[0040] As a preferred embodiment, the outer edge of the support platform 2 is upwardly turned to form a baffle 22. The baffle 22 is arranged in a circle along the circumferential direction of the support platform 2. The baffle can prevent the test mold from slipping off the support platform during the vibrating process. The baffle and the support platform form a containing groove. The containing groove is used for placing the test mold.

[0041] The manual driving structure 3 includes a transmission shaft 31, an eccentric shaft, and a hinged arm 33.

[0042] Specifically, the transmission shaft 31 is rotatably installed in the support box 1. One end of the transmission shaft 31 is connected with the eccentric shaft. The lower end of the jacking push rod 11 is hingedly connected with the hinged arm 33. The other end of the hinged arm 33 is rotatably connected with the eccentric shaft.

[0043] Referring to Fig. 1 , the lower end of the jacking push rod 11 is formed with two ear plates 111. The two ear plates 111 are oppositely arranged. The upper end of the hinged arm 33 is rotatably connected with a hinged shaft. The hinged shaft is connected between the two ear plates 111.

[0050] In the outdoor power shortage operation condition, the test mold is placed on the bearing platform. The construction personnel rotates the driving gear by the hand wheel. The driving gear drives the driven gear to rotate the transmission shaft.

[0051] After the transmission shaft 31 is manually rotated, the hinged arm 33 reciprocatingly pushes and pulls the jacking push rod 11 up and down to make the bearing platform 2 vibrate, and then the concrete in the test mold is vibrated by the vibration of the bearing platform 2. After the transmission shaft is rotated, since the size and weight of the energy storage flywheel are far greater than those of the left and right wheel discs, the rotational potential energy of the energy storage flywheel is used to continue driving the transmission shaft to rotate to continuously and labor-savingly make the bearing platform vibrate.

[0052] The manual portable concrete test block vibrating table of the present application realizes speed increase by manually driving the transmission shaft by the construction personnel, realizes power storage by driving the energy storage flywheel, ensures smooth movement, converts rotation into power for reciprocating movement of the jacking push rod up and down by the eccentric shaft and the hinged arm, and realizes the vibration of the bearing platform up and down by the elastic member to realize the vibration of the concrete in the test mold.
