Technical Field

[0001] This utility model relates to the field of concrete block testing technology, specifically a strength testing device for prefabricated concrete blocks. Background Technology

[0002] Concrete blocks have advantages such as high strength, lightweight, good thermal insulation, and good fire resistance, and are therefore widely used in building structures. Their prefabricated nature can improve construction efficiency and reduce labor and time costs. After the prefabricated concrete blocks are formed, their strength needs to be tested to ensure their safety in use.

[0003] Traditional concrete block testing devices can only detect the overall strength of concrete blocks and cannot test the strength of concrete blocks at different angles and positions. This reduces the diversity of concrete block testing, resulting in reduced testing effectiveness and incomplete strength testing of concrete blocks, which urgently needs to be improved. Utility Model Content

[0004] The purpose of this invention is to provide a strength testing device for prefabricated concrete blocks to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a strength testing device for prefabricated concrete blocks, comprising a placement seat, a telescopic cylinder 1, a ball block 1, and a ball block 2. The placement seat is symmetrically equipped with telescopic cylinder 1, and an adjusting plate is hinged to the upper ends of the two telescopic cylinder 1s. A ball block 1 is connected to the middle of the bottom of the adjusting plate. A matching limiting seat 1 is slidably mounted below the ball block. The bottom of the limiting seat 1 is fixed to the placement seat. A limiting seat 2 is connected to the middle of the top of the adjusting plate. A matching ball block 2 is slidably mounted on the limiting seat 2. A placement platform is connected to the top of the ball block 2. Telescopic cylinder 2s are hinged to the front and rear sides of the bottom of the placement platform. The bottoms of the two telescopic cylinder 2s are fixed to the front and rear ends of the upper surface of the adjusting plate.

[0007] Preferably, a transmission rod is connected to the middle of the placement platform, and the front end of the transmission rod extends to the front side of the placement platform and is equipped with a motor.

[0008] Preferably, an active tapered ruler is fitted on the outside of the transmission rod, and driven gears are symmetrically meshed on the rear side of the active tapered ruler. Each of the two driven gears is connected to a threaded rod, and one end of the threaded rod is connected to the inner side of the placement platform.

[0009] Preferably, a movable cylinder is fitted around the threaded rod, a clamp is connected to one side of the movable cylinder, the clamp passes through the clearance groove and extends to the top of the placement seat, and a limit slider is connected to the bottom of the movable cylinder.

[0010] Preferably, the bottom of the placement platform is symmetrically connected with limiting grooves that match the limiting slider.

[0011] Preferably, a bracket is connected to the top of one side of the placement seat, a top frame is connected to the top of one side of the bracket, and a control panel is installed on the side where the bracket connects to the placement seat.

[0012] Preferably, a screw is connected to the bottom of the top frame, a motor is installed at one end of the screw, a moving block is fitted around the outside of the screw, a guide rod passes through the top of the moving block and is positioned above the screw, a lifting cylinder is installed inside the moving block, and a pressure plate is connected to the bottom of the lifting cylinder.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] (1) The strength testing device for this type of prefabricated concrete block allows the placement platform to rotate in the front and rear lateral directions by rotating the ball block two along the inner limit seat two and cooperating with the telescopic drive of the telescopic cylinder two. The placement platform and the adjustment plate can rotate in the left and right lateral directions by rotating the ball block one along the inner limit seat one and cooperating with the telescopic drive of the telescopic cylinder one. This is used to change the angle of subsequent pressure strength testing of the concrete block, improve the diversity of concrete block testing, thereby improve the testing effect and make the concrete block strength testing more complete.

[0015] (2) The strength testing device for this type of prefabricated concrete block, through the setting and cooperation of guide rod, screw rod, top frame, moving block and motor, is used to move the moving block and change the specific position of the pressure plate on the concrete block to be tested, thereby further improving the comprehensiveness and efficiency of the device for testing the strength of concrete blocks.

[0016] (3) The strength testing device for this type of prefabricated concrete block, through the setting and cooperation of the active tapered ruler, the transmission rod and the motor, can drive the two driven gears in the meshing state to rotate synchronously. With the help of the limiting slider sliding along the limiting groove, the auxiliary moving cylinder can be limited to move back and forth along the threaded rod in a straight line. This makes it easy to adjust the distance between the two clamping plates according to the specifications of the concrete block, which is convenient for fixing the concrete block and improving the stability of subsequent strength testing. The setting of the support block reduces the contact area with the bottom of the concrete block, avoids errors in the test results due to clamping, and reduces the impact on the concrete block test.

[0024] The top of the second ball block 23 is connected to a placement platform 6. The top of the placement platform 6 is symmetrically connected to a relief groove 5. The upper surface of the placement platform 6 is symmetrically connected to a support block 14. The setting of the support block 14 reduces the contact area with the bottom of the concrete block, avoids errors in the test results due to clamping, and reduces the impact on the test of the concrete block.

[0025] Telescopic cylinders 29 are hinged to the front and rear sides of the bottom of the placement platform 6, and the bottoms of the two telescopic cylinders 29 are fixed to the front and rear ends of the upper surface of the adjustment plate 25.

The active tapered ruler 15, the transmission rod 27 and the motor 28 are set up and used in conjunction to drive the two driven gears 16 that are meshed with it to rotate synchronously. With the help of the limiting slider 20 sliding along the limiting groove 18, the auxiliary moving cylinder 26 can be limited to move back and forth along the threaded rod 17 in a straight line. This makes it easy to adjust the distance between the two clamping plates 4 according to the specifications of the concrete block, which is convenient for fixing the concrete block and improving the stability of subsequent strength testing.

[0027] The rear side of the active tapered ruler 15 is symmetrically meshed with driven gears 16. Both driven gears 16 are connected to threaded rods 17.

[0032] A guide rod 2 runs through the top of the movable block 8. The guide rod 2 is positioned above the screw 3. A lifting cylinder 11 is installed inside the movable block 8. A pressure plate 12 is connected to the bottom of the lifting cylinder 11.

[0033] A control panel 13 is installed on one side of the connection between the bracket 10 and the placement base 1.

[0034] In this embodiment, the active tapered ruler 15, transmission rod 27, and motor 28 are configured and used in conjunction to drive the two driven gears 16 in a meshing state to rotate synchronously. The limiting slider 20, guided by the limiting groove 18, limits the linear movement of the auxiliary moving cylinder 26 along the threaded rod 17, facilitating adjustment of the distance between the two clamping plates 4 according to the specifications of the concrete block, thus facilitating the fixing of the concrete block. The rotation of the ball block 23 within the limiting seat 24, combined with the telescopic drive of the telescopic cylinder 29, allows the placement platform 6 to rotate in the front and rear lateral directions. The rotation of the ball block 22 within the limiting seat 21, combined with the telescopic drive of the telescopic cylinder 19, allows the placement platform 6 and the adjusting plate 25 to rotate in the left and right lateral directions, changing the angle for subsequent pressure strength testing of the concrete block. The guide rod 2, screw 3, top frame 7, moving block 8, and motor 9 are configured and used to move the moving block 8, changing the specific position of the pressure plate 12 on the concrete block to be tested.
