Description

Technical Field

[0001] This invention relates to the field of steel structure testing equipment, and more specifically, to a test device for the deformation resistance of building steel structures and its usage method. Background Technology

[0002] Steel structures are structures made of steel materials and are one of the main types of building structures. They are primarily composed of steel beams, columns, trusses, and other components made of shaped steel and steel plates, and undergo rust removal and prevention processes such as silanization, pure manganese phosphating, water washing and drying, and galvanizing. The components are typically connected by welds, bolts, or rivets. Due to their light weight and simple construction, steel structures are widely used in large factories, stadiums, high-rise buildings, bridges, and other fields. Steel structures are prone to corrosion, and generally require rust removal, galvanizing, or painting, as well as regular maintenance. During the production process, it is usually necessary to test the deformation resistance of the steel structure.

[0003] In existing technologies, when inspecting steel plates, the steel plates are usually placed on a support and inspected by a hydraulic cylinder. However, the lack of fixation of the steel plates during the inspection process makes them prone to displacement and detachment, affecting the inspection results and threatening the personal safety of the workers.

[0004] Therefore, we have made improvements to this and proposed a testing device for the deformation resistance of building steel structures and its usage method. Summary of the Invention

[0005] 1. The technical problem that the invention aims to solve

[0006] In view of the defects and deficiencies of the existing technology, the present invention provides a test device for the deformation resistance of building steel structure and its usage method. The present invention uses the cooperation of linkage, lifting and sliding parts to make the steel plate fit and fix the upper surface of the base, the lower surface of the fixed plate and the inner side of the lifting plate. This can effectively prevent the steel plate from shifting, falling off or warping during the test, thus affecting the test results and ensuring the personal safety of the staff.

[0007] 2. Technical Solution

[0008] To achieve the above objectives, the technical solution provided by the present invention is as follows:

[0009] The present invention provides a deformation resistance testing device for building steel structures, comprising a base, wherein a mounting frame is fixedly connected to the upper surface of the base, a hydraulic cylinder is fixedly connected to the center of the upper surface of the mounting frame, and the output end of the hydraulic cylinder extends to the bottom of the mounting frame and is fixedly connected to a pressure block.

[0010] The upper surface of the base has two lifting slots. The inner surface of the lifting slots is slidably connected to a lifting component for fixing the steel plate in the vertical direction. The inside of the lifting component is slidably connected to a sliding component for fixing the steel plate in the horizontal direction. A cylinder is fixedly connected to the center of the bottom surface of the base, and a linkage component is fixedly connected to the output end of the cylinder.

[0011] Furthermore, the lifting component includes a lifting plate that slides inside a lifting groove. Two sliding grooves are formed on the inner surface of the lifting groove. A connecting block is slidably connected to the inner surface of the sliding groove and is fixedly connected to the lifting plate. A roller is rotatably connected to the inner side of the connecting block via a rotating rod and is rolled on the inner surface of the sliding groove.

[0012] Furthermore, the sliding member includes a fixed plate, and a second sliding groove is provided through the upper surface of the lifting plate, and the fixed plate is slidably disposed inside the second sliding groove.

[0013] Furthermore, the linkage component includes a connecting plate, which is fixedly connected to the output end of the cylinder. Mounting blocks are fixedly connected to both sides of the upper surface of the connecting plate. A rotating plate is rotatably connected between the mounting blocks and the fixed plate via a connecting shaft. A limiting block is fixedly connected to the bottom side of the fixed plate on one side of the connecting shaft.

[0014] Furthermore, the inner top surface of the base is provided with a movable groove below the lifting groove, and the rotating plate is movably arranged inside the movable groove.

[0015] Furthermore, two limiting cylinders are fixedly connected to the inner bottom surface of the base, and a sliding rod is slidably connected to the inner surface of the limiting cylinder. The sliding rod is fixedly connected to the lower surface of the connecting plate.

[0016] Furthermore, the steel plate is placed on the base, and the steel plate is fitted to the upper surface of the base, the lower surface of the fixed plate, and the inner side of the lifting plate.

[0017] A method for using a deformation resistance testing device for building steel structures, characterized by the following specific operation: When it is necessary to fix a steel plate, manually pass the steel plate through the bottom of the fixing plate and place it on the upper surface of the base. Then, the cylinder operates to drive the mounting block to move downward. The mounting block drives the lifting plate and the fixing plate to slide downward inside the lifting groove. When the lower surface of the fixing plate is in contact with the upper surface of the steel plate, the steel plate is fixed in the vertical direction. The mounting block continues to move downward and drives the fixing plate to continue to move to the left. When the inner side of the fixing plate contacts the right side of the steel plate, the cylinder stops working. At this time, the steel plate is in contact with the upper surface of the base, the lower surface of the fixing plate, and the inner side of the lifting plate, thereby achieving the fixation of the steel plate.

[0018] Furthermore, when it is necessary to release the steel plate, the cylinder starts to work, causing the connecting plate and the slide rod fixedly connected to the connecting plate to slide upward inside the limiting cylinder. The movement of the connecting plate causes the mounting block to move upward synchronously. The mounting block and the fixed plate are rotatably connected by a connecting shaft, and the movement of the mounting block causes the fixed plate to move to the right inside the second slide groove, thereby releasing the horizontal fixation of the steel plate.

[0019] When the fixed plate contacts the right side of the inner surface of the slide groove two, the rotating plate and the inclined surface of the limiting block are fitted together. At this time, the mounting block, the rotating plate, and the lifting plate are subjected to an upward vertical force. The mounting block continues to move upward, pushing the fixed plate, the lifting plate, and the connecting block fixedly connected to the lifting plate to slide upward inside the slide groove one. The setting of the roller makes the sliding of the connecting block smoother. The upward movement of the fixed plate separates the lower surface of the fixed plate from the upper surface of the steel plate, thereby releasing the vertical fixation of the steel plate and thus releasing the fixation effect on the steel plate.

[0020] Furthermore, during use, after the steel plate is fixed, the hydraulic cylinder starts working to move the pressure block downwards to squeeze the steel plate. The applied pressure is calculated and read through the pressure supplied by the hydraulic cylinder.

[0021] 3. Beneficial effects

[0022] Compared with the prior art, the technical solution provided by this invention has the following advantages:

[0023] This invention, through the combined use of linkage components, lifting components, and sliding components, ensures that the steel plate is firmly attached to the upper surface of the base, the lower surface of the fixed plate, and the inner side of the lifting plate. This effectively prevents the steel plate from shifting, falling off, or warping during the testing process, thus affecting the test results and ensuring the personal safety of the staff.

[0031] The present invention will be further described below with reference to the accompanying drawings and embodiments:

[0034] After the steel plate 2 is fixed, the hydraulic cylinder 6 starts to work, driving the pressure block 61 to move downward to squeeze the steel plate 2. By calculating and reading the applied pressure through the pressure supplied by the hydraulic cylinder 6, the deformation resistance of the steel plate 2 can be tested.

[0035] Two lifting slots 3 are provided on the upper surface of the base 1. A lifting component for fixing the steel plate 2 in the vertical direction is slidably connected to the inner surface of the lifting slot 3. A sliding component for fixing the steel plate 2 in the horizontal direction is slidably connected inside the lifting component. A cylinder 4 is fixedly connected to the center of the inner bottom surface of the base 1. A linkage component is fixedly connected to the output end of the cylinder 4.

[0036] The lifting component includes a lifting plate 31, which slides inside the lifting groove 3. Two sliding grooves 32 are formed on the inner surface of the lifting groove 3. A connecting block 33 is slidably connected to the inner surface of the sliding groove 32. The connecting block 33 is fixedly connected to the lifting plate 31. A roller 34 is rotatably connected to the inner side of the connecting block 33 through a rotating rod. The roller 34 is rolled on the inner surface of the sliding groove 32.

[0037] The sliding component includes a fixed plate 44, and a sliding groove 46 is provided through the upper surface of the lifting plate 31. The fixed plate 44 is slidably disposed inside the sliding groove 46.

[0038] The linkage includes a connecting plate 41, which is fixedly connected to the output end of the cylinder 4. Mounting blocks 42 are fixedly connected to both sides of the upper surface of the connecting plate 41. A rotating plate 43 is rotatably connected between the mounting blocks 42 and the fixed plate 44 via a connecting shaft. A limiting block 47 is fixedly connected to the bottom side of the fixed plate 44 on one side of the connecting shaft.

[0039] The inner top surface of the base 1 is provided with a movable groove 45 located below the lifting groove 3, and the rotating plate 43 is movable inside the movable groove 45.

[0040] Two limiting cylinders 5 are fixedly connected to the inner bottom surface of the base 1. A sliding rod 51 is slidably connected to the inner surface of the limiting cylinder 5. The sliding rod 51 is fixedly connected to the lower surface of the connecting plate 41.

[0041] The steel plate 2 is placed on the base 1, and the steel plate 2 is fitted to the upper surface of the base 1, the lower surface of the fixing plate 44 and the inner side of the lifting plate 31.

[0042] By using the linkage, lifting and sliding parts in combination, the steel plate 2 is fixed to the upper surface of the base 1, the lower surface of the fixed plate 44 and the inner side of the lifting plate 31. This can effectively prevent the steel plate from shifting, falling off or tilting during the testing process, thus affecting the test results and ensuring the personal safety of the staff.

[0043] This invention achieves a fixed effect on the steel plate 2, preventing it from shifting or falling off during the testing of the steel plate 2's resistance to deformation, thus affecting the measurement results.

[0044] The present invention fixes the steel plate during the testing process, thereby preventing the steel plate from shifting or falling off, which would affect the test results and thus ensure the personal safety of the staff.

[0045] Example 2

[0046] from Figure 1-6 As can be seen, the specific operation of a steel structure deformation resistance testing device is as follows: When it is necessary to fix the steel plate 2, manually pass the steel plate 2 through the bottom of the fixing plate 44 and place it on the upper surface of the base 1. Then, the cylinder 4 works to drive the mounting block 42 to move downward. The mounting block 42 drives the lifting plate 31 and the fixing plate 44 to slide downward inside the lifting groove 3. When the lower surface of the fixing plate 44 is in contact with the upper surface of the steel plate 2, the steel plate 2 is fixed in the vertical direction. The mounting block 42 continues to move downward and drives the fixing plate 44 to continue to move to the left. When the inner side of the fixing plate 44 contacts the right side of the steel plate 2, the cylinder 4 stops working. At this time, the steel plate 2 is in contact with the upper surface of the base 1, the lower surface of the fixing plate 44 and the inner side of the lifting plate 31, thereby fixing the steel plate 2.

[0047] When it is necessary to release the fixation of the steel plate 2, the cylinder 4 starts to work and drives the connecting plate 41 and the slide rod 51 fixedly connected to the connecting plate 41 to slide upward inside the limiting cylinder 5. The movement of the connecting plate 41 drives the mounting block 42 to move upward synchronously. The mounting block 42 and the fixed plate 44 are rotatably connected by a connecting shaft and a rotating plate 43. The movement of the mounting block 42 drives the fixed plate 44 to move to the right inside the slide groove 46, thereby releasing the fixation of the steel plate 2 in the horizontal direction.

[0048] When the fixed plate 44 contacts the right side of the inner surface of the slide 46, the rotating plate 43 is fitted with the inclined surface of the limiting block 47. At this time, the mounting block 42, the rotating plate 43, and the lifting plate 31 are subjected to an upward vertical force. The mounting block 42 continues to move upward, pushing the fixed plate 44, the lifting plate 31, and the connecting block 33 fixedly connected to the lifting plate 31 to slide upward inside the slide 32. The setting of the roller 34 makes the sliding of the connecting block 33 smoother. The upward movement of the fixed plate 44 separates the lower surface of the fixed plate 44 from the upper surface of the steel plate 2, thereby releasing the vertical fixation of the steel plate 2 and thus releasing the fixation effect on the steel plate 2.

[0049] In use, after the steel plate 2 is fixed, the hydraulic cylinder 6 starts to work, driving the pressure block 61 to move downward to squeeze the steel plate 2. The pressure applied is calculated and read through the pressure supplied by the hydraulic cylinder 6.

This description is not restrictive, and the figures shown are only one embodiment of the present invention; the actual structure is not limited thereto. Therefore, if those skilled in the art are inspired by this description and design similar structures and embodiments without departing from the spirit of the present invention, such designs should fall within the protection scope of the present invention.
