Description

An energy recovery component during braking of a mine hoist

Technical field

The invention relates to the field of mine equipment, and in particular to an energy recovery component during braking of a mine hoist.

Background technique

In the existing technology, the box body of the mine hoist sometimes needs to be braked, and the braking process is mainly completed by the braking assembly. During the braking process, due to the use of hard contact braking, not only the damage to the equipment is Larger, moreover, the energy loss is also large, which not only reduces the service life of the equipment, but also produces huge useless work, which needs to be solved urgently.

Contents of the invention

In order to solve the technical problems existing in the background technology, the present invention proposes an energy recovery component during braking of a mine hoist, which can solve the problems raised by the prior art.

The invention proposes an energy recovery component during braking of a mine hoist, which includes: a box body, a first guide rail, and a second guide rail. The box body is provided with two sets of guide grooves, and a rack is fixed on the box body. The two guide rails are matched with two sets of guide grooves respectively. Several rotating shafts are rotatably connected to the first guide rail. Each rotating shaft is arranged parallel and equidistant along the length direction of the first guide rail. Each rotating shaft is coaxially fixed with a first gear and a second gear. , each first gear is linked through a belt with internal teeth, and a pulley is coaxially fixed on at least one rotating shaft. When the box slides along the first guide rail and the second guide rail, the rack meshes with at least one second gear.

Preferably, the maximum distance between two adjacent second gears is less than the height of the box.

Preferably, the diameter of the first gear is smaller than the diameter of the second gear.

Preferably, the first gear, the second gear, and the pulley are arranged on the rotating shaft in sequence, and the pulley is closest to the first guide rail.

Beneficial effects: The present invention can not only convert useless work during braking of the mine hoist into useful work, but also convert the static friction braking part of the traditional brake pad type into rotational dynamic friction, thereby not only saving energy but also reducing damage to the equipment. , improve the service life of the equipment. If during non-braking, the connection between the pulley and the output end can be disconnected through the clutch device, so that the present invention will not burden the normal use of the mine hoist. This is existing technology and will not be described again.

Detailed ways

As shown in Figure 1, the invention proposes an energy recovery component during braking of a mine hoist, including: a box 1, a first guide rail 2, and a second guide rail 3. The box 1 is provided with two sets of guide grooves 4. A rack 9 is fixed on the body 1. The first guide rail 2 and the second guide rail 3 are respectively matched with two sets of guide grooves 4. A plurality of rotating shafts 5 are rotatably connected to the first guide rail 2. Each rotating shaft 5 is parallel and equidistant along the first guide rail. 2 is arranged in the length direction, each rotating shaft 5 is coaxially fixed with a first gear 6 and a second gear 10, each first gear 6 is linked through a belt 7 with internal teeth, and at least one rotating shaft 5 is coaxially fixed with a pulley. 8. When the box 1 slides along the first guide rail 2 and the second guide rail 3, the rack 9 engages with at least one second gear 10. The maximum distance between two adjacent second gears 10 is less than the height of the box 1 . The diameter of the first gear 6 is smaller than the diameter of the second gear 10 . The first gear 6 , the second gear 10 and the pulley 8 are arranged on the rotating shaft 5 in sequence, and the pulley 8 is closest to the first guide rail 2 .

working principle:

During the actual working process, the hoist is connected to the box 1 through a pull rope, and people or items are transported through the box 1. During the braking process, the box 1 moves up and down and drives one of the second gears 10 to rotate through the rack 9. The rotation of the second gear 10 drives the coaxial rotating shaft 5 to rotate, and the rotating rotating shaft 5 drives the coaxial first gear 6 to rotate. Since the first gears 6 are linked through the belt 7, the rotating third gear 6 is linked to the first gear 6. One gear 6 drives all the first gears 6 to rotate together, and the pulley 8 located on any rotating shaft 5 will rotate accordingly, and the pulley 8 can transfer the kinetic energy through belt transmission for energy conversion and utilization. The transformation and utilization solutions are existing technologies and will not be described again.

The invention can not only convert useless work during braking of the mine hoist into useful work, but also convert the static friction braking part of the traditional brake pad type into rotational dynamic friction, thereby not only saving energy, but also reducing damage to equipment and improving equipment efficiency. service life.

If during non-braking, the connection between the pulley 8 and the output end can be disconnected through the clutch device, so that the present invention will not burden the normal use of the mine hoist. This is existing technology and will not be described again.

The above are only preferred specific embodiments of the present invention, but the protection scope of the present invention is not limited thereto. Any person familiar with the technical field can, within the technical scope disclosed in the present invention, implement the technical solutions of the present invention. Equivalent substitutions or changes of the inventive concept thereof shall be included in the protection scope of the present invention.
