Description

TECHNICAL FIELD

[0001] The utility model relates to rail transit maintenance technical field, concretely is a rail transit maintenance operation platform flap magnetic attraction device. BACKGROUND

[0002] There is a maintenance operation platform in the motor train maintenance base, which mainly functions to facilitate the motor train maintenance personnel to get on the roof or enter the motor train to carry out daily maintenance.

[0003] In order to ensure the normal operation of the motor train, a certain gap must be left between the two sides of the motor train and the maintenance operation platform; in order to enable the operating personnel to get on the roof, a flap mechanism is installed between the roof of the motor train and the maintenance operation platform to make up for the gap between the motor train and the maintenance operation platform. When the operating personnel need to get on the roof, the flap mechanism is laid flat to facilitate the operating personnel to get on the roof; when the motor train needs to run, the flap is vertically retracted to facilitate the passage of the motor train.

[0004] The full length of the maintenance operation platform of each line is 432 meters, and the flap mechanism is evenly distributed on both sides of the motor train line, including platform side flaps and net side flaps. The size of the platform side flap is 4500*500mm, and 96 flaps are provided for each line; the size of the net side flap is 9000*400mm, and 48 flaps are provided for each line; these flaps are driven by air cylinders to turn over according to the design requirements.

[0005] In the motor train maintenance warehouse, when the motor train needs to run, the flaps between the motor train and the maintenance operation platform must be vertically retracted to facilitate the passage of the vehicle; if the flaps are not retracted or are retracted and then uncontrollably turned over during the running of the vehicle, the running vehicle will rub against or collide with the flaps, causing damage to the vehicle or the platform. Therefore, during the running of the vehicle in and out of the warehouse, the flap mechanism must be ensured to be vertically retracted.

[0006] The turning over of the flap mechanism is driven by a double-acting cylinder, and when the flap is turned over to the set angle, the lock pin of the cylinder automatically locks the working position of the cylinder. However, due to long-term use, the lock pin, sealing element and other parts are worn out, the cylinder locking is unstable, and even the flap automatically turns over to the flat condition in the vertical position, which is absolutely not allowed.

[0007] If the flaps are not retracted or are retracted and then uncontrollably turned over to the flat condition during the running of the vehicle, the running vehicle will rub against or collide with the flaps, causing damage to the vehicle or the platform. Although this phenomenon of uncontrollable downward turning over of the flaps rarely occurs, once it occurs, it will cause irreparable damage to the vehicle or the maintenance operation platform.

Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the protection scope of the utility model.

[0023] Please refer to Figures 1-3 The application provides a rail transit maintenance operation platform flap magnetic attraction device, which is installed on a guardrail upright column 1 of a maintenance operation platform and is used for adsorbing a flap body 2 (the flap body 2 includes a platform side flap (see Figures 1-2 ) and a net side flap (see Figure 3The adsorption of the anti-collision strong neodymium magnet 4 includes locking the clamping hoop 3, which is fastened on the guardrail stand 1 of the maintenance platform by threads, for fixing the whole device; the anti-collision strong neodymium magnet 4 is arranged on one side of the clamping hoop 3 corresponding to the flap body 2 and is fixed on the clamping hoop 3 by means of the countersunk screw 5, the connection of the countersunk screw 5 avoids the connection protrusion and affects the adsorption effect, the magnet adsorption plate 6 is arranged on the upper surface of the flap body 2 corresponding to the anti-collision strong neodymium magnet 4, which is convenient for the adsorption of the anti-collision strong neodymium magnet 4, and the size of the magnet adsorption plate 6 is matched with that of the anti-collision strong neodymium magnet 4; when the flap body 2 is driven to flip to the vertical state by the external driving structure, the anti-collision strong neodymium magnet 4 can be adsorbed on the magnet adsorption plate 6, thereby preventing the flap from flipping down when the cylinder lock pin fails, and ensuring the safety of vehicle passing.

[0024] Further, see Figure 2 In order to improve the stability and adjustability of the device, the magnet mounting bracket 7 is arranged between the anti-collision strong neodymium magnet 4 and the locking clamping hoop 3, the connecting piece 8 is arranged on the clamping hoop 3 corresponding to the magnet mounting bracket 7, the magnet mounting bracket 7 is fixed on the connecting piece 8 by means of bolts, and the anti-collision strong neodymium magnet 4 is fixed on the other end of the magnet mounting bracket 7 by means of the countersunk screw 5; this design not only enhances the fixing strength of the magnet, but also provides additional support through the magnet mounting bracket 7 to ensure that the magnet remains stable during adsorption.

[0025] Meanwhile, two connecting holes 9 for bolt fixing connection are respectively arranged corresponding to the connection between the connecting piece 8 and the magnet mounting bracket 7, one of the connecting holes 9 is an arc-shaped hole 10 for rotating the magnet mounting bracket 7 by a proper angle, and this arc-shaped hole 10 design allows the magnet mounting bracket 7 and the anti-collision strong neodymium magnet 4 to rotate together by a proper angle around the shaft, thereby avoiding the impact vibration between the anti-collision strong neodymium magnet 4 and the flap body 2 when the flap body 2 is flipped up, and the anti-collision strong neodymium magnet 4 cannot be well adsorbed; this design significantly reduces the problem of poor adsorption caused by vibration, and improves the reliability and service life of the device.

[0026] The specific size of the anti-collision strong neodymium magnet 4 is 60mm in diameter and 15mm in thickness, and such size of the magnet can ensure sufficient adsorption force while avoiding affecting the overall layout of the device due to excessive volume.
