[0021] Embodiment 1:

[0022] Figure 1-Figure 5 The utility model shows a hydraulic module flatbed self-propelled static load test device provided by the utility model, comprising a hydraulic flatbed self-propelled vehicle 1, the hydraulic flatbed self-propelled vehicle 1 comprising a carrier plate 11 and wheels for walking, the upper end surface of the carrier plate 11 is used to place a counterweight for static load testing, a static load test device 12 is connected to the middle of the carrier plate 11, and a support adjustment mechanism is connected to the lower end of the outer edge of the carrier plate 11 for adjusting the height of the carrier plate 11, the support adjustment mechanism comprises a first hydraulic cylinder 2 and a support frame 3, the first hydraulic cylinder 2 is fixed on the carrier plate 11, the support frame 3 is connected to the output end of the first hydraulic cylinder 2 and can move up and down, when the support frame 3 is controlled by the first hydraulic cylinder 2 to move downward, it will reversely lift the carrier plate 11 up until the wheels of the hydraulic flatbed self-propelled vehicle 1 are suspended, at this time the entire hydraulic flatbed self-propelled vehicle 1 is supported and fixed at a designated location by the support frame 3, the staff can start the static load test device 12 for testing and obtaining data, or install the static load test device 12 for testing when the entire device is fixed, and the counterweight for the test does not need to be repeatedly loaded and unloaded, and can be placed on the carrier plate 11 all the time.

[0023] The support frame 3 includes a support rod 31 and a support plate 32. The first hydraulic cylinder 2 and the support rod 31 are both connected to a torque arm 4. The two torque arms 4 are hinged at one end away from the first hydraulic cylinder 2 and the first hydraulic rod. The torque arm 4 is mainly used to prevent the support rod 31 from rotating relative to the first hydraulic cylinder 2.

[0024] The support adjustment mechanism also includes a second hydraulic cylinder 5, which is arranged horizontally, and the output end of the second hydraulic cylinder 5 faces the first hydraulic cylinder 2. The output end of the second hydraulic cylinder 5 is connected to a second hydraulic rod 51, and a connecting rod 52 is hinged on the second hydraulic rod 51. The end of the connecting rod 52 away from the second hydraulic rod 51 is hinged to the torque arm 4. When the first hydraulic cylinder 2 starts to control the support frame 3 to descend, the second hydraulic rod 51 is slowly extended out of the second hydraulic cylinder 5 under traction. After the wheels of the hydraulic flatbed self-propelled vehicle 1 are suspended in the air, the second hydraulic cylinder 5 can be started to control the second hydraulic rod 51 to move in the direction of the first hydraulic cylinder 2. The connecting rod 52 can apply an inclined downward force to the torque arm 4, indirectly providing support force to the support frame 3. The distance between the upper end of the connecting rod 52 and the axis of the first hydraulic cylinder 2 should be greater than the distance between the lower end of the connecting rod 52 and the axis of the first hydraulic cylinder 2, to ensure that the support system composed of the second hydraulic cylinder 5, the second hydraulic rod 51 and the connecting rod 52 operates normally.

[0025] Since the carrier plate 11 is rectangular, four support adjustment mechanisms are arranged at the four corners of the carrier plate 11 , and support adjustment mechanisms may also be added at the edges according to actual needs.

[0026] The support rod 31 is mounted on the support plate 32 through the cooperation of a ball head and a ball seat, so that the carrier plate 11 can be lifted upward at multiple positions at the same time to improve stability.

[0027] A reinforcing rib 6 is connected between the first hydraulic cylinder 2 and the carrier plate 11 to strengthen the structural stability of the carrier plate 11 and the support frame 3 and prevent the carrier plate 11 from being partially bent due to the concentrated gravity of the counterweight.

[0028] Working principle:

[0029] The entire device is moved to the first test point by the hydraulic flatbed self-propelled vehicle 1, and the counterweight is placed on the carrier plate 11. After the test is completed, the first hydraulic cylinder 2 controls the support frame 3 to be retracted, and the height of the carrier plate 11 is lowered until the wheels of the hydraulic flatbed self-propelled vehicle 1 are in contact with the ground, and then the hydraulic flatbed self-propelled vehicle 1 is started to move to the next test point with the counterweight loaded; after arriving at the next test point, the first hydraulic cylinder 2 is started to control the support frame 3 to extend, and the carrier plate 11 is supported, so that the entire hydraulic flatbed self-propelled vehicle 1 rises until the wheels of the hydraulic flatbed self-propelled vehicle 1 are suspended in the air. At this time, the entire device is at the second test point, and the staff starts the static load test device 12 that has been pre-installed or installed on the spot to conduct the test. Repeating the above test can perform static load tests between multiple test points without repeatedly loading and unloading the counterweight.

[0030] The above description is only an optional embodiment of the present invention, and does not limit the patent scope of the present invention. All equivalent structural changes made by using the contents of the present invention specification and drawings under the inventive concept of the present invention, or directly / indirectly applied in other related technical fields are included in the patent protection scope of the present invention.
