 0, the cable 7 is inserted into the guide hole 202 of the eyebolt 2 and the measuring unit 6 It is further inserted between the roller 607 and the bearing 614, and further fixed to the drum 401 of the winding drum unit 4 by an appropriate method. After that, when the hand-turning handle 404 of the winding drum section 4 is rotated, the cable 7 is wound around the drum 401. The cable 7 drawn from the guide hole 202 of the eyebolt 2 at the time of this winding is pressed against the roller 607 by receiving the weight of the bearing 614, so that the roller 607 corresponds to the winding length of the cable 7. The 0-return meter 604 is operated by accurately rotating by the amount. Therefore, after confirming that the measured value of the zero-reset meter 604 reaches a predetermined value, the space (point A) between the measuring unit 6 and the winding drum unit 4 is cut by air or other cutting means. With the above, a predetermined length of the cable 7 is wound around the drum 401 of the winding drum unit 4. The wound bundled cable can be easily removed from the drum 401 because the drum 401 has a tapered shape.

From the above, the cable is not bent or twisted, and since winding and length measurement are continuously performed at the same time, a wide working space is not required. Further, since the cable 7 comes into contact with the roller 607 by receiving the pressing force of the bearing 614, the sliding on the roller 607 is extremely small, and the measurement accuracy depends entirely on the accuracy of the zero reset meter 604. When 10 cables of 15m were made, the work time per one time was compared with the conventional method. It took 4 minutes and 35 seconds with the conventional method, but with this device, it took only 1 minute and 8 seconds. It is. In addition, the workability was improved because the work was reduced from three to two. The measurement error was 3 cm or less, which was an acceptable value for actual use.

[0012]

[Effect of the device]

 From the above, according to the present invention, since the work of measuring the cable for a predetermined length and winding it up is performed simultaneously and continuously, there is no bending tendency or twisting, and the cable length measurement and bundle winding are narrow. Not only can it be done in place, but it also has the advantage of greatly improving workability.
