Description

Technical Field

[0001] This utility model relates to the field of railway freight technology, and in particular to a single-sided cantilever movable train car leveling system. Background Technology

[0002] In recent years, with the increase in the volume of freight transported by rail, the safety of rail transport has received increasing attention. Ore transport is a crucial area of ​​rail freight, with 90% of iron ore imported to seaports needing to be transshipped inland by rail. As transport management units, railway departments require that materials be evenly distributed laterally within the carriages and that the longitudinal load difference not exceed permissible values. However, due to the bulk material's stacking characteristics, during the loading of bulk materials into train carriages using loading towers or forklifts, materials often form pointed-top piles in the middle of the carriages. Influenced by factors such as humidity, viscosity, and density, uneven material distribution and eccentric loading are common phenomena within the carriages.

[0003] The existing methods for detecting and leveling uneven loads on freight trains still rely primarily on manual labor: workers climb into the carriages as the train passes, using shovels to level the material. Each carriage takes approximately 3-10 minutes, and the entire train takes about 3-10 hours. This method is not only labor-intensive and time-consuming, but the frequent climbing, entering, and jumping of workers poses significant safety hazards. For high-density ores, which have a large bulk density, the loading height is only about half the height of the carriage, more than 1 meter below the top edge of the carriage. Ordinary loading chutes cannot reach into the carriage to level the material close to the surface. The material falls under its own weight, forming irregular, sharp-angled piles, making uneven loading particularly pronounced.

[0004] In a few areas, mechanical assistance is used, such as fixed gantry cranes and elevated cranes. These not only have the disadvantages of large land area requirements, high equipment purchase costs, and difficult operation and maintenance, but also still involve working above the carriages, posing risks such as electric shock from railway clearances and high-voltage power grids. Summary of the Invention

[0005] In view of the above-mentioned defects or deficiencies in the prior art, the present invention provides a single-sided cantilever movable train car leveling system, which occupies little space, has high safety, and greatly improves the leveling efficiency of loose materials in the train car through mechanized operation.

[0006] The purpose of this utility model is achieved as follows:

[0012] Furthermore, the leveling equipment is equipped with a driver's cab, and the operation controller is located in the driver's cab. The height of the driver's cab allows the driver to have a direct view of the leveled material inside the train track car.

[0013] Furthermore, the slewing support column is a liftable support column driven by a built-in hydraulic cylinder, the track rollers of the leveling equipment vehicle are driven by a variable frequency motor, the turntable and the spiral leveling head are driven to rotate by a hydraulic motor, the horizontal hydraulic telescopic arm and the vertical hydraulic telescopic arm are driven to extend and retract by hydraulic cylinders respectively, and a hydraulic pump station is installed on the leveling equipment vehicle.

[0014] Furthermore, the operation controller is equipped with a wireless communication device, allowing operators to remotely control the leveling operation from the ground via the wireless communication device, as well as perform automatic control through the control program.

[0015] Furthermore, a vehicle detection image recognition device is installed on one side of the train track. The vehicle detection image recognition device is wirelessly connected to the operation controller. The vehicle detection image recognition device monitors the position of the train carriage entering and exiting the steel structure support platform to assist in the leveling operation.

[0016] Furthermore, the spiral flat material head is equipped with a laser rangefinder, which detects the distance between the spiral flat material head and the front and rear of the carriage in real time to achieve safe collision prevention.

Specific implementation mode

[0026] Embodiment 1:

[0027] A single-sided cantilever type movable train carriage flat material system, as Figures 1-4 shown, includes a flat material equipment vehicle 2 located on one side of the train track 14. An arm boom mechanism 3 is provided on the flat material equipment vehicle 2. The working small arm 33 vertically arranged on the arm boom mechanism 3 is connected to the spiral flat material head 5. The flat material equipment vehicle 2 is provided with an operation controller, and the flat material equipment vehicle 2 realizes the flat material operation of the train carriage through the operation controller. The flat material equipment vehicle 2 travels on a steel structure support platform 1, and the steel structure support platform 1 is located on one side of the train track and is parallel to the train track. The steel structure support platform 1 includes a foundation support platform 11, an I-beam base rail 12 and a crane rail 6;

[0028] The I-beam base rail 12 adopts an I-shaped steel structure and is composed of an upper flange 1201, a lower flange 1202 and an intermediate vertical web 1203 connecting the two, and its shape is similar to the Chinese character "工". The I-beam base rail 12 is laid on the foundation support platform 11, and the crane rail 6 is installed on the upper surface of the upper flange 1201 of the I-beam base rail 12 using a railway rail. Both the I-beam base rail 12 and the crane rail 6 are parallel to the train track 14 for the train carriage to pass.

[0029] The leveling equipment trolley 2 rests on the traveling rail 6 via two pairs of track rollers 201 positioned at the front and rear of its lower end, and is driven to move back and forth along the traveling rail 6. Two anti-tipping limiters 7 are respectively installed on the left and right sides of the leveling equipment trolley 2, with one at the front and one at the rear, for a total of four. Each anti-tipping limiter 7 has a limiting wheel 71 at its lower end. The limiting wheel 71 is positioned between the upper and lower flanges of the I-beam base rail 12 and rolls between the upper and lower flanges as the leveling equipment trolley 2 moves, serving to withstand the lateral force when the spiral leveling head 5 levels the material. Within the channel steel formed by the upper and lower flanges, the limiting wheel 71 restricts the displacement of the leveling equipment trolley 2 in four dimensions (up, down, left, and right), effectively preventing tipping.

[0030] The boom mechanism 3 includes a slewing support column 31, a single-sided transverse cantilever 32, and a working arm 33. The single-sided transverse cantilever 32 and the working arm 33 are each equipped with a hydraulic telescopic arm. The slewing support column 31 is rotatably and vertically mounted on the leveling equipment carriage 2 via a turntable. One side of the single-sided transverse cantilever 32 is connected to the slewing support column 31, and the other side of the transverse hydraulic telescopic arm 3201 is connected and fixed to the vertically set working arm 33. The single-sided transverse cantilever 32 and the working arm 33 are each equipped with a built-in hydraulic cylinder, which is connected to the hydraulic telescopic arm. The hydraulic cylinder is equipped with a displacement sensor, which controls the extension and retraction of the hydraulic telescopic arm. The front end of the vertical hydraulic telescopic arm 3301 at the lower end of the working arm 33 is connected to the spiral leveling head 5. When the spiral leveling head 5 is retracted, it is higher than the train carriage. During operation, it can extend into the carriage to perform leveling operations and can be raised and lowered according to the height of the carriage.

[0031] The spiral leveling head 5 uses a hydraulically driven motor for bidirectional leveling, that is, in the length and width directions of the carriage. In the length direction, it relies on the moving speed of the leveling equipment carriage 2. In the width direction, the spiral leveling head 5 includes left and right spiral blades 51 that can rotate bidirectionally to distribute the material to the left and right sides of the carriage. After leveling, the material in the train carriage is evenly distributed front and back, and there is no accumulation or gaps in the material on the left and right sides.

[0032] The spiral flat feeder head 5 can be quickly disassembled and replaced by bolt fastening, and its speed can be adjusted to adapt to different materials; it is equipped with safety anti-collision mechanical limit switches in both the front and rear directions, which can send signals to the electrical control system in a timely manner to achieve safety anti-collision through the protection program.

[0033] The slewing support column 31 is a liftable support column driven by a built-in hydraulic cylinder. The track rollers 201 of the leveling equipment trolley 2 are driven by a variable frequency motor. The turntable and the spiral leveling head 5 are driven to rotate by a hydraulic motor. The horizontal hydraulic telescopic arm 3201 and the vertical hydraulic telescopic arm 3301 are driven to extend and retract by hydraulic cylinders respectively. The hydraulic system is powered by a hydraulic pump station 4, which is located on the leveling equipment trolley 2. The hydraulic pump station 4 is controlled by an operation controller to provide power hydraulics to the built-in hydraulic cylinder, hydraulic motor and hydraulic cylinder.

[0034] The steel structure support platform 1 meets the equipment's load-bearing capacity and stable operation requirements, while also meeting local climate requirements such as seismic resistance and corrosion resistance. In this embodiment, the H-beam base rail 12 is constructed from 300-type H-beams. Each H-beam is leveled and connected together. The height difference between the front and rear ends of the rail is less than 10mm, and the height difference between the two sides of the rail is less than 5mm. The trolley rail 6 uses 60mm rails, and anti-fall-off limiting devices 13 are installed at both ends of the trolley rail 6 to prevent the leveling equipment trolley 2 from going out of bounds.

[0035] The minimum clearance between the entire structure of the leveling equipment and the carriage is 760 mm, which meets the railway's clearance requirements. In this embodiment, the length of the rail 6 used to run the leveling equipment car 2 is approximately equal to the length of two train carriages.

[0036] The leveling equipment cart 2 has a drive integration box 202 at the lower center. Drive shafts 203 extend from the front and rear of the drive integration box 202, and the front and rear drive shafts 203 are respectively connected to the two pairs of track rollers set at the front and rear to form a synchronous four-wheel drive. The leveling equipment cart 2 is driven by a variable frequency motor to drive the gearbox, and drives the axle to rotate the steel wheels through two transmission shafts to achieve movement. The speed of the variable frequency motor is adjustable, and it can move forward and backward quickly in both directions. The chassis of the cart is made of high-quality carbon structural steel, and the steel grade is uniformly selected as Q355B. Buffer limit baffles are set in both the front and rear directions, and anti-falling limit devices 13 are used to prevent it from going out of bounds.

[0037] The leveling equipment trolley 2 is equipped with a driver's cab 21, and the operation controller is located inside the driver's cab 21. Preferably, the driver's cab 21 is set at a height that allows the driver to have a direct view of the leveled material inside the train track car. The driver's cab 21 is also equipped with a manual operation panel, a seat, and a heating and cooling air conditioner. The driver's cab 21 is equipped with a headlight on the roof and several cameras outside the vehicle (such as the front and rear of the driver's cab and the front and rear of the working arm) to ensure that the working conditions of the external car can be clearly seen.

[0038] The operation controller can control manual leveling operations, remote control leveling operations, and automatic control through a control program. The operation controller is equipped with wired and wireless communication devices to enable data transmission between various hardware devices and the controller. It also includes a controller (such as a PLC or industrial computer) responsible for processing sensor data and generating control commands. In this embodiment, a highly reliable and interference-resistant programmable logic controller (PLC) is selected.

[0039] The leveling system includes a vehicle detection image recognition device 8, which is installed on one side of the track along which the train carriage passes. The device is wirelessly connected to an operation controller and can monitor the position of the train carriage entering and exiting the steel structure support platform 1 in real time, feeding back the information to the intelligent control system for automatic lifting and leveling operations. The spiral leveling head 5 is equipped with a laser rangefinder, which can detect the distance to the front and rear of the carriage in real time, and a safety collision prevention system can be implemented.

[0040] For short-range communication between devices, the Modbus RTU protocol is used, which is simple, reliable, and easy to implement. For long-range communication, the MQTT protocol is used. MQTT is a lightweight message transmission protocol with low bandwidth and high reliability, which is suitable for long-range communication of IoT devices.

[0041] Example 2:

[0042] A single-sided cantilever movable train car leveling system, such as Figure 4 As shown, Embodiment 2 is an improvement upon Embodiment 1. In this embodiment, the spiral leveling head 5 includes left and right spiral blades 51 extending from the center to both sides, and arc-shaped scrapers 52 spaced apart at the rear ends of the spiral blades. The spiral blades rotate bidirectionally from the center to both sides, distributing material to the left and right sides of the carriage. The subsequent arc-shaped scrapers assist in leveling. The arc-shaped scrapers 52, positioned at the rear ends of the left and right spiral blades 51, further assist in leveling, thus achieving better leveling of the material at the front and rear of the carriage. Figure 4 In the diagram, S1 is the direction of travel of the train carriage, and S2 is the direction of travel of the flat material handling equipment car 2.

[0043] Finally, it should be noted that the above is only used to illustrate the technical solution of this utility model and not to limit it. Although this utility model has been described in detail with reference to the preferred arrangement, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model.
