At the same time, the two sets of positioning rods 104 position the box beam 601. Then, the No. 2 electric hydraulic cylinder 409 is shortened to place the box beam 601 on the two sets of placement platforms 103. The box beam 601 pushes the baffle 509 backward, so that the circular hole 510 moves backward. The photoelectric signal emitted by the photoelectric signal transmitter 503 passes through the circular hole 510 and is received by the photoelectric signal receiver 504, so that the warning light 105 flashes and the No. 1 electric cylinder is started. The dynamic hydraulic cylinder 107 is extended, and when the box beam 601 is flipped away, the movable plate 507 moves the baffle 509 forward under the action of the elastic force of the spring 511, so that the baffle 509 again isolates the photoelectric signal of the photoelectric signal transmitter 503. When the box beam 601 is placed on the placement table 103, the No. 2 electric hydraulic cylinder 409 is operated to extend, so that the top fixing end 411 on the flip arm 405 is perpendicular to the horizontal plane, and the electric control trolley 302 is operated to move backward, so that the flip arm 405 fixes the front end of the box beam 601 through the top fixing end 411, thereby completing the fixation of the box beam 601.

[0046] In a ship box beam strength testing device of the present invention, the top of the flip arm 405 is slightly lower than the top of the guide roller 203. The control cabinet 102, the loading head 108, the pressure sensor, the motor 204, the electric control trolley 302, the No. 2 electric hydraulic cylinder 409, the photoelectric signal transmitter 503 and the photoelectric signal receiver 504 of the ship box beam strength testing device of the present invention are purchased on the market. The technicians in the industry only need to install and operate it according to the accompanying instruction manual, without the need for the technicians in this field to make creative labor.

[0047] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the technical principles of the present invention. These improvements and modifications should also be regarded as the scope of protection of the present invention.
