Description

Technical Field

[0001] The present invention relates to the technical field of steel structure detection devices, and more specifically, to a building steel structure anti-deformation testing device and a use method thereof. Background Art

[0002] Steel structure is a structure made of steel materials. It is one of the main types of building structures. The structure is mainly composed of steel beams, steel columns, steel trusses and other components made of steel sections and steel plates. Rust removal and rust prevention processes such as silanization, pure manganese phosphating, water washing and drying, and galvanizing are used. Welds, bolts or rivets are usually used to connect the components or parts. Because of its light weight and simple construction, it is widely used in large factories, venues, super high-rise buildings, bridges and other fields. Steel structures are prone to rust. Generally, steel structures need to be rust-free, galvanized or painted, and they need regular maintenance. During the production process, it is usually necessary to test the steel structure's ability to resist deformation.

[0003] In the prior art, when testing steel plates, the steel plates are usually placed on supports and tested by hydraulic cylinders. However, the steel plates are not fixed during the testing process, which causes the steel plates to easily shift or fall off, affecting the test results and threatening the personal safety of the staff.

[0004] Therefore, we have made improvements to this and proposed a building steel structure anti-deformation testing device and its use method. Summary of the invention

[0010] The upper surface of the base is provided with two lifting grooves, the inner surface of the lifting grooves is slidably connected with a lifting member for fixing the steel plate in the vertical direction, the inner sliding connection of the lifting member is used to fix the steel plate in the horizontal direction, the center position of the inner bottom surface of the base is fixedly connected with a cylinder, and the output end of the cylinder is fixedly connected with a linkage member.

[0011] Furthermore, the lifting member includes a lifting plate, which slides inside the lifting slot.

A rotating plate is rotatably connected between the mounting block and the fixed plate via a connecting shaft, and a limiting block is fixedly connected to the bottom side of the fixed plate on one side of the connecting shaft.

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

[0015] Furthermore, the inner bottom surface of the base is fixedly connected to two limiting cylinders, the inner surface of the limiting cylinder is slidably connected to a sliding rod, and 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 with the upper surface of the base, the lower surface of the fixing plate and the inner side surface of the lifting plate.

[0017] A method for using a building steel structure anti-deformation testing device, characterized in that the specific operation is as follows: when it is necessary to fix the 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 works to drive the mounting block to move downward, and the mounting block drives the lifting plate and the fixing plate to slide downward inside the lifting slot, when the lower surface of the fixing plate fits 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 surface of the fixing plate contacts the right side surface of the steel plate, the cylinder stops working, at this time the steel plate is fitted with the upper surface of the base, the lower surface of the fixing plate and the inner side surface of the lifting plate, thereby fixing the steel plate.

[0039] A movable groove 45 is provided on the inner top surface of the base 1 below the lifting groove 3 , and the rotating plate 43 is movably arranged inside the movable groove 45 .

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

[0045] Example 2

[0046] from Figure 1-6 It can be seen that a method for using a building steel structure anti-deformation testing device is specifically operated as follows: when the steel plate 2 needs to be fixed, the steel plate 2 is manually passed through the bottom of the fixing plate 44 and placed on the upper surface of the base 1, and then the cylinder 4 works to drive the mounting block 42 to move downward, and 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 surface of the fixing plate 44 contacts the right side surface 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 surface of the lifting plate 31 are all in contact with each other, thereby achieving the fixation of the steel plate 2.

[0047] When the steel plate 2 needs to be released, the cylinder 4 starts to work to drive the connecting plate 41 and the slide bar 51 fixedly connected to the connecting plate 41 to slide upward inside the limiting cylinder 5, and 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 with a rotating plate 43 via a connecting shaft, and the movement of the mounting block 42 drives the fixed plate 44 to move rightward inside the second 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 surface of the inner surface of the second slide groove 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, and 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 groove 1 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 fixation of the steel plate 2 in the vertical direction, and then releasing the fixing effect of the steel plate 2.

[0049] When in use, after the steel plate 2 is fixed, the hydraulic cylinder 6 starts to work to drive the pressing block 61 to move downward to squeeze the steel plate 2, and the applied pressure is calculated and read by the supply pressure of the hydraulic cylinder 6.
