Abstract

A translational contact rail power supply device includes a contact rail and a translation device. The translation device is arranged on one side of the running rail. The contact rail is fixed on the translation device and is parallel to the running rail. The contact rail is driven by the translation device to move parallelly closer to or farther away from the running rail. The present invention realizes the parallel movement of the contact rail relative to the running rail, meeting the power supply requirements of vehicles with different clearances. And when a special vehicle passes by, the contact rail can be moved outside the clearance of the vehicle, so that this section of the contact rail does not affect the normal passage of the special vehicle.

[0021] The present invention will be described in detail below with reference to the attached Figures 1-5 drawings and specific embodiments.

[0022] A translational contact rail power supply device includes a contact rail 1 and two sets of translation devices 2. The translation devices 2 are arranged on one side of the running rail 3. The contact rail 1 is fixed on the translation device 2 and is parallel to the running rail 3. The translation device 2 drives the contact rail 1 to move parallelly closer to or farther away from the running rail 3.

[0023] In one embodiment, the translation device 2 includes a driving mechanism 4, a base 5 and an insulating bracket 6. The driving mechanism 4 is arranged on the base 5, the insulating bracket 6 is arranged on the driving mechanism 4, and the contact rail 1 is fixed on the insulating bracket 6. The driving mechanism 4 drives the insulating bracket 6 to move closer to or farther away from the running rail 3.

[0024] In one embodiment, the driving mechanism 4 includes a motor 7, a lead screw 8, a lead screw nut 9 and a moving seat 10. The insulating bracket 6 is fixed to the upper end of the moving seat 10. The motor 7 is fixed to one end of the base 5 away from the running rail 3. A roller 11 is arranged below the moving seat 10, and the roller 11 is located on the base 5. The lead screw 8 is arranged perpendicular to the direction of the contact rail 1 and is connected to the motor 7. The lead screw nut 9 is sleeved on the lead screw 8 and is fixedly connected to the moving seat 10. The motor 7 drives the lead screw 8 to rotate to move the lead screw nut 9, and then drives the moving seat 10 to move along the base 5 through the roller 11.

[0025] In one embodiment, the base 5 is a guiding square tube, and the upper end of the guiding square tube has a strip-shaped opening perpendicular to the direction of the contact rail 1. The lower end of the moving seat 10 extends into the guiding square tube, and rollers 11 are installed on both sides of it, and the rollers 11 are located on both sides inside the guiding square tube. The lead screw 8 is arranged inside the guiding square tube, and one end of it is coaxially connected to the motor 7.

[0026] When power needs to be supplied to the vehicle running on the running rail 3, start the motors 7 to run synchronously. After moving the contact rail 1 parallelly to the working position, the motors 7 stop running. At this time, power can be supplied to the vehicle through the contact rail 1. Moreover, by controlling the running time of the motors, the contact rail 1 can be moved parallelly to different working positions to meet different clearance requirements. On the contrary, when power does not need to be supplied to the vehicle, start the motors 7 in reverse to move the contact rail 1 parallelly outside the clearance.

[0027] In order to limit the translation range of the contact rail 1, limit switches 14 are arranged at both ends inside the guiding square tube. When the moving seat 10 touches the limit switch 14, the motor 7 stops running.

[0028] In order to prevent the limit switches 14 from failing to limit, and the moving range of the contact rail 1 exceeds the set range, causing damage to personnel or other equipment. A baffle 15 is arranged inside the guiding square tube near the end of the running rail 3, and the baffle 15 is located outside the limit switch 14.

[0029] In order to ensure that the deflection of the contact rail 1 is within the allowable range, a support device 12 is provided between the translation devices 2. The support device 12 includes a guide seat 13, an insulating bracket 6, and a moving seat 10 arranged on one side of the running rail 3. A roller 11 is provided below the moving seat 10. The roller 11 is arranged on the guide seat 13. The insulating bracket 6 is fixed to the upper end of the moving seat 10, and the contact rail 1 is fixed to the insulating bracket 6. The guide seat 13 is a guide square tube, and the upper end of the guide square tube has a strip-shaped opening perpendicular to the direction of the contact rail 1. The lower end of the moving seat 10 extends into the guide square tube, and rollers 11 are installed on both sides thereof, and the rollers 11 are located on both sides inside the guide square tube.

[0030] The number of the support devices 12 provided is determined according to the length, cross-sectional shape and rigidity of the contact rail 1.

[0031] In order to prevent other external objects from falling into the guide square tube and ensure smooth operation of the rollers without jamming, a protective cover 16 following the moving seat 10 is provided above the guide square tube.

[0032] The above embodiments are only preferred embodiments of the present invention and are not used to limit the scope of implementation of the present invention. Therefore, all equivalent changes made according to the content described in the claims of the present invention should be included within the scope of the claims of the present invention.
