Description

Technical Field

[0001] The utility model relates to a lifting beam, in particular to a novel lifting beam, and belongs to the technical field of lifting equipment. Background Art

[0002] The bucket is a commonly used transportation tool during the construction of vertical shaft drilling. The lifting beam, also known as the bucket beam, is a component of the bucket. The barrel body of the existing bucket is connected by ear plates, pins and bucket beams. Since the materials used for the bucket beam, ear plates and pins are similar, it is found during the use of this structure that the bucket beam, ear plates and pins are severely worn in a short time and need to be replaced frequently, so the maintenance cost is very high. At the same time, the ear plates and the barrel body are riveted, and on-site replacement is also very troublesome, which often affects production. In view of the above problems, the utility model proposes a new solution. Utility Model Content

[0003] The main purpose of the utility model is to solve the deficiencies of the prior art and provide a novel lifting beam.

[0004] The purpose of the utility model can be achieved by adopting the following technical solutions:

[0005] A novel lifting beam comprises a V-shaped barrel beam and a bucket, wherein the barrel beam and the bucket are connected via an ear plate and a pin, the ear plate is connected to the bucket via rivets, a connecting hole cooperating with the pin is provided on the barrel beam, a cushion sleeve is installed inside the connecting hole.

[0006] Furthermore, the gasket sleeve is a cylindrical gasket sleeve, and the gasket sleeve is a copper gasket sleeve.

[0007] Furthermore, there is an interference fit between the cushion sleeve and the connecting hole.

[0008] The beneficial technical effect of the utility model is as follows: according to the new lifting beam of the utility model, through the provision of the gasket and the connecting hole, the gasket can be padded at the connection between the barrel beam and the pin shaft during use, so that the barrel beam, the ear plate and the pin shaft are protected by wearing the gasket during use. After using for a period of time, only the gasket needs to be replaced, and the replacement of the gasket is convenient and quick, and the maintenance cost is low. BRIEF DESCRIPTION OF THE DRAWINGS

[0012] In order to make the technical solution of the present invention more clear and specific to those skilled in the art, the present invention is further described in detail below in conjunction with embodiments and drawings, but the implementation methods of the present invention are not limited thereto.

[0013] like Figure 1 and Figure 2 As shown, the novel lifting beam provided in this embodiment includes a V-shaped barrel beam 1 and a barrel 2, the barrel beam 1 and the barrel 2 are connected by an ear plate 3 and a pin 4, the ear plate 3 is connected to the barrel 2 by a rivet, and a connection hole 5 that cooperates with the pin 4 is provided on the barrel beam 1, and a cushion sleeve 6 is installed inside the connection hole 5. Through the arrangement of the cushion sleeve 6 and the connection hole 5, the cushion sleeve 6 can be cushioned at the connection between the barrel beam 1 and the pin 4 during use, so that the barrel beam 1 and the pin 4 are protected by wearing the cushion sleeve 6 during use, and the cushion sleeve 6 only needs to be replaced after a period of use, and the cushion sleeve 6 is easy and quick to replace, and the maintenance cost is low.

[0014] The gasket sleeve 6 is a cylindrical gasket sleeve 6 made of copper. The gasket sleeve 6 and the connecting hole 5 are in interference fit. The barrel beam 1, the pin shaft 4 and the ear plate 3 are all made of alloy steel with a hardness greater than that of copper.

[0015] The above is only a further embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the scope disclosed by the present invention according to the technical solution and concept of the present invention, which fall within the protection scope of the present invention.
