Description

Railway anti-slip fastener Technical Field The utility model relates to the technical field of vehicle anti-slip, in particular to a railway anti-slip fastener. Background The anti-slip fastener is an important tool for preventing a vehicle staying on a railway line from sliding, and the principle of the anti-slip fastener is that a hook of the fastener is used for hooking a brake chain of the vehicle, and a screw rod on the fastener is rotated by a spanner to enable the hook to tighten the brake chain, so that a brake shoe and a wheel tread are rubbed to generate a braking effect so as to prevent the vehicle from sliding. The existing invention patent with publication number CN112776850A discloses an intelligent fastener, a tension sensor arranged between a hook and a screw rod transmits the sensed tension to a microprocessor when in use, and the microprocessor further carries out subsequent indication, but when the existing tension sensor is sensitive, the tension sensor transmits a signal to the microprocessor when a vehicle passes by the side, so that false alarm is caused, and when the tension sensor is relatively slow, the signal cannot be fed back to the microprocessor accurately and timely, so that the vehicle cannot be found timely when sliding. Disclosure of Invention In order to solve the problem that the existing anti-slip fastener cannot be found in time when a vehicle slides when a tension sensor fails, the utility model provides the railway anti-slip fastener, a feedback mechanism of a magnet and a Hall element is additionally arranged on the basis of the tension sensor, when the vehicle slides, the magnet is pulled down from a magnetic suction block by a second connecting piece, and a signal is sent to a control module by the Hall element due to magnetic field change, so that the vehicle can be found to slide more accurately and timely. In order to achieve the above object, the technical scheme of the present utility model is as follows: The utility model provides a railway anti-slip fastener, includes couple, installed part, screw rod, first connecting piece and cardboard, the couple is hung and is established on the brake shoe chain of train, and the tip of couple is fixed on the installed part, the tip of screw rod is rotated with the installed part and is connected and be located one side that the couple was kept away from to the installed part, screw rod and first connecting piece threaded connection, be fixed with articulated seat on the first connecting piece, be fixed with tension sensor on the articulated seat, cardboard one end articulates on articulated seat, one side of cardboard is equipped with the magnetism and inhales the piece, has placed magnet on the magnetism and has been fixed with the second connecting piece on the magnet, and the one end that magnet was kept away from to the second connecting piece is fixed to ground, one side of cardboard still is equipped with hall element and control module, hall element's output and control module's input communication connection, tension sensor's output and control module's input communication connection. Further, the mounting piece comprises a first barrel and a second barrel, the axes of the first barrel and the second barrel are coincident, one end of the first barrel is fixedly connected with the hook, the second barrel is hollow, two ends of the second barrel are provided with openings, one end of the first barrel, which is far away from the hook, stretches into the second barrel and is in threaded connection with the second barrel, a ball bearing is arranged in the second barrel, and one end of the screw rod stretches into the second barrel and then penetrates through the ball bearing, and the end part of the screw rod is fixedly provided with a limiting piece. The fastener is installed in the vehicle downside, and its screw rod very easily takes place the position to interfere with the chassis of vehicle, and ball bearing in the installed part makes the screw rod can form certain slope when taking place the position to interfere with the chassis, and then guarantees the normal work of fastener. Further, a spring is arranged in the second cylinder, is positioned between the first cylinder and the ball bearing and is sleeved outside the screw rod. The spring enables the screw to remain relatively consistent with the axial direction of the mounting member without being subjected to external forces. Further, a clamping groove is formed in one end, close to the second cylinder, of the first cylinder, and one end of the spring extends into the clamping groove. The stability of the position of the spring in the second cylinder is ensured, and the probability of dislocation of the spring is reduced. Further, a shell is fixed on one side, far away from the hook part, of the clamping plate, and the Hall element and the control module are installed in the shell. Further, a slot is formed in the magnetic attraction block, and the magne
