Description

Technical Field

[0001] This utility model relates to the field of railway construction equipment, and in particular to a railway construction hoisting and backfilling equipment. Background Technology

[0002] In railway construction, hoisting and backfilling equipment is a type of mechanical equipment used for transporting and backfilling materials. It is used to remove earth, stones, and sand from excavators or other sources. Railway construction involves drilling holes, which are then backfilled. However, the holes are relatively small, making it inconvenient to use mechanical equipment for backfilling.

[0003] Announcement No. CN221739734U discloses a railway construction hoisting and backfilling device, relating to the field of railway construction technology. This utility model includes: a support assembly comprising a base plate and a handle fixed to one side of the upper surface of the base plate; a rotating assembly disposed on the upper surface of the support assembly; the rotating assembly including a bracket fixed to the upper surface of the base plate and a rotating shaft rotatably connected to the upper surface of the bracket; and a moving assembly disposed at the top of the rotating assembly; the moving assembly including a rotating plate fixed to the top of the rotating shaft, a moving plate movably connected to one side of the rotating plate, a through hole on one side of the upper surface of the moving plate, and a hopper passing through the through hole. This utility model, by incorporating the rotating assembly and the moving assembly, solves the problem of inconvenient mechanical backfilling of small drilled holes during railway construction, particularly in small-diameter holes.

[0004] The hopper can be used to backfill small-sized drill holes. However, there is no device to control the flow of the hopper during backfilling. Therefore, a tanker truck needs to be set up to move synchronously with the backfilling equipment to convey and backfill at the same time, which increases the difficulty of the backfilling operation.
