The invention particularly discloses a cable trench excavating machine for integrated grounding engineering of a high-speed railway, which aims to solve the problems that time and energy are wasted and the construction efficiency is influenced since a cable trench on a roadbed in the conventional integrated grounding engineering is excavated manually or by virtue of a pneumatic pick. The cable trench excavating machine comprises a tractor head and a support which is connected with the tail part of the tractor head, wherein a stretching rod is hinged with the tractor head and the support and is arranged between the tractor head and the front part of the support; a wheel disc is arranged on the right side of the support; alloy steel drill bits are uniformly distributed and fixed on the outer cylindrical surface of the wheel disc; a protective cover which is fixed with the support is arranged on the upper part of the wheel disc; a balancing weight is arranged on the left side of the support; a directional wheel is arranged below the tail part of the support; and a power output shaft of the tractor head is in transmission connection with a central shaft of the wheel disc. The cable trench excavating machine is reasonable and reliable in structural design, and the excavation operation of the cable trench can be finished by one person independently by virtue of the cable trench excavating machine, so that a lot of manpower and material resources are saved, and the cost is reduced; and the cable trench excavating machine has the advantages of simple structure, convenience in transportation and fastness and convenience in use.
Description
technical field [0001] The invention relates to ditching equipment for high-speed railways, in particular to a cable trench excavator for high-speed railway comprehensive grounding engineering. Background technique [0002] Due to the needs of high-speed railway construction, the excavation face of the cable trench of the comprehensive grounding project is located on both sides of the road cutting or the bare shoulder foundation, with a width of about 70cm, which is 50cm lower than that of the road with a certain slope in the middle, which is not convenient for general construction machinery. Therefore, it is very difficult to excavate the cable trench on the roadbed where the working face is limited by extreme conditions, especially the excavation on the compacted filler is even more difficult. Contents of the invention [0003] The present invention provides a cable trench excavator for high-speed railway comprehensive grounding engineering in order to solve the problem ...
