The objective of the invention is to solve the problem that exists in the above-mentioned prior art, provide a kind of when using the kind of drive of Dual-motors Driving,, can both guarantee the portal crane lock of locking behind the dodge gate door-closing in-place of the left and right sides no matter whether dodge gate operation in the left and right sides is synchronous.
For addressing the above problem, the technical scheme that the present invention adopts is a kind of portal crane lock of structure, comprising: be fixed on the lock body on the installing plate; Being located in the lock body can upper and lower mobile jam plate, and this jam plate upper end is connected with a driven unit; One penetrate in the lock body can left and right slip carriage release lever, this carriage release lever is provided with jam plate and inserts the notch of extracting, carriage release lever one end is provided with pin shaft hole; One through pivot pin and the hinged fork of carriage release lever; One is positioned at the swivel hook that lock body one side is connected with fork 4 through bearing pin, and this swivel hook is provided with the capable groove of the U that cooperates with the dodge gate rotor; In the moving process that dodge gate is opened or closed, transmission body is hit the U-lag of swivel hook at positive and negative both direction, makes its rotation that produces positive and negative both direction, drives the move left and right of carriage release lever again through fork, and realization is unblanked or lock operation.
The present invention also comprises a manual unlocking arm, described jam plate lower end when it is in locked position with can drive its manual unlocking arm that moves up against.
Described driven unit comprises an electromagnet; Insert the traction iron core that this electromagnet lower end is connected with said jam plate; Be set with a compression spring on this traction iron core, an end of this compression spring is resisted against on the said electromagnet, and the other end is resisted against on the steady pin that is fixed on the said traction iron core.
Said lock body is provided with two and vertically leaves spacing side by side, each other, the photoelectricity travel switch of induction jam plate shift position.
The pin shaft hole that is connected with fork of described carriage release lever one end setting is a mounting hole, the convenient installation.
The portal crane lock of the present invention design has automatically and the manual unlocking function, its compact conformation, and required component are few, each component processing is convenient, and it is simple, easy to maintenance to have an installation, and the advantage of stable performance is adapted at using on subway platform safety door, the automatic door.
Description of drawings
Below in conjunction with accompanying drawing and embodiment the present invention is done further explanation, wherein:
Fig. 1 is positioned at the sketch map that closes the lock state for preferred embodiment of the present invention;
Fig. 2 is positioned at the sketch map of unlocking condition for preferred embodiment of the present invention;
Fig. 3 is the lateral view of the said embodiment of figure.
The specific embodiment
As shown in Figure 1, the portal crane lock of the present invention's design comprises: be fixed on the lock body 2 on the installing plate 1; Being located in the lock body can upper and lower mobile jam plate 6, this jam plate one end with can drive the upper and lower mobile driven unit 15 of jam plate and be connected; One penetrate in the lock body can left and right slip carriage release lever 10, this carriage release lever is provided with the notch 12 that can supply jam plate to get into, carriage release lever one end is provided with pin shaft hole, and is hinged through the mounting hole that is provided with on pivot pin 3 and the fork 4; One is positioned at the swivel hook 11 that lock body one side is connected by the lock body support holes, and the bolster on the swivel hook 11 is connected with fork 4 through bearing pin 5; Also comprise two photoelectricity travel switches 12 and 13 that the vertical induction jam plate shift position of leaving spacing side by side, is each other used that lock body is provided with.
As shown in Figure 1; The upper end of jam plate 6 is connected with driven unit 15; The described driven unit of this driven unit comprises an electromagnet 7, inserts the traction iron core 9 that this electromagnet lower end is connected with said jam plate 6, is set with a compression spring 8 on this traction iron core; One end of this compression spring is resisted against on the said electromagnet 7, and the other end is resisted against on the steady pin that is fixed on the said traction iron core 9.The lower end of jam plate 6 when it is in locked position with can drive manual unlocking arm 14 that said jam plate 6 moves up against.Manual unlocking arm 14 breaks down at driven unit, and when needing manual unlocking, but plate is started unlocking arm 14, pushes the jam plate 6 disengaging carriage release lever notch 12 that moves up.
In the present embodiment, be equipped with U-lag on the swivel hook 11, the transmission body that the U-lag on the swivel hook 11 and is fanned on the dodge gate cooperates, and makes a body locking.During use, left and right sides dodge gate is respectively joined the portal crane lock of a cover symmetrical structure.The mode that two fan dodge gates respectively adopt a motor to add synchronous band or wheel and rack drives; Hit the U-lag of swivel hook 11 in the moving process that dodge gate is opened or closed at positive and negative both direction through transmission body; Drive the positive and negative rotation of swivel hook 11, realize the move left and right of carriage release lever 10 again through fork 4.In the course of work, when the door machine controller sends when instruction of opening the door, the suction of electromagnet will draw iron core and upwards inhale mobile; Make the U-lag mouth disengaging configuration that moves on the plate 6 with carriage release lever 10, plate 6 has blocked the optical axis of vertical top one photoelectricity travel switch 12 simultaneously, and enabling signal is imported controller into; The motion of under the drive of motor, opening the door of two dodge gates in the U-lag of the transmission body on the dodge gate on swivel hook 11, is hit swivel hook 11; Swivel hook 11 is rotated; Drive fork again and rotate, move right door lock place released state thereby drive carriage release lever 10.In the locking process, in the U-lag that is moved into swivel hook 11 of the transmission body on the dodge gate along with dodge gate, oppositely hit swivel hook 11; Make swivel hook 11 backward rotation; Be moved to the left and drive carriage release lever 10, when two dodge gate door-closing in-places, controller sends instruction and removes electromagnet 7 suction; Plate 6 is at the elastic force of spring 8 and under the promotion of gravity, move down and get in the notch of carriage release lever 10; Plate 6 blocks the optical axis of a vertical following photoelectricity travel switch 13 simultaneously, and sends portal crane lock locking signal to controller, accomplishes to close the lock action.
When closing the door the rotor bump swivel hook 11 of dodge gate, the bolster on the swivel hook 11 drives fork 4 and rotates, thereby drives carriage release lever 10 move left and right.Lock body is provided with the photoelectricity travel switch 12 and 13 that two vertical induction jam plate shift positions of leaving spacing side by side, are each other used.
The present invention is used for the platform half-height safety door, and the locking and the unlatching of the motion of major control left and right sides dodge gate are during use; Left and right sides dodge gate is respectively joined the portal crane lock of a cover symmetrical structure; During the dodge gate door-closing in-place, can pin door, in the left and right sides when need open the door; Ability automatic unlocking and manual unlocking, thus guarantee that the platform dodge gate uses safely and reliably.
