Whether it is the height difference between the inner and outer edges of the slope and corners, or the flatness of the road surface, there is a complete set of national standards for testing. Usually, a series of instruments are needed to test the road surface section by section during acceptance. Due to the complex construction road surface and environment, the detector needs to be supported by an auxiliary support device.

The height of the workbench 3 can be adjusted by the setting of the hydraulic cylinder 2, and the clamping and fixing of the detection equipment and the fixing of the base 1 can be achieved by the setting of the fixing component 5.

[0023] The utility model is further described below in conjunction with embodiments.

[0024] Embodiment 1:

[0025] See also Figure 1 - Figure 3 The fixing assembly 5 includes a clamping mechanism 51 and a snap-fitting mechanism 52 fixedly mounted on the clamping mechanism 51. The clamping mechanism 51 is used to drive the snap-fitting mechanism 52 to move its position. The snap-fitting mechanism 52 is used to fix the base 1 so that it has high stability during operation. The cooperation between the clamping mechanism 51 and the snap-fitting mechanism 52 can improve the stability of the detection equipment during operation.

[0026] Push handles 11 are fixedly installed on both sides of one side of the base 1, and universal wheels 12 are movably installed on both sides of one side of the bottom of the base 1, and rollers 13 are arranged on both sides of the other side of the bottom of the base 1. A rotating rod 14 is fixedly installed on the rollers 13 to facilitate the staff to hold the push handle 11 to drive the device to move, which has high flexibility.

[0027] Vertical plates 141 are movably mounted at both ends of the rotating rod 14 , and the tops of the vertical plates 141 are fixedly mounted on the outer wall of the base 1 . The vertical plates 141 can support the rotating rod 14 .

[0028] Sliding rods 31 are slidably installed near the four corners of the workbench 3, and the lower ends of the sliding rods 31 are fixedly installed on the outer wall of the base 1, and the upper ends of the sliding rods 31 are fixedly installed with circular plates 32. The setting of the sliding rods 31 can guide the movement of the workbench 3.

[0029] Specifically, when using the device, the staff can hold the push handle 11 and then push the base 1 to move under the action of the universal wheel 12 and the roller 13, and can move flexibly according to the needs of the inspection position. When the height of the detection equipment needs to be adjusted, the two hydraulic cylinders 2 can be started by an external power supply. When the hydraulic cylinders 2 are working, their output ends will jointly drive the workbench 3 to move upward under the guide limit of the sliding rod 31, so that the height of the workbench 3 and the detection equipment can be adjusted. After the adjustment is completed, it can be stopped.

[0030] Embodiment 2:

[0031] See also Figure 1 - Figure 4 The clamping mechanism 51 includes a mounting plate 511 fixedly mounted on one side of the top of the fixed plate 4 and a threaded rod 512 rotatably mounted on one side of the mounting plate 511, a knob 513 is fixedly mounted on the rear end of the threaded rod 512, and a movable plate 514 is threadedly connected to the outer side of the knob 513 near the front end, and straight plates 515 are arranged on both sides of one side of the movable plate 514, the bottom of the straight plate 515 is fixedly mounted on the outer wall of the outer side of the fixed plate 4, a limited telescopic rod 516 is fixedly mounted on the upper part of one side of the straight plate 515, and the ends of the limited telescopic rod 516 are fixedly mounted on the outer wall of the outer side of the movable plate 514, hinged rods 517 are movably mounted on both sides of the other side of the movable plate 514, and a clamping plate 518 is movably mounted on the other end of the hinged rod 517, and the clamping plate 518 is slidably mounted on the outer wall of the outer side of the workbench 3, and an anti-slip pad 519 is fixedly mounted on the opposite side of the clamping plate 518.

[0032] The clamping mechanism 52 includes a U-shaped rod 521 fixedly installed on the outer side of a clamping plate 518 on one side and a connecting plate 522 fixedly installed at the other end of the U-shaped rod 521. A U-shaped plate 523 is provided on one side of the connecting plate 522, and the connecting plate 522 and the U-shaped plate 523 are elastically connected by a telescopic spring 524. A locking gear 525 is fixedly installed on one side of the inner cavity of the U-shaped plate 523, and a rotating gear 526 is provided on one side of the locking gear 525, and the rotating gear 526 is fixedly installed at the middle part of the outer side of the rotating rod 14.

[0033] Specifically, before moving the device, the detection device needs to be placed on the workbench 3. After the placement is completed, the knob 513 can be turned. When the knob 513 is turned, the threaded rod 512 is driven to rotate. When the threaded rod 512 is rotated, the movable plate 514 is driven to move backward under the guidance of the limit telescopic rod 516. When the movable plate 514 moves backward, it drives the two clamping plates 518 to move relative to each other through the hinge rod 517. The relative movement of the clamping plates 518 can achieve the clamping and fixing of the detection device, and the setting of the anti-slip pad 519 can improve the clamping and fixing effect. When the clamping plate 518 moves, The U-shaped rod 521 is driven to move. When the U-shaped rod 521 moves, the locking gear 525 is driven to move toward the side close to the rotating gear 526 through the connecting plate 522, the U-shaped plate 523 and the telescopic spring 524. When the clamping plate 518 clamps and fixes the detection device, it can stop moving. At this time, the locking gear 525 will also mesh with the rotating gear 526, thereby limiting the roller 13 and preventing it from rotating. The setting of the telescopic spring 524 can prevent the locking gear 525 from meshing with the rotating gear 526 while the clamping plate 518 is still moving, thereby playing a buffering role.

[0034] To sum up: when using the device, the staff can hold the push handle 11 and then push the base 1 to move under the action of the universal wheel 12 and the roller 13, and can move flexibly according to the needs of the inspection position. When the height of the detection equipment needs to be adjusted, the two hydraulic cylinders 2 can be started by an external power supply. When the hydraulic cylinders 2 are working, their output ends will jointly drive the workbench 3 to move upward under the guide limit of the sliding rod 31, so that the height of the workbench 3 and the detection equipment can be adjusted. After the adjustment is completed, it can be stopped. Before moving the device, the detection equipment needs to be placed on the workbench 3. After the placement is completed, the knob 513 can be turned. When the knob 513 is turned, it will drive the threaded rod 512 to rotate. When the threaded rod 512 rotates, it will drive the movable plate 514 to move backward under the guidance of the limit telescopic rod 516, and the movable plate 514 moves backward When the clamping plate 518 moves, the two clamping plates 518 will be driven to move relative to each other through the hinge rod 517. The relative movement of the clamping plates 518 can realize the clamping and fixing of the detection equipment, and the setting of the anti-slip pad 519 can improve the clamping and fixing effect. When the clamping plate 518 moves, it will also drive the U-shaped rod 521 to move. When the U-shaped rod 521 moves, it will drive the positioning gear 525 to move to the side close to the rotating gear 526 through the connecting plate 522, the U-shaped plate 523 and the telescopic spring 524. When the clamping plate 518 realizes the clamping and fixing of the detection equipment, it will stop moving. At this time, the positioning gear 525 will also mesh with the rotating gear 526, thereby limiting the roller 13 and preventing it from rotating. The setting of the telescopic spring 524 can prevent the positioning gear 525 from meshing with the rotating gear 526 while the clamping plate 518 is still moving, thereby playing a buffering role.
