Abstract
The invention relates to a suspension device applied to overhead operation of electricity workers, and in particular relates to an insulating horizontal ladder suspension device for an electric power tower. The device comprises a shaft; the two ends of the shaft are respectively sheathed with a shaft sleeve capable of rotating around the shaft; a connecting rod is fixed on each shaft sleeve; the top of each connecting rod is bended to be in a hook shape and is used for hanging; the two ends of the shaft extends outwards; the extension parts of the shaft are respectively and fixedly provided with a ring-shaped connecting piece. Therefore, the hook-shaped tops of the connecting rods can be hung on a triangular support frame of the line iron tower, and the ring-shaped connecting pieces are fixedly connected with two ladder beams of a ladder, so that a worker can sit on the ladder to construct and overhaul the power tower, can conveniently work and is unlikely to have work fatigue.
Description
Technical field
The present invention relates to suspension arrangement during a kind of work about electric power personal height operation, particularly a kind of electric force pole tower insulated ladder suspension arrangement.
Background technology
Transmission line of electricity accounts for important position in power system, transmission line of electricity workman is mainly engaged in the work such as power transmission line construction, operation and maintenance maintenance, in these work, has and much completes on line steel tower, the height of line steel tower, substantially more than 18 meters, belongs to work high above the ground.
Current staff is in line steel tower work; all by protector protections such as safety belts; self stand or rest on line steel tower and carry out constructing or overhauling; because trackman works long hours on steel tower of being everlasting; the work of so long dependence steel tower is not only bad for operative; and easily produce work fatigue, thus there is security incident.
Summary of the invention
A kind of electric force pole tower insulated ladder suspension arrangement of the present invention, overcomes the defect of prior art, provides a kind of a kind of electric force pole tower insulated ladder suspension arrangement when high-altitude long working.
A kind of electric force pole tower insulated ladder suspension arrangement of the present invention, comprise axle, the two ends of described axle are all set with the axle sleeve that can rotate along axle, described axle sleeve is fixed with connecting rod, the top of described connecting rod be bent into hook-shaped and for hang, the two ends of described axle stretch out, the axle extended is fixed with circular connector respectively, like this, the top-hung of connecting rod is hooked on the triangle support frame of line steel tower, two terraced beams of circular connector and ladder are connected and fixed, staff just can be sitting on ladder and carry out constructing and overhauling, thus make staff's also more convenient being also not easy that work together occur work fatigue.
Described axle comprises integrated first horizontal axis, vertical axis and the second horizontal axis, described first horizontal axis and the second horizontal axis are fixed by vertical axis, described first horizontal axis and the second horizontal axis do upper and lower rotary motion relative to vertical axis center, described axle sleeve is set on the first horizontal axis and the second horizontal axis, like this, because the first horizontal axis and the second horizontal axis do upper and lower rotary motion relative to vertical axis center, just can adapt to different triangle support frames by the position adjusting the first horizontal axis and the second horizontal axis, effectively avoid because the not identical ladder that causes of triangle support frame of different line steel towers is not steady, make ladder place at grade.
The outside of described axle, axle sleeve, connecting rod, circular connector is all coated with insulated hull, insulated hull, occurs for preventing the phenomenons such as electric leakage, electrostatic.
The advantage had with prior art is: use a kind of electric force pole tower insulated ladder of the present invention suspension arrangement, staff directly can be sitting in the enterprising line operate of ladder, need not directly rest on steel tower again, be not easy to produce fatigue, avoid producing security incident, this clearly demarcated also can at different line steel towers enterprising enforcement use, simple to operate, work task efficiency can be improved, also can reduce the generation of security incident.
Accompanying drawing explanation
Fig. 1 is the structural representation of a kind of electric force pole tower insulated ladder suspension arrangement embodiment one in the present invention.
Fig. 2 is the structural representation of connecting rod in the present invention.
Fig. 3 is the structural representation of a kind of electric force pole tower insulated ladder suspension arrangement embodiment two in the present invention.
Detailed description of the invention
Below in conjunction with drawings and Examples, the specific embodiment of the present invention is described in further detail.Following examples for illustration of the present invention, but are not used for limiting the scope of the invention.
Embodiment one:
As depicted in figs. 1 and 2, a kind of electric force pole tower insulated ladder suspension arrangement, comprise axle 1, the two ends of axle 1 are all set with the axle sleeve 2 that can rotate along axle, axle sleeve 2 is fixed with connecting rod 3, the top of connecting rod 3 be bent into hook 31 and for hang, the two ends of axle 1 stretch out, the axle 1 extended is fixed with two circular connectors 5 respectively by nut 4, circular connector 5 is bolted by two semi arch connectors, and the outside of axle 1, axle sleeve 2, connecting rod 3 and circular connector 5 is all coated with insulated hull.
In the present embodiment, the top hook 31 of connecting rod 3 hangs on the triangle support frame of line steel tower, when triangle support frame is isosceles triangle, ladder place can be made at grade, circular connector 5 is connected and fixed with two terraced beams of ladder, staff just can be sitting on ladder and carry out constructing and overhauling, thus makes staff's also more convenient being also not easy that work together occur work fatigue.
Embodiment two:
As shown in Figure 3, a kind of electric force pole tower insulated ladder suspension arrangement, comprise axle and two axle sleeves 2, axle 1 comprises integrated first horizontal axis 11, vertical axis 12 and the second horizontal axis 13, first horizontal axis 11 and the second horizontal axis 13 are fixed by vertical axis 12, first horizontal axis 11 and the second horizontal axis 13 do upper and lower rotary motion relative to vertical axis 12 center, axle sleeve 2 is set on the first horizontal axis 11 and the second horizontal axis 13, axle sleeve 2 is fixed with connecting rod 3, the top of connecting rod 3 be bent into hook 31 and for hang, the end of the first horizontal axis 11 and the second horizontal axis 13 stretches out respectively, the part of extending is fixed with circular connector 5 respectively by nut 4, circular connector 5 is bolted by two semi arch connectors, first horizontal axis 11, vertical axis 12, second horizontal axis 13, axle sleeve 2, the outside of connecting rod 3 and circular connector 5 is all coated with insulated hull.
The present embodiment is when to be used in triangle support frame be non-isosceles triangle, in order to make ladder place at grade, different triangle support frames is adapted to by the position adjusting the first horizontal axis 11 and the second horizontal axis 13, effectively avoid, because the not identical ladder that causes of the triangle support frame of different line steel towers is not steady, making ladder place at grade.
The above is only the preferred embodiment of the present invention; it should be pointed out that for those skilled in the art, under the prerequisite not departing from the technology of the present invention principle; can also make some improvement and modification, these improve and modification also should be considered as protection scope of the present invention.
