Detailed Description

In order to make the technical problems, technical solutions and advantages to be solved by the present invention clearer, the following detailed description will be given with reference to the accompanying drawings and specific embodiments.

Referring to fig. 1 to 3, an embodiment of the present invention provides a multi-thread rebar pulling mechanism, which includes a frame 1, which mainly includes a top plate 2 and a plurality of side plates 3. The upper strata of every curb plate 3 is provided with a plurality of traction wheels 4 on side by side, and the lower floor is provided with a plurality of traction wheels 5 down side by side and with last traction wheel 4 one-to-one, and reinforcing bar 6 is pressed from both sides tightly between last traction wheel 4 and lower traction wheel 5, when the traction wheel rotates, pulls the reinforcing bar through frictional force and passes through between the two.

Every goes up traction wheel 4 and sets up respectively on pivot 7 on one, it sets up respectively in one rotates bearing 8 to go up pivot 7, every rotates bearing 8 all with a lifting cylinder 9's piston rod fixed connection, and can be at the vertical slip in the activity groove 10 that curb plate 3 was seted up, the last pivot 7 that the position corresponds on two adjacent curb plates 3 is connected through a universal shaft coupling 11, and the lower traction wheel 5 of same position sets up on the pivot 12 once jointly on all curb plates 3, pivot 12 supports through the fixed bearing 13 on the curb plate 3 down, the last pivot 7 of first curb plate 3 all overlaps with pivot 12 tip down and is equipped with meshed gear 14, and drive through a driving motor 15.

When the full thread of mechanism uses, every movable bearing 8 all is located the bottommost of activity groove 10, go up traction wheel 4 this moment and all hug closely and press from both sides reinforcing bar 6 with corresponding lower traction wheel 5, go up the gear 14 of the intermeshing of the 12 tip of last pivot 7 of first piece curb plate 3 and lower pivot and rotate under driving motor 15 drives step by step, and last pivot 7 on the first piece curb plate 3 passes through universal joint 11 and transmits to each last pivot 7 of connecting in proper order, make every go up pivot 7 and the last traction wheel 4 of cover establishing all rotate with lower pivot 12 and the lower traction wheel 5 synchronous of cover establishing, multithread, pull reinforcing bar 6 removal synchronously.

When the steel bar 6 of a certain thread needs to be stopped being pulled due to the conditions of insufficient feeding or slow beat of adjacent working procedures, failure and the like, the piston rod of the lifting cylinder 9 is contracted to lift all the movable bearings 8 of the thread, so that all the upper traction wheels 4 of the thread leave the corresponding lower traction wheels 5, at the moment, the steel bar 6 is only placed on the lower traction wheels 5 but not in a clamped state, and the steel bar 6 is not pulled to move only through the rotation of the lower traction wheels 5. Because the rotating bearing 8 of the thread is lifted, the upper rotating shaft 7 and the upper rotating shafts 7 of other threads are not positioned on the same axis, continuous rotation can be realized under the condition that the connected upper rotating shafts 7 have included angles through the connection of the universal coupling 11, and the torque can be reliably transmitted, so that the disconnection of the thread does not influence the synchronous rotation of the upper traction wheels 4 of other threads to pull the steel bars 6. After the lifting cylinder 9 at the first side plate 3 lifts the rotating bearing 8, the gear 14 at the end of the upper rotating shaft 7 is not meshed with the gear 14 at the end of the lower rotating shaft 12, the upper rotating shaft 7 does not rotate any more and transmits torque, and the traction mechanism is in a state of integral halt. Therefore, the working state of each thread can be conveniently switched only by controlling the action of the lifting cylinder 9.

Further, a steel bar guide groove 16 is formed in each of the upper traction wheel 4 and the lower traction wheel 5. When in traction, the wheel rims of the upper traction wheel 4 and the lower traction wheel 5 are in contact, the upper and lower steel bar guide grooves 16 form a channel of the steel bar 6, and friction force is generated through extrusion contact to drive the steel bar 6 to move.

Further, lifting cylinder 9 all sets up the upper surface at roof 2, and lifting cylinder 9's piston rod passes the opening of roof 2, with moving bearing 8 fixed connection, when the pulling of a certain thread of needs disconnection, only needs to control the 9 piston rods of lifting cylinder of this thread and contracts, drives moving bearing 8, last pivot 7 and the lifting of going up traction wheel 4 of this thread, can break off the pulling to reinforcing bar 6.

Further, movable bearing 8 is square structure, and the shaping is fluted 17 respectively on movable bearing 8's both sides, and movable bearing 8 is in the curb plate 3 card at place and is gone into corresponding recess 17, when movable bearing 8 when the displacement of lifting cylinder 9 effect down, because direction, the limiting displacement of curb plate 3, movable bearing 8 will follow curb plate 3 the direction, vertical direction slides promptly, promotes the accuracy that movable bearing 8 removed, prevents to take place great dislocation and influences universal joint 11's connection.

Further, the gears 14 at the end parts of two adjacent lower rotating shafts 12 are meshed, all the lower rotating shafts 12 can be driven by one gear 14, and two adjacent lower rotating shafts 12 rotate reversely. The gear 14 at the end of the upper rotating shaft 7 is meshed with the gear 14 corresponding to the end of the lower rotating shaft 12, and the upper rotating shaft 7 is arranged at intervals of one lower rotating shaft 12, so that all the upper rotating shafts 7 rotate in the same direction. In addition, the lower traction wheel 5 is not arranged on the lower rotating shaft 12 which is arranged at the interval and does not rotate in the opposite direction and is not arranged corresponding to the upper rotating shaft 7, namely, the lower rotating shaft 12 at the interval is only used for installing the gear 14 and is driven by the gear 14. Of course, the lower shaft 12 in this position can also be removed, leaving only the portion of the end mounting gear 14.

Furthermore, the gear 14 at the end of one of the lower rotating shafts 12 is fixedly connected with a driven wheel 18, and the driven wheel 18 is connected with the driving motor 15 through a belt 19, so that the whole mechanism can complete the full-thread traction process only through a single driving motor 15, the increased space required by arranging a plurality of motors is reduced, and the cost is saved.

Further, the outer surface of the upper traction wheel 4 is arranged roughly, and the outer surface of the lower traction wheel 5 is arranged smoothly, so that when the upper traction wheel 4 and the lower traction wheel 5 clamp the steel bars 8, the steel bars 8 are mainly pulled to move by friction force generated by the pressing contact of the steel bars 8 and the surface of the upper traction wheel 4. When the thread is disconnected and the upper traction wheel 4 is far away from the lower traction wheel 5, the steel bars 8 are only placed on the lower traction wheel 5, and the lower traction wheel 5 with a smooth surface rotates and is not enough to pull the steel bars 6 to move, so that the purpose of stopping traction is achieved.

Preferably, the frame 1 of this embodiment sets up two blocks of curb plates 3, is double-thread reinforcing bar drive mechanism promptly, and equipment is small and exquisite compact, and occupation site space is few, has satisfied most processing production demands simultaneously. In addition, a shaft cover 20 may be provided at the other end portions of the upper and lower rotating

shafts

7 and 12 for sealing protection.

The foregoing is a preferred embodiment of the present invention, and it should be noted that, for those skilled in the art, a plurality of improvements and decorations can be made without departing from the principle of the present invention, and these improvements and decorations should also be regarded as the protection scope of the present invention.
