Description

Technical Field

[0001] This utility model relates to the technical field of shelving, specifically to a special shelving system for ladders. Background Technology

[0002] During the production process, racks are needed for handling and storing workpieces. If workpieces are prone to shaking when placed on racks, scratches can easily appear on their surfaces, affecting product quality. Therefore, it is essential to ensure the workpieces remain stable on the racks. In compressor units, ladders are installed for easy access and maintenance. These ladders require a rust-preventive painting process before installation; therefore, it is crucial to prevent any wear or damage to the paint surface before installation.

[0003] Chinese utility model patent CN215923364U discloses a novel shelf for easy material handling, comprising a frame and a tray mounted on the frame. The tray has multiple positioning units for holding and positioning workpieces. Each positioning unit includes a corresponding positioning groove and a positioning notch. Both the positioning groove and the positioning notch are V-shaped, and the height of the positioning notch is higher than the height of the positioning groove. The two ends of the workpiece are respectively supported on the corresponding positioning groove and positioning notch. The workpiece is inclined, and its corresponding end face is supported on the positioning groove. Because the positioning groove and positioning notch for workpiece positioning are both V-shaped, and the positioning notch is higher than the positioning groove, even with a small deviation between the workpiece grasped by the robotic arm and the positioning groove and positioning notch, the workpiece can automatically slide into the positioning groove and positioning notch. Therefore, the precision requirements for the robotic arm are lower, and the robotic arm can handle workpiece handling more simply and quickly, thus improving work efficiency.

[0004] The existing technology lacks a rack that can stably fix the ladder, which makes the ladder prone to shaking and bumping during storage and transportation, negatively impacting product quality. Therefore, the existing technology has a technical problem of unstable workpieces on the rack. Utility Model Content

Detailed Implementation

[0025] To make the objectives, technical solutions and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the embodiments. However, the scope of protection of this utility model is not limited to the specific embodiments described below.

[0026] refer to Figure 1-4 A special rack for climbing ladders includes a support frame and a clamping assembly 21, which is mounted on the support frame.

[0027] There are four clamping assemblies 21, which are respectively arranged on both sides of the support frame, with two clamping assemblies 21 on each side. Synchronous pressure rods 44 are provided between adjacent clamping assemblies 21, and the synchronous pressure rods 44 are fixedly connected to the drive rods 41 in the two clamping assemblies 21. The support frame includes an outer beam 11, an inner beam 12, a connecting rod 13, and a column 14. The outer beam 11 and the connecting rod 13 are both fixedly connected to the column 14. The inner beam 12 is fixedly connected to the connecting rod 13, and the fixing plate 31 is fixedly connected to the connecting rod 13. The inner beam 12 is located between the two clamping assemblies 21. A connecting sleeve 15 is fixedly connected to the lower end of the column 14. The connecting sleeve 15 has a connecting groove 16 with a width greater than that of the column 14.

[0028] The clamping assembly 21 includes a rotating sleeve 22, a buckle plate 23, a push rod 24, and a locking mechanism. The rotating sleeve 22 is rotatably connected to the support frame and the connecting rod 13. The buckle plate 23 and the push rod 24 are both fixedly connected to the rotating sleeve 22. The buckle plate 23 is located above the support frame, and the end of the buckle plate 23 away from the rotating sleeve 22 is bent towards the support frame. The locking mechanism is connected to the push rod 24 and the support frame respectively.

[0029] The locking mechanism includes a fixed plate 31, a positioning block 32, and a sliding block 33. The fixed plate 31 is fixedly connected to the support frame. The positioning block 32 is slidably connected to the push rod 24. A locking block 34 is fixedly connected to the fixed plate 31. The positioning block 32 has a locking groove 35 that mates with the locking block 34. The positioning block 32 is fixedly connected to the sliding block 33. The push rod 24 has a sliding groove 25, and the sliding block 33 is slidably connected to the sliding groove 25. A drive rod 41 is slidably connected inside the push rod 24. The sliding block 33 is fixedly connected to the drive rod 41. The drive rod 41 extends from the end of the push rod 24 away from the rotating sleeve 22. A retaining ring 42 is fixedly connected to the drive rod 41. An elastic element is provided between the retaining ring 42 and the push rod 24. The elastic element is a spring 43 with both ends abutting against the retaining ring 42 and the push rod 24, respectively. Multiple locking blocks 34 are provided, and the multiple locking blocks 34 are evenly distributed around the rotation axis of the rotating sleeve 22.

[0030] This embodiment has the following advantages:

[0031] Place the ladder on the support frame and push the push rod 24 by hand. This causes the rotating sleeve 22 and the buckle plate 23 to rotate on the connecting rod 13, pressing the ladder against the support frame. The buckle plate 23 and the support frame respectively hold the ladder in place on the top and bottom sides. The end of the buckle plate 23 away from the rotating sleeve 22 bends towards the support frame. Therefore, when the buckle plate 23 is pressing down on the ladder, this end can insert into the inside of the ladder, thus securing the ladder from the inside and preventing it from slipping off the support frame. This achieves the advantage of greater stability for the ladder on the shelf.

[0032] After the end of the buckle plate 23 away from the rotating sleeve 22 is inserted into the inside of the ladder, it drives the sliding block 33 to move in the slide groove 25. The sliding block 33 drives the positioning block 32 and the slot 35 to move, so that the slot 35 moves towards the locking block 34, thereby locking the slot 35 and the locking block 34, realizing the locking of the push rod 24, the rotating sleeve 22 and the buckle plate 23, so that the end of the buckle plate 23 away from the rotating sleeve 22 is kept inserted into the inside of the ladder, preventing the ladder from accidentally slipping off the support frame.

[0033] Pressing on the push rod 24 pushes the drive rod 41 to move, causing the drive rod 41 to drive the sliding block 33 to move within the slide groove 25, thus facilitating the movement of the sliding block 33.

[0034] The elastic element can provide elastic force on the retaining ring 42, pushing the retaining ring 42 and the drive rod 41 to move the sliding block 33 and the positioning block 32, so that the positioning block 32 and the slot 35 tend to move towards the locking block 34, keeping the slot 35 and the locking block 34 engaged, preventing the slot 35 and the locking block 34 from accidentally disengaging, and ensuring the stability and reliability of the locking mechanism.

[0035] When the drive rod 41 is pressed, it can compress the spring 43, causing the drive rod 41 to move the sliding block 33 and the positioning block 32. When the drive rod 41 is released, the spring 43 can provide elastic force on the retaining ring 42 to push the retaining ring 42 and the drive rod 41 to move the sliding block 33 and the positioning block 32, achieving the effect of engaging the retaining groove 35 with the retaining block 34 through the elastic element.

[0036] Two clamping components 21 can hold the ladder in different positions, further preventing the ladder from slipping off the support frame. By pressing the synchronous pressure rod 44, the two drive rods 41 are simultaneously pushed to move, which facilitates the movement of the two drive rods 41.

[0037] When the two clamping components 21 clamp the ladder from above, the inner beam 12 between the two clamping components 21 provides support to the ladder from below, so that the ladder is balanced by force and supports the stability of the ladder on the support frame.

[0038] Multiple dedicated shelves for the ladder are arranged vertically, and the uprights 14 of the dedicated shelves for the lower ladder are inserted into the connecting slots 16 of the dedicated shelves for the upper ladder. This allows the dedicated shelves for the ladder to be arranged vertically, effectively utilizing vertical space and facilitating the storage of ladder components.

[0039] Multiple locking blocks 34 can engage with the slots 35 at different angles, thereby locking the buckle 23 at different angles.

[0040] Based on the disclosure and teachings of the above specification, those skilled in the art can make changes and modifications to the above embodiments. Therefore, this utility model is not limited to the specific embodiments disclosed and described above, and some modifications and changes to the utility model should also fall within the protection scope of the claims of this utility model. Furthermore, although some specific terms are used in this specification, these terms are only for convenience of explanation and do not constitute any limitation on the utility model.
