Abstract
The invention discloses a three-hinge point side swing mechanism of a drill carriage connecting rod. A moveable support is hinged with a supporting frame body through a pin shaft; the middle part of the supporting frame body is hinged with a middle hinge point of a three-hinge point connecting rod; a left end hinge point of the three-hinge point connecting rod is hinged with a swing rocking lever; the swing rocking lever is hinged with the moveable support; a hydraulic cylinder is arranged between a right end hinge point of the three-hinge point connecting rod and a permanent hinge base arranged on the supporting frame body; and an included angle alpha formed by connecting lines of the three hinge points on the three-hinge point connecting rod is an obtuse angle. The three-hinge point side swing mechanism has the advantages that: when the three-hinge point side swing mechanism is compared with a traditional side swing mechanism, the effective rotation angle can be increased, and because a proper included angle is adopted among the three hinge points on the three-hinge point connecting rod, the collinear structure performance is better, the bearing stress is more stable, and the rotation angle is bigger. The operation range of a rock drill is wider; the bearing capacity of the rock drill is higher; and because the structure has relatively ideal loading characteristic and rotation characteristic, the side swing mechanism is kept at a uniform speed in a working rotation angle range, and the propelling beam rises and swings stably and accurately.
Description
Technical field
The present invention relates to a kind of rock drilling machinery equipment, is a kind of Three-hinge point side swing mechanism of drill carriage connecting rod specifically.
Background technology
The drill carriage side-swing mechanism is one of component important on the drill carriage, is the key mechanism that drill carriage carries out inclined-plane operation, QL, road surface compensating motion.Domestic existing hydraulic drill rig is owing to the simplicity of pursuing production and design aspect is immature, so that a lot of hydraulic drill rigs all do not adopt the drill carriage side-swing mechanism, can only finish simple road surface punching task, mobility and working environment adaptability are poor, to have the drill carriage of side-sway function then be to adopt the triangle pole side-swing mechanism to later minority on the market, has that structure design is unreasonable, pendulum angle is little, swing speed changes the shortcomings such as violent.Make the swing that forward beam and hammer drill can accurately be unstable.The limitation immature and design of prior art has seriously restricted innovation and the development of oscillating arm mechanisms.
Summary of the invention
The deficiency that exists in order to overcome above-mentioned technology, technical problem to be solved by this invention provide a kind of side-sway scope wide, swing stable, the uniform Three-hinge point side swing mechanism of drill carriage connecting rod of swing speed.
Technical scheme of the present invention is: a kind of Three-hinge point side swing mechanism of drill carriage connecting rod, comprise pallet body, fixed hinged seat, hydraulic cylinder, tri-joint mechanism connecting rod, swing rocking bar, freely movable bearing, it is characterized in that: freely movable bearing is hinged by bearing pin and pallet body, the middle hinge of the middle part of pallet body and tri-joint mechanism connecting rod is hinged, the left end hinge of tri-joint mechanism connecting rod is hinged with the swing rocking bar, it is hinged to swing rocking bar and freely movable bearing, the right-hand member hinge of tri-joint mechanism connecting rod and be installed between the fixed hinged seat on the pallet body and be hinged with hydraulic cylinder.
Three hinge line angle α are the obtuse angle on the described tri-joint mechanism connecting rod.
Advantage of the present invention is: this device can increase effective rotational angle than traditional side-swing mechanism, and adopts suitable angle to make on the tri-joint mechanism connecting rod between tri-joint mechanism to compare to the collinear structure performance better, and stressed more stable, rotational angle is larger.Make the job area of hammer drill wider, supporting capacity is larger, and the while, this structure had more satisfactory mechanical characteristic and gyroscopic characteristics, so that side-swing mechanism maintenance speed in the Work-corner scope is even, forward beam rises, and swing is steady, accurate.
Description of drawings
Fig. 1 is structural representation of the present invention.
The specific embodiment
Now by reference to the accompanying drawings, technology contents of the present invention is described further.
As shown in Figure 1, freely movable bearing 6 is hinged by bearing pin and pallet body 1, the middle hinge of the middle part of pallet body 1 and tri-joint mechanism connecting rod 4 is hinged, the left end hinge of tri-joint mechanism connecting rod 4 is hinged with swing rocking bar 5, it is hinged with freely movable bearing 6 to swing rocking bar 5, the right-hand member hinge of tri-joint mechanism connecting rod 4 and be installed between the fixed hinged seat 2 on the pallet body 1 and be hinged with hydraulic cylinder 3.
Wherein, three hinge line angle α are the obtuse angle on the tri-joint mechanism connecting rod 4.
