Detailed description of the invention
As shown in Figure 1, 2, the layer door opening protecting apparatus of modified node method of the present invention, includes a layer door limiting parts 1, layer door drive element 2 and gate drive element 3.
Above-mentioned layer door limiting parts 1 include swing lock dog 11 and the locating part 12 with swing lock dog clamping interference fit.The path of motion plane of described swing lock dog 11 and plane-parallel (or forming acute angle), it is vertically installed in a layer Connection Block for every boatswain chair 41 13 is flexibly connected with one, there is hook lock swing arm 111 along swing axle center to extended outside two and drive swing arm 112, the tail end of hook lock swing arm 111 is provided with the grab 1111 with locating part 12 clamping interference fit, grab 1111 outer is smooth surface, middle part is connected with Connection Block 13 by the first retracing spring 113 and coordinates, and drives the tail end of swing arm 112 to be provided with roller 1121.Described locating part 12 is fixedly connected with layer door guide rail bracket 42 and vertically downward.
Above-mentioned layer door drive element 2 includes drive spindle 21, handle 22 and turning block 23, wherein, the upper end of drive spindle 21 is connected with swing lock dog 11 oblique, lower end and turning block 23 are rigidly connected, middle part is connected with layer door-plate 43 by the second retracing spring 24 and coordinates, upper end and the turning block 23 of handle 22 are rigidly connected, and turning block 23 is flexibly connected with layer door-plate 43 by a connection piece again, and drive spindle 21, turning block 23 and handle 22 form an activation lever structure.
Above-mentioned gate drive element 3 is provided with a driving be fixedly connected with car door rail frame and re-packs, and this driving re-packs and to contact with the driving swing arm 112 batch (-type) contact of swing lock dog 11, and its cross section is trapezium structure.Further, the distance of grab 1111 when layer door closure state and between locating part 12 of described hook lock swing arm 111 is greater than the distance driving the roller 1121 of swing arm 112 and driving to re-pack between 3 limit ends.
Principle of work of the present invention is as described below:
1, leveling zone.As shown in Figure 3, when layer door is normally opened or staff opens from stop, swing lock dog 11 and layer every boatswain chair 41 synchronizing moving, before the grab of hook lock swing arm 111 contacts with locating part 12, swing arm 112 3 contacts that re-pack with driving are in advance driven to contact, make swing lock dog 11 around the skew of swing axis swing, ensure that layer door can smooth and easyly be opened; As shown in Figure 4, cross driving when driving the roller of swing arm 112 and re-pack after 3, swing lock dog 11 resets under the restoring force effect of the first retracing spring 113.
2, non-leveling zone.As shown in Figure 5, staff needs to open layer door from stop because of special operational, after swing lock dog 11 and layer every boatswain chair 41 synchronizing moving one segment distance, and hook lock swing arm grab 1111 and locating part 12 clamping of swing lock dog 11, layer door breakdown action is stopped, and layer door cannot continue to open; As shown in Figure 2, if desired continue to open layer door, move handle 22 by layer crack between a door and its frame gap, handle 22 drives drive spindle 21 to tilt by turning block 23, and then drives the hook lock swing arm grab of swing lock dog 11 to depart from locating part 12, layer door can continue to open, after crossing locating part 12 Deng the grab of swing lock dog 11, release handle 22, under the second retracing spring 24 restoring force effect, drive spindle 21 resets, and drives swing lock dog 11 to reset.
3, layer door resets.As shown in Figure 6, when layer door is closed, first the grab 1111 of hook lock swing arm 111 contacts with locating part 12 contact, because grab 1111 outer is smooth surface, under the effect of self-closing power of closing the door, hook lock swing arm 111 can be backed down for limited 12, makes grab 111 cross locating part 12, thus layer door can continue to close reset.
The present invention is not limited to above-mentioned embodiment, if not departing from the present invention to various change of the present invention or modification is spirit and scope, if these are changed and modification belongs within claim of the present invention and equivalent technologies scope, then the present invention is also intended to comprise these change and modification.
