Description

TECHNICAL FIELD

[0001] The utility model relates to engineering technical field, more particularly, a kind of rammer compactor rammer settlement observation device. BACKGROUND

[0002] Rammer compactor is a kind of engineering machinery equipment for foundation treatment, compacts soil by heavy hammer impact or high-frequency vibration, to improve the density, bearing capacity and stability of foundation. Its core principle is to convert gravitational potential energy into impact force (such as free-falling weight) or mechanical vibration energy, so that soil particles are rearranged, air and water are discharged, and more stable foundation structure is formed.

[0003] In the construction process of rammer compactor, the measurement of rammer settlement is an important parameter related to the quality of the project. With the development of sensor technology, the measurement of rammer settlement in the prior art can be digitized and controlled. However, sensors are expensive and prone to wear and tear, so in more small-scale projects, people rely more on traditional manual measurement methods to detect rammer settlement. Traditional manual measurement is to set a ruler on the top of the rammer, and then use a level to record the ruler reading. Due to the large impact of the rammer falling, the strength requirement of the slender ruler is high, and the ruler is easy to tilt during impact, so manual re-setting is required. In patent CN222139974U, the ruler is set on the lifting hook of the rammer, thereby avoiding the trouble of manually re-setting the ruler repeatedly, but the ruler in this patent is in a suspended state, and there is a large error in the gap between the bottom end of the ruler and the top of the rammer, resulting in a large measurement error.

Embodiment

[0025] The embodiment provides a rammer compaction amount observation device 100 of a strong rammer, which refers to Figure 1 As shown in the figure, it comprises a fixing seat 110, a mounting bracket 120 and a scale 130.

[0026] Among them, as Figure 1 And Figure 2As shown, the fixing base 110 is used on the lifting hook of the rammer; the mounting bracket 120 is detachably connected with the fixing base 110, the mounting bracket 120 is provided with a fixing ring 121 at an end away from the fixing base 110, the scale 130 is sleeved in the fixing ring 121 and is in sliding connection with the fixing ring 121; the top of the scale 130 is provided with a limiting ring 131 which is above the fixing ring 121. After the rammer is struck, the lifting hook moves downward to approach the rammer and is reconnected with the rammer, at this time, the lifting hook and the rammer are in a relaxed state, the bottom of the scale 130 is in contact with the top of the rammer, and the sliding connection between the scale 130 and the fixing ring 121 avoids the damage of the hard contact between the scale 130 and the top of the rammer. When the lifting hook is straightened to reach a position where the rammer is about to be lifted, the lifting hook and the rammer are in a taut state, at this time, the fixing ring 121 abuts against the limiting ring 131 to lift the scale 130 away from the surface of the rammer. Through such a setting, when measurement is needed, the scale 130 is in contact with the top of the rammer, and when measurement is not needed, the scale 130 is separated from the rammer, thereby reducing the measurement error.

[0027] Further, the fixing ring 121 is made of two half-ring-shaped arc-shaped pieces 1211 which are spliced together, both ends of the two arc-shaped pieces 1211 are provided with connecting ears 1212 for connecting the two arc-shaped pieces 1211. The connecting ears 1212 are provided with matching holes which penetrate through the connecting ears 1212 along the thickness direction of the connecting ears 1212; the connecting ears 1212 of the two adjacent arc-shaped pieces 1211 can be fixed by a threaded connecting piece penetrating through the matching holes. The spliced design makes the scale 130 be better detached from the fixing ring 121, thereby facilitating the maintenance and replacement of the scale 130.

[0028] As shown in Figure 1 and Figure 2 , the bottom of the scale 130 is provided with a magnet disc 132 which is coaxially arranged with the scale 130. The magnet disc 132 can be adsorbed on the top of the rammer to play a fixing role and prevent the scale 130 from sliding. The diameter of the magnet disc 132 is 3-5 times of the scale 130. Under this size, the magnet disc 132 can be more stably adsorbed while maintaining the vertical state of the scale 130.

[0029] Further, the top of the magnet disc 132 is provided with a plug hole for inserting the scale 130, the inner wall of the plug hole is provided with an internal thread, and the bottom end of the scale 130 is provided with an external thread for cooperating with the internal thread. The detachable connection between the magnet disc 132 and the scale 130 facilitates the separate disassembly and replacement of the two, and also facilitates the separate storage.

[0030] As shown in Figure 1 and Figure 2As shown, the mounting bracket 120 comprises a mounting plate 122 and a connecting rod 123, the mounting plate 122 is horizontally arranged and parallel to the mounting surface of the fixing base 110, the connecting rod 123 extends from the middle of the mounting plate 122 to the direction away from the mounting plate 122, and the fixing ring 121 is arranged at the end of the connecting rod 123 away from the mounting plate 122.

[0031] Further, the mounting plate 122 is provided with a plurality of first mounting holes 1221, and a plurality of mounting holes are arranged along the length direction of the mounting plate 122; the fixing base 110 is provided with a second mounting hole 111 corresponding to each of the first mounting holes 1221; and the mounting plate 122 and the fixing base 110 are fixedly connected through a threaded part penetrating through the first mounting hole 1221 and the second mounting hole 111.

[0032] In summary, the utility model discloses a kind of rammer compaction quantity observation devices 100, it includes fixing base 110, mounting bracket 120 and scale 130;Fixing base 110 is used in the lifting hook of rammer;Mounting bracket 120 is detachably connected with fixing base 110, mounting bracket 120 is provided with fixing ring 121 at the end away from fixing base 110, scale 130 is sleeved in fixed ring 121, and with fixed ring 121 sliding connection;The top of scale 130 is provided with limiting ring 131 above fixed ring 121.In rammer is beaten down after, lifting hook moves down and approaches rammer, when lifting hook and rammer are in slack state between, the bottom of scale 130 is in contact with the top of rammer, and the sliding connection of scale 130 and fixed ring 121 avoids that scale 130 and the top of rammer are damaged by hard contact.And when lifting hook is straightened to reach the position that rammer is about to be lifted, lifting hook and rammer are in taut state, the fixed ring 121 of this time abuts against limiting ring 131, and scale 130 is lifted off the surface of rammer again.Through such setting, when measurement is needed, scale 130 is in contact with the top of rammer, when measurement is not needed, scale 130 is separated from rammer, and the error of measurement is reduced.
