Abstract
The utility model discloses a collapse prevention protection device that falls is prevented weighing down by anchor rope under deep mining condition, including anchor rope tray and well -bucket, the well -bucket is fixed in the lower part at anchor rope tray center, the well -bucket in arranged disc and lower disc, the anchor rope tray, go up the disc, open on disc and the well -bucket and have the centre bore that supplies the anchor rope to pass down, last disc upper end be fixed with with anchor rope fixed connection's tool to lock, lower disc card in the well -bucket lower part, last disc and the spring of a suit on the anchor rope be equipped with down between the disc, the even symmetrical arrangement in well -bucket upper end has a plurality of rings, rings pass through the hoist cable and link to each other with roof metal mesh or steel band, through the combination of each component, utilize the transmission effects of power, and reduction mechanism, can play good preventing to the anchor rope of slip and the anchor rope under the high stress state and weigh down the collapse prevention effect that falls, provide the guarantee for operation workman's in the tunnel life safety.
Description
Technical field
This utility model is related to a kind of anti-fall anti-avalanche protection device of anchor cable under the conditions of deep mining, more particularly to a kind of coal
Under the conditions of ore deposit deep mining, anchor cable breaks, anti-fall to prevent directive tunnel protection device.
Background technology
At present, in process of coal mining, bolting with wire mesh is used as one of current roadway support most effective way, and anchor cable
One of main support unit as bolting with wire mesh, plays vital effect in bolting with wire mesh.With mining depth
Increase, crustal stress is increasing, and geological conditions also becomes extremely complex.Under these conditions, the anchor under high-stress state
There is breaking phenomenon in Suo Jiyi and the anchor cable that breaks can produce under certain conditions huge impulsive force, and directive tunnel is caused
Casualty accident.Certainly, falling for anchor cable breaks, for the life security of operating worker in tunnel become one it is huge
Threaten.
The content of the invention
In order to improve such case, it is to avoid anchor cable falls the generation of casualty accident, now devises a kind of deep-well condition and casts anchor
The anti-fall anti-avalanche protection device of rope.
This utility model is achieved through the following technical solutions：The anti-fall anti-avalanche protection dress of anchor cable under the conditions of a kind of deep mining
Put, including anchor cable pallet and well-bucket, well-bucket is fixed on the bottom of anchor cable tray center, be disposed with described well-bucket disk and
Lower disc, is provided with the centre bore passed through for anchor cable, described upper disk upper end on anchor cable pallet, upper disk, lower disc and well-bucket
The lockset being fixedly connected with anchor cable is fixed with, described lower disc is stuck in well-bucket bottom, between described upper disk and lower disc
Equipped with a spring being sleeved on anchor cable, well-bucket upper end is symmetrically disposed with some suspension ring, and suspension ring are by hoist cable and top
Sheetmetal net or steel band are connected.
It is further：Described suspension ring are arranged at 30～50mm of well-bucket upper end.
It is further：Described well-bucket is the assembly of cylinder and semicircle spherical shell.
It is further：Described well-bucket is arranged symmetrically four suspension ring at cylindrical upper same level position.
It is further：Described hoist cable is galvanized wire.
The beneficial effects of the utility model are：This utility model combines cushioning principle and force resolution principle, energy
Enough impulsive forces produced when breaking by anchor cable under high-stress state absorb decomposes, and prevents anchor cable from falling suddenly directive tunnel, together
When for anti-fall effect can also be played due to the anchor cable that a variety of causes slip is ruptured, improve the safety coefficient in tunnel, it is ensured that
The normal operation of workman.
Description of the drawings
Fig. 1 is this utility model structural representation；
In figure：1st, anchor cable, 2, anchor cable pallet, 3, lockset, 4, upper disk, 5, spring,
6th, lower disc, 7, well-bucket, 8, suspension ring, 9, hoist cable.
Specific embodiment
This utility model is described further below in conjunction with the accompanying drawings.
As shown in figure 1, this utility model device includes upper disk 4, lower disc 6, spring 5, well-bucket 7, suspension ring 8 and galvanized wire,
Described upper disk 4, lower disc 6 and spring 5 are arranged in well-bucket 7；Centre bore, energy are provided with the middle of upper disk 4 and lower disc 6
Enough ensure that anchor cable 1 is passed right through, two disk middle settings, one spring 5 plays cushioning effect；Well-bucket 7 is cylinder and semicircle
The assembly of spherical shell, has a hole, it is ensured that anchor cable 1 can just pass through in the bottom of spherical shell.Apart from the upper end 50mm of well-bucket 7
Where be provided with four suspension ring 8, arrange in cross-shaped symmetrical along well-bucket 7, it is ensured that uniform stressed, with galvanized wire by itself and top board gold
Category net or steel band are connected.
During work, because lockset 3 is suspended in anchor cable 1 and anchor cable pallet 2 on top board, so to anchor cable 1, the and of lockset 3
Anchor cable pallet 2 is not altered.Only upper disk 4, spring 5, lower disc 6, well-bucket 7 need to be sequentially passed through anchor cable 1, and by well-bucket
Four galvanized wires of suspension ring 8 of end are connected on the reinforcing bar at top, ladder beam or wire netting.Answer when the slip of anchor cable 1 and high
Break under power state ejection when, the impulsive force and gravity moment that upper disk 4 produces anchor cable 1 passes to spring 5, then spring 5 will
Power uniformly passes to anchor cable pallet 2, and power is passed to well-bucket 7 by anchor cable pallet 2 again, and well-bucket 7 transmits the force to again the galvanized wire being attached thereto
On, because the galvanized wire being connected with top board has four, this is equivalent to the impulsive force quartering for producing anchor cable 1, is weakened,
So as to prevent falling and ejection for anchor cable 1, the safety coefficient of operation in tunnel is improve, be the life of operating worker in tunnel
Guarantee is safely provided.
