Description

Technical Field

[0001] This utility model relates to metallurgical production, and in particular to a powder metallurgy product transfer trolley. Background Technology

[0002] Metallurgical production is a technology that manufactures metal products by mixing, pressing, and sintering metal or non-metal powders. During the powder metallurgy process, intermediate products such as steel billets and products that need to be ground may be generated. These intermediate products generally need to be transferred to the next production stage for further processing. Current technology generally uses powder metallurgy product transfer carts for transfer.

[0003] Intermediate products produced by powder metallurgy generally have high temperatures. When placed on transfer trolleys, attention should be paid to ventilation to avoid heat accumulation. Typical transfer trolleys use plate-type shelves, and the intermediate powder metallurgy products are placed on these shelves. This results in a large contact area between the transfer trolley and the intermediate powder metallurgy products, making it easy for heat to accumulate on the shelves. At the same time, the larger the contact area between the transfer trolley and the intermediate powder metallurgy products, the lower the heat dissipation efficiency of the intermediate powder metallurgy products.

Detailed Implementation

[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0030] Example 1: This example aims to propose a powder metallurgy product transfer trolley;

[0031] according to Figures 1 to 4 As shown, it includes a base plate 1 and a support rod 2.

[0032] The base plate 1 includes two horizontal plates 101. In this embodiment, the horizontal plates 101 can be made of flat steel. The horizontal plates 101 extend in the front-to-back direction. The upper surface of the horizontal plates 101 is provided with two lower connecting frames 103 that are positioned front-to-back. A supporting beam 104 is provided below the lower connecting frames 103. Both the left and right ends of the supporting beam 104 extend to be flush with the outer side of the horizontal plate 101 on the same side. Bolts are provided on the lower connecting frames 103. The lower ends of the bolts pass through the lower surface of the horizontal plates 101 and are detachably connected to the supporting beam 104 below. The lower surface of the horizontal plates 101 abuts against the supporting beam 104. The supporting beam 104 is provided with rollers that are positioned left-to-right.

[0033] A support plate 102 is provided between the two horizontal plates 101, and the lower surface of the support plate 102 abuts against the support beam 104.

[0034] The support rod 2 extends vertically and is mounted on the base plate 1. The lower connecting frame 103 is an L-shaped structure extending left and right. In this embodiment, the lower connecting frame 103 can be made of angle steel. The upward extension of the lower connecting frame 103 is detachably connected to the support rod 2 by bolts. The lower surface of the support rod 2 contacts the upper surface of the horizontal plate 101. The lower connecting frame 103 extends laterally to the top of the support plate 102 and presses the support plate 102 onto the support beam 104.

[0035] Multiple auxiliary support rods 3 are provided between adjacent support rods 2. In this embodiment, support rods 2 and auxiliary support rods 3 can be made of flat steel. The auxiliary support rods 3 are vertically arranged on the upper surface of the base plate 1. The auxiliary support rods 3 are arranged at intervals in the front-back direction. The auxiliary support rods 3 are fixedly connected to the horizontal plate 101. The lower end of the auxiliary support rods 3 is welded to the upper surface of the horizontal plate 101.

[0036] Multiple first shelves 8 are provided between the two auxiliary support rods 3 corresponding to the left and right positions. The multiple first shelves 8 are arranged at intervals in the vertical direction. Each first shelf 8 includes two U-shaped clamps. In this embodiment, the U-shaped clamps can be made of round steel, which is bent into a U-shape. The U-shaped clamps are set horizontally, and both ends of the U-shaped clamps are fixedly connected to the outer surface of the auxiliary support rod 3 on the same side. The opening directions of the two U-shaped clamps corresponding to the front and rear positions are opposite, and the two U-shaped clamps form a ring support structure.

[0037] Multiple second shelves 9 are provided between the two corresponding support rods 2, and the second shelves 9 are fixedly connected to the side of the support rod 2 near the auxiliary support rod 3. The second shelves 9 have a semi-circular structure, and multiple second shelves 9 are arranged at intervals in the vertical direction. The second shelves 9 include a U-shaped clamp, and the left and right ends of the U-shaped clamp are fixedly connected to the outer surface of the support rod 2 on the same side.

[0038] The base plate 1 is provided with multiple vertically arranged connecting rods 6. The connecting rods 6 can be made of flat steel. The connecting rods 6 are fixedly connected to the support plate 102. The connecting rods 6 are arranged at intervals in the front-back direction, and the support rods 2 and auxiliary support rods 3 are all laterally corresponding to the adjacent connecting rods 6. The middle end of the U-shaped clamp is fixedly connected to a support rod 7 extending in the front-back direction. The end of the support rod 7 near the adjacent connecting rod 6 is fixedly connected to the outer surface of the connecting rod 6.

[0039] The working principle of this embodiment is as follows: Two support beams 104 of equal width are selected and placed one in front of the other. Then, two horizontal plates 101 are placed on the support beams 104, corresponding to each other. At the same time, a support plate 102 is placed in the gap between the horizontal plates 101. Then, insertion holes are made on the horizontal plates 101, and threaded locking holes are made on the support beams 104. Then, the lower connecting frame 103 is placed on the horizontal plate 101, and bolts are inserted into the lower connecting frame 103. The lower end of the bolt passes through the insertion hole and extends into the threaded locking hole on the support beam 104 and is threadedly connected. Through the above method, all the lower connecting frames 103 and support beams 104 are connected to the horizontal plates 101.

[0040] Then, the support rod 2 is vertically set on the horizontal plate 101, and then the support rod 2 is connected to the lower connecting frame 103 by bolts.

[0041] Next, auxiliary support rod 3 is welded to horizontal plate 101, connecting support rod 6 is welded to support plate 102, and then a fixed length of round steel is bent into U-shaped clamps, which are then welded to auxiliary support rod 3 or support rod 2 at intervals. The front and rear sides of auxiliary support rod 3 are welded to the U-shaped clamps.

[0042] When in use, the intermediate powder metallurgy product is placed on the ring support structure formed by two U-shaped clamps. When the intermediate product is long, one end of the intermediate product can be placed on the second shelf 9 on the support rod 2, and the other end of the intermediate product can be placed on the first shelf 8 corresponding to the position of the second shelf 9. At the same time, when the intermediate product to be transported is high, the number and spacing of the U-shaped clamps can be selected according to the usage. Only one first shelf 8 can be set between the two auxiliary support rods 3 corresponding to the left and right positions, so that the space above the first shelf 8 can be used to place the intermediate product, avoiding the impact of multiple first shelves 8 on the utilization of space.

[0043] Therefore, the number and location of the first shelf 8 and the second shelf 9 can be selected according to the usage scenario. At the same time, the whole can be quickly assembled. Both the first shelf 8 and the second shelf 9 use a U-shaped clamp structure, which minimizes the contact area between the items placed in the middle and the product. In addition, there are large gaps between the first shelf 8 and the second shelf 9, which facilitates air flow and ventilation. Heat is not easily accumulated in the first shelf 8 and the second shelf 9, thus avoiding heat accumulation and thermal fatigue.

[0044] Example 2:

[0045] according to Figure 1 As shown, an upper connecting frame 201 is bolted to the support rod 2. In this embodiment, the upper connecting frame 201 can be made of angle steel. The upper connecting frame 201 is an L-shaped structure with the opening facing downward. The downward extension of the upper connecting frame 201 is detachably connected to the upper end of the outer surface of the support rod 2. A top plate 4 is provided between the upper surfaces of the upper connecting frame 201.

[0046] The lower surface of the top plate 4 is detachably connected to the upper surface of the upper connecting frame 201. Bolts are inserted into the top plate 4, and the lower ends of the bolts are threaded to the upper connecting frame 201. Bolt sockets corresponding to the upper and lower positions of the upper connecting frame 201 are opened on the top plate 4. Bolts are inserted into the bolt sockets, and the lower ends of the bolts are threaded to the upper connecting frame 201. The top plate 4 can be quickly installed onto the support rod 2. The upper end of the auxiliary support rod 3 is fixedly connected to the lower surface of the top plate 4. The upper end of the connecting support rod 6 is fixedly connected to the lower surface of the top plate 4. The top plate 4 is provided with a handle 5. The rest of the structure is the same as in embodiment 1.

[0047] The working principle of this embodiment is as follows: the upper connecting frame 201 is installed to the support rod 2 with bolts, and then the top plate 4 is placed between the upper surfaces of the upper connecting frame 201. The top plate 4 is connected to the upper connecting frame 201 with bolts, thereby quickly installing the top plate 4 onto the support rod 2.

[0048] This allows for the rapid installation of the top plate (4), while preventing hot air from flowing upwards when the temperature is high, and also preventing workers pushing the trolley from coming into contact with powder metallurgy intermediate products, thus avoiding injury to personnel, and improving the overall stability of the device.

[0049] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims and not by the foregoing description. Thus, all variations falling within the meaning and scope of equivalents of the claims are intended to be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
