Summary of the invention

The purpose of this utility model provides the elevator cage door locking device that just can open when a kind of car door that can guarantee elevator has only with layer Men Zaitong one deck.

The utility model can be implemented by the following technical programs: a kind of elevator cage door locking device, it comprises that being fixed on each hits bow on the door gear layer by layer, be fixed on the gate lock slide plate that but along continuous straight runs slides on the machine slide plate and touch the fork bottom deck assembly, be fixed on the lock of the gate on bank mount pad on the gate door machine, it comprises that also but along continuous straight runs is slidingly arranged in the gate lock adapter plate on the described gate lock mount pad, be arranged on the gate latch hook on the described gate lock adapter plate rotationally with opening, be arranged on the roller on the described gate latch hook regularly, be connected the extension spring on described gate lock mount pad and the described gate lock adapter plate, described gate lock slide plate touches on the fork bottom deck assembly has lock dog, described lock dog has locking and two states of release, when described lock dog is in the lock state, described lock dog is inserted in the described opening, and described gate lock slide plate touches the fork bottom deck assembly and pushes against on described gate lock adapter plate; When described lock dog was in released state, described lock dog broke away from described opening, when described lock dog from lock-out state to the process of released state conversion, described roller pushes against described and hits on the bow.

Have the hole on described gate latch hook, be set with latch hook by ball on described gate lock adapter plate, described latch hook is positioned at described hole by ball.

Described gate latch hook is connected with described gate lock adapter plate axle.

Compared with the prior art the utility model has following advantage: when elevator cage door is opened after cage operation arrives certain one deck, door machine slide plate moves to both sides, gate lock slide plate on the door machine slide plate touches the fork bottom deck assembly and is moved to the left and drives gate lock latch hook and be moved to the left, along with touching the fork bottom deck assembly, gate lock slide plate is moved to the left originally pushing against the gate lock adapter plate that touches on the fork bottom deck assembly at gate lock slide plate under the pulling force of extension spring, latch hook continues toward moving to left when the roller on the gate latch hook is run into gate lock and hit bow, and the gate lock roller that is fixed on the gate latch hook can't continue to be moved to the left, the gate latch hook is swayed begin to tilt, until on the gate latch hook latch hook in the hole by ball restriction gate latch hook till can not rotate, car opens at this moment.If the car door of elevator is not opened car door with layer door with one deck the time, gate latch hook gate lock roller when moving to left just can not be against the gate lock that is installed on layer door gear and not hit bow, just can run-off the straight not make lock dog break away from opening, therefore can't open the gate of elevator, guarantee passenger's safety.

The specific embodiment

As accompanying drawing 1 to the elevator cage door locking device shown in the accompanying drawing 8, it comprises that being fixed on each hits bow 3 on the door gear layer by layer, be fixed on the gate lock slide plate that but along continuous straight runs slides on the machine slide plate 9 and touch fork bottom deck assembly 1, be fixed on the lock of the gate on bank mount pad 4 on the gate door machine, it comprises that also but along continuous straight runs is slidingly arranged in the gate lock adapter plate 7 on the described gate lock mount pad 4, be arranged on the gate latch hook 2 on the described gate lock adapter plate 7 rotationally with opening 10, be arranged on the roller 6 on the described gate latch hook 2 regularly, be connected the extension spring 5 on described gate lock mount pad 4 and the described gate lock adapter plate 7, described gate lock slide plate touches on the fork bottom deck assembly 1 has lock dog 8, described lock dog 8 has locking and two states of release, when described lock dog 8 is in the lock state, described lock dog 8 is inserted in the described opening 10, and described gate lock slide plate touches fork bottom deck assembly 1 and pushes against on described gate lock adapter plate 7; When described lock dog 8 was in released state, described lock dog 8 broke away from described opening 10, when described lock dog 8 from lock-out state to the process of released state conversion, described roller 6 pushes against described and hits on the bow 3.

Have hole 11 on described gate latch hook 2, be set with latch hook by ball 12 on described gate lock adapter plate 7, described latch hook is positioned at described hole 11 by ball 12.

Described gate latch hook 2 and described gate lock adapter plate 7 pivotal joints.

When elevator cage door is opened after the cage operation of elevator arrives certain one deck, door machine slide plate 9 moves to both sides, gate lock slide plate on the door machine slide plate 9 touches fork bottom deck assembly 1 and is moved to the left, also, gate lock slide plate is moved to the left originally pushing against the gate lock adapter plate 7 that touches on the fork bottom deck assembly 1 at gate lock slide plate under the pulling force of the extension spring 5 that compresses along with touching fork bottom deck assembly 1, the latch hook 2 that is arranged on the gate lock adapter plate 7 also is moved to the left, roller 6 on being arranged on gate latch hook 2 is run into the gate lock and is hit past the moving to left of latch hook 2 continuation when bending 3, and the gate lock roller 6 that is fixed on the gate latch hook 2 can't continue to be moved to the left, gate latch hook 2 is swayed begin to tilt, until on the gate latch hook 2 latch hooks in the hole 11 by ball 12 restriction gate latch hooks 2 till can not rotate, the opening of car this moment.If the car door of elevator is not opened car door with layer door with one deck the time, gate latch hook 2 gate lock roller 6 when moving to left just can not be against the gate lock that is installed on layer door gear and not hit bow 3, just can run-off the straight not make lock dog 8 break away from opening 10, therefore can't open the gate of elevator, guarantee passenger's safety.

When closing car door, gate lock slide plate touches fork bottom deck assembly 1 promotion gate lock adapter plate 7 and moves right, gate latch hook 2 left side under the effect of gravity falls, until the latch hook in the hole 11 makes gate latch hook 2 can't continue to move by ball 12, at this moment gate latch hook 2 maintenance levels and described lock dog 8 are inserted in the opening 10, even lift car gate lock is in the lock state.
