Description

Technical Field

[0002] Galvanized pipe is a kind of corrosion-resistant pipe, which has been widely used in the fields of construction, machinery, etc. However, during the production, transportation and use of galvanized pipe, external forces may cause the surface of galvanized pipe to deform (i.e., produce depressions).

[0003] In the prior art, the depressed part of the galvanized pipe is usually lifted up by a lifting device to reset the depressed part. However, when resetting the depressed part of the galvanized pipe, the lifting device can usually only lift up the depressed part of the galvanized pipe, and the deformation reset effect is poor. Even multiple bumps and depressions may be generated at the original depressed part of the galvanized pipe, which will be more prone to deformation during subsequent use. Utility Model Content

[0057] Embodiment 1

[0058] Figure 1 This is a schematic diagram of the structure of a galvanized pipe deformation reset device of the utility model;

[0059] Figure 2 This is a schematic diagram of the internal structure of a galvanized pipe deformation reset device of the utility model;

[0060] like Figure 1 and Figure 2As shown, a galvanized pipe deformation reset device comprises: a power mechanism 1, a first shell 2 connected to the power mechanism 1, and a lifting mechanism 3 arranged on the first shell 2. It should be noted that in the present utility model, the axial direction refers to the direction of the central axis of rotation of the galvanized pipe, that is, the direction common to the central axis, and the pipe to be reset refers to the galvanized pipe that needs to be deformed and reset.

[0061] In some embodiments, the power mechanism 1 may include a motor 11 and a transmission shaft 12 connected to the motor 11. By connecting one end of the transmission shaft 12 to the output shaft of the motor 11 and the other end to the first housing 2, the first housing 2 is rotated by the transmission shaft 12.

[0062] In some embodiments, the first shell 2 is a concave disc-shaped structure, one end of the transmission shaft 12 is connected to the concave part of the first shell 2, and under the drive of the motor 11, the first shell 2 will rotate with the connection part with the transmission shaft 12 as the axis, and the lifting mechanism 3 is arranged on the outer periphery of the first shell 2. The lifting mechanism 3 follows the rotation of the first shell 2 to make the lifting mechanism 3 abut against the inner wall of the tube to be reset, and the recessed part of the tube to be reset is lifted by the lifting mechanism 3, so as to reset the recessed part of the tube to be reset. The specific reset process will be further described below.

[0063] In some embodiments, a rescue hook 22 is further provided on a side of the first housing 2 away from the transmission shaft 12 so as to facilitate the rescue of the galvanized pipe deformation reset device located in the pipe to be reset when a failure occurs.

[0064] Figure 3 This is a partial structural schematic diagram of a galvanized pipe deformation reset device of the utility model;

[0065] Figure 4 This is a structural schematic diagram of a jacking mechanism in a galvanized pipe deformation reset device of the utility model;

[0066] Furthermore, if Figure 3 and Figure 4As shown, the lifting mechanism 3 includes: a first main arm 31, and a first roller 32 arranged on the first main arm 31; wherein, the first main arm 31 is arranged to be inclined to the axis of the tube to be reset, and one end of the first main arm 31 is connected to the first shell 2. When the motor 11 drives the first shell 2 to rotate, the first roller 32 will follow the rotation of the first main arm 31 and move on the inner wall of the tube to be reset. The first roller 32 abuts against the inner wall of the tube to be reset, so as to utilize the movement of the first roller 32 to lift the recessed part of the tube to be reset and realize the reset process of the tube to be reset; on the other hand, by setting the first main arm 31 to be inclined to the axis of the tube to be reset, when the first roller 32 moves on the inner wall of the tube to be reset, it will provide a traction force for the galvanized pipe deformation reset device to move along the axial direction of the tube to be reset, thereby pulling the galvanized pipe deformation reset device to move along the axial direction of the tube to be reset.

[0068] Figure 6 This is a cross-sectional view of a galvanized pipe deformation reset device of the utility model;

[0069] Figure 7 This is a schematic diagram of part of the internal structure of a galvanized pipe deformation reset device of the utility model;

[0070] Figure 8 This is a partial cross-sectional view of a galvanized pipe deformation reset device of the utility model;

[0071] like Figure 4 , Figure 5 , Figure 6 , Figure 7 and Figure 8 As shown, the galvanized pipe deformation reset device also includes: a first pushing mechanism 4, which is connected to the lifting mechanism 3 and is used to adjust the inclination angle between the first main arm 31 and the axial direction of the pipe to be reset, thereby adjusting the contact angle between the first roller 32 and the inner wall of the pipe to be reset.

[0072] Specifically, the first pushing mechanism 4 includes a second shell 41, a first pushing member 42 provided on the second shell 41, and a bridging assembly 43 connected to the first pushing member 42; further, the lifting mechanism 3 also includes: a first fixed seat 33, and an adjusting arm 34 connected to the first fixed seat 33, wherein the adjusting arm 34 is connected to the bridging assembly 43, and the first fixed seat 33 is connected to an end of the first main arm 31 away from the first roller 32.

[0073] Furthermore, the bridging assembly 43 includes: a bridge ring 431, a connecting seat 432 connected to the bridge ring 431, and a connecting fin 433 connected to the connecting seat 432. The first shell 2 is also provided with a first slide groove 21 adapted to the connecting fin 433.

[0074] In some embodiments, the connecting fin 433 is slidably connected to the first slide groove 21. When the first housing 2 rotates, the connecting fin 433 can be driven to rotate through the first slide groove 21, thereby driving the connecting seat 432 connected to the connecting fin 433 to rotate. Furthermore, the connecting seat 432 is connected to the bridge ring 431 via a bearing, so that the connecting seat 432 can rotate in the bridge ring 431. At the same time, when the bridge ring 431 moves along the axial direction of the tube to be reset, the connecting seat 432 can be driven to move synchronously along the axial direction.

[0075] In some embodiments, the first pushing member 42 is used to push the end of the adjusting arm 34 connected to the bridging assembly 43 to move along the axial direction of the tube to be reset by pushing the bridging assembly 43. An exemplary first pushing member 42 can be an electric push rod. When the electric push rod is extended, it will push the connecting seat 432 and the connecting fin 433 to slide in the first slide groove 21 through the bridge ring 431, thereby realizing the displacement process of the connecting seat 432.

[0076] Furthermore, one end of the first main arm 31 away from the first roller 32 is connected to the first fixed seat 33, one end of the first fixed seat 33 is hinged to the second shell 41, and the other end is hinged to the adjusting arm 34, and one end of the adjusting arm 34 away from the first fixed seat 33 is hinged to the connecting seat 432. By hingedly connecting the two ends of the adjusting arm 34 to the connecting seat 432 and the first fixed seat 33 respectively, when the connecting seat 432 moves along the axial direction of the tube to be reset, the first fixed seat 33 will rotate around the hinge with the first shell 2 as the axis, thereby adjusting the angle between the first fixed seat 33 and the axial direction of the tube to be reset, and then adjusting the angle between the first roller 32 and the axial direction of the tube to be reset.

[0077] Furthermore, by adjusting the angle between the first roller 32 and the axial direction of the tube to be reset, the running speed of the galvanized pipe deformation reset device in the tube to be reset can be adjusted. Specifically, when the angle between the first roller 32 and the axial direction of the tube to be reset is closer to vertical, the first roller 32 rotates with the second shell 41, and the running speed of the galvanized pipe deformation reset device in the tube to be reset is slower. When resetting the recess of the galvanized pipe, the axial movement of the galvanized pipe deformation reset device in the tube to be reset is reduced, and the first roller 32 is used to squeeze the recess multiple times to achieve the reset process. At the same time, the multiple squeezing of the first roller 32 can also effectively improve the reset effect. Of course, when the galvanized pipe deformation reset device moves to the reset position in the tube to be reset, the running speed of the galvanized pipe deformation reset device in the tube to be reset can be increased by reducing the angle between the first roller 32 and the axial direction, so that the galvanized pipe deformation reset device can move quickly to the reset position.

[0078] In some embodiments, an infrared heater 434 is further provided on the bridge ring 431. The infrared heater 434 heats the recess of the tube to be reset by radiating heat, so that the recess is more easily lifted by the lifting mechanism 3 to improve the reset effect.

[0079] In some embodiments, the galvanized pipe deformation reset device also includes: a second pushing mechanism 5, which is connected to the lifting mechanism 3 and is used to adjust the distance between the abutment point between the lifting mechanism 3 and the pipe to be reset and the center axis of the pipe to be reset. By adjusting the distance between the abutment point between the lifting mechanism 3 and the pipe to be reset and the center axis of the pipe to be reset, the lifting mechanism 3 is fully in contact with the inner wall of the pipe to be reset to enhance the deformation reset effect of the pipe to be reset. The specific adjustment process will be further described below.

[0080] Furthermore, the first fixed seat 33 includes: a fixed frame 331, a second slide groove 332 provided in the fixed frame 331, and a first sliding member 333 slidably connected to the second slide groove 332; the jacking mechanism 3 also includes: a sub-stage hydraulic rod 35, and a first support arm 36; wherein, the sub-stage hydraulic rod 35 is fixed in the fixed frame 331, the output end of the sub-stage hydraulic rod 35 is connected to the first sliding member 333, one end of the first support arm 36 is hinged to the first main arm 31, and the other end is hinged to the fixed frame 331.

[0081] In some embodiments, when the sub-stage hydraulic rod 35 is working, the extension and retraction of the sub-stage hydraulic rod 35 will push the first sliding member 333 to slide in the second sliding groove 332, thereby transmitting the first main arm 31 to move away from one end of the first roller 32, and by adjusting the angle between the first main arm 31 and the first fixed seat 33, the distance between the first roller 32 and the first fixed seat 33 is adjusted, thereby adjusting the distance between the abutment between the lifting mechanism 3 and the tube to be reset and the center axis of the tube to be reset.

[0082] In some embodiments, the second pushing mechanism 5 includes: a mother hydraulic rod 51, a push cylinder 52 connected to the mother hydraulic rod 51, a rotating member 53 connected to the push cylinder 52, a hydraulic bin 54 connected to the rotating member 53, and a piston 55 provided in the hydraulic bin 54; in some embodiments, the mother hydraulic rod 51 can be connected to the motor 11 via a mounting frame, and the mother hydraulic rod 51 is used to drive the push cylinder 52 to move along the axial direction of the tube to be reset. In some embodiments, the push cylinder 52 is a hollow cylindrical structure, and its inner wall is connected to the rotating member 53 via a bearing.

[0083] Furthermore, one end of the rotating member 53 is a hollow disc-shaped structure, and the other end is a cylindrical structure, wherein the end of the rotating member 53 that is a cylindrical structure is socketed with the transmission shaft 12 and is connected to the push cylinder 52 via a bearing, and the end of the rotating member 53 that is a hollow disc is connected to the inner wall of the hydraulic chamber 54. In some embodiments, the hydraulic chamber 54 is a hollow cylindrical structure filled with hydraulic medium, one end of the hydraulic chamber 54 is connected to the first shell 2, and the piston 55 is disposed in the hydraulic chamber 54. The enclosed space between the piston 55 and the first shell 2 in the hydraulic chamber 54 is a hydraulic chamber 56. Furthermore, a limit spring 57 is provided between the end of the rotating member 53 that is a hollow disc-shaped structure and the piston 55.

[0084] In some embodiments, when the mother hydraulic rod 51 is not working, the push cylinder 52 cannot rotate, and the hydraulic chamber 54 will rotate along with the first shell 2. When the mother hydraulic rod 51 is working, it pushes the push cylinder 52 to move axially along the tube to be reset, thereby pushing the rotating member 53 to move axially along the tube to be reset, and then pushing the piston 55 to move axially along the tube to be reset in the hydraulic chamber 54 through the limit spring 57 to adjust the hydraulic pressure in the hydraulic chamber 56.

[0085] In some embodiments, the second jacking mechanism 5 further includes a connecting pipe 58 connecting the hydraulic chamber 56 with the sub-stage hydraulic rod 35, and a first distance sensor 59 provided on the first fixed seat 33, wherein the length of the sub-stage hydraulic rod 35 is adjusted by adjusting the hydraulic pressure in the hydraulic chamber 56, thereby pushing the output end of the sub-stage hydraulic rod 35 connected to the first arm 36 to be extended and retracted, thereby adjusting the angle between the first main arm 31 and the first fixed seat 33; the first distance sensor 59 is used to determine the distance between the abutment point of the jacking mechanism 3 and the pipe to be reset and the central axis of the pipe to be reset by obtaining the distance between the sub-stage hydraulic rod 35 and the first distance sensor 59, so as to adjust the extension length of the sub-stage hydraulic rod 35 through the mother hydraulic rod 51. Of course, the galvanized pipe deformation reset device is also provided with a hydraulic pump station connected to the mother hydraulic rod 51, which is used to adjust the extension length of the mother hydraulic rod 51.

[0086] like Figure 4 and Figure 5 As shown, in some embodiments, the galvanized pipe deformation reset device further includes: a third shell 6, and a deformation detection mechanism 7 arranged on the third shell 6, and the deformation detection mechanism 7 is used to detect the reset degree of the pipe to be reset after reset, and the specific detection process will be further described below.

[0087] Fig. 9 This is a structural schematic diagram of a deformation detection mechanism in a galvanized pipe deformation resetting device of the utility model;

[0088] like Figure 5 and Fig. 9 As shown, in some embodiments, the deformation detection mechanism 7 includes: a second fixed seat 71, a second main arm 72 hinged to the second fixed seat 71, a second roller 73 arranged on the second main arm 72, a second support arm 74 connecting the second main arm 72 with the second fixed seat 71, a second sliding member 75 connected to the second support arm 74 and slidably connected to the second fixed seat 71, and a second distance sensor 76 adapted to the second sliding member 75, wherein the second fixed seat 71 is connected to the third shell 6, so that the deformation detection mechanism 7 is fixed to the outside of the galvanized pipe deformation reset device.

[0089] In some embodiments, the deformation detection mechanism 7 is arranged along the axial direction of the tube to be reset. By setting the deformation detection mechanism 7 along the axial direction of the tube to be reset, on the one hand, the jacking mechanism 3 is assisted to make the galvanized pipe deformation reset device move in the tube to be reset, and on the other hand, the degree of depression of the galvanized pipe after reset can also be detected.

[0090] Furthermore, one end of the second support arm 74 is connected to the second main arm 72, and the other end is hinged to the second sliding member 75. When the galvanized pipe deformation reset device moves in the pipe to be reset, the second roller 73 will abut against the inner wall of the reset galvanized pipe. If there is still a depression on the inner wall of the reset galvanized pipe, the second main arm 72 will rotate on the second fixed seat 71 with the hinge as the axis through the second roller 73 abutting against the inner wall of the galvanized pipe, thereby causing the second sliding member 75 to slide in the second fixed seat 71.

[0091] Furthermore, the second distance sensor 76 determines the concavity of the inner wall of the galvanized pipe by acquiring the distance between the second sliding member 75 and the second distance sensor 76, so as to detect the degree of deformation reset of the galvanized pipe. In some more preferred embodiments, the second sliding member 75 is also connected to the second fixing seat 71 through a support spring, and the direction in which the support spring is arranged is parallel to the direction in which the second sliding member 75 moves. On the one hand, the second sliding member 75 is limited, and on the other hand, the movement of the second sliding member 75 can be made smoother.

[0092] In some feasible implementations, a load-bearing pulley device may be further provided at the bottom of the third shell 6 to reduce the influence of the galvanized pipe deformation reset device's own gravity when resetting the recessed portion of the pipe to be reset.

[0093] The galvanized pipe deformation resetting device provided by the utility model is used for resetting, and the steps include:

[0094] (a) Rapid positioning;

[0095] The first housing 2 is driven to rotate by the power mechanism 1, and the first roller 32 of the lifting mechanism 3 abuts against the inner wall of the pipe to be reset, and the galvanized pipe deformation reset device is driven to move to the reset position in the pipe to be reset. In this step, the angle between the first roller 32 and the axis of the pipe to be reset is the first angle;

[0096] (b) Adjust reset parameters;

[0097] The first pushing mechanism 4 drives the adjusting arm 34 to move axially at one end hinged with the first pushing mechanism 4, and the first main arm 31 rotates through the first fixing seat 33. In this step, the angle between the first roller 32 and the axis of the pipe to be reset is the second angle, wherein the second angle is greater than the first angle.

[0098] The second push mechanism 5 drives the piston 55 to move in the hydraulic chamber 54, thereby increasing the hydraulic pressure in the hydraulic chamber 56, and extending the sub-stage hydraulic rod 35 through the connecting pipe 58, so that the first roller 32 is fully in contact with the inner wall of the tube to be reset;

[0099] The first housing 2 is driven to rotate by the power mechanism 1, and the first roller 32 of the lifting mechanism 3 abuts against the inner wall of the tube to be reset to lift the concave portion of the tube to be reset.

[0100] Finally, it should be noted that the embodiments of the present invention disclose only preferred embodiments of the present invention, which are only used to illustrate the technical solutions of the present invention, rather than to limit them. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that the technical solutions described in the aforementioned embodiments may still be modified, or some of the technical features may be replaced by equivalents. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the various embodiments of the present invention.
