[0026] In order to make the purpose, technical solution and advantages of the utility model more clear, the following is a further detailed description of a concrete pavement core-pulling machine fixing device of the utility model in combination with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.
[0027] Please refer to Figure 1-Figure 4 A fixing device for a concrete pavement core-pulling machine 600, characterized in that it comprises:
[0028] A base 100, a plurality of supporting legs 120 are provided at the bottom of the base 100, and a wheel bearing area 130 is provided at one end of the base 100;
[0029] The mounting seat 200 is fixed to one end of the base 100 away from the wheel pressure bearing area 130;
[0030] The guide rail 300 is fixedly connected to the mounting seat 200;
[0031] The sliding sleeve 400 is slidably connected to the guide rail 300 and connected to the core pulling machine 600;
[0032] The locking mechanism 500 includes a force rod 510 and a locking screw 520 . The locking screw 520 is threadedly connected to the sliding sleeve 400 and passes through the sliding sleeve 400 to abut against the guide rail 300 . The force rod 510 and the locking screw 520 are vertically connected.
[0033] The guide rail 300 is fixed to one end of the base 100 through the mounting seat 200, and the wheel pressure area 130 is set at the other end. By driving the vehicle so that the wheel 700 is pressed on the wheel pressure area 130, it can be conveniently fixed. It is convenient, fast and safe, and can be used on both concrete and asphalt roads. Support feet 120 are set at the bottom of the base 100 to reduce the contact area with the road surface, increase the pressure, improve the grip, and reduce the instability of the steel trough caused by the unevenness of the road surface. Practice has proved that this device can be used to drill asphalt roads, while the core pulling machine 600 could not be fixed on asphalt roads before; concrete roads can be drilled safely and quickly, and the time for removing the road expansion screws after the test is completed is saved.
[0034] Please refer to Figure 3 The bottom of the base 100 is provided with a groove 110, and the groove 110 runs through the direction from the wheel pressure area 130 to the mounting seat 200. The groove 110 is provided to reduce the overall weight and facilitate transportation.
[0035] Please refer to Figure 1 and Figure 4 The mounting seat 200 is screwed and fixed to the base 100, so as to form a detachable connection, which is convenient for installation and disassembly.
[0036] Preferably, the mounting seat 200 and the guide rail 300 are integrally formed or welded together.
[0037] Particularly, the mounting seat 200 is provided with a mounting groove or a mounting hole, and the guide rail 300 is disposed in the mounting groove or the mounting hole and is welded to the mounting seat 200. When welding is adopted, the mounting groove and the mounting hole are provided to be fixed and stable.
[0038] Preferably, the support foot 120 is welded to the base 100. Alternatively, the support foot 120 may be integrally formed as required.
[0039] Please refer to Figure 4 The wheel pressure bearing area 130 has an arc groove 131 which is arranged perpendicular to the direction from the wheel pressure bearing area 130 to the mounting seat 200 .
[0040] Please refer to Figure 1-Figure 4 The force rod 510 is slidably connected to the locking screw 520, and anti-slip convex balls 511 are welded at both ends of the force rod 510. The force rod 510 is mainly used to facilitate the rotation of the locking screw 520. The anti-slip convex balls 511 can prevent the force rod 510 from being separated from the locking screw 520. The ball shape can improve safety and avoid scratching the human body.
[0041] It should be noted that if the embodiments of the present invention involve directional indications (such as up, down, left, right, front, back...), the directional indications are only used to explain the relative position relationship, movement status, etc. between the components under a certain specific posture (as shown in the accompanying drawings). If the specific posture changes, the directional indication will also change accordingly.
[0042] In summary, the utility model provides a concrete pavement core-pulling machine fixing device, which fixes the guide rail at one end of the base through a mounting seat, and sets a wheel pressure zone at the other end, so that the wheel can conveniently play a fixing role, which is convenient, fast and safe, and can be used on both concrete and asphalt pavements. Support feet are set at the bottom of the base to reduce the contact area with the road surface, increase the pressure, improve the grip, and reduce the instability of the steel trough caused by the unevenness of the road surface. Practice has proved that this device can be used to drill asphalt pavements, while the core-pulling machine could not be fixed on asphalt pavements before; concrete pavements can be drilled safely and quickly, and the time for removing the pavement expansion screws after the test is completed is saved.
