Description

Technical Field

[0001] The present invention relates to the technical field of bulk cargo transfer equipment, and particularly to a direct unloading type loading machine for bulk materials. Background Art

[0002] Bulk granular materials such as coal and iron ore are important raw materials for the economic development of our country. These bulk materials are usually first stacked in some transfer centers and then transported to various places by railway. In this process, it is necessary to load the bulk goods unloaded at the transfer center into the train carriage. There are the following common loading methods for bulk materials at existing docks:

[0003] (1) Feeding by dump truck and loading with a loader: The dump truck transports the bulk materials from the storage yard to a temporary storage beside the train line, and the loader scoops up the materials and dumps them into the train carriage. The advantage of this loading method is that the equipment and operation method are simple and convenient, and the requirements for the site and investment are low. However, the disadvantages are also obvious. This loading method adopts an intermittent relay type loading method, and the loading efficiency is relatively low compared with other loading methods. In addition, the dust pollution is serious during the operation process, and the cargo damage rate is relatively high.

[0004] (2) Direct dumping and loading by a fixed platform dump truck: A simple special loading platform is built beside the transportation railway line, and the height is basically flush with the top of the carriage. The dump truck drives onto the platform and directly dumps the materials into the carriage. The advantage of this loading method is that the intermediate transfer link is removed, and the dump truck directly supplies materials to the carriage, which not only reduces the intermediate cargo damage but also improves the transfer efficiency. However, there are also inevitable defects. The platform is fixed, and a traction train is required to cooperate with the platform, and the driver needs to adjust the dump truck to cooperate with the platform. In this process, the equipment and time costs are inevitably increased, and the transfer efficiency is reduced.

[0005] (3) Loading with a belt conveyor and a mobile loading machine: The belt conveyor transports the materials to the receiving point on the mobile loading machine, and the cantilever belt conveyor on the mobile loading machine loads the materials into the train carriage. This loading method has the advantages of high efficiency, high precision, environmental protection, and good economy. However, in use, the length of the belt transmission mechanism is too long, the floor area is too large, which seriously occupies the dock operation area and is prone to interference with other equipment, and it is difficult to be popularized and used in small and medium-sized docks.

[0006] (4) Loading with a system belt conveyor and a loading building: The system belt conveyor transports the bulk materials from the storage yard to the loading building, and the loading building loads the bulk materials into the train carriage. As a semi-automatic train loading method, this loading method can quickly and continuously load solid materials into a train traveling at a certain speed according to a preset loading quantity value, with high loading efficiency and low pollution. However, the construction and maintenance costs of the loading equipment are high, and the energy consumption during use is large.

[0007] The above four bulk material loading methods all have their own advantages and disadvantages, and have all been applied in the process of bulk cargo transportation at the wharf. Moreover, for small and medium-sized transfer centers with general volume and economic strength, they cannot afford the cost of building and using system belt conveyors and their supporting equipment, nor the space to accommodate belt pulleys. Some small and medium-sized transfer centers in the market need a bulk cargo conveying equipment with excellent comprehensive performance. Summary of the Invention

[0008] In view of this, it is necessary to provide a direct unloading loading machine for bulk materials, which can convey dump trucks and bulk materials at the same time, so as to solve the problem of the poor comprehensive performance of existing bulk cargo loading equipment.

A plurality of the guiding sleeves with openings facing outwards are sleeved on the guiding columns to position and guide the first vehicle-carrying plate.

[0012] Further, the first driving unit includes a first driving member and a traction member. Two ends of the traction member are respectively connected to the first car-carrying plate and the first driving member. The first driving member is fixedly connected to the loading machine body.

[0013] Further, the rotating assembly includes a gear ring and a second driving unit. The end face of the gear ring is fixedly connected to the bottom surface of the second car-carrying plate. The second driving unit includes a second driving member and a transmission gear. The second driving member is fixedly connected to the first car-carrying plate. The output end of the second driving member is connected to the transmission gear. The transmission gear meshes with the gear ring, so as to drive the second car-carrying plate to rotate relative to the first car-carrying plate, thereby driving the third car-carrying plate to rotate.

[0014] Further, the axis of the second driving member is arranged parallel to the first car-carrying plate. The transmission gear coaxially arranged with the second driving member and the gear ring are in bevel gear transmission.

[0015] Further, the second car-carrying plate includes two parallel baffles and a bottom plate fixedly connected to the two baffles. A chute is formed between the two outwardly protruding baffles and the bottom plate. The third car-carrying plate is embedded in the chute and is slidably connected to the chute.

Detailed implementation manners

[0032] The following will specifically describe the preferred embodiments of the present invention with reference to the accompanying drawings. The accompanying drawings form a part of this application and are used together with the embodiments of the present invention to explain the principles of the present invention, rather than to limit the scope of the present invention.

[0033] Refer to Figure 1 and Figure 2, A direct unloading loading machine for bulk materials in this embodiment includes a loading machine track 900 provided on one side of the track of the train to be loaded, a loading machine body 100 that can slide along the loading machine track 900, and a carrier platform 200 movably connected to the loading machine body 100. The track of the train to be loaded carries a freight train. The loading machine body 100 is a frame structure composed of steel profiles. Track wheels are provided at the bottom of the loading machine body 100, and the track wheels are fitted and installed on the loading machine track 900. The loading machine track 900 can be designed and installed independently or utilize the existing track of the train to be loaded. The loading machine body 100 can move on the loading machine track 900 under the traction of a driving device to achieve staying and working on the sides of different freight carriages of the same train. In the specific implementation process, generally, a motor and a transmission system are added to the base of the loading machine body 100 to drive the track wheels to rotate and lock themselves, so as to drive the movement and stop of the loading machine body 100. At the same time, as a simpler implementation method, an existing track traction vehicle can also be directly used to tow and lock the loading machine body 100 to achieve loading of different carriages of the same train linearly arranged on the track of the train to be loaded. The carrier platform 200 is movably arranged in the loading machine body 100. An elevating assembly 300 for driving the carrier platform 200 to move up and down is provided between the loading machine body 100 and the carrier platform 200. The elevating assembly 300 lifts the carrier platform 200 and the dump truck loaded with bulk materials to a height higher than the freight carriage, and this height is generally greater than 3.5 m. At the same time, when all the bulk materials are unloaded from the dump truck, the elevating assembly 300 smoothly lowers the carrier platform 200 and the empty dump truck. The carrier platform 200 is a multi-layer composite structure. The carrier platform 200 includes a third carrier plate 210 for carrying the dump truck, a rotating assembly 400, and a translation assembly 500. The rotating assembly 400 can drive the third carrier plate 210 to rotate 90°, so that the rear of the vehicle faces the freight carriage, facilitating the pouring of bulk materials, reducing the time required for the dump truck driver to adjust the vehicle posture, improving the efficiency, and also reducing potential safety hazards. The translation assembly 500 can move the entire third carrier plate 210 in a direction perpendicular to the length direction of the train, enabling the third carrier plate 210 to move above multiple tracks of the trains to be loaded, thereby performing loading operations on the carriages of multiple trains arranged side by side and increasing the working range of a single transfer platform. A direct unloading loading machine for bulk materials in the present invention, with the loading machine body 100 as the frame and the carrier platform 200 as the main body, through the coordinated use of the elevating assembly 300, the rotating assembly 400, and the translation assembly 500, achieves the purpose of changing the height of the dump truck, the orientation of the rear of the vehicle, and the relative position across the track of the train to be loaded, thereby improving the efficiency of transporting bulk materials using a dump truck.

[0034] Refer to Figures 2 to 4, the vehicle-carrying platform 200 includes a first vehicle-carrying plate 230, a second vehicle-carrying plate 220 arranged successively from bottom to top. The third vehicle-carrying plate 210 is arranged above the second vehicle-carrying plate 220. In a specific implementation, the second vehicle-carrying plate 220 is embedded in the first vehicle-carrying plate 230, and the third vehicle-carrying plate 210 is embedded in the second vehicle-carrying plate 220. The rotating assembly 400 is arranged between the first vehicle-carrying plate 230 and the second vehicle-carrying plate 220. The second vehicle-carrying plate 220 is rotatably connected to the first vehicle-carrying plate 230. The rotating assembly 400 drives the rotation of the second vehicle-carrying plate 220 relative to the first vehicle-carrying plate 230. The edge of the second vehicle-carrying plate 220 is designed to be smooth to prevent the second vehicle-carrying plate 220 from interfering with the first vehicle-carrying plate 230. The third vehicle-carrying plate 210 is slidably connected to the second vehicle-carrying plate 220. The translation assembly 500 is arranged on the second vehicle-carrying plate 220. The translation assembly 500 drives the third vehicle-carrying plate 210 to move along the length direction of the second vehicle-carrying plate 220. A blocking block or a blocking rope is arranged on the third vehicle-carrying plate 210 to lock the wheels of the dump truck and avoid the natural sliding of the dump truck on the third vehicle-carrying plate 210, reducing potential safety hazards.

[0035] Refer to Figure 5 and Figure 6, the lifting assembly 300 includes a first guiding unit 320 and a first driving unit 310. The outer edge of the first car carrier plate 230 is slidably connected to the loading machine body 100 through the first guiding unit 320. The first guiding unit 320 includes guiding columns 321 and guiding sleeves 322. The guiding columns 321 are fixedly connected to the loading machine body 100 as a part of the loading machine body 100. In the specific implementation process, the guiding columns 321 can be standard square profiles. A plurality of guiding columns 321 are evenly distributed outside the first car carrier plate 230. The guiding sleeves 322 are embedded in the edge of the first car carrier plate 230. The guiding sleeves 322 are semi-surrounding structures. A plurality of guiding sleeves 322 with openings facing outwards are sleeved on the guiding columns 321. The guiding columns 321 and the guiding sleeves 322 are cooperatively installed to position and guide the first car carrier plate 230. The first guiding unit 320 is used to limit the direction of the first car carrier plate 230 and reduce the shaking of the first car carrier plate 230 during the lifting and lowering processes. The first driving unit 310 includes a first driving member 311 and a traction member 312. The two ends of the traction member 312 are respectively connected to the first car carrier plate 230 and the first driving member 311. The driving member drives the first car carrier plate 230 to move up and down through the traction member 312. The first car carrier plate 230 bears the weight of the entire car carrier platform 200, as well as the weight of the dump truck and the bulk materials. The first driving unit 310 provides the power for the lifting of the first car carrier plate 230. In the specific implementation, the lifting of the first car carrier plate 230 can be achieved through a pulley group. Movable pulleys fixedly connected to the first car carrier plate 230 are provided at the four corners of the first car carrier plate 230. As one of the implementation manners, the traction member 312 is a steel wire rope. One end of the steel wire rope is fixedly connected to the loading machine body 100. The other end of the steel wire rope respectively passes through the movable pulleys and is connected to the first driving member 311. The first driving member 311 is a motor. The steel wire rope is sleeved in the pulley groove of the movable pulley. The first driving member 311 winds and unwinds the steel wire rope to realize the lifting of the first car carrier plate 230. As a further embodiment, the first driving member 311 can be used in cooperation with a roller and a counterweight. The output end of the first driving member 311 is connected to the roller. The steel wire rope is wound around the roller and leads out a free end fixedly connected to the counterweight. The rotation of the roller drives one end of the steel wire rope to shorten and the other end to elongate. The setting of the counterweight can balance the weight of the car carrier platform 200, thereby reducing the torque required for the motor to work and increasing the service life of the motor. And, the weight of the corresponding counterweight can be matched according to the weight of the dump truck and the bulk materials. As another implementation manner, the lifting of the first car carrier plate 230 can be realized by using a hydraulic system. The first driving member 311 is a hydraulic cylinder. The traction member 312 is a hydraulic rod. A plurality of hydraulic cylinders are used in cooperation with the hydraulic rods. A plurality of hydraulic rods are fixedly connected to the bottom of the first car carrier plate 230. The lifting of the hydraulic cylinders drives the lifting of the first car carrier plate 230, thereby realizing the lifting of the dump truck.

[0036] Continue to refer to Figures 2 to 4, the rotating assembly 400 includes a gear ring 410 and a second driving unit 420. The end face of the gear ring 410 is fixedly connected to the bottom surface of the second carrier plate 220. The second driving unit 420 includes a second driving member 421 and a transmission gear 422. The second driving member 421 is specifically a stepping motor. The second driving member 421 is embedded in the first carrier plate 230 and fixedly connected to the first carrier plate 230. The output end of the second driving member 421 is fixedly connected to the transmission gear 422. The second driving member 421 drives the transmission gear 422 to rotate coaxially. The transmission gear 422 meshes with the gear ring 410, and the transmission gear 422 drives the gear ring 410 to rotate relatively, thereby driving the second carrier plate 220 fixedly connected to the gear ring 410 to rotate relative to the first carrier plate 230. In actual arrangement, the axis of the second driving member 421 is arranged parallel to the first carrier plate 230, which can reduce the thickness of the second carrier plate 220 and is more convenient and reasonable in actual use. The transmission between the transmission gear 422 and the gear ring 410 is a bevel gear transmission. The bevel gear can achieve the cross-axis transmission between the second driving member 421 and the gear ring 410, better meet the requirements of the transmission direction and transmission efficiency between gear teeth, and has higher practicability.

[0037] Continue to refer to Figures 2 to 4 , the second carrier plate 220 includes two parallel baffles 221 and a bottom plate 222 fixedly connected to the two baffles. A chute 223 is formed between the two outwardly protruding baffles and the bottom plate. The third carrier plate 210 is embedded in the chute 223 and slidably connected to the chute 223. In the specific implementation process, the bottom plate 222 is provided with a hollow structure, which can not only create an installation space for components such as the second driving member 421, but also reduce the weight of the second carrier plate 220. The translation assembly includes a plurality of guiding members 510 and a third driving unit 520. The guiding members 510 are guide wheels. The plurality of guiding members 510 are linearly arranged inside the baffle 221. The bottom surface of the third carrier plate 210 is in rolling connection with the guiding members 510. The third driving unit 520 drives the third carrier plate 210 to slide relative to the second carrier plate 220 in the chute 223. The guiding members 510 can reduce the friction between the third carrier plate 210 and the second carrier plate 220 and make the parallel movement smoother. In the specific implementation process, the third driving unit 520 can be installed between the second carrier plate 220 and the third carrier plate 210. The third driving unit 520 is specifically a gear-rack mechanism cooperating with a motor. The gear is fixedly connected to the motor, and the rack is connected to the third carrier plate 210. The motor drives the gear-rack mechanism to move, thereby driving the third carrier plate 210 to move parallel to the second carrier plate 220.

[0038] Refer to Figures 5 to 7, at the top of the loading machine body 100, there is a side frame body 600 vertically arranged relative to the loading machine body 100. The side frame body 600 is of a frame structure. The side frame body 600 includes a discharge guide frame 620 and a counterweight frame 610. The discharge guide frame 620 and the counterweight frame 610 are respectively arranged on both sides of the loading machine body 100. The counterweight frame 610 is provided with counterweight blocks to balance the weight in the discharge guide frame 620 and prevent the overall side overturning of the loading machine body 100 due to excessive unilateral weight of the discharge guide frame 620. The discharge guide frame 620 can span multiple tracks of the trains to be loaded, realizing the bulk cargo loading of the carriages of multiple trains arranged side by side. On both sides of the discharge guide frame 620 symmetrically in the moving direction, there are guide rails 621. Inside a section of the guide rail 621 close to the car-carrying platform 200, there is an auxiliary guiding member 622, and the auxiliary guiding member 622 is an auxiliary guide wheel. During the process of the third car-carrying plate 210 extending out of the loading machine body 100, the extending section of the third car-carrying plate 210 is in rolling connection with the auxiliary guiding member 622. In the specific implementation process, multiple auxiliary guiding members 622 are arranged below the inner sides of the two symmetrically arranged guide rails 621. The bottom sides of both sides of the third car-carrying plate 210 that extends and moves horizontally are in rolling connection with the auxiliary guiding members 622. The auxiliary guiding members 622 bear the load on the third car-carrying plate 210, reducing the sliding resistance of the third car-carrying plate 210 and making the parallel movement more stable and smooth.

[0039] Continue to refer to Figures 5 to 7 , a discharge hopper 700 is slidably connected to the guide rail 621. The upper part of the discharge hopper 700 is detachably installed with the car body of the dump truck. When the car body of the dump truck dumps the goods with the hopper tilted downward, the discharge opening of the hopper is docked with the discharge hopper 700, and the goods in the hopper enter the train carriage after passing through the discharge hopper 700. A dust-proof structure 710 for reducing dust is provided on the discharge hopper 700, which can effectively reduce the dust generated during the pouring process of bulk materials such as coal and stone. A material guiding channel 720 is provided at the lower part of the discharge hopper 700. The material guiding channel 720 guides the bulk cargo into the train carriage through a funnel-shaped structure, improving the situation that the bulk cargo overflows from the train carriage during unloading. On both sides of the loading machine body 100, there are inclined guide frames 800. The inclined guide frames 800 are inclined between the loading machine body 100 and the loading machine track 900. One end of the inclined guide frame 800 is detachably hinged to the loading machine body 100, and the other end of the inclined guide frame 800 is slidably connected to the loading machine track 900. The dump truck can conveniently enter and exit the loading machine body 100 along the inclined guide frame 800, bringing convenience to the use of the loading machine body 100.

[0040] Workflow: Before use, the car-carrying platform 200 is located below the loading machine body 100. The second car-carrying plate 220 is arranged parallel to the length direction of the first car-carrying plate 230. The third car-carrying plate 210 is retracted into the second car-carrying plate 220. The dump truck full of bulk goods drives onto the third car-carrying plate 210 by using the inclined guide frame 800 and is locked to restrict movement. First, start the lifting assembly 300 to lift the dump truck to a height position flush with the guide rail 621 by lifting the car-carrying platform 200. Then start the rotating assembly 400 to drive the second car-carrying plate 220 to rotate 90°, thereby turning the rear of the dump truck by 90° so that the rear is facing the train carriage directly. Connect the mobile unloading hopper 700 to the third car-carrying plate 210. Next, start the translation assembly 500 to drive the third car-carrying plate 210 to extend along the direction of the guide rail 621 to directly above the carriage of any one of the multi-row parallel trains as required. Control the hopper of the dump truck to tilt through the hydraulic system of the dump truck to unload the bulk materials. Immediately afterwards, use the translation assembly 500 to drive the third car-carrying plate 210 to retract along the direction of the guide rail 621 onto the second car-carrying plate 220, thereby driving the dump truck back onto the car-carrying platform 200, disconnect the mobile unloading hopper 700 from the third car-carrying plate 210, and use the rotating assembly 400 to drive the second car-carrying plate 220 to rotate 90° in the reverse direction to restore the rear direction of the dump truck. Finally, use the lifting assembly 300 to drive the first car-carrying plate 230 to lower to the original height, release the lock on the dump truck, start the dump truck, and drive out of the loading machine body 100 through another inclined guide frame 800 to complete the unloading process of one dump truck. When one carriage of the same train is full, the loading machine body 100 can be driven to move as a whole along the loading machine track 900 to the side of another carriage to load another train carriage. By repeating this cycle, the loading task for multiple trains can be completed.

[0041] As described above, it is only the preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any changes or substitutions that can be easily thought of by those skilled in the art within the technical scope disclosed by the present invention should be covered by the present invention.
