Description

Technical Field

[0001] The utility model relates to the technical field of rail profile grinding, in particular to a rail profile grinding trolley with adjustable angle. Background Art

[0002] Rail grinding is an important part of line repair work. Through grinding, rail surface defects such as fatigue cracks, peeling, corrugation, abrasions, dents, fat edges, uneven wear, and poor light band can be effectively solved.

[0003] Existing grinding instruments can only be used to grind a certain part of the rail, but the position that needs to be polished may be in the rail profile, rail surface, rail waist and other parts. At the same time, it is also necessary to grind the fat edge and the switch. Therefore, only one position can be polished at a time and it cannot meet the grinding needs that appear immediately on a rail, thus causing the problem of repeated operations on a rail.

[0027] The following will describe the implementation methods of the present application in detail with the help of accompanying drawings and examples, so that the implementation process of how the present application uses technical means to solve technical problems and achieve technical effects can be fully understood and implemented accordingly.

[0028] In the description of the present invention, it should be understood that the terms "upper", "lower", "front", "back", "left", "right", "top", "bottom", "inside", "outside", etc., indicating directions or positional relationships, are based on the directions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore should not be understood as a limitation on the present invention.

[0029] Figure 1-Figure 5As an embodiment of the utility model, a rail profile grinding trolley with multi-degree-of-freedom angle adjustment is designed according to the requirements of rail profile and grinding efficiency. It can effectively play the role of grinding the rail profile and the rail surface and rail waist, grinding the fat edge and grinding the turnout, so that the designed grinding trolley can be used in different working scenarios, improving the existing grinding instruments that can only be used for grinding operations on a certain part of the rail. The deficiency of single function is a technical problem that this scheme urgently needs to solve. Based on the above, this scheme describes an angle-adjustable rail profile grinding trolley, which is provided with a rail tightening device 1 for driving the structure connected to it to move synchronously on the rail, and provide a tightening force to maintain overall stability during the self-moving process, so as to avoid the overall device from tipping over when adjusting the angle to grind the side of the rail head, and on this basis, the steering mechanism is used in conjunction with the mobile bracket 313 to adjust the grinding direction of the grinding and detection unit 4, thereby improving the problem that it can only be used for grinding operations on a certain part of the rail.

[0030] The box body 2 is installed on the rail tightening device 1 and establishes a bearing space. A battery is arranged in the box body 2 to provide a power source for the entire device. At the same time, the function of the box body 2 is also reflected in that it can wrap part of the structure of the linkage device 3 inside, effectively reducing the entry of dust, debris, etc. generated by the entire device during the work of grinding the rail surface profile, thereby greatly improving the service life of the grinding device.

[0031] like Figure 2 , Figure 3 As shown, the linkage device 3 is arranged at one end of the box body 2 and extends in a direction away from the box body 2 to establish a basis for angular rotation. It is provided with a lateral rotation mechanism 31 and a lifting device 32, wherein the lateral rotation device includes a steering platform 311 and a connecting block 312 connected to the steering platform 311 and a movable bracket 313, the steering platform 311 includes a gear set 314 installed on the box body 2 and a rotating wheel 315 installed on the gear set 314, and the gear set 314 is provided with two cylindrical gears in this specific embodiment. As shown in the figure, the rotating wheel 315 is rotated by The bolts are installed on the cylindrical gear at the lower end, and the connecting block 312 is connected to one end of the rotating wheel 315 facing away from the box body 2. The connecting block 312 is in the shape of a straight plate and is installed between the rotating wheel 315 and the movable bracket 313 by rotating through the rotating shaft 316. The movable bracket 313 provides a basis for the installation of the lifting device 32. The rotating shaft 316 extends longitudinally on the connecting block 312 and the rotating wheel 315 and the connecting structure with the movable bracket 313. The connecting plate 42 rotates horizontally around the rotating shaft 316, so that the grinding head 43 can grind the rail surface back and forth horizontally.

[0032] like Figure 3As shown, the lifting device 32 includes a connecting support 321 connected to the mobile bracket 313. Two connecting supports 321 are symmetrically arranged on the left and right. A connecting rod 322 is arranged between the two connecting supports 321. The connecting rod 322 is rotatably installed on one connecting support 321. The connecting support 321 is fitted with the connecting plate 42 and assembled together by bolt connection. At the same time, the connecting support 321 is also bolted to the handrail. The rail grinding personnel hold the handrail and rotate on the other connecting support 321 through the connecting rod 322. Figure 2 As shown, by rotating with the connecting support 321 located on the right side, the vertical upward and downward movement operation of the grinding and testing unit 4 can be realized.

[0033] like Figure 4 As shown, the rail tightening device 1 includes a frame 11 and a rail wheel installed at the lower end of the frame 11 for walking on the top surface of the rail. A tightening wheel 12 for tightening the rail waist is arranged on the frame 11 at the lower end of the rail wheel, so that the whole device can walk on the rail. At the same time, two rows of rail tightening wheels 12 symmetrically arranged front and back can ensure that the whole device will not tip over when adjusting the angle to grind the side of the rail head.

[0034] The grinding and detection unit 4 is connected to the box body 2 through the linkage device 3 and acts on the rail in multiple directions under the action of the linkage device 3. It is specifically provided with a mounting frame 41. The mounting frame 41 is provided with a connecting plate 42 connected with the connecting support 321 at the left end from left to right. A handrail for the operator to grasp is connected to the side wall of the connecting plate 42 by bolts. A motor and a laser displacement sensor 44 are provided at the left end of the connecting plate 42. A grinding head 43 is connected to the lower end of the motor through a coupling. The laser displacement sensor 44 can detect the flatness of the rail surface to determine whether the rail surface needs to be ground and trimmed. At the same time, after the grinding operation, the laser displacement sensor 44 can also be used to detect whether the effect of the device grinding the rail surface is flat and whether it meets the requirements of the grinding rail specification.

[0035] The control method of the present invention is automatic control through a controller. The control circuit of the controller can be realized by simple programming by technicians in this field. The provision of power is also common knowledge in this field. The present invention is mainly used to protect mechanical devices, so the present invention will no longer explain the control method and circuit connection in detail.
