Description

Technical Field

[0001] This application relates to the field of building steel structure testing technology, and in particular to a building steel structure strength testing device and testing method. Background Technology

[0002] Before construction work begins, the raw materials, such as steel structures, must undergo strength testing. Only after the tests are passed can assembly and construction proceed.

[0003] Existing steel structure strength testing equipment includes a testing platform, a pressure plate positioned directly above the platform, and a lifting mechanism for raising and lowering the pressure plate. A pressure sensor is embedded in the lower surface of the pressure plate facing the testing platform. The pressure sensor is electrically connected to a controller, which in turn is electrically connected to a display screen. During testing, the steel structure to be tested is placed on the testing platform so that it is directly below the pressure plate. The lifting mechanism then moves the pressure plate closer to the testing platform, pressing it against the upper surface of the steel structure. Because the pressure sensor's detection end is in contact with the upper surface of the steel structure, the sensor detects the reverse force from the structure, i.e., pressure data. This pressure data is transmitted to the controller, which then controls the display screen to show the pressure data. After the pressure plate is lowered to a designated height, the lifting mechanism raises it again to complete the test. During this process, the testing personnel can assess the strength of the steel structure by observing the pressure data displayed on the screen and whether cracks appear on the outer surface of the steel structure after the test.

[0004] Regarding the aforementioned technologies, the inventors have found that when testing building steel structures using the strength testing equipment, after testing a single building steel structure, the testing personnel need to move the tested steel structure off the workbench before replacing it with the next steel structure to be tested. This replacement operation reduces the testing efficiency for batches of building steel structures and therefore needs to be improved. Summary of the Invention

[0005] To improve the efficiency of testing building steel structures, this application provides a testing device and method for testing the strength of building steel structures.

[0006] Firstly, this application provides a strength testing device for building steel structures, which adopts the following technical solution:

[0007] A steel structure strength testing device includes a testing platform with several storage frames. Within each storage frame, a steel structure to be tested is stacked sequentially along its height. A push plate is positioned near the bottom of each storage frame on the testing platform. A driving assembly is provided on the testing platform to drive all push plates to move towards or away from their corresponding storage frames. When a push plate approaches a corresponding storage frame, it presses the steel structure at the bottom of the storage frame against the push plate and the inner wall of the storage frame. The testing platform also includes a detection component for detecting and displaying the pressure exerted by the push plates on the steel structure. The driving assembly is also used to remove the tested steel structure from the storage frames.

[0008] By adopting the above technical solution, multiple sets of storage frames for placing building steel structures are set on the testing platform. Each storage frame is equipped with a push plate. When all push plates are moved towards the corresponding storage frame by the drive component, the push plate will abut against the outer surface of the building steel structure at the bottom of the storage frame. During this process, the testing component detects the pressure of the push plate on the steel structure, thus realizing the strength test of the building steel structure. After the pressure is completed, the building steel structure that has been tested can be pushed out of the storage frame again by the drive component; that is, the building steel structure at the bottom of the storage frame is pushed away from the storage frame. At this time, the remaining building steel structure in the storage frame will automatically move down under its own weight, thereby quickly entering the testing process of the next building steel structure, improving the testing efficiency. In addition, this application can test multiple building steel structures at the same time, further improving the testing efficiency.

[0009] Preferably, the driving assembly includes a turntable rotatably connected to the detection table, a rotating component for driving the turntable to rotate, several moving blocks, and a limiting plate; the moving blocks and push plates are arranged in a one-to-one correspondence, and the limiting plate has a limiting groove for each moving block to be inserted, the length direction of the limiting groove being parallel to the moving direction of the push plate; the turntable has an arc-shaped groove for the end of each moving block to be inserted, the moving block is inserted into the corresponding limiting groove, and one end of the moving block is slidably connected to the arc-shaped groove, and the other end is connected to the corresponding push plate.

[0010] By adopting the above technical solution, the rotating component drives the turntable to rotate, so that the end of the moving block moves along the arc direction of the arc groove. During the movement, the limiting block and the limiting groove limit the movement of the moving block, so that the moving block can only move back and forth along the length direction of the limiting groove. During the movement, the moving block drives the push plate to move back and forth, thereby realizing the movement control of all push plates.

[0011] Preferably, each of the movable blocks is rotatably connected to a rotating rod near the turntable, and the movable block is inserted into the inner wall of the corresponding arc-shaped groove through the rotating rod.

[0012] By adopting the above technical solution, the sliding connection between the moving block and the arc groove is realized by the rotating rod. Since the rotating rod is rotatably connected to the moving block, the sliding resistance when the moving block slides relative to the arc direction of the arc groove can be reduced by the rotating rod.

[0013] Preferably, the driving assembly includes a discharge plate, a discharge platform, a first lifting component, and a second lifting component; each of the storage frames has a material passage notch on its side wall, the discharge plate is inserted into the inner wall of the material passage notch, the first lifting component is used to drive the discharge plate to rise and fall to realize the opening and closing of the material passage notch, the building steel structure is located between the push plate and the discharge plate; the discharge platform is slidably connected to the testing platform along the height direction of the testing platform, and the discharge platform is located around the discharge plate, the second lifting component is used to drive the discharge platform to rise and fall.

[0014] By adopting the above technical solution, when inspecting the building steel structure at the bottom of the storage frame, the material passage gap is in a closed state. First, the push plate is driven to move to a designated position so that the building steel structure is clamped between the push plate and the unloading plate under the pressure of the push plate. After the inspection is completed, the unloading plate is driven to move down through the first lifting component to open the material passage gap. At this time, the push plate is driven again to push the building steel structure so that the building steel structure that has been inspected is pushed onto the unloading platform. The unloading platform is controlled to move down through the second lifting component so that the top of the unloading platform is always flush with the inspection platform, so that the building steel structure that has been inspected can be pushed onto the unloading platform in the future.

[0015] Preferably, the detection assembly includes a pressure sensor embedded in the side wall of each push plate, a controller electrically connected to all pressure sensors, and a display electrically connected to the controller. The pressure sensor is located on the side of the push plate facing the corresponding shelf. The detection end of the pressure sensor is used to detect the pressure exerted by the building steel structure on the push plate when the push plate abuts against the building steel structure. The controller is used to receive the pressure data detected by all pressure sensors and control the display to display the pressure data.

[0016] By adopting the above technical solution, when the push plate abuts against the building steel structure inside the storage frame, the detection end of the pressure sensor also abuts against the building steel structure. At this time, since the push plate applies a pushing force to the building steel structure, the pressure sensor can also detect the reverse pushing force applied by the building steel structure to the push plate. The controller displays the pressure data detected by all the pressure sensors on the display screen to facilitate the inspection personnel to observe the inspection data of the building steel structure at all positions.

[0017] Preferably, the inner wall of the storage frame is provided with a quantity detector for detecting the remaining amount of the building steel structure inside the storage frame. The quantity detector is electrically connected to the controller. The quantity detector is used to send a replenishment signal to the controller when the remaining amount of the building steel structure is lower than a preset quantity. When the controller receives the replenishment signal, it controls the display to display preset replenishment information.

[0018] By adopting the above technical solution, the surplus detector will monitor the quantity of building steel structure in the storage frame in real time, and issue a replenishment signal when the surplus of building steel structure is less than the preset quantity, so that the controller controls the display to show the replenishment information, which makes it convenient for the inspection personnel to replenish the building steel structure to be inspected in the storage frame in a timely manner.

[0019] Preferably, each of the storage frames is slidably connected to a limiting rod along its height direction. The limiting rod is attached to the side wall of the building steel structure, and the side of the building steel structure away from the limiting rod is attached to the inner wall of the storage frame near the material passage notch. The testing platform is also provided with a third lifting component, which is used to drive the limiting rod to rise and fall.

[0020] By adopting the above technical solution, since the size of the steel structure to be inserted in the storage frame is fixed, when the width of the steel structure to be tested is smaller than the internal width of the storage frame, that is, when there is a gap between the side wall of the steel structure and the inner wall of the storage frame, if the steel structure at the bottom of the storage frame that has been tested is pushed out of the storage frame, the remaining steel structure in the storage frame is prone to tilting towards the gap during the downward movement, causing the steel structure to be unable to move down in an orderly manner along the height direction of the storage frame. Therefore, a limiting rod is used to limit the position of the steel structure, so that the steel structures arranged sequentially along the height direction of the storage frame can always fit between the limiting rod and the inner wall of the storage frame; and the setting of the third lifting component can be used to drive the lifting of the limiting rod. Specifically, the third lifting component is used to drive the limiting rod to disengage from the side wall of the bottom steel structure before the push plate pushes the steel structure, so as to avoid the limiting rod obstructing the movement of the push plate.

[0021] Preferably, the third lifting component includes a linkage frame plate and a return spring. All the limiting rods are connected to the linkage frame plate. The linkage frame plate is slidably connected to the side wall of the storage frame along the height direction of the storage frame. One end of the return spring is connected to the storage frame, and the other end is connected to the linkage frame plate. The extension and retraction direction of the return spring is parallel to the height direction of the storage frame. One of the push plates has a pushing surface on its upper surface, and the lower surface of the linkage frame plate has a mating surface adapted to the pushing surface.

[0022] By adopting the above technical solution, when the push plate is driven by the drive component to move towards the storage frame, when the mating surface on the linkage frame plate comes into contact with the pushing surface, the linkage frame plate will drive all the limit rods to move upward under the pushing of the push plate, so that the limit rods are disengaged from the contact with the bottom building steel structure. At this time, the return spring is compressed. Correspondingly, when the push plate moves away from the storage frame to reset, so that the push plate and the linkage frame plate are disengaged from each other, the return spring will drive the linkage frame plate to move downward to reset, so that the limit rods are re-attached to the bottom building steel structure side wall.

[0023] Preferably, each limiting rod of the linkage frame is connected to a first telescopic member, and a second telescopic member is provided at the end of each limiting rod away from the linkage frame. The first telescopic member is used to adjust the distance between the limiting rod and the linkage frame, and the second telescopic member is used to adjust the length of the limiting rod.

[0024] By adopting the above technical solution, the first telescopic component is used to adjust the distance between the limiting rod and the linkage frame plate, so as to control the limiting rod to always be in contact with the side wall of the building steel structure according to the width of the building steel structure. That is, to control the building steel structure to always be in contact with the limiting rod and the inner wall of the storage frame, thereby improving applicability. The second telescopic component is used to adjust the length of the limiting rod, that is, to adjust the overall length of the limiting rod according to the height of each building steel structure, so that when the limiting rod moves up to the specified height under the drive of the third lifting component, the limiting rod can be completely detached from the bottom building steel structure. It can also be that when the limiting rod moves down to reset under the drive of the return spring, the lower end of the limiting rod can be in contact with the side wall of the bottom building steel structure, thereby limiting the bottom building steel structure.

[0025] Secondly, this application also provides a method for testing the strength of a building steel structure, comprising the following steps:

[0026] The steel structures to be inspected are stacked one by one in the storage frame along the height direction of the storage frame, and the control drive component drives the push plate to press against the side wall of the steel structure at the bottom of the storage frame.

[0027] The pressure data is obtained and displayed by detecting the reverse pressure exerted by the building steel structure on the push plate through the detection component.

[0028] The tested building steel structure is pushed out of the storage frame by the drive component, and then the push plate is reset by the drive component to complete the testing operation of the building steel structure.

[0029] After the push plate detaches from the storage frame, the remaining building steel structure inside the storage frame moves downward under its own weight; repeat the above steps to achieve batch testing of all building steel structures inside the storage frame.

[0030] In summary, this application includes at least one of the following beneficial technical effects:

[0031] 1. Multiple sets of storage frames for placing the steel structures to be tested are set on the testing platform, along with push plates adapted to the storage frames. A drive assembly moves the push plates to press against the steel structures. During this pressing action, a detection assembly detects and displays the reverse pressure exerted by the steel structures on the push plates. This allows for simultaneous strength testing of the steel structures at the bottom of all storage frames, improving testing efficiency.

[0032] 2. After the inspection is completed, the drive component moves the push plate away from the turntable to push the inspected building steel structure away from the storage frame and onto the unloading platform to achieve automatic unloading. Attached Figure Description

[0037] The following is in conjunction with the appendix Figure 1-3 This application will be described in further detail.

[0038] This application discloses a strength testing device for building steel structures. (Refer to...) Figure 1The building steel structure strength testing equipment includes a testing table 1, and a plurality of storage frames 2 are welded on the upper surface of the testing table 1. In this embodiment of the application, there are 4 storage frames 2. Each storage frame 2 contains a building steel structure 6 to be tested. Each storage frame 2 is equipped with a limiting rod 23, and the building steel structure 6 in the storage frame 2 is attached to the limiting rod 23 and the inner wall of the storage frame 2.

[0039] Reference Figure 1 and Figure 2 The testing platform 1 is also equipped with a third lifting component 24 for driving the limit rod 23 to rise and fall. The third lifting component 24 includes a linkage frame plate 241 and a return spring 242. The linkage frame plate 241 slides along the height direction of the storage frame 2 and is connected to the inner circle space enclosed by the four storage frames 2, and the peripheral wall of the linkage frame plate 241 is attached to the side wall of the storage frame 2. One end of the return spring 242 is welded to the linkage frame plate 241, and the other end is connected to the side wall of the storage frame 2. The extension and retraction direction of the return spring 242 is parallel to the height direction of the storage frame 2. A first telescopic component 25 is connected between the linkage frame plate 241 and each limit rod 23. The first telescopic component 25 includes a telescopic sleeve and a bolt for fixing the extension and retraction length of the telescopic sleeve. The extension and retraction direction of the first telescopic component 25 is parallel to the width direction of the storage frame 2, so as to adjust the distance between the limit rod 23 and the inner wall of the storage frame 2.

[0040] Reference Figure 2 Each limiting rod 23 is provided with a second telescopic member 26 at one end away from the linkage frame plate 241. The telescopic direction of the second telescopic member 26 is parallel to the length direction of the limiting rod 23, so as to adjust the length of the limiting rod 23. The second telescopic member 26 is also composed of a telescopic sleeve and bolts for fixing the telescopic sleeve's telescopic length.

[0041] Reference Figure 1 , Figure 2 and Figure 3 The upper surface of the testing table 1 is also slidably connected with several push plates 3, and a drive assembly 4 for driving all the push plates 3 to slide. The four storage frames 2 and the linkage frame plate 241 are all located around the push plates 3. The push plates 3 and the storage frames 2 are arranged one-to-one. Each storage frame 2 has a through hole 21 on its side wall facing the push plate 3, which allows the push plate 3 to be inserted into the storage frame 2. The drive assembly 4 is used to drive the push plate 3 to move towards or away from the corresponding storage frame 2. When the push plate 3 is close to the corresponding storage frame 2, it drives the push plate 3 to press against the building steel structure 6 at the bottom of the corresponding storage frame 2, so that the building steel structure 6 at the bottom of the storage frame 2 is clamped between the push plate 3 and the inner wall of the storage frame 2.

[0042] Reference Figure 1 and Figure 2The testing platform 1 is also equipped with a testing component 5, which includes a pressure sensor 51 embedded in the side wall of each push plate 3, a controller 52 electrically connected to all pressure sensors 51, and a display 53 electrically connected to the controller 52. Specifically, the controller 52 can be a PLC controller, and the display 53 can be a screen. The pressure sensor 51 is embedded in the side wall of the push plate 3 facing the corresponding storage frame 2, and the outer surface of the pressure sensor 51 is flush with the outer surface of the push plate 3. When the push plate 3 presses against the outer surface of the building steel structure 6, the pressure sensor 51 will detect the pressure. The reverse pressure applied by the building steel structure 6 to the push plate 3 is transmitted to the controller 52, which then transmits the pressure data to the display 53 for display. In addition, the controller 52 has pre-stored the communication address for each pressure sensor 51 and the position information of the corresponding storage frame 2 detected by each pressure sensor 51 (such as pre-numbering the storage frames 2 to display the pressure data of the building steel structure 6 in each storage frame 2 in the form of numbers). When displaying the pressure data, the corresponding position information of the detected storage frame 2 is displayed.

[0043] Reference Figure 2 and Figure 3 The drive assembly 4 specifically includes a turntable 41, a rotating component 42, several moving blocks 43, and a limiting plate 44. The turntable 41 is rotatably connected to the upper surface of the testing table 1. The rotating component 42 is used to drive the turntable 41 to rotate. Specifically, the rotating component 42 can be embedded in a motor on the upper surface of the testing table 1. By connecting the driving end of the rotating component 42 to the center of the turntable 41, the rotation drive of the turntable 41 is realized.

[0044] Reference Figure 1 and Figure 3 The movable block 43 and the push plate 3 are set one-to-one; the limiting plate 44 is welded to the upper surface of the detection table 1; the upper surface of the limiting plate 44 has a limiting groove 441, which is set one-to-one with the movable block 43 and is used for the corresponding movable block 43 to be inserted and slide along the length direction of the limiting groove 441. The sliding direction of the movable block 43 is parallel to the sliding direction of the corresponding push plate 3; the upper surface of the movable block 43 near the turntable 41 is rotatably connected to a rotating rod 431, and the upper surface of the turntable 41 has an arc-shaped groove 411 through which each rotating rod 431 is inserted; the other end of the movable block 43 is welded to the push plate 3; in the initial state, the position of the rotating rod 431 in the arc-shaped groove 411 is as follows. Figure 1 As shown, when the turntable 41 rotates counterclockwise, the rotating rod 431 slides along the arc direction of the arc groove 411, and drives the moving block 43 to move along the length direction of the limiting groove 441 under the limiting action of the limiting groove 441, so that the push plate 3 moves towards the corresponding storage frame 2 and inserts into the storage frame 2, thereby achieving the pressing of the push plate 3 against the building steel structure 6.

[0045] Reference Figure 2 and Figure 3 The push plate 3 has a pushing surface 32 on its end face near the storage frame 2, and the lower surface of the linkage frame plate 241 has a mating surface 2411 that matches the pushing surface 32. Before the push plate 3 moves, the pushing surface 32 is in contact with the mating surface 2411. When the push plate 3 moves toward the corresponding storage frame 2, the push plate 3 moves upward under the pushing action of the linkage frame plate 241, thereby driving the limiting rod 23 to move upward, so that the limiting rod 23 is separated from the surface of the building steel structure 6 at the bottom of the storage frame 2, so that the push plate 3 can press against the building steel structure 6.

[0046] Reference Figure 1 and Figure 2 The side wall of the storage frame 2 away from the push plate 3 has a material passage notch 22, which allows the push plate 3 to pass through the storage frame 2 and also allows a single building steel structure 6 to pass through. The drive assembly 4 also includes an unloading plate 45, an unloading platform 46, a first lifting component 47, and a second lifting component 48. The first lifting component 47 includes a lifting frame 471 and a lifting cylinder 472. The detection platform 1 has a cavity 11 inside, and the lifting cylinder 472 and the lifting frame 471 are both inserted into the cavity 11. The drive end of the cylinder 472 is connected to the side wall of the lifting frame 471. The lifting frame 471 slides along the height direction of the cavity 11 and is connected to the cavity 11. The upper end of the lifting frame 471 passes through the cavity 11 and is connected to all the unloading plates 45. The unloading plates 45 are inserted into the material passage notch 22 to cooperate with the first lifting component 47 to realize the opening and closing of the material passage notch 22. The lifting cylinder 472 can be electrically connected to the controller 52 so that the controller 52 can drive the lifting cylinder 472 to start.

[0047] Reference Figure 1 and Figure 2 The unloading platform 46 is inserted through the testing platform 1 and is located around the unloading plate 45. The unloading platform 46 is used to receive the building steel structure 6 pushed out by the push plate 3 from the material passage notch 22. The second lifting component 48 is used to drive the unloading platform 46 to slide along the height direction of the testing platform 1. The second lifting component 48 can be a combination structure of motor and screw. By threading one side of the unloading platform 46 to the screw, the motor drives the screw to rotate, thereby realizing the lifting of the unloading platform 46.

[0048] Reference Figure 1 and Figure 2An inventory detector 54 is installed on the inner wall of the storage frame 2. Specifically, the inventory detector 54 can be a photoelectric switch embedded in the inner wall of the storage frame 2. The inventory detector 54 is electrically connected to the controller 52. The inventory detector 54 is used to detect the inventory of the building steel structure 6 in the storage frame 2. Specifically, if the inventory of the building steel structure 6 in the storage frame 2 is greater than the preset quantity, the receiving end of the inventory detector 54 (i.e., the photoelectric switch) will not receive the photoelectric signal emitted by the transmitting end. If the inventory of the building steel structure 6 in the storage frame 2 is less than the preset quantity, the receiving end of the inventory detector 54 will receive the photoelectric signal emitted by the transmitting end. At this time, the inventory detector 54 will send a replenishment signal to the controller 52. When the controller 52 receives the replenishment signal, it will control the display 53 to display the preset replenishment information. The specific content of the replenishment information can be: insufficient inventory of building steel structure 6.

[0049] This application also discloses a method for testing the strength of building steel structures, including the following steps:

[0050] The steel structure 6 to be tested is stacked one by one in the storage frame 2 along the height direction of the storage frame 2, and the control drive component 4 drives the push plate 3 to press against the side wall of the steel structure 6 at the bottom of the storage frame 2.

[0051] The pressure data is obtained and displayed by detecting the reverse pressure applied by the building steel structure 6 to the push plate 3 through the detection component 5;

[0052] The building steel structure 6 that has completed the inspection is pushed out of the storage frame 2 by the drive component 4, and then the push plate 3 is reset by the drive component 4 to complete the inspection operation of the building steel structure 6.

[0053] After the push plate 3 is removed from the storage frame 2, the remaining building steel structure 6 in the storage frame 2 moves downward under its own weight; repeat the above steps to achieve batch inspection of all building steel structures 6 in the storage frame 2.

[0054] The implementation principle of the steel structure strength testing device of this application is as follows: the steel structure 6 to be tested is placed in the storage frame 2, so that the steel structure 6 is stacked one by one along the height direction of the storage frame 2; then the controller 52 controls the rotating component 42 to drive the turntable 41 to rotate at a specified angle and then pauses. The specified angle can be determined according to the width of the steel structure 6 to be tested, so that all the push plates 3 are inserted into the corresponding storage frame 2 and press against the outer surface of the steel structure 6. The pressure sensor 51 detects the reverse pressure applied by the steel structure 6 to the push plates 3, and the controller 52 controls the display screen to display the above pressure data.

[0055] After the push plate 3 presses against the building steel structure 6 for a specified time, the controller 52 first controls the first lifting component 47 to drive the unloading plate 45 to move down to open the material passage gap 22. Then, it controls the rotating component 42 to restart and drive the push plate 3 to continue moving away from the turntable 41. During this process, the push plate 3 pushes the building steel structure 6 that has been inspected at the bottom of the storage frame 2 to the upper surface of the unloading platform 46, and controls the push plate 3 to reset, then controls the unloading plate 45 to move up and reset. Finally, it controls the second lifting component 48 to drive the unloading platform 46 to move down to a specified height, which is the height of the building steel structure 6, to ensure that the upper surface of the unloading platform 46 is flush with the upper surface of the inspection platform 1, so that the building steel structure 6 that has been inspected can be stacked on top of the unloading platform 46.

[0056] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
