Problems solved by technology

[0002] During the construction of tunnels, underground engineering and mining, it is necessary to drill blast holes, but the actual rock drilling section is uneven. In order to ensure the best blasting effect, the rock drilling propulsion beam must be It can always maintain a certain angle with the center line of the tunnel; the leveling of the rock drilling propulsion beam is the key technology. When adjusting the height or left and right position of the main arm, if there is no leveling or callback device under the rock drilling propulsion beam, The rock drilling propelling beam at the top will not be kept parallel to the initial position, which will cause the drilling path to be out of parallel and ultimately affect the blasting effect
[0003] When the drilling arm in the current technical means is in the pitching motion of the main arm, there are many ways of leveling or returning the rock drilling propulsion beam to ensure the translational movement of the rock drilling propulsion beam, but most of the structural layout is relatively complicated, and the translational structure increases When the main arm swings or pitches, it affects its freedom of movement; for example, CN205805428U discloses a drill arm translation mechanism for an excavation drilling rig. The combination of the arm translation signal cylinder and the arm lifting translation cylinder can realize the translation of the rock drilling propulsion beam when pitching, which increases the arm lifting translation signal cylinder on the side of the arm lifting cylinder, thus increasing the overall The layout space of the drilling arm will also affect the freedom of movement of the main arm, which will be restricted when the rock drilling truck turns

Embodiment 1

[0035] Such as figure 1 and figure 2 As shown, it is a rock drilling boom, which includes a boom support platform 1, a main boom swing seat 2, a main boom 5, a telescopic component, a rotating connector 11, a propulsion beam assembly 12, a pitch-translation component and a component capable of driving all The main arm 5 swings horizontally while maintaining the horizontal angle of the propulsion beam assembly 12. The swing arm translation assembly, the main arm 5 is a rectangular tubular structure, and one end of the main arm swing seat 2 is vertically hinged (at The so-called vertical hinge here is to hinge through the vertical twisted shaft, so that under the normal placement state of the rock drilling arm, the hinged position can move horizontally, but cannot move vertically) on the boom support platform 1, the other end is connected to the One end of the main arm 5 is hinged horizontally (the so-called horizontal hinged here is hinged by a horizontal twisted shaft, so th...

Embodiment 2

[0045] The present embodiment is similar to embodiment 1, and its difference is:

[0046] In this embodiment, the propulsion beam pitching and leveling cylinder 10 and the main boom pitching cylinder 6 are respectively located on the upper and lower opposite sides of the main boom 5, and one end of the third oil passage 610 is connected to the rod cavity , the other end is connected to the third cavity 609; in this embodiment, since the telescopic assembly and the main arm 5 are on the same straight line, the line where the main arm 5 is located is the dividing line, and the main arm pitch cylinder 6 is located below the dividing line , the cylinder barrel of the propulsion beam pitch leveling cylinder 10 is connected above the dividing line, when the main boom pitch cylinder 6 stretches out, the propulsion beam pitch leveling cylinder 10 also stretches out to level the angle; the main boom pitch cylinder 6 When retracting, the propulsion beam pitch leveling oil cylinder 10 al...

Abstract

The invention provides a rock drilling drill boom which comprises an arm frame supporting table, a main arm swing seat, a main arm, a telescopic assembly, a rotary connecting part, a boosting beam assembly, a pitching and translation assembly and a swing arm translation assembly capable of driving the main arm to horizontally swing and maintaining the horizontal angle of a boosting beam unchanged.The pitching and translation assembly comprises a main arm pitching oil cylinder and a boosting beam pitching and leveling oil cylinder with the stretching length changing along with the change of the stretching length of the main arm pitching oil cylinder. According to the rock drilling drill boom, only one main arm pitching oil cylinder is adopted by the pitching and translation assembly, the function of lifting the boom is achieved, and the function of signal transmission between the main arm pitching oil cylinder and the boosting beam pitching and leveling oil cylinder is also achieved; and stretching and contracting of the boosting beam pitching and the leveling oil cylinder and stretching and contracting of the main arm pitching oil cylinder are in a direct linear relation, the linkage function is more direct, overall layout space can be reduced, the space utilization rate can be increased, and a drill jambo is more convenient to steer.

Description

technical field [0001] The present invention relates to the field of rock drilling equipment, more specifically, to a rock drilling arm. Background technique [0002] During the construction of tunnels, underground engineering and mining, it is necessary to drill blast holes, but the actual rock drilling section is uneven. In order to ensure the best blasting effect, the rock drilling propulsion beam must be It can always maintain a certain angle with the center line of the tunnel; the leveling of the rock drilling propulsion beam is the key technology. When adjusting the height or left and right positions of the main arm, if there is no leveling or callback device under the rock drilling propulsion beam, The rock drilling propelling beam at the top will not remain parallel to the initial position, which will cause the drilling path to be unable to be parallel, and ultimately affect the blasting effect. [0003] When the drilling arm in the current technical means is in the...
