  Conventionally, as this type of work scaffold, an upper and lower mounting member, a scaffold main body on which an operator's foot is placed, and a belt connecting them are provided, and the upper and lower mounting members are provided at intervals in the vertical direction of the utility pole. Attached to the upper and lower scaffolding bolts (hereinafter referred to as “scaffolding members”) and fastened with a belt, the scaffolding body is fixed at a position between the upper and lower scaffolding members and used for work on the power pole There is what can be made (for example, see Patent Document 1).

In this work platform, the scaffold members of the power pole are provided alternately in a vertical direction (staggered), and therefore the worker can place the scaffold body at approximately the same position as one of the scaffold members. However, the work can be performed with the feet placed on the scaffold member and the scaffold main body and standing on both feet.
Utility Model Registration No. 3126299

  For example, as shown in FIG. 8, when two workers work together on a utility pole, the two workers are the main worker A who is the main subject of the work and the main worker A. Can be divided into auxiliary workers B who assist in the work, and work can be performed efficiently while sharing the work. At this time, it is desirable that the main worker A and the auxiliary worker B work as close as possible without being separated from each other. However, when the auxiliary worker B approaches the main worker A and performs the work, the main worker A's It is conceivable that the foot of the auxiliary worker is placed on the scaffold member 100 on which the foot is placed, and both feet overlap, making it difficult to perform the work.

  In order to solve this problem, it is conceivable to use a conventional work scaffold. In this case, the scaffold main body is separated from the scaffold member on which the foot of the main worker A is placed and is in a lower position thereof. It is provided at substantially the same position as the scaffold member. Therefore, when the foot of the auxiliary worker B is placed on the scaffold main body, the auxiliary worker B is separated from the main worker A, and it may be difficult to assist the main worker A.

  In addition, when attaching a conventional work scaffold to a utility pole, the upper and lower attachment members had to be bridged over the scaffold members at the top and bottom of the utility pole, and the scaffold itself was fixed by tightening the belt. It took a long time.

  The present invention has been made in view of the above circumstances, and when a plurality of workers work together on a power pole, the work can be easily performed, and the power pole can be quickly and easily attached to the power pole. An object is to provide a working scaffold.

The present invention has been made to solve the above-mentioned problems, and in order to allow the operator's feet to be placed on the scaffold body having a predetermined length , the scaffold body is spaced apart in the longitudinal direction. There is provided, removably attached to the scaffold members electric pole side, the utility pole for work scaffolding and a plurality of support portions you support the scaffold body so that the vicinity of the scaffold member, the support portion, the scaffold member A locking portion that is locked to the scaffold member, a retaining means that prevents the locking portion from being detached from the scaffold member, and a scaffold main body that does not move when the operator's feet are placed thereon. and a fixing means, in order to differentiate the engagement and disengagement direction of the support portion to the scaffold member, one of the two supporting portions adjacent in the longitudinal direction of the scaffold body, the engaging portion of one of the support portions, the other support portion It is formed in a different direction from the locking part of The means includes a first fixing means that engages with a head provided at a longitudinal end of the scaffold member and fixes the scaffold main body so as not to move, and the first fixing means is engaged with and disengaged from the head. And a second fixing means for fixing the first fixing means so that the first fixing means can be engaged with the head, and the second fixing means is supported. A shaft portion formed with a male screw that is screwed into a screw hole provided in the middle of the portion, and one end portion of the shaft portion, and the shaft portion abuts against the outer surface of the power pole by moving to the power pole side. And a contact portion .

  According to such a configuration, when the support portion is attached to the scaffold member of the utility pole, the scaffold body is supported by the support portion at a position near the scaffold member. For example, two workers on the utility pole When performing collaborative work, one worker puts his / her feet on the scaffold member, and the other worker puts his / her feet on the scaffold main body located in the vicinity of the scaffold member and can work near each other. . Therefore, it becomes easy for workers to perform collaborative work. Moreover, since this electric pole working scaffold only needs to attach a support part to a scaffold member, it can be quickly and easily attached to an electric pole.

In addition, since each of the locking portions formed in the two support portions adjacent to each other in the longitudinal direction of the scaffold main body is formed in a different direction, the scaffold main body moves greatly during the work. Moreover, it can prevent reliably that the latching | locking part of two support parts slips off from a scaffold member. Therefore, the utility pole work scaffold is double-prevented by this configuration and the retaining means.

In addition, the worker can use the work posture in which the work pole platform is fixed and used by the fixing means, and the work that the scaffold main body can move with respect to the power pole (or the scaffold member) without using the fixing means. The posture can be selected. Thus, the utility pole work scaffold is used in a state suitable for the work according to the work contents of the worker, and is useful in this respect.

Further, the first fixing means is fixed by the second fixing means in a state of being engaged with the head of the scaffold member, so that the scaffold body does not move even when the operator's foot is placed. It is fixed to the member. The utility pole work scaffold can also be used in a state where the first fixing means is released by operating the second fixing means and the scaffold main body can move within a predetermined range. Thereby, the work pole work platform can be used in a state suitable for the work according to the work content of the worker.

Further, if the utility pole for work scaffolding according to the present invention, the abutment is a plate having a curved surface having one end surface is curved to engage the curved shape of the outer surface of the utility pole, the shank axis A configuration that can rotate around can be adopted.

Further, in the utility pole work scaffold according to the present invention, the first fixing means protrudes outward from the side surface of the locking portion along the longitudinal direction of the scaffold member, and the shaft portion moves to the utility pole side. The structure provided with the protrusion part engaged with the side surface of the head part of a scaffold member is employable.

  According to the electric pole work scaffold according to the present invention, when a plurality of workers work together on the electric pole, the work can be easily performed, and the electric pole can be quickly and easily attached to the electric pole.

The end portion of the scaffold body 4 is fixed at a position near the one end portion 5 a in the longitudinal direction of each support portion 5, 5. Hereinafter, the one end portion 5a of the support portion 5 is referred to as a “base end portion”, and the end portion 5b opposite to the base end portion 5a is referred to as a “tip end portion”.

  Each of the support portions 5 and 5 includes a locking portion 6 that is detachably locked to the scaffolding bolt 3 fixed to the utility pole, and a retaining member that prevents the locking portion 6 from being detached from the scaffolding bolt 3. Means 7.

  As shown in FIG. 1, the locking portion 6 is formed in a hook shape (hook shape) and is formed at the distal end portion 5 b of the support portion 5. Moreover, this latching | locking part 6 is curvedly formed in circular arc shape, and is formed in the taper shape which the thickness becomes gradually thin as it goes to the front-end | tip of the collar.

  Of the two support portions 5 and 5 that support the scaffold body 4, the locking portion 6 of one support portion 5 is formed in a different direction from the locking portion 6 of the other support portion 5. Specifically, one locking portion 6 is formed in the direction opposite to the direction of the other locking portion 6. By doing in this way, the working scaffold 1 can engage / disengage the one locking part 6 and the other locking part 6 from / to the scaffold bolt 3 from different directions.

  As shown in FIGS. 1 and 2, the retaining means 7 includes a plate-shaped retaining member 9 that can approach and separate from the support portion 5, and a support shaft 10 that supports the retaining member 9. The retaining member 9 is formed in an elongated shape along the longitudinal direction of the support portion 5.
