Detailed Description

The following further describes embodiments of the present invention with reference to the drawings. It should be noted that the description of the embodiments is provided to help understanding of the present invention, but the present invention is not limited thereto. In addition, the technical features involved in the embodiments of the present invention described below may be combined with each other as long as they do not conflict with each other.

As shown in fig. 1, the chain bucket ship unloader mainly comprises a travelling portal frame 1, a rotary base 2, a belt conveyor 3, a balance beam 4, an obtuse angle component 8, an arm support 6, a central funnel 5, an oil cylinder 10 and a chain bucket lifting device 7.

The traveling portal frame 1 is provided with a rotary base 2 and an oil cylinder 10, an extending shaft of the oil cylinder 10 is connected with the front end section of the balance beam 4, and the arm support 6 is internally provided with the belt conveyor 3. The front end of the balance beam 4 is connected with an obtuse angle component with an included angle of 120 degrees, and the rear end of the balance beam 4 is provided with a balancing weight 11. The balance beam 4, the obtuse angle component 8, the arm support 6 and the rotary seat 2 form a four-bar linkage. The advancing portal frame 1 is provided with a central funnel 5, and a yard conveyor belt 9 is arranged below the central funnel 5. The obtuse angle member 8 hoists the bucket elevator 7.

As shown in fig. 2, the bucket elevator 7 comprises a housing 7.6 and a chain 7.1, the chain has an L-shaped path of motion, and correspondingly the housing has an L-shaped cavity. The chain 7.1 is provided with a plurality of chain buckets 7.2, the shell is provided with a firing prevention pin 7.3 and a cyclone separator 7.4, and the cyclone separator 7.4 is connected with the telescopic pipe 7.5. As shown in fig. 3, the striker 7.3 disposed at the corner of the L-shaped housing includes a probe 7.3a, the probe 7.3a is connected with a spring 7.3b, the spring 7.3b is mounted on an end seat 7.3c, the upper part and the lower part of the probe are respectively connected with a short-circuit switch through wires, and the short-circuit switch is electrically connected with the control center. Once the chain bucket lifting device is about to touch the bottom surface of the ship body, the anti-collision needle firstly touches the bottom surface of the ship body in the chain bucket lifting device, the short-circuit switch sends a signal to the control center, the lifting mechanism is immediately controlled to stop working, and the chain bucket lifting device is prevented from being damaged; even if the ship bottom contacts the anti-collision needle 7.3, under the action of the four-bar mechanism, the chain bucket lifting device can lift up naturally along with the ship bottom, so that hard impact cannot be formed, and damage to the ship bottom or material taking equipment cannot be caused.

The bucket ship unloader lifts bulk materials such as coal, iron ore and the like in a bulk cargo ship from a bulk cargo ship storage bin to a rotary feeding disc mechanism (not shown) on the obtuse angle member 8 through a chain which is arranged on a chain bucket lifting device in a reciprocating mode and a bucket chain thereof, and then conveys the materials to a central hopper 5 through a belt conveyor 3 by the rotary feeding disc mechanism until the materials are finally conveyed to a storage yard conveying belt 9, so that the whole unloading and conveying process is completed. When the ship is berthed and leaned on the shore, the advancing portal frame 1 reaches a position above a proper conveying belt 9, the rotary seat 3 works, and the balance beam 4 is adjusted to a corresponding angle until the chain bucket lifting device 7 is aligned to the position of the ship cabin; at the moment, the oil cylinder 10 works, the balance beam 4 drives the obtuse angle component 8 to fall, so that the bucket chain lifting device 7 is inserted into a cargo compartment of a cargo ship until the bucket chain lifting device 7 is contacted with the plane of the material; at the moment, the control center sends a signal, the chain bucket lifting device 7 starts to work, and materials are dug into the chain bucket from the warehouse under the driving of the chain wheel; then, the materials are lifted upwards to reach the top point, when the chain wheel changes the direction, the materials fall into the rotary material tray of the obtuse angle component 8 due to the dead weight of the materials, then the materials are sent to the conveying belt by the rotary material tray and conveyed to the central hopper by the belt conveyor until the materials are conveyed to the yard conveying belt, and the whole unloading and conveying process is completed.

The chain bucket lifting device has two working modes: 1. when the device normally works, the cyclone separator 7.4 is started to be in a low-power mode, the chain bucket 7.2 scrapes materials from a ship bin in the rotating process, the materials are lifted upwards and enter a rotary feeding disc mechanism (not shown) on the obtuse angle component 8 and then enter the belt conveyor, and meanwhile, the cyclone separator generates tiny negative pressure to absorb dust generated in the scraping operation and prevent the dust from scattering into the surrounding air; 2. when cabin bottom material layer thickness is less than 15 centimetres, because the chain bucket 7.2 is got the material and can rubs the cabin bottom, at this moment, cyclone 7.4 opens high-power mode, forms strong negative pressure, adsorbs the ship bottom residual material through flexible pipe 7.5, and the material gets into among the cyclone, carries out air and material separation, and the material falls to the chain bucket of chain bucket hoisting device through the dead weight in, until the material transport clean.

The embodiments of the present invention have been described in detail with reference to the accompanying drawings, but the present invention is not limited to the described embodiments. It will be apparent to those skilled in the art that various changes, modifications, substitutions and alterations can be made in these embodiments without departing from the principles and spirit of the invention, and the scope of protection is still within the scope of the invention.
