Description

Technical Field

[0001] This utility model relates to the technical field of railway track maintenance equipment, specifically a cleaning device for railway tracks. Background Technology

[0002] As a critical infrastructure of the railway transportation system, railway tracks directly affect the safety and stability of train operation. During daily use, dust, gravel, oil, and other impurities easily accumulate on the track surface and sides, which not only accelerates track wear but can also cause train malfunctions. Therefore, track cleaning and maintenance are essential for ensuring the normal operation of the railway transportation system.

[0003] Currently, various railway track cleaning devices exist in the prior art. For example, patent CN219862606U discloses a railway track cleaning and maintenance mechanism. This mechanism, by setting cleaning nozzles on a moving component, can automatically clean the outer surface of the track, improving cleaning efficiency to some extent. However, in practical applications, this device still has significant limitations. On the one hand, it lacks a dedicated cleaning structure for the sides of the track, making it difficult to remove dirt from the sides, creating cleaning blind spots and affecting the overall track cleaning effect. On the other hand, the fixed spacing between the bottom wheels of the device makes it unsuitable for railway tracks with different gauges (such as standard gauge and broad gauge), resulting in poor versatility in railway maintenance operations with different track types, greatly limiting the application scope of the equipment.

[0004] In summary, there is an urgent need to develop a railway track cleaning device that can effectively clean impurities from the sides of railway tracks and whose wheel spacing is adjustable to adapt to various track types. Utility Model Content

[0005] To address the problems mentioned in the background art, the purpose of this utility model is to provide a cleaning device for railway tracks, which has the advantages of side cleaning and adjustable travel distance. It solves the problems of existing devices not having a cleaning structure for the side of the rail, making it difficult to remove dirt from the side of the rail, forming a cleaning blind spot, affecting the overall cleaning effect of the track, and the fixed travel wheel spacing at the bottom of the device, which cannot adapt to railway tracks with different gauges.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a cleaning device for railway tracks, comprising a first frame and a second frame, the second frame being disposed on the right side of the first frame, an mounting block being fixedly installed on the front of the first and second frames, a brush rod being fixedly installed on the left and right sides of the bottom of the mounting block, bristles being fixedly connected to the surface of the brush rod, the bristles being arranged in multiple and evenly distributed in a ring, a spacing adjustment mechanism being fixedly connected to the front and rear sides of the top of the first and second frames, the spacing adjustment mechanism comprising a screw rod, the screw rod being fixedly connected to the front and rear sides of the top of the first and second frames, an adjustment frame being disposed on the top of the first and second frames, the adjustment frame having four adjustment slots inside that cooperate with the four screw rods, a locking block being threadedly connected to the top of the surface of the screw rod, and a synchronization component being fixedly connected to the middle position of the bottom of the first and second frames.

[0007] As a preferred embodiment of the present invention, the synchronization component includes a synchronization block, which is fixedly connected to the middle position at the bottom of the first frame and the second frame, and the synchronization block is internally threaded with a bidirectional lead screw.

[0008] As a preferred embodiment of this utility model, mounting rods are fixedly connected to the front and rear sides of the left side of the first frame and the front and rear sides of the right side of the second frame, and train wheels are movably connected to the surface of the mounting rods.

[0009] As a preferred embodiment of this invention, the left and right sides of the bottom of the adjustment frame are fixedly connected to stabilizing blocks, and the bidirectional lead screw is movably connected inside the stabilizing blocks via bearings.

[0010] As a preferred embodiment of this utility model, a traction frame is fixedly connected to the front of the adjustment frame, and a pin is inserted into the front side of the traction frame.

[0011] As a preferred embodiment of this invention, the locking block is arranged in a plum blossom shape.

[0012] As a preferred embodiment of this invention, a counterweight box is fixedly installed at the middle position of the top of the adjustment frame.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0014] 1. This utility model, by installing brush rods with bristles on the front of the first and second frames, can effectively clean the sides of the rails, ensuring that all surfaces of the rails are cleaned, improving the cleaning effect, reducing wear caused by dirt accumulation, and extending the service life of the rails. The spacing adjustment mechanism, in conjunction with the synchronization component, allows for flexible adjustment of the spacing between the first and second frames, greatly improving the versatility and applicability of the equipment, reducing railway maintenance costs, and solving the problems of existing devices that do not have a cleaning structure for the sides of the rails, making it difficult to remove dirt from the sides of the rails, creating cleaning blind spots, affecting the overall cleaning effect of the track, and the fixed spacing of the bottom traveling wheels of the device, which cannot adapt to railway tracks of different gauges. It achieves the effect of side cleaning and adjusting the traveling distance.

[0015] 2. By setting up a synchronization component, this utility model can realize the synchronous adjustment of the distance between the first frame and the second frame through the cooperation of the bidirectional lead screw and the synchronization block. When the bidirectional lead screw is rotated, the synchronization blocks on both sides move in opposite directions, causing the first frame and the second frame to move closer or further away synchronously, ensuring that the cleaning mechanism is always aligned with the track. This design avoids frame offset caused by unilateral adjustment and improves the adjustment accuracy.

[0016] 3. This utility model, by setting up an installation rod and train wheels, with the train wheels having a tapered contact surface with the track, and in conjunction with the movable connection of the installation rod, can automatically adapt to track curves, improving the equipment's passability on curved tracks and reducing the risk of maintenance interruptions. When the equipment enters a curve, the contact point between the train wheel's tapered surface and the track changes, generating centripetal force to automatically guide the wheel assembly. The movable connection of the installation rod allows the wheel assembly to swing slightly, further reducing the risk of derailment. Attached Figure Description

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] like Figures 1 to 3 As shown, the present invention provides a cleaning device for railway tracks, including a first frame 1 and a second frame 2. The second frame 2 is located on the right side of the first frame 1. A mounting block 3 is fixedly installed on the front of the first frame 1 and the second frame 2. Brush rods 4 are fixedly installed on the left and right sides of the bottom of the mounting block 3. Brush bristles 13 are fixedly connected to the surface of the brush rods 4. Multiple brush bristles 13 are arranged in a ring and evenly distributed. A spacing adjustment mechanism 5 is fixedly connected to the front and rear sides of the top of the first frame 1 and the second frame 2. The spacing adjustment mechanism 5 includes a screw 51. The screw 51 is fixedly connected to the front and rear sides of the top of the first frame 1 and the second frame 2. An adjustment frame 52 is provided on the top of the first frame 1 and the second frame 2. The adjustment frame 52 has four adjustment slots 53 inside that cooperate with the four screws 51. A locking block 54 is threadedly connected to the top of the surface of the screw 51. A synchronization component 6 is fixedly connected to the middle position of the bottom of the first frame 1 and the second frame 2.

[0023] refer to Figure 1 and Figure 2 The synchronization component 6 includes a synchronization block 61, which is fixedly connected to the middle position of the bottom of the first frame 1 and the second frame 2. The synchronization block 61 is internally threaded with a bidirectional lead screw 62.

[0024] As a technical optimization of this utility model, by setting a synchronization component 6, the synchronization distance between the first frame 1 and the second frame 2 can be adjusted through the cooperation of the bidirectional lead screw 62 and the synchronization block 61. When the bidirectional lead screw 62 is rotated, the synchronization blocks 61 on both sides move in opposite directions, causing the first frame 1 and the second frame 2 to move closer or further away synchronously, ensuring that the cleaning mechanism is always aligned with the track. This design avoids frame offset caused by unilateral adjustment and improves adjustment accuracy.

[0025] refer to Figure 1 and Figure 2 Mounting rods 7 are fixedly connected to the front and rear sides of the left side of the first frame 1 and the front and rear sides of the right side of the second frame 2. Train wheels 8 are movably connected to the surface of the mounting rods 7.

[0026] As a technical optimization of this utility model, by setting up an installation rod 7 and a train wheel 8, the contact surface between the train wheel 8 and the track adopts a conical design. With the movable connection of the installation rod 7, it can automatically adapt to the curve of the track, improve the passability of the equipment on curved tracks, and reduce the risk of maintenance interruption. When the equipment enters the curve, the contact point between the conical surface of the train wheel 8 and the track changes, generating centripetal force to automatically guide the wheel set. The movable connection of the installation rod 7 allows the wheel set to swing slightly, further reducing the risk of derailment.

[0027] refer to Figure 1 and Figure 2 The bottom left and right sides of the adjustment frame 52 are fixedly connected to the stabilizing blocks 9, and the bidirectional lead screw 62 is movably connected to the inside of the stabilizing blocks 9 through bearings.

[0028] As a technical optimization of this utility model, by setting a stabilizing block 9, the stabilizing block 9 provides additional support for the bidirectional lead screw 62. The bearing connection reduces the rotational resistance of the lead screw, enhances the structural rigidity, reduces vibration and wear, and extends the service life of the equipment. The bearing converts the rotational friction of the lead screw into rolling friction, reducing energy consumption. The stabilizing block 9 distributes the force on the lead screw to the adjusting frame 52, avoiding deformation caused by local stress concentration and ensuring the stability of the spacing adjustment.

[0029] refer to Figure 1 and Figure 2 The front of the adjusting frame 52 is fixedly connected to the traction frame 10, and the front side of the traction frame 10 is inserted with a pin 11.

[0030] As a technical optimization of this utility model, by setting up a traction frame 10 and pins 11, the standardized design of the traction frame 10 can quickly connect to various power sources, and the connection method of the pins 11 facilitates the rapid deployment and disassembly of the equipment. The traction frame 10 is connected to the power equipment through the pins 11 to form a hinged structure, which allows the equipment to turn on the track. The quick insertion and removal design of the pins 11 allows a single person to complete the equipment assembly, shortening the preparation time for operation.

[0031] refer to Figure 1 and Figure 2 Locking block 54 is set in a quincunx pattern.

[0032] As a technical optimization of this utility model, by setting the locking block 54 as a plum blossom shape, the operator can manually tighten the locking block 54 without tools. The plum blossom shape provides multiple force application points, increasing the friction torque of the hand. After the locking block 54 is tightened, the position of the adjusting bracket 52 is fixed by the thread self-locking, preventing loosening due to vibration during operation.

[0033] refer to Figure 1 and Figure 2 A counterweight box 12 is fixedly installed at the middle position of the top of the adjusting frame 52.

[0034] As a technical optimization of this utility model, by setting a counterweight box 12, the center of gravity of the equipment can be adjusted by adding counterweights, thereby enhancing the stability during cleaning. The counterweight box 12 can be filled with heavy objects such as sand and iron blocks. By changing the weight distribution, the position of the center of gravity of the equipment is optimized, ensuring that the brush bristles 13 always maintain effective contact pressure with the track surface.

[0035] The working principle and usage process of this utility model are as follows: During use, according to the track gauge of the railway track to be cleaned, the operator manually rotates the plum blossom-shaped locking block 54 on the screw 51 of the spacing adjustment mechanism 5 to release the fixed state of the adjustment frame 52. Then, the double-acting screw 62 is rotated. As the double-acting screw 62 rotates, it drives the synchronizing block 61 to move in opposite directions at the bottom of the first frame 1 and the second frame 2, causing the first frame 1 and the second frame 2 to move closer or further apart synchronously until the distance between them matches the current track type. After adjustment, the locking block 54 is tightened again to fix the adjustment frame 52, ensuring stable operation of the cleaning device on the track. The cleaning device is connected to an external power source, such as a railcar or electric traction vehicle, via the traction frame 10 and pins 11, providing the cleaning device with propulsion power. Simultaneously, according to cleaning requirements, a suitable weight can be added to the counterweight box 12 to adjust the equipment's center of gravity and enhance the cleaning process. The stability of the process is ensured, and then an external power source is activated to drive the cleaning device along the railway track. During the movement, the brush bar 4 installed on the front of the first frame 1 and the second frame 2 has bristles 13 on its surface in close contact with the side of the rail. As the device moves, the bristles 13 gradually remove dust, gravel, oil and other impurities attached to the side of the rail through friction. The bristles 13 are made of wear-resistant and elastic material. When in contact with the side of the rail, they can penetrate into the fine gaps on the rail surface and peel off the dirt from the rail surface through physical friction, thus effectively cleaning the side of the rail and filling the cleaning blind spots of traditional cleaning devices. The cleaning device continues to move forward, and the brush bar 4 and bristles 13 continuously clean the side of the rail. At the same time, the train wheels 8 at the bottom of the first frame 1 and the second frame 2 roll on the track to ensure the smooth operation of the cleaning device until the cleaning work of a section of track is completed.

[0036] In summary, this railway track cleaning device, by installing brush rods 4 with bristles 13 on the front of the first frame 1 and the second frame 2, can effectively clean the sides of the rails, ensuring that all surfaces of the rails are cleaned, improving the cleaning effect, reducing wear caused by dirt accumulation, and extending the service life of the rails. The spacing adjustment mechanism 5, in conjunction with the synchronization component 6, allows for flexible adjustment of the spacing between the first frame 1 and the second frame 2, greatly improving the versatility and applicability of the equipment, reducing railway maintenance costs, and solving the problems of existing devices lacking a cleaning structure for the sides of the rails, making it difficult to remove dirt from the sides of the rails, creating cleaning blind spots, affecting the overall cleaning effect of the track, and the fixed spacing of the bottom traveling wheels of the device, which cannot adapt to railway tracks of different gauges.
