Description
Technical field
The utility model is related to mine hoisting system field more particularly to a kind of mine hoist overwinding-proof protective devices.
Background technology
During mine shaft building, the depth indicator of mine hoist is equipped with limit switch, and the limit of depth indicator is opened
Pass is connected in the relay coil circuit in mine hoist safety circuit, occurs to disconnect when pulleying, and relay electric-loss action, realization stops
Electricity and emergency braking, play the purpose for preventing pulleying.The limit switch of depth indicator is only relied on to realize overtravel protection, once
Limit switch malfunction and failure will cause overtravel protection to fail, if promotion speed is larger, overwind trouble, or even hair will occur
The pernicious major accidents such as raw disconnected rope pendant tank, cause heavy economic losses and casualties.
Utility model content
The technical problem to be solved by the utility model is to provide a kind of mine hoistings strengthening the protection to elevator
Machine overwinding-proof protective device.
The utility model is to solve above-mentioned technical problem by the following technical programs：Mine hoist overwinding-proof protection dress
It sets, including depth indicator, Weight type limit switch (1), suspension strop (2) and spacing ring (3), the suspension strop (2) is connected to
On the actuating arm of the Weight type limit switch (1), the spacing ring (3) is suspended on the weight by the suspension strop (2)
The steady tank rope (6) of the lower section of formula limit switch (1), elevator passes through the spacing ring (3), the Weight type limit switch (1)
It is connected on jointly in the relay coil circuit in mine hoist safety circuit with the pulleying limit switch of the depth indicator.
Technical solution as an optimization, the Weight type limit switch (1) are fixed on derrick panel (4).
Technical solution as an optimization is connected to the behaviour of the Weight type limit switch (1) in the middle part of the suspension strop (2)
On swing arm, both ends are connected to the both sides of the spacing ring (3) of circular ring shape.
Technical solution as an optimization, the suspension strop (2) use steel wire rope.
Technical solution as an optimization, the spacing ring (3) use steel loop.
The utility model has the advantage of：The pulleying limit switch of depth indicator plays dual with Weight type limit switch
The effect of protection strengthens the protection to elevator, avoids the overwind trouble during shaft construction, improves mine hoist
The safety coefficient of operation.
Description of the drawings
Fig. 1 is the structural schematic diagram of the utility model mine hoist overwinding-proof protective device.
Specific implementation mode
As shown in Figure 1, mine hoist overwinding-proof protective device, including it is depth indicator, Weight type limit switch 1, outstanding
Lanyard 2 and spacing ring 3.
Elevator is suspended on by hoisting rope 5 and steady tank rope 6 in mine, and the top of elevator is equipped with tank deck cap 7.
Weight type limit switch 1 is fixed on derrick panel 4, and the middle part of suspension strop 2 is connected to Weight type limit switch 1
On actuating arm, both ends are connected to the both sides of the spacing ring 3 of circular ring shape, and spacing ring 3 is suspended on Weight type by suspension strop 2 and limits
The steady tank rope 6 of the lower section of bit switch 1, elevator passes through spacing ring 3.
The pulleying limit switch of Weight type limit switch 1 and depth indicator be connected on jointly mine hoist safety circuit after
In electric apparatus coil circuit, in the case that the pulleying limit switch of Weight type limit switch 1 and depth indicator is all connected, relay
Device is attracted, elevator normal operation.The pulleying limit switch of depth indicator is as back-up protection, with Weight type limit switch 1
Play the role of duplicate protection, strengthens the protection to elevator.
Suspension strop 2 is using the steel wire rope of a diameter of 6.2mm, and spacing ring 3 is using steel loop.
In the case of normal hoisting, due to the pulling force that the dead weight of spacing ring 3 generates, the actuating arm of Weight type limit switch 1
It is pulled down, Weight type limit switch 1 is closed, safety return circuit connection, elevator normal operation.
When elevator rise to tank deck cap 7 touch be further continued for after spacing ring 3 rising when, spacing ring 3 loses to Weight type
The pulling force of limit switch 1, Weight type limit switch 1 disconnects, and to make safety return circuit disconnect, the brake apparatus startup of elevator makes
Elevator stops in time, plays the purpose for preventing pulleying.
Length under the natural suspension status of suspension strop 2 from the actuating arm of Weight type limit switch 1 to spacing ring 3, which is more than, to be promoted
Maximum braking distance when machine is with maximum speed uplink plays the mesh for preventing pulleying to provide enough braking buffer time
's.
The above is only the preferred embodiment of the present invention, is not intended to limit the utility model, all in this practicality
All any modification, equivalent and improvement etc., should be included in the guarantor of the utility model made by within novel spirit and principle
Within the scope of shield.
