Detailed Description
The following description of the embodiments of the present utility model will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present utility model, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the utility model without making any inventive effort, are intended to be within the scope of the utility model.
Referring to fig. 1-4, an asphalt concrete structural layer paving thickness detection device comprises a shell 1, wherein a scale mark 2 is arranged on one side of the shell 1, a through hole is formed in the middle of the shell 1, a vertical connecting rod 4 integrally penetrates through the shell 1 through the through hole, a pull ring 5 is fixed at the top of the vertical connecting rod 4, a detection block 6 is fixed at the bottom of the vertical connecting rod 4, and the detection block 6 is integrally triangular prism-shaped.
Meanwhile, a through movable groove 8 is formed in one side of the shell 1, an indicator 7 is fixedly connected to the side edge of the vertical connecting rod 4, the indicator 7 is U-shaped, the U-shaped indicator 7 penetrates through the movable groove 8, and the tail end of the indicator 7 is triangular and points to the scale marks 2.
The side symmetry welded fastening of casing 1 has curb plate 9, is provided with the bubble 10 in the middle of the upper surface of curb plate 9, can judge through the state of observing bubble 10 that curb plate 9 and casing 1 are in the horizontality, and the below fixedly connected with toper thorn 11 at curb plate 9, and when using, toper thorn 11 can help the whole fixedly of the device, and the device removes when avoiding measuring.
The side of the shell 1 opposite to the movable groove 8 is fixedly connected with a handle 3, which is convenient for taking the device.
The vertical connecting rod 4 is fixedly connected with a stop block 12, and a cavity is formed in the corresponding position inside the shell 1, wherein the movable baffle 14 is arranged in the cavity, a spring 13 is arranged between the movable baffle 14 and the cavity wall, a control rod 15 is connected above the movable baffle 14, the upper end of the control rod 15 extends out of the shell 1, and the control rod 15 can drive the movable baffle 14 to move.
Wherein the upper surface of the stopper 12 and the lower surface of the movable shutter 14 are provided as inclined surfaces.
Working process and principle: the initial state is shown in fig. 3, in which the vertical link 4 and the detection block 6 are received into the housing 1, and as shown in fig. 4, the stopper 12 is above the movable baffle 14, that is, the movable baffle 14 blocks the stopper 12 and the vertical link 4 from falling.
When the device is used, firstly, the device is placed on an asphalt pavement to be detected, at the moment, the level bubble 10 on the side plate 9 is required to be observed, the device is guaranteed to be in a horizontal position, when the device is prevented from being inclined, the vertical connecting rod 4 and the detection block 6 are inclined, so that measurement data are inaccurate, the conical thorn 11 below the side plate 9 can help the device to be well fixed on the surface of a roadbed, and the device is prevented from laterally moving and sliding when the detection block 6 is pressed down.
When the vertical link 4 needs to be pressed down, as shown in fig. 4, the movable baffle 14 is driven to move leftwards by the control rod 15, the spring 13 is compressed, the movable baffle 14 and the stop block 12 are separated from contact, the vertical link 4, the indicator 7 and the detecting block 6 fall under the action of gravity, namely the lower surface of the detecting block 6 contacts the asphalt surface, and the height of the scale mark 2 pointed by the indicator 7 is defined as the height A.
The vertical connecting rod 4 and the detecting block 6 are driven to be pressed downwards through the pull ring 5, the needle head of the existing pointer type probe is small and is easier to insert into asphalt, but the contact area of the needle head is small, when asphalt is paved, the lower layer is generally constructed by using materials such as broken stone, gravel, lime soil or various industrial waste residues, and the like, and the pointer type probe is possibly inserted into a cushion layer below the asphalt layer, so that the measuring structure is inaccurate.
The device detection block 6 has a regular triangular prism structure, namely, the contact surface of the device detection block and asphalt is a line, so that the problem can be avoided to a great extent.
When the vertical connecting rod 4 drives the detection block 6 to move downwards, the indicator 7 also moves along the scale mark 2, and stops when the lower surface of the detection block 6 contacts the lower cushion layer, at the moment, the numerical value corresponding to the indicator 7 and the scale mark 2 is measured as the height B, and the difference between the height A and the height B is the paving thickness of the asphalt layer.
In order to ensure accurate measurement results, it is generally necessary to compare the results of such measurements.
When the device is retracted, the vertical connecting rod 4 is pulled upwards through the pull ring 5, because the upper surface of the stop block 12 and the lower surface of the movable baffle 14 are provided with inclined surfaces, when the stop block 12 contacts the lower surface of the movable baffle 14 from bottom to top, the movable baffle 14 is pushed to move, the spring 13 is compressed, and when the stop block 12 moves to the position above the movable baffle 14, the movable baffle 14 is restored to the initial position under the action of the spring 13, and then the device is conveniently and directly taken through the handle 3.
Although embodiments of the present utility model have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made therein without departing from the principles and spirit of the utility model, the scope of which is defined in the appended claims and their equivalents.
