Description
Technical field
The relevant a kind of elevator safety touch panel device of the utility model is meant a kind of safe elevator safety touch panel device simple in structure, reliable especially.
Background technology
The safety edge device is the safety device of elevator cage door, guarantees elevator cage door in the switching process, turnover passenger's safety.Safety edge has two states, the one, the state of outstanding door edge, when gate in the complete opening and the process of opening the door, close the door, the turnover passenger ran into safety edge earlier before running into an edge; The 2nd, the state of withdrawal door edge inboard when gate is closed or closed soon, prevents the collision of left and right sides safety edge.
As shown in Figure 1, at present elevator safety touch panel device is formed by safety edge 1 and as the boxed rod mechanism and the lower link mechanism of auxiliary mechanism, this boxed rod mechanism comprises boxed rod 2, substrate 3 and upper spring 4, wherein, substrate 3 is fixed on the door-plate, and boxed rod 2 is hinged with safety edge 1 and substrate 3 respectively; Lower link mechanism comprises substrate 13, first lower link 6, second lower link 8, the 3rd lower link 10, the 4th lower link 17, the 5th lower link 18, the 6th lower link 19, lower spring 14 and travel switch 15, wherein hinged between first lower link 6 and second lower link 8 by jointed shaft 7, the 6th lower link 19 is hinged by jointed shaft 11 and substrate 13, jointed shaft 7 is fixing with substrate 13 respectively with jointed shaft 11, and be installed with helical torsional spring 16 on the jointed shaft 7, hinged between second lower link 8 and the 3rd lower link 10 by jointed shaft 9, relatively move between jointed shaft 9 and the substrate 13, travel switch 15 is fixed on the 3rd lower link 10.
Give prominence under the door edge state when safety edge 1 is in, upper spring 4 bears pulling force, lower spring 14 bears pulling force, travel switch 15 closures.When running into obstacles such as people when safety edge 1, safety edge 1 overcomes spring tension and withdrawal, collision block on first lower link 6 breaks away from travel switch 15 under leverage simultaneously, and travel switch 15 sends the switch cut-off signal, and door machine drive system is moved to the direction of door unlatching after receiving this signal; When gate is closed (about 2 ~ 3cm) time from off position soon, cam portion 12 on the 6th lower link 19 can be around jointed shaft 11 left-hand revolutions, by the helical torsional spring 16 on second lower link 8 and the jointed shaft 7, make first lower link 6 around jointed shaft 7 left-hand revolutions, thereby safety edge 1 is in time withdrawn, avoid mutual collision.But elevator safety touch panel apparatus structure complexity of the prior art, the cost of manufacture height owing to adopt the theory of machines action, if can influence the safe operation of touch panel device during wherein a certain parts et out of order, causes the damage of passenger or door of elevator.
The utility model content
In view of this, main purpose of the present utility model is to provide a kind of safe elevator safety touch panel device simple in structure, reliable.
For achieving the above object, the utility model provides a kind of elevator safety touch panel device, and it includes safety edge, door machine travel switch, boxed rod mechanism and lower link mechanism, and described door machine travel switch is fixed on the door machine of gate; Described boxed rod mechanism has open contact, and described door machine travel switch has normally closed contact, and described open contact and described normally closed contact be electrically and be connected in series, and described boxed rod mechanism and described lower link mechanism are hinged with described safety edge respectively.
Described boxed rod mechanism includes V-arrangement connecting rod, first substrate, upper spring and boxed rod travel switch, wherein said first substrate is fixed on the described gate, and described V-arrangement connecting rod is hinged by the last jointed shaft and described first substrate that are fixed on described first substrate; Described lower link mechanism includes lower link, second substrate and lower spring, and wherein said second substrate is fixed on the described gate, and described lower link is hinged by the following jointed shaft and described second substrate that are fixed on described second substrate; Described boxed rod travel switch has described open contact, and described V-arrangement connecting rod and described safety edge are hinged, and described lower link and described safety edge are hinged.
The upper end of described V-arrangement connecting rod has cam, and described door machine travel switch has the cam that can collide mutually with the cam on the described V-arrangement connecting rod when gate moves.
The utility model elevator safety touch panel device by increasing a door machine travel switch, makes physical construction become simpler, has reduced manufacturing cost, is more convenient for installing, and makes elevator more safe and reliable when switch moves.
Description of drawings
Fig. 1 is the structural representation of known elevator safety touch panel device;
Fig. 2 is the structural representation of the utility model elevator safety touch panel device.
The specific embodiment
For ease of structure of the present utility model and the effect that reaches are had further understanding, the preferred embodiment that develops simultaneously of existing conjunction with figs. is described in detail as follows.
As shown in Figure 2, the utility model elevator safety touch panel device includes safety edge 1, door machine travel switch 20, boxed rod mechanism and lower link mechanism, and wherein door machine travel switch 20 is fixed on the door machine of gate 21; Boxed rod mechanism includes V-arrangement connecting rod 30, first substrate 31, upper spring 32, boxed rod travel switch 33, wherein first substrate 31 is fixed on the gate 21, V-arrangement connecting rod 30 is hinged by the last jointed shaft 34 and first substrate 31 that are fixed on first substrate 31, and V-arrangement connecting rod 30 is hinged with safety edge 1; Lower link mechanism includes lower link 40, second substrate 41 and lower spring 42, wherein, second substrate 41 is fixed on the gate, and lower link 40 is hinged by the following jointed shaft 43 and second substrate 41 that are fixed on second substrate 41, and lower link 40 is hinged with safety edge 1.
Give prominence under the door edge state when safety edge 1 is in, upper spring 32 bears pulling force, lower spring 42 bears pulling force, and boxed rod travel switch 33 disconnects.When running into obstacles such as people when safety edge 1, safety edge 1 overcomes spring tension and withdrawal, collision block on the V-arrangement connecting rod 30 collides boxed rod travel switch 33 under leverage simultaneously, the open contact of boxed rod travel switch 33 sends switch closure signals, and door machine drive system is moved to the direction of door unlatching after receiving this signal; When gate 21 is closed (about 2 ~ 3cm) time from off position soon, cam 300 on the V-arrangement connecting rod 30 is the cam 200 on the collision gate machine travel switch 20 at first, the normally closed contact of a machine travel switch 20 is disconnected, this normally closed contact is connected with the open contact of boxed rod travel switch 33, thereby make system not receive the signal of boxed rod travel switch 33, then safety edge 1 can continue withdrawal, closes fully up to gate 21.After safety edge 1 withdrawal, when gate 21 states change, safety edge 1 can be given prominence to the door edge once more under the effect of spring, when gate 21 when opening the door near the position, cam 300 on the V-arrangement connecting rod 30 is the cam 200 on the collision gate machine travel switch 20 at first, the normally closed contact of a machine travel switch 20 is disconnected, because of this normally closed contact is connected with the open contact of boxed rod travel switch 33, thereby make system not receive the signal of boxed rod travel switch 33, thereby guarantee that door opening width does not reduce, even gate 21 door opening widths continue to increase.
The utility model elevator safety touch panel device by increasing a door machine travel switch, makes physical construction become simpler, has reduced manufacturing cost, is more convenient for installing, and has improved the not too reliable and secure shortcoming of original device operation.
The above is preferred embodiment of the present utility model only, is not to be used to limit protection domain of the present utility model.
