Background technology
In the prior art; Be in and be provided with the anti-door that floods in the subway station at river-crossing tunnel place; In order to prevent to cause river-crossing tunnel to break when the subway river-crossing tunnel generation burst accident; Cause river to leak into subway station and cause that accident enlarges, prevent flooding gate so all be provided with at subway station end and tunnel interface place that subway station is crossed section two ends, river.
The anti-Men Shangxu that floods of subway cooperates the anti-locking device that floods gate of installation, and its conventional locking device slides to the capable district of rail in order to prevent gate under off working state, and the spy is provided with locking device in the gate lower end, to guarantee the anti-safety of gate under off working state of flooding.Conventional locking device is that electric pushrod is done in order to apply power at the center line of locking beam, makes the locking beam be displaced to latched position forward and accomplishes lock out action.Because the track friction of locking beam lower end is inhomogeneous in this type of device, do not wait about the feasible easily displacement that produces, thereby cause the skew of locking beam, locking effect is bad, and the structure of this type of device is complicated, and maintenance is used inconvenient.
The utility model content
For addressing the above problem, the utility model provides a kind of anti-locking device that floods gate with more stable locking effect.
The utility model solves the technical scheme that its technical problem adopted:
A kind of anti-locking device that floods gate; Comprise cradling piece and be parallel to the locking beam of cradling piece; Be provided with parallel long connecting rod and short connecting rod between cradling piece and locking beam; The two ends of short connecting rod are hinged respectively to be installed on cradling piece and to lock on the beam, and an end of long connecting rod and the middle part of long connecting rod are articulated and connected with locking beam and cradling piece respectively, are provided with the telescopic shrinking connecting-rod of length between the other end of long connecting rod and the bottom of cradling piece.
Further as the improvement of the utility model technical scheme; The hinged bottom that is installed on cradling piece of shrinking connecting-rod; Be provided with the cottor pin that is used for hinged bearing pin and the said bearing pin of locking between the bottom of shrinking connecting-rod and cradling piece, the hinged place of shrinking connecting-rod and long connecting rod is equipped with can easy-to-dismount manual bolt.
Further as the improvement of the utility model technical scheme, cradling piece is the channel-section steel structure with the locking beam, and long connecting rod and short connecting rod are the flat steel bar structure.
Further as the improvement of the utility model technical scheme, other is provided with and can drives said shrinking connecting-rod and carry out the flexible motor of length.
Further as the improvement of the utility model technical scheme, the outside of motor is provided with the protective cover that is used to protect motor, and the surface of protective cover is provided with some heat elimination holes.
The beneficial effect of the utility model: this anti-locking device that floods gate constitutes the parallelogram transmission mechanism through each locking beam that is articulated and connected each other, cradling piece, long connecting rod and short connecting rod; And can drive the parallelogram transmission mechanism through the shrinking connecting-rod that between end of the long connecting rod that stretches out one jiao of parallelogram transmission mechanism and fixing cradling piece, is provided with flexible and carry out transmission; Thereby drive locking beam is parallel to fixing cradling piece always and in the plane at quadrangle transmission mechanism place, moves; And through release and the locking of flexible realization locking beam to preventing flooding gate of shrinking connecting-rod, this locking mechanism can reach more stable locking effect.
Description of drawings
Below in conjunction with accompanying drawing the utility model is described further:
Fig. 1 is that the utility model embodiment is in released state overall structure sketch map;
Fig. 2 is that the utility model embodiment is in the lock state the overall structure sketch map;
Fig. 3 is the utility model embodiment duty vertical view;
Fig. 4 is the utility model embodiment overall structure side schematic view.
The specific embodiment
With reference to Fig. 1～Fig. 4; The utility model is a kind of anti-locking device that floods gate; Comprise cradling piece 1 and be parallel to the locking beam 2 of cradling piece 1, cradling piece 1 and 2 on beam of locking are provided with parallel long connecting rod 3 and short connecting rod 4, and the two ends of short connecting rod 4 are hinged respectively to be installed on cradling piece 1 and the locking beam 2; One end of long connecting rod 3 and the middle part of long connecting rod 3 are articulated and connected with cradling piece 1 with locking beam 2 respectively, are provided with the telescopic shrinking connecting-rod 5 of length between the bottom of the other end of long connecting rod 3 and cradling piece 1.
This anti-locking device that floods gate constitutes the parallelogram transmission mechanism through each locking beam 2 that is articulated and connected each other, cradling piece 1, long connecting rod 3 and short connecting rod 4; And carry out transmission through driving the parallelogram transmission mechanism at the shrinking connecting-rod 5 of long connecting rod 3 one ends that stretch out in one jiao of parallelogram transmission mechanism and fixing 1 setting of cradling piece flexible; Thereby drive locking beam 2 is parallel to fixing cradling piece 1 always and in the plane at quadrangle transmission mechanism place, moves; And through 2 pairs of anti-release and lockings of flooding gate of flexible realization locking beam of shrinking connecting-rod 5, this locking mechanism can reach more stable locking effect.
As the utility model preferred embodiment; The shrinking connecting-rod 5 hinged bottoms that are installed on cradling piece 1; Be provided with the cottor pin that is used for hinged bearing pin and the said bearing pin of locking between the bottom of shrinking connecting-rod 5 and cradling piece 1, the hinged place of shrinking connecting-rod 5 and long connecting rod 3 is equipped with can easy-to-dismount manual bolt 6.
1 cottor pin through bearing pin lockable bearing pin of shrinking connecting-rod 5 and cradling piece is articulated and connected; Thereby stretching at shrinking connecting-rod 5 drives long connecting rod 3 around it during with the pin joint rotation of cradling piece 1, can make shrinking connecting-rod 5 also can rotate around the bearing pin of itself and cradling piece 1 junction.
