Abstract

The utility model belongs to the construction tools in the power industry, and in particular relates to a multifunctional insulating ladder for power transmission and transformation construction. The multifunctional insulating ladder comprises a low ladder (1), elastic stop dogs (2), a pull rope (3), a pulley (4), an extension ladder (5) and countersunk screws (10), wherein an elasticity folding mechanism (6) is respectively and fixedly arranged at two sides of the upper end of the extension ladder (5) by the countersunk screws (10); each elasticity folding mechanism (6) is provided with a rotating shaft (7); the rotating shaft (7) is hinged with a ratchet shaft bracket (12); a ratchet shaft (8) is mounted on the ratchet shaft bracket (12); a unidirectional rotating ratchet (9) is arranged on the ratchet shaft (8) in a penetrating way; one end of the pull rope (3) is fixed on the pulley (4) below the extension ladder (5) and above a cross beam, and the other end of the pull rope (3) is wound on the pulley (4) below the lower ladder (1) and above the cross beam; two elastic stop dogs (2) are arranged below the cross beam on the extension ladder (5); and two sides of the top end of the extension ladder (5) are provided with insulation hooks (11). When the multifunctional insulating ladder for the power transmission and transformation construction is moved, the ladder can be pulled to move by using the unidirectional rotation of the ratchet, the labor intensity of moving is reduced.

Description

Construction of power transmission and transformation is terraced with multifunction insulating
Technical field
The utility model belongs to the power industry construction equipment, and particularly a kind of construction of power transmission and transformation is terraced with multifunction insulating.
Background technology
Common extension ladder is in the process of stretching out, the operator need to hold up ladder on one side, spurring rope on one side stretches out ladder, it is very inconvenient to operate, and carrying carrying also relatively requires great effort, especially insulation, guarantee constructor's safety need often be moved and need to the ladder that uses in the power industry construction.
Summary of the invention
The purpose of this utility model is to overcome above-mentioned technical deficiency, provides a kind of simple in structure, easy to use, and the construction of power transmission and transformation that can carry carrying is terraced with multifunction insulating.
The technical scheme that the utility model technical solution problem adopts is: construction of power transmission and transformation comprises descending stair with the multifunction insulating ladder, flexible block, stay cord, pulley, stretch out ladder, sunk screw, be characterized in stretching out terraced both sides, upper end and fix a spring folding mechanism with sunk screw respectively, spring folding mechanism is provided with rotating shaft, rotating shaft is hinged the ratchet pedestal, fill ratchet shaft at the ratchet pedestal, install the ratchet of single direction rotation on the ratchet shaft, top rail at descending stair all is equipped with pulley with stretching out on the terraced lower transverse beam, stay cord one end is fixed on the pulley that stretches out on the terraced lower transverse beam, on the pulley on the other end winding descending stair top rail, stretch out and establish two flexible blocks below the crossbeam on the ladder, be provided with insulating hanger in the both sides, top of stretching out ladder.
The beneficial effects of the utility model are: construction of power transmission and transformation directly leans against on the wall with the multifunction insulating ladder, the pulling rope will stretch out ladder and stretch out, in the climbing process, avoid the downslide of ladder by the single direction rotation of ratchet, move the single direction rotation that also can utilize ratchet when carrying and haul the ladder walking, reduced the labour intensity that carrying is carried.
Description of drawings
Specify with embodiment below in conjunction with accompanying drawing.
Fig. 1 is construction of power transmission and transformation multifunction insulating ladder structural front view.
Fig. 2 is the left side view of Fig. 1.
Among the figure, the 1-descending stair; The 2-flexible block; The 3-stay cord; The 4-pulley; 5-stretches out ladder; 6-spring folding mechanism; The 7-rotating shaft; The 8-ratchet shaft; The 9-ratchet; The 10-sunk screw; The 11-hook; 12-ratchet pedestal.
The specific embodiment
Embodiment, with reference to accompanying drawing 1,2, construction of power transmission and transformation is made with insulation materials with the multifunction insulating ladder is whole, and insulating ladder 5 slides at descending stair 1 inboard slideway.The bottom crossbeam upper and lower terraced 1 that stretches out ladder 5 is equipped with respectively pulley 4 on the crossbeam topmost, one end of stay cord 3 is fixed on and stretches out ladder 5 bottom on the pulley 4 on the crossbeam, stay cord 3 other ends are wrapped in descending stair 1 topmost on the pulley 4 on the crossbeam, stretch out on ladder 5 the crossbeam two flexible blocks 2 are housed, flexible block 2 snaps on the crossbeam of descending stair 1 and locates.Stretch out the both sides, upper end of ladder 1 and fix a spring folding mechanism 6 with sunk screw 10 respectively, spring folding mechanism 6 is provided with rotating shaft 7, rotating shaft 7 is hinged ratchet pedestal 12, at ratchet pedestal 12 dress ratchet shafts 8, install the ratchet 9 of single direction rotation on the ratchet shaft 8, be provided with insulating hanger 11 in the both sides, top of stretching out ladder 5.
Construction of power transmission and transformation with the use procedure of multifunction insulating ladder is: during use, with the ladder rested against the wall, pulling stay cord 3, ratchet 9 single direction rotation on wall rolls, and stretches out terraced 5 parts and stretches out and arrive the precalculated position, flexible block 2 is stuck on the crossbeam of descending stair 1 to locate, firmly one press ladder, folding 90 degree of ratchet pedestal 12 cantilever arms of elastic foldable mechanism 6 forward the ladder opposite side to, and ladder normally contacts with wall, and ratchet 9 can roll along the wall single direction rotation and descend.When carrying, flexible block 2 is unclamped, stretching out ladder 5 retracts, when the ladder extension is retracted, ladder can be overturn, its opposite side is contacted with wall, ratchet 9 rolls at the ground single direction rotation, haul the ladder walking and get final product, do not constructing by in the wall situation, available hook 11 hangs over ladder on circuit or the cross-arm and gets final product.
