Hydraulic system for manual emergency lifting of whole box hopper

Abstract

The invention discloses a hydraulic system for manual emergency lifting of a whole box hopper. The system comprises a motor, a hydraulic pump, a three-position four-way O-shaped electromagnetic reversing valve, a first one-way valve, a second one-way valve, a two-position two-way electromagnetic reversing valve, a hopper oil cylinder, a high-pressure ball valve, a manual pump and an oil tank. Thehydraulic system has the following characteristics that 1, under the normal working condition, when a power source suddenly breaks down, the hopper can be guaranteed to be safe and not to decline sharply, and the personal safety is not endangered; 2, when a power system fails, the hopper can undergo manual emergency lifting conveniently, so that the fault can be eliminated in time, and the garbageoperation efficiency is ensured; 3, a hook arm vehicle can be guaranteed to conveniently and timely perform hoisting and transporting when the fault is large and a whole box needs to be transported to a maintenance factory for overhaul; 4, the hopper can rapidly and safely undergo manual emergency lifting, and the safety and efficiency of maintenance are ensured; and 5, the safety of life and property when a rubber pipe is burst is guaranteed.

Description

technical field [0001] The invention relates to the field of hydraulic systems, in particular to a hydraulic system with manual emergency lifting of an integral box hopper. Background technique [0002] At present, the integrated garbage compression bins of the domestic garbage compression category do not have a manual emergency lifting system for the hopper. This working mode: 1. Since the position and time of failure of the power system cannot be predicted in advance, the probability of failure of the power system of the hopper at any point of its trajectory is the same. 2. The power bin equipped with a power system is often arranged at a certain part of the movement path of the hopper swing arm (considering the volume of the storage bin and compression bin and the convenience of installation and maintenance of the power system, the power bin is generally not arranged at the position where the hopper is raised to its position ), so when the power system fails, the hopper ...

AI Technical Summary

Problems solved by technology

This working mode: 1. Since the location and time of the failure of the power system cannot be predicted in advance, at the same time, the probability of failure of the power system of the hopper at any point of its trajectory is the same

2. The power bin equipped with a power system is often arranged at a certain part of the movement path of the hopper swing arm (considering the volume of the storage bin and compression bin and the convenience of installation and maintenance of the power system, the power bin is generally not arranged at the position where the hopper is raised to its position ), so when the power system fails, the swing arm of the hopper may block the power bin door, making it impossible to pull out the power system for troubleshooting and repair

3. If the oil pipe of the hopper oil cylinder is removed and the position of the hopper is changed by external force or gravity, due to the heavy weight of the hopper, it may cause regeneration accidents that endanger the personal safety of maintenance personnel.

4. When the fault problem is relatively large and cannot be eliminated on site and needs to be taken to the maintenance factory for troubleshooting, if the hopper is not in the position of rising, it will block the lifting ring of the overall box, so that the hook arm truck cannot be hooked to the lifting ring for transfer
