[0025] Specifically, by rotating the ball cap, the connecting rod moves axially downward under the driving action of the screw rod. The two inclined plates will contract inward under the action of the convex rod to reduce the formed included angle, so that the distance between the two curved plates is reduced to perform a clamping action until the inner walls of the two curved plates are in tight contact with the outer wall of the inner liner pipe joint when the convex rod moves to the bottom end of the first sliding groove, so as to complete the clamping work of the inner liner pipe joint.

[0027] Specifically, the position of the cutting assembly is adjusted by the stud to align the first through hole of the support seat with the fixed seat, so as to ensure that the two inner liner pipe joints can complete the pipe alignment work on the support seat. In addition, under the clamping action of the second clamping mechanism, the stability of the inner liner pipe joint during the processing can be ensured. In addition, the straight rod rotates circularly in the annular groove, so as to drive the scraper to process the thicker inner liner pipe joint, so as to ensure that the thickness of the butt joint of the two inner liner pipe joints can be kept consistent, which is helpful for the subsequent smelting work of the inner liner pipe joint.

Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than an exhaustive list of all embodiments.

[0039] For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0040] The present invention will be further described below with reference to the accompanying drawings.

[0041] Figure 1 Schematically shows the structure of the pipe alignment device 100 for the inner liner pipe joint according to the present invention;

[0042] Figure 2 For Figure 1 is a partial view thereof, which schematically shows the structure of the second clamping mechanism;

[0043] Figure 3 For Figure 1 is a partial view thereof, which schematically shows the structure of the pipe alignment mechanism 20;

[0044] Figure 4 For Figure 1 is a partial view thereof, which schematically shows the structure of the connection mechanism 50;

[0045] Figure 5 For Figure 1 is a partial view thereof, which schematically shows the structure of the cleaning mechanism 60.

[0046] As Figure 1As shown, the pipe alignment device 100 for the inner liner pipe joint according to the present invention includes a support plate 10, a pipe alignment mechanism 20 provided on the support plate 10, and a pair of first clamping mechanisms 30 provided on both sides of the pipe alignment mechanism 20.

[0047] In one embodiment, as Figure 1 and 2 shown, the first clamping mechanism 30 includes a fixed seat 31 configured in the form of a box, a groove plate 32 fixed to the inner wall of the fixed seat 31, and a screw rod 33 extending into the fixed seat 31. Preferably, the outer wall of the groove plate 32 is welded to the inner wall of the fixed seat 31, and the screw rod 33 is threadedly connected to the groove plate 32. Therefore, the screw rod 33 can perform axial movement on the groove plate 32. In other words, the screw rod 33 can perform axial movement while rotating inside the groove plate 32.

[0048] In one embodiment, as Figure 1 shown, first through holes 311 are provided on both sides of the fixed seat 31. Preferably, the two first through holes 311 are symmetrically arranged and can allow the inner liner pipe joint to pass through smoothly, so as to support the inner liner pipe joint, thereby facilitating the subsequent pipe alignment work.

[0049] In the present invention, the inner liner pipe joint is preferably a high-precision HTOP inner liner pipe joint.

[0050] In one embodiment, as Figure 1 shown, a second through hole 312 is provided at the top end of the fixed seat 31. Preferably, the fixed seat 31 forms a clearance fit with the screw rod 33 through the second through hole 312, thereby ensuring the movement path of the screw rod 33. In other words, the position of the screw rod 33 in the radial direction is effectively controlled, so as to ensure that the screw rod 33 can only perform axial movement and rotational movement.

[0051] According to the present invention, a second clamping mechanism is provided inside the fixed seat 31. Preferably, the second clamping mechanism is connected to the end of the screw rod 33. In other words, the screw rod 33 can form an effective connection relationship with the first bearing 43 in the second clamping mechanism, thereby enabling the second clamping mechanism to achieve the purpose of clamping the inner liner pipe joint, and its content will be introduced below.

[0052] In one embodiment, as Figure 2 shown, the second clamping mechanism includes a pair of inclined plates 41 and a connecting rod 42 hinged to the groove plate 32. Among them, a first sliding groove 411 is provided on each inclined plate 41; convex rods 421 are provided at both ends of the connecting rod 42. Preferably, the connecting rod 42 can be matched with the first sliding groove 411 through the convex rods 421, so as to ensure that the connecting rod 42 can form an effective sliding connection with the inclined plate 41.

[0053] In one embodiment, as Figure 2As shown, the second clamping mechanism further includes a first bearing block 43. Preferably, the first bearing block 43 is fixed to the middle of the connecting rod 42, and the bottom end of the screw rod 33 can be hinged to the first bearing block 43 to form a stable link mechanism with the connecting rod 42. Therefore, the connecting rod 42 can perform axial movement within the fixed seat 31 under the driving action of the screw rod 33, and move through the convex rod 421 within the first chute 411, thereby causing the inclined plate 41 to move outward or inward.

[0054] In one embodiment, as Figure 2 shown, the second clamping mechanism further includes a pair of symmetrically arranged curved plates 44. Preferably, the curved plates 44 are fixedly connected to the lower end surface of the inclined plate 41, and each curved plate 44 corresponds to an inclined plate 41. Therefore, by controlling the axial position of the connecting rod 42, the included angle formed by the two inclined plates 41 can be changed, thereby indirectly changing the distance between the two curved plates 44 to further achieve the purpose of clamping or loosening the inner liner pipe joint, the content of which will be introduced below.

[0055] In the present invention, the screw rod 33, the connecting rod 42, the first bearing block 43, the inclined plate 41 and the curved plate 44 are configured as a complete driving mechanism, so that the distance between the two curved plates 44 can be directly controlled by the screw rod 33, so as to cause the curved plates 44 to perform clamping or loosening actions on the inner liner pipe joint, which helps the subsequent work of the inner liner pipe joint on the pipe.

[0056] According to an embodiment of the present invention, the first chute 411 is inclinedly arranged on the inclined plate 41. Therefore, during the axial movement of the connecting rod 42, the included angle formed by the two inclined plates 41 will change, thereby indirectly changing the distance between the two curved plates 44 to further achieve the purpose of clamping or loosening the inner liner pipe joint.

[0057] Preferably, when the connecting rod 42 moves axially downward under the driving action of the screw rod 33, the two inclined plates 41 will contract inward under the action of the convex rod 421 to reduce the formed included angle, so that the distance between the two curved plates 44 is reduced to perform a clamping action. Until the convex rod 421 moves to the bottom end of the first chute 411, the inner walls of the two curved plates 44 are in contact with the outer wall of the inner liner pipe joint, thereby ensuring the stability of the inner liner pipe joint during the processing.

[0058] Preferably, when the connecting rod 42 moves axially upward under the driving action of the screw rod 33, the two inclined plates 41 will expand outward under the action of the convex rod 421 to increase the formed included angle, so that the distance between the two curved plates 44 is increased to perform a loosening action. Until the convex rod 421 moves to the top end of the first chute 411, the inner walls of the two curved plates 44 are completely separated from the outer wall of the inner liner pipe joint, which helps to take out the processed inner liner pipe joint.

[0059] In one embodiment, as Figure 1 and 2 shown, the first clamping mechanism 30 further includes a ball cap 34 fixed to the top end of the screw 33. Preferably, the ball cap 34 is welded to the top end of the screw 33. Therefore, by rotating the ball cap 34, the purpose of rotating the screw 33 can be achieved, thereby improving the use stability and reliability of the screw 33.

[0060] In addition, since the contact area of the ball cap 34 is larger, the holding force can be increased, so that the curved plate 44 can be more easily clamped or released.

[0061] In addition, since the screw 33 is threadedly connected to the groove plate 32. Therefore, the present invention can more precisely and minutely adjust the distance between the two curved plates 44, so that not only can the inner lining pipe joint be stably clamped, but also the problem of damage to the inner lining pipe joint caused by excessive extrusion can be avoided.

[0062] In the present invention, under the combined action of the first through hole 311 on the fixed seat 31 and the second clamping mechanism, it can be ensured that the inner lining pipe joint is always in a stable state during the processing, thereby preventing shaking during processing and further improving the processing stability.

[0063] In one embodiment, as Figure 1 and 3 shown, a first through groove 111 is provided on the support plate 10, and the pipe pair mechanism 20 includes a stud 21 disposed in the first through groove 111 and a cutting assembly adapted to the stud 21. Preferably, the cutting assembly can adjust its axial position on the stud 21 through a sleeve plate 22 (introduced below) to more easily dock with the inner lining pipe joint.

[0064] Preferably, a second bearing seat (not shown) adapted to the stud 21 is provided in the support plate 10. In this way, the stud 21 can rotate infinitely under the action of the second bearing seats on both sides, so as to achieve the purpose of adjusting the height of the cutting assembly.

[0065] In addition, as Figure 1 shown, a vertical rod 211 is welded to the top end of the stud 21. Preferably, the free end of the vertical rod 211 can extend out of the upper end surface of the support plate 10, which helps to drive the stud 21 to rotate.

[0066] In one embodiment, as Figure 1 and 3As shown, the cutting assembly is configured in a U-shaped structure and includes a pair of sleeve plates 22. Preferably, both sleeve plates 22 are sleeved outside the double-headed stud 21, and the sleeve plates 22 form a threaded connection with the double-headed stud 21. Since the position of the double-headed stud 21 does not change, by rotating the double-headed stud 21, the position of the sleeve plate 22 on the double-headed stud 21 can be adjusted to further align the cutting assembly with the fixed seat 31.

[0067] In one embodiment, as Figure 3 shown, the cutting assembly further includes a support seat 23 and a support rod 24 disposed between the support seat 23 and the sleeve plate 22. Preferably, the support rod 24 can firmly connect the support seat 23 and the sleeve plate 22 together, thereby improving the stability of the overall structure of the cutting assembly. Preferably, the support seat 23 is configured in a circular structure, and the inner lining pipe joint can be sleeved outside the support seat 23, thereby completing the pipe work and playing a good supporting role for the inner lining pipe joint to further ensure the smooth progress of the processing operation.

[0068] According to the present invention, as Figure 3 shown, an annular groove 231 is formed in the support seat 23, and the cutting assembly further includes a straight rod 25 disposed in the annular groove 231 and a scraping blade 26 fixed on the straight rod 25. Preferably, the scraping blade 26 can fit with the relatively thick inner lining pipe joint. Therefore, when the straight rod 25 rotates circularly in the annular groove 231, the scraping blade 26 can more easily process the relatively thick inner lining pipe joint.

[0069] During the processing of the present invention, the inner lining pipe joint needs to be sleeved outside the support seat 23, and the straight rod 25 can rotate in the annular groove 231 and drive the scraping blade 26 to perform the processing operation, thereby effectively and stably processing the relatively thick inner lining pipe joint. In this way, the thickness of the butt joint of the two inner lining pipe joints can be kept consistent, which helps the subsequent melting work of the inner lining pipe joint.

[0070] Preferably, during processing, the double-headed stud 21 needs to be adjusted to change the position of the cutting assembly, so as to ensure that the support seat 23 can be aligned with the first through holes 311 on both sides, which helps to improve the butt joint efficiency of the inner lining pipe joint.

[0071] According to the present invention, as Figure 1 、 4 and 5 shown, the pipe butt joint device 100 for the inner lining pipe joint further includes a bottom plate 12 disposed below the support plate 10, a connecting mechanism 50 disposed on the bottom plate 12 and on both sides of the support plate 10, and a cleaning mechanism 60 disposed on the bottom plate 12 and below the support seat 23.

[0072] Preferably, the present invention can be correspondingly connected to an external connection port (not shown) through the connection mechanism 50, thereby ensuring the stability of the pipe alignment device 100 for the inner liner pipe joint during the processing; the present invention can centrally process the waste residues generated during the processing through the cleaning mechanism 60, thereby realizing the centralized temporary storage of the waste residues, preventing dispersion, facilitating cleaning, and facilitating popularization and use.

[0073] In one embodiment, as Figure 4 shown, the connection mechanism 50 includes a square plate 51, a pair of second chutes 52 arranged at intervals and a vertical cylinder 53 provided in the square plate 51. Among them, the second chute 52 is configured as a groove with an elliptical structure, and the vertical cylinder 53 is arranged in the second chute 52, so that it can form a sliding connection with the square plate 51 through the second chute 52. Preferably, the square plate 51 is welded to the bottom plate 12, thereby improving the stability of the pipe alignment device 100 for the inner liner pipe joint during the processing.

[0074] Preferably, in the present invention, there are two square plates 51 in total, and a pair of second chutes 52 arranged at intervals are provided on each square plate 51. In the present invention, the side wall of the vertical cylinder 53 abuts against the inner wall of the second chute 52, so that only the vertical cylinder 53 can perform a sliding and clamping connection in the second chute 52.

[0075] Preferably, as Figure 4 shown, the vertical cylinder 53 in the present invention can be fixedly connected to the external connection port through a bolt 54. Therefore, the present invention can adapt to the actual connection port on site by adjusting the position of the vertical cylinder 53 in the second chute 52, thereby solving the installation conflict, ensuring normal installation and reducing the use difficulty.

[0076] In one embodiment, as Figure 5 shown, the cleaning mechanism 60 includes a receiving plate 61 and a baffle 62 provided on the upper end surface of the receiving plate 61 and configured as a U-shaped structure. Preferably, the waste residues generated during the processing can smoothly fall into the receiving plate 61, which helps with subsequent centralized processing work.

[0077] In one embodiment, as Figure 5 shown, an elliptical second through groove 621 is provided on the baffle 62. And the cleaning mechanism 60 further includes a push plate 63 extending through the second through groove 621 and abutting against the receiving plate 61, and a handle 64 provided at the free end of the push plate 63.

[0078] In the present invention, the cleaning work can be completed by adjusting the position of the push plate 63 in the receiving plate 61 through the handle 64. In other words, the cleaning mechanism 60 can centrally process the waste residues generated during the processing, thereby realizing the centralized temporary storage of the waste residues, preventing dispersion, facilitating cleaning, and facilitating popularization and use.

[0079] The usage process of the present invention is briefly described below:

[0080] First, the bottom plate 12 is attached to the support surface (not shown). The position of the vertical cylinder 53 in the second chute 52 is adjusted to adapt to the actual connection port on-site, and it is fixedly connected to the external connection port through the bolt 54.

[0081] Then, the two inner lining pipe connectors are respectively passed through different fixing seats 31, and the position of the cutting assembly is adjusted through the stud 21 to align the support seat 23 with the first through hole 311 of the fixing seat 31, so as to ensure that the two inner lining pipe connectors complete the pipe alignment work on the support seat 23.

[0082] After that, the ball cap 34 is rotated so that the connecting rod 42 moves axially downward under the driving action of the screw rod 33. When the convex rod 421 moves to the bottom end of the first chute 411, the inner walls of the two curved plates 44 are both in tight contact with the outer wall of the inner lining pipe connector, thereby ensuring the stability of the inner lining pipe connector during the processing.

[0083] Finally, the straight rod 25 rotates circularly in the annular groove 231, thereby driving the scraper 26 to process the thicker inner lining pipe connector, so as to ensure that the thickness at the docking part of the two inner lining pipe connectors can be kept consistent, which is helpful for the subsequent melting work of the inner lining pipe connector.

[0084] Compared with the prior art, the advantages of the present invention are as follows:

[0085] Firstly, the present invention can complete the clamping work of the inner lining pipe connector through the cooperation of the first clamping mechanism 30 and the second clamping mechanism, thereby ensuring the stability of the inner lining pipe connector during the processing.

[0086] Specifically, by rotating the ball cap 34, the connecting rod 42 moves axially downward under the driving action of the screw rod 33. The two inclined plates 41 will contract inward under the action of the convex rod 421 to reduce the formed angle, so that the distance between the two curved plates 44 is reduced to perform the clamping action. When the convex rod 421 moves to the bottom end of the first chute 411, the inner walls of the two curved plates 44 are both in tight contact with the outer wall of the inner lining pipe connector to complete the clamping work of the inner lining pipe connector.

[0087] Secondly, the present invention can complete the pipe alignment work of the inner lining pipe connector through the cooperation of the pipe alignment mechanism 20 and the first clamping mechanism 30, and can also ensure the stability of the inner lining pipe connector during the processing to prevent shaking during processing, thereby ensuring the adjustment ability of the pipe alignment device 100 for the thickness of the inner lining pipe connector.

[0088] Specifically, the position of the cutting assembly is adjusted by the stud 21 so that the support base 23 is aligned with the first through hole 311 of the fixed base 31, thereby ensuring that the two inner liner pipe joints can complete the pipe connection work on the support base 23. In addition, the clamping action of the second clamping mechanism can ensure the stability of the inner liner pipe joint during the processing. Additionally, the straight rod 25 rotates circularly in the annular groove 231, thereby driving the scraper 26 to process the relatively thick inner liner pipe joint, so as to ensure that the thickness at the butt joint of the two inner liner pipe joints can be kept consistent, which is helpful for the subsequent melting work of the inner liner pipe joint.

[0089] Thirdly, the present invention can not only be correspondingly connected with an external connection port (not shown) through the connection mechanism 50, thereby solving the installation conflict problem and ensuring normal installation, and further reducing the use difficulty, so as to further improve the stability of the pipe connection device 100 for the inner liner pipe joint during the processing; but also the waste residues generated during the processing are centrally processed through the cleaning mechanism 60, thereby realizing the centralized temporary storage of the waste residues, preventing dispersion, facilitating cleaning, and facilitating popularization and use.

[0090] The above is only the preferred embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Those skilled in the art can easily make changes or variations within the disclosure scope of the present invention, and such changes or variations should be covered within the protection scope of the present invention. Therefore, the protection scope of the present invention shall be subject to the protection scope of the claims.
