[0029] In order to solve the technical problems in the prior art, the present invention will be further described in conjunction with the accompanying drawings and embodiments:

[0030] like Figures 1 to 4As shown in the figure, this utility model discloses a concrete strength tester structure with a telescopic arm, including a sliding base 1, a lifting mechanism 2, a driving mechanism 3, and a fixed base 4. The lifting mechanism 2 is assembled on the sliding base 1 and is connected to a lifting platform 21. The driving mechanism 3 and the fixed assembly are respectively installed on the lifting platform 21.

The fixed base 4 is provided with a limiting groove at the end away from the positioning cylinder 51. The limiting shell 6 is slidably embedded in the limiting groove. The fixed shell 401 is in the limiting groove. 5. One end is connected to the positioning cylinder 51. The fixed shell 401 is in the limiting groove. The other end of 5 is provided with a rear cover 52. The positioning cylinder 51 and the rear cover 52 respectively abut against the fixed base 4. The rear cover 52 is provided with a through hole 521. The driving mechanism 3 is connected to the fixed rod 31 and drives the fixed rod 31 to extend and retract into the through hole 521 to contact the rebound spring.

[0031] In some embodiments, the drive mechanism 3 is provided with a fixed plate and a drive source 32, the drive source 32 is fixedly mounted on the fixed plate, and the output shaft of the drive source 32 is connected to the fixed rod 31.

[0032] The drive source 32 can be a hydraulic cylinder. The drive source 32 provides power to drive the fixed rod 31 to extend and retract in a reciprocating linear motion. When the fixed rod 31 extends, it causes the rebound hammer to impact the detection point located in the limiting groove 5 of the fixed shell 401, thus completing the concrete strength test.

[0033] The lifting mechanism 2 is used to move the lifting platform 21, its fixed base 4, rebound hammer and drive mechanism 3 to different heights to realize concrete strength testing at different height test points.

[0034] The fixed shell 401 has a limiting groove; 5 is provided with a contour groove 501 to adapt to the outer shell contour of the rebounder and ensure that the rebounder is stably fixed. The arc-shaped inner wall of the limiting shell 6 and the limiting groove 501 of the fixed shell 401 form an annular structure that adapts to the outer shell of the rebounder.

[0035] In some embodiments, the fixed shell 401 has a limiting groove; one end of the fixed shell 401 is provided with a fixed cylinder 53, the positioning cylinder 51 is detachably connected to the fixed cylinder 53, and the positioning cylinder 51 is provided with a cavity adapted to the head of the rebounder.

[0036] The fixing shell 401 can be positioned in the limiting groove 5 by the rear cover 52 and the positioning cylinder 51, thus limiting it to the fixing base 4. When installing the rebound spring, first remove the limiting shell 6 and the positioning cylinder 51, place the rebound spring into the contour groove 501, and then install the positioning cylinder 51 and the fixing cylinder 53 of the fixing shell 401 limiting groove 5 to complete the fixing of the rebound spring. In addition, by removing the positioning cylinder 51, different models of fixing shell 401 limiting groove 5 can be replaced.

The threaded rod 23 is rotatably inserted into the threaded sleeve 22, and the top end of the threaded rod 23 is fixedly connected to the lifting platform 21.

[0042] The rotating drive component 24 drives the threaded rod 23 to rotate. The threaded rod 23 is threadedly connected to the threaded sleeve 22, similar to the connection principle of a screw and a bolt. This drives the lifting platform 21 to move up and down, so that the drive mechanism 3 and the rebound hammer are at different heights, completing the concrete strength test at different height points.

[0043] Furthermore, a guide column 9 is provided between the fixed platform 82 and the lifting platform 21, and the extension and retraction direction of the guide column 9 is consistent with the extension and retraction direction of the lifting platform 21.
