Description

Technical Field

[0001] This utility model relates to the field of chain conveyor technology, specifically to a conveyor head and tail frame and a conveyor frame. Background Technology

[0002] In the prior published document "Publication No.: CN11410464A, entitled: A high-speed heavy-duty chain plate conveyor", the head and tail frames of the conveyor are made of steel plates that are cut and then welded with bent ears to form supporting side plates, which are then connected by connectors. The vertical load-bearing capacity is mainly provided by the supporting side plates of the head and tail frames. In order to further reduce the amount of consumables used in the production of the equipment, a solution is urgently needed. Utility Model Content

[0003] To address the shortcomings of existing technologies, this utility model provides a conveyor head and tail frame and a conveyor frame.

[0004] A conveyor head and tail frame includes two supporting side plates, which are detachably connected by a connector.

[0005] The edges of the supporting side plate are set at an included angle and / or at a rounded corner. A cutting groove is formed at the included angle of the edges, and the two sides of the cutting groove are perpendicular to the corresponding two edges. A bending groove is formed at the included angle of the edges, and the depth of the bending groove is less than the length of the side of the cutting groove.

[0006] The edge of the support side plate is offset to coincide with the angle along the cutting groove to form a bending area, and the bending area is bent to form a number of mutually separated bent ears.

[0007] Furthermore, the inner side of the support side plate near the bending area is stamped with reinforcing ribs.

[0008] Furthermore, one side of the supporting side plate is arranged in a "Z" shape.

[0009] Furthermore, it also includes several reinforcing members that can be installed between the bent ears.

[0010] Furthermore, the connector includes several connecting rods and two connecting angle steels, both of which are installed between the two supporting side plates;

[0011] The two connecting angle steels are installed between the two sides of the bottom of the two supporting side plates, and partially extend out of the two supporting side plates to form a reinforcing member.

[0012] A conveyor frame, further comprising an extension frame installed between the head and tail frames of the conveyor;

[0013] The outer sides of both ends of the extended frame are vertically fixed with mounting ears, and the bent ears on the straight edge of the support side plate are adapted to the mounting ears to form a mounting part.

[0014] It also includes a reinforcing angle steel, one side of which is detachably connected to the mounting part to enhance the strength of the mounting part.

[0015] Furthermore, the other side of the reinforcing angle steel that is not connected to the mounting part is set perpendicular to the supporting side plate;

[0016] The surface of the support side plate near the mounting part has an insertion hole. A connecting rod is inserted through both support side plates and protrudes from the support side plate to form a force-bearing part. The other side of the reinforcing angle steel that is not connected to the mounting part is detachably connected to the force-bearing part.

[0017] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0018] The cutting groove of this utility model can prevent the bending ears at the straight edges of the support side plate from interfering with each other. The bending groove is opened at the corner of the rounded edge, which can reduce the width of the bending ears corresponding to the rounded corner area, so that the bending ears can be bent and shaped, thereby strengthening the vertical support strength of the support side plate. From the perspective of equipment processing, a large number of welding processes are eliminated, which can significantly reduce production costs. Attached Figure Description

[0030] Example 1:

[0031] Please see Figures 1-3 A conveyor head and tail frame includes two supporting side plates 3, which are detachably connected by a connector 4.

[0032] The edges of the supporting side plate 3 are set at an angle and / or at a rounded corner. A cutting groove 32 is provided at the angle of the edge. The two sides of the cutting groove 32 are perpendicular to the corresponding two edges. A bending groove 33 is provided at the angle of the edge. The depth of the bending groove 33 is less than the length of the side of the cutting groove 32.

[0033] The edge of the supporting side plate 3 is offset to coincide with the angle along the cutting groove 32 to form a bending area 31, and the bending area 31 is bent to form a number of mutually separated bending ears 34.

[0034] The inner side of the support side plate 3 near the bending area 31 is stamped with reinforcing ribs 36.

[0035] One side of the support side plate 3 is arranged in a "Z" shape, and all the edges and corners on this side are rounded.

[0036] It also includes several reinforcing members 10, which can be installed between the bent ears 34 to strengthen the bent ears 34.

[0037] The connector 4 includes several connecting rods 41 and two connecting angle steels 42, and the connecting rods 41 and the connecting angle steels 42 are installed between the two supporting side plates 3;

[0038] Two connecting angle steels 42 are installed between the two sides of the bottom of the two supporting side plates 3, and partially extend out of the two supporting side plates 3 to form a reinforcing member 10. This serves to connect the two supporting side plates 3 and also to connect and reinforce the adjacent bent ears 34 in the supporting side plates 3.

[0039] The cutting groove 32 can prevent the bending ears 34 at the straight edges of the supporting side plate 3 from interfering with each other. The bending groove 33 is provided at the corner of the rounded edge, which can reduce the width of the bending ears 34 corresponding to the rounded corner area, so that the bending ears 34 can be bent and shaped, thereby strengthening the vertical support strength of the supporting side plate 3.

[0040] All detachable connections can be made using bolts.

[0041] Please see Figure 3 A method for producing conveyor head and tail frames, used to produce the aforementioned conveyor head and tail frame 1, includes the following steps:

[0042] S1. Set the top and bottom of the steel plate with a thickness of not less than 4mm symmetrically as cutting endpoints along the origin, and set a “Z” shaped dividing line 35 between the two cutting endpoints. Cut the rectangular plate along the “Z” shaped dividing line 35 into equivalent supporting side plates 3.

[0043] S2. A bending area 31 with a width of 30mm to 60mm is formed by offsetting inward along the edge of the support side plate 3. A cutting groove 32 is opened at the included angle of the straight edge of the support side plate 3. The two sides of the cutting groove 32 are perpendicular to the corresponding two edges. A bending groove 33 is opened at the included angle of the edge with rounded corners. The depth of the bending groove 33 is less than the length of the side of the cutting groove 32, and the rounded corner is R50 to R150mm.

[0044] S3. Place the support side plate 3 in the stamping machine and stamp out the bent ear 34 and the reinforcing rib 36 to form a semi-finished product;

[0045] S4. Then, according to the drawings, stamp out the mounting holes for the chain conveyor drive mechanism or tensioning mechanism, or stamp them out in one go in step S3.

[0046] S5. The reinforcing member 10 is installed on the support side plate 3 by bolts, and then the two support side plates 3 are connected by the connector 4 to form the conveyor head frame or the conveyor tail frame.

[0047] The morphological optimization of the support side plate 3 after stamping mainly includes increasing the moment of inertia of the cross-section and enabling the stamping deformation structure to effectively disperse stress. Simultaneously, during the stamping deformation process, the outer layer of the support side plate 3 is under tension, and the inner layer is under compression, resulting in an increased strain gradient. The strain gradient is inversely proportional to the bending radius; the smaller the radius of curvature, the larger the strain gradient, and the higher the stress borne by the outer fiber layer. Furthermore, the material undergoes plastic deformation during the stamping deformation process, increasing the dislocation density and leading to work hardening, indirectly improving rigidity. By analyzing the stress-strain situation through simulation software and optimizing the design, the load-bearing requirement of 2T can be met. From a processing perspective, eliminating a large number of welding processes can significantly reduce production costs.

[0048] Furthermore, when the supporting side plate 3 is in the semi-finished product stage S3, different mounting holes can be opened according to the installation requirements of different installation equipment, making the supporting side plate 3 highly versatile.

[0049] Example 2:

[0050] Please see Figure 4 and Figure 5 As a further improvement to Embodiment 1, it also includes an extension frame 2 installed between the head and tail frames 1 of the conveyor;

[0051] The outer sides of both ends of the extended frame 2 are vertically fixed with mounting ears 5, and the bent ears 34 of the straight edge of the supporting side plate 3 are adapted to the mounting ears 5 to form a mounting part 6.

[0052] It also includes a reinforcing angle steel 7, one side of which is detachably connected to the mounting part 6 to strengthen the mounting part 6, and the other side of the reinforcing angle steel 7 that is not connected to the mounting part 6 is perpendicular to the supporting side plate 3.

[0053] The surface of the support side plate 3 near the mounting part 6 has a plug hole 9. A connecting rod 41 is inserted through the two support side plates 3 and protrudes from the support side plate 3 to form a force-bearing part 8. The other side of the reinforcing angle steel 7 that is not connected to the mounting part 6 is detachably connected to the force-bearing part 8.

[0054] In this embodiment:

[0055] By using the insertion hole 9 on the support side plate 3, the connecting rod 41 can pass through the support side plate 3 to form the force-bearing part 8. Then, with the addition of the reinforcing angle iron, the mounting part 6 can be supported. The reinforcing angle iron is bolted to the connecting rod 41 and the mounting part 6 on both sides. When reinforcing the mounting part 6, the connecting rod 41 is simultaneously limited. The reinforcing angle iron effectively transfers the tension when the mounting part 6 is connected to the mounting ear 5 to the connecting rod 41. After installation, the reinforcing angle iron with this configuration can support the vertical shear force generated by the extension frame 2 on the mounting part 6.

[0056] The above are merely embodiments of this utility model and are not intended to limit the scope of this utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principle of this utility model should be included within the scope of the claims of this utility model.
