An embodiment of a steel structure detection device for construction engineering according to the present invention is shown in fig. 1 to 9.
A steel structure detection device for constructional engineering comprises a rotating shaft 100, a rotating drum 110, an adhesive tape 120 and a trigger piece. The rotating shaft 100 is disposed along a first direction, and the rotating shaft 100 can rotate around its own axis and can move along a second direction, wherein the first direction is a horizontal direction, and the second direction is a direction which is horizontal and perpendicular to the first direction. The rotary drum 110 is arranged along a first direction and sleeved on the rotary shaft 100, the adhesive tape 120 comprises a first pasting section 122, a connecting section 123 and a second pasting section 121, the first pasting section 122 is pasted on the surface of the steel structure 200 along a second direction, the second pasting section 121 is pasted on the rotary drum 110, the connecting section 123 is connected with the first pasting section 122 and the second pasting section 121, the rotary drum is in a suspended state, an included angle formed between the first pasting section 122 and the connecting section 123 in an initial state is larger than 60 degrees, the rotary shaft 100 and the connecting section 123 are sequentially arranged along the second direction, and the rotary drum 110 is located inside an area defined by the first pasting section 122, the connecting section 123 and the second pasting section 121.
The steel structure detection device for construction engineering has a first state and a second state, when in the first state, the rotating shaft 100 moves along the second direction to the side far away from the connecting section 123 and rotates around the axis of the rotating shaft, the rotating drum 110 rotates relative to the rotating shaft 100, the rotating direction of the rotating shaft 100 is opposite, the length of the first pasting section 122 is unchanged, the connecting section 123 is lengthened, and the second pasting section 121 is shortened; in the second state, the rotating shaft 100 moves along the second direction to the side far away from the connecting section 123 and rotates around the axis thereof, the rotating drum 110 rotates synchronously with the rotating shaft 100, the first pasting section 122 is shortened, the length of the connecting section 123 is unchanged, and the second pasting section 121 is lengthened. And in the first state, the included angle formed between the first pasting section 122 and the connecting section 123 is gradually reduced, and when the included angle formed between the first pasting section 122 and the connecting section 123 is 60 degrees, the trigger piece can be driven to act, the trigger piece can enable the steel structure detection device for construction engineering to switch from the first state to the second state, and the moving speed of the rotating shaft 100 along the second direction is the same as the rotating linear speed of the rotating drum 110.
In this embodiment, by setting the rotating shaft 100, the rotating drum 110, the adhesive tape 120 and the trigger piece, when the device is used, after the surface of the steel structure 200 is diced according to the process flow, the first pasting section 122 of the adhesive tape 120 is pasted on the surface of the steel structure 200, the second pasting section 121 of the adhesive tape 120 is pasted on the rotating drum 110, and at this time, since the first pasting section 122 is arranged along the second direction, the second pasting section 121 is arranged along the circumferential direction of the rotating shaft 100, therefore, after the first pasting section 122 is pasted on the surface of the steel structure 200, the connecting section 123 for connecting the first pasting section 122 and the second pasting section 121 is in a suspended state, and the included angle formed between the first pasting section 122 and the connecting section 123 is greater than 60 ° (because manual operation is required for pasting, the included angle formed between the first pasting section 122 and the connecting section 123 can be determined by naked eyes by greater than 60 ° for facilitating observation, so that the angle is more than 90 ° can be most obviously determined by naked eyes).
Then, the rotating shaft 100 is moved along the second direction to the side far away from the connecting section 123 and rotates around the axis of the rotating shaft 100, and the rotating direction of the rotating shaft 100 is the anticlockwise direction shown in fig. 8. At this time, in the first state of the steel structure detection device for construction engineering, since the rotating shaft 100 moves to the side far away from the connecting section 123 along the second direction, the rotating shaft 100 has a tendency of driving the first pasting section 122 to move synchronously through the rotating drum 110, tearing the first pasting section 122 apart from the steel structure 200 and winding the first pasting section 122, but due to the pasting force between the first pasting section 122 and the steel structure 200, a traction force is given to the rotating drum 110 in the circumferential direction thereof, so that the rotating drum 110 is driven to rotate in the opposite direction to the rotating shaft 100, namely, clockwise direction as shown in fig. 8. Therefore, the drum 110 cannot drive the first pasting section 122 to wind, the rotating shaft 100 and the drum 110 move relative to the first pasting section 122, the first pasting section 122 is not torn, the length is unchanged, the drum 110 reversely rotates relative to the rotating shaft 100, the length of the second pasting section 121 is shortened, when the total length of the adhesive tape 120 is unchanged, the length of the connecting section 123 is prolonged, and in the process that the rotating shaft 100 and the drum 110 move relative to the first pasting section 122, the included angle between the connecting section 123 and the first pasting section 122 is gradually reduced.
And when the included angle formed between the first pasting section 122 and the connecting section 123 is 60 degrees, the trigger piece is driven to act, the trigger piece acts to enable the steel structure detection device for construction engineering to be switched from the first state to the second state, when the steel structure detection device for construction engineering is in the second state, the rotating shaft 100 moves along the second direction to the side far away from the connecting section 123 and rotates around the axis of the steel structure detection device, at the moment, the rotating drum 110 and the rotating shaft 100 synchronously rotate, the first pasting section 122 of the adhesive tape 120 is wound, in the process, the first pasting section 122 is shortened, the length of the connecting section 123 is unchanged, and the second pasting section 121 is lengthened. And because the speed of the rotation shaft 100 moving along the second direction is the same as the linear speed of the rotation of the rotary drum 110, after the included angle formed between the first pasting section 122 and the connecting section 123 is 60 degrees, when the rotation shaft 100 and the rotary drum 110 synchronously rotate to wind the first pasting section 122, the included angle formed between the first pasting section 122 and the connecting section 123 is kept unchanged until the winding is completed, and the included angle is always 60 degrees.
According to the embodiment, the relative motion state of the rotary drum 110 and the rotary shaft 100 is changed, so that the included angle between the first pasting section 122 and the connecting section 123 is adjusted, and after the included angle formed between the first pasting section 122 and the connecting section 123 is 60 degrees, the included angle formed between the first pasting section 122 and the connecting section 123 is kept at 60 degrees and is straightened to be coiled, so that the detection accuracy is improved, and errors possibly caused by manual detection are avoided by limiting the moving speed of the rotary shaft 100 along the second direction to be the same as the rotating linear speed of the rotary drum 110.
In this embodiment, the steel structure detection device for construction engineering further includes a matching plate 130, where the matching plate 130 is of a magnetic structure and has elasticity, so that the matching plate 130 can be adsorbed on the surface of the steel structure 200. The matching plate 130 is provided with a rack 131, the rack 131 is arranged along the second direction, the rotating shaft 100 is fixedly provided with a gear 101, the gear 101 is coaxially arranged with the rotating shaft 100, the gear 101 is meshed with the rack 131 in an initial state, the rotating shaft 100 can be driven to rotate around the axis direction of the rotating shaft through the meshing of the gear 101 and the rack 131 in the process that the rotating shaft 100 moves along the second direction, and the diameter of the gear 101 is identical to that of the rotating drum 110.
By setting the diameter of the gear 101 to be the same as the diameter of the drum 110, the linear speed of the gear 101 and the drum 110 are the same, and since the gear 101 is fixedly mounted on the rotating shaft 100, the rotating shaft 100 can be driven to rotate, so that the angular speed of the rotating shaft 100 and the gear 101 is the same, and the speed of the rotating shaft 100 moving along the second direction is the same as the linear speed of the rotating shaft 101, that is, the same as the linear speed of the rotating drum 110. The arrangement is such that when the rotation shaft 100 rotates synchronously with the drum 110 to wind the first pasting section 122 after the angle formed between the first pasting section 122 and the connecting section 123 is 60 °, the angle formed between the first pasting section 122 and the connecting section 123 is kept unchanged until the winding is completed.
Specifically, the matching plate 130 is rectangular, the number of racks 131 is two, the two racks 131 are sequentially arranged on the matching plate 130 along the first direction, two gears 101 are fixedly arranged on the rotating shaft 100, and each gear 101 is meshed with one rack 131.

Specifically, a pull rod 141 is disposed on the rotating frame 140, supporting legs are disposed on the rotating frame 140, and rollers 142 are rotatably disposed on the supporting legs. When in use, an operator manually pulls the pull rod 141 to further pull the rotating frame 140 to move, so that the roller 142 rolls on the steel structure 200, and the rotating frame 140 can move to drive the rotating shaft 100 to move synchronously.

The applicability of the steel structure detection device for the building engineering is further improved.
By combining the above embodiments, the specific working principle and working process are as follows:
when in use, after the surface of the steel structure 200 is diced according to the process flow, the first pasting section 122 of the adhesive tape 120 is pasted on the surface of the steel structure 200, the second pasting section 121 of the adhesive tape 120 is pasted on the drum 110, and at this time, since the first pasting section 122 is arranged along the second direction and the second pasting section 121 is arranged along the circumferential direction of the rotating shaft 100, after the first pasting section 122 is pasted on the surface of the steel structure 200, the connecting section 123 for connecting the first pasting section 122 and the second pasting section 121 is in a suspended state, and the included angle formed between the first pasting section 122 and the connecting section 123 is larger than 60 ° (because manual operation is required for pasting, the included angle formed between the first pasting section 122 and the connecting section 123 after the pasting is completed can be larger than 60 ° by naked eyes, so that the angle is larger than 90 ° for facilitating observation and is the most obvious angle for naked eye judgment). With particular reference to fig. 8.
Then, the pull rod 141 is manually pulled, and the rotating frame 140 is pulled to move leftwards as shown in fig. 8, so that the roller 142 rolls on the steel structure 200, and the rotating frame 140 can drive the rotating shaft 100 to move synchronously. The movement of the rotating shaft 100 can cause the rotating shaft 100 to rotate around its own axis direction by engaging the gear 101 with the rack 131. The rotation direction of the rotation shaft 100 is counterclockwise as shown in fig. 8. At this time, in the first state of the steel structure detection device for construction engineering, since the rotating shaft 100 moves to the side far away from the connecting section 123 along the second direction, the rotating shaft 100 has a tendency of driving the first pasting section 122 to move synchronously through the rotating drum 110, tearing the first pasting section 122 apart from the steel structure 200 and winding the first pasting section 122, but due to the pasting force between the first pasting section 122 and the steel structure 200, a traction force is given to the rotating drum 110 in the circumferential direction thereof, so that the rotating drum 110 is driven to rotate in the opposite direction to the rotating shaft 100, namely, clockwise direction as shown in fig. 8. Therefore, the drum 110 cannot drive the first pasting section 122 to wind, the rotating shaft 100 and the drum 110 move relative to the first pasting section 122, the first pasting section 122 is not torn, the length is unchanged, the drum 110 reversely rotates relative to the rotating shaft 100, the length of the second pasting section 121 is shortened, when the total length of the adhesive tape 120 is unchanged, the length of the connecting section 123 is prolonged, and in the process that the rotating shaft 100 and the drum 110 move relative to the first pasting section 122, the included angle between the connecting section 123 and the first pasting section 122 is gradually reduced, so that the scraping plate 190 and the trigger plate 150 are mutually close, namely the connecting section 123 and the trigger plate 150 are mutually close.
And when the included angle formed between the first attaching section 122 and the connecting section 123 is 60 °, refer to fig. 9 specifically. The scraping plate 190 can be abutted against the connecting section 123 of the adhesive tape 120, the connecting section 123 of the adhesive tape 120 can apply a rotating force to the trigger plate 150 through the scraping plate 190 to the rotating shaft 100, so that the trigger plate 150 is driven to rotate, the trigger plate 150 rotates to drive the telescopic block 151 to synchronously rotate, and the telescopic block 151 can rotate to be in contact with the wedge block 181 (specifically, parameters such as an initial position of the trigger plate 150, gravity of the scraping plate 190, torsion of a torsion spring and the like can be set, and before use, the trigger ring 180 is rotated, and the position of the wedge block 181 in the circumferential direction of the rotating shaft 100 with the telescopic block 151 in an initial state is adjusted through rotating the trigger ring 180, so that when an included angle formed between the first pasting section 122 and the connecting section 123 is 60 degrees, the trigger plate 150 drives the telescopic block 151 to rotate, and the telescopic block 151 can be rotated to be in contact with the wedge block 181. The wedge block 181 will cause the telescopic block 151 to move in the first direction to the side close to the moving ring 160, and further cause the moving ring 160 to move in the first direction to the side close to the drum 110, increasing the positive pressure between the moving ring 160 and the drum 110, and switching the steel structure detection device for construction engineering from the first state to the second state. The rotating shaft 100 can drive the rotating drum 110 to synchronously rotate through friction, so that the first pasting section 122 of the adhesive tape 120 is wound up. In this process, the first adhesive segment 122 becomes shorter, the length of the connecting segment 123 is unchanged, and the second adhesive segment 121 becomes longer.
And since the diameter of the gear 101 is the same as the diameter of the drum 110, the linear speed of the gear 101 and the drum 110 is the same. Since the gear 101 is fixedly mounted on the rotating shaft 100, the rotating shaft 100 can be driven to rotate, the angular speed of the rotating shaft 100 is the same as that of the gear 101, that is, the speed of the rotating shaft 100 moving along the second direction is the same as the linear speed of the gear 101, that is, the linear speed of the rotating drum 110. The arrangement is such that when the rotation shaft 100 rotates synchronously with the drum 110 to wind the first pasting section 122 after the angle formed between the first pasting section 122 and the connecting section 123 is 60 °, the angle formed between the first pasting section 122 and the connecting section 123 is kept unchanged until the winding is completed. The accuracy of detection is improved, and errors possibly caused by manual detection are avoided.
The foregoing description of the preferred embodiments of the invention is not intended to be limiting, but rather is intended to cover all modifications, equivalents, alternatives, and improvements that fall within the spirit and scope of the invention.
