Abstract
Description
Technical Field
[0001] This utility model relates to the field of crane technology, and in particular to an insulated rail. Background Technology
[0002] Insulated cranes are used in non-ferrous metal electrolytic aluminum, magnesium, lead, copper and other smelting workshops. Because the equipment on the ground in the workshop carries current, in order to prevent the current from the live equipment from being transmitted to the crane and the factory building through the hoisted components during operation, endangering the life safety of the operator and the safety of the equipment connected to the factory building, the current standard stipulates that three insulation measures be set on the trolley: an insulation layer between the insulated hook assembly, the hoisting mechanism and the trolley frame, and an insulation layer between the trolley frame and the vehicle body, so as to meet the safety requirements.
[0003] With increasing emphasis on safety, higher requirements are being placed on the insulation of insulated cranes in some situations. Currently, crane rails still have the following shortcomings in use:
[0004] 1. Although the three insulation measures can ensure the safe operation of the insulated crane, if a conductive phenomenon occurs between the insulated crane and the track, it will endanger the personal safety of the workers near the track. At present, there is a lack of protective measures for insulation protection of the insulated crane track.
[0005] 2. Nowadays, the tracks are almost all fixed with bolts to the track and track pressure plate. The bolts are often set vertically. This means that during long-term use, the pressure generated by the crane's movement will cause the track to vibrate, which can easily lead to the bolts loosening, posing a certain safety hazard.
[0006] 3. During the installation of existing tracks, most of the bolts are exposed on both sides of the track, which greatly affects the daily cleaning and maintenance of the track;
[0007] Therefore, there is an urgent need for an insulated track that can overcome the above-mentioned shortcomings. Utility Model Content
[0008] To overcome the shortcomings of the prior art, this utility model discloses an insulated rail, which not only provides insulation protection for the rail on the basis of the original standard requirement of three insulations for the trolley, but also allows for a firm and stable limit installation of the rail, avoiding the problem of rail and bolt loosening caused by the pressure and vibration of the crane in the traditional way, and greatly ensuring the operational safety of the lifting equipment.
[0009] To achieve the above objectives, the present invention adopts the following technical solution:
[0010] The width of the mounting groove is adapted to the bottom width of the rail. An insulated rail includes a rail and an I-beam. The upper part of the I-beam has several limiting plates arranged in an orderly fashion along the axial direction of the I-beam and parallel to its flanges. Each limiting plate has a flange on both sides that abuts against the flanges of the I-beam. A limiting and fixing mechanism is detachably installed at the lower part of the flange, located below the flange of the I-beam, for connecting the limiting plates to the I-beam. The limiting and fixing mechanism includes a connecting groove, a connecting rod, and a clamping plate. The lower end face of the flange has a connecting groove, and the clamping plate is located below the flange of the I-beam and parallel to the flange of the I-beam. The wing plates are arranged in parallel. On the side of the clamping plate corresponding to the connecting groove, there is a connecting rod that is detachably connected to the connecting groove and used to horizontally limit and fix the clamping plate. An installation cavity is formed between the limiting plate and the wing plate of the I-beam. The upper surface of the limiting plate is provided with a through-hole that extends into the installation cavity. An insulating plate that matches the installation cavity is provided inside the installation cavity. An insulating seat that matches the through-hole and protrudes from the through-hole is provided on the upper part of the insulating plate. An installation groove for installing the rail is provided in the middle of the upper surface of the insulating seat. Rail pressure plates that can slide and adjust in opposite directions and are used to press and fix the rail are provided on both sides of the upper surface of the insulating seat.
[0011] Furthermore, the lower surface of the flange of the I-beam load-bearing beam is provided with mounting screw holes, and the clamping plate is provided with threaded through holes that correspond to and are adapted to the mounting screw holes. The corresponding threaded through holes and mounting screw holes are provided with connecting bolts.
[0012] Furthermore, the side of the connecting groove corresponding to the axial direction of the I-beam is an open structure. Several limiting protrusions are arranged in an orderly manner along the depth direction of the connecting groove on the two corresponding inner side walls of the connecting groove. Several limiting protrusions are arranged in an orderly manner along the axial direction of the connecting rod on both sides, and are interlocked with the limiting protrusions through the open side of the connecting groove.
[0013] Furthermore, a rubber pad is provided between the insulation plate and the rail.
[0014] Furthermore, the width of the mounting groove is adapted to the bottom width of the rail.
[0015] Furthermore, both sides of the upper surface of the insulating seat are provided with sliding grooves perpendicular to the rail. The side of the insulating seat is provided with a limiting screw hole A that penetrates the sliding groove. The lower part of the rail pressure plate is provided with a slider that slides with the sliding groove. The side of the slider is provided with a limiting screw hole B that matches the limiting screw hole A. The corresponding limiting screw holes A and B are provided with limiting bolts.
[0016] Furthermore, the inner walls on both sides of the slide are provided with inner folded edges, and the slider is provided with limiting grooves on both sides that are adapted to the inner folded edges and have open ends.
[0017] Furthermore, a rubber pressure head is provided at the end of the track pressure plate near the rail.
[0018] Compared with the prior art, the beneficial effects of this utility model are: by setting a limiting plate and connecting it to the lower part of the flange of the I-beam, the bolts are not exposed on both sides of the track during traditional track installation, which not only facilitates daily track cleaning, but also improves the aesthetics.
[0019] By installing insulating plates, insulating seats, and rubber pads, the rails can be insulated, effectively preventing electrical accidents.
[0020] By engaging the limiting protrusions on both sides of the connecting rod with the corresponding limiting protrusions on the inner walls of the connecting groove, the limiting plate and clamping plate can be used to clamp and limit the flange of the I-beam bearing beam. This not only effectively ensures the firm and stable installation of the track, but also effectively avoids the problem of the connecting bolts being easily loosened due to the pressure and vibration of the traditional track.
[0021] By placing the insulating plate inside the mounting cavity, not only can the installation of the insulating plate be guaranteed to be firm and stable, but the problems of cumbersome operation and easy loosening or rusting of traditional bolt connection are also avoided.
[0022] By setting a sliding track plate, it is not only easy to slide and adjust the track plate, but also the vertical positioning and fixing of the track plate can be achieved through the cooperation of the slider and the groove, avoiding the situation of the track plate loosening due to the vibration of the track under force in the traditional way.
[0023] This utility model not only provides insulation protection for the rails on the basis of the original standard requirement of three-stage insulation for the trolley, greatly improving the insulation level and the intrinsic insulation of the plant, and achieving a high-reliability insulation improvement for materials, but also enables a firm and stable limit installation of the rails, avoiding the problem of rail and bolt loosening caused by the pressure and vibration of the crane in the traditional way, thus greatly ensuring the operational safety of the lifting equipment.

In the description, it should be understood that if there are terms such as "upper", "lower", "front", "rear", "left", "right" indicating the orientation or positional relationship, they are only corresponding to the drawings of this utility model for the convenience of describing this utility model, and do not indicate or imply that the device or element referred to must have a specific orientation.
[0030] Please refer to the instruction manual appendix. Figure 1-4 This utility model provides a technical solution:
[0031] To achieve the above objectives, the present invention adopts the following technical solution:
[0032] Example 1: An insulated track includes a steel rail 1 and an I-beam 9. The upper part of the I-beam 9 is provided with several limiting plates 4 arranged in an orderly manner along the axial direction of the I-beam 9 and parallel to the flanges of the I-beam 9. Both sides of the limiting plates 4 are provided with folded edges 7 that are attached to the sides of the flanges of the I-beam 9. The lower part of the folded edges 7 is detachably installed with a limiting and fixing mechanism 8 located at the lower part of the flanges of the I-beam 9 and used to connect the limiting plates 4 and the I-beam 9.
[0033] Specifically, the limiting and fixing mechanism 8 includes a connecting groove 12, a connecting rod 16, and a clamping plate 17. The lower end face of the folded edge 7 is provided with a connecting groove 12. The side of the connecting groove 12 corresponding to the axial direction of the I-beam 9 is an open structure. Several limiting protrusions 13 are provided on the two corresponding inner side walls of the connecting groove 12, arranged in an orderly manner along the depth direction of the connecting groove 12. The clamping plate 17 is located below the flange of the I-beam 9 and is arranged parallel to the flange of the I-beam 9. The clamping plate 17 and the connecting groove On one side corresponding to 12, there is a connecting rod 16 that is adapted to the connecting groove 12. On both sides of the connecting rod 16, there are several limiting protrusions 15 that are arranged in an orderly manner along the axial direction of the connecting rod 16 and are interlocked with several limiting protrusions 13 through the opening on one side of the connecting groove 12. The lower surface of the flange of the I-beam bearing beam 9 is provided with mounting screw holes 14. The clamping plate 17 is provided with threaded through holes 18 that are adapted to the mounting screw holes 14. The corresponding threaded through holes 18 and mounting screw holes 14 are provided with connecting bolts 19.
[0034] A mounting cavity 11 is formed between the limiting plate 4 and the flange of the I-beam bearing beam 9. The upper surface of the limiting plate 4 is provided with a through-hole 10 that extends into the mounting cavity 11. An insulating plate 5 that is adapted to the mounting cavity 11 is provided inside the mounting cavity 11. An insulating seat 3 that is adapted to the through-hole 10 and protrudes from the through-hole 10 is provided on the upper part of the insulating seat 5. An mounting groove 20 for mounting the rail 1 is provided in the middle of the upper surface of the insulating seat 3. Rail pressure plates 2 that can slide and adjust in opposite directions and are used to press and fix the rail 1 are provided on both sides of the upper surface of the insulating seat 3.
[0035] During track installation, first place the insulating plate 5 under the limiting plate 4, with the insulating seat 3 on the upper part of the insulating plate 5 protruding through the opening 10. Then, place the insulating plate 5 and the limiting plate 4 on the upper part of the flange of the I-beam bearing beam 9, so that the folded edges 7 on both sides of the limiting plate 4 are attached to the two sides of the flange of the I-beam bearing beam 9. Then, attach the clamping plate 17 to the lower part of the flange of the I-beam bearing beam 9. The connecting rod 16 on one side of the clamping plate 17 slides into the connecting groove 12 from the opening on one side of the connecting groove 12. As the connecting rod 16 slides in, the limiting protrusions 15 on both sides of the connecting rod 16 and the two inner sides of the connecting groove 12... The limiting bosses 13 on the wall are staggered and interlocked, and the clamping plate 17 is connected to the flange of the I-beam bearing beam 9 by connecting bolts 19. By using the interlocking of the limiting protrusion 15 and the limiting bosses 13, it can be ensured that the clamping plate 17 is always attached to the lower part of the flange of the I-beam bearing beam 9, avoiding the traditional bolt fixing method and effectively preventing the limiting plate 4 from loosening due to the pressure and vibration of the crane. The fixing of the limiting plate 4 also ensures the fixing of the insulating plate 5. Finally, the rail 1 is installed into the mounting groove 20. After the rail pressure plate 2 is slid towards the rail 1 and fixed, the rail 1 is fixed by the rail pressure plate 2.
[0036] In Example 2, to further improve the insulation protection of the rail 1 and provide stress relief and buffering protection against vibration of the rail 1, a rubber pad 6 is provided between the insulation plate 5 and the rail 1. A rubber pressure head 27 is provided at the end of the rail pressure plate 2 near the rail 1. When all three insulations in the crane trolley are in an accident state, the fault is transmitted to the rail 1 through the equipment, and then to the insulation plate 5 through the rubber pressure head 27 in the rail pressure plate 2 (which can partially reduce conductivity). The fault is then further insulated by the rubber pad 6, thus blocking the leakage current that exists in the accident state and achieving highly reliable insulation.
[0037] In Example 3, to ensure the firm and stable installation of the rail 1, the width of the mounting groove 20 is adapted to the bottom width of the rail 1. The mounting groove 20 has an open structure on both sides corresponding to the axial direction of the I-beam 9. The upper surface of the insulating seat 3 has sliding grooves 22 perpendicular to the rail 1 on both sides. The inner walls of both sides of the sliding groove 22 have inner folded edges 21. The side of the insulating seat 3 has limiting screw holes A23 that penetrate the sliding groove 22. The lower part of the rail pressure plate 2 has a slider 25 that slides with the sliding groove 22. The slider 25 has a limit screw hole A23 on both sides. The inner folded edge 21 has a limiting groove 24 that is adapted to it and has an open structure at both ends. The slider 25 has a limiting screw hole B26 on its side that is adapted to the limiting screw hole A23. The corresponding limiting screw holes A23 and B26 are equipped with limiting bolts. By using the snap-fit limiting of the inner folded edge 21 and the limiting groove 24, the vibration of the track pressure plate 2 in the vertical direction can be effectively avoided, thereby ensuring that the track pressure plate 2 always presses and limits the rail 1. The limiting bolts are used to fix the track pressure plate 2, which can effectively prevent the displacement of the track pressure plate 2.
