[0028] Reference Figure 1-4 As shown, this embodiment discloses a fork ring for an excavator, comprising a shell 1, with through holes 4 on both sides of the shell 1, bolts 5 inserted into the through holes 4 on both sides of the shell 1, nuts 6 threadedly inserted into one side of the bolts 5, and blocking devices 2 provided on both sides of one side of the shell 1.

[0029] Reference Figure 1-4As shown, this embodiment discloses a blocking device 2 including a placement plate 21, one side of which is fixedly connected to the housing 1. A through-hole 22 is formed in one side of the placement plate 21, and a blocking block 23 is inserted into the through-hole 22 on one side of the placement plate 21. The size of the blocking block 23 matches the size of the nut 6 and the bolt 5. A magnet 24 is fixedly connected to one side of the placement plate 21, and an iron sheet 25 is fixedly connected to one side of the blocking block 23. The magnet 24 and the iron sheet 25 are magnetically attracted to each other. When using the guide wheel fork ring of the excavator, a bolt 5 and a nut 6 are used on the through-hole 4 of the housing 1 to fix the fork ring to the pull rod. After the bolt 5 and the nut 6 are fixed to the housing 1, the two blocking plates can be moved so that the blocking plates are inserted into the through holes 22 of the plates 21 on both sides of the housing 1, and then the blocking plates are on the side of the bolt 5 and the nut 6 away from the housing 1. At this time, the magnet 24 and the iron sheet 25 on the blocking block 23 are adsorbed, and then the position of the blocking block 23 is fixed. By using the blocking device 2, the position of the nut 6 and the bolt 5 can be limited to avoid vibration of the bolt 5 and the nut 6, which then causes the nut 6 and the bolt 5 to move and finally separate from the two, thereby improving the use effect of the fork ring.

[0030] Reference Figure 1-4 As shown, this embodiment discloses an extension plate 26 fixedly connected to one side of the blocking block 23. The size of the extension plate 26 matches the size of the blocking block 23. When using the blocking block 23, the extension plate 26 can increase the contact area between the operator and the blocking block 23, making it easier for the operator to move the blocking block 23. A plurality of anti-slip blocks 27 are fixedly connected to one side of the extension plate 26. The anti-slip blocks 27 increase the friction between the extension plate 26 and the operator, thereby improving the use of the extension plate 26. A connecting rope 28 is fixedly connected to one side of the blocking block 23. One side of the connecting rope 28 is fixedly connected to the placement plate 21. The connecting rope 28 is used to connect the blocking block 23 to the placement plate 21, preventing the blocking block 23 from being lost and thus affecting its use. A trapezoidal block 29 is fixedly connected to one side of the blocking block 23. The size of the trapezoidal block 29 on the side away from the blocking block 23 is smaller than that on the other side. By using the trapezoidal block 29 , the size of one side of the stopper block 23 is reduced, making it easier for the stopper block 23 to be inserted into the through hole 22 on one side of the placement plate 21 .

[0031] Reference Figure 1-4As shown, this embodiment discloses a protective assembly 3 provided on one side of the blocking block 23. The protective assembly 3 includes a connecting plate 31 that is engaged with the blocking block 23. A locking hole 32 is defined on one side of the connecting plate 31. The size of the locking hole 32 on the connecting plate 31 matches the size of the blocking block 23. A protective cover 33 is fixedly connected to one side of the connecting plate 31. The size of the protective cover 33 matches the size of the bolt 5. Before the blocking block 23 and the nut 6 block the bolt 5, the connecting plate 31 can be moved so that the protective cover 33 on the side of the connecting plate 31 shields and protects both ends of the bolt 5. When the blocking block 23, the bolt 5, and the nut 6 are engaged in a limited position, the protective cover 33 reaches into the locking hole 32 of the connecting plate 31 to secure the protective cover 33. By using the protective assembly 3, the exposed area of ​​the bolt 5 can be shielded and protected, thereby extending the service life of the bolt 5 and further improving the performance of the fork ring.

[0032] Reference Figure 1-4 As shown, this embodiment discloses a reinforcing plate 34 fixedly connected to one side of the connecting plate 31, and one side of the reinforcing plate 34 is fixedly connected to the protective cover 33. The use of the reinforcing plate 34 improves the connection strength between the protective cover 33 and the connecting plate 31, thereby preventing deformation at the connection between the protective cover 33 and the connecting plate 31. A rubber sleeve 35 is fixedly connected to one side of the protective cover 33, and the size of the rubber sleeve 35 is adapted to the size of the protective cover 33. The use of the rubber sleeve 35 cushions the force when an object collides with the protective cover 33, thereby improving the performance of the protective cover 33.

[0033] Working principle: When using the guide wheel fork ring of the excavator, bolts 5 and nuts 6 are used on the through holes 4 of the shell 1 to fix the fork ring and the pull rod. After the bolts 5 and nuts 6 are fixed to the shell 1, the two blocking plates can be moved so that the blocking plates are inserted into the through holes 22 of the plates 21 on both sides of the shell 1. Then the blocking plates are on the side where the bolts 5 and nuts 6 are away from the shell 1. At this time, the magnet 24 and the iron sheet 25 on the blocking block 23 are adsorbed, and the position of the blocking block 23 is fixed. By using the blocking device 2, the position of the nut 6 and the bolt 5 can be limited to prevent the bolt 5 and the nut 6 from vibrating, which then causes the nut 6 and the bolt 5 to move and finally separate from the two, thereby improving the use effect of the fork ring.

[0034] Before the blocking block 23, the nut 6 and the bolt 5 are blocked, the connecting plate 31 can be moved so that the protective cover 33 on one side of the connecting plate 31 can shield and protect the two ends of the bolt 5. Then, when the blocking block 23, the bolt 5 and the nut 6 are limited and blocked, they will reach the inside of the clamping hole 32 of the connecting plate 31 to fix the protective cover 33. By using the protective component 3, the exposed external area of ​​the bolt 5 can be shielded and protected, thereby improving the service life of the bolt 5 and further improving the use effect of the fork ring.
