Description

TECHNICAL FIELD

[0001] The utility model relates to telescopic beam technical field of stacker, concretely is a kind of stacker telescopic beam's wear-resistant structure. BACKGROUND

[0002] Stacker is widely applied in logistics warehouse and other industries, and the telescopic beam thereof is prone to wear due to various factors during frequent telescopic operation, for example, dust and impurities in the working environment enter the moving parts between the telescopic beams, which can generate friction during telescoping, accelerating the wear of the parts. The telescopic beam is subjected to the weight of goods for a long time and frequent telescoping, which can aggravate the friction between the guide rails and the cooperating parts such as sliding blocks. Moreover, if effective lubrication and protection measures are lacking, the wear problem will be more serious. The wear not only reduces the service life of the telescopic beam, but also can affect the working accuracy and safety of the stacker, increasing equipment maintenance cost and downtime.

[0003] The prior art has the following disadvantages: In the prior art with application number 202321786828.5, a stacker telescopic beam wear-resistant structure is disclosed. The stacker is provided with a load-bearing cross beam and two telescopic beams that are telescoped outward from both ends of the load-bearing cross beam. The wear-resistant structure is arranged at the joint between the load-bearing cross beam and the telescopic beam, and includes a mounting portion arranged at the joint between the telescopic beam and the inner wall of the load-bearing cross beam, an opening through which the telescopic beam passes is provided in the mounting portion; a continuous wear-resistant block attached to the inner wall of the opening on four sides and a positioning block detachably connected to the mounting portion. The positioning block is attached to the outer end surface of the opening and abuts against the continuous wear-resistant block. The continuous wear-resistant block includes a first abutting surface that abuts against the telescopic beam and a second abutting surface that abuts against the inner wall of the opening. The width of the first abutting surface is greater than the width of the telescopic beam. The stacker telescopic beam wear-resistant structure has the advantages of reducing the wear of the metal structure at the joint between the telescopic beam and the load-bearing cross beam, avoiding fatigue cracking of the telescopic beam, and maintaining the strength of the metal structure of the telescopic beam.

[0004] The above-mentioned device uses a wear-resistant structure at the joint between the load-bearing cross beam and the telescopic beam during use. However, since the wear-resistant structure is small, it needs to be replaced after the load-bearing cross beam and the telescopic beam are used for a period of time, which increases the complexity of the operation. Moreover, during telescopic operation of the existing device, dust and impurities can enter the telescopic beam, generating friction during telescoping, which can accelerate the wear of the telescopic beam.
