Abstract
Description
Technical Field
[0001] This utility model relates to the field of brick testing technology, and in particular to a brick strength testing device. Background Technology
[0002] Bricks are one of the most commonly used materials in engineering construction. Most common bricks are sintered bricks. In order to ensure the strength of the building, the bricks need to be sampled for strength testing. Currently, there are two common methods for testing the strength of sintered bricks. One is to test the density of the bricks by rebound testing, which is often used in the research and development of new bricks. The other is to impact the bricks to directly see the strength of the finished sintered bricks.
[0003] CN218470428U discloses a brick strength testing device, including a base and a mounting frame set on the top of the base. A telescopic cylinder is set on the top of the mounting frame, and an impact head is set inside the mounting frame. A placement box is set on the top of the base, and a lifting plate is set inside the mounting frame. The impact head is fixedly installed at the bottom of the lifting plate, and a box is fixedly installed on the top of the lifting plate. A connecting frame is set above the box. The output shaft of the telescopic cylinder extends into the mounting frame and is fixedly connected to the top of the connecting frame. Two clamping boxes are fixedly installed at the bottom of the connecting frame, and two top plates are fixedly installed on the top of the lifting plate.
[0004] As shown in the prior art, the detection device can perform two types of detection on bricks, with diverse detection methods and good detection results. However, when performing impact force detection, the falling structure needs to be manually unlocked by the user before falling and manually moved and reset by the user after falling. In addition, the structure may bounce to other places during the fall, making the operation of this function relatively troublesome and the safety poor. Therefore, we propose a brick strength detection device. Utility Model Content

The three fixed plates 11 are located on one side of the left fixed plate 11. The rotating shaft 13 is rotatably installed on the inner side of the fixed plate 11. One end of the rotating shaft 13 is fixedly connected to the output end of the motor 12. The winches 14 are fixedly installed on the left and right sides of the outer side of the rotating shaft 13. The winches 14 are used to fix the connecting rope 15. The guide wheel 16 is used to change the winding direction of the connecting rope 15. The connecting rope 15 is wound on the outer side of the winch 14. One end of the connecting rope 15 is fixedly connected to the top of the fixed plate 8. The guide wheel 16 is fixedly installed on the top left and right sides of the lifting seat 5.
[0027] In this embodiment, the counterweight 7 is made of iron material and is a cylinder. The counterweight 7 is used to contact the brick for strength testing.
[0028] In this embodiment, the guide sleeve 10 and the connecting rod 9 are coaxially arranged, and the guide sleeve 10 and the connecting rod 9 are in clearance fit. The clearance fit can reduce the sliding resistance and increase the falling speed of the counterweight 7.

The specific operation is as follows: First, the device is connected to an external power source. When a drop test is required, the controller first controls the motor 12 to work, which drives the winch 14 to rotate through the shaft 13, so that the connecting rope 15 is in a slack state. At this time, the electromagnet 6 is energized, and the counterweight 7 cannot fall due to the magnetic force. Then, the controller controls the electromagnet 6 to be de-energized. When its magnetism disappears, the counterweight 7 falls naturally. The fixed plate 8 drives the connecting rod 9 to move in the guide sleeve 10, and at the same time pulls the connecting rope 15 down until it hits the brick. When resetting is required, the controller controls the electromagnet 6 to be energized, and at the same time controls the output shaft of the motor 12 to rotate in the opposite direction, and pulls the counterweight 7 to reset through the connecting rope 15.
