Description

No machine room home lift rescue cabinet

Technical field

The utility model relates to a kind of elevator rescue cabinet, especially a kind of no machine room home lift rescue cabinet.

Background technology

Inorganic machine room free elevator since its have effectively utilize space, can be suitable for various hoisting depths flexibly widely, building operation is simply saved, elevator is installed advantages such as easy, applied more and more widely.

When traditional inorganic machine room free elevator runs into the situation of power failure suddenly; General emergency relief method is that the drg with actuating device declutches; Utilize the car of elevator and the unbalanced weight of counterweight to make lift car move up or down, if this moment, car was heavy, car will move downward; If this moment, counterweight was heavy; Car, just can be saved out with upward movement near cage operation arrives the flat bed zone with the personnel that are trapped in the car; When but if car and counterweight are in state of equilibrium basically; Even the drg of actuating device declutches, car can up-and-down movement yet, can not realize rescuing function.

Thereby application number be in the patent of CN01811464.4 disclosed technical scheme through breaking the state of equilibrium between car and the counterweight installing urgent counterweight on the belt conveyor additional; Thereby regulating urgent counterweight pulling belt conveyor drive car moves up or down; If but after the emergency relief work completion; Urgent counterweight after elevator resumes operation, might cause the miscellaneous part on urgent counterweight and the elevator to impact because rescue group's careless omission is forgotten takes off; Thereby make elevator serious fault occur, for this reason this patent through intelligent manner more avoided using urgent counterweight increases that elevator breaks down maybe.

The utility model content

The purpose of the utility model provides the rescue cabinet that rescue appears carrying out after the oppressive fault in a kind of inorganic machine room free elevator.

For addressing the above problem; The utility model provides a kind of no machine room home lift rescue cabinet; Comprise monitoring module, communication module, protection module and control module; Described monitoring module is the monitoring display terminal, and described protection module comprises and be arranged on rescue earth leakage circuit breaker cashier's office in a shop, and described control module comprises and is arranged on the rescue operation of control elevator and halt switch and the door open button that stops the elevator operation cashier's office in a shop.

In the hoistway at elevator place monitoring detector is set and is arranged on rescue monitoring display terminal cashier's office in a shop and cooperate the operation that to monitor elevator effectively.Monitoring detector comprises two; Be separately positioned on the outside and lift car inside of lift car, the situation that monitoring detector can be monitored the exterior running condition of elevator and inner elevator of elevator or passenger simultaneously be set simultaneously in lift car inside and lift car outside.

The two ends of door open button are connected on a machine frequency converter enabling signal end and an enabling signal common port respectively.

As preferably, described communication module is an interphone.

As preferably, described earth leakage circuit breaker is 290 circuit breakers.

290 circuit breakers are a kind of neutrality earth leakage protective devices over the ground; Usefulness mainly as earth leakage protective; Also can be used to prevent because of apparatus insulated damage; The fire hazard that produces earth fault and cause, and can be used to the overload and the short circuit of protection circuit and electrical motor, also can be used as the usefulness of the not frequent starting of circuit.

As preferably, described interphone possesses to prestore in local telephone network function and the interphone and is not more than five groups of telephone numbers.

Interphone possesses the local telephone network function can get in touch maintenance or rescue group effectively when Lift out of order; Prestore in the interphone and be not more than five groups of telephone numbers and can prevent; Certain number is sought other rescue groups after putting through failure at short notice more again; Accelerate rescue speed, avoid taking place bigger loss.

As preferably, described control module also comprises the emergency management and rescue key, up button, the descending descending button of control elevator of button, control ascending for elevator of declutching has a power failure.

Descending button is through control relay, and relay normally open contact is closed when pressing descending button, makes common port and its Enable Pin of frequency converter, direction end and the conducting of speed end, and frequency converter is received instruction back output driving host;

Up button is through control relay, and relay normally open contact is closed when pressing up button, makes common port and its Enable Pin of frequency converter, direction end and the conducting of speed end, and frequency converter is received instruction back output driving host;

After the emergency management and rescue key was stamped, elevator got into inspecting state, simultaneously the main contactor adhesive;

When Lift out of order is in state of equilibrium; Inject the emergency management and rescue key to the emergency management and rescue key; Press the button that declutches that has a power failure, make the frequency converter driving host disequilibrate by the upstream or downstream button again, elevator is risen to level position; Discharge button and the upstream or downstream button of declutching that have a power failure, press door open button again and discharge trapped personnel.

As preferably, described control module comprises that also power-transfer clutch key, motor are just changeing button and motor invert button.

After the power-transfer clutch key was stamped, the power-transfer clutch closure made rescue motor transmission shaft and motor shaft link together through power-transfer clutch;

Motor is just changeing button makes the running of rescue motor positive dirction;

The motor invert button makes the running of rescue motor reversing sense;

When Lift out of order is in state of equilibrium; After stamping emergency management and rescue key and power-transfer clutch key to emergency management and rescue key and power-transfer clutch key; Make small machine be connected with electric machine main shaft; Pressing has a power failure, and the button box motor that declutches is just changeing button or motor invert button, and elevator is risen to that discharging behind the level position has a power failure and declutch button is just changeing button or motor invert button with motor, presses door open button release trapped personnel again.
