[0002] Construction projects refer to the construction of various buildings and structures, which are completed through construction activities. These include various buildings such as factories, warehouses, offices, residences, shops, schools, hospitals, clubs, cafeterias, and guesthouses. These projects include: the civil engineering of the buildings; the cost and installation of heating, sanitary, ventilation, lighting, gas, and other equipment, as included in the building project budget; and the laying of various pipelines (such as steam, compressed air, oil, and water supply and drainage), power cables, and telecommunications cables, as included in the construction project budget.

[0003] During the construction process of a building project, it is usually necessary to bend steel bars in order to assist in tying steel bars into cages. During the construction process of a building project, some different types of steel bars are stored for a long time, and rust and debris will form on the surface. As the bending proceeds, some debris may fly out. If it hits the skin or eyes of the workers, it will cause certain harm to the workers. The existing steel bar bending mechanism has no protective function, which causes certain inconveniences. Based on this, a steel bar bending mechanism for a building project is proposed. Utility Model Content

[0004] The purpose of the present invention is to provide a steel bar bending mechanism for construction engineering to solve the problems raised in the above-mentioned background technology.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a steel bar bending mechanism for construction engineering, comprising a box body, a protective frame hinged on one side of the top of the box body, a protective net fixedly installed on the top of the protective frame, a fan movably installed on the bottom of the protective net, two L-plates fixedly installed on the bottom of the protective frame, fixing bolts inserted inside the two L-plates, an inspection door movably installed on the front of the box body, four universal wheels movably installed on the bottom of the box body, a support bearing fixedly sleeved on the inside of the support bearing, a rotating shaft sleeved on the inside of the support bearing, a top turntable fixedly installed on the top of the rotating shaft, a support ring fixedly installed on the bottom of the top turntable, a fixing column fixedly installed on the top of the middle part of the top turntable, The outer side of the fixed column is movably connected with a support roller, and a plurality of adjustment holes are opened inside the top turntable, and the bottom of the adjusting hole is connected with an adjusting screw barrel, and the internal thread of the adjusting screw barrel is connected to the mounting column, and the outer side of the mounting column is movably connected with a bending roller, and the bottom of the rotating shaft is fixedly installed with a bottom turntable, and the bottom of the bottom turntable is fixedly installed with a support rod, and the inside of the box is fixedly installed with a first support column, and the outer side of the first support column is movably connected with a hydraulic telescopic column through a collar, and the outer side of the hydraulic telescopic column is movably connected with a movable sleeve, and the outer side of the movable sleeve is hinged with a hydraulic telescopic rod, and the end of the hydraulic telescopic rod away from the movable sleeve is movably connected with the second support column through a collar, and the bottom of the inner cavity of the box is fixedly installed with a hydraulic power device.

[0006] Preferably, the inner sides of the two L-plates are attached to the outer side of the box body, and the fixing bolts are threadedly connected through the L-plates and extend to the interior of the box body.

[0007] Preferably, the bottom of the support ring is in sliding contact with the top of the box.

[0009] Preferably, one end of the hydraulic telescopic column away from the first support column is movably sleeved on the outside of the support rod through a collar, and the second support column is fixedly installed on the top and bottom of the box body cavity.

[0010] Preferably, the output end of the hydraulic power device is connected to the input ends of the hydraulic telescopic column and the hydraulic telescopic rod through an oil pipeline.

[0011] Compared with the prior art, the beneficial effect of the present invention is that when the structure is in use, the position is first adjusted according to the thickness just performed through the adjusting hole and the mounting column, and then the steel bar to be bent is placed on the opposite side of (bending roller and support roller). When bending, the hydraulic telescopic column extends, thereby pushing the support rod, prompting the bottom turntable to rotate, and the bottom turntable applies force to the rotating shaft, which drives the top turntable to rotate through the rotating shaft, thereby driving the bending roller and the mounting column to rotate, and then bending the steel bar. When the bending angle of the steel bar exceeds degrees, the hydraulic telescopic column extends to the maximum extent. At this time, the hydraulic telescopic rod retracts at the maximum angle, prompting the position of the auxiliary hydraulic telescopic column and the support rod to change a certain angle. At this time, the retraction of the hydraulic telescopic column will drive the bottom turntable to continue to rotate through the support rod, thereby realizing a large-angle bending operation, which is convenient for performing different bending operations.

At the same time, the role of the universal wheel facilitates the operator to move, thereby increasing the overall convenience of use.

[0012] During the steel bar bending operation, when the steel bar is broken or cracked and splashes are generated, it is blocked by the protective frame, and the hollow setting of the protective net facilitates the observation of the operators and prevents objects from splashing. Combined with the blowing effect of the fan, the debris will not fly out through the protective net. In addition, the fan blows air on the bending part of the steel bar to cool the steel bar, reduce the heat generated by the steel bar due to bending, and thus affect the bending quality, which facilitates the operation.

The bottom of the adjustment hole 11 is connected to the adjustment screw barrel 25. The internal thread of the adjustment screw barrel 25 is connected to the mounting column 15. The outer side of the mounting column 15 is movably sleeved with a bending roller 14. The bottom of the rotating shaft 17 is fixedly mounted with a bottom turntable 18. The bottom of the bottom turntable 18 is fixedly mounted with a support rod 19. The inside of the box body 1 is fixedly mounted with a first pillar 20. The outer side of the first pillar 20 is movably sleeved with a hydraulic telescopic column 21 through a sleeve. The outer side of the hydraulic telescopic column 21 is movably sleeved with a movable sleeve 24. The outer side of the movable sleeve 24 is hinged with a hydraulic telescopic rod 22. The end of the hydraulic telescopic rod 22 away from the movable sleeve 24 is movably sleeved with a second pillar 23 through a sleeve. The bottom of the inner cavity of the box body 1 is fixedly mounted with a hydraulic power device 16.

[0021] The working principle of the above technical solution is as follows: when in use, first adjust the position according to the thickness just performed through the adjustment hole 11 and the mounting column 15, and then place the steel bar to be bent on the opposite side of the bending roller 14 and the support roller 10. When bending, the hydraulic telescopic column 21 extends, thereby pushing the support rod 19, prompting the bottom turntable 18 to rotate, and the bottom turntable 18 applies force to the rotating shaft 17, which drives the top turntable 8 to rotate through the rotating shaft 17, thereby driving the bending roller 14 and the mounting column 15 to rotate, and then bending the steel bar. When the bending angle of the steel bar exceeds 90 degrees, the hydraulic telescopic column 21 extends to the maximum.

Through the provided protective frame 4 and protective net 5, when the steel bar is bent, when the steel bar is fragmented or cracked to produce splashes, it is blocked by the protective frame 4, and the hollow setting of the protective net 5 facilitates the observation of the operators and blocks the splashing of objects. Combined with the blowing effect of the fan 13, the debris will not fly out through the protective net 5. In addition, the fan 13 blows air to the bending part of the steel bar to cool the steel bar, reduce the heat generated by the steel bar due to bending, and thus affect the bending quality, thereby facilitating the operation.

[0024] In another embodiment, Figure 1-Figure 5 As shown, the bottom of the support ring 12 is in sliding contact with the top of the box body 1.

[0025] The sliding of the support ring 12 facilitates providing certain support for the top turntable 8, thereby increasing the force on the bottom of the top turntable 8, making the overall use stable and increasing the structural strength.

In addition, the adjustment screw barrel 25 slides with the top of the box body 1, which is convenient for cooperating with the support ring 12 to provide support for the top turntable 8, thereby increasing the supporting force of the top turntable 8.

[0028] In another embodiment, Figure 3 and Figure 4 As shown, one end of the hydraulic telescopic column 21 away from the first support 20 is movably connected to the outside of the support rod 19 through a collar, and the second support 23 is fixedly installed at the top and bottom of the inner cavity of the box body 1.

[0029] The two ends of the hydraulic telescopic column 21 are respectively connected to the outside of the support rod 19 and the first pillar 20 through rings, which facilitates the coordinated operation of the hydraulic telescopic column 21 when extending and retracting to avoid locking.
