A multi-purpose mechanical cleaning door crane for hydropower stations

Abstract

The invention provides a multipurpose mechanical dirt removing portal crane for a hydropower station. The multipurpose mechanical dirt removing portal crane integrates starting, stopping, swinging, dirt removing and dirt collecting. Tracks are fixed to a support. A left electric block and a right electric block are installed on a left moving mechanism and a right moving mechanism and are oppositely arranged in the longitudinal direction. The two ends of a connecting beam are connected with the left electric block and the right electric block. Coiling block mechanisms of the left electric block and the right electric block are connected together through a synchronous shaft connecting device. Lateral wheels are rotationally arranged on a scraper bucket frame. The wheel faces of the lateral wheels stretch out of the side edges of the scraper bucket frame, and rotation shafts of the lateral wheels are perpendicular to the scraper bucket frame. Outer guiding wheels are rotationally arranged on the outer side face of the scraper bucket frame. The wheel faces of the outer guiding wheels stretch out of the side edges of the scraper bucket frame, and rotation shafts of the outer guiding wheels are parallel to the scraper bucket frame. Inner guiding wheels are rotationally arranged on the inner side face of the scraper bucket frame, the wheel faces of the inner guiding wheels stretch out of the inner side face of the scraper bucket frame, and rotation shafts of the inner guiding wheels are parallel to the scraper bucket frame. An overturning plate is arranged in an overturning manner, an overturning plate driving mechanism is connected with the overturning plate, and a dirt collecting box is located below the overturning plate.

Description

technical field [0001] The invention relates to a multipurpose mechanical cleaning door machine for hydropower stations. Background technique [0002] The sewage cleaning door machine is used to clean up the dirt in the hydropower station, such as the Chinese patent application number 201220744855.1. The cleaning door machine of the prior art has the following defects: [0003] 1. The traditional mechanical decontamination door operator generally only has one set of decontamination device, that is, the door operator has only one decontamination function. However, due to the arrangement relationship between gates and trash racks in general hydropower stations, a set of lifting gate devices and a set of cleaning devices are often required in limited space at the same time, but the actual situation is often the spatial location of these two independent devices The size is not enough. If the size of the dam surface is increased to meet the arrangement of these two sets of devi...

AI Technical Summary

Problems solved by technology

[0003] 1. The traditional mechanical decontamination door operator generally only has one set of decontamination device, that is, the door operator has only one decontamination function

However, due to the arrangement relationship between gates and trash racks in general hydropower stations, a set of lifting gate devices and a set of cleaning devices are often required in a limited space, but the actual situation is often the spatial location of the two sets of independent devices. The size is not enough. If the size of the dam surface is increased to meet the arrangement of the two sets of devices, the construction cost and construction period of the power station will be greatly increased

[0004] 2. The traditional mechanical cleaning rake bucket has only 4 guide wheels, so there must be guide grooves on both sides of the dirt block to clean the dirt in the water

In reality, due to the limitation of the structural size of the dam surface and other reasons in many hydropower stations, there are no guide grooves on both sides of the pollution control, which greatly restricts the use of this type of mechanical cleaning bucket

Because there must be a guide groove, it not only increases the workload and construction difficulty of civil engineering, but also increases the construction cost
