An anchor cable drilling rig with Luoyang shovel head for roadway floor

Abstract

The invention provides an anchor cable drilling machine with a Luoyang shovel head for a roadway floor. The anchor cable drilling machine comprises a chassis, a base, a rail baffle, a machine neck, the Luoyang shovel head, a rock swallowing cabin, a rock swallowing cabin fixed rod, a tension spring, a rock fall needle, a motor, a crank and a connecting rod. The base is installed on the chassis. The base, the rail baffle and the machine neck are formed into a whole. The middle of the front of the rail baffle is provided with a groove in the vertical direction. The motor is installed on the machine neck. The Luoyang shovel head is placed in the groove of the rail baffle. A crank sliding block mechanism is composed of the Luoyang shovel head, the connecting rod and the crank. The crank is fixedly connected with an output shaft of the motor. The position, corresponding to the Luoyang shovel head, of the chassis is provided with a through hole. The rock fall needle is fixed to the middle in the groove of the rail baffle. As two walking tracks are arranged underneath the chassis, the anchor cable drilling machine is flexible in movement. In addition, the motor drives the Luoyang shovel head to drill the roadway floor, and drill holes which meet the requirements can be smoothly drilled towards the deep part of the floor. Besides, the rate of hole forming is high, and the depth of formed holes is large.

Description

technical field [0001] The invention relates to a cable-anchor drilling rig, in particular to a cable-anchor drilling rig with a Luoyang shovel head for the roadway floor. Background technique [0002] At present, with the large deformation and instability shown in the high-stress roadway, the excavation and maintenance costs of many projects are doubled, which not only causes safety hazards to the working environment of workers, but also greatly hinders the normal operation of mines. Production. Generally speaking, the deformation of the roadway with high stress and weak surrounding rock is of the whole section nature, not only in the two sides and the vault of the roadway, but also the phenomenon of floor swelling. The deformation of the floor has a great impact on the roadway, which not only reduces the section of the roadway, but also destroys the floor foundation and track of the equipment, which greatly affects the transportation, ventilation and pedestrian requir...

Problems solved by technology

However, the implementation of these measures requires drilling into the floor rock mass, and the quality of the drilling construction directly affects the quality of the anchor rod and anchor cable installation.

In the past, most floor drilling rigs used in mine roadways were rotary twist drill drilling rigs. This kind of drilling rig is widely used, especially when drilling holes in the roof. , but when encountering the floor, there will be deep debris that cannot be removed and the phenomenon of drill sticking, especially when encountering extremely loose rock mass, often occurs when the drill is drilled and then collapses, drill sticks, broken rods, etc., and the drill hole The depth of the roadway should not be too deep, and long anchor cables cannot be installed. As a result, the deformation control of the floor of the roadway with high stress, loose and weak surrounding rocks has not been completely solved for a long time. The key lies in the construction problems of floor drilling and anchor cables.
