Description

Technical Field

[0001] The present invention relates to the field of ship unloading equipment at port terminals, and in particular to a cross-retractable multi-point feeding system of a ship unloader. Background Art

[0002] The grab ship unloader is the core equipment for the mechanized unloading of bulk cargo at port terminals. It grabs materials from the ship's hold through a grab bucket, transfers them multiple times through the hopper and feeding conveying system, and finally unloads the materials onto the terminal's belt conveyor. It is a key link in the transportation chain connecting the ship's hold and the terminal.

[0003] With the large-scale development of ports, modern large-scale terminals generally arrange multiple parallel or staggered conveyor belts to improve loading and unloading efficiency. However, the rotary feeding system used by traditional ship unloaders has significant limitations: due to the large rotation radius and limited feeding range, it cannot effectively cover the feeding needs of multiple conveyor belts, resulting in low equipment utilization and difficulty in improving operating efficiency. At the same time, terminal conveyor belts are equipped with sealed cover belts to prevent dust from escaping. During the feeding and switching process of multiple conveyor belts, the presence of the cover belts will interfere with the unloading process. If the cover belts are forcibly opened for unloading, dust will easily fly, violating environmental protection requirements; if the cover belts are kept closed, accurate unloading cannot be achieved, forming a contradiction between "unloading and sealing".

[0004] Therefore, how to use a feeding belt conveyor to achieve accurate unloading of conveyor belts at different terminals, while ensuring that the cover belt on each conveyor belt runs smoothly and remains sealed to prevent dust from overflowing has become a technical problem that needs to be solved urgently. Summary of the Invention

[0005] In response to the above technical problems, a cross-retractable multi-point feeding system for a ship unloader is provided. The present invention realizes multi-point sealed feeding of the ship unloader to multiple conveyor belts at the dock by cross-arranged belt feeders, retractable conveyors and dock cover belt opening and closing devices.

[0006] To achieve the above object, the present invention provides a cross-retractable multi-point feeding system for a ship unloader, comprising a belt feeder, a telescopic conveyor, a dock cover belt opening and closing device, and a dock fixed chute; The belt feeder is used to continuously receive materials from the hopper and output them evenly; The telescopic conveyor is arranged below the belt feeder, is used to receive the materials output by the belt feeder, and can move forward and backward along the gantry track; The dock cover belt opening and closing device is fixedly mounted on the ship unloader frame and is used to control the opening and closing of the dock conveyor belt cover; The dock fixed chute is arranged below the ship unloader frame and is used to receive the materials output by the telescopic conveyor and transport them evenly to the dock conveyor belt.

[0009] Furthermore, the telescopic drive includes a redirecting pulley, a retracting wire rope, an extending wire rope, and a drum; The redirecting pulleys are fixedly mounted on both sides of the gantry track; The retracting steel wire rope is divided into two upper and lower parts, one end of which is fixed on the supporting wheel and the other end is wound on the drum; the extending steel wire rope is divided into two upper and lower parts, one end of each steel wire rope is fixed on the discharge port and the other end is wound on the drum; the drum is fixedly mounted on the door frame through the bearing seat and is connected to the driving reducer through the coupling; wherein, when the drum rotates clockwise, it drives the telescopic frame to move right, and when it rotates counterclockwise, it drives the telescopic frame to move left.

[0010] Furthermore, the dock cover belt opening and closing device includes a support frame, an upper redirecting roller, and a lower belt pressing roller; The support frame is in a gate-shaped structure, and the telescopic conveyor can move inside it; the upper redirecting roller is fixedly installed above the support frame and is used to lift the cover belt; the lower belt pressing roller is fixedly installed below the support frame and is used to press the cover belt onto the terminal conveyor belt.

[0011] Furthermore, the number of the fixed chutes at the terminal corresponds to the number of the conveyor belts at the terminal, and is used to receive the materials from the telescopic conveyor and evenly transport them to the conveyor belts at the terminal.

[0026] like Figures 1 to 9 As shown, the present invention provides a cross-retractable multi-point feeding system for a ship unloader, comprising a belt feeder 1, a telescopic conveyor 2, a dock cover belt opening and closing device 3, and a dock fixed chute 4; The belt feeder 1 is installed on the ship unloader frame 6 and is used to continuously receive materials from the hopper 5 and output them evenly; the telescopic conveyor 2 is arranged below the belt feeder 1, and is used to receive materials output by the belt feeder 1, and can move back and forth along the gantry track; the dock cover belt opening and closing device 3 is fixedly installed on the ship unloader frame 6, and is used to control the opening and closing of the cover belt 7 of the dock conveyor belt; the dock fixed chute 4 is arranged below the ship unloader frame 6, and is used to receive materials output by the telescopic conveyor 2 and transport them evenly to the dock conveyor belt.

[0027] Furthermore, the belt feeder 1 comprises: a fixed frame 11, a belt feeding roller 12, a sealed guide trough 13, a throwing trough 14, and a lower guide trough 15; The fixed frame 11 is fixedly mounted on the ship unloader frame 6; the belt feeding rollers 12 are evenly distributed and mounted above the fixed frame 11, and the rollers on both sides have an upward inclination; the sealed material guide trough 13 is fixedly mounted on both sides of the belt feeding rollers 12; the throwing trough 14 is fixedly mounted on the front end of the fixed frame 11 and docked with the outlet of the sealed material guide trough 13; the lower material guide trough 15 is mounted below the throwing trough 14 and is used to transport the material to the telescopic conveyor 2. The material leakage is prevented by tilting the rollers, and the sealed material guide trough 13 and the throwing trough 14 realize closed transportation. The lower material guide trough 15 ensures uniform material flow, solves the problems of leakage and dust during material transportation, and realizes uniform and environmentally friendly output of materials.

[0028] Furthermore, the telescopic conveyor 2 includes: a telescopic frame 21, a telescopic roller group 22, a discharge port 23, and a telescopic drive 25; The telescopic frame 21 is mounted on the ship unloader frame 6 through the support wheel 24. The telescopic roller group 22 is evenly installed above the telescopic frame 21 and is provided with a first buffer roller 221, a second buffer roller 222, and a third buffer roller 223. The discharge port 23 is fixedly installed at the front end of the telescopic frame 21. The telescopic drive 25 is used to drive the telescopic frame 21 to move telescopically along the track. The buffer roller provides support at different telescopic positions to ensure smooth transportation of materials during the telescopic process. The support wheel 24 cooperates with the telescopic drive 25 to achieve movement, meet the feeding requirements of different conveyor belts, and solve the problems of material bumps and unstable transportation during the telescopic process.

[0029] Furthermore, the telescopic drive 25 includes a redirecting pulley 251, a retracting wire rope 252, an extending wire rope 257, and a drum 254; The redirecting pulley 251 is fixedly mounted on both sides of the gantry track, and the retracted wire rope 252 is divided into two upper and lower parts, one end of which is fixed on the support wheel 24 and the other end is wound on the drum 254. The extended wire rope 257 is divided into two upper and lower parts, one end of each wire rope is fixed on the discharge port 23, and the other end is wound on the drum 254. The drum 254 is fixedly mounted on the gantry through the bearing seat 253 and is connected to the driving reducer 256 through the coupling 255. When the drum 254 rotates clockwise, it drives the telescopic frame 21 to move right, and when it rotates counterclockwise, it drives the telescopic frame 21 to move left. Through the cooperation of the wire rope and the drum 254, the telescopic frame 21 can be moved accurately and smoothly, which solves the problem that the conventional feeding device cannot flexibly switch the conveyor belt, and realizes the precise control of multi-point feeding.

[0030] Furthermore, the dock cover belt opening and closing device 3 includes a support frame 31, an upper redirecting roller 32, and a lower belt pressing roller 33; The support frame 31 has a gate-shaped structure, and the telescopic conveyor 2 can move inside it. The upper redirecting roller 32 is fixedly installed above the support frame 31 and is used to lift the cover belt 7. The lower pressing roller 33 is fixedly installed below the support frame 31 and is used to press the cover belt 7 onto the terminal conveyor belt. The gate-shaped support frame 31 allows the telescopic conveyor 2 to shuttle, the upper roller lifts the cover belt 7 to ensure feeding space, and the lower roller presses the cover belt 7 back to achieve sealing, which solves the problem of the cover belt 7 hindering feeding, prevents dust from overflowing, and achieves environmentally friendly sealing.

[0031] Furthermore, the number of the fixed chutes 4 at the terminal corresponds to the number of conveyor belts at the terminal, which are used to receive the materials from the telescopic conveyor 2 and transport them evenly to the conveyor belts at the terminal. The number of chutes corresponds to the number of conveyor belts, realizing the precise distribution of materials to each conveyor belt, solving the problem of uneven material distribution during multi-point feeding, and ensuring the feeding stability of each conveyor belt.

[0032] Furthermore, the belt feeder 1 and the telescopic conveyor 2 are arranged in a cross pattern. The cross pattern realizes a 90° change in the material conveying direction, meeting the requirements of the horizontal layout of multiple conveyor belts at the terminal. Conventional rotary feeders cannot cover the material due to their large radius, thus solving the space limitation problem of feeding from multiple conveyor belts and expanding the feeding coverage.

[0033] The implementation steps of this device: The material grabbed by the grab ship unloader is first stored in the hopper 5. The material in the hopper 5 enters the belt feeder 1. The belt feeder 1 is fixed to the ship unloader frame 6 via a fixed frame 11. The belt feeder rollers 12 evenly distributed above it convey the material smoothly. The sealed material guide troughs 13 on both sides seal the material conveying area to prevent leakage and dust. The material enters the connected throwing chute 14 through the outlet of the sealed material guide trough 13. Then, it is conveyed to the telescopic conveyor 2 through the lower material guide trough 15 below the throwing chute 14 with a fixed material flow cross section. After the telescopic conveyor 2 receives the material from the lower guide trough 15, the material is conveyed to the front end discharge port 23 through the telescopic roller group 22 above the telescopic frame 21, with buffer rollers arranged at specific positions to adapt to different telescopic positions; the telescopic frame 21 carries the weight through the support wheel 24 and moves along the gantry track, and its telescopic action is realized by the telescopic drive 25; the redirection pulley 251 adjusts the direction of the wire rope, retracts the wire rope 252, fixes one end of the support wheel 24, and winds the other end around the drum 254, and extends the wire rope 252. One end of 57 is fixed with the discharge port 23, and the other end is wound around the reel 254, driving the reducer 256 to rotate the reel 254 through the coupling 255. When rotating clockwise, the steel wire rope 257 is extended to collect the rope and the steel wire rope 252 is retracted to release the rope, driving the telescopic frame 21 to move rightward; when rotating counterclockwise, the steel wire rope 252 is retracted to collect the rope and the steel wire rope 257 is extended to release the rope, driving the telescopic frame 21 to move leftward, thereby realizing the telescopic conveyor 2 to extend and retract along the track, corresponding to the position of the conveyor belt at different terminals; During the movement of the telescopic conveyor 2, the terminal cover belt opening and closing device 3 works in conjunction with the telescopic conveyor 2; the gate-shaped support frame 31 allows the telescopic conveyor 2 to shuttle inside it. When the telescopic conveyor 2 moves to the target conveyor belt, the upper redirecting roller 32 lifts and opens the cover belt 7 above the terminal conveyor belt, making room for the discharge port 23 of the telescopic conveyor 2; when the telescopic conveyor 2 completes feeding at this position, the lower belt pressing roller 33 presses the cover belt 7 back onto the terminal conveyor belt to achieve a seal and prevent dust from escaping; The fixed chute 4 at the wharf receives the materials thrown out from the discharge port 23 by the telescopic conveyor 2 and evenly transports the materials to the corresponding wharf conveyor belt, completing the entire multi-point feeding process.

[0034] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present invention.
