Combined type digging and drilling machine

Abstract

The invention relates to a combined type digging and drilling machine. The combined type digging and drilling machine comprises a support, slide rails, a soil discarding mechanism, a drilling rod, a power head, a drilling head, a winch and two hydraulic cylinders. The slide rail is fixedly connected on the support and comprises a horizontal rail and a vertical rail. The soil discarding mechanism is arranged on the slide rail and driven to run on the slide rail via the hydraulic cylinder. The drilling rod is connected on the slide rail and penetrates through the power head. Two ends of the power head are slidingly connected to the vertical rail. The drilling head is detachably connected at the lower end of the drilling rod. The winch is arranged on the support and connected to the top end of the drilling rod via a steel cable. One ends of the two hydraulic cylinders are respectively connected with a longitudinal beam of a slide frame, and the other ends are connected on the support or on the slide rail. The combined type digging and drilling machine is convenient to move on the scene, has no special requirement on terrain and is applicable to plains, hills and ordinary mountain areas.

Description

technical field [0001] The invention relates to an excavating machine in the field of electric power engineering construction, in particular to a combined excavating drilling rig. Background technique [0002] The excavation foundation is a commonly used foundation type in transmission line engineering. It has significant advantages in environmental protection, reducing the amount of excavation (excavation), concrete maintenance, reducing backfill operations, facilitating construction, shortening the construction period, and making full use of undisturbed soil conditions. It is in line with the energy-saving concept of power grid construction. However, in the specific application process, the excavation of foundation pits mainly adopts manual operation, which has low construction efficiency and potential safety hazards. In the case of slightly poor soil quality, there are safety risks in the application, which affects the popularization and use of excavation foundations. Th...

Problems solved by technology

[0003] In this case, the subject of researching excavation foundation construction technology and equipment was proposed. Although there are self-propelled crawler excavation rigs in the prior art, this type of excavation rig is used on larger excavation foundations. The technology and economy are relatively high. If it is extended to the construction of 500kV or below voltage level lines, it will also expose the contradictions of this type of drilling rig (which is crawler self-propelled) with heavy weight, difficult site transportation, and large temporary land occupation.

Especially in areas where large equipment cannot pass through or is far away from traffic roads, farmland, woodland and other areas without access roads, the existing excavation drilling rigs cannot be driven into the construction, and the self-propelled drilling rigs need to destroy the crops in the farmland or trees in woodland
