Description

Adjustable excavator pedal

Technical Field

The application relates to the technical field of construction equipment, in particular to a regulating type excavator pedal.

Background

An excavator is an earth moving machine that excavates material above or below a bearing surface with a bucket and loads it into a transport vehicle or unloads it to a dump yard. In recent years, an excavator has been developed rapidly and has become one of the most important construction machines in construction. Under the general condition, the height of an excavator cab from the ground is higher, and a pedal plate needs to be installed on a longitudinal beam of an excavator chassis to facilitate workers to get on and off the excavator.

Related Chinese patent with reference to publication No. CN202482918U discloses an improved structure of a pedal of an excavator, which comprises a pedal and a mounting plate, wherein the mounting plate is fixedly connected with the excavator, and the pedal is hinged with the mounting plate through a pin shaft. When the staff need get into the excavator cab, step on the running-board and get into the excavator cab, when need not use the running-board, can cover the running-board with the articulated shaft rotation of mounting panel, pack up the running-board, can receive and release the running-board as required, reduced the running-board by the thing that falls down the possibility of bending deformation.

The above related technical solutions have the following drawbacks: because the excavator can dispose the track of different width usually, change according to the requirement of operating mode, when the width of track increases, the length that the track was stretched out to the running-board shortens for the staff is difficult for trampling the running-board when excavator from top to bottom, can appear shank and the possibility that the track board edge bumps, and the security is relatively poor when making the staff excavator from top to bottom.

SUMMERY OF THE UTILITY MODEL

In order to improve the security of the excavator about the staff, this application provides a regulation formula excavator running-board.

The application provides a regulation formula excavator running-board adopts following technical scheme:

the utility model provides an adjust formula excavator running-board, includes main running-board, and one side of main running-board links to each other with the excavator longeron, one side that the excavator longeron was kept away from to main running-board is provided with vice running-board, and vice running-board slides with main running-board and is connected, and the slip direction of vice running-board is for being close to or keeping away from excavator longeron direction.

Through adopting above-mentioned technical scheme, link to each other main footboard and excavator longeron, when changing the great track of width, because be connected for sliding between vice footboard and the main footboard, consequently can slide vice footboard along the direction of keeping away from the excavator longeron for the length that the excavator footboard stretches out the track increases, thereby it is more convenient to make the staff trample the footboard, has reduced the possibility that staff's shank and grip-pad edge bump, has improved the security of excavator about the staff.
