4. The straddle type rail beam transporter according to claim 1, wherein the hoisting mechanism comprises a pole for supporting the rail beam, and the pole is connected to the cross beam by a steel wire.
5. The straddle-type rail beam transporter according to claim 4, wherein the pole is connected to the steel wire rope through a linkage mechanism, the linkage mechanism includes a hanging plate connected to the steel wire rope, the hanging plate passes The support frame is connected with the pole, and both ends of the support frame are hinged with the guide plate and the pole.
6. The straddle-type rail beam transporter according to claim 2, wherein the transporter further comprises a traversing trolley, the transporter includes at least two beams, and the two beams are spaced apart. The moving trolley is placed above the cross beam, and the steel wire rope is connected to the cross beam through the traverse trolley; the traverse trolley is connected with a traverse oil cylinder for driving the traverse trolley to move laterally; one end of the traverse oil cylinder is connected to the end beam, The other end is articulated with the traverse trolley.
7. The straddle-type rail beam conveyer according to claim 2, wherein the longitudinal beams are respectively connected to the driving mechanism or the braking mechanism through a rotary reducer.
8. The straddle-type rail beam transporter according to claim 2, wherein the longitudinal beam is connected to the braking mechanism through an equalization system; the equalization system includes a telescopic sleeve, and the longitudinal beam passes through the telescopic sleeve Connect with the brake mechanism.
9. The straddle-type rail beam transporter according to claim 8, wherein the telescopic sleeve comprises an outer sleeve connected to the longitudinal beam, and an inner sleeve is sleeved inside the outer sleeve, and the longitudinal beam passes through the telescopic sleeve. A rotary reducer is connected; the telescopic sleeve is connected to the brake wheel frame through a rotary reducer; a balancing oil cylinder is arranged in the telescopic sleeve; one end of the equalizing oil cylinder is connected with the inner wall of the outer jacket, and the other end is connected with the inner The inner wall of the sleeve is connected.
10. The method of using a straddle-type rail beam conveyor according to any one of claims 1-9, wherein the method of use includes the following steps:

    Step S101, take the beam; the two conveying machines travel empty to the beam taking pedestal at the tunnel entrance, install the hoisting mechanism and take the beam at a predetermined position on the pre-placed track beam;

    Step S102, transport the beam; the two transporters move in linkage to move the beam and move forward synchronously; the transporters independently control the steering to ensure that the transporter has a sufficient safe distance from the tunnel wall and the anchor box base;

    Step S103, drop the beam; the hoisting mechanisms of the two conveyors slowly drop the track beam, and finally the track beam is installed in place after mediation;

    In step S104, after the above steps are completed, the transport operation of the track beam is completed, and after the beam drop is completed, the two transporters each walk to the tunnel entrance and wait for the next rail beam to be lifted.
