Description

Technical Field

[0001] This utility model relates to the field of casting production technology, specifically to a stacking device for castings in mining machinery. Background Technology

[0002] The production process of castings for mining machinery typically begins with raw material smelting. Metal raw materials are heated to a molten state in a furnace, and after composition adjustment, they are poured into a mold cavity. The molten metal cools and solidifies to form a casting blank. The blank needs to be cleaned of sand and ground to remove surface burrs and excess risers. It then undergoes flaw detection to check for internal defects. Qualified blanks are then machined for dimensional finishing, and finally, surface treatment improves corrosion resistance. Between these stages, the castings need to be stacked and transferred multiple times, for example, from temporary storage racks in the casting area to the grinding station, and from the inspection area to the machining workshop, to ensure a continuous and efficient production process. In the existing technology, castings are mostly stacked and transported by feeding trolleys, but there are obvious drawbacks: the trolley shelves generally do not have roller devices, and a lot of traction force is required when gradually pushing and pulling the castings in and out of the trolley. This is especially inconvenient when large castings are stacked, and it is also very laborious to adjust the posture of the castings during the stacking process. Utility Model Content

[0003] In view of the above situation and to overcome the defects of the prior art, the purpose of this utility model is to provide a stacking device for mining machinery castings, so as to at least partially solve the problems mentioned in the background art.

[0004] Therefore, the purpose of this utility model is to provide a stacking device for mining machinery castings, which reduces the pushing and pulling force during the stacking process and ensures stable transportation after stacking.

[0005] To achieve the above objectives, this utility model proposes a stacking device for castings of mining machinery, comprising a support frame and a rolling lifting assembly. The rolling lifting assembly is located at the bottom of the support frame and includes a roller bracket, a bracket adjusting rod, and a roller. The roller bracket is located below the support frame, and the roller is rotatably mounted on the roller bracket. The bracket adjusting rod is telescopically mounted between the support frame and the roller frame. Multiple support plates are provided on the inner side of the support frame, with one roller corresponding to every two support plates.

[0006] Furthermore, a railing assembly is provided on the inner side of the support frame, including a side railing, a rear railing, and a support block. The support block is disposed on the inner wall of the support frame, and the side railing and the rear railing are secured to the support block. The side railing is located on both sides of the support frame, and the rear railing is located on the rear side of the support frame.

[0007] Furthermore, the feeding end of the support frame is provided with a feeding assembly, including a feeding plate and a feeding roller. The feeding plate is hinged to the feeding end of the support frame by a spring hinge, and the feeding roller is disposed between the feeding plate and the support plate. The height of the feeding roller is higher than the height of the support plate.

[0008] Furthermore, the side panel is provided with an L-shaped locking rod, the end of which is provided with a locking head, and the bottom of the feed plate is provided with a locking rod slot that is compatible with the locking head.

[0009] Furthermore, the bottom of the support frame is provided with foot supports, and the feeding end of the support frame is provided with a feeding plate limiting rod.

[0010] Furthermore, the bracket adjusting rod is one of a lead screw, a hydraulic rod, or an electric push rod.

[0011] Beneficial effects: This utility model sets multiple support plates inside the support frame and sets a vertically movable roller between adjacent support plates. During the pushing and pulling process of casting stacking, the roller frame and roller are lifted upward together by the bracket adjusting rod. The roller enters between adjacent support plates. At this time, the top of the roller is higher than the support plate. The bottom of the casting is supported by the roller, which facilitates the transfer of castings and reduces the pushing and pulling traction force during the casting stacking process. During transportation, the roller moves downward. At this time, the bottom of the casting is supported by the support plate, making the casting transfer process more stable.

[0015] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this utility model, and should not be construed as limiting this utility model.

[0016] The following description, in conjunction with the accompanying drawings, describes a mining machinery casting stacking device according to an embodiment of the present invention.

[0017] like Figures 1-3 As shown in the figure, the mining machinery casting stacking device provided in this embodiment of the utility model includes a support frame 2 and a rolling lifting assembly 3. The rolling lifting assembly 3 is located at the bottom of the support frame 2 and includes a roller bracket 31, a bracket adjusting rod 32 and a roller 33. The roller bracket 31 is located below the support frame 2, and the roller 33 is rotatably mounted on the roller bracket 31. The bracket adjusting rod 32 is telescopically mounted between the support frame 2 and the roller 33 frame. The bracket adjusting rod 32 is one of a screw rod, a hydraulic rod or an electric push rod. Multiple support plates 22 are provided on the inner side of the support frame 2, and a roller 33 is located below every two support plates 22.

[0018] Specifically, when the casting stacking device of this application is in use, if the casting needs to be pushed or pulled into or out of the inner side of the support frame 2, the roller 33 frame and the roller 33 are lifted upward together by the bracket adjusting rod 32. The roller 33 enters between the adjacent support plates 22. At this time, the top of the roller 33 is higher than the position of the support plate 22. The bottom of the casting is supported by the roller 33, which facilitates the transfer of the casting and reduces the pushing and pulling force during the stacking process. When the device carries the casting for transportation, the roller 33 moves downward and the casting is separated from the roller 33. At this time, the bottom of the casting is supported by the support plate 22, making the casting transfer process more stable.

[0019] In one embodiment of this utility model, such as Figure 1As shown, a railing assembly 1 is provided on the inner side of the support frame 2, including a side railing 13, a rear railing 15 and a support block 14. The support block 14 is provided on the inner wall of the support frame 2. The side railing 13 and the rear railing 15 are snapped onto the support block 14 to facilitate the installation of the side railing 13 and the rear railing 15. The side railing 13 is located on both sides of the support frame 2, and the rear railing 15 is located on the rear side of the support frame 2.

[0020] Specifically, in order to prevent the castings from detaching from the support frame 2 during transportation after being stacked, side rails 13 and rear rails 15 are installed on the support frame 2 to laterally enclose the castings inside the support frame 2 and prevent the castings from falling out of the support frame 2.

[0021] In one embodiment of this utility model, such as Figures 1-3 As shown, the feeding end of the support frame 2 is provided with a feeding assembly 4, including a feeding plate 42 and a feeding roller 41. The feeding plate 42 is hinged to the feeding end of the support frame 2 by a spring hinge 45. The feeding roller 41 is disposed between the feeding plate 42 and the support plate 22, and the height of the feeding roller 41 is higher than the height of the support plate 22.

[0022] An L-shaped locking rod 11 is provided on the side panel 13, and a locking head 12 is provided at the end of the L-shaped locking rod 11. A locking rod slot 43 that is compatible with the locking head 12 is provided at the bottom of the feed plate 42. A foot support 21 is provided at the bottom of the support frame 2, and a feed plate limiting support rod 44 is provided at the feed end of the support frame 2.

[0023] Specifically, when the feed plate 42 is in a horizontal state, the feed plate 42 is in contact with the limiting rod under the elastic action of the spring hinge 45, so that the feed plate 42 can stably feed the material. In addition, after the casting product is fed from the feed plate 42 into the feed roller 41, it enters the support plate 22 through the feed roller 41. Since the height of the feed roller 41 is higher than the height of the support plate 22, it can prevent the casting from returning to the feed plate 42, which plays a role in blocking the casting. When the feeding is completed, the feed plate 42 is vertically flipped to push the L-shaped locking rod 11. The clip 12 at the end of the L-shaped locking rod 11 is engaged into the locking rod slot 43 on the back of the feed plate 42. The feed plate 42 is tightly fitted with the L-shaped locking rod 11 under the elastic action of the spring hinge 45. At this time, the feed plate 42, the side rail plate 13 and the rear rail plate 15 form a rectangular fence structure to block the casting products inside the support frame 2.

[0024] To clearly illustrate the above embodiments, refer to Figures 1-3The specific working principle of the mining machinery casting stacking device of this utility model is as follows: When the casting needs to be pushed or pulled into or out of the inner side of the support frame 2, the bracket adjusting rod 32 retracts, driving the roller 33 frame and roller 33 to move upward and approach the support plate 22 together. The roller 33 enters between the adjacent support plates 22. At this time, the top of the roller 33 is higher than the position of the support plate 22. The bottom of the casting is supported by the roller 33, which facilitates the transfer of the casting and reduces the pushing and pulling force during the stacking process.

[0025] When the device is transporting castings together, the bracket adjusting rod 32 extends and drives the roller 33 frame and roller 33 downward away from the support plate 22, and the castings separate from the roller 33. At this time, the bottom of the castings is supported by the support plate 22, making the casting transfer process more stable and preventing shaking during transportation.

[0026] In addition, after feeding is completed, the feeding plate 42 is flipped vertically and the L-shaped locking rod 11 is pushed. The clip 12 at the end of the L-shaped locking rod 11 is inserted into the locking rod slot 43 on the back of the feeding plate 42. At this time, the feeding plate 42, the side railing 13 and the rear railing 15 form a rectangular fence structure to surround the casting products inside the support frame 2, so that the castings can be transported stably after being stacked.

[0027] Although embodiments of the present invention have been shown and described above, it is understood that the above embodiments are exemplary and should not be construed as limiting the present invention. Those skilled in the art can make changes, modifications, substitutions and variations to the above embodiments within the scope of the present invention.
