Description

Technical Field

[0001] The present invention relates to the field of construction site handling technology, and in particular to an automatic handling robot applied to a smart construction site. Background Art

[0002] A construction site is also called a construction site. Construction steel bars refer to various steel bars, steel wires, etc. used in reinforced concrete. During the construction process, the construction steel bars on the construction site need to be transported. At present, when transporting construction steel bars on construction sites, one end of the steel bar is generally fixed on a carrier and dragged. However, at this time, the other end of the steel bar is dragged on the ground, and drag marks will appear on the ground, thereby damaging the ground. Alternatively, a sling composed of a bracket and a lever is used. The middle part of the lever is hinged to the bracket, and wheels are installed at the bottom of the bracket. Hooks connected by steel wire ropes are hung at both ends of the lever to lift the steel bars.

[0003] When using the above-mentioned lifting device, due to the limited length of the lifting device lever, when transporting longer steel bars, the hooks at both ends of the lever will bend downward under the action of their own weight when lifting the steel bars. In addition, during the transportation process, due to the uneven ground of the construction site, the two ends of the steel bars will swing up and down, affecting the transportation of the steel bars. Workers need to hold the steel bars to prevent them from shaking when pushing the lifting device for transportation, so there are certain safety hazards.

[0004] Therefore, the present invention provides an automatic transport robot applied to a smart construction site to solve the above problems. Summary of the invention

Middle-section clamp slide rails 5 are fixedly installed, and middle-section clamp sliders 6 are installed in the two middle-section clamp slide rails 5 for sliding left and right. A steel bar middle-section clamp 7 that can be extended and retracted up and down is installed at the bottom of each middle-section clamp slider 6. The two steel bar middle-section clamps 7 can clamp the middle section of the steel bar and lift it upward. The two steel bar middle-section clamps 7 can move left and right on the middle-section clamp slide rails 5 respectively, so as to adjust their positions according to the length of the steel bar. After the position is adjusted, the steel bar middle-section clamp 7 extends downward to clamp the steel bar and lift the steel bar upward, and the base 1 can drive the steel bar to move;

[0039] The left and right ends of the carrying lever 4 are axially slidably mounted with a carrying extension lever 8, and the end of each carrying extension lever 8 away from the carrying lever 4 is connected to a steel bar end clamp 9 extending outward, and the steel bar end clamp 9 can clamp the two ends of the steel bar and lift the two ends of the steel bar upward to prevent it from bending downward.

When it continues to move downward, the compression cylinder 23 can be squeezed upward. After the two middle section clamps 18 are closed, the pressing arc rod 24 can realize the pressing limit of the top of the steel bar to prevent the steel bar from shaking during the movement.

[0049] Two rope shaft plates symmetrically positioned front and back are fixedly installed on the top of the base 1, and a steel traction rope shaft 25 is rotatably installed between the two rope shaft plates. Two traction support wheels 26 arranged up and down are rotatably installed on the top of the two ends of the two transport extension levers 8 away from the transport lever 4. Two end traction ropes 27 are wrapped around the outer side of the steel traction rope shaft 25. The free end of each end traction rope 27 passes through between the two traction support wheels 26 on one of the transport extension levers 8 and is connected to the steel end clamp 9. The steel traction rope shaft 25 is coaxially fixedly connected with an end traction worm gear 28.
