Description

Technical Field

[0001] The utility model relates to the technical field of stacker manufacturing, in particular to a movable and hidden service platform for a stacker. Background Art

[0002] With the acceleration of the pace of economic globalization, the huge potential hidden in automated stereoscopic warehouses has attracted more and more attention. As an important part of the logistics center, an automated stereoscopic warehouse (Automatic Storage & Retrieval System) directly affects the strategies and plans formulated by enterprises, and commands and adjusts the actions of enterprises. Due to the high access efficiency of automated stereoscopic warehouses, they can effectively connect the production links outside the warehouse, form an automated logistics system during storage, and thus form a planned and choreographed production chain, greatly improving production capacity. Automated stereoscopic warehouses have become one of the symbols of enterprise production and management informatization. A stacker is the core equipment of the entire automated stereoscopic warehouse, and it realizes the transportation of goods from one place to another through manual operation, semi-automatic operation or full-automatic operation. The stacker mainly consists of a rack (upper crossbeam, lower crossbeam, column), a driving device, a lifting mechanism, a load platform, a telescopic fork, a service platform and an electrical control system, etc. Among them, the service platform is generally installed at positions such as the top of the column, the middle connection position of the column, below the control cabinet, and below the lifting motor where people need to stand on the stacker, facilitating the maintenance and operation of important positions of the stacker.

[0003] At present, the service platform of the stacker on the market adopts an integrated type, that is, a fixed platform, which requires a relatively large space at both ends of the stacker lane. For some warehouses with a relatively small space at both ends of the lane, the existing integrated service platform of the stacker can only be made relatively small, resulting in a small space for operators to operate on the service platform, which is inconvenient for operation. Since the stacker service platform occupies a large space and a large space is reserved at both ends of the lane, the number of warehouse shelves is reduced, and the utilization rate of the warehouse is lowered. In addition, the existing stacker service platform is relatively large, which is inconvenient for transportation and on-site installation. Since the stacker service platform occupies a large space, the overall appearance of the stacker is not beautiful.

[0004] Therefore, how to solve the deficiencies of the above-mentioned existing technologies has become the subject to be studied and solved in this application. Summary of the Utility Model

The telescopic platform assembly 2 is installed below the fixed platform assembly 1. The telescopic platform assembly 2 slides and connects with the fixed platform assembly 1 and thus retracts into the fixed platform assembly 1. The positioning pin assembly 3 is installed on the fixed platform assembly 1, and the positioning pin assembly 3 fixes the connection between the fixed platform assembly 1 and the telescopic platform assembly 2. By using the fixed platform assembly 1 and the telescopic platform assembly 2 in cooperation, the telescopic platform assembly 2 can be hidden below the fixed platform assembly 1, making the entire service platform occupy a small space and can be used in warehouses with less space at both ends of the stacker aisle.

[0030] The fixed platform assembly 1 includes a fixed platform body 11, a first fixing plate 12, a second fixing plate 13, and a first guardrail 14. The fixed platform body 11 is installed on the stacker column in the horizontal direction.

Second limit blocks 19 are provided at each of the first positioning holes 17, and third limit blocks 10 are provided at each of the second positioning holes 18.

[0031] A proximity switch 4 is installed on the first fixing plate 12 or the second fixing plate 13. The first guardrails 14 are installed in pairs in the vertical direction above both sides of the fixed platform body 11, and the installation sides of the first guardrails 14 are in the same direction as the first guide rail 15 and the second guide rail 16.

[0032] The telescopic platform assembly 2 includes a telescopic platform body 21, a third fixing plate 22, a fourth fixing plate 23, a second guardrail 24 and a ladder 25. The telescopic platform body 21 is horizontally installed below the fixed platform body 11. The third fixing plate 22 and the fourth fixing plate 23 are respectively welded to the lower ends on both sides of the telescopic platform body 21 in the vertical direction. On the side of the third fixing plate 22 away from the fourth fixing plate 23, a first guide wheel set 26 and a first guide block set 27 are installed. The first guide wheel set 26 rotates in the first guide rail 15, and the first guide block set 27 slides along the inner side of the first guide rail 15. On the side of the fourth fixing plate 23 away from the third fixing plate 22, a second guide wheel set and a second guide block set are installed. The second guide wheel set rotates in the second guide rail 16, and the second guide block set slides along the inner side of the second guide rail 16. Third positioning holes and fourth positioning holes are respectively formed at both ends of the third fixing plate 22 and the fourth fixing plate 23 in the same direction as the first guide rail 15 and the second guide rail 16. A fourth limiting block 203 is provided at each third positioning hole, and a fifth limiting block 204 is provided at each fourth positioning hole.

[0033] When the telescopic platform body 21 is not retracted into the fixed platform body 11, the first positioning hole 17 and the second limiting block 19 are located at one end of the first fixing plate 12 and the second fixing plate 13 away from the telescopic platform body 21, while the second positioning hole 18 and the third limiting block 10 are located at one end of the first fixing plate 12 and the second fixing plate 13 close to the telescopic platform body 21. The third positioning hole and the fourth limiting block 203 are located at one end of the third fixing plate 22 and the fourth fixing plate 23 close to the fixed platform body 11, and the fourth positioning hole and the fifth limiting block 204 are located at one end of the third fixing plate 22 and the fourth fixing plate 23 away from the fixed platform body 11. During the process of the telescopic platform body 21 being retracted into the fixed platform body 11, both the third positioning hole and the fourth positioning hole can be aligned with the first positioning hole 17 and the second positioning hole 18.

[0034] The second guardrail 24 is vertically installed above the side end of the telescopic platform body 21, and the ladder 25 is installed below the side end of the telescopic platform body 21.

[0035] The positioning pin assembly 3 includes a positioning pin 31, a positioning plate 32 and a chain 33. One end of the chain 33 is connected to the fixed platform body 11, and the other end is connected to the positioning pin 31. The positioning plate 32 is sleeved on the positioning pin 31.

[0036] Preferably, as shown in Figure 1 , Figure 5 and Figure 6 , a travel switch 5 is installed on the fixed platform body 11 in this embodiment.

[0037] Preferably, as shown in Figure 2 , Figure 4 , Figure 5 and Figure 6As shown in the figure, in this embodiment, a travel switch induction plate 6, a handle 7, and a safety door 8 are installed on the telescopic platform body 21. The handle 7 is welded to the side of the telescopic platform body 21 that is pulled out from the fixed platform body 11, compensating for the shortcoming of the small platform. When working, the staff pulls out the telescopic platform body 21, and the space becomes larger when the staff works on the service platform, facilitating operation. The telescopic platform body 21 of this application is of a manual stretching type. As an implementable method, an automatic stretching type can also be adopted, such as installing a hydraulic cylinder, a cylinder, a screw drive, etc.

[0038] Among them, the fixed platform body 11 is fixed on the stacker column, and the telescopic platform body 21 is installed below the fixed platform body 11. The telescopic platform body 21 rotates along the upper and lower sides of the first guide rail 15 through the first guide wheel set 26, which can be used to adjust the left and right positions of the telescopic platform 2, and the first guide block set 27 slides along the inner side of the first guide rail 15, which can also be used to adjust the left and right positions of the telescopic platform 2. Thus, it slides on the first guide rail 15 and the second guide rail 16 below the fixed platform body 11, so that the telescopic platform body 21 retracts into the fixed platform body 11, and the first guardrail 14 and the second guardrail 24 overlap.

[0039] When the stacker is working, the telescopic platform body 21 is hidden below the fixed platform body 11. At this time, the first limit block 151 on the first guide rail 15 of the fixed platform body 11 contacts the fourth limit block 203 below the telescopic platform body 21, restricting the telescopic platform body 21 from moving forward continuously. At the same time, the first positioning holes 17 on the first fixing plate 12 and the second fixing plate 13 are aligned with the third positioning holes on the third fixing plate 22 and the fourth fixing plate 23. In one group of the first positioning holes 17 and the third positioning holes, the fixed platform assembly 1 and the telescopic platform assembly 2 are double-protected. The positioning pin 31 and the positioning plate 32 are connected to the fixed platform assembly 1 through a chain 33. The positioning plate 32 can rotate into the card slot of the second limit block 19 to prevent the telescopic platform assembly 2 from moving further. Only when the proximity switch 4 on the first fixing plate 12 or the second fixing plate 13 senses the positioning pin 31, and at this time the travel switch 5 on the fixed platform body 11 senses the travel switch induction plate 6 on the telescopic platform body 21, and the stacker can start working only when it receives the signals of the proximity switch 4 and the travel switch 5 simultaneously, which can ensure the safety of the service platform.

[0040] When the stacker is under maintenance or when personnel need to stand on the service platform to increase the working space on the service platform, the staff pulls the telescopic platform body 21 outwards from the fixed platform body 11 by pulling the handle 7 until the first limit block 151 below the first guide rail 15 and the second guide rail 16 on the fixed platform body 11 contacts the fourth limit block 203 below the telescopic platform body 21. At this time, the second positioning holes 18 on the first fixing plate 12 and the second fixing plate 13 below the fixed platform body 11 are aligned with the third positioning holes on the third fixing plate 22 and the fourth fixing plate 23 below the telescopic platform body 21. One set of the second positioning holes 18 and the third positioning holes of the positioning pin 31 provides double protection for the fixed platform assembly 1 and the telescopic platform assembly 2. At this time, the positioning plate 32 rotates into the card slot of the third limit block 10, the proximity switch 4 senses the positioning pin 31, and the travel switch 5 on the fixed platform body 11 is disconnected from the travel switch induction plate 6 on the telescopic platform body 21. At this time, the stacker does not work, and the staff can enter the service platform through the safety door 8 via the ladder 25 to work.

[0041] The first guardrail 14, proximity switch 4, travel switch 5 on the fixed platform assembly 1 and the safety door 8, ladder 25, second guardrail 24 on the telescopic platform assembly 2 can be adjusted or cancelled appropriately according to the application position, scenario and customer requirements of the service platform.

[0042] This application uses the guide wheel set and the guide block set to move in the sliding guide rail, which is convenient to operate, light and sensitive, increases the platform operation space, reduces the reserved space at both ends of the roadway, and increases the utilization rate of the warehouse shelves. The service platform of this application is small, saves space during transportation, reduces transportation costs, and is easy to install. At the same time, it is convenient to operate, light and sensitive, making the overall appearance of the stacker more beautiful and coordinated.

[0043] The above description of the disclosed embodiments enables those skilled in the art to implement or use the present invention. Various modifications to these embodiments will be obvious to those skilled in the art, and the general principles defined herein can be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention will not be limited to the embodiments shown herein, but rather to the widest scope consistent with the principles and novel features disclosed herein.
