Description
Technical field
The present invention relates to electric power first-aid apparatus field, particularly a kind of electric power first-aid ladder.
Background technology
At present, each electric power supplying unit, when the daily maintenance of its transformer station and emergency maintenance, is carried electric power first-aid ladder by substation equipment maintenance and repair staff and carries out concrete operations.But existing electric power first-aid ladder tends to take up larger space, not readily portable.Additionally, in use, often there is the potential safety hazard outwards skidded off in the lower end of existing electric power first-aid ladder.And when electric power first-aid personnel need to use other instrument in repairing midway, need to get off from ladder voluntarily, climb up the ladder with instrument the most again, which increase the workload of electric power first-aid personnel, have a strong impact on operating efficiency.In place of this is the deficiencies in the prior art.
Summary of the invention
The technical problem to be solved in the present invention is, for above-mentioned weak point, it is provided that the technical scheme of a kind of electric power first-aid ladder, the program is easy to carry, and is prevented from outwards skidding off of electric power first-aid ladder lower end.Additionally, this programme also can avoid the inconvenience of the upper and lower ladder of repair personnel, this can reduce the labour intensity of substation equipment maintenance and repair staff, improves the operating rate of maintainer.
In order to solve above-mentioned technical problem, the present invention provides following a kind of electric power first-aid ladder, including the first montant be arrangeding in parallel and the second montant, is connected by one group of cross bar between two montants, and each cross bar is hinged with the first described montant and the second montant respectively；Being respectively equipped with one between each adjacent cross bar and montant can the positioning component of folding；Also including a connection piece, one end of connector is fixed on the first montant, and the other end of connector is provided with hanger；The lateral wall of the second montant lower end be provided with described hanger with the use of hook I.
Wherein, it is hinged between cross bar and montant and forms quadrangle one by one.
Wherein, positioning component can folding, i.e. can open and close.When positioning component is closed, can be used for spacing adjacent cross bar and montant, make cross bar will not relatively rotate with montant, thus can ensure that stability when whole repairing ladder uses.
Additionally, in view of the unstability of quadrangle, when positioning component is in open mode, each cross bar of the present invention can relatively rotate with montant, each cross bar can be adjusted to heeling condition, thus taking up room of the present invention can be reduced, it is simple to carry and deposit.More practical.
Additionally, the use of connector, can carry out spacing by the lower end of this repairing ladder, thus repairing ladder can be limited to specific distance, can effectively prevent rushing to repair ladder lower end and outwards skid off, safety in utilization is higher.
Described positioning component includes the one end location bar with hook II, and with described hook II with the use of locating ring, locating ring is separately positioned on adjacent cross bar and montant away from one end of hook II with location bar, and location bar is hinged on corresponding cross bar or arbitrary montant away from one end of hook II.During use, adjusting the relative position of each cross bar and montant, hang on locating ring by hook II afterwards, positioning component and the cross bar at two ends thereof and montant, three surrounds a triangle, and again in view of the stability of triangle, the stability that the present invention uses is higher.
Described cross bar includes a cross bar I and multiple cross bar II, and cross bar I is positioned at the top of each cross bar II, middle part one curved portions of cross bar I.When this repairing ladder is leaned on utility poles, can carry out spacing by curved portions, thus strengthen the Stability and dependability that the present invention uses.
For preventing two montants from the most outwards skidding off, it is provided with skid resistant course in the bottom of the first montant and the second montant.
Skid resistant course uses rubber layer.
Present invention additionally comprises a rope, the lower end of the second montant is fixed in one end of this rope, and the other end of rope is fixed with one for holding the chest of instrument by a fixed pulley, and described fixed pulley is fixed on the upper end of the second montant.Substation equipment maintenance and repair staff can pass through chest and fixed pulley, in advance required instrument is delivered to operating position, more practical.
The quantity of described hanger is three, and three hangers are distributed along the axis direction of connector.During use, can select to use arbitrary hanger according to needs, i.e. can regulate the distance that repairing ladder is limited, increase the flexibility used.
Described connector is STAINLESS STEEL CHAINS or iron chains.
Compared with prior art, it is an advantage of the current invention that:
(1) each cross bar of the present invention is hinged with the first described montant and the second montant respectively, and between each adjacent cross bar and montant, be respectively equipped with one can the positioning component of folding, wherein positioning component can folding, i.e. can open and close, when positioning component is closed, can be used for spacing adjacent cross bar and montant, make cross bar will not relatively rotate with montant, thus can ensure that stability when whole repairing ladder uses.
(2) it is hinged between cross bar and the montant of the present invention and forms quadrangle one by one, when positioning component is in open mode, unstability in view of quadrangle, each cross bar of the present invention can relatively rotate with montant, each cross bar can be adjusted to heeling condition, thus taking up room of the present invention can be reduced, it is simple to and carry and deposit, more practical.
(3) present invention additionally comprises a connection piece, one end of connector is fixed on the first montant, the other end of connector is provided with hanger, the lateral wall of the second montant lower end be provided with described hanger with the use of hook I, during use, hanger on connector can be walked around an object, such as electric pole, hang over afterwards on hook I, thus this repairing ladder is limited in a certain distance, can effectively prevent from rushing to repair ladder outwards to skid off, increase the Stability and dependability that the present invention uses.
(4) present invention additionally comprises a rope, the lower end of the second montant is fixed in one end of this rope, the other end of rope is fixed with one for holding the chest of instrument by a fixed pulley, described fixed pulley is fixed on the upper end of the second montant, during use, substation equipment maintenance and repair staff can pass through chest and fixed pulley, in advance required instrument is delivered to operating position, thus the inconvenience of the upper and lower ladder of repair personnel can be avoided, this can reduce the labour intensity of substation equipment maintenance and repair staff, improves the operating rate of maintainer.
As can be seen here, the present invention compared with prior art, has prominent substantive distinguishing features and significantly progress, and its beneficial effect implemented also is apparent from.
