Embodiment Construction

[0016] The specific implementation will be described below in conjunction with the accompanying drawings.

[0017] Such as figure 1 figure 2 As shown, the telescopic foot-operated suspended ladder includes a mounting device, a suspended ladder and a return spring. Such as figure 1 As shown, the mounting device is composed of a mounting plate 1 and a guide device, wherein the mounting plate 1 is provided with screw holes 2 for fixed connection and installation with the vehicle frame 18 using bolts. The guiding device is a vertical left sleeve 3 and a right sleeve 4. The left sleeve 3 and the right sleeve 4 are respectively arranged on the left and right sides of the mounting plate 1, and the left sleeve 3 and the right sleeve 4 are parallel to each other. The suspended ladder includes a left column 5 and a right column 6, and between the left column 5 and the right column 6, several levels of pedals arranged at intervals up and down are fixed, and the pedals are located at ...

Abstract

The invention relates to a hanging ladder and provides a telescopic pedal type hanging ladder aiming at the defect that the conventional hanging ladder is easily collided with a material pile or raised ground so as to be damaged. The telescopic pedal type hanging ladder comprises a hanging ladder, wherein the hanging ladder comprises a left upright post and a right upright post positioned on two sides, a plurality of stages of pedals which are vertically arranged at intervals and are fixedly arranged between the left upright post and the right upright post, a return spring and a mounting device used for mounting the pedal type hanging ladder, wherein the mounting device comprises a guide device for guiding in the vertical direction; the hanging ladder comprises a sliding device which is arranged on the guide device in a sliding mode and drives the left upright post and the right upright post to slide up and down in the vertical direction; and the return spring provides an upward elastic force for the sliding device, so that the hanging ladder slides upwards without an external force. When the telescopic pedal type hanging ladder is not used, the hanging ladder can be lifted upwards, the height between the bottommost pedal and the ground is increased, and the hanging ladder is prevented from being easily collided with a material pile or raised ground so as not to be damaged.

Description

technical field [0001] The invention relates to a foot-operated hanging ladder, in particular to a telescopic foot-operated hanging ladder. Background technique [0002] Construction machinery such as loaders are large-scale equipment, and the maintenance platform at the rear is relatively high. Based on safety requirements, a foot-operated hanging ladder needs to be installed on the side of the maintenance platform, and the maintenance platform can be entered up and down through the foot-operated hanging ladder. Or enter the mechanical operation area through the hanging ladder. Existing foot-operated suspended ladders are usually formed by steel plate welding or bolt fastening connection, and are rigidly installed on the vehicle frame or on the maintenance platform. Based on safety considerations, the distance between the lowest step of the foot-operated hanging ladder and the ground is usually not large. The lower end of the ladder is easy to collide with the raised grou...
