Abstract

The utility model provides a ladder stand on a loading machine, comprising multilevel pedals, a left curved arm and a right curved arm, wherein the left curved arm and the right curved arm are respectively arranged at two sides of the multilevel pedals; each pedal comprises a framework and the framework is composed of a first sheet body, a second sheet body, a third sheet body and a fourth sheet body which are connected with one another; the left curved arm and the right curved arm are respectively and fixedly arranged at the outer side of the first sheet bodies and the outer side of the second sheet bodies, which is opposite to the first sheet bodies. The most part of each pedal of the ladder stand on the loading machine, provided by the utility model, is hollow, so that mud cannot be deposited on each pedal. The ladder stand on the loading machine provided by the utility model has the advantages of simplicity in structure, convenience for detaching and assembling, fewer production links and capability of greatly reducing the production cost.

Description

Cat ladder on the loader

Technical field

The utility model relates to a kind of conveying arrangement of loading or unloading, particularly relates to the cat ladder on a kind of loader.

Background technology

Be similar to the oversize vehicle of loader, mechanically cat ladder be installed all.The structure of the cat ladder on common a kind of loader is as shown in Figure 1, it comprises multistage pedal 1, be arranged at multistage pedal 1 both sides crank arm 2.Wherein pedal 1 is the rectangular box shape, and it comprises housing 3, and the housing 3 upper surfaces blunderbuss that makes progress goes out magic flower 4, as antiskid part.In the practical work, be easy to stockpile a large amount of earth, dust on the pedal 1 of this cat ladder, cause magic flower 4 (antiskid part) to be capped, can't play anti-skidding effect.

The utility model content

The technical problem that the utility model will solve provides the cat ladder on the loader that can not stockpile earth on a kind of simple in structure, pedal.

Cat ladder on the loader of the utility model; Comprise that cranking arm in multistage pedal, a left side that is arranged at said multistage pedal both sides respectively, cranks arm in the right side; Said pedal comprises framework; Said framework is formed by connecting first lamellar body, second lamellar body, the 3rd lamellar body, the 4th lamellar body, cranks arm and be fixed in the outside of first lamellar body in a said left side, cranks arm and be fixed in the outside of said second lamellar body relative with said first lamellar body in the said right side.

Preferably, the top of said the 3rd lamellar body, said the 4th lamellar body is provided with antiskid part.

Preferably, said antiskid part is first anti-slop serrations that projects upwards.

Preferably; Said pedal also comprises first support chip and second support chip; Vertical respectively said first lamellar body, said second lamellar body of connecting in the said first support chip two ends; Vertical respectively said the 3rd lamellar body, said the 4th lamellar body of connecting of said second support chip, said first support chip and said second support chip intersect in said framework internal vertical.

Preferably, the top of said first support chip is provided with and is used for the second anti-skidding anti-slop serrations.

Preferably, crank arm through the outside of bolt in said first lamellar body in a said left side, cranks arm through the outside of bolt in said second lamellar body in the said right side.

The pedal of the cat ladder on the loader of the utility model is owing to be to be formed by connecting first lamellar body, second lamellar body, the 3rd lamellar body, the 4th lamellar body, its inner most hollows, so earth can't stockpile on pedal.Cat ladder on the loader of the utility model is simple in structure, dismounting and easy to assembly, and production link is less, significantly reduces production costs.

The specific embodiment

Like Fig. 2, Fig. 3, shown in Figure 4; Cat ladder on the loader of the utility model; Comprise that multistage pedal 10, a left side that is arranged at multistage pedal 10 both sides respectively crank arm 11, the right side cranks arm 12, said pedal 10 comprises framework 20, and framework 20 is formed by connecting first lamellar body 21, second lamellar body 22, the 3rd lamellar body 23, the 4th lamellar body 24; A left side crank arm 11 be fixed in first lamellar body 21 the outside, the right side crank arm 12 be fixed in second lamellar body 22 relative with first lamellar body 21 the outside.A left side cranks arm 11, crank arm in the right side 12 plays a supportive role.Pedal 10 is that monoblock cast is shaped.

The pedal 10 of the cat ladder on the loader of the utility model is owing to be to be formed by connecting first lamellar body 21, second lamellar body 22, the 3rd lamellar body 23, the 4th lamellar body 24, so earth can't stockpile on pedal 10.

The operator climbs for ease, and in the present embodiment, the top of the 3rd lamellar body 23, the 4th lamellar body 24 is provided with antiskid part 25.

In the present embodiment, first anti-slop serrations 26 of antiskid part 25 for projecting upwards.

In order to make pedal 10 firm, durable; In the present embodiment; Pedal 10 also comprises first support chip 31 and second support chip 32; First support chip, 31 two ends are respectively vertical to connect that first lamellar body 21, second lamellar body, 22, the second support chips 32 vertically respectively connect the 3rd lamellar body 23, the 4th lamellar body 24, the first support chips 31 are crossing in framework 20 internal vertical with second support chip 32.

In the present embodiment, the top of first support chip 31 is provided with and is used for the second anti-skidding anti-slop serrations 27.

In order to dismantle with easy to assembly, in the present embodiment, a left side crank arm 11 through bolt in the outside of first lamellar body 21, the right side crank arm 12 through bolt in the outside of second lamellar body 22.A left side cranks arm 11, cranking arm in the right side, 12 both sides offer connecting hole respectively.A left side cranks arm 11, crank arm in the right side 12 is connected with two outsides of pedal 10 respectively through connect apertures.The pedal of the cat ladder on the loader of the utility model is owing to inner most hollows, so earth can't stockpile on pedal.Cat ladder on the loader of the utility model is simple in structure, dismounting and easy to assembly, and production link is less, significantly reduces production costs.

It below only is the preferred implementation of the utility model; Should be pointed out that for those skilled in the art, under the prerequisite that does not break away from the utility model principle; Can also make some improvement and retouching, these improvement and retouching also should be regarded as the protection domain of the utility model.
