[0048] Two sets of transverse trolleys 2 are also provided, which are respectively located at the bottom positions of both ends of the length of the frame 6 and located on the inner side of the longitudinal trolley 1.

[0049] The hydraulic mechanism 3 is used to realize the movement and steering of the longitudinal trolley 1 and the transverse trolley 2 .

[0050] The electrical control mechanism 5 is used to control the operation of the longitudinal trolley 1 and the transverse trolley 2, the safety detection of the surrounding environment, and the reception of upper-level instructions to perform the tasks of the four-way transport vehicle for rails of the present invention.

[0051] The battery energy mechanism 4 provides a power source for the longitudinal trolley 1 , the transverse trolley 2 , the hydraulic mechanism 3 , and the electrical control mechanism 5 .

[0052] Combination Figure 4 As shown, the longitudinal trolley 1 includes a longitudinal trolley frame 105 , longitudinal driving wheels 104 , a longitudinal driving transmission mechanism and a vertical guiding device 106 .

[0053] The longitudinal trolley frame is connected to the frame 6 through a vertical guide device.

[0054] There are four longitudinal driving wheels 104 , which are respectively installed at the four corners of the longitudinal trolley frame 105 , and are symmetrically located at the bottom positions of both ends of the frame 6 in pairs.

[0055] There are two sets of longitudinal drive transmission mechanisms, which respectively drive two corresponding longitudinal drive wheels 104 .

[0056] The fixed end of the vertical guide device 106 is connected and fixed to the longitudinal trolley frame 105, and the movable end (guide rod) is connected and fixed to the frame 6. The fixed end can move vertically up and down along the guide rod.

[0057] The longitudinal drive transmission mechanism includes a longitudinal drive motor 101 , a reducer 102 and a transmission shaft 103 .

[0058] The output side of the longitudinal drive motor 101 is connected to the input side of the speed reducer 102 .

[0060] The longitudinal driving motor 101 drives the longitudinal driving wheel 104 through the reducer 102 and the transmission shaft 103 to realize the longitudinal movement of the rail four-directional transport vehicle of the present invention.

[0061] Combination Figure 5 As shown, the transverse trolley 2 includes a transverse trolley frame 204, a transverse driving wheel 203 and a transverse driving transmission mechanism.

[0062] The transverse trolley frame 204 is rigidly fixed to the frame 6 by bolts.

[0064] There are two sets of transverse drive transmission mechanisms, which drive two corresponding transverse drive wheels 203 respectively.

[0065] The transverse drive transmission mechanism includes a transverse and longitudinal drive motor 201 and a reducer 202 .

[0069] The longitudinal drive transmission mechanism and the transverse drive transmission mechanism can realize the four-way rail transport vehicle of the present invention to run on the longitudinal track and the transverse track respectively, and realize the rapid reversal of the four-way rail transport vehicle of the present invention. When the four-way rail transport vehicle of the present invention runs on the longitudinal track, the longitudinal trolley 1 works, the transverse trolley 2 is lifted and separated from the transverse track; when the four-way rail transport vehicle of the present invention runs on the transverse track, the transverse trolley 2 works, the longitudinal trolley 1 is lifted and separated from the longitudinal track.

[0076] The two electrical control cabinets 501 are symmetrically mounted on both sides of the frame 6 in the length direction through mounting brackets 502, which is beneficial to the stability of the center of gravity of the four-way transport vehicle for rail use of the present invention.

[0078] A plurality of battery packs 401 are mounted and fixed on the vehicle frame 6 via mounting brackets 402 .

[0079] The working process of the four-way transport vehicle for track of the present invention is as follows:

[0080] When the electrical control mechanism 5 receives the task instruction, the battery energy mechanism 4 provides electrical energy to the hydraulic mechanism 3, the hydraulic pump station 301 of the hydraulic mechanism 3 works and outputs hydraulic oil to the lifting cylinder 304, the lifting cylinder 304 connects the longitudinal trolley 1 and the frame 6, the lifting of the lifting cylinder 304 causes the longitudinal driving wheel 104 of the longitudinal trolley 1 to contact the longitudinal track, and the transverse trolley 2 is separated from the transverse track, and the track-use four-way transport vehicle of the present invention performs longitudinal track movement; when the electrical control system 5 instructs the track-use four-way transport vehicle of the present invention to perform transverse movement, the hydraulic pump station 301 of the hydraulic structure 3 works, and the reverse hydraulic oil is output through the solenoid valve to retract and descend, the longitudinal trolley 1 is separated from the longitudinal guide rail under the action of the lifting cylinder 304, and the transverse trolley 2 is in contact with the transverse guide rail under the action of the frame 6 and the lifting cylinder 304, and the track-use four-way transport vehicle of the present invention performs transverse track movement, thereby realizing the longitudinal and transverse switching track movement of the track-use four-way transport vehicle of the present invention, achieving the purpose of transporting goods and completing the transportation task.
