Technical Field

[0001] This invention belongs to the technical field of logistics loading and unloading equipment, specifically relating to a material loading and unloading system that can be used on electrified railway lines. Background Technology

[0002] Railway transportation has the advantages of long distance, large volume, and low cost. It uses train carriages to transport materials. In practice, it is often used to transport bulk materials such as coal and sand. However, the loading of coal into open wagons in the coal sheds of railway freight yards is mainly done by loader. This is affected by interference from the contact grid of the electrified railway line, the space is limited, the equipment needs to be operated carefully, the loading is inconvenient, and the loading and unloading of loaders generates a lot of dust, environmental problems and spillage cannot be avoided.

[0003] Therefore, how to provide a material handling and loading system that can be used on electrified railway lines is a problem that urgently needs to be solved by those skilled in the art. Summary of the Invention

[0004] In view of this, the present invention provides a material loading system that can be used on electrified railway lines, which can achieve material loading across carriages without spillage, while avoiding contact with the power grid of electrified lines, thereby improving loading safety and environmental protection.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a material handling and loading system applicable to electrified railway lines, comprising:

[0006] A mobile material handling machine, which is slidably mounted on ground rails on both sides of the yard and is capable of picking up materials from the yard; A transition conveyor unit is provided on the discharge path of the mobile reclaimer and is capable of transferring and conveying materials; The discharge belt conveyor is arranged parallel to the railway track and is used to receive the material sent by the transition conveyor unit. The frame of the discharge belt conveyor is provided with guide rails on both sides corresponding to the material conveying direction of the discharge belt conveyor. A mobile unloading vehicle travels on the guide rail and is located on the top side of the railway track car, avoiding the contact wire of the railway track. The mobile unloading vehicle is equipped with a receiving end and a double discharge end. A deflector roller is rotatably connected to the receiving end of the mobile unloading vehicle. The deflector roller is wound around the belt of the discharge conveyor and changes the direction of the belt's movement. The material of the discharge conveyor enters the receiving end after passing through the deflector roller. The double discharge ends are arranged in parallel at intervals and can connect to adjacent cars during the loading process.

[0007] The beneficial effects of this invention are as follows: a mobile reclaimer is used to retrieve materials from the stockyard or freight yard, and the materials are then transported to the discharge conveyor via a transition conveyor mechanism. Finally, a mobile unloading vehicle coupled to the discharge conveyor completes the discharge process. The mobile unloading vehicle is located on one side of the top of the truck body, which will not affect the existing electrical wiring or contact with the power grid, ensuring safe loading. The mobile unloading vehicle has two discharge ends, which can connect to adjacent truck bodies during the loading process without stopping the machine, making loading highly efficient.

[0008] Preferably, the mobile material handling machine includes a mobile gantry frame, a mobile trolley, a multi-joint screw material handling unit, and a horizontal feeding mechanism. The mobile gantry frame spans the yard, the mobile trolley is horizontally slidably mounted on the top of the mobile gantry frame, the multi-joint screw material handling unit is mounted on the mobile trolley and picks up materials when the mobile trolley moves to a different position, the horizontal feeding mechanism is located on the top side of the mobile gantry frame and can receive and transfer materials from the multi-joint screw material handling unit, and the transition conveyor is located on the discharge path at the discharge end of the horizontal feeding mechanism and can receive and transfer materials.

[0009] The resulting technical effects are: a wide range of material handling conditions are provided by the mobile gantry frame; the mobile trolley can carry the multi-joint screw feeder unit to handle material handling in different areas of the yard; the multi-joint screw feeder unit can adjust the material handling angle and can be folded up when not in use, so as not to affect the loading of materials in the yard.

[0010] Preferably, the transition conveyor unit includes a first conveyor belt and a second conveyor belt. The first conveyor belt is located beside the freight yard and parallel to the ground rail. The first conveyor belt is used to receive the material from the discharge end of the horizontal feeding mechanism. The second conveyor belt is inclined at the discharge end of the first conveyor belt and transitions the material on the first conveyor belt to the discharge conveyor belt.

[0011] The resulting technical effect is that the transition conveyor unit is used for transitional material transfer, realizing the connection between the mobile material handling machine and the discharge belt conveyor. Under normal circumstances, the second conveyor belt conveyor can tilt and transport the material to the high-level discharge belt conveyor, providing high-level loading conditions for the subsequent mobile unloading vehicle.

[0012] Preferably, the multi-joint screw conveyor unit includes at least a first screw conveyor, a second screw conveyor, and a third screw conveyor. The first screw conveyor is vertically fixed to the moving trolley, and the discharge end of the first screw conveyor is located above the horizontal feeding mechanism. The discharge flange of the second screw conveyor is connected to the inlet flange of the first screw conveyor via a toothless slewing bearing. The discharge flange of the third screw conveyor is connected to the inlet flange of the second screw conveyor via a toothed slewing bearing. A telescopic cylinder is provided between the first screw conveyor and the second screw conveyor to adjust the joint angle between the first screw conveyor and the second screw conveyor. A drive motor is provided on the second screw conveyor, and the output shaft of the drive motor is connected to the outer gear ring of the toothed slewing bearing via gear transmission to change the joint angle between the third screw conveyor and the second screw conveyor.

[0013] The resulting technical effect is that the multi-joint screw conveyor can change the material handling angle for convenient material handling, and at the same time, when not handling material, the multi-joint screw conveyor can be folded up to avoid occupying storage space in the stockyard or freight yard.

[0014] Preferably, the mobile unloading vehicle includes a vehicle body and an unloading device. The vehicle body is slidably mounted on the guide rail via rollers. The unloading device includes a three-way unloader and a telescopic belt conveyor. The three-way unloader is obliquely fixed at the top of one end of the vehicle body. The top of the three-way unloader is the inlet end and can receive the material delivered by the outlet belt conveyor. There are two sets of telescopic belt conveyors, which are respectively located at the two bottom ends of the three-way unloader. The two sets of telescopic belt conveyors are the double outlet unloading ends of the mobile unloading vehicle.

[0015] The resulting technical effect is that the vehicle body can carry the unloading device and move it. The dual unloading ends of the unloading device can connect to adjacent carriages during the loading process, without stopping the machine, enabling efficient loading and preventing material leakage.

[0016] Preferably, the three-way unloader is located beside the carriage and avoids the contact wire of the electrified railway line.

[0017] The resulting technical advantage is that the three-way unloader is located on the side of the carriage, reducing the impact of space constraints, and it will not come into contact with the electrical wiring or power grid, making it safer to use.

[0018] Preferably, the telescopic belt conveyor's mounting frame is fixedly connected to the three-way unloader, and the telescopic belt conveyor is capable of receiving and transferring materials falling from the three-way unloader.

[0019] The resulting technical effect is that the three-way unloader is arranged at an angle and has two discharge ports. Each discharge port is equipped with a telescopic belt conveyor. The telescopic belt conveyor realizes the material output and loading process. The telescopic belt conveyor can adjust the loading position, occupies a low height space, avoids contact with power grid lines, and improves the applicability of the equipment.

[0020] Preferably, a support roller is rotatably mounted on the vehicle body, the support roller being wound around the belt of the discharge conveyor and located obliquely below the redirecting roller.

[0021] The resulting technical effect is that the support roller can be coupled to the deflector roller around the belt of the discharge conveyor, and at the same time, the belt can achieve the discharge effect at the deflector roller of the unloading trolley.

[0022] Preferably, it also includes a dust suppression device, which is installed on the mobile unloading vehicle and the mobile material handling machine and is used for dust suppression during the material handling and loading process.

[0023] Preferably, the dust suppression device is a negative pressure vacuum cleaner or a spray dust suppressor.

[0024] The resulting technical effect is that the dust suppression device can suppress dust during the loading process, reducing environmental pollution during loading. Attached Figure Description

[0027] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0028] See the appendix of this invention. Figures 1 to 8 According to an embodiment of the present invention, a material handling and loading system applicable to electrified railway lines includes: Mobile material handling machine 1 is slidably mounted on the ground rails 3 on both sides of the cargo yard 2 and can pick up materials from the cargo yard. A rain shelter can be installed above the cargo yard. Transition conveyor unit 4 is located on the discharge path of the mobile reclaimer 1 and is capable of transferring and conveying materials. The discharge belt conveyor 5 is parallel to the railway track and is used to receive the material sent by the transition conveyor unit 4. The two sides of the frame of the discharge belt conveyor 5 are provided with guide rails 6 corresponding to the material conveying direction of the discharge belt conveyor 5. The mobile unloading car 7 travels on the guide rail 6 and is located on the top side of the railway track car, avoiding the contact wire 8 of the railway track and reducing space constraints. The mobile unloading car 7 is equipped with a receiving end and a double discharge end. The mobile unloading car 7 is rotatably connected to the receiving end and the redirecting roller 7011. The redirecting roller 7011 is wound around the belt of the discharge conveyor 5 and changes the direction of the belt's movement. The material of the discharge conveyor 5 enters the receiving end after passing through the redirecting roller 7011. The double discharge ends are arranged in parallel and spaced apart and can connect to adjacent cars during the loading process.

[0029] Specifically, due to the inertia of the material, the belt of the discharge conveyor rotates under the action of the redirecting roller fulcrum, and the material enters the receiving end of the mobile unloading car based on inertia; the double discharge end can connect to adjacent cars without stopping the machine and without spilling material. Specifically, at the transition between adjacent cars, the discharge end on the corresponding side can be stopped, which can be achieved by starting and stopping the telescopic belt conveyor.

[0030] In other embodiments, the mobile material handling machine 1 includes a mobile gantry frame 101, a mobile trolley 102, a multi-joint screw material handling unit 103, and a horizontal feeding mechanism 104.

The multi-joint screw material handling unit 103 is disposed on the mobile trolley 102 and picks up materials at different positions as the mobile trolley moves. The horizontal feeding mechanism 104 is an open belt conveyor, which is disposed on the top side of the mobile gantry frame 101 and can receive and transfer materials delivered by the multi-joint screw material handling unit 103 (it can receive materials along the path). The transition conveyor unit 4 is disposed on the discharge path at the discharge end of the horizontal feeding mechanism 104 and can receive and transfer materials.

[0031] In some other specific embodiments, the transition conveyor unit 4 includes a first conveyor belt 401 and a second conveyor belt 402. The first conveyor belt 401 is located beside the freight yard 2 and parallel to the ground rail. The first conveyor belt 401 is used to receive the material from the discharge end of the horizontal feeding mechanism 104. The discharge end can be connected to a drop cylinder to ensure accurate material dropping while avoiding dust. The second conveyor belt 402 is inclined at the discharge end of the first conveyor belt 401 and transitionally transfers the material on the first conveyor belt 401 to the discharge belt 5. The advantage of the inclined arrangement is that it can realize the high-level transfer of materials, which is convenient for the subsequent loading process.

[0032] In some other embodiments, the multi-joint screw conveyor unit 103 includes at least a first screw conveyor 1031, a second screw conveyor 1032, and a third screw conveyor 1033. The first screw conveyor 1031 is vertically fixed to the moving trolley 102. The discharge end of the first screw conveyor 1031 is located above the horizontal feeding mechanism 104 (belt conveyor). The discharge port flange of the second screw conveyor 1032 is connected to the feed port flange of the first screw conveyor 1031 via a toothless slewing bearing. The discharge port flange of the third screw conveyor 1033 is connected to the feed port flange of the second screw conveyor 1032 via a toothed slewing bearing. A telescopic cylinder is provided between the first screw conveyor 1031 and the second screw conveyor 1032. The telescopic cylinder adjusts the joint angle between the first screw conveyor 1031 and the second screw conveyor 1032. A drive motor is provided on the second screw conveyor 1032. The output shaft of the drive motor is connected to the outer gear ring of the toothed slewing bearing through gear transmission and changes the joint angle between the third screw conveyor 1033 and the second screw conveyor 1032. When not in use, the second and third augers can be folded at an angle to avoid affecting the stacking of materials in the yard. When in use, they can be unfolded vertically.

[0033] In some other specific embodiments, the mobile unloading vehicle 7 includes a vehicle body 701 and an unloading device 702. The vehicle body 701 is slidably mounted on the guide rail 6 via rollers. The unloading device 702 includes a three-way unloader 7021 and a telescopic belt conveyor 7022.
