Description

Technical Field

[0001] This invention relates to a peeling device, and more particularly to a device and method for peeling off adhesive spacer plates from movable forks, belonging to the field of spacer plate disassembly technology. Background Technology

[0002] Generally speaking, the GLC(08)01 type turnout is a single-opening turnout with a movable frog on a 60kg / m rail of No. 12, and the maximum allowable speed is 200km / h. It is one of the important weak points of railway equipment. The movable frog of this type of turnout produced by Baoqiao mainly consists of straight wing rail, long frog rail, 60AT-224 type frog spacer, pad plate (746), side wing rail, short frog rail, fork tip rail, 950-234 type frog spacer, pad plate (1443, 1493, 762) and top iron, etc.

[0003] Because this turnout is an extra-long seamless turnout, the straight wing rail and the end of the long frog rail are connected and glued using two 60AT-224 type frog spacers and 24 M27 bolts. The side wing rail and the end of the fork and point rail are connected and glued using two 950-234 type frog spacers and 24 M27 bolts to maintain the turnout's condition. With increased operating time, damage to the wing rails, frog rails, and fork and point rails of the movable frog gradually increases, requiring them to be separated from the frog spacers during replacement. Currently, there are no specialized tools available for operators to use.

[0004] Currently, a search reveals that utility model patent CN202122659716.0 discloses a high-performance spacer, including a shell, a first top iron, and a second top iron. This high-performance spacer facilitates spacer adjustment, but it is an improvement on the spacer itself and cannot be used as a tool for peeling off the spacer. Peeling off the glued spacer of the movable frog of the GLC(08)01 turnout typically involves repeatedly striking, hitting, pulling, and prying with simple tools such as sledgehammers and crowbars. Because the tools are simple and relatively outdated, this is not only time-consuming and labor-intensive, but also inefficient, and prone to causing injury to workers' hands and feet due to crowbar slippage. Furthermore, the delay in track maintenance windows affects train transportation. Summary of the Invention

[0005] In view of the many defects and shortcomings of the above-mentioned background technology, the present invention has made improvements and innovations, and provides a movable fork joint adhesive spacer peeling device with simple structure, novel and reasonable design, which can destroy the high-strength adhesive between the rail and the spacer and separate the spacer from the rail. This improves the work efficiency and eliminates the safety risk of personal injury accidents caused by the sliding of the crowbar in traditional operations.

[0006] Another objective of this invention is to provide a horizontal and vertical adjustable engagement distance between the positioning part and the rail through the design of the second rail head positioning structure and the second rail bottom positioning structure.

The present invention adopts a design structure of a second rail head positioning structure and a second rail bottom positioning structure, which can better adapt to various complex environmental conditions and ensure that the two positioning structures can work in the optimal clamping position of the rail, saving a lot of labor and time costs.

[0069] 4. The present invention adopts a design structure of second rail head positioning structure and second rail bottom positioning structure, which can provide greater flexibility and can be finely adjusted according to actual needs. This design makes the disassembly of the spacer easier and reduces possible errors during the disassembly process. At the same time, precise adjustment of the distance between the locking part and the rail can effectively avoid wear and stress concentration caused by uneven contact or excessive tightness.

[0070] 5. The external structure of the support top member of the present invention can fit the different dimensions of the long center rail, straight wing rail, curved wing rail and fork and point rail, providing a vertical force-bearing surface for the jack and transmitting the force of the jack to the rail through the support top member.

[0071] 6. This invention is a modular form, with a compact appearance and convenient operation. It can be disassembled and placed into the narrow space of the internal spacer between the long center rail and the straight wing rail, or between the curved wing rail and the fork and the point rail, and then combined for use.

[0072] 7. This invention is flexible and convenient, allowing two sets of devices to be used simultaneously without interference, and they can also complement each other.

[0073] 8. This invention can improve operational efficiency and reduce the accountability and performance evaluation issues caused by delays in track maintenance windows affecting train transportation;

[0074] 9. This invention uses a hydraulic jack to provide power, eliminating the safety risk of personal injury accidents caused by the slippage of the crowbar in traditional operations, which could crush the hands and feet of the workers.

[0075] 10. This invention adopts a design structure with a second rail head positioning structure and a second rail bottom positioning structure. The second rail head positioning structure can adjust the support position forward and backward, and the second rail bottom positioning structure can slide up and down to adjust the support position. This allows the shape of the sliding support top component to be used on different types of turnouts, fitting the different dimensions of long center rails, straight wing rails, curved wing rails, and fork and point rails, thus having a wide range of applications. The sliding support top component provides a vertical force-bearing surface for the jack, transmitting the force of the jack to the rail through the second rail head positioning structure and the second rail bottom positioning structure on the sliding support top component, resulting in good force transmission effect.

[0156] The jack 5 is connected to the hand pump 52 via the hydraulic pipeline 51, and the hand pump 52 is used to control the extension and retraction of the jack 5.

[0157] In this invention, the tray 2 has an opening facing upwards, and its arc-shaped end face is adapted to the shape of the jack 5 to support the jack 5.

[0158] In this invention, the distance from the bottom of the socket groove of the top fitting 3a to its front end is adapted to the difference in the horizontal distance between the bottom side and the head side of the two types of rails, namely the long center rail 6 and the straight wing rail 7; the front end face of the horizontal rod of the fixed support top member and the front end face of the top fitting 3a are both arc-shaped surfaces, and their arc-shaped surface shape is adapted to the curvature of the two sides of the top of the rail.

[0159] In this invention, the distance from the bottom of the concave groove to the front end face of the transverse rod of the fixed support top member is adapted to the transverse distance from the side of the bottom of the fork tip rail 61, the straight wing rail 7, or the curved wing rail 71 to the side of the top of the same side rail; the distance from the first concave groove 4a to the top of the fixed support top member is adapted to the height of the fork tip rail 61, the straight wing rail 7, or the curved wing rail 71; and the distance from the second concave groove 4b to the top of the fixed support top member is adapted to the height of the long center rail 6.

[0160] In this invention, such as Figure 4 , Figure 5 As shown, the support top member 1 is a single cast steel piece with a height of 190mm, a top width of 65mm, a bottom width of 35mm, and a thickness of 35mm. At 10mm from the bottom surface, there is a first concave groove 4a with a height of 14mm and a depth of 5mm. In the working state, the first concave groove 4a is engaged with the side foot of the fork tip rail 61, the straight wing rail 7, or the curved wing rail 71. At 45mm from the bottom surface, there is a second concave groove 4b with a height of 23mm and a depth of 5mm. The first concave groove 4a has a width of 14mm, and the second concave groove 4b has a width of 23mm. In the working state, the second concave groove 4b is engaged with the side foot of the long center rail 6. The contact surface between the upper transverse rod of the support top member 1 and the rail head is arc-shaped, and its arc shape matches the side of the rail head, with a contact area of ​​30×40mm. 2 .

[0161] In this invention, the top fitting 3a is rectangular, 36×36mm×37mm in length, with a solid front end (14mm) and a hollow socket (23mm) at the rear end. The distance from the bottom of the socket to the front end of the top fitting 3a is 14mm. In operation, the socket of the top fitting 3a is fitted onto the front end of the transverse rod of the supporting top member 1, and the second concave groove 4b on the supporting top member 1 is engaged with the side rail foot of the long central rail 6, ensuring close contact between the top fitting 3a and the side of the rail head.

[0162] In this invention, such as Figure 4 , Figure 5 As shown, the support plate 2 is a semi-circular thin iron sheet with a length of 64mm and a thickness of 2mm. The front end is welded to a position 65mm away from the lower part of the support top piece 1. A 40×40mm triangular diagonal brace 33 is provided below it to support the jack 5. The opening of the support plate 2 faces upward, and its arc-shaped end face is adapted to the shape of the jack 5 to support the jack 5.

[0163] In this invention, the jack 5 is a detachable short hydraulic jack, which serves as the power unit of this device. The jack 5 has a tonnage of 10T, a body height of 107mm, a stroke of 50mm, a weight of 2.5kg, a cylinder outer diameter of 64mm, and a plunger diameter of 38mm. The hand-cranked pump 52 is an accessory to the detachable short hydraulic jack 5, which supplies or recovers hydraulic oil to the jack 5 through a high-pressure hydraulic pipeline 51; the jack cylinder is connected to the hand-cranked pump 52 through the hydraulic pipeline 51.

[0164] The working principle is as follows: In this embodiment, the fixed support top piece serves as the support component, and the jack 5 serves as the power component. The two are combined and placed in the narrow space of the spacer 8 between the long center rail 6 and the straight wing rail 7, and the curved wing rail 71 and the fork tip rail 61, as an auxiliary tool for peeling off the spacer 8. When in use, the operator supports the side of the rail head with the fixed support top piece through the front end face of the top horizontal bar or the front end face of the jack kit 3a, and supports the side of the rail bottom through the concave groove at the lower end of the vertical bar of the fixed support top piece, so that the fixed support top piece avoids the spacer 8 and provides a force-bearing surface for the jack 5. The jack kit 3a eliminates the difference in the horizontal distance between the side of the rail bottom and the side of the head of the two types of rails, which are the working surfaces of the long center rail 6 and the straight wing rail 7, so that the fixed support top piece keeps the vertical bar vertical when supporting two types of rails. The jack 5 is placed inside the support plate 2, with one end acting on the vertical rod of the fixed support top component and the other end acting on the spacer 8, separating the non-abutting rail or the end of the spacer 8 from the rail.

[0165] How this embodiment works:

[0166] 1. For example Figure 2 As shown, when the above structure is used for stripping the rail feed rail of type 60AT-224 frog, it specifically includes the following steps:

[0167] Step 1: Preparation. Because the long center rail 6 has a variable cross-section within the area between the two spacer blocks 8, with a height of 152mm, a rail base thickness of 18mm, and the pad plate thickening upwards by 26mm, the rail base of the long center rail 6 is 50mm higher than that of the straight wing rail 7. First, remove the T-bolts, Type II elastic clips, and Type III elastic clips from the lower pad plates of the long center rail 6 and straight wing rail 7 within the area before and after the spacer blocks 8. Remove the gauge blocks, loosen and remove the 24 M27 hex bolts on the spacer blocks 8.

[0168] Step 2: Use two hydraulic track lifters to raise the straight wing rail 7 and the long center rail 6 by 30-40mm from both sides, so that the bottom of the straight wing rail 7 and the long center rail 6 is higher than the iron stop welded to the pad plate.

[0169] Step 3: Place the slot of the top head kit 3a onto the top head position at the front end of the crossbar of the support top piece 1, and then place it in the middle of the 60AT-224 type frog spacer 8. The second concave groove 4b at the lower part of the support top piece 1 is engaged with the side rail foot of the long center rail 6, and the top head kit 3a is in close contact with the side rail head of the long center rail 6.

[0170] Step 4: Place the split short hydraulic jack 5 on the support plate 2, with the telescopic end against the middle of the vertical rod of the support top piece 1 and the rear end against the middle of the spacer 8. Insert the hydraulic line 51 into the oil inlet of the split short hydraulic jack 5 and insert the anti-dislodgement cap.

[0171] Step 5: Close the return oil valve, crank the operating handle of the hand pump 52, with the middle of the spacer 8 as the support back, the telescopic rod of the short hydraulic jack 5 extends, and the lateral thrust is transmitted from the support top piece 1 to the side rail head and rail foot of the long core rail 6. After the long core rail 6 and the spacer 8 are subjected to force, they gradually separate, completely destroying the high-strength adhesive.

[0172] Step 6: Loosen the return valve of jack 5 to reset the piston, and remove hydraulic jack 5 and support top piece 1;

[0173] Step 7: Remove the top assembly 3a from the support top piece 1. Using only the support top piece 1, reverse the direction and repeat steps 3-6 until the straight wing rail 7, the long center rail 6, and the two spacer irons 8 are completely separated.

[0174] 2. For example Figure 3 As shown, when the structure of the present invention is used for stripping the spacer iron of a 950-234 type turnout, the specific steps include:

[0175] Step 1: Preparation; First, remove the T-bolts, Type II spring clips, and Type III spring clips from the lower pads of the fork and point rail 61 and the curved wing rail 71 within the front and rear range of the spacer 8, take out the gauge block, loosen and remove the 24 M27 hex bolts on the spacer 8.

[0176] Step 2: Use two hydraulic track lifters to raise the curved wing rail 71 and the fork and point rail 61 by 30-40mm from both sides, so that the bottom of the curved wing rail 71 and the fork and point rail 61 is higher than the iron stop welded to the pad plate.

[0177] Step 3: Place the support top piece 1 of the fork and point rail 61 in the middle of the 950-234 type fork rail spacer 8. The first concave groove 4a of the lower part of the support top piece 1 is engaged with the side rail foot of the fork and point rail 61. The upper front end face of the support top piece 1 is in close contact with the side of the rail head of the fork and point rail 61.

[0178] Step 4: Place the split short hydraulic jack 5 on the support plate 2, with the telescopic end against the middle of the support top piece 1 and the rear end against the middle of the spacer 8. Insert the hydraulic line 51 into the oil inlet of the split short hydraulic jack 5 and insert the anti-dislodgement cap.

[0179] Step 5: Close the return oil valve, crank the operating handle, with the middle of the spacer 8 as the support back, the piston of the short hydraulic jack 5 extends, and the lateral thrust is transmitted from the support top piece 1 to the side rail head and rail foot of the fork and point rail 61. After the fork and point rail 61 is subjected to force, it gradually separates from the spacer 8, completely destroying the high-strength adhesive.

[0180] Step 6: Loosen the return valve to reset the piston, and remove the support top piece 1 of the hydraulic jack 5 and the fork and the point rail 61;

[0181] Step 7: Change direction and repeat steps 3 to 6 above until the curved wing rail 71, fork and point rail 61 are completely separated from the two spacer bars 8.

[0182] Finally, as time goes on, once all the stripping work is completed, the operator simply needs to transport the invention to the designated tool storage warehouse using appropriate handling equipment or manually for storage, so that it can be reused in the next cycle.

[0183] During the above-mentioned use, the operator can use two sets of devices simultaneously to perform the peeling of the adhesive spacer 8, thereby improving work efficiency.

[0184] Example 2

[0185] As per the instruction manual Figures 6 to 13 The movable fork joint adhesive spacer stripping device shown includes a jack 5 and a support top member 1;

[0186] Support plate 2 is connected to the outer side of one end of the supporting top piece 1;

[0187] Rail head positioning structure 3 is set above the other end of the support top member 1;

[0188] The rail bottom positioning structure 4 is located below the other end of the support top component 1.

[0189] Among them, the jack 5 is set on the support plate 2. One end of the jack 5 is in contact with the supporting top part 1, and the other end of the jack 5 is in contact with the rail or spacer 8 to complete the stripping work of the non-contact end of the rail or spacer 8.

[0190] Furthermore, the supporting top member 1 is a sliding supporting top member. The sliding supporting top member has an overall “7” or “L” shaped structure. The horizontal rod of the sliding supporting top member has a sliding hole 11 along its length direction, and the lower part of the inner side of the vertical rod of the sliding supporting top member has a sliding groove 14.

[0191] The rail head positioning structure 3 is a second rail head positioning structure, which is laterally adjustable within the sliding hole 11;

[0192] The rail bottom positioning structure 4 is a second rail bottom positioning structure, which is adjustablely connected to the slide groove 14.

[0193] In this invention, such as Figure 11As shown, the supporting top part 1, the support plate 2, and the reinforcing rib 21 are welded together to form a whole. The supporting top part 1 is a solid cast steel with a height of 190mm, a width of 40mm, and a thickness of 40mm. A sliding hole 11 with a diameter of 22mm is provided through the front and back of the top. The lower inner side has a positioning block groove 141 with a height of 80mm, a depth of 15mm, and a width of 25mm. The positioning block groove 141 has a 6mm wide waist-shaped hole 142 that is vertically connected on both sides.

[0194] Specifically, one end of the horizontal rod of the sliding support top member is also provided with a U-shaped mounting part, and a rotation limiting groove 12 is provided on the U-shaped mounting part. The rotation limiting groove 12 is U-shaped and is connected to the sliding hole 11.

[0195] The lower inner part of the sliding hole 11 is also connected to a limiting strip 13;

[0196] The slide groove 14 is generally T-shaped. The slide groove 14 is formed by the positioning block slide groove 141, which is recessed inward along the inner side of the vertical rod of the sliding support top member, and the waist-shaped hole 142 that passes through both sides of the lower part of the sliding support top member.

[0197] Furthermore, the second railhead positioning structure includes:

[0198] Positioning plate 31;

[0199] Adjusting screw 32, one end of which is connected to positioning plate 31;

[0200] Adjusting nut 33 is threaded onto adjusting screw 32;

[0201] Snap ring 34 is fixedly connected to one end face of adjusting nut 33;

[0202] The retaining ring 34 is engaged in the rotation limiting groove 12.

[0203] Specifically, the non-connecting end of the positioning plate 31 is an arc-shaped surface, the shape of which is adapted to the curvature of the top working surface of the rail;

[0204] The adjusting screw 32 is also provided with a limiting groove 35 along its length direction, which is adapted to and engages with the limiting strip 13;

[0205] Adjusting nut 33 is adapted to the diameter of sliding hole 11.

[0206] In an embodiment, such as Figure 11As shown, the positioning plate 31 is used to increase the contact area between the second rail head positioning structure and the side of the rail head. The adjusting screw 32 and the adjusting nut 33 are used to adjust the position of the positioning plate 31. The limiting strip 13 in the sliding hole 11 is used to limit the rotation of the adjusting screw 32 to prevent the positioning plate 31 from shifting during the adjustment process. The arc angle of the front end of the positioning plate 31 is offset and does not match the side of the rail head. The rotation limiting groove 12 is used to limit the front and rear position of the adjusting nut 33. The adjusting screw 32 and the adjusting nut 33 form a self-locking structure through the rotation limiting groove 12. The adjusting nut 33 controls the front and rear movement of the adjusting screw 32. The adjusting screw 32 limits the adjusting nut 33 in the rotation limiting groove 12. The adjusting screw 32 and the adjusting nut 33 will not fall off when the support top 1 is flipped.

[0207] In this invention, such as Figure 10 As shown, the front end face of the positioning plate 31 is an arc-shaped surface, and its arc shape is adapted to the curvature of the two sides of the top of the rail, which is used to increase the contact area between the positioning plate 31 and the top of the rail and improve the force transmission effect.

[0208] Furthermore, the second rail bottom positioning structure includes:

[0209] Positioning block 41 is vertically slidably connected within positioning block groove 141;

[0210] Locking element 42 is symmetrically connected to both ends of positioning block 41;

[0211] The locking member 42 is used to limit and lock the positioning block 41 at the designated position of the waist-shaped hole 142.

[0212] Specifically, the positioning block 41 has a positioning groove 411 that is adapted to the bottom of the rail on one end face;

[0213] The locking element 42 includes:

[0214] A fixing screw 421 is fixedly connected to the positioning block 41 by passing through the corresponding oblong hole 142 at one end.

[0215] The wing nut 422 is threaded onto the fixing screw 421 and is located on the outer side of the lower part of the sliding support top member.

[0216] In this invention, such as Figure 11 As shown, the positioning slot 411, which is horizontally set on the front end face of the positioning block 41, is used to position the bottom of the rail. The width of the positioning slot 411 is greater than the outer thickness of the bottom of the long center rail 6. The bottom thickness of the long center rail 6 is greater than the bottom thickness of the fork point rail 61, the straight wing rail 7 and the curved wing rail 71. The positioning block 41 is limited on both sides by fixing screws 421 passing through two waist-shaped holes 142. The wing nut 422 makes it easy for construction personnel to adjust the position of the positioning block 41.

[0217] Furthermore, the support plate 2 is an elongated arc-shaped plate, the shape of which is adapted to the shape of the jack 5. The bottom of the support plate 2 is also connected to the supporting top member 1 by a reinforcing rib 21.

[0218] The jack 5 is a separate short hydraulic jack, and the tonnage of the jack 5 is not less than 5T;

[0219] The jack 5 is connected to the hand pump 52 via the hydraulic pipeline 51, and the hand pump 52 is used to control the extension and retraction of the jack 5.

[0220] In this invention, the support plate 2 is a semi-circular thin iron sheet with a length of 64mm and a thickness of 2mm. The front end is welded to a position 65mm away from the lower part of the support top piece 1. A 40x40mm reinforcing rib 21 is provided below it. The reinforcing rib 21 is used to strengthen the structural strength of the support plate 2 and support the jack 5.

[0221] In this invention, the jack 5 is a separate short hydraulic jack, which is the power unit of this device. The jack 5 has a tonnage of 10T, a body height of 107mm, a stroke of 50mm, a weight of 2.5kg, an outer diameter of 64mm for the cylinder, and a plunger diameter of 38mm.

[0222] Finally, as time goes by, once the invention is no longer in use, the operator only needs to transport the stripping device of the invention's design structure to a designated tool storage warehouse for storage, either using appropriate handling equipment or manually, for future use.

[0223] When the above structure is in use, the operator supports the side of the rail head with the top of the sliding support top piece through the front face of the positioning plate 31 of the second rail head positioning structure, and supports the side of the rail bottom with the bottom of the sliding support top piece through the positioning slot 411 of the positioning block 41 of the second rail bottom positioning structure, so that the sliding support top piece avoids the spacer 8 at this end to provide a force-bearing surface for the jack 5; the sliding support top piece eliminates water on the side of the rail bottom and the side of the head of the two types of rails, the long center rail 6 and the straight wing rail 7, by adjusting the position of the second rail head positioning structure back and forth; The difference in the horizontal spacing ensures that the vertical rod of the sliding support top piece remains vertical when supporting two sizes of rails. By adjusting the position of the second rail base positioning structure, the upper and lower ends of the sliding support top piece can position the rail head and rail foot of different sizes of rails. The jack 5 is placed in the support plate 2, with one end acting on the vertical rod of the sliding support top piece and the other end acting on the corresponding spacer 8. The hand pump 52 is cranked to drive the jack 5 to extend through the hydraulic pipeline 51, forcibly breaking the high-strength adhesive between the rail and the spacer 8, thus separating the spacer 8 from the rail.

[0224] During the above-mentioned use, the second rail head positioning structure adjusts the front and rear position of the positioning plate 31 by rotating the adjusting nut 33. When the adjusting nut 33 is rotated, the rotating retaining ring 34 on the adjusting nut 33 rotates in place in the rotating limiting groove 12 on the top of the sliding support top piece. The adjusting screw 32 and the adjusting nut 33 are threaded together and move back and forth in the sliding hole 11. At the same time, the limiting groove 35 on the adjusting screw 32 cooperates with the limiting strip 13 in the sliding hole 11 to restrict the rotation of the adjusting screw 32, so that the adjusting screw 32 can only move back and forth and drive the positioning plate 31 to move its position.

[0225] The second track bottom positioning structure adjusts the height of the positioning slot 411 by sliding the positioning block 41 up and down in the sliding groove 14 of the sliding support top piece. When the positioning block 41 slides, the fixing screw 421 follows the positioning block 41 and slides up and down in the waist-shaped hole 142. After the positioning block 41 slides into place, the height of the positioning block 41 is fixed by tightening the wing nut 422.

[0226] The working principle of this embodiment is as follows: Figures 6 to 8 As shown, when the above structure is used to strip the frog spacer, it specifically includes the following steps:

[0227] Step 1: Preparation. Because the long center rail 6 has a variable cross-section within the area between the two spacer blocks 8, with a height of 152mm, a rail base thickness of 18mm, and the pad plate thickening upwards by 26mm, the rail base of the long center rail 6 is 50mm higher than that of the straight wing rail 7. First, remove the T-bolts, Type II elastic clips, and Type III elastic clips from the lower pad plates of the long center rail 6 and straight wing rail 7 within the area before and after the spacer blocks 8. Remove the gauge blocks, loosen and remove the 24 M27 hex bolts on the spacer blocks 8.

[0228] Step 2: Use two hydraulic track lifters to raise the straight wing rail 7 and the long center rail 6 by 30-40mm from both sides, so that the bottom of the straight wing rail 7 and the long center rail 6 is higher than the iron stop welded to the pad plate.

[0229] Step 3: First, place the support top piece 1 in the middle of the frog spacer 8, loosen the wing nut 422, then lock the positioning slot 411 of the second rail bottom positioning structure into the side rail foot of the long center rail 6, and pull the support top piece 1 up and down so that the positioning plate 31 of the second rail head positioning structure is at the same height as the rail head of the long center rail 6. Then, rotate the adjusting nut 33 of the second rail head positioning structure to adjust the front and rear position of the positioning plate 31 so that the front end of the positioning plate 31 contacts the side of the rail head of the long center rail 6 while the support top piece 1 is in a vertical state. Then tighten the wing nut 422.

[0230] Step 4: Place the split short hydraulic jack 5 on the support plate 2, with the telescopic end against the middle of the support top piece 1 and the rear end against the middle of the spacer 8. Then, insert the other end of the hydraulic line 51 connected to the hand pump 52 into the oil inlet of the jack 5 and insert the anti-dislodgement cap.

[0231] Step 5: Close the return oil valve of jack 5, crank the operating handle of hand pump 52, with the middle of spacer 8 as the support back, the telescopic rod of hydraulic jack 5 extends, and the lateral thrust is transmitted from the support top piece 1 to the side rail head and rail foot of long core rail 6. After the long core rail 6 and spacer 8 are subjected to force, they gradually separate, completely destroying the high-strength adhesive.

[0232] Step 6: After the long core rail 6 is completely separated from the spacer iron 8, loosen the return oil valve of the jack 5 to reset the piston, and remove the hydraulic jack 5 and the support top piece 1.

[0233] Step 7: Change direction and repeat steps 3-6 until the straight wing rail 7, the long center rail 6, and the two spacer rails 8 are completely separated.

[0234] During the above-mentioned use, the method for removing the spacer 8 between the fork and the point rail 61 and the curved wing rail 71 is the same as in steps 1-7 above, and will not be repeated here.

[0235] This invention allows for the simultaneous use of two sets of devices to peel off the adhesive-bonded spacer 8 at both ends, thereby improving work efficiency.

[0236] Finally, as time goes on, once all the stripping work is completed, the operator only needs to transport the stripping device of the present invention to the designated tool storage warehouse for storage by means of appropriate handling equipment or directly by manual labor, for the next cycle of use.

[0237] Finally, it should be noted that the above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present invention without departing from the scope of the present invention shall still fall within the protection scope of the present invention.
