Description

Technical Field

[0001] The utility model relates to the technical field of excavator buckets, in particular to an excavator bucket packaging fixing bracket. Background Art

[0002] A bucket refers to the bucket installed on an excavator, also called a digging bucket. According to the working method, it is divided into a backhoe bucket and a front shovel bucket. The backhoe bucket is commonly used.

The utility model controls two T-shaped sliding rods to perform centering movement through the positive rotation of the bidirectional screw, and then controls two linkage inclined plates to continuously move, which will eventually cause the lifting platform to rise outside the fixing frame. At this time, the crane can directly put down the excavator bucket outside the fixing frame, and then lock and position the excavator bucket on the lifting platform through two positioning blocks, without the aid of any binding tools, and is easy to operate. Finally, the excavator bucket on the lifting platform is lowered into the fixing frame through the reverse rotation of the bidirectional screw, which effectively avoids the situation where the excavator bucket collides with the fixing frame.

[0004] However, when the excavator bucket loading and fixing bracket in the prior art is in use, the bucket is fixed by a positioning block. During transportation, vibration will occur, and the positioning block reinforced by screws will loosen, causing the bucket to shake and fall, and the bucket cannot be stably fixed. In addition, shaking will occur during transportation, which may cause the clamping structure to be subjected to excessive force and cause damage, causing the bucket to fall, and it cannot effectively absorb the impact force. Therefore, an excavator bucket loading and fixing bracket is needed. Utility Model Content

[0005] The purpose of the utility model is to provide an excavator bucket packaging fixing bracket, which solves the problems in the prior art that vibration will occur during transportation, the positioning block reinforced by screws will loosen, causing the bucket to shake and fall, and the bucket cannot be stably fixed. In addition, shaking will occur during transportation, which may cause the clamping structure to be subjected to excessive force and cause damage, causing the bucket to fall, and the impact force cannot be effectively absorbed.

[0024] Example 1

[0025] like Figure 1-4 As shown, an excavator bucket box fixing bracket shown in the figure includes a base 1 and a clamping mechanism arranged outside the base 1, and the clamping mechanism includes a working component and a clamping component;

[0026] The working assembly includes a rotating disk 2, the rotating disk 2 is arranged outside the base 1, one end of the rotating disk 2 is fixedly connected to a threaded column 3, the outer wall of the threaded column 3 is rotatably connected to a fixed plate 4, and the outer wall of the threaded column 3 is rotatably connected to a limiting ring 5;

[0027] The clamping assembly includes a pushing block 6, the outer wall of the threaded column 3 is spirally connected to the pushing block 6, the inner wall of the top end of the pushing block 6 is fixedly connected to a telescopic shaft 7, and one end of the telescopic shaft 7 is fixedly connected to a clamping ring 8.

[0028] Among them, Figure 3 As shown, the push block 6 is provided with a thread groove that matches the threaded column 3. The threaded column 3 forms a spiral structure with the push block 6 through the rotating disk 2, which is conducive to the rotation of the threaded column 3, causing the spirally connected push block 6 to move, thereby achieving the purpose of clamping and pushing.

[0029] Among them, Figure 3 As shown, the base 1 is provided with a sliding groove that matches the push block 6. The push block 6 forms a sliding structure with the base 1 through the threaded column 3, which is beneficial to prevent the push block 6 from sliding during clamping, ensuring its sliding stability and preventing the clamping part from shifting.

[0030] Among them, Figure 2 As shown, the base 1 is provided with a sliding groove that matches the clamping ring 8. The clamping ring 8 forms a sliding structure with the base 1 through the push block 6 and the telescopic shaft 7, which is beneficial to ensure the stability of the clamping ring 8 on the clamping part and prevent loosening.

[0031] Example 2

[0032] like Figure 1 , Figure 2 and Figure 4 As shown, this embodiment further illustrates Example 1, the bottom of the base 1 is fixedly connected to a bearing plate 9, the bottom of the bearing plate 9 is fixedly connected to a connecting plate 10, the bottom of the connecting plate 10 is fixedly connected to a contraction column 11, the outside of the contraction column 11 is provided with a first spring 12, the bottom of the contraction column 11 is fixedly connected to a base 13, the bottom of the connecting plate 10 is rotatably connected to a connecting rod 14, one end of the connecting rod 14 is rotatably connected to a sliding ring 15, the inner wall of the sliding ring 15 is slidably connected to a connecting rod 16, and the outer wall of the connecting rod 16 is provided with a second spring 17.

[0033] Among them, Figure 4 As shown, the sliding ring 15 is provided with a sliding groove that matches the connecting rod 16. The sliding ring 15 and the connecting rod 16 form a sliding structure through the connecting rod 14, which is beneficial for the sliding ring 15 to squeeze the second spring 17 to achieve a buffering effect.

The positional relationship of the two groups of connecting plates 10, contraction columns 11, first springs 12, bases 13, connecting rods 14 and sliding rings 15 are symmetrically distributed about the central axis of the bearing plate 9, which is beneficial to ensure the balance of the buffering force and prevent tilting caused by different forces on one side.

[0035] When in use: first, the staff rotates the rotating disk 2, so that the rotating disk 2 drives the threaded column 3 to rotate, and under the restriction of the limit ring 5, the spirally connected push block 6 moves on the outer wall of the threaded column 3, and at the same time, the push block 6 slides in the slide groove provided in the base 1, so that the clamping ring 8 positions and fixes the bucket, and the telescopic shaft 7 contracts when in contact, which can prevent loosening, so that the clamping ring 8 stably clamps the bucket;

[0036] Finally, the pressure is borne by the load-bearing plate 9, so that the connecting plate 10 allows the shrinkage column 11 to shrink, and the first spring 12 has a buffering effect. At the same time, the connecting plate 10 causes the connecting rod 14 to change, so that the connecting rod 14 pushes the sliding ring 15 to slide on the outer wall of the connecting rod 16, and the sliding ring 15 squeezes the second spring 17. The second spring 17 provides a reverse force to have a buffering effect. It can effectively play a buffering effect during transportation vibration and prevent the bracket from collision and loss.
