Abstract

The utility model relates to an automatic collision connection mechanism for mechanized bridge, whose third and fourth joints are respectively arranged on two bridge sects. The end surface of the fourth joint is arc face. The third joint comprises a pair of third head hooks which can rotate around a pin shaft. A pair of third head hooks present open state by the function of an extension spring which is arranged between the crosswise of the middle part of the tail of the third head hooks, before the two bridge sects aren't connected. When one bridge sect moves horizontally, the arc face of the fourth joint firstly collides the inner convex angle of the third head hook, and a pair of third head hooks are folded. A pin tongue can automatically rise up under the action of a pressure spring on a locking block, and the pin tongue can lock the third head pass through the tail hook of the pin tongue. When needing to disentangle, a detacher moves through a set of hinged joint device, making a lock-tongue quit the tail of the third head hook, and making the third head hook open automatically, and then achieving that the two bridge sects disentangle automatically.

Description

Automatic collision connection mechanism for bridge

A kind of mechanization bridge third fourth joint bindiny mechanism of collision automatically that relates to.

The present third fourth joint that adopted of pontoon bridge, realize installing in conjunction with the time, can only vertically insert, and this third fourth joint can only bear and transmit pulling force and pressure, can not bear shearing.

The purpose of this utility model is to provide a kind of two bridge sections that realize on horizontal plane from being dynamically connected and freeing, the third fourth joint bindiny mechanism that can bear pulling force, pressure and shearing.

The purpose of this utility model is achieved through the following technical solutions: it is to be made of the third joint D that is arranged on the fourth joint C on the bridge section A and be arranged on accordingly on the bridge section B for the automatic collision bindiny mechanism of this bridge; A fourth body 1 end face is an arcwall face, and its center is provided with the pin 21 that bears shearing, the third joint D on the bridge section B corresponding with it, and by third body 5, and a pair of third hook 2 and bearing pin 3 formations.5 liang of middle side parts of third body have lug 26 to embed respectively in the groove 25 at a pair of third hook 2 middle part, by corresponding pin-and-hole on lug 26 and third hook 2, with bearing pin 3 it is linked to each other, middle part, third body 5 termination is drilled with a hole 27 and 21 corresponding matching of preceding power pin, a pair of third hook 2 is provided with horizontal extension spring 22 near between the middle part of afterbody, and pass the slotted hole 28 at third body 5 middle part, with pin (4) extension spring 22 two ends are fixed; The below of the last third joint D of bridge section B is provided with bearing 10, be fixed with guide pillar 7 on this bearing, be with stage clip 9 on the guide pillar, lock dog 8 is contained on the guide pillar 7 slidably by the hole of itself, lock dog 8 fixing dead bolt 6 above it, when the third joint D locking, dead bolt 6 snaps in respectively in third corresponding breach 23 of hook 2 afterbodys, and the otic placode 20 at lock dog 8 bottom surfaces middle part is hinged and connected with drive link 11; Be fixed with two base plates 14 on the corresponding sidewall of bridge section B, axle 13 is housed on this base plate, be set with rotatable sleeve pipe 12 on this axle, its termination locks with nut, arm 17 and 18 before and after the horizontal direction both sides of sleeve pipe 12 are provided with, contact wheel 15 is equipped with in forearm 17 terminations, and this is taken turns and can roll along detacher 16, postbrachium 18 is hinged and connected with drive link 11, thereby constitutes whole automatic collision bindiny mechanism.

The utility model is compared the effect that is had with background technology:

1, correspondence is provided with this third fourth joint on the two bridge sections, makes on the two bridge Duan Zaiyi horizontal plane when connecting relatively, can realize colliding automatically locking and connect, and to free also is automatic.

2, this hits bindiny mechanism automatically, can either bear pulling force and pressure, can bear shearing again.

Below by accompanying drawing concrete technical application scheme of the present utility model is elaborated further.

The corresponding bindiny mechanism third fourth joint is in the axle survey schematic diagram of the state of freeing on Fig. 1, the two bridge sections;

The axis of no-feathering of Fig. 2, third hook and third body is surveyed schematic diagram;

The corresponding bindiny mechanism third fourth joint is in the axle survey schematic diagram of connection status on Fig. 3, the two bridge sections.

With reference to Fig. 1 and 2, the third joint D on fourth joint C on the bridge section A and bridge section B is in disconnected state accordingly at same horizontal plane, bridge section A and bridge section B need when being connected, bridge section B is moved with respect to bridge section A, the interior salient angle 24 that the cambered surface of the last fourth body 1 of bridge section A is at first collided a pair of third hook 2 of the last third joint D of bridge section B, along with the continuation of bridge section B is moved, a pair of third hook 2 just its bearing pin 3 separately of phase opposing connection inwardly rotates, meanwhile fourth joint C cambered surface center bears shearing pin 21, just enter in the corresponding hole 27, middle part, third body 5 termination on the bridge section B thereupon, contact wheel 15 on the forearm 17 of bridge section B breaks away from detachers 16, and the interior salient angle 24 of third joint of the bridge of the collision of the fourth joint C cambered surface on the bridge section A at this moment section B makes a pair of third hook 2 around separately bearing pin 3 rotations and make the third fourth joint become to be in fully blocking.At this moment, lock dog 8 rises at the effect lower edge of stage clip 9 guide pillar 7, thereby the dead bolt 6 that is fixed on above the lock dog 8 is just snapped in respectively in the breach 23 of corresponding a pair of third hook 2 afterbody, make the connection of the third fourth joint obtain locking, just bridge section A reaches with bridge section B and combines.

With reference to Fig. 3, if bridge section A and bridge section B are freed, its process is just in time opposite with above-mentioned two bridge sections combination, move the bridge section that connects, its contact wheel 15 is moved on the detacher 16, driving forearm 17 rises, postbrachium 18 just descends with the sleeve pipe 12 of rotation, therefore just driving drive link 11 moves downward, lock dog 8 descends thereupon, and compression press spring 9, and dead bolt 6 also withdraws from the breach 23 of a pair of third hook 2 near afterbody thereupon, at this moment set horizontal extension spring 22 between the middle part of a pair of third hook 2 afterbody, and the slotted hole 28 that passes third body 5 middle part inwardly draws the afterbody of a pair of third hook 2, makes a pair of third hook 2 just around separately bearing pin 3 rotations and open, and a pair of third hook 2 afterbody are drawn close relatively, at this moment dead bolt 6 is under a pair of third hook 2 afterbody the side respectively, and reaches bridge section A and bridge section B frees automatically.
