Abstract
The invention relates to a herringbone ladder, in particular to a herringbone ladder with a handrail. The herringbone ladder comprises two ladder frames which are hinged, ladder surfaces connected on the ladder frames, a supporting plate connected on the side faces of the ladder frames and rubber pads connected at the bottoms of the ladder frames, round holes are formed in the side face of one ladder frame, sliding groves are formed in the other ladder frame on the same side, more than two round holes are formed in each of the ladder frames and the supporting plate, the supporting plate is connected with the round holes and the sliding grooves through bolts respectively, a straight plate in bolt connection with the supporting plate is arranged on the same, the handrail is arranged at the top end of the straight plate, a hook is arranged on the side face of the straight plate, and a nut is arranged on each bolt. The herringbone ladder has the advantages that when standing at a higher position of the ladder, construction personnel can adjust height of the handrail for the convenience of holding and pulling, and shaking caused by the fact that the construction personnel stands unstably when center of gravity is high can be avoided, so that potential safety hazards are eliminated.
Description
Technical field
The present invention relates to a kind of double ladder, be specially a kind of Armrest double ladder.
Background technology
Double ladder is a kind of very conventional ascending tool in construction working, because of its use time, the terraced bar of front and back and ground form an isosceles triangle, look like ' people ' word, calling ' double ladder ' thus its image.Practical double ladder has fixing double ladder and moving herringbone ladder; Fixing double ladder is that people build instrument temporarily, and movable double ladder is connected together by the top loose-leaf of two ladders, can altogether, due to its flexibility, therefore be widely used when movement.But Problems existing is: when constructor stands in ladder higher position, the position of centre of gravity of constructor is higher, does not protect accordingly again above ladder, therefore there is certain potential safety hazard.
Summary of the invention
The object of this invention is to provide a kind of Armrest double ladder guaranteeing constructor's safety.
To achieve these goals, a kind of Armrest double ladder provided by the invention, comprises two hinged ladders, the tread be connected on ladder, the rubber cushion that is connected to the gripper shoe on ladder side and is connected to bottom ladder; A described ladder side is provided with circular hole, another ladder of homonymy is provided with chute, described ladder and gripper shoe are provided with plural circular hole, described gripper shoe is connected with circular hole and chute respectively by bolt, described gripper shoe is provided with bolted straight plate with it, described straight plate top is provided with handrail, and described straight plate side is provided with hook, and described bolt is provided with nut.
Compared with prior art, the advantage of this programme is: described gripper shoe and two ladders surround a triangle, and described gripper shoe is connected with screwed hole by bolt, then fixes with nut, compared to general triangle ladder, has better stability; Be provided with rubber cushion bottom described ladder, increase the frictional force on ladder and ground, make ladder more firm; When constructor stands in ladder higher position, because position of centre of gravity is higher, easily rock, constructor can hold handrail, and described ladder and gripper shoe are provided with plural screwed hole, for regulating the height of gripper shoe, thus the height of adjustable handrail, make that constructor is more convenient to hold, more firmly stand on ladder, described hook can be used for hanging the instrument of lighter in weight or material, thus eliminates potential safety hazard.
As preferred scheme, described circular hole is screwed hole, makes the connection of bolt and ladder more firm.
As preferred scheme, described hook is bolted on straight plate, is convenient to dismounting and assembling.
As preferred scheme, described straight plate is arranged at outside chute, and when drawing ladder in, straight plate overlaps with ladder, is convenient to dismounting and the storage of straight plate and gripper shoe.
Accompanying drawing explanation
Fig. 1 is the schematic perspective view of Armrest double ladder of the present invention.
Fig. 2 is the right view of Armrest double ladder of the present invention.
Fig. 3 is the top view of Armrest double ladder of the present invention.
Detailed description of the invention
Below in conjunction with drawings and Examples, technical solution of the present invention is further illustrated;
As shown in Figure 1, Armrest 4 double ladder of the present invention, comprises ladder 1, tread 2, screwed hole 3, handrail 4, hook 5, straight plate 6, nut 7, bolt 8, rubber cushion 9, gripper shoe 10, chute 11.
As shown in Figure 1, Figure 2, Figure 3 shows, two ladders 1 are hinged, in order to realize gathering and the expansion of two ladders 1, ladder 1 arranged multiple tread 2, are surrounded by rubber cushion 9 bottom ladder 1, increase the frictional force on ladder 1 and ground, ladder 1 side is provided with multiple screwed hole 3, gripper shoe 10 is provided with corresponding screwed hole 3, the height of gripper shoe 10 can be regulated, thus the height of adjustable handrail 4, another ladder 1 of homonymy is provided with chute 11, gripper shoe 10 one end is linked together by bolt 8 and the screwed hole 3 on ladder 1, chute 11 li arranges a bolt 8, bolt 8 is connected with the other end of gripper shoe 10, straight plate 6 is connected on same bolt 8 with gripper shoe 10, straight plate 6 top is provided with the handrail 4 being parallel to ground, straight plate 6 side is connected with hook 5 by bolt 8, above-mentioned bolt 8 is all by nut 7, fixing straight plate 6 is arranged at outside chute 11, when drawing ladder 1 in, straight plate 6 overlaps with ladder 1, be convenient to dismounting and the storage of straight plate 6 and gripper shoe 10.
As shown in Figure 1, ascend a height construction time, constructor according to construction needed for concrete height, regulate the angle of ladder 1, then by regulating the height of gripper shoe 10, thus determining the height of handrail 4, being then fixed with bolt 8 and nut 7, hook 5 can be used to hang lighter instrument or material, constructability human users, meanwhile, when constructor stand on ladder higher position, handrail 4 can be held, avoid the potential safety hazard that constructor causes because of crank.
Above-described is only the preferred embodiment of the present invention; should be understood that; for a person skilled in the art; under the prerequisite not departing from structure of the present invention; some distortion and improvement can also be made; these also should be considered as protection scope of the present invention, and these all can not affect effect of the invention process and practical applicability.
