Abstract
The invention discloses a parallel connection rod turning mechanism for a resonance crusher. The parallel connection rod turning mechanism comprises a vertical hinge 2, turning cylinders 3, parallel connection rods 4, a support frame 5 and swing arms 6. With the mechanism, sufficient installation spaces are provided for the turning cylinders 3, chambers with the rod and rod-free chambers of the two turning cylinders are connected by adopting a cross parallel connection manner, and a characteristic of the same turning-left speed and the turning-right speed is provided so as to effectively increase equipment operation flexibility, and ensure uniformity of the turning speed; and the dual connection rod mechanism is adopted, such that tension of only the one connection rod is ensured when turning force is transmitted from one side to the other side, and reliability and stability of the mechanism work are effectively improved.
Description
Technical field
The present invention relates to highway engineering machine, the technical field of road building machinery and maintenance of surface machinery relates in particular to a kind of resonance crusher parallel rod steering mechanism that is used for the broken construction operation of rigid pavements such as highway, airport.
Background technology
Overhauling in the transformation process to shabby rigid pavement, if on old surface layer, directly overlay bitumen layer, can be because the native defect of old cement layer causes improved road surface bulk strength not good, under car load is constantly impacted, it is inhomogeneous that old surface layer can bearing capacity occur, cause stress to concentrate and reflex to upper layer, make the new surface layer of overlay the crack occur.In order thoroughly to solve the fatal influence of old pavement to the green road surface layer, the fragmentation of need resonating of old cement pavement, form the mutual embedding of surface layer and squeeze the stable crushable layer of the mutual interlocking of bottom, eliminate native defect, thereby eliminate the reflective crack hidden danger of new shop layer to discharge stress.
The machinery that is used at present the broken construction of cement concrete pavement resonance in the world is mainly resonance crusher, utilizes vehicle-mounted vibrator drive work tup vibration, and tup contacts with the road surface.By regulating the vibration frequency of tup, make its intrinsic frequency near cement panel, excite its resonance, just can easy to do concrete slab be smashed.Regulate the amplitude and the translational speed of tup simultaneously, the granularity and the degree of depth that control is broken are to reach the crushing effect that satisfies requirement of engineering.
Steering mechanism is an ingredient of resonance crusher, and this mechanism is mainly in order to optimize the stability of resonance crusher steering operation, make steering operation flexibly, reliable, about turn to evenly.The steering mechanism that is used for resonance crusher and some engineering machinery in the market mainly adopts the articulated steering mode of two oil cylinder controls, be arranged in the centre of equipment, when such steering mode makes the equipment operation, can not realize the operation of local big steering angle, and the two oil cylinders that adopt radial type to connect provide steering power, when the control of hydraulic control steering wheel turns to, be prone to the inconsistent problem of left and right sides turning velocity.
Summary of the invention
The objective of the invention is at the problems referred to above of the prior art, a kind of resonance crusher steering mechanism is provided, this mechanism adopts the directly mode of control front-wheel steer, the effectively flexibility of raising equipment operation, the reliability that assurance turns to and the uniformity of left and right sides turning velocity.
For achieving the above object, the technical solution adopted in the present invention is:
A kind of resonance crusher parallel rod steering mechanism comprises upright hinge 2, turns to oil cylinder 3, parallel rod 4, bracing frame 5 and swing arm 6.
Wherein, turn to oil cylinder 3 rear ends and bracing frame 5 pin joints, rod end connects with swing arm 6, two parallel linkage 4 connects with two ends swing arm 6, and is flexible by oil cylinder, controls an end swing arm 6 rotations, make other end swing arm 6 rotations by parallel rod 4 again, realize that both sides tire 1 turns to synchronously;
Wherein, swing arm 6 connects with tire 1 axis of rotation, and the installation self-aligning bearing relatively rotates in the middle of tire 1 and the axis of rotation, and swing arm 6 connects by upright hinge 2 with bracing frame 5, and under the oil cylinder effect, swing arm 6 is rotated around founding hinge 2 with tire 1;
Wherein, two turn to the rod chamber of oil cylinder 3 and rodless cavity to adopt the mode of alter-parallel to be connected, and in turning to oil cylinder 3 during fuel feeding, two turn to 3 one of oil cylinders to stretch one to contract by the control of hydraulic control steering wheel, under the acting in conjunction of swing arm 6 and parallel rod 4, realize that tire 1 turns to around upright hinge 2.
Beneficial effect
1, steering mechanism of the present invention is when work, the rod chamber of two oil cylinders and rodless cavity adopt the mode of alter-parallel to be connected, and when changeing certain angle about tire needs, the hydraulic pressure oil mass that needs is fixed, therefore when operation, have the characteristics of left and right sides turning velocity unanimity;
2, steering mechanism of the present invention provides enough installing spaces for turning to oil cylinder, turns to oil cylinder can select enough big stroke as required, thereby realizes big steering angle.
3, steering mechanism of the present invention adopts double connecting rod, two parallel linkage is with swing arm, having formed with upright hinge is parallel four connecting rods of the point of rotation, guarantee that steering force is when a side direction opposite side transmits, all the time connecting rod tension, when avoiding only adopting a connecting rod, this connecting rod is the problem of tension but also pressurized not only, has improved the functional reliability and the stability of mechanism effectively.
Description of drawings
Fig. 1 is the structural representation of steering mechanism of the present invention;
Fig. 2 is the oil circuit connection layout of steering mechanism of the present invention.
Wherein, 1 is tire; 2 are upright hinge; 3 for turning to oil cylinder; 4 is parallel rod; 5 is bracing frame; 6 are swing arm.
The specific embodiment
Below in conjunction with accompanying drawing the present invention is elaborated, thereby protection scope of the present invention is made more explicit defining so that advantages and features of the invention can be easier to be it will be appreciated by those skilled in the art that.
A kind of resonance crusher parallel rod steering mechanism comprises upright hinge 2, turns to oil cylinder 3, parallel rod 4, bracing frame 5 and swing arm 6.
As shown in Figure 1, turn to oil cylinder 3 rear ends and bracing frame 5 pin joints, rod end connects with swing arm 6, two parallel linkage 4 connects with two ends swing arm 6, and is flexible by oil cylinder, controls an end swing arm 6 rotations, make other end swing arm 6 rotations by parallel rod 4 again, realize that both sides tire 1 turns to synchronously; Swing arm 6 connects with tire 1 axis of rotation, and the installation self-aligning bearing relatively rotates in the middle of tire 1 and the axis of rotation, and swing arm 6 connects by upright hinge 2 with bracing frame 5, and under the oil cylinder effect, swing arm 6 is rotated around founding hinge 2 with tire 1.
As shown in Figure 2, two turn to the rod chamber of oil cylinder 3 and rodless cavity to adopt the mode of alter-parallel to be connected, and in turning to oil cylinder 3 during fuel feeding, two turn to 3 one of oil cylinders to stretch one to contract by the control of hydraulic control steering wheel, under the acting in conjunction of swing arm 6 and parallel rod 4, realize that tire 1 turns to around upright hinge 2.
