A rapid unloading and storage device for full-section roadheader segments

Abstract

A rapid unloading storage device for segments of a full-face roadheader, comprising an upper base connecting plate, an upper base of a lifting cylinder, a lifting cylinder, a pin shaft of the lifting cylinder, a main beam, a pin shaft of a guide wheel, a guide wheel, a movable arm, a connecting plate of a guide frame, a slide block, balance slider, oil cup, slide plate chute, main beam groove, translation oil cylinder, etc., the upper seat connecting plate is fixedly connected on the roadheader trailer A, the upper seat of the lifting oil cylinder is threaded and fixed with the upper seat connecting plate, and the lifting oil cylinder The two ends are respectively connected to the upper seat of the lifting cylinder and the main beam through the stopper and the pin shaft of the lifting cylinder. The guide frame and the connecting plate of the guiding frame are screwed and fixed. On trailer A. The invention has the advantages of compact structure, high mechanical strength, strong anti-vibration ability, high construction efficiency and low comprehensive cost, and is applied in the technical field of full-face boring machines.

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
