Description

Technical Field

[0001] This invention relates to the field of concrete strength testing technology, specifically to a strength testing device for precast concrete components used in building construction. Background Technology

[0002] In the 1980s, my country began using concrete to produce cast-in-place and precast concrete components, including exterior and interior wall panels, that combined thermal insulation with structural requirements. Precast concrete components, with their advantages of standardized production, high construction efficiency, and controllable quality, have become a key material in modern construction engineering. During the production of precast concrete components, concrete test blocks need to be made. The strength of these test blocks is tested using concrete strength testing equipment to ensure that the concrete used to make the precast components meets the strength requirements.

[0003] Existing concrete strength testing equipment involves manually placing the test blocks on a support plate and testing their strength by compressing them. However, when placing the test blocks manually, it is difficult to accurately position them in the center of the support plate; the blocks may even be placed at the edge. If the test blocks are placed at the edge, the pressure transmission direction will deviate from the geometric axis of the test blocks, resulting in an eccentric compression state. In this case, the stress distribution inside the test blocks is uneven, with stress concentration in some areas and insufficient stress in others, ultimately causing premature failure of the test blocks. This leads to inaccurate test data and reduces data reliability. Summary of the Invention

[0004] The purpose of this invention is to provide a strength testing device for precast concrete components used in building construction, so as to solve the problems mentioned in the background art.

The folding mechanism includes an arc-shaped gear ring that is mounted on the bottom surface of the T-shaped block via a mounting column. A gear is meshed with the outer wall of the arc-shaped gear ring, and an L-shaped strip is provided on one side of the gear. The protective mechanism is located above the base and includes a movable sleeve that is slidably mounted on the outer wall of the support rod. A protective plate is fixedly mounted on the outer wall of the movable sleeve.

[0006] Preferably, a connecting frame is installed at the lower end of the screw, the bottom surface of the connecting frame is fixedly connected to the top surface of the abutment plate, and a T-shaped groove is opened on the bottom surface of the fixing strip, with the inner wall of the T-shaped groove slidingly connected to the outer wall of the T-shaped block.

[0007] Preferably, the side of the T-shaped block is hinged to the inner wall of the fixed frame, one end of the fixed frame has a groove, the inner wall of the groove is hinged to one end of the arc frame, one side of the arc frame abuts against one side of the inner wall of the groove, the side of the arc frame is fixedly connected to the side of the adjusting plate, and elastic elements are fixedly installed on the side of the fixed frame and the side of the arc frame.

[0008] Preferably, the inner wall of the T-shaped groove has a through groove, the top surface of the T-shaped block is fixedly installed with an adjusting column, the outer wall of the abutment plate is rotatably installed with a rotating frame through a bearing seat, the top surface of the rotating frame has an arc groove, and the inner wall of the arc groove and the inner wall of the through groove are slidably connected with the outer wall of the adjusting column.

[0009] Preferably, an adjusting block is fixedly installed on the top surface of the rotating frame, and an adjusting groove is opened on the side of the adjusting block. A support frame is fixedly installed on the top surface of the abutment plate, and an electric push rod is fixedly installed on the support frame. A fixed column is fixedly installed at one end of the electric push rod, and the outer wall of the fixed column is slidably connected to the inner wall of the adjusting groove.

[0010] Preferably, a concave frame is fixedly installed on the inner wall of the fixed frame, and a servo motor is fixedly installed on the inner wall of the concave frame. One end of the output rod of the servo motor rotates through the inner wall of the concave frame and is fixedly connected to the inner wall of the gear.

[0011] Preferably, a mounting plate is fixedly installed on the side of the fixing strip, and a limiting groove is opened on the side of the mounting plate. The limiting groove is composed of a horizontal groove and an arc-shaped groove. A limiting post is fixedly installed on the side of the fixing frame, and the outer wall of the limiting post is slidably connected to the inner wall of the limiting groove.

[0012] Preferably, an adjusting rod is fixedly installed on the side of the arc-shaped frame, one end of the L-shaped strip is fixedly connected to the side of the mounting plate, and the outer wall of the adjusting rod is slidably connected to the side of the L-shaped strip.

[0013] Preferably, a fixing sleeve is fixedly installed on the outer wall of the support rod, the lower end of the movable sleeve abuts against the top surface of the fixing sleeve, and an opening is provided through the outer wall of the side of the protective plate, with a fixing plate fixedly installed on the inner wall of the upper end of the opening.

[0014] Preferably, a push bar is fixedly installed on the side of the fixed frame, and the outer wall of one end of the push bar is slidably connected to the bottom surface of the fixed plate.

[0015] Compared with the prior art, the beneficial effects of the present invention are: This invention activates an electric push rod, which moves a fixed column. The fixed column then rotates an adjusting block and a rotating frame by a certain angle. The arc groove on the rotating frame moves the adjusting column and a T-shaped block. The T-shaped block moves the fixed frame and the arc frame. The arc frame moves the adjusting plates. The four adjusting plates move from four directions toward the center, squeezing and pushing the test block to the center position of the lifting assembly. When the lifting assembly squeezes and tests the test block, the internal stress distribution of the test block is more uniform, ensuring more accurate test data and improving data reliability. By activating the servo motor, the gear rotates on the outer wall of the arc-shaped gear ring, which in turn rotates the concave frame and the fixed frame. The fixed frame then rotates the arc-shaped frame and the adjusting plate. Simultaneously, the arc-shaped frame rotates the adjusting rod. When the adjusting rod rotates to the L-shaped bar, the L-shaped bar blocks the adjusting rod. The adjusting rod then rotates the arc-shaped frame and the adjusting plate in the opposite direction relative to the fixed frame and folds upward. When the test block is placed on the lifting assembly, the adjusting plate will not obstruct the test block, allowing for convenient and quick placement and retrieval of the test block, thereby improving work efficiency. When the fixed frame rotates at a certain angle, it drives the push bar to rotate at a certain angle. The push bar pushes the fixed plate upward, and the fixed plate drives the protective plate upward. At this time, the protective cover opens, which can facilitate the placement and opening of the test block. When the fixed frame rotates in the opposite direction at a certain angle, it drives the push bar to reverse. At this time, the push bar moves away from the fixed plate. Under the gravity of the protective plate, the protective plate drives the moving sleeve to move downward. When the moving sleeve contacts the fixed sleeve, the protective plate stops moving. At this time, the protective plate blocks the test block from all sides. When the test block breaks and splashes during testing, the protective plate blocks the splashing debris, which is less likely to injure the staff and ensures the safety of the staff.

[0018] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. This application will now be described in detail with reference to the accompanying drawings and embodiments.

[0019] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present application, and not all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative effort should fall within the scope of protection of the present application.

[0020] like Figures 1-9 As shown, this application provides a strength testing device for precast concrete components used in building construction, including: a base 1, a support plate 102 fixedly installed on the top surface of the base 1 by a support rod 101, a lifting assembly 103 installed on the top of the base 1, an abutment plate 106 provided above the lifting assembly 103, a screw rod 104 threaded through the top surface of the support plate 102, a control cabinet 107 provided on one side of the base 1, and further including: Adjustment mechanism 2 is located above base 1. Adjustment mechanism 2 includes four fixing strips 201 fixedly installed on the outer wall of abutment plate 106. T-shaped block 203 and fixing frame 204 are provided below fixing strips 201. Arc frame 206 and adjustment plate 207 are provided below fixing frame 204. Specifically, such as Figures 1-9 As shown, a connecting frame 105 is installed at the lower end of the screw 104. The bottom surface of the connecting frame 105 is fixedly connected to the top surface of the abutment plate 106. A T-shaped groove 202 is opened on the bottom surface of the fixing strip 201. The inner wall of the T-shaped groove 202 is slidably connected to the outer wall of the T-shaped block 203.

[0021] In this embodiment: the top of the test block is abutted by the abutment plate 106, and the T-shaped groove 202 limits the T-shaped block 203, so that the T-shaped block 203 moves more stably.

[0022] Specifically, such as Figures 1-9 As shown, the side of the T-shaped block 203 is hinged to the inner wall of the fixed frame 204. One end of the fixed frame 204 has a groove 205. The inner wall of the groove 205 is hinged to one end of the arc frame 206. One side of the arc frame 206 abuts against one side of the inner wall of the groove 205. The side of the arc frame 206 is fixedly connected to the side of the adjusting plate 207. Elastic members 208 are fixedly installed on the side of the fixed frame 204 and the side of the arc frame 206.

[0023] In this embodiment: the elastic element 208 applies elastic force to the arc frame 206. When the T-block 203 moves, it drives the fixed frame 204 and the arc frame 206 to move. The arc frame 206 drives the adjusting plate 207 to push the test block to the middle part of the lifting assembly 103 to ensure the accuracy of the test. One side of the arc frame 206 abuts against the inner wall of one side of the tank 205 to limit the rotation angle of the arc frame 206.

[0024] Specifically, such as Figures 1-9 As shown, the inner wall of the T-shaped groove 202 is provided with a through groove 209, the top surface of the T-shaped block 203 is fixedly installed with an adjusting column 210, the outer wall of the abutment plate 106 is rotatably installed with a rotating frame 211 through a bearing seat, the top surface of the rotating frame 211 is provided with an arc groove 212, and the inner wall of the arc groove 212 and the inner wall of the through groove 209 are slidably connected with the outer wall of the adjusting column 210.

[0025] In this embodiment: when the rotating frame 211 rotates, the arc groove 212 on the rotating frame 211 drives the adjusting column 210 to move, the adjusting column 210 drives the T-shaped block 203 to move, and further drives the adjusting plate 207 to move, thereby adjusting the position of the adjusting plate 207.

[0026] Specifically, such as Figures 1-9As shown, an adjusting block 213 is fixedly installed on the top surface of the rotating frame 211, and an adjusting groove 214 is opened on the side of the adjusting block 213. A support frame 216 is fixedly installed on the top surface of the abutment plate 106, and an electric push rod 215 is fixedly installed on the support frame 216. A fixing column 217 is fixedly installed at one end of the electric push rod 215, and the outer wall of the fixing column 217 is slidably connected to the inner wall of the adjusting groove 214.

[0027] In this embodiment: the electric push rod 215 drives the fixed column 217 to move, and the fixed column 217 moves and cooperates with the adjustment groove 214, thereby driving the adjustment block 213 and the rotating frame 211 to rotate at a certain angle.

[0028] Folding mechanism 3 is located above base 1. Folding mechanism 3 includes an arc-shaped gear ring 305 mounted on the bottom surface of T-shaped block 203 via mounting column 304. Gear 303 is meshed with the outer wall of arc-shaped gear ring 305. L-shaped strip 307 is provided on one side of gear 303. Specifically, such as Figures 1-9 As shown, a concave frame 301 is fixedly installed on the inner wall of the fixed frame 204, and a servo motor 302 is fixedly installed on the inner wall of the concave frame 301. One end of the output rod of the servo motor 302 rotates through the inner wall of the concave frame 301 and is fixedly connected to the inner wall of the gear 303.

[0029] In this embodiment: the servo motor 302 is fixed by the concave frame 301. The servo motor 302 has a self-locking function. The servo motor 302 drives the gear 303 to rotate on the outer wall of the arc-shaped gear ring 305, which in turn drives the fixing frame 204, the arc frame 206 and the adjusting plate 207 to rotate at a certain angle.

[0030] Specifically, such as Figures 1-9 As shown, a mounting plate 308 is fixedly installed on the side of the fixing strip 201. A limiting groove 309 is opened on the side of the mounting plate 308. The limiting groove 309 is composed of a horizontal groove and an arc-shaped groove. A limiting post 310 is fixedly installed on the side of the fixing frame 204. The outer wall of the limiting post 310 is slidably connected to the inner wall of the limiting groove 309.

[0031] In this embodiment, the limiting groove 309 limits the limiting post 310 and the fixing frame 204, making the movement of the fixing frame 204 more stable.

[0032] Specifically, such as Figures 1-9 As shown, an adjusting rod 306 is fixedly installed on the side of the arc-shaped frame 206, one end of the L-shaped strip 307 is fixedly connected to the side of the mounting plate 308, and the outer wall of the adjusting rod 306 is slidably connected to the side of the L-shaped strip 307.

[0033] In this embodiment: the L-shaped strip 307 blocks the adjusting rod 306. When the fixed frame 204 rotates to one side, the adjusting rod 306 is blocked by the L-shaped strip 307, which causes the arc frame 206 and the adjusting plate 207 to rotate in the opposite direction relative to the fixed frame 204 and fold upward.

[0034] The protective mechanism 4 is located above the base 1. The protective mechanism 4 includes a movable sleeve 403 that is slidably installed on the outer wall of the support rod 101. A protective plate 404 is fixedly installed on the outer wall of the movable sleeve 403.

[0035] Specifically, such as Figures 1-9 As shown, a fixed sleeve 402 is fixedly installed on the outer wall of the support rod 101, the lower end of the movable sleeve 403 abuts against the top surface of the fixed sleeve 402, and a through opening 405 is opened through the outer wall of the side of the protective plate 404. A fixed plate 406 is fixedly installed on the inner wall of the upper end of the through opening 405.

[0036] In this embodiment, the protective plate 404 is used to block the debris that splashes during the test block testing process, preventing the debris from injuring the staff and ensuring their safety.

[0037] Specifically, such as Figures 1-9 As shown, a push bar 401 is fixedly installed on the side of the fixed frame 204, and the outer wall of one end of the push bar 401 is slidably connected to the bottom surface of the fixed plate 406.

[0038] In this embodiment: When the fixed frame 204 rotates and the adjusting plate 207 is folded, the fixed frame 204 drives the push bar 401 to push the fixed plate 406 upward, and the fixed plate 406 drives the protective plate 404 upward. At this time, the protective plate 404 is opened, which makes it easier to pick up and place the test block.

[0039] The specific steps are as follows: In the initial state, the protective plate 404 is open and the adjusting plate 207 is folded. At this time, the concrete test block is placed on the lifting assembly 103. The screw 104 is rotated, which moves the connecting frame 105 and the abutment plate 106, so that the bottom surface of the abutment plate 106 makes slight contact with the top surface of the test block. The servo motor 302 is turned on, which drives the gear 303 to rotate a certain angle on the outer wall of the arc-shaped gear ring 305, which in turn drives the fixed frame 204, the arc-shaped frame 206 and the adjusting plate 207 to rotate a certain angle. The elastic element 208 pushes the arc-shaped frame 206 to rotate a certain angle relative to the fixed frame 204. At this time, the arc-shaped frame 206 drives the adjusting plate 207 to be in a vertical position. In this state, the fixed frame 204 drives the push bar 401 away from the fixed plate 406. Under the gravity of the protective plate 404, the protective plate 404 drives the moving sleeve 403 to move downward. When the moving sleeve 403 contacts the fixed sleeve 402, the protective plate 404 stops moving. At this time, the protective plate 404 blocks the test block from all sides. The electric push rod 215 is activated, which drives the fixed column 217 to move. The fixed column 217 drives the adjusting block 213 and the rotating frame 211 to rotate at a certain angle. The arc groove 212 on the rotating frame 211 drives the adjusting column 210 and the T-block 203 to move. The T-block 203 drives the fixed frame 204 and the arc frame 206 to move. The arc-shaped frame 206 drives the adjusting plate 207 to move. The four adjusting plates 207 move from four directions towards the center, squeezing and pushing the test block. The test block is moved to the middle position of the lifting assembly 103. The electric push rod 215 is activated, which drives the fixed column 217 to move in the opposite direction. After the adjusting plate 207 moves away from the test block, the lifting assembly 103 is adjusted by the control cabinet 107 to push the test block upward to test the strength of the test block. The protective plate 404 blocks the debris of the test block. After the test is completed, the servo motor 302 is activated, which drives the concave frame 301 and the fixed frame 204 to rotate. The fixed frame 204 drives the arc-shaped frame 206 to rotate. The arc frame 206 and the adjusting plate 207 rotate, and at the same time, the arc frame 206 drives the adjusting rod 306 to rotate. When the adjusting rod 306 rotates to the L-shaped strip 307, the L-shaped strip 307 blocks the adjusting rod 306. The adjusting rod 306 drives the arc frame 206 and the adjusting plate 207 to rotate in the opposite direction to the fixed frame 204 and fold upward. The fixed frame 204 drives the push bar 401 to rotate at a certain angle. The push bar 401 pushes the fixed plate 406 to move upward. The fixed plate 406 drives the protective plate 404 to move upward. At this time, the protective plate 404 opens. Rotate the screw 104 to drive the connecting frame 105 and the abutment plate 106 to move upward, and the test block can be taken out.
