Dregs tipping device

Abstract

The invention discloses a residual soil tipping device for a gantry crane used in construction of underground. The residual soil tipping device mainly comprises a tipping hook, a sliding seat, a bearing seat, a screw rod, a guide sleeve, a tooth-type coupler, a speed reducer, a motor, a fixed guide rail, a moving guide rail, a connecting rod, position switches and a pin shaft and is mainly characterized in that: a discharge mechanism is installed on a trolley of the crane to realize output of residual soil at arbitrary position; the motor and the speed reducer are used for directly driving the sliding seat to move on the fixed guide rail through the screw rod, so automatic hanging and discharge of the tipping hook is realized; and during working of the residual soil tipping device, a determined position for hanging and discharging of the tipping hook is controlled by the position switches installed at the two ends of the fixed guide rail. The residual soil tipping device adopts pure mechanical transmission, is simple in structure, low in manufacturing cost, low in fault rate, convenient and easy for maintenance, safety, reliable, and high in working efficiency.

Description

technical field [0001] The invention belongs to hoisting machinery for subway construction, and relates to a purely mechanically driven muck dumping device. Background technique [0002] At present, gantry cranes or crawler cranes are mainly used for muck output in subway construction to cooperate with special muck buckets to transport muck excavated from the ground to the ground. Because the crawler crane is used to output the muck, the volume of the muck bucket that can be used is small, the operation efficiency is low, the energy consumption is large, and the cost is high. At present, most of the gantry cranes are used to output the muck. The main reason is that the muck bucket used by the gantry crane has a large volume and high operating efficiency. However, there are basically two ways of muck output at present: one is the hook and manual cooperation. To realize the dumping, the other is to use a special dumping device or a hydraulic dumping device at a fixed position...

AI Technical Summary

Problems solved by technology

The disadvantages of these two methods are: when using the hook to dump the bucket, it is necessary to manually hang and unload the dump hook. This method is not only inefficient but also has certain safety hazards; On a certain ground beam of a gantry crane, the muck bucket must be transported to the end of the main girder of the gantry crane by a trolley before dumping can be performed. If it is necessary to output muck at other positions, it cannot be realized. This method has certain limitations during use. Limitations; using a hydraulic tipping device for tipping requires a special hydraulic system and high cost
