Description

Technical Field

[0001] This invention relates to the field of transfer machine technology, and in particular to a transfer machine groove and a transfer machine. Background Technology

[0002] Scraper transfer conveyors are used in the transport roadways of large fully mechanized mining faces that are characterized by high efficiency and high output. The two ends of the scraper transfer conveyor are connected to the conveyor and the tail of the belt conveyor at the working face, respectively, so that the coal transported by the scraper conveyor at the working face can be raised from the bottom of the roadway and transferred to the belt conveyor. Once the scraper transfer conveyor malfunctions, it will affect the continuity of its operation and have a significant impact on coal mine production.

[0003] The transfer chute is an important component of the scraper transfer conveyor, used to lift coal output from the lower scraper conveyor onto the higher belt conveyor. The middle plate and bottom plate are key components of the chute. Because the chute is located at the inflection point between inclined and straight transport, the middle chain runs closely against the middle plate of the chute during the operation of the scraper chain, causing wear on the middle plate and reducing the service life of the chute, which directly affects the production efficiency of the working face and the coal output. Summary of the Invention

[0004] This invention provides a transfer machine chute and a transfer machine to solve the defects of easy wear and high replacement frequency of the middle plate in the prior art, and to improve the service life of the transfer machine chute.

The middle plate is disposed between the first side plate and the second side plate. The middle plate includes a plurality of wear-resistant plates. Both ends of each wear-resistant plate are detachably connected to the first side plate and the second side plate. A concave-convex connection structure is provided between two adjacent wear-resistant plates. The two wear-resistant plates are adapted to be slidably connected through the concave-convex connection structure. The surface of each wear-resistant plate is provided with a wear-resistant coating.

[0012] Adjustment holes are provided at the first end of the wear-resistant plate. Each adjustment hole extends in a direction perpendicular to the first side plate. The first connecting plate is connected to the first end of the wear-resistant plate by bolts passing through the first connecting hole and the adjustment hole.

[0013] Preferably, in the transfer machine groove provided by the present invention, the second connecting structure includes:

[0014] The second connecting plate is fixedly connected to the outside of the second side plate;

[0033] To make the objectives, technical solutions, and advantages of this invention clearer, the technical solutions of this invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this invention. All other embodiments obtained by those skilled in the art based on the embodiments of this invention without creative effort are within the scope of protection of this invention.

[0034] The following is combined with Figures 1 to 7 This invention describes a transfer machine groove and a transfer machine provided in an embodiment of the present invention.

[0035] This embodiment provides a transfer machine chute, including a middle plate, a first side plate 1 and a second side plate 2, and a top plate and a bottom plate respectively connected to the upper and lower ends of the first side plate 1 and the second side plate 2. The middle plate is disposed between the first side plate 1 and the second side plate 2. The middle plate includes a plurality of wear-resistant plates 3. Both ends of each wear-resistant plate 3 are detachably connected to the first side plate 1 and the second side plate 2, and the surface of each wear-resistant plate 3 is provided with a wear-resistant coating.

[0036] As can be seen from the above scheme, compared with the prior art, the present invention sets the middle plate to be composed of multiple wear-resistant plates 3, and each wear-resistant plate 3 is provided with a wear-resistant coating to reduce the degree of wear and improve the service life of the middle plate. Since the middle plate adopts a split and detachable structure, when any wear-resistant plate 3 is worn, only the current wear-resistant plate 3 is removed from the groove and replaced, which facilitates maintenance and improves the utilization rate of materials, avoiding the need to replace the entire middle plate.

[0037] Preferably, each wear-resistant plate 3 includes a substrate layer and a wear-resistant coating disposed on the surface. For example, the wear-resistant coating has a thickness of 5-10 mm, the substrate has a thickness of 20 mm, and the wear-resistant coating is made of a wear-resistant cladding material, which can be an alloy powder used to improve the wear resistance of the material surface, such as nickel-based self-fluxing alloy powder (Ni45 nickel-based alloy powder) or sparkless welding alloy powder for coal cutting teeth.

[0038] In this embodiment, the first side plate 1 and the second side plate 2 are provided with insertion holes opposite to each other, and the two ends of the wear-resistant plate 3 are connected to the first side plate 1 and the second side plate 2 respectively through the insertion holes.

[0039] like Figure 1As described above, both the first side plate 1 and the second side plate 2 have insertion holes along their length direction. The insertion holes are adapted to the middle plate. Each wear-resistant plate 3 can be inserted into the groove from the insertion hole from the outside of the first side plate 1 or the second side plate 2. The two ends of the wear-resistant plate 3 are located outside the two insertion holes respectively. The two ends of the wear-resistant plate 3 are detachably connected to the first side plate 1 and the second side plate 2 respectively.

[0040] In this embodiment, a first connecting structure is provided on the outer side of the first side plate 1, and the first side plate 1 is connected to the wear-resistant plate 3 through the first connecting structure; a second connecting structure is provided on the outer side of the second side plate 2, and the second side plate 2 is connected to the wear-resistant plate 3 through the second connecting structure.

[0041] Specifically, the first connecting structure includes: a first connecting plate 4, first connecting holes, and adjusting holes 5. The first connecting plate 4 is fixedly connected to the outside of the first side plate 1, possibly by welding. Multiple first connecting holes are provided on the first connecting plate 4, and multiple adjusting holes 5 are provided at the first end of the wear-resistant plate 3. Each adjusting hole 5 extends in a direction perpendicular to the first side plate 1 and can be a strip-shaped or oblong hole. Bolts are passed through the first connecting holes and adjusting holes 5 to connect the first connecting plate 4 to the first end of the wear-resistant plate 3.

[0042] With this configuration, by setting an adjustment hole 5 at the first end of the wear-resistant plate 3, when the groove expands and deforms, the first side plate 1, the connecting plate and the bolt can move relative to the wear-resistant plate 3 along the length direction of the adjustment hole 5. That is, the adjustment hole 5 can provide deformation compensation to both sides of the groove, so that the wear-resistant plate 3 always maintains a reliable connection with the side plates, and avoids the shear force generated by expansion and deformation acting on the middle plate, which would cause the groove to crack and be damaged.

[0043] like Figure 2 As shown, the first connecting plate 4 is located below the insertion hole and is fixedly connected to the outside of the first side plate 1 by welding. Multiple spaced first connecting holes are provided along the length direction of the first connecting plate 4. The lower surface of the first end of the wear-resistant plate 3 is placed on the first connecting plate 4. Multiple adjustment holes 5 are provided on each wear-resistant plate 3. The number of adjustment holes 5 is the same as the number of first connecting holes and they correspond one-to-one. The adjustment holes 5 are strip-shaped holes. The length direction of the adjustment holes 5 is perpendicular to the first side plate 1. The first end of the wear-resistant plate 3 is connected to the first connecting plate 4 by bolts passing through the adjustment holes 5 and the first connecting holes.

[0044] Furthermore, in order to improve the connection strength between the first connecting plate 4 and the first side plate 1, and thus improve the overall structural strength, a plurality of stiffening plates 6 are provided between the surface of the first connecting plate away from the wear-resistant plate 3 and the outer side of the first side plate 1. The two adjacent sides of the stiffening plates 6 are respectively connected to the first connecting plate and the first side plate 1 by welding.

[0045] In another embodiment, the first connecting plate 4 can be disposed above the insertion hole and is also fixedly connected to the outside of the first side plate 1 by welding. Multiple spaced first connecting holes are provided along the length direction of the first connecting plate 4. Multiple adjustment holes 5 are provided on each wear-resistant plate 3. The number of adjustment holes 5 is the same as the number of first connecting holes and they correspond one-to-one. The adjustment holes 5 are strip-shaped holes. The length direction of the adjustment holes 5 is perpendicular to the first side plate 1. The upper surface of the first end of the wear-resistant plate 3 is attached to the lower surface of the first connecting plate 4. The first end of the wear-resistant plate 3 is connected to the first connecting plate 4 by bolts passing through the adjustment holes 5 and the first connecting holes.

[0046] In a further embodiment, a first positioning ear plate 7 is connected to the outer side of the first side plate 1. The first positioning ear plate 7 is fixed to the outer side of the first side plate 1 by welding. The first positioning ear plate 7 and the first connecting plate 4 are respectively set on the upper and lower sides of the insertion hole. The first positioning ear plate 7 is provided with a first positioning hole corresponding to the adjustment hole 5. The first positioning ear plate 7, the first end of the wear-resistant plate 3 and the first connecting plate 4 are connected by bolts passing through the first positioning hole, the first connecting hole and the adjustment hole 5 in sequence.

[0047] With this configuration, by setting the first positioning ear plate 7 and the first connecting plate 4 on the upper and lower sides of the insertion hole respectively, the wear-resistant plate 3 is inserted into the protrusion through the insertion hole, so that the first positioning ear plate 7 and the first connecting plate 4 are fixedly connected to the upper and lower surfaces of the first end of the wear-resistant plate 3 respectively, thereby improving the connection stability between the wear-resistant plate 3 and the first side plate 1; and this structure is easy to disassemble, so that when the wear-resistant plate 3 needs to be replaced, the first end of the wear-resistant plate 3 can be quickly disconnected from the first connecting plate 4 and the first positioning ear plate 7.

[0048] like Figures 2 to 4 As shown, the first connecting plate 4 is located below the insertion hole. The length of the first connecting plate 4 is not less than the length of the insertion hole, ensuring that all wear-resistant plates 3 can be connected to the first connecting plate 4. The total length of the middle plate formed by splicing all wear-resistant plates 3 is adapted to the length of the insertion hole. The first positioning ear plate 7 is located above the insertion hole. It can be the same number as the wear-resistant plates 3 and correspond one-to-one. The first positioning ear plate 7 is located in the middle position of each wear-resistant plate 3. For example, the first positioning ear plate 7 is L-shaped and includes two adjacent connecting surfaces. One connecting surface of the first positioning ear plate 7 is welded to the outer side of the first side plate 1, and the other connecting surface of the first positioning ear plate 7 contacts the upper surface of the wear-resistant plate 3. Then, the first positioning ear plate 7, the first end of the wear-resistant plate 3 and the first connecting plate 4 are connected together by bolts or pins passing through the first positioning hole, the first connecting hole and the adjustment hole 5 in sequence.

[0049] In one embodiment, the first positioning ear plate 7 includes a base plate 71 and a vertical plate 72, which are connected to form an L-shape. The base plate 71 has a first positioning hole, and the vertical plate 72 is used for welding to the outer side of the first side plate 1. Figure 3 As shown, the upright plate 72 can be a triangular prism, specifically a right-angled triangular prism. One right-angled face (side face) of the upright plate 72 is connected to the outer side of the first side plate 1, and the other right-angled face (bottom face) of the upright plate 72 is connected to the base plate 71. Thus, the inclined surface is located between the first side plate 1 and the base plate 71. By adopting a triangular connection structure between the base plate 71, the first side plate 1 and the upright plate 72, the connection stability and reliability between the base plate 71 and the first side plate 1 are further improved.

[0050] In this embodiment, the second connecting structure includes a second connecting plate 8, second connecting holes, and fixing holes 9. The second connecting plate 8 is fixedly connected to the outer side of the second side plate 2 by welding. Multiple second connecting holes are provided on the second connecting plate 8. Multiple fixing holes 9 are provided at the second end of the wear-resistant plate 3. Bolts are passed through the second connecting holes and fixing holes 9 to fix the second connecting plate 8 to the second end of the wear-resistant plate 3.

[0051] like Figure 2 As shown, the second connecting plate 8 is positioned below the insertion hole and is fixedly connected to the outer side of the second side plate 2 by welding. Multiple spaced second connecting holes are provided along the length of the second connecting plate 8. The lower surface of the second end of the wear-resistant plate 3 rests on the second connecting plate 8. Multiple fixing holes 9 are provided on each wear-resistant plate 3. The number of fixing holes 9 and the number of second connecting holes are the same and they correspond one-to-one. The fixing holes 9 and the second connecting holes also have the same shape and size. Bolts are passed through the fixing holes 9 and the second connecting holes to connect the second end of the wear-resistant plate 3 to the second connecting plate 8. Alternatively, the second connecting plate 8 can be positioned above the insertion hole and welded to the outer side of the second side plate 2, so that the upper surface of the second end of the wear-resistant plate 3 is flush with the lower surface of the second connecting plate 8. Bolts are then passed through the fixing holes 9 and the second connecting holes to connect the second end of the wear-resistant plate 3 to the second connecting plate 8.

[0052] This configuration allows for the fixed connection between the second end of each wear-resistant plate 3 and the second connecting plate 8.

[0053] like Figure 2 As shown, a second positioning ear plate 10 is connected to the outer side of the second side plate 2. The second positioning ear plate 10 and the second connecting plate 8 are respectively set on the upper and lower sides of the insertion hole. The second positioning ear plate 10 is provided with a second positioning hole corresponding to the fixing hole 9. The second positioning ear plate 10, the second end of the wear-resistant plate 3 and the second connecting plate 8 are connected by bolts passing through the second positioning hole, the second connecting hole and the fixing hole 9 in sequence.

[0054] With this configuration, by setting a second positioning ear plate 10 and a second connecting plate 8 on the upper and lower sides of the insertion hole respectively, the wear-resistant plate 3 is inserted into the groove through the insertion hole, so that the second positioning ear plate 10 and the second connecting plate 8 are fixedly connected to the upper and lower surfaces of the second end of the wear-resistant plate 3 respectively, which improves the connection stability between the wear-resistant plate 3 and the second side plate 2. Moreover, this structure is easy to disassemble. When it is necessary to replace the wear-resistant plate 3, the second end of the wear-resistant plate 3 can be quickly disconnected from the second connecting plate 8 and the second positioning ear plate 10, and then the wear-resistant plate 3 can be taken out from the groove through the insertion hole.

[0055] like Figure 2 As shown, the second connecting plate 8 is located below the insertion hole. The length of the second connecting plate 8 is not less than the length of the insertion hole, ensuring that all wear-resistant plates 3 can be connected to the second connecting plate 8. The total length of the middle plate formed by splicing all wear-resistant plates 3 is adapted to the length of the insertion hole. The second positioning ear plate 10 is located above the insertion hole. It can be the same number as the wear-resistant plates 3 and correspond one-to-one. The second positioning ear plate 10 is located in the middle position of each wear-resistant plate 3. Then, bolts or pins are used to pass through the second positioning hole, the second connecting hole and the fixing hole 9 in sequence to connect the second positioning ear plate 10, the second end of the wear-resistant plate 3 and the second connecting plate 8 together. The second positioning ear plate 10 can be the same structure as the first positioning ear plate 7, and also includes the base plate 71 and the upright plate 72.

[0056] In this embodiment, a concave-convex connection structure is provided between two adjacent wear-resistant plates 3. The concave-convex connection structure realizes the sliding connection between the two adjacent wear-resistant plates 3. Specifically, the concave-convex connection structure can be provided on the relative connection surfaces of two adjacent wear-resistant plates 3. For example, a protrusion is provided on one of the connection surfaces, and the length of the protrusion is the length of the wear-resistant plate 3 from the first end to the second end; a groove is provided on the other connection surface, and the length of the groove is also the length of the wear-resistant plate 3 from the first end to the second end. Thus, when it is necessary to remove any wear-resistant plate 3 from the middle plate, the matching relationship between the groove and the protrusion can be used to release the connection relationship between the two ends of the wear-resistant plate 3, and then the wear-resistant plate 3 can be pulled out from the first end or the second end.

[0057] This design, through the concave-convex connection structure, helps improve the connection stability between two adjacent wear-resistant plates 3. After multiple wear-resistant plates 3 are assembled into a middle plate, it can prevent any wear-resistant plate 3 from moving or shaking at the connection point during operation, ensuring the stability and reliability of the overall structure. Furthermore, since the concave-convex fit connection between two adjacent wear-resistant plates 3 is adopted, it also facilitates the assembly and disassembly of a single wear-resistant plate 3. The wear-resistant plate 3 can be slid out along the length of the groove or protrusion, or the wear-resistant plate 3 to be installed can be inserted between the first side plate 1 and the second side plate 2 through the groove and protrusion fit of one end of the wear-resistant plate 3 to be installed. This allows the concave-convex connection structure to also play a guiding and positioning role.

[0058] like Figure 6 and Figure 7 As shown, the concave-convex connection structure can be a groove and a protrusion set in the middle of the connection surface of the wear-resistant plate 3, or it can be a stepped structure set on the connection surface.

[0059] This invention also provides a transfer machine, including the transfer machine groove described above. Because the transfer machine uses the aforementioned transfer machine groove, it has the following advantages:

[0060] 1. The middle plate in this transfer machine adopts a split and detachable structure. Each wear plate 3 can be replaced after wear, eliminating the drawback of the existing technology that requires overall maintenance of the convex groove and replacement of the entire middle plate; and when one wear plate 3 is severely worn, it can be swapped with wear plates 3 in other less worn parts to achieve the same service life.

[0061] 2. Individual wear-resistant plates 3 are lightweight, easy to assemble, and easy to process;

[0062] 3. Wear-resistant plate 3 is coated with a wear-resistant coating to increase its wear resistance and reduce replacement frequency and cost;

[0063] 4. An adjustment hole 5 is provided at one end of the wear-resistant plate 3, which can provide deformation compensation to both sides of the groove, so that the wear-resistant plate 3 always maintains a reliable connection with the side plates and avoids the shear force generated by expansion deformation acting on the middle plate, causing the groove to crack and be damaged.

[0064] 5. The concave-convex fit between two adjacent wear-resistant plates 3 is conducive to improving the connection stability between the two adjacent wear-resistant plates 3, and can also play a positioning and guiding role when a single wear-resistant plate 3 is disassembled and assembled.

[0065] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, and not to limit them; although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.
