[0017] Example: Figures 1 to 7 As shown, the highway gantry rail vehicle in this embodiment includes the following structure: like Figure 1 As shown, the main body in this embodiment includes a gantry 1, a rail car 2, a first vertical lifting system 3, and a second vertical lifting system 4. The first vertical lifting system 3 and the second vertical lifting system 4 have the same structure, and both include a winch 31, a cable 32, a pulley block 33, and a hanger 34.
[0018] During vertical operation, the rail vehicle 2 is operated vertically by the first vertical lifting system 3 and the second vertical lifting system 4. Figure 1 Taking the first vertical lifting system 3 on the right side as an example, by pressing the start / stop button 51 of the control terminal 5, the rail vehicle 2 starts, and the hoist 31 in a set of vertical lifting systems is powered on. By pressing the up and forward buttons 52 of the control terminal 5, the hoist 31 rotates to cause the cable 32 to contract, and the rail vehicle 2 rises; by pressing the down and backward buttons 53 on the control terminal 5, the hoist 31 rotates to cause the cable 32 to lengthen, and the rail vehicle 2 descends; by pressing the brake button 54 on the control terminal 5, the hoist 31 brakes, and the rail vehicle 2 slows down until it stops.
[0019] like Figure 2 As shown, when the rail vehicle 2 rises to the point where the first guide sleeve 24 is separated from the vertical track set on the side 11 of the gantry 1, the rail vehicle 2 automatically brakes until it runs to the top position of the gantry 1, triggering the bottom support 13 to rotate outward until it is horizontal, and the bottom support 13 and the top surface 12 form a whole, allowing the rail vehicle 2 to run horizontally. In this embodiment, the bottom support 13 is composed of a rotating shaft 131, a support plate 132, and a limit block 133, wherein the support plate 132 is connected to the gantry 1 through the rotating shaft 131, and the limit block 133 is set at the outer position of the support plate 132, and the limit block 133 limits the rail vehicle 2 from running outward (or sliding) to prevent it from falling. Press the rising and forward buttons 52 on the control terminal 5, the wheels 23 rotate, and the rail vehicle 2 moves forward; press the descending and backward buttons 53, the wheels 23 rotate, and the rail vehicle 2 moves backward; press the brake button 54, the wheels 23 brake, and the rail vehicle 2 slows down until it stops running.
[0020] Combination Figure 3 and Figure 4 As shown, the main body of the rail vehicle 2 includes a vehicle box 21 and a base 22. The base 22 further includes a base shell 221, a first electromagnet 222, a pin 223, a stopper 224, a spring 225, an electromagnet pair 226, and a connecting plate 227.
[0021] The rail vehicle 2 is connected to the vertical lifting system through the base 22, and the first electromagnet 222, the pin 223, and the limit plate 224 are installed on the base shell 221. When the rail vehicle 2 is ready to be lifted, the hanging piece 34 of the vertical lifting system drops to the inside of the base 22, the first electromagnet 222 and the second electromagnet 342 on the hanging piece 34 are energized at the same time, the corresponding positions attract each other, the hanging piece 34 is accurately combined with the base 22, the limit plate 224 is triggered to open, the pin 223 enters the inside of the hanging piece 34 through the base shell 221, and the hanging piece 34 is firmly connected to the base 22. When the lifting of the rail vehicle is completed and the unhooking signal is received, the electromagnet pair 226 is energized and attracts each other, the spring 225 is compressed, and the connecting plate 227 is driven to retreat, the pin 223 leaves the hanging piece slot 343 and the base shell 221, triggering the limit plate 224 to reset (close), and the hanging piece 34 is separated from the base 22.
[0022] like Figure 5 As shown, a guide sleeve 24 and a guide sleeve 25 are provided on the side of the car body 21. The guide sleeve 24 includes a guide tube 241, a connecting rod 242, and a contact sensor 243; the guide sleeve 25 includes a guide tube 241 and a connecting rod 242. One end of the connecting rod 242 is connected to the outer wall of the car body 21, and the other end is connected to the guide tube 241 to fix the guide tube 241 on the car body 21. The guide sleeve 241 cooperates with the vertical track on the side 11 of the gantry 1 to achieve the limit when the rail car 2 is lifted or lowered. The contact sensor 243 is used to sense the time point when the guide sleeve 24 located above is separated from the vertical track. Let it be t0. The vertical lifting system braking is triggered at t0+△t. Let the initial velocity be v0 and the acceleration be a. Then the stroke length from t0 to the completion of the braking of the rail car (stationary) is: S=△t*v0+v0*v0 / 2a; The characteristic of setting the height of the contact sensor 243 is that the vertical distance h between the contact sensor 243 and the bottom surface of the wheel 23 is equal to S, so as to realize automatic braking of the rail vehicle 2 and keep it stationary at the height of the top surface 12 of the gantry 1.
[0023] like Figure 6 As shown, the hanger 34 on the first vertical lifting system 3 and the second vertical lifting system 4 includes a hanger base 341, a second electromagnet 342, and a hanger slot 343. Among them, the second electromagnet 342 is installed on the hanger base 341, and the side of the hanger base 341 is hollowed out to form a hanger slot 343. The second electromagnet 342 and the first electromagnet 222 are both composed of three groups of electromagnets, and the centers of the three groups of electromagnets form an equilateral triangle and determine a unique plane. The maximum required rotation angle for the first electromagnet 222 and the second electromagnet 342 to attract each other is only 60°, which is convenient for the connection between the hanger 34 and the base 22.
[0024] like Figure 7As shown, the control terminal 5 includes a start / stop button 51, an up and forward button 52, a down and backward button 53, a brake button 54, and a display screen 55; the control terminal 5 displays the connection status between the hanger 34 and the base 22, and controls the operation of the rail vehicle 2.
[0025] When applied, this embodiment includes the following control method: Start the first vertical lifting system 3 or the second vertical lifting system 4 located on the outside to make the rail vehicle 2 rise along the vertical track on the side of the gantry 1; The bottom support 13 rotates outward until it is horizontal, and the support plate 132 of the bottom support 13 forms an integral body with the top surface 12 of the gantry 1, and the rail vehicle 2 runs on the top surface 12 of the gantry 1, so that the rail vehicle 2 completes the running from the outside of the highway to the middle lane position; The rail vehicle 2 moves along the top surface of the gantry 1 to the middle lane position, and the corresponding second vertical lifting system 4 or the first vertical lifting system 3 makes the rail vehicle 2 descend along the vertical track of the side surface 1 of the gantry.
