The comprehensive mechanization stone drift heading machine set is characterized by also comprising a rotation part, two side supporting devices and top and bottom plate supporting devices. The comprehensive mechanization stone drift heading machine set disclosed by the invention is improved and perfected to enable the structure design to be more reasonable and compact, and the performances, such as working efficiency, stability, reliability, and safety of the set, are improved. Comprehensive mechanization construction equipment is provided for mine underground stone drift heading, and is especially adaptive to the underground stone drift mechanization operation and construction of various big, medium and small mines.

Description

technical field [0001] The invention belongs to the technical field of coal mine underground development equipment, in particular to a comprehensive mechanized rock roadway excavation unit suitable for the mechanized development of underground rock roadways in large, medium and small coal mines. Background technique [0002] In the field of coal mine development equipment technology, the traditional method of tunneling in various mines is mainly blasting, and the support methods are combined support of bolts, anchor cables, joists, and anchor nets. The gun excavation is drilled, charged, and blasted with an air-leg pneumatic drill; the gangue falling from the blasting is first manually crushed and then transported out of the working face by a rock rake machine; support. There are mainly following problems in this blasting rock roadway excavation construction method: [0003] 1. The excavation section of the roadway is small: the excavation section is generally about 15 squ...

AI Technical Summary

Problems solved by technology

[0003] 1. The excavation section of the roadway is small: the excavation section is generally about 15 square meters. When the height of the roadway exceeds 2m, scaffolding must be set up to carry out the construction of the roof anchor rod and anchor cable;

[0004] 2. Non-mechanized operations: Blast hole construction and gangue crushing are all manual operations. The single pneumatic drill is still used for the construction of the top bolt and anchor cable of the supporting roadway, while the hand-held pneumatic drill is used for the construction of the side anchor rod and anchor cable. The thrust of drilling comes from people. arms and arms, the labor intensity of the workers is high

Since the construction of the anchor bolts and cables mainly depends on manpower, the construction quality of the anchor bolts and cables cannot be guaranteed fundamentally;

[0005] 3. Slow construction speed: when the height of the construction section exceeds 2m, scaffolding must be built and dismantled, which takes a lot of time; when the width of gangue exceeds 300mm, it must be broken manually, which takes a lot of time, otherwise the main transportation system will be damaged

The overall construction cycle progress is low, all within 2m;

[0006] 4. Low efficiency: Since drilling, crushing gangue, and bolt and anchor cable support are all manual operations, there are many construction workers, resulting in low operation efficiency;

[0007] 5. Low safety factor: construction workers work alternately at high altitude, and the working safety environment is poor

Drilling, crushing gangue, and bolt and cable support are all carried out under the empty roof, posing potential safety hazards;

[0008] 6. Poor working environment: the gun smoke after blasting and the dust during spraying are likely to cause lung diseases of construction workers and affect the health of workers

[0012] 2. The support height of the advanced support device of the integrated mechanized rock roadway tunneling unit is relatively low, and most of them are not perfectly combined with the roadheader. After folding, the volume is relatively large, and the adaptability to the roof is poor, especially when the roof slope is serious. poor sex

[0013] 3. The roof bolt and anchor cable drilling rig of the comprehensive mechanized rock roadway excavation unit is always exposed to the frame during the construction process of walking, excavation cutting and temporary support, which affects the operation of these processes and is easy to be damaged by falling rocks. The structural design and installation position of the bolt and cable drilling rig are unreasonable

[0014] 4. When the comprehensive mechanized rock roadway tunneling unit is working, for the whole machine, it only depends on the support and stability of this base plate support component, its function is not ideal, and the stabilizing effect is poor
