Abstract
Description
The present invention relates to a footrest for a pole-lifting and lowering steel which is mounted on a pole and can move up and down the pole.
Generally, the electric cable network is composed of the processing electric cable, the feeder cable, the return cable, and the facilities attached thereto, and supplies electric power to the electric vehicle from the substation.
At this time, if a problem occurs in the electric cable line or inspection is required, the operator steps up or down the bolt provided on the electric pole. However, the surface area of the bolt was so small that when the worker moved up and down for a long time, there was a problem.
In order to solve this problem, there has been disclosed a "platen work support plate" of Korean Registered Patent No. 10-0323861 (registered on Mar. 26, 2002).
In the conventional electric foot work support plate, an anti-loose coupling nut is coupled to an outer end of a bolt integrally formed with a holder formed in a substantially U-shaped holder, and a connection The rear end of the connection forms an inclined surface at an appropriate angle, and an elastic member made of a spring or rubber, which is resiliently mounted on the fixing plate, is attached to the operation plate. And a foot plate having a plurality of non-slip protrusions formed thereon is integrally fixed to the front end of the connection, so that the foot plate is normally folded to the upper side of the holder, and when the foot plate is used, It was configured to expand and use.
Therefore, it was possible to prevent a safety accident that a worker falls in Jeonju. However, there is always a problem in that people other than the worker can move up and down the pole because they are always on the pole. Also, since it is installed only at a certain height or higher for the safety of the passengers, auxiliary tools such as a ladder are required to move up and down the pole, and therefore, there is a problem that the user always has to carry it.
SUMMARY OF THE INVENTION The present invention has been made to solve the above problems, and it is an object of the present invention to provide a method and apparatus for preventing an operator from slipping and falling, And can prevent safety accidents by preventing a general person from ascending and descending to and from the mainland, and is capable of carrying and detaching and attaching easily.
In order to achieve the above object, according to an embodiment of the present invention, there is provided a foot plate main body including a foot portion to be fitted to a pin mounting hole of a pole and a foot portion to be pushed by a worker on the outside of the fitting portion, A lever member rotatably coupled to the footrest portion so as to protrude upward and pushed when the operator steps on the footrest portion, a link member slidably moved in the fitting portion in the axial direction of the fitting portion in accordance with rotation of the lever member, And a diameter-enlarged portion provided between the link member and the fitting portion, the length of which is increased or decreased according to the sliding movement of the link member.
Wherein the enlarged diameter portion includes a link supporting portion supported by the link member, a fitting supporting portion spaced apart from the link supporting portion and supported by the fitting portion, and a connecting portion connecting the link member and the fitting supporting portion, As shown in FIG.
The enlarged diameter portion may be formed of a material having an elastic force so as to maintain the initial shape according to the sliding movement of the link member.
And an elastic member that is compressed when the lever member rotates to elastically support the lever member.
According to the present invention, when the lever member is rotated, it is fixed to the pin mounting hole of the electric pole by the enlarged diameter portion, so that it can be fixed without using a separate tool, so that it can be easily installed on the electric pole, It is possible to prevent the foot plate main body from being detached from the pin mounting hole of the electric pole.
In addition, it is possible to attach and detach the footsteps of Jeonju subway and subway in Jeonju, so it can be installed at low places of Jeonju, so the worker can move up and down in Jeonju without using ancillary equipment and prevent workers from slipping in Jeonju, And it is possible to prevent safety accidents because it is possible to prevent a general person from going down and descending in Jeonju.
