Description

Technical Field

[0001] The utility model belongs to the technical field of railway catenary insulator cleaning, and particularly relates to an integrated intelligent water flushing vehicle for catenary insulators. Background Technique

[0002] Catenary insulators play a role in support and insulation, which is crucial for railway operation safety. If the surface of the insulator is contaminated by attachments such as dust and dirt, its insulation performance will be reduced, increasing the risk of discharge. Therefore, regular cleaning can effectively remove these attachments and ensure the good insulation performance of the insulator.

[0003] The current cleaning methods mainly include manual cleaning, aerosol cleaning agent cleaning, and live water flushing. Manual cleaning has strong pertinence and can take into account the cleaning of some special positions, such as vertical line segments, railway bridges, turnouts and other areas that are difficult to reach by mechanical cleaning, and only manual cleaning can be adopted. However, manual cleaning has low efficiency, high labor intensity, and great potential safety hazards. Using aerosol cleaning agent cleaning can achieve good cleaning effect and good safety, but its operation difficulty is large, cleaning cost is high, cleaning efficiency is low, and there is a risk of environmental pollution. Live water flushing does not require power supply interruption during the cleaning process, ensuring the normal operation of the train, reducing the economic losses and social impacts caused by power outages; using the powerful water flow generated by a high-pressure water gun to flush the insulator, its large pressure and range can quickly and effectively remove the stains and impurities on the surface of the insulator and restore its insulation performance, with good flushing effect; during the flushing process, the water flushing operation vehicle can run uniformly on the railway track at a working speed of 5-10 km / h, realizing the cleaning operation without stopping, with high cleaning efficiency and simple and convenient operation. Due to the advantages of high cleaning efficiency, simple operation, and low cleaning cost of the live water flushing operation method, it has gradually replaced other cleaning methods such as manual cleaning and is widely used in the maintenance of railway catenaries.

[0004] Live water flushing also has certain limitations. Since it relies on people to observe the position of insulators and operate and control the water cannon for alignment, the operators are exposed to the working environment. As it is a live water flushing operation, in order to ensure the safety of the operators, high-quality water sources are required for live water flushing to ensure the resistivity and cleanliness of the water, which poses relatively high requirements for the selection and supply of water sources. When conducting water flushing operations in relatively harsh environments such as low temperature and heavy pollution, higher requirements are put forward for the protection of operators. At the same time, the working environment of the operators also needs to be improved. In addition, most of the existing catenary insulator water flushing vehicles are equipped with corresponding water flushing equipment on general flatbed trucks, without their own power, and need to be towed by a powered vehicle for operation. The operation control system is also relatively independent and not integrated into the control system of the entire vehicle, with a low degree of intelligence. This problem makes the water flushing operation vehicle relatively large in size, high in cost, and its application scenarios are restricted to a certain extent, seriously affecting the promotion and application speed. Utility Model Content

[0005] To solve the deficiencies existing in the current railway catenary insulator water flushing technology, the present utility model provides an integrated catenary insulator intelligent water flushing vehicle.

[0006] An integrated catenary insulator intelligent water flushing vehicle of the present utility model includes a rail vehicle, a cab, a power room, a water tank, a lidar, and an automatic water cannon. The front end of the rail vehicle is the cab, and a front lidar is arranged at the top of the front end of the cab; next to the cab is the power room; the water tank is arranged at the rear of the rail vehicle, an automatic water cannon is installed on the upper part of the water tank, and a rear lidar is installed at the rear end of the water tank; bogies are installed at the lower end of the rail vehicle, and encoders are respectively installed at the axle ends of the front and rear bogies.

[0007] Further, a driving console is arranged on the left side of the front end of the cab, and a water flushing console is arranged on the right side, and 1 crew seat is respectively arranged.

[0008] Further, a control cabinet and a battery pack are arranged at a position close to the wall in the power room; the control cabinet integrates the control modules of the rail vehicle and the water flushing system; the battery pack provides lighting for the whole vehicle and power for the control system and the servo system of the automatic water cannon. At the middle position of the power room, an engine is arranged, and the engine is connected to a hydraulic torque converter to provide driving power for the rail vehicle; a clutch is connected to the rear end of the hydraulic torque converter, and the power is transmitted to the pump station of the water flushing system through this clutch.

[0009] Further, the water tank is of a special-shaped structure, avoiding the position of the bogie, and the water tank sinks downward; the automatic water cannons are arranged at certain intervals on the center line directly above the water tank, and the automatic water cannons adopt a compact design, including a bottom gun body and a nozzle with a reduced height.

[0010] Furthermore, the rear lidar is installed on a base.

[0011] The beneficial technical effects of the present utility model are as follows:

[0012] (1) Aiming at the current situation that the catenary insulator water flushing vehicles are generally large in size, high in cost, and without their own power, the present utility model integrates the control systems of the rail vehicle and the water flushing device, realizing the integrated design of the vehicle and the water flushing system, and providing convenient conditions for the communication between the rail vehicle driver and the water flushing operation operator. The present utility model integrates the sunken water tank and the compact automatic water cannon, reducing the space required for the water cannon while lowering the overall center of gravity of the vehicle. The present utility model integrates the power systems of the rail vehicle and the water flushing system, effectively utilizing the engine power of the rail vehicle while reducing the engine set of the water flushing system, and correspondingly greatly reducing the required space. Through the above highly integrated design, without affecting the system functions, the space required for each component of the water flushing system is greatly reduced, realizing the miniaturization and compact design of the water flushing operation vehicle.

[0013] (2) Aiming at the current situation that during water flushing operations, the operator needs to operate the water cannon for alignment and flushing, the working environment of the operator needs to be improved under harsh working conditions, and the degree of automation of the flushing operation is not high, the present utility model uses lidar to identify and locate the target insulator, and completes the flushing through the automatic water cannon, greatly improving the degree of intelligence. The present utility model respectively sets a lidar at both the front and rear ends of the vehicle for identifying and locating the target insulator, which can effectively avoid the influence of the water mist generated during the flushing process on the positioning accuracy. At the same time, two encoders are installed at the axle ends of the vehicle to record the relevant data of the vehicle's running and assist the lidar in positioning. In this way, the target insulator can be accurately captured, located, and tracked. The present utility model uses an automatic water cannon to replace the traditional water cannon, and designs the water cannon in a compact form, reducing the weight and moment of inertia of the water cannon, enabling it to be installed in a relatively low space, and being able to perform real-time alignment and precise flushing of the target insulator under the guidance of the lidar. The entire process of the flushing operation does not require the participation of the operator and is automatically completed throughout, greatly improving the degree of intelligence.

[0014] (3)In view of the situation that the railcar and the water flushing system each have a set of power devices and there is a large amount of idle power in the power system, the utility model shares the two sets of power systems, realizing the maximum utilization of the output power of the power system. The engine of the railcar is used as the power source, and the power is transmitted to the railcar through a hydraulic torque converter to provide driving power for the vehicle. At the same time, the end of the hydraulic torque converter is connected to the pump station of the water flushing system, replacing the original generator set and motor. When the vehicle is running at high speed, the pump station is disengaged from the hydraulic torque converter through a clutch, and all the power of the engine is supplied to the power required for the vehicle to run. When entering the flushing operation area, the vehicle runs at low speed and at a constant speed, and the required power is greatly reduced. At this time, the pump station is connected to the hydraulic torque converter, so that the engine supplies both the driving power of the vehicle and the power required by the pump station, realizing power sharing. The shared power system designed by the utility model reduces the generator set of the pump station, correspondingly reduces the required space, effectively utilizes the engine power of the railcar, reduces the vehicle cost, improves the resource utilization rate, and provides favorable conditions for the compact integrated design of the vehicle.

Detailed Description of the Preferred Embodiment

[0020] The following further describes the utility model in detail with reference to the drawings and specific implementation methods.

[0021] An integrated catenary insulator intelligent water flushing vehicle of the utility model is as Figure 1As shown in the figure, it includes a rail vehicle 1, a cab 2, a power compartment 3, a water tank 4, a lidar, and an automatic water cannon. The lower end of the rail vehicle 1 is equipped with bogies and can run normally on railway tracks. Encoders 11 and 12 are respectively installed at the axle ends of the front and rear bogies to detect the rotation speed of the vehicle and record the number of rotations of the wheels, so as to obtain the current running speed and mileage of the vehicle, providing basic vehicle running parameters for the system to locate the target insulator. The front end of the rail vehicle 1 is the cab 2, which is the operation and control area of the entire water flushing vehicle. During the cleaning operation, both the operator and the rail vehicle driver are in the cab 2. At the top of the front end of the cab 2, a front lidar 51 is provided to identify the insulators in front of the vehicle during operation. When the target is identified, the target data is transmitted to the control system. Combining the vehicle running data of the encoders 11 and 12, the target insulator can be continuously tracked and located until the target insulator enters the effective flushing range to complete the flushing operation. Next to the cab 2 is the power compartment 3, where the driving power of the entire water flushing vehicle and the power required for water flushing are arranged. The water tank 4 is arranged at the rear of the rail vehicle 1 for loading the clean water required for the water flushing operation. An automatic water cannon 61 and an automatic water cannon 62 are installed on the upper part of the water tank 4. When the control system receives and processes the data of the target insulator, it is converted into a control instruction for the automatic water cannon, so that the automatic water cannon continuously aligns with the target insulator. When it enters the effective flushing range, the system automatically activates the water cannon for flushing operation. During the flushing process, the detection range of the front lidar 51 can no longer effectively cover the insulator being flushed currently. In order to maintain the continuity of the positioning data, a rear lidar 52 is installed at the rear end of the water tank 4 to continuously locate the target insulator during the flushing process until the target insulator is out of the effective flushing distance, completing the flushing operation of a single insulator.

[0022] Further, as Figure 2 shown, on the left side of the front end of the cab 2, a driving console 22 is provided, and on the right side, a water flushing console 21 is provided, and one crew seat 23 is respectively arranged. During the normal cleaning operation, the driver sits in the driving position on the left to complete the control of the rail vehicle operation, and the water flushing operation operator sits in the water flushing control position on the right to complete the monitoring of the water flushing operation. By integrating the water flushing control system into the rail vehicle operation control system, while maintaining the relative independence of the two systems, it also realizes an organic integration in the physical space, saving space. During the flushing operation, it improves the real-time and convenience of communication between crew members. Only one water flushing operator in the cab can complete the control of the water flushing system and the water flushing operation, greatly reducing the operation difficulty of the water flushing operation, reducing the number of operators, and greatly improving the working environment.

[0023] Further, as Figure 2As shown in the figure, a control cabinet 31 and a battery pack 32 are arranged near the wall inside the power compartment 3; the control cabinet 31 integrates the control modules of the rail vehicle and the water flushing system, realizing the integration of the control system. The battery pack 32 provides lighting for the whole vehicle and power for the control system and the servo system of the automatic water cannon. The rail vehicle and the water flushing system share a control cabinet 31 and a battery pack 32. In the middle position of the power compartment 3, an engine 33 is arranged. The engine 33 is connected to a hydraulic torque converter 34 to provide driving force for the rail vehicle 1; a clutch 35 is connected to the rear end of the hydraulic torque converter 34, and the power is transmitted to the pump station 36 of the water flushing system through this clutch 35, realizing power sharing.

[0024] Further, as Figure 3 shown, the water tank 4 has a special-shaped structure, avoiding the position of the bogie. The water tank 4 sinks downward. This structure moves the center of gravity of the entire water tank downward while keeping the load unchanged, enhancing the stability during vehicle operation. At the same time, enough space is left above the water tank for installing the automatic water cannon. A large amount of space originally used for installing and operating the water cannon is directly reduced, providing spatial guarantee for the compact integrated design of the whole water flushing. The automatic water cannon 61 and the automatic water cannon 62 are arranged at a certain interval on the center line directly above the water tank 4. During the flushing operation, the flushing water columns of the two water cannons wash the target from different angles without interference. The automatic water cannon 61 adopts a compact design. Since no operator is required for manual operation and its structure does not need to be designed according to the operating height of people, it can be designed to be shorter. By reducing the height of the bottom gun body 612, although the safety base position is raised, the effective safety distance between the gun nozzle 611 and the target insulator still meets the relevant standard requirements under the condition of ensuring the original functions unchanged, ensuring the electrical safety during the live flushing operation.

[0025] Further, as Figure 3 shown, the rear lidar 52 is installed on a base 521. By raising the base 521, the installation height of the lidar 52 can be adjusted to a suitable height to achieve the best recognition effect.

[0026] Further, as Figure 4As shown, the engine 33 is the only power source for the entire water flushing operation vehicle, which is directly connected to the torque converter to provide running power for the rail vehicle 1. When the rail vehicle 1 is traveling at high speed on the railway track, the clutch 35 is disconnected, and the power of the engine 33 is fully delivered to the vehicle as running power through the torque converter 34. After entering the flushing operation area, the rail vehicle 1 enters a uniform and slow running state. In addition to being delivered to the vehicle as running power, the power of the engine 33 also has a large amount of power redundancy in an idle state. At this time, the pump station 36 of the water flushing system just needs power input, so the clutch 35 is connected to the torque converter 34, and part of the power of the engine 33 is transmitted to the pump station 36 through the torque converter 34 and the clutch 35, driving the flushing system to perform flushing operations. Through this shared power system design, the effective power of the engine 33 is reasonably utilized, the generator set and motor components of the water flushing system are reduced, space is saved, and equipment costs are reduced.

[0027] The intelligent water flushing vehicle for contact network insulators of the utility model has a highly integrated design, which organically integrates the rail car and the water flushing system, and realizes the functions that conventionally require 2-3 vehicles to complete on one rail car. The control panel of the water flushing system is integrated into the control panel of the rail car, which not only facilitates operation and control, but also reduces the volume of the control module of the water flushing system. An automatic water cannon is placed on the water tank, and the placement space of the automatic water cannon overlaps with the space of the water tank, which greatly reduces the physical layout space required for the water flushing equipment. The power system in the water flushing system is shared with the traction power of the rail car, which reduces the generator set of the water flushing system and also greatly reduces the required space. Through the above-mentioned integrated design, the overall length of the contact network insulator water flushing operation vehicle has been greatly reduced.

[0028] The utility model is an intelligent automatic flushing device. A multi-threaded laser radar is arranged on the carport in front of the water flushing operation vehicle to capture the target insulator in front of the vehicle. After the insulator is captured, the position information of the target insulator is continuously sent to the automatic water cannon. At the same time, the vehicle operation data is obtained through the encoder installed on the vehicle axle for auxiliary positioning. When the vehicle runs to the effective flushing distance of the target insulator, the automatic water cannon, under the joint guidance of the laser radar and the encoder, always aims at the target insulator and starts the high-pressure water cannon in time to clean the insulator. During the cleaning process, in order to make the data obtained by the laser radar have higher accuracy, a laser radar is also arranged at the rear end of the vehicle to correct the possible errors in the data obtained by a single laser radar due to the influence of water mist. During the cleaning process, the participation of operators is not required throughout the whole process, and the intelligent flushing system automatically completes the flushing operation of the contact network insulators along the vehicle.

[0029] The utility model adopts a sunken water tank and a compact automatic water cannon. When the water tank is full, the water tank is the heaviest load of the whole vehicle. During operation, the water in the water tank may impact the vehicle due to jolts. To enhance the stability of the vehicle during operation, the water tank is designed in a sunken manner. Without affecting the water tank volume, the height of the water tank is greatly reduced, and the center of gravity of the whole water tank also decreases accordingly, making the vehicle more stable during operation. Since the automatic water cannon is used to replace the traditional manually operated water cannon, the operator is no longer exposed to the working environment, and the height of the water cannon no longer needs to be designed according to the general height of the operator. Therefore, the automatic water cannon can be designed in a compact form to reduce its overall height. After the water cannon is installed at the bottom of the water tank, the safety distance between the water cannon nozzle and the target insulator still meets the specification requirements for live water flushing. By stacking the compact automatic water cannon and the sunken water tank, while enhancing the vehicle stability, the space required for arranging the water flushing equipment is greatly reduced.

[0030] The utility model adopts a shared power system. The control systems of the railcar and the water flushing device, as well as the conventional energy consumption such as daily lighting, are supplied by a large storage battery. The power of the railcar is provided by a high-power engine, which drives a hydraulic torque converter to transmit power to the vehicle, enabling the vehicle to have the driving force. When the vehicle is performing water flushing operations, it travels at a low speed and at a constant speed, and the output power of its engine is much greater than the actual power required by the vehicle. Therefore, the utility model effectively utilizes the idle power of the engine. A water pump of the water flushing system is connected behind the hydraulic torque converter. When entering the flushing operation area, while the engine drives the vehicle to travel at a low speed, it also drives the water pump to perform flushing operations, realizing the power sharing between the railcar and the water flushing system. By adopting this shared power system, the generator set and the motor required for the conventional water flushing system are directly removed, greatly reducing the space occupied by the water flushing system, and at the same time making full and effective use of the engine power of the railcar.
