Device for quickly unloading and storing duct piece of full facer

Abstract

The invention provides a device for quickly unloading and storing a duct piece of a full facer, which comprises an upper seat connecting plate, a lift cylinder upper seat, a lift cylinder, a lift cylinder pin shaft, a girder, a guide wheel pin shaft, a guide wheel, a movable arm, a guide frame connecting plate, a slide block, a balancing slide block, an oil cup, a slide plate chute, a girder groove, a translation cylinder and the like, wherein the upper seat connecting plate is fixedly connected on a heading machine trailer A; the lift cylinder upper seat is in threaded connection and fixation with the upper seat connecting plate; two ends of the lift cylinder are respectively connected with the lift cylinder upper seat and the girder through a chock block and the lift cylinder pin shaft; a guide frame is in threaded connection and fixation with the guide frame connecting plate; the guide wheel pin shaft is installed on the guide frame; and the guide frame connecting plate is fixedly connected on the heading machine trailer A. The device provided by the invention is compact in structure, high in mechanical strength, strong in shock-proof capability, high in construction efficiency and low in comprehensive cost, and is applied to the technical field of full facers.

Description

technical field [0001] The invention relates to a fast unloading and storage device for segments of a full-section roadheader used in the construction of large-scale modern mechanical equipment for excavating subway tunnels, highway railway tunnels and mine tunnels in the technical field of full-section roadheaders. Background technique [0002] At present, the full-face tunnel boring machine is a large-scale modern mechanical equipment for the excavation of subway tunnels, road railway tunnels and mine tunnels. Among them, the construction of the segment is a key step in the construction process of the full-face hard rock roadheader. It should not only meet the requirements of putting the tunnel into use, but also meet the safety and functional requirements during the construction process. For the construction of long-distance and large-diameter tunnels, The number of segments required for each ring is large, and there are higher requirements for the transportation and stor...

AI Technical Summary

Problems solved by technology

In today's full-face tunnel boring machine construction operations, the tunneling efficiency is continuously improved. Once the segment is not delivered in time, it will cause equipment shutdown, seriously affect the tunneling efficiency, and virtually increase the operating cost.

[0003] my country's full-face tunnel boring machine technology is still in the growth stage, the construction diameter is constantly expanding, and the requirements for segment transportation and storage functions are constantly increasing. For this, there are some countermeasures for the actual construction equipment, such as: using a slice feeder to cooperate with The crane provides the segments required for one ring, but the length and capacity of the feeder are limited after all, which has great limitations for large-diameter and high-efficiency construction operations; the tunnel service train is used to directly transport the segments, although the service train More segments can be loaded, but there is no storage capacity, and the continuous supply of segments cannot be guaranteed. The transportation time will become longer and longer as the tunnel continues to excavate, which will affect the excavation efficiency and increase the cost
