Description

Driving device for folding cover plate

Technical Field

The present utility model relates to a cover plate, in particular to a driving device for a cover plate with larger size.

Background

In the project of the material hanging hole cover plate of the pumped storage hydropower station, a special-shaped hole safety labor-saving cover plate exists, the material hanging hole cover plate is designed to be a mixed cover plate in order to better ensure effective opening, the special-shaped hole edge is designed to be a single-side conventional type, and the hole opening at the other side is designed to be double-folding. However, the double-folding cover plate occupies a larger effective opening after being folded, so that the practical requirement is not met, and in order to solve the problem, the cover plate is improved in a plurality of technologies, wherein one of the technical improvements is that the folding bottom plate is punched through a dead point of a track and is perpendicular to the track as much as possible, and the effective opening is enlarged. Although the effective opening meets the requirement, when the suspended object hole cover plate is closed, the driving part cannot drive the driven part to work due to the existence of the track dead point, so that the folded cover plate cannot pass through the track dead point, and the suspended object hole cannot be closed, so that whether the folded cover plate smoothly rushes through the track dead point or not can be realized through a driving device is not reported.

Disclosure of Invention

Aiming at the situation, in order to overcome the defects of the prior art, the utility model aims to provide a driving device for a folding cover plate, which can effectively solve the problem that a hanging hole cannot be closed due to the fact that the folding cover plate cannot pass through a track dead point.

In order to achieve the above purpose, the technical scheme of the utility model is that the driving device used on the folding cover plate comprises a driving rod and a shaft, the folding cover plate comprises a first bottom plate and a second bottom plate which are connected in a folding way, a through hole is formed in the first bottom plate along the longitudinal direction, the shaft is fixedly arranged in the through hole along the short direction, a shaft sleeve is sleeved outside the shaft, the shaft sleeve is provided with an integrated driving rod and a pedal rod, an included angle of 100-120 degrees is formed between the driving rod and the pedal rod, and the pedal rod is sleeved with a detachable stressing rod.

The utility model has simple structure, attractive and elegant appearance, convenience and practicality, easy production and manufacture, wide application range and good social and economic benefits, and solves the problem of closing the bottom plate of the folding cover plate.

Fig. 3 is a state diagram of the present utility model (where a is the original state and b is the driving state).

Description of the embodiments

The following detailed description of specific embodiments of the utility model refers to the accompanying drawings and the detailed description.

The driving device for the folding cover plate comprises a driving rod and a shaft, wherein the folding cover plate comprises a first bottom plate 6 and a second bottom plate 7 which are connected in a folding way, a through hole is formed in the first bottom plate 6 along the longitudinal direction, a shaft 3 is fixedly arranged in the through hole along the short direction, a shaft sleeve 2 is sleeved outside the shaft 3, an integrated driving rod 1 and a pedal rod 4 are arranged on the shaft sleeve 2, an included angle of 100-120 degrees is formed between the driving rod 1 and the pedal rod 4, and a detachable stress application rod 5 is sleeved on the pedal rod 4.

In order to ensure better implementation effect, the stress application rod 5 is a hollow round tube made of a 1 inch galvanized pipe, and the length is 300mm.

An openable upper cover (not shown in the figure) is arranged outside the through hole, so that safety is ensured.

In the initial state, the driving rod 1 is perpendicular to the track, and in particular, in order to ensure that the driving device can be completely hidden inside the first bottom plate 6 (i.e. in the through hole) during manufacturing, the length of the foot rest rod 4 is shortened, but the length is hard to operate, so that the foot rest rod 4 is sleeved with the stress application rod 5 during use, the length is increased, the stress application rod 5 is placed in the handle groove (in the prior art) of the bottom plate 1 when not in use, and the foot rest rod 4 is taken out from the handle groove and sleeved when in use.

When the utility model is specifically used, as shown in fig. 3, in the state a in fig. 3, the folding bottom plate is in a fully folded state, when the folding bottom plate with the hanging hole is required to be closed, the stressing rod 5 is firstly taken out and sleeved on the pedal rod 4, the foot treads the stressing rod 5, at the moment, the shaft sleeve 2 drives the driving rod 1 to rotate inwards, the driving rod 1 props against the second bottom plate 7 through rotation, and a leftward (relative to fig. 3) driving force is provided for the second bottom plate 7, so that the rail wheel obtains an effective driving force, the rail wheel smoothly passes through a dead point, and the hanging hole equipment is smoothly closed.

The folding cover plate bottom plate is simple in structure, attractive and elegant in appearance, convenient and practical, easy to manufacture, free of extra area, convenient to operate, wide in application range and good in social and economic benefits, and the problem that the folding cover plate bottom plate is closed is solved.

It is noted that the above-mentioned embodiments are merely preferred embodiments of the present utility model, and the present utility model is not limited thereto, and that any person skilled in the art can make modifications or variations within the scope of the present utility model without departing from the scope of the present utility model.
