Description

Technical Field

[0001] This application relates to the technical field of pantographs, and in particular to a double-aluminum-rod pantograph device for motor locomotives to prevent sparking and arcing. Background Art

[0002] With the rapid progress of modern industrial technology, motor locomotives, as efficient and reliable transportation tools, are increasingly widely used in various workplaces such as mines, factories, and ports. Deep in the mines, they undertake the transportation tasks of ores and materials, strongly supporting the production activities of the mines; inside the factories, motor locomotives shuttle between various workshops and production lines to ensure the smooth progress of the production process; at the busy ports, they are responsible for the loading, unloading, and transfer of goods, contributing to the prosperity of international trade. The wide application of motor locomotives not only improves work efficiency, reduces labor costs, but also promotes the rapid development of related industries, injecting strong impetus into the progress of modern industry.

[0003] As one of the core components of motor locomotives, the pantograph undertakes the key task of stably drawing electrical energy from the power supply line, thus providing continuous power for the motor locomotive. It is the bridge between the motor locomotive and the power supply system, ensuring the continuous and stable operation of the motor locomotive. The pantograph is finely designed and has a strong structure, capable of maintaining high efficiency in various harsh environments, providing strong guarantee for the normal operation of the motor locomotive. At the same time, the pantograph has excellent electrical conductivity and can effectively transmit electrical energy into the motor locomotive to meet its power requirements. Therefore, the pantograph plays a crucial role in the operation of the motor locomotive and is one of the key components to ensure the stable and efficient operation of the motor locomotive.

[0004] Currently, during the operation of the motor locomotive pantograph device, due to various natural factors such as wind force, temperature change, humidity change, etc., the contact state between the pantograph and the contact wire changes. This change may cause the movement of the pantograph, which further leads to the generation of sparking and arcing phenomena, reducing the safety of the device. Utility Model Content

[0005] The purpose of this application is to solve the problem that the movement of the pantograph causes the change of the contact state with the contact wire, resulting in the generation of sparking and arcing phenomena and reducing the safety of the device. This application provides a double-aluminum-rod pantograph device for motor locomotives to prevent sparking and arcing.

[0006] This application specifically adopts the following technical solutions to achieve the above purpose:

[0007] A double-aluminum-rod pantograph device for preventing electric locomotive from sparking and arcing, including a pantograph base. An adjustment chute is provided at the top of the pantograph base. An adjustment slider is slidably connected inside the adjustment chute. The top of the adjustment slider is fixedly connected with a pantograph frame. Aluminum rod bodies are symmetrically installed at the top of the pantograph frame. One end of the adjustment chute is symmetrically provided with airtight chutes. A T-shaped adjustment rod is slidably connected inside the airtight chutes. One end of the T-shaped adjustment rod extends into the adjustment chute and abuts against the adjustment slider. One end of the airtight chute is fixedly connected with an air duct. One end of the air duct is fixedly connected with a regulating valve. The input ends of the two regulating valves are fixedly connected with air supply hoses. One end of the airtight chute is fixedly connected with an exhaust pipe. One end of the exhaust pipe passes through the pantograph base and is fixedly connected with an exhaust valve. A monitoring component is installed at one end of the pantograph base.

[0008] By adopting the above technical solution, through the coordinated use of the monitoring component with the regulating valve, the exhaust valve, and the T-shaped adjustment rod, it is convenient to externally connect an air pump through the air supply hose, and then control the opening and closing of the regulating valve and the exhaust pipe according to the detection data of the monitoring component, so as to adjust the air pressure inside the airtight chute to change, and push the T-shaped adjustment rod to drive the adjustment slider to drive the aluminum rod body to move along the length direction of the adjustment chute. At the same time, the middle section of the contact wire and the aluminum rod body are adjusted to contact, so as to facilitate the real-time adjustment of the contact state between the pantograph and the contact wire, reduce the sparking and arcing phenomena caused by the movement of the pantograph, and improve the safety of the device.

[0009] Further, the monitoring component includes a mounting seat installed on one side of the pantograph base.

[0013] Further, a rubber sealing sleeve is fixedly connected to one end of the T-shaped adjustment rod. The rubber sealing sleeve abuts against the inner wall of the airtight chute.

[0014] By adopting the above technical solution, through the combined use of the rubber seal sleeve and the T-shaped adjusting rod, it is convenient to utilize the elastic deformation characteristic of the rubber seal sleeve, so that the T-shaped adjusting rod cooperates with the airtight chute to extrude the rubber seal sleeve to generate deformation and fill between the T-shaped adjusting rod and the airtight chute, thereby effectively improving the sealing performance between the T-shaped adjusting rod and the airtight chute.

[0015] Furthermore, a plurality of support rollers are symmetrically and rotatably connected to the top of the bow seat, and the bow frame is in rolling contact with the support rollers.

[0017] Furthermore, a wear-resistant rubber sleeve is fixedly sleeved on one end of the support roller.

[0018] By adopting the above technical solution, by setting the wear-resistant rubber sleeve, a flexible contact is formed between the support roller and the bow frame, further reducing the wear between the bow frame and the support roller.

[0019] Furthermore, a glass fiber insulating board is fixedly connected to one side of the bow seat, and the mounting seat is fixedly connected to the glass fiber insulating board.

[0023] In summary, the present application includes at least one of the following beneficial effects:

[0024] 1. By adopting the combined use of the monitoring component, the regulating valve, the exhaust valve, and the T-shaped adjusting rod, it is convenient to externally connect an air pump through an air delivery hose, and then control the opening and closing of the regulating valve and the exhaust pipe according to the detection data of the monitoring component, so as to adjust the change of the air pressure inside the airtight chute and push the T-shaped adjusting rod to drive the adjusting slider to drive the aluminum rod body to move along the length direction of the adjusting chute, and at the same time adjust the middle section contact between the contact wire and the aluminum rod body, thereby facilitating the real-time adjustment of the contact state between the pantograph and the contact wire, reducing the arcing and sparking phenomena caused by the movement of the pantograph, and improving the safety of the device.

[0031] The following will Figures 1 - 3 further describe this application in detail.

[0032] The embodiment of this application discloses a double-aluminum-rod pantograph device for preventing sparking and arcing of an electric locomotive.

[0033] Referring to Figures 1 - 3 , a double-aluminum-rod pantograph device for preventing sparking and arcing of an electric locomotive includes a bow seat 1. An adjusting sliding groove 2 is opened at the top of the bow seat 1. An adjusting slider 3 is slidably connected inside the adjusting sliding groove 2. The top of the adjusting slider 3 is fixedly connected with a bow frame 4. Aluminum rod bodies 5 are symmetrically installed at the top of the bow frame 4. Airtight sliding grooves 21 are symmetrically opened at one end of the adjusting sliding groove 2. A T-shaped adjusting rod 6 is slidably connected inside the airtight sliding groove 21. One end of the T-shaped adjusting rod 6 extends into the adjusting sliding groove 2 and abuts against the adjusting slider 3. An air duct 7 is fixedly connected to one end of the airtight sliding groove 21. A regulating valve 8 is fixedly connected to one end of the air duct 7. The input ends of two regulating valves 8 are fixedly connected with an air conveying hose 9. An exhaust pipe 10 is fixedly connected to one end of the airtight sliding groove 21. One end of the exhaust pipe 10 passes through the bow seat 1 and is fixedly connected with an exhaust valve 11. A monitoring component is installed at one end of the bow seat 1;

[0034] Among them, the monitoring component includes a mounting seat 12 installed on one side of the bow seat 1. One end of the mounting seat 12 is fixedly connected to a camera 13, and one end of the mounting seat 12 is fixedly connected to a controller 14. The controller 14 is electrically connected to the camera 13, the regulating valve 8, and the exhaust valve 11;

[0035] Moreover, one end of the aluminum rod body 5 is symmetrically and fixedly connected to a ball bearing 15, and the ball bearing 15 is fixedly connected to the bow frame 4;

[0036] Moreover, one end of the T-shaped adjusting rod 6 is fixedly connected to a rubber sealing sleeve 16, and the rubber sealing sleeve 16 abuts against the inner wall of the airtight chute 21.

[0037] During use, first, an air pump is externally connected through the air delivery hose 9. Then, the camera 13 is set to collect the contact image between the aluminum rod body 5 and the contact wire. When the contact point between the contact wire and the aluminum rod body 5 is offset, the monitoring image signal is transmitted to the controller 14 through the camera 13, and the controller 14 sends opening and closing signals to the regulating valve 8 and the exhaust pipe 10 respectively, so that the two regulating valves 8 operate in a way that one is closed and the other is opened. At the same time, the exhaust valve 11 in the same direction as the opened regulating valve 8 closes the inside of the exhaust pipe 10, and the opposite exhaust valve 11 opens the inside of the exhaust pipe 10. Then, the air delivery hose 9 guides the gas output by the air pump into the airtight chute 21 on the side where the exhaust valve 11 is closed through the air guide pipe 7, so that the air pressure inside the airtight chute 21 increases, and the T-shaped adjusting rod 6 is pushed to drive the rubber sealing sleeve 16 to push the adjusting slider 3 along the length direction of the airtight chute 21 to drive the bow frame 4 to move. The gas inside the airtight chute 21 on the opposite side is discharged through the exhaust pipe 10 under the push of the T-shaped adjusting rod 6. Furthermore, the bow frame 4 drives the aluminum rod body 5 to move along the length direction of the adjusting chute 2, and adjusts the middle section contact between the contact wire and the aluminum rod body 5, so as to drive the aluminum rod body 5 to form a rolling contact with the contact wire in cooperation with the ball bearing 15, effectively reducing the wear between the aluminum rod body 5 and the contact wire, extending the service life of the device, thus facilitating the real-time adjustment of the contact state between the pantograph and the contact wire, reducing the arcing and sparking phenomena caused by the movement of the pantograph, and improving the safety of the device.

[0038] Refer to Figure 1 and Figure 2 On the top of the bow seat 1, a plurality of support rollers 17 are symmetrically and rotatably connected, and the bow frame 4 is in rolling contact with the support rollers 17;

[0039] Among them, one end of the support roller 17 is fixedly sleeved with a wear-resistant rubber sleeve 18.

[0040] During use, first, the supporting roller 17 is set to push the wear-resistant rubber sleeve 18 to form a flexible contact with the bow frame 4. At the same time, when driving the bow frame 4 to move along the length direction of the adjustment chute 2, the supporting roller 17 drives the wear-resistant rubber sleeve 18 to form a rolling contact with the bow frame 4, thereby effectively reducing the wear between the bow frame 4 and the bow seat 1 and extending the service life of the device.

[0041] Referring to Figure 1 and Figure 2 , a glass fiber insulating board 19 is fixedly connected to one side of the bow seat 1, and the mounting seat 12 is fixedly connected to the glass fiber insulating board 19.

[0042] During use, by using the glass fiber insulating board 19 to form an insulating partition between the mounting seat 12 and the bow seat 1, the influence of the surface current of the bow seat 1 on the camera 13 is effectively reduced, and the safety of the device is improved.

[0043] Referring to Figure 1 and Figure 2 , a night vision lamp 20 is symmetrically and fixedly connected to one end of the mounting seat 12.

[0044] During use, when insufficient light affects the clarity of the image acquisition of the aluminum rod body 5 and the contact wire by the camera 13, the night vision lamp 20 is turned on to illuminate the contact end of the aluminum rod body 5 and the contact wire, thereby improving the image acquisition effect of the camera 13.

[0045] The implementation principle of the double-aluminum-rod current collector bow device for motor vehicles to prevent sparking and arcing in this embodiment is as follows: First, an air pump is externally connected through the air delivery hose 9, and then the camera 13 is set to collect the contact image of the aluminum rod body 5 and the contact wire. When the contact point between the contact wire and the aluminum rod body 5 is offset, the monitoring image signal is transmitted to the controller 14 through the camera 13, and the controller 14 sends opening and closing signals to the regulating valve 8 and the exhaust pipe 10 respectively, so that the two regulating valves 8 operate in a way that one is closed and the other is opened. At the same time, the exhaust valve 11 in the same direction as the opened regulating valve 8 closes the inside of the exhaust pipe 10, while the opposing exhaust valve 11 opens the inside of the exhaust pipe 10. Then, the air delivery hose 9 introduces the gas output by the air pump into the airtight chute 21 on the side where the exhaust valve 11 is closed through the air guide pipe 7, so that the air pressure inside the airtight chute 21 increases, and the T-shaped adjusting rod 6 is pushed to drive the rubber sealing sleeve 16 to push the adjusting slider 3 along the length direction of the airtight chute 21 to drive the bow frame 4 to move. The gas inside the opposing airtight chute 21 is pushed by the T-shaped adjusting rod 6 and discharged through the exhaust pipe 10. Furthermore, the bow frame 4 drives the aluminum rod body 5 to move along the length direction of the adjustment chute 2 and adjusts the middle section contact between the contact wire and the aluminum rod body 5.

[0046] Meanwhile, when driving the driving bow frame 4 to move along the length direction of the adjustment chute 2, the support roller 17 drives the wear-resistant rubber sleeve 18 to form a rolling contact with the bow frame 4. When driving the aluminum rod body 5 to contact the contact wire, by arranging the aluminum rod body 5 to cooperate with the ball bearing 15 to form a rolling contact with the contact wire, the wear between the aluminum rod body 5 and the contact wire is effectively reduced.
