Description

Technology Field

[0001] The present invention relates to a movable platform for a utility pole that enables safe up-and-down movement of the utility pole. Background Technology

[0002] Generally, steel pipe utility poles are installed in locations where it is difficult to install concrete utility poles.

[0003] In other words, steel pipe utility poles are installed in locations where there is limited space for installing concrete utility poles and where vehicle access for installing concrete utility poles is not easy.

[0004] To work on these steel pipe utility poles, the worker proceeds with the work by moving up and down using a ladder supported at an angle on the side of the pole, a platform installed on the pole, and a safety line connecting the worker to the pole.

[0005] However, since steel pipe utility poles have a smaller outer diameter and are formed in a cylindrical shape compared to general concrete utility poles, it is difficult to securely support ladders, leading to unsafe work and causing the poles to sway during vertical movement by workers.

[0006] In addition, the work platform of the steel pipe utility pole is located at a height of 3.9m, so a ladder of about 3.5m or more must be installed. However, there is a problem in that safety accidents frequently occur when there is insufficient support from an assistant worker holding the ladder from the bottom while the worker is moving the ladder.

[0007] In addition, there is a method of climbing up by separately installing a work platform (with a spacing of 50 to 60 cm) at the bottom of the steel pipe utility pole, but there is a concern about safety accidents due to working in a confined space while installing the work platform. Also, if a small ladder (about 2 m) is installed and the work platform is installed while climbing up from the ladder, there is a problem that the installation of the work platform is considered work, making it impossible to work on the ladder. The problem to be solved

[0008] One embodiment of the present invention aims to provide a movable platform for utility poles that prevents safety accidents during the process of moving a worker up and down a steel pipe utility pole and enables safe work. means of solving the problem

[0012] The second main body can be formed as a long rod-shaped structure along the length of the utility pole while spaced apart from the other side of the utility pole.

[0013] The fixing part protrudes in a round shape from the footrest part and can be detachably inserted and fixed to the outer circumference of the utility pole.

[0014] The fixing part may include a first fixing support part that protrudes in a round shape to one side from the footrest part and supports one side of the utility pole, a second fixing support part separated into a pair that protrudes in a round shape to the other side from the footrest part with the utility pole in between and fixes the other side of the utility pole, and a clamper installed on the second fixing support part and fixing the second fixing support part separated into a pair to each other.

[0015] The second fixed support member may include a first support piece, one end of which is connected to the footrest and the other end of which protrudes in a round shape to cover a part of the outer surface of the utility pole; a second support piece, one end of which is connected to the footrest and the other end of which protrudes in a round shape to cover another part of the outer surface of the utility pole; and a clamper that fixes the first support piece and the second support piece.

[0016] The clamper may include a toggle clamp body that pressurizes and fixes the space between the first support piece and the second support piece, including a locking part installed on the first support piece and a locking hook installed on the second support piece and fixed by being caught on the locking part.

[0017] A friction pad may be attached to the inner surface that contacts the outer surface of the utility pole at the first fixed support and the second fixed support.

[0018] The friction pad may be a rubber member attached to the inner surface of the first fixed support and the second fixed support.

[0019] A sub-leg supported on the floor surface may be installed on the main body of the footrest.

[0020] The sub-leg can be installed in the shape of a bar, with one end rotatably installed on the side of the footrest body and the other end supported on the floor surface.

[0021] The sub-leg may include a first leg rotatably installed on the side of the first main body and supported in contact with the floor surface, and a second leg rotatably installed on the side of the second main body and supported in contact with the floor surface.

[0029] As illustrated in FIGS. 1 to 4, a movable platform (100) for a utility pole according to the first embodiment of the present invention comprises a platform body (10) installed in a supported state on the side of a utility pole (12) and having a plurality of platform sections installed at positions spaced apart from each other, and a fixing section (20) installed on a platform section (15) and detachably fixed to the utility pole. The utility pole (12) described below is exemplarily described as a utility pole made of steel pipe material.

[0030] The footrest body (10) is installed with a long length in the vertical direction of the utility pole (12), so that a worker can move appropriately in the vertical direction of the utility pole (12).

[0031] More specifically, the footrest body (10) includes a first body (11) installed spaced apart from one side of a utility pole (12), a second body (13) installed spaced apart from the first body (11) with the utility pole (12) in between, and a footrest part (15) that connects the first body (11) and the second body (13) and has a fixing part (20) installed thereon.

[0032] The first main body (11) can be installed in a spaced-apart state on one side of the utility pole (12) and extended in a long length in the vertical direction of the utility pole (12). The first main body (11) can be installed in a rod shape on the side of the utility pole (12) in a spaced-apart state.

[0033] The second main body (13) can be installed in a position opposite to where the first main body (11) is installed, with the utility pole (12) in between, in a state where it is extended in a long length in the vertical direction of the utility pole (12). The second main body (13) can be installed in a rod shape, spaced apart from the side of the utility pole (12).

[0034] The first main body (11) and the second main body (13) may be installed with the same or similar lengths from each other with the utility pole (12) in between. Although the first main body (11) and the second main body (13) are exemplarily described as being installed in a rod shape, they are not necessarily limited thereto, and it is also possible to appropriately modify and apply them in a polygonal column shape, etc.

[0035] These first main body (11) and second main body (13) can be fixed to a utility pole (12) while being connected to each other by a footrest (15).

[0036] The footrests (15) are installed in multiple numbers spaced apart from each other in the vertical direction of the first main body (11) and the second main body (13), so that the worker can easily move up and down during the process of working on the utility pole (12).

[0037] The footrests (15) can be installed in multiple stages, spaced apart from each other at equal intervals in the vertical direction of the first main body (11) and the second main body (13).

[0038] A fixing part (20) for fixing to a utility pole (12) can be installed on this footrest part (15).

[0039] The fixed part (20) is fixed to the utility pole (12) while installed on the footrest part (15), and can be fixed so as to be detachably fixed by the clamper (25) described later.

[0040] More specifically, the fixed part (20) may include a first fixed support part (21) that protrudes in a round shape from one side of the footrest part (15) to support one side of the utility pole (12), a second fixed support part (23) that protrudes in a round shape from the other side of the footrest part (15) with the utility pole in between to fix and support the other side of the utility pole (12) and is separated into two parts, and a clamper (25) that is installed on the second fixed support part (23) and pressurizes and fixes the separated state.

[0041] The first fixed support member (21) can be installed to support one side of the utility pole (12) by protruding at a position approximately in the center of the longitudinal direction of the footrest member (15) as a single unit.

[0042] The first fixed support member (21) may protrude in a round shape on one side of the footrest member (15) corresponding to the round outer surface of the utility pole (12).

[0043] Meanwhile, the second fixed support member (23) is formed such that the utility pole (12) is positioned between the first fixed support member (21) and the second fixed support member (23), and can be formed to support the other side of the utility pole (12).

[0044] The second fixed support member (23) can protrude in a round shape on the other side of the footrest member (15) corresponding to the round shape outer surface of the utility pole (12).

[0045] More specifically, the second fixed support member (23) may include a first support piece (23a) which is connected to the footrest member at one end and protrudes in a round shape at the other end to cover a part of the outer surface of the utility pole (12), a second support piece (23b) which is connected to the footrest member (15) at one end and protrudes in a round shape at the other end to cover another part of the outer surface of the utility pole (12), and a clamper (25) that fixes the first support piece (23a) and the second support piece (23b).

[0046] The first support member (23a) and the second support member (23b) are formed with round shapes having the same or similar curvature and are installed so as to be separably connected to each other, and can be installed so as to allow insertion of the utility pole (12).

[0047] These first support piece (23a) and second support piece (23b) can be fixed to each other by a clamper (25) while the utility pole (12) is inserted inside.

[0052] One end of the sub-leg (30) may be installed rotatably on the side of the footrest body (10), and the other end may be installed in the shape of a bar supported on the floor surface. That is, the sub-leg (30) is installed at a lower position of the footrest body (10) and may be installed to provide more stable support so that the footrest body (10) does not tip over to one side.

[0053] FIG. 5 is a schematic perspective view illustrating the state in which a sub-leg is installed according to the first embodiment of the present invention.

[0054] Referring more specifically to FIG. 5, the sub-leg (30) may include a first leg (31) rotatably installed on the side of the first main body (11) and supported in contact with the floor surface, and a second leg (33) rotatably installed on the side of the second main body (13) and supported in contact with the floor surface.

[0055] The first leg (31) is rotatably installed at the lower part of the first main body (11), and can be installed to be supported on the floor surface in the front direction of the first main body (11) when rotated.

[0056] The second leg (33) is rotatably installed at the lower part of the second body (13) and can be installed to be supported on the floor surface in the front direction of the second body (13) when rotated.

[0057] It is also possible to attach a friction member (35) for stable support to the bottom surface to the ends of the first leg (31) and the second leg (33).

[0058] The friction member (35) can be formed of a rubber material so that each of the first leg (31) and the second leg (33) is attached to the end to enable stable frictional contact with the floor surface.

[0059] Accordingly, the movable platform (100) of the present embodiment is inserted and fixed to the utility pole (12) and is stably supported on the floor surface by a sub-leg (30), allowing a worker to stably move up and down the utility pole (12) in the up and down direction using a plurality of platform parts (15), thereby enabling stable work progress without safety accidents.

[0060] As described above, the movable platform (100) of the present embodiment can be installed by fixing a platform body (10) having a plurality of platform parts (15) installed on a utility pole (12) by the fixing operation of a fixing part (20) with a toggle clamp function.
