Description

Technical Field

[0001] This utility model relates to the field of track joint technology, and in particular to a quick-avoidance joint for gantry crane rails. Background Technology

[0002] In industrial production scenarios, gantry cranes and electric transfer flatcars are key equipment for efficient cargo transfer. They often work together to complete the process of transferring goods from lifting to horizontal transport. The gantry crane travels along fixed rails to lift goods across areas, while the electric transfer flatcar runs along another set of rails to transfer goods lifted by the gantry crane to other work areas. The gantry crane rails and the electric transfer flatcar rails are usually perpendicularly intersecting, inevitably causing structural interference at the intersection. This interference problem directly affects the smooth passage of equipment: when the gantry crane wheels reach the intersection, the rails of the crosscar become obstructed, preventing the gantry crane from passing smoothly; similarly, when the crosscar reaches this position, it will also be obstructed by the gantry crane's rails, not only reducing the efficiency of cargo transfer but also potentially causing equipment failure or safety hazards due to forced passage. Currently, there is no simple and efficient solution in the industry to resolve this rail intersection interference problem. Most methods involve manually dismantling rail joints or adjusting the equipment's travel path, which is cumbersome and time-consuming, severely restricting the continuity and automation level of production operations.

[0003] Therefore, there is an urgent need for a simple and reliable connecting device to enable unimpeded passage between two sets of perpendicularly intersecting rails, thus meeting the actual needs of industrial production for efficient transfer. Summary of the Invention

[0004] To address the aforementioned problems, the purpose of this utility model is to provide a quick-avoidance joint for gantry crane rails, which can effectively solve the structural interference problem when gantry crane rails and electric cross-pass flatcar rails intersect perpendicularly, enabling unobstructed and smooth passage of the two types of equipment at the rail intersection.

[0005] The technical solution adopted in this utility model is as follows: The present invention provides a quick-avoidance joint for gantry crane rails, comprising a fixed rail, a moving rail, and a spring; the fixed rail is fixedly connected to the vertical intersection joint of the rails; the moving rail is slidably fitted inside the fixed rail to connect the fixed rail and a rail perpendicular to the fixed rail; the spring connects the fixed rail and the moving rail.

[0006] Furthermore, the track includes a base and a track; the upper surface of the base has a slide rail; the track is fixedly connected to the outer side of the slide rail; the inner end face of the track has a tenon groove in the middle and spring holes on both sides.

[0007] Furthermore, the track has the same width as the rail.

[0008] Furthermore, a boss corresponding to the width of the tenon groove is provided in the middle of the side of the moving rail opposite to the track, and positioning holes corresponding to the spring holes are opened on both sides; the boss is slidably engaged with the tenon groove; the spring is connected between the spring hole and the positioning hole.

[0009] Furthermore, guide bevels are provided on both sides of the top of the end face of the moving rail away from the fixed rail.

[0010] Furthermore, the moving rail is in close contact with the vertical rail under the action of the spring preload.

[0011] Compared with the prior art, the present invention has the following beneficial effects: This invention enables wheels to move freely on vertical tracks, thus ensuring unobstructed and smooth passage of gantry cranes and electric cross-track flatcars at track intersections. It is also simple in structure and low in cost, and can simplify the operation process, reduce manual intervention, improve cargo transfer efficiency, avoid equipment failures and safety hazards caused by obstruction of passage, and ensure the continuity and automation level of industrial production.

[0016] See appendix Figures 1-5 The present invention discloses a quick-avoidance joint for gantry crane rails, comprising a fixed rail 1, a movable rail 2, and a spring 3. The fixed rail 1 is fixedly connected to the vertical intersection joint of the rails 4; the movable rail 2 is slidably fitted inside the fixed rail 1, used to connect the fixed rail 1 and the rails 4 perpendicular to the fixed rail 1; the spring 3 connects the fixed rail 1 and the movable rail 2; the movable rail 2 is in close contact with the rails 4 in the vertical direction under the preload of the spring 3.

[0017] The fixed rail 1 includes a base 101 and a track 102. A slide rail 105 is formed on the upper surface of the base 101. The track 102 is fixedly connected to the outer side of the slide rail 105. A tenon groove 103 is formed in the middle of the inner end face of the track 102. Two spring holes 104 are formed on the left and right sides of the inner end face of the track 102 for installing springs 3. The track 102 has the same width as the rail 4. The groove width of the slide rail 105 is the same as the width of the moving rail 2.

[0018] A boss 201 corresponding to the width of the tenon 103 is provided in the middle of the end face of the moving rail 2 opposite to the track 102; two positioning holes 202 corresponding to the holes of the spring 104 are respectively opened on the left and right sides of the end face of the moving rail 2 opposite to the track 102 for positioning the spring 3; the boss 201 slides with the tenon 103; the spring 3 is connected one-to-one between the spring hole 104 and the positioning hole 202.

[0019] In this embodiment, guide bevels 203 are provided on the top left and right sides of the end face of the moving rail 2 away from the fixed rail 1, so as to facilitate the engagement of the wheel flange.

[0020] The actual usage process of this utility model is as follows: First, the two perpendicular rails are cut off at the intersection area. Since the wheels of the crossover flatcar are single-flanged, the cut-off position of the gantry crane rail and the side of the crossover flatcar rail are on the same vertical plane; the crossover flatcar rail is cut off on both sides of the node where it intersects with the gantry crane rail. For example... Figure 1 As shown, a set of connectors of this utility model are installed on the three disconnected end faces of the rails.

[0021] First, weld the fixed rail 1 to the cut end face of the rail 4 (3 sets); then, install the four springs 3 into the four spring holes 104 respectively; finally, install the moving rail 2 onto the fixed rail 1, with the lower surface of the moving rail 2 fitting against the slide rail 105, the boss 201 placed in the tenon groove 103, and the four springs inserted into the four positioning holes 202 respectively. At this time, under the preload of the springs 3, the moving rail 2 is pressed against the rail 4 and fits against the side of the rail 4.

[0022] As the gantry crane wheels gradually approach the joint on its rail 4, the guide bevel 203 on the moving rail 2 causes the wheel flange to gradually squeeze into the space between the end face of the moving rail 2 and the side of the rail 4, compressing the moving rail 2 towards the spring 3, thus providing space for the wheel flange to pass and achieving avoidance. After the wheel passes, the moving rail 2 returns to its original state under the action of the spring 3; the same principle applies when the flatcar travels on its rail 4.

[0023] Matters not covered in this utility model are common knowledge.

[0024] The embodiments described above are merely preferred embodiments of the present utility model and are not intended to limit the scope of the present utility model. Various modifications and improvements made to the technical solutions of the present utility model by those skilled in the art without departing from the spirit of the present utility model should fall within the protection scope defined by the claims of the present utility model.
