Small electric excavator with cable clamping device

Abstract

The invention discloses a small electric excavator, and belongs to the field of engineering machinery. The small electric excavator comprises an excavator body, wherein a mounting frame is arranged onthe excavator body, a driving shaft is arranged in the excavator body, a driving bevel gear is fixedly connected with the driving shaft, a transmission rod is rotatably connected with the top of theexcavator body, and a first transmission bevel gear is fixedly connected with the bottom end of the transmission rod. According to the small electric excavator, a cable can be freely folded and unfolded while the cable is clamped and fixed by a clamping device, so that the cable is pulled and hanged and rubbed on the ground; the cable can be wound through a winding drum, the cable can be paid offat the front of the excavator, the cable is wound when the excavator is backing up, it is ensured that the cable at the tail of the excavator is always kept at a certain length, the cable is preventedfrom being hung on the ground, friction between the cable and the ground is avoided, and the integrity of the surface of the cable is ensured; and the cable can be kept in a tensioned state all the time through a tensioning device, and the cable is not dragged on the ground.

Description

technical field [0001] The invention relates to the field of engineering machinery, in particular to a small electric excavator with a cable clamping device. Background technique [0002] An excavator is an earth-moving machine that uses a bucket to dig materials higher or lower than the bearing surface, and loads them into transport vehicles or unloads them to the stockyard. The materials excavated by the excavator are mainly soil, coal, sediment and pre-loosened behind soil and rock. Judging from the development of construction machinery in recent years, the development of excavators is relatively fast. Excavators have become one of the most important construction machinery in engineering construction. Small electric excavators are powered by cables and are small in size. kind of excavator. [0003] Because small cable excavators use power supply cables for power supply, they will drag the cables to move together when the excavators move. Most of the existing electric ex...

AI Technical Summary

Problems solved by technology

[0003] Because small cable excavators use power supply cables for power supply, they will drag the cables to move together when the excavators move. Most of the existing electric excavators do not protect the cables, causing the cables to be dragged directly on the ground. Some small electric excavators do not have a cable clamping device, which causes the cable to drag on the ground, and most of the existing small electric excavators cannot tension the cable, causing the cable to relax during continuous retraction, which will still cause cable dragging on ground
