Abstract

The utility model which provides a dynamic stowage lifting device of a mine-used shaft skip relates to a hoist, a headgear pulley, a wire rope and a skip, and the wire rope in the vertical direction which bypasses the headgear pulley is convolved on the hoist; the skip is suspended on the wire rope in the vertical direction; water is used as the dynamic stowage material, and the bottom of the skip is a dynamic stowage water tank; the wellhead which is on the top of the vertical wire rope is provided with a wellhead quantitative filling water system while the bottom is provided with a well-bottom unloading water system which is connected with a water sump in the well bottom. By adopting the dynamic stowage lifting device, the hoisting capacity of the shaft skip and the productivity can be improved without changing the situation of the force of the hoisting equipment.

Description

The dynamic prestowage bont of mining vertical shaft skip

Technical field:

The utility model relates to the dynamic prestowage bont of a kind of mining vertical shaft skip, is used for the elevator system of mine vertical.

Background technology:

The mine shaft hoist system of mine all adopts skip bucket fixed type counterweight now, can't improve the capacity weight of skip bucket, has limited the hoisting capacity of main shaft hooist system.

Summary of the invention:

The purpose of this utility model provides the dynamic prestowage bont of mining vertical shaft skip, is not changing under the stressed situation of lifting means, improves the hoisting capacity of vertical shaft skip.

The purpose of this utility model realizes as follows: it relates to gig, headgear pulley, steel rope and skip bucket, the steel rope of vertical direction is walked around headgear pulley and is wrapped on the gig, skip bucket is suspended on the steel rope of vertical direction, the bottom of skip bucket is dynamic prestowage case, top at vertical steel rope has well head to fill loading system, and the shaft bottom uninstalling system is arranged in the bottom.

For ease of filling unloading, filling the load material that unloads in dynamic prestowage case is fluid, generally in economy easily under the situation, selects water as the dynamic medium of prestowage.

Because elevator system is in lifting process, one in the skip bucket on the steel rope of both sides is equipped with mineral matter, and a zero load so just makes between steel rope and the elevator drum and skids, so original elevator system just is equipped with fixing prestowage on skip bucket.This device has removed fixing prestowage material, and the weight of the prestowage material that will remove has changed actv. load into.Promptly the skip bucket in the shaft bottom is equipped with the capacity weight that the capacity weight that is equivalent to original-pack mineral matter such as coal etc. adds prestowage weight summation, fill with dynamic prestowage at the discharged skip bucket of well head such as water, the skip bucket that promotes the shaft bottom, back rises to the well head unloading and annotates the load of prestowage, the skip bucket of well head drops to the shaft bottom prestowage load is laid down, load onto and be equivalent to former prestowage and the need lifting material that promotes thing weight sum, go round and begin again like this, promptly keep the former tension parameter constant of elevator system, but improved hoisting capacity effectively.

Utilize the dynamic prestowage bont of this mining vertical shaft skip, do not changing under the stressed situation of lifting means, improve the hoisting capacity of vertical shaft skip, also just improved productive capacity.With the model be the lifting container of JWPGY-12/110 * 4 to promote coal be example, 12 tons of former skip bucket load-carryings reduce 4 tons of its counterweights, just can increase by 4 tons load carrying ability, become 16 tons by 12 tons, skip bucket has increased by 4 tons of coal lifting amounts at every turn.

Description of drawings:

Accompanying drawing is the structural representation of the dynamic prestowage bont of the mining vertical shaft skip of the utility model.

The specific embodiment:

With reference to accompanying drawing, it relates to gig 1, headgear pulley 2, steel rope 3 and skip bucket 6, the steel rope 3 of vertical direction is walked around headgear pulley 2 and is wrapped on the gig 1, skip bucket 6 is suspended on the steel rope 3 of vertical direction, as dynamic prestowage material, the bottom of skip bucket 6 is dynamic prestowage water tank 5 with water, at the well head place, top of vertical steel rope 3 the quantitative water filling system 4 of well head is arranged, there is the shaft bottom to unload water system 7 in the bottom, unloads water system 7 and link to each other with wellhole 8.

Be applied as example with the colliery: when skip bucket 6 rises to well head, quantitatively the operated pneumatic valve of water filling system 4 water tanks is opened, when skip bucket 6 is unloaded coal, water is charged in the skip bucket 6 bottom water tanks, filling time is identical with unloading time, the quantitative water filling system 4 of well head is realized detecting automatically and automatic guidance, and the unloading situation was identical when another skip bucket 6 arrived well head, reaches the purpose of skip bucket 6 dynamic prestowages; When dress water skip bucket 6 arrived the shaft bottom loading point, the valve open of skip bucket 6 water tank bottoms unloaded water, and skip bucket 6 is coaling simultaneously, after loading is finished, water in the water tank also enters sump by the water receiving facility, and it is synchronous to unload water time and loading time, reaches the purpose of skip bucket 6 dynamic prestowages.

Claims

1, the dynamic prestowage bont of a kind of mining vertical shaft skip, relate to gig, headgear pulley, steel rope and skip bucket, the steel rope of vertical direction is walked around headgear pulley and is wrapped on the gig, skip bucket is suspended on the steel rope of vertical direction, it is characterized in that: the bottom of skip bucket (6) is a dynamic prestowage case (5), top at vertical steel rope (3) has well head to fill loading system (4), and shaft bottom uninstalling system (7) is arranged in the bottom.

2, the dynamic prestowage bont of mining vertical shaft skip according to claim 1 is characterized in that: filling the load material that unloads in dynamic prestowage case (5) is fluid.
