First horizontal pole 30 promotes 36 fly leaf lower extremes of expansion plate and moves left and accomplish after pushing away the transport to the left of reinforcing bar section, because the reinforcing bar section of below is simultaneously in the rebound, expansion plate 36 needs to reset fast and carries out the promotion of next reinforcing bar section, because the elasticity of elasticity telescopic link 64, elasticity telescopic link 64 can be fast with expansion plate 36 pull back and reset, the reliability of device has been improved, reinforcing bar section card of below is died when effectively having prevented expansion plate 36 to reset, the reliability of device has been improved.

Furthermore, as shown in the drawings, a plurality of spherical grooves 65 are uniformly formed on the upper side wall of the second inclined plate 32, and spheres 66 are connected in the spherical grooves 65 in a rolling manner, and the spheres 66 are always in contact with the lower side surface of the first inclined plate 27. Several spherical recess 65 has been seted up to the side of going up of second swash plate 32, the roll is connected with spheroid 66 in the spherical recess 65, when electric telescopic handle drives first swash plate 27 and upwards removes, the cooperation of spherical recess 65 and spheroid 66 makes the motion between first swash plate 27 and the second swash plate 32 become to slide for rolling, second swash plate 32 can slide left rapidly, drive first horizontal pole 30 and promote expansion plate 36, accomplish the left reinforcing bar of expansion plate 36 and carry, the reseing of expansion plate 36 also becomes easy simultaneously.

Furthermore, as shown in the figure, the baffle plates 67 are symmetrically arranged in front and back of the conveying device near the upper end of the conveying device. Swash plate 50 is close to the equal front and back symmetry of upper end position and installs baffle 67, and baffle 67 can prevent to be promoted to fall to the reinforcing bar section on the conveyer belt 59 from the side roll fall downstairs, injures constructor by a crashing object, can guarantee that all reinforcing bar sections are transported to the floor top, safe and reliable.

Furthermore, as shown in the drawings, the sheave 21 of the present embodiment has an annular elastic block 55 fixedly connected to the sheave surface. The wheel surfaces of the grooved wheels 21 are provided with the elastic blocks 55, and the elasticity of the elastic blocks 55 enables the grooved wheels 21 to clamp the steel bars better and more tightly, so that the steel bars can stably and firmly move upwards under the clamping of the grooved wheels 21, and the reliability of the device is improved.

Finally, it should be noted that: the above examples are only intended to illustrate the technical solution of the present invention, but not to limit it; although the present invention has been described in detail with reference to the foregoing embodiments, it will be understood by those of ordinary skill in the art that: the technical solutions described in the foregoing embodiments may still be modified, or some technical features may be equivalently replaced; and such modifications or substitutions do not depart from the spirit and scope of the corresponding technical solutions of the embodiments of the present invention.
