As shown in fig. 1 to 3, the reinforcing steel bar penetrating auxiliary machine for the precast beam comprises a penetrating machine body 1 and a lifting mechanism; the strand penetrating machine body 1 penetrates a certain reinforcing steel bar (or a plurality of reinforcing steel bars can be penetrated together) through an internal structure; after the insertion is finished, the position of the bundling machine body 1 is changed through the lifting mechanism, the bundling machine body is located at another position needing insertion, and then the next reinforcing steel bar is inserted.

During the insertion, the operation is divided into up-down operation and horizontal operation; firstly, inserting the glass tube at an initial position from bottom to top; then horizontally moving one position and penetrating from bottom to top.

The body of the bunching machine body 1 is formed by combining steel plates of a front wall, a rear wall, an upper wall and a lower wall, and is provided with a through cavity in the left-right direction. In this through cavity, an upper roller set 2 and a lower roller set 3 are provided, and a gap is provided between the upper roller set 2 and the lower roller set 3, and the gap is a stringing cavity. After the steel bars to be inserted are clamped by the upper roller set 2 and the lower roller set 3, the feeding of the steel bars is realized when the roller sets rotate, and therefore the insertion is realized.

In the scheme, the lower roller set 3 is active, and the central shaft of the lower roller set is connected with a driving mechanism; the upper roller set 2 is driven, and when the lower roller set 3 rotates, the rotation of the upper roller set 2 is realized simultaneously in the process of driving the steel bar feeding.

In this scheme, the design that is more central is, installs upper roller group 2 in wearing and restrainting machine organism 1 through elastic mechanism 5, and elastic mechanism 5 pushes down upper roller group 2 promptly to let upper roller group 2 press on upper roller group 3, elastically with the reinforcing bar centre gripping promptly.

The advantage of the design of the elastic mechanism 5 is that if the steel bars are long, for example, about 50m, the steel bars cannot be a whole, and a plurality of steel bars are welded to form a length of 50 m; therefore, there is a node (the diameter of the node is larger than the diameter of the steel bar itself) at the welding position, if the gap between the upper roller set 2 and the lower roller set 3 is fixed, the node cannot pass through, the elastic mechanism 5 can give way, and the gap is adjusted according to the size of the steel bar diameter.

The structural design of the elastic mechanism 5 is as follows:

the elastic mechanism 5 comprises a U-shaped long groove member 501 and a spring 502. The U-shaped long groove member 501 is arranged in an inverted manner (i.e. the long groove faces downwards), and is arranged along the through cavity in the left-right direction of the beam penetrating machine body 1; the upper roller set 2 is arranged in the elongated slot through a central shaft, and a bearing is arranged between the central shaft and the upper roller set 2; the top of the U-shaped long groove member 501 is provided with a post 503, the upper end of the post 503 passes through the upper wall of the strand threading machine body 1, and the threaded penetrating end is provided with an anti-falling nut 504.

That is, the U-shaped long groove member 501 is forced downward by the spring 502, so that the U-shaped long groove member 501 and the upper roller set 2 are moved downward together. When the position of the falling off prevention nut 504 is adjusted, the compression tightness of the U-shaped channel member 501 is adjusted.

In this embodiment, the upper roller set 2 and the lower roller set 3 are provided with anti-slip grooves 9 for anti-slip function.

In this embodiment, the number of the rollers of the upper roller group 2 is three, the middle roller is made of tendon material, and the outer roller is made of steel, so as to further play a role in skid resistance. The lower roller group 3 is four rollers on the same horizontal plane, and the rollers in the lower roller group 3 are opposite to the rollers in the upper roller group 2 in the gap position. That is, the upper and lower rollers do not clamp the reinforcing steel bars together at the same position, but clamp the reinforcing steel bars in a staggered mode, and therefore the stress points of the reinforcing steel bars are increased.

In order to operate the lower roller set 3 in the same direction:

the lower roller set 3 is fixedly connected with the central shaft thereof, the central shaft of the lower roller set 3 passes through the wall of the strand-threading machine body 1, and the lower roller set and the central shaft are installed in a matching way through a bearing; the extending end of the central shaft is provided with a gear A301, and a gear B is meshed between the two gears A301; in the lower roller group 3, a gear A301 of the middle roller is connected with a power motor 10 through a reduction box, and the gear A301 of the middle roller drives gears A301 of the other two rollers to rotate through gears B on two sides respectively; that is, all the gears a301 are rotated in the same direction.

The reinforcing steel bars with different heights can be inserted.

In this embodiment, the bottom of the stand 6 is provided with the universal wheel 602, so that the stand 6 can be moved to different steel structure positions. And a power motor 10 and a distribution box 4 powered by a lifting motor 7 are arranged on the vertical frame 6. A remote controller and a frequency converter are arranged in the distribution box 4, and the rotating speed is adjusted according to requirements.

In this embodiment, the machine body 1 is fixed on the bottom plate 11, and the bottom plate 11 is provided with a roller adapted to the chute of the stand 6.

In this embodiment, the stand 6 includes two parts, one part is used for placing the lifting motor 7 and the distribution box 4; the other part is inclined, and the inclined part realizes inclined lifting and is suitable for inserting box girders (a name of precast girders).

Of course, according to actual needs, the inclined part can be changed into a vertical lifting structure, and the structure is suitable for inserting T-shaped beams (which are also the name of precast beams).

That is, another part of the stand 6 is selectively adapted according to different beams.

After actual design and production, this auxiliary machine can once only wear one to many, and the diameter is 1~32mm, and length is the reinforcing bar of 50m once.
