Trenching device for urban road construction

Abstract

The invention discloses a trenching device for urban road construction and relates to the technical field of resource and environmental technologies. The trenching device for urban road construction comprises a supporting slide rod; fixed supporting rods are symmetrically and fixedly connected to the two ends of the bottom of the supporting slide rod; fixed bases are fixedly connected to the bottoms of the fixed supporting rods; a first slide rod is arranged on the surface of the supporting slide rod in a sleeving mode; the surface of the supporting slide rod and the first slide block are in sliding connection; a first telescopic rod is fixedly connected to the bottom of the first slide block; a first outer frame is fixedly connected to the end, away from the first slide block, of the first telescopic rod; a first motor is fixedly connected to the top of an inner cavity of the first outer frame through a fixing block; and a first rotating shaft is rotationally connected to the rotatingend of the first motor. The trenching device for urban road construction achieves the purpose of reducing the trenching cost, the whole device is simple in structure and low in manufacturing cost, and trenches are uniform in size and specification.

Description

technical field [0001] The invention relates to the technical field of resources and environment, in particular to a digging device for urban road construction. Background technique [0002] Road engineering refers to the whole process of planning, design, construction, maintenance and management of roads and the engineering entities involved. Like any other category of civil engineering, roads have obvious technical, economic and management characteristics. Road construction often uses machinery for digging holes, such as erecting street lights, utility poles and billboards, etc., and greening also uses As far as the device for digging pits, the existing urban construction belts generally need special digging machines for digging pits, and the existing digging machines are generally large in size, occupy a large space when used, are inconvenient to use, and are now Some digging machines have high production costs, which is not conducive to reducing the overall digging cost...

AI Technical Summary

Problems solved by technology

[0004] Aiming at the deficiencies of the prior art, the present invention provides a digging device for urban road construction, which solves the problem that the existing digging machines are generally large in size, need to occupy a large space when used, are inconvenient to use, and the existing digging machines The production cost of the pit machine is relatively high, which is not conducive to reducing the overall cost of digging the pit. At the same time, the shape of the pit of the existing pit digging machine is irregular, especially when digging a circular pit, the radius of the pit cannot be adjusted, and the size of the pit The problem of different specifications
