The central mechanism includes a third housing slidably disposed in the middle of the second housing, with a tail mechanism slidably disposed in the middle of the third housing. A clamping mechanism for fixing the device is fixed to the middle of the first housing. This device has a wide detection range, requires minimal manual operation to complete the inspection, and improves inspection efficiency.

[0004] The existing technology has the following problems:

[0005] In actual use, the bottom structure of the above-mentioned equipment comes into contact with the ground through the wheels. When workers are working on the platform surface, they inevitably need to walk around, which causes the equipment to shake. Since it is a high-altitude operation, the shaking will cause the bottom structure to shake, thus creating a safety hazard. Utility Model Content

[0006] This utility model provides a quality testing device for building frame beams to solve the problems mentioned in the background art.

[0007] In order to solve the above technical problems, the technical solution adopted by the present invention is:

[0008] A quality inspection device for building frame beams includes a box body, with wheels rotatably connected to the front and back of the box body near the left and right sides. A lifting mechanism is fixedly connected to the lower inner surface of the box body, and a protective mechanism is rotatably connected to the top of the lifting mechanism near the right side.

[0009] The lifting mechanism includes a servo motor. The lower surface of the servo motor is fixedly connected to the middle of the inner side of the housing. The output end of the servo motor is fixedly connected to a first threaded rod, and the left end of the first threaded rod is rotatably connected to the left side of the housing. The outer surface of the first threaded rod is threadedly connected to a folding frame, and the bottom right side of the folding frame is rotatably connected to the right side of the housing.

[0031] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0032] like Figures 1 to 4 As shown, a quality inspection device for building frame beams includes a box 1. Wheels 10 are rotatably connected to the front and back of the box 1 near the left and right sides. A lifting mechanism 2 is fixedly connected to the lower inner surface of the box 1. A protective mechanism 3 is rotatably connected to the top of the lifting mechanism 2 near the right side.

[0033] The lifting mechanism 2 includes a servo motor 20. The lower surface of the servo motor 20 is fixedly connected to the middle of the inner side of the housing 1. The output end of the servo motor 20 is fixedly connected to a first threaded rod 21, and the left end of the first threaded rod 21 is rotatably connected to the left side of the housing 1. The outer surface of the first threaded rod 21 is threadedly connected to a folding frame 22, and the bottom right side of the folding frame 22 is rotatably connected to the right side of the housing 1. The top of the folding frame 22 is slidably connected to a limit frame 23 near the left side.

[0034] The protective mechanism 3 includes a work platform 30. The lower surface of the work platform 30 is rotatably connected to the top of the folding frame 22 near the right side. The top of the limiting frame 23 is fixedly connected to the lower surface of the work platform 30 near the left side. Guardrails 31 are fixedly connected to the lower surface of the work platform 30 near both the front and rear. Handrails 32 are fixedly connected to the top of the guardrails 31.

[0035] After the worker enters the top of the work platform 30 through the openings on both sides, the servo motor 20 is powered on. The servo motor 20 drives the first threaded rod 21 to rotate. The rotation of the first threaded rod 21 causes the folding frame 22 to rotate and tilt, so that the right side of the top of the folding frame 22 slides within the limit frame 23, thereby causing the top work platform 30 to rise. This allows the work platform 30 to lift the worker to the work location. The guardrails 31 and handrails 32 around the work platform 30 can protect the area around the work platform 30, thus preventing the worker from falling off the top of the work platform 30.

[0036] like Figure 3 , Figure 5 and Figure 7 As shown, the handrail 32 has slots 33 on both sides near the left and right sides, and the top of the work platform 30 is rotatably connected to the ladder 34 near both sides.

[0037] When high-altitude operations are required, first rotate the escalator 34 to both sides of the box body 1, and then the staff can use the escalator 34 to enter the work platform 30.

[0038] like Figure 7and Figure 8 As shown, there are sliding blocks 35 on the top inner side of the escalator 34 near the front and back positions, and springs 36 are fixedly connected to the opposite side of the blocks 35.

[0039] When it is necessary to convert the escalator 34 into a protective structure, first rotate the escalator 34 to the top of the work platform 30, then push the locking block 35 into the escalator 34, align the locking block 35 with the locking slot 33 on the escalator 34, and then release the locking block 35. The spring 36 will drive the locking block 35 into the locking slot 33, thereby fixing the escalator 34.

[0040] like Figure 6 As shown, slide grooves 11 are provided on both the left and right sides of the housing 1 near the front and rear. Two threaded grooves 12 are provided on the inner side of the slide grooves 11 near the lifting mechanism 2.

[0041] The slider 43 can slide up and down according to the slide groove 11, and can be fixed by the threaded groove 12.

[0042] like Figure 2 , Figure 9 and Figure 10 As shown, a slider 43 is slidably connected to the inner side of the slide groove 11. A support rod 45 is rotatably connected to the side of the slider 43 away from the housing 1. A handwheel 44 is threadedly connected to the middle of the side of the slider 43 away from the housing 1.

[0043] When it is necessary to support and fix the box 1 around, first push the slider 43, so that the lifting and lowering of the slider 43 will cause the support rod 45 on one side to tilt. The tilting of the support rod 45 will cause the connecting rod 4 at the bottom to rotate, thereby unfolding the entire support structure. Then, by rotating the handwheel 44 into the threaded groove 12, the position of the slider 43 and the support rod 45 will be fixed.

[0044] like Figure 9 and 10 As shown, the bottom end of the support rod 45 is rotatably connected to the connecting rod 4, and the end of the connecting rod 4 near the lifting mechanism 2 is rotatably connected to the outer surface of the box 1. The lower surface of the connecting rod 4 away from the box 1 is fixedly connected to the threaded sleeve rod 40.

[0045] After the connecting rod 4 rotates to a horizontal position, it causes the threaded sleeve 40 at the bottom to become perpendicular to the ground.

[0046] like Figure 9 and Figure 10 As shown, the inner side of the threaded sleeve 40 is threadedly connected to a second threaded rod 41, and the bottom of the second threaded rod 41 is fixedly connected to a foot pad 42.

[0047] Then rotate the foot pad 42. The rotation of the foot pad 42 will drive the second threaded rod 41 at the top to rotate inside the threaded sleeve rod 40, thereby driving the foot pad 42 to descend. After the foot pad 42 contacts the ground, the foot pad 42, the second threaded rod 41, the threaded sleeve rod 40 and the connecting rod 4 will support and fix the box body 1 around its perimeter.

[0048] The working principle of this utility model is as follows: When it is necessary to inspect the quality of the roof beam frame, first rotate the escalator 34. After rotating the escalator 34 to one side of the box body 1, the staff enters the top of the work platform 30 through the escalator 34. Rotate the escalator 34 to make the locking block 35 lock into the locking slot 33, thereby fixing the escalator 34. At this time, the servo motor 20 drives the folding frame 22 to tilt, thereby driving the work platform 30 to rise. The rise of the work platform 30 drives the staff to rise and transport the staff to the work site to carry out the quality inspection of the roof beam frame.
