Supporting-pulling-extending soil-grabbing and hole-drilling apparatus

Abstract

The invention relates to the piling working equipment field, discloses a supporting-pulling-extending soil-grabbing and hole-drilling apparatus. The working principle of the apparatus is as follows: a well wall is supported; a steel wire rope is pulled up, and the apparatus extends downwardly and presses down. The apparatus comprises a drill head module and a winding engine. The winding engine is connected with the drill head by a steel wire rope; and the steel wire rope transmits power. The drill head module consists of a drill head assembly, a support assembly, a push-down assembly, and an unloading hanging assembly. Using the apparatus provided by the invention, high power can be transmitted and the piling effect is obvious. Moreover, the apparatus having a simple structure can be transported easily; and the production cost is low. The apparatus can be installed at a small transport vehicle or at a rotating plate and can work as an excavator to unload and transport soil and stones. The apparatus is suitable for various piling environments.

Description

technical field [0001] The invention relates to piling and drilling equipment in the fields of highways, bridges and construction machinery, in particular to a drilling device for power transmission by steel wire ropes. Background technique [0002] Piling operations are commonly used in construction of various roads and bridges, houses, dams and embankments. It has increasingly become an indispensable link in the construction of buildings, highways and bridges. [0003] The drilling and piling equipment in the prior art mainly includes a rotary excavator for power transmission by a drill rod, a punching and grabbing drill for power transmission by a diesel hammer and a steel wire rope, and Luoyang shovel piling and the like. The rotary excavator that transmits power through the drill pipe drills and drives piles through the auger bit. This machine has good drilling and piling effect and high efficiency. However, the drilling depth is limited by the length of the rotating...

AI Technical Summary

Problems solved by technology

The equipment is too high, easy to fall and cause safety accidents

The advantage of punching and grabbing drills and Luoyang shovels is that they use light wire ropes to transmit power. To increase the drilling depth, you only need to increase the length of the wire ropes, which hardly increases the equipment. Due to the weight of the drill bit, it is necessary to lift the heavy drill bit and use the drill bit to drive piles. The heavier the drill bit, the higher the free fall height, the better the piling effect. Therefore, a tripod has to be used to support the equipment, so it is not suitable for operations in small spaces, and the impact vibration may affect the piling effect. safety to existing buildings
