Description

Lifting device for subway shaft

Technical Field

The utility model relates to a subway shaft construction field specifically is subway shaft hoisting device.

Background

The shaft is excavation and the passageway of transporting secret silt or silt during subway construction, and the shaft well head goes out to need to set up hoisting device and is used for transporting the material, and present hoisting device needs the workman to pull the material outside the shaft edge from directly over the well head after promoting the material to the well head, then topples over the material, because pulling of the reaction force of material, the workman falls in the well easily, in addition, frequent toppling over the material also makes workman's amount of labour great.

Disclosure of Invention

To the above-mentioned condition, for overcoming prior art's defect, the utility model provides a subway shaft hoisting device, the effectual subway shaft hoisting device that has solved causes the workman to fall easily and the big problem of workman's amount of labour.

The technical scheme of its solution is, subway shaft hoisting device, including erectting the support at the shaft well head, the support mounting has two parallel and interval arrangement's slide rail, two slide rails all incline to arrange, the one end of slide rail extends the well head top, the other end is located the well head edge outward, the one end that the slide rail is located the well head top is less than the other end, be equipped with a pulley between two slide rails, thereby the both sides of pulley are installed in the slide rail through a litter respectively and are made the pulley can slide along the slide rail, the higher one end of slide rail is equipped with a hoist engine of fixing on the support, twine the lifting rope on the hoist engine, the pulley is walked around and be connected with the lifting hook to the free end of lifting.

The utility model discloses the danger of falling easily when effectively having avoided the workman to pull the well bucket outward from the well head upper side, and alleviateed workman's the amount of labour greatly.

Detailed Description

The following detailed description of the embodiments of the present invention will be made with reference to the accompanying drawings.

By figure 1 to 6, the utility model discloses an erect support 1 at the shaft well head, support 1 installs two parallel and interval arrangement's slide rail 2, two slide rail 2 all incline to arrange, the one end of slide rail 2 extends the well head top, the other end is located the well head edge outward, the one end that slide rail 2 is located the well head top is less than the other end, be equipped with a pulley 3 between two slide rails 2, thereby the both sides of pulley 3 are installed respectively through a litter 4 and are made pulley 3 can slide along slide rail 2 in slide rail 2, the higher one end of slide rail 2 is equipped with a hoist engine 5 of fixing on support 1, twine lifting rope 6 on hoist engine 5, pulley 3 is walked around to the free end of lifting rope 6 and is connected with lifting hook 7, lifting hook 7 has well bucket 8.

The upper end of the lifting hook 7 is fixed with four horizontal stop rods 9 which are evenly distributed on the circumference, and when the lifting hook 7 is lifted to the stop rods 9 to be contacted with the lower side of the sliding rail 2, the lifting hook 7 can not be lifted upwards any more.

A horizontal cross rod 10 is fixed on the support 1 and is positioned outside the edge of a shaft well mouth of the vertical shaft, and when the bucket 8 is pulled outwards towards the edge of the vertical shaft, the horizontal cross rod 10 can block the middle part of the bucket 8 to enable the bucket 8 to turn.

The utility model discloses when using, after splendid attire material in the well was transferred to well bucket 8, start hoist engine 5, hoist engine 5 promotes well bucket 8 through rolling lifting rope 6, after the lower side that promotes shelves pole 9 on lifting hook 7 and slide rail 2 contacted, lifting hook 7 will not upwards promote again, hoist engine 5 continues rolling lifting rope 6 and will stimulate pulley 3 and move to the outside along slide rail 2 this moment, thereby with the pulling of well bucket 8 to well head outer fringe, after the middle part and the horizontal cross pole 10 contact of well bucket 8 lateral wall, lifting rope 6 continues to stimulate well bucket 8 upper end and can make well bucket 8 overturn around horizontal cross pole 10, empty out the material in the well bucket 8.

After the material has been poured, reverse start hoist engine 5 is released lifting rope 6, and under the effect of gravity, pulley 3 slides to the inner of slide rail 2, drives well head 8 and removes to well head top, and behind pulley 3 removed the 2 tip of slide rail, continue to release lifting rope 6 and can transfer well head 8 into in the shaft.

The utility model discloses a slide rail 2 that the slope set up makes can move outside the well head automatically after well shaft well head is promoted out to well bucket 8, and the upset effect of cooperation horizontal pole 10 makes well bucket 8 empty the material automatically, and the workman only need auxiliary control well bucket 8 can, the danger of falling easily when having avoided the workman to draw well bucket 8 outward from the well head upper direction, and has alleviateed workman's the amount of labour greatly.
