Description

Crossing type rail grabbing device for railway Technical Field The utility model belongs to the technical field of rail transit, and particularly relates to a crossing type rail grabbing device for a railway. Background The car ladder is a common operation tool in railway contact net maintenance operation, and when the contact net maintenance operation is carried out, the car ladder in high-altitude operation needs to use an anti-toppling device, otherwise, the problem that the car ladder accidentally moves and even topples easily occurs. To prevent the car ladder from tipping over during operation, rail grippers are typically used to secure the car ladder. The existing rail grabbing device is complex in operation and easy to loosen, the operation time of the railway contact net is urgent, the time window is narrow, and the existing car ladder rail grabbing device is difficult to adapt to the requirement of contact net maintenance operation. Accordingly, there is a need to provide an improved solution to the above-mentioned deficiencies of the prior art. Disclosure of Invention The utility model aims to provide a crossing rail grabbing device for a railway, which aims to solve the problem that a railway working vehicle ladder is easy to loosen during working. In order to achieve the above object, the present utility model provides the following technical solutions: a cross rail grab for a railway, comprising: the beam is provided with 1 claw at each of two ends, and the proximal ends of the claws are rotationally connected with the beam; The end part of the cross beam is rotationally connected with a first connecting rod, the middle part of the first connecting rod is rotationally connected with the cross beam, one end of the first connecting rod, which is close to the clamping jaw, is provided with a second connecting rod, one end of the second connecting rod is rotationally connected with the middle part of the clamping jaw, and the other end of the second connecting rod is rotationally connected with one end, which is close to the clamping jaw, of the first connecting rod; the end of the beam is also provided with an elastic piece, the first end of the elastic piece is movably connected with the beam, and the second end of the elastic piece is movably connected with the connecting part of the clamping jaw and the second connecting rod. Preferably, the first end of the elastic element is closer to the middle part of the beam than the connection point of the clamping jaw and the beam. Preferably, jaw seats are arranged at two ends of the cross beam, the jaw seats are fixed relative to the cross beam, and the jaw and the first connecting rod are both rotationally connected with the jaw seats. Preferably, the clamping jaw and the clamping jaw seat are connected through a pin shaft. Preferably, an insulating sleeve is arranged on the pin shaft, and the pin shaft and the clamping jaw are separated by the insulating sleeve.
