Description

Technical Field

[0001] This application relates to the field of cross-rail technology, and in particular to a cross-rail installation structure for a gantry crane. Background Technology

[0002] Gantry cranes, as a common type of lifting equipment, are widely used in construction, manufacturing, and logistics. The design of their track system is crucial for improving operational efficiency and safety. Traditional gantry crane track systems typically employ a straight layout to meet basic lifting and transportation needs. However, in some complex operating environments, such as large precast beam yards or heavy machinery manufacturing workshops, a unidirectional track layout cannot meet multi-dimensional transportation requirements.

[0003] To overcome the limitations of unidirectional tracks, cross-track systems have emerged. This system consists of two sets of perpendicularly intersecting tracks, forming a cross shape, allowing the gantry crane to move independently in both the X and Y directions. Existing cross-track systems typically use connecting tracks to address the connection problem at track intersections. For example, some designs incorporate rotatable connecting tracks at intersections. When the gantry crane reaches an intersection, the connecting track needs to be removed and rotated into the corresponding track to maintain track continuity. Furthermore, rotating lifting mechanisms are used to automatically control the lifting and rotation of the connecting tracks, thereby improving automation and work efficiency.

[0004] While existing cross-track systems have improved the flexibility and operating range of gantry cranes to some extent, some problems remain. For example, when two sets of tracks are running simultaneously, collisions may occur. This is because the operation of the gantry crane at the intersection requires precise scheduling and control; if the adjustment of the connecting tracks is not timely or in place, collisions may occur at the intersection. Utility Model Content

[0005] The purpose of this application is to address the problem that in existing cross-rail systems, untimely or inadequate adjustment of the connecting rails may cause the gantry crane to collide at the intersection, affecting system safety. This application provides a cross-rail installation structure for gantry cranes.

[0006] To achieve the above objectives, this application specifically adopts the following technical solution:

[0007] A cross-track installation structure for a gantry crane includes a base, a steering platform rotatably connected to the top of the base, a steering rail fixedly connected to the top of the steering platform, and limit plates symmetrically fixedly connected to the top of the steering platform. Longitudinal rails and transverse rails are symmetrically fixedly connected to one end of the base, with the two longitudinal rails and two transverse rails arranged perpendicularly. The steering platform is installed at the intersection of the two longitudinal rails and the two transverse rails. An adjustment assembly for driving the steering platform to rotate is installed inside the base.

[0008] By adopting the above technical solution, and by setting the adjustment component to work in conjunction with the steering rail and the limiting plate, it is easy to activate the adjustment component to drive the steering table to rotate the steering rail to align with the longitudinal or transverse rail as needed. At the same time, the limiting plate will block the movement of the longitudinal or transverse rail, thereby effectively reducing the mutual interference between the device in the two directions of the longitudinal and transverse rails and improving the safety of the device.

[0009] Furthermore, the adjustment assembly includes a mounting compartment formed inside the base, one end of the steering platform extends into the mounting compartment and is fixedly connected to a steering worm gear, a steering worm gear meshing with the steering worm gear is rotatably connected inside the mounting compartment, a steering motor is fixedly connected inside the mounting compartment, and the output end of the steering motor is fixedly connected to the steering worm gear.

[0010] By adopting the above technical solution, and by setting up the cooperation between the steering worm gear and the steering worm, the starting steering motor can drive the steering worm to mesh with the steering worm gear, and drive the steering worm gear to rotate. At the same time, the steering worm gear drives the steering table and the steering rail to rotate, which effectively improves the practicality of the device.

[0011] Furthermore, the top of the base is provided with an annular slide rail, and a plurality of support balls are evenly installed at one end of the steering table. One end of the support balls rolls against the steering table, and the other end of the support balls is installed inside the annular slide rail.

[0012] By adopting the above technical solution, and by setting up the cooperation between the annular slide rail and the support ball bearings, it is convenient for the support ball bearings to roll along the inner wall of the annular slide rail when the steering table is rotated. This effectively increases the rolling contact area between the steering table and the base, and effectively improves the support strength and rotational stability of the steering table.

[0013] Furthermore, multiple pointed protrusions are uniformly and fixedly connected to the periphery of the steering platform.

[0014] By adopting the above technical solution, the friction of the outer periphery of the steering table is effectively improved by setting sharp protrusions. This facilitates the movement of foreign objects remaining between the steering table and the longitudinal and transverse tracks when the steering table rotates, thereby reducing the possibility of foreign objects blocking the gaps between the steering table and the longitudinal and transverse tracks and affecting the safety of the system.

[0015] Furthermore, an annular transmission groove is provided at one end of the steering platform, and a conical ring is rotatably connected inside the annular transmission groove. A transmission component for driving the conical ring to rotate is installed at one end of the steering platform.

[0016] By adopting the above technical solution, and by setting up the transmission component and the conical ring to work together, it is convenient for the transmission component to drive the conical ring to rotate in the opposite direction when the steering table is rotating. This allows the foreign objects pushed by the steering table and the pointed protrusions to be affected by the centrifugal force generated by the rotation of the conical ring. As the foreign objects slide onto the surface of the conical ring, they fly outwards along the surface of the conical ring, thereby effectively reducing the accumulation of foreign objects between the steering table and the longitudinal and transverse tracks, and improving the practicality of the device.

[0017] Furthermore, the transmission assembly includes a transmission chamber opened inside the base, one end of the transmission chamber having a transmission port communicating with an annular transmission groove, one end of the conical ring being fixedly connected to a transmission gear ring, one end of the steering platform extending into the interior of the transmission chamber and being fixedly connected to a drive gear, and a driven gear meshing with the drive gear being rotatably connected inside the annular transmission groove, one end of the driven gear meshing with the transmission gear ring.

[0018] By adopting the above technical solution, and by setting up the cooperation of the driving gear, driven gear, and transmission gear ring, when the steering table drives the driving gear to rotate, the driving gear meshes with the driven gear, and drives the driven gear to mesh with the transmission gear ring, thereby driving the transmission gear ring to drive the conical ring to rotate with the steering table, which effectively improves the practicality of the device.

[0019] Furthermore, the surface of the conical ring is uniformly provided with multiple friction grooves.

[0020] By adopting the above technical solution, the friction force on the surface of the conical ring is effectively improved by setting friction grooves, thereby increasing the efficiency of the conical ring in moving foreign objects and further improving the practicality of the device.

[0021] Furthermore, each of the longitudinal and transverse tracks has a symmetrically provided positioning groove at one end, and a positioning rod is inserted into the positioning groove. The positioning rod is installed between adjacent longitudinal and transverse tracks.

[0022] By adopting the above technical solution, and by setting up the positioning rod and positioning groove in cooperation, it is convenient to fix the installation angle between adjacent longitudinal and transverse tracks by positioning rod, so as to reduce the problem of loosening of longitudinal and transverse tracks and affecting system safety.

[0023] In summary, this application includes at least one of the following beneficial effects:

[0024] 1. By setting the adjustment component to work in conjunction with the steering rail and limit plate, the adjustment component can be activated to drive the steering table to rotate the steering rail to align with the longitudinal or transverse rail as needed. At the same time, the limit plate can block the movement of the longitudinal or transverse rail, thereby effectively reducing the mutual interference between the device in the two directions of the longitudinal and transverse rails and improving the safety of the device.

[0025] 2. By using the transmission component in conjunction with the conical ring, the transmission component can drive the conical ring to rotate in the opposite direction when the steering table is rotating. This allows the foreign objects pushed by the steering table and the pointed protrusions to be affected by the centrifugal force generated by the rotation of the conical ring. As the foreign objects slide onto the surface of the conical ring, they fly outwards along the surface of the conical ring, thereby effectively reducing the accumulation of foreign objects between the steering table and the longitudinal and transverse tracks, and improving the practicality of the device.

[0032] The following is in conjunction with the appendix Figure 1—4 provides further detailed description of this application.

[0033] This application discloses a cross-shaped track installation structure for a gantry crane.

[0034] Reference Figure 1 - Figure 3 A cross-track installation structure for a gantry crane includes a base 1, a turntable 2 rotatably connected to the top of the base 1, a turntable 3 fixedly connected to the top of the turntable 2, and limit plates 4 symmetrically fixedly connected to the top of the turntable 2. Longitudinal rails 5 and transverse rails 6 are symmetrically fixedly connected to one end of the base 1. The two longitudinal rails 5 and the two transverse rails 6 are arranged perpendicularly. The turntable 2 is installed at the intersection of the two longitudinal rails 5 and the two transverse rails 6. An adjustment component for driving the turntable 2 to rotate is installed inside the base 1.

[0035] The adjustment assembly includes a mounting chamber 7 inside the base 1, one end of the steering platform 2 extends into the mounting chamber 7 and is fixedly connected to a steering worm gear 8, a steering worm 9 that meshes with the steering worm gear 8 is rotatably connected inside the mounting chamber 7, a steering motor 10 is fixedly connected inside the mounting chamber 7, and the output end of the steering motor 10 is fixedly connected to the steering worm 9.

[0036] Furthermore, the top of the base 1 is provided with an annular slide rail 11, and a plurality of support balls 12 are evenly installed on one end of the steering table 2. One end of the support balls 12 rolls against the steering table 2, and the other end of the support balls 12 is installed inside the annular slide rail 11.

[0037] When in use, firstly, when using the longitudinal track 5 as the direction of movement, the steering motor 10 is started to drive the steering worm 9 to rotate, and the steering worm 9 is driven to mesh with the steering worm wheel 8, so that the steering worm wheel 8 drives the steering platform 2 and the steering rail 3 to rotate. At the same time, the steering rail 3 rotates to a position parallel to and aligned with the longitudinal track 5. When the steering platform 2 rotates, it drives the limiting plate 4 to rotate to a position perpendicular to and aligned with the transverse track 6, so that the limiting plate 4 blocks the device moving in the direction of the transverse track 6, thereby reducing the collision between the device in the direction of the longitudinal track 5 and the transverse track 6.

[0038] Similarly, when using the transverse track 6 as the direction of movement, the steering motor 10 is activated to drive the steering worm 9 to mesh with the steering worm wheel 8, causing the steering rail 3 to rotate to a position parallel and aligned with the transverse track 6. At the same time, the limiting plate 4 is rotated to a position perpendicular to the longitudinal track 5 to block the device moving in the direction of the longitudinal track 5, reducing the collision between the device in the direction of the longitudinal track 5 and the transverse track 6. While driving the steering table 2 to rotate, the steering table 2 causes the support ball 12 to roll along the inner wall of the annular slide rail 11, increasing the rolling support area between the steering table 2 and the base 1, thereby effectively improving the stability of the steering table 2 during rotation. This facilitates free movement in both the longitudinal track 5 and the transverse track 6, reduces mutual interference between the devices in the two directions of the longitudinal track 5 and the transverse track 6, and improves the safety of the device.

[0039] Reference Figure 2 - Figure 4 Multiple sharp protrusions 13 are evenly fixedly connected to the outer periphery of the steering platform 2;

[0040] One end of the steering platform 2 is provided with an annular transmission groove 14, and a conical ring 15 is rotatably connected inside the annular transmission groove 14. A transmission component for driving the conical ring 15 to rotate is installed at one end of the steering platform 2.

[0041] Furthermore, the transmission assembly includes a transmission chamber 20 opened inside the base 1. One end of the transmission chamber 20 is provided with a transmission port 22 communicating with the annular transmission groove 14. One end of the conical ring 15 is fixedly connected to a transmission gear ring 16. One end of the steering platform 2 extends into the interior of the transmission chamber 20 and is fixedly connected to a drive gear 17. The interior of the annular transmission groove 14 is rotatably connected to a driven gear 18 that meshes with the drive gear 17. One end of the driven gear 18 meshes with the transmission gear ring 16.

[0042] Furthermore, the surface of the conical ring 15 is uniformly provided with multiple friction grooves 19.

[0043] In use, when the steering table 2 rotates, it causes the drive gear 17 to mesh with the driven gear 18, and the driven gear 18 to mesh with the transmission gear ring 16. The transmission gear ring 16 then drives the conical ring 15 to rotate in the opposite direction to the steering table 2. As the steering table 2 rotates the pointed protrusion 13 and pushes the foreign objects remaining in the gap between the longitudinal track 5 and the transverse track 6, the transmission gear ring 16 drives the conical ring 15 to rotate in the opposite direction to the steering table 2. This causes the foreign objects pushed by the pointed protrusion 13 to slide along the surface of the conical ring 15. At the same time, the foreign objects are affected by centrifugal force and fly out around the surface of the conical ring 15. The friction groove 19 effectively increases the friction of the surface of the conical ring 15, improving the efficiency of the conical ring 15 in removing foreign objects from the steering table 2 between the longitudinal track 5 and the transverse track 6. This facilitates the automatic cleaning of foreign objects between the steering table 2 and the longitudinal track 5 and the transverse track 6, effectively improving the safety of the system.

[0044] Reference Figure 1 and Figure 2 The longitudinal track 5 and the transverse track 6 are symmetrically provided with positioning grooves at one end. Positioning rods 21 are inserted into the positioning grooves and are installed between adjacent longitudinal tracks 5 and transverse tracks 6.

[0045] In use, after the longitudinal rail 5 and the transverse rail 6 are installed, the two ends of the traction positioning rod 21 are inserted into the positioning grooves opened at one end of the adjacent longitudinal rail 5 and transverse rail 6, respectively, thereby fixing the included angle between the adjacent longitudinal rail 5 and transverse rail 6, reducing the possibility of the included angle between the longitudinal rail 5 and transverse rail 6 being offset by external forces, and improving the safety of the system.

[0046] The implementation principle of the cross-track installation structure of the gantry crane in this embodiment is as follows: First, the two ends of the traction positioning rod 21 are respectively inserted into the positioning grooves opened at one end of the adjacent longitudinal track 5 and the transverse track 6, thereby fixing the included angle between the adjacent longitudinal track 5 and the transverse track 6, so as to reduce the situation where the included angle between the longitudinal track 5 and the transverse track 6 is deviated by external force. Then, when the longitudinal track 5 is used as the direction of movement, the steering motor 10 is started to drive the steering worm 9 to rotate, and the steering worm 9 is driven to mesh with the steering worm wheel 8, so that the steering worm wheel 8 drives the steering platform 2 and the steering rail 3 to rotate. At the same time, the steering rail 3 rotates to a position parallel to the longitudinal track 5. When the steering platform 2 rotates, it drives the limiting plate 4 to rotate to a position perpendicular to the transverse track 6, so that the limiting plate 4 resists and intercepts the device moving in the direction of the transverse track 6, thereby reducing the collision between the device in the direction of the longitudinal track 5 and the transverse track 6.

[0047] Similarly, when using the transverse track 6 as the direction of movement, the steering motor 10 is started to drive the steering worm 9 to mesh with the steering worm wheel 8, causing the steering rail 3 to rotate to a position parallel to and aligned with the transverse track 6. At the same time, the limiting plate 4 is rotated to a position perpendicular to the longitudinal track 5 to block the device moving in the direction of the longitudinal track 5, reducing the collision between the device in the direction of the longitudinal track 5 and the transverse track 6. While driving the steering table 2 to rotate, the steering table 2 causes the support ball 12 to roll along the inner wall of the annular slide rail 11, increasing the rolling support area between the steering table 2 and the base 1, thereby effectively improving the stability of the steering table 2 when rotating.

[0048] Furthermore, when the steering platform 2 rotates, it causes the driving gear 17 to mesh with the driven gear 18, and simultaneously causes the driven gear 18 to mesh with the transmission gear ring 16, driving the transmission gear ring 16 to drive the conical ring 15 to rotate in the opposite direction to the steering platform 2. As the steering platform 2 drives the pointed protrusion 13 to rotate and pushes the foreign objects remaining in the gap between the longitudinal track 5 and the transverse track 6 to move, the transmission gear ring 16 drives the conical ring 15 to rotate in the opposite direction to the steering platform 2, causing the foreign objects pushed by the pointed protrusion 13 to slide along the surface of the conical ring 15. At the same time, the foreign objects are affected by centrifugal force and fly out around the surface of the conical ring 15.
