Drive shaft, is horizontally rotated by bearing and is installed in wheel carrier I, and the drive shaft front end is provided with change gear；
Drive shaft drive mechanism, is installed on hanger, and two drive shafts of driving synchronously rotate in same direction；And
Two guide rails, it is horizontally placed on the bridge of the nose left and right sides along bridge of the nose length direction respectively, and two change gears of homonymy roll peace
Loaded on guide rail.
Sprocket wheel that above-mentioned drive shaft drive mechanism includes being installed in drive shaft, the reductor that is installed on hanger and with
The motor of speed reducer drive connection, the output shaft of the reductor is connected by shaft coupling and a drive shaft, two chains
Wheel is connected by chain drive.
For tension chain, in addition to the wheel carrier II being installed on hanger, the upper end of wheel carrier II is rotatablely equipped with tensioning
Wheel, the tensioning wheel is by chain tension.
In order to improve guidance quality, in addition to the wheel shaft of hanger front and rear sides is vertically arranged to respectively and is rotatablely installed in wheel
Directive wheel on axle, the directive wheel is in contact with the outward flange of the bridge of the nose.
The beneficial effects of the invention are as follows：When mobile formwork front leg strut needs vertical shift, drive shaft drive mechanism drives one
Two drive shafts on hanger synchronously rotate in same direction, so as to drive change gear to rotate, because bridge of the nose both sides are respectively provided with hanger, therefore two
Individual hanger is rotated by respective two change gears and walked along the guide rail on the bridge of the nose, is realized hanger and is hung front leg strut by bearing pin
Realize vertical shift, it is ensured that mean allocation front leg strut is conducted oneself with dignity, and prevents unbalance loading during front leg strut vertical shift.Connect by four change gears with guide rail
Touch, increase contact area, and then increase frictional force, prevent from skidding, it is ensured that the synchronism of both sides displacement.

Embodiment
Below in conjunction with the accompanying drawings 1, the present invention will be further described for accompanying drawing 2.
A kind of mobile formwork front leg strut running gear, including：Two hangers 2, respectively positioned at the left and right ends of the bridge of the nose 1, hanger 2
Lower end is hinged the top for being installed on front leg strut 4 by bearing pin 3, and each upper end of hanger 2 is provided with two wheel carriers I 6；Drive shaft 7,
Horizontally rotated by bearing and be installed in wheel carrier I 6, the front end of drive shaft 7 is provided with change gear 8；Drive shaft drive mechanism, is installed on
On hanger 2, two drive shafts of driving 7 are synchronous to be rotate in same direction；And two guide rails 5, it sets along the length direction level of the bridge of the nose 1 respectively
The left and right sides of the bridge of the nose 1 is placed in, two change gears 8 of homonymy, which are rolled, to be installed on guide rail 5.When mobile formwork front leg strut 4 needs vertical shift
When, drive shaft drive mechanism drives two drive shafts 7 on a hanger 2 are synchronous to rotate in same direction, so that drive change gear 8 to rotate,
Because the both sides of the bridge of the nose 1 are respectively provided with hanger 2, therefore two hangers 2 are rotated along the guide rail 5 on the bridge of the nose 1 by respective two change gears 8
Walking, realizes hanger 2 and hangs front leg strut 4 by bearing pin 3 and realize vertical shift, it is ensured that mean allocation front leg strut 4 is conducted oneself with dignity, before preventing
Occurs unbalance loading during 4 vertical shift of supporting leg.Contacted by four change gears 8 with guide rail 5, increase contact area, and then increase frictional force,
Prevent from skidding, it is ensured that the synchronism of both sides displacement.
It is preferred that, drive shaft drive mechanism is following structure, its sprocket wheel 9 for including being installed in drive shaft 7, is installed on extension
Reductor 10 on frame 2 and the motor 11 being connected with reductor 10, the output shaft of reductor 10 by shaft coupling 12 with
One drive shaft 7 is connected, and two sprocket wheels 9 are connected by chain 13.Motor 11 is rotated to slow down by reductor 10 and put
A drive shaft 7 is driven to rotate after high pulling torque, the drive shaft 7 drives sprocket wheel 9 thereon to rotate, so as to be driven separately by chain 13
One drive shaft 7 is rotated, and the synchronous same-speed for realizing two change gears 8 is rotated.
Further, in addition to the wheel carrier II 16 that is installed on hanger 2, the upper end of wheel carrier II 16 is rotatablely equipped with tensioning wheel
17, chain 13 is tensioned by tensioning wheel 17.Chain 13 is tensioned by tensioning wheel 17, can effectively be prevented in the accessary sprocket wheel 9 of chain 13
Come off, further increase the reliability used.
