Multi-section combined earthwork vertical lifting device

Abstract

The invention relates to a multi-section combined earthwork vertical lifting device. A bottom section of a structure framework is mounted on a foundation pit excavating surface; a standard section of the structure framework is mounted on the bottom section; a top section of the structure framework is mounted on the standard section; a supporting wheel is mounted on the structure framework; guide wheels are further mounted on the bottom section and the top section; track chains are mounted in the grooves of the supporting wheel and the guiding wheels; a hopper is mounted on a hopper shaft through a hinge; the hopper shaft is mounted between two track chains; a plurality of driving devices are mounted on a beam plate or a trestle of a top layer structure and beam plates of all structures in the lower layer, and are used for driving the track chain to drive the hopper to be lifted; a ratchet device is mounted at the bottom of the hopper; opening and closing control is performed through the ratchet device, so that unloading is accomplished. The device solves the problems that rotation operation is required when a long arm excavator or a caterpillar grab bucket shovel beside a soil outlet performs vertical lifting soil loading in reverse building method engineering, and large operating space is required, greatly improves the operating efficiency of earthwork soil discharging in the reverse building method engineering, and meanwhile reduces the space occupied by oil discharging operation.

Description

technical field [0001] The invention relates to a vertical continuous excavation transportation device for deep foundation pit construction, in particular to a vertical earth lifting device. Background technique [0002] In deep foundation pit top-down construction, the key to restricting the construction period is the speed of earthwork transportation. Most of the top-down projects use long-arm excavators, crawler grab shovels or gantry cranes to excavate directly from the excavation hole. Since the long-arm excavator or crawler grab shovel near the excavation hole needs to be rotated when vertically lifting and loading soil, it needs a large operating space, and large machinery and vehicles need to go up the floor. These excavation methods are mainly suitable for the excavation of basements with podiums, or semi-inverted projects. When the above-ground part occupies almost the same area as the underground part, and the construction operation surface is tense, the commonl...
