Description

Technical Field

[0001] The invention relates to the technical field of repairing a lock pier wall facing steel plate, and in particular to a method for repairing a torn lock pier wall facing steel plate. Background Art

[0002] As water transportation on the Grand Canal continues to grow, the locks operate 24 / 7. The vessels plying the canal are all steel vessels. Due to their large tonnage, these vessels often rub against the mooring piers during transit and docking, and against the navigation piers when entering and exiting the locks. The piers are typically reinforced concrete. To ensure their longevity, a steel armor plate is fixed to the concrete's exterior, corresponding to the height of the ship's sidewalls. Because a vessel's hull is partially above and partially below the water's surface, coupled with the ebb and flow of tides, the top edge of the armor plate is positioned at a certain height above the water's surface at high tide, and the bottom edge is positioned at a certain depth below the water's surface at low tide. However, over time, as the ship's hull and the armor plate contact and rub against each other repeatedly, they can warp, bend, or even tear, posing a safety hazard to the vessel. It has become an inevitable requirement to complete some minor faults that affect the normal operation of the lock in the shortest possible time. Therefore, the emergency maintenance work of the lock came into being.

[0003] In the absence of mature technology, such damaged armor plates could only be cut off first to alleviate the immediate safety hazard. The shape and structure of the repair plate would then be determined by rubbing the steel plate cut underwater. However, since the cutting process was not directly along the line between the damaged area and the area still in contact with the pier wall concrete, and it was impossible to determine whether the smooth surface of the armor plate would be completely in contact with the concrete before cutting, after cutting the warped or torn area of ​​the armor plate, the edge of the damaged area still needed to be trimmed or cut to ensure that the edge of the damaged area was completely in contact with the concrete. This ensured that the armor plate after welding the repair plate to the damaged area would also be in contact with the concrete. Moreover, each cut would cause the cut area of ​​the armor plate to deform due to heat, resulting in the shape of the cut armor plate not matching the actual shape of the damaged area even after splicing. This made it impossible to obtain a repair plate that matched the damaged area from the cut armor plate. Furthermore, since the hull floats on the surface of the water, the most frequent contact point between the pier wall's armor plate and the hull is also at the water's surface. This results in the armor plate's damage often being partially above the surface and partially below. Since the water quality is often not clear, even divers cannot accurately observe the damaged area below the surface. Furthermore, the divers' floating position in the water causes them to sway due to the waves, making it difficult to stabilize the template and apply force. In particular, when the armor plate is torn, the damaged area, while not large in total compared to the overall armor plate, is complex in shape and has a wide tear, making it even more difficult to perform rubbing. All of these factors negatively impact rubbing the damaged area of ​​the armor plate through the pier wall surface. Therefore, it is currently impossible to obtain the repair plate structure by directly rubbing the damaged area of ​​the armor plate.

[0004] However, with the constant flow of ships on the water, and since locks are essential ports of passage, any repairs must be short and occupy a small area of ​​the water to minimize disruption to passing vessels. Furthermore, structures such as navigation piers and mooring piers, located in the waterway, cannot be repaired underwater, even during major repairs. Consequently, damaged pier armor plates cannot be repaired promptly, requiring them to be replaced only when they are damaged beyond repair and included in the lock overhaul. Consequently, the need for rapid and accurate underwater sizing of steel plates to be welded has become urgent, making accurate underwater sizing of steel plates a routine emergency response. Summary of the Invention

[0005] The purpose of the present invention is to overcome the shortcomings of the existing technology and provide a method for repairing torn steel plates of the pier wall armor. Even if the bottom edge of the damaged part cannot be seen clearly because it is underwater, the shape of the bottom edge of the damaged part can be traced to facilitate obtaining a repair steel plate that accurately matches the damaged part. When the damaged pier wall armor plate is repaired, the repair steel plate that matches the damaged part can be accurately cut out and repaired, thereby improving the repair efficiency and repair quality of the armor steel plate.

[0006] The technical solution adopted by the present invention is:

[0007] The method for repairing a torn steel plate of a lock pier wall comprises the following steps:

[0008] 1) Cut away the damaged parts of the pier wall's facing steel plate where warping, bulging, and tearing occur, so that the concrete corresponding to the damaged parts of the facing steel plate is exposed;

[0009] 2) The edges of the damaged part are trimmed by hammering, bending or cutting to make the edges of the damaged part fit the concrete at the corresponding position;

[0010] 3) Through the cooperation of divers and shore personnel, fix the guide rail installation strips to the pier walls on the outside of the maximum size position on both sides of the damaged part of the armor plate;

[0011] 4) Fix the guide rail along the guide rail installation strips, and make sure that the bottom end of the guide rail is lower than the maximum dimension of the bottom of the damaged part, and the top end of the guide rail is flush with or higher than the top surface of the pier wall;

[0012] 5) Move the horizontal bottom rod, which is movably connected to the guide rail at both ends, downward along the guide rail until the top surface is lower than the maximum bottom dimension position of the damaged area, and then connect and fix it to the guide rail;

[0013] 6) The positioning guide rods A, which are provided with positioning guide grooves parallel to the guide rails, are removably fixed to the back side of the guide rails, and the positioning guide heads at both ends of the bottom of the horizontal bottom rod are located at the bottom ends of the positioning guide grooves. The range of motion of the positioning guide heads in the positioning guide grooves is equal to the length of the slot plate.

[0014] 7) Removably fix the trough plate containing the rubbing pad to be printed to the rubbing push plate of the horizontal adjustment frame in the lifting adjustment frame, and make the rubbing pad face the damaged surface steel plate;

[0015] 8) Then move the lateral adjustment frame horizontally to the maximum travel position on one side of the lifting adjustment frame, and then use the positioning guide rod B to limit the horizontal position. Then move the lifting adjustment frame downward along the guide rail until it contacts the top surface of the horizontal bottom rod;

[0016] 9) The hydraulic cylinder A fixed on the transverse adjustment frame drives the rubbing push plate and the trough plate filled with rubbing pad to move toward the facing steel plate until the end surface of the rubbing pad is in pressure contact with the concrete corresponding to the damaged part of the facing steel plate, and maintains the pressure for a period of time;

[0017] 10) After the rubbing pad is finished, the hydraulic cylinder A drives the rubbing push plate and the groove plate with the rubbing pad to return to the starting position, and then the lifting adjustment frame is moved upward along the track (9) to the top of the pier wall, and the groove plate with the rubbing pad that has been finished is separated from the rubbing push plate, and the groove plate with the rubbing pad to be rubbing is detachably fixed to the rubbing push plate, and the rubbing pad is placed facing the damaged protective steel plate;

[0018] 11) Then, use positioning guide rod B to move the transverse adjustment frame toward the other end of the lifting adjustment frame until it is adjacent to the previous position of the transverse adjustment frame, so that the edge of the rubbing pad facing the starting end of the transverse adjustment frame is aligned with the edge of the previous rubbing pad facing away from the starting end of the transverse adjustment frame.

[0019] 12) Repeat steps 8) to 11) until the rubbing pad is finished after the horizontal adjustment frame moves to the other end of the lifting adjustment frame through the positioning guide rod B. At this time, repeat step 10);

[0020] 13) Loosen the two ends of the horizontal bottom bar from the guide rail, and move the positioning guide heads at both ends of the horizontal bottom bar upward along the positioning guide groove to the maximum stroke, and then fix the two ends of the horizontal bottom bar to the guide rail again;

[0021] 14) Repeat steps 8) to 12). If there are still some parts of the damaged area that have not been removed, loosen the positioning guide rod A from the guide rail and move the positioning guide rod A upward along the guide rail to the maximum travel position by sliding the positioning guide groove and the positioning guide heads at both ends of the bottom of the horizontal bottom rod relative to each other. At this time, the positioning guide heads at both ends of the bottom of the horizontal bottom rod are once again at the bottom of the positioning guide groove.

[0022] 15) Repeat steps 8) to 14) until all damaged areas have been rubbed.

[0023] 16) The finished rubbing pad is removed from the rubbing push plate and the surface water stains are blown dry with compressed air. The corresponding rubbing pads are numbered;

[0024] 17) After drying, refrigerate and harden the rubbing clay. Cut the four sides of the rubbing clay flush with the corresponding edges of the groove plate. Cut the rubbing clay along the groove of the groove plate. If there is overlap between two adjacent rubbing clays, cut off the overlapping part of one of them at random.

[0025] 18) The hardened rubbing clay cut from the groove plate is arranged according to the number and fixed together to form a convex shape that matches the damaged area;

[0026] 19) Scan the ink pad with a laser scanner to obtain the shape of the damaged area;

[0027] 20) The steel plate is then cut according to the shape of the damaged area obtained by the laser scanner to obtain a repair steel plate that matches the damaged area;

[0028] 21) Separate the lifting adjustment frame and horizontal bottom bar fixed to the armor plate from the track, separate the track and positioning guide rod A from the guide rail mounting strip, and cut and separate the guide rail mounting strip 6 from the armor plate; then fill the damaged area with the cut repair steel plate and weld the edges of the repair steel plate to the damaged area;

[0029] 22) Finally, grind the weld scars between the repaired steel plate and the edge of the damaged part, as well as the residual weld scars between the guide rail installation strips and the protective steel plate until they are flush and flat with the end face of the protective steel plate.

[0030] A further improvement of the present invention is that in step 3), when the edge of the damaged portion extends to the edge of the corresponding end face of the pier wall, the guide rail mounting vertical strip corresponding to this side is fixed to the pier wall via a connecting frame.

[0031] A further improvement of the present invention is that in step 3), when the guide rail mounting strips are erected at corresponding positions, the guide rail mounting strips are first temporarily fixed to the face steel plate or the connecting frame by means of a plurality of concave magnets, and then the connecting pieces equally spaced on both sides of the guide rail mounting strips are spot welded to the face steel plate or the connecting frame. After the spot welding is completed, the concave magnets can be removed.

[0032] A further improvement of the present invention is that in step 15), when all positions up to the damaged area have been traced, the horizontal bottom bar and the positioning guide bar A are separated from the guide rail, and the horizontal bottom bar is also separated from the positioning guide bar A; then the guide rail is separated from the guide rail mounting vertical bar, and finally the guide rail mounting vertical bar is separated from the face steel plate, and the welding points between the connecting piece and the face steel plate are polished and smooth.

[0033] A further improvement of the present invention is that in step 4), the guide rail is fixedly connected to the guide rail mounting vertical bar by connecting bolts A.

[0034] A further improvement of the present invention is that in step 5), the horizontal bottom bar is provided with a horizontal strip through hole A along the length direction of the horizontal bottom bar, and the tightening bolt A passes through the horizontal strip through hole A and is tightened and fixed to the guide rail.

[0035] A further improvement of the present invention is that in step 6), the positioning guide rod A is fixedly connected to the side wall of the guide rail by a tightening bolt C, the positioning guide head is fixedly connected to the end face of the connecting block facing the pier wall, and the connecting block is fixedly connected to the bottom of the horizontal bottom rod by a connecting bolt C.

[0036] A further improvement of the present invention is that the positioning guide groove is arranged on the end face of the positioning guide rod A facing away from the pier wall, and the positioning guide groove passes through the positioning guide rod A upward, and the top end of the positioning guide rod A is fixedly connected to an end block by a connecting bolt B, and the end block closes the positioning guide groove.

[0037] A further improvement of the present invention is that in the step 7), the edges of the end face of the rubbing push plate facing the pier wall are respectively movably connected with side rods and end rods, and the side rods and end rods are respectively reciprocated along the corresponding edges facing or facing away from the rubbing push plate by their respective hydraulic cylinders B, and the hydraulic cylinder B is fixed to the rubbing push plate, and the end face of the groove plate facing the rubbing push plate is provided with an annular protrusion, and the side wall cross-section of the annular protrusion is an "L"-shaped structure, and a slot is formed between the annular protrusion and the groove plate, and when the end rod and the side rod are extended to the maximum stroke toward the corresponding edge of the rubbing push plate under the drive of their respective hydraulic cylinders B, the end rod and the side rod respectively extend into the corresponding side slots of the annular protrusion and contact the bottom of the slot, and when the end rod and the side rod are retracted to the maximum stroke toward the corresponding edge of the rubbing push plate under the drive of their respective hydraulic cylinders B, the end rod and the side rod respectively leave the corresponding side slots of the annular protrusion.

[0038] A further improvement of the present invention is that in steps 8), 11), and 12), when the lateral adjustment frame moves to the corresponding position along the lifting adjustment frame, positioning bolts are passed from top to bottom through the positioning guide rod B and the top rod of the lifting adjustment frame and then fixed to the lateral adjustment frame, thereby achieving lateral positioning and fixation of the lateral adjustment frame relative to the lifting adjustment frame.

[0039] A further improvement of the present invention is that in step 8), the lateral adjustment frame is moved laterally to one end along the lifting adjustment frame, and then a positioning guide rod B is placed on the top surface of the top rod of the lifting adjustment frame, corresponding to the position of the lateral adjustment frame, and then the positioning bolt is passed downward through the positioning guide hole provided by the positioning guide rod B and the horizontal strip through hole C of the lifting adjustment frame in sequence, and then connected with the positioning screw hole provided on the top surface of the lateral adjustment frame, and then the positioning guide rod B is moved toward the other end of the lifting adjustment frame until the positioning guide hole of the positioning guide rod B is limited by the positioning bolt, and then the positioning bolt and the positioning screw hole are tightened, so that the positioning bolt clamps the positioning guide rod B and the lateral adjustment frame to the lifting adjustment frame, and then the positioning guide rod B is tightened to the lifting adjustment frame by the tightening bolt D.

[0040] A further improvement of the present invention is that in the step 11), the positioning bolt and the positioning screw hole are loosened, and then the lateral adjustment frame is moved along the positioning guide rod B toward the other end of the lifting adjustment frame until the positioning bolt is limited by the positioning guide hole of the positioning guide rod B, and then the positioning bolt and the positioning screw hole are pre-tightened. The positioning bolt increases the maximum static friction between the positioning guide rod B and the lateral adjustment frame and the lifting adjustment frame, and then the tightening bolt D is loosened, and the positioning guide rod B is moved toward the other end of the lifting adjustment frame until it is limited by the positioning bolt, the lifting adjustment frame or the guide rail. At this time, the positioning guide rod B is fixed to the lifting adjustment frame by the tightening bolt D, and the positioning bolt is tightened.

[0041] A further improvement of the present invention is that in step 12), when the positioning guide rod B is limited by the lifting adjustment frame or the guide rail, the positioning bolt and the positioning screw hole are loosened, and then the lateral adjustment frame is moved along the positioning guide rod B toward the other end of the lifting adjustment frame until it is limited by the positioning guide hole of the positioning guide rod B, and then the positioning bolt and the positioning screw hole are tightened, and the positioning bolt clamps the positioning guide rod B and the lateral adjustment frame to the lifting adjustment frame again.

[0042] A further improvement of the present invention is that in step 18), the rubbing mud remaining in the groove plate is dug out and stirred with the rubbing mud raw material again to soften it, so that the rubbing mud can be loaded into the groove plate again for reuse.

[0043] A further improvement of the present invention is that in step 19), the rubbing pad that has completed laser scanning is stirred again with the rubbing pad raw material to soften it, so that the rubbing pad can be loaded into the slot plate again for reuse.

[0044] A further improvement of the present invention is that when the diver determines the positions of the guide rail mounting bar and the horizontal bottom rod, he touches the two side edges and the bottom edge of the damaged part to determine that the guide rail mounting bar is located outside the two side edges of the damaged part and the horizontal bottom rod is located below the bottom edge of the damaged part, and leaves sufficient distance between the guide rail mounting bar and the damaged part and between the horizontal bottom rod and the damaged part to ensure that the edge of the damaged part will not be missed when rubbing with the rubbing pad.

[0045] The beneficial effects of the present invention are:

[0046] First, the method for repairing torn steel plates of the lock pier wall armoring of the present invention can obtain a repair steel plate that precisely matches the damaged portion by rubbing the shape of the bottom edge of the damaged portion, even if the bottom edge of the damaged portion cannot be seen clearly because it is underwater. When the damaged pier wall armoring steel plate is repaired, the repair steel plate that matches the damaged portion can be accurately cut out and repaired, thereby improving the repair efficiency and quality of the armoring steel plate.

[0047] Secondly, the method for repairing torn steel plates on the facing of the lock pier wall of the present invention is to apply rubbing pads to the damaged part multiple times and make the rubbing positions of each adjacent part of the damaged part adjacent or partially overlap, thereby avoiding missing a part of the damaged part and resulting in the inability to piece together the complete structure of the damaged part after the rubbing pads are finally combined.

[0048] Third, the method for repairing torn steel plates on the lock pier wall of the present invention ensures that the repaired steel plates are in contact with and smooth with the concrete surface by first cutting the damaged portion and processing the edges of the damaged portion to ensure contact with the concrete surface, thereby further ensuring the repair effect of the steel plates and extending the service life of the repaired steel plates.

[0049] Fourth, in the method for repairing torn steel plates of the lock pier wall protective surface of the present invention, the oily rubbing mud is hydrophobic and will not dissolve in water to affect rubbing. In addition, it has good plasticity so that the shape after rubbing can be highly matched with the edge of the damaged part.

[0050] Fifth, in the method for repairing torn steel plates of the lock pier wall facing of the present invention, the rubbing mud is cut and spliced ​​after being refrigerated and hardened, thereby avoiding deformation of the rubbing mud due to mutual contact when splicing, further ensuring that the shape of the protrusion formed by the splicing of the rubbing mud is more accurately matched with the structure of the damaged part, further ensuring that the repair steel plate obtained by subsequent cutting is more accurately matched with the damaged part, and ensuring the repair effect.

[0051] Sixth, the method for repairing torn steel plates on the face of a lock pier wall of the present invention uses laser scanning to form a convex block shape spliced ​​by rubbing ink and laser cutting to form a repairing steel plate, thereby ensuring the matching accuracy of the repairing steel plate to the damaged part.

[0052] Seventh, the method for repairing torn steel plates on the face of a lock pier wall of the present invention can quickly and conveniently fix the guide rail installation uprights when initially determining the guide rail installation uprights through the "concave" magnets, and can also facilitate rapid adjustment of the guide rail installation uprights before final determination.

[0072] like Figures 1 to 19 It can be seen that the method for repairing the torn steel plate of the lock pier wall includes the following steps:

[0073] 1) Cut away the damaged portion 5 of the facing steel plate 4 of the pier wall 2 where warping, bulging, and tearing occur, thereby exposing the concrete 3 corresponding to the damaged portion 5 of the facing steel plate 4;

[0074] 2) trimming the edge of the damaged portion 5 by hammering, bending or cutting so that the edge of the damaged portion 5 fits in with the concrete 3 at the corresponding position;

[0075] 3) Through the cooperation of divers and shore personnel, the guide rail mounting bars 6 are fixed to the pier wall 2 on the outside of the maximum dimension position on both sides of the damaged area 5 of the armor plate 4;

[0076] 4) Fix the guide rail 9 along the guide rail mounting vertical bar 6, and ensure that the bottom end of the guide rail 9 is lower than the maximum dimension of the bottom of the damaged part 5, and the top end of the guide rail 9 is flush with or higher than the top surface of the pier wall 2;

[0077] 5) Move the horizontal bottom rod 11, which is movably connected to the guide rail 9 at both ends, downward along the guide rail 9 until the top surface is lower than the maximum bottom dimension of the damaged part 5, and then connect and fix it to the guide rail 9;

[0078] 6) Removably secure the positioning guide rods A14, each provided with a positioning guide groove 15 parallel to the guide rail 9, to the back side of the guide rail 9. Ensure that the positioning guide heads at both ends of the bottom of the horizontal bottom rod 11 are located at the bottom ends of the positioning guide groove 15. The range of motion of the positioning guide heads within the positioning guide groove 15 is equal to the length of the slot plate 38.

[0079] 7) Removably secure the groove plate 38 containing the rubbing pad 41 to be rubbed to the rubbing push plate 33 of the transverse adjustment frame 26 within the lifting adjustment frame 22, with the rubbing pad 41 facing the facing steel plate 4 with the damaged area 5;

[0080] 8) Then, the lateral adjustment frame 26 is moved laterally to the maximum travel position on one side of the lifting adjustment frame 22 and laterally limited by the positioning guide rod B27. Then, the lifting adjustment frame 22 is moved downward along the guide rail 9 until it contacts the top surface of the horizontal bottom rod 11.

[0081] 9) The hydraulic cylinder A29 fixed to the transverse adjustment frame 26 drives the rubbing push plate 33 and the trough plate 38 containing the rubbing pad 41 to move toward the facing steel plate 4 until the end surface of the rubbing pad 41 is in pressure contact with the concrete 3 corresponding to the damaged area 5 of the facing steel plate 4, and the pressure is maintained for a period of time;

[0082] 10) After the rubbing pad 41 has finished rubbing, the hydraulic cylinder A29 drives the rubbing push plate 33 and the groove plate 38 containing the rubbing pad 41 back to the starting position. The lifting adjustment frame 22 is then moved upward along the track 9 to the top of the pier wall 2. The groove plate 38 containing the completed rubbing pad 41 is separated from the rubbing push plate 33. The groove plate 38 containing the rubbing pad 41 to be rubbed is detachably fixed to the rubbing push plate 33, and the rubbing pad 41 is positioned to face the facing steel plate 4 with the damaged area 5.

[0083] 11) The lateral adjustment frame 26 is then moved toward the other end of the lifting adjustment frame 22 by means of the positioning guide rod B27 until it is adjacent to the previous position of the lateral adjustment frame 26, so that the edge of the rubbing pad 41 facing the starting end of the lateral adjustment frame 26 is aligned with the edge of the previous rubbing pad 41 facing away from the starting end of the lateral adjustment frame 26;

[0084] 12) Repeat steps 8) to 11) until the rubbing pad 41 is finished rubbing after the lateral adjustment frame 26 is moved to the other end of the lifting adjustment frame 22 via the positioning guide rod B27, at which point step 10 is repeated.

[0085] 13) Then loosen the two ends of the horizontal bottom bar 11 from the guide rail 9, and when the positioning guide heads at both ends of the horizontal bottom bar 11 move upward along the positioning guide groove 15 to the maximum stroke, fix the two ends of the horizontal bottom bar 11 to the guide rail (9) again;

[0086] 14) Repeat steps 8) to 12). If there is still a part of the damaged area 5 that has not been rubbed, loosen the positioning guide rod A14 from the guide rail 9 and move the positioning guide rod A14 upward along the guide rail 9 to the maximum travel position through the relative sliding of the positioning guide groove 15 and the positioning guide heads at the bottom of the horizontal bottom rod 11. At this time, the positioning guide heads at the bottom of the horizontal bottom rod 11 are once again located at the bottom end of the positioning guide groove 15.

[0087] 15) Then repeat steps 8) to 14) until all locations of the damaged area 5 have been rubbed;

[0088] 16) The rubbing pad 41 removed from the rubbing push plate 33 is blown dry with compressed air to remove any water stains on the surface, and the corresponding rubbing pad 41 is numbered;

[0089] 17) The dried rubbing pad 41 is refrigerated to harden, and the four sides of the rubbing pad 41 are cut flush with the corresponding edges of the groove plate 38. The rubbing pad 41 is then cut along the groove of the groove plate 38. If there is any overlap between two adjacent rubbing pads 41, the overlapping portion of one of them is cut off at random.

[0090] 18) The hardened rubbing pads 41 cut from the groove plate 38 are arranged according to the numbers and spliced ​​and fixed to form a convex block shape that matches the damaged area 5;

[0091] 19) Scan the ink pad with a laser scanner to obtain the shape of the damaged area 5;

[0092] 20) The steel plate is then cut according to the shape of the damaged portion 5 obtained by the laser scanner, thereby obtaining a repaired steel plate that matches the damaged portion 5;

[0093] 21) Separate the lifting adjustment frame 22 and horizontal bottom bar 11 fixed to the face steel plate 4 from the track 9, separate the track 9 and positioning guide rod A14 from the guide rail mounting strip 6, and cut the guide rail mounting strip 6 and face steel plate 4 apart; then fill the damaged area 5 with the cut repair steel plate, and weld the edges of the repair steel plate to the damaged area 5;

[0094] 22) Finally, grind the weld scars between the repair steel plate and the edge of the damaged area 5 and the residual weld scars between the guide rail installation vertical strip 6 and the protective steel plate 4 until they are flush and flat with the end surface of the protective steel plate 4.

[0095] In step 3), when the edge of the damaged portion 5 extends to the edge of the corresponding end face of the pier wall 2 , the guide rail mounting upright 6 corresponding to this side is fixed to the pier wall 2 via the connecting frame 52 .

[0096] In the step 3), when the guide rail mounting upright 6 is erected at the corresponding position, the guide rail mounting upright 6 is first temporarily fixed to the protective steel plate 4 or the connecting frame 52 through a plurality of "concave" magnets 8, and then the connecting pieces 7 distributed at equal intervals on both sides of the guide rail mounting upright 6 are spot welded to the protective steel plate 4 or the connecting frame 52. After the spot welding is completed, the "concave" magnets 8 can be removed respectively.

[0097] In the step 15), when all positions up to the damaged part 5 have been rubbed, the horizontal bottom bar 11 and the positioning guide bar A14 are separated from the guide rail 9 respectively, and the horizontal bottom bar 11 is also separated from the positioning guide bar A14; then the guide rail 9 is separated from the guide rail mounting vertical bar 6, and finally the guide rail mounting vertical bar 6 is separated from the face steel plate 4, and the welding points between the connecting piece 7 and the face steel plate 4 are polished and smooth.

[0098] In step 4), the guide rail 9 is fixedly connected to the guide rail mounting vertical bar 6 via connecting bolts A.
