[0026] See Figure 1-3 This utility model relates to an auxiliary trolley for a portable X-ray stress tester, comprising a carriage 1, a support platform 2, and lifting support legs 3. The carriage 1 has a cavity for accommodating the tester and protecting it during transportation. Lifting support legs 3 are located at the four corners of the bottom of the carriage 1, and universal wheels 4 are provided at the bottom of the lifting support legs 3. The support platform 2 is embedded in the top plate 1.1 of the carriage 1, and the top plate 1.1 has a groove corresponding to the support platform 2. One side of the support platform 1.1 is hinged to the top plate 1.1, and the other side is hinged to an electric push rod 6 via an upper fixed seat 5. The upper fixed seat 5 is fixed to the bottom of the support platform 2, and the other end of the electric push rod 6 is hinged to a lower fixed seat 7. The lower fixed seat 7 is fixed inside the carriage 1 via a longitudinal beam 8.

[0027] The electric push rod 6 is located at the longitudinal center of the corresponding side of the support platform 1.1. The rod body of the electric push rod 6 is hinged to the lower fixed seat 7, and the telescopic rod of the electric push rod 6 is hinged to the upper fixed seat 5.

[0028] The support platform 2 is provided with multiple limiting grooves 2.1, which are distributed at the four corners of the support platform 2. A metal block 9 is provided in the limiting groove 2.1, and the top surface of the metal block 9 is lower than the top surface of the support platform 2. The limiting grooves 2.1 serve as equipment support positions, and their number is adapted to the number of universal support feet of the DS-21P portable X-ray stress measuring instrument.

[0029] The bottom surface of the groove is provided with a longitudinal support piece 10 corresponding to the support plate 2, which limits the support plate 2. The longitudinal support piece 10 is located on the side away from the electric push rod 6, so as to avoid the electric push rod 6.

[0030] When the front side panel 1.2 of the carriage 1 is folded down, the front side panel 1.2 of the carriage 1 is hinged to the bottom plate, which facilitates the insertion and removal of the testing instrument.

[0031] The lifting support leg 3 is foldable. The top of the inner leg of the lifting support leg 3 is hinged to the bottom of the carriage, and the left and right lifting support legs can be folded inward to reduce the height of the auxiliary trolley during transportation, facilitating vehicle transport. When the auxiliary trolley needs to be towed or when testing is required, the lifting support leg opens, and the lifting support leg, carriage, and diagonal brace form a stable triangular support structure to ensure structural stability. The lifting support leg 3 is made of aluminum alloy and can be lifted manually or electrically. The height of the carriage, support platform, and testing instrument on it can be adjusted according to the testing environment. In manual mode, the nested inner and outer legs are fixed by spring locking pins, and adjustment holes are equidistantly distributed in the height direction of the inner and outer legs corresponding to the spring locking pins. In electric mode, the outer leg has a built-in lifting device.

[0032] The carriage 1 and the supporting platform 2 are made of composite wood, which is wear-resistant, inexpensive, has high load-bearing capacity and is lightweight.

[0033] The front of the carriage 1 is equipped with a push-pull handle 11, which facilitates the movement of the trolley and can also be used to wind up excess wiring of the tester, thus optimizing the testing environment.

[0034] Working principle:

[0035] The tester is transported to the test site along with the auxiliary trolley. In the initial state, the electric push rod 6 of the auxiliary trolley is retracted inside the carriage 1, and the support platform 2 is flush with the top plate of the carriage 1. The tester is moved from the carriage of the auxiliary trolley to the support platform 2. The universal support feet of the tester are placed on the designated equipment support position on the support platform to perform residual stress testing. The tester host and computer are placed on the left side of the top plate for the convenience of the testers to record data.

[0036] When the height of the test position needs to be adjusted, the height of the four lifting support legs 3 is adjusted synchronously to meet the height adjustment requirements. When the angle of the test position needs to be adjusted, the telescopic rod of the electric push rod 6 extends, and the support platform 2 tilts, realizing the tilt adjustment of the support platform 2 and the tester on it to meet the test conditions. The support platform 2 can be adjusted horizontally upward by 30°. The support platform 2 has reserved equipment support positions to prevent the tester from slipping due to gravity when tilted. The universal support feet have a magnetic attraction function, which further ensures the relative fixation of the position between the tester and the support platform within the 30° tilt angle.

[0037] In addition to the above embodiments, this utility model also includes other implementation methods. All technical solutions formed by equivalent transformation or equivalent substitution should fall within the protection scope of the claims of this utility model.
