[0027] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0028] See also Figure 1-5 The utility model provides a technical solution, a guide rail structure for a single-beam crane, comprising a plurality of support frames 1, wherein the support frame 1 comprises a vertical beam 1.1, a horizontal beam body 1.2 fixedly connected at one end to the top of the vertical beam 1.1, and a connecting plate 1.3 fixedly connected to the bottom surface of the other end of the horizontal beam body 1.2. The bottom end of the vertical beam 1.1 is fixed to the ground using anchor bolts.

[0029] The two ends of the support plate frame 4 are fixed to the top of the support frame 1. The two ends of the support plate frame 4 are fixedly connected to the corresponding connecting plates 1.3 by bolts; the center of the support plate frame 4 is provided with an axial hole 4.1, and connecting holes 4.2 are opened at the positions on both sides of the axial hole 4.1.

[0030] The servo motor 6 is fixed to the middle of the top surface of the support plate frame 4, and the power output shaft of the servo motor 6 is rotatably sleeved and matched with the shaft hole 4.1.

[0031] A screw rod 7.2 corresponding to the connecting hole 4.2 is vertically fixed on the top surface of the support ring 7, and a locking nut 8 is threadedly sleeved on the top of the screw rod 7.2. That is, the support ring 7 is fixed to the bottom surface of the support plate frame 4 by tightening the locking nut 8. In addition, the outer peripheral wall of the support ring 7 is integrally formed with an annular protrusion 7.1.

[0032] A shaft seat 5.1 is fixed at the center of the top surface of the rotating short rail 5, and a shaft sleeve 5.2 is fixedly sleeved inside the shaft seat 5.1 and matches the fixed sleeve of the power output shaft of the servo motor 6. Connecting blocks 5.3 that are rotatably engaged with the support ring 7 are fixed on both sides of the center of the top surface of the rotating short rail 5. Among them, an arc-shaped slide groove 5.3.1 that is rotatably engaged with the annular protrusion 7.1 is provided on the inner side of the connecting block 5.3.

[0033] The longitudinal track 2 is arranged at the front and rear sides of the rotating short rail 5, and the top surface of the longitudinal track 2 is fixed to the top of the support frame 1; the transverse track 3 is arranged at the left and right sides of the rotating short rail 5, and the top surface of the transverse track 3 is fixed to the top of the support frame 1. Among them, the longitudinal track 2 and the transverse track 3 are respectively fixedly connected to the connecting plate 1.3 by bolts. Each group of transverse tracks 3 and longitudinal tracks 2 are arranged in a cross shape on the periphery of the rotating short rail 5, that is, the rotating short rail 5 can be aligned with the transverse track 3 and the longitudinal track 2 respectively by rotation. When the rotating short rail 5 is aligned with the transverse track 3, a continuous and complete track extending in the horizontal direction can be formed; when the rotating short rail 5 is aligned with the longitudinal track 2, a continuous and complete track extending in the longitudinal direction can be formed. In addition, a plurality of rotating short rails 5 can be provided to cooperate with a plurality of groups of transverse tracks 3 and longitudinal tracks 2 to form a grid-shaped track system.

[0034] In order to ensure that the single-beam crane can smoothly pass through the docking point when the rotating short rail 5 is connected with the transverse track 3 or the longitudinal track 2 after rotation, the two end surfaces of the rotating short rail 5 are arc-shaped convex structures, and the end surfaces of the longitudinal track 2 and the transverse track 3 close to the rotating short rail 5 are arc-shaped concave structures respectively.

[0035] In summary, when in use, the single-beam crane can first move along the longitudinal track 2 or the transverse track 3, and the rotating short rail 5 is correspondingly in a state of docking with the longitudinal track 2 or the transverse track 3. Then the single-beam crane moves as a whole and transitions to the rotating short rail 5, and then the servo motor 6 drives the rotating short rail 5 to rotate 90°, so that the single-beam crane can transition from the longitudinal track 2 to the transverse track 3 or from the transverse track 3 to the longitudinal track 2, thereby increasing the working range covered by the single-beam crane.
