Technical Field

[0001] The utility model provides a steel structure detection limit device, belonging to the technical field of steel structure detection devices. Background Art

[0002] Steel structure refers to a structure made mainly of steel, which is widely used in buildings, bridges, towers, industrial equipment, offshore platforms and other fields. Steel has high strength and good plasticity, and can maintain structural stability while bearing large loads, which makes the steel structure have excellent bearing capacity. Compared with other building materials of the same strength, the density of steel is lower, so that under the premise of the same bearing capacity, the dead weight of the steel structure is lighter, which is conducive to reducing the foundation burden and reducing transportation and installation costs. In addition, steel structure components can be standardized and mass-produced in the factory. The quality of the components is guaranteed through precise cutting, welding, anti-corrosion treatment and other processes, and then transported to the construction site for rapid assembly, shortening the construction period and improving construction efficiency.

[0003] When testing steel, in order to keep the steel stable during the testing process and improve the accuracy of the test data, the steel needs to be fixed on the testing platform. However, the steel needs to be tested at more than one position, and multiple locations of the steel need to be tested. The current testing device cannot move after the steel is fixed. Therefore, the steel needs to be removed and repositioned and fixed, which is more troublesome. Utility Model Content

[0018] The utility model is further described below in conjunction with the accompanying drawings.

[0019] according to Figure 1—4: The utility model provides a steel structure detection limit device: including a detection platform 1; the detection platform 1 is provided with a T-shaped groove 2 below the detection position, two sliding T-shaped blocks 3 are respectively provided on both sides of the T-shaped groove 2, a U-shaped frame 4 is provided above the T-shaped block 3, a fixing frame 6 is installed in the middle of the two side plates of the U-shaped frame 4 through a bearing 5, the fixing frame 6 is located in the middle of the two side plates of the U-shaped frame 4, and a plurality of threaded screw rods 7 are provided at equal angles, and a plurality of groups of fixing holes 8 are provided on the two side plates of the U-shaped frame 4, located at a screw rod Fixing pins 9 are inserted into the fixing holes 8 on both sides of 7, and a rubber sleeve is installed at one end of the screw rod 7 located in the fixing frame 6. By setting a T-shaped slot 2, a T-shaped block 3 is set in the T-shaped slot 2 to drive the U-shaped frame 4 to slide, so that the device can slide after fixing the steel. By setting a fixing frame 6 connected to the U-shaped frame 4 using a bearing 5, the device can rotate after fixing the steel. By setting the fixing holes 8 and the fixing pins 9, the screw rod 7 can be fixed after fixing the steel, so that the device can detect any position of the steel.

[0020] Among them, the middle parts of the two side plates of the two U-shaped frames 4 are respectively provided with coaxial through holes, the bearing 5 is installed in the through holes, the outer diameter of the through holes is the same as the outer diameter of the bearing 5, the fixing frame 6 is O-shaped, and the outer diameter is the same as the inner diameter of the bearing 5, and the middle part of the fixing frame 6 is provided with a plurality of threaded holes corresponding to the screw rod 7 at equal angles, and the screw rod 7 is installed in the threaded holes; in this way, the fixing frame 6 is relatively tight when installed on the U-shaped frame 4;

[0021] The distance between any two adjacent fixing holes 8 is the diameter of the screw rod 7; thus, after the fixing pin 9 is inserted into the fixing hole 8, the fixing pin 9 can fix the screw rod 7, so that the steel can be tested;

[0022] Among them, a rotating table is provided at one end of the screw rod 7 located outside the fixing frame 6. After the screw rod 7 fixes the steel, the lower end surface of the rotating table at the lower end does not contact the bottom plate of the U-shaped frame 4. In this way, when one position of the steel is detected, the fixing pin 9 is taken out and the fixing frame 6 can be rotated directly.

[0023] The principle of the utility model is as follows: when in use, first insert the steel into the two fixing frames 6, then screw the plurality of screw rods 7 into the plurality of threaded holes of the fixing frames 6 respectively, then put the rubber sleeve on the end of the screw rod 7 and fix the steel, then insert the fixing pin 9 into a group of fixing holes 8 to fix the screw rod 7, and then inspect the steel. When one inspection is completed, if another part of the steel needs to be inspected, push the two U-shaped frames 4, and the T-shaped block will slide in the T-shaped groove 2, which can change the position of the steel at the inspection point. When it is necessary to inspect other angular positions of the steel, pull out the fixing pin 9, rotate the fixing frame 6, and when the position to be inspected is below the inspection point, insert the two fixing pins 9 into the fixing holes 8 on both sides of the screw rod 7. The device can inspect any position of the steel.

[0024] The above description of the utility model and its implementation methods is not restrictive. The drawings show only one implementation method of the utility model, and the actual structure is not limited thereto. In short, if ordinary technicians in this field are inspired by it and design structural methods and embodiments similar to the technical solution without creativity without departing from the purpose of the invention of the utility model, they should all fall within the protection scope of the utility model.
