Description

Technical Field

[0001] The present application relates to the technical field of detection devices, and more specifically, to a road cavity detector. Background Art

[0002] Roads are infrastructure for various trackless vehicles and pedestrians to pass through. According to their usage characteristics, they are divided into highways, urban roads, rural roads, factory and mine roads, forestry roads, test roads, competition roads, automobile test roads, workshop passages, and school roads. After long-term use, roads are prone to cracks and sinking. The main reason for this phenomenon is the appearance of voids between the road structure layers. Therefore, after the road construction is completed, it is necessary to use road void detection devices for detection. At present, the existing detection devices do not have ultrasonic detection functions, and cannot accurately detect the void information and other data such as density of the road, resulting in insufficient details of road detection data. At the same time, the existing detection devices do not have a convenient function to adjust the handle height, which is easy to cause height mismatch when used by workers of different heights, resulting in difficulty in operation for the workers and reduced work efficiency.

[0003] The document with prior art publication number CN214225024U provides a road cavity detection device. Through the design of a connecting shaft and a hinge block, the detection device can have a convenient function of adjusting the handle height, so that workers of different heights can easily adjust to a suitable height when using it, thereby improving the operating comfort of the workers and improving work efficiency.

[0004] Although the above-mentioned prior art solution can achieve the relevant beneficial effects through the structure of the prior art, it still has the following defects: when the device is in use, the overall structure occupies a large space, which is inconvenient to carry and use. At the same time, the ultrasonic detector cannot be protected after use, and it is easy to cause damage due to collision with other equipment during transportation.

[0005] In view of this, we propose a road hole detector. Utility Model Content

[0027] The present application is further described in detail below in conjunction with the accompanying drawings.

[0028] A road hole detector includes an ultrasonic detector 1, which includes an inner shell 101 and an outer shell 2 sleeved on the outer shell 101. The inner shell 101 is suspended and fixed in the outer shell 2. A detection port 201 is opened at the bottom of the outer shell 2. A baffle 203 is detachably installed on the detection port 201. A retractable traction rod 3 is rotatably connected to the outer shell 2. A bracket 204 is slidably arranged in the outer shell 2. A plurality of wheels 205 are rotatably connected to the bracket 204. The bracket 204 can be stored in the outer shell 2.

[0029] Reference Figure 1-Figure 4 The traction rod 3 is rotatably connected to the shaft of the outer shell 2 so that the traction rod 3 can adapt to users of different heights. It is suspended between the inner shell 101 and the outer shell 2. When the outer shell 2 is impacted by external force, the ultrasonic detector 1 fixed in the inner shell 101 can be prevented from being damaged by impact. At the same time, when in use, the bracket 204 is lowered and the wheels 205 protrude from the outer shell 2. At this time, the retractable traction rod 3 can be dragged along the road to perform cavity detection. After use, the bracket 204 and the wheels 205 are stored in the outer shell 2, the traction rod 3 is retracted, and the detection port 201 is blocked by the baffle 203, so that the ultrasonic detector 1 can be protected when not in use, while reducing the space occupied and facilitating transportation.

[0030] A guide rail 202 is symmetrically fixed to one side of the housing 2 close to the detection port 201 , a baffle 203 is slidably disposed between the two guide rails 202 , and a first locking screw 2031 that abuts against the housing 2 is threadedly connected to one side of the baffle 203 .

[0031] Reference Figure 2 and Figure 3 The guide rail 202 is an L-plate, and the baffle 203 is slidably arranged on the two guide rails 202 and abuts against the bottom wall of the shell 2 through the first locking screw 2031 to achieve the fixation of the baffle 203 and the shell 2.

[0032] The bracket 204 includes four legs 2041 and a crossbeam 2042 for fixing the four legs 2041 . The legs 2041 pass through the housing 2 . A second locking screw 206 that abuts against the legs 2041 is threadedly connected to one side of the housing 2 .

[0033] Reference Figure 2 and Figure 4 After the four legs 2041 are fixed by the crossbeam 2042, the four legs 2041 can be raised and lowered synchronously. The wheel 205 is axially connected to the lower end of the leg 2041, so that the wheel 205 can be extended or retracted by adjusting the leg 2041 on the shell 2, and the second locking screw 206 is against the leg 2041 to fix the bracket 204 and the shell 2.

[0034] A plurality of columnar shock-absorbing pads 102 are fixedly mounted between the upper and lower surfaces of the inner shell 101 and the outer wall of the outer shell 2 .

[0035] Reference Figure 3 The upper and lower surfaces of the inner shell 101 are fixed by a plurality of columnar shock-absorbing pads 102, so that the inner shell 101 and the outer shell 2 are suspended in the air to form a buffer area. At the same time, under the action of the shock-absorbing pads 102, the vibration of the inner shell 101 and the ultrasonic detector 1 caused during the movement can be reduced.

[0036] The traction rod 3 is a telescopic rod.

[0037] Reference Figure 1 The traction rod 3 is a telescopic rod made of aluminum alloy to increase the service life of the traction rod 3.

[0038] Working principle: The user adjusts the length of the traction rod 3 to suit his or her height, and then loosens the first locking screw 2031 to allow the baffle 203 to slide along the guide rail 202 and open the detection port 201. The first locking screw 2031 is then fixed to the outer shell 2, and the bracket 204 is stretched downward to allow the wheel 205 to protrude from the lower surface of the outer shell 2. The support leg 2041 is then fixed to the outer shell 2 through multiple second locking screws 206, and finally the traction rod 3 is dragged.
