Description

Technical Field

[0001] This utility model relates to the field of railway maintenance, and in particular to a rust removal device for railway track joint bolts. Background Technology

[0002] In open-air environments, sleeper bolts rust quickly, leading to reduced bolt strength. Therefore, regular rust removal and oiling are necessary. Common bolt rust removal is done manually, which requires significant manpower and is inefficient. Furthermore, the surrounding sleeper surfaces are also susceptible to rust, and manual grinding is inconvenient for thoroughly cleaning these areas, resulting in incomplete rust removal. Utility Model Content

[0003] The purpose of this invention is to solve the problems of low efficiency in bolt grinding and inconvenience in grinding the surface of the sleepers around the bolts when workers grind bolts. It provides a rust removal device for railway track joint bolts that facilitates grinding the surface of the sleepers around the bolts, removes rust more thoroughly, and brushes the bolts up and down during the grinding process to improve grinding efficiency.

[0004] The technical implementation scheme of this utility model is as follows: a rust removal device for railway track joint bolts, including a sleeve, two bolts are provided on the sleeper, the sleeve is located above one of the bolts, the middle part of the sleeve is hollowed out, a motor is fixedly connected inside the sleeve, a transmission sleeve is fixedly connected to the output shaft of the motor, a transmission column is fixedly connected to the bottom of the transmission sleeve, the transmission column and the sleeve are rotatably connected, and a grinding component is provided at the bottom of the transmission column.

[0005] Furthermore, the grinding component includes a grinding cylinder, which is fixedly connected to the bottom of the transmission column. The grinding cylinder and the sleeve are rotatably connected, and the grinding cylinder is provided with several steel bristles inside.

[0006] Furthermore, it also includes a contact plate, which is rotatably connected to the bottom surface of the grinding cylinder.

[0007] Furthermore, the polishing component also includes a polishing disc, which is fixedly connected to the bottom of the polishing cylinder.

[0008] Furthermore, it also includes pressure frames, with two pressure frames slidably connected to the grinding cylinder. The two pressure frames are symmetrically arranged, and a brush plate is fixedly connected to each of the two pressure frames. A return spring is connected between each of the two pressure frames and the sleeve. Several convex balls are fixedly connected to the sleeve, and the convex balls are located above the pressure frames.

[0009] The present invention has the following advantages: 1. The motor output shaft rotates to drive the transmission column to rotate, and the transmission column rotates to drive the grinding cylinder to rotate. The steel bristles inside the grinding cylinder grind the bolts, thus realizing the grinding of automatic bolts. At the same time, the grinding cylinder drives the grinding disc to rotate to grind the surface of the sleepers around the bolts, removing the rust on the sleeper surface near the bolts. Rust removal is convenient and thorough.

[0010] 2. When the grinding cylinder rotates, it drives the pressure frame to rotate. The pressure frame rotates and comes into contact with the convex ball. The convex ball will squeeze the pressure frame, and the pressure frame will drop due to the squeeze. The return spring is compressed. After the convex ball and the pressure frame separate, the return spring drives the pressure frame to return to its original position. In this way, during the rotation of the grinding cylinder, the brush plate on the pressure frame will move up and down. This will brush the bolt up and down during the grinding process, improving the grinding efficiency. Attached Figure Description

[0017] References to embodiments herein mean that a particular feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of the present invention. The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment mutually exclusive with other embodiments. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.

[0018] Example 1: A rust removal device for railway track joint bolts, such as... Figures 1-5As shown, it includes a sleeve 4, and two bolts 2 are provided on the sleeper 1. The sleeve 4 is located above one of the bolts 2. The middle part of the sleeve 4 is hollowed out. A motor 5 is fixedly connected inside the sleeve 4. A transmission sleeve 6 is fixedly connected to the output shaft of the motor 5. The rotation of the output shaft of the motor 5 will drive the transmission sleeve 6 to rotate. A transmission column 7 is fixedly connected to the bottom of the transmission sleeve 6. The transmission column 7 and the sleeve 4 are rotatably connected. A grinding component is provided at the bottom of the transmission column 7.

[0019] The grinding component includes a grinding cylinder 8, which is fixedly connected to the bottom of the transmission column 7. The grinding cylinder 8 and the sleeve 4 are rotatably connected. The grinding cylinder 8 has several steel bristles inside and is used to remove rust from the surface of the bolt.

[0020] It also includes a contact plate 9, which is rotatably connected to the bottom surface of the grinding cylinder 8 and is used to support the grinding cylinder 8.

[0021] The polishing component also includes a polishing disc 10, which is fixedly connected to the bottom of the polishing cylinder 8.

[0022] Initially, the worker holds the sleeve 4 and presses the device down onto the bolt 2 that needs to be ground, causing the bolt 2 to extend into the grinding cylinder 8. After the contact plate 9 contacts the sleeper 1, the worker stops pressing down and then starts the motor 5. The output shaft of the motor 5 rotates, driving the transmission column 7 to rotate, which in turn drives the grinding cylinder 8 to rotate. The steel bristles inside the grinding cylinder 8 grind the rust on the bolt 2. Since the contact plate 9 and the grinding cylinder 8 are rotatably connected, the contact plate 9 provides support for the device. The grinding cylinder 8 drives the grinding disc 10 to rotate, grinding the surface of the sleeper 1 around the bolt 2 and removing the rust near the bolt 2. The rust removal is convenient and thorough.

[0023] Example 2: Based on Example 1, such as Figures 2-5 As shown, it also includes a pressure frame 11. Two pressure frames 11 are slidably connected to the grinding cylinder 8. The two pressure frames 11 are symmetrically arranged. A brush plate 12 is fixedly connected to each of the two pressure frames 11. A return spring 13 is connected between each of the two pressure frames 11 and the sleeve 4. The return spring 13 is used to drive the pressure frame 11 to return to its original position. Several protruding balls 14 are fixedly connected to the sleeve 4. The protruding balls 14 are located above the pressure frames 11.

[0024] When the grinding cylinder 8 rotates, it drives the pressure frame 11 to rotate. The pressure frame 11 rotates and comes into contact with the convex ball 14. The convex ball 14 will squeeze the pressure frame 11. The pressure frame 11 will drop due to the squeeze, and the return spring 13 will be compressed. After the convex ball 14 and the pressure frame 11 separate, the return spring 13 will drive the pressure frame 11 to return to its original position. In this way, during the rotation of the grinding cylinder 8, the brush plate 12 on the pressure frame 11 will move up and down. This will brush the bolt 2 up and down during the grinding process, improving the grinding efficiency.

[0025] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model and are not intended to limit the scope of protection of this utility model. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the essence and scope of the technical solutions of this utility model.
