[0025] The four-way rail connecting device includes a base 30, a movable rail 40 and a linear drive element 50, wherein the base 30 is fixedly arranged between the first rail group 10 and the second rail group 20, wherein the movable rail 40 includes a first movable rail 41 and a second movable rail 42 respectively close to the first rail group 10 and a third movable rail 43 and a fourth movable rail 44 respectively close to the second rail group 20, and the first movable rail 41 and the second movable rail 42 are symmetrically distributed front to back, the third movable rail 43 and the fourth movable rail 44 are symmetrically distributed front to back, and the first movable rail 41 and the third movable rail 43 are symmetrically distributed left to right, and the second movable rail 42 and the fourth movable rail 44 are symmetrically distributed left to right. In addition, the outer end openings of the first movable rail 41 and the second movable rail 42 are in an eight-shaped shape and match the outer end openings of the first rail 11 and the second rail 12. Obviously, the outer end openings of the third movable rail 43 and the fourth movable rail 44 also match the outer end openings of the third rail 21 and the fourth rail 22. The linear drive element 50 is used to drive the first movable rail 41, the second movable rail 42, the third movable rail 43 and the fourth movable rail 44 to move forward and backward, so that the first rail 11, the first movable rail 41, the third movable rail 43 and the third rail 21 are connected (see Figure 1 ), or the first track 11, the first movable track 41, the fourth movable track 44 and the fourth track 22 are connected (see Figure 2 ), or the second track 12, the second movable track 42, the fourth movable track 44 and the fourth track 22 are connected (see Figure 3 ), or the second track 12, the second movable track 42, the third movable track 43 and the third track 21 are connected (see Figure 4 ), which can realize the arbitrary switching of the crossover turnout among the four tracks, is easy to control, can effectively improve the transportation efficiency of the trolley machine, reduce the labor intensity, and greatly improve the safety of the trolley machine transportation.

[0026] The linear drive element 50 is preferably embodied as a hydraulic cylinder.

[0027] In one embodiment, there are four linear drive elements 50, each of which is fixedly mounted on one side of the base 30. The telescopic ends of the four linear drive elements 50 are respectively connected to the first movable rail 41, the second movable rail 42, the third movable rail 43, and the fourth movable rail 44, respectively, for driving each movable rail to move independently to achieve arbitrary switching and connection of the crossover switch among the four tracks.

[0028] In another embodiment, the bottoms of the first movable rail 41 and the second movable rail 42 are simultaneously connected to the first connecting member 411, and the bottoms of the third movable rail 43 and the fourth movable rail 44 are simultaneously connected to the second connecting member 431, wherein the linear drive element 50 is fixedly arranged on one side of the base 30, and the telescopic ends of the linear drive element 50 are respectively connected to the first connecting member 411 and the second connecting member 431, that is, the first connecting member 411 and the second connecting member 431 are respectively driven to move by the linear drive element 50, thereby making the first movable rail 41 and the second movable rail 42 move synchronously, and the third movable rail 43 and the fourth movable rail 44 move synchronously. Compared with the method of driving each movable rail to move separately, it can save equipment costs and reduce the space occupied by equipment.

[0029] Further preferably, there are four linear drive elements 50, wherein the telescopic ends of any two of the linear drive elements 50 are respectively connected to the first connecting member 411, and the telescopic ends of the other two linear drive elements 50 are respectively connected to the second connecting member 431, and the two linear drive elements 50 connecting the first connecting member 411 and the second connecting member 431 are respectively close to the left and right sides of the first connecting member 411 or the second connecting member 431, and cooperate with each other to synchronously drive the first connecting member 411 and the second connecting member 431 to move on both sides, thereby improving the stability of the movement of the first connecting member 411 and the second connecting member 431, thereby ensuring the stability of the movement of the first movable rail 411, the second movable rail 42, the third movable rail 43 and the fourth movable rail 44, and thus ensuring the reliability of the switch connection.

[0030] In one embodiment, the base 30 is composed of multiple seat rails extending along the driving direction of the linear drive element, for example, eight seat rails are evenly spaced between the first and second track groups 10 and 20. The first connector 411 and the second connector 431 are both implemented as channel steels, and rollers 45 are installed within the channel steels to roll with the seat rails. This ensures stable and rapid movement of the first and second connectors 411, 431 under the drive of the linear telescopic element 50, thereby ensuring the movement efficiency and stability of the first, second, third, and fourth movable rails 41, 42, 43, and 44.

[0031] In one embodiment, the seat rails are symmetrically distributed front to back relative to the center line between the first rail 11 and the second rail 12, and the length of the seat rails close to the first rail 11 is greater than the length of the seat rails away from the first rail 11. Therefore, based on the shape and distribution of the movable rails, the length of the seat rails can be minimized while ensuring that sufficient guide travel can be provided, thereby saving equipment costs and reducing the space occupied by equipment.

[0032] It should be noted that the terms "first, second, third and fourth" in this application are used for descriptive purposes only and do not indicate any order. They cannot be understood as indicating or implying relative importance. These terms can be interpreted as names.
