Description

Technical Field

[0001] The utility model relates to the technical field of stacker equipment, in particular to an adaptive double-spring adjustable swing guide wheel device for a stacker load platform. Background Art

[0002] A stacker is the most core logistics handling equipment in modern intelligent warehousing, mainly performing functions such as outbound, inbound, and turnover. The high efficiency and wide application range of stackers are the trends for future sustainable development. During the use of a stacker, since most stackers adopt double columns, that is, the load platform is installed between the two columns, and the lifting mechanism of the load platform drives the load platform to perform a linear motion of lifting or lowering along the columns. During the movement, there is a gap reserved during the design between the load platform and the columns, and during the movement, this gap will cause the load platform to swing left and right. At this time, a guide wheel device needs to be added to make this movement process stable.

[0003] In the existing technology, the load platform guide wheel device mostly uses methods such as shim adjustment, or using an eccentric shaft, or using a single-spring adjustable swing guide wheel device to adjust the gap distance between the guide wheel device and the column. In each adaptive adjustment of the single-spring adjustable swing guide wheel device, the heavy rectangular spring is subjected to too much force, resulting in too much force on the bearing of the guide wheel device during the lifting process, generating harsh abnormal noises and wearing the contact surface of the T-shaped guide rail. Moreover, the single-spring control of the guide wheel device will cause the center of the guide wheel device to be deviated, and it will swing left and right within the size range of the waist-shaped hole for threading bolts on its bracket, which will wear the service life of the bracket in the device for a long time. And the bending plate of the rotating shaft mounting hole of this device is welded to the load platform. After being stressed for a long time, the shaft-passing hole of this mounting plate will be worn, and it cannot be directly replaced. Only by re-cutting and welding can it be done, resulting in a great reduction in accuracy and difficult maintenance. Content of the Utility Model

[0004] The applicant of the present invention aims at the above-mentioned shortcomings in the existing production technology, and provides an adaptive double-spring adjustable swing guide wheel device for a stacker load platform, so as to achieve uniform force on the entire guide wheel device, avoid the problem of central deviation, and facilitate the adjustment of the gap between the guide wheel and the column.

[0005] The technical solution adopted by the present utility model is as follows: An adaptive double-spring adjustable swing guide wheel device for a stacker load platform, comprising a load platform that moves up and down along the vertical direction of the stacker column. Guide wheel devices are provided at the contact ends of both sides of the load platform and the stacker column, and the guide wheel devices are in contact with the stacker column; the structure of the guide wheel device is: including a rotating shaft mounting seat installed on the load platform, the rotating shaft mounting seat is welded and fixed to the shaft hole bracket, a rotating shaft is installed on the shaft hole bracket, a guide wheel bracket is arranged on the rotating shaft, and bearings are assembled between the guide wheel brackets. The upper guide wheel bracket and the lower guide wheel bracket are welded integrally, and a double-spring assembly is arranged on the lower guide wheel bracket; the upper guide wheel bracket and the lower guide wheel bracket rotate together with the rotating shaft and adjust the gap between the bearing and the stacker column through the double-spring assembly.

[0006] As a further improvement of the above technical solution:

[0007] Preferably, the structure of the double-spring assembly is: a medium-sized rectangular spring is installed at each of the left and right positions of the lower guide wheel bracket.

[0008] Preferably, each medium-sized rectangular spring is fixed to the load platform through a stud and a nut. The stud penetrates through the side plate of the load platform, and nuts are arranged at both ends of the stud.

[0009] Preferably, the bearing is assembled on the upper guide wheel bracket through a shaft, and the bearing rotates with the shaft.

[0010] Preferably, shaft retaining rings are arranged on both sides of the shaft, and the shaft retaining rings are installed in cooperation with the card slots of the shaft.

[0011] Preferably, the threaded clearance hole between the rotating shaft mounting seat and the load platform is connected through a bolt passing through, and a nut matching the mounting seat locking bolt is arranged on the other side of the load platform.

[0012] Preferably, a flat washer is also arranged on the contact surface between the mounting seat bolt and the load platform.

[0013] The beneficial effects of the present utility model are as follows:

[0014] The structure of the present utility model is compact and the operation process is convenient. The gap between the bearing and the column can be adjusted through the double-spring assembly by rotating the shaft. At the same time, the present utility model adopts double springs installed at the left and right positions of the lower guide wheel bracket to replace the traditional single-spring installation method at the exact center, so as to achieve uniform force on the guide wheel device and avoid the problem of central deviation.

[0015] The present utility model also has the following advantages:

[0016] (1) The double-spring structure of the present utility model uses medium-sized rectangular springs, while the single spring in the current prior art uses heavy-duty rectangular springs. The spring force of the heavy-duty rectangular spring is too large to effectively control the force. After forming a double spring with medium-sized rectangular springs, the force can be evenly distributed and the cost is reduced;

[0017] (2) The shaft hole bracket of the present utility model is connected to the rotary shaft mounting seat. The rotary shaft mounting seat uses a bolt fixing method instead of welding to the cargo platform body, achieving the advantages of convenient disassembly during maintenance and easy replacement when worn. At the same time, the difficulty of the installation process of the entire guide wheel device is also reduced. BRIEF DESCRIPTION OF THE DRAWINGS
