Cantilever linkage auxiliary device and working method and application thereof

Abstract

The invention relates to a cantilever linkage auxiliary device and a working method and application thereof, and belongs to the technical field of mine and tunnel driving equipment. The auxiliary device comprises auxiliary arms and an auxiliary platform, wherein the auxiliary arms are arranged on both sides of a heading machine main cantilever; the auxiliary arms are connected with a heading machine frame and the heading machine main cantilever; the auxiliary platform is connected with the auxiliary arms. The auxiliary arms are used for supporting the auxiliary platform, and the auxiliary platform is connected with the main cantilever of a conventional heading machine through the auxiliary arms, so that different pieces of auxiliary equipment such as an ultrasonic detector and dust-falling equipment can be conveniently arranged on the auxiliary platform according to different environment demands. The auxiliary platform is always linked with a heading machine body under the limitation of the auxiliary arms on both sides, so that various pieces of equipments can be suspended on the auxiliary platform; linkage movement is mainly driven by the main cantilever without adding any power element, so that the operation is easy, and a control switch does not need to be added; the cantilever linkage auxiliary device is always positioned behind a machine head, and is closer to a working surface, so that a person does not need to get close to the working surface, and the safety of the person is improved.

Description

technical field [0001] The invention relates to a cantilever linkage auxiliary device and its working method and application, and belongs to the technical field of mine and tunnel digging equipment. Background technique [0002] Coal accounts for 70% of my country's total primary energy consumption, much higher than crude oil, hydropower, natural gas and other energy sources, and occupies a dominant position in my country's energy consumption structure. As the main mechanical equipment for digging straight underground roadways in coal mining projects, roadheaders also play an irreplaceable role in the construction of subways, highways and other transportation facilities. They are the main excavating machines for small and medium-sized tunnels and other complex underground rock formations. The roadheader has the advantages of safety, high efficiency and good roadway quality in engineering applications, but the cost is high, the structure is complex, and the loss of the picks ...

AI Technical Summary

Problems solved by technology

One end of this utility model is connected to the telescopic outer cylinder, and the other end is installed on the telescopic protection cylinder, which can be telescopically folded, but the system structure and control system are complex and have single functions, which is not conducive to popularization.

[0007] In summary, the current existing technology still has the following disadvantages: 1. Single function and poor flexibility; 2. The original roadheader has been greatly modified, and the redesign workload for different types of roadheaders is greater, which is not conducive to popularization 3. Due to the limited height of the excavation roadway in the field environment, the height of the above-mentioned roadheaders has increased the body height, which may make it impossible to enter and mine; 4. The protection performance of the equipment is poor, and the gravel avalanche generated during the excavation process will affect the above-mentioned The normal use of the equipment; 5. The mechanism stability of the above equipment is poor, lacking the self-locking function after the movement stops; 6. The damage of the equipment directly affects the normal use of the main function

7. Independent control components are required, the structure is complex, and the control is cumbersome. Therefore, the development of an auxiliary device with wide applicability, safety, stability, and various functions has extremely high promotion value
