Description

Technical Field

[0001] This utility model belongs to the field of lip plate protection technology, specifically a wear-resistant double-lobed grab lip plate protection device. Background Technology

[0002] Double-lobed grabs are specialized tools used in construction machinery to grab bulk materials. The lip plate is a wear-resistant part of the grab that directly contacts the material. It is usually located at the cutting edge at the front of the grab and is made of high-strength alloy steel by casting or welding. The replacement cost of the lip plate is relatively high, so a protective plate is often needed to protect the lip plate.

[0003] The existing double-lobed grab bucket lip plate protective plate is installed on the lip plate by fixing the protective plate on the lip plate with high-strength bolts and fastening nuts. The protective plate covers the lip plate and replaces the lip plate in generating friction and collision with the object, thereby achieving the protection of the lip plate.

[0004] However, because the double-lobed grab needs to open and close continuously during operation, the side guards may collide repeatedly when closing, causing severe wear or deformation of the guards and affecting their service life. Utility Model Content

[0026] The technical solution of this patent will be further described in detail below with reference to specific embodiments.

[0027] like Figure 1-5As shown, this utility model provides a technical solution: a wear-resistant double-lobed grab lip plate protective device 3, including a plate body 1, a partition device 2 provided on one side of the plate body 1, the partition device 2 including a rectangular groove 21 opened on the plate body 1, a circular hole 22 opened on one side of the plate body 1, the inner wall of the circular hole 22 being connected to the inner wall of the rectangular groove 21, a rectangular cylinder 24 being slidably connected to the inner wall of the rectangular groove 21, a first screw 25 being threadedly connected to the inner wall of the rectangular cylinder 24, the surface size and shape of the first screw 25 being adapted to the size and shape of the inner wall of the circular hole 22, a slider 26 being fixedly connected to the inner wall of the rectangular cylinder 24, and a rectangular block 29 being slidably connected to the inner wall of the rectangular cylinder 24, wherein the slider 26 is placed in the groove of the rectangular block 29 for limiting its position, and a wear-resistant plate 210 being fixedly connected to one side of the rectangular block 29, wherein the wear-resistant plate 210 is made of high manganese alloy. By setting the partition device 2, manual movement is first... The moving rectangular cylinder 24 drives the rectangular block 29 and the wear-resistant plate 210 to move. When the rectangular cylinder 24 moves to the position where it is fully inserted into the rectangular groove 21, the inner wall of the hole on the rectangular cylinder 24 coincides with the inner wall of the circular hole 22. At this time, the first screw 25 is screwed into the circular hole 22 and the rectangular cylinder 24 to fix the rectangular cylinder 24, thus completing the assembly and fixation between the wear-resistant plate 210 and the plate body 1. When the plate body 1 collides with another plate body 1, the two wear-resistant plates 210 on the two plate bodies 1 separate the two plate bodies 1, replacing the collision between the plate bodies 1, thus achieving the separation and protection of the plate bodies 1. At the same time, the wear-resistant plate 210 is made of high manganese alloy, which has high toughness and wear resistance, reducing the continuous collision between the plate bodies 1 on both sides when they follow the grab bucket and the lip plate to move together, which would cause serious wear or deformation of the plate bodies 1, thus improving the service life and wear resistance of the plate bodies 1.

[0028] Specifically, such as Figure 2 , Figure 3 and Figure 4 As shown, a storage groove 23 is provided on the side of the plate 1 near the circular hole 22. The inner wall of the storage groove 23 is larger than the first screw 25. By setting the storage groove 23, the nut of the first screw 25 can be completely inserted into the storage groove 23 for storage, reducing the situation where the nut of the first screw 25 is higher than the surface of the plate 1 and is easily damaged by material impact, affecting normal use. The wear-resistant plate 210 has multiple reinforcing ribs 211 inside, and the reinforcing ribs 211 are made of tungsten carbide hard alloy. By setting the reinforcing ribs 211, the strength and wear resistance of the wear-resistant plate 210 can be further improved, and the deformation of the wear-resistant block after being subjected to force can be reduced.

[0029] Specifically, such as Figure 2 , Figure 3 and Figure 4As shown, a rubber pad 27 is fixedly connected to the inner wall of the rectangular tube 24. The surface of the rubber pad 27 is in contact with the surface of the rectangular block 29. When the wear-resistant block is subjected to force, the rubber pad 27 pushes the rectangular block 29 to slide along the inside of the rectangular tube 24 and squeezes the rubber pad 27, causing the rubber pad 27 to deform under force. The deformation absorbs kinetic energy and reduces the impact force brought by the rectangular block 29, providing a certain buffering effect for the wear-resistant block. At the same time, it separates the rectangular block 29 from the inner wall of the rectangular tube 24, reducing the impact damage caused by the wear-resistant plate 210 to the rectangular tube 24. A baffle plate 28 is fixedly connected to one side of the rectangular tube 24. The surface of the baffle plate 28 is larger than the inner wall of the rectangular groove 21. By setting the baffle plate 28, the baffle plate 28 can intercept the wear-resistant plate 210 during the movement, preventing the wear-resistant plate 210 from contacting the surface of the plate 1, further improving the protection effect of the plate 1.

[0030] Specifically, such as Figure 4 and 5 As shown, a protective device 3 is provided on the side of the plate 1 near the connecting hole. The protective device 3 includes a protective cover 31. A circular hole plate 32 is fixedly connected to one side of the protective cover 31. A second screw 33 is provided inside the circular hole plate 32. A threaded groove 35 is opened on the side of the plate 1 near the connecting hole. The surface of the second screw 33 is threadedly connected to the inner wall of the threaded groove 35. By setting the protective device 3, when the plate 1 is installed on the lip plate by bolts and nuts, the nut of the bolt is higher than the surface of the plate 1. At this time, the protective cover 31 is manually put on the nut of the bolt, so that the protective cover 31 is flush with the surface of the plate 1. The fit is such that the inner wall of the circular hole plate 32 coincides with the inner wall of the threaded groove 35. At this time, the second screw 33 is screwed into the circular hole plate 32 and the threaded groove 35 to fix the protective cover 31. The protective cover 31 completely covers the bolts and intercepts external materials, thereby protecting the bolts used in the mounting plate 1. This reduces the direct collision between external materials and the protruding part of the bolts used in the mounting plate 1, which could cause deformation and damage to the bolts and affect the convenience of maintenance and replacement of the plate 1 in the future. This improves the safety and lifespan of the bolts used in the mounting plate 1.

[0031] Specifically, such as Figure 4 and Figure 5 As shown, a circular ring 34 is fixedly connected to one side of the circular plate 32, and the second screw 33 is placed inside the circular ring 34. By setting the circular ring 34, the second screw 33 can be wrapped inside, separating the material from the second screw 33 and preventing the material from damaging the second screw 33.

[0032] The working principle of this utility model is as follows:

[0033] S1. First, manually move the rectangular tube 24 to move the rectangular block 29 and the wear-resistant plate 210. When the rectangular tube 24 moves to the position where it is fully inserted into the rectangular groove 21, the inner wall of the hole on the rectangular tube 24 coincides with the inner wall of the circular hole 22. At this time, use a tool to screw the first screw 25 into the circular hole 22 and the rectangular tube 24 to fix the rectangular tube 24, thus completing the assembly and fixation between the wear-resistant plate 210 and the plate 1. When the plate 1 collides with another plate 1, the two wear-resistant plates 210 on the two plates 1 separate the two plates 1 and replace the plate 1 in the collision wear, thus achieving the separation and protection of the plate 1. At the same time, the wear-resistant plate 210 is made of high manganese alloy, which has high toughness and wear resistance.

[0034] S2. When plate 1 is installed on the lip plate with bolts and nuts, the bolt nuts are positioned above the surface of plate 1. At this time, the protective cover 31 is manually placed on the bolt nuts, so that the protective cover 31 fits against the surface of plate 1, and the inner wall of the circular hole plate 32 coincides with the inner wall of the threaded groove 35. Then, the second screw 33 is screwed into the circular hole plate 32 and the threaded groove 35 to fix the protective cover 31, so that the protective cover 31 completely covers the bolts and intercepts external materials, thereby protecting the bolts used to install plate 1.
