Abstract

The invention discloses a lower vertical bore-hole gangue drop prevention device which mainly comprises a bucket, lifting lugs, lifting ropes, an adhesive tape, a winch, a steel wire rope, a guide pulley, a lifting ring, a roadway, a top plate and a coal bunker. The winch is mounted in the roadway; the guide pulley is fixed on the top plate; four lifting lugs are uniformly welded on the circumference of the bucket; the four lifting lugs on the bucket are respectively connected with the lifting ring by virtue of the lifting ropes; the steel wire rope on the winch is connected with the lifting ring by virtue of the guide pulley; the adhesive tape is spread in the bucket; the bucket is suspended in the coal bunker; and the position of the bucket in the coal bunker can be adjusted by starting or stopping the winch, so that the operating space of workers in the vertical bore-hole of the coal bunker is adjusted. The invention has the beneficial effects that the lower vertical bore-hole gangue drop prevention device provided by the invention is suspended in the vertical bore-hole of the coal bunker, gangue dropping in the coal bunker automatically enters the device. The condition that the gangue continuously drops and injures people is avoided, and the construction safety in the vertical bore-hole of the coal bunker is improved.

Description

Lower coal founds eye anti-spoil drop device

Technical field

The present invention relates to coal mine equipment, be related specifically to lower coal and found eye anti-spoil drop device.

Background technology

Coal bunker is in the place carrying out interim storage coal at the bottom of coal mine, existing coal bunker construction frequently with method be First hole with rig, then form greatly coal bunker by artificial brush, owing to the vertical depth of coal bunker is relatively deep, executing There is many potential safety hazards during work, at vertical eye cover plate suitable for reading, coal bunker mouth is covered in, coal can be prevented Storehouse is stood eye your west suitable for reading and is fallen into coal bunker, and founds intraccular part for coal bunker and fall cash and cannot solve, and is expanding brush coal bunker During, coal bunker to be watched out for founds the spoil that intraccular part drops, although in construction period, coal bunker adheres to that striking side asks Top, cleaning country rock crag cash alive, but this method can not be fully solved the problem that cash is hurted sb.'s feelings, especially Installing pre-buried bucket perforating, powder charge at coal bunker end opening, during the operation such as pouring construction, the spoil dropped will be to work Industry personnel produce extremely serious consequence, and existing conventional method is to use steel pipe built to lay plank in coal bunker, The spoil fallen in coal bunker is blocked outside operation area, but this method labor strength is big, security reliability Difference, the working environment of workman is severe, and the lower coal of therefore invention one founds eye anti-spoil drop device, to solving mesh Front coal bunker safety work hidden danger has great importance.

Summary of the invention

It is an object of the invention to for existing deficiency, it is provided that lower coal found eye anti-spoil drop device, prevent The cash that falls in coal bunker is hurted sb.'s feelings, and improves safety during coal bunker end opening operation.

The technical scheme is that and be achieved in that: lower coal founds eye anti-spoil drop device, mainly include hanging Bucket, hanger, lifting rope, adhesive tape, winch, steel wire rope, leading block, suspension ring, tunnel, top board, coal Storehouse, winch is arranged in tunnel, and leading block is fixed on top board, uniform welding 4 lifting on well-bucket circumference Ear, 4 on well-bucket are played hanger and are coupled with suspension ring by lifting rope respectively, and well-bucket is suspended in coal bunker, winch On steel wire rope couple with suspension ring through leading block, be covered with adhesive tape in well-bucket.

The lower coal that the present invention provides founds eye anti-spoil drop device, and winch is arranged in tunnel, and leading block is solid Determining on top board, the steel wire rope on winch couples with suspension ring through leading block, and suspension ring are further through lifting rope and well-bucket Couple, well-bucket be suspended in coal bunker, by start and stop winch, well-bucket position in coal bunker can be regulated, Found the working space of ophthalmic at coal bunker with regulation workman, on well-bucket circumference, uniform welding 4 plays hanger, well-bucket On 4 play hangers and coupled with suspension ring by lifting rope respectively, by coupling of four hangers and suspension ring, can With the stability preferably keeping well-bucket to be suspended in coal bunker, when making spoil drop in well-bucket, well-bucket is unlikely In producing bigger rocking, in well-bucket, it is covered with adhesive tape, when spoil drops in well-bucket, not direct and well-bucket On the contact of hard steel plate, but fall on the adhesive tape in well-bucket, by the cushioning effect of adhesive tape, relatively great Cheng Degree alleviate the cash impact to well-bucket, improve well-bucket stability spatially and service life, work When people carries out the operation such as perforating, powder charge in coal bunker, only well-bucket need to be raised to suitable position, operating personnel Position, below well-bucket, can carry out various operation safely.

The invention has the beneficial effects as follows: the lower coal of offer founds eye anti-spoil drop device, and device is suspended in coal bunker Vertical ophthalmic, automatically in this device after in coal bunker, spoil falls, it is to avoid spoil continues to fall and hurts sb.'s feelings, improves Coal bunker stands the safety of ophthalmic construction.

Detailed description of the invention

The invention will be further described below in conjunction with the accompanying drawings, as shown in Figure 1: lower coal founds the anti-spoil of eye and falls dress Put, mainly include well-bucket 1, play hanger 2, lifting rope 3, adhesive tape 4, winch 5, steel wire rope 6, leading block 7, suspension ring 8, tunnel 9, top board 10, coal bunker 11.

Described lower coal founds eye anti-spoil drop device, as it is shown in figure 1, away from coal bunker 11 center suitable for reading 8～10m Installing a JD-14T type winch 5 in the tunnel 9 at place, leading block 7 is arranged on directly over coal bunker 11 center Top board 10 on, the steel wire rope 6 pile warp leading block 7 on winch 5 stretches in coal bunker 11, with coal bunker 11 Interior suspension ring 8 couple, and suspension ring 8 are to use the round steel of a diameter of 20mm to bend to form, and well-bucket 1 uses polylith Thickness is that the Plate Welding of 8mm forms, and bung a diameter of 1200mm hangs down to bung bottom well-bucket 1 a height of 800mm, lays adhesive tape 4 in well-bucket 1, and on the ladle body at well-bucket 1 bung, uniform welding 4 plays hanger 2, the steel plate that a hanger 2 uses thickness to be 12mm is made, long 80mm, wide 50mm, is playing hanger 2 center Position is drilled with the hole of Φ 25mm, and lifting rope 3 is that the steel wire rope using a diameter of 18.5mm is made, lifting rope 3 One has passed the centre bore on hanger, and has connected with wire clips is fixing, and other end passes suspension ring 8, also uses wire clips Being fixedly connected, four are played hanger 2 and are all connected with suspension ring 8 by lifting rope 3, make well-bucket 1 be suspended in coal In storehouse 11, the operating personnel in coal bunker 11 hides under well-bucket, it is possible to safe carries out operation in various storehouse, Although combining accompanying drawing above to describe embodiments of the present invention, but those of ordinary skill in the art also may be used To recognize that these modifications and variations should be managed in scope of the following claims, various changes can be made or amendment Solve as within the scope of the present invention and intention.
