[0027] The embodiments of the present utility model will be further described below with reference to the drawings.

[0028] Embodiment:

[0029] As Figures 1 - 3 shown, a density detection device for the construction of on-site filling materials of a high-speed rail track plate 60 includes a top bracket 10, a slide rail 20, a detection device, a lifting component 40 and a moving component. The slide rail 20 is vertically arranged, and its top is connected to both sides of the top bracket 10. The detection device includes an equipment shell 30 and a working unit 31. The working unit 31 mainly includes an ultrasonic generating unit and an ultrasonic receiving unit of the prior art, which are respectively arranged at the bottoms of the two equipment shells 30 for ultrasonic density detection. A slide block 32 slidably connected to the slide rail 20 is arranged on the outer side of the equipment shell 30. The lifting component 40 is arranged between the slide rail 20 and the equipment shell 30 for driving the equipment shell 30 to move up and down relative to the slide rail 20. The moving component includes a connecting rod 51 and a connecting plate 52. There are two connecting rods 51, which are respectively vertically arranged on both sides of the bottom of the top bracket 10 and are between the two slide rails 20. The connecting plate 52 is arranged at the bottom of the connecting rod 51, and two universal wheels 53 are arranged at the bottom of the connecting plate 52 to ensure stable movement.

[0030] The working principle of the above technical solution is as follows:

[0031] During detection, the moving component supports the top bracket 10 and the detection device. The working unit 31 of the detection device is aligned with the gap between two adjacent track slabs 60. The equipment housing 30 is lowered through the lifting component 40 for density detection. The detection principle is prior art and will not be elaborated here. After detection, it can be lifted by the lifting component 40 until the working unit 31 is higher than the universal wheels 53. Since the universal wheels 53 always contact the ground, the entire detection device can be pushed to the next location for detection, which is convenient to operate and saves time and effort.

[0032] In another embodiment, as Figure 1 and Figure 4 shown, a telescopic rod 11 for telescopically changing the horizontal length of the top bracket 10 is provided in the middle of the top bracket 10; plug-in shells 12 and plug-in plates 13 matching the plug-in shells 12 are respectively provided at the top of the top bracket 10 corresponding to both ends of the telescopic rod 11. A handle 14 is provided on the plug-in plate 13, and a card slot 15 matching the handle 14 is provided at the top of the plug-in shell 12.

[0033] The top bracket 10 can be horizontally adjusted in length, with flexible usage conditions. After use, the telescopic rod 11 can be retracted to save space and facilitate transportation; when the telescopic rod 11 is retracted, the plug-in plate 13 can be inserted into the plug-in shell 12. When the middle part of the top bracket 10 is subjected to a vertical pressure, the plug-in plate 13 can bear part of the pressure; the handle 14 is snapped into the card slot 15, and the handle 14 can be held by hand to lift the detection device, which is convenient for lifting during transportation.

[0034] In another embodiment, as Figure 3 shown, the lifting component 40 includes a push rod 41, a rotating shaft 42, a support piece 43, a first connecting piece 44, a second connecting piece 45, and a connecting shaft 46. The support piece 43 includes two pieces, symmetrically arranged on one side of the slide rail 20 parallel to the telescopic rod 11. A rotating hole for rotatably connecting the rotating shaft 42 is provided on the support piece 43. The rotating shafts 42 are symmetrically arranged on both sides of the end of the push rod 41. The end of the rotating shaft 42 away from the top bracket 10 extends outside the rotating hole and is connected to one end of the first connecting piece 44. The other end of the first connecting piece 44 is hinged to one end of the second connecting piece 45. The connecting shaft 46 is arranged on the side of the equipment housing 30 away from the top bracket 10, and the other end of the second connecting piece 45 is rotatably connected to the connecting shaft 46; among them, an intermediate rod 47 is connected between the two push rods 41.

[0035] The two push rods 41 can be simultaneously manipulated through the intermediate rod 47. The push rods 41 are convenient for pushing the detection device. When the push rods 41 are rotated up and down, the rotating shafts 42 rotate, causing the end of the first connecting piece 44 connecting the second connecting piece 45 to rotate up and down, and the second connecting piece 45 can be lifted and lowered, realizing the lifting of the equipment housing 30.

[0036] In another embodiment, as Figures 1 - 2As shown, feet 33 are provided on the front and rear sides of the bottom of the device housing 30. That is, when the working unit 31 is aligned with the gap between two adjacent track slabs 60, the feet 33 are respectively in contact with the tops of the two track slabs 60 to play a supporting role.

[0037] In another embodiment, as Figure 1 shown, a support rod 16 is provided between the slide rail 20 and the connecting rod 51, and a reinforcing rib 17 is provided between the bottom of the top bracket 10 and the slide rail 20. This is used to increase the structural stability of the detection device.

[0038] The above-described embodiments only represent the specific implementation manners of the present utility model, and the description thereof is relatively specific and detailed. However, it should not be construed as a limitation on the scope of the patent of the present utility model. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present utility model, several modifications and improvements can still be made, and these all belong to the protection scope of the present utility model.
