Narrow loader multifunctional side-dumping bucket suitable for single track railway tunnel

Abstract

The invention belongs to the technical field of tunnel construction machines, and mainly relates to a narrow loader multifunctional side-dumping bucket suitable for a single track railway tunnel. The narrow loader multifunctional side-dumping bucket suitable for the single track railway tunnel comprises a bucket bottom plate, a bucket top plate, a gate I and a gate II, wherein the gate I and the gate II serve as side wall plates of the bucket; the bucket bottom plate and the bucket top plate form a bucket-shaped structure with the left end, the right end and the front end opened, the gate I and the gate II are arranged at the left end and the right end of the bucket-shaped structure, and a gate rail I and a gate rail II used for the gate I and the gate II to vertically slide respectively are arranged at the left side and the right side of the rear end of the bucket-shaped structure; a rack is fixed to the top of the outer wall face of the bucket top plate, and an arc rail is arranged on the rack; a pin shaft capable of horizontally sliding in the arc rail is correspondingly arranged on the arc rail. The requirement for dreg discharging of the single track railway tunnel and movement of the operation rack is met, multipurpose function and automatic construction are achieved, construction cost is saved, and the construction period requirement is ensured.

Description

Technical field [0001] The invention belongs to the technical field of tunnel construction machinery, and mainly relates to a narrow-body loader multifunctional side-dumping bucket suitable for single-track railway tunnels. Background technique [0002] Tunnel slagging is one of the key links in the tunnel construction operation, and it is the controlling link of the tunnel construction speed; the tunnel slagging is to load the blasted tunnel face muck into the dump truck and transport it to the designated dump site , The equipment required for the slag loading process mainly includes side unloading loaders and slag trucks; type 50 loading has the advantages of high slag loading efficiency and high power, which can take into account the advantages of mobile work benches, and is widely used in tunnel construction. In recent years, railway construction in the western region has been rapid, and the tunnels are concentrated, and most of them are single-track tunnels. The width of the...

AI Technical Summary

Problems solved by technology

In recent years, the railway construction in the western region has been rapid, and the tunnels are concentrated, and most of them are single-track tunnels. The width of the ordinary 50-type loader is relatively large, and the tunnel needs to be expanded and excavated during the slag removal operation. The cost is high and the construction period is long. The ordinary 40-type loader is used. When the type 40 loader performs slag discharge operations, the slag loading efficiency is low and the construction period is long, and the power of the 40 type loader is small, which cannot meet the needs of the mobile work platform; a narrow body loader is designed, and the slag loading efficiency and power are comparable to ordinary loaders. The 50-type loader is the same, and the width is less than or equal to the ordinary 40-type loader, which can meet the construction requirements of single-track railway tunnels. The key to the design of narrow-body loaders is the bucket. Designing a multi-functional bucket that meets the functional requirements is the solution to narrow-body loaders. One of the key technologies
