[0061] In this embodiment, a specific implementation of a portable bridge assembly equipment is provided, wherein the middle part of the wire rope lifting device 2 is connected and fixed by a pin shaft 8, and the pin shaft 8 can rotate.

[0062] In one embodiment, the wire rope hoisting device 2 includes a hoisting device body 21, a wire rope guide wheel 22, and a hydraulic winch 23;

[0063] The lifting equipment body 21 is installed at the front end of the mobile carrier 1, and the bottom of the lifting equipment body 21 is fixedly connected to the multi-section deployment bridge 3;

[0068] In this embodiment, a specific implementation method is provided for installing the mobile vehicle 1 by pulling the mobile vehicle 1 with a cable 7. The cable 7 is two strands, and in order to ensure the overall balance of the vehicle body and stable installation, a cable 7 is used on each of the left and right sides for fixed installation.

[0069] In one embodiment, the multi-stage deployment bridge 3 is a short bridge 31 or a long bridge 32;

[0070] The short bridge 31 includes at least two sections of foldable bridge bodies;

[0071] The long bridge 32 includes at least four foldable bridge sections.

[0072] In the present embodiment, the multi-section deployable bridge 3 is a short bridge 31 with two sections, and a long bridge 32 with four sections. The sections are hingedly connected and can be deployed.

[0073] The bridge equipment is a manually assembled bridge, which can be lengthened and combined according to the load and length requirements, and is divided into a short bridge and a long bridge. The short bridge 31 includes an end rut 1.1, an end rut 2 1.2, an end middle cover plate 1.3 and a connecting beam 1.4, and the two sections are hingedly connected by a single-double-ear joint 1.1.1 and an upper bridge locking mechanism 1.1.2; the long bridge includes an end rut 1, an end rut 2, a middle rut, a middle middle cover plate and a connecting beam.

[0075] like Figure 1 and Figure 2 ,as well as Figure 4 As shown in the figure, different bridge lengths match different water widths, but the principle is the same. It should be pointed out here that when the wire rope is used to hoist a multi-section unfolded bridge, it cannot be folded further after it is in a horizontal state, so it can be formed. Figure 1 The triangular stable structure in the four-section structure is similar. In addition, the short bridge comprises a pair of end ruts 1, a pair of end ruts 2, 2 connecting beams and 4 end intermediate covers. The long bridge 32 also includes 4 end intermediate covers; in addition, it includes at least a pair of intermediate ruts, 3 connecting beams and 2 middle intermediate covers. The end ruts 1 and end ruts 2 on both sides, the end ruts 1 and the middle ruts, and the middle ruts and end ruts 2 are connected by the lower single-double ear joints and the upper bridge locking mechanism. The end ruts and the middle ruts of the short bridge and the long bridge are for equipment to pass. The end intermediate covers and the middle intermediate covers are thin plates for pedestrians to pass. The universal erection device is installed on the universal erection vehicle and can be connected to the universal erection vehicle by a wire rope to ensure stability during bridge erection. The bridge pick-up and the erection device structure are fixed by the upper connecting pin and the lower connecting pin. After the upper connecting pin is removed, the bridge pick-up can rotate along the lower connecting pin to put down the bridge equipment.

[0078] In one embodiment, the steel wire rope 4 is connected to the folded portion in the middle of the multi-section deployable bridge 3 .

[0079] In one embodiment, a slot structure 5 opened forward is provided at the bottom of the wire rope hoisting device 2, and a hinge structure 6 is provided above the slot structure 5. The hinge structure 6 includes an upper connecting pin 6.1 and a lower hinge pin 6.2, and the hinge structure 6 thus has two parts of hinge freedom, so that the hinge structure 6 and the slot structure 5 can each have a hinge freedom.

[0080] In one embodiment, the present invention further provides a method for laying a portable assembled bridge equipment, based on the portable assembled bridge equipment;

[0081] After unfolding the multi-section unfolding bridge and driving the mobile vehicle 1 forward, the unfolded multi-section unfolding bridge 3 is suspended above the pool 100;

[0082] Put down the multi-stage deployable bridge 3.

[0083] First, the bridge components are assembled into bridge equipment manually; then, the universal erection device is installed on the universal erection vehicle and fixed by fixed wire ropes and pins. Then, the erection wire rope on the universal erection device passes through the guide wheel and connects to the bridge equipment, and at the same time, the end of the bridge equipment is inserted into the structural groove of the universal erection device to fix the bridge equipment securely.

[0084] The hydraulic winch of the universal erection device retracts the erection wire rope to lift the bridge equipment, and then the universal erection vehicle carries the bridge equipment to the obstacle; the hydraulic winch of the universal erection device releases the wire rope to place one end of the bridge equipment on the ground, and then the upper connecting pin is removed, and the bridge equipment presses the bridge and rotates along the lower connecting pin, thereby completely lowering the bridge equipment to the ground.

[0085] The connection between the erection wire rope and the bridge equipment is released, and the universal erection vehicle withdrew with the universal erection equipment, and the bridge erection is completed.

[0086] The above embodiments are only exemplary embodiments of the present invention and are not intended to limit the present invention. The protection scope of the present invention is defined by the claims. Those skilled in the art may make various modifications or equivalent substitutions to the present invention within the essence and protection scope of the present invention, and such modifications or equivalent substitutions shall also be deemed to fall within the protection scope of the present invention.
