As shown in Figure 1 to Figure 3, a kind of bank bridge four trolley is disclosed in an embodiment of the present utility model, it comprises the first lateral bracket dolly 20, first sea, land lateral bracket dolly 10, second land and surveys trolley 30, second sea survey trolley 40, two cover tensioning hydro-cylinder 60 and two reels 50, and reel 50 is placed in machine house.Wherein, each reel 50 is provided with the first steel rope 51 and the second steel rope 52, survey trolley 30 with the first sea after first steel rope 51 is altered course by head assembly pulley 70 to be connected, second steel rope 52 is connected with the first land lateral bracket dolly 10 by afterbody assembly pulley 71 changed course, and each tensioning hydro-cylinder 60 connects with corresponding afterbody assembly pulley 71.
The first land lateral bracket dolly 10 is herein connected by the 3rd steel rope 53 with between the second land lateral bracket dolly 20.First sea is surveyed trolley 30 and is connected by the 4th steel rope 54 with the second extra large survey between trolley 40.Second land lateral bracket dolly 20 is surveyed between trolley 40 with the second sea and is connected by the 5th steel rope 55.
Further preferably, first extra large lateral bracket dolly 30 is provided with the first pulley assembling 72, one end of first steel rope 51 connects corresponding reel 50, the other end is fixed to head wire rope rope solid point place 80 through after head assembly pulley 70 and the first pulley assembling 72 successively, and head wire rope rope solid point 80 described here is positioned at the first sea and surveys on the object outside trolley 30.In like manner, first land lateral bracket dolly 10 is provided with the second pulley assembling 73, one end of second steel rope 52 connects corresponding reel 50, the other end is fixed to afterbody wire rope rope solid point 81 place through after afterbody assembly pulley 71 and the second pulley assembling 73 successively, and afterbody wire rope rope solid point 81 described here is positioned on the object outside the first land lateral bracket dolly 10.
In addition, a set of 3rd pulley assembling 74 is set respectively at the two ends of the first land lateral bracket dolly 10, one end of 3rd steel rope 53 is fixed to the first wire rope rope solid point place 82 be positioned on the second land lateral bracket dolly 20, the other end is fixed to the second wire rope rope solid point 83 place through after the 3rd pulley assembling 74, and the second wire rope rope solid point 83 described here is positioned on the object outside the second land lateral bracket dolly 20.
In like manner, the two ends surveying trolley 30 in the first sea arrange a set of 4th pulley assembling 75 respectively, one end of 4th steel rope 54 is fixed to the 3rd wire rope rope solid point 84 place be positioned on the second sea survey trolley 40, the other end is fixed to the 4th wire rope rope solid point 85 place through after the 4th pulley assembling 75, and the 4th wire rope rope solid point 85 described here is positioned on the object outside the second extra large lateral bracket dolly 40.
Further, survey in the second sea on trolley 40 and be also provided with two covers the 5th pulley assembling 76, one end of 5th steel rope 55 is fixed to the 5th wire rope rope solid point 86 place be positioned on the second land lateral bracket dolly 20, the other end is fixed to through after two cover the 5th pulley assemblings 76 the 6th wire rope rope solid point 87 place be positioned on the second land lateral bracket dolly 20.
The winding system of the utility model bank bridge four trolley described above is arranged symmetrically with relative to crossbeam line of centers.It utilizes duplex assembly pulley deceleration principle as shown in Figure 2, and the speed making the first sea survey trolley 30 is the half of the speed of the first steel rope 51.The speed of the first land lateral bracket dolly 10 is half of the speed of the second steel rope 52.Simply connected assembly pulley deceleration principle as shown in Figure 3, makes the speed of the first land lateral bracket dolly 10 be the half of the second land lateral bracket dolly 20.The speed that trolley 30 is surveyed in first sea is the half that trolley 40 is surveyed in the second sea.And the speed of the second land lateral bracket dolly 20 is equal with the speed that trolley 40 is surveyed in the second sea.
The object of the utility model bank bridge four trolley is the winding scheme providing a kind of novel bank abutment bracket, it holds up the lifting and winding of bank bridge at the trolley (four trolleys namely mentioned) that sea, side, land respectively adopt two speed not etc. herein, dolly is wound around and the lay winding wire ropes of self, shortened the span of steel rope by the quantity increasing trolley, thus reduction the outstanding of steel rope swings.Meanwhile, in bank bridge machine room, increase a set of independently drive system, make trolley that main carriage can not be needed to draw and independent operating.
The feature of the utility model bank bridge four trolley is:
One, be different from the winding form of general main carriage traction, this four trolley is wound around and carries independently drive system, makes trolley have more alerting ability in the adjustment of running velocity.Four trolleys as shown in drawings are wound around, and the first steel rope 51 be connected with the reel 50 of drive system and the speed of the second steel rope 52 just can directly be set by the drive motor rotating speed of reel 50.
Two, used pulley block ratio change to reach increasing, subtract the object of rope speed dexterously, made the rope speed of steel wire controlled, also just can run in an orderly manner between trolley and dolly.After setting the speed V of the first steel rope 51 and second steel rope 52 of drawing from drive system, other rope speed can be controlled by the change of pulley block ratio.As in the winding scheme in accompanying drawing, the speed of the extra large lateral bracket dolly 30 of the first land lateral bracket dolly 10, first is just reduced to 1/2V, the second extra large lateral bracket dolly 40 and the second land lateral bracket dolly 20 and the corresponding first sea are surveyed and are then realized speed by movable pulley between trolley 30, first land lateral bracket dolly 10 and be doubled to V.
Three, four trolleys are just wound around self steel rope number a lot, as there being 9 steel ropes in accompanying drawing altogether, add that there is the lifting and winding steel rope of bank bridge in outside, there is main carriage lay winding wire ropes inner side, it takes the modes such as space is longitudinal layered, horizontal stepping and arranges, to avoid mutually tangling between steel rope, interfering and hook.
In sum, more than the utility model bank bridge four trolley by reasonably arranging assembly pulley and steel rope, effectively controlling the speed of trolley, set up independently drive system, achieve the innovative design that bank bridge four trolley is wound around, meet application demand that is large-scale and even ultra-large type bank bridge.
Although the foregoing describe detailed description of the invention of the present utility model, it will be understood by those of skill in the art that these are only casehistorys, protection domain of the present utility model is defined by the appended claims.Those skilled in the art, under the prerequisite not deviating from principle of the present utility model and essence, can make various changes or modifications to these embodiments, but these change and amendment all falls into protection domain of the present utility model.
