Description

Falling object prevention baffle plate for vertical shaft

Technical Field

The utility model belongs to the technical field of mine safety protection, and particularly relates to a vertical shaft falling object prevention baffle.

Background

In the shaft mining work, a large-scale hoisting machine with stronger hoisting capacity is adopted, and a power machine drags the flexible steel wire rope, the cage and the transported goods to move up and down to complete the transportation process; for satisfying the cage and passing through the well head smoothly, it is great to erect the well head, and in the course of the work, the cage is in the running state most of the time, and when the cage did not stop at the well head, the well head was in open state, and objects such as instrument, stone, rubbish fall into the well head easily, influence equipment operation, threaten workman life safety production.

Disclosure of Invention

In order to overcome the problems that in the background technology, the cage is in an operation state most of the time, when the cage does not stay at a well mouth, the well mouth is in an open state, tools, stones, garbage and other objects are easy to fall into the well mouth, equipment operation is affected, and life safety of workers is threatened, the utility model provides the vertical shaft falling object prevention baffle; the cage can be automatically opened when arriving, and can be automatically closed after going into the well, manual or electric control equipment monitoring is not needed, time and labor are saved, and the safety and the reliability are realized; can effectively prevent objects from falling into a wellhead and ensure the safety of equipment and workers.

In order to realize the purpose, the utility model is realized by the following technical scheme: the utility model provides a thing baffle is prevented falling by shaft mainly includes shaft, cage, hoisting wire rope, promotion piece, apron, the cage pass through hoisting wire rope hoist and mount in the shaft, on the hoisting wire rope at cage top, the apron lid was on the shaft well head, the apron middle part was equipped with the through-hole that can be supported by the promotion piece, hoisting wire rope passed after the through-hole walk around the head sheave and be connected to on the lifting machine cylinder.

The lifting block is integrally conical and is formed by welding steel bars; the through hole is fixedly provided with a conical frame matched with the lifting block, and the conical frame is formed by welding steel bars.

The cover plate comprises a keel frame and an iron sheet plate, and the iron sheet plate is welded on the keel frame.

The cover plate comprises a keel frame and a protective net, and the protective net is welded on the keel frame.

The utility model has the beneficial effects that:

the automatic opening device can be automatically opened when the cage arrives, and can be automatically closed after the cage goes into a well, so that manual or electric control equipment is not needed for monitoring, time and labor are saved, and the automatic opening device is safe and reliable; can effectively prevent objects from falling into the wellhead and ensure the safety of equipment and workers.

Detailed Description

In order to make the objects, technical solutions and advantages of the present invention more apparent, preferred embodiments of the present invention will be described in detail below with reference to the accompanying drawings to facilitate understanding of the skilled person.

The utility model discloses a vertical shaft falling object preventing baffle which mainly comprises a vertical shaft 1, a cage 2, a lifting steel wire rope 3, a lifting block 4 and a cover plate 5, wherein the cage 2 is hoisted in the vertical shaft 1 through the lifting steel wire rope 3, the lifting block 4 is fixedly arranged on the lifting steel wire rope 3 at the top of the cage 2, the cover plate 5 covers a well mouth of the vertical shaft 1, the middle part of the cover plate 5 is provided with a through hole 6 which can be supported by the lifting block 4, the lifting steel wire rope 3 passes through the through hole 6, bypasses a head sheave 7 and is connected to a lifting roller, the lifting block 4 firstly reaches the well mouth before the cage 2 is lifted to the well mouth, the lifting block 4 is supported by the through hole 6 in the middle part of the cover plate 5, and the cover plate 5 is lifted to the state shown in figure 1; when the cage 2 is lowered, the cover plate 5 is separated from the support of the lifting block 4 after the cover plate 5 contacts the well mouth, and the cover plate 5 covers the well mouth; the automatic opening device can be automatically opened when the cage arrives, and can be automatically closed after the cage goes into a well, so that manual or electric control equipment is not needed for monitoring, time and labor are saved, and the automatic opening device is safe and reliable; can effectively prevent objects from falling into a wellhead and ensure the safety of equipment and workers.

The lifting block 4 is integrally conical and is formed by welding steel bars; the through hole 6 is fixedly provided with a conical frame 8 matched with the lifting block 4, the conical frame 8 is formed by welding steel bars, and the stability of the cover plate 5 is ensured in the lifting, supporting, below and covering processes by utilizing the conical guiding and positioning principle, so that the cover plate 5 is effectively prevented from deflecting or skewing.

The cover plate 5 comprises a keel frame 51 and an iron sheet plate 52, and the iron sheet plate 52 is welded on the keel frame 51.

Finally, it is noted that the above-mentioned preferred embodiments illustrate rather than limit the utility model, and that, although the utility model has been described in detail with reference to the above-mentioned preferred embodiments, it will be understood by those skilled in the art that various changes in form and detail may be made therein without departing from the scope of the utility model as defined by the appended claims.
