Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of train track maintenance, in particular to a lithium battery type track grinding vehicle transfer device and a transfer method. BACKGROUND

[0002] With the rapid development of railways, the increase in the density of railway traffic, and the increasing time of track operation, rails need to be regularly maintained to ensure their normal service. Currently, grinding wheels and milling cutters are mainly used as tools for rail grinding. Due to the limitations of the performance of the grinding tools and the grinding method, manual grinding operation is low in efficiency and high in cost, and has been unable to meet the needs of rail grinding. Therefore, lithium battery type grinding vehicles with higher efficiency have emerged.

[0003] For some lithium battery type track grinding vehicles, their own volume is large and they are easy to be damaged. However, in some special projects, due to the lack of space and strict time requirements, the rail grinding vehicle needs to be transported from elsewhere to the work site. If manual handling is used for long-distance transportation of the rail grinding vehicle, the rail grinding vehicle needs to be disassembled, which may cause unnecessary damage to the rail grinding vehicle and increase the difficulty of work. Currently, long-distance transportation of the rail grinding vehicle is often carried out by using hoisting equipment and container system loading.

[0004] The inventor finds that this transfer method using hoisting equipment and container system loading requires a large amount of manual cooperation and coordination of hoisting equipment and other instruments, resulting in long transportation time, high cost, and the power supply of the grinding vehicle cannot be conveniently supplemented during the transfer process. SUMMARY

[0005] To solve the problems of the need for a large amount of manual cooperation, long transportation time, and high cost in the transfer process of the existing rail grinding vehicle, the present application provides a lithium battery type track grinding vehicle transfer device, which can improve the efficiency of hoisting the grinding vehicle.

[0008] By the above scheme, the lithium battery rail grinding vehicle can be moved from the warehouse to the vehicle cabin and moved out of the vehicle cabin, realizing the transfer of the lithium battery rail grinding vehicle between the warehouse and the work site. During the transfer process, only the operator needs to operate the device and simply assist the hooking of the lithium battery rail grinding vehicle hoisting point, without the coordination and scheduling of multiple equipment machines such as cranes, saving manpower, time and cost.

[0016] Further improvement, further comprising a charging device installed in the vehicle cabin for charging the lithium battery rail grinding vehicle to meet the charging needs of the lithium battery rail grinding vehicle.

[0017] The second aspect of the present application provides a lithium battery rail grinding vehicle transfer method, which applies the lithium battery rail grinding vehicle transfer device, and can realize the yard exit operation, yard entry operation, transfer operation and cross-region transfer of the lithium battery rail grinding vehicle.

[0027] The embodiments of the present application will be described in detail below with reference to the accompanying drawings and examples, so that the realization process of how the present application applies technical means to solve technical problems and achieve technical effects can be fully understood and implemented.

[0028] Example 1

[0029] The first embodiment of the present application provides a lithium rail grinding vehicle transfer device, comprising a guide rail sliding mechanism, a lateral translation mechanism, a vertical lifting mechanism and a supporting mechanism. The guide rail sliding mechanism is fixed in the vehicle cabin and can extend out of the vehicle cabin. The lateral translation mechanism is arranged on the guide rail sliding mechanism and can slide laterally along the guide rail sliding mechanism, that is, perpendicular to the extension direction of the guide rail sliding mechanism. The vertical lifting mechanism is arranged on the lateral translation mechanism and is used for lifting the grinding vehicle. The supporting mechanism is arranged at the extension end of the guide rail sliding mechanism, and the lower part of the supporting mechanism can contact the ground to support the extension end of the guide rail sliding mechanism.

[0030] As shown in Figure 1 The lithium rail grinding vehicle transfer device provided by the embodiment is arranged in the vehicle cabin 1, which is carried by the flat car 2, and is used for transferring the lithium rail grinding vehicle.

[0031] The specific structure of the lithium rail grinding vehicle transfer device is shown in Figures 2-4 .

[0032] The guide rail sliding mechanism comprises two side columns 3, a first sliding motor 4, a first lead screw 5, a fixed guide rail 6, a second sliding motor 7, a second lead screw 8, a sliding base 9 and a sliding guide rail 10. The fixed guide rail 6 cooperates with the sliding guide rail 10, the sliding guide rail 10 cooperates with the sliding base 9, the first sliding motor 4 is connected with the first lead screw 5, and the second sliding motor 7 is connected with the second lead screw 8. The fixed guide rail 6 and the sliding guide rail 10 have four groups in common, which are fixed at the four corners in the vehicle cabin. The upper and lower ends of each column 3 are connected with the sliding base 9 through bolts, and the fixed guide rail 6 adjacent to the sliding base 9 is fixed on the vehicle cabin 1.

[0033] When the grinding vehicle needs to slide out of the cabin, the first sliding motor 4 at the rear controls the relative displacement of the sliding guide rail 10 and the fixed guide rail 6 through the first lead screw 5, and the second sliding motor 7 at the front controls the displacement of the sliding base 9 relative to the sliding guide rail 10 through the second lead screw 8, so as to realize the overall sliding of the sliding guide rail and the column out of the cabin and into the cabin, and further drive the lateral translation mechanism and the vertical lifting mechanism to slide out of the cabin or into the cabin.

[0034] The lateral translation mechanism comprises a lateral stepping motor 15, a driving wheel 14, an idler wheel 16, an idler wheel shaft 17, a synchronous belt 19, a guide rail 20, a belt clamp 21 and a sliding block 22, and a housing structure for fixing the devices, such as a stepping motor mounting plate 13, an idler wheel mounting plate 18, a cover plate 11 and a base 12, which bears the above devices. The base 12 is fixed on the upper side of the two upright columns by bolts, and recesses are provided at the two ends of the base 12 to position the stepping motor mounting plate 13 and the idler wheel mounting plate 18, and the base 12 is fixed by bolts. The stepping motor 15 is fixed on one side of the base 12 through the stepping motor mounting plate 13, and a driving wheel 14 is installed on the output shaft of the stepping motor 15. The idler wheel 16 is a driven wheel, which is fixed on the other side of the base 12 through the idler wheel shaft 17 and the idler wheel mounting plate 18. The synchronous belt 18 is sleeved on the driving wheel 14 and the idler wheel 16. The guide rail 20 is fixed on the base 12 by bolts. The sliding block 22 is installed on the guide rail 20 and is fixedly connected with the synchronous belt 19 through the belt clamp 21.

[0035] The lateral sliding of the sliding block 22 can be realized by the rotation of the stepping motor 15. The width of the cover plate 11 is slightly smaller than that of the base 12, so that there is enough gap between the cover plate 11 and the base 12, and the sliding block 22 can pass through the connecting member to be connected with the vertical hoisting mechanism described below.

[0036] The vertical hoisting mechanism comprises a winch assembly, which comprises a winch base 27, a winch motor 25, a reduction box 26, a winch drum 24 and a steel wire rope sling 23, etc. The winch base 27 is fixed with the sliding block 20 in the lateral translation mechanism by bolt connection, and the winch motor 25, the reduction box 26 and the winch drum 24, etc. are installed thereon. The steel wire rope sling 23 is wound on the winch drum 24, and after being connected with the track grinding vehicle, the track grinding vehicle can be lifted and then carried out of the cabin or into the cabin.

[0037] The support mechanism comprises a fixed plate 29, a hydraulic cylinder 28, a piston 33, a transmission rod set 32, a leg rod 30 and a roller 31. The transmission rod set 32 is composed of two connecting rods and is hinged to the middle part of the leg rod 30. The fixed plate 29 is an isosceles triangle, the top corner of which is hinged to the end of the hydraulic cylinder 28, and the two bottom corners are respectively hinged to the ends of the transmission rod set 32 and the leg rod 30. The other end of the leg rod 30 is provided with the roller 31. One end of the piston 33 cooperates with the hydraulic cylinder 28, and the other end is hinged to the transmission rod set 32.

[0038] The support mechanism is in a folded state when it is not working, and is folded at the bottom of the flat car 2. When the guide rail slides out of the cabin, the piston 33 is pushed outward by the hydraulic cylinder 28, and the leg rod 30 is driven downward by the transmission rod set 32 to rotate, so that the roller 31 contacts the ground, providing support for the sliding guide rail 10 suspended out of the cabin, preventing the whole device from shaking and improving stability.

[0039] The lithium electric track grinding vehicle transfer device further comprises a charging device installed in the vehicle cabin for charging the lithium electric track grinding vehicle.

[0040] In this embodiment, the control systems of the first sliding motor 4, the second sliding motor 7, the stepping motor 15, the hoist motor 25 and the hydraulic cylinder 28 are realized according to needs by using prior art means, and will not be described in detail.

[0043] Outbound operation: transport the lithium battery rail grinding vehicle from the warehouse to the operation site.

[0044] Step 1: Crane into the cabin. The running flat car enters the warehouse, the guide rail sliding mechanism moves the horizontal translation mechanism, the vertical lifting mechanism, and the folded support mechanism out of the car cabin by a proper distance, so that the vertical lifting mechanism is located above the lithium battery rail grinding vehicle; the support mechanism opens and lands; the horizontal translation mechanism is moved, so that the vertical lifting mechanism is located above the lifting point of the lithium battery rail grinding vehicle; the vertical lifting mechanism is actuated, so that the steel wire rope sling hook is lowered to the lifting point, and the hook is manually assisted to be fastened, and the lithium battery rail grinding vehicle is lifted upward; the guide rail sliding mechanism moves the lithium battery rail grinding vehicle into the cabin; and the support mechanism is folded.

[0045] Step 2: Road transfer. The flat car transfers the lithium battery rail grinding vehicle from the warehouse to the operation site.

[0046] Step 3: Car release operation. Place the lithium battery rail grinding vehicle on the train track to be operated, and the specific steps are opposite to those of step 1.

[0047] Transfer into the warehouse: transport the lithium battery rail grinding vehicle from the operation site to the warehouse, and the steps are similar to those of the transfer operation steps, and the warehouse and the operation site are exchanged.

[0048] Transfer operation: transport the lithium battery rail grinding vehicle from the operation site to another operation site, and the steps are similar to those of the transfer operation steps, and the warehouse is replaced by the operation site.

[0049] Cross-region transfer: transport the lithium battery rail grinding vehicle from a warehouse or an operation site in one region to a warehouse or an operation site in another region.

[0050] During the cross-region transfer, the lithium battery rail grinding vehicle on the flat car can be charged during transportation.

[0051] It can be seen from the above transition mode that the transition mode using the lithium battery rail grinding vehicle transition device improves the efficiency of hoisting the rail grinding vehicle and reduces manual operation. The transportation efficiency is high, and after loading is completed, long-distance transfer can be directly performed. Charging can be performed during the transportation process, and the lithium battery rail grinding vehicle can have long-time operation capability.

[0052] Finally, it should be noted that: the above examples are only used to illustrate the technical solutions of the present application, but not to limit them; although the present application has been described in detail with reference to the foregoing examples, those skilled in the art should understand that: it can still modify the technical solutions recorded in the foregoing examples, or make equivalent replacement for part of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the spirit and scope of the technical solutions of the embodiments of the present application.
