Description
Technical field
The utility model is related in mine shaft hoist system technical field in coal mining more particularly to mine shaft hoist system
First-rope hinger, and in particular to head rope hangs the quick loosening device of wedge rope_ring.
Background technology
First-rope hinger is the important attachment device that hoisting container is connect with boom hoist cable, energy in mine shaft hoist system
Enough play the role of balance rope tension difference and adjustment container upper and lower opening parking position.Since boom hoist cable is using process
Middle applied elongation must carry out adjusting rope construction once more than the adjustable range of first-rope hinger.And in first-rope hinger
Can wedge rope_ring quickly loosen in adjusting rope work progress exits, and plays the role of to the length of construction time critical.
In mine shaft hoist system boom hoist cable according to《Safety regulations in coal mine》Regulation, the general replacement period be 2 years.
And boom hoist cable is very fast since steel wire rope stress changes at newly installation initial stage, needs to carry out 4-5 within 1 year or so time
Secondary tune rope work.Wedge rope_ring is the important component for locking boom hoist cable in first-rope hinger, is needed in adjusting rope work
Loosening exits the wedge rope_ring in first-rope hinger in order to play boom hoist cable, due to normal wedge rope_ring self-locking original
Wedge rope_ring caused by being influenced by coal dust, water drenching in reason and running environment is difficult to loosen.The loosening work used in the prior art
There are mainly three types of tools：First, beating the method that bar taps wedge rope_ring using sledgehammer.Bar will be made to be put into wedge rope_ring, duty
Work, which holds sledgehammer and taps 30 minutes or more, could loosen a wedge rope_ring.It is primarily present following drawback：1）This operation belongs to well
Cylinder working at height causes prodigious threat along with fierce sledgehammer of brandishing is tapped to the personal safety of operating personnel.2）When percussion
It is easy to cause the damage of hoisting rope and wedge rope_ring.3）Low construction efficiency, construction time are long.Second is that impacting wedge shape rope using pneumatic pick
The method of ring.Pneumatic pick head is put into wedge rope_ring, worker, which holds pneumatic pick and impacts 20 minutes or so, could loosen a wedge shape
Becket bridle.It is primarily present following drawback：1）This operation belongs to pit shaft working at height, along with pneumatic pick and pipeline are heavier, construction
It is inconvenient and be easy to cause pit shaft pendant object.2）The damage of hoisting rope and wedge rope_ring is be easy to cause when impact.3）Low construction efficiency is applied
Work time is long.Third, utilizing the method for screw thread principle top pine wedge rope_ring.It makes a special long screw thread and is put into wedge shape
In becket bridle, worker holds spanner and rotates thread looseness wedge rope_ring.It is primarily present following drawback：1）Since wedge rope_ring is stuck in head
Stress in suspension arrangement of restricting is larger, and worker using spanner is difficult rotation screw thread and spanner is easy to slip out of the hand, threaded top and sleeve
Equal contacts site are easily deformed, and construction is inconvenient and be easy to cause pit shaft pendant object.2）Low construction efficiency, construction time are long.

A kind of vertical shaft hoisting head rope suspension wedge rope_ring quickly loosens structure, including rope hoisting device, promotes steel wire
Rope, wedge rope_ring attachment device, the wedge rope_ring attachment device include the wedge rope_ring that wedge is carried on the back, is caught in the wedge back of the body, promote steel
Cord is sleeved on outside wedge rope_ring, wedge rope_ring and the tight boom hoist cable of wedge back splint, and dovetail groove is arranged at the top of wedge rope_ring, described
Wedge rope_ring quickly loosens the quick loosening device that structure further includes described, and the quick loosening device setting connects in wedge rope_ring
The trapezoid block of connection device upper end, quick loosening device lower end is inserted into the dovetail groove, and lower end and the wedge rope_ring of pusher rod hang down
Direct-connected to connect, the baffle on quick loosening device top is fixed by vertical derrick.
The beneficial effects of the utility model：
This vertical shaft hoisting head rope, which hangs the quick loosening device of wedge rope_ring, is made to measure according to wedge rope_ring design feature
Specific purpose tool, it is easy to operate, it is highly practical, alleviate operating personnel's labor intensity, improve work efficiency, safety coefficient
Large increase is obtained.It efficiently solves old technology loosening wedge rope_ring to be difficult to loosen, boom hoist cable is in suspension arrangement
It is difficult to the problem of play.The activity duration for exiting a boom hoist cable wedge rope_ring is loosened at 6 minutes or so, is avoided in well
Cumbersome tools, dangerous instruments are used when cylinder working at height, it is ensured that the personal safety of construction personnel shortens the construction time, carries

Specific implementation mode
Embodiment 1
As shown in Figure 1, 2, a kind of vertical shaft hoisting head rope that is applied to hangs the quick loosening device of wedge rope_ring, including top
Baffle 1, two connecting rods 3 being fixedly connected with baffle both sides, the trapezoid block 4 being fixedly connected with the lower end of two connecting rods 3, the ladder
Through-hole is arranged in 4 middle part of shape block, and a pusher rod 5 is passed through in through-hole, and there are one jack 2 for setting between pusher rod 5 and baffle 1.
Through-hole is the circular through hole of a diameter of 32mm, and the pusher rod 5 is the circular shaft of a diameter of 30mm.The jack is 8T hydraulic pressure thousand
Jin top.
Embodiment 2
As shown in figure 3, a kind of vertical shaft hoisting head rope suspension wedge rope_ring that is applied to quickly loosens structure, including steel wire rope carries
Device, boom hoist cable 7 and wedge rope_ring attachment device are risen, the wedge rope_ring attachment device includes the wedge back of the body 8, is caught in the wedge back of the body
Wedge rope_ring 6, boom hoist cable 7 is sleeved on outside wedge rope_ring 6, and wedge rope_ring 6 clamps boom hoist cables 7, wedge shape with the wedge back of the body 8
Dovetail groove is arranged in 6 top of becket bridle.Quick loosening device setting in embodiment 1 is in wedge rope_ring attachment device upper end, quick pine
The trapezoid block 4 of dynamic device lower end is inserted into the dovetail groove, lower end and 6 vertical connection of wedge rope_ring of pusher rod 5（It restricts with wedge shape
The contact point of ring is vertical）, the baffle 1 on quick loosening device top fixed by vertical derrick.
The operation principle of wedge becket bridle attachment device：After wedge rope_ring, the tight steel wire rope of wedge back splint, tension device is screwed,
Using the upward pulling force of boom hoist cable, the main rope band of boom hoist cable moves wedge rope_ring and moves up, and is carried on the back using wedge rope_ring, wedge
Between friction, clamping steel wire rope, due to the upward pulling force of hoisting rope, wedge rope_ring is continued to move up until auto lock is
Only.
The operation principle of loosening device：The utility model gradually applies pressure using jack to wedge rope_ring, makes wedge shape
