Description

Technical Field

[0001] This invention relates to a hoist in an automated storage and retrieval system, and more particularly to a flexible loading platform mechanism for a hoist used to lift extra-long profile materials. Background Technology

[0002] The main structure of the hoist consists of a liftable loading platform positioned between two parallel portal frames. A lifting drive mechanism for the loading platform is located at the top of each portal frame, connected to the platform to drive its lifting. Lifting guide wheel mechanisms are located on both sides of the loading platform, with the guide wheels positioned within the lifting tracks of the portal frames. When the lifting drive mechanism moves the loading platform, the guide wheels on both sides rise or fall along the vertical tracks on the portal frames to guide the platform. To enhance the stability of the two portal frames, horizontal tie beams are typically connected at intervals along the front and rear sides of each frame, running from bottom to top. These tie beams, together with the two portal frames, form a stable three-dimensional frame structure. However, when the hoist is used to lift extra-long profile rods, due to the length of the rods… The length of the material is much greater than the width of each portal frame, meaning that the profile rods placed on the loading platform will protrude beyond the platform's outer edge. To achieve unobstructed lifting of the lifting platform carrying these extra-long rods, a crossbeam cannot be installed in the middle of the two portal frames to avoid interference between the protruding rods and the crossbeam. Instead, a top crossbeam can be installed at the top of the two portal frames. When the lifting height is large, the vertical columns of the extra-long lifting machine portal frames will undergo flexible deformation, resulting in a difference in the spacing between the lifting tracks of the two portal frames. Furthermore, since the guide wheel mechanisms on both sides of the loading platform frame are rigidly connected to the loading platform, the inconsistent spacing of the vertical tracks on the columns causes severe wear on the lifting guide wheel mechanisms on both sides when the loading platform is lifted, which can directly lead to jamming during lifting. How to solve this problem is a topic that needs to be studied on-site. Summary of the Invention

[0003] This invention provides a flexible cargo platform mechanism for lifting ultra-long profile materials, which solves the technical problem that the lifting platform will get stuck during lifting when the gantry column of the ultra-high lifting machine undergoes flexible deformation.

[0004] The present invention solves the above technical problems through the following technical solutions: A flexible loading platform mechanism for lifting extra-long profile materials includes a left gantry frame and a right gantry frame. A lifting loading platform is arranged between the left and right gantry frames. A left-side hanger of the loading platform is arranged on the right side of the left gantry frame, and a right-side hanger of the loading platform is arranged on the left side of the right gantry frame. The drive mechanism of the lifting platform is connected to the left-side hanger of the loading platform via a left lifting chain, and the drive mechanism of the lifting platform is connected to the right-side hanger of the loading platform via a right lifting chain. A left front pin bearing is fixedly connected to the front right side of the left hanger of the loading platform, and a left rear pin bearing is fixedly connected to the rear right side of the left hanger of the loading platform. A left rear pin bearing is fixedly connected to the front left side of the right hanger of the loading platform. A right front pin seat is fixedly connected to the side, and a right rear pin seat is fixedly connected to the left rear end of the right-side lifting frame of the loading platform; a left front pin is provided on the left front pin seat in a horizontal direction, and a left swing arm is hinged to both ends of the left front pin, with the lower end of the left swing arm hinged to the left end of the lifting loading platform; a hinged swing arm mechanism with the same structure as the one on the left front pin seat is provided on the left rear pin seat; a right front pin is provided on the right front pin seat, and a right swing arm is hinged to both ends of the right front pin, with the lower end of the right swing arm hinged to the right end of the lifting loading platform; a hinged swing arm mechanism with the same structure as the one on the right rear pin seat is provided on the right rear pin seat.

[0005] The left-side portal frame consists of a left front column, a left rear column, and a left top longitudinal beam; the right-side portal frame consists of a right front column, a right rear column, and a right top longitudinal beam. A top front crossbeam is installed between the tops of the left and right front columns, and a top rear crossbeam is installed between the left and right rear columns. Extra-long profile materials are placed on the lifting loading platform along the front-back direction.

[0006] A left front guide wheel track is installed on the front side of the left front column, and a left rear guide wheel track is installed on the rear side of the left rear column. A left front lower guide wheel connecting rod and a left front upper guide wheel connecting rod are respectively installed on the front column of the left side hanger of the loading platform. The left front lower guide wheel at the outer end of the left front lower guide wheel connecting rod is movably mounted in the left front guide wheel track, and the left front upper guide wheel at the outer end of the left front upper guide wheel connecting rod is movably mounted in the left front guide wheel track. A left rear lower guide wheel connecting rod and a left rear upper guide wheel connecting rod are respectively installed on the rear column of the left side hanger of the loading platform. The left rear lower guide wheel at the outer end of the left rear lower guide wheel connecting rod is movably mounted in the left rear guide wheel track, and the left rear upper guide wheel at the outer end of the left rear upper guide wheel connecting rod is movably mounted in the left rear guide wheel track. A right guide wheel mechanism identical to the guide wheel mechanism on the left side hanger of the loading platform is installed on the right side hanger of the loading platform.

[0007] This invention transforms the conventional method of rigidly connecting the loading platform to the lifting brackets on both sides into a method of hinged swinging connection between the lifting brackets on both sides and the loading platform. The loading platform can swing left and right around the lifting brackets to a certain extent, thereby completely solving the problem of the loading platform getting stuck due to the deformation of the portal column causing the lifting brackets to move left and right during lifting. This invention has a simple structure and is easy to implement on site. Attached Figure Description

[0009] The present invention will now be described in detail with reference to the accompanying drawings: A flexible loading platform mechanism for lifting extra-long profile materials includes a left portal frame and a right portal frame. A lifting loading platform 5 is arranged between the left and right portal frames. Extra-long profile materials 26 are placed on the lifting loading platform 5 along the front-to-back direction. The length of the extra-long profile material 26 is much longer than the width of the two portal frames. Therefore, the front and rear ends of the extra-long profile material 26 are both cantilevered on the outside of the lifting loading platform 5. The lifting loading platform 5 carries the extra-long profile material 26 up and down to achieve lifting and transfer of the extra-long profile material 26. A left-side hanger 7 of the loading platform is arranged on the right side of the left portal frame. A right-side lifting bracket 8 for the loading platform is located on the left side of the frame. The drive mechanism of the lifting platform is connected to the left-side lifting bracket 7 of the loading platform via a left lifting chain 9, and the drive mechanism of the lifting platform is connected to the right-side lifting bracket 8 of the loading platform via a right lifting chain 10. The lifting drive mechanism of the lifting platform achieves lifting and lowering of the platform via the lifting chains. A left front pin seat 11 is fixedly connected to the front right side of the left-side lifting bracket 7, and a left rear pin seat 12 is fixedly connected to the rear right side of the left-side lifting bracket 7. A right front pin seat 13 is fixedly connected to the front left side of the right-side lifting bracket 8, and a right rear pin seat 13 is fixedly connected to the rear left side of the right-side lifting bracket 8. There is a right rear pivot seat 14; a left front pivot 15 is provided on the left front pivot seat 11, running horizontally in the front-rear direction, and a left swing arm 16 is hinged to both ends of the left front pivot 15, with the lower end of the left swing arm 16 hinged to the left end of the lifting platform 5; a hinged swing arm mechanism with the same structure as that on the left front pivot seat 11 is provided on the left rear pivot seat 12, and a pair of left front swing arm mechanisms are hinged and suspended to the left front end of the platform 5; a right front pivot 17 is provided on the right front pivot seat 13, and a right swing arm 18 is hinged to both ends of the right front pivot 17, with the lower end of the right swing arm 18 hinged to the lifting platform The right ends of 5 are hinged together; a hinged swing arm mechanism with the same structure as the one on the right front pin seat 13 is provided on the right rear pin seat 14; the four sets of hinged hoisting mechanisms realize the hinged hoisting of the four corners of the lifting platform 5, so that the lifting platform 5 can swing left and right between the lower end of the left side hanger 7 and the lower end of the right side hanger 8 of the platform, realizing the flexible connection between the platform and the two side hangers; if the distance between the left side hanger 7 and the right side hanger 8 of the platform changes during the lifting process, the change will be absorbed by the swing of the platform, thereby avoiding the platform from getting stuck during the lifting process.

[0010] The left portal frame consists of a left front column 1, a left rear column 3, and a left top longitudinal beam. The left portal frame is arranged along the front-to-back direction. The right portal frame consists of a right front column 2, a right rear column 4, and a right top longitudinal beam. The right portal frame is also arranged along the front-to-back direction. The frame of this invention can only have a top front crossbeam 6 between the top of the left front column 1 and the top of the right front column 2, and a top rear crossbeam between the left rear column 3 and the right rear column 4. Since extra-long profile materials 26 are placed on the lifting loading platform 5 along the front-to-back direction, if a left-to-right connecting crossbeam is set in the lower part of the two portal frames... The beams would cause interference between the cantilevered extra-long profile material 26 and the lower left and right crossbeams. For this reason, the left and right connection stiffness between the two portal frames is limited. When the lifting height is large, the portal column will deform in the vertical direction, which will cause a large change in the distance between the left and right portal columns. This will also change the distance between the two hangers guided by the vertical track on the portal column. The structure of this invention, which hinges the loading platform to the two lifting frames below, overcomes the above defects very well. By cleverly swinging the loading platform with hinges, the lifting of the loading platform is smooth.

[0011] A left front guide wheel track 19 is provided on the front facade of the left front column 1, and a left rear guide wheel track 20 is provided on the rear facade of the left rear column 3. A left front lower guide wheel connecting rod 21 and a left front upper guide wheel connecting rod 22 are respectively provided on the front column of the left side hanger 7 of the loading platform. The left front lower guide wheel 23 at the outer end of the left front lower guide wheel connecting rod 21 is movably mounted in the left front guide wheel track 19, and the left front upper guide wheel 24 at the outer end of the left front upper guide wheel connecting rod 22 is movably mounted in the left front guide wheel track 19. In the left front guide wheel track 19; on the rear column of the left side hanger 7 of the loading platform, a left rear lower guide wheel connecting rod and a left rear upper guide wheel connecting rod are respectively provided. The left rear lower guide wheel at the outer end of the left rear lower guide wheel connecting rod is movably set in the left rear guide wheel track 20, and the left rear upper guide wheel 25 at the outer end of the left rear upper guide wheel connecting rod is movably set in the left rear guide wheel track 20; on the right side hanger 8 of the loading platform, a right guide wheel mechanism that is exactly the same as the guide wheel mechanism on the left side hanger 7 of the loading platform is provided.
