What are the working components of the drilling rig?

The rock drilling rig is a rock drilling equipment for tunnel and underground engineering using drilling and blasting. It can move and support multiple rock drills for drilling at the same time. So what is he composed of, what is his constituent organization? The following drilling rig manufacturer - Jiangsu Aneng drilling equipment I will explain to you.

凿岩台车的工作组成机构有哪些

The working structure is mainly composed of a propeller, a translation mechanism, a slewing mechanism and a drill arm.


First, the slewing mechanism


The slewing mechanism can be mainly divided into: oscillating rotating column, spiral sub-type rotating column, and polar coordinate drilling arm slewing mechanism.


The structural feature of the oscillating rotating column is that there is a rotatable rotating sleeve 2 outside the rotating shaft 3. The lower end of the drill arm and the lower hinge of the arm cylinder are respectively hinged to the rotating sleeve. When the swing arm cylinder expands and contracts, the rotating sleeve rotates around the axis, thereby driving the drill arm to swing left and right. The oscillating rotary column has a simple structure, reliable operation and convenient maintenance.


Second, the propeller translation mechanism


The translation mechanism commonly used in drilling rigs has two types: mechanical translation mechanism and hydraulic translation mechanism. The mechanical translation mechanism includes: scissor type, plane four-link type and space four-link type; it belongs to the hydraulic translation mechanism with or without translational guide cylinder type and translational guide cylinder type.


Third, the propeller


There are mainly steel rope piston type, wind motor piston type and pneumatic spiral type. The role of the propeller is to enable the rock drilling machine to quickly (or retreat) from the working face when preparing for opening, and to give the rock drill a certain axial thrust during rock drilling. The operation of the propeller should be reversible. The shaft thrust and propulsion speed generated by the propeller should be arbitrarily adjusted to allow the rock drill to operate under optimal axial thrust conditions.


Fourth, the drill arm


The boom is the working arm that supports the rock drill. The structure and size of the boom, the flexibility and reliability of the boom movement will affect the scope of the drill and its production capacity.


According to the action principle of the drill arm: there are three kinds of rectangular coordinates, polar coordinates and composite coordinates.


The Cartesian arm has basic actions such as lifting and horizontal swinging of the boom, pitch and horizontal swing of the carriage (propeller) and compensating motion of the propeller. These actions are realized by the arm cylinder, the swing arm cylinder, the pitch angle cylinder, the bracket swing angle cylinder and the compensation cylinder.


The above is the relevant content of the organization. The drilling rig is mainly composed of rock drill, drill arm (support, positioning and propulsion mechanism of rock drill), steel frame, running mechanism and other necessary auxiliary equipment, and added according to engineering needs. The composition of the equipment.
