Description

Technical Field

[0001] The present invention relates to the field of sintering equipment, in particular to a connection assembly of a bulk material hopper and a concrete beam and a connection method thereof. Background Art

[0002] The bulk material hopper is an essential component in the sintering project. In the sintering process, the bulk material hopper is used to collect the materials dropped from the sintering machine and then transport them to the designated location through the belt conveyor.

[0003] Since the platform where the sintering machine is located is usually a concrete structure, the bulk material hopper is located at the bottom of the platform where the sintering machine is located. Therefore, the bulk material hopper is usually installed on the concrete beam below the sintering machine. A common practice is to embed steel plates on the sides of the concrete beam around the bulk material funnel. The size of the embedded steel plates is arranged along the length of the concrete beam. The bulk material funnel is fixedly connected to the embedded steel plates by welding, thereby realizing the installation of the bulk material funnel.

[0004] However, after welding, the connection between the bulk material hopper and the embedded steel plate causes the side of the concrete beam to be subjected to stress, and the concrete beam is easily twisted and deformed under stress. At the same time, the welding workload between the embedded steel plate and the bulk material hopper is increased, which reduces the safety factor and work efficiency of the construction workers. Summary of the Invention

[0005] In order to improve the uneven stress on the concrete beam and reduce the difficulty of connecting the bulk material hopper and the concrete beam, the present application provides a connection assembly of the bulk material hopper and the concrete beam and a connection method thereof.

[0006] In a first aspect, the present application provides a connection assembly between a bulk material hopper and a concrete beam, which adopts the following technical solution:

[0007] A connection assembly for a bulk material hopper and a concrete beam, comprising a lap main plate, a connection plate and an adhesive layer;

[0008] The overlapping main plate is horizontally overlapped on the upper end surface of the concrete beam, and the width of the overlapping main plate is the same as the width of the concrete beam. Two connecting plates are arranged opposite to each other along the width direction of the overlapping main plate. The overlapping main plate is fixedly connected to the two connecting plates. The opposite end surfaces of the two connecting plates are in contact with the side walls in the width direction of the concrete beam. The adhesive layer is installed on the outer surface of the concrete beam and is bonded to the overlapping main plate and the connecting plate.

[0009] The concrete beam is located between the two bulk material hoppers, and the end surface of the connecting plate facing away from the other connecting plate is fixedly connected to the outer side wall of the bulk material hopper.

[0010] By adopting the above technical solution, a lap main plate is placed on the concrete beam, and the connecting plate abuts against the vertically arranged side wall of the concrete beam. The adhesive layer can fix the lap main plate on the concrete beam, thereby improving the connection strength between the connection component and the concrete beam. The bulk material hopper is fixed to the connecting plate, so that the two sides of the concrete beam are evenly stressed and not easily twisted. At the same time, the welding step between the concrete beam and the connecting component is saved, thereby improving the uneven stress of the concrete beam and reducing the difficulty of connecting the bulk material funnel to the concrete beam.

[0011] Preferably, the connecting plate and the bulk material hopper are welded and fixed with a weld height of not less than 8 mm.

[0012] By adopting the above technical solution, welding can be used to fix the bulk material hopper and the connecting plate, and the welding weld height is not less than 8mm to meet the connection strength between the bulk material hopper and the concrete beam.

[0013] Optionally, a mounting assembly is connected between the connecting plate and the bulk material hopper, and the mounting assembly includes an overlapping bottom plate, an overlapping long plate, a limiting member and a locking member;

[0014] The overlapping base plate is fixed to the end of the connecting plate away from the concrete beam, the overlapping long plate is fixed to the outer wall of the bulk material funnel and horizontally overlapped on the overlapping base plate, the limiting piece is used to limit the overlapping long plate, and the locking piece is used to lock the overlapping long plate and the overlapping base plate.

[0015] By adopting the above technical solution, in order to fix the bulk material hopper and the connecting plate, a lapped base plate can be fixed to the connecting plate, and a lapped long plate can be fixed to the bulk material hopper. The lapped long plate is placed on the lapped base plate, which can define the connection position between the bulk material hopper and the connecting plate, and at the same time, the position of the bulk material hopper is positioned to facilitate subsequent connection. The position of the lapped long plate is limited by a limiter to prevent shaking, and then the lapped long plate and the lapped base plate are locked by a locking member, thereby achieving the fixation of the bulk material funnel and the connecting plate. This fixing method not only achieves the connection between the bulk material funnel and the connecting plate, but also facilitates the removal of the bulk material funnel and the connecting plate if the bulk material funnel needs to be replaced.

[0016] Optionally, the limiting member includes a card plug-in block and a threaded push rod;

[0017] The side wall of the overlapping long plate facing the connecting plate is provided with a locking groove that is slidably connected to the locking block. The connecting plate is provided with a limiting groove for inserting the locking block. One end of the threaded push rod is connected to the locking block and is threadedly connected to the overlapping long plate along the sliding direction of the locking block.

[0018] By adopting the above technical solution, when the overlapping long board is placed on the overlapping base plate, the threaded push rod rotates forward to drive the card insert block to slide out of the card slot and into the limit slot, thereby achieving vertical limitation of the overlapping long board.

[0019] Optionally, the card block is cylindrical, one end of the card block is coaxially connected to the threaded push rod, and the other end of the card block is conical.

[0020] By adopting the above technical solution, in order to enable the card block to rotate with the threaded push rod, the card block is cylindrical in shape, and at the same time, the end of the card block facing away from the threaded push rod is conical, which can reduce the difficulty of the card block sliding into the limit groove, thereby reducing the difficulty of subsequent adjustment of the position of the overlapping long board.

[0021] Optionally, the locking member includes a locking base plate, a locking rod, a return spring and a linkage member;

[0022] A locking slot for the locking base plate to slide vertically is provided in the overlapping base plate, the locking rod is vertically installed on the locking base plate, a through hole is provided on the upper surface of the overlapping base plate for the locking rod to slide through, and a locking hole is provided on the overlapping long plate for the locking rod to slide into, the return spring is arranged vertically and one end is fixed to the overlapping base plate, and the other end of the return spring is connected to the bottom of the locking base plate;

[0023] The linkage member is used to push the locking base plate to slide upward when the card plug-in block is inserted into the limiting groove, and the reset spring is stretched and reset.

[0024] By adopting the above technical solution, when the card block slides into the limit groove, as the card block continues to slide and contacts the linkage part, the linkage part can control the locking base plate to move upward until the locking rod passes through the through hole and is inserted into the locking hole, thereby limiting the horizontal position of the overlapping long plate, thereby achieving locking of the overlapping long plate and the overlapping base plate.

[0025] Optionally, the linkage member includes a linkage slide rod and a linkage spring;

[0026] A linkage slide groove is provided in the connecting plate for the vertical sliding of the linkage slide rod, the linkage slide groove passes through the limit groove and is connected to the locking slide groove, the linkage slide rod is provided with a linkage through hole for the horizontal insertion of the card plug-in block, the top hole wall of the linkage through hole is a linkage inclined surface that slides against the card plug-in block, and the linkage inclined surface is arranged obliquely from top to bottom in a direction away from the card plug-in block;

[0027] The upper end surface of the locking base plate is provided with a contact with the bottom end of the linkage slide rod, the linkage spring is arranged vertically and one end is connected to the top of the linkage slide rod, and the other end of the linkage spring is fixed to the connecting plate. When the card block is inserted into the linkage slide groove, the linkage slide rod rises, the linkage spring contracts, the return spring extends, and the locking base plate rises.

[0028] By adopting the above technical solution, when the card block slides into the limit groove and continues to slide, the conical surface of the card block abuts against the linkage inclined surface. As the card block continues to slide, the linkage slide rod is pushed away from the locking base plate. The locking base plate rises due to the reset extension of the reset spring until the locking rod is inserted into the locking hole.

[0029] Optionally, the connecting plate is horizontally slidably connected to a clamping rod on the side away from the overlapping long plate, and a clamping groove for the clamping rod to slide is provided on the connecting plate, and the clamping groove is connected to the limit groove, and the clamping rod is in contact with the lower end surface of the concrete beam and one end of the clamping rod is located in the clamping groove and is in contact with the plug-in block.

[0030] By adopting the above technical solution, as the card block continues to move through the linkage slide rod, the card block abuts against the clamping rod and pushes the clamping rod to move together, and part of the clamping rod slides out of the connecting plate and abuts against the lower end face of the concrete beam, thereby further strengthening the connection strength between the concrete beam and the bulk material funnel.

[0031] Optionally, a control hole for the coaxial insertion of the plug-in block is provided on the clamping rod, an internal thread section connected to the threaded push rod is provided in the control hole, and the clamping groove is larger than the limiting groove.

[0032] By adopting the above technical solution, when the card insert is fully inserted into the control hole, as the card insert continues to be inserted, the threaded push rod is threadedly connected to the clamping rod, and then the threaded push rod rotates while driving the clamping rod to slide. When the overlapping long plate is detached from the overlapping base plate, the threaded push rod rotates in the opposite direction, and when the clamping rod slides to the intersection of the clamping groove and the limit groove, the clamping rod stops sliding, and the threaded push rod drives the card insert away from the limit groove, which not only allows the bulk funnel to be detached from the connecting plate, but also provides convenience for subsequent installation.

[0033] In a second aspect, the present application provides a method for connecting a bulk material hopper and a concrete beam, which adopts the following technical solution:

[0034] A method for connecting a bulk material hopper and a concrete beam comprises the following steps:

[0035] S1. Cut the overlapping main plate and two connecting plates according to the size of the concrete beam;

[0036] S2. Weld two connecting plates to the overlapping main plate. The connecting plates are fixed to the side walls of the overlapping main plate by welding. The distance between the two connecting plates is equal to the width of the concrete beam.

[0037] S3. Weld the bulk material hopper to the connecting plate;

[0038] S4. Installing a bonding layer on the top end surface of the concrete beam;

[0039] S5. Place the welded connecting plate and overlapping main plate of the bulk material hopper on the concrete beam, bond the bottom of the overlapping main plate to the bonding layer, and abut the two connecting plates against the surrounding wall of the concrete beam.

[0040] By adopting the above technical solution, when installing the bulk material hopper, the overlapping main board and the two connecting plates are first fixed, and then the bulk material funnel and the connecting plate are fixed, and then the overlapping main board is installed on the concrete beam by hoisting. Compared with the connection method between the bulk material funnel and the concrete beam in the prior art, the two connecting plates of the present application can be connected to the two bulk material funnels. The overlapping main board makes the concrete beam evenly stressed and not easily twisted, and saves the welding steps between the concrete beam and the overlapping main board and the connecting plate, thereby improving the uneven stress of the concrete beam as a whole and reducing the difficulty of connecting the bulk material funnel and the concrete beam.

[0041] In summary, this application includes at least one of the following beneficial technical effects:

[0042] 1. Place the lap main plate on the concrete beam, and the connecting plate abuts against the vertical side wall of the concrete beam. Since the bulk material funnel is fixed on the connecting plate, the force on both sides of the concrete beam is evenly distributed and not easily twisted, thereby improving the uneven force on the concrete beam and reducing the difficulty of connecting the bulk material funnel to the concrete beam;

[0043] 2. Placing the overlapping long plate on the overlapping bottom plate can position the bulk material funnel, so that the subsequent limiting parts can limit the position of the overlapping long plate, and the overlapping long plate and the overlapping bottom plate can be locked by the locking parts to facilitate the subsequent loading and unloading of the bulk material funnel;

[0044] 3. After the card block slides into the limit groove, it continues to slide. The conical surface of the card block abuts against the linkage inclined surface, and pushes the linkage slide rod to rise away from the locking base plate. The reset spring stretches and drives the locking base plate to rise, and the locking rod is inserted into the locking hole. BRIEF DESCRIPTION OF THE DRAWINGS

[0051] The following is combined with Figure 1-4 This application is described in further detail.

[0052] Example 1

[0053] Example 1 of the present application discloses a connection assembly between a bulk material hopper and a concrete beam.

[0054] It should be noted that, in the description of the present invention, it should be understood that the terms "center", "longitudinal", "lateral", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", etc., indicating the orientation or position relationship, are based on the orientation or position relationship shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention.

[0055] Reference Figure 1 The connection component includes a lap main board 1, a connection board 2 and an adhesive layer 3.

[0056] The main overlap plate 1 is horizontally overlapped on the upper end face of the concrete beam 6, and its width is the same as that of the concrete beam 6. The adhesive layer 3 is installed on the upper end face of the concrete beam 6 and bonded to the main overlap plate 1. Two connecting plates 2 are positioned opposite each other along the width of the main overlap plate 1, and the main overlap plate 1 is welded to the two connecting plates 2. When the main overlap plate 1 is overlapped on the upper end face of the concrete beam 6, the two connecting plates 2 are located on opposite horizontal sides of the concrete beam 6, and the connecting plates 2 abut the side walls of the concrete beam 6 in the width direction.

[0057] Concrete beam 6 is located between two bulk material hoppers 7, and two connecting plates 2 are connected to different bulk material hoppers 7. When the bulk material hoppers 7 are installed on concrete beam 6, the outer peripheral wall of the bulk material hopper 7 is welded to the side wall of the connecting plate 2 facing away from the concrete beam 6. The weld height is at least 8mm to ensure the connection strength between the bulk material hopper 7 and the connecting plate 2. Fixing the bulk material hopper 7 to the connecting plate 2 and overlapping the main plate 1 and the two connecting plates 2 ensures that the force on both sides of the concrete beam 6 is evenly distributed and not easily distorted. This also saves welding steps between the concrete beam 6 and the connecting assembly, improves the uneven force on the concrete beam 6, and reduces the difficulty of connecting the bulk material hopper 7 to the concrete beam 6.

[0058] 220m 2 Taking the belt sintering machine project as an example, the lap main plate 1 is preferably made of a steel plate with a thickness of 20 mm and the same width and length as the concrete beam 6, and the connecting plate 2 is preferably made of a steel plate with a thickness of 20 mm and a width of 300 mm and the same length as the concrete beam 6. The lap main plate 1 and the connecting plate 2 are welded by cutaway welding and the material specification is Q235B. The lap main plate 1 and the concrete beam 6 are fixed with steel glue, and the bulk material funnel 7 is welded to the connecting plate 2 with a weld height of preferably 8 mm, and full welding. Compared with the existing technology, the present application saves about 18 kg / m of anchor bars along the length of the concrete beam 6, reduces the on-site welding operation time by 1 / 2, and effectively saves construction time.

[0059] The implementation principle of a connection assembly of a bulk material hopper and a concrete beam in Example 1 of the present application is as follows: two connecting plates 2 are welded to a lap main board 1, a bulk material hopper 7 is welded to the connecting plate 2, and the lap main board 1 is fixed to the concrete beam 6 through an adhesive layer 3, so that the pulling force of the bulk material funnel 7 on the connecting plate 2 is evenly distributed around the concrete beam 6, thereby improving the uneven force on the concrete beam 6. At the same time, the lap main board 1 is bonded and fixed to the concrete beam 6, which also reduces the difficulty of connecting the bulk material funnel 7 to the concrete beam 6.

[0060] Example 1 of the present application further discloses a method for connecting a bulk material hopper and a concrete beam, which is applied to a connection assembly of a bulk material hopper and a concrete beam, comprising the following steps:

[0061] S1. Cut the overlapping main plate 1 and the two connecting plates 2 according to the size of the concrete beam 6;

[0062] S2. Weld two connecting plates 2 onto the overlapping main plate 1. The connecting plates 2 are welded and fixed to the side walls of the overlapping main plate 1. The distance between the two connecting plates 2 is the width of the concrete beam 6.

[0063] S3, welding the bulk material hopper 7 to the connecting plate 2;

[0064] S4, installing the bonding layer 3 on the top end surface of the concrete beam 6;

[0065] S5. Hoist the connection plate 2 and the overlapping main plate 1 with the welded bulk material funnel 7 and place them on the concrete beam 6. The bottom of the overlapping main plate 1 is bonded to the adhesive layer 3. Both connection plates 2 are in contact with the surrounding wall of the concrete beam 6.

[0066] The two connecting plates 2 of the present application can be connected to the two bulk material funnels 7. By overlapping the main board 1, the concrete beam 6 is evenly stressed and not easily twisted, which saves the welding steps between the concrete beam 6 and the overlapping main board 1 and the connecting plate 2, thereby improving the overall uneven stress of the concrete beam 6 and reducing the difficulty of connecting the bulk material funnel 7 and the concrete beam 6.

[0067] Example 2

[0068] Reference Figure 2 and Figure 3 The difference between this embodiment 2 and embodiment 1 is that an installation component 4 is connected between the connecting plate 2 and the bulk material funnel 7, and the installation component 4 includes a lap bottom plate 41, a lap long plate 42, a limit member 43 and a locking member 44.

[0069] Among them, the overlapping bottom plate 41 is fixed to the end of the connecting plate 2 away from the concrete beam 6, and the overlapping long plate 42 is fixed to the outer wall of the bulk material funnel 7. When the bulk material funnel 7 is connected to the connecting plate 2, the overlapping long plate 42 is horizontally overlapped on the upper end surface of the overlapping bottom plate 41 to preliminarily limit the bulk material funnel 7.

[0070] like Figure 3 and Figure 4 As shown, the limiting member 43 includes a snap-in block 431 and a threaded push rod 432. A snap-in slot 421 is provided on the sidewall of the overlapping long plate 42 facing the connecting plate 2, which is slidably connected to the snap-in block 431. The connecting plate 2 is provided with a limiting slot 21 for the snap-in block 431 to be inserted into. One end of the threaded push rod 432 is connected to the snap-in block 431 and is threadedly connected to the overlapping long plate 42 along the sliding direction of the snap-in block 431. When the threaded push rod 432 rotates in the forward direction, it pushes the snap-in block 431 into the limiting slot 21, thereby limiting the vertical position of the bulk material hopper 7.

[0071] In order to make the card block 431 rotate with the threaded push rod 432, the card block 431 is cylindrical, and one end of the card block 431 is coaxially connected to the threaded push rod 432. The other end of the card block 431 is conical to reduce the difficulty of sliding the card block 431 into the limiting groove 21.

[0072] In addition, the locking member 44 includes a locking base plate 441 , a locking insert rod 442 , a return spring 443 and a linkage member.

[0073] The overlapping base plate 41 defines a locking slot 411 for the vertical sliding of the locking base plate 441. A locking rod 442 is vertically mounted on the locking base plate 441. A through-hole 412 is defined on the upper end surface of the overlapping base plate 41, through which the locking rod 442 slides. The overlapping long plate 42 defines a locking hole 422, into which the locking rod 442 slides. A return spring 443 is vertically arranged, with one end fixed to the overlapping base plate 41 and the other end connected to the bottom of the locking base plate 441.

[0074] When the overlapping long plate 42 is placed on the overlapping bottom plate 41 , the return spring 443 is in a contracted state, and the locking rod 442 is located in the locking sliding groove 411 and the through hole 412 .

[0075] In addition, the linkage member includes a linkage slide rod 444 and a linkage spring 445 .

[0076] The connecting plate 2 is provided with a linkage slot 22 for the vertical sliding of the linkage slide 444. Since the overlapping base plate 41 is fixed to the connecting plate 2, the linkage slot 22 extends through the limiting slot 21 and communicates with the locking slot 411. A linkage through hole 446 is provided on the peripheral wall of the linkage slide 444, directly opposite the limiting slot 21, for the horizontal insertion of the plug-in block 431. The top wall of the linkage through hole 446 is a linkage inclined surface 447 that slides against the plug-in block 431. The linkage inclined surface 447 is arranged downwardly, slanting away from the plug-in block 431. The upper end surface of the locking base plate 441 is provided with a linkage spring 445 that abuts the bottom end of the linkage slide 444. A linkage spring 445 is arranged vertically, one end of which is connected to the top of the linkage slide 444. The other end of the linkage spring 445 is fixed to the connecting plate 2.

[0077] When the card plug-in block 431 has not slid to the linkage slide rod 444 , the linkage spring 445 is in an extended state, the lower end surface of the linkage slide rod 444 is pressed against the locking base plate 441 , the return spring 443 is in a compressed state, and the locking plug rod 442 is located in the through hole 412 .

[0078] When the card insert block 431 slides to abut against the linkage inclined surface 447, as the card insert block 431 continues to penetrate the limiting groove 21, the linkage slide bar 444 is pushed upward, the linkage slide bar 444 moves away from the locking base plate 441, the linkage spring 445 contracts, and the return spring 443 extends and resets, thereby driving the locking base plate 441 to slide vertically upward, and then driving the locking insert rod 442 to pass through the through hole 412 and insert into the locking hole 422, thereby achieving the horizontal limitation of the bulk material funnel 7, and combining with the limiting member 43 to achieve the fixation of the bulk material funnel 7. The installation assembly 4 not only can achieve the fixation of the bulk material funnel 7, but also facilitates the disassembly of the bulk material funnel 7, and enhances the connection flexibility between the bulk material funnel 7 and the concrete beam 6.

[0079] Since the lap bottom plate 41 and the connection plate 2 are hollow inside, in order to further improve the connection strength between the connection plate 2 and the concrete beam 6, refer to Figure 3 and Figure 4 The connecting plate 2 is horizontally slidably connected to the side of the overlapping long plate 42 with a tightening rod 5. The tightening rod 5 is a cylindrical long rod. The connecting plate 2 is provided with a tightening groove 23 for the tightening rod 5 to slide. The tightening groove 23 is connected to the limiting groove 21 and the size of the tightening groove 23 is larger than the limiting groove 21, so as to limit the sliding distance of the tightening rod 5.

[0080] Among them, the clamping rod 5 is located on the side of the linkage slide rod 444 away from the overlapping long plate 42, and a control hole 51 for the coaxial insertion of the card plug-in block 431 is opened at one end of the clamping rod 5 facing the card plug-in block 431, and an internal thread section connected to the threaded push rod 432 is provided in the control hole 51.

[0081] When the card inserting block 431 is not inserted into the control hole 51 , the abutting rod 5 is completely located in the abutting groove 23 .

[0082] When the card block 431 is inserted into the control hole 51, the threaded push rod 432 is threadedly connected to the internal thread section of the clamping rod 5 until the card block 431 abuts against the bottom of the control hole 51. The threaded push rod 432 continues to rotate forward, thereby driving the clamping rod 5 to slide out of the clamping groove 23 while rotating. The peripheral wall of the clamping rod 5 located outside the clamping groove 23 abuts against the lower end face of the concrete beam 6, thereby further increasing the connection strength between the connecting plate 2 and the concrete beam 6.

[0083] And when the threaded push rod 432 rotates in the opposite direction, the threaded push rod 432 drives the clamping rod 5 to slide into the clamping groove 23 until the clamping rod 5 and the clamping groove 23 are opposite to the notch of the limit groove 21, the clamping rod 5 stops sliding, and the threaded push rod 432 continues to rotate in the opposite direction, so that the threaded push rod 432 drives the card plug-in block 431 to gradually move away from the clamping rod 5, the linkage slide rod 444 and the connecting plate 2, the linkage slide rod 444 descends, and the locking plug-in rod 442 disengages from the locking hole 422, thereby completing the disassembly between the overlapping long plate 42 and the overlapping bottom plate 41.

[0084] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
