Description
Technical Field
The invention relates to the technical field of pipeline welding, in particular to a drainage PE pipeline hot-melt connection device and a connection method.
Background
In municipal drainage engineering or related underground pipeline construction processes, polyethylene (PE) drainage pipelines are widely adopted due to the advantages of corrosion resistance, light weight, convenience in construction and the like. When a pipeline is cracked and broken in construction, use or sudden accidents, the damaged position is usually cut off and then connected and repaired in a hot melting mode. The existing repair process generally comprises firstly cutting a long pipe section at two sides of a damaged part to ensure that the damaged part is thoroughly removed and a regular end face is obtained, then preparing a new pipe section with the same length as the cut pipe section, and completing connection through two thermal welding joints.
In conventional operation, a constructor typically first heat welds a joint to a new replacement pipe section and then welds the joint to the end of the side pipe to be joined. And then welding a second joint at the end part of the original pipeline at the other side, enabling the replaced new pipeline section to be inserted into the joint at the corresponding side, and finally enabling the two connected pipelines to be aligned in axis. However, since a new pipe section needs to be inserted into the joint, the pipe end cannot be fully inserted into the joint simply by means of alignment and translational pushing, and a certain angle of bending is required for the pipe, so that part of the allowance is released after bending deformation, and further, the pipe is inserted into place and is subjected to subsequent hot-melt welding.
However, in actual municipal drainage construction sites, the length of the trench formed by excavation is often limited by roads, ground structures and underground pipelines, and the trench working space is generally small. Meanwhile, the diameter of the PE pipeline for drainage is usually large, the pipe wall has certain rigidity, and effective bending is difficult to realize by constructors depending on manpower. If general tools such as a conventional crowbar and a wrench are used, not only is enough bending moment difficult to generate, but also the potential hazards of pipe wall indentation, surface damage or new hidden danger can be caused, the repairing efficiency is low and the risk of secondary damage exists.

Referring to fig. 2, a first driving member 500 is installed on the base frame 100 and is used to synchronously drive the pair of side frames 200 to rotate in opposite directions, so that the pipe ends clamped at both sides can deflect in opposite directions in the vertical direction. The first driving member 500 includes a pair of rotating wheels 510, a wheel belt 520 and a first driving motor 530, wherein the pair of rotating wheels 510 are respectively and fixedly connected to the side frames 200 on both sides in the vertical direction through a shaft 521, the shaft 521 is fixedly connected to the side frames 200 in the vertical direction, the wheel belt 520 is wound around the outer sides of the pair of rotating wheels 510, and the first driving motor 530 is fixedly arranged on the base frame 100 and is in transmission connection with one of the rotating wheels 510, thereby realizing synchronous and reverse rotation of the side frames 200 on both sides. In this embodiment, the rotating wheel 510 and the wheel belt 520 adopt a sprocket and chain structure, and have the advantages of reliable transmission and strong pollution resistance.
Of course, in other embodiments, the first driving member 500 may also adopt a synchronous belt mechanism, a gear transmission mechanism, or a motor disposed on each of the two side frames 200 for synchronous control, so long as the reverse linkage of the two side frames 200 can be achieved.
Referring to fig. 1, 5 and 6, a second driving member 600 is mounted on the side frame 200, and is used to drive the turret 300 to swing up and down about its hinge shaft, and to achieve position locking after swinging to a target position. Specifically, the second driving member 600 includes a second driving cylinder 610, where the second driving cylinder 610 is fixedly connected to the side frame 200 in a vertical direction, and a piston rod of the second driving cylinder is connected to the rotating frame 300, and drives the rotating frame 300 to rotate up or down around the hinge shaft under the telescopic action of the cylinder. The top of the base frame 100 is provided with an arc-shaped guide groove 110, and the cylinder body of the second driving cylinder 610 is connected in the guide groove 110 in a sliding manner, so that the second driving cylinder 610 can be adjusted in position along a predetermined track in the driving process, and interference caused by limited rotation is avoided. The guide groove 110 may take the form of a rail as shown in fig. 1, or may take the form of an arc-shaped catching groove formed at the top of the base frame 100.
The guide groove 110 is formed in an arc shape with the shaft 521 as a center, one end of the guide groove is located in a vertical plane where the shaft 521 of the side frames 200 is located, and the other end extends along a direction away from the vertical plane to form an arc segment, so that a movement track of the second driving cylinder 610 is effectively limited, and the rotating frame 300 is smoother and controllable in the up-and down-rotation process.
It should be emphasized that the connection device is particularly suitable for construction environments with shallow depth of the trench 900, limited vertical working space and insufficient rotating space of the rotating frame 300, such as emergency repair or partial excavation construction scenes of drainage pipelines under municipal roads. In the actual use process, the connecting device can be integrally pushed to the position of the pipeline to be repaired from the side edge of the groove 900 formed by excavation, and a large operation space is not required to be reserved right above the pipeline or secondary excavation expansion is not required.
The first driving part 500 drives the side frames 200 at two sides, so that the ends of the pipelines to be butted at two sides respectively rotate vertically and reversely rotate towards two sides of the groove 900, thereby forming sufficient transverse installation space between the pipelines, and then sequentially completing the installation and hot-melt welding of the first joint 810, the second joint 820 and the new pipe section 800, so that the whole butt joint process can be smoothly completed in a limited vertical space. The operation mode effectively avoids the problems that a welding head cannot enter due to insufficient upper space in traditional construction, the operation posture is limited and the like.
Of course, still need further to explain, if adopt traditional mode directly to treat the whole upward rotation of butt joint pipeline, then pipeline interface can be in upward inclination state, under this circumstances, the constructor when using the welding head to carry out the hot melt welding, must the gesture of artificial adjustment welding head in order to guarantee axiality as far as possible, not only the operation degree of difficulty is great, moreover because welding head self weight is great, hold easily to produce tiredly for a long time, only rely on the naked eye to correct the interface, the very easy axis skew of appearance or the inhomogeneous condition of welding seam, and then influence welding quality and later stage safety in utilization.
According to the invention, the pipeline to be butted is rotated towards the two sides of the groove 900, so that the pipeline joint can be in a basically horizontal state directly in the welding process, and the welding head is easier to maintain a stable posture and is naturally aligned with the axis of the pipeline under the action of gravity, thereby realizing more stable and accurate coaxial welding. The mode not only reduces the operation intensity of constructors, but also remarkably improves the welding consistency and the connection reliability, and effectively reduces welding defects and reworking risks.
As an alternative embodiment, the portion of the side frames 200 rotated at the base frame 100 is located at the edge position where the side frames 200 are spaced apart from each other, and the portion of the side frames 300 rotated at the side frames 200 is also located at the edge position where the side frames 200 are spaced apart from each other. With the above structural arrangement, a larger pipe offset can be obtained at the same rotation angle, thereby further improving the bending adjustment range of the pipe and providing more plentiful operation space for installing the new pipe section 800 and the first and second joints 810 and 820.
In order to realize the up-and-down rotation of the rotating frame 300, a fixing rod 340 is welded at a middle position of one end of the rotating frame 300, which is far away from the hinge joint of the rotating frame, a sliding sleeve 350 is sleeved on the fixing rod 340 in a sliding manner, and a piston rod of the second driving cylinder 610 is hinged with the sliding sleeve 350. In the process of driving the rotating frame 300 to rotate up or down by the second driving cylinder 610, the sliding sleeve 350 can slide along the direction of the fixed rod 340, so as to compensate the relative displacement in the moving process, avoid the clamping stagnation of the mechanism, and improve the smoothness and reliability of the overall movement.
Referring to fig. 5, the four corners of the base frame 100 are each provided with an adjusting assembly 700 for adjusting the height to accommodate complex construction conditions such as uneven, partial collapse or slope change of the bottom of the trench 900. Each adjusting component 700 comprises a sleeve 710, a sliding rod 720 and an adjusting screw 730, the sleeve 710 is fixedly welded on the base frame 100, the sliding rod 720 is inserted into the sleeve 710 in a manner of sliding up and down, the adjusting screw 730 is arranged along the length direction of the sleeve 710 and is in threaded connection with the sliding rod 720, the adjusting screw 730 is rotated to drive the sliding rod 720 to stretch vertically, so that the accurate adjustment of the height and the overall levelness of the base frame 100 is realized, the pipeline is ensured to be always in a stable and controllable posture in the clamping, rotating and hot melting butt joint processes, and adverse effects on welding coaxiality due to inclination of the base frame 100 are avoided.
Of course, in other alternative embodiments, the adjusting assembly 700 may also adopt an automatic adjusting structure, for example, the adjusting screw 730 is replaced by a vertically arranged adjusting cylinder or hydraulic cylinder, and the rapid automatic adjustment of the height of the base frame 100 is realized through a pneumatic or hydraulic driving manner, which is particularly suitable for the working condition that the height of the device needs to be frequently adjusted or the construction efficiency is high. Meanwhile, the bottom of the base frame 100 can be provided with a roller or universal wheel structure, when the base frame is not fixed, the whole device can be conveniently moved in the groove 900 or at the edge of the groove 900 for a short distance and accurately positioned, and after the device is positioned, the whole device is locked by a locking mechanism provided with the roller, so that the whole stability in the construction process is ensured.
Further, for improving the anti-overturning capability and the overall stability of the device during operation, the bottom of the base frame 100 may be further provided with a plug rod structure, wherein the plug rod can be inserted into the soil body or the cushion layer at the bottom of the groove 900 to form vertical and horizontal limit for the base frame 100, or in other embodiments, a push rod may be provided on the base frame 100, so that the push rod can extend out and abut against the side wall of the groove 900, thereby limiting the displacement and shaking of the base frame 100 during stress in a lateral supporting manner. The above-mentioned stabilization methods can be adopted independently or can be combined according to construction environments to adapt to different geological conditions and the forms of the grooves 900.
As an alternative embodiment, the base frame 100 may further be provided with a lifting lug 120, where the lifting lug 120 is used to connect with a lifting device, so as to integrally lift the entire connecting device into or out of the trench 900.
