Description

Technical Field

[0001] This utility model relates to the field of coke transportation technology, and in particular to a double-cone spiral scraper used when coke is loaded onto trucks quickly. Background Technology

[0002] When coke is transported by road, due to its inherent characteristics (such as rough surface, irregular block shape, and light weight), the coke surface in the truck bed is uneven after loading, exhibiting a high center and low sides. This is detrimental to improving truck loading efficiency and inconvenient for transportation, thus requiring leveling. Currently, leveling is mostly done manually or with scraper-type rigid leveling devices (such as the "Automobile Unloading Machine" disclosed in Chinese Utility Model Patent Publication No. CN2155360Y and the "Automatic Automobile Leveling Device" disclosed in Chinese Utility Model Patent Publication No. CN208345356U). Manually leveling the coke in the truck bed is not only labor-intensive but also inefficient. Leveling with scrapers or other rigid leveling devices easily causes coke to spill and break.

[0003] A newly developed rapid coke truck loading technology uses a belt conveyor to continuously feed coke from the coke bin into a buffer bin. A hydraulic gate is installed at the bottom outlet of the buffer bin. A pre-set loading quantity allows for rapid and quantitative unloading of coke onto a moving truck via the hydraulic gate and loading chute. For example, the "Intelligent Quantitative Unloading and Loading Device" disclosed in Chinese Utility Model Patent Publication No. CN 214827411 U utilizes a sliding frame and a leveling frame. When the auger rotates to discharge material, the sliding frame and leveling frame reciprocate, leveling the material accumulated at the bottom of the discharge pipe, preventing raw material buildup, and improving the safety of the device.

[0004] The leveling device used for rapid loading of coke onto trucks has the following problems:

[0005] 1) The loading speed of coke trucks is fast and is completed while the truck is in motion. Because coke is light and has a rough surface, using hard scraping devices such as scrapers can easily cause coke to splatter and spill, and the coke can also be damaged due to compression.

[0006] 2) During rapid loading of coke into trucks, the loading and leveling processes occur simultaneously. Leveling is completed at the same time as loading, and weighing is finished on the truck scale. To avoid secondary unloading after overloading, negative tolerances are often used during rapid loading of coke into trucks. A small amount of coke is added after loading to reach the predetermined load. However, this small amount of added coke tends to scatter on top of the already leveled coke layer in the truck bed, making it prone to spillage and hindering further sealing. Summary of the Invention

[0007] This invention provides a double-cone spiral scraper for rapid loading of coke into trucks. It employs a double-cone spiral scraper structure that is thicker in the middle and thinner at both ends, effectively adapting to the material distribution characteristics during rapid loading of coke into trucks (the material surface is high at the initial loading point in the truck bed, gradually transitioning to lower levels on both sides), thus achieving rapid leveling of the coke surface within the truck bed. The conical spiral scraper avoids excessive cutting of the coke. By rationally matching the rotation speed of the conical spiral scraper with the truck's running speed during loading, it also achieves an effect of no moving friction between the coke and the conical spiral scraper along the vehicle's forward direction, thereby minimizing coke breakage during the scraping process.

[0008] To achieve the above objectives, the present invention adopts the following technical solution:

[0009] A double-cone spiral scraper for rapid loading of coke onto trucks includes a hanger, an electro-hydraulic actuator, and a double-cone spiral scraper assembly. The double-cone spiral scraper assembly consists of a central housing, a plowing head, conical spiral scrapers, and a drive unit. The central housing is suspended below the crossbeam of the loading platform by the hanger. The top of the hanger is hinged to the crossbeam, and the middle of the hanger is hinged to the extended end of the electro-hydraulic actuator. Under the action of the electro-hydraulic actuator, the double-cone spiral scraper assembly can rotate around the top hinge point, thereby achieving lifting and lowering. The drive unit is located inside the central housing. A set of conical spiral scrapers is installed on each side of the central housing. The inner end of the conical spiral scraper is connected to the drive unit and can rotate around its axis under the drive unit's influence. The inner spiral diameter of the conical spiral scraper is larger than the outer spiral diameter. A plowing head is located at one end of the central housing, and the plowing head is a wedge-shaped structure protruding outwards from the center. The bottom surface of the plowing head and the bottom surface of the conical spiral scraper are on the same plane.

[0010] Furthermore, the drive device is a dual-output shaft geared motor.

[0011] Furthermore, the outer end of the conical spiral scraper is provided with a small conical spiral, the bottom surface of which is a plane and is lower than the bottom surface of the conical spiral scraper.

[0012] Furthermore, a lifting point is provided on the connecting shaft between the small conical spiral and the conical spiral scraper, and it is connected to the crossbeam of the loading platform through an auxiliary lifting cable.

[0013] A double-cone spiral scraper for rapid loading of coke onto trucks, further comprising a coke leveling control system; the coke leveling control system consists of a coke leveling main controller, a rangefinder, a speedometer, and limit switches; the rangefinder is located above the leveling head and is used to monitor the distance between the double-cone spiral scraper and the tailgate of the truck bed; the speedometer is located at the bottom of the coke hopper and is used to monitor the moving speed of the truck during loading; the limit switches are located outside the extended end of the electro-hydraulic actuator and are used to monitor the lifting height of the double-cone spiral scraper assembly; the signal output terminals of the rangefinder, speedometer, and limit switches are connected to the coke leveling main controller, and the control terminals of the drive device and the electro-hydraulic actuator are also connected to the coke leveling main controller; the coke leveling main controller is further connected to the main controller of the rapid loading system.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] 1) The double-conical spiral scraper structure with a thicker middle and thinner ends can adapt well to the material distribution characteristics when loading coke into trucks quickly (the material surface is high at the material drop point in the middle of the truck and gradually transitions to the lower part on both sides of the truck), thereby achieving rapid flattening of the coke material surface in the truck.

[0016] 2) The conical spiral scraper can avoid excessive cutting of coke. By reasonably matching the rotation speed of the conical spiral scraper with the running speed of the truck during loading, it can also achieve the effect of no moving friction between the coke and the conical spiral scraper along the direction of vehicle movement, which can minimize the damage to the coke caused by the leveling process.

[0017] 3) The double-cone spiral scraper assembly has a small conical spiral at the outer end of the conical spiral scraper. While scraping the coke, it opens a coke replenishment trough. After the coke is loaded and weighed, coke is replenished into the coke replenishment trough through the coke replenishment pipe. After the coke is replenished, the material surface in the car body remains flat, the replenished coke is not easy to spill, and it is also conducive to further sealing treatment.

[0023] The specific embodiments of this utility model will be further described below with reference to the accompanying drawings:

[0024] like Figures 1-3 As shown, a double-cone spiral scraper for rapid loading of coke onto trucks includes a hanger 2, an electro-hydraulic actuator 7, and a double-cone spiral scraper assembly 3. The double-cone spiral scraper assembly 3 consists of a central housing, a plowing head 31, a conical spiral scraper 33, and a drive device 32. The central housing is suspended below the crossbeam of the loading platform 1 by the hanger 2. The top of the hanger 2 is hinged to the crossbeam, and the middle of the hanger 2 is hinged to the extended end of the electro-hydraulic actuator 7. Under the action of the electro-hydraulic actuator 7, the double-cone spiral scraper assembly 3 can rotate as a whole around the top hinge. The contact point rotates, thereby realizing the lifting action; the driving device 32 is located in the middle box, and a set of conical spiral scrapers 33 are respectively set on both sides of the middle box. The inner end of the conical spiral scraper 33 is connected to the driving device 32 and can rotate around the axis under the drive of the driving device 32; the spiral diameter of the inner end of the conical spiral scraper 33 is larger than the spiral diameter of the outer end; a plowing head 31 is provided at one end of the middle box. The plowing head 31 is a wedge-shaped structure that protrudes outward from the middle; the bottom surface of the plowing head 31 and the bottom surface of the conical spiral scraper 33 are on the same plane.

[0025] Furthermore, the drive device 32 is a dual-output shaft geared motor.

[0026] Furthermore, the outer end of the conical spiral scraper 33 is also provided with a small conical spiral 34, the bottom surface of the small conical spiral 34 is a plane, and the bottom surface of the small conical spiral 34 is lower than the bottom surface of the conical spiral scraper 33.

[0027] Furthermore, a lifting point is provided on the connecting shaft between the small conical spiral 34 and the conical spiral scraper 33, and it is connected to the crossbeam of the loading platform 1 through the auxiliary lifting cable 4.

[0028] Furthermore, such as Figures 2-4As shown, the present invention provides a double-cone spiral scraper for rapid loading of coke onto trucks, which further includes a coke leveling control system. The coke leveling control system comprises a coke leveling main controller 10, a rangefinder 9, a speedometer, and a limit switch 8. The rangefinder 9 is located above the leveling head 31 and is used to monitor the distance between the double-cone spiral scraper and the rear deck of the truck 5. The speedometer is located at the bottom of the coke hopper 11 and is used to monitor the moving speed of the truck 5 during loading. The limit switch 8 is located outside the extended end of the electro-hydraulic push rod 7 and is used to monitor the lifting height of the double-cone spiral scraper assembly 3. The signal output terminals of the rangefinder 9, speedometer, and limit switch 8 are connected to the coke leveling main controller 10, and the control terminals of the drive device 32 and the electro-hydraulic push rod 7 are also connected to the coke leveling main controller 10. The coke leveling main controller 10 is also connected to the main controller of the rapid loading system.

[0029] The control method of the double-cone spiral scraper for rapid loading of coke into trucks according to this utility model is as follows:

[0030] 1) Before loading coke, the double-cone spiral scraper assembly 3 is in an initial position higher than the maximum height of the truck 5; the truck 5 drives to the initial coke receiving position below the coke silo 11;

[0031] 2) After the coke loading begins, the main controller of the rapid loading system sends the start signal of the coke discharge gate 11 to the coke leveling main controller 10; the coke leveling main controller 10 controls the electro-hydraulic push rod 7 to start, so that the double conical spiral scraper assembly 3 falls as a whole.

[0032] 3) After the double conical spiral scraper assembly 3 reaches the set scraping height, i.e. the lower limit position of the limit switch 8, the flat coke main controller 10 controls the electro-hydraulic push rod 7 to stop moving; at the same time, it controls the drive device 32 to start, driving the conical spiral scraper 33 and the small conical spiral 34 to rotate synchronously.

[0033] 4) The speed measuring instrument sends the monitored speed of the car 5 to the flat coking main controller 20. The flat coking main controller 20 adjusts the output speed of the drive device 32 according to the preset parameters, that is, adjusts the speed of the double conical spiral scraper 33 and the small conical spiral 34.

[0034] 5) During the loading process, the rangefinder 9 monitors the distance between the double-cone spiral leveling device and the tailboard of the car body in real time, and immediately feeds back to the leveling main controller 10 when the set value is reached.

[0035] 6) After receiving feedback from the rangefinder 9, the main controller 10 immediately controls the drive device 32 to stop operating and starts the electro-hydraulic push rod 7 to lift the double conical spiral scraper assembly 3 as a whole until it reaches the upper limit position of the limit switch 8, i.e., the initial position, and then stops; the coking operation during the loading process ends.

[0036] The double - conical spiral leveling device for rapid loading of coke trucks described in the utility model is a leveling device supporting the existing rapid loading system for coke trucks. The rapid loading system for coke trucks includes a coke bin 11, which is arranged on a loading platform 1. A coke discharge gate 12 is provided at the coke outlet at the bottom of the coke bin 11; the coke discharge gate 12 is connected to a lower coke discharge chute 13. After the coke discharge gate 12 is opened, the coke in the coke bin 11 enters the carriage of the truck 5 through the coke discharge chute 13; while discharging coke, the truck 5 moves at a constant speed, so that the coke is quantitatively and evenly distributed longitudinally into the carriage. The coke discharge chute 13 usually also has a chute angle adjustment device 14 to meet the requirements of different truck carriages and coke discharge heights.

[0037] Along the moving direction of the truck 5 during loading, the double - conical spiral leveling device described in the utility model is arranged at the bottom of the coke bin 11 and downstream of the coke discharge chute 13.

[0038] The double - conical spiral scraper assembly 3 is a symmetric structure. The middle box body is arranged at the lower end of the hanger 2, and a set of conical spiral scrapers 33 is symmetrically arranged on each side of the middle box body. The plow head 31 is arranged in front of the middle box body (in the direction facing the coke to be leveled). The inner end of the conical spiral scraper 33 is thick and the outer end is thin, and the bottom surface of the conical spiral scraper 33 is flush with the bottom surface of the plow head 31, so as to ensure that the coke surface after passing through the double - conical spiral scraper assembly 3 is a plane.

[0039] The driving device 32 is arranged in the middle box body behind the plow head 31. The driving device 32 is preferably a double - output - shaft reduction motor, and its two output shafts are respectively传动连接 with the corresponding conical spiral scrapers 33, which can ensure that the two conical spiral scrapers 33 rotate synchronously.

[0040] One end of the electro - hydraulic push rod 7 is fixed on the loading platform 1 below the coke bin 11, and the other end is hinged to the middle of the hanger 2. The top of the hanger 2 is hinged to the cross beam of the loading platform 1 through a bearing support. When the electro - hydraulic push rod 7 acts, the hanger 2 swings around the rotating shaft in the bearing support, and at the same time带动 the entire double - conical spiral scraper assembly 3 to rise and fall. The hanger 2 is preferably a telescopic sleeve structure with adjustable length.

[0041] The limit switch 8 is arranged outside the extended end of the hydraulic push rod 7. The distance measuring instrument 9 is installed above the plow head 31. The speed measuring instrument is installed at the bottom of the coke bin 11. The main controller 10 for leveling coke is located in the main control room of the rapid loading system. When controlling the leveling coke operation, the rotation speed of the conical spiral scraper 33 is positively correlated with the traveling speed of the truck 5 during loading.

[0042] Each of the outer ends of the conical spiral scraper 33 is equipped with a small conical spiral 34, which opens a coke replenishment trough while scraping the coke. After the coke is loaded and weighed, coke is replenished into the coke replenishment trough 34 through the coke replenishment pipe. After the coke is replenished, the material surface in the car body remains flat, the replenished coke is not easy to spill, and it is also conducive to further sealing treatment.

[0043] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and inventive concept of the present utility model, should be included within the protection scope of the present utility model.
