Abstract
The utility model discloses a take handrail to be difficult for single ladder of turnover aims at providing one kind and moves in can making the operating personnel focus, is difficult for a take handrail to be difficult for single ladder of turnover of outside turnover. Including mobile jib and crosspiece, the mobile jib upper end is equipped with a shelves, the inboard of mobile jib is equipped with a plurality of metal quarter bends, the crosspiece sets up on the horizontal plane of metal quarter bend, the water plan position that the metal quarter bend set up the crosspiece sets up and is outstanding outside the mobile jib with the bar is reverse, leans on on the wall body, when the foot is stepped on on the crosspiece for the operating personnel when single ladder for operating personnel's centre of body weight makes operating personnel more stable to moving in the wall department, single ladder is difficult for outside turnover simultaneously.
Description
Technical field
The utility model relates to ascending a height of using in building finishing and maintenance and installation field and climbs wall ladder, more particularly, is a kind of single ladder of Armrest not prone to tip over.
Background technology
At present, when carrying out in building finishing and maintenance and installation field, need to carry out simple operation or climbing to higher position, the single ladder of general normal use or two ladder, apply more due to single terraced lighter in weight and conveniently moving, but due to single ladder be lean against on body of wall to work, and the pedal of single ladder is directly fixed on two mobile jibs, when operating personnel stand in single terraced top, because center of gravity overlaps with the pedal be directly fixed on two mobile jibs, very easily drive the outwards overturning of single ladder when health hypsokinesis.A kind of in Chinese patent literature disclosed " a kind of Anti-slipping ladder ", its publication number is " a kind of Anti-slipping ladder " in this technical scheme of CN201412021, mainly in each ladder foot of ladder, arranges a Universal sucker.No matter how are ladder placed angle and ground, and sucker can perpendicular to ground, even if ground can not be adsorbed very well sometimes, and also can, frictional force large and anti-sliding stop large because of contact area.But due to this " a kind of Anti-slipping ladder " also exist operating personnel stand in single terraced top time, because center of gravity overlaps with the pedal be directly fixed on two mobile jibs, very easily drive the defect of the outside overturning of single ladder when health hypsokinesis.
Summary of the invention
The utility model is devoted to solve in prior art and is there are operating personnel when standing in single terraced top, because center of gravity overlaps with the pedal be directly fixed on two mobile jibs, very easily drives the defect of single terraced outside overturning when health hypsokinesis.Aim to provide one can make to move in operating personnel's center of gravity, single ladder of a kind of Armrest not prone to tip over of not easily outwards overturning.
In order to solve the technical problem of above-mentioned existence, the utility model adopts following technical proposals: a kind of single ladder of Armrest not prone to tip over, comprise mobile jib and crosspiece, described mobile jib upper end is provided with top shelves, the inner side of described mobile jib is provided with some metal quarter bends, described crosspiece is arranged on the horizontal plane of metal quarter bend, described metal quarter bend arranges the horizontal plane position of crosspiece and bar oppositely arranges and protrudes from outside mobile jib, when single ladder leans against on body of wall, in operating personnel tramp with one's feet on crosspiece, the centre of body weight of operating personnel is made to move in metope place and make operating personnel more stable, single ladder not easily outwards overturning simultaneously.
As preferably, the horizontal plane of described metal quarter bend and mobile jib are the angle of 50 degree to 70 degree, and when the angle that single ladder leans against on body of wall changes in allowed band, operating personnel also can normal operating.
As preferably, the same level place of described mobile jib is equipped with bar, upper place an order ladder time make operating personnel safer and quick.
As preferably, the upper surface of described crosspiece is arc-shaped, and when single ladder leans against on body of wall with different angles time, operating personnel also can very steady standing on the arc surface of crosspiece.
Owing to adopting technique scheme, the beneficial effect of single ladder of a kind of Armrest not prone to tip over that the utility model provides is: 1. make to move in operating personnel's center of gravity; 2. not easily outwards overturning.
Accompanying drawing explanation
Fig. 1 is a kind of sectional structure schematic diagram of the present utility model;
Fig. 2 is the right TV structure schematic diagram of the utility model Fig. 1.
Detailed description of the invention
Below in conjunction with accompanying drawing and detailed description of the invention, the utility model is described in detail:
Embodiment 1
In the embodiment 1 shown in accompanying drawing 1, accompanying drawing 2, comprise mobile jib and crosspiece, described mobile jib 1 upper end is provided with top shelves 2, the inner side of described mobile jib 1 is provided with some metal quarter bends 4, described crosspiece 3 is arranged on the horizontal plane of metal quarter bend 4, described metal quarter bend 4 arranges the horizontal plane position of crosspiece 3 and bar 5 oppositely arranges and protrudes from outside mobile jib 1, the horizontal plane of described metal quarter bend 4 and mobile jib 1 are the angle of 50 degree to 70 degree, the same level place of described mobile jib 1 is equipped with bar 5, and the upper surface of described crosspiece 3 is arc-shaped.
Single ladder in use, first leans against on body of wall by the utility model, and makes crosspiece 3 comparatively near apart from metope, and then operating personnel can slam crosspiece 3 upwards by shelves upwards, also can to get a grip on the rail bar 5 with hand simultaneously, reverse operating during descending stair.
