Description

Technical Field

[0001] The present application relates to the technical field of crushers, and in particular to a wear-resistant cladding grate plate with a honeycomb structure skeleton. Background Art

[0002] The single-roller grate plate is the main component installed on the sintering machine to receive the sintered parts and assist in crushing. Its service life directly affects the productivity of the sintering machine. A wear-resistant layer is welded on one side of the grate plate. During the welding process, it is usually necessary to manually fix the steel plate on the welding surface of the grate plate, open multiple 100x100mm grids on the steel plate, and weld the welding wire in the grid until it is flat, completing the wear-resistant layer welding.

[0003] In the related art, welding wire is overlay-welded in the mesh. However, due to the large size of the mesh and the disadvantages of the welding wire being hard and brittle, the wear-resistant layer of the overlay may fall off during the use of the single-roller grate plate, thus affecting the service life of the grate plate. Utility Model Content

[0004] In order to reduce the adverse effects on the service life of the grate plate, the present application provides a honeycomb structure skeleton wear-resistant cladding grate plate.

[0005] The present application provides a honeycomb structure skeleton wear-resistant cladding grate plate adopts the following technical solution:

[0006] A honeycomb structure skeleton wear-resistant cladding grate plate comprises a plate body, both sides of which are provided with a plurality of oppositely arranged fixing holes, the diameter of the fixing holes is 40 mm, both ends of the plate body in the length direction are fixedly connected with wear-resistant layers, and the inner side walls oppositely arranged with fixing columns corresponding to the fixing holes are fixedly connected, and the fixing columns are inserted into the corresponding fixing holes and fixedly connected to the fixing holes.

[0007] By adopting the above technical scheme, the wear-resistant layer is fixed on the plate body. At this time, the fixing columns are inserted into the corresponding fixing holes, which increases the contact area between the wear-resistant layer and the plate body, thereby increasing the bonding strength between the wear-resistant layer and the plate body. The diameter of the fixing holes is small, which further increases the bonding strength between the wear-resistant layer and the plate body, reduces the possibility of the wear-resistant layer falling off the plate body, and reduces the adverse effects on the service life of the grate plate.

[0008] Optionally, the fixing holes on the side wall of the plate body are arranged in multiple rows along the height direction of the plate body, the fixing holes at both ends of the plate body are arranged opposite to each other, the number of the fixing holes in each row on the same side of the plate body and located at the same end of the plate body is in a honeycomb shape that gradually decreases along the height direction of the plate body, and the fixing holes in each row arranged along the height direction of the plate body are located between two adjacent fixing holes in the previous row.

[0009] By adopting the above technical solution, the fixing holes at the ends of the plate body and located on the same side are arranged in a honeycomb shape, and the bonding strength between the wear-resistant layer and the plate body is further increased through the fixing columns, thereby reducing the possibility of the wear-resistant layer falling off the plate body and reducing the adverse effects on the service life of the grate plate.

[0010] Optionally, upper ends of the wear-resistant layers on the sides close to each other are provided with inclined surfaces inclined in a direction away from each other.

[0011] By adopting the above technical solution, when the plate body is installed on the crusher for use, the inclined surface on the wear-resistant layer allows the material on the crusher to move along the inclined surface, reducing the possibility of material pile-up, thereby reducing the possibility of accumulated material wearing the crusher parts.

[0012] Optionally, the wear-resistant layer and the fixing column are fixed to the plate body by welding.

[0013] By adopting the above technical scheme, the wear-resistant layer and the fixing column are fixed to the plate body by welding, so that the wear-resistant layer forms a whole with the plate body through the fixing holes and the fixing columns, further increasing the bonding strength between the plate body and the wear-resistant layer, reducing the possibility of the wear-resistant layer falling off the plate body, and reducing the adverse effects on the service life of the grate plate.

[0014] Optionally, the wear-resistant layers include mounting plates relatively arranged on both sides of the end of the plate body, the sides of the mounting plates close to each other are fixedly connected with a plurality of fixing columns adapted to the fixing holes, and the ends of the plate body are provided with fixing components for fixing the mounting plates relatively arranged.

[0015] By adopting the above technical solution, the relatively arranged mounting plates are spliced ​​with each other. At this time, the fixing columns on the mounting plates are relatively arranged and are inserted into the corresponding fixing holes. The mounting plates are fixed to the plate body through the fixing components, thereby facilitating the installation of the wear-resistant layer on the plate body, improving the installation efficiency of the wear-resistant layer, and facilitating the replacement of the worn wear-resistant layer, further reducing the adverse effects on the service life of the grate plate.

[0016] Optionally, the fixing assembly includes a bidirectional lead screw rotatably connected to the plate body and arranged along the width direction of the plate body, the relatively arranged mounting plates are relatively arranged on both sides of the bidirectional lead screw and are threadedly connected to the bidirectional lead screw, and guide rods are fixedly connected on both sides of the end of the plate body, and the ends of the guide rods away from each other pass through the mounting plate and are slidably connected to the mounting plate.

[0017] By adopting the above technical scheme, the relatively arranged mounting plates are placed on both sides of the corresponding plate body ends. At this time, the ends of the guide rods that are away from each other are inserted into the corresponding mounting plates, and the ends of the two-way screws are aligned with the corresponding mounting plates. At this time, the two-way screws are driven to rotate and drive the relatively arranged mounting plates to move toward each other along the length direction of the guide rods until the sides of the mounting plates that are close to each other are pressed against the plate body, and the fixing columns are inserted into the corresponding fixing holes, thereby facilitating the installation of the wear-resistant layer on the plate body, and the two-way screws are not easily separated from the plate body by external forces during use, thereby further improving the stability of the connection between the wear-resistant layer and the plate body and reducing the adverse effects on the service life of the grate plate.

[0018] Optionally, a first nut adapted to the guide rod is provided on one side of the mounting plates that are away from each other, and the first nut is threadedly connected to the guide rod. When the mounting plate is mounted on the plate body, the first nut is pressed against the side wall of the mounting plate.

[0019] By adopting the above technical solution, the mounting plate is installed on the plate body. At this time, the guide rod is fixed by the first nut. At this time, the first nut and the plate body limit the mounting plate, further reducing the possibility of the wear-resistant layer separating from the plate body and reducing the adverse effects on the service life of the grate plate.

[0020] Optionally, a spring connecting the two and arranged along the width direction of the plate body is provided on the side of the relatively arranged mounting plates away from the bidirectional screw, and a receiving groove adapted to the spring is provided on the side of the mounting plates close to each other. The ends of the springs are inserted into the receiving grooves and fixedly connected to the mounting plates, and the springs are always in a stretched state.

[0021] By adopting the above technical solution, when installing the relatively set mounting plates, the mounting plates connected by the driving springs are moved in the direction away from each other. At this time, the springs are stretched. When the fixing columns on the mounting plates are aligned with the corresponding fixing holes, the mounting plates are released. At this time, the springs restore their deformation and drive the mounting plates to move in the direction close to each other, making it convenient for the two-way lead screw to drive the mounting plates to move and press against the plate body. When the mounting plates are installed on the plate body, the springs always tighten the relatively set mounting plates, further reducing the possibility of the wear-resistant layer detaching from the plate body.

[0022] In summary, the present application includes at least one of the following beneficial technical effects:

[0023] 1. The wear-resistant layer is fixed on the plate body. At this time, the fixing columns are all inserted into the corresponding fixing holes, which increases the contact area between the wear-resistant layer and the plate body, thereby increasing the bonding strength between the wear-resistant layer and the plate body. The fixing hole has a small diameter, which further increases the bonding strength between the wear-resistant layer and the plate body, reduces the possibility of the wear-resistant layer falling off the plate body, and reduces the adverse effects on the service life of the grate plate;

[0024] 2. The fixing holes at the ends of the plate body and located on the same side are set in a honeycomb shape, and the bonding strength between the wear-resistant layer and the plate body is further increased through the fixing columns, thereby reducing the possibility of the wear-resistant layer falling off from the plate body and reducing the adverse effects on the service life of the grate plate;

[0025] 3. Place the relatively arranged mounting plates on both sides of the corresponding plate body ends. At this time, the ends of the guide rods that are away from each other are inserted into the corresponding mounting plates, and the ends of the two-way screws are aligned with the corresponding mounting plates. At this time, drive the two-way screws to rotate and drive the relatively arranged mounting plates to move toward each other along the length direction of the guide rods until the sides of the mounting plates that are close to each other are pressed against the plate body, and the fixing columns are inserted into the corresponding fixing holes, so as to facilitate the installation of the wear-resistant layer on the plate body, and the two-way screws are not easily separated from the plate body by external forces during use, further improving the stability of the connection between the wear-resistant layer and the plate body and reducing the adverse effects on the service life of the grate plate.

DETAILED DESCRIPTION

[0031] The present application is further described in detail below in conjunction with the accompanying drawings.

[0032] The embodiment of the present application discloses a honeycomb structure skeleton wear-resistant cladding grate plate.

[0033] Example 1

[0034] Reference Figure 1 and Figure 2A honeycomb structure skeleton wear-resistant cladding grate plate includes a plate body 1. One end of one side of the plate body 1 is provided with a plurality of fixing holes 11 arranged along the width direction of the plate body 1. The fixing holes 11 are arranged in multiple rows along the height direction of the plate body 1. The number of fixing holes 11 in each row is arranged in a honeycomb shape that gradually decreases from top to bottom along the height direction of the plate body 1, and each fixing hole 11 is located on the midline of two adjacent fixing holes 11 in the upper row.

[0035] The other end of the plate body 1 near the fixing hole 11 is also provided with a plurality of fixing holes 11, and the fixing holes 11 at both ends of the plate body 1 are symmetrically arranged along the middle of the length direction of the plate body 1. The other side of the plate body 1 is also provided with a plurality of fixing holes 11, and the fixing holes 11 on both sides of the plate body 1 are arranged oppositely. In the embodiment of the present application, the diameter of the fixing hole 11 is 40 mm. The length of the fixing hole 11 is 30-40 mm, and is set to 30 mm in the embodiment of the present application.

[0036] The upper side of the end of the plate body 1 is sleeved with a wear-resistant layer 2, and the two opposite sides of the wear-resistant layer 2 and the side close to each other are fixedly connected with fixing columns 3 adapted to the fixing holes 11, and the fixing columns 3 are inserted into the corresponding fixing holes 11, and the wear-resistant layer 2 and the fixing columns 3 are fixed to the plate body 1 by welding. The thickness of the wear-resistant layer 2 is 7-10mm, and is set to 10mm in the embodiment of the present application.

[0037] The wear-resistant layer 2 and the fixing column 3 are fixed to the plate body 1 by welding. At this time, the wear-resistant layer 2 forms a whole with the plate body 1 through the fixing holes 11 and the fixing columns 3, which increases the bonding strength between the plate body 1 and the wear-resistant layer 2. At this time, the fixing columns 3 are all inserted into the corresponding fixing holes 11, and the fixing holes 11 at the ends of the plate body 1 and located on the same side are set in a honeycomb shape, which increases the contact area between the wear-resistant layer 2 and the plate body 1, and the diameter of the fixing holes 11 is small, so that the bonding strength between the wear-resistant layer 2 and the plate body 1 is increased, and the possibility of the wear-resistant layer 2 falling off from the plate body 1 is reduced.

[0038] Reference Figure 1 , the ends of the wear-resistant layer 2 on the upper side and close to each other are provided with inclined surfaces inclined toward the side away from the plate body 1 and away from each other, and the angle between the inclined surface and the median line of the plate body 1 set along the height direction of the plate body 1 is 45°. When the plate body 1 is installed on the crusher for use, the inclined surface on the wear-resistant layer 2 allows the material on the crusher to move along the inclined surface, reducing the stacking of materials, thereby reducing the possibility of the accumulated materials wearing the crusher parts.

[0039] The implementation principle of Example 1 is: the wear-resistant layer 2 and the fixing column 3 are welded on the plate body 1, so that the wear-resistant layer 2 and the plate body 1 form a whole, and at this time the fixing columns 3 are all inserted into the corresponding fixing holes 11, and the fixing holes 11 at the ends of the plate body 1 and located on the same side are set to be honeycomb-shaped, and the diameter of the fixing holes 11 is small, which increases the contact area between the wear-resistant layer 2 and the plate body 1, thereby increasing the bonding strength between the wear-resistant layer 2 and the plate body 1 and reducing the possibility of the wear-resistant layer 2 falling off the plate body 1.

[0040] Example 2

[0041] Reference Figure 3 and Figure 4 The difference between this embodiment and the embodiment 1 is that the wear-resistant layer 2 includes mounting plates 21 disposed on both sides of the end of the plate body 1, and the fixing columns 3 are fixedly connected to the side of the mounting plates 21 at the end of the plate body 1 that are close to each other. A plurality of springs 22 disposed along the length direction of the mounting plates 21 and parallel to the width direction of the plate body 1 are disposed between the two mounting plates 21 at the same end of the plate body 1. In the embodiment of the present application, six springs are provided (not shown in the figure).

[0042] The mutually adjacent sides of the oppositely arranged mounting plates 21 are provided with receiving grooves 211 arranged along the length direction of the mounting plates 21 and adapted to the ends of the springs 22. The ends of the springs 22 are inserted into the corresponding receiving grooves 211 and are fixedly connected to the mounting plates 21. The springs 22 are always in a stretched state, and the ends of the plate body 1 are provided with fixing components 4 for fixing the oppositely arranged mounting plates 21.

[0043] The mounting plate 21 connected by the drive spring 22 moves in the direction away from each other. At this time, the spring 22 is stretched. When the fixing column 3 on the mounting plate 21 is aligned with the corresponding fixing hole 11, the mounting plate 21 is released. At this time, the spring 22 restores its deformation and drives the mounting plate 21 to move in the direction of approaching each other, so that the fixing component 4 can install the wear-resistant layer 2 on the plate body 1, and it is also convenient to replace the worn wear-resistant layer 2; and when the mounting plate 21 is installed on the plate body 1, the spring 22 always tightens the relatively arranged mounting plate 21 to reduce the possibility of the wear-resistant layer 2 detaching from the plate body 1.

The bidirectional lead screws 41 located at the same end of the plate body 1 are symmetrically arranged at both ends of the wear-resistant layer 2 away from the inclined surface.

[0045] The ends of the mounting plate 21 away from the inclined surface are sleeved and threadedly connected to the ends of the bidirectional lead screw 41. The end of the plate body 1 is provided with a plurality of guide rods 42 symmetrically arranged on both sides of the plate body 1 and arranged along the width direction of the plate body 1.

A plug-in column 44 arranged along the height direction of the plate body 1 is fixedly connected to the side close to the inclined surface of the plate body 1, and the plug-in column 44 passes through the plug-in hole 213. The diameter of the plug-in hole 213 at the end away from the plate body 1 is larger than the diameter of the plug-in hole 213 at the end close to the plate body 1, and the diameter of the plug-in column 44 is equal to the diameter of the plug-in hole 213 at the end close to the plate body 1.

[0048] A second nut 45 is inserted into one end of the plug hole 213 away from the plate body 1 . The second nut 45 is sleeved on the plug post 44 and threadedly connected with the plug post 44 . When the second nut 45 is fixed to the plug post 44 , the side wall of the second nut 45 is tightly pressed against the side wall of the mounting plate 21 .

At this time, the ends of the guide rods 42 that are away from each other are inserted into the corresponding mounting plates 21, and the ends of the two-way lead screws 41 are aligned with the corresponding mounting plates 21.
