Description

Technical Field

[0001] The utility model relates to a municipal pipeline lifting and docking device, belonging to the field of municipal engineering. Background Art

[0002] In municipal engineering, the laid pipes need to be butt-jointed to connect several sections of pipes into a complete pipeline. The butt-jointing work of the pipes includes fixing, adjusting, aligning holes and reinforcing procedures. This series of work is completed manually. However, the length of each section of the pipe is relatively long. Therefore, it takes a lot of physical strength to control the pipe ports. Moreover, only when the axis lines of the two pipes are in the same vertical line can the two pipes be easily butt-jointed. Even if there is a slight angle deviation, it will be difficult to achieve butt-jointing. Therefore, the manual precise positioning method obviously has great shortcomings.

[0003] However, the pipeline trenches for laying existing municipal pipelines are excavated manually or by manually operated equipment, which easily causes the bottom of the pipeline trench to be uneven. In this way, when the docking device is placed in the pipeline trench, the flatness of each position of the docking device in the pipeline trench is different, and the docking device cannot maintain a horizontal state during the pipeline installation process.

[0036] When in use, the extension distance of the four support rods 14 is adjusted according to the flatness of the pipeline groove, so that the device is in a horizontal state.

[0037] That is, when it is necessary to adjust the extension distance of a certain support rod 14, the motor 22 at the corresponding position is started, and the motor 22 drives the screw rod 19 and the gear 23 to rotate. At this time, the rack plate 25 has not yet risen to contact the gear 23, and the rotation of the gear 23 is in an idling state.

[0038] When it is necessary to drive the two support rods 14 on the same side, at this time, the above-mentioned actions are repeated, except that the inclined plane seat 21 on one side is moved to the inclined plane end of the middle inclined plane block 7, and then the rack plate 25 is raised, and the rack plate 25 is raised to mesh with the gear 23, and then the motor 22 is driven. The motor 22 drives the inclined plane seat 21 to move in the direction of the inclined plane sliding member through the meshing of the gear 23 and the rack plate 25, and then squeezes and pushes the middle inclined plane block 7, so that the middle inclined plane block 7 descends, and the middle inclined plane block 7 pushes the two end inclined plane blocks 8 to descend by pressing the fitting groove 12 and the fitting protrusion 13, and then pushes the support rods 14 and the foot plate 15 at the bottom of the two end inclined plane blocks 8 to descend, so that the two side support rods 14 on the same side are lowered, and then the base 1 is adjusted to a horizontal state;

[0039] When the four support rods 14 on both sides need to be driven, the above actions are repeated, except that the inclined plane seats 21 on both sides are moved to the inclined plane ends of the middle inclined plane block 7, and then the above actions are repeated to realize the lowering of the support rods 14 on both sides, thereby adjusting the base 1 to a horizontal state;

[0040] When the device is in use, the support wheel 5 is used to pull the device to move inside the pipeline groove. After moving to the specified position, the horizontality of the device is adjusted by the leveling mechanism. After the adjustment is completed, the height of the clamp 4 is adjusted by the cylinder 2 so that the end clamp 4 is docked with the end of the previously installed pipe. After the docking is completed, the clamp 4 is locked. At this time, the three clamps 4 are on the same horizontal axis. Then, the new pipe is installed in the other two empty clamps 4. At this time, the two pipes are on the same axis, thereby realizing docking installation.
