Description

Technical Field

[0001] The utility model relates to the technical field of pipeline repair, in particular to a lining hose cutting device for light-curing repair. Background Art

[0002] The light-curing repair lining hose is a hose used in trenchless pipeline repair. It is used to repair or update damaged, aged or leaking underground pipelines. The use process includes designing and manufacturing the corresponding lining hose, and then pushing the lining pipe into the pipeline to be repaired by air pressure and clinging to the inner wall of the old pipeline. After that, ultraviolet light is used to cure the lining hose, and finally a high-strength new pipeline is formed.

[0003] In order to ensure that the repaired pipeline can be effectively connected with the surrounding pipelines, it is usually necessary to cut both ends of the hose after it is solidified. The existing method is mostly for construction workers to cut the outer wall of the lining hose with handheld cutting equipment. This method is not only inefficient but also easily causes uneven cutting surfaces. In addition, because the pipeline is located underground, it is necessary to cut through a working well. In some special environments, the construction workers have limited operating space due to the small space of the working well, which increases the difficulty of cutting operations.

[0004] At the same time, in order to improve the stability of the connection between the hose and the surrounding pipeline system, it is usually necessary to grind the end face of the hose after cutting to remove burrs or rough surfaces that may be generated. However, some cutting devices currently cannot provide the end face grinding function, so construction workers are required to carry additional grinding equipment to complete this process, which not only reduces construction efficiency, but also increases the complexity and labor burden of operation.

DETAILED DESCRIPTION

[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] See also Figure 1-6As shown, a lining hose cutting device for light-curing repair includes a mounting column 1, one end of which is provided with an inner support mechanism 2. The inner support mechanism 2 at one end of the mounting column 1 is extended into the inner cavity of the hose to be cut, so that the inner wall of the hose after curing can be stably supported, so that the mounting column 1 can be automatically located at the center of the hose to ensure the accuracy and consistency of the hose cutting operation. An annular groove 5 is fixedly connected to the middle of the surface of the mounting column 1, and a support frame 4 is slidably connected to the inner wall of the annular groove 5. The support frame 4 includes a slip ring and a plurality of pillars. The slip ring is slidably connected to the inner wall of the annular groove 5, and the pillars are fixedly connected to one side of the slip ring and are evenly distributed. One end of the pillar of the support frame 4 is fixedly connected to an inner tooth Ring plate 3, the inner wall of the inner gear ring plate 3 is fixedly connected with uniformly distributed teeth, the top of the mounting column 1 is fixedly connected with a driving motor 11, the output shaft of the driving motor 11 is fixedly connected with a driving gear 12, the position and specification of the teeth of the driving gear 12 and the inner gear ring plate 3 are matched, and they are meshed with each other. When the driving motor 11 provides power to drive the driving gear 12 to mesh and rotate with the teeth of the inner gear ring plate 3, the inner gear ring plate 3 can be rotated with the mounting column 1 as the center, and at this time, the sliding connection between the support frame 4 and the annular groove 5 can provide stable support and limiting effect for the rotation of the inner gear ring plate 3, and the bottom of the mounting column 1 is fixedly connected with a support block 10, and one side of the support block 10 is fixed The fixedly connected connecting rod is rotatably connected with a driven gear 9, and the specifications of the driven gear 9 and the driving gear 12 match each other. The teeth of the driven gear 9 and the inner gear ring plate 3 mesh with each other, and can provide a meshing effect for the bottom of the inner wall of the inner gear ring plate 3 when it rotates, so as to reduce the vibration during its rotation, thereby improving the stability and smoothness of the rotation of the inner gear ring plate 3, and then ensuring that it maintains a stable rotation trajectory, further improving the cutting efficiency and accuracy of the device, and a cutting mechanism 6 is installed on one side of the inner gear ring plate 3. When the inner gear ring plate 3 rotates, it can drive the cutting mechanism 6 to rotate synchronously, thereby enabling the device to cut the excess hose in the inner cavity of the hose after curing, which can effectively solve the problem of excessive hose cutting. In order to solve the situation that the operating space in the construction environment is small and it is not conducive to cutting the outer surface of the hose, a grinding mechanism 7 is provided on the surface of the inner gear ring plate 3 and on one side of the cutting mechanism 6. The grinding mechanism 7 is used in conjunction with the cutting mechanism 6 to grind the end face of the hose after cutting to make the end face of the hose smooth, thereby improving the stability and reliability of the pipeline connection. An auxiliary mechanism 8 is provided at the other end of the mounting column 1. The auxiliary mechanism 8 can enable the staff to intuitively display the length of the mounting column 1 extending into the hose, thereby controlling and mastering the effective cutting length of the hose, thereby reducing the situation where errors and inaccuracies occur in the hose cutting distance, and improving the consistency and efficiency of the cutting work.

[0023] The inner support mechanism 2 includes a hydraulic push rod 21, which is installed at one end of the mounting column 1. The output end of the hydraulic push rod 21 is hinged with a plurality of support rods 22 through a support, and the other end of the support rod 22 is fixedly connected with a contact plate 23 through a hinged support. The material of the contact plate 23 is a rubber material with large friction and elasticity. The surface of the contact plate 23 is provided with anti-slip patterns, which can produce a certain elastic deformation when in contact with the inner wall of the hose to increase the friction between them. One side of the bottom of the contact plate 23 is hinged with a support rod 24 through a fixed support, and the other end of the support rod 24 is fixedly connected to the surface of the mounting column 1 through a hinged support. When the output end of the hydraulic push rod 21 is extended or retracted, multiple support rods 22 can be driven to move synchronously. Under the connection between the contact plate 23 and the support rod 24, the inclination angle of the contact plate 23 can be changed, so that one side of the bottom of the contact plate 23 can be supported or lowered. At this time, the contact plate 23 can change the inclination angle of the support rod 24. There are two support rods 24 and they are distributed in parallel. Under the limiting effect of the synchronous tilting movement of the two support rods 24, the contact plate 23 can maintain a relatively stable lifting and lowering movement. Under the synchronous rising effect of several contact plates 23, the inner wall of the hose can be contacted and supported, so that the mounting column 1 can be automatically located at the center of the hose. By controlling the length of the output end of the hydraulic push rod 21, the inner wall of the hose with different diameters can be stably supported, which can improve the flexibility and adaptability of the device.

[0024] The cutting mechanism 6 includes a first slide groove 61, which is located on the surface of the inner gear ring plate 3. The first slide groove 61 is designed to be inclined at an angle. The cross-sectional shape of the first slide groove 61 is T-shaped. A first slider 62 is slidably connected to the inner wall of the first slide groove 61. The first slider 62 matches the shape of the first slide groove 61, so that the first slider 62 can slide and move smoothly in the inner cavity of the first slide groove 61 without detachment. One side of the first slider 62 extends to one side of the inner gear ring plate 3 through the first slide groove 61. A cutting wheel 63 is installed on one side of the first slide groove 61 through a rotating shaft. A power component 64 is provided on one side of the cutting wheel 63. The power component 64 includes a mounting shell and a motor installed inside. The output shaft of the power component 64 motor passes through the outside of the mounting shell and is fixedly connected to the rotating shaft of the cutting wheel 63, so as to drive the cutting wheel 63 to rotate. 3 rotates, at this time, the power component 64 drives the cutting wheel 63 to rotate, and the inner wall of the hose can be cut. One side of the inner gear ring plate 3 is fixedly connected with an electric push rod 65 through a support, and the output end of the electric push rod 65 is fixedly connected to one side of the first slider 62. When the electric push rod 65 is extended and retracted, the first slider 62 can slide and move in the first slide groove 61, so that the cutting wheel 63 can move on one side of the inner gear ring plate 3, thereby enabling the cutting wheel 63 to perform a stable ring cutting operation on the inner wall of the hose. By controlling the length of the electric push rod 65, hoses with different diameters and different wall thicknesses can be cut, and the inner wall of the hose can be supported by the internal support mechanism 2, so that the positions of the cutting wheel 63 and the hose can be kept relatively stable during the cutting process, which can ensure the accuracy and consistency of the hose cutting. The first slider 62 and the power component 64 are both used in conjunction with the grinding mechanism 7.

[0025] The grinding mechanism 7 includes a second slide groove 71, which is located on the surface of the inner gear ring plate 3 and on one side of the first slide groove 61. The cross-sectional shape of the second slide groove 71 is T-shaped. The second slide groove 71 is parallel to the first slide groove 61. The inner wall of the second slide groove 71 is slidably connected with a second slider 72. The second slider 72 matches the shape of the second slide groove 71. One side of the second slider 72 extends to one side of the inner gear ring plate 3 through the second slide groove 71. A grinding wheel 73 is installed on one side of the second slider 72 through a rotating shaft. A synchronous wheel assembly 75 is provided at one end of the rotating shaft of the grinding wheel 73. The synchronous wheel assembly 75 is used in conjunction with the power component 64. The synchronous wheel assembly 75 includes two gears and a transmission rack belt. The two gears are fixedly connected to the rotating shaft of the grinding wheel 73 and the output shaft of the motor of the power component 64, respectively, and the transmission rack belt is meshed with the surfaces of the two gears. When the power component 64 provides power, the grinding wheel 73 can be driven by the transmission of the synchronous wheel assembly 75. The second slider 72 is rotated to grind the end face of the hose. The position of the second slider 72 in the vertical direction is offset compared to the position of the first slider 62. A connecting plate 74 is fixedly connected between the first slider 62 and the second slider 72. After the cutting mechanism 6 completes the ring cutting of the hose, the output end of the electric push rod 65 continues to extend, so that the first slider 62 drives the cutting wheel 63 to move to the outside of the hose. At this time, the second slider 72 can be driven by the rigid connection of the connecting plate 74 to slide in the inner cavity of the second slide groove 71 toward the hose wall, so that the grinding wheel 73 can contact the end face of the hose after cutting. Under the cooperation of the power component 64 and the synchronous wheel assembly 75, the rotating grinding wheel 73 can grind the burrs on the end face of the hose, so that the end face of the hose becomes relatively flat and smooth. The smooth surface can provide a larger contact area and a tighter connection, thereby improving the stability and reliability of the subsequent pipeline connection and reducing the risk of leakage.

[0026] The auxiliary mechanism 8 includes a receiving groove 81, which is located on one side of the top of the mounting column 1. The cross-sectional shape of the receiving groove 81 is T-shaped. A baffle 82 is slidably connected to the upper part of the inner cavity of the receiving groove 81. A cylinder 83 is fixedly connected to the bottom of the baffle 82. The cylinder 83 is adapted to the bottom shape of the inner cavity of the receiving groove 81 and is slidably connected. By lifting one end of the baffle 82 through the receiving groove 81, the cylinder 83 can rotate at the bottom of the inner cavity of the receiving groove 81, and at this time, the baffle 82 can move along the inner wall of the receiving groove 81. The mounting post 1 is slidably moved, and a scale line 84 is provided on the surface of the mounting post 1 and on one side of the receiving groove 81. The retaining bar 82 is fitted with one side of the hose to be cut. With reference to the retaining bar 82 and the scale line 84, the distance that the mounting post 1 extends into the hose can be intuitively displayed, so that the cutting wheel 63 can be in the position where cutting is required, thereby improving the accuracy of the length of the cut hose. After use, the retaining bar 82 is rotated to make it fit into the receiving groove 81, so as to achieve the effect of storing and hiding it.

[0027] It is worth noting that the power component 64 proposed in this technical solution is a prior art, and its working principle and beneficial effects when used are not described in detail here.

[0028] Working principle: When cutting the cured hose, first extend the inner support mechanism 2 at one end of the mounting column 1 into the hose, then lift the stop bar 82 to make it fit with one end of the hose. With the cooperation of the stop bar 82 and the scale line 84, the mounting column 1 can be moved accordingly according to the distance of the hose to be cut, so that the cutting wheel 63 can be in the correct position. Next, start the hydraulic push rod 21 to extend its output end to drive the multiple support rods 22 to move. With the cooperation of the contact plate 23 and the support rod 24, the contact plate 23 can be raised, so that the inner wall of the hose can be supported. Then start the drive motor 11 to make the driving gear 12 drive the inner gear ring plate 3 to rotate, and then start the electric push rod 65 and the power unit. Component 64, the output end of the electric push rod 65 drives the first slider 62 to slide in the first slide groove 61, and the moving first slider 62 can drive the cutting wheel 63 in a rotating state to perform annular cutting on the inner wall of the hose, thereby achieving the purpose of cutting the hose. When grinding the end face of the cut hose, the output end of the electric push rod 65 is continued to be extended, so that the first slider 62 drives the cutting wheel 63 to move out of the outside of the hose. At this time, the second slider 72 can be driven by the connecting plate 74 to move in the second slide groove 71 until the grinding wheel 73 contacts the end face of the hose. Under the transmission action of the synchronous wheel assembly 75, the rotating grinding wheel 73 grinds the end face of the hose, and the burrs on the end face of the hose can be removed and made smooth.
