Description

Technical Field

[0001] This utility model relates to the field of track measurement technology, and in particular to an intelligent measurement trolley. Background Technology

[0002] In the daily operation and management of rail transit systems, accurate measurement of the track is crucial, as it relates to the safety, stability, and comfort of train operation. Taking electrified railways as an example, in order to effectively prevent pantograph-catenary faults and achieve safe and high-quality power supply, railway engineering and power supply departments always regard the railway standard line as a key bottom line. The accurate measurement of the railway standard line plays a decisive role in ensuring good coordination between the catenary and the pantograph and ensuring stable power transmission.

[0003] Traditional track measurement methods mainly include manual measurement and measurement with the help of professional measuring instruments. Manual measurement usually requires surveyors to carry measuring tools and perform measurement operations point by point along the track. This method is not only extremely inefficient and consumes a lot of manpower, material resources and time, but it is also very susceptible to interference from the subjective factors of the surveyors, making it difficult to guarantee the accuracy and reliability of the measurement data.

[0004] Currently, in order to improve the accuracy and efficiency of track measurement, track measurement trolleys are usually used for automatic measurement. Track measurement trolleys (track inspection trolleys) are mobile intelligent devices specifically used for detecting the geometric parameters of railway tracks. Through high-precision sensors and positioning systems, they can automatically detect the geometric state of the track, surface defects, and the status of auxiliary facilities, providing key data support for railway operation and maintenance.

[0005] Existing track measurement trolleys are usually electrically driven. Before measurement, the trolley's power supply battery needs to be charged. However, in practical applications, the charging time is too long and greatly affects the measurement efficiency. In addition, the current trolleys are usually fixed inside the vehicle body, making it difficult to carry out more convenient battery swapping operations. Utility Model Content

[0061] The specific embodiments of this utility model are described in detail below, but it should be understood that the protection scope of this utility model is not limited to the specific embodiments.

[0062] like Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 7 As shown, this embodiment provides an intelligent measuring trolley, including a device mounting plate 1. A protective shell 2 is fixedly connected to the outer side of the device mounting plate 1 by multiple bolts, which is configured as the protective structure of the measuring trolley. Multiple curved brackets 3 are provided on the lower surface of the device mounting plate 1, and each of the multiple curved brackets 3 is provided with a measuring wheel 4 at its bottom end. A battery box 5 is fixedly connected to the upper inner surface of the device mounting plate 1. The battery box 5 is configured as a hollow structure with openings at both ends. A pull-out box 6 is slidably connected to the lower inner surface of the battery box 5. The pull-out box 6 is connected to a pull-out assembly for pulling out the pull-out box 6. A battery body 7 is provided inside the pull-out box 6. A through-type operation port 8 is opened on the front surface of the protective shell 2 and inside the battery box 5. A movable plate 9 is provided inside the operation port 8. The rear surface of the movable plate 9 is fixedly connected to the front surface of the pull-out box 6. When the pull-out box 6 enters the battery box 5, the movable plate 9 is in the state of being embedded in the operation port 8.

[0063] Furthermore, it should be noted that both the battery body 7 and the ranging wheel 4 in this embodiment adopt existing technologies. This embodiment does not limit their specific models and structures, as long as they meet the actual application requirements.

[0064] Specifically, when the intelligent measuring trolley is working, the battery body 7 is placed in the pull-out box 6. It can be pulled out or pushed in from the battery box 5 through the operating port 8 via the movable plate 9, which facilitates installation and replacement and provides power for the trolley's operation. The equipment mounting plate 1 supports the core components, and the protective shell 2 is connected to the equipment mounting plate 1 by bolts, providing protection for the internal components and resisting external impacts, dust, and moisture corrosion. Multiple curved brackets 3 suspend the measuring wheels 4 below the equipment mounting plate 1. When working, the measuring wheels 4 roll along the track, and the pulse signals generated by their rotation are used to calculate the travel distance and speed, realizing continuous measurement of the track. As the measuring trolley moves along the track, it can simultaneously collect data such as track geometry parameters and line status, effectively replacing the cumbersome process of manual measurement and the complex operation of professional measuring instruments, reducing manpower input and measurement time, avoiding human interference, and operating stably in different environments, improving measurement efficiency and accuracy, reducing labor intensity, and ensuring the efficient and accurate conduct of rail transit measurement work.

[0065] like Figure 1 , Figure 2 and Figure 6 As shown, mounting bases 10 are symmetrically fixedly connected to the upper surface of the protective housing 2. The inner sidewalls of the two mounting bases 10 are threaded with screws 11, and the top ends of the two screws 11 are fixedly connected with antennas 12.

[0066] Before using the intelligent measurement trolley, screw the two screws 11 into the inner wall of the mounting base 10 through the threaded connection, and securely install the antenna 12 on the upper surface of the protective housing 2. Ensure that the antenna 12 is tightly connected and in normal working condition. If the antenna 12 is not installed, the power of the radio frequency module inside the trolley will be too high when working, which can easily cause it to burn out. After the antenna 12 is installed, use the movable plate 9 through the operation port 8 to pull out the pull-out box 6 from the battery box 5, put the battery body 7 into the pull-out box 6, and then push it smoothly into the battery box 5 to complete the battery installation and provide power for the operation of the trolley.

[0067] During operation, antenna 12 is responsible for receiving and transmitting signals, communicating in real time with external control systems or data centers, uploading measurement data, receiving instructions, and ensuring that the trolley runs according to the predetermined program and route, effectively improving the reliability and continuity of measurement work.

[0068] It should be noted that the antenna 12 in this embodiment adopts existing technology, and this embodiment does not limit its specific model and structure, as long as it meets the actual application requirements.

[0069] like Figure 1 and Figure 2 As shown, a lifting handle 13 is fixedly connected to the upper surface of the protective housing 2 and located between the two antennas 12;

[0070] In practical work, when it is necessary to place the measuring trolley at the starting measurement point of the track, or to transfer it to the next measurement area after completing a section of track measurement, the operator can directly hold the lifting handle 13 to easily lift or move the trolley, improving the safety and comfort of handling, making the operation of the measuring trolley more flexible and efficient, and enhancing the practicality and ease of use of the equipment.

[0071] like Figure 1 , Figure 3 , Figure 4 and Figure 7 As shown, the pull-out assembly includes a locking mechanism. When the movable plate 9 is inserted into the operating port 8, the locking mechanism is used to lock and fix the movable plate 9. The locking mechanism includes through-hole fixing holes 14 opened on the left and right sides of the inside of the battery box 5. The front surface of the movable plate 9 is symmetrically provided with actuating grooves 15. Limiting rods 16 are symmetrically fixedly connected inside the two actuating grooves 15. Actuating plates 17 are slidably connected inside the two actuating grooves 15. The inside of the two actuating plates 17 are slidably connected to the outer walls of the multiple limiting rods 16 respectively. Springs 18 are fitted on the outer walls of rod 16. The two ends of multiple springs 18 are fixedly connected to the opposite sides of two actuating plates 17 and the opposite sides of the interior of two actuating grooves 15, respectively. Positioning rods 19 are fixedly connected to the opposite sides of the two actuating plates 17. The opposite ends of the two positioning rods 19 pass through two fixing holes 14, and the axis of the positioning rod 19 is on the same horizontal plane as the axis of the fixing hole 14. When the movable plate 9 is inserted into the operating port 8, the springs 18 push the positioning rods 19 into the fixing holes 14 to lock the movable plate 9.

[0072] As one possible implementation of this embodiment, the toggle plate 17 is configured to extend outward from the toggle slot 15 in a direction away from the battery box 5, so as to facilitate the operator toggling it.

[0073] When installing the battery body 7, first place the battery into the pull-out box 6. Then, grasp the two actuating plates 17 on both sides and pull them in opposite directions against the elastic force of spring 18. At this time, the positioning rod 19 moves with the actuating plate 17 and is pulled out from the fixing hole 14. The movable plate 9 can slide freely in the operating port 8. Push the pull-out box 6 together with the battery body 7 into the battery box 5. When the movable plate 9 reaches the appropriate position, release the actuating plate 17. Under the elastic force of spring 18, the actuating plate 17 drives the positioning rod 19 to move in the opposite direction, so that the positioning rod 19 passes through the fixing hole 14. This fixes the movable plate 9, which in turn secures the battery body 7 inside the pull-out box 6, forming a stable mechanical locking structure. Even if the intelligent measuring trolley encounters bumps or vibrations while traveling on the track, the battery body 7 will not loosen or shift, ensuring stable battery power supply and preventing situations such as poor contact or power outages caused by battery shaking. This reduces the impact of unstable power supply on the accuracy of measurement data and the reliability of equipment operation. At the same time, this convenient installation and fixing method allows staff to quickly install and remove the battery, improving the convenience of equipment use and work efficiency.

[0074] like Figures 3-5 As shown, the pull assembly also includes: a spring component, which is disposed at the rear end of the battery box 5 away from the operation port 8. When the pull box 6 enters the battery box 5, the spring component is compressed and stores force to push the pull box 6 out of the battery box 5.

[0075] Specifically, the elastic assembly includes elastic boxes 21 symmetrically fixed to the rear surface of the battery box 5. Sliding plates 22 are slidably connected inside the two elastic boxes 21. Protruding plates 23 are fixedly connected to the front surfaces of the two sliding plates 22. The protruding plates 23 are slidably arranged in the box wall of the elastic box 21 against the battery box 5. The rear surfaces of the two sliding plates 22 are respectively fixedly connected to the rear surfaces of the two elastic boxes 21. Connecting plates 25 are symmetrically fixedly connected to the rear of the upper surface of the pull-out box 6. The front surfaces of the two protruding plates 23 are respectively in contact with the rear surfaces of the two connecting plates 25.

[0076] It should be further explained that when the battery body 7 needs to be removed, the positioning rod 19 is disengaged from the fixing hole 14 by moving the actuating plate 17, thus releasing the fixation of the movable plate 9. At this time, the pull-out box 6 can move freely. Since the connecting plate 25 symmetrically arranged at the rear of the upper surface of the pull-out box 6 is in contact with the protruding plate 23, and the protruding plate 23 is connected to the elastic box 21 through the sliding plate 22, the second spring 24 is in a compressed state and stores elastic potential energy. When the movable plate 9 is released, breaking the static balance of the pull-out box 6, the second spring 24 releases its elastic potential energy, pushing the sliding plate 22 to slide forward in the elastic box 21. The sliding plate 22 drives the protruding plate 23 to move forward, thereby pushing the connecting plate 25, which is in contact with the protruding plate 23, forward. This design allows the pull-out box 6, along with the battery body 7, to automatically pop out partially from the battery compartment 5, making it easier for operators to fully remove the battery body 7. This significantly reduces the difficulty of removing the battery body 7 and avoids situations where the compact internal structure of the battery compartment 5 and high pulling resistance make it difficult for operators to remove the battery, thus improving battery replacement efficiency. At the same time, the elasticity of spring 24 ensures that the pull-out box 6 pops out smoothly, preventing damage to the battery body 7, pull-out box 6, and battery compartment 5 that may be caused by violent pulling. This ensures the integrity and lifespan of the equipment, enhances the user-friendliness of the equipment, and makes battery replacement easier and more convenient for operators, reducing workload and improving the overall operating experience and work efficiency.

[0077] like Figure 2 As shown, a heat dissipation mesh 20 is embedded in the rear surface of the protective housing 2;

[0078] Specifically, when the trolley is running, the various electronic components on the equipment mounting plate 1 will generate heat. If the heat accumulates, it will affect the performance of the equipment and even shorten its service life. The heat dissipation mesh 20 can form a convection channel between the cold air outside and the hot air inside. The internal heat is conducted to the heat dissipation mesh 20 through the air and then dissipated to the external environment through the mesh. The design ensures that the electronic components work at a suitable temperature and maintains the accuracy and stability of the measurement data.

[0079] like Figures 1-3 As shown, a connecting box 26 is integrally formed on the upper surface of the battery box 5. The top of the connecting box 26 extends to the top of the protective housing 2. A fan assembly 27 is fixedly connected to the upper surface of the protective housing 2 and above the connecting box 26 by bolts.

[0080] It should also be noted that when the intelligent measuring trolley is running, the battery body 7 and its internal components generate heat. After the fan assembly 27 is started, it draws air outward to create negative pressure, which draws the hot air in the battery box 5 upward through the connecting box 26. Meanwhile, the cold air from the outside enters from the heat dissipation mesh 20 on the rear surface of the protective shell 2, flows through the surrounding components of the equipment mounting plate 1, carries away the heat, and is then discharged by the fan assembly 27 through the connecting box 26. Through forced convection cooling, the battery temperature can be quickly reduced, avoiding performance degradation or failure due to overheating, ensuring stable operation of the internal equipment of the measuring trolley, extending the service life of the equipment, and providing continuous power for accurate measurement work.

[0081] It should be noted that the fan assembly 27 in this embodiment adopts existing technology. This embodiment does not limit its specific model and structure, as long as it meets the actual application requirements.

[0082] The above-disclosed embodiments are only a few specific examples of the present utility model. However, the embodiments of the present utility model are not limited thereto. Any changes that can be conceived by those skilled in the art should fall within the protection scope of the present utility model.
