Compared with a ballast track, the ballastless track avoids the splashing of the ballast, and has the advantages of good smoothness, good stability, long service life, good durability and less maintenance work.

Welded mesh is generally referred to as ribbed mesh. The steel bar mesh is also called welded steel bar mesh, mesh of steel bar, etc. The net piece is formed by respectively arranging longitudinal steel bars and transverse steel bars at certain intervals, forming right angles with each other and welding all cross points together.

Because the ballastless track is integrally cast by adopting materials such as concrete, asphalt mixture and the like, in order to ensure the structural strength of the ballastless track, a reinforcing mesh is adopted to improve the structural strength of the track during casting, and when a reinforcing welded mesh is produced and prepared, the traditional process is carried out by adopting a manual welding mode, so that the efficiency is low, and the rapid and batch production is difficult to realize. When resistance welding machinery is adopted to weld the reinforcing mesh, although transverse steel bars and longitudinal steel bars used for welding are straightened, straightening degree detection parts are lacked, and some transverse steel bars or longitudinal steel bars which are not thoroughly straightened are bent during welding, so that pseudo-soldering of the transverse steel bars and the longitudinal steel bars can be caused during resistance welding, and the pseudo-soldering spots can be subjected to off-soldering during subsequent use of the reinforcing mesh, so that the welding quality of the reinforcing mesh is influenced.

Second embodiment

In the process of welding the reinforcing mesh, the transverse reinforcing steel bars are generally coiled reinforcing steel bar coils, which are pulled open and straightened, and then are conveyed to the feeding rollers 211 of the transverse reinforcing steel bar feeding assembly 2, and a plurality of transverse reinforcing steel bars are generally simultaneously conveyed by the plurality of feeding rollers 211; the longitudinal bars are cut out in advance according to the size of the mesh reinforcement to be produced, and then straightened and placed in the feed caps 314 of the longitudinal bar feeding units 3, and the longitudinal bars of the feed grooves 314 finally fall onto the moving transverse bars and are transferred together between the upper welding part 410 and the lower welding part 416, and are welded by resistance welding through the upper welding part 410 and the lower welding part 416. However, in actual production, the transverse steel bars and the longitudinal steel bars which are primarily straightened still have certain bending, so that the transverse steel bars or the longitudinal steel bars at the bending parts can not be contacted, and the transverse steel bars and the longitudinal steel bars which are not contacted can not be normally welded in the normal welding process, so that the phenomenon of insufficient welding exists, the welding quality of the reinforcing mesh is reduced, and the subsequent normal use of the reinforcing mesh is influenced. In addition, in the above embodiment, after the longitudinal steel bar falls onto the transverse steel bar, the transverse steel bar drives the longitudinal steel bar to move forward to the welding position, and due to external vibration, the position of the longitudinal steel bar on the transverse steel bar is changed, so that the longitudinal steel bar and the transverse steel bar cannot be welded together normally, and the normal use of the steel bar mesh is finally affected. Therefore, based on the above embodiments, the present device is further improved to solve the above technical problems.

As shown in fig. 16, the sidewall of the material guiding cover 309 is provided with a magnetization component 324, and when the feeding groove 308 drives the longitudinal steel bar to pass through a position corresponding to the magnetization component 324, the magnetization component 324 can magnetize the longitudinal steel bar, so that the longitudinal steel bar has magnetism (the feeding groove 308 is made of non-ferromagnetic material, so as to prevent the magnetization component 324 from magnetizing and affecting the normal transmission of the longitudinal steel bar).

As shown in fig. 17, a set of magnetic sensors 325 is disposed on the side wall of the discharge chute 311 near the transverse steel bar feeding assembly 2, and the number of the magnetic sensors 325 is the same as and corresponds to the number of the feeding rollers 211, and each magnetic sensor 325 can measure the magnetic field intensity of the corresponding transverse steel bar passing through the discharge chute. Specifically, the magnetic force sensor 325 may employ a hall sensor. After the longitudinal reinforcement of pay-off recess 308 conveying is magnetized, on the horizontal reinforcing bar of below falls from blown down tank 311, because the longitudinal reinforcement of whereabouts has magnetism after being magnetized, longitudinal reinforcement can the magnetic adsorption on the horizontal reinforcing bar on the one hand, both are even as an organic whole, drive longitudinal reinforcement forward motion to the welding position in-process at horizontal reinforcing bar, can overcome external vibration and lead to the change of longitudinal reinforcement in horizontal reinforcing bar top position, longitudinal reinforcement and horizontal reinforcing bar dislocation lead to the rosin joint problem when avoiding follow-up welding, and then improve the welding quality of reinforcing bar net. On the other hand, after the magnetized longitudinal bars fall onto the transverse bars, each transverse bar connected to the longitudinal bar is magnetized, and the magnetic sensor 325 can measure the magnetic field intensity of the magnetized transverse bar. Normally, after the longitudinal bars and each of the transverse bars are magnetically attracted, the magnetic field strength of the corresponding transverse bar measured by each of the magnetic sensors 325 is substantially the same, each of the magnetic sensors 325 transmits the measured magnetic field strength to the controller, the controller compares the measured magnetic force values, when one or more of the magnetic force values is smaller than a normal value, it indicates that the corresponding transverse bar measured by the magnetic sensor 325 is not magnetically attracted to the magnetized longitudinal bar, it indicates that the transverse bar and/or the longitudinal bar are bent, so that the transverse bar and/or the longitudinal bar cannot be magnetically attracted together, the controller records the intersection point of the transverse bar and the longitudinal bar, when the transverse bar and the longitudinal bar that are not magnetically attracted together are transmitted to the welding position, the controller controls the normal magnetic attraction of the transverse bar and the longitudinal bar that are farthest from both sides of the intersection point to be welded together (which can be determined by the result of the measurement of the corresponding magnetic sensors 325) to weld the corresponding upper welding portion 410 and the lower welding portion 416 to preliminarily complete the preliminary connection and fixation of the longitudinal bar and the transverse bar, and then gradually approaches the intersection point to weld together, and weld the transverse bar and the longitudinal bar and/or the transverse bar to be attracted to be welded together. Adopt above-mentioned welding sequence, weld horizontal reinforcing bar and the vertical reinforcing bar that normal magnetism adsorbs the connection together earlier, can play the effect of connecting fixedly to horizontal reinforcing bar and vertical reinforcing bar, weld again at last and have the bending and do not have horizontal reinforcing bar and the vertical reinforcing bar that magnetism adsorbs the connection together, can not lead to the fact the influence to other welding departments. On the contrary, if all the transverse bars and the longitudinal bars are welded at the same time, the bent transverse bars and/or the longitudinal bars are pressed by the upper welding part 410 and the lower welding part 416 during welding, and the transverse bars and/or the longitudinal bars are moved, which affects the welding accuracy and causes a cold joint problem.

Therefore, through magnetization treatment of the longitudinal steel bars, the longitudinal steel bars can be made to adsorb the transverse steel bars, so that the longitudinal steel bars and the transverse steel bars can be stably conveyed to a welding position, welding accuracy is improved, welding quality is guaranteed, the magnetized longitudinal steel bars can be used for further magnetizing the transverse steel bars, whether the cross points of the longitudinal steel bars and the transverse steel bars are connected together or not can be judged through measuring the magnetic field intensity of the transverse steel bars, and when all cross points of the longitudinal steel bars and the transverse steel bars are connected together, normal welding can be realized; when the existing transverse steel bars and/or longitudinal steel bars are not connected together (namely the transverse steel bars and/or the longitudinal steel bars are bent), the welding sequence of the cross points is adopted to gradually weld and fasten other transverse steel bars and longitudinal steel bars which are normally connected together, and finally the bent transverse steel bars and/or the bent longitudinal steel bars are welded, so that the influence on other welding points when the bent transverse steel bars and/or the bent longitudinal steel bars are welded is prevented, the welding accuracy is further improved, the welding quality of the reinforcing mesh is improved, and the technical effect is remarkable.

Finally, it should be noted that: although the present invention has been described in detail with reference to the foregoing embodiments, it will be apparent to those skilled in the art that modifications may be made to the embodiments or portions thereof without departing from the spirit and scope of the invention.
