Description

Technical Field

[0001] This utility model relates to the field of railway sleeper surface treatment technology, and more specifically, to a railway sleeper grinding device. Background Technology

[0002] Concrete sleepers are widely used in rail transit. In the current production process of concrete sleepers, grinding equipment is often used to grind the uneven edges of the sleepers.

[0003] Announcement No. CN220660265U discloses a concrete sleeper edge grinding device. This device raises and lowers a slider by activating an electric lifting component inside the lifting column. The slider's movement, in turn, raises and lowers the mounting frame and grinding wheel, thus adjusting the grinding height. Activating a first motor rotates a first rotating rod, which in turn rotates a second motor and the grinding wheel, allowing adjustment of the grinding angle. A hand-held handle pushes the rollers, enabling the entire device to move and adjust, facilitating grinding work. However, manual assistance is required for movement, and each cycle can only grind one sleeper, indicating that grinding efficiency needs improvement. Utility Model Content

[0004] The purpose of this utility model is to solve the problems mentioned in the background art and to propose a sleeper grinding device.

[0005] The technical solution adopted by this utility model to solve its technical problem is:

[0006] A railway sleeper grinding device includes a placement platform, a placement groove, a front-to-back moving assembly, a fixing plate, a second telescopic component, a mounting plate, a servo motor, a mounting rod, a drive motor, a grinding disc, and sandpaper.

[0007] Several placement slots are equidistantly arranged on the placement platform;

[0008] The forward and backward moving components are set on the placement platform and the forward and backward moving components are provided with fixed plates that correspond one-to-one with the placement slots;

[0009] The second telescopic component is mounted on the fixed plate and connected to the mounting plate, and a servo motor is mounted on the mounting plate;

[0010] The mounting rod is connected to a servo motor and a drive motor is installed on the mounting rod;

[0011] The grinding disc is connected to the drive motor at the center and sandpaper is movably mounted on the grinding disc.

[0012] Furthermore, the forward and backward moving assembly includes a first telescopic member, a moving plate, a track, and a telescopic rod. The first telescopic member and the telescopic rod are both mounted on the placement platform and both are connected to the moving plate. The placement platform is provided with a track that slides with the moving plate. Several fixed plates are equidistantly arranged on the moving plate, and a rectangular hole is opened in the lower area of ​​the moving plate.

[0013] The above solution enables multiple grinding discs to move in the front-back direction through the forward and backward moving components. Combined with the movement of the second telescopic component, servo motor, and drive motor, the grinding of the upper surface of the sleeper can be automatically completed by the sandpaper.

[0014] Furthermore, a rubber pad is provided at the bottom of the placement groove.

[0015] In the above solution, the rubber pad can prevent the sleeper from making hard contact with the placement platform during placement, which would cause wear.

[0016] Furthermore, the mounting plate is provided with fixing rods spaced apart from the servo motor, and a chip blowing fan is inclinedly mounted on the fixing rods.

[0017] In the above solution, the chip blowing fan is always working during the grinding process to blow away the chips and reduce the amount of chips remaining on the placement table.

[0018] Furthermore, sandpaper is attached to the polishing disc via Velcro.

[0019] Furthermore, the placement platform is provided with several lifting rings.

[0020] The above solution allows the device to be moved to any designated location using lifting rings and hoisting equipment, eliminating the need for manual handling.

[0021] Compared with the prior art, the beneficial effects of this utility model are:

[0022] Compared to existing technologies, this device can automatically grind the surface of the sleepers without manual intervention. It can also grind multiple sleepers in one cycle, thus improving grinding efficiency, increasing automation, and ensuring the quality of the sleepers during subsequent use.

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present utility model, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model. The present utility model will be further described with reference to the accompanying drawings and embodiments:

[0029] like Figures 1 to 3 As shown, a sleeper grinding device includes a placement platform 1, a placement groove 2, a front-to-back moving assembly, a fixing plate 7, a second telescopic component 8, a mounting plate 9, a servo motor 10, a mounting rod 11, a drive motor 12, a grinding disc 13, and sandpaper 14.

[0030] Several placement slots 2 are equidistantly opened on the placement platform 1 (an optimization of the scheme, with rubber pads provided at the bottom of the placement slots 2, which are not shown in the figure);

[0031] The front-to-back moving component is set on the placement platform 1 and a fixing plate 7 corresponding to the placement slot 2 is fixed on the front-to-back moving component;

[0032] The second telescopic component 8 is fixed on the fixed plate 7 and connected to the mounting plate 9. A servo motor 10 is fixed on the mounting plate 9.

[0033] The mounting rod 11 is connected to the servo motor 10 and the drive motor 12 is fixed on the mounting rod 11.

[0034] The grinding disc 13 is centrally connected to the drive motor 12, and sandpaper 14 is movably mounted on the grinding disc 13 (specifically, sandpaper 14 is attached to the grinding disc 13 by Velcro).

[0035] Further refinements of the embodiments of this utility model, such as... Figure 1 As shown, the forward and backward moving assembly includes a first telescopic component 3, a moving plate 4, a track 5, and a telescopic rod 6. The first telescopic component 3 and the telescopic rod 6 are both fixed on the placement platform 1 and both are connected to the moving plate 4. The placement platform 1 is provided with a track 5 that slides with the moving plate 4. Several fixed plates 7 are fixed at equal intervals on the moving plate 4, and a rectangular hole is opened in the lower area of ​​the moving plate 4. The rectangular hole is not shown in the figure.

[0036] Further refinements of the embodiments of this utility model, such as... Figure 3 As shown, a fixing rod 15 is fixed on the mounting plate 9 at intervals from the servo motor 10, and a chip blower 16 is fixedly mounted on the fixing rod 15 at an angle.

[0037] It should be noted that the first telescopic component 3, the second telescopic component 8, the servo motor 10, the drive motor 12, and the chip blowing fan 16 are all electrically connected to the controller. The controller is not shown in the figure. It can be specifically set on the outer wall of the placement platform 1 where the first telescopic component 3 and the telescopic rod 6 are installed.

[0038] The working process of this utility model is as follows:

[0039] First, place the sleeper in the placement slot 2 that matches its size. One sleeper is placed in one placement slot 2. After all the sleepers are placed in all the placement slots 2, the upper surface of the sleeper is higher than the placement slot 2. In this application, the upper surface of the sleeper is ground. The placement slot 2 can prevent the sleeper from shifting position during the grinding process.

[0040] The controller then controls the first telescopic component 3 to work, thereby driving the moving plate 4 to move forward along the track 5. When the moving plate 4 moves a predetermined distance, the first telescopic component 3 stops working. During the movement, the telescopic rod 6 can provide guidance and extend the service life of the first telescopic component 3. At this time, the grinding disc 13 is above one end of the sleeper.

[0041] Before grinding, the running trajectory of the grinding wheel is set in the controller (specifically including lifting and deflection, ensuring that the shape and size of the sleepers to be ground are consistent and that all sleepers are placed in the same orientation, without being upside down or reversed). At the same time, the intermittent start and stop cycle and movement speed of the first telescopic component 3 are set. This allows for effective grinding of different areas on the surface of the sleepers. During the grinding process, the moving plate 4 will not contact the sleepers due to the presence of the rectangular holes, and the two will always maintain a distance. In addition, since the grinding disc 13 is large, it does not need to move left and right during the grinding process. It only needs to move back and forth and cooperate with the second telescopic component 8, drive motor 12, servo motor 10 and grinding sandpaper 14 to achieve effective grinding of the surface of several sleepers at the same time.

[0042] During the grinding process, the chip blower 16 is always in operation to blow away the debris on the sleepers. When the first telescopic component 3 drives the moving plate 4 to the farthest position (i.e., the end area of ​​the sleeper) according to the program preset by the controller, the grinding process of multiple sleepers can be completed automatically.

[0043] Then the controller first controls several second telescopic components 8 to retract, thereby driving several grinding discs 13 to move upward. Then the controller controls the first telescopic component 3 to retract so that the grinding discs 13 are away from the top of the sleepers. Finally, several sleepers are unloaded and transferred in succession, and a new round of sleeper grinding process can begin.

[0044] Compared to existing technologies, this device can automatically grind the surface of the sleepers without manual intervention, and can complete the grinding process of multiple sleepers in one round of processing, thereby improving grinding efficiency.

[0045] In some embodiments, the placement platform 1 is provided with a plurality of lifting rings; this embodiment is not shown in the figure; in this embodiment, the device can be transferred to a designated location at will by means of lifting rings and hoisting equipment, without the need for manual handling.

[0046] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The descriptions of the above embodiments and specifications are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of protection claimed by this utility model.
