A kind of rock drilling and cracking machine

Abstract

The invention belongs to the field of drilling and splitting devices, and particularly discloses a rock drilling and braking integrated machine. The rock drilling and braking integrated machine comprises a fixed plate, an oil cylinder, a motor, a guide pillar, a pushing ram and a crushing module. The oil cylinder is fixed on the fixed plate, the end head of the oil cylinder is fixedly connected with the motor, a group of sliding blocks are fixedly arranged on the periphery of the motor, and the sliding blocks are connected to the guide pillar in a sleeving mode. The guide pillar is arranged onthe fixed plate, the oil cylinder can push the motor to move up and down along the guide pillar, and a rotating shaft of the motor is fixedly connected with the pushing ram, and the periphery of thepushing ram is connected with the crushing module in a fit mode. The crushing module comprises a wedge block, an installation disk and an expansion link, and the end head of the pushing ram is fixedlyconnected with a drill. When the rock drilling and braking integrated machine is drilled to the design depth, under the action of the pushing ram, the crushing module expands the hole to the surrounding area to achieve rock breaking. The rock drilling and braking integrated machine integrates drilling and splitting to avoid secondary positioning of a crushing rod, so that the drilling and splitting work is carried out in a coherent mode, the working process is simplified, and the working efficiency is improved.

Description

technical field [0001] The invention belongs to the field of rock drilling and splitting devices, in particular to a rock drilling and splitting integrated machine. Background technique [0002] At present, stone mining generally adopts explosive blasting method and splitting method. Due to the high risk of explosive blasting, great safety and stability risks, and problems such as environmental pollution and waste of resources, explosive blasting is not allowed in many occasions. The splitting machine splitting method is low in cost, simple in operation, safe and reliable, but requires prior drilling, which is not efficient, and also has the problem of difficult positioning of the splitting block to the hole. [0003] In the prior art, there are also some equipments that integrate the two functions of rock drilling and splitting, such as the Chinese invention patent "a kind of mountain splitter" of CN202250086U. After the submersible rock drill has drilled the submerged ho...

AI Technical Summary

Problems solved by technology

The existing integrated rock-drilling and splitting machinery has the following defects: the gantry frame and the positioning bracket are rotated and positioned in a large volume, complex structure, and many connection points. Long-term use causes large tolerances and large positioning errors due to equipment wear and tear; Some splitting machines do not have an automatic oiling and lubrication device for the wedge block and the splitting block. They can only manually brush or inject lubricating oil between the wedge block and the splitting block. Frequent shutdowns are required for manual oiling operations, which affects the operation. Efficiency, and increase the labor intensity of the operator
