Description

Technical Field

[0001] The invention relates to the technical field of road construction, and in particular to a pipeline hoisting device and method for municipal road construction. Background Art

[0002] Municipal road pipeline construction is an important part of urban infrastructure construction, involving the installation and maintenance of various pipelines such as water supply, drainage, gas supply, electricity and communication. When carrying out municipal road pipeline construction, it is necessary to lay the pipelines. Laying requires the use of lifting equipment to lift the pipelines, transport the pipelines to the laying location and perform docking and installation;

[0003] Traditional municipal road pipeline construction lifting methods mostly use cranes for lifting. Positioning ropes are used to manually position the two ends of the pipeline. After positioning is completed, the pipeline is lifted to the laying position by a crane for precise docking and laying, and all pipeline center lines are aligned. It is necessary to adjust the angle of the pipeline when manually positioning the pipeline with the positioning rope. Then, the positioning rope is manually removed, and the next pipeline is positioned, lifted and laid. This method requires manual precise positioning, resulting in relatively slow overall efficiency and certain safety hazards. Secondly, the overall size of the crane is large, and it needs to travel back and forth to lift and dock the pipeline to be laid, which is troublesome and wastes work travel.

[0015] A method for using a pipeline lifting device for municipal road construction comprises the following steps:

[0016] Step 1: Use the crawler wheel walking mechanism to move the entire pipeline lifting device above the pipeline pit, and move the transport vehicle with the pipeline directly onto the mobile base through the vehicle platform, so as to facilitate the direct lifting of the pipeline on the mobile base;

[0017] Step 2, control the linear electric rail to drive the installation bracket and the lifting mechanism to slide horizontally, so as to adjust the position of the lifting mechanism, and at the same time, control the first motor to drive the rotating longitudinal column to rotate horizontally, so as to control the sleeve frame, the connecting sliding frame and the top clamp and the bottom clamp to rotate horizontally, and then adjust the angles of the top clamp and the bottom clamp until the top clamp and the bottom clamp are stably inserted into one end of the pipe, and then control the fourth motor to drive the pitch adjusting screw to rotate, cooperate with the pitch adjusting screw thread to penetrate the pitch adjusting screw barrel, drive the bottom clamp to slide vertically on the outside of the guide longitudinal rod, adjust the distance between the top clamp and the bottom clamp, so that one end wall of the pipe is clamped between the top clamp and the bottom clamp for positioning, at this time, the outer wall of one end of the pipe contacts the outer wall of the ball bearing and the adjusting roller in the top clamp, and the inner wall of one end of the pipe contacts the outer wall of the ball bearing and the adjusting roller in the bottom clamp;

[0018] Subsequently, the second motor is controlled to start driving the translation shaft to rotate, thereby controlling the translation gear to rotate, cooperating with the translation gear and the translation rack to mesh and connect, driving the connecting slide frame to translate on the connecting transverse frame, so that the connecting slide frame translates to the other end of the connecting transverse frame. At this time, the connecting slide frame is located in the middle of the pipeline to prevent the pipeline from tilting when lifting the pipeline;

[0019] Step 3: Control the wire rope traction machine to drive the wire rope body to reel up, thereby controlling the clamping mechanism to move up and lift the pipeline, and then control the linear electric rail to drive the installation bracket and the lifting mechanism to slide horizontally and lift the pipeline to the top of the feeding chute;

[0020] When the angle position of the pipeline needs to be adjusted so that the positioning lines of the outer walls of adjacent pipelines correspond, the third motor in the top clamp and the bottom clamp is directly controlled to drive the adjustment horizontal axis and the adjustment roller to rotate, thereby controlling the pipeline to roll between the top clamp and the bottom clamp, and automatically adjusting the position of the positioning line of the outer wall of the pipeline;

[0021] Step 4: Control the opening of the wire rope traction machine to drive the wire rope body to unwind, thereby controlling the clamping mechanism to move downward, thereby controlling the hoisted pipe to move downward through the feed chute to the pipe pit, and accurately docking and installing the pipe at the end of the previous pipe through horizontal movement;

[0022] Step 5: Control and start the fourth motor again to drive the pitch-adjusting screw to rotate in the opposite direction, so that the pitch-adjusting screw thread penetrates the pitch-adjusting screw barrel, drives the bottom clamp to slide vertically on the outside of the guide longitudinal rod, and adjusts the distance between the top clamp and the bottom clamp, so that the pipeline loses its positioning;

[0023] Subsequently, the second motor is controlled to be turned on again to drive the translation shaft to rotate in the opposite direction, thereby controlling the translation gear to rotate in the opposite direction, cooperating with the translation gear and the translation rack to engage and connect, driving the connecting slide frame to translate in the opposite direction on the connecting cross frame, so that the connecting slide frame translates to one end of the connecting cross frame. At this time, the connecting slide frame is located in the middle position of the entire clamping mechanism, which is convenient for the clamping mechanism to translate stably and prevents the clamping mechanism from being offset from the center and tilted when it is translated in an empty manner, so as to facilitate the lifting and installation of the next pipeline.

[0024] Compared with the prior art, the present invention has the following beneficial effects:

[0025] 1. By setting up a lifting mechanism, the pipeline can be automatically clamped and positioned, and the pipeline can be stably lifted to prevent the pipeline from tilting and rotating. It is also convenient to adjust the angle position of the pipeline so that the pipeline can be automatically and accurately docked, thereby improving the lifting and installation efficiency of the pipeline.

[0026] 2. By setting up a loading platform, the transport vehicle for placing the pipeline can be directly moved up to the mobile base through the loading platform, so that the pipeline can be directly lifted on the mobile base. There is no need to drive back and forth to lift and connect the pipeline to be laid, thus reducing the work trip. BRIEF DESCRIPTION OF THE DRAWINGS

The top clamp 45 is fixedly installed at the bottom end of the connecting longitudinal frame 441 through the top end of the clamping transverse frame 461. The end of the clamping transverse frame 461 in the bottom clamp 46 away from the connecting longitudinal frame 441 is movably inserted with a guide longitudinal rod 47.

At this time, the outer wall of one end of the pipe contacts the outer wall of the ball 462 and the adjusting roller 463 in the top clamp 45, and the inner wall of one end of the pipe contacts the outer wall of the ball 462 and the adjusting roller 463 in the bottom clamp 46;

[0053] Subsequently, the second motor 434 is controlled to start driving the translation shaft 433 to rotate, thereby controlling the translation gear 432 to rotate, cooperating with the translation gear 432 and the translation rack 442 to mesh and connect, driving the connecting slide frame 43 to translate on the connecting horizontal frame 44, so that the connecting slide frame 43 translates to the other end of the connecting horizontal frame 44.

[0055] When the angle position of the pipeline needs to be adjusted so that the positioning lines of the outer walls of adjacent pipelines correspond, the third motor 465 in the top clamp 45 and the bottom clamp 46 is directly controlled to drive the adjustment horizontal shaft 464 and the adjustment roller 463 to rotate, thereby controlling the pipeline to roll between the top clamp 45 and the bottom clamp 46, and automatically adjusting the position of the positioning line of the outer wall of the pipeline;

[0056] Step 4: Control the opening of the wire rope traction machine 31 to drive the wire rope body 32 to unwind, thereby controlling the clamping mechanism 4 to move downward, thereby controlling the hoisted pipe to move downward through the feed chute to the pipe pit, and accurately docking and installing the pipe at the end of the previous pipe through horizontal movement;

[0057] Step 5: Control and start the fourth motor 482 again to drive the pitch-adjusting screw 48 to rotate in the opposite direction, so that the pitch-adjusting screw 48 passes through the pitch-adjusting screw barrel 481, and drives the bottom clamp 46 to slide vertically on the outside of the guide longitudinal rod 47, and adjusts the distance between the top clamp 45 and the bottom clamp 46, so that the pipeline loses its position;

[0058] Subsequently, the second motor 434 is controlled to be turned on again to drive the translation shaft 433 to rotate in the opposite direction, thereby controlling the translation gear 432 to rotate in the opposite direction, cooperating with the meshing connection of the translation gear 432 and the translation rack 442, driving the connecting slide frame 43 to translate in the opposite direction on the connecting cross frame 44, so that the connecting slide frame 43 translates to one end of the connecting cross frame 44. At this time, the connecting slide frame 43 is located in the middle position of the entire clamping mechanism 4, which is convenient for the clamping mechanism 4 to translate stably, and prevents the clamping mechanism 4 from being offset from the center and tilted when it is translated in the air, so as to facilitate the lifting and installation of the next pipeline.
