Interchanger is simultaneously connected with the program controlled telephone two-wire in well inner working face, hole top signal room, the room of winch 22, and telephone configuration earphone fills in well
Put, include major loop with hole top signal personnel depaly wireless interspeaker, the control circuit of hoisting gear 22 in well and (protected containing decompression
Shield, controlled motor turns to and speed governing etc.), loop of testing the speed, safety return circuit (linkage of lock containing work, overtravel protection etc.), control loop
(control loop containing adjustable brake, decelerating phase overspeed protection control loop, dynamic braking control loop), adjust rope locked loop, depth
The composition such as indicator loop and subsidiary loop is spent, relay occurs for 1 signal of being connected between major loop and safety return circuit, respectively
It is connected with the safety contactor in the dynamic braking contactor and safety return circuit in control circuit major loop, the construction winch 22
The control circuit of winch 22 just can turn on and start winch 22 after operating personnel are connected to and send cue, the hoisting gear
22 voltage loss protecting systems are connected with overtravel protection, dynamic braking control loop, are connected in o-volt protection with overtravel protection circuit
Increase by 1 preventing colliding with top limit switch 26, be connected respectively with overtravel protection switch, pulleying reset switch, the construction wellhead 21 pushes up
Portion sets up position 1 limiter 25, and limiter 25 is connected with limit switch of rushing to summit, and the limiter 25 is hit rear limit switch
Disconnect, decompression protector automatism, promote the main safety switch separating brake power-off of the dynamic braking control loop of winch 22, winch 22
The work lock interlocking carried automatically resets and braking of closing a floodgate, winch 22 stop lifting.Tunnel shaft provided by the utility model is applied
22 technology safe to use of work winch, simple in construction, installation is easy, and Meteorological is low, and signal command system is safe and reliable, realizes and twists
The electric-control system of car 22 organically combines with signal contacted system, safe to use, and it is safe to use to improve tunnel shaft construction winch 22
Coefficient.Thus, the limiter 25 set up is spacing after being hit to open in 25 failure of limiter on the depth indicator of winch 22
Shut-off is opened, decompression protector automatism, promotes the main safety switch separating brake power-off of the control system of winch 22, the work of winch 22
Make lock interlocking to automatically reset, winch 22 stops lifting.
Communicating with the scheme of signal contacted system 02 is：18 SPC telephone exchange, two-wire are installed in hole top signal room
Lay, and extension set is installed respectively in well inner working face, the room of winch 22, work team director, mechanical director, work team's strong point, wherein
In well phone band Headphone device, while well in and hole top signal personnel depaly wireless interspeaker.Work hanging scaffold, hole top signal in well
Electric bell is installed in room, the room of winch 22 respectively, and electric bell rings 1 sound, 2 sound, 3 sound, 4 sound, 5 sound and indicates respectively that the work of winch 22 operates winch 22
Stop, at a slow speed lifting, at a slow speed decentralization, fast lifting, quickly transfer well-bucket 24 or hanging scaffold.Signal box and the room wind of winch 22 are also pacified respectively
5 signal lamps are filled, wherein 1 signal lamp represents that winch 22 stops, 2 signal lamps represent that operation winch 22 hoppet 24 or is hung at a slow speed
Disk, 3 signal lamps represent that operation winch 22 transfers at a slow speed well-bucket 24 or hanging scaffold, and 4 signal lamps represent the operation fast lifting well-bucket 24 of winch 22
Or hanging scaffold, 5 signal lamps represent that operation winch 22 quickly transfers well-bucket 24 or hanging scaffold.Indicator lamp numbering is corresponding with number of rings, such as rings
The sound of bell 1, then No. 1 indicator lamp is bright.Construction the electrical system rebuilding technical scheme of winch 22 be：Winch 22 dispatch from the factory design electric-control system be
It is independent when the operation of winch 22 is in preparation operation, safety protection loop and o-volt protection can not connect with signal system and make
With, when cager does not signal, the operative employee of winch 22 still can arbitrarily operate winch 22 to be lifted, down maneuver,
Therefore easily there is maloperation, it is difficult to ensure safely.In addition, winch 22 can only be by single depth indicator scale when being lifted, declined
" 5ck " and " 6ck " limiter 25 come complete safety return circuit protection, can only be joined in the case of o-volt protection by manual operation separating brake
Lock, winch 22 is easily rushed to summit when being lifted beyond the predetermined home of well head, and causes serious security incident.Therefore, skill
Art transforms one：When the operation of winch 22 is in preparation level, safety protection loop and voltage loss protecting system are connected with signal system
Using, i.e., 1 interface end is opened between " 4c " and " 37 " of automatically controlled circuit, insertion 1 signal of series connection sends relay, that is,
When signalman sends lifting or step-down operation indication signal, just connected between circuit " 39 " and " 37 ".So transform, strand can be made
The operative employee of car 22 could operate winch 22 after being only connected to signal, can avoid maloperation, and technological transformation two is：To o-volt protection
Part is transformed, and prevents the pulleying of winch 22 from rushing to summit.It is deep when winch 22 is lifted beyond the predetermined home of well head before transformation
Limiter 25 (" 5ck " and " 6ck " in Fig. 2) on degree indicator scale is touched, and makes contactor tripping operation power-off, and safety is returned
Road protection starts.But if the failure of limiter 25, then winch 22 can not cut off self-lock, and easily cause the accident of rushing to summit, therefore in control line
1 preventing colliding with top limit switch 26 is increased with cascade between road " X11 " and floor push " JTK ", while pushed up from derrick 21
Portion 12m positions install 1 limiter 25 additional, and limiter 25 connects limit switch.When 25 failure of limiter on depth indicator,
Well-bucket 24 touches the limiter 25 on derrick 21, disconnects limit switch, decompression protector automatism, promotes main safety switch
Separating brake powers off, and the work lock interlocking of winch 22 automatically resets, and lifting stops.
Above-described is only some embodiments of the present utility model.For the person of ordinary skill of the art,
On the premise of not departing from the utility model and creating design, various modifications and improvements can be made, these belong to practical new
The protection domain of type.
