Description

Technical Field

[0001] This invention relates to the field of vehicle-mounted power boom application technology, specifically to a combined power boom vehicle device for disassembling and assembling the lower side door panel of an open wagon in a train freight car. Background Technology

[0002] Railways are a vital component of modern transportation, and the maintenance and upkeep of railway equipment and facilities are equally crucial. Regular inspections are necessary to ensure the safety, stability, and reliability of railway operations. Maintenance work requires a comprehensive inspection of railway equipment and facilities, including tracks, switches, and signaling equipment. If any problems are found, timely repairs and maintenance are essential. The disassembly and assembly of the underside doors of open wagons is also a significant part of the vehicle maintenance process.

[0003] Currently, disassembling the lower side doors of open freight cars requires two people and one vehicle: two workers and one forklift. One worker must be a special equipment operator with a valid special operation certificate, and the forklift, being special equipment, also requires a valid annual inspection. The forklift is used for disassembling and assembling the doors. The workers are responsible for lifting the doors and loading / unloading the door pins, while the forklift driver operates the forklift to disassemble and assemble the doors. Having two people simultaneously disassembling and assembling doors is time-consuming, labor-intensive, and cannot be done concurrently. This not only wastes a significant amount of manpower but also poses a risk of doors falling and injuring workers, making it inherently dangerous.

[0004] To address the aforementioned problems, this invention provides a combined power boom vehicle device for disassembling and assembling the lower side door panels of open wagons in train freight cars, which requires only one person and one vehicle (the person is an ordinary worker and the vehicle is an ordinary vehicle) to complete the entire task. Summary of the Invention

[0005] To address the shortcomings of existing technologies, the current method of dismantling the lower side doors of open freight cars requires two people per vehicle, which not only wastes a significant amount of manpower but also poses a risk of doors falling and injuring workers. This application provides a combined power boom vehicle device for dismantling and assembling the lower side doors of open freight cars. Different controllers issue commands to control different devices to work in coordination. First, the door to be dismantled is connected to the combined power boom, which consists of a lifting device, a tilting device, a connecting plate, and a rotating device. Then, the controller controls the combined power boom to remove the door from the train car and place it onto the combined power boom vehicle device. This process can be repeated to install a new door, thus saving manpower and resources, enabling simultaneous and efficient dismantling and assembly operations, reducing overall operation time, improving overall work efficiency, preventing door falls from injuring workers, and enhancing overall operational safety.

[0006] To achieve the above objectives, the technical solution adopted in this application is as follows:

[0007] A combined power boom vehicle device for disassembling and assembling the lower side door panel of a train freight car includes a disassembly and assembly vehicle and a support plate installed on the upper end of the disassembly and assembly vehicle. The top surface of the support plate is provided with a combined power boom composed of a lifting device, a tilting device, a connecting plate and a rotating device connected to each other.

[0008] The mounting frame is also provided on the bottom surface of the support plate. The mounting frame is equipped with a hydraulic station for controlling the displacement of the disassembly and assembly vehicle and an electrical control box. The electrical control box is connected to a second controller for remote signal control of the combined power arm operation.

[0009] To ensure work safety, as a further improvement of the present invention, the connecting plate and the lifting device are welded together, and the connecting plate is horizontally welded to the top surface of the lifting device. Since the lower door panel is heavier, welding is used to increase the connection strength and prevent the connecting plate or lifting device from being unable to bear the weight of the lower door panel, thus preventing breakage and the door panel from falling and injuring workers.

[0010] To facilitate the disassembly and assembly of the door panel to be replaced, as a further improvement of the present invention, the rotating device includes a reducer mounted on the connecting plate. A rotating arm is mounted on the output shaft of the reducer. Steel wire rope suspension shafts are provided at both ends of the side of the rotating arm, and these steel wire rope suspension shafts are cylindrical and welded to both ends of the top surface of the rotating arm. A second drive motor for providing power is also mounted on the top surface of the reducer. The second drive motor is electrically connected to the electrical control box via a wiring harness. Using a first controller, the steel wire rope suspension shafts at both ends of the top surface of the rotating arm can be hoisted together with the door panel to be disassembled. Then, by continuing to operate the first and second controllers, the disassembly and assembly of the door panel can be achieved.

[0011] To enable the disassembly and assembly of lower door panels at different heights, as a further improvement of the present invention, the lifting device includes a telescopic arm outer sleeve, a telescopic arm inner sleeve, and a second hydraulic cylinder for lifting. The telescopic arm outer sleeve is mounted on two bearing seats via a mounting shaft welded to the bottom. The bearing seats are mounted on the top surface of the support plate. The telescopic arm inner sleeve is nested inside the telescopic arm outer sleeve. Hydraulic cylinder mounting seats are welded to the same end faces of the telescopic arm outer sleeve and the telescopic arm inner sleeve, respectively. The second hydraulic cylinder is installed between the two hydraulic cylinder mounting seats. The overall height of the lifting device is then adjusted using the second hydraulic cylinder, thereby enabling the disassembly and assembly of door panels at different heights.

[0012] As a further improvement of the present invention, the tilting device is disposed on either side of the lifting device, the tilting device is a first hydraulic cylinder, a hydraulic cylinder mounting seat is disposed on one side of the lifting device, and a hydraulic cylinder mounting seat is also disposed on the top surface of the bearing plate in the corresponding direction, and the first hydraulic cylinder is mounted on the two hydraulic cylinder mounting seats, and the first hydraulic cylinder is connected to the hydraulic pipeline of the hydraulic station.

[0013] To adapt to different road conditions or terrains, as a further improvement of the present invention, the disassembly and assembly vehicle includes two identical drive assemblies and two tracks. The drive assemblies are welded together by two connecting beams, and the tracks are mounted on the drive assemblies. Each connecting beam is equipped with a first drive motor for providing power. Due to the complexity of the road conditions at the work site, a track-driven method is adopted. Tracks not only have the advantages of large force-bearing area, good grip, and low pressure on the ground, but also prevent the vehicle body from sinking. The structure is simple, sturdy, and durable.

[0014] To further improve the smoothness of the vehicle's operation, the drive assembly includes a drive beam welded to the connecting crossbeam. Main road wheels are mounted on both sides of the drive beam, and floating supports are mounted on the drive beam. Two floating wheels are mounted on the floating supports, and two floating supports are mounted on the drive beam. A tension wheel is mounted at one end of the upper side of the drive beam, a drive wheel at the other end, and a trailing wheel is mounted in the middle. The drive wheel is mounted on the drive shaft of the first drive motor. In summary, the vehicle body is equipped with road wheels and floating road wheels, allowing the vehicle to sway freely according to the unevenness of the ground to cope with various complex road surfaces, resulting in smoother vehicle operation. The tension wheel mounted on the drive beam is used to adjust the track tension. The trailing wheel mounted on the drive beam in the middle of the track supports the track, preventing excessive swaying or sagging, and ensuring smooth operation of the vehicle.

[0015] To prevent the combined power boom from tipping over and falling due to gravity during operation, as a further improvement of the present invention, a protective cover is also provided on the top surface of the bearing plate to protect the combined power boom. The top surface of the protective cover is an open design. By providing a protective cover outside the lifting device included in the combined power boom, the combined power boom is prevented from tipping over and falling due to gravity during operation. Even if it does tip over and fall, it can be supported by the protective cover to ensure the overall safety during operation.

[0016] In summary, compared with the prior art, this application includes at least one of the following beneficial technical effects:

[0017] 1. In this application, the combined power arm is composed of a lifting device, a connecting plate, and a rotating device connected to each other. The lifting device and tilting device in the combined power arm are controlled by a first controller, which then receives the command and controls it via an electrical control box, and finally the hydraulic station provides power. Similarly, the rotating device in the combined power arm is controlled by a first controller which sends a command to the electrical control box, which then drives a second drive motor to rotate. When performing door panel disassembly and assembly operations, the door panel to be disassembled and assembled is hoisted onto the rotating device, and then the controller is manually operated to perform the disassembly and assembly operations. Through the above work steps, not only can manpower and material resources be saved, and the disassembly and assembly operations be carried out simultaneously and efficiently, reducing the overall operation time and improving the overall work efficiency, but also the situation of door panels falling and injuring workers can be avoided, thus improving the overall safety of the operation.

[0018] 2. In this application, due to the complexity of the road conditions at the work site, a tracked drive system is adopted. Tracks not only have the advantages of a large force-bearing area, good grip, and low pressure on the ground, making it less likely for the vehicle to sink, but also have a simple, sturdy, and durable structure. The vehicle is equipped with road wheels and floating wheels, allowing the disassembly / assembly vehicle to swing freely according to the unevenness of the ground to cope with various complex road surfaces, making the vehicle run more smoothly. Tensioning wheels mounted on the drive beam are used to adjust the track tension. A trailing wheel is mounted on the drive beam in the middle of the track to support the track above, preventing excessive swaying or sagging, and ensuring the smooth operation of the disassembly / assembly vehicle.

[0033] Example 1:

[0034] Refer to the instruction manual. Figures 1-6 The present invention relates to a combined power boom vehicle device for disassembling and assembling the lower side door panel of a train freight car, comprising a disassembly and assembly vehicle 3 and a support plate 6 provided on the upper end of the disassembly and assembly vehicle 3. The top surface of the support plate 6 is provided with a combined power boom composed of a lifting device 4, an tilting device, a connecting plate 7 and a rotating device 5 connected to each other.

[0035] The bottom surface of the support plate 6 is also provided with the mounting frame 9. The mounting frame 9 is equipped with a hydraulic station 8 for controlling the displacement of the disassembly and assembly vehicle 3 and an electrical control box 12. The electrical control box 12 is connected to a second controller 11 for remote signal control of the combined power arm operation.

[0036] according to Figure 1 and Figure 2 As shown, in order to ensure the safety of the equipment, the connecting plate 7 and the lifting device 4 are welded together, and the connecting plate 7 is horizontally welded to the top surface of the lifting device 4. The connection strength is increased by welding, making the connection between the connecting plate 7 and the lifting device 4 more secure, and avoiding breakage and the situation where the door panel falls and injures the worker.

[0037] In this device, the support plate 6 is installed on the upper part of the vehicle. The combined boom power arm is mounted on the upper part of the support plate 6, and there is also an area for placing the lower side door panel. The mounting bracket 9 is installed at one end of the vehicle below the support plate 6, and is used to install the hydraulic station 8 and the electrical control box 12. The hydraulic station 8 provides power to the combined boom power arm lifting device 4 and tilting device. The rotating device 5 of the combined boom is driven by a motor, with the drive power provided by the electrical components inside the electrical control box 12. Sheet metal parts are also installed on the upper part of the support plate 6 to protect the combined boom. Sheet metal parts are also installed on the side door to enhance the appearance and protect the vehicle.

[0038] according to Figure 1 Figure 6 As shown, the first hydraulic cylinder 2, located on one side of the lifting device 4, enables the combined power arm, which is composed of the lifting device 4, the tilting device, the connecting plate 7, and the rotating device 5, to tilt. In the tilting direction, the height of the lifting device 4 is controlled. The combined power arm adopts a boom-in-boom structure with a vertical extension length of 1000mm, a horizontal tilt of ±45°, and a horizontal rotation of 360°. The main arm adopts an L-shaped design, which is composed of the lifting device 4 and the connecting plate 7. It can complete the vertical extension and horizontal tilting of the door panel. The lifting and tilting actions are hydraulically driven, and the rotating device 5 is driven by different drive motors powered by the power supply.

[0039] It is worth noting that the hydraulic station 8 uses a 48V brushless motor, and the second controller 11 is a wireless remote control for controlling the vehicle. The remote control has two joysticks; operating the joysticks allows the vehicle to move forward, backward, turn left, turn right, and rotate in place. In this device, the motor and controller are integrated, equipped with two-way bidirectional throttle valves and solenoid valves, responsible for the power output of different cylinders in the combined power arm. Under the control of the control system, hydraulic oil is delivered to the hydraulic cylinders at a set pressure and flow rate, causing the combined power arm to move at the corresponding speed. The control system is the control center of this equipment, equipped with a vehicle power battery charging system, a 48V-24V power conversion system, a rotary motor speed control system and a hydraulic station 8 speed control system, a main controller for vehicle movement, and two brushless motor controllers. These systems work together to control the combined power arm and the disassembly / assembly vehicle 3 for the disassembly and assembly of the lower side doors of the open wagons of the train freight cars.

[0040] It is worth noting that the core of the lower door panel disassembly and assembly operation is a combined power arm, responsible for the positional transfer of the door panel between the train car and the combined power arm vehicle device. The combined power arm can perform horizontal, vertical, and 360-degree rotation movements of the door panel, completing the disassembly and assembly of the train door panel through a combination of movements. The battery pack, located inside the vehicle, is the power source for the entire device. It uses a 48V 107AH road vehicle-specific lead-acid battery pack, consisting of four 12V batteries connected in series. It provides DC power to the vehicle and the hydraulic station 8. The electrical control box 12 contains a charging system responsible for charging the batteries, and the vehicle body is equipped with an external 220V aviation power socket.

[0041] The aforementioned combined power boom, through the cooperation of the lifting device 4, tilting device, and rotating device 5, can move a door panel vertically installed at the lower side door position of the train car to this device for horizontal placement in the door panel placement area; this action is the door panel disassembly operation. Alternatively, a door panel placed horizontally on this device can be vertically installed onto the train car; this process is the door panel installation operation. All of the above operations are performed by the operator through the first controller 54, which is mounted on the connecting plate 7 of the combined power boom.

[0042] Example 2:

[0043] This embodiment is a further optimization of the structure and principle of embodiment 1. To facilitate the disassembly and assembly of the door panel, the rotating device 5 includes a reducer 52 mounted on the connecting plate 7. A rotating arm 51 is welded to the output shaft of the reducer 52. Wire rope suspension shafts 56 are provided at both ends of the top surface of the rotating arm 51. The wire rope suspension shafts 56 are cylindrical and welded to both ends of the top surface of the rotating arm 51. The top surface of the reducer 52 is also driven by a second drive motor 55 for providing power. The second drive motor 55 is electrically connected to the electrical control box 12 via a wiring harness 53. The electrical control box 12 is also connected to a first controller 54 via wires. By operating the forward and reverse buttons on the first controller 54, the operator can control the internal speed controller after the electrical control box 12 recognizes the command and outputs drive power to the second drive motor 55. The door panel suspended on the rotating device 5 rotates, causing the door panel mounted vertically on the train carriage to be converted to a horizontal position. The operator operates the forward and reverse buttons on the first controller 54. After the electrical control box 12 recognizes the command, it controls the internal speed controller and outputs drive power to the second drive motor 55. The door panel, which is suspended on the rotating device 5, rotates, so that the door panel installed vertically on the train car is converted to the horizontal position.

[0044] according to Figure 1 and Figure 2As shown, a rotating arm 51 is installed on the rotating device 5 at the end of the L-shaped arm. The length of the rotating arm 51 is 1000mm. Driven by the second drive motor 55 and the reducer 52, the rotating arm 51 can rotate 360°. The voltage of the second drive motor 55 is 24V. A 48V-24V, 50A voltage converter is used to complete the voltage conversion. The speed is controlled by the brushed motor controller. The combined power arm, through the cooperation of the lifting device 4, the tilting device and the rotating device 5, can make the lower door panel perform horizontal, vertical, tilting and rotating movements, thereby making the door panel easy and quick to disassemble and assemble.

[0045] It is worth noting that, in order to enable the rotating arm 51 connected to the reducer 52 to bear the weight of the door panel, the reducer 52 in the rotating device 5 is welded to the end face of the connecting plate 7, and the reducer 52 is driven by the second drive motor 55. Welding the reducer 52 to the end face of the connecting plate 7 can maximize the connection strength between the connecting plate 7 and the rotating device 5, and prevent the connecting plate 7 or the lifting device 4 from being unable to bear the weight of the lower door panel, thus preventing breakage and the door panel from falling and injuring workers.

[0046] It is further worth noting that the first controller 54 is suspended on the connecting plate 7 of the combined power arm and is responsible for the motion control of the combined power arm. It is electrically connected to the electrical control box 12. The first controller 54 is equipped with up, down, left, right, forward, and reverse command buttons. The up and down buttons are used to control the lifting device 4 of the combined power arm to perform lifting actions. The left and right buttons are used to control the tilting action of the combined power arm to complete the horizontal movement of the door panel. The forward and reverse buttons are used to control the rotation action of the rotating arm 51 on the rotating device 5 of the combined power arm to complete the conversion between the horizontal and vertical states of the door panel during operation.

[0047] Example 3:

[0048] This embodiment is a further optimization of the structure and principle of embodiment 1. In order to enable the disassembly and assembly of the lower door panels at different heights, the lifting device 4 is responsible for the vertical lifting action during the door panel position change. It includes a telescopic arm outer sleeve 43, a telescopic arm inner sleeve 41, and a second hydraulic cylinder 42 that performs the lifting action. The telescopic arm outer sleeve 43 is mounted on the bearing seat 10 through a mounting shaft welded to the bottom. The bearing seat 10 is mounted on the top surface of the bearing plate 6. The telescopic arm inner sleeve 41 is nested inside the telescopic arm outer sleeve 43. Fixed seats are welded to the same side end faces of the telescopic arm outer sleeve 43 and the telescopic arm inner sleeve 41, and the second hydraulic cylinder 42 is installed between the two mounting seats. The second hydraulic cylinder 42 is fixed between the two mounting seats by the mounting seats installed on the telescopic arm outer sleeve 43 and the telescopic arm inner sleeve 41. The second hydraulic cylinder 42 is connected to the hydraulic pipeline of the hydraulic station 8; the operation of the lifting device 4 is initiated by the operator through the operation of the first controller 54. The electrical control box 12 recognizes the lifting or lowering command and controls the hydraulic station 8 to drive the second hydraulic cylinder 42, so that the lifting device 4 completes the lifting action.

[0049] It is worth noting that the tilting device is installed on one side of the lifting device 4. The tilting device is responsible for the horizontal movement of the door panel during position changes. The tilting device includes one first hydraulic cylinder 2 and two hydraulic cylinder mounting seats. A hydraulic cylinder mounting seat is provided on one side of the lifting device 4, and another hydraulic cylinder mounting seat is provided on the top surface of the support plate 6 on the same side of the lifting device 4. The first hydraulic cylinder 2 is mounted on both hydraulic cylinder mounting seats and is connected to the hydraulic station 8 via hydraulic lines. The operator issues a left or right tilt command through the first controller 54. The electrical control box 12 recognizes the left or right tilt command and controls the hydraulic station 8 to drive the first hydraulic cylinder 2, causing the tilting device to complete the tilting action and move the door panel horizontally.

[0050] Example 4:

[0051] This embodiment is a further optimization of the structure and principle of embodiment 1. In order to adapt to different road conditions or terrains, the disassembly and assembly vehicle 3 includes two identical drive assemblies 31 and two tracks 33. The drive assemblies 31 are welded together by two connecting beams 34. The tracks 33 are mounted on the drive assemblies 31. Each drive assembly 31 is also connected to a first drive motor 32 for providing power. Due to the complexity of the road conditions at the work site, the track 33 drive method is adopted. The tracks 33 not only have the advantages of large force-bearing area, good grip, and low pressure on the ground, but also do not easily cause the vehicle body to sink. The structure is simple, sturdy and durable.

[0052] It is worth noting that the disassembly and assembly vehicle 3 carries the combined power boom and the door panels to be disassembled and assembled. The maximum loading capacity of the door panels is 12, and the maximum designed weight is 1.5 tons. It is equipped with two DC brushless motors and two tracks 33 with a width of 230mm.

[0053] In this device, the three directions of vehicle assembly and disassembly are determined as follows: the combined power arm is located on one side of the long side of the vehicle, which is the forward direction, and the opposite direction is the backward direction. When the operator stands on one side of the combined power arm, the left hand is the left and the right hand is the right. The rotating arm 51 rotates clockwise for forward rotation and counterclockwise for reverse rotation.

[0054] according to Figures 1-6 As shown, in order to make the disassembly and assembly vehicle 3 run more smoothly, the drive assembly 31 also includes a drive beam 317. The drive beam 317 is welded to the connecting crossbeam 34. Both sides of the drive beam 317 are connected to main road wheels 311 that are engaged with the track 33. A floating bracket 312 is bolted to the side of the drive beam 317. The floating bracket 312 has four load-bearing floating wheels 313 in the middle. The load-bearing floating wheels 313 are installed in pairs on the drive beam 317. A pair of tension wheels 315, a trailing wheel 314, and a drive wheel 316 that are engaged with the track 33 are also installed on the drive beam 317 from left to right via mounting seats. The pair of drive wheels 316 are rotatably connected to the drive shaft of the first drive motor 32. In summary, the vehicle body is equipped with load-bearing wheels 311 and load-bearing floating wheels 313, which allows the disassembly and assembly vehicle 3 to swing freely with the unevenness of the ground to cope with various complex road surfaces and make the vehicle body run more smoothly. The tensioning wheel 315 installed on the drive beam 317 is used to adjust the tension of the track 33. A trailing wheel 314 is installed on the drive beam 317 in the middle of the track 33. Its function is to support the track 33 above it, prevent it from shaking too much or sagging, and ensure the smooth operation of the disassembled vehicle 3.

[0055] It is worth noting that, in order to prevent the combined power arm from tipping over and falling due to gravity during operation, the top surface of the bearing plate 6 is also provided with a protective cover 1 to prevent the combined power arm from tipping over. The top surface of the protective cover 1 is open. By setting the protective cover 1 outside the lifting device 4 included in the combined power arm, the combined power arm can be prevented from tipping over and falling due to gravity during operation. Even if it does tip over and fall, it can be supported by the protective cover 1 to ensure the safety of the whole operation.

[0056] Working principle description:

[0057] The working principle of installing door panels:

[0058] When the equipment is parked: the lifting device 4 is in the lowest extension position, the tilting device must ensure that the power combination arm is in a vertical state, and the rotating arm 51 in the rotating device 5 must be in a horizontal state.

[0059] Preparations before the first operation: Install the two special lifting tools with wire ropes onto the two lifting shafts of the rotating arm 51 respectively.

[0060] Door panel installation process:

[0061] First, control the disassembly and assembly vehicle 3 to move to the designated position in the carriage. Then, use a forklift to place the stacked door panels horizontally onto the designated position on the support plate 6 on top of the disassembly and assembly vehicle 3. Next, place the two special lifting tools at the lower end of the lifting rope into the lifting positions on both sides of the door panel. Press the down command button on the second controller 11 to lift the door panel to the appropriate height. Then, press the forward rotation command button on the first controller 54 to change the door panel from a horizontal to a vertical position, aligning the position and direction of the mounting holes. Next, press the left tilt command button on the second controller 11 to tilt the door panel towards the train carriage, moving it to the vicinity of the carriage. By coordinating the use of various command buttons on the second controller 11, align the two hinge holes of the door panel with the mounting holes of the mounting seats on the carriage. Then, install the pin on the hinge seat, continue operating the down command button on the second controller 11 to loosen the lifting wire rope and remove the lifting tools. Then, press the various command buttons on the second controller 11 to convert the combined power arm to a vertical position, repeating the above steps to continue installing the second door panel.

[0062] The working principle and procedure for disassembling the door panel:

[0063] Press the command button on the second controller 11 to control the disassembly and assembly vehicle 3 to move towards the designated position in the direction of the cargo compartment. Press the command button on the first controller 54 to move the lifting tools to the lower position of the door panel lifting position, and install the two lifting tools into the lifting holes of the door panel.
