Description
Technical field
The utility model relates to take off door lock with electromagnetic type is anti-on a kind of door lock more particularly to a kind of vertical lift.
Background technique
It is announced according to State Statistics Bureau, until 2015 year end 13.7462 hundred million people of China's Mainland, 7.7 hundred million people of cities and towns permanent resident population,
2.52 hundred million people of floating population.Conservative estimation, China have more than 2,000,000,000 person-times of seating elevators daily, elevator be in social activities not
The vertical transport tool that can lack.In the end of the year 2015, elevator annual output about 70.4 ten thousand, ownership is up to 425.96 ten thousand, annual output
And ownership all ranks first in the world.
China's elevator high load, large conveying quantity, long period use generally existing, old elevator quantity surge, elevator safety master
Body responsibility is unable to effective execution, especially elevator maintenance industry harmful competition, and maintenance work is not in place etc., cause elevator accident and
Failure happens occasionally.
According to 11.2.1 requirements in GB7588-2003 " elevator manufacture and installation safety standard ", elevator shaft inner surface
It is no more than 0.15m with the horizontal distance maximum at the nearest doorway edge of car sill, carriage door frame or sliding door.It is above-mentioned to provide
Spacing: 1) rise to 0.20m, height is not more than 0.50m；2) for the cargo lift using vertically sliding door, whole
This spacing rises to 0.20m in a stroke；If 3) carriage equipped with mechanical interlocking door and can only be in the unlocking area of floor door
It opens, the operation of elevator should automatically depend on the locking of gate, and gate locking must be filled by satisfactory electrical safety
It sets to confirm, then above-mentioned spacing is unrestricted.
In GB7588-2003 " elevator manufacture with installation safety standard " No. 1 modification list of national standard, 8.11.2 in order to
It limits personnel in carriage and opens gate, the measure that should provide makes: when a) carriage is run, the power for opening gate should be greater than 50N；B) carriage
When except region defined in 7.7.1, apply the power of 1000N at enabling limits device, gate is opened no more than
50mm.8.11.3 at least open corresponding layer behind the door when in distance as defined in carriage is parked in 9.11.5, can not have to tool from
Stop opens gate, unless the tool with triangle key or permanent setting at the scene.This requirement, which is also applied for having, to be met
8.9.3 the gate of car door lock.
Elevator in the process of running, if gate is fitted without mechanical locking device, only controls motor by controller
The unlatching of work positions carriage with stopping, separately having part to rely on the door motor with holding torque to guarantee the closing shape of gate
State.However, can be opened easily if elevator failure makes door motor；Or elevator, in operational process, gate is strong
After row is pushed aside, once elevator is not in level position, sedan-chair, passenger there is greatly security risk, fall hoistway there are personnel
With the security risk being sheared.
Utility model content
In order to avoid continually debugging, electrical safety circuit is removed or be shorted to gate mechanical lock in violation of rules and regulations, gives elevator
Operation leaves great security risk, and the purpose of this utility model is to provide take off door with electromagnetic type is anti-on a kind of vertical lift
Lock.

Power loss can change the opening and closing lock status of movable hook 10, the movable inside for being installed on shield 3 of electromagnetic coil 5.In fixed plate 1
Leading exterior surface offer the first screw hole 2 close to the position of upper end, the lower end of fixed plate 1 is fixedly installed with fixed bottom plate 7, Gu
Fixed board 1 is movably installed with electrical contact 6 close to the side lower end of movable base plate 9.
Wherein, through there is the first screw, fixed plate 1 passes through the first screw and lift car activity for the inside of the first screw hole 2
Connection, the first screw pass through the first screw hole 2 to fixed lift car.
Movable base plate 9 is movably installed with mobile contact 11 close to the side of fixed plate 1, and mobile contact 11 with electrical to touch
First 6 with the use of reaching the opening and closing of gate, and electrical contact 6 and mobile contact 11 are located at same vertical plane, mobile contact 11 to
The opening and closing for reaching gate is used cooperatively with electrical contact 6.The activity installation respectively of the leading exterior surface upper and lower ends of movable base plate 9
There are the first pin shaft 13 and the second pin shaft 14, the leading exterior surface of movable base plate 9 offers the second spiral shell far from the side of fixed plate 1
Hole 12.Wherein, through there is the second screw, the movable base plate 9 passes through the second screw and lift car for the inside of the second screw hole 12
It is flexibly connected.
Stay hook 8 is fixedly connected with bottom plate 7.Stay hook 8 can be located at same vertical plane with movable hook 10, and movable hook 10 can
It is stuck in stay hook 8.Side of the movable hook 10 far from fixed plate 1 is separately connected with the second pin shaft 14, and the second pin shaft 14 being capable of band
Dynamic movable hook 10 is lifted up.First pin shaft 13 is identical as 14 specification size of the second pin shaft.The upper end outer surface of fixed bottom plate 7
Movable to be equipped with fixed screw, the fixed bottom plate 7 can be flexibly connected by fixed screw with lift car.Movable hook 10
One end is fixed on movable base plate 9, and the other end can be by engagement in rotation on stay hook 8, and movable hook 10 and stay hook 8 are fixed
In the two sides of elevator cage door for lockking lift car.
Door lock is taken off with electromagnetic type is anti-on a kind of vertical lift of the utility model, previous carriage stops ladder in non-unlocking district domain
It is oppressive, often greatly inconvenient and trouble is brought to rescue work.Setting gate mechanical lock can no doubt prevent unsafe
It saves oneself behavior, to avoid something therefore can occur, but also bring inconvenience to rescue work simultaneously, if it is elevator professional people
Member, then to overhaul or urgent electric operation or even the mobile carriage to unlocking area of the jiggering that declutch after, gate could be opened and released multiply
Visitor；If operating unfamiliar fire-fighting and rescue personnel to elevator rescue to show up, it is more likely that destructive rescue is implemented to gate,
After installing that gate is anti-additional and taking off mechanical lock, due to part gate mechanical lock mounting and adjusting not in place or sole mass problem causes elevator therefore
Barrier rate is very high, gate mechanical lock when causing safety return circuit obstructed or leveling that is easy to appear gate mechanical lock electrical contact poor contact
Latch hook can not break off relations completely causes elevator malfunction accident, therefore has part maintenance staff in order to avoid continually debugging, and disobeys
Electrical safety circuit is removed or be shorted to rule gate mechanical lock, leaves great security risk to elevator operation.
Then, it by fixing seat and is moved the utility model proposes taking off door lock with electromagnetic type is anti-on the vertical lift, when use
Dynamic pedestal passes through the first screw and the second screw through being fixed on elevator cage door in the first screw hole 2 and the second screw hole 12 respectively
Two sides, when the area lift car Bu Men stops, 5 power loss of electromagnetic coil on elevator cage door in shield 3,14 band of the second pin shaft
Dynamic movable hook 10 is latched, and electrical contact 6 and mobile contact 11 are closed, and reaches closing gate, passenger user in lift car
Power can not open gate, and after elevator reaches door area, the electromagnetic coil 5 in shield 3 obtains electric, the second pin shaft 14 drive movable hook
10 are lifted up, and electrical contact 6 and mobile contact 11 disconnect, gate can smooth opening, most of existing elevators can be solved not
Meet the requirement of the 11.2.1 item in GB7588-2003.
The above is only the preferred embodiments of the present utility model only, is not intended to limit the utility model, all practical at this
Made any modifications, equivalent replacements, and improvements etc., should be included in the guarantor of the utility model within novel spirit and principle
Within the scope of shield.
