Embodiment Construction

[0022] Below in conjunction with accompanying drawing and specific embodiment the present invention will be described in further detail:

[0023] The concrete resilience meter based on the flywheel component designed by the present invention includes a fixed disc 3, on which a flywheel device 2, a striking rod 13, a speed sensor 7 and a position sensor 8 are arranged, and the flywheel device 2 is connected by a rotating shaft 6 On the fixed disk 3, it is used to strike the striking rod. The striking rod 13 is wrapped in a striking rod sleeve with a smooth inner wall. The striking rod sleeve is connected to the fixed disk 3 by the lifting device 9. The lifting device 9 can The strike rod sleeve is lifted to the plane of the flywheel device, and the rotating shaft 6 is driven by the motor 4; The entire fixing device is arranged in the hammer shell 10, and the side wall of the shell 10 is perpendicular to the shell and is provided with a bullet barrel sleeve for placing the bulle...

Abstract

The invention discloses a concrete rebound instrument based on a flywheel element. The concrete rebound instrument comprises a fixing structure. The fixing structure is provided with a flywheel device, an impact rod, a speed sensor and a position sensor. The flywheel device is connected to the fixing structure through a rotating shaft and is used for impacting the impact rod. The impact rod is used for impacting a bouncing rod, an impact rod sleeve with a smooth inner wall is internally wrapped with the impact rod, the impact rod sleeve is connected to the fixing structure through a lifting device, the lifting device can lift the impact rod sleeve to the plane of the flywheel device, and the rotating shaft is driven by a motor. A pointer is arranged on the flywheel device, and a dial corresponding to the pointer is arranged on the fixing structure. The concrete rebound instrument has the advantages of small size, easy and convenient operation and high stability. According to the concrete rebound instrument based on the flywheel element, when the strength of concrete is tested, the bouncing rod is perpendicular to a concrete element under test, the size of excitation force can be changed and other advantages are achieved.

Description

technical field [0001] The patent of the present invention relates to the technical field of concrete strength testing instruments, in particular to a novel concrete rebound instrument based on a flywheel component. [0002] technical background [0003] Concrete rebound tester is an instrument used to test the strength of general building components, bridges and various concrete components (slabs, beams, columns, bridges). However, the existing concrete hammer is held by the operator, and the external force is manually applied, and the energy storage of the spring is activated, which has many inconveniences. [0004] Most of the existing patents on concrete rebound hammers are supplemented by external support facilities without changing the spring energy storage structure of the hammer hammer to improve the accuracy and operability of the measurement. Contents of the invention [0005] The object of the present invention is to overcome the above-mentioned defects, and pro...
