The utility model provides a present working stand can't satisfy problem large -scale, the operation of elongated arc vault face, be equipped with with the unanimous circular arc ladder of radian of the vault face of treating the operation, make when carrying out the operation on the circular arc ladder unanimous apart from vault face distance everywhere, convenience and security when having improved the operation.
Description
Technical field
The utility model is related to working stand field, more particularly to a kind of gantry ladder.
Background technology
When the work such as being riveted, welded on to the large-scale arc top surface such as aircraft, large tank case, rocket rocket body, need
The working stand with job platform is widely used, but traditional working stand is stool formula structure or stair type structure, and its is horizontal
Size is less, needs constantly mobile working ladder, and to actually used many inconvenience are brought, length especially when manipulating object,
When span is larger, although the tread of vault can be crossed in the top of the vault for treating operation overlap joint, but because vault is arc,
The tread of overlap joint is suspended from arch top face in flat, and distance of its tread apart from vault face everywhere is unequal, can not
Enough meet actual operation requirements.
Utility model content
The utility model aims to solve the problem that the deficiencies in the prior art, and provides a kind of ladder of gantry with circular arc body.
The utility model for achieving the above object, is employed the following technical solutions：A kind of gantry ladder, it is characterised in that include
Circular arc ladder and ladder, the circular arc ladder includes being located at the lower arcuate surface and the curved handrail positioned at the both sides of lower arcuate surface of bottom,
The ladder has two, and two ladders are located at respectively the lower section at the terraced two ends of the circular arc, and the bottom of the ladder is installed
There is castor, each described ladder includes two inclined treads and the rectangle support between two treads staggered relatively,
The both sides of each tread are equipped with ladder handrail, and ladder table top, the top of the tread are provided with the top of the rectangle support
Portion is concordant with the ladder table top, the two ends of the lower arcuate surface and the curved handrail respectively with two ladder table top phases
Connection.
Particularly, fence is with the ladder table top, the top of the ladder handrail is connected with the fence.
Particularly, it is provided with take-up device between the bottom of two ladders.
Particularly, the supporting lower margin being connected with the ladder that is provided with of the castor side is supported.
The beneficial effects of the utility model are：The utility model solves existing working stand cannot meet large-scale, elongated
A kind of problem of arc top surface operation, there is provided gantry ladder with circular arc ladder of convenient use, is designed with wheel, can meet
Longer working region, and the circular arc ladder consistent with the radian in the vault face for treating operation is provided with, make to carry out operation on circular arc ladder
When, convenience and security when improve operation consistent apart from vault face distance everywhere.

Specific embodiment
With reference to the accompanying drawings and examples the utility model is described in further detail：
As shown in Figure 1, 2, a kind of gantry ladder, it is characterised in that including circular arc ladder and ladder 1, the circular arc ladder includes position
Lower arcuate surface 8 in bottom and the curved handrail 3 positioned at the both sides of lower arcuate surface 8, the ladder 1 has two, two ladders
Frame 1 is located at respectively the lower section at the two ends of circular arc ladder, and the bottom of the ladder 1 is provided with castor 5, and each described ladder 1 is wrapped
Include two inclined treads 7 staggered relatively and the rectangle support 10 between two treads 7, the two of each tread 7
Side is equipped with ladder handrail 6, and the top of the rectangle support 10 is provided with ladder table top 2, the top of the tread 7 and the ladder
Table top 2 is concordant, and the two ends of the lower arcuate surface 8 and the curved handrail 3 are connected respectively with two ladder table tops 2.
Particularly, fence 9 is with the ladder table top 2, the top of the ladder handrail 6 is connected with the fence 9.
Particularly, take-up device 4 is provided between the bottom of two ladders 1.
Particularly, the supporting lower margin being connected with the ladder 1 that is provided with of the side of the castor 5 is supported.
When the utility model is used, gantry ladder is pushed into the region for treating operation, the lower margin for adjusting the side of castor 5 is supported, and is made
Gantry ladder is fixed, then climbs up ladder table top 2 from tread 7, and into circular arc ladder region, staff lies prone in the arcuate bottom of circular arc ladder
Operation is carried out to vault face on face 8.
The utility model is exemplarily described above in conjunction with accompanying drawing, it is clear that the utility model is implemented not to be received
The restriction of aforesaid way, if the various improvement that method design of the present utility model and technical scheme are carried out are employed, or without
Improvement directly applies to other occasions, within protection domain of the present utility model.
