Description

Technical Field

[0001] The present application relates to the field of railway machinery design and manufacturing, and in particular to a track flaw detection vehicle. Background Art

[0002] Rail damage refers to rail breakage, rail cracks and other defects that affect and limit the performance of rails during use. It is necessary to detect the damage in two rails on the railway line and analyze, process and record the detection results, so that the damage inside the rails can be clearly seen in the image.

[0003] The existing rail flaw detection scheme usually adopts the form of a power car and a test car combined into a flaw detection vehicle group, with a detection speed of about 80km / h. The power car and the test car are connected to form a vehicle group through an automatic coupler and a folding shed windshield. The test car is equipped with a set of surface scratch and wave wear detection devices, which can detect the surface scratch and wave wear of the rail. The power car is mainly used to provide power source for the flaw detection system, and is equipped with a driver's room, machine room, maintenance room, kitchen and toilet, etc.

[0004] As for the bearing mode of the undercarriage system, it can be basically divided into two types: flaw detection trolley and bogie. For example, Beijing Metro adopts the flaw detection trolley mode, while Shanghai Metro adopts the bogie bearing mode. The advantage of the trolley type is that it has a large maintenance space, but it has high requirements for the stability and centering of the trolley. When flaw detection work is required, the trolley is placed on the track. The disadvantage is that it is difficult to accurately place the flaw detection trolley on the track.

[0039] In order to make the technical solutions and advantages in the embodiments of the present application more clearly understood, the exemplary embodiments of the present application are further described in detail below in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present application, rather than an exhaustive list of all the embodiments. It should be noted that the embodiments in the present application and the features in the embodiments can be combined with each other without conflict.

[0040] In the process of realizing the present application, the inventors found that the existing rail flaw detection operations are usually carried out by combining an inspection vehicle and a power vehicle, and the double-vehicle operation mode has high manufacturing and use costs.

[0041] For the above questions, see Figure 1 In an embodiment of the present application, a track flaw detection vehicle is provided, in which a single-section vehicle body structure is used as the vehicle body of the whole vehicle, and a number of interconnected functional rooms are arranged in the vehicle body, and different functional equipment is integrated and distributed in different functional rooms to realize the two functional combinations of track travel and flaw detection. The flaw detection vehicle uses a walking system that can travel in both directions to carry the vehicle body to move along the track; the walking system is powered by a power system. As a track flaw detection function, the flaw detection vehicle includes a flaw detection system, which mainly includes a flaw detection device 12, which is arranged at the bottom of the driven bogie and is used to perform flaw detection on the track. The power system and the walking system are combined to realize the movement of the vehicle body. On this basis, a flaw detection system is added to achieve the working purpose of both movement and flaw detection with a single vehicle body.

[0042] On the basis of the above implementation scheme, the first driver's cab 23 and the second driver's cab 15 are respectively arranged at both ends of the vehicle body, and each functional room is arranged between the first driver's cab 23 and the second driver's cab 15. A passage that runs through the entire vehicle body is reserved between the two driver's cabs to facilitate the staff to walk. The two driver's cabs are used for different driving directions of the vehicle. Each driver's cab is equipped with a driving platform, monitoring equipment, a keypad of the flaw detection system, a seat, and a fire extinguisher. The driving platforms of the first driver's cab 23 and the second driver's cab 15 have an interlocking control function, and the two driver's cabs cannot be operated at the same time to prevent misoperation and improve the safety of the equipment.

[0043] On the basis of the above implementation scheme, the functional rooms in the vehicle body include a power room 21 as a space for placing power-related equipment. The power room 21 is provided with an engine-gearbox combination 6 as the main power output component. The engine-gearbox combination 6 outputs power to the power bogie 3 of the walking system through the transmission shaft 4, thereby pulling the whole vehicle to run, and needs to meet the traction operation requirements of the steep slope. The gearbox uses a hydraulic gearbox. The engine and gearbox combination 6 is arranged at the lower part of the vehicle body corresponding to the power room 21, and is one of the external layout components of the whole vehicle.

[0044] On the basis of the above implementation plan, Figure 3As shown, a power distribution cabinet and an auxiliary generator set 211 are installed in the power room 21, and the strong and weak electricity are arranged separately to ensure the safety of electricity use. The auxiliary generator set 211 uses a self-contained small diesel engine-type power generation equipment to supply power to auxiliary equipment such as air conditioning and lighting. In order to ensure the power generation effect, the auxiliary generator set 211 selected in this scheme is relatively large in size. It is set along the length direction of the vehicle body during installation, and walking passages are reserved on both sides of the auxiliary generator set 211. Its heat dissipation port guides the hot air to the air outlet side of the power room 21 through the air guide structure.

[0045] Based on the above implementation scheme, see Figure 2 The power room 21 is centrally arranged, including auxiliary generator set 211, engine 212, hydraulic gearbox 213, radiator 214, brake valve group 215, hydraulic oil tank 216, muffler 217 and other components. The centralized arrangement is convenient for management and maintenance, and optimizes the heat dissipation of each system. The engine 212 and the hydraulic gearbox 213 are combined to form an engine and gearbox combination 6. The engine and gearbox combination 6 is controlled by the first driver's cab 23 or the second driver's cab 15, and an operating gear control handle corresponding to the flaw detection operation state is set on the control console of the driver's cab.

[0046] On the basis of the above implementation scheme, the frame 13 at the position of the power room 21 is provided with an opening, and the opening forms the bottom air inlet channel 218 of the power room 21. The bottom air inlet channel 218 is formed by means of the opening of the frame and the gap between the engine 212. The reserved engine installation position on the frame needs to be opened. After the engine is installed, there is still a large gap at the edge, which can be used for air intake, thereby forming the air inlet channel 218. The engine and gearbox combination 6, the auxiliary generator set 211, and the muffler 217 are all arranged in the middle area of ​​the vehicle body and arranged along the length direction of the vehicle body. The radiator 214 is located at a side wall of the power room 21, which serves as an air outlet for heat dissipation of the power room 21. The hydraulic oil tank 216 and the radiator 214 are located on the same side of the vehicle body. The side wall of the power room 21 away from the radiator 214 is the air inlet. The shutter 19 is set at the air inlet position, so that the power room 21 forms a heat dissipation structure with air inlets in two directions, bottom and side, and a side air outlet. It meets the heat dissipation requirements when the vehicle is running. The brake valve group 215 is arranged inside the vehicle to improve the safety and maintainability of the equipment. At the same time, as the air inlet side, a passage is reserved between the equipment inside the power room 21 for workers to walk. Railings 219 are set in the passage and near the equipment for safety protection. The auxiliary generator set 211 is set near the bolster 210.

[0047] On the basis of the above implementation scheme, a heat dissipation duct 220 is provided for the heat dissipation of the auxiliary generator set 211. The heat dissipation port of the auxiliary generator set 211 is located inside the heat dissipation duct 220, and the heat is also dissipated through the air outlet of the power room 21. The heat dissipation duct 220 is formed by an air guide cover, a grille is installed at the end of the air guide cover, and a drainage hole is arranged at the bottom to drain rainwater.

[0048] In this solution, multiple cooling fans are provided, including a cooling fan for the hydraulic transmission 213, a high-temperature water cooling fan for the engine 212, and a hydraulic cooling fan. Hydraulic power is provided through the PTO port of the hydraulic transmission 213, and power is provided for each cooling fan through the hydraulic transmission 213.

[0049] On the basis of the above implementation scheme, the power room 21 is adjacent to one of the driver's cabs, and the other side of the power room 21 is the maintenance room 17, in which a water tank, a temperature control cabinet, a water pump cabinet and an operating table are arranged. The water tank can store at least 2000L of water, and a nozzle is arranged at the lower part of the vehicle body, and the nozzle is arranged toward the track. The nozzle is connected to the water tank through a pipeline to form a spray device for flaw detection. During the flaw detection operation, the rail surface is sprayed by the spray device to achieve the purpose of cleaning the rail surface, so that the flaw detection is not affected by oil and other impurities, and the accuracy of the detection is improved. The water pump cabinet is used to pressurize the water for spraying to improve the efficiency of rail surface cleaning.

[0050] The temperature control cabinet is used to adjust the temperature of the coupling fluid in the probe wheel, so that the coupling fluid is in a relatively stable temperature state, which can improve the detection accuracy. The probe wheel is a component of the existing flaw detector and will not be described here. The operating table is used to place small tools and their maintenance equipment. A tool cabinet is set under the operating table. When not in use, the tools and maintenance equipment can be fixed in the tool cabinet to provide convenience for the operator.

[0051] On the basis of the above implementation plan, an inspection and flaw detection room 16 is set between the maintenance room 17 and the second driver's cab 15 as a space for placing flaw detection related equipment. It is equipped with an operating table, a flaw detection cabinet, and a PLC cabinet to control the operation of the flaw detection system. The operator can perform interface operations on the operating table and provide action and control signals through the PLC cabinet to control the flaw detection device 12 under the car to perform flaw detection operations. The flaw detection device 12 performs flaw detection on the internal damage of the rails. In addition, a surface detection device and an auxiliary flaw detection device 13 are configured to perform surface detection. The auxiliary flaw detection device 13 can be set on the lower side of the car body, or under one of the bogies of the car body. The flaw detection device 12 and the auxiliary flaw detection device 13 are combined to provide an overall situation of the damage, which is analyzed through the flaw detection control system and forms a damage report.

[0052] On the basis of the above implementation scheme, the traveling system includes a power bogie 3 and a driven bogie 11 arranged on the lower side of the frame 13; wherein the power bogie 3 is linked with the engine-transmission combination 6 through the transmission shaft 4; and the flaw detection device 12 is arranged on the driven bogie 11.
