[0002] At present, when repairing old pipelines, new repair pipes need to be transported to the construction site. New repair pipes are produced in the factory and wound onto a reel. After production is completed, the entire reel and the repair pipe are transported to the construction site together. The repair pipe is then dragged into the pipeline to be repaired by a winch. At the same time, special unwinding equipment is required to release the repair pipe rolled on the reel to reduce traction.

[0003] The current unwinding equipment is driven by a sprocket drive driven by a reducer installed on one side of the reel, and then the chain drive drives the sprocket on the reel shaft to realize the rotation of the reel, and finally releases the repair pipe belt on the reel according to the construction speed. This method has two defects. First, it is only supported by the mounting frames on both sides of the reel, which has certain requirements on the horizontality of the construction site. Second, because a reducer needs to be installed on one side of the reel, the reel protrudes extra in the width direction. The reel needs to be dismantled in advance during transportation and then installed at the construction site. For urban pipeline repair, it will increase the time of occupying public resources and reduce construction efficiency. Utility Model Content

The terms used in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention. The term "and / or" used herein includes any and all combinations of one or more related listed items.

[0030] like Figures 1 to 5 The repair pipe unwinding equipment shown includes: a driving end component 1, a supporting end component 2, a connecting plate 3, and a winding frame 4; the driving end component 1 is located at one end of the equipment, and the supporting end component 2 is arranged at the other end of the equipment, and is fixedly connected to the driving end component 1 through four connecting plates 3, and the winding frame 4 is coaxially arranged with the supporting end component 2 and is arranged on the inner side, wherein the driving end component 1 includes a reducer protective cover 11, a driving shaft 12, a reducer 13, a driving end side plate 14, a pin 15, and a driving end bearing seat assembly 16, the driving end bearing seat assembly 16 is fixedly connected to the driving end side plate 14 and the axes are arranged in a colinear manner, and the driving end bearing assembly 16 is sleeved on the middle section of the driving shaft 12.

[0031] The implementation process of the utility model requires that the drive end assembly 1 and the support end assembly 2 be assembled separately. When installing the drive end assembly 1, first fix the drive end bearing seat assembly 16 on the drive end side plate 14, then install the pin 15 on the plate welded to the drive shaft 12, then install the drive shaft 12 on the drive end bearing seat assembly 16, then install the reducer 13 on the drive shaft 12 and fix it to the drive end bearing seat assembly 16, and finally install the reducer protective cover 11 on the drive end side plate 14 to complete the installation of the entire drive end assembly 1; when installing the support end assembly 2, first install the support end bearing seat assembly 23 on the support end side plate 21, and then install the support shaft 22 on the support end bearing seat assembly 23 to complete the installation of the entire support end assembly 2.

[0032] When installing the unwinding device, first place the driving end assembly 1 on the ground and ensure that the detent pin 15 is at the highest point or the lowest point, then hoist the connecting plate 3, align one side of the connecting plate 3 with one of the mounting holes corresponding to the lower end of the driving end side plate 14 and tighten them, then hoist the other connecting plate 3, align one side of the connecting plate 3 with the other mounting hole corresponding to the lower end of the driving end side plate 14 and tighten them, then hoist the reel frame 4, align the support hole 42 in the middle of the reel frame 4 with the driving shaft 12, and at the same time align the running groove 41 on the reel frame 4 with the upper side of the driving end assembly 1 After the pin 15 is aligned, the roll rack 4 is inserted into the drive shaft 12, and then the lower ends of the roll rack 4 on both sides are supported with pads, and then the support end assembly 2 is hoisted, and the support shaft 22 of the support end assembly 2 is aligned with the roll rack support hole 42 and installed, and then the support end side plate 21 and the two installed lower end connecting plates 3 are bolted together, and finally the two connecting plates 3 on both sides of the upper end of the unwinding device are respectively installed, thereby completing the installation of the entire unwinding device. During subsequent installation and disassembly, the drive end assembly 1 and the support end assembly 2 do not need to be disassembled as a whole.

[0033] In the utility model, the reducer 13 is sleeved on one end of the outer side of the drive shaft 12 and is perpendicular to the axis of the drive shaft 12, which can effectively reduce the stress on the drive shaft 12, thereby extending the service life of the drive shaft 12. During operation, the drive shaft 12 needs to withstand a large amount of torque and impact force, and setting the reducer 13 perpendicular to the axis of the drive shaft 12 can disperse these forces to the reducer 13, thereby protecting the drive shaft 12 from damage. The reducer protective cover 11 is arranged on the outer side of the reducer 13 and is fixedly connected to the drive end side plate 14, which can effectively prevent dust, moisture and other impurities from entering the reducer, and avoid these substances from affecting the normal operation of the reducer 13. In addition, the reducer protective cover 11 can also prevent people's hands or other objects from contacting the operating reducer 13 to avoid accidental injuries.

[0034] In this solution, the pin 15 is arranged on the edge of the welding plate at one end of the inner side of the drive shaft 12, which can improve the bearing capacity and stability of the drive shaft 12, and also to better cooperate with the running groove 41 on the winding frame 4 to wind the repair tube.

[0035] In the embodiment of the utility model, the support end assembly 2 includes a support end side plate 21, a support shaft 22 and a support end bearing seat assembly 23. The support end bearing seat assembly 23 is installed in the center hole of the support end side plate 21, which is conducive to improving the bearing capacity of the equipment. Since the position of the center hole is exactly located at the maximum stress point of the support end side plate 21, the support end bearing seat assembly 23 is arranged here, which can effectively disperse the stress, reduce the fatigue damage of the equipment, and improve the bearing capacity of the equipment. The support end bearing seat assembly 23 is sleeved on the outer end of the support shaft 22 to further improve its stability and durability. The roll frame 4 is sleeved on the inner end of the support shaft 22 through the support hole 42, which can improve the stability of the equipment. Since the roll frame 4 is sleeved on the support shaft 22 through the support hole 42, even if the roll frame 4 is affected by external forces, it can maintain a relatively stable position. This design can effectively prevent the roll frame 4 from swinging and deflecting during operation, and ensure the stable operation of the equipment.

[0036] On the basis of the above, the pin 15 and the groove 41 of the reel 4 are installed correspondingly, which can effectively control the unwinding operation of the repair tube. At the same time, the connecting plate 3 is fixedly connected to the driving end assembly 1 and the supporting end assembly 2 by bolts, which can connect the devices at the left and right ends into a whole.

[0037] Those skilled in the art should understand that the present invention is not limited by the above embodiments. The above embodiments and the description are only for explaining the principle of the present invention. Without departing from the spirit and scope of the present invention, the present invention may have various changes and improvements, which are within the scope of the present invention.
