Detailed Description
The invention is further described below with reference to the accompanying drawings.
As shown in fig. 1, an automatic bidirectional locking mechanism for steel rails is used for rapidly grasping and lifting a steel rail to be laid, further locking the steel rail, then performing rail laying operation, and after pushing one steel rail, rapidly releasing the steel rail and then grasping the next steel rail. The device comprises a fixed seat 1 arranged on a track laying vehicle, a clamping assembly and an inclined propelling cylinder 7, wherein the clamping assembly comprises a main frame 2 and a gripping device arranged at the lower end of the main frame 2; the main frame 2 is arranged on the fixed seat 1 through a rotating part; the inclined propelling cylinder 7 is mounted on the fixing seat 1 and used for pushing the main frame 2 to rotate, when the grasping device grasps the steel rail 3, the grasped steel rail is lifted, then the inclined propelling cylinder 7 is used for rotating the main frame 2, so that the main frame inclines along the length direction of the steel rail, the grasped steel rail 3 can be further locked, the main frame 2 returns, and the locked steel rail 3 can be released.
The main frame is pushed to incline to enable the grasping device to lock the steel rail, because the grasping device only hangs the rail head of the steel rail when grasping the steel rail and can only lift the steel rail, but not completely grasp the steel rail, and the stress requirement of pushing the steel rail cannot be met. The principle that the grasping device locks the steel rail by pushing the main frame to incline is that the longitudinal force of the pushing steel rail 3 is converted into the fastening force of the grasping device to the steel rail by changing the stress angle between a stress component in the grasping device and the steel rail so as to meet the stress requirement of the pushing steel rail.
The inclined propelling cylinder 7 can be an air cylinder or an electromagnetic cylinder, and preferably, an oil cylinder is selected and used in the invention.
Through the setting, can realize snatching the rail fast and further lock through promoting the body frame forward or backward slope with the rail that snatchs rapidly, whole mechanism can form a rigidity whole temporarily, can be along with applying the instant vertical power of rail conduction of the direction of traction force on the fixing base 1, realize the propelling movement to the rail, simultaneously, again can relieve the locking restraint fast when necessary and release the rail completely.
The actions and effects of the further improvement of the present invention will be described below.
As shown in fig. 2, the main frame 2 includes a main frame end plate 21, and a first mounting plate 22 and a second mounting plate 23 symmetrically fixed on the lower end surface of the main frame end plate 21, and a space is formed between the first mounting plate 22 and the second mounting plate 23 to form a mounting space of the main frame. The main frame 2 is a mounting frame for all clamping assemblies, and the arrangement is mainly used for providing mounting positions for further arrangement of other components in the clamping assemblies.
As shown in fig. 2, 3 and 4, the gripping device comprises a first hanging pin 13 and a second hanging pin 14, the first hanging pin 13 and the second hanging pin 14 are respectively positioned in a first hanging pin hole 223 and a second hanging pin hole 233 which are symmetrically arranged at the lower ends of a first mounting plate 22 and a second mounting plate 23, and the first hanging pin 13 and the second hanging pin 14 can be respectively inserted into and pulled out of the first hanging pin hole 223 and the second hanging pin hole 233. In a preferred embodiment of the present invention, when the grasping means grasps the rail, the rail head is grasped by extending the first and second hooks 13 and 14 from both sides of the rail to the lower bottom surfaces of both sides of the rail head, and the rail can be first lifted up and then further grasped.
As shown in fig. 1-6, the gripping device further comprises a front tread surface 221 and a rear tread surface 222 which are respectively formed by the lower end surface of the mounting plate one 22, and a front tread surface two 231 and a rear tread surface two 232 which are respectively formed by the lower end surface of the mounting plate two 23; when the rail is gripped, the first hanging pin 13 and the second hanging pin 14 are respectively inserted into the first bottom surface 31 and the second bottom surface 32 at two sides of the rail head of the rail 3 from the first hanging pin hole 223 and the second hanging pin hole 233, and the first front tread 221 and the first rear tread 222 of the first mounting plate 22 and the second front tread 231 and the second rear tread 232 of the second mounting plate 23 are respectively positioned above the first top surface 33 and the second top surface 34 of the rail bottom at two sides of the rail 3; when the lower end of the main frame 2 inclines forwards after the rail is gripped, the first hanging pin 13 and the second hanging pin 14 respectively contact with the bottom surfaces on two sides of the rail head to be stressed, the first rear stepping surface 222 and the second rear stepping surface 232 respectively contact with the first top surface 33 and the second top surface 34 on two sides of the rail head to be stressed, and the rail is locked in a forward inclining mode (see fig. 5). The greater the longitudinal force applied to the frame 2, the greater the forces applied to the first and second suspension pins 13 and 14 and to the first and second rear treads 222 and 232. The steel rail is locked, and the vertical force is converted into positive pressure applied to two side surfaces of the rail bottom and two side bottom surfaces of the rail head after the main frame 2 is inclined and amplified, so that the first hanging pin 13, the first rear tread 222, the second hanging pin 14 and the second rear tread 232 are clamped between the bottom surface of the rail head and the top surface of the rail bottom. When the lower end of the main frame 2 tilts backwards after the rail is gripped, the first hanging pin 13 and the second hanging pin 14 respectively contact with the first bottom surface 31 and the second bottom surface 32 on two sides of the rail head to bear force, the first front tread 221 and the second front tread 231 respectively contact with the first top surface 33 and the second top surface 34 on two sides of the rail bottom to bear force, and the rail is locked in a backward tilting mode (see fig. 6).
The inclination of the lower end of the main frame 2 is performed by the thrust applied from the inclination cylinder 7 to the lower portion of the main frame 2. When the thrust applied by the inclined propelling cylinder 7 maintains the current situation, the whole automatic bidirectional locking mechanism of the steel rail temporarily forms a rigid whole, namely a specific fixed posture can be temporarily kept, so that the traction force applied to the main frame 2 is instantly transmitted to the locked steel rail, and the pushing of the steel rail can be realized.
