For those skilled in the art, the specific meaning of the above terms in the present application can be understood according to the specific circumstances.

[0021] Embodiment 1

[0022] The embodiment provides a full-hanging multifunctional test vehicle in the field, specifically as follows Figure 1As shown, including full trailer chassis 3, the full trailer chassis 3 is installed with support hydraulic cylinder 1, lifting tower base 4, test cabinet 5, hydraulic pump station 9, lifting tower support frame 11, the lifting tower base 4 is installed with lifting tower 2, the lifting tower 2 is installed with test rotary table 10, the support hydraulic cylinder 1 is connected with the lifting tower 2; the support hydraulic cylinder 1 is used to support the lifting tower 2, so that the lifting tower 2 is switched between the laid down state and the standing state, the test cabinet 5 is used to test the connection and debugging of all equipment, the hydraulic pump station 9 is used to control the action of the full trailer chassis 3, the lifting tower support frame 11 is used to support the single lifting tower 2 in the laid down state. The lifting tower base 4 is slidingly connected to the full trailer chassis 3, when the lifting tower 2 is laid down, the lifting tower base 4 is at one end close to the test cabinet 5 on the moving route; when the lifting tower 2 is standing, the lifting tower base 4 is at one end away from the test cabinet 5 on the moving route; the full trailer chassis 3 is provided with a locking mechanism, which is used to fix the position of the lifting tower base 4. The finished equipment such as the support hydraulic cylinder 1, the test cabinet 5, the hydraulic pump station 9 is a commercially available existing product, the specific model is the adaptability of the person skilled in the art, which is not described here. The lifting tower 2 is a commercially available product, which has an independent power source and can realize arbitrary adjustment of height, and the specific structure is not described here.

[0023] When the lifting tower 2 needs to be erected, first move the lifting tower base 4 so that the lifting tower base 4 is at one end away from the test cabinet 5 on the moving route, and use the locking mechanism to limit the position of the lifting tower base 4, at this time the lifting tower base 4 is at the center position of the full trailer chassis 3, then use the support hydraulic cylinder 1 to push the lifting tower 2 so that the lifting tower 2 is erected, at this time the gravity of the lifting tower 2 is applied to the middle part of the full trailer chassis 3, that is, the gravity applied by the lifting tower 2 to the full trailer chassis 3 can be evenly distributed on the plurality of wheels of the full trailer chassis 3, preventing the full trailer chassis 3 from falling; when the full trailer chassis 3 needs to be moved, connect the hook of the tractor to the full trailer chassis 3, and then use the support hydraulic cylinder 1 to lay down the lifting tower 2, at this time the lifting tower 2 is not completely on the full trailer chassis 3 (the projection of the lifting tower 2 is not completely on the full trailer chassis 3 from the top view), due to the shielding of the lifting tower 2, which makes the connection of the tractor and the full trailer chassis 3 become inconvenient, and increases the overall length of the test vehicle, so the lifting tower base 4 needs to be moved so that the lifting tower base 4 is at one end close to the test cabinet 5 on the moving route, at this time the lifting tower 2 is completely on the full trailer chassis 3 (the projection of the lifting tower 2 is completely on the full trailer chassis 3 from the top view), at this time the connection of the tractor and the full trailer chassis 3 is not shielded and is more convenient, and the overall length of the test vehicle is the length of the full trailer chassis 3.

[0024] By setting a movable lifting tower base 4, the lifting tower 2 can move relative to the full trailer chassis 3, taking into account the overall length of the test vehicle and the convenience of towing, while ensuring the force balance of the full trailer chassis 3 when the lifting tower 2 is erected.

[0025] Example 2:

[0026] This embodiment further extends the above embodiment, specifically as follows: Figure 2 , Figure 3 As shown, the full-mounted chassis 3 includes a chassis frame 31, a support platform 34 is mounted on the chassis frame 31, a slide rail 32 is provided on the support platform 34, and a slider 37 is slidably connected to the slide rail 32; the lifting tower base 4 includes a support base 41, the lifting tower 2 is rotatably connected to the support base 41, a connecting plate 42 is mounted on the support base 41, and the connecting plate 42 is fixedly connected to the slider 37.

[0027] By setting up the cooperation of slide rail 32 and slider 37, the moving resistance of the lifting tower base 4 is reduced, saving energy and reducing labor intensity.

[0028] The other parts of this embodiment are the same as those in the above embodiments, and will not be described again.

[0029] Example 3:

[0030] This embodiment further extends the above embodiment, specifically as follows: Figure 4 As shown, a sliding groove 33 is provided on the chassis frame 31. The locking mechanism includes a limiting sliding rod 43 installed on the support base 41 and a locking wedge 35 slidably connected to the sliding groove 33. The limiting sliding rod 43 slides in the sliding groove 33, and the locking wedge 35 is located in the sliding groove 33. A spring 36 is provided between the locking wedge 35 and the sliding groove 33. The locking wedge 35 is used to limit the position of the limiting sliding rod 43.

[0031] When the limiting slide bar 43 is about to move to the end of the slide groove 33, the limiting slide bar 43 contacts the inclined surface of the locking wedge block 35 and squeezes the locking wedge block 35. At this time, the spring 36 is compressed, the locking wedge block 35 retracts into the chassis frame 31, and the limiting slide bar 43 passes over the locking wedge block 35 to reach the end of the slide groove 33. At this time, the locking wedge block 35 rebounds under the action of the spring 36. The locking wedge block 35 cooperates with the end of the slide groove 33 to limit the limiting slide bar 43, thereby achieving the limitation of the lifting tower base 4. When it is necessary to move the lifting tower base 4 again, manually overcome the elastic force of the spring 36 and pull down the locking wedge block 35 so that the locking wedge block 35 does not temporarily limit the limiting slide bar 43, and the lifting tower base 4 can be moved.

[0032] Through the arrangement, when the lifting tower base 4 moves, the locking mechanism can automatically limit the lifting tower base 4 without other operations; when it is needed to move the lifting tower base 4 again, the lifting tower base 4 can be released from the limitation after manual confirmation, which has high safety.

[0033] Since the locking wedge 35 on both sides can limit the limiting slide rod 43, the two locking wedges 35 need to be pulled at the same time to move the lifting tower base 4, which can prevent the lifting tower base 4 from losing the limitation due to the mistaken pulling of one locking wedge 35 by a person, and further improve the safety of the locking mechanism.

[0034] The other parts of the embodiment are the same as those of the above-described embodiments, and will not be described herein again.
