Abstract

The invention discloses a ground hole digging device for a large power cement pole. The ground hole digging device comprises an outer annular block. According to the ground hole digging device, by using an external thread structure with a rotation function, underground soil can be rotatably conveyed, and the hole digging function is achieved; meanwhile, by using a distance adjustment mechanism inthe device, the external thread structure digging a hole can be transversely adjusted, in cooperation with the external rotation function, rotation can be constantly adjusted, column diameter controlis achieved, and thus the working range is expanded; besides, the device is provided with bolt installation telescopic limiting connection mechanisms, the longitudinal movement function of componentswill not be affected, and longitudinal movement for hole digging is achieved; moreover, the device is provided with the reverse thread structure rotary transverse distance adjustment mechanism, and thus the transverse dimension of the hole can be adjusted; and furthermore, the device is provided with a coil spring elastic abutting type maximum rotation intensity control mechanism, and thus permanent phenomena caused by excessive rotation resistance to the external thread structure are prevented.

Description

technical field [0001] The invention relates to the technical field of electric power installation, in particular to a ground hole digging device for large electric cement poles. Background technique [0002] At present, when installing electric cement poles, it is necessary to dig holes on the ground, but the existing hole-digging device is inefficient, and the quality of the holes is relatively poor, and the integrity of the inner surface of the hole is poor, resulting in the ability to fix the cement poles. Difference. Contents of the invention [0003] The purpose of the present invention is to provide a ground digging device for large electric cement poles, so as to solve the problems raised in the above-mentioned background technology. [0004] In order to achieve the above object, the present invention provides the following technical solutions: a ground digging device for large-scale electric cement poles, including an external ring block, the bottom of which is e...
