Description

DETAILED DESCRIPTION OF THE INVENTION [Technical Field of the Invention] The present invention relates to a cable holder in an automatic wire drawing device.

[Technical background of the invention]

Conventionally, cables to be laid on electrical circuits inside a ship that are being outfitted have been manually extended by many workers. Using this method of line extension poses safety problems and requires a large number of workers. In addition, the work was delayed, and
There were times when I was required to perform unreasonable tasks due to the need for other outfitting work.

The present applicant has developed an automatic wire stretching device as shown in FIGS. 1 and 2 to solve the above-mentioned problems.

The device disclosed above has the configuration shown in FIGS. 1 and 2. That is, in FIG. 1, an endless tension rope 2 having a downward running portion 2a parallel to the tray 1 is provided above the tray 1 provided along the electric path, and the length of the tension rope 2 is the same as the length of the tray 1. A plurality of cable retainers 3 are suspended and fixed by ropes 4 at equal intervals in a portion having a length approximately equal to . Near both ends of the tray 1, take-off machines 5 and 6 for driving the tension ropes 2 are provided, respectively. The pulling machines 5 and 6 have a pair of endless belts arranged opposite to each other, and are driven by sandwiching a rope between their opposing running parts.

In addition, the fixed portion omitted in FIG.
Rope guides 7 are installed at intervals through which ropes 4 for suspending and supporting the running section 2a can pass. 5' indicates the control panel of the take-up machine.

In the above configuration, the cable retainer 3 is
It has the configuration shown in the figure. That is, a receiver 9 for receiving a signal from a transmitter, which will be described later, is attached to one side of the casing 8 attached to the rope 4, and a solenoid 10 controlled by the receiver 9 is attached to the other side. . The output shaft 10a of the solenoid has one end fixedly fixed to a shaft 11 rotatably provided on both sides of the housing end, and the other end of a link 12 is pivotally connected. One end of each link 13 is fixed to the end of the shaft 11 that protrudes from the bottom surface of the casing, and the other end of the link 13 has its head engaged in an arcuate groove 14 on the inner bottom surface of the casing 8. pin 15 is fixed, and pin 1
A cable gripping plate 16 is attached to the lower end of each cable. Although not shown, a spring force in the protruding direction is applied to the output shaft 10a of the solenoid.

In the automatic wire drawing apparatus having the above configuration, wire drawing is performed as follows. First, the supply drum 17 is placed at one end of the electric path, and the tip of the cable C pulled out from the supply drum 17 is supported by one of the cable supports 3. This support is provided by the gripping plate 16 of the cable support 3.
A cable is inserted between them, and the cable is gripped by the spring force. In this state, feed is applied to the tension rope 2 and the cable is pulled out. The next cable supporter is engaged with the pulled out cable in the same manner as described above. Thereafter, the cables are successively suspended from the tension rope 2 and extended along the electrical circuit. Note that the rope 4 suspending the cable supporter 3 passes between the vanes while rotating the impeller of the rope guide 7, and the extended rope is supported on the semicircular concave curved surface of the upper surface of the impeller engagement part. and run. Therefore, the tension rope 2 is maintained substantially straight while bearing the weight of the suspended cable.

When the wire extension is completed as described above, a signal is sent by the transmitter to energize the solenoid of each cable supporter 3, opening the gap between the grip plates 16 against the spring force, and allowing the cable to fall. .

As described above, according to the above-mentioned apparatus, the wire can be stretched without inputting input, so that the safety of the wire stretching work is improved and a large amount of labor can be saved in the work.

[Problems with background technology]

In the conventional automatic wire stretching apparatus described above, the cable must be attached to the cable supporter manually. Therefore, if the cable is attached to the support at a high place or in a narrow place, there is a drawback that the safety and workability of the work deteriorate.

[Purpose of the invention]

The present invention was made based on the above-mentioned circumstances, and an object of the present invention is to obtain a cable support device for use in an automatic wire stretching device, to which a cable can be attached without manual work.

[Summary of the invention]

The present invention includes a housing, a receiver housed in the housing, a solenoid energized by a signal input to the receiver, an output shaft of the solenoid, and an actuator connected to the output shaft. a pair of levers provided in the housing so as to be rotatable around an axis parallel to the advancing and retracting direction of the output shaft and to which a spring force is applied in a direction to open the lower ends thereof; and upper ends of these levers. a pair of links of equal length, each of which has one end connected to each other, and whose other end is connected by a pin that engages with a long hole provided in the actuating plate in the direction in which the actuating plate moves forward and backward; A cable grip plate is attached to the lower end facing surface via a spring so as to be slidable in a direction perpendicular to the lever rotation axis, and a cable grip plate is attached to the upper surface of the casing so as to be rotatable about an axis perpendicular to the advancing and retracting direction of the actuating plate. The above object is achieved by constructing a cable supporter with a bell-crank-shaped actuation lever, one end of which is engaged with a long hole in an end of the actuation plate protruding from the housing.

[Embodiments of the invention]

In FIG. 3, where the same parts as in FIG. 2 are given the same reference numerals, the output shaft 10a of the solenoid 10 is
An actuating plate 18 having two upper and lower plate members 18a is fixed. The cable grip plate 16 is attached to the lower ends of a pair of levers 20 rotatably attached to two support plates 19 provided across the housing 8 about an axis 30 parallel to the output axis 10a of the solenoid 10. It is installed as explained below. Further, one end of a link 21 having the same length is connected to the upper end of the lever 20, and a pin 22 connecting the other ends of the links is connected to the upper end of the lever 20.
is engaged with a long hole 23 provided in the plate-like member 18a of the actuating plate 18 and elongated in the forward and backward direction of the output shaft 10a. Note that a spring 24 applies a spring force below the fulcrum of the lever 20 in the direction of opening the lower ends of the lever. In addition, the cable grip plate 1
6 has its back shaft 16a slidably engaged with the lower end of the lever 20 perpendicular to the lever rotation axis, and a spring 25 is installed between the lever 20 and the cable grip plate 16. .

Furthermore, a bell crank-shaped actuation lever 26 is pivotally attached to the upper surface of the casing 8, and its upper end faces an actuation roller 28 fixed to a fixed portion (not shown) by a support frame 27. In addition, support frame 2
Reference numeral 7 is composed of a U-shaped main frame 27a and a movable frame 27b that can be slid and positioned relative to the main frame 27a, and the position of the actuating roller 28 can be adjusted. Further, the lower end of the actuation lever 26 is engaged with a long hole 29 provided at the end of the actuation plate protruding from the housing 8 .

In the support device of the present invention having the above structure, by providing the operating roller 28 at the point where the cable C is to be gripped, the cable can be gripped automatically without manual intervention. That is, the roller 2 is placed at a position where the cable C and the tension rope approach each other.
8 is installed, and the device of the present invention is sent to the position of the roller 28 by driving the tension rope with the lower ends of the lever 20 being open. Then, the operating lever 26
The upper end of the lever 26 is pushed down by the roller 28, and the lower end of the lever 26 rotates while pulling out the actuating plate 18 from the housing 8. As a result, the connecting pin 22 between the links 21 that is engaged with the elongated hole 23 of the actuating plate 18 is also driven in that direction. The movement of the pin 22 causes the lever 20 to perform the following movements: That is, at the start of movement, the lever 20 is rotated about the support shaft for the support members 19, 19 in a direction to open the lower ends thereof,
The maximum opening occurs when the links 21, 21 are in a straight line, and the opening gradually decreases thereafter. Therefore,
If the cable and the grip plates 16 are made to meet at the maximum opening, the cable is gripped between the grip plates 16 by the series of movements of the levers 20.

Next, in order to separate the cable C from the supporter of the present invention, a signal is sent by the transmitter to energize the solenoid 10, and the output shaft 10a is moved backward. This causes the lever 20 to move in the opposite direction to that described above, causing the cable to fall and detach at its maximum opening. In addition,
During this separation, the lower end of the lever 20 moves on the circumference, so that the cable is removed more quickly than in the conventional case shown in FIG. Further, a spring force is applied to the cable gripping plate 16 to push the cable C, and since the lever 20 rotates around the shaft 30 to make a circular movement, when the cable gripping plates 16 are opened, the gripping plate The cable gripping surface 16 acts to push the cable downward in the figure, allowing the cable C to fall off reliably.

Furthermore, since the cable gripping plate is equipped with the spring 25, the device of the present invention can be used for a fairly wide range of cable diameters.

〔Effect of the invention〕

As is clear from the above, according to the support device of the present invention, the cable can be gripped automatically without any manual effort, so even if the cable is attached to the support device at a high place, It can be safely attached even in a narrow place.
