Description

Technical Field

[0001] The invention relates to the technical field of ultraviolet light curing and repairing pipelines, and in particular to an auxiliary transmission device used for ultraviolet light curing and repairing. Background Art

[0002] With the acceleration of urbanization, the maintenance and repair of underground pipeline networks, as the "lifeline" of cities, has become increasingly important. UV curing technology has been widely used in the field of pipeline repair. The repair material impregnated with photosensitive resin is cured by ultraviolet light, which can effectively repair damaged pipelines.

[0003] Specifically, the hose lining for repair is impregnated with resin and pulled into the municipal pipeline, and the hose lining is expanded and fits the inner wall of the municipal pipeline to be repaired by using an inflation device. Then the UV repair device is pulled into the hose lining and the device is slowly moved along the inner wall of the hose lining by traction. The UV lamp on the UV repair device follows the movement, and the UV light emitted solidifies the resin on the hose lining, so that the hose lining fits and fixes with the inner wall of the municipal pipeline, thereby achieving the effect of municipal pipeline repair.

[0004] The existing method of moving the UV repair equipment in the pipeline by pulling it with a cable is feasible, but it has significant defects. In a complex pipeline layout, when there are bends and branch pipelines, the UV repair equipment without a limit is easy to collide with the pipe wall during the pulling process, causing damage to the lamp.

[0005] For example, in actual operation, pipelines generally consist of vertical sections and horizontal sections. When repairing, the equipment needs to be lowered from the upper opening of the vertical section through the vertical section to the horizontal section to be repaired. Due to the lack of effective limiting means, the equipment shakes during the lowering process and is prone to collide with the inner wall of the vertical section, causing damage to components such as lamps on the equipment, increasing repair costs and construction time. Summary of the invention

[0006] The technical problem to be solved by the present invention is to provide an auxiliary conveying device for UV curing repair, which uses a limiting cylinder to perform limiting constraints during the process of lowering the UV repair equipment to avoid collision and damage between the UV repair equipment and the inside of the pipeline.

[0007] In response to the above technical problems, the technical solution provided by the present invention is an auxiliary transmission device for UV light curing repair, comprising a hollow top cover, wherein the hollow top cover is used to cover the upper end opening of the vertical section, and a limiting cylinder is coaxially arranged below the hollow top cover, and the outer wall of the limiting cylinder is used to be attached to the inner tube wall of the vertical section, and the inner cavity of the limiting cylinder is used to adapt to the size of the UV light repair equipment, and a sliding mechanism is arranged between the limiting cylinder and the hollow top cover, and the sliding mechanism is used to drive the limiting cylinder to slide along the axial direction of the vertical section to approach and move away from the hollow top cover.

[0008] Further, the sliding mechanism includes a driving screw, the lower end of the driving screw is rotationally matched with the upper end of the limiting cylinder, the upper end of the driving screw passes through the hollow top cover upward, and the driving screw is threadedly matched with the hollow top cover.

[0009] Further, the limiting cylinder includes a first limiting cylinder, a second limiting cylinder and a supporting vertical plate, the first limiting cylinder and the second limiting cylinder are arranged at intervals along the axis of the limiting cylinder, the supporting vertical plate connects the first limiting cylinder and the second limiting cylinder, and the interval between the first limiting cylinder and the second limiting cylinder is used to be smaller than the length of the ultraviolet light repair equipment.

[0010] Furthermore, a reversing mechanism is provided on the hollow top cover, and a guide assembly is provided at the lower end of the limiting cylinder. The reversing mechanism is used to drive the hollow top cover to rotate, so as to drive the guide assembly to rotate, and the guide assembly is used to guide the solidified repair material to the horizontal section to be repaired.

[0011] Furthermore, an annular gap is arranged between the outer side surface of the hollow top cover and the outer wall of the vertical section, and the reversing mechanism includes a rolling wheel and a driving mechanism. A plurality of rolling wheels are arranged at equal intervals within the annular gap, and the outer periphery of the rolling wheel is used to be attached to the outer wall of the vertical section. The driving mechanism is used to drive the rolling wheel to roll along the outer periphery of the vertical section in a circular direction to rotate the hollow top cover.

[0012] Furthermore, the rotating shaft of the rolling wheel extends upward and extends out of the hollow top cover, and the driving mechanism includes a driving gear, an inner gear ring and a driving motor. The upper end of each rotating shaft is fixed with a driving gear, and the inner gear ring is rotatably installed on the upper end of the hollow top cover. Each driving gear is meshed with the internal teeth of the inner gear ring for transmission, and the driving motor drives one of the rotating shafts to rotate.

[0013] Furthermore, an inverted L-shaped supporting top plate is fixedly mounted on the hollow top cover at a position corresponding to the driving motor, and the upper end of the driving motor is fixedly mounted on the lower side surface of the transverse section of the supporting top plate.

[0014] Furthermore, the rolling wheel includes an inner roller and a plurality of rubber pad layers evenly arranged on the outer surface of the roller, and adjacent rubber pad layers are arranged at intervals.

[0015] Furthermore, the guide assembly includes a support frame arranged at the lower end of the limiting cylinder, and a guide roller rotatably arranged on the support frame, and the rotation axis of the guide roller extends in the horizontal direction.

[0016] Compared with the prior art, the beneficial effects of the present invention are:

[0017] (1) The hollow top cover allows the UV repair equipment to enter the vertical section, and the inner cavity of the limit cylinder can provide a stable constraint for the movement of the UV repair equipment. When the UV repair equipment is lowered, the limit cylinder moves downward synchronously under the action of the sliding mechanism, always protecting the UV repair equipment and preventing it from directly colliding with the inner wall of the pipeline. At the same time, the inner cavity of the limit cylinder is adapted to the size of the UV repair equipment, which can further reduce the risk of shaking of the UV repair equipment and the risk of damage to the lamp. At the same time, it prevents secondary damage to the pipeline caused by the shaking of the lamp and the impact on the pipe wall, ensuring that the ultraviolet rays evenly and efficiently irradiate the repair material, greatly improving the repair quality.

[0018] (2) The lower end of the driving screw is rotatably mounted on the limit cylinder, and the upper end extends out of the hollow top cover and cooperates with the thread of the hollow top cover. During the rotation of the driving screw, the limit cylinder can be driven to slide in the vertical section. At the same time, the driving screw is used to drive the sliding, which has a smaller volume and lighter weight on the one hand, and can ensure the smooth sliding process of the limit cylinder on the other hand.

[0019] (3) The use of the reversing mechanism greatly facilitates the operator to flexibly adjust the direction of the guide component according to the different pipeline directions and repair requirements. It is not only conducive to the transmission of the UV repair equipment, but also convenient for the layout of the base film and hose, reducing the difficulty of operation and time consumption, and improving construction efficiency. When the base film hose enters the pipeline, the guide component can ensure that the hose moves smoothly and steadily along the predetermined path, avoiding bending, entanglement, etc., so that it can fit closely to the inner wall of the pipeline, creating good conditions for the subsequent laying of repair materials, and further improving the efficiency and quality of the entire pipeline repair work.

DETAILED DESCRIPTION

[0027] In order to make the purpose, technical solution and advantages of the embodiments of the present application clearer, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present application: Specific embodiment 1:

[0029] In this embodiment, if Figure 1 As shown, the pipeline 1 includes a vertical section 101 and a horizontal section 102. The horizontal section 102 is the section to be repaired. In actual use, the ultraviolet light repair equipment and corresponding repair materials need to be lowered from the upper end opening of the horizontal section 102 into the vertical section 101, and then enter into the horizontal section 102 to complete the repair work.

[0030] refer to Figures 1 to 6 The present invention provides an auxiliary conveying device for UV curing repair (hereinafter referred to as conveying device), including a hollow top cover 2, which is used to cover the upper end opening of the vertical section 101, and the inner ring size of the hollow top cover 2 is not less than the annular size of the UV repair equipment, so that the UV repair equipment and other repair materials can pass through.

[0031] A limiting cylinder 19 is coaxially arranged below the hollow top cover 2. The outer wall of the limiting cylinder 19 is used to be attached to the tube wall inside the vertical section 101. The inner cavity of the limiting cylinder 19 is adapted to the size of the ultraviolet light repairing device, and can limit the radial limit of the ultraviolet light repairing device. A sliding mechanism is arranged between the limiting cylinder 19 and the hollow top cover 2, and the limiting cylinder 19 and the hollow top cover 2 are connected by the sliding mechanism. The sliding mechanism is used to drive the limiting cylinder 19 to slide along the axial direction of the vertical section 101 to approach and move away from the hollow top cover 2.

[0032] Such a setting utilizes the hollow top cover 2, so that the ultraviolet light repair equipment can enter the vertical section 101, and the inner cavity of the limiting cylinder 19 can provide a stable constraint for the movement of the ultraviolet light repair equipment. When the ultraviolet light repair equipment is lowered, the limiting cylinder 19 moves downward synchronously under the action of the sliding mechanism, always protecting the ultraviolet light repair equipment from direct collision with the inner wall of the pipeline 1. At the same time, the inner cavity of the limiting cylinder 19 is adapted to the size of the ultraviolet light repair equipment, which can further reduce the risk of shaking of the ultraviolet light repair equipment and the risk of damage to the lamp. At the same time, it prevents secondary damage to the pipeline 1 caused by the shaking of the lamp and the impact of the pipe wall, ensuring that the ultraviolet light evenly and efficiently irradiates the repair material, greatly improving the repair quality.

[0033] Preferably, in this embodiment, Figure 1 , 2 As shown, the sliding mechanism includes a driving screw 3, the lower end of the driving screw 3 is rotationally matched with the upper end of the limiting cylinder 19, the upper end of the driving screw 3 passes through the hollow top cover 2 upward, and the driving screw 3 is threadedly matched with the hollow top cover 2.

[0034] In this way, the lower end of the driving screw 3 is rotatably installed on the limit cylinder 19, and the upper end extends out of the hollow top cover 2 and is threadedly matched with the hollow top cover 2. During the rotation of the driving screw 3, the limit cylinder 19 can be driven to slide in the vertical section 101. At the same time, the driving screw 3 is used to drive the sliding. On the one hand, the sliding mechanism is small in size and light in weight. On the other hand, it can ensure that the sliding process of the limit cylinder 19 is smooth.

[0035] Of course, in other embodiments, when the actual use requirements are met, the sliding mechanism can also be a sliding rod, the lower end of the sliding rod is fixed to the upper end of the limiting cylinder 19, and a through hole matching the sliding rod is provided on the hollow top cover 2. The sliding rod slides through the through hole, and the limiting cylinder 19 can be driven to slide along the axial direction of the vertical section 101 by the sliding rod. At the same time, a plurality of pin holes are arranged at intervals along the length direction of the sliding rod, and the sliding mechanism also includes a positioning pin matching the pin hole. After the sliding is completed, the positioning pin is inserted into the corresponding pin hole and then cooperates with the upper end of the hollow top cover 2 to achieve the fixing of the sliding rod.

[0036] In this embodiment, preferably, the limiting cylinder 19 includes a first limiting cylinder 5, a second limiting cylinder 6 and a supporting vertical plate 4, wherein the first limiting cylinder 5 and the second limiting cylinder 6 are arranged at intervals along the axis of the limiting cylinder 19, the supporting vertical plate 4 connects the first limiting cylinder 5 and the second limiting cylinder 6, and the upper end of the supporting vertical plate 4 extends out of the first limiting cylinder 5 and the lower end extends out of the second limiting cylinder 6, and the outer side surface of the supporting vertical plate 4 is an arc-shaped surface adapted to the inner wall of the vertical section 101 and is crimped onto the inner wall of the vertical section 101.

[0037] The cross-sections of the first limiting cylinder 5 and the second limiting cylinder 6 are both annular, and the interval between the two is used to be smaller than the length of the ultraviolet light repairing device. The lower end of the driving screw 3 is rotatably arranged at the upper end of the supporting vertical plate 4. In this way, by utilizing the interval between the first limiting cylinder 5 and the second limiting cylinder 6, it can be ensured that when the ultraviolet light repairing device is transmitted between the first limiting cylinder 5 and the second limiting cylinder 6, it can be simultaneously in contact with the first limiting cylinder 5 and the second limiting cylinder 6, thereby ensuring its stability, saving volume and weight, and facilitating the operation of the sliding mechanism.

[0038] Specifically, in the present embodiment, the top and bottom of the first limiting tube 5 and the second limiting tube 6 are both rounded to reduce friction. At the same time, the first limiting tube 5 and the second limiting tube 6 are injection molded with engineering plastics and have smooth inner and outer surfaces, and have the characteristics of light weight, wear resistance, and low friction coefficient. In this way, when the ultraviolet light repair equipment collides slightly with the inner wall of the first limiting tube 5 and the second limiting tube 6, the engineering plastic can absorb and buffer the collision energy through its own deformation, thereby reducing the impact force on the ultraviolet lamp and reducing the possibility of damage. The inner wall surfaces of the first limiting tube 5 and the second limiting tube 6 are smoothed to reduce the surface roughness, and the lamp holder of the ultraviolet light repair equipment is adjusted so that the equipment roller moves close to the inner wall of the limiting tube 19, thereby ensuring the stability of its transmission.

[0039] Specifically, in this embodiment, the engineering plastic is polytetrafluoroethylene which has certain flexibility, elasticity and good buffering performance.

[0040] In this embodiment, preferably, Figure 2 , 3 As shown in Figures 4 and 5, a reversing mechanism 8 is provided on the hollow top cover 2, and a guide assembly 7 is provided at the lower end of the limiting cylinder 19. The reversing mechanism 8 is used to drive the hollow top cover 2 to rotate, so as to drive the guide assembly 7 to rotate, and the guide assembly 7 is used to guide the solidified repair material to the horizontal section 102 to be repaired.

[0041] Specifically, in this embodiment, if Figure 4 , 6As shown, the longitudinal section of the hollow top cover 2 is T-shaped, and the straight section at the lower end is inserted into the upper end opening of the vertical section 101, and the outer wall of the straight section is fitted with the inner wall of the vertical section 101 for positioning, and the upper end face is covered on the hollow top cover 2, and the outer diameter of the upper end face is larger than the outer diameter of the vertical section 101, so that an annular gap is provided between the outer side surface of the hollow top cover 2 and the outer wall of the vertical section 101.

[0042] The reversing mechanism 8 includes a rolling wheel 20 and a driving mechanism 13, wherein a plurality of rolling wheels 20 are arranged in a circular array along the axis of the hollow top cover 2 in an annular interval, so that the plurality of rolling wheels 20 are arranged at equal intervals. The outer periphery of the rolling wheel 20 is attached to the outer wall of the vertical section 101, and the driving mechanism 13 is used to drive the rolling wheel 20 to roll along the outer periphery of the vertical section 101 in the annular direction to rotate the hollow top cover 2. The rotation of the hollow top cover 2 drives the limiting cylinder 19 below to rotate, thereby driving the guide assembly 7 at the lower end of the limiting cylinder 19 to rotate.

[0043] Specifically, a rotating shaft 11 is fixedly mounted on the scroll wheel 20, and the upper end of the rotating shaft 11 extends upward and out of the hollow top cover 2. The driving mechanism 13 includes a driving gear 16, an inner gear ring 17 and a driving motor 15, wherein a driving gear 16 is fixedly mounted on the upper end of each rotating shaft 11, and the inner gear ring 17 is rotatably mounted on the upper end of the hollow top cover 2. Each driving gear 16 is distributed inside the inner gear ring 17 and meshes with the internal teeth of the inner gear ring 17 for transmission. A driving motor 15 is mounted on one of the rotating shafts 11, and the driving motor 15 drives the rotating shaft 11 to rotate.

[0044] In this way, when the driving motor 15 drives one of the rotating shafts 11 connected thereto to rotate, the driving gear 16 on the rotating shaft 11 rotates, and then driven by the inner gear ring 17, the remaining driving gears 16 rotate, thereby realizing the synchronous rotation of each rotating shaft 11, realizing the synchronous rotation of each rolling wheel 20, thereby driving the hollow top cover 2, the limiting cylinder 19 and the guide assembly 7 to rotate as a whole, realizing the reversing action of the guide assembly 7. At the same time, by using the external rolling wheel 20, the supporting force of the rolling wheel can be concentrated on the outer surface of the vertical section 101, avoiding the inner tube wall of the vertical section 101 from being damaged by force.

[0045] Of course, in other embodiments, the driving mechanism 13 may also only include the driving motor 15. In this case, a driving motor 15 is provided on each rotating shaft 11. Through the synchronous action of each driving motor 15, each rolling wheel 20 is driven to rotate, thereby realizing reversal.

[0046] In this embodiment, preferably, an inverted L-shaped support top plate 14 is fixedly installed at the position of the hollow top cover 2 corresponding to the driving motor 15, and the upper end of the driving motor 15 is fixedly installed on the lower side of the transverse section of the support top plate 14. It is convenient for the driving motor 15 to cooperate with the corresponding rotating shaft 11 for transmission.

[0047] In this embodiment, preferably, the rolling wheel 20 includes an inner roller 12 and a plurality of rubber pads 18 evenly arranged on the outer surface of the roller 12, and adjacent rubber pads 18 are arranged at equal intervals. The rubber pads 18 can increase friction, ensure that the rolling wheel 20 can roll on the outer wall of the vertical section 101, and reduce damage. The plurality of spaced rubber pads 18 can be used to adapt to the deformation of the rubber and increase the contact area between the rubber pads 18 and the outer wall of the vertical section 101.

[0048] In this embodiment, preferably, Figure 4 , 5 As shown, the guide assembly 7 includes a support frame 9 arranged at the lower end of the limit cylinder 19, and a guide roller 10 rotatably arranged on the support frame 9, wherein the rotation axis 11 of the guide roller 10 extends in the horizontal direction. Specifically, the support frame 9 is U-shaped as a whole and is arranged at the lower end of the support vertical plate 4. In this way, when laying the curing repair material, the guide roller 10 is arranged toward the horizontal section 102 to be repaired by using the reversing mechanism 8. The guide roller 10 can be used to guide the curing repair materials such as cables, base films and hoses to prevent the curing repair materials from bending and winding at the connection between the vertical section 101 and the horizontal section 102.

[0049] The above-mentioned setting utilizes the reversing mechanism 8, which greatly facilitates the operator to flexibly adjust the direction of the guide assembly 7 according to the different directions of the pipeline 1 and the repair requirements, which is not only conducive to the transmission of the ultraviolet light repair equipment, but also convenient for the layout of the bottom film and the hose, reducing the difficulty of operation and time consumption, and improving the construction efficiency. In the process of the bottom film hose entering the pipeline 1, the guide assembly 7 can ensure that the hose moves smoothly and steadily along the predetermined path, avoiding bending, winding, etc., so that it can fit closely to the inner wall of the pipeline 1, creating good conditions for the subsequent laying of repair materials, and further improving the efficiency and quality of the entire pipeline 1 repair work.

[0050] The working process of the present application: When in use, the hollow top cover 2 is buckled on the top of the vertical section 101, the rubber pad 18 of the rolling wheel 20 is pressed against the outer surface of the vertical section 101, and the driving screw 3 is rotated to drive the supporting vertical plate 4 to move downward, and the guide roller 10 of the guide assembly 7 is placed at the bottom. The guide roller 10 is used to guide the cable, bottom film and curing hose in the initial stage.

[0051] Specifically, when laying the bottom film hose, Figure 6 As shown, the guide roller 10 is arranged toward the horizontal section 102, one end of the bottom film hose is fixed on the corresponding laying equipment (such as a reel device), and then introduced into the first limiting cylinder 5 and the second limiting cylinder 6. With the help of the guiding effect of the guide roller 10, the bottom film hose is smoothly laid along the inner wall of the horizontal section 102.

[0052] When the ultraviolet light repair equipment needs to be transported, the guide roller 10 is rotated to the other side away from the horizontal section 102 that needs to be repaired. Specifically, the drive motor 15 is started, and the drive motor 15 drives the rotating shaft 11, the drive gear 16 and the rolling wheel 20 to rotate. The drive gear 16 drives the inner ring 17 to rotate, and the inner ring 17 drives the remaining drive gears 16 and the rotating shaft 11 to rotate synchronously, thereby driving all the rolling wheels 20 to rotate synchronously, thereby driving the hollow top cover 2, the limit cylinder 19 and the guide roller 10 to rotate as a whole.

[0053] Afterwards, one end of the cable is firmly fixed to the ultraviolet light repair equipment, and the other end is accurately connected to the drive shaft of the winch or traction motor. The moving wheels on the ultraviolet light repair equipment are pressed against the inner walls of the first limiting cylinder 5 and the second limiting cylinder 6. While the ultraviolet light repair equipment is lowered, the sliding mechanism drives the limiting cylinder 19 to move downward, and the limiting cylinder 19 always limits and constrains the ultraviolet light repair equipment until the ultraviolet light repair equipment is lowered to the bottom of the horizontal section 102.

[0054] The sliding mechanism is driven in reverse, the limit cylinder 19 moves upward, and the ultraviolet light repair equipment flips horizontally under the action of its own weight and the traction rope. The traction motor is started, the rotation direction and speed of the winch are controlled, and the cable drives the ultraviolet light repair equipment to move forward or backward smoothly in the horizontal section 102 to perform curing and repair operations.

[0055] Example 2: This example provides a different reversing mechanism. Different from Example 1, in this example, when meeting actual usage requirements, the reversing mechanism includes a plurality of equally spaced rotating handles that can be detachably mounted on the hollow top cover. The operator holds the rotating handles to drive the hollow top cover to rotate with the vertical section axis as the axis, thereby realizing the reversal of the guide assembly.

[0056] The above are only preferred embodiments of the present application and are not intended to limit the present application. For those skilled in the art, the present application may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.

[0057] In the description of the embodiments of the present application, it should be noted that if the terms "upper", "lower", "horizontal", "inner", etc. appear, the orientation or position relationship indicated is based on the orientation or position relationship shown in the drawings, or the orientation or position relationship in which the invented product is usually placed when used. It is only for the convenience of describing the present application and simplifying the description, and does not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present application. In addition, the terms "first", "second", etc. are only used to distinguish the description, and cannot be understood as indicating or implying relative importance.

[0058] In addition, if the term "horizontal" appears, it does not mean that the component must be absolutely horizontal, but can be slightly tilted. For example, "horizontal" only means that its direction is more horizontal than "vertical", which does not mean that the structure must be completely horizontal, but can be slightly tilted.
