Description

  The present invention relates to an illuminator that can be attached to an operation rod that is used when an indirect hot wire operation is performed in the state of a live wire such as a power transmission / distribution wire installed between utility poles.

  In general, when performing indirect hot-wire work with live wires on power transmission and distribution lines installed between utility poles, the operator should be away from the distribution wires so that they do not get an electric shock by touching the live wires. It is necessary to work in position. For this reason, remote operation is performed using an operation stick to which a tip tool corresponding to the work is attached (for example, Patent Document 1).

Japanese Patent Laying-Open No. 2007-82330 (see FIGS. 7 and 9)

  By the way, when a power outage occurs at night, for example, an operator must climb a power pole and perform a power detection operation to determine whether there is a power outage using an operation rod with a voltage detector attached to the distribution line. . In order to secure the illuminance necessary for this night work, the following is done.

  First of all, a projector is used so that it can be seen well over a wide range, and a power source is taken from a cigarette lighter of a vehicle so that the light on the pillar is illuminated from the ground with the light of the projector. The worker uses an auxiliary illumination lamp such as a cap lamp so that the hand can be clearly seen. Also, if necessary, a flashlight is lifted onto the pillar, and work is performed while directly illuminating the difficult-to-see parts with the flashlight.

  The cap lamp is attached to a cap or the like worn by an operator and used for the purpose of illuminating the hand, so that it cannot illuminate light with sufficient illuminance at the work site approached by a long operating rod. . For this reason, the work must be interrupted frequently, and the work must be performed while checking the work location with a flashlight, which is a very time-consuming work. Also, the flashlight, like the cap lamp, illuminates the vicinity of the hand, so if the distance to the work location approached with a long operating rod as described above is long, the work location will be sufficient. It is not possible to illuminate light with a high illuminance. In particular, when investigating faults on a pole during a wide range of power outages, it is necessary to climb up to the top of the utility pole with the high-voltage line, which is not only a time-consuming task but also has to approach the high-voltage line. Therefore, there is a problem in terms of safety.

  By the way, it is possible to save the trouble of interrupting the work and checking the work place by hanging the flashlight on the scaffolding bolt near the work place and fixing it with a bind line etc. and illuminating the work place, Fixing the flashlight is time consuming. In addition, it is necessary to adjust the place to illuminate with a flashlight every time the work location changes, and it takes time for preparation work to secure the illuminance in advance, and it takes much work time, so it is difficult to implement there were.

  In addition, depending on the work position of the worker, it may be behind the projector illuminating from the ground, and there is a problem in terms of use such that the work location approached by the operation rod may not be sufficiently confirmed.

  Further, since the work location cannot be sufficiently confirmed due to insufficient illuminance, not only does the work take a long time, but there is also a possibility of causing a human error, and there is room for improvement.

  In addition, even during the daytime, when performing indirect hot-line work in the work of shadowed parts (for example, screw tightening with the cutout lid open), 1.5 m from the work site It was difficult to do the work because it was seen from a place far away.

  Therefore, the present invention has been made in view of the above problems, and can be used not only for daytime and nighttime but also for shortening the work time while ensuring sufficient illuminance, as well as for improving safety. It is an object to provide tools.

  An illuminator according to the present invention is configured to solve the above-described problem, and is an illuminator that is detachably attached to an operation rod that includes a twist lock-type fixing portion that fixes an end tool or an adapter that connects the end tool.

After locking the tip tool or adapter, the casing is pushed and moved to the tip tool side or the adapter side by the lock member provided in the fixing portion, so that the tip tool or adapter and the lock are locked. In order to fix the casing between the timber, the abutment portion abutting on the respective tip tool or adapter and the locking member, characterized in that it comprises the said casing.

  According to the above configuration, from the irradiation part provided in the casing fixed to the twist lock type fixing part for fixing the tip tool or adapter connected to the tip of the operating rod, from the front side of the tip tool or the front side of the adapter It is possible to irradiate light to the work site. Therefore, since the distance from the tip tool or adapter located at the tip of the operation rod to the work location is short, the work location can be illuminated with light with sufficient illuminance. Absent. And when turning to the direction which wants to irradiate light, what is necessary is just to change the direction of a tip tool or an adapter in that direction, and the direction irradiated is a direction which works with a tip tool, and can work quickly. it can. Further, since the casing is provided with a groove portion for allowing the passage of the locking pin protruding in the radial direction of the fixed portion, the fixed portion is extrapolated from the tip to the operation rod side, and after the extrapolation of the casing, Since the casing can be fixed between the tip tool or adapter and the lock member by the lock member provided in the fixing portion after the tip tool or adapter is locked to the locking pin of the fixing portion, the fixing portion is There is also an advantage that the lighting fixture can be mounted without any modification.

  Further, the lighting device of the present invention is a lighting device that is detachably attached to an operation rod having a twist lock type fixing portion that fixes the tip tool or an adapter that connects the tip tool, and is close to each other. Freely switchable between a fixed state in which the operation rod is fixed to the front end portion or the fixing portion and a fixed release state in which the operation rod is separated from the fixed state and can be detached from the front end portion or the fixing portion.

Light can be irradiated to a location. Accordingly, since the distance from the tip or the fixed portion of the operating rod to the work place is short, the work place can be illuminated with light with sufficient illuminance, and it is not necessary to approach the high voltage line and irradiate light. And when directing to the direction which wants to irradiate light, what is necessary is just to change direction of a fixing | fixed part in that direction, and the direction irradiated is a direction which works with a front-end tool, and can perform work quickly. In addition, since the pair of divided portions can be fixed to the distal end portion or the fixing portion of the operating rod by being brought close to each other and hung on the distal end portion or the fixing portion of the operating rod, There is also an advantage that the lighting fixture can be mounted without any modification.

Further, a pair of upper and lower lock pieces 29 and 29 for holding the closed state shown in FIG. Therefore, by moving the pair of lock pieces 29, 29 from the lock position shown in FIG. 4A to the left side, the lock pieces 29, 29 are switched to the lock release position, and the split portions 24, 25 are separated from each other around the pin P. The movable member can be moved and released, and the split portions 24 and 25 can be held on the lock member 6C in this swinging open state. Then, after the divided portions 24 and 25 are held, the pair of lock pieces 29 and 29 are moved from the unlocked position to the locked position (see FIG. 4A), so that the divided portions 24 and 25 are locked. It can be fixed in a state of being held by 6C. In this fixed state, since the pair of divided portions 24 and 25 includes the stepped inner surfaces 27 having two different inner diameters R1 and R2, not only can the contact area be increased, but also the step 27C can lock the locking member. It is possible to reliably prevent the lighting tool S mounted on 6C from being displaced upward or rattling. Moreover, since it is the structure made to contact | abut both surfaces of the outer peripheral surface of 6 C of lock members, and the outer peripheral surface of the support part of a lock member, there also exists an advantage which can prevent loosening of a rotational lock member effectively.
