Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
The embodiment of the present invention will be described with the vertical direction in fig. 2 and the horizontal direction in the horizontal direction. As shown in fig. 1-2, a semi-automatic high-speed rail board stripper comprises a frame 5, a running rail 16, a hydraulic push rod 3 and a grabbing mechanism, wherein the bottom of the frame 5 is rotatably connected with wheels 10, the wheels 10 are fixedly connected with transmission shafts 9 respectively, the transmission shafts 9 are connected with a driving motor 7, and the frame 5 is driven by the driving motor 7 to horizontally and longitudinally move on the running rail 16; the lower part of the frame 5 is hinged with a lifting frame 1 through a pin shaft 8, and four corners of the lower part of the lifting frame 1 are fixedly connected with hydraulic cylinders 12 extending downwards.
Be equipped with horizontal straight line track 2 on lifting frame 1, straight line track 2 is two, and sliding connection has in every straight line track 2 and snatchs support 19, and every both ends that snatch support 19 are fixedly connected with respectively and have grabbed the mechanism, snatch the mechanism and include electric jar 6 and connect the hoist 13 in electric jar 6 bottom, and hydraulic push rod 3's flexible end is connected with snatching support 19, and the stiff end is connected with lifting frame 1. The grabbing mechanism horizontally and transversely moves on the linear track 2 through the extension and retraction of the hydraulic push rod 3.
The semi-automatic high-speed rail track board stripper further comprises a controller, wherein a gravity sensor 11 is arranged at the joint of the electric cylinder 6 and the lifting appliance 13, and the input end of the controller is electrically connected with the gravity sensor 11. A positioning sensor is fixedly connected to the running track 16, and the grating displacement sensor 15 can be used as the positioning sensor. The positioning sensor is electrically connected with the input end of the controller, and the driving motor 7 and the hydraulic cylinder 12 are respectively electrically connected with the output end of the controller.
The working process of the utility model is as follows:
the driving motor drives the transmission shaft to rotate, and the transmission shaft drives the wheels to run on the running track. The displacement distance and the critical support reaction force are preset on the controller, the grating displacement sensor transmits the displacement distance to the controller in real time, and when the displacement distance reaches the preset position, the controller stops driving the motor to run. The pressure sensor transmits real-time pressure to the controller, and the controller stops the hydraulic cylinder from extending when the hydraulic cylinder is started to extend downwards to be in contact with the track slab steel die and generate preset support reaction force. At the moment, the electric cylinder is started to enable the lifting appliance to move downwards, the electric cylinder is retracted upwards after the lifting appliance descends to grab the lifting lugs of the track slab, and the lifting appliance drives the track slab to lift upwards. Because of the supporting reaction effect of the hydraulic cylinder, the track slab steel mould and the steel mould transport vehicle cannot be driven to lift together, and the track slab can be easily separated from the track slab steel mould.
