Description

Technical Field

[0001] The utility model relates to the technical field of track power taking, and more specifically to a track power taking device for an electric flat car. Background Art

[0002] The cross - span electric flat car in the workshop adopts a track low - voltage power supply method, that is, the low - voltage power provided by the track is supplied to the cross - span flat car motor through a power taking device, so as to realize the stable operation of the cross - span electric flat car on the track.

[0003] The original power taking device of the existing cross - span electric flat car consists of a cast iron block, a wire and a compression spring mechanism. Among them, the cast iron block is in close contact with the track through the compression spring mechanism, and the wire connects the low - voltage power taken from the track to the motor of the cross - span electric flat car through the wire to realize the power taking process.

[0004] However, the contact between the cast iron block and the track is surface - to - surface contact with a large contact area. This structure causes very loud noise between the cast iron block and the track during the operation of the cross - span electric flat car, which has a greater harm to the physical and mental health of on - site operators and does not meet the industrial enterprise boundary environmental noise emission standard. Content of the Utility Model

[0005] In order to overcome the above - mentioned defects of the prior art, the utility model provides a track power taking device for an electric flat car. By providing a pressing force through a pressing spring, the brass conductive block is in close contact with the outer circular surface of the wheel. The brass conductive block conveys the low - voltage power on the track to the vehicle body through a wire and a terminal, thereby realizing the power taking process. And because the contact between the brass conductive block and the outer circular surface of the wheel is line contact with a small contact area, the utility model generates almost no noise during operation, eliminating the physical and mental harm caused by noise pollution to on - site workers, so as to solve the problems appearing in the above - mentioned background art.

[0006] To achieve the above object, the utility model provides the following technical solution: A track power taking device for an electric flat car, including a wheel assembly installed on the vehicle body;

[0007] A plurality of power taking assemblies for track power taking are arranged outside the wheel assembly;

[0008] Each power taking assembly includes a nylon insulating sleeve. Inside one end of the nylon insulating sleeve close to the wheel assembly, there is a brass conductive block, and a pressing spring is installed on one side of the brass conductive block close to the nylon insulating sleeve. One end of the pressing spring far from the brass conductive block is fixed to the inner wall of the nylon insulating sleeve;

[0009] A wire for connecting a brass conductive block is disposed inside the compression spring. One end of the wire away from the brass conductive block penetrates through the nylon insulating sleeve and extends to the outside of the nylon insulating sleeve, and a terminal is installed at the end of the wire away from the nylon insulating sleeve.

[0010] In a preferred embodiment, the wheel assembly includes two drive shafts, two wheels mounted on the drive shafts, a control electric box, a transmission device, and a plurality of bearing seats. The control electric box and the transmission device are both installed at the bottom of the vehicle body. The plurality of bearing seats are respectively sleeved outside the two drive shafts, and the bearing seats are installed at the bottom of the vehicle body. One end of the brass conductive block away from the nylon insulating sleeve is in contact with the wheel. Through the arrangement of the wheel, the drive shaft, the bearing seat, and the control electric box, the movement of the vehicle body can be ensured.

[0011] In a preferred embodiment, an insulating frame is sleeved outside one end of the brass conductive block away from the nylon insulating sleeve, and a protective frame is sleeved outside the insulating frame. The protective frame is sleeved outside the nylon insulating sleeve, and the brass conductive block is located inside the protective frame. Through the connection between the insulating frame and the brass conductive block, the protective frame can move in unison with the brass conductive block by means of the insulating frame, ensuring the protective effect of the protective frame on the brass conductive block, avoiding damage to the brass conductive block caused by external collisions and other factors, and ensuring the service performance of the brass conductive block.

[0012] In a preferred embodiment, the length of the protective frame is less than the length of the brass conductive block. By setting the length of the protective frame to be less than the length of the brass conductive block, while the protective frame protects the brass conductive block, it does not prevent the movement of the brass conductive block.

[0013] In a preferred embodiment, a mounting steel plate is sleeved outside one end of the nylon insulating sleeve away from the wheel for connecting to the vehicle body. By connecting the mounting steel plate to the vehicle body, the power-taking assembly can be kept in motion consistency with the vehicle body, enabling the brass conductive block to always be in contact with the wheel for power-taking operation.

[0014] In a preferred embodiment, a fixed channel steel is installed on one side of the vehicle body bottom corresponding to the mounting steel plate. The mounting steel plate is fixed to the fixed channel steel by bolts. Through the connection between the fixed channel steel and the mounting steel plate, the nylon insulating sleeve can be installed and fixed, thereby ensuring the stability of the power-taking assembly.

[0015] The technical effects and advantages of the present utility model:

[0016] 1. A pressing force is provided by a compression spring, enabling the brass conductive block to be in close contact with the outer circular surface of the wheel. The brass conductive block transmits the low-voltage electricity on the track to the vehicle body through wires and terminal blocks, thereby realizing the power-taking process. Moreover, since the brass conductive block is in line contact with the outer circular surface of the wheel and the contact area is small, almost no noise is generated during the operation of the present invention, eliminating the physical and mental harm caused by noise pollution to on-site workers.

[0017] 2. Through the connection between the insulating frame and the brass conductive block, the protective frame can move in unison with the brass conductive block by means of the insulating frame, ensuring the protective effect of the protective frame on the brass conductive block, avoiding damage to the brass conductive block caused by external collisions and other factors, and ensuring the service performance of the brass conductive block.

Detailed Description of the Invention

[0024] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0025] Referring to the attached Figures 1-5 drawings, the present invention provides a track power-taking device for an electric floor trolley, including a wheel assembly installed on the vehicle body 1;

[0026] As Figures 1-3As shown in the figure, the wheel assembly includes two drive shafts 8, two wheels 9 mounted on the drive shafts 8, a control electric box 10, a transmission device 11, and multiple bearing seats 12. The control electric box 10 and the transmission device 11 are both mounted on the bottom of the vehicle body 1. The multiple bearing seats 12 are respectively sleeved outside the two drive shafts 8, and the bearing seats 12 are mounted on the bottom of the vehicle body 1. One end of the brass conductive block 4 away from the nylon insulating sleeve 3 is in contact with the wheel 9. Through the arrangement of the wheel 9, the drive shaft 8, the drive shaft 8, the bearing seat 12, and the control electric box 10, the movement of the vehicle body 1 can be ensured.

[0027] In order to reduce noise during power taking, multiple sets of power taking components for taking power from the track 2 are provided outside the wheel assembly;

[0028] As Figures 2-5 shown in the figure, each set of power taking components includes a nylon insulating sleeve 3. Inside one end of the nylon insulating sleeve 3 close to the wheel assembly, there is a brass conductive block 4. On one side of the brass conductive block 4 close to the nylon insulating sleeve 3, there is a compression spring 5 mounted, and one end of the compression spring 5 away from the brass conductive block 4 is fixed to the inner wall of the nylon insulating sleeve 3. Inside the compression spring 5, there is a wire 6 for connecting the brass conductive block 4. One end of the wire 6 away from the brass conductive block 4 penetrates through the nylon insulating sleeve 3 and extends outside the nylon insulating sleeve 3, and a terminal 7 is mounted at the end of the wire 6 away from the nylon insulating sleeve 3.

[0029] As Figure 4 shown in the figure, outside one end of the brass conductive block 4 away from the nylon insulating sleeve 3, there is an insulating frame 13 sleeved, and outside the insulating frame 13, there is a protective frame 14 sleeved. The protective frame 14 is sleeved outside the nylon insulating sleeve 3, and the brass conductive block 4 is located inside the protective frame 14. Through the connection between the insulating frame 13 and the brass conductive block 4, the protective frame 14 can move in unison with the brass conductive block 4 by means of the insulating frame 13, ensuring the protective effect of the protective frame 14 on the brass conductive block 4, avoiding damage to the brass conductive block 4 caused by external collisions and other factors, and ensuring the service performance of the brass conductive block 4.

[0030] As Figure 4 shown in the figure, the length of the protective frame 14 is less than the length of the brass conductive block 4. By setting the length of the protective frame 14 to be less than the length of the brass conductive block 4, while the protective frame 14 protects the brass conductive block 4, it does not interfere with the movement of the brass conductive block 4.

[0031] As Figure 2 and 3As shown, an installation steel plate 15 is sleeved outside one end of the nylon insulating sleeve 3 far away from the wheel 9 for connecting to the vehicle body 1. By connecting through the installation steel plate 15 and the vehicle body 1, the power-taking component can be kept in motion consistency with the vehicle body 1, enabling the brass conductive block 4 to always be in contact with the wheel 9 for power-taking operation. On one side of the vehicle body 1 bottom corresponding to the installation steel plate 15, a fixed channel steel 16 is installed. The installation steel plate 15 is fixed to the fixed channel steel 16 through bolts. Through the connection between the fixed channel steel 16 and the installation steel plate 15, the nylon insulating sleeve 3 can be installed and fixed, thereby ensuring the stability of the power-taking component.

[0032] First, the staff installs the power-taking component to the bottom of the vehicle body 1 through the connection between the installation steel plate 15 and the fixed channel steel 16, and makes the brass conductive block 4 in the nylon insulating sleeve 3 contact with the outer circular surface of the wheel 9. At the same time, with the pressing force provided by the pressing spring 5, the brass conductive block 4 is in close contact with the outer circular surface of the wheel 9. The brass conductive block 4 transmits the low-voltage electricity on the track 2 to the vehicle body 1 through the wire 6 and the wiring terminal 7, thereby realizing the power-taking process. And because the brass conductive block 4 and the outer circular surface of the wheel 9 are in line contact with a small contact area, almost no noise is generated during the operation of the present invention, eliminating the physical and mental harm caused by noise pollution to the on-site staff.

[0033] Finally: The above are only the preferred embodiments of the present invention and are not used to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
