Problems solved by technology

The power to carry the chassis is usually a worm gear reducer with self-locking function, which transmits power to the feed roller through a chain or bevel gear, and the chain or bevel gear often breaks or breaks under the complex working conditions of the mine, resulting in the loss of the roller Power and self-locking, so that the machine slides along the track, falling off a cliff or hurting people
At the same time, with the disappearance of China's demographic dividend, the problem of expensive and difficult labor in mines has become increasingly prominent. The automatic cutting control of this equipment is difficult to popularize and apply due to the lack of an effective and reliable braking and protection device.

Embodiment 1

[0034] This embodiment provides a brake system for the feed wheel of a guide rail 1 type mine circular saw machine, refer to figure 1 , including two guide rails 1, a traveling device arranged on the two guide rails 1, the traveling device includes a drive assembly 2, two rollers 3 arranged at the output end of the drive assembly 2 and adapted to the two guide rails 1, the drive assembly 2 adopts a reducer and other transmission parts to drive, not described in detail in this embodiment, both guide rails 1 are provided with a stopper assembly 4 that brakes the roller 3; refer to Figure 9 , the two stopper assemblies 4 are connected to each other through the first connecting pipe 10 and the second connecting pipe 11, the first connecting pipe 10 is sleeved in the second connecting pipe 11, and the surface of the second connecting pipe 11 is provided with an adjustment groove 12, corresponding to The surface of the first connecting pipe 10 is provided with a plurality of thread...

Embodiment 2

[0038] The difference between this embodiment 1 and embodiment 2 is: refer to Figure 5, the blocking plate 42 is rotatably provided with an arc-shaped plate 6 above it, the bottom of the arc-shaped plate 6 can be in conflict with the roller 3, the inner surface of the arc-shaped plate 6 can be snapped into the annular groove, and the roller 3 Wrapping, and both sides of the inner surface of the arc-shaped plate 6 are outer chamfer structures that match the two sides of the annular groove; after the roller 3 enters the braking surface structure 43, it will squeeze one end of the arc-shaped plate 6 , so that the arc-shaped plate 6 rotates downward, and the arc-shaped plate 6 wraps the roller 3 after turning downward, so that the arc-shaped plate 6 forms a wrapping buffer for the roller 3. Under the action of the arc-shaped plate 6, it is further effective quickly block the thrust of the roller 3, brake the roller 3, the braking effect is better, and effectively prevent the roll...

Embodiment 3

[0040] refer to Figure 10 The difference between this embodiment and Embodiment 1 is that the separation surface 431 of the braking surface structure 43 in this embodiment is a straight line surface, so that there is a certain angle between the separation surface 431 and the blocking surface 432, effectively preventing the roller 3 Slip between the separation surface 431 and the blocking surface 432, the braking effect is better.

Abstract

The invention discloses a brake system and a brake method for a guide rail type mine disk saw feeding wheel, and relates to the field of mine disk saws. The brake system comprises a guide rail and a walking device arranged on the guide rail; the walking device comprises a driving assembly and a roller arranged at the output end of the driving assembly and matched with the guide rail; a car stop assembly for braking the rollers is arranged on the guide rail; the car stop assembly comprises a mounting plate and a blocking plate arranged on the mounting plate, a braking face structure capable of making contact with the surface of the roller is arranged at the end, close to the roller, of the blocking plate, and the bottom end of the braking face structure is aligned with the surface of the guide rail. After the mine disk saw is braked, the roller enters the brake surface structure of the barrier plate, the roller is separated from the rail under the action of the brake surface structure, a rolling friction pair between the roller and the guide rail is transferred to a sliding friction pair between the roller and the brake surface structure, and the thrust of the roller is blocked by the brake surface structure; therefore, the roller can be effectively and reliably braked.

Description

technical field [0001] The invention relates to the field of mine circular saw machines, and specifically refers to a braking system and a braking method for a feed wheel of a guide rail type mine circular saw machine. Background technique [0002] At present, the track-type mining circular saw machine often has safety accidents because the feed roller is not designed with an over-travel brake or a protective device. The existing feeding method is that the carrier chassis with rollers is fed or rewinded along the guide rail. The power to carry the chassis is usually a worm gear reducer with self-locking function, which transmits power to the feed roller through a chain or bevel gear, and the chain or bevel gear often breaks or breaks under the complex working conditions of the mine, resulting in the loss of the roller Power and self-locking, so that the machine slides along the track, and accidents such as falling off a cliff or hurting people occur. At the same time, with...
