Square box shield machine

Abstract

The invention relates to a square box shield machine, which is structurally characterized in that the inner side of a square box formed by combining a plurality of profile steel is provided with a hydraulic distributor; a traveller is fixed between an upper support arm and a lower support arm which are connected with the square box; the traveller is rotatablely connected with a cylinder base and a connecting rod; a hydraulic cylinder which can enable the connecting rod to rise or fall is fixed on the cylinder base; the connecting rod is connected with a hydraulic drilling machine which can rotate vertically; the inner side of the square box is fixedly connected with a hydraulic cylinder which can enable the traveller to swing left and right; the top part of the inner face of the square box is connected with an upper support claw; and the rear part of the bottom face of the square box is connected with a propelling hydraulic cylinder and a lower support claw. The square box is fixed on a rock wall by the support claws, and after a plurality of holes are drilled out at different parts of a driving face by the drill of the drilling machine, rock is split off by using a hydraulic splitter. Dynamite blast is not needed, thereby, the smoke discharge time is saved, the driving speed is accelerated, the peripheral rock of the driving face does not loosen or fall, the safety production is realized, and the production cost is reduced. The square box shield machine has a simple structure and convenience in application and can be widely applied to occasions, such as ore extraction, tunnel driving and the like.

Description

1. Technical field [0001] The invention relates to a mining and tunneling equipment, in particular to a square box shield machine. 2. Background technology [0002] At present, most of the equipment and methods used in mining and tunneling are that the air pump of the rock drill drives the air drill to drill a certain volume of holes on the rocks, and the rocks are crushed and removed by blasting in the holes. Its deficiency of applying above-mentioned equipment and method one is that the dust generated after blasting needs to be discharged to work, and smoke exhaust equipment and a certain period of time are needed during smoke exhaust. The application of equipment increases production costs, and wastes production time during smoke exhaust. If the smoke and dust are not exhausted, it is easy to smoke and damage people; second, the vibration during blasting will loosen and fall off the surrounding rocks of the excavation surface, which may easily cause casualties and product...

Problems solved by technology

Its deficiency of applying above-mentioned equipment and method one is that the dust generated after blasting needs to be discharged to work, and smoke exhaust equipment and a certain period of time are needed during smoke exhaust. The application of equipment increases production costs, and wastes production time during smoke exhaust. If the smoke and dust are not exhausted, it is easy to smoke and damage people; second, the vibration during blasting will loosen and fall off the surrounding rocks of the excavation surface, which may easily cause casualties and production safety accidents; third, it is easy to mix ore and non-ore during blasting, making the The recovery rate is low; the fourth is that the rock drill cannot realize multi-dimensional space drilling, and the required holes cannot be drilled in various parts of the excavation surface; the fifth is that the cost of materials such as explosives and detonators is high, and the flow of explosives into the society will also bring social security. factor
