Description

Technical Field

[0001] This solution belongs to the field of strength testing technology, specifically involving a multi-point steel structure strength testing device. Background Technology

[0002] Utility model patent CN218239670U discloses a steel structure beam and column bending strength testing device, relating to the field of prefabricated building steel structure technology. It includes two support platforms with a connecting seat fixed between them. Each support platform has a limiting groove at its top, and a connecting frame is fixed to one side of each platform. Each connecting frame has a limiting cylinder fixed to its top, and limiting plates are fixed to the piston rods of both cylinders. A fixed frame slides along one side of the connecting seat. The advantages of this utility model are: the two limiting cylinders can move the two limiting plates downwards, and the interaction between the limiting plates and the limiting grooves limits the position of the steel structure beam and column, facilitating bending strength testing; the pressing cylinder can move the pressing plate to press down on the steel structure beam and column, and the pressure sensor and pressure display can detect the pressing value, thus testing the bending strength of the steel structure beam and column.

[0003] However, the device has certain shortcomings in use. It is not convenient to adjust the device to perform strength testing at any position of the steel structure. At the same time, the strength testing force range of the device is not easy to control. Utility Model Content

[0004] The purpose of this solution is to provide a multi-point steel structure strength testing device to solve the problems that the device is not convenient to adjust for strength testing at arbitrary locations on the steel structure, and that the force range of the strength testing is not easy to control.

[0005] To achieve the above objectives, this solution provides a multi-point steel structure strength testing device, including a frame, a side plate fixedly connected inside the frame, a bracket fixedly connected to the upper end of the side plate, a pressure plate slidably connected inside the bracket, a screw threadedly connected inside the bracket, the screw and the pressure plate being connected by a bearing, a motor fixedly installed in the middle of the upper end of the frame, the motor's shaft passing through the frame and rotatably connected to the frame, and a detection mechanism being provided on the motor's shaft.

[0006] The principle of this solution is as follows: During use, the steel structure is placed on the side plate. The screw is manually rotated, causing it to rotate and the support to move in a threaded motion, thus moving the pressure plate and contacting the steel structure, pressing it firmly against the side plate. Then, according to the detection position adjustment device, the motor is started. The motor drives the guide seat to rotate, and the motor drives the lead screw to rotate. The lead screw rotates and the slider moves in a threaded motion, thus moving the slider. The slider drives the support shaft to move, and the support shaft drives the carriage to move, thereby moving the cylinder and pressure head. Point strength testing can be performed at any location. Then, according to the detection position and detection range adjustment device, the bidirectional screw is manually rotated, causing the support plate to move in a threaded motion, thus adjusting the stress area of ​​the steel structure. The area of ​​the stress area can be adjusted according to the detection requirements. The cylinder is started, driving the cylinder rod to extend, which in turn moves the pressure head, causing it to contact the steel structure and perform a compression test.

[0007] The technical advantage of this solution is that by driving the guide seat to rotate via a motor, and by driving the lead screw to rotate and the slider to make threaded motion via a motor, the positions of the cylinder and the pressure head can be moved, enabling point strength detection at any position.

[0008] The steel structure is supported by a support plate, and the stress area of ​​the steel structure can be adjusted by rotating the bidirectional screw and the support plate to make threaded movements. The area of ​​the stress area to be tested can also be adjusted according to the testing requirements.

[0009] Furthermore, the testing mechanism includes a guide seat, with the lower end of the motor shaft fixedly connected to the guide seat. A slider is slidably connected inside the guide seat. A motor is fixedly installed at the left end of the guide seat, with the output end of the motor passing through the guide seat and rotatably connected to it. A lead screw is fixedly connected to the end of the motor's output end. A support shaft is installed inside the slider via a bearing, and a carriage is fixedly connected to the lower end of the support shaft. A support plate is slidably connected to the surface of the carriage, and a double-ended screw is threadedly connected inside the support plate. By driving the guide seat to rotate with the motor, and by driving the lead screw to rotate and the slider to perform threaded movement, the positions of the cylinder and the pressure head move, allowing point strength testing at any location. The support plate supports the steel structure through contact, and by rotating the double-ended screw and the support plate to perform threaded movement, the stress area of ​​the steel structure can be adjusted, and the area of ​​the stress area can be adjusted according to the testing requirements.

[0010] Furthermore, the lead screw and guide seat are rotatably connected, and the lead screw and slider are connected by a thread. By setting the lead screw, the slider is driven to move.

[0011] Furthermore, a cylinder is fixedly mounted on the surface of the carriage, and a pressure head is fixedly connected to the end of the cylinder rod. By setting the cylinder, the pressure head is driven to move.

[0012] Furthermore, a slide bar is fixedly connected to the lower end of the carriage, and the slide bar is slidably connected to the frame. The slide bar provides auxiliary support for the carriage.

[0013] Furthermore, a limiting plate is fixedly connected to the surface of the carriage, and the limiting plate is rotatably connected to the bidirectional screw. By setting the limiting plate, the bidirectional screw is prevented from moving out of control.

[0014] Furthermore, a top rod is fixedly connected to the upper end of the guide seat, and the top rod is slidably connected to the frame. The top rod provides auxiliary support to the guide seat. Attached Figure Description

[0017] The implementation examples are basically as follows Figure 1 As shown, this embodiment provides a multi-point steel structure strength testing device, including a frame 1, a side plate 2 fixedly connected inside the frame 1, a bracket 3 fixedly connected to the upper end of the side plate 2, a pressure plate 4 slidably connected inside the bracket 3, a screw 5 threadedly connected inside the bracket 3, the screw 5 and the pressure plate 4 connected by a bearing, a motor 6 fixedly installed in the middle of the upper end of the frame 1, the rotating shaft of the motor 6 passing through the frame 1 and rotatably connected to the frame 1, and a detection mechanism 7 provided on the rotating shaft of the motor 6.

[0018] like Figures 1-4As shown, the detection mechanism 7 includes a guide seat 71. The lower end of the shaft of the motor 6 is fixedly connected to the guide seat 71. A slider 72 is slidably connected inside the guide seat 71. A motor 73 is fixedly installed at the left end of the guide seat 71. The output end of the motor 73 passes through the guide seat 71 and is rotatably connected to the guide seat 71. A lead screw 74 is fixedly connected to the end of the output end of the motor 73. The lead screw 74 is rotatably connected to the guide seat 71. The lead screw 74 and the slider 72 are connected by a thread. By setting the lead screw 74, the slider 72 is driven to move. A support shaft 75 is installed inside the slider 72 through a bearing. A slide 76 is fixedly connected to the lower end of the support shaft 75. A cylinder 77 is fixedly installed on the surface of the slide 76. A pressure head 78 is fixedly connected to the end of the cylinder rod of the cylinder 77. By setting the cylinder 77, the pressure head 78 is driven to move. A slide bar 79 is fixedly connected to the lower end of the slide 76. The slide bar 79 is slidably connected to the frame 1. By setting the slide bar 79, the slide 76 is provided with auxiliary support. A support plate 710 is slidably connected to the surface of the slide 76. A double-acting screw 711 is threadedly connected inside the support plate 710. A limit plate 712 is fixedly connected to the surface of the slide 76. The limit plate 712 and the double-acting screw 711 are rotatably connected. By setting the limit plate 712, the double-acting screw 711 is prevented from moving. A top rod 713 is fixedly connected to the upper end of the guide seat 71. The top rod 713 is slidably connected to the frame 1. By setting the top rod 713, the guide seat 71 is auxiliary supported. The guide seat 71 is driven to rotate by the motor 6, and the lead screw 74 is driven to rotate and the slider 72 is threaded by the motor 73. This causes the positions of the cylinder 77 and the pressure head 78 to move, allowing point strength testing at any position. The support plate 710 supports the steel structure by contacting it.

[0019] The specific implementation process of this utility model is as follows: In use, the steel structure is placed on the side plate 2, and the screw 5 is manually rotated. The rotation of the screw 5 and the support 3 make a threaded movement, thereby causing the pressure plate 4 to move and contact the steel structure, so that the steel structure is pressed tightly onto the side plate 2. Then, according to the detection position adjustment device, the motor 6 is started. The motor 6 drives the guide seat 71 to rotate, and the motor 73 is started. The motor 73 drives the lead screw 74 to rotate. The rotation of the lead screw 74 and the slider 72 make a threaded movement, thereby causing the slider 72 to move. The slider 72 drives the support shaft 75 to move. 5. The slide 76 is moved, which in turn moves the positions of the cylinder 77 and the pressure head 78, allowing point strength testing at any location. Then, according to the testing position and testing range adjustment device, the bidirectional screw 711 and the support plate 710 are manually rotated to make threaded movement, thus the stress area of ​​the steel structure can be adjusted, and the area of ​​the stress area can be adjusted according to the testing requirements. The cylinder 77 is started, and the cylinder 77 drives the cylinder rod to extend. The cylinder rod drives the pressure head 78 to move, so that the pressure head 78 moves and contacts the steel structure to perform extrusion testing on the steel structure.

[0020] The guide seat 71 is driven to rotate by the motor 6, and the lead screw 74 is driven to rotate and the slider 72 is driven to make threaded motion by the motor 73, thereby causing the cylinder 77 and the pressure head 78 to move, so that point strength detection can be performed at any position.
