As shown in Figures 1 and 2, the normalizer 30 can perform on-line or off-line normalizing on the welded joint (not shown in the figure) on the rail 90, for example; it will be understood that the normalized The object, that is, the welded joint on the rail 90, the welding method used is not restrictive. However, the welded joint on the rail 90 generally has a large internal stress during welding and can be released during the normalizing process. The normalizing process used is not limited to the embodiment of the present invention. The normalizing machine 30 mainly includes a clamping and centering device 31 and an open-close induction coil device 37, and may also include a coil opening and closing and translation device 32, and may even include a transformer 33, an alignment operation part 391, a housing 39, and a hoist. One or more of frame 36, infrared thermometer 38, image sensor 35, etc. Among them, the above-mentioned or many other devices or components of the normalizer 30 can be directly or indirectly connected to the hanger 36, so that they can be transported as a whole through the hanger 36; the infrared thermometer 38 is used to monitor the corresponding temperature information; the housing 39 can be A number of devices or components are formed by a steel plate and basically surround the inside thereof, thereby forming a normalizer 30 that is generally box-shaped, for example, which is convenient for overall transportation.

Specifically, as shown in FIGS. 3 to 6, the hanger 36 can be formed by rigid connection of a high-strength steel structure (for example, formed by welding of steel profiles), which can form a larger internal space to accommodate many devices of the normalizer 30 Or components, such as the open-close induction coil device 37, the coil open-close and translation device 32, the transformer 33, etc., are beneficial to improve the overall structure and compactness of the normalizer 30. In an embodiment, the hanger 36 includes a frame-shaped frame body 368 and a frustum-shaped frame body 369 arranged on the frame-shaped frame body 368. The top of the frustum-shaped frame body 369 is provided with a frustum 3691, which can be used For installing the rotatable spreader 361, for example, the spreader 361 is fixedly installed on the frustum 3691 through two parallel pin shafts 363. The crane can be connected to the rotatable spreader 361 through a flexible chain tension member (such as a flexible chain), so that when the normalizing machine 30 is hoisted, especially when the welding joints to be normalized are aligned. , The operator can manually push the hoisted normalizer 30 to rotate to a predetermined position (in this case, the rotatable feature of the rotatable spreader 361 is used), which makes the operation more convenient.

The box-shaped frame body 368 may specifically be a square table frame structure, which can be fixedly connected and formed by a plurality of rigid beams, as shown in the example of FIG. 3, the rigid beam includes the top of the box-shaped frame body 368 which is arranged in parallel in the x direction. The two beams also include four beams arranged in parallel in the y-direction (the two beams are a group of beams arranged on the front and rear of the box-shaped frame body 368), and also include four beams arranged in parallel in the z-direction Four beams (two beams are a group and one group is arranged before and after the box-shaped frame body 368); the rigid beams arranged in the x direction can also be fixedly provided with corresponding load-bearing components to fix the inside of the normalizing machine 30 Components (for example, pressure device 33, infrared thermometer 38, etc.); the size of the box-shaped frame body 368 can be adjusted and designed by factors such as the size of the components contained in the box-shaped frame body 368. In one embodiment, as shown in FIGS. 3 to 8, the clamping and centering device 31 includes a rigid holder 301 and a pair of clamping arms 311 mounted on the rigid holder 301, and the pair of clamping arms 311 includes a front clamping The arm pair 311a and the rear clamping arm pair 311b are arranged substantially parallel to the front and rear. The front clamping arm pair 311a and the rear clamping arm pair 311b are respectively rotatably mounted on the rigid holder 301 in the front-rear direction, and the rigid holder 301 restricts the front clamping arm pair 311a and the rear clamping arm pair 311b in Displacement in the front and rear direction; in this way, the front clamping arm pair 311a and the rear clamping arm pair 311b on the rigid holder 301 can conveniently rotate in the yz plane to clamp the rail 90 or release the rail 90, and, The rigid cage 301 can resist or bear the internal stress released during the normalizing process, and the clamped rail 90 is not easy to deform during the normalizing process. The front clamping arm pair 311a can be arranged symmetrically with respect to the center plane 310 of the clamping and centering device 31, and the rear clamping arm pair 311b can be arranged symmetrically with respect to the center plane 310 of the clamping and centering device 31, which is beneficial to It is realized that the front clamping arm pair 311a and the rear clamping arm pair 311b clamp the rail 90 synchronously and are centered relative to the rail 90.

Continuing as shown in Figures 2, 5 and 6, the rigid cage 301 can form a cavity to form a substantially closed frame and is located substantially below the hanger 36. Specifically, the front clamping arm fixes the crossbeam 314a and the rear clamp The tight-arm fixed cross beam 314b, the left cross beam coupling shaft 315a, and the right cross beam coupling shaft 315b are fixedly connected to form a square (for example, rectangular) frame structure, thereby forming a rigid cage 301 according to an embodiment of the present invention; specifically, the left cross beam is connected Both ends of the shaft 315a and the right cross beam coupling shaft 315b have threads, and the threads at both ends can be partially extended out of the front clamping arm fixing beam 314a and the rear clamping arm fixing beam 314b, respectively, and are respectively passed through, for example, slotted nuts 3151 Realize a fixed connection. The front clamping arm fixing beam 314a or the rear clamping arm fixing beam 314b can be formed by, for example, a front steel plate and a rear steel plate. A limited hole 3142 is formed between the front steel plate and the rear steel plate. The arms of the clamping arm pair 311 can pass through the limit. The position hole 3142 passes through the limit hole 3142 to limit the position in the front-rear direction; specifically, each arm of the front clamping arm pair 311a is restricted front and rear in the limit hole 3142 of the front clamping arm fixing beam 314a and passes through a limit hole 3142. The clamping arm rotation pin 3141 is rotatably mounted on the front clamping arm fixing beam 314a, and each arm of the rear clamping arm pair 311b is restricted back and forth in the restriction hole 3142 of the rear clamping arm pair 311b and A clamping arm rotation pin 3141 is rotatably mounted on the rear clamping arm pair 311b, so that the front clamping arm pair 311a and the rear clamping arm pair 311b are respectively rotatably mounted on the rigid holder in the front-rear direction 301 on.

The rigid cage 301 can be a very stable frame structure. During the normalizing process, the rigid cage 301 can effectively resist or withstand the internal stress released by the welded joint when normalized, for example, even if it is subjected to very large The internal stress released by the welded joint will not be deformed; therefore, it can effectively prevent the clamped rail 90 from deforming due to the internal stress release of the welded joint being normalized during the normalizing process. It will be understood that the characteristics of the components of the rigid cage 301 can be selected based on the magnitude of the internal stress that the rigid cage 301 needs to effectively resist or bear, so as to ensure its rigidity.

As shown in Figure 7, the clamping and centering device 31 can be arranged symmetrically along its center plane 310; further, the clamping and centering device 31 can also be along the front clamping arm fixing beam 314a and the rear clamping arm fixing beam 314b. The center lines between the centers are arranged symmetrically back and forth. Therefore, it will be understood that the arrangement of the components of the front end of the clamping and centering device 31 shown in FIG. 7 is also applicable to the corresponding components of the back end.

As shown in FIGS. 3-24, the lower end of the box-shaped frame body 368 of the hanger 36 is provided with a plurality of pin holes 362 (for example, four pin holes 362). The pin holes 362 can be used to realize the hanger 36 and clamping The rigid holders 301 of the centering device 31 are fixedly connected together. For example, the clamping arm rotation pin 3141 can pass through the pin hole 362 so that the front clamping arm of the clamping centering device 31 can be fixed to the beam 314a or the rear clamping arm. The fixed cross beam 314b and the hanger fixing 36 are connected together. In this way, the clamping and centering device 31 and the hanger 36 can form a strong and stable body structure. It will be understood that the fixed connection between the hanger 36 and the rigid cage 301 is not limited to the above-mentioned embodiment. For example, it may also be fixedly connected with the rigid cage 301 by welding or the like, or even be integrated with the rigid cage 301. Forming; the lower end of the box-shaped frame body 368 of the hanger 36 is not limited to being fixed on the inner side of the front clamping arm fixing beam 314a or the rear clamping arm fixing beam 314b; the specific shape of the hanger 36 is not limited to the figure For the shape of the example, in other embodiments, when the whole normalizer 30 does not need to be moved by hoisting, the hanger 36 can also be deformed into a general internal body structure without a hanger, for example.

It will be understood that after the clamping and centering device 31 clamps the rail 90 back and forth, the clamping and centering device 31 or the rigid cage 301 provided therein can also realize the overall positioning of the normalizer 30 relative to the steel rail 90, and the rigid cage 301 The hanger 36 fixedly connected together is also positioned integrally therewith. The coil opening and closing and translation device 32 can perform local positioning operations such as welding seam alignment on the basis of the overall positioning. For example, the opening and closing induction coil device 37 can be aligned along the welding seam of the welding joint. The front-rear direction of the welded joint moves the induction coil device 37 parallel to the rail 90.

It should be understood that the rigid cage 301 formed by the fixed connection of the front clamping arm fixed cross beam 314a, the rear clamping arm fixed cross beam 314b, the left cross beam coupling shaft 315a and the right cross beam coupling shaft 315b can be enclosed together with the hanger 36 to form a larger The internal space can be used to arrange larger-sized coil opening and closing and translation device 32, induction coil device 37 and transformer 33, etc. (that is, coil opening and closing and translation device 32, induction coil device 37 and transformer 33 Etc. are arranged in the above-mentioned internal space), so that the overall internal structure layout is reasonable, and the overall structure appears compact, which is convenient for overall on-site transportation and transfer.

It also needs to be understood that this stable square frame structure not only makes the internal structure of the normalizing machine 30 reasonable and compact, but also has high structural strength. This structure is used as the carrier and reference for the normalizing machine 30. It can avoid the deformation of the rail welded joint under high temperature due to the internal stress release of the welded joint of the rail 90 during normalizing, which is conducive to the improvement of the quality and performance of the welded joint after normalizing. It is also beneficial to keep the distance between the induction coil 371 and the cross-sectional profile of the steel rail 90 enveloped by the induction coil 371 basically stable and consistent during the normalizing process, thereby improving the normalizing effect.

Specifically, each arm of the clamping arm pair 311 (for example, each arm of the front clamping arm pair 311a or the rear clamping arm pair 311b) is rotatably mounted on the clamping arm through a clamping arm rotation pin 3141. The arms are fixed to the cross beam 314, so that each arm can individually rotate around the clamping arm rotation pin 3141 during the clamping operation, for example, under the pushing of the clamping cylinder 312. In addition, the clamping arm pair 311 is arranged symmetrically with respect to the center plane 310 of the clamping and centering device 31, thereby facilitating synchronous clamping and centering between them; the normalized steel rail 90 has a symmetrical section. In the case of steel rails, the centering clamps 313 provided at the lower ends of the arms of the clamping arm pair 311 may also be arranged symmetrically with respect to the center plane 310 and have a symmetrical structure.

In one embodiment, as shown in FIGS. 7 and 8, corresponding to the front clamping arm pair 311a and the rear clamping arm pair 311b, a clamping cylinder 312 is respectively provided, and the clamping cylinder 312 is located on the front clamping arm pair 311a or The upper ends of the arms of the rear clamping arm pair 311b are arranged laterally, for example, the cylinder part and the piston rod of the clamping cylinder 312 are respectively connected to the top ends of the two arms of the front clamping arm pair 311a or the rear clamping arm pair 311b. Articulated, the clamping cylinder 312 is arranged substantially parallel to the y direction. The clamping cylinder 312 can drive the two arms of the clamping arm pair 311 to respectively rotate around the clamping arm rotation pin 3141 so that the centering clamp 313 clamps the rail 90; alternatively, multiple clamping cylinders 312 are the same (For example, having the same structure, the same type, and the same parameters), by providing multiple control components of the clamping cylinder 312, the clamping cylinder 312 can be controlled synchronously so that the rail 90 is clamped substantially synchronously, which is beneficial to the trend In order to drive multiple sets of clamping arm pairs 311 to act in unison, it is beneficial to improve the synchronization of clamping actions.

Further, the normalizer 30 not only has the function of clamping the rail 90 to be normalized, but also has the function of adaptively centering the rails 90 of different shapes; the clamping and centering device 31 can be used to achieve The above function is used to clamp the rail 90 together at the front and rear positions of the welded joint and center the rail 90 adaptively to the clamped rail 90.

It should be pointed out that the above-mentioned centering function realized by the clamping and centering device 31 of the normalizing machine 30 fully considers its service. The coil of the open-close induction coil device 37 needs to stably and uniformly envelop the requirements of the rail 90, and the clamping The tight steel rail 90 is a case of a welded integrated steel rail with a certain accuracy; self-aligning to the clamped rail 90 can realize the positioning of the normalizing machine 30 as a whole relative to the rail 90 currently to be normalized, especially The coil 3712 of the open-close induction coil device 37 can be positioned relative to the rail 90 through the centering, so that the open-close induction coil device 37 uses the rail 90 currently to be normalized as the positioning reference for induction heating, even if it is clamped. The rail 90 is different in terms of inclination, front and back batches, etc. The distance between the coil of the closed induction coil device 37 and the cross-sectional profile of the rail 90 can be better kept consistent; that is, the clamping and centering device 31 is already equipped with A certain precision welded connection integrated steel rail 90 is clamped and self-aligned with the steel rail 90 as a reference, so as to ensure the alignment accuracy of the normalizing machine 30 relative to the normalized steel rail 90, and ultimately ensure that the coil and The rail profile spacing remains stable and consistent. This clamping and centering method can lead to a good normalizing effect (for example, the induction heating temperature of the weld is uniform, and the normalizing effect of the welded joints of different batches of rail 90 is good and stable).

It should be understood that the centering operation performed by the clamping centering device 31 is to center itself relative to the rail 90 during the clamping process, rather than centering the rail 90 itself to other objects or other rails, for example, it It is completely different from the centering operation performed when welding two unconnected rails. In terms of specific differences, for example, during rail flash welding, the object of clamping and centering is two rails in different positions. The requirement of clamping and centering is to make the two rails in a straight line and the rails are aligned. The centering is performed with the welder’s own structure as a guarantee, and the cross-sections of the two rails are completely aligned; and due to the requirements of the welding process, it is necessary to apply a certain upsetting force to the two rails in the axial direction while clamping Only then can it be ensured that the welded joint meets the specified strength requirements; in addition, it is also required to facilitate the adjustment of the axial position between the two rails. Therefore, when steel rails are welded, not only is the clamping and centering device required to have a higher clamping force and upsetting force, but also the front and rear pairs of clamping devices must be relatively movable.

In one embodiment, considering the specific difference of the rail 90 being normalized, for example, the slight left-right tilt of the curved section of the rail, the centering clamp 313 has elastic support relative to the contact surface of the rail 90 when the rail 90 is clamped. Among them, the elastic support function can be specifically realized by an elastic element provided in the centering clamp 313 and the like. For example, as shown in FIG. 10, a corresponding elastic support component may be provided in each clamp body 3134 of the centering clamp 313, and the elastic support component is arranged relative to the lower jaw surface 913 of the rail head of the rail 90, so that the clamp The tight centering device 31 can center the rail 90 relatively clamped by the rail 90 adaptively along the center line 919 of the rail 90.

It should be noted that the elastic support element in the elastic support assembly is located between the centering clamp 313 and the lower jaw surface 913 of the rail 90. The elastic element can be compressed during the clamping process to rebound the centering clamp 313. The rebound force can achieve elastic support and slightly adjust the orientation of the clamping and centering device 31 relative to the rail 90, so as to achieve self-adaptive and accurate centering of the rail 90, and it is also beneficial for the induction coil 371 to close during the normalizing process, for example. Afterwards, the distance between the cross-sectional profile of the rail 90 and the surrounding rail 90 remains basically stable, and it is also beneficial to keep the distance between the induction coil 371 and the cross-sectional profile of the surrounding rail 90 basically stable and consistent after multiple centering, thereby improving normalization. effect.

FIG. 10 shows a partial structural schematic diagram of a specific embodiment of the centering clamp 313 when clamping and acting on the rail 90. As shown in Figures 7 and 10, the clamping and centering device 31 also includes a positioning block 316, which is fixedly installed on the lower surface of the clamping arm fixing beam 314 facing the rail 90, and the positioning block 316 is fixed on the rail 90. When clamped, it abuts against the rail head of the rail 90. The positioning block 316 can act together with the centering clamp 313 during the clamping and centering process to realize the positioning of the normalizer 30 relative to the clamped rail 90. In one embodiment, the positioning block 316 is detachably fixedly installed on the positioning base on the lower surface of the clamping arm fixing beam 314, so as to correspond to different types of rails 90, and different positioning blocks 316 can be designed and selected accordingly. The corresponding positioning block 316 is installed. Correspondingly, the clamp body 3134 of the centering clamp 313 can be designed to be detachably fixedly connected to the arms of the clamping arm pair 311, for example, detachably fixedly connected to the arms of the clamping arm pair 311 by bolts 3137. In this way, the clamp body 3134 can also be designed according to different types or models of steel rails 90, and the corresponding clamp body 3134 can be selected and installed according to the different steel rails 90 clamped. Therefore, the normalizer 30 can be applied to more rail types (for example, "I"-shaped rails, channel-shaped rails) and normalize them.

Taking the contact surface of the centering clamp 313 with respect to the rail 90 when the rail 90 is clamped, including the rail head lower jaw surface 913 and the rail waist side surface 912 as an example, the elastic support component on the clamp body 3134 of the centering clamp 313 has an arc The support body 3131 (such as a steel ball) and the elastic element 3132 with a shaped contact surface; the left and right clamp bodies 3134 can be detachably fixedly installed on the left and right arms of the clamping arm pair 311 through bolts 3137, etc., respectively. The clamp body 3134 is provided with a positioning groove 3135 that opens toward the lower jaw surface 913 of the rail head of the rail 90. For example, the opening direction of the positioning groove 3135 is substantially perpendicular to the lower jaw surface 913 of the rail head; the elastic element 3132 and the support body 3131 can go from bottom to top. They are placed in the positioning groove 3135 one by one. The positioning groove 3135 can be filled with corresponding lubricating grease, and then the gap between the support body 3131 and the positioning groove 3135 is covered by the cover plate 3133. The cover plate 3133 can cover the support body The 3131 and the elastic element 3132 are limited in the positioning groove 3135. The elastic element 3132 can be specifically, but not limited to, a disc spring. The support body 3131 is used to contact the rail 90, which can be made of various rigid materials; the shape of the clamping surface of the clamp body 3134 can be based on the rail of the rail 90 that it contacts. The shape of the waist side 912 is specifically designed.

For example, when the clamping cylinder 312 drives the clamping arm pair 311 to clamp the rail 90, the clamp body 3134 rigidly contacts the rail waist side surface 912 of the rail 90 and rigidly clamps the rail waist, aligning the support in the clamp 313 The arc-shaped contact surface of the body 3131 will contact the lower jaw surface 913 of the rail head and form elastic contact with it. The support body 3131 of the elastic support assembly can apply a pre-tightening force to the lower jaw surface 913 of the rail head. As the pre-tightening force increases, the pre-tightening The z-direction component of the force can push the rail head tread 911 of the rail 90 against the positioning block 316, and the positioning blocks 316 of the front clamping arm fixing beam 314a and the rear clamping arm fixing beam 314b will all be based on the rail head tread 911 It is compressed and positioned on the rail head tread 911, that is, the clamping and centering device 31 will be able to perform the centering operation based on the rail head tread 911; at the same time, the elastic element 3132 (such as a disc spring) will be compressed to produce a function The force on the clamp body 3134 (for example, its component in the y direction) can cause the centering clamp 313 during the clamping process to be centered along the center line 919 of the rail 90 with the rail head tread 911 as a reference.

Therefore, the introduction of the positioning block 316, the support body 3131 and the elastic element 3132 can make the centering clamp 313 self-adapt to the rail head tread 911 during the clamping process for automatic centering without considering the induction normalizing device 30. Whether additional adjustments should be made to the rail head tread 911 of the rail 90 in the curve range due to the left and right inclination of the curve; thus, regardless of whether the rail 90 is in a straight section or a curve section, the centering clamp 313 is clamping During the process, it can perform self-adaptive centering basically along the centerline 919 of the clamped rail 90, and at the same time, it is helpful to ensure that the distance between the induction coil 371 of the induction coil device 37 and the cross-sectional profile of the enclosed rail 90 is basically stable and consistent. For example, when multiple welded joints of the same steel rail 90 are normalized multiple times, the alignment is based on the same steel rail 90, and the centering effect is good, so that the induction coil 371 is stable and consistent with respect to the rail 90 enveloped by it. , Which is beneficial to improve the uniformity of the induction heating effect during the normalizing process or multiple normalizing processes.

It should be noted that when the model or structure of the rail 90 acting on the centering clamp 313 is changed, the corresponding structure of the centering clamp 313 can be changed accordingly, such as changing the shape of the clamp body 3134. , The orientation of the positioning groove 3135 on the clamp body 3134, etc. When normalizing the welded joints of rails 90 of different models or structures, corresponding positioning blocks 316 and centering clamps 313 can be replaced and installed.

In order to further improve the clamping synchronization of the centering clamp 313, a corresponding synchronous clamping assembly is provided for each clamping arm pair 311. The synchronous clamping assembly is used to make the front clamping arm pair 311a or the rear clamping arm The left arm and the right arm of 311b are basically clamped in left and right synchronously, so that the rail 90 is clamped in left and right synchronously.

In an embodiment, as shown in FIGS. 7-9, the synchronous clamping assembly mainly includes a guide post 317 corresponding to each clamping arm pair 311, a synchronous slider 319, a left connecting plate 318a, and a right connecting plate 318b. The guide post 317 is fixed on the upper surface of the middle of the clamping arm fixing beam 314 along the center plane 310 of the clamping and centering device 31, which can be cylindrical, for example; as shown in Figures 8 and 9, the guide post 317 can pass The threaded connection is fixedly mounted on the fixed mounting seat 3171 of the clamping arm fixed crossbeam 314. The fixed mounting seat 3171 provides an installation reference for installing the synchronous clamping assembly; the synchronous slider 319 is provided with a hole corresponding to the guide post 317, thereby The synchronization slider 319 can be sleeved on the guide post 317 and can slide linearly along the center plane 310; the left connecting plate 318a is used to connect the left end of the synchronization slider 319 to the left arm of the clamping arm pair 311, and the right connecting plate 318b is used To connect the right end of the synchronous slider 319 to the right arm of the clamping arm pair 311, the synchronous slider 319 can be hinged to the left connecting plate 318a and the right connecting plate 318b respectively through the first connecting plate pin 3181, and the left connecting plate The 318a and the right connecting plate 318b can be respectively hinged with the left arm and the right arm of the clamping arm pair 311 through the second connecting plate pin 3182 (for example, hinged on the hinge mounting seat of the left arm or the right arm). The synchronization slider 319, the left connecting plate 318a, and the right connecting plate 318b in the synchronization clamping assembly are located between the left arm and the right arm of the clamping arm pair 311, and the synchronization slider 319 is designed symmetrically with respect to the center plane 310. The left connecting plate 318a and the right connecting plate 318b are also arranged symmetrically with respect to the center plane 310; in this way, during the working process of the synchronous clamping assembly, the left and right synchronous actions can work, which can ensure that the synchronous slider 319 is linearly positioned on the guide post 317 Sliding and not sticking easily.

When the clamping cylinder 312 drives the clamping arm pair 311 to clamp the rail 90, the left and right arms of the front clamping arm pair 311a or the rear clamping arm pair 311b respectively rotate around the clamping arm rotation pin 3141, synchronously The slider 319 will be able to move straight down along the guide post 317 under the simultaneous rotation of the two arms; if the left arm and the right arm of the clamping arm pair 311 temporarily rotate out of sync, it will cause the arm that rotates too fast One end of the synchronous slider 319 corresponding to one end drops too fast, and the end of the arm that rotates too slowly corresponds to the end of the synchronous slider 319 drops too slowly, the synchronous slider 319 will tilt and become temporarily stuck. At this time, clamp the cylinder 312 will automatically drive the arm that rotates too slowly to continue to rotate until the inclination of the synchronization slider 319 basically disappears, the left arm and the right arm of the clamping arm pair 311 will continue to rotate synchronously and drive the synchronization slider 319 to continue to move linearly downward. Therefore, the synchronous clamping assembly of the above embodiment can ensure that the left arm and the right arm of the clamping arm pair 311 basically perform the clamping actions synchronously during clamping. In addition, the introduction of synchronous clamping components, especially the guide post 317, can prevent the left and right arms of the clamping arm pair 311, and the clamping cylinder 312 from swinging too much left and right relative to the clamping arm fixed beam 314 (because the clamping arm pair The quadrilateral structure formed between the left arm and the right arm of 311, the clamping cylinder 312 and the clamping arm fixing beam 314 is not a fixed frame).

In one embodiment, as shown in FIGS. 2 and 5, the normalizing machine 30 is provided with a transformer 33 inside, which, for example, transforms the voltage output by the generator set 12, so as to provide corresponding power to the induction coil device 37 . The output end of the transformer 33 may be electrically connected to the working voltage access part 331 provided corresponding to the coil 3712, and the transformer 33 may be arranged in an internal space surrounded by the rigid holder 301 and the hanger 36.

In one embodiment, as shown in FIGS. 11 to 13, the coil opening and closing and translation device 32 can be based on the positioning provided by the clamping and centering device 31 (for example, on the positioning reference provided by the clamping and centering device 31). ) Relative to the clamping and centering device 31 or the rail 90 in the x-direction, the coil opening and closing and translation device 32 can drive the induction coil device 37 attached to it to open and close on the one hand, and on the other hand, it can also move in the x direction. Moving the induction coil device 37 parallel to the rail 90 in the front-rear direction to more accurately align the weld seam of the welded joint on the rail 90 is very helpful to improve the normalizing effect.

The coil opening and closing and translation device 32 may specifically include a coil installation positioning beam 322, a coil translation guide 327, a coil translation cylinder 3211, and a coil opening and closing cylinder 324 including a left coil opening and closing cylinder 324a and a right coil opening and closing cylinder 324b. The induction coil device 37 installed on the coil installation positioning beam 322 may be located in the cavity enclosed by the rigid holder 301 and between the front clamping arm pair 311a and the rear clamping arm pair 311b.

Wherein, the coil installation positioning beam 322 is hingedly connected to the induction coil device 37, that is, the induction coil device 37 is hingedly connected to the coil installation positioning beam 322, for example, the left coil support plate 373a and the right coil of the induction heating coil device 37 The pallet 373b is respectively provided with a left hoisting plate 3731a and a right hoisting plate 3731b, and the lower ends of the left hoisting plate 3731a and the right hoisting plate 3731b are respectively detachably fixedly connected to the upper ends of the left coil holding plate 373a and the right coil holding plate 373b ( For example, bolt connection), the upper ends of the left hoisting plate 3731a and the right hoisting plate 3731b are respectively provided with installation positioning holes, so that the upper ends of the left hoisting plate 3731a and the right hoisting plate 3731b can be hinged to the coil installation positioning beam 322 through, for example, a pin 3221. . In this way, the induction heating coil device 37 can be hoisted on the coil installation positioning beam 322 through the left hoisting plate 3731a and the right hoisting plate 3731b and the pin 3221. The induction heating coil device 37 is installed or hoisted on the coil installation positioning beam 322 and can be Along with the coil installation positioning beam 322, the coil installation positioning beam coil installation positioning beam coil installation positioning beam coil installation positioning beam coil installation positioning beam is moved forward and backward.

As shown in Figure 12, when the induction heating coil device 37 is in the closed state, both the left hoisting plate 3731a and the right hoisting plate 3731b are arranged in a "eight" shape so that the left coil support plate of the induction heating coil device 37 in the closed state Both the 373a and the right coil support plate 373b are substantially parallel (for example, parallel in the z direction). In this way, it is also beneficial to make the coil opening and closing and translation device 32 more compact in the vertical direction, and the upper left conductive block 3711a and the upper right conductive block 3711b and the transformer conductive bar 331 can more naturally achieve surface bonding.

As shown in Figures 11 and 29, the coil opening and closing cylinder 324 can drive the coil of the induction heating coil device 37 to open and close. The coil opening and closing cylinder 324 can be installed between the coil installation positioning beam 322 and the induction heating coil device 37. , Corresponding to the left half of the induction heating coil device 37 is provided with a left coil opening and closing cylinder 324a, and corresponding to the right half of the induction heating coil device 37 is provided with a right coil opening and closing cylinder 324b. Specifically, the rear cylinder head of the left coil opening and closing cylinder 324a is hinged to the left end of the coil mounting positioning beam 322 through, for example, a pin 3241, and the piston rod head of the left coil opening and closing cylinder 324a is detachably hinged to the induction heating through a pin 3242. On the left coil support plate 373a of the coil device 37; the rear cylinder head of the right coil opening and closing cylinder 324b is hinged to the right end of the coil mounting positioning beam 322 through, for example, a pin 3241, and the piston rod head of the right coil opening and closing cylinder 324b passes through a pin 3242 It is detachably hinged to the right coil support plate 373b of the induction heating coil device 37. By controlling the left coil opening and closing cylinder 324a and the right coil opening and closing cylinder 324b to expand and contract, the left half and the right half of the induction heating coil device 37 can be driven to rotate around the pin 3221 respectively, so that the induction heating coil device can be conveniently controlled 37 The positioning beam 322 is installed relative to the coil to open and close independently.

During use, the coil opening and closing and translation device 32 controls the extension of the piston rod heads of the left coil opening and closing cylinder 324a and the right coil opening and closing cylinder 324b, and the left coil support plate 373a and the right coil support plate 373b rotate toward each other, The lower conductive blocks 3713 of the induction heating coil device 37 are closely attached to each other, and the upper conductive block 3711 is attached to the working voltage access portion 331 (such as a transformer conductive bar); in this way, the induction heating coil device 37 and the transformer 33 form A closed loop, the induction magnetic field can be formed to heat the rail 90 after energization; on the contrary, after the normalizing process, for example, the left coil opening and closing cylinder 324a and the right coil opening and closing cylinder 324b are controlled to retract the piston rod head, and the left coil support plate 373a and the right coil support plate 373b are reset, and the induction heating coil device 37 is restored to the open state.

As shown in Figures 5 and 23, the coil translation guide 327 is fixedly arranged in the front and rear. For example, two coil translation guides 327 arranged in parallel left and right are fixed and arranged on the cross beam of the hanger 36 in the x direction, so that the coil translation guide 327 The positioning provided by the clamping and centering device 31 or the rigid cage 301 after the rail 90 is clamped back and forth is achieved. In this way, after the clamping and centering device 31 has clamped and centered the rail 90, it is fixedly installed on the crane. The positioning of the coil translation guide 327 on the frame 36 is determined. The coil opening and closing and translation device 32 also includes one or more coil translation sliders 328 arranged corresponding to the coil installation positioning beam 322, and one or more coil translation sliders 328 on each coil translation guide 327 can move along the coil translation guide 327 Sliding linearly in the front and rear directions, the coil installation positioning beam 322 is connected to the coil translation slider 328 through the slider connecting plate 3281, so that the coil translation guide 327 can linearly slide and slide along the coil translation guide 327. It should be noted that the arrangement of the coil installation and positioning beam 322 relative to the coil translational guide 327 is not limited to the above embodiment or the illustrated embodiment. In other alternative embodiments, the coil translational guide 327 is located above the coil installation and positioning beam 322 The coil installation positioning beam 322 can be slidably suspended on the coil installation positioning beam 322 through the coil translation slider 328; the coil installation positioning beam 322 can also be slidably seated on the coil translation guide rail through a sliding seat arranged on its bottom surface 327 is slid on, or slidably suspended on the coil translation rail 327 through a sliding seat arranged on its top surface, thereby eliminating the slider connecting plate, etc.; the number of the coil translation rail 327 is not limited to two, for example, It can be 1 or 3; the coil translation sliders 328 on each coil translation guide 327 can be arranged in pairs, and the pair of coil translation guides 327 can be connected together by the slider connecting plate 3281. In this way, the coil is installed with the positioning beam The translation stability of 322 is better. Of course, the number of coil translation sliders 328 provided on each coil translation guide 327 can also be other numbers (for example, 1 or 3).

Among them, the coil translation cylinder 3211 can be used to drive the coil installation positioning beam 322 to move linearly in the front and rear directions along the coil translation guide 327; specifically, the coil translation cylinder 3211 can be arranged along the x direction, and the coil translation cylinder 3221 can include a cylinder part. And the piston rod, the cylinder part is hinged on the hinge seat 364 of the hanger 36, the piston rod head is connected to the coil mounting positioning beam 322, and the piston end of the coil translation cylinder 3211 can push the coil mounting positioning beam 322 to move in the x direction. The hinged fixing of the cylinder body allows the coil translation cylinder 3211 to swing relative to the hanger 36 during operation, so as to avoid damage to the cylinder body and/or the piston rod in which the piston moves.

It will be understood that the coil opening and closing cylinder 324 can be arranged independently of the coil translation cylinder 3211, and they can be controlled independently of each other, so that the coil's translational movement in the x direction and the opening and closing actions in the yz plane can be independently controlled.

Specifically, during use of the coil opening and closing and translation device 32, after the rail 90 is clamped before and after the clamping and centering device 31, the clamping and centering device 31 or the rigid holder 301 provided therein provides the normalizing machine 30 In the case of the overall positioning relative to the rail 90, the coil translation cylinder 3211 can be controlled first to push the coil installation positioning beam 322 to slide in the x direction, so that the coil opening and closing and translation device 32 can perform, for example, welding under the overall positioning. The local positioning operation or the secondary positioning operation of the alignment allows the induction coil device 37 to more accurately align the weld seam of the welded joint to be normalized. At this time, the coil can be installed with the positioning beam 322 to prevent it from continuing to Slide in the x direction; then, control the left coil opening and closing oil cylinder 324a and the right coil opening and closing oil cylinder 324b to expand and contract, so that the lower conductive block 3713 of the induction coil device 37 closely fits, the upper conductive block 3711 and the working voltage access part 331 (For example, the conductive bars of the transformer) are attached to each other, so that the induction coil device 37 and the transformer 33 form a closed loop, and an induction magnetic field is formed to heat the rail 90 after being energized. Therefore, the coil opening and closing and translation device 32 can achieve accurate positioning in the x direction through local positioning operations or secondary positioning operations, and the secondary positioning operation is simple, and there is no need to consider induction during the clamping and centering process. The positioning of the coil device 37 relative to the weld seam; and the positioning operation of the induction coil device 37 relative to the weld seam and the opening and closing operations of the induction coil device 37 can be relatively independent, and the two do not affect each other, making the control more convenient and also beneficial to induction The positioning of the coil device 37 relative to the welding seam is more accurate.

12 and 14, the induction coil device 37 mainly includes an induction coil assembly 371, and also includes a conductive joint and a coil 3712, wherein the conductive joint is fixedly connected to the coil 3712 and electrically connected, and when closed, the conductive The joint part can be joined with the working voltage access part 331, and the induction coil device 37 and the transformer 33 form a closed loop. Of course, some conductive joint parts can also be joined to each other to conduct conduction to form a closed loop. In order to achieve adaptive bonding between the conductive joints and/or between the conductive joints and the voltage access part 331, the induction coil device 37 further includes a coil support plate 373 and an elastic support provided corresponding to the conductive joints. The elastic support portion 374 is located between the coil support plate 373 and the conductive block. The elastic support part 374 can provide elastic support for the conductive joint part and can be elastically deformed. Therefore, after the conductive joint part starts pre-contact during the coil closing operation, the conductive joint part can use the elastic support part 374 to adjust the conductive joint part and the connected part. For example, the bonding effect of the conductive bar of the transformer, the conductive joint can adapt to the surface to be joined to adjust the tightness of the joint, which not only helps to improve the normalizing efficiency, but also reduces the wear of the conductive joint after multiple closing operations.

In an embodiment, the conductive joint is specifically a conductive block, which includes an upper conductive block 3711 and a lower conductive block 3713. The upper and lower ends of the coil 3712 are respectively connected to the upper conductive block 3711 and the lower conductive block 3713. For example, the coil 3712 includes the left The induction coil 371a and the right induction coil 371b correspond to the upper left conductive block 3711a of the left induction coil 371a and the upper right conductive block 3711b of the right induction coil 371b respectively provided with a left elastic support portion 374a and a right elastic support portion 374b. Wherein, an elastic support part 374 may be provided between the coil support plate 373 and at least one of the upper conductive block 3711 and the lower conductive block 3713; for example, if the upper left conductive block 3711a and the upper right conductive block 3711b are connected to the working voltage when the coil is closed The connecting part 331 (for example, the conductive bar of a transformer) is attached to connect the high-voltage working voltage. The left elastic support part 374a and the right elastic support part 374b can be provided corresponding to the upper left conductive block 3711a and the upper right conductive block 3711b, respectively, so that the upper left conductive block is electrically conductive. The block 3711a and the upper right conductive block 3711b are each adaptively attached to the working voltage access part 331; if the coil is closed through the lower left conductive block 3713a and the lower right conductive block 3713b and the working voltage access part 331 (such as the transformer conductive row ) To connect to the high voltage working voltage (not shown in Figure 14), or corresponding to the lower left conductive block 3713a and the lower right conductive block 3713b are provided with a left elastic support portion 374a and a right elastic support portion 374b, so that the upper left The conductive block 3711a and the upper right conductive block 3711b are each adaptively attached to the working voltage access portion 331.

It should be noted that in order to make the conductive blocks directly bonded to each other better fit, the conductive blocks directly bonded to each other (for example, the lower left conductive block 3713a and the lower right conductive block 3713b as shown in FIG. 14) can also be provided with elastic supports部374.

The elastic support portion 374 may specifically, but is not limited to, a spring, one end of which may be seated on the coil support plate 373, and the other end may be fixedly connected to the conductive joint. The induction coil 371 can be specifically, but not limited to, a copper coil. The copper coil can be made of a hollow copper tube with cooling water circulating through it, thereby improving the cooling effect of the induction coil.

In one embodiment, as shown in FIG. 14, the induction coil device 37 further includes an insulating pad 372 disposed between the coil support plate 373 and the conductive joint, thereby preventing the combined induction coil from conducting electricity with the external structure. For example, an insulating pad 372 is arranged between the left elastic support portion 374a and the left coil support plate 373a, an insulating pad 372 is arranged between the right elastic support portion 374b and the right coil support plate 373b, and the left elastic support portion 374a and the left coil support plate 373a are arranged between the left elastic support portion 374a and the left coil support plate 373a. An insulating pad 372 is provided between the right elastic support portion 374b and the right coil support plate 373b. The lower left conductive block 3713a of the left induction coil 371a and the lower right conductive block 3713b of the right induction coil 371b pass through the insulating pad 372, respectively. It is rigidly connected to the left coil support plate 373a and the right coil support plate 373b.

In the induction coil device 37 of the embodiment shown in FIG. 14, when the coils are joined, the lower conductive blocks 3713 are attached to each other, and the upper conductive block 3711 and the transformer conductive bar 331 are connected through the elastic support portion 374. The self-adaptive fit can not only improve the normalizing efficiency, but also reduce the wear of the conductive block 3711 on the coil and the conductive bar 331 of the transformer during use, and increase the life of the induction coil device 37.

The image information collected by the image sensor 35 may be transmitted to the alignment operation unit 391 for display. The image sensor 35 may be specifically installed on the hanger 36, and by specifically arranging its position, the image sensor 35 can image the area including the welded joint.

Continuing as shown in FIGS. 1 and 2, the alignment operation part 391 may be provided on the top of the normalizing machine 30, which is convenient for the operator to view and operate. The alignment operation unit 391 has a function for displaying the relative position sensed by the image sensor 35, and controls the coil opening and closing and translation device 32 based on the displayed relative position to perform alignment operations of the induction coil device 37 with respect to the welded joint of the rail 90.

Command input, for example, related commands for controlling the opening and closing of the coil and the coil translation cylinder 3211 of the translation device 32. In the process of aligning the weld of the welded joint, the alignment operation part 391 can fine-adjust the position of the induction coil device 37 relative to the welded joint of the steel rail 90 according to the real-time displayed image information, so as to achieve accurate alignment. It will be understood that the specific implementation manner of the alignment operation portion 391 is not limited to the embodiment of the present invention, and the manner in which it controls the coil translation cylinder 3211 is also not restrictive; the alignment operation portion 391 may also implement other control functions, for example, The opening and closing of the induction coil device 37 is controlled by the control coil opening and closing cylinder 324.

It should be noted that the normalizing machine 30 of the above embodiment can be connected to a hydraulic pump station in the rail field normalizing operation system through a pipeline, so as to provide hydraulic power for many oil cylinders provided in the normalizing machine 30.
