[0002] Construction refers to the production activities in the implementation stage of project construction, which is the construction process of various buildings. It can also be said to be the process of turning the various lines on the design drawings into physical objects at the designated location. It includes foundation engineering construction, main structure construction, roofing engineering construction, decoration engineering construction, etc. The place where construction operations are carried out is called "construction site" or "construction site", also called a construction site. When carrying out civil engineering construction, steel bars are essential materials. Before use, steel bars are generally in a vertical state. Depending on the usage, the steel bars often need to be bent and cut. Therefore, a steel bar processing device is required.

[0003] The existing steel bar processing devices are used to bend and cut steel bars. Due to the different sizes of steel bars, when bending steel bars, it is necessary to manually press the steel bars for processing, which will consume a large amount of manual labor. Therefore, the technicians in this field have proposed a steel bar processing device at a construction site to solve the above problems. Content of the Utility Model

Due to the different sizes of steel bars, when bending steel bars, it is necessary to manually press the steel bars for processing, which will consume a large amount of manual labor.

[0005] To achieve the above object, the utility model provides the following technical solution: A steel bar processing device at a construction site includes a guiding table. The bottom of the guiding table is fixedly connected with a bottom plate. A hydraulic cylinder is installed at the bottom of the bottom plate.

One end of the rotating rod is fixedly connected with a connecting rod. One end of the connecting rod is fixedly connected with a clamping block. A guiding component is arranged outside the guiding table, and the guiding component can automatically push the steel bar into the bending device.

[0006] Further, the guiding component includes a lead screw. The lead screw is rotatably connected inside the guiding table. A threaded block is threadedly connected to the outside of the lead screw. A rotating column is rotatably connected to the top of the threaded block. A second guiding wheel is fixedly connected to the top of the rotating column.

[0022] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0023] Refer to Figures 1 - 3 , an embodiment provided by the present invention: A steel bar processing device at a construction site includes a guide table 1. A bottom plate 2 is fixedly connected to the bottom of the guide table 1. A hydraulic cylinder 3 is installed at the bottom of the bottom plate 2. The output end of the hydraulic cylinder 3 is fixedly connected to a rack plate 4. An installation box 5 is fixedly connected to the top of the bottom plate 2. A rotating rod 6 is rotatably connected inside the installation box 5. A cylindrical gear 7 is fixedly connected to the outside of the rotating rod 6. One end of the rotating rod 6 is fixedly connected to a connecting rod 8. One end of the connecting rod 8 is fixedly connected to a clamping block 9. A guiding assembly is arranged outside the guide table 1. The guiding assembly can automatically push the steel bar into the bending device. When one end of the steel bar enters the bending area, the hydraulic cylinder 3 is started to pull the rack plate 4 downward, so that the two cylindrical gears 7 rotate, and then the two rotating rods 6 rotate. In this way, the two connecting rods 8 rotate, and the two clamping blocks 9 can clamp the outside of the steel bar, thus replacing manual pressing by manpower, which is more convenient and labor-saving.

[0024] Refer to Figures 2 - 4, the guiding component includes a lead screw 13 which is rotatably connected inside the guiding platform 1. A threaded block 14 is threadedly connected to the outer side of the lead screw 13. A rotating column 16 is rotatably connected to the top of the threaded block 14. A second guiding wheel 17 is fixedly connected to the top of the rotating column 16. A cavity is formed inside the guiding platform 1. The outer side of the threaded block 14 is slidably connected to the inner wall of the cavity. One end of the lead screw 13 is fixedly connected to a crank 15. An assembly frame 10 is fixedly connected to the outer side of the guiding platform 1. A motor 11 is installed on the inner top wall of the assembly frame 10. The output end of the motor 11 is fixedly connected to a first guiding wheel 12. The outer side of the rack plate 4 is meshed with the outer side of the cylindrical gear 7. One side of the rack plate 4 is slidably connected to the inner wall of the installation box 5. Two cylindrical gears 7 are arranged inside the installation box 5. A guiding cylinder 18 is fixedly connected to the outer side of the guiding platform 1. Insert the steel bar into the guiding cylinder 18, and then push the steel bar to the middle position between the first guiding wheel 12 and the second guiding wheel 17. At this time, the crank 15 can be shaken to drive the rotation of the lead screw 13, so that the threaded block 14 slides, and the rotating column 16 drives the second guiding wheel 17 to press against the outer side of the steel bar. In this way, a large frictional force will be generated between the rubber layers on the outer circumferences of the first guiding wheel 12 and the second guiding wheel 17 and the steel bar. Starting the motor 11 can make the first guiding wheel 12 rotate, so that the steel bar can be pushed to move, and it can avoid spending manpower to push the steel bar into the working area.

[0025] Working principle: First, insert the steel bar into the guiding cylinder 18, and then push the steel bar to the middle position between the first guiding wheel 12 and the second guiding wheel 17. At this time, the crank 15 can be shaken to drive the rotation of the lead screw 13, so that the threaded block 14 slides, and the rotating column 16 drives the second guiding wheel 17 to press against the outer side of the steel bar. In this way, a large frictional force will be generated between the rubber layers on the outer circumferences of the first guiding wheel 12 and the second guiding wheel 17 and the steel bar. Starting the motor 11 can make the first guiding wheel 12 rotate, so that the steel bar can be pushed to move, and it can avoid spending manpower to push the steel bar into the working area. In addition, when one end of the steel bar enters the bending area, start the hydraulic cylinder 3 to pull the rack plate 4 to move downward, so that the two cylindrical gears 7 rotate, and then the two rotating rods 6 rotate, so that the two connecting rods 8 rotate, and the two clamping blocks 9 can clamp the outside of the steel bar, thus replacing manual pressing by manpower, which is more convenient and labor-saving.
