Description
Technical field
The present invention relates to a kind of steel bar girder lower edge muscle synchronous shear mechanism, specifically for the synchronous shear of lower edge muscle, belong to the steel truss technology field.
Background technology
The steel bar girder point is welded on base plate and forms steel bar truss floor support plate, is applied to industry and civil buildings and structures.When steel bar girder is used for concrete floor slab construction, it is layed on beam, to bear concrete gravity and construction loads.Simultaneously, steel bar girder is used as again the permanent framework of steel reinforcement of floor.
The steel bar truss welding machine production line is exactly the biscuit steel bar welding to be connected into to the welding equipment production line of steel bar girder.Steel bar girder mainly contains one, the muscle that winds up (straight muscle), two, lower edge muscle (straight muscle), and two compositions of web rib (waveform).Wind up and by resistance welded, be integral between muscle and web rib, lower edge muscle and web rib.Because five chargings are steel-bar, so will cut off after the steel bar truss welding certain-length, cut off reinforcing bar and cut off by hydraulic cylinder, while due to hydraulic cylinder, cutting off two cut off arms can not be simultaneously near the lower edge muscle, lower edge muscle cut off the phenomenon of therefore easily occur in cutting-off process.
Summary of the invention
The object of the invention is to overcome above-mentioned weak point, thereby provide a kind of steel bar girder lower edge muscle synchronous shear mechanism, can prevent effectively that the lower edge muscle from only being cut off one in cutting-off process, prevent that effectively the left and right sides shearing blade is due to the further stepping of steel bar girder that causes stoping not in place that resets simultaneously.
According to technical scheme provided by the invention, steel bar girder lower edge muscle synchronous shear mechanism comprises that top is provided with the installing rack of open slot, it is characterized in that: in open slot, be arranged with first and cut off arm and the second cut-out arm, first cuts off arm is rotationally connected installing rack by the first synchronous rotating shaft, and second cuts off arm is rotationally connected installing rack by the second synchronous rotating shaft.First cuts off the arm lower end by the first hydraulic cylinder rotating shaft connecting fluid cylinder pressure one end, and second cuts off the arm lower end by the second hydraulic cylinder rotating shaft connecting fluid cylinder pressure other end.Installing rack one end connects pressing plate, on pressing plate, is rotationally connected the first synchronous rotating shaft and the second synchronous rotating shaft.On the first synchronous rotating shaft, connect the first synchromesh gear, the first synchromesh gear is bolted on first and cuts off on arm.On the second synchronous rotating shaft, connect the second synchromesh gear, the second synchromesh gear is bolted on second and cuts off on arm.Installing rack center fixed blade piece, first cuts off the arm upper end connects the first shearing blade, and second cuts off the arm upper end connects the second shearing blade.
Further, open slot one side of installing rack is fixed the first front limit piece and the second front limit piece, limited block after opposite side is fixing.
Further, the other guide plate that is provided with of the first front limit piece and the second front limit piece.
Further, the first cut-out arm side is bolted the first slide plate.
Further, the second cut-out arm side is bolted the second slide plate.
Compared with the prior art the present invention has the following advantages:
The present invention is simple in structure, compact, reasonable, and when hydraulic cylinder piston rod stretched out, left and right cut-out arm respectively can be simultaneously close to the lower edge muscle by the engagement of a pair of identical gear around fulcrum separately, namely cuts off simultaneously reinforcing bar; When hydraulic cylinder piston rod was retracted, left and right cut-out arm can reset simultaneously around the engagement by a pair of identical gear of separately fulcrum respectively, can effectively guarantee passing through of steel bar girder.

The specific embodiment
Following the present invention is further described in connection with the embodiment in accompanying drawing:
As shown in Figure 1 and 2, the present invention comprises that mainly top is provided with the installing rack 1 of open slot, in open slot, be arranged with first and cut off arm 3 and the second cut-out arm 8, the first cut-out arm 3 is rotationally connected installing rack 1, the second cut-out arm 8 by the first synchronous rotating shaft 13 and is rotationally connected installing rack 1 by the second synchronous rotating shaft 16.First cuts off arm 3 lower ends by the first hydraulic cylinder rotating shaft 10 connecting fluid cylinder pressure 11 1 ends, and second cuts off arm 8 lower ends by second hydraulic cylinder rotating shaft 17 connecting fluid cylinder pressure 11 other ends.Installing rack 1 one ends connect pressing plate 14, on pressing plate 14, are rotationally connected the first synchronous rotating shaft 13 and the second synchronous rotating shaft 16.
On the first synchronous rotating shaft 13, connecting the first synchromesh gear 12, the first synchromesh gears 12 is bolted on the first cut-out arm 3.On the second synchronous rotating shaft 16, connecting the second synchromesh gear 15, the second synchromesh gears 15 is bolted on the second cut-out arm 8.
Open slot one side of installing rack 1 is fixed the first front limit piece 2 and the second front limit piece 9, limited block 5 after opposite side is fixing.The first front limit piece 2 and the other guide plate 18 that is provided with of the second front limit piece 9.Installing rack 1 center fixed blade piece 6.The first front limit piece 2 and the second front limit piece 9 prevent that first cuts off arm 3 and the second cut-out arm 8 deviation positions.
The first cut-out arm 3 sides are bolted the first slide plate 19, the second cut-out arm 8 sides and are bolted the second slide plate 20, and rear limited block 5 prevents that first cuts off arm 3 and the second cut-out arm 8 deviation positions.
First cuts off arm 3 upper ends connects first shearing blade 4, the second cut-out arm 8 upper ends connection the second shearing blades 7.
Operation principle of the present invention is: during work, the piston rod of hydraulic cylinder stretches out, and promotes the first cut-out arm 3 and second and cuts off arm 8 around the first synchronous rotating shaft 13 and the second synchronous rotating shaft 16 rotations.The first synchromesh gear 12 and the second synchromesh gear 15 synchronously rotate thereupon, and the first shearing blade 4 and the second shearing blade 7 relatively move with scissors piece 6, thereby cut off the lower edge muscle.The piston rod of hydraulic cylinder 12 is retracted, and the first cut-out arm 3 and second cuts off arm 8 and resets simultaneously around the first synchronous rotating shaft 13 and the second synchronous rotating shaft 16 rotations by the first synchromesh gear 12 and the second synchromesh gear 15.
