Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of railway line inspection, in particular to a magnetic adsorption railway monorail carrier, and particularly to a carrier capable of walking on a single track by using the principle of magnetic adsorption. BACKGROUND

[0002] In the railway line inspection work, track carriers are often used to carry detection equipment to complete the inspection work. Double-track carriers need to span two rails, and the size and weight of the carrier are difficult to reduce, which brings difficulties to the transfer operation. The monorail carrier is a carrier capable of walking on a single track, and does not need a connecting structure to span the track, which can greatly improve the portability and carrying efficiency of the carrier.

[0003] Since the outer contour of the railway track does not provide a suitable position for the claw buckle, it is difficult to ensure that the monorail car does not overturn during track travel, and the mechanical fixing structure will interfere with the turnout when the monorail car passes through the turnout, resulting in the carrier being unable to pass smoothly. SUMMARY

[0004] The purpose of the present application is to overcome the shortcomings of the prior art, and to provide a magnetic adsorption railway monorail carrier. The monorail car body gravity center projection position is designed outside the rail surface, and the torque between the magnetic adsorption force, the external gravity center gravity and the rail surface support reaction force is used to offset each other, so as to realize the self-balancing of the carrier. At the same time, since the rail surface support reaction force is a force generated with the main force, the carrier does not need to rely on other auxiliary means, and the change of gravity within the limit adsorption force of the magnetic adsorption force can be balanced in real time. In addition, the magnetic adsorption structure on the side of the car body can also provide guidance for the car body passing through the railway turnout.

[0005] The purpose of the present application is achieved by the following technical solution:

[0006] A magnetic adsorption railway monorail carrier can be carried on a single track and walk. The monorail carrier includes a carrier table, a wheel and a guide wheel. The wheel is installed on one side of the carrier table along the line direction and in contact with the top surface of the single track. The guide wheel is installed on the side of the carrier table and in contact with the side surface of the single track. The monorail carrier is characterized in that the monorail carrier body gravity center projection position is located outside the rail surface of the single track. Magnetic adsorption modules are arranged on the top surface and one side surface of the carrier table, and the magnetic adsorption modules can generate magnetic adsorption force on the single track.

[0007] The monorail carrier body gravity center projection position is located away from the side of the guide wheel.

[0008] The magnetic adsorption module generates magnetic adsorption force on the single track, which meets the need of balancing the monorail carrier with external gravity center on the single track.

[0009] The magnetic adsorption module is a permanent magnet or an electromagnetic body which can be controlled to open and close.

[0010] The advantages of the present application are: real-time dynamic balance of the monorail carrier on the single track is achieved, the stability of the monorail carrier is ensured, especially the stability when the monorail carrier walks on the single track; the railway turnout can be smoothly and stably passed through, further ensuring the continuity and accuracy of the inspection work; the implementation of various detection items commonly used in the current railway inspection is facilitated, and the detection precision and accuracy are improved; the structure is simple and reasonable, the device is small and light, easy to use, convenient to carry and transport, and suitable for promotion.

[0015] The features of the present application and other related features are further described in detail below by embodiments combined with the drawings, so as to facilitate the understanding of the same by the skilled in the art:

[0016] As Figures 1-4 shown, the various marks in the figure respectively represent: a wheel 1, a guide wheel 2, a carrier table 3, a top surface magnetic adsorption module 4, a side surface magnetic adsorption module 5, a rail 6; a side surface magnetic adsorption guide structure 3-1.

[0017] Embodiment: as Figures 1 to 4 shown, the magnetic adsorption monorail carrier in the present embodiment includes a vehicle body and a magnetic adsorption module, wherein the vehicle body is stably carried on the single rail 6 and walks along the rail 6, and the magnetic adsorption module is used to provide the required stable force when the vehicle body is carried on the monorail, ensuring the stability of the vehicle body.

[0018] Specifically, the vehicle body is composed of a carrier table 3, a wheel 1 and a guide wheel 2. Among them, the wheel 1 is installed at the top surface position of the carrier table 3 and the wheel 1 is in contact with the top surface roller of the rail 6; the vehicle body can walk on the rail 6 through the driving of the wheel 1. The guide wheel 2 is installed at the side surface position of the carrier table 3 and is in contact with the side surface roller of the rail 6, realizing the guidance of the vehicle body when walking.

[0019] The magnetic adsorption module includes a top magnetic adsorption module 4 and a side magnetic adsorption module 5 arranged on the top surface and side surface of the object table 3 respectively. The top magnetic adsorption module 4 is arranged above the rail 6 and close to the top surface of the rail 6 to form a non-contact magnetic adsorption, and the side magnetic adsorption module 5 is arranged on one side of the guide wheel 2 and close to the side surface of the rail 6 to form a non-contact magnetic adsorption.

[0020] In the embodiment, the top magnetic adsorption module 4 and the side magnetic adsorption module 5 are both composed of permanent magnets. In some cases, the top magnetic adsorption module 4 and the side magnetic adsorption module 5 can also use controllable electromagnetic bodies, that is, when the vehicle body needs to work, the electromagnetic body is powered to generate a magnetic adsorption force; after the work is completed, the electromagnetic body is powered off to lose the magnetic adsorption force, which is convenient for the vehicle body to go up and down the rail.

[0021] As shown in Figure 2 , the gravity center of the monorail vehicle in the embodiment is projected outside the top surface area of the rail 6, and is away from the contact surface between the side guide wheel 2 and the rail 6 (also the surface where the side magnetic adsorption module 5 is located), and at the same time, it goes beyond the contact point between the wheel 1 and the rail 6. Therefore, the direction in which the vehicle body in the embodiment can overturn is only the side where the gravity center is located. Vehicle-mounted instruments or articles can be installed on the object placing area on the object table 3, so that the gravity center of the vehicle body remains unchanged on the same side.

[0022] After the vehicle body in the embodiment is carried on the rail 6, the top magnetic adsorption module 4 and the side magnetic adsorption module 5 are close to the top surface and the side surface of the rail 6 respectively, and generate a magnetic adsorption force to adsorb the vehicle body on the rail 6.

[0023] Because of the existence of the contact surface reaction force on the wheel, the torque generated by the magnetic force and the torque generated by the gravity to make the vehicle body overturn and the torque generated by the contact surface reaction force are counteracted, so the vehicle body in the embodiment can always be adsorbed on the rail 6.

[0024] Specifically, as shown in Figure 2 , the vehicle body will receive the following five forces: the gravity G of the vehicle body, the top magnetic force F1, the side magnetic force F2, the top reaction force F ’ 1, and the side reaction force F ’ 2. Among them, the gravity G of the vehicle body, the side magnetic force F2, and the side reaction force F ’ 2 will take point P as the fulcrum to generate counterclockwise torque respectively. And the top magnetic force F1 and the side magnetic force F2 will take point P as the fulcrum to generate clockwise torque respectively.

[0025] Because of the existence of the top reaction force F ’ 1 and the side reaction force F ’The resultant torque generated by 2 is the opposite torque formed by the resultant torques of the top magnetic attraction F1, the side magnetic attraction F2, and gravity G. Therefore, the two are equal in magnitude and opposite in direction. As a result, the overall resultant torque of the car body is 0, so it can always maintain a steady state on a single steel rail 6 without deflection or falling.

[0026] In this embodiment, as long as the torque generated by the gravity of the vehicle's center of gravity does not exceed the maximum torque generated by the magnetic force of the top magnetic adsorption module 4 and the side magnetic adsorption module 5, the vehicle body will not deflect on the rail 6 or fall off the rail 6, and it can maintain stable monorail travel.

[0027] Combination Figure 1 and Figure 4 As shown, the side magnetic adsorption module 5 and guide wheel 2 are designed on only one side below the platform 3, which can avoid collisions and interference when passing through railway switches, ensuring that the car body in this embodiment can pass through the railway switches smoothly. At the same time, when the car body passes through the railway switches, the side magnetic adsorption module 5 acts as the side magnetic adsorption guide structure 3-1, providing guidance for the movement of the car body.

[0028] like Figure 2 As shown, in this embodiment, the vehicle's center of gravity projection position is designed on the outer side of the rail surface of rail 6. Therefore, the platform 3 has a longer extension surface projected towards the center of gravity projection position, which facilitates changing the installation position of vehicle-mounted instruments and equipment such as cameras, laser rangefinders, and acoustic wave detectors. This allows the measuring equipment to be closer to the target being measured, thereby improving detection accuracy and precision. Applications include railway trackside equipment damage detection, signal equipment clearance measurement, and platform clearance measurement. Taking platform clearance measurement as an example, due to the structure of the platform 3, common infrared platform clearance measuring devices can be installed closer to the platform, significantly shortening the relative distance between the measuring device and the platform, thus effectively improving the accuracy of clearance measurement.

[0029] Although the above embodiments have described the concept and embodiments of the present invention in detail with reference to the accompanying drawings, those skilled in the art will recognize that various improvements and modifications can still be made to the present invention without departing from the scope of the claims, and therefore will not be elaborated here.
