Embodiment 1

[0018] The present invention is a ladder structure of a pneumatic folding loader, such as Figure 1-Figure 4 As shown, it consists of a cylinder assembly 1, a push-pull rod system 2, a ladder frame 3, a rotating pedal 4, a mounting seat 5, a rotating support 6, a ladder rotating shaft 7, and a pedal rotating shaft 8.

[0019] The air source of the cylinder assembly 1 is taken from the output branch of the loader air reservoir, and the driver controls the operation of the cylinder assembly 1 through the built-in control button in the cab.

[0020] There are 3 groups of rotary pedals 4. The rotary pedals 4 are assembled with the ladder frame 3 through the pedal rotating shaft 8 respectively. After assembly, the rotary pedals 4 can rotate freely, and under the action of the cylinder assembly 1, they can be rotated to open or fold. The rotary pedal 4 is provided with a first limiting surface for controlling the opening and folding angles.

[0021] A total of 6 groups of rotating ...

Embodiment 2

[0028] In this embodiment, a set of rotating pedals 4 is mounted on the ladder frame 3 .

[0029] Others are the same as in Example 1.

Abstract

The invention discloses a pneumatic folding type loading machine climbing ladder structure which is characterized by comprising a climbing ladder frame, wherein at least one group of rotating pedals capable of being opened or folded through rotation under the effect of an air cylinder assembly is arranged on the climbing ladder frame; a push and pull rod system is fixed at one side of the climbingladder frame, and is fixedly connected with a piston rod connecting seat of the air cylinder assembly; the air cylinder assembly is fixed on an oil tank body arranged at the two sides of a loading machine; an air source of the air cylinder assembly is connected with an air storage tube output branch of the loading machine; two rotating support seats are respectively arranged at the two ends of each group of rotating pedals; each group of rotating pedals and the corresponding rotating support seat are connected through a climbing ladder rotating shaft; each rotating support seat is fixed ontoone installing seat; and the installing seats are all fixed on the oil tank body. The pneumatic folding type loading machine climbing ladder structure has the advantages that the operation requirements of the machine in a narrow space can be met; the damage to personnel, object facilities and the machine per se can be avoided; and the practicability of the machine is improved. The pneumatic folding type loading machine climbing ladder structure has the advantages that the control is convenient; the unfolding and the folding are convenient and fast; and safety and labor saving are realized.

Description

technical field [0001] The invention relates to a ladder structure for a pneumatic folding loader, which belongs to the technical field of engineering machinery. Background technique [0002] The floor height of the medium-sized loader cab is more than 1.5 meters from the ground, and the floor height of the large-scale loader cab is more than 2 meters. Therefore, ladders are installed on the left and right sides of each type of loader to realize the function of the driver climbing up and down. [0003] The conventional loader ladder structure is welded with profiles and plates and assembled on the fuel tanks on both sides of the loader. The ladders on both sides will obviously increase the width of the whole machine, which restricts the space of the work site during the mechanical operation and increases Driving is difficult; even so, it often causes injuries to on-site personnel, objects and facilities. At the same time, the ladder on the machine is often impacted and defor...
