Description

TECHNICAL FIELD

[0001] The present application relates to the field of steel structure anti-deformation detection equipment, more particularly, to a steel structure anti-deformation detection device. BACKGROUND

[0002] Steel structure is a structure composed of steel materials, and is one of the main building structure types. The structure is mainly composed of steel beams, steel columns, steel trusses and other components made of steel plates and shaped steel, and adopts rust removal and rust prevention processes such as silanization, pure manganese phosphating, water washing and drying, and galvanizing. Welding, bolts or rivets are usually used to connect between components or parts. Because the self-weight is lighter and the construction is simple, the steel structure is widely used in large workshops, venues, super high-rise buildings and other fields. The steel structure is prone to rust, and general steel structure needs to be rusted, galvanized or painted, and needs to be maintained regularly. Before the steel structure is made, in order to ensure the quality of the steel structure, a steel structure anti-deformation detection device needs to be used to pre-detect the anti-deformation of the steel material for making the steel structure.

[0003] The existing steel structure anti-deformation detection device is usually composed of an environment simulation box, a steel material fixing clamp, a load applying mechanism, an ultrasonic sensor and the like. The steel material fixing clamp, the load applying mechanism and the ultrasonic sensor are all installed in the environment simulation box. When used, the steel material is first clamped on the steel material fixing clamp, then the environment simulation box is closed, and then the environment simulation box creates the required environment, such as high temperature, low temperature and acid mist environment, in its interior. Then the load applying mechanism applies load to the steel material, and then the ultrasonic sensor monitors the shape change of the steel material in real time. However, the single detection result is not representative, and multiple steel samples need to be detected and multiple detection results need to be obtained. Comprehensive analysis of all results can reflect the real anti-deformation ability of the steel material. Thus, the steel sample needs to be frequently replaced, and the simulation environment needs to be frequently created and destroyed. This not only wastes energy, but also is time-consuming and laborious. Therefore, it is urgent to design a steel structure anti-deformation detection device. SUMMARY

[0047] Working principle:

[0048] Firstly, the counterweight 62 exerts a torsional force on the rotating cover 61 under the action of its own gravity, and then the rotating cover 61 twists and reciprocatingly swings with the hydraulic element 7, the caliber reducing element 8 and the clamping element 9 under the action of the torsional force, and then the swing of the splicing power element 6, the hydraulic element 7, the caliber reducing element 8 and the clamping element 9 exerts resistance, until the splicing power element 6, the hydraulic element 7, the caliber reducing element 8 and the clamping element 9 stop swinging in the natural state, at this time, there is a clamping element 9 vertically upward on each of the two hydraulic elements 7, then one end of the steel sample is inserted into the gap between the hexagonal column 71 and one clamping plate 92 through the first slit 86 and the steel perforation 84, and then the other end of the steel sample is inserted into the gap between the hexagonal column 71 and another clamping plate 92, then the corresponding pressure valve 96 and the lifting valve 98 are opened, and then the hydraulic oil is injected from the top of the pneumatic cylinder 94 and discharged from the bottom under the action of the external hydraulic pump, at the same time, the pneumatic cylinder 94 is driven to elongate, then the pneumatic cylinder 94 presses the clamping plate 92 on the surface of the steel sample, and then the steel sample is clamped and fixed, at this time, the steel sample is located directly above the rotating outer cylinder 304, then the corresponding pressure valve 96 and the lifting valve 98 are closed, and then a torsional force is exerted on the splicing power element 6, the hydraulic element 7, the caliber reducing element 8 and the clamping element 9, so that the hydraulic element 7 rotates by 60 degrees, then the hydraulic element 7 deflects by 60 degrees with the steel sample through the corresponding clamping element 9, at this time, the clamping element 9 near the steel sample on the hydraulic element 7 is in the vertical upward state, then the second steel sample is fixed in the same way as described above, and then the third, fourth, fifth and sixth steel samples are fixed in the same way as described above, after the fixing is completed, the splicing power element 6, the hydraulic element 7, the caliber reducing element 8 and the clamping element 9 are in the natural static state, at this time, the first steel sample is located directly above the rotating outer cylinder 304, the electric telescopic rod 301 is controlled to perform the first stage of contraction through the intelligent control display screen 12, then the extension frame 3 moves with the splicing power element 6, the hydraulic element 7, the caliber reducing element 8, the clamping element 9 and the steel sample to the inside of the environmental simulation cavity 13, then the inner wall of the environmental simulation cavity 13 contacts the surface of the slope elastic ring 83 and exerts a rightward pushing force on it, then the caliber reducing element 8 moves rightward relative to the isosceles triangle strip 308 under the action of the pushing force, then the isosceles triangle strip 308 and the ultrasonic inductor 309 slide in the second slit 89, then the first stage of contraction of the electric telescopic rod 301 is completed, at this time, the rotating cover 61 still blocks the environmental simulation cavity 13, then a leftward pushing force is exerted on the caliber reducing element 8, then the inner wall of the environmental simulation cavity 13 exerts a radial pressure on the slope elastic ring 83 and the sealing rubber ring 82, then the slope elastic ring 83 and the sealing rubber ring 82 contract radially, then the sealing rubber ring 82 is inserted into the environmental simulation cavity 13, then the electric telescopic rod 301 is controlled to perform the second stage of contraction through the intelligent control display screen 12, then the splicing power element 6, the hydraulic element 7, the clamping element 9 and the steel sample move leftward,And the caliber reducer 8 is fixed due to the friction between the sealing rubber ring 82 and the inner wall of the environment simulation cavity 13, then the cavities on both sides of the splicing power element 6 in the environment simulation cavity 13 are connected through the offset distance hole 15 and the accommodating flat tube 21, then the liquid power element 7 at the right end of the isosceles triangle strip 308 exerts a thrust force on the caliber reducer 8, then the caliber reducer 8 moves to the left, then the second stage of the electric telescopic rod 301 is retracted, at this time the sealing plug 306 is inserted into the environment simulation cavity 13, the limiting cap 307 is attached to the right end surface of the environment simulation block 11, the central elastic conductor 64 is inserted into the central pit 509 and contacts with the conductive disc 510, the eccentric elastic conductor 65 is inserted into the annular pit 511 and contacts with the conductive ring 512, the tapered element 63 is inserted into the tapered groove 505 and the tapered slot 508, the engagement tooth 66 is engaged with the fixed oblique tooth 506, then the circulating simulation gas such as high temperature gas and low temperature gas is introduced into the environment simulation cavity 13 through the environment simulation pipe 16, until the environment in the environment simulation cavity 13 reaches the requirement, then the intelligent control display screen 12 controls the servo adjusting motor 23 to rotate, then the threaded rod 22 rotates with the servo adjusting motor 23, then the end righting block 24 moves under the action of the threaded cooperation with the threaded rod 22, then the end righting block 24 moves with the middle righting block 26 and the load applying plate 29 through the electric telescopic cylinder 25, then the load applying plate 29 moves horizontally relative to the steel sample to adjust the stress point of the steel sample, then the electric telescopic cylinder 25 is elongated through the intelligent control display screen 12, then the electric telescopic cylinder 25 moves downward with the load applying plate 29 and applies detection force to the steel sample, then the isosceles triangle strip 308 naturally droops under the action of its own gravity, at this time the ultrasonic sensor 309 is vertically upward, then the ultrasonic sensor 309 detects the shape of the steel sample being detected in real time, then the ultrasonic sensor 309 sends the detection result to the wireless transceiver 310, then the wireless transceiver 310 wirelessly transmits the detection result to the intelligent control display screen 12, which processes, displays and records the detection result, then the steel sample detection is completed, then the intelligent control display screen 12 controls the electric telescopic cylinder 25 to shorten, then the load applying plate 29 moves upward, then the load applying plate 29 resets, then the intelligent control display screen 12 controls the electromagnetic bolt 43 to retract, then the electromagnetic bolt 43 is pulled out of the directional hole 42, releasing the restriction on the directional disc 41, then the intelligent control display screen 12 controls the output shaft of the servo replacement motor 14 to rotate by sixty degrees, then the output shaft of the servo replacement motor 14 rotates with the directional disc 41 by sixty degrees, at this time the electromagnetic bolt 43 is aligned with the corresponding directional hole 42, then the directional disc 41 rotates with the rotating column 501 by sixty degrees, then the rotating column 501 rotates with the tapered element 63 by sixty degrees through the meshing action of the fixed oblique tooth 506 and the engagement tooth 66, then the tapered element 63 rotates with the two liquid power elements 7 by sixty degrees through the rotating cover 61 and the rotating outer cylinder 304,During this process, the isosceles triangular strip 308 hangs naturally under its own weight, ensuring that the ultrasonic sensor 309 remains vertically upward. Then, the two hydraulic components 7 rotate the steel sample 60 degrees via the corresponding clamping components 9. Next, the tested steel sample moves away from under the load application plate 29, and another steel sample adjacent to it moves to the underside of the load application plate 29. Then, the intelligent control display screen 12 controls the electromagnetic pin 43 to insert into the corresponding directional hole 42, fixing the position of this steel sample. The same steps are then repeated for the second steel sample. The third, fourth, fifth, and sixth steel samples were tested. After the tests were completed, the flow of simulated gas into the environmental simulation cavity 13 was stopped. Then, the electric telescopic rod 301 was extended via the intelligent control display screen 12. The extension plate 302, along with the splicing power component 6, hydraulic component 7, clamping component 9, and the tested steel samples, moved to the right via the rotating outer cylinder 304. At the same time, the diameter reduction component 8 remained fixed due to the friction between the sealing rubber ring 82 and the inner wall of the environmental simulation cavity 13. The isosceles triangular strip 308 and the ultrasonic sensor 309 slid inside the second slit 89. The tested steel samples were then... The internal sliding of the slit 86 greatly reduces the opening at the right end of the environmental simulation cavity 13, thereby greatly reducing the leakage of simulated gas and the degree of damage to the simulated environment inside the environmental simulation cavity 13. This helps to quickly restore the target simulated environment state, reduces energy consumption, and saves time and effort. Then, the hydraulic component 7 at the left end of the isosceles triangular strip 308 contacts the aperture reduction component 8 and applies a rightward thrust to it. After that, the aperture reduction component 8 slides to the right, and then the rotating cover 61 separates from the area where the offset hole 15 is located and moves to its right side. Then, the right end of the environmental simulation cavity 13 is blocked by the rotating cover 61. Afterwards, the reducing nozzle 8 and its left-side hydraulic actuator 7 move out of the environmental simulation cavity 13, while the rotating cover 61 remains sealed inside. Then, the corresponding pressure valve 96 and lifting valve 98 are opened. Hydraulic oil, driven by an external hydraulic pump, is injected from the bottom of the pneumatic cylinder 94 and discharged from its top, simultaneously causing the pneumatic cylinder 94 to shorten. The pneumatic cylinder 94 then moves the clamping plate 92 away from the surface of the tested steel sample, releasing the sample. The tested steel sample is then removed, and a new steel sample is installed and tested in the same manner.
