Detailed Description
The following further illustrates the specific structure of the present invention:
the structure of the bidirectional rail car is shown in figure 1, and the bidirectional rail car comprises a carriage 1, wherein the bottom of the carriage 1 is provided with a front moving wheel pair 2 and a rear moving wheel pair 3, each pair of moving wheels comprises two wheels, and the two wheels are respectively arranged on two sides of the lower part of the carriage 1 to form wheel pairs. The wheel shafts of the front moving wheel pair 2 and the rear moving wheel pair 3 are respectively connected with one end of a steering connecting shaft rod 4, the other ends of the two steering connecting shaft rods 4 are hinged with the two ends of a steering connecting rod 5, the middle position of the steering connecting rod 5 is hinged with one end of a swinging steering rod, a fixed shaft 7 is arranged in the middle of the swinging steering rod, the fixed shaft 7 is fixed at the bottom of the carriage 1, a vertically arranged guide rod 8 is arranged at the other end of the swinging steering rod, a guide wheel 9 is arranged at the lower end of the guide rod 8, the guide wheel 9 is arranged in a track, and the track limits the guide wheel 9 to enable the guide. The wheel shaft of the guide wheel 9 is vertically arranged, and the track is a track groove below the ground or a guide rail with an inner groove above the ground.
The swing steering rod connected with the front moving wheel pair 2 faces the front of the carriage, and the guide rod 8 at the front side of the front moving wheel pair 2 is positioned at the front of the carriage 1. The swinging steering rod connected with the rear moving wheel pair 3 faces the rear of the carriage. The guide bar 8 behind the rear moving wheel pair 3 is behind the carriage 1. The front and rear guide wheel sets ensure that the moving wheels and the carriage always move along the track direction.
The bottom of the carriage 1 is provided with a storage battery 10, and the wheels of the front moving wheel pair and the rear moving wheel pair are electric wheels with built-in motors. The rear of the carriage 1 is provided with a steering handle 11, the middle of the steering handle 11 is provided with a steering shaft 12, the steering shaft 12 is hinged on the rear side surface of the carriage 1, the lower end of the steering shaft 12 is provided with a swing rod 13, and the front end of the swing rod 13 is hinged in a steering groove on the swing steering rod.
The rear side of the carriage 1 is provided with a folding seat 14, and the folding seat 14 can be horizontally arranged or folded upwards. Pedals 15 protruding out of the rear side face of the carriage 1 are arranged on two sides of the folding seat 14 and close to the bottom of the carriage 1, a brake 16 is arranged on the pedal on one side, and the brake 16 controls the brake of the movable wheel pair.
The front side and the rear side of the carriage 1 are respectively provided with an anti-collision rod 17, a buffer spring 18 is arranged between the inner side of the square collision rod and the outer wall of the carriage 1, the buffer spring 18 is sleeved on a buffer rod 19, the length of the buffer rod 19 is shorter than that of the buffer spring 18, and the buffer rod 19 is fixed on the carriage 1.
The front and rear side surfaces of the carriage 1 are provided with cameras for monitoring and scanning the front and rear of the carriage 1. And anti-collision travel switches are arranged between the anti-collision rods and the wall of the carriage in the front and at the back of the carriage, when the buffer spring is compressed to a certain degree, the anti-collision rods touch the travel switches, and the motors inside the wheels, which are interconnected with the travel switches in a circuit, stop rotating, so that an anti-collision function is realized.
The guide rod 8 is hinged to the swing steering rod 6, the direction of the hinged shaft is horizontal, the middle position of the front side or the rear side edge of the lower side surface of the carriage 1 is provided with the fixed latch 20 with an inner groove, the guide rod 8 can be embedded into the inner groove to be fixed when rotating to the position of the fixed latch 20 to the lower side of the carriage 1 around the end part of the swing steering rod, the guide rod 8 and the guide wheel 9 are retracted from the track, and the carriage 1 can move on the common ground.
The downside of the swing steering rod behind carriage 1 still is equipped with removes kayser 21, removes kayser 21 and is provided with the inner groovy equally, removes kayser 21 and is in the outside of the fixed kayser 20 in carriage 1 rear, and the inner groovy lowest position of removing kayser 21 is less than fixed kayser 20, and when the guide bar 8 in carriage 1 rear rotated to the inner groovy of inlaying simultaneously removing kayser 21 and fixed kayser 20, the steering of back removal driving wheel pair 3 will be locked and can not turn to once more.
The working mode of the device is as follows:
the carriage of the device takes the direction without a handle as the advancing direction, the front guide wheel is simultaneously placed in the track with the guide groove, the rear guide rod is folded and embedded into the movable clamping lock and the fixed clamping lock, and the rear movable wheel pair is consistent with the length direction of the carriage. The motor in the wheel is started to drive the carriage to move. When the track is at a bending position, the front guide wheel deflects in the track bending direction, the guide rod drives the swinging steering rod to swing around the fixed shaft, the swinging steering rod drives the steering connecting rod and the steering connecting shaft rod to swing, the steering connecting shaft rod drives the wheel carrier of the wheel to rotate, and the rotating direction is consistent with the bending direction of the track. When the carriage runs in the opposite direction, the guide rods at the front and rear positions of the carriage are arranged in the opposite direction to the above content, and at the moment, the handlebar can correspondingly rotate along the track direction. In addition, the connecting position between the steering shaft and the swinging rod can be separated at the moment, and the function of the handlebar is invalid.
When the rail car reaches a warehouse or other destinations, the anti-collision rod collides with the limiting device at the destination position to trigger the emergency stop travel switch, so that the running stop is realized.
After unloading, the carriage runs reversely, at the moment, the guide wheel in the front guide rail is lifted and clamped in the parallel fixed clamping locks, and the forward moving wheel pair does not rotate relative to the carriage. The guide wheels connected to the rear pair of moving wheels are placed in the guide rails, in which case the guide bars are rotationally interconnected with the corresponding swing steering bar, steering connecting rod and steering connecting shaft.
The carriage moves under the driving of the moving wheel pair, the guide wheel in the rear direction runs along the track, the track running mode along the bending position is the same as that of the track running mode, and the switch touch is formed until the stopping position is reached to stop running.
The method is operated by a driver, and the functions on the common ground are realized as follows:
firstly, a guide rod in the direction of a front moving wheel pair of a carriage is rotated to be embedded into a fixed lock, a guide rod in the direction of a rear moving wheel pair is embedded into a moving lock, a steering guide shaft and a swing rod which are connected with a handlebar form linkage, and the swing rod is in linkage with a swing steering rod, a steering connecting rod and a steering connecting shaft rod. The handlebar is rotated, and the rotation of the rear moving wheel pair can be driven.
The bench 14 is opened, the handle is rotated to control the walking direction, and the use of the driver on the common ground is realized.
