Specific embodiment
The specific embodiment further illustrated the present invention below in conjunction with the accompanying drawings.
Embodiment 1
As shown in figures 1-4, a kind of foldable toe guard of elevator car, including be fixed on car platform the first toeguard 107,
With the first toeguard 107 by the second hinged toeguard 108 of main hinge 109, be fixed on the first fixed frame of car platform
101st, the second fixed frame 102 of the second toeguard 107 is fixed on, further includes linkage.
Wherein, linkage includes：The first base 103 that is connected on the first fixed frame 101 is articulated with first base
103 first connecting rod 105, the second base 104 being connected on the second fixed frame 102, the second company for being articulated with second base 104
Bar 106 and both ends are hingedly connected to the air spring 110 of 105 and first toeguard 107 of first connecting rod.The first connecting rod
105 and second connecting rod 106 connected by bearing 112,112 bearing can also be replaced with pin or hinge.The second connecting rod
106 are equipped with bending edges 111, the angle rotated between first connecting rod 105, second connecting rod 106 can be limited, so as to limit the first shield
107 and second toeguard 108 of sole is 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
202nd, latch hook 203 and lock tube 204 be at grade.In order to prevent locking bar 202 it is long and drop or fracture, the locking bar 202
It is connected by the hook 207 on the first fixed frame 101 with car platform, the hook 207 is used to trigger 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 invention and folding work process description are as follows：
When elevator needs maintenance, insert 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 by the signal transmission that the second toeguard 108 is unfolded 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 promoted 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
Plane residing for plate 108 is perpendicular to plane residing for the first toeguard 107.Finally, insert a key into triangulation chain 201 and rotate, locking bar
It 202 and the latch hook 203 that is fixed on locking bar 202 while rotates, 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 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 present invention with reference to shown in Fig. 7 and Fig. 8, the present embodiment and the difference of embodiment 1 exist
In, the air spring 110 in embodiment 1 is replaced with into compression spring, the compression spring include screw rod 301 and spring 302, play
The effect identical with air spring 110.When elevator needs maintenance, triangulation chain 201 is rotated, the second toeguard 108 is in compression bullet
It is fully deployed under the driving of spring.Meanwhile compression spring can strengthen stability of the foldable toeguard when elevator is run, preventing can
It folds toeguard to rock, reduces noise.
Only just optimal embodiment has done detailed description, but it is not intended that the other modes implemented to the present invention above
Limitation, it is every on the basis of the present invention it is further improvement and similar or identical scheme, be accordingly to be regarded as be the present invention request protect
The scope of shield.
