[0002] The scraper conveyor is one of the main equipments for mining, and the middle trough plays an important role in load bearing and guiding in the scraper conveyor. The middle trough with the traditional tenon structure has a certain gap at the tenon. When the middle trough is relatively bent, the gap at the tenon becomes larger. When the scraper passes through the middle plate interface, a certain vibration and impact will occur due to the middle plate misalignment, especially when the coal mining machine passes through, the vibration and impact are larger, which affects the service life of the middle trough.

[0003] The middle trough comprises a left trough side wall, a right trough side wall, a middle plate and a bottom plate.

[0069] The preferred embodiments of the present application are described below in conjunction with the accompanying drawings. It should be understood that the preferred embodiments described herein are only used to illustrate and explain the present application and are not used to limit the present application.

[0070] like Figures 1 to 5 、 Figure 8 As shown, according to the first aspect of the embodiment of the present application, a middle groove connecting seat is proposed, including: a first main body 11 and a second main body 12; a first give way groove 13 is provided on the first main body 11, and the first end of the first main body 11 is connected to the end face of the supporting member 15; a second give way groove 14 is provided on the second main body 12, and the first end of the second main body 12 is connected to the end face of the supporting member 15; the first main body 11 is connected to the second main body 12, and the second give way groove 14 is connected to the first give way groove 13 to form an accommodating cavity.

[0071] The middle trough connecting seat provided in the embodiment of the present application adopts a split structure. The connecting seat as a whole is formed by connecting the first main body 11 and the second main body 12 after docking. The first clearance groove 13 set on the first main body 11 and the second clearance groove 14 set on the second main body 12 form a accommodating cavity after the first main body 11 and the second main body 12 are docked to realize the accommodating function of the dumbbell pin and reserve space for the installation of the dumbbell pin. After the first main body 11 and the second main body 12 are connected, they are connected to the supporting member 15 of the middle trough. The connecting seat as a whole and the supporting member 15 also adopt a split structure. When the connecting seat is damaged, the connecting seat can be replaced by separating the connecting seat from the supporting member 15 without replacing the entire middle trough, thereby reducing the maintenance cost and difficulty of the middle trough and shortening the maintenance time of the scraper.

[0072] Further, such as Figure 5 The two ends of the carrier 15 are connected to a coupling seat, forming the channel side of the middle channel. Specifically, one end of the carrier 15 is connected to the male coupling seat 23, and the other end of the carrier 15 is connected to the female coupling seat 24. The mortise and tenon structure of the two channel sides cooperates to achieve the docking of the middle channel, and then the dumbbell pin is installed to achieve the connection of the middle channel. As a preferred embodiment, the carrier 15 is a channel steel.

[0073] As a preferred solution, the connecting seat is welded to the supporting member 15 to ensure the overall structural connection strength of the groove side; when the connecting seat needs to be replaced, the welding point between the connecting seat and the supporting member 15 is cut to separate the connecting seat and the supporting member 15, and the connecting seat can be replaced.

[0074] As a preferred solution, the first body 11 and the second body 12 are stacked vertically, and the connecting seat is a symmetrical structure with the joint surface of the first body 11 and the second body 12 as the symmetrical plane, so as to reduce the directional restriction during the installation of the dumbbell pin, which is conducive to reducing the difficulty of installing the dumbbell pin.

[0075] like Figure 6 and Figure 7 As shown, in a feasible embodiment, the middle groove connecting seat also includes: a connecting member 16, the first end of the connecting member 16 is connected to the first body 11, and the second end of the connecting member 16 is connected to the second body 12 to connect the second body 12 to the first body 11.

[0076] In this technical solution, the two ends of the connecting member 16 are respectively connected to the first body 11 and the second body 12. The first body 11 and the second body 12 are connected through the connecting member 16 to form a connecting seat, so as to reduce the assembly difficulty of the connecting seat and help improve the production efficiency of the connecting seat.

[0077] Furthermore, the connecting member 16 is welded to the first body 11 , and the connecting member 16 is welded to the second body 12 to ensure the structural firmness and reliability of the entire connecting base.

[0078] It is understood that connecting the first body 11 and the second body 12 via the connector 16 can reduce the welded area of ​​the first body 11 and the second body 12, thereby reducing deformation caused by the connection of the first and second bodies 11, 12. When the first body 11 / second body 12 needs to be replaced, only the connector 16 needs to be cut, without damaging the other half of the connector base, that is, the other second body / first body, further reducing the maintenance cost of the connector base.

[0079] Furthermore, the connecting member 16 is arranged on the side of the first main body 11 away from the first give way groove 13, so as to avoid welding deformation of the first give way groove 13 when the connecting member 16 is welded to the first main body 11, thereby ensuring the dimensional accuracy of the first give way groove 13; the connecting member 16 is arranged on the side of the second main body 12 away from the second give way groove 14, so as to avoid welding deformation of the second give way groove 14 when the connecting member 16 is welded to the second main body 12, thereby ensuring the dimensional accuracy of the second give way groove 14, thereby ensuring that the dumbbell pin can be smoothly installed in the accommodating cavity.

[0080] Furthermore, the connecting member 16 is disposed along the height direction of the first body 11 to ensure the connection length between the connecting member 16 and the first body 11 and the second body 12, thereby improving the connection strength between the connecting seat structures.

[0081] like Figure 3 and Figure 4 As shown, in a feasible embodiment, the middle groove connecting seat also includes: a first connecting groove 17 and a second connecting groove 18; the first connecting groove 17 is arranged on the side of the first main body 11 away from the first make way groove 13, and the first end of the connecting member 16 is embedded in the first connecting groove 17; the second connecting groove 18 is arranged on the side of the second main body 12 away from the second make way groove 14, and the second end of the connecting member 16 is embedded in the second connecting groove 18. The first main body 11 is connected to the second main body 12 so that the second connecting groove 18 is docked with the first connecting groove 17 to form a positioning cavity.

[0082] In this technical solution, after the first body 11 and the second body 12 are connected, the second connecting groove 18 is docked with the first connecting groove 17 to form a positioning cavity for the connecting member 16. The two ends of the connecting member 16 are respectively embedded in the first connecting groove 17 and the second connecting groove 18, thereby increasing the contact area between the connecting member 16 and the first body 11 and the second body 12, thereby improving the firmness and reliability of the connection between the connecting member 16 and the first body 11 and the second body 12, thereby making the overall structure of the connecting seat more reliable. The first connecting groove 17 is set on the side of the first body 11 away from the first clearance groove 13, and the second connecting groove 18 is set on the side of the second body 12 away from the second clearance groove 14, so that the welding position of the connecting member 16 is away from the accommodating cavity, ensuring that the size of the accommodating cavity remains unchanged after welding, and ensuring that the dumbbell pin can be smoothly installed in the accommodating cavity.

[0083] Further, the shape of the first end of the connecting piece 16 is adapted to the shape of the first connecting groove 17, and the shape of the second end of the connecting piece 16 is adapted to the shape of the second connecting groove 18. When the connecting piece 16 is installed into the first connecting groove 17 and the second connecting groove 18, the connecting piece 16 can function to limit the first main body 11 and the second main body 12, prevent the first main body 11 and the second main body 12 from moving, prevent the first displacement groove 13 and the second displacement groove 14 from being misaligned, and ensure the dimensional accuracy of the accommodating cavity.

[0084] As shown in Figure 7 , Figures 11 to 13 in an available embodiment, the first main body 11 is located above the second main body 12, and the first connecting groove 17 comprises: a butt joint groove 171 and a limiting groove 172. The butt joint groove 171 is arranged along the height direction of the first main body 11, and the lower end of the butt joint groove 171 is connected with the second connecting groove 18. The limiting groove 172 is arranged above the butt joint groove 171, and the limiting groove 172 is connected with the upper end of the butt joint groove 171.

[0085] The connecting piece 16 comprises: a positioning part 161 and a limiting part 162. At least part of the positioning part 161 is embedded into the butt joint groove 171. The limiting part 162 is connected with the positioning part 161, and the limiting part 162 is embedded into the limiting groove 172.

[0086] In this technical solution, the positioning part 161 is embedded into the butt joint groove 171, the limiting part 162 is embedded into the limiting groove 172, the first main body 11 is located above the second main body 12, the limiting groove 172 is arranged above the first main body 11, and the limiting groove 172 is connected with the butt joint groove 171. The limiting groove 172 supports and limits the limiting part 162. When the connecting piece 16 is welded with the first main body 11 and the second main body 12, the connecting piece 16 is not easy to move, which is beneficial to reduce the welding difficulty of the connecting piece 16 and improve the assembly efficiency of the butt joint group.

[0087] Further, the limiting groove 172 is arranged perpendicularly to the butt joint groove 171, the first connecting groove 17 is in T shape, and the butt joint groove 171 and the second connecting groove 18 are connected. The butt joint groove 171 and the second connecting groove 18 limit the positioning part 161 left and right, and the limiting groove 172 limits the limiting part 162 downward, which prevents the connecting piece 16 from moving, and further prevents the first main body 11 and the second main body 12 from moving.

[0088] As shown in Figure 9 and Figure 10As shown, in a feasible embodiment, the middle groove connecting seat also includes: a first plug-in portion 19 and a second plug-in portion 20; the first plug-in portion 19 is arranged on the second side of the first main body 11, and the first plug-in portion 19 protrudes in the direction away from the first main body 11 along the length direction of the first main body; the second plug-in portion 20 is arranged on the second side of the second main body 12, and the second plug-in portion 20 protrudes in the direction away from the second main body 12 along the length direction of the second main body. The second body is connected to the first body so that the second plug-in portion 20 is docked with the first plug-in portion 19 to form a convex head structure.

[0089] In this technical solution, a first plug-in portion 19 is provided on a side surface of the first main body 11 facing away from the carrier 15, and a second plug-in portion 20 is provided on a side surface of the second main body 12 facing away from the carrier 15. When the first main body is connected to the second main body, the first plug-in portion 19 and the second plug-in portion 20 are also docked on the side of the connecting seat facing away from the carrier 15 to form a convex head structure, forming a convex connecting seat 23. By plugging the convex connecting seat 23 with the concave connecting seat 24, the two connecting seats are docked, and the two middle grooves are docked to facilitate the installation of the dumbbell pin.

[0090] Furthermore, the first plug-in portion 19 and the second plug-in portion 20 are symmetrically arranged with the joining surface of the first body 11 and the second body 12 being the symmetrical plane.

[0091] like Figure 11 and Figure 12 As shown, in a feasible embodiment, the middle slot connector also includes: a first plug-in slot 21 and a second plug-in slot 22; the first plug-in slot 21 is arranged on the second side of the first main body 11, and the first plug-in slot 21 is recessed toward the interior of the first main body 11 along the length direction of the first main body; the second plug-in slot 22 is arranged on the second side of the second main body 12, and the second plug-in slot 22 is recessed toward the interior of the second main body 12 along the length direction of the second main body, and the second main body is connected to the first main body so that the second plug-in slot 22 is docked with the first plug-in slot 21 to form a recessed structure; wherein, the first plug-in slot 21 is adapted to the shape of the first plug-in portion 19, and the shape of the second plug-in slot 22 is adapted to the shape of the second plug-in portion 20.

[0092] In this technical solution, a first plug-in slot 21 is provided on a side surface of the first main body 11 facing away from the carrier 15, and a second plug-in slot 22 is provided on a side surface of the second main body 12 facing away from the carrier 15. When the first main body is connected to the second main body, the first plug-in slot 21 and the second plug-in slot 22 are also docked on the side of the connecting seat facing away from the carrier 15 to form a recessed structure, forming a recessed connecting seat 24; at the same time, the first plug-in slot 21 is adapted to the shape of the first plug-in portion 19, and the shape of the second plug-in slot 22 is adapted to the shape of the second plug-in portion 20. When the first main body 11 is connected to the second main body 12, the convex head structure of one connecting seat can be inserted into the recessed structure of the other connecting seat, and then connected with the convex connecting seat 23 through the concave connecting seat 24, so as to achieve stable docking of the two connecting seats, so as to facilitate the installation of the dumbbell pin.

[0093] Furthermore, the first inserting slot 21 and the second inserting slot 22 are symmetrically arranged with the joining surface of the first body 11 and the second body 12 as a symmetrical plane.

[0094] It can be understood that after the convex connecting seat 23 of one middle groove is plugged into the concave connecting seat 24 of another middle groove, one end of the dumbbell pin is embedded in the accommodating cavity of the convex connecting seat 23, and the other end of the dumbbell pin is embedded in the accommodating cavity of the concave connecting seat 24, so as to connect one convex connecting seat 23 and one concave connecting seat 24 through the dumbbell pin, thereby realizing the connection of the two middle grooves.

[0095] It can be understood that although different sizes of connecting seats may be required to match middle grooves of different sizes, the mortise and tenon structures of the male and female connections are basically the same in size. By installing a pad on the connecting seat to adjust the height of the plug-in groove and the plug-in part, the mortise and tenon structure of the male connecting seat 23 and the female connecting seat 24 can be docked. Pads, connecting blocks and other structures can also be installed on the upper and lower parts of the connecting seat to adjust the overall size of the connecting seat. There is no need to adjust the bearing member 15 to achieve connection of different middle grooves. It is easy to install and adjust, and has a wide range of applications.

[0096] like Figure 14 As shown, according to the second aspect of the present application, a method for manufacturing a middle groove connector is proposed, which is used to manufacture the middle groove connector as described in any one of the above technical solutions. The manufacturing method includes:

[0097] Step 100: Forging the first main body 11 and forming a first clearance groove 13 on the first main body 11;

[0098] Step 200: Forging the second body 12 and forming a second clearance groove 14 on the second body 12;

[0099] Step 300 : docking the second clearance groove 14 with the first clearance groove 13 to connect the second body 12 and the first body 11 .

[0100] Through the manufacturing method of the middle groove connector provided in the embodiment of the present application, the first body 11 and the second body 12 are forged independently, and the first clearance groove 13 and the second clearance groove 14 are connected to ensure that after the first body 11 and the second body 12 are connected, the dumbbell pin can be embedded in the accommodating cavity surrounded by the first clearance groove 13 and the second clearance groove 14. Forging can improve the internal structure of the material, enhance the wear resistance and impact resistance of the connector as a whole, reduce the tendency of the connector to crack, and extend the service life of the connector; the first body 11 and the second body 12 of the connector are forged separately and then connected. The structure of the first body 11 and the second body 12 is simpler than that of the integral connector structure, which can shorten the processing process, simplify the production process, and facilitate the control and shortening of the production cycle of the connector, thereby improving production efficiency.

[0101] Furthermore, by placing the blank in a die for forging, the first clearance groove 13 can be directly formed on the first body 11 and the second clearance groove 14 can be directly formed on the second body 12, with good forming effect and simple process.

[0102] It can be understood that compared with directly forging the connecting seat, forging the first body 11 and the second body 12 separately has a simpler structure, can be formed in one step, and there is no need to adjust the position of the forging during the forging process. It can also save the process steps of flattening and bending during the overall forging. The production cycle is short, the production difficulty is low, and batch manufacturing of the connecting seat can be achieved, with higher output. The connecting seat can be adapted to the middle groove of different scraper models by simple modifications such as adding pads.

[0103] As a preferred solution, the first body 11 is forged from round steel with a diameter of φ260 to φ320, and the second body 12 is forged from round steel with a diameter of φ260 to φ320.

[0104] In a feasible embodiment, the manufacturing method further includes:

[0105] A first connecting groove 17 is formed on the first body 11;

[0106] A second connecting groove 18 is made on the second body 12;

[0107] Make the connecting piece 16 according to the shape of the first connecting groove 17 and the second connecting groove 18;

[0108] The first end of the connecting member 16 is inserted into the first connecting groove 17, and the second end of the connecting member 16 is inserted into the second connecting groove 18;

[0109] The first end of the connecting member 16 is welded to the first body 11 , and the second end of the connecting member 16 is welded to the second body 12 .

[0110] In this technical solution, the first body 11 and the second body 12 are connected by a connecting member 16. The connecting member 16 is simultaneously embedded in the first connecting groove 17 and the second connecting groove 18, and the shape of the connecting member 16 matches the first connecting groove 17 and the second connecting groove 18 to prevent the first body 11 and the second body 12 from relative displacement during the welding process with the connecting member 16. The connecting member 16 limits the first body 11 and the second body 12, thereby ensuring the accuracy of the docking of the first make way groove 13 and the second make way groove 14 after the first body 11 and the second body 12 are connected.

[0111] In some examples, the first connecting groove 17 can be directly formed on the first body 11 and the second connecting groove 18 can be directly formed on the second body 12 by placing the blank in a die for forging, which has a good forming effect and a simple process. Alternatively, the first connecting groove 17 can be machined on the first body 11 and the second connecting groove 18 can be machined on the second body 12 using processing equipment, so as to facilitate flexible selection according to on-site working conditions.

[0112] In one feasible embodiment, the forging method of the main body includes:

[0113] Heating the blank and keeping it warm;

[0114] The heated blank is placed in the lower die, and the upper die is fastened to forge to form a forging;

[0115] Place the forging into a trimming die and perform trimming on the forging;

[0116] Place the forging into a straightening die and perform straightening treatment on the forging;

[0117] Normalizing the forgings;

[0118] After the forgings are quenched, they are kept warm.

[0119] In this technical solution, the forging dies used for the first body 11 and the second body 12 are different but the forging process is the same. The blank is first heated and insulated, placed in the lower die, and then the upper die is forged after being fastened to form the structure of the main body by utilizing the thermal fluidity of the metal. The formed forging is then placed in the trimming die to trim off the excess metal flowing on the parting surface, and then the trimmed forging is placed in the correction die to correct the bend to obtain the main body. Finally, normalizing, quenching and insulation treatment are performed to eliminate the forging stress of the main body, refine the metal material grains, and uniformly organize the structure to improve the comprehensive mechanical properties of the main body.

[0120] In a feasible implementation manner, the first body 11 is made of 30CrMo alloy steel, and the second body 12 is made of 30CrMo alloy steel.

[0121] In this technical solution, 30CrMo alloy steel has good forging ductility, fast forming and good forming effect, which can improve the meshing performance of the convex connecting seat 23 and the concave connecting seat 24. The first main body 11 and the second main body 12 forged with 30CrMo alloy steel have good toughness and strength. The connecting seat is not easy to crack or break when moving forward during coal mining, is not easy to be damaged, and has a long service life.

[0122] It is understandable that the material of the bearing member 15 is NM400, NM450 steel, and the forging made of 30CrMo alloy steel has better weldability with the bearing member 15, which can ensure the welding strength between the connecting seat and the bearing member 15 and improve the structural reliability of the middle groove.

[0123] The manufacturing method of the middle groove connecting seat provided in the embodiment of the present application is applied to the middle groove connecting seat of any of the above-mentioned technical solutions. Therefore, the manufacturing method of the middle groove connecting seat has all the beneficial effects of the middle groove connecting seat of the above-mentioned technical solutions, which will not be repeated here.

[0124] Example:

[0125] Calculate the material usage and forging loss based on the design structure of the first main body 11. The material for the first main body 11 is round steel with a diameter of φ300 and a material of 30CrMo. First, heat the round steel blank to 1180℃ and keep it warm for 3 hours. Place the heated round steel blank into the lower die of the first main body 11, close the upper die, and forge it. Utilize the thermal fluidity of the metal to form the first main body 11 forging. Place the first main body 11 forging into the trimming die for trimming and remove excess metal flowing on the parting surface. Place the trimmed first main body 11 forging into the correction die to correct the bend. Heat the corrected first main body 11 forging to 860℃, keep it warm for 3.5 hours, and then anneal it in water. Finally, heat the first main body 11 to 550℃, keep it warm for 3.5 hours, temper it, and air-cool it at room temperature.

[0126] A first connecting groove 17 is processed on the first body 11 using processing equipment.

[0127] The second body 12 mold is used to manufacture the second body 12 using the same process.

[0128] A second connecting groove 18 is machined on the second body 12 using a machining device;

[0129] Place the first body 11 on top of the second body 12 so that the first accommodating cavity is connected to the second accommodating cavity, place the connecting piece 16 into the first connecting groove 17 and the second connecting groove 18, first weld the connecting piece 16 to the first body 11, and then weld the connecting piece 16 to the second body 12 to form a connecting seat.
