Description

Technical Field

[0001] This utility model belongs to the field of rail transit inspection, specifically relating to a rail transit carbon skateboard inspection device. Background Technology

[0002] Safety is an eternal theme for railways. Railway line equipment is the power transmission equipment of the railway transportation industry. Maintaining the integrity and quality balance of the line equipment, ensuring the safe, stable, and uninterrupted operation of trains at regular speeds, and extending the service life of the equipment as much as possible are important responsibilities of railway power supply departments. Therefore, the proper maintenance of transmission lines and ensuring their quality are prerequisites for ensuring the safe production of power supply departments and the foundation for ensuring the safety of urban subway transportation.

[0003] The pantograph, as an electrical device that obtains power from the overhead contact line in rail transit vehicles, is generally installed on the roof of locomotives or EMUs and is an important component of the contact line. The pantograph consists of components such as carbon sliding plate, upper frame, lower arm, base frame, lifting spring, transmission cylinder, and support insulator. Among them, the carbon sliding plate is the part that directly contacts and conducts electricity with the high-voltage line. With the frequent sliding contact between the high-speed sliding plate and the high-voltage cable, the carbon sliding plate is constantly worn. When the wear reaches a certain level, it will inevitably bring huge hidden dangers to the safety of track operation. Therefore, it is necessary to detect the wear of the carbon sliding plate during the maintenance of relevant vehicles.

[0004] There are many devices for detecting the wear condition of carbon skateboards, such as... Figure 1 As shown, the detection device includes a housing, inside which a detection device for detecting carbon slide plates is installed. Two locking mechanisms are directly disposed at the bottom of the housing, extending along the length of the carbon slide plate. These locking mechanisms are used to position and lock or release the housing as it moves on the carbon slide plate. Figure 2 As shown, the locking mechanism has a contact surface that is slidably mounted on the carbon slide plate;

[0005] In the above structure, because the locking mechanism is directly fixed to the housing, and the two locking mechanisms are set at the bottom of the housing along the length of the carbon slide plate, the housing only performs detection along one carbon slide plate and along the length of the carbon slide plate. As a result, the detection efficiency is low and the detection coverage is small for a period of time, that is, the detection effect is poor. Utility Model Content

It should be noted that the description of these embodiments is for the purpose of helping to understand this utility model, but does not constitute a limitation on this utility model.

[0052] Example 1

[0053] like Figure 3-7 As shown, a rail transit carbon sliding plate detection device, the carbon sliding plate 2 having a length direction and a width direction, includes:

[0054] The housing 3 is positioned along the length of the carbon slide plate 2;

[0055] Two movable structures 1 are respectively installed at both ends of the lower surface of the housing 3 along the length direction. Specifically, the sliding block 2 on the movable structure 1 is fixed to the housing 3 by screws; the walking mechanism is installed inside the housing 3.

[0056] The wear detection module is installed in the walking mechanism and is used to detect the wear information of the moving structure 1 on the top surface of the carbon slide plate 2. It should be noted that the wear detection module detects the wear information of the moving structure 1 on the top surface of the carbon slide plate 2 as the walking mechanism moves inside the housing 3.

[0057] The stroke detection module is installed inside the housing 3 and is used to detect the stroke information of the wear detection module along the length direction of the carbon slide plate 2.

[0058] A touch screen is mounted on the surface of the housing 3 and is aligned with the length direction. The stroke detection module, the wear detection module, and the touch screen are all connected to the processor to receive stroke information, control the moving structure 1 to drive the wear detection module to move along the length direction of the carbon slide plate 2, and display the detection results of part or all of the length on the touch screen. The abnormal information displayed on the touch screen corresponds one-to-one with the actual position of the abnormal information on the carbon slide plate 2.

[0059] The two moving structures described above are jointly mounted on several parallel carbon sliding plates 2. In this embodiment, at least two parallel carbon sliding plates are detected, including:

[0060] The guide rail mechanism 11 is rolled along its length onto at least two parallel carbon slide plates 2. Specifically, the guide rail mechanism 11 includes:

[0061] Guide rail base 112 is set along the width direction.

[0062] Roller 113 is rotatably mounted on guide rail seat 112, and the circumferential surface of roller 113 makes rolling contact with all carbon slide plates 2;

[0063] A roller 113 is rotatably mounted on the guide rail base 112, and the circumferential surface of the roller 113 contacts the carbon slide plate 2; and the guide rail base 112 is provided with an indicator line 13 along the width direction;

[0064] The guide rail seat 112 has a placement cavity that is open in the vertical direction, and the roller 113 is rotatably installed in the placement cavity;

[0065] The guide rail mechanism 11 has a locking component 114, which clamps or releases the carbon slide plate 2. Specifically, the locking component 114 includes:

[0066] The transmission screw 1141 is arranged along the width direction and has two sets of threads on its circumferential surface. The two sets of threads are located at both ends of the transmission screw 1141, and each set of threads is a forward thread and a reverse thread. They are threaded onto the guide rail seat 112 through the forward thread and the reverse thread, respectively. The main feature is that a bearing is set in the placement cavity on the guide rail seat 112. The smooth surface on the transmission screw 1141 cooperates with the bearing. Specifically, the circumferential surface at the middle position of the transmission screw 1141 is a smooth surface. Each roller 113 has a hollow interior that extends along the width direction. The smooth surface is inserted into the hollow interior, and the two ends of the roller 113 are rotatably sleeved with the smooth surface.

[0067] Two sets of locking elements 1143 are located at both ends of the transmission screw 1141, and each set of locking elements 1143 is threaded onto the forward thread and the reverse thread, and there is a gap between each set of locking elements 1143 and the guide rail seat 112 along the length direction; each set of locking elements 1143 together clamps or releases the carbon slide plate 2.

[0068] There are multiple rollers 113. One roller 113 is rotatably sleeved on the transmission screw 1141 located between the two sets of locking members 1143. The remaining rollers 113 are respectively rolled sleeved on the transmission screw 1141 located in each set of locking members 1143. The circumferential surface of each roller 113 makes rolling contact with the carbon slide plate 2. The purpose is to reduce the resistance during movement when the device moves on the carbon slide plate 2 by rolling the rollers 113 on the carbon slide plate 2, thereby facilitating the movement of the device on the carbon slide plate 2.

[0069] Two knobs 1142 are respectively located at the two ends of the transmission screw 1141. The knobs 1142 are directly sleeved on the two ends of the transmission screw 1141, and each knob 1142 is located near the outer side wall of the guide rail seat 112. Each locking member 1143 has a bent part, which clamps the carbon slide plate.

[0070] The slide mechanism 12 is slidably sleeved on the guide rail mechanism 11 along the width direction; specifically, the guide rail 11 is provided with a guide rail 115 (specifically, the guide rail 115 is fixed to the upper surface of the guide rail 11 by screws), and the guide rail 115 extends along the width direction and matches the guide rail 11; the slide mechanism 12 includes: a sliding block 121, which is slidably sleeved on the guide rail 115 along the width direction.

[0071] The slide mechanism 12 and the guide rail mechanism 11 are jointly provided with a positioning mechanism for positioning the slide mechanism 11 after it slides on the guide rail mechanism 12. Specifically, the guide rail 115 has several positioning holes 116, which are opened along the width direction of the guide rail 115. The sliding block 121 has a corresponding insertion hole for the positioning hole 116. A pin 111 is inserted into the insertion hole and one of the positioning holes 116 to achieve positioning of the sliding block 121 after it slides on the guide rail 115. More specifically, the guide rail 115 has a first vertical surface 1151, on which several positioning holes 116 are opened, which are opened along the width direction of the guide rail 115 (ideally, the positioning holes 116 are on the first vertical surface 1151). (1. Equal spacing); the sliding block 121 has a second vertical surface 1221. The second vertical surface 1221, the first vertical surface 1151, and the vertical direction are all parallel. The second vertical surface 1221 has a corresponding insertion hole for the positioning hole 116. The insertion hole and one of the positioning holes 116 are inserted together to realize the positioning of the sliding block 121 after sliding on the guide rail 115. In addition, the sliding block 121 includes two matching sliding halves. The two sliding halves are fixedly installed along the length direction by screws, and a notch 122 matching the guide rail 115 is formed between the two sliding halves. The side wall part where the notch 122 is located wraps around the first vertical surface 1151 of the guide rail 115 to realize the stability of the sliding block 121 when sliding on the guide rail 115.

[0072] The movable structure 1 was adjusted as follows:

[0073] First, with the assistance of multiple rollers 113, the guide rail seat 112 on the moving structure 1 is manually moved on multiple carbon slide plates 2 until the indicator line 13 is aligned with the width direction on all the carbon slide plates 2.

[0074] Next, turn the knob 1142 to rotate the transmission screw 1141, thereby causing the two locking parts 1143 to move towards each other on the transmission screw 1141 with the assistance of two sets of reverse and forward threads, until they simultaneously clamp a carbon slide plate 2, thereby realizing the movement and positioning of the moving structure 1 in the length direction.

[0075] Finally, depending on the actual situation, the sliding block 121 is manually slid to slide on the guide rail 115 until it moves to the predetermined position. Then, the pin 111 is inserted into the insertion hole and the positioning hole 116 to position the sliding block 121 on one of the multiple carbon slide plates 2, thus realizing the movement and positioning of the moving structure 1 in the width direction.

[0076] This testing device shall be used in the following manner:

[0077] This detection device utilizes two moving structures 1 from Embodiment 1, thereby locking the two carbon slide plates 2 with locking members 1143 on the two moving structures 1 respectively. Both ends of each carbon slide plate 2 along the length direction are locked, so that the lower surface of this device achieves four pairs of locking members 1143 locking the two carbon slide plates 2. In addition to the carbon slide plates 2 not locked by the locking members 1143, the carbon slide plates 2 located on each guide rail seat 112 are also contacted by the rollers 113 located at other positions on the transmission screw 1141, thereby giving this device high stability. By moving and positioning the moving structure 1 in the length direction and in the width direction according to Embodiment 1, the stroke detection module and wear detection module in this device can detect the carbon slide plate 2 in the length direction or in the width direction to detect multiple carbon slide plates 2.

[0078] It should be noted that the walking mechanism, stroke detection module, wear detection module and touch screen in this embodiment are all derived from the patent authorized by our company on November 11, 2023, with the authorization announcement number CN220040124U, and will not be described in detail here.
