Description

Automatic lifting cover plate device for object hanging opening

Technical Field

The utility model relates to an automatic lifting cover plate device for a lifting opening, and belongs to the technical field of hydroelectric and thermal power plant maintenance equipment.

Background

In water and electricity or thermal power plant, some equipment fixing are not all at the platform, some are on 0 meter layer, some are in the intermediate level, because of equipment fixing and maintenance needs, must set up the hanging mouth that differs in size on the ground on the operation layer of water and electricity and thermal power, these hanging mouths are decided by the equipment size, so that can hang equipment into smoothly with the overhead traveling crane and hang out, but at the maintenance in-process, need remove the net board that originally covers, must install the fender around the hanging mouth for safety, prevent to take place 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 down and hinder the people, it also very easily takes the rail to take place article to drop and injures the danger that 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 technical problem to be solved by the utility model is as follows: how to improve the safety of the ground lifting opening of the hydroelectric and thermal power operation layer.

In order to solve the technical problem, the utility model provides an automatic lifting cover plate device for a lifting port, which is characterized by comprising an outer frame, wherein the outer frame is fixedly connected with a fixed plate, a plurality of guardrail plates are connected to the periphery of the outer frame, the plurality of guardrail plates form a cylinder structure in a surrounding mode, the outer frame is rotatably connected with each guardrail plate through a rotating shaft, a connecting block is fixed on each guardrail plate, a lifter for driving the guardrail plates to turn is further fixed on the outer frame, and the telescopic end of the lifter is rotatably connected with the connecting block.

Preferably, the fixing plate is arranged at the outer side of the outer frame.

Preferably, the fixing plate is fixed on the concrete ground.

Preferably, the fixing plate is fixed on the concrete ground through expansion bolts.

Preferably, the lifter is a worm gear screw lifter, and the telescopic end of the worm gear screw lifter is rotatably connected with the connecting block through a shaft; when the telescopic end of the worm screw rod lifter extends, the guardrail plate overturns towards the outer side of the outer frame.

Preferably, the telescopic end of the worm gear screw rod lifter comprises a screw rod, one end of the screw rod is fixed on the worm gear screw rod lifter body, the other end of the screw rod is arranged in the screw rod seat and can rotate in the screw rod seat, and the screw rod seat is rotatably connected with the connecting block through a shaft.

Preferably, the bottom of the outer frame is paved with a cover plate which is flush with the ground.

The device is an automatic lifting cover plate device for a lifting port, which is upgraded and transformed on the existing structure of a labor-saving channel cover plate device for the lifting port. The device can replace the original grid plate and can also form a safe and tight warning enclosure. Install a set of electric lift device additional on original basis, can replace artifical opening and closing the apron completely.

Detailed Description

In order to make the utility model more comprehensible, preferred embodiments are described in detail below with reference to the accompanying drawings. The utility model provides an automatic lifting cover plate device for a hanging opening, wherein a labor-saving channel cover plate device which can be embedded into the hanging opening is designed according to the size of the original hanging opening, a cover plate 9 is flatly laid and is level to the ground, and the device can walk on the device. As shown in fig. 1-4, the device of the present invention includes an outer frame 1, wherein the outer frame 1 is welded to a fixing plate 2, and the fixing plate 2 is disposed outside the outer frame 1. The fixing plate 2 is fixed on the concrete ground through an expansion bolt, the outer frame 1 is rotatably connected with the first guardrail plate 4 through the rotating shaft 3, the first guardrail plate 4 is fixedly provided with the connecting block 10, the telescopic end of the turbine screw rod lifter 5 is rotatably connected with the connecting block 10 through the shaft, and the first guardrail plate 4 is driven to turn up by 90 degrees as shown in fig. 2. As shown in fig. 4, the telescopic end of the worm gear screw lifter 5 includes a screw rod, one end of the screw rod is fixed on the worm gear screw lifter body, the other end of the screw rod is arranged in a screw rod seat and can rotate in the screw rod seat, and the screw rod seat is rotatably connected with the connecting block 10 through a shaft. When the telescopic end of the worm screw rod lifter 5 extends, the guardrail plate turns towards the outer side of the outer frame 1.

In the same way, the second guardrail plate 6, the third guardrail plate 7 and the fourth guardrail plate 8 are turned up by 90 degrees to form a tight surrounding barrier, and the safety and the reliability are realized.
