Detailed Description
The following description of the present invention will be made in detail with reference to the accompanying drawings 1 to 8.
The technical scheme of its solution is, embodiment 1, an asphalt concrete quality testing device, including measuring section of thick bamboo 1 and the toper penetrating end 2 of measuring section of thick bamboo 1 lower extreme coaxial coupling, its characterized in that, vertical sliding connection has measuring ring 3 on the measuring section of thick bamboo 1, be fixed with bilateral symmetry's L shape bracing piece 4 on the measuring ring 3, still include the support ring 5 that can the interval cover on measuring section of thick bamboo 1, support ring 5 is supported by two L shape bracing pieces 4 on upper portion, it has vertical extension's first spout 6 to open on the measuring section of thick bamboo 1 leading flank, it has the measuring block 7 of the sliding fit in first spout 6 that upwards stretches out measuring ring 3 to measure the ring 3 internal fixation, be equipped with scale 8 on the measuring section of thick bamboo 1 of first spout 6 one side.
When the embodiment is used, the bottom end of the first sliding groove 6 can be arranged, so that when the measuring block 7 contacts the bottom end of the first sliding groove 6, the lower end surface of the support ring 5 is flush with the bottom end of the piercing end 2. The measuring cylinder 1 is placed at the upper end of a concrete layer, then the measuring cylinder is penetrated into the concrete through the penetrating end 2, and the penetrating end 2 drives the measuring cylinder 1 to descend until the bottom is touched. During the lowering of the measuring cylinder 1. Because the bottom surface of the support ring 5 is large, the support ring 5 is held on the concrete surface and does not fall, and then the measuring ring 3 connected with the support ring 5 does not fall, so that the measuring block 7 slides along the first sliding groove 6, when the penetrating end 2 is in a bottom contact state, the scale 8 indicated by the measuring block 7 is the thickness of the concrete (if the scale 8 indicated by the starting scale 8 is not 0, the starting scale 8 can be marked, and then the final scale 8 is subtracted from the starting scale 8, so that the thickness of the concrete is obtained). The utility model discloses a measure the convenience, measurement personnel only need insert it in the concrete, just can directly read out the thickness of concrete, can not cause personnel to scald. The scale can be scale marks or scale grooves.
This embodiment is based on embodiment 1, and adds a structure for positioning the measurement ring 3 in real time. Before the measuring cylinder 1 is inserted into the concrete downwards, the sliding rod 10 is shifted leftwards by hands to drive the first friction blocks 15 to move leftwards, so that the first friction blocks 15 and the second friction blocks 17 are spaced and cannot be contacted. And then the measuring ring is downwards inserted into concrete, after the measuring ring enters the concrete and touches the bottom, the sliding rod 10 is released, the sliding rod 10 is reset under the action of the first spring 11 and presses the first friction block 16 to move rightwards, so that the first friction block 16 and the second friction block 17 at the position of the second friction block 17 are in pressing contact, and the opposite surfaces of the first friction block 16 and the second friction block 17 are friction surfaces, so that the measuring ring 3 is positioned at the current position under the action of friction force, then the measuring cylinder 1 is pulled out, and the scale 8 is read. This measurement ring 3 can fix a position in real time, makes things convenient for surveying staff to take out the accurate scale 8 that reads in back, has avoided surveying staff to be scalded the risk.
When the embodiment is used, the first friction block 15 and the second friction block 17 can slide in the positioning hole 9, and when the embodiment is arranged, the first friction block 15 can be arranged to be partially positioned in the positioning hole 9 all the time and cannot be completely separated. The second friction block 7 may be provided so that a part thereof does not always disengage from the positioning hole 9.
When the embodiment is used, the two adjacent first friction blocks 15 are in seamless butt joint and can slide relatively, so that after the measuring cylinder is inserted into concrete, the concrete cannot enter the measuring cylinder 1 along the interval between the two first sliding blocks, and the cleanness and tidiness of the measuring cylinder 1 are guaranteed.
In embodiment 5, on the basis of embodiment 2, a vertical second sliding groove 18 is formed in the right side surface of the upper portion of the sliding rod 10, one end of a shift lever 19 is vertically slid in the second sliding groove 18, a rotating shaft 20 is rotatably connected to the middle of the shift lever 19, two ends of the rotating shaft 20 are supported by a connecting rod 21 fixed in the measuring cylinder 1, and the other end of the shift lever 19 extends obliquely upward toward the right side. A torsion spring 22 sleeved on the rotating shaft 20 is connected between the shift lever 19 and the connecting rod 21, and the torsion spring 22 enables the lower end of the shift lever 19 to always tend to move towards the sliding rod 10. When the upper end of the deflector rod 19 is pulled downwards, the deflector rod 19 rotates by taking the rotating shaft 20 as a fulcrum, and the lower end of the deflector rod 19 is in sliding fit with the second sliding groove 18, so that the lower end of the deflector rod 19 can pull the slide rod 10 to move towards the direction far away from the positioning hole 9, the slide rod 10 touches the baffle 14 in the moving process, so as to drive the push rod 13 to move towards the direction far away from the positioning hole 9, the push rod 13 drives the first friction block 15 to move towards the direction far away from the positioning hole 9, at the moment, the first friction block 15 cannot be in contact with the second friction block 17, therefore, the measuring ring 3 can freely vertically slide on the measuring cylinder 1 at the moment, namely, when the measuring cylinder 1 is inserted into the concrete, because the support ring 5 is supported on the surface of the concrete, the measuring ring 3 is static and different at the moment, the measuring ring 3 and the measuring cylinder 1 relatively move, when the measuring cylinder 1, at this time, the shift lever 19 is released, the slide rod 10 is reset under the action of the first spring 11, so that the first friction block 15 and the second friction block 17 at the position of the measuring ring 3 are matched, the measuring ring 3 is positioned at the current position of the measuring cylinder 1, then the measuring cylinder 1 is pulled out of the concrete, and the thickness of the concrete can be obtained by reading the numerical value of the scale 8.
In example 10, in addition to example 5, both ends of the shift lever 19 are arc surfaces. Two ends of the shift lever 19 are arranged into arc surfaces, and two ends of the shift lever 19 slide and rotate on the contact surfaces of the second sliding chute 18 and the pressing plate 26 respectively.
The utility model provides a so be provided with second spring 16, because when measuring section of thick bamboo 1 inserts in the concrete, be full of the concrete around measuring section of thick bamboo 1, slide bar 10 moves towards locating hole 9 direction under the elasticity of first spring 11 this moment, if the locating hole 9 inside and outside part in the concrete is being filled with the concrete, then the concrete blocks first clutch blocks 15 and moves towards the right side, if do not have second spring 16, then influence the contact of first clutch blocks 15 on upper portion and second clutch blocks 17 after first clutch blocks 15 of lower part are blockked, consequently with a plurality of first clutch blocks 15 departments in addition second spring 16, make it have certain flexibility, also be the first clutch blocks 15 of lower part do not influence the removal of the first clutch blocks 15 on upper portion, the cooperation of first clutch blocks 15 on concrete upper portion and second clutch blocks 17 has been guaranteed.
