Description
Technical field
The present invention relates to traction elevator, especially relate to a kind of traction elevator and limit slip device at the traction elevator that rear restriction lift car out of service is smooth.
Background technology
At present, what the brake mode after traction elevator (hereinafter referred to as elevator) is out of service adopted is that after relying on spring force to grant brake block or liner, compressing is braked parts stop with elevator traction sheave is rigidly connected, and its feature is the soft braking relying on friction force.This braking force be also elevator out of service after make car keep the power of quiescence.Therefore, about the technical security standard of elevator is all to which proposing requirement, in China for the elevator before putting into operation and annual regular inspection elevator, all must do unloaded up and 125% rated load is descending, whether the power-off test under normal operating speed, check the braking potential of elevator brake to meet the demands thus.But, elevator is in real-world operation, often due to the artificial adjustment of retarding spring power or the wearing and tearing of ANOMALOUS VARIATIONS, brake block or gasket contacts or heating carbonization, elevator brake ability is caused to decline, light then cause lift car to rush to summit or squat at the end, heavy then the casualty accident causing passenger to be sheared or fall, this kind of elevator accident happens occasionally.
Cause the root of the accident to be elevator technology safety rate does not limit the issuable smooth amount of elevator out of service because elevator is smooth, causes and does not all prevent the substantial safety-design that elevator is smooth with elevator now.After elevator generation is smooth, drg will reduce until disappear gradually to the friction force being braked parts generation, thus cause lift car smooth until accelerate out of control.Given this, increase elevator limit slip device, the smooth amount of restriction elevator ought to become the essential requirement of elevator.
Chinese patent CN202967788U discloses a kind of Anti-slip protection device for elevator, comprise main control unit, band-type brake validation switch, photoelectric code disk, first relay, second relay, wire holder and panalarm and power subsystem unit, band-type brake validation switch is arranged on elevator internal contracting brake, photoelectric code disk is arranged on the velocity limiter that is connected with the car of elevator, wire holder is installed on the steel rope side of elevator, band-type brake validation switch, band-type brake contacts of contactor switch, photoelectric code disk, the drive end of the first relay and the second relay is connected with main control unit respectively, the open contact K switch 1 of the first relay is connected in the supply line of wire holder, the open contact K switch 2 of the second relay is connected in the supply line of panalarm.The present invention can start wire holder and stop car to continue to move when elevator slips car phenomenon, report to the police simultaneously, remind related personnel to keep in repair elevator in time, improve the safety that elevator runs.
Summary of the invention
The object of the invention is to for existing elevator out of service rear because brake ability declines the smooth problem of lift car that causes, a kind of traction elevator limit slip device that can realize controlling in the smooth amount of rear car out of service elevator is provided.
The present invention is provided with pivoted arm, 2 rollers, 2 roller brackets, 4 pieces of roller guide plates, 2 pieces of voussoirs, electromagnet, tumbler spring, pivoted arm support and supports, and support is provided with lower plate and upper plate;
Described pivoted arm is a cross bar, and on the equidistant position of pivoted arm pivot point both sides, diagonal angle is provided with protrusion, and protrusion is provided with a hole, and pivoted arm is connected with roller bracket by rotating shaft, and roller bracket can along axis of rotation; Roller bracket is provided with groove, and roller is placed in groove, and the axis hole on the centre hole alignment roller bracket of roller also penetrates roller axle; Pivoted arm support vertical is between upper plate and lower plate and connect into support, and 2 pieces of voussoir reverse vertical are fixed between the upper plate of support and lower plate; Pivoted arm is installed on pivoted arm support, and the two ends of roller axle are inserted in the guide groove be located on roller guide plate by 2 pieces of roller guide plates respectively, and 2 pieces of roller guide plates are bolted on voussoir both sides, and tumbler spring is connected between pivoted arm and support; Electromagnet is arranged on support, and its position is adjustable, and the dynamic iron of electromagnet inserts in the electromagnet jack be located on pivoted arm.
When the present invention uses, first complete the assembling of each parts, then sedan-chair top upper beam (or bottom girder at the bottom of sedan-chair) former car the present invention being arranged on elevator is led boots position and fixes; Adjustment roller and cage guide gap, namely utilize electromagnet to move the position of iron, and rotation pivoted arm to two roller face tangent line is equal with the gap between guide pass, fixed electromagnet; Finally, car is led boots to be loaded on above the present invention.
Controlling electromagnet actuating signal of the present invention is connected in series given by following four signals: the smooth amount of car (pulse produced by the rotary encoder intercepts) signal set after brake coil dead electricity signal, layer door and gate start signal, Elevator landing signal and Elevator Stop, this smooth amount is generally set between the half length of 0 ~ toe guard of elevator car.Setting signal controls electromagnet action of the present invention by it after first controlling intermediate relay again.
When electromagnet action, electromagnet moves iron and departs from pivoted arm, pivoted arm rotates by the effect of tumbler spring power, and drive roller carriage rotation, converting rotary motion is the straight-line motion of edge guiding by its rotating shaft by roller bracket, and roller is pushed to contact with cage guide face, now, no matter car slip on continuing or under slip, the tangential force produced between roller face tangent line and guide pass is forced to voussoir by making the roller on wherein one side, make it between car guide rail and voussoir, to produce enough horizontal compressions by roller, stop car continues smooth.When pivoted arm rotates, cut off elevator safety loop, elevator issuable maloperation when avoiding this device to work simultaneously.Just think that manually car loosens along smooth reverse jiggering to roller by jiggering mode, can hand reset the present invention under making and preventing the smooth measure of elevator.
The invention has the beneficial effects as follows, overcome existing elevator in the rear smooth problem of lift car caused because brake ability declines out of service, can realize controlling in the smooth amount of rear car out of service elevator, thus eliminate the generation of Gao Frequency accident in elevator use.
