Abstract
The invention discloses a device for preventing an elevator cage from abnormally moving. The device comprises a braking mechanism installed on a cage large beam, a reset mechanism arranged at one end of the braking mechanism, and an electrical detecting mechanism. The braking mechanism comprises a shell. A U-shaped action jaw is arranged on one lateral side of the shell. An elevator T-shaped guide rail is located in the U-shaped action jaw. Electromagnets and brake pads are symmetrically arranged on the two sides of the U-shaped action jaw. The brake pads are installed at the ends of the electromagnets and are stretched out and drawn back under the control of the electromagnets so as to clamp and release the elevator T-shaped guide rail. The electrical detecting mechanism comprises a magnetic strip installed on the elevator T-shaped guide rail and a magnetic strip sensor opposite to the magnetic strip. The magnetic strip sensor is installed on the side, with the U-shaped action jaw, of the shell. By the adoption of the mechanical and electrical integration design, the device has the advantages of being capable of conducting detection and recognition automatically, high in response speed and short in braking length.
Description
Technical field
The present invention relates to a kind of lift car accessory, more particularly to a kind of device for preventing lift car extremely mobile.
Background technology
At present, Chinese having turned into possesses the most country of elevator in the world, has 2,400,000 elevators operating daily, averagely
Every people more than 500 just possesses an elevator, and the annual speed with 15% is increasing.The increase of elevator quantity, makes repair and maintenance work
Amount increase, many elevators are not in place because repair and maintenance work, or lift facility is aging etc., and reason causes the security incident of elevator to increase,
Wherein, the triggered security incident of car movement frequently occurs in the case of enabling, and under elevator door opening, traditional elevator has
Two ways prevents elevator from moving, and one is main frame brake, but the device acts on position of host machine, it is impossible to prevent steel wire rope from draging
Skidding on running wheel or because of the movement of the brake car that failure causes in itself；Two is car safety, due to car safety
Pincers uses gradual, and by limiter of speed it must be triggered to act in the case of more than normal speed, therefore braking distance
It is excessive, far beyond the safe allowed band in door area.
The content of the invention
A kind of defect it is an object of the invention to overcome prior art, there is provided dress for preventing lift car extremely mobile
Put, by using sensor detecting and magnet switching mode, it is possible to achieve when door-opened elevator region car is extremely mobile,
Lift car is locked on guide rail.
To achieve the above object, the present invention proposes following technical scheme：
A kind of device for preventing lift car extremely mobile, it is characterised in that：Including the brake on car crossbeam
Arrestment mechanism, resetting-mechanism and electric testing agency located at skidding mechanism end, the skidding mechanism bag
Housing is included, the side of the housing one is provided with U-shaped action jaw, and elevator T type guide rail is located in the U-shaped action jaw, described U-shaped
Action jaw is symmetrically arranged on two with electromagnet and brake block, and the brake block is arranged on electromagnet end, and in the control of electromagnet
Stretched out under system and retracted to clamp and unclamp T-shaped guide rail, the electric testing agency includes the magnetic on elevator T type guide rail
Bar and the magnetic stripe sensor relative with the magnetic stripe, the magnetic stripe sensor have the side of U-shaped action jaw installed in housing.
Institute's rheme magnetic stripe sensor connection elevator control cabinet.
The offset distance of 2 ~ 5cm is preset with the magnetic stripe sensor.
The skidding mechanism, resetting-mechanism and electric testing agency are all connected with UPS electric power systems.
Compared with prior art, what the present invention was disclosed prevents the extremely mobile device of lift car, is detected using sensor
Car is moved up and down limitation within the specific limits by technology during door is opened, and quick and precisely judges car position, works as sedan-chair
The position in railway carriage or compartment is under door opening and when apparatus for controlling elevator does not send operating instruction, once sensor detects car anon-normal
Often mobile, be locked at car on guide rail by trigger relay ejection brake block, and it uses Electromechanical Design, possesses automatic
Detection, automatic identification, fast response time, the short advantage of braking distance prevents elevator from the potential safety hazards such as shearing, extruding occur, from
And passenger safety is seen in protection.
Brief description of the drawings
Fig. 1 is the structural representation that the present invention prevents the extremely mobile device of lift car.
Specific embodiment
Below in conjunction with accompanying drawing of the invention, the technical scheme to the embodiment of the present invention carries out clear, complete description.
As shown in figure 1, a kind of disclosed device for preventing lift car extremely mobile, specifically includes brake
Arrestment mechanism 1, electrically resetting-mechanism 2 and testing agency 3, and the skidding mechanism 1, electrically resetting-mechanism 2 and detection machine
Structure 3 is all connected with UPS electric power systems.
Particularly, the skidding mechanism 1 is arranged on car crossbeam, and it includes shell 4, the side of the shell 4
U-shaped action jaw 5 is provided with, elevator T type guide rail 10 is placed in the U-shaped action jaw 5, with U-shaped action jaw in the shell 4
Electromagnet 6 is arranged with centered on 5, the end of the electromagnet 6 is provided with brake block 7, and the brake block 7 is led positioned at elevator T type
The both sides of rail 10, and the T-shaped guide rail of clamping is stretched out under the control of electromagnet 6, while retracted under the control of electromagnet 6 unclamping T-shaped
Guide rail 10.
The resetting-mechanism 2 is SR, and it is arranged on the end of skidding mechanism 1, connects the electromagnet 6, when
When needing releasing of brake piece 7, the resetting-mechanism 2 is manually pressed by so that electromagnet 6 is powered off, so that releasing of brake piece 7.
The electric testing agency 3 includes magnetic stripe 8 and magnetic stripe sensor 9, and the magnetic stripe 8 is arranged on elevator T type guide rail 10
On, the magnetic stripe sensor 9 is arranged on the side that shell 4 is provided with U-shaped action jaw 5, and the magnetic stripe sensor 9 and the magnetic
Bar 8 is oppositely arranged, the connection of magnetic stripe sensor 9 elevator top switch board, and is connect when running contactor in switch board and braking
When tentaculum is without triggering, magnetic stripe sensor 9 works, and the magnetic stripe sensor 9 is also connected with electromagnet 6, to go out the work of solenoid 6
Make, while the offset distance of 2 ~ 5cm is preset with the magnetic stripe sensor 9, when more than default offset distance, magnetic stripe sensing
The trigger electromagnet 6 of device 9 so that brake block 7 stretches out to clamp T-shaped guide rail 10.
A kind of device for preventing lift car extremely mobile disclosed in this practical information, its operation principle is：Elevator is arrived
The device is started working after being opened the door up to floor, and now magnetic stripe sensor 9 starts to detect car position, while detecting fortune in control cabinet
