Description

Hanging opening labor-saving channel cover plate device

Technical Field

The utility model relates to a hang laborsaving passageway apron device of mouthful belongs to water and electricity, thermal power plant and overhauls the field.

Background

In water and electricity or thermal power plant, some equipment fixing are on the platform, not install on the platform a bit, some are on 0 meter layer, some are in the intermediate level, because of equipment fixing and maintenance needs, must set up the hanging opening that differs in size on the ground on the operation layer of water and electricity and thermoelectricity, these hanging openings are decided by equipment size, so that can hang equipment into smoothly with the overhead traveling crane and hang out, but in the maintenance process, need remove the grid plate that originally covers, for safety, must install the fender around the hanging opening, prevent the personal safety accident that falls, used fender all is warning area or warning board, the warning bounding wall does not support and fixes, also very easily fall the wounded, warning area rail also very easily takes place article and drops and injures the danger of maintainer or equipment. The overhaul is finished, and when the grid plate is used for covering, the danger of falling objects is easy to occur, and the equipment below is injured by smashing. And thus both are less safe.

Disclosure of Invention

The to-be-solved technical problem of the utility model is: how to prevent to enclose fender and grid plate and take place the problem that drops.

In order to solve the technical problem, the technical scheme of the utility model a hang laborsaving passageway apron device of mouth is provided, a serial communication port, including fixing at the subaerial fixed plate of concrete, the welding has the frame on the fixed plate, and both sides all are equipped with big apron around the frame, and the below of big apron is connected with a plurality of gear counterweight arm that make big apron upset 90, and the left and right sides of frame all is equipped with the guardrail, and the guardrail passes through rotation axis and frame fixed connection.

Preferably, the gear counterweight arm is arranged at the middle position below the outer frame.

preferably, the gear counterweight arm include the counterweight iron, the counterweight iron is located one of gear lower arm and is served, the other end of gear lower arm is connected with the one end that the gear supported the upper arm through the gear, the other end that the gear supported the upper arm and big apron welding.

Preferably, the large cover plate turned up by 90 degrees is flush with the guardrail; the big cover plate and the guardrail form a tight surrounding barrier.

Preferably, the large cover plate is provided with a handle.

Preferably, at least 5 sets of gear counterweight arms are arranged below the large cover plate.

the device of the utility model can replace the original grid plate when being tiled, so that the installation and maintenance personnel can operate on the grid plate, and the guardrail is fixed on the device of the utility model, and the device of the utility model is fixed on the concrete ground, thereby avoiding the falling of the guardrail; also can with the utility model discloses a big apron and guardrail are turned up 90, form safe tight warning and enclose the fender, prevent to take place the personal safety accident that falls to and the guardrail collapses and injures the people.
