Problems solved by technology

When laying underground cables, corresponding cable trenches need to be excavated. At present, excavators are often used to complete the excavation of cable trenches. When laying a single cable, due to the relatively large size of the excavator bucket, the width of the excavated cable trench Larger, which increases the amount of construction work in the later stage, resulting in an increase in the cost of cable laying

Embodiment

[0029] Embodiment: The present invention is an excavation device for directly buried cable trenches, including a first support frame, and the bottom of the first support frame is symmetrically provided with anchor bolts, which can secure the first support frame It is fixed on the ground, which can ensure the stability of the present invention in use. The lower part of the first support frame is welded with a support beam, and several nuts are welded on the support beam, and a screw rod is arranged inside the nut, a crank handle is installed on the top of the screw rod, and a universal wheel is installed on the bottom of the screw rod. When setting up the first support frame, turn the handle to move the universal wheel down, which can facilitate the movement of the first support frame and the erection of the first support frame. After the erection is completed, reverse the handle to move the universal wheel Moving up can facilitate the fixing of the first support frame and faci...

Abstract

The invention discloses an excavation device of a direct burial cable trench and belongs to the electric power planning technical field. The excavation device comprises a first supporting frame; the bottom of the first supporting frame is provided with foundation bolts; the top of the first supporting frame is provided with a guide rail; the guide rail is provided with a supporting seat; the supporting seat is in sliding connection with the guide rail; the first supporting frame is provided with a traction mechanism for driving the supporting seat to move; a supporting plate is arranged below the supporting seat; the supporting plate is provided with guide columns; the supporting seat is provided with a guide sleeve which is adaptive to the guide columns; the supporting seat is provided with a supporting plate lifting mechanism; the bottom of the supporting plate is provided with a supporting cylinder; the bottom of the supporting cylinder is provided with a disc milling cutter; and one end of the supporting plate is provided with a cleaning device. With the excavation device of the invention adopted, a cable trench of a corresponding width can be excavated in a road, and the engineering amount of later-stage construction can be decreased, and cable laying cost can be reduced.

Description

technical field [0001] The invention relates to the technical field of electric power planning, in particular to an excavation device for directly buried cable trenches. Background technique [0002] In urban power planning, in order to avoid potential safety hazards caused by too many overhead cables, when laying cross-over cables, the transmission lines are often laid underground, which can effectively improve the safety and reliability of the power distribution system. When laying underground cables, corresponding cable trenches need to be excavated. At present, excavators are often used to complete the excavation of cable trenches. When laying a single cable, due to the relatively large size of the excavator bucket, the width of the excavated cable trench Larger, which increases the amount of construction work in the later stage, resulting in an increase in the cost of cable laying. Contents of the invention [0003] The purpose of the present invention is to provide ...
