Description

Technical Field

[0001] This invention relates to the field of track breaking tools, and more particularly to a track adhesive insulation joint breaking tool. Background Technology

[0002] The stable operation of railway signaling systems is highly dependent on track circuits. Their core functions include precise train positioning and track clearance detection. However, continuous rails can cause signal transmission interference, so it is necessary to use insulating components for segmented isolation to avoid signal crosstalk and ensure train dispatching safety. As a core component, the insulating head must meet the dual stringent requirements of electrical insulation performance and structural load-bearing strength. With the breakthrough development of high-performance insulating adhesive technology, the integrated design of "adhesive + insulating head" has emerged. Combining the strong bonding characteristics of adhesives with the functional advantages of insulating heads, it not only solves the inherent defects of traditional solutions but also better adapts to the needs of demanding operating scenarios such as high speed and heavy load. It has gradually replaced traditional solutions and become the preferred upgrade for track insulation connections.

[0003] After prolonged use, bonded insulated joints can experience reduced insulation resistance due to aging and carbonization of the insulated joint material, or adhesive failure caused by moisture, leading to problems such as interference with track circuit signals. These require removal and replacement using a specialized hydraulic wedge-type demolition tool. However, existing demolition tools rely solely on continuous hydraulic thrust to drive the wedge forward, resulting in a gentle and dispersed thrust. When facing insulated joints bonded to the track with high strength (such as fully cured adhesive or rusted adhesion to the rail), it is difficult to quickly break the interface adhesion, reducing the equipment's demolition efficiency and increasing maintenance time. Furthermore, the wedges on existing hydraulic wedge-type demolition tools are mostly fixed rigid structures. When the gap between the bonded insulated joint and the track is small, the wedge struggles to find an effective entry point, increasing the initial insertion time and further reducing demolition efficiency. Therefore, we propose a track bonded insulated joint demolition tool to address these issues. Summary of the Invention

[0004] The purpose of this invention is to solve the problems mentioned in the background art by providing a track adhesive insulation joint breaker.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A rail adhesive-bonded insulation joint demolition device includes a rail, two adhesive plates, and a device body. Two threaded rods are rotatably mounted through the device body. Push plates are threaded onto each of the two threaded rods. Fixing boxes are fixedly mounted on each of the two push plates. Wedge-shaped cutters are fixedly mounted inside each of the two fixing boxes. A driving component, a striking component, and a cutting component are all provided inside each of the two fixing boxes.

[0007] Both of the aforementioned striking components include two spring telescopic rods, and the two spring telescopic rods are fixedly installed on the inner wall of the corresponding fixed box. A striking block is fixedly installed between the two spring telescopic rods.

[0008] Both cutting assemblies include a rotating shaft, which is rotatably mounted on the inner wall of the corresponding fixed box. Both rotating shafts are equipped with cutting mechanisms and pushing components.

[0009] Compared with existing technologies, the advantages of this invention are:

[0010] 1. In the process of breaking up bonded plates, this invention utilizes the intermittent instantaneous impact force generated by the drive component and the striking component on the wedge-shaped cutter head. This instantaneous high-intensity forward force is superimposed on the continuous hydraulic advancement of the wedge-shaped cutter head, concentrating energy at the front end of the wedge-shaped cutter head. This directly breaks the bonds between adhesive molecules or loosens rusted adhesions, achieving a synergistic effect of "continuous advancement + instantaneous breakthrough." This increases the breaking speed of the wedge-shaped cutter head on the corresponding bonded plates. Simultaneously, through the cooperation of the striking block and the cutting component, the blade is driven to rotate reciprocally, which gradually increases the bonding gap between the bonded plate and the rail, improving the smoothness of the wedge-shaped cutter head insertion between the bonded plate and the rail. This further helps to increase the breaking speed of the wedge-shaped cutter head on the corresponding bonded plates.

[0011] 2: In the process of breaking the bonded board, the present invention can automatically and indirectly detect the forward breaking resistance of the wedge-shaped cutter head through the cooperation of the sensing component and the pushing component. When the increased rotational resistance of the blade is detected, the striking frequency of the striking block on the wedge-shaped cutter head is adaptively increased to ensure the breaking speed of the wedge-shaped cutter head on the corresponding bonded board at this stage, that is, to ensure the continuous breaking speed of the bonded board by the device.

[0032] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0033] Reference Figures 1-16 A rail adhesive-bonded insulated joint demolition tool includes a rail 1 and two adhesive plates 2 (connected to the rail). Figure 1 It can be seen that the steel rail 1 consists of two rails, and two adhesive plates 2 are installed between the two rails. The equipment body 3 has two threaded rods 5 that are installed through and rotate on the equipment body 3. Push plates 6 are threaded on both threaded rods 5. Fixing boxes 7 are fixedly installed on both push plates 6. Wedge-shaped cutter heads 4 are fixedly installed in both fixing boxes 7. Drive components 8 are set in both fixing boxes 7. A striking component 9 is set in both fixing boxes 7. A cutting component 10 is set in both fixing boxes 7.

[0034] Both drive components 8 include a micro motor 81, and the micro motor 81 is fixedly mounted on the main body 3 of the device. A rotating shaft 82 is fixedly mounted on the drive end of each of the two micro motors 81. A circularly distributed sliding groove 83 is opened on each of the two rotating shafts 82. A fixed cylinder 84 is slidably mounted between the corresponding multiple sliding grooves 83. A pushing block 87 that cooperates with the corresponding fixed cylinder 84 is fixedly mounted on each of the two push plates 6. A rotating gear 1 85 is fixedly mounted on each of the two fixed cylinders 84. A rotating gear 2 86 is fixedly mounted on each of the two fixed cylinders 84. A drive mechanism is installed in each of the two fixed boxes 7.

[0035] Both drive mechanisms include a round rod 88, which is rotatably mounted on the inner wall of the corresponding fixed box 7. A cylinder 89 is slidably mounted on each of the two round rods 88. A disc 810 is fixedly mounted on each of the two cylinders 89. A spur gear 812 that meshes with the corresponding rotating gear 85 is fixedly mounted on each of the two cylinders 89. A parallel shaft gear 813 that meshes with the corresponding rotating gear 86 is fixedly mounted on each of the two cylinders 89. A force transmission component is mounted on each of the two cylinders 89.

[0036] When it is necessary to use this equipment to dismantle the adhesive plate 2 (which is the same product as the insulating head mentioned in the background art, only the description is different) on the rail 1, first manually remove the bolts connecting the adhesive plate 2 and the rail 1 (connected to the rail 1). Figure 1 (As can be seen) dismantle, and then erect the main body 3 of the equipment on the steel rail 1, and fix the left end of the main body 3 of the equipment on the steel rail 1 (as shown). Figure 1 (as shown in the direction), and then by rotating the two threaded rods 5, the positions of the two wedge-shaped cutter heads 4 are adjusted until the two wedge-shaped cutter heads 4 are respectively in contact with the side wall of the corresponding rail 1.

[0037] At the same time, combined Figure 3 and Figure 4 It can be seen that a rod is installed on the inner wall of the main body 3 of the equipment, and two push plates 6 are slidably installed on the rod. The purpose is that when the position of the wedge head 4 needs to be adjusted, the corresponding push plate 6, the fixed box 7 and the wedge head 4 are driven to move horizontally by rotating the corresponding threaded rod 5. The cooperation between the rod and the push plate 6 can help improve the stability of the horizontal movement of the corresponding fixed box 7 and the wedge head 4.

[0038] After the positions of the two wedge-shaped cutter heads 4 are adjusted, the right end of the equipment body 3 (including the two wedge-shaped cutter heads 4, the two fixed boxes 7, and the blade 1010) can be driven to move to the right via the hydraulic system (existing conventional mechanical structure) on the equipment body 3 (e.g., ...). Figure 1 (In the direction shown), when the two blades 1010 are about to be bonded to the bonding interface of the corresponding adhesive plate 2, the two micro motors 81 are started.

[0039] Reference Figures 1-16 Both striking components 9 include two spring telescopic rods 91, and the two spring telescopic rods 91 are fixedly installed on the inner wall of the corresponding fixed box 7. A striking block 92 is fixedly installed between the two spring telescopic rods 91.

[0040] Both power transmission components include an incomplete gear 811, and the incomplete gear 811 is fixedly mounted on the corresponding cylinder 89. Both striking blocks 92 are fixedly mounted with a first rack 93 that mates with the corresponding incomplete gear 811.

[0041] like Figure 10 As shown, in the initial state, the two rotating gears 85 mesh with the corresponding spur gears 812. When the two micro motors 81 start running, their operation drives the corresponding cylinder 89 and rod 88 to rotate through the corresponding rotating shaft 82, fixed cylinder 84, rotating gear 85, and spur gear 812. During the continuous rotation of the cylinder 89 and the corresponding incomplete gear 811, the intermittent horizontal driving force applied to the corresponding first rack 93 by the upper tooth block of the incomplete gear 811, and the intermittent rebound force applied to the first rack 93 by the two spring telescopic rods 91, can drive the first rack 93 to move the corresponding striking block 92 back and forth, intermittently striking the right end of the wedge-shaped cutter head 4 (e.g., ...). Figure 12 direction shown).

[0042] When the wedge-shaped cutter head 4 contacts the surface adhesive interface of the corresponding adhesive plate 2, the instantaneous impact force generated by the intermittent striking of the wedge-shaped cutter head 4 by the corresponding striking block 92 can, on the basis of the continuous hydraulic advancement of the wedge-shaped cutter head 4, superimpose an instantaneous high-intensity forward force, concentrating energy at the front end of the wedge-shaped cutter head 4, directly cracking the adhesive molecular bonds or loosening rusted adhesions, achieving a synergistic effect of "continuous advancement + instantaneous breakthrough". This can help significantly reduce the forward movement resistance of the wedge-shaped cutter head 4 and increase the breaking speed of the adhesive plate 2 as the wedge-shaped cutter head 4 continues to move to the right (e.g., Figure 1 (as shown in the direction) Meanwhile, when faced with scenarios such as aging and embrittlement of the adhesive plate 2 and uneven adhesive layer caused by factors such as temperature and humidity cycles and rain and snow erosion, the intermittent impact of the wedge-shaped cutter head 4 can flexibly cope with the differences in connection strength in different areas, and will not cause the adhesive plate 2 to shatter and fly due to continuous thrust. This helps to improve on-site operation safety and reduce the risk of personnel injury. In addition, the intermittent impact of the striking block 92 can disintegrate the connection strength between the adhesive plate 2 and the rail 1 in stages, avoid local stress concentration, protect the rail 1 base material (reduce subsequent repair costs), and allow the adhesive plate 2 to fall off as a whole, reducing the amount of residual cleaning work.

[0043] Furthermore, during the process of driving the corresponding push plate 6, fixed box 7, and wedge-shaped cutter head 4 to move horizontally together by rotating the threaded rod 5, the push plate 6 will drive the corresponding push block 87 to move together, and the horizontal thrust generated by the movement of the push block 87 on the corresponding fixed cylinder 84 (such as...) Figure 6(As shown in the direction), the corresponding fixed cylinder 84, rotating gear 1 85, and rotating gear 2 86 can be driven to move together. This ensures that when the positions of the fixed box 7 and the wedge-shaped cutter head 4 are adjusted as required, rotating gear 1 85 and the corresponding spur gear 812 are always meshed. That is, it ensures that when the micro motor 81 starts running, it can always drive the striking block 92 to move and intermittently strike the corresponding wedge-shaped cutter head 4 through the cooperation of the corresponding rotating gear 1 85, spur gear 812, and striking component 9.

[0044] Reference Figures 4-16 Both cutting components 10 include a rotating shaft 101, and the rotating shaft 101 is rotatably mounted on the inner wall of the corresponding fixed box 7. Both rotating shafts 101 are equipped with cutting mechanisms and pushing components.

[0045] Both cutting mechanisms include a turntable 103, which is fixedly mounted on a corresponding rotating shaft 101. Ball bearings 106 are fixedly mounted on both rotating shafts 101. Positioning discs 107 are fixedly mounted on the outer rings of both ball bearings 106. Limiting grooves 108 are formed on both positioning discs 107. Connecting rods 109 are slidably mounted on both limiting grooves 108. Blades 1010 are fixedly mounted on both connecting rods 109. Sensing components are mounted on both connecting rods 109. Driving components are mounted on both rotating shafts 101.

[0046] Both sensing components include an arc-shaped groove 104, and the arc-shaped groove 104 is formed on the corresponding turntable 103. Two compression springs 105 are fixedly installed on each of the two arc-shaped grooves 104. A circular roller 1011 is fixedly installed on each of the two connecting rods 109, and one end of each of the two circular rollers 1011 is slidably installed on the corresponding arc-shaped groove 104.

[0047] Both drive components include an incomplete gear 102, which is fixedly mounted on the corresponding rotating shaft 101. Each of the two striking blocks 92 has a second rack 94 that meshes with the corresponding incomplete gear 102. Figure 12 As shown, during the reciprocating motion of the second rack 94 under force, the tooth blocks on the corresponding incomplete gear 102 are always engaged with the tooth blocks on the second rack 94.

[0048] Both of the pushing components include two limiting rods, and the two limiting rods are fixedly installed on the corresponding positioning disks 107. Two driving grooves 1012 are opened on both of the two rotating shafts 101. A ring 1013 is slidably installed through and between the two corresponding limiting rods. Two driving members 1014 are fixedly installed on the two rings 1013, and one end of each driving member 1014 is slidably installed on the corresponding driving groove 1012. Two push plates 1015 are fixedly installed on the two rings 1013.

[0049] The existing ball bearings 106 are all composed of an inner ring, an outer ring, and multiple balls, with the balls rolling between the inner and outer rings. The two rotating shafts 101 are fixedly connected to the inner rings of the corresponding ball bearings 106, and the two positioning discs 107 are fixedly connected to the outer rings of the corresponding ball bearings 106. When the rotating shaft 101 is subjected to force and drives the inner ring of the corresponding ball bearing 106 to rotate, the friction between the inner ring of the ball bearing 106 and the balls will cause the balls to roll on the raceway between the inner and outer rings of the corresponding ball bearing 106, thus converting the "sliding friction between the inner and outer rings" into "rolling friction between the balls and the raceway". This significantly reduces the friction between the rotating shaft 101 and the corresponding positioning disc 107, ensuring that when the rotating shaft 101 is subjected to force and rotates, it will not directly drive the corresponding positioning disc 107 to rotate as well.

[0050] When the aforementioned drive component 8 and striking component 9 cooperate, the driving striking block 92 moves back and forth (e.g., ...). Figure 11 , Figure 12 During the intermittent striking of the corresponding wedge-shaped cutter head 4 (as shown in the direction), the striking block 92 will drive the corresponding second rack 94 to move back and forth. The second rack 94 is subjected to force and moves back and forth, and the driving force applied to the corresponding incomplete gear 102 can drive the corresponding rotating shaft 101 to rotate back and forth through the corresponding incomplete gear 102.

[0051] The initial thrust required for the rotation of the corresponding roller 1011, connecting rod 109, blade 1010, and positioning disk 107 is set to be less than the spring preload of the corresponding two compression springs 105. That is, when the equipment starts to run, the rotating shaft 101 is driven by force to rotate the corresponding turntable 103 and the two compression springs 105. At this time, the thrust generated by the two compression springs 105 on the corresponding roller 1011 can push the roller 1011, the corresponding connecting rod 109, blade 1010, and positioning disk 107 to rotate back and forth together.

[0052] When the wedge-shaped cutter head 4 and the blade 1010 are subjected to force and adhere to the surface bonding interface of the corresponding adhesive plate 2, the connecting rod 109 drives the corresponding blade 1010 to continuously advance and reciprocate, which can achieve "pre-cutting" of the bonding interface between the corresponding adhesive plate 2 and the rail 1, gradually widening the tiny bonding gap between the adhesive plate 2 and the rail 1, and gradually transforming the tiny bonding gap between the adhesive plate 2 and the rail 1 into a "cutting channel that can accommodate the front end of the wedge-shaped cutter head 4", so as to avoid the difficulty of inserting the wedge-shaped cutter head 4 into the adhesive plate when the traditional wedge-shaped cutter head 4 is "hard-push" by impact force alone. The tiny adhesive gap between the wedge head 2 and the rail 1 causes the cutting edge of the wedge head 4 to slip, effectively reducing the problem of "difficult initial insertion" of the traditional wedge head 4. This helps to increase the breaking speed of the wedge head 4 on the corresponding adhesive plate 2. At the same time, during the reciprocating rotation of the blade 1010 under force, impurities on the surface of the adhesive plate 2 can be cleaned simultaneously. Furthermore, the shearing force generated by the rotation can directly cut the molecular bonds of the cured adhesive on the surface of the adhesive plate 2, transforming the "surface contact expansion resistance" of the traditional wedge head 4 into the "line contact shearing resistance" of the blade 1010, making the advancement of the wedge head 4 smoother.

[0053] Furthermore, when the rotating shaft 101 is subjected to force, it drives the corresponding roller 1011, connecting rod 109, positioning disk 107 and blade 1010 to rotate through the cooperation of the two corresponding compression springs 105. The positioning disk 107 will drive the corresponding ring 1013 and the two driving components 1014 to rotate together through the two limiting rods. That is, at this time, the driving component 1014 and the corresponding driving groove 1012 are in a state of synchronous rotation.

[0054] At the same time, combined Figure 9 and Figure 10 It can be seen that the diameter and number of teeth of the rotating gear 85 are much smaller than those of the corresponding spur gear 812. That is, the transmission ratio between the two (transmission ratio = spur gear 812 / rotating gear 85) is greater than 1, which is a reduction transmission. Therefore, when the equipment starts to run, the micro motor 81 drives the corresponding striking block 92 to reciprocate slowly through the corresponding rotating gear 85, spur gear 812 and the power transmission component. That is, at this time, the striking block 92 is subjected to intermittent force and the frequency of striking the corresponding wedge-shaped cutter head 4 is low. And because the wedge-shaped cutter head 4 starts to break the corresponding adhesive plate 2 Its advancement mainly requires breaking through the surface adhesive interface of the adhesive plate 2 (which often exhibits aging and embrittlement after long-term service, and its adhesive strength is lower than that of the deep dense adhesive layer). At this time, the forward movement resistance of the wedge-shaped cutter head 4 is relatively small. Based on this working condition, the single concentrated impact force generated by low-frequency tapping can be precisely applied to the weak point of the surface adhesive interface through the wedge-shaped cutter head 4, achieving effective breakthrough without relying on high-frequency impact. This avoids the dispersion of impact energy caused by high frequency and low force, and ensures the accuracy of the initial cut, forming an optimal match with the low resistance requirement of surface demolition.

[0055] When the wedge-shaped cutter head 4 and the blade 1010 continue to advance, breaking the corresponding adhesive plate 2, the adhesive layer at the pre-cutting contact area of ​​the blade 1010 may not be fully aged, the cured adhesive may be dense and clumped together, or the blade 1010 may have rust protrusions or oxide scale hard contact with the surface of the rail 1, resulting in increased rotational resistance of the blade 1010. Furthermore, when the corresponding blade 1010, connecting rod 109, roller 1011, and positioning plate 107 work together to continuously reciprocate the rotation of the two compression springs 105, the moving resistance generated is greater than the spring preload of the two compression springs 105. At this time, as the rotating shaft 101 is driven by the corresponding turntable 103 and the two compression springs 105 to continuously reciprocate, the corresponding roller 1011 will compress the compression spring 105 that is gradually approaching it (i.e., as...). Figure 13 In the direction shown, when the rotating shaft 101 is still driving the corresponding compression spring 105 to rotate clockwise, the stationary roller 1011 will compress the corresponding upper compression spring 105.

[0056] When the rotating shaft 101 is continuously rotated under force and cannot drive the corresponding roller 1011 to rotate through the cooperation of the two compression springs 105, the driving force applied to the roller 1011 by the groove wall of the corresponding arc-shaped groove 104 and the movement limit of the roller 1011 by the corresponding limiting groove 108 can drive the roller 1011 to drive the corresponding connecting rod 109 and the blade 1010 to gradually move to the left (in combination with...). Figure 8 and Figure 14 (As shown in the direction), so that the blade 1010 gradually retracts into the corresponding wedge-shaped cutter head 4. This can effectively prevent the blade 1010 from chipping or curling at the cutting edge when the rotational resistance of the blade 1010 exceeds the design threshold and the blade 1010 continues to be driven to rotate back and forth to cut the adhesive interface (especially for high-strength insulating adhesives, hard twisting can easily cause plastic deformation of the cutting edge), or the connecting rod 109 and other components connected to the blade 1010 from twisting or breaking (torque exceeding the torsional strength of the material). This helps to improve the service life of the blade 1010 and its connected components.

[0057] Meanwhile, when the rotating shaft 101 drives the corresponding turntable 103 to rotate continuously, and it is impossible to drive the corresponding positioning disk 107 and the two limiting rods, the ring 1013, and the two driving members 1014 on the positioning disk 107 to rotate together through the corresponding roller 1011, the driving force applied to the end ball of the corresponding driving member 1014 through the corresponding two driving grooves 1012 can drive the corresponding two driving members 1014 to move the corresponding ring 1013 downward (e.g. Figure 16 direction shown).

[0058] During the process of the ring 1013 being forced to move the corresponding push plate 1015 downward (in conjunction with...) Figure 15 and Figure 16(as shown in the direction), the downward driving force applied to the corresponding disk 810 by the push plate 1015 (and combined with) Figure 12 and Figure 15 It can be seen that because the reciprocating distance of the striking block 92 is short, that is, the striking block 92 cooperates with the driving component and the sensing component to drive the positioning disk 107 and the push plate 1015 to reciprocate with a small amplitude, while the overall arc length of the push plate 1015 is relatively long. This ensures that when the push plate 1015 is subjected to force and reciprocates, its part can always be in contact with the surface of the corresponding disk 810, that is, ensure that when the corresponding push plate 1015 is subjected to force and moves up and down, it can always cooperate with the driving disk 810 to move up and down together. It can drive the corresponding disk 810, cylinder 89, spur gear 812, and parallel shaft gear 813 to move down together, that is, as Figure 10 In the indicated direction, drive the corresponding disk 810, cylinder 89, spur gear 812, and parallel shaft gear 813 to move to the left until the parallel shaft gear 813 meshes with the corresponding rotating gear 86.

[0059] Combination Figure 9 and Figure 10 It can be seen that the diameter and number of teeth of the rotating gear 86 are much larger than those of the corresponding parallel shaft gear 813. Therefore, the transmission ratio between them (transmission ratio = parallel shaft gear 813 / rotating gear 86) is less than 1, indicating a speed-increasing transmission. Thus, when the spur gear 812 is subjected to force and moves to disengage from the corresponding rotating gear 85, and the parallel shaft gear 813 is subjected to force and moves to mesh with the corresponding rotating gear 86, the rotating shaft 82 drives the corresponding cylinder 89 to rotate through the engagement of the rotating gear 86 and the parallel shaft gear 813. This increases the rotational speed of the cylinder 89, which in turn increases the frequency of the cylinder 89 in conjunction with the power transmission component and the two spring telescopic rods 91, driving the corresponding striking block 92 to reciprocate left and right and strike the corresponding wedge-shaped cutter head 4. By increasing the striking frequency, the high-frequency impact energy can continuously apply a "fatigue-type" disintegration force to the high-resistance area through the corresponding wedge-shaped cutter head 4. This helps to avoid the wedge-shaped cutter head 4 from stopping due to sudden changes in resistance, and helps to ensure the efficiency of the continuous movement of the wedge-shaped cutter head 4 in breaking the adhesive plate 2, thus shortening the maintenance time of the track adhesive insulation head.

[0060] To further clarify, the aforementioned fixed connection should be interpreted broadly unless otherwise explicitly specified and limited. For example, it may be welding, gluing, or integral molding, or other conventional methods well known to those skilled in the art.

[0061] In this invention, when it is necessary to use this equipment to dismantle the adhesive plate 2 on the rail 1, the main body 3 of the equipment is first erected on the rail 1, and the left end of the main body 3 of the equipment is fixed to the rail 1 (e.g., Figure 1(as shown in the direction), and then by rotating the two threaded rods 5, the two wedge-shaped cutter heads 4 are brought into contact with the side of the rail 1. Then, through the hydraulic system on the main body of the equipment 3, the two wedge-shaped cutter heads 4 are driven to move to the right, gradually approaching the corresponding adhesive plate 2 (as shown in the direction). Figure 1 direction shown).

[0062] When the two wedge-shaped cutter heads 4 are about to contact the surface bonding interface of the corresponding adhesive plate 2 with the corresponding blades 1010, the two micro motors 81 are started. At this time, the operation of the micro motors 81, through cooperation with the corresponding rotating shaft 82, rotating gear 85, spur gear 812, cylinder 89 and force transmission components, drives the striking block 92 to move intermittently to strike the corresponding wedge-shaped cutter head 4. The instantaneous impact force generated by striking the wedge-shaped cutter head 4 can be superimposed on the instantaneous high-intensity forward force on the basis of the continuous hydraulic advancement of the wedge-shaped cutter head 4 of the equipment, concentrating the energy at the front end of the wedge-shaped cutter head 4, quickly breaking the bonding force between adhesive molecules or the rust and adhesion between the adhesive plate 2 and the rail 1, realizing the synergistic effect of "continuous advancement + instantaneous breakthrough", which can help to significantly reduce the forward movement resistance of the wedge-shaped cutter head 4 and increase the speed of breaking the adhesive plate 2 when the wedge-shaped cutter head 4 moves to the right.

[0063] At the same time, the striking block 92 moves back and forth under the force (such as...) Figure 12 During the process (in the direction shown), the bonding surface of the corresponding adhesive plate 2 can be "pre-cut" by the cooperation of the striking block 92 with the driving component and the cutting mechanism, which drives the blade 1010 to reciprocate and rotate, gradually widening the bonding gap between the adhesive plate 2 and the rail 1. This can help improve the smoothness of the wedge head 4 in advancing and inserting into the gap between the corresponding adhesive plate 2 and the rail 1, and improve the breaking efficiency of the wedge head 4 on the corresponding adhesive plate 2.

[0064] Meanwhile, when the rotational resistance of the blade 1010 increases, the blade 1010 can be automatically retracted into the corresponding wedge head 4 through the cooperation of the blade 1010 with the sensing component and the pushing component, thereby protecting the blade 1010 and increasing the striking frequency of the reciprocating movement of the striking block 92 on the corresponding wedge head 4. After the striking frequency is increased, the high-frequency impact energy can continuously apply a "fatigue-type" disintegration force to the high resistance area through the corresponding wedge head 4, which can help avoid the wedge head 4 from stopping due to sudden change in resistance. This helps to ensure the efficiency of the continuous movement of the wedge head 4 in breaking the adhesive plate 2 and shortens the maintenance time of the track adhesive insulation head.
