Sole 107 and the second toeguard 108 are reverse folded.
First fixed frame 101 and the second fixed frame 102 are guide rail structure, and first connecting rod 105, second connecting rod 106 can be along phases
Corresponding fixed frame movement, to adjust the position of connection.
The slewing area of main hinge 109 be 0~180 °, when the second toeguard 108 be fully deployed to the first toeguard 107
In same plane, main hinge 109 goes to 180 ° of extreme position.
Foldable toe guard of elevator car further includes locking mechanism.As shown in Figure 5 and Figure 6, locking mechanism includes being fixed on first
Triangulation chain 201 on toeguard 107 is fixed on the first toeguard 107 by triangulation chain 201 and keeps same with triangulation chain 201
It walks the locking bar 202 rotated, the latch hook 203 being fixed on locking bar 202 and the second toeguard 8 is fixed on by the second fixed frame 102
On lock tube 204, the lock tube 204 coordinates the latch hook 203 to lock the second toeguard 108, the triangulation chain 201, locking bar
202, latch hook 203 and lock tube 204 be in the same plane.In order to prevent locking bar 202 it is long and drop or fracture, the locking bar 202
It is connect with car platform by the hook 207 on the first fixed frame 101, the hook 207 is for triggering locking bar 202.
In order to detect the state of foldable toeguard, first toeguard 107 is equipped with limit switch 205, the second shield
Sole 108 is equipped with the feeler lever device 206 that triggering limit switch 205 acts, when the second toeguard 108 folds, feeler lever device
206 triggering limit switches 205 are closed, elevator normal operation；When second toeguard 108 is unfolded, limit switch 205 disconnects, elevator
Into inspecting state.
Foldable toe guard of elevator car expansion provided by the utility model and folding work process description are as follows：
When elevator needs maintenance, inserts a key into triangulation chain 201 and rotate, locking bar 202 and be fixed on locking bar 202
Latch hook 203 rotates simultaneously, until latch hook 203 produces lock tube 204.Under the driving of air spring 110, first connecting rod 105 and
Two connecting rods 106 are rotated around bearing 112, until first connecting rod 105 is blocked with 111 phase of bending edges on second connecting rod 106；It is same with this
When, the second toeguard 108 is rotated around main hinge 109, until being expanded to the first toeguard 107 in same plane.Second spats
After plate 108 is unfolded, limit switch 205 is disconnected with feeler lever device 206, and the signal transmission that the second toeguard 108 is unfolded is to control
Circuit processed, control elevator cannot be run up and down, and elevator enters inspecting state.At this point, foldable toeguard is fully deployed and is in
Self-locking state can bear the thrust outside the Room.
After the completion of maintenance, the second toeguard 108 need to be folded.Overhauling elevator is run to close to bottom position first, is operated
Personnel enter pit, and first connecting rod 105 and second connecting rod 106 are pushed from the back side of the first toeguard 107 and the second toeguard 108
Junction, release the self-locking state of foldable toeguard.Second toeguard 108 is rotated around main hinge 109, until the second spats
The plane residing for the first toeguard 107 of plane residing for plate 108.Finally, it inserts a key into triangulation chain 201 and rotates, locking bar
It 202 and the latch hook 203 that is fixed on locking bar 202 while rotating, up to latch hook 203 hooks into lock tube 204, by the second toeguard 108
It locks.After second toeguard 108 folds completely, the feeler lever device 206 being located on the second toeguard 108 triggers the first toeguard
Limit switch 205 on 107, limit switch 205 are closed, the signal transmission that the second toeguard 108 folds to control circuit, elevator
Into normal operating condition.
Embodiment 2
It is another embodiment of the utility model, the difference of the present embodiment and embodiment 1 with reference to shown in Fig. 7 and Fig. 8
It is, the air spring 110 in embodiment 1 is replaced with into compressed spring, which includes screw rod 301 and spring 302, is risen
To effect identical with air spring 110.When elevator needs maintenance, triangulation chain 201 is rotated, the second toeguard 108 is compressing
It is fully deployed under the driving of spring.Meanwhile compressed spring can reinforce stability of the foldable toeguard when elevator is run, and prevent
Foldable toeguard shakes, and reduces noise.
Only just best embodiment has done detailed description above, but should not be understood as implementing the utility model other
The limitation of mode, it is every on the basis of the utility model further improve and similar or identical scheme, be accordingly to be regarded as being this reality
With novel claimed range.
