[0001] The utility model belongs to the technical field of roadheader-anchoring machines, and particularly relates to a scraper plate protection device and a roadheader-anchoring machine. Background Technique
[0002] In a mine, when using a roadheader-anchoring machine to cut coal, it is necessary to rely on the rotation of the cutting head to cut coal and use the scraper plate to shovel coal. Due to the uneven structure of the coal seam in the coal mine, during the operation of the cutting head, the force is relatively complex, and the scraper plate is often squeezed and rubbed, resulting in the scraper plate being welded open or damaged, affecting the tunneling progress and service life. Summary of the Invention
[0003] The utility model aims to solve at least one of the technical problems in the related art to some extent. For this purpose, an embodiment of the utility model provides a scraper plate protection device, which can protect the scraper plate and improve the service life of the scraper plate.
[0004] An embodiment of the utility model also provides a roadheader-anchoring machine.
[0005] In the scraper plate protection device of the embodiment of the utility model, the scraper plate includes a scraper plate body and side plates. Side plates are arranged at both edges of the scraper plate body. The scraper plate protection device includes: a first anti-wear plate, and the first anti-wear plate is arranged outside each side plate, and the shape of the first anti-wear plate matches the shape of the side plate; a first connecting member, a first connecting portion is arranged on the first anti-wear plate, a second connecting portion is arranged on the side plate corresponding to the first connecting portion, and the first connecting member is connected to the first connecting portion and the second connecting portion to detachably connect the first anti-wear plate to the side plate.
[0006] It can be understood that by arranging the first anti-wear plates on the side plates on both sides of the scraper plate body, the strength of the scraper plate can be enhanced by arranging the first anti-wear plates. Thus, when the scraper plate is working, the damage of the scraper plate can be reduced, and the side plates of the scraper plate do not directly contact the roadway walls or coal bodies on both sides, and the side plates will not be worn under the protection of the first anti-wear plates. After the first anti-wear plates are worn, new first anti-wear plates can be replaced, improving the service life of the scraper plate.
[0007] In this embodiment, the thickness of the first anti-wear plate is A, and A is 2 cm to 3 cm.
[0008] In this embodiment, anti-wear protrusions are arranged on the side of the first anti-wear plate facing away from the side plate.
[0009] In this embodiment, the side of the first anti-wear plate facing away from the side plate is wavy, and the protrusions of the wavy shape form anti-wear protrusions.
[0010] In this embodiment, the amplitude of the anti-wear protrusion is B, where B is 0.2A to 0.3A, and the wavelength of the anti-wear protrusion is C, where C is 1.7B to 2.2B.
[0011] In this embodiment, the shovel plate protection device further includes a second anti-wear plate, which is arranged on the feeding side of the shovel plate body.
[0012] In this embodiment, the second anti-wear plate includes an upper anti-wear body and a lower anti-wear body. The upper anti-wear body is connected to the lower anti-wear body, and the upper anti-wear body and the lower anti-wear body are arranged at an angle. The second anti-wear plate is clamped at the feeding end of the shovel plate body.
[0013] In this embodiment, a plurality of grooves are arranged at intervals along the width direction of the shovel plate on the upper anti-wear body. A connecting protrusion is formed between two adjacent grooves, and the connecting protrusion is connected to the shovel plate body.
[0014] An excavation and anchoring machine includes a shovel plate, the above-mentioned shovel plate protection device, and a cutting head. The cutting head includes a cutting head body and anti-wear blocks, and the anti-wear blocks are arranged on the side of the cutting head body.
[0015] It can be understood that the protrusion on the side of the cutting head body is prone to wear during the operation of the cutting head. By arranging anti-wear blocks on the cutting head body, the wear of the cutting head body can be reduced, which is beneficial to improving the service life of the cutting head body and can also enhance the strength of the cutting head body.

[0024] Embodiments of the present utility model will be described in detail below. Examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to explain the present utility model and should not be construed as limiting the present utility model.
[0025] In the scraper plate protection device of this embodiment, as Figure 1 and Figure 2 shown, the scraper plate 1 includes a scraper plate body 11 and side plates 12. Side plates 12 are provided at both side edges of the scraper plate body 11. The scraper plate protection device includes a first wear-resistant plate 2 and a first connecting member (not shown in the figure). A first wear-resistant plate 2 is provided outside each side plate 12. The shape of the first wear-resistant plate 2 matches the shape of the side plate 12. A first connecting portion is provided on the first wear-resistant plate 2, and a second connecting portion corresponding to the first connecting portion is provided on the side plate 12. The first connecting member is connected to the first connecting portion and the second connecting portion to detachably connect the first wear-resistant plate 2 to the side plate 12.
[0026] Specifically, the shape of the first wear-resistant plate 2 matches the shape of the side plate 12.
[0027] For example, the first connecting member can be a bolt, and both the first connecting portion and the second connecting portion are connecting holes. The bolt passes through the first connecting hole and the second connecting hole to fix the first wear-resistant plate 2 to the side plate 12. A plurality of first connecting members are provided to stably connect the first wear-resistant plate 2 and the side plate 12. Of course, the first connecting member, the first connecting portion, and the second connecting portion can also be set in other forms, which will not be limited here.
[0028] The first wear-resistant plate can be a steel plate, which has good wear resistance and high strength. Of course, the first wear-resistant plate can also be made of other materials, which will not be limited here.
[0029] It can be understood that by providing the first wear-resistant plates 2 on the side plates 12 on both sides of the scraper plate body 11, the strength of the scraper plate 1 can be enhanced by providing the first wear-resistant plates 2. Thus, when the scraper plate 1 is working, the breakage of the scraper plate 1 can be reduced, and the side plates 12 of the scraper plate 1 do not directly contact the roadway walls or coal bodies on both sides and will not cause wear to the side plates 12 under the protection of the first wear-resistant plates 2. After the first wear-resistant plates 2 are worn, new first wear-resistant plates 2 can be replaced, improving the service life of the scraper plate 1.
[0030] In this embodiment, the thickness of the first wear-resistant plate 2 is A, and A is 2 cm to 3 cm.
[0031] For example, the thickness A of the first wear-resistant plate 2 can be 2 cm, 2.1 cm, 2.2 cm, 2.3 cm, 2.5 cm, 2.6 cm, 2.8 cm, 3 cm, etc., without limitation here. If the thickness of the first wear-resistant plate 2 is too thin, the wear-resistant effect is poor and the strength is low, and it needs to be replaced frequently. If the thickness of the first wear-resistant plate 2 is too thick, the weight is heavy and the occupied space is large, which will affect the use of the shovel plate 1.
[0032] In this embodiment, by setting the thickness of the first wear-resistant plate 2 between 2 cm and 3 cm, the strength of the shovel plate 1 can be enhanced, and the first wear-resistant plate 2 has a certain wear resistance and does not need to be replaced frequently.
[0033] In this embodiment, a wear-resistant protrusion (not shown in the figure) is provided on the side of the first wear-resistant plate 2 facing away from the side plate 12.
[0034] For example, the wear-resistant protrusion is hemispherical, which can reduce the friction of the wear-resistant protrusion and is beneficial to the movement of the shovel plate 1.
[0035] It can be understood that by providing a wear-resistant protrusion on the side of the first wear-resistant plate 2 facing away from the side plate 12, when the first wear-resistant plate 2 is worn, the wear-resistant protrusion is worn first, which can improve the wear resistance of the wear-resistant plate.
[0036] In this embodiment, the side of the first wear-resistant plate 2 facing away from the side plate 12 is wavy, and the protruding part of the wave shape forms a wear-resistant protrusion.
[0037] Specifically, the wave shape on the surface of the first wear-resistant plate 2 extends along the moving direction of the shovel plate 1, which can reduce the resistance when the wear-resistant protrusion moves and contacts the roadway wall or the coal body.
[0038] It should be noted that by setting the surface of the first wear-resistant plate 2 to be wavy, wear-resistant protrusions are formed in the protruding parts, and grooves 311 are formed in the concave parts. The concave parts will be filled with coal powder, which has a lubricating effect, thereby reducing friction and reducing the wear of the first wear-resistant plate 2. At the same time, the wear-resistant protrusions have the function of reinforcing ribs, which is beneficial to improving the service life of the first wear-resistant plate 2.
[0039] In this embodiment, the amplitude of the wear-resistant protrusion is B, B is 0.2A to 0.3A, and the wavelength of the wear-resistant protrusion is C, C is 1.7B to 2.2B.
[0040] For example, B is 0.2A, 0.22A, 0.25A, 0.27A, or 0.3A, etc. If the amplitude of the wear-resistant protrusion is small, the wear-resistant effect is poor. If it is too large, the overall thickness will be thinned, which is not conducive to improving the strength of the first wear-resistant plate 2. The wavelength of the wear-resistant protrusion can be 1.7, 1.8B, 1.9B, 2.0B, 2.1B, or 2.2B.
[0041] In this embodiment, by setting the amplitude of the anti-wear protrusion to 0.2A - 0.3A and the wavelength of the anti-wear protrusion to 1.7B - 2.2B, the wear resistance of the first anti-wear plate 2 can be improved while reducing the frictional force.
[0042] In this embodiment, as Figure 1 shown, the shovel plate protection device further includes a second anti-wear plate 3, and the second anti-wear plate 3 is arranged on the feeding side of the shovel plate body 11.
[0043] It can be understood that when the shovel plate 1 is working, the shovel plate body 11 is conveyed towards the rear end of the shovel plate body 11 through the feeding side of the shovel plate body 11. The frictional force on the feeding side of the shovel plate body 11 is relatively large. Therefore, by arranging the second anti-wear plate 3 on the feeding side of the shovel plate body 11, it is beneficial to improve the service life of the shovel plate body 11.
[0044] In this embodiment, the second anti-wear plate 3 includes an upper anti-wear body 31 and a lower anti-wear body 32. The upper anti-wear body 31 is connected to the lower anti-wear body 32, and the upper anti-wear body 31 and the lower anti-wear body 32 are arranged at an angle. The second anti-wear plate 3 is clamped at the feeding end of the shovel plate body 11.
[0045] For example, both the upper anti-wear body 31 and the lower anti-wear body 32 are rubber anti-wear bodies, which can make the anti-wear effect of the second anti-wear plate better, and at the same time make the shoveling effect of the shovel plate better, reducing the remaining coal. The upper anti-wear body 31 and the lower anti-wear body 32 can be integrally formed, which can improve the strength of the second anti-wear plate 3. Of course, the upper anti-wear body 31 and the lower anti-wear body 32 can also be separately formed, which is not limited here. Multiple second anti-wear plates 3 can be arranged. The multiple second anti-wear plates 3 are arranged in sequence along the width direction of the feeding side of the shovel plate body 11. When a certain second anti-wear plate 3 is worn, only the worn second anti-wear plate 3 needs to be replaced, without the need for overall replacement, which can save costs and reduce labor intensity.
[0046] It can be understood that the second anti-wear plate 3 includes an upper anti-wear body 31 and a lower anti-wear body 32. The upper anti-wear body 31 is arranged on the upper surface of the shovel plate body 11, and the lower anti-wear body 32 is arranged on the lower surface of the shovel plate body 11, so as to protect both the upper and lower surfaces of the feeding side of the shovel plate body 11, and the protection effect is better.
[0047] In this embodiment, as Figure 1 and Figure 3 shown, a plurality of grooves 311 are arranged at intervals along the width direction of the shovel plate 1 on the upper anti-wear body 31. A connecting protrusion 312 is formed between two adjacent grooves 311, and the connecting protrusion 312 is connected to the shovel plate body 11.
[0048] For example, holes are arranged on the connecting protrusion 312, and the connecting protrusion 312 and the shovel plate body 11 can be connected by bolts.
[0049] By providing a groove 311 on the upper anti-wear body 31 and forming a connecting protrusion 312 between two adjacent grooves 311, the upper anti-wear body 31 and the shovel plate body 11 can be more closely fitted, reducing the entry of pulverized coal dust between the upper anti-wear body 31 and the shovel plate body 11, and thus reducing the friction between the second anti-wear plate 3 and the shovel plate body 11, which is beneficial to improving the service life of the second anti-wear plate 3 and the shovel plate body 11.
[0050] In the roadheader of this embodiment, it includes a shovel plate 1, the above-mentioned shovel plate protection device and a cutting head (not shown in the figure). The cutting head includes a cutting head body and anti-wear blocks, and the anti-wear blocks are arranged on the side of the cutting head body.
[0051] The anti-wear block can be a steel block, which has good wear resistance and high strength. Of course, the anti-wear block can also be set to other materials, which is not limited here.
[0052] It can be understood that the protrusion on the side of the cutting head body is prone to wear during the operation of the cutting head. By providing anti-wear blocks on the cutting head body, the wear of the cutting head body can be reduced, which is beneficial to improving the service life of the cutting head body, and at the same time, the strength of the cutting head body can be enhanced.
[0053] In this embodiment, multiple anti-wear blocks are provided, and the multiple anti-wear blocks are respectively welded to the cutting head body.
[0054] Specifically, the number of anti-wear blocks can be set according to the structure of the cutting head body, which is not limited here.
[0055] It can be understood that by welding the anti-wear blocks to the cutting head body, the connection between the anti-wear blocks and the cutting head body can be facilitated, and at the same time, the strength of the cutting head body can be avoided from being reduced by connection methods such as drilling.
[0056] In this embodiment, by providing the first anti-wear plates 2 on both side plates of the shovel plate body 11 and providing the second anti-wear plate 3 on the feeding side of the shovel plate body 11, by providing the first anti-wear plates 2 and the second anti-wear plate 3, the strength and wear resistance of the shovel plate can be enhanced, and the anti-wear blocks and strength are provided on the cutting head, which is beneficial to improving the wear resistance of the cutting head, and thus beneficial to improving the service life of the roadheader.
