Description

Technical Field

[0001] The invention relates to the technical field of municipal construction, in particular to a municipal water supply and drainage pipe delivery method. Background Art

[0002] In the process of urbanization, municipal construction is becoming more and more high-quality. The construction of municipal water supply and drainage pipelines occupies an important position in the entire municipal engineering, and is a key project to ensure the development and construction of the city and the stable life of residents. At present, when laying pipes for municipal water supply and drainage, it is necessary to move the pipes manually or by hoisting; manual traction is labor-intensive and has low traction efficiency; the operation process of hoisting preparation, hoisting and moving, and lowering the pipes is cumbersome and has low traction efficiency; and in the process of pipeline transportation or on-site construction, there will be a process of assembling the pipeline with other pipelines or equipment. The above methods usually require manual positioning, which is difficult to locate.

[0003] In order to avoid the above problems, in view of this: Chinese patent CN108945948B discloses a pipe delivery device for municipal water supply and drainage, including a frame, at least one pair of conveying wheels fixed on the frame for clamping the pipe in the middle and driving the pipe to run in a straight line by rotation, a driving device for driving at least one conveying wheel and an adjusting device for adjusting the center distance of the conveying wheel pair; the center distance between each pair of conveying wheels of the present invention is adjustable and can be adapted to pipes of different diameters.

[0004] Although the above-mentioned method can achieve the effect of convenient pipeline transportation and adaptability to transportation with different pipe diameters, it is inevitable that there are still some shortcomings in the actual use process. For example, the device lacks an open storage mechanism, so that it is inconvenient to directly lower the pipeline from the top to the inside of the device, resulting in inconvenience in the initial placement of the pipeline. In order to avoid such problems, a municipal water supply and drainage pipe delivery method is proposed to solve the existing problems. Summary of the invention

[0005] In view of the deficiencies in the prior art, the present invention provides a municipal water supply and drainage pipe delivery method, which solves the problem that the pipes are inconvenient to be placed inside the device due to the lack of an open storage mechanism.

During the period when the deformation clamping mechanism drives the carrier plate to rise and stably clamps the pipe, the deformation clamping mechanism synchronously drives the self-transformation mechanism to operate. After the pipe is stably clamped, the upward movement stops and the movement is converted to forward and backward conveying movement. Step 4: Self-cleaning of dirt. When the self-transforming mechanism drives the deforming and pressing mechanism to change from up and down movement to forward and backward movement, the self-transforming mechanism and the deforming and pressing mechanism are driven to synchronously drive the self-cleaning mechanism to operate, so that the scraper in the self-cleaning mechanism synchronously cleans the dirt on the inner conical surface of the inner conical driving wheel to avoid the solidification of dirt and affect the stable transportation and use of the pipeline.

[0022] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0023] See also Figure 1-11 The present invention provides a technical solution: a municipal water supply and drainage pipe delivery method, which specifically includes the following steps: Step 1: placing the pipes on the inner conical surfaces of the multiple inner conical driving wheels 613 through the open space at the top of the carrying plate 2 in the mounting frame 1; Step 2: Gather and clamp, start the first electric telescopic rod 614 in the deformation and clamping mechanism 6, so that the carrier plate 2 carrying the pipe can rise, and synchronously drive the adjacent pressure rods 606 to gather and elastically press down, so that the pipe can be stably placed inside the multiple inner conical driving wheels 613. The first electric telescopic rod 614 starts its extended end to drive the carrier plate 2 to rise, and the carrier plate 2 drives the pipe to rise through the inner conical driving wheel 613. The rise of the carrier plate 2 synchronously drives the first tooth plate 610 to move, and the first tooth plate 610 synchronously meshes with the first gear 609 , the first gear 609 meshes with the second tooth plate 611, causing the second tooth plate 611 to move downward synchronously, and the second tooth plate 611 descends to drive the cross plate 601, the slide plate 602, the pressure rod 606, and the short rod 607 to descend, and the short rod 607 descends to squeeze and cooperate with the special-shaped guide rod 608. During the cooperation between the short rod 607 and the special-shaped guide rod 608, the two adjacent short rods 607 respectively carry the pressure rod 606 to gather together, causing the two adjacent pressure rods 606 to merge and continue to descend until the pressure rod 606 presses the pipeline tightly; Step 3, drive conversion, the deformation clamping mechanism 6 drives the bearing plate 2 to rise and promotes the stable clamping of the pipeline. The deformation clamping mechanism 6 synchronously drives the self-transforming mechanism 7 to operate, and the pipeline after stable clamping stops rising and turns to forward and backward conveying movement. When the pressure rod 606 contacts the top of the pipeline, the inner conical driving wheel 613 and the pressure rod 606 still run in reverse up and down. When the inner conical driving wheel 613 and the pressure rod 606 continue to run in reverse, the sliding sleeve 9 and the sliding rod 10 connected to the pressure rod 606 will jointly carry the sliding block 603 to the second return spring 604 inside the slide groove plate 602 for The elastic compression is performed until the top of the sliding block 603 abuts against the bottom of the limit stop plate 706. When the right front sliding block 603 is compressed toward the second return spring 604, the right front sliding block 603 synchronously drives the insertion rod 704 to rise, and the insertion rod 704 drives the pressing plate 705 to press and trigger the stop button 702 and the start button 703 synchronously. The stop button 702 is stressed and the first electric telescopic rod 614 stops running and retains the existing telescopic height. After the start button 703 is stressed, the servo motor 5 is started, and the servo motor 5 synchronously drives the front rotating rod 4 and the inner conical driving wheel 613 to transport the clamped pipe forward and backward. Step 4, self-cleaning of mud and dirt. When the self-transforming mechanism 7 drives the deformation and clamping mechanism 6 to change from up and down movement to forward and backward movement, the self-transforming mechanism 7 and the deformation and clamping mechanism 6 are driven to synchronously drive the self-cleaning mechanism 8 to operate, so that the scraper 804 in the self-cleaning mechanism 8 synchronously cleans the mud and dirt on the inner cone surface of the inner conical driving wheel 613 to avoid mud and dirt solidification and affecting the stable transportation of the pipeline. When the servo motor 5 drives the front rotating rod 4 to operate, the front rotating rod 4 synchronously drives the pulley 801 to rotate, and the rotation of the pulley 801 is coordinated with the belt 802 to drive the rear rotating rod 4 and the inner conical driving wheel 613 to rotate synchronously accordingly. During the rotation of the rotating rod 4, the second gear 805 is synchronously driven to rotate. The rotation of the second gear 805 will mesh with the adjacent third gear 806, prompting the third gear 806 to drive the rotating shaft 803 and the scraper 804 to rotate. The rotation of the scraper 804 will clean the mud and dirt on the inner cone surface of the rotating inner conical driving wheel 613.
