Abstract
The utility model provides a high-safety ladder stand for an arm support, which is arranged in the middle of a crane lever in the height direction, and comprises two longitudinal rods and a plurality of pedals arranged between the two longitudinal rods in parallel. The high-safety ladder stand for the arm support in the utility model has light weight, adopts an assembling structure and is convenient to disassemble; an anti-skidding measure is adopted on the surface of the pedal, so that the safety of the ladder stand is ensured; and simultaneously the pedal design accords with international relevant standard, thus being more humanized.
Description
Technical field
The utility model relates to a kind of cat ladder, especially, relates to the cat ladder of a kind of jib with high security.
Background technology
Crane arm support mainly comprises main chord and web member two parts.Main chord constitutes the main body frame of jib, web member then between two adjacent main chords, thereby constitute a complete jib.Usually, main chord and web member are steel pipe, and it constitutes jib by being welded to each other assembly unit.
When needs carry out the jib dismounting,, on the surface of jib length and Width, be equipped with the walking pedal usually for the ease of operator's walking.Yet because the needs of structure, the height of crane arm support often can reach two meters or higher.Under these circumstances, the operator moves very inconvenient on the jib short transverse.For this reason, weld several steel plates or steel pipe in the jib side usually, so that the operator climbs operation.But, it should be noted that the employing said method, the operator is faced when climbing steel plate or steel pipe slide into the danger of falling.Simultaneously, the jib of said structure is also attractive in appearance inadequately on the whole.
The utility model content
The purpose of this utility model is to provide the cat ladder of a kind of jib with high security, and the middle part that it can be installed in crane arm support makes the more convenient and safety of the operation of operating personal on short transverse.
To achieve these goals, a kind of jib of the present utility model is arranged at the crane arm support middle part with the cat ladder of high security along short transverse, and it comprises two vertical poles and is set in parallel in a plurality of pedals between two vertical poles.
According to the cat ladder of above-mentioned jib with high security, wherein, described pedal surface is concavo-convex anti-skid structure.
According to the cat ladder of above-mentioned jib with high security, wherein, described pedal surface scribbles anti-slip material.
According to the cat ladder of above-mentioned jib with high security, wherein, described cat ladder is made by lightweight material.
According to the cat ladder of above-mentioned jib with high security, wherein, described lightweight material is an aluminum alloy.
According to the cat ladder of above-mentioned jib with high security, wherein, the distance between adjacent two cat ladders is 225mm-255mm.
According to the cat ladder of above-mentioned jib with high security, wherein, the horizontal clearance of described pedal is greater than 80mm.
According to the cat ladder of above-mentioned jib with high security, wherein, the two ends of described cat ladder length direction are provided with assembly parts, are used for described cat ladder is fixed on described jib.
Therefore, a kind of jib of the present utility model adopts mounting structure with the cat ladder light weight of high security, is convenient to installing/dismounting; And pedal surface has been taked non-skid feature, and actv. has guaranteed the safety of cat ladder; Simultaneously, the design of pedal meets international relevant criterion, has more hommization.
Description of drawings
Fig. 1 is the running condition scheme drawing of a kind of jib of the present utility model with the high security cat ladder;
Fig. 2 is the mounting structure scheme drawing of a kind of jib of the present utility model with the high security cat ladder.
The specific embodiment
The utility model is described in more detail below in conjunction with accompanying drawing.
Jib of the present utility model is installed in the middle part of crane arm support with the high security cat ladder along short transverse, is used for the relevant operation of handled easily workman on the jib short transverse.As shown in Figure 1, walking pedal 3 all is installed, so that the operation of operator on length and Width on the length of jib 1 and the surface of Width.For the ease of the operation on the jib short transverse, 2 central parts that are installed in jib of a kind of high security cat ladder of the present utility model.As shown in Figure 2, the two ends of cat ladder 2 are equipped with assembly parts, and it can be used for cat ladder 2 is fixed on the jib 1.So, the installation when helping cat ladder 2 uses, the dismounting during withdraw from use.
Introduce the structure of jib of the present utility model below in detail with the high security cat ladder.This cat ladder comprises two vertical poles and is set in parallel in a plurality of pedals between two vertical poles.Handle the workman and on the pedal of certain altitude, carry out operation by climbing.In order to guarantee the safety of this cat ladder, pedal surface is designed to concavo-convex anti-skid structure, as by adopting the surface to realize for the material of pattern structure.In addition, also can be coated with anti-slip material, thereby reach skidproof effect in pedal surface.
In a preferred embodiment of the present utility model,, adopt lightweight material to make this cat ladder, as materials such as aluminum alloys in order further to be convenient to the dismounting of cat ladder.
In another preferred embodiment of the present utility model, in order to increase the traveling comfort of cat ladder, make it to have more hommization, with reference to the relevant international standard of cat ladder, vertical distance between adjacent two pedals is set to 225mm-255mm, and the horizontal clearance of pedal is set to the distance greater than 80mm.So, the operator meets human physiological structure's characteristics more along the climbing action of cat ladder, coordinates more.
More than specific embodiment of the utility model is described in detail, but the utility model is not restricted to specific embodiment described above.Any equivalent modifications that this jib is carried out with the cat ladder of high security and substituting also all among category of the present utility model.Therefore, not breaking away from impartial conversion and the modification of having done under the spirit and scope of the present utility model, all should be encompassed in the scope of the present utility model.
