Description

Technical Field

[0001] The invention relates to the technical field of municipal manhole construction, in particular to a manhole construction compactor for municipal engineering and a construction method. Background Art

[0002] When the municipality constructs a manhole, a gravel or concrete foundation is laid at the bottom of the excavated pit to ensure the stability of the manhole, and prefabricated manhole rings, covers, etc. are installed on the foundation. After installation, the driver needs to drive a compactor to compact the ground around the manhole.

[0003] In the patent document with application number CN202111277230.9, a pressure-adjustable vertical rotary compactor for municipal manhole construction is disclosed, including a rolling assembly, a drive assembly, a push-pull hydraulic cylinder and a support frame; the push-pull hydraulic cylinder is arranged at the top of the support frame, the output end of the push-pull hydraulic cylinder is connected to the drive assembly, and the drive assembly is connected to the rolling assembly. Eight groups of 28 static rolling steel wheels are used to roll the periphery of the manhole. The installation positions of the three rolling wheels in a group of three wheels correspond to the three gaps between the four rolling wheels in a group of four wheels. In the specific use process, the manhole construction compactor usually drives the tamping disc to compact the ground around the manhole through a hydraulic cylinder. Although the compaction effect is good, the soil on the surface of the ground will be scattered by the huge impact force generated when it is compacted, resulting in the need for manual compaction of the surface soil to make it denser for the next step of construction.

[0015] A construction method of a manhole construction compactor for municipal engineering, comprising the following steps:

[0016] S1: The driver drives the compactor body to the manhole construction site, aligns the compacting plate with the ground around the manhole, and then controls the hydraulic cylinder to drive the compacting plate to move back and forth to compact the ground;

[0017] S2: After several tampings, the tamping operation is stopped, and the compacting machine body is continued to be moved so that the roller is aligned with the ground around the manhole, and then the electric push rod is controlled to work, and the electric push rod drives the connecting rod and the mounting rod to move downward, and then the roller, the roller shaft and the support part can be driven to move downward through the cover frame and the insertion rod. At this time, the guide part also drives the sleeve to move downward, so that the telescopic spring is stretched until the roller is squeezed on the ground and stops;

[0018] S3: At this time, the motor is turned on again, so that the driving gear drives the driven gear plate to rotate, so that the electric push rod rotates on the support bearing, and then drives the cover frame to rotate. Since the insertion rod is inserted on the support block, when the cover frame rotates, the guide rod rotates in the guide rail, so that the outer ring and the inner ring can drive the support block to rotate accordingly, thereby driving the roller to move circumferentially on the ground;

[0019] S4: While moving, the roller will rotate between the semicircular groove and the semicircular through groove, so that the roller can rotate and move in a circumferential direction, thereby compacting the scattered ground surface soil and completing the compaction work of the ground around the manhole.

[0020] Compared with the prior art, the beneficial effects of the present invention are as follows: the connecting rod and the mounting rod are driven downward by the electric push rod, and then the roller, the roller shaft and the supporting part are driven downward by the cover frame and the insertion rod. At this time, the guide part also drives the sleeve to move downward, so that the telescopic spring is stretched until the roller is squeezed on the ground and stops. At this time, the motor is turned on again, so that the driving gear drives the driven gear plate to rotate, so that the electric push rod rotates on the supporting bearing, and then drives the cover frame to rotate. Since the insertion rod is inserted into the supporting block, when the cover frame rotates, the guide rod rotates in the guide rail, so that the outer ring and the inner ring can drive the supporting block to follow As it rotates, the roller is driven to move in a circumferential direction on the ground. While moving, the roller shaft will rotate between the semicircular groove and the semicircular through groove, so that the roller can move in a circumferential direction while rotating, so that the scattered ground surface soil can be compacted. The ground around the manhole can be effectively compacted by compacting it first with a tamping disk and then with a roller. The roller shaft of the roller rotates between the semicircular groove and the semicircular through groove, and there is no need to set a bearing that matches the roller shaft. Therefore, when the roller is pressed to the ground, the extrusion force will not act on the bearing, and there is no need to replace the bearing. When maintaining the roller, the cover part can be removed from above the support block, which is more convenient. BRIEF DESCRIPTION OF THE DRAWINGS

Therefore, when the roller 25 is pressed to the ground, the extrusion force will not act on the bearing, and there is no need to replace the bearing. While providing a fixing effect on the roller 25, and when maintaining the roller 25, the cover part 24 can be moved away from the top of the support block 274, which is more convenient.

[0038] The support part 27 includes an outer ring 271 and an inner ring 272. The inner ring of the outer ring 271 is evenly provided with a fixing rod 273 connected to the inner ring 272, so that the outer ring 271 and the inner ring 272 can be connected together. The heights of the outer ring 271, the inner ring 272 and the fixing rod 273 are all higher than the bottom of the roller 25, so that when contacting the ground, only the roller 25 can contact, and the bottom of the roller 25 is aligned with the bottom of the tamping disk 13, which is convenient for controlling the electric push rod 222 to drive the connecting rod 231 to move the same distance as the tamping disk 13. The outer ring 271 Support blocks 274 are evenly arranged on the top of the inner ring 272, and semicircular grooves in contact with the front and rear ends of the roller shaft 26 are opened on the opposite sides of the support blocks 274 on the outer ring 271 and the inner ring 272.

When the roller 25 is not in use, the guide rail 282 drives the support part 27 to automatically reset, so that the roller 25 can automatically move upward and reset.

[0041] Example 2

[0042] Reference Figure 1 In order to improve the stability of the tamping plate 13 when it moves, vertical rods 14 that can be slidably connected to the tamping plate 13 are evenly arranged on the top inner wall of the fixed cover 11.

[0043] The rest of the structure is the same as that of Example 1.

[0044] A construction method of a manhole construction compactor for municipal engineering, comprising the following steps:

[0045] S1: The driver drives the compactor body to the manhole construction site, aligns the compacting plate 13 with the ground around the manhole, and then controls the hydraulic cylinder 12 to drive the compacting plate 13 to move back and forth to compact the ground;

[0046] S2: After several tamping operations, the tamping operation is stopped, and the compacting machine body is continued to be moved so that the roller 25 is aligned with the ground around the manhole, and then the electric push rod 222 is controlled to work, and the electric push rod 222 drives the connecting rod 231 and the mounting rod 232 to move downward, and then the roller 25, the roller shaft 26 and the supporting part 27 can be driven to move downward through the cover frame 241 and the insertion rod 243. At this time, the guide part 28 also drives the sleeve 291 to move downward, so that the telescopic spring 294 is stretched, until the roller 25 is squeezed on the ground and stops;

[0047] S3: At this time, the motor 212 is turned on again, so that the driving gear 213 drives the driven gear plate 223 to rotate, so that the electric push rod 222 rotates on the support bearing 221, and then drives the cover frame 241 to rotate. Since the insertion rod 243 is inserted on the support block 274, when the cover frame 241 rotates, the guide rod 281 rotates in the guide rail 282, so that the outer ring 271 and the inner ring 272 can drive the support block 274 to rotate accordingly, thereby driving the roller 25 to move circumferentially on the ground;

[0048] S4: While moving, the roller shaft 26 will rotate between the semicircular groove and the semicircular through groove 242, so that the roller 25 can rotate and move in a circular direction, thereby compacting the scattered ground surface soil and completing the compaction work of the ground around the manhole.
