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, carries electric power first-aid ladder by substation equipment maintenance and repair staff and carries out concrete operations.But existing electric power first-aid ladder often occupies larger space, is not easy to carry.In addition, 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 are when rushing to repair midway and needing to use other instrument, need to get off from ladder voluntarily, and then climb up the ladder with instrument, which increase the workload of electric power first-aid personnel, have a strong impact on operating efficiency.This is the deficiencies in the prior art part.
Summary of the invention
The technical problem to be solved in the present invention is, for above-mentioned weak point, provide a kind of technical scheme of electric power first-aid ladder, the program is easy to carry, and can prevent outwards skidding off of electric power first-aid ladder lower end.In addition, this programme also can avoid the inconvenience of the upper and lower ladder of repair personnel, and this can reduce the labour intensity of substation equipment maintenance and repair staff, improves the operating rate of maintainer.
In order to solve the problems of the technologies described above, the invention provides following a kind of electric power first-aid ladder, comprise the first montant and the second montant that be arranged in parallel, be connected between two montants by one group of cross bar, 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 comprise 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, be hinged between cross bar and montant and form quadrangle one by one.
Wherein, positioning component can folding, namely can open and closedown.When positioning component is in closed condition, can be used for spacing adjacent cross bar and montant, cross bar and montant can not be relatively rotated, thus stability when can guarantee whole repairing ladder use.
In addition, in view of the unstability of quadrangle, when positioning component is in open mode, each cross bar of the present invention and montant can relatively rotate, and each cross bar can be adjusted to heeling condition, thus can reduce of the present invention taking up room, and are easy to carry and deposit.Comparatively practical.
In addition, the use of connector, can be undertaken spacing by the lower end of this repairing ladder, thus repairing ladder can be limited to specific distance, and effectively can prevent rushing to repair terraced lower end and outwards skid off, safety in utilization is higher.
Described positioning component comprises the backstay of one end with hook II, and with described hook II with the use of locating ring, locating ring and backstay are separately positioned on adjacent cross bar and montant away from one end of hook II, and backstay is hinged on corresponding cross bar or arbitrary montant away from one end of hook II.During use, adjust the relative position of each cross bar and montant, hang on locating ring afterwards by hook II, the cross bar at positioning component and two ends thereof and montant, three surrounds a triangle, and again in view of leg-of-mutton stability, the stability that the present invention uses is higher.
Described cross bar comprises 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, undertaken spacing by curved portions, thus strengthen the Stability and dependability of the present invention's use.
For preventing two montants from use outwards skidding off, be provided with skid resistant course in the bottom of the first montant and the second montant.
Skid resistant course adopts rubber layer.
The present invention also comprises a rope, and 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.Required instrument, by chest and fixed pulley, is delivered to operating position by substation equipment maintenance and repair staff in advance, comparatively practical.
The quantity of described hanger is three, and three hangers distribute along the axis direction of connector.During use, can according to needs, the arbitrary hanger of choice for use, namely 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, the invention has the advantages 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, namely can open and closedown, when positioning component is in closed condition, can be used for spacing adjacent cross bar and montant, cross bar and montant can not be relatively rotated, thus stability when can guarantee whole repairing ladder use.
(2) be hinged between cross bar of the present invention and montant and form quadrangle one by one, when positioning component is in open mode, in view of the unstability of quadrangle, each cross bar of the present invention and montant can relatively rotate, each cross bar can be adjusted to heeling condition, thus of the present invention taking up room can be reduced, and be easy to carry and deposit, comparatively practical.
(3) the present invention also 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, as electric pole, hang over afterwards on hook I, thus this repairing ladder is limited in certain distance, effectively can prevent repairing ladder from outwards skidding off, increase the Stability and dependability that the present invention uses.
(4) the present invention also 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 is by 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.
