Abstract
Description
Technical Field
[0001] This utility model relates to the field of diamond wire changing wheel transportation technology, and more specifically, it relates to a diamond wire changing wheel handcart. Background Technology
[0002] In silicon wafer processing companies within the photovoltaic industry, the number of cutting machines is typically large, and the replacement frequency of diamond wire reels is also high. Currently, many companies still rely on employees manually handling the diamond wire reels and placing them one by one next to the machines. However, diamond wire is extremely sensitive to external force damage and water-based substances. In the past, employees often carelessly placed the diamond wire next to the machines after handling it, making the wire susceptible to impact damage. Furthermore, water splashed during machine cleaning may also come into contact with the diamond wire, affecting its quality. These problems not only increase production costs but may also reduce production efficiency and product quality. Chinese patent document CN211196313U discloses a diamond wire changing wheel trolley. By setting up a movable trolley, and setting up structures such as protrusions and positioning blocks on the base of the trolley for fixing diamond wire changing wheels, multiple wheels can be stored and transported at the same time. Old wheels can be replaced and placed without affecting the workshop layout. Employees can pick them up and put them down at any time. When encountering cleaning equipment, they can be moved to a safe area at any time.
[0003] However, the aforementioned solution only uses a simple placement structure such as a single layer of protrusions on the base, resulting in a very limited number of diamond wire reels that can be stored. While this design solves the storage problem to some extent, the low space utilization forces employees to frequently travel between the storage area and the equipment when changing diamond wire reels, increasing operational steps and time costs. Frequent handling not only reduces work efficiency but may also lead to employee fatigue and even increase the risk of damage to the reels due to repeated movements. Furthermore, the limited storage space restricts the overall management efficiency of wire reels in the workshop, making it difficult to meet the needs of large-scale production. Utility Model Content
[0004] (a) Technical problems to be solved To address the problems existing in the prior art, this utility model provides a diamond wire changing wheel trolley to solve the technical problem mentioned in the background art that the existing diamond wire changing wheel trolley has a small number of wire wheels that can be stored and low efficiency.
[0005] (II) Technical Solution To achieve the above objectives, this utility model provides the following technical solution: A diamond wire changing wheel trolley includes a base with a movable wheel at the bottom. Multiple mounting brackets are mounted on top of the base, and a support leg is foldably mounted between two adjacent mounting brackets. Mounting plates are slidably mounted on the mounting brackets, and each mounting plate has a mounting post with a threaded positioning block. A push-pull handle is vertically movable at the rear end of the base. The positioning blocks can be replaced according to the diameter of different diamond wire changing wheels, thereby securing different diamond wire changing wheels.
[0006] The present invention is further configured such that the mounting frame is provided with a mounting groove, and the two sides of the mounting plate are provided with mounting strips. The mounting strips are slidably located in the mounting groove. The mounting plate can slide on the mounting frame through the cooperation of the mounting strips and the mounting groove, so that the mounting plate can be pulled outward on the mounting frame.
[0007] The present invention is further configured such that the push-pull handle includes a fixed column, a lifting column is provided on the fixed column, and a push-pull rod is provided at the top of the lifting column.
[0008] The present invention is further configured such that a lifting groove is provided on the fixed column, the bottom end of the lifting column is slidably located in the lifting groove, and a locking member is threaded on the side wall of the fixed column. The inner end of the locking member abuts against the side wall of the lifting column. The lifting groove allows the lifting column to be adjusted in height within the groove, thereby adjusting the lifting of the push-pull rod. In this way, when not in use, the lifting column can be lowered and stored along with the push-pull rod, reducing the overall footprint. When in use, the lifting column raises the push-pull rod, thereby increasing the height of the push-pull handle and improving ease of use. At this time, tightening the locking member can lock the lifting column onto the fixed column.
[0009] The present invention is further configured such that the support leg includes an upper support column and a lower support column, the upper support column and the lower support column are foldable and connected, and are equipped with a limit locking structure.
[0010] The present invention is further configured such that a first hinge is provided between the inner top end of the upper support column and the upper mounting frame, a second hinge is provided between the inner bottom end of the lower support column and the lower mounting frame, and a third hinge is provided on the outer side of the connection between the upper and lower support columns. The cooperation of the first and second hinges allows the upper and lower support columns to be flipped inward relative to the mounting frame, and the relative folding between the upper and lower support columns is achieved through the third hinge. In this way, the folding and unfolding of the support legs can be realized.
[0011] The present invention is further configured such that the limiting and locking structure includes a fixing block, the fixing block is disposed on the outer side of the upper support column, a limiting post is slidably disposed on the fixing block, a limiting block is disposed on the lower support leg, and a limiting groove is formed on the limiting block and the limiting post. By controlling the limiting post on the fixing block to move downward, the bottom end of the limiting post is engaged and inserted into the limiting groove on the lower limiting block, thereby restricting the mutual rotation between the upper and lower support columns, realizing the stable deployment of the support leg, and providing stable support for the mounting frame.
[0012] The present invention is further configured such that the top end of the upper support column and the bottom end of the lower support column are provided with engaging protrusions, and the top end and the bottom end of the mounting frame are provided with engaging grooves. The engaging protrusions are engaged and fixed in the corresponding engaging grooves. When the upper support column is unfolded, the corresponding engaging protrusions engage into the corresponding engaging grooves, thereby improving the connection stability between the upper support column and the lower support column and the mounting frame when the whole is moved.
[0013] (III) Beneficial Effects Compared with the prior art, this utility model provides a diamond wire changing wheel handcart, which has the following beneficial effects: 1. In this utility model, a multi-layer mounting frame is provided on the base, and a mounting plate is provided on each layer of the mounting frame. The diamond wire changing wheel is stably placed on the mounting plate by the mounting columns and positioning blocks on the mounting plate. In this way, the number of diamond wire changing wheels can be placed, improving space utilization and ease of use.
[0014] 2. In addition, in this utility model, the mounting plate is slidably mounted on the mounting frame through the cooperation of the mounting groove and the mounting strip. In this way, when installing and removing the diamond wire changing wheel, the mounting plate can be pulled outward, so that the diamond wire changing wheel located on the mounting plate can be picked up and placed more conveniently.
[0015] 3. This utility model uses support legs to support the upper and lower sets of mounting frames. The support legs include an upper support column and a lower support column that can be folded and engaged with each other. In use, the upper and lower support columns are unfolded, and the limiting column on the fixing block is moved downwards, causing the bottom end of the limiting column to engage with the limiting groove on the lower limiting block. This restricts the mutual rotation between the upper and lower support columns, ensuring stable unfolding of the support legs and providing stable support for the mounting frame. When not in use, the limiting column can be removed from the limiting groove, allowing the upper and lower support columns to fold inwards, thus folding and storing the support legs and reducing the overall footprint when not in use.

[0021] Please see Figures 1-5A diamond wire changing wheel trolley includes a base 1, with a movable wheel 2 at the bottom of the base 1, and multiple mounting brackets 3 on the top of the base 1. A support leg 4 is foldably provided between two adjacent mounting brackets 3. Mounting plates 5 are slidably mounted on the mounting brackets 3, and each mounting plate 5 is provided with a mounting post 6. Each mounting post 6 is threaded with a positioning block 7. A push-pull handle 8 is provided at the rear end of the base 1. The positioning block 7 can be replaced according to the diameter of different diamond wire changing wheels, thereby fixing different diamond wire changing wheels.
[0022] Please see Figures 1-5 As one embodiment of the mounting bracket 3: the mounting bracket 3 is provided with a mounting groove 9, and mounting strips 10 are provided on both sides of the mounting plate 5. The mounting strips 10 slide within the mounting groove 9. Through the cooperation of the mounting strips 10 and the mounting groove 9, the mounting plate 5 can slide on the mounting bracket 3, so that the mounting plate 5 can be pulled outward on the mounting bracket 3.
[0023] Please see Figures 1-5 As one embodiment of the push-pull handle 8: The push-pull handle 8 includes a fixed column 11, a lifting column 12 is provided on the fixed column 11, and a push-pull rod 13 is provided at the top of the lifting column 12.
[0024] Specifically, this utility model has a lifting groove 14 on the fixed column 11. The bottom end of the lifting column 12 slides within the lifting groove 14. A locking member 15 is threaded on the side wall of the fixed column 11. The inner end of the locking member 15 presses against the side wall of the lifting column 12. The lifting groove 14 allows the lifting column 12 to be adjusted in height within the groove, thereby adjusting the lifting rod 13. When not in use, the lifting column 12 can be lowered and stored with the pushing rod 13, reducing the overall footprint. When in use, the lifting column 12 raises the pushing rod 13, increasing the height of the push handle 8 and improving ease of use. At this time, tightening the locking member 15 locks the lifting column 12 onto the fixed column 11.
[0025] Please see Figures 1-5 As one embodiment of the support leg 4: the support leg 4 includes an upper support column 16 and a lower support column 17, the upper support column 16 and the lower support column 17 are foldable and connected, and are equipped with a limit locking structure.
[0026] Specifically, this utility model has a first hinge 18 between the inner top of the upper support column 16 and the upper mounting frame 3, a second hinge 19 between the inner bottom of the lower support column 17 and the lower mounting frame 3, and a third hinge 20 on the outer side of the connection between the upper support column 16 and the lower support column 17. The cooperation of the first hinge 18 and the second hinge 19 allows the upper support column 16 and the lower support column 17 to flip inward relative to the mounting frame 3. The third hinge 20 enables the relative folding between the upper support column 16 and the lower support column 17. In this way, the folding and unfolding of the support leg 4 can be achieved.
[0027] Furthermore, the limiting and locking structure includes a fixing block 21, which is located on the outer side of the upper support column 16. A limiting post 22 is slidably mounted on the fixing block 21, and a limiting block 23 is mounted on the lower support column 17. A limiting groove 24 is formed on the limiting block 23 in conjunction with the limiting post 22. By controlling the limiting post 22 on the fixing block 21 to move downward, the bottom end of the limiting post 22 is engaged and inserted into the limiting groove 24 on the lower limiting block 23. This restricts the mutual rotation between the upper support column 16 and the lower support column 17, thereby achieving stable deployment of the support leg 4 and providing stable support for the mounting frame 3.
[0028] More specifically, this utility model provides engaging protrusions 25 at the top of the upper support column 16 and the bottom of the lower support column 17, and engaging grooves 26 at the top and bottom of the mounting frame 3. The engaging protrusions 25 are engaged and fixed in the corresponding engaging grooves 26. When the upper support column 16 is unfolded, the corresponding engaging protrusions 25 engage into the corresponding engaging grooves 26, thereby improving the connection stability between the upper support column 16 and the lower support column 17 and the mounting frame 3 when the whole is moved.
[0029] In summary: In this utility model, a multi-layer mounting frame 3 is provided on the base 1, and a mounting plate 5 is provided on each layer of mounting frame 3. The diamond wire changing wheel is stably placed on the mounting plate 5 by the mounting column 6 and positioning block 7 on the mounting plate 5. In this way, the number of diamond wire changing wheels can be effectively increased, the space utilization rate and the ease of use can be improved. Meanwhile, in this utility model, the mounting plate 5 is slidably mounted on the mounting frame 3 through the cooperation of the mounting groove 9 and the mounting strip 10. In this way, when installing and removing the diamond wire changing wheel, the mounting plate 5 can be pulled outward, so that the diamond wire changing wheel located on the mounting plate 5 can be picked up and placed more conveniently. This invention uses support legs 4 to support the upper and lower sets of mounting frames 3. The support legs 4 include an upper support column 16 and a lower support column 17 that can be folded together. In use, the upper support column 16 and lower support column 17 are unfolded, and the limiting column 22 on the fixing block 21 is moved downwards, causing the bottom end of the limiting column 22 to engage and extend into the limiting groove 24 on the lower limiting block 23. This restricts the mutual rotation between the upper support column 16 and lower support column 17, achieving stable unfolding of the support legs 4 and providing stable support for the mounting frame 3. When not in use, the limiting column 22 can be removed from the limiting groove 24, allowing the upper support column 16 and lower support column 17 to fold inwards, thus folding and storing the support legs 4, reducing the overall footprint when not in use.
