Detailed Description

In order to make the objects, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

Example 1:

a buffer type bucket rope bracket is shown in figure 1 and comprises a bracket bottom 1, a bracket top 2, a buffer device 3 and rollers 4, wherein the bracket bottom 1 and the bracket top 2 are connected through flange bolts 21 to form a frame structure, and the bucket rope bracket in the embodiment is a rectangular frame structure (but is not limited to the shape). The roller 4 is transversely arranged on the bracket bottom 1, and the roller 4 can play a role in rolling contact with the bucket rope, so that the friction force of the bucket rope when the bucket rope rises or falls is reduced, and the service life is prolonged. The buffer device 3 is a strip-shaped elastic piece, two ends of the buffer device 3 are rotatably connected with the bracket bottom 1, as shown in fig. 1, the arrangement direction of the buffer device 3 is consistent with that of the roller 4 and is vertical to the direction of the bucket rope in a use state, the buffer device 3 can absorb the tension of the bucket rope, and when the bucket rope rises or falls in a tightening state, the buffer device 3 can rotate along with the movement of the bucket rope, so that the friction between the bucket rope and the buffer device 3 is reduced. In addition, because the bucket rope bracket is of a closed structure (a closed frame shape is formed by the bracket bottom 1 and the bracket top 2), the bucket rope does not have the risk of jumping out of the frame when swinging.

As an alternative embodiment, the present embodiment may be further configured to: the buffer device 3 is set as a middle ear spring which can be connected with the bracket bottom 1 in a hanging or welding mode.

As an alternative embodiment, the present embodiment and its alternative embodiment can be further configured to: and two ends of the buffer device 3 are connected with the bracket bottom 1 through universal joints 5. Because the buffer device 3 needs to rub against the bucket rope, for example, the middle ear spring as the buffer device 3 has good elasticity, but the middle ear spring tends to twist due to the friction between the middle ear spring and the bucket rope when the bucket rope rises or falls, the middle ear spring can be fixed through the universal joint 5, so that the problem of twisting of the middle ear spring can be solved, the middle ear spring can freely rotate along with the rising or falling of the bucket rope, and the problem of increasing abrasion due to twisting can not occur.

As an alternative embodiment, as shown in fig. 2, the present embodiment and its alternative embodiment can be further selectively configured as follows: the universal joint 5 includes a first rotating portion 51, a second rotating portion 52 and a connecting portion 53, the first rotating portion 51 and the second rotating portion 52 are coaxially and rotatably connected, specifically, the first rotating portion 51 is provided with a slender connecting rod 54 (a dotted line portion in the figure), the second rotating portion 52 is provided with a hole matched with the connecting rod 54, the connecting rod 54 is inserted into the other side of the second rotating portion 52 through the hole, the connecting rod 54 is limited by a nut 55, the connecting rod 54 is prevented from sliding out of the hole, it is noted that the middle portion of the connecting rod 54 and the inner wall of the hole are both unthreaded, and only a part of threads can be arranged at the end portion of the connecting rod 54 for fixing the nut 55. The connecting portion 53 and the second rotating portion 52 are both formed in a fork shape and connected by a cross, and constitute a conventional universal joint 5 structure. More specifically, the first rotating portion 51 may be mounted on the bracket bottom 1 by welding, or may be mounted on the bracket bottom 1 by bolting.

As an alternative embodiment, the present embodiment and its alternative embodiment may be further selectively configured as: the buffer device 3 is externally provided with a sleeve 31. The sleeve 31 may protect the damping device 3.

As an alternative embodiment, the present embodiment and its alternative embodiment may be further selectively configured as: the sleeve 31 is made of polyethylene. The polyethylene material has good impact resistance, and can further prolong the service life of equipment.

The above description is only for the specific embodiments of the present invention, but the protection scope of the present invention is not limited thereto, and any changes or substitutions that can be easily conceived by those skilled in the art within the technical scope of the present invention should be covered by the protection scope of the present invention.
