Abstract
The invention discloses a round-link chain loosing maintenance device for a mine chain bucket elevator. The round-link chain loosing maintenance device is characterized in that a reverse wheel A and a reverse wheel B are installed on a platform; the reverse wheel B is installed on the platform through an advancing slideway; a thrust oil cylinder is installed below the platform; and an advancing oil cylinder is installed below the reverse wheel B. When the round-link chain slack maintenance device works, the round-link chains are in stationary state; then an operator can start the advancing oil cylinder to enable the reverse wheel B to move towards the reverse wheel A along the advancing slideway until the two reverse wheels are meshed with each other; then the operator can start the thrust oil cylinder and raises the platform through a hinge mechanism on the platform, and then the round-link chain on the reverse wheel A slides downwards and simultaneously drives the reverse wheel A to rotate; the reverse wheel A and the reverse wheel B rotate simultaneously, and when the round-link chain on the reverse wheel A is strained, the round-link chain on the reverse wheel B can be in the loosed state. The round-link chain loosing maintenance device ensures the safe operation during the maintenance which requires the round-link chains to be loosed. The round-link chain loosing maintenance device is simple to operate without requiring any special tool, and the maintenance time is reduced.
Description
Affiliated technical field
The present invention relates to a kind of loosening maintenance device of round-link chain, especially a kind of loosening maintenance device of mine chain-bucket hoist round-link chain.
Background technology
At present, mine hoist of the prior art need to arrange large-scale derrick or headframe at well head usually; by motor, steel rope, skip bucket etc. are finished straight up and down Lifting Convey work; owing to need to shut down conversion when lifting straight up and down replaces; so work efficiency is low, shaft section is long-pending large in addition, so great in constructing amount; the space that takies is also large; its complicated structure, Operation and maintenance are cumbersome, and cost is high.Mounting circular ring chain-drive chain bucket elevator can address the above problem, and needs special tool that round-link chain is lax but will solve this mine chain-bucket hoist maintenance, complicated operation, the problem that maintenance is difficult.
Summary of the invention
The deficiency that exists in order to overcome existing mine chain-bucket hoist, the invention provides a kind of loosening maintenance device of mine chain-bucket hoist round-link chain, this device can guarantee the safe in operation of mine chain-bucket hoist when carrying out the lax maintenance of round-link chain, this device is simple to operate, do not need special tool, reduced the time that the lax maintenance of round-link chain consumes.
The technical solution adopted for the present invention to solve the technical problems is: the reverse wheel A of mine chain-bucket hoist, reverse wheel B are installed on the same platform, reverse wheel B is installed on the platform by passing slideway, platform below installed thrust oil cylinder, reverse wheel B are installed the below and are passed oil cylinder.Mine chain-bucket hoist need to carry out round-link chain when lax, and round-link chain remains static, and starts to pass oil cylinder reverse wheel B is moved to reverse wheel A direction along passing slideway, until two reverse wheel gears engagements.Start push action cylinder, utilize the linkage on the platform, platform is lifted.When lifting platform, round-link chain on the reverse wheel 1 is down sliding under action of gravitation, round-link chain drives reverse wheel A and rotates, this moment, the gear of reverse wheel A and reverse wheel B meshed, reverse wheel B also rotates together, when the round-link chain on the reverse wheel A was tightened, the round-link chain on the reverse wheel B relaxed because of the rotation of reverse wheel B.This moment, the round-link chain two ends were fixed, and lax state makes things convenient for the workman to keep in repair.After maintenance is finished, start push action cylinder and make platform drop to initial position, restart the passing oil cylinder and make reverse wheel B get back to initial position along passing slideway, just can start mine chain-bucket hoist and carry out work.
The invention has the beneficial effects as follows that guarantee the safe in operation of mine chain-bucket hoist when carrying out the lax maintenance of round-link chain, this device is simple to operate, does not need special tool, reduced the time that the lax maintenance of round-link chain consumes.
Description of drawings
Fig. 1 is the structural representation of embodiments of the invention.
The specific embodiment
As seen from Figure 1, the present invention includes and comprise platform (1), reverse wheel A (2), reverse wheel B (3) passes slideway (4), passes oil cylinder (5) and push action cylinder (6).Reverse wheel A (2) and reverse wheel B (3) are installed on the platform (1), reverse wheel B (3) is installed on the platform (1) by passing slideway (4), platform (1) below installed thrust oil cylinder (6), reverse wheel B (3) are installed the below and are passed oil cylinder (5).Mine chain-bucket hoist need to carry out round-link chain (7) when lax, round-link chain (7) remains static, start passing oil cylinder (5) reverse wheel B (3) is moved to reverse wheel A (2) direction along passing slideway (4), until two reverse wheel gears engagements.Start push action cylinder (6), utilize the linkage on the platform (1), platform (1) is lifted 3 ° to 5 °.When lifting platform (1), round-link chain (7) down sliding under action of gravitation on the reverse wheel A (2), round-link chain (7) drives reverse wheel A (2) and rotates, this moment, the gear of reverse wheel A (2) and reverse wheel B (3) meshed, reverse wheel B (3) also rotates together, round-link chain (7) on reverse wheel A (2) is when tightening, and the round-link chain (7) on the reverse wheel B (3) relaxes because of the rotation of reverse wheel B (3).This moment, round-link chain (7) two ends were fixed, and lax state makes things convenient for the workman to keep in repair.After maintenance is finished, start push action cylinder (6) and make platform (1) drop to initial position, restart the passing oil cylinder and make reverse wheel B (3) get back to initial position along passing slideway, just can start mine chain-bucket hoist and carry out work.
Claims (1)
1. the loosening maintenance device of a mine chain-bucket hoist round-link chain, it is characterized in that: reverse wheel A (2) and reverse wheel B (3) are arranged on the platform (1), reverse wheel B (3) is installed on the platform (1) by passing slideway (4), platform (1) below installed thrust oil cylinder (6), reverse wheel B (3) installs the below and passes oil cylinder (5), during this device work, round-link chain (7) remains static, starting passing oil cylinder (5) makes reverse wheel B (3) move to reverse wheel A (2) direction along passing slideway (4), until two reverse wheel gear engagements, start push action cylinder (6), utilize the linkage on the platform (1), platform (1) is lifted, round-link chain (7) down sliding on the reverse wheel A (2) drives simultaneously reverse wheel A (2) and rotates, reverse wheel A (2) and reverse wheel B (3) rotate together, upward round-link chain (7) is when tightening as reverse wheel A (2), and the round-link chain (7) on the reverse wheel B (3) just reaches relaxed state.
