Description
Technical field
The utility model relates to the crashproof mechanism that dodges of a kind of guardrail cleaning device, particularly a kind of guardrail cleaning device.
Background technology
Existing a kind of guardrail cleaning device, contain and connect support, rocking arm, brush and oscillating oil cylinder; rocking arm places and connects on the support and can rotate around it; the bottom of oscillating oil cylinder is configured to flexible connection with being connected to prop up; its piston rod is hinged on the rocking arm; falsework is loaded on the rocking arm, and brush is installed on the falsework.In order to realize the crashproof function of dodging, be provided with spring between the connection support of above-mentioned guardrail cleaning device and the rocking arm because spring is in its outside, therefore in the working environment that cleans guardrail, meet easily aquatic corrode bad, reduction of service life.When being in retracted state owing to rocking arm simultaneously, extension spring is in maximum extended state always, causes fatigue damage easily, influences application life.
The utility model content
The technical problems to be solved in the utility model provides a kind of crashproof mechanism that dodges of guardrail cleaning device of long service life.
for solving the problems of the technologies described above, the crashproof avoiding mechanism of a kind of guard bar washing device of the utility model, contain connection bracket, rocking arm, oscillating oil cylinder, connecting axle and spring, also contain pedestal, the middle part of this pedestal is bathtub construction, the top of pedestal is provided with elongated slot, the bottom of pedestal is provided with lower elongated slot, upper elongated slot is longer than lower elongated slot, in the bathtub construction at pedestal middle part, contiguous block is housed, the middle part of this contiguous block is provided with groove, the bottom of described oscillating oil cylinder is arranged in this groove, the upper and lower of contiguous block is equipped with the through hole that installing hole that the bottom with described oscillating oil cylinder is provided with matches, described connecting axle is inserted into that pedestal top is provided with elongated slot and bottom is provided with lower elongated slot, in the installing hole that the through hole that the upper and lower of contiguous block is equipped with and the bottom of described oscillating oil cylinder are provided with, one end of described contiguous block and the axis of guide is fixed, the other end of the axis of guide passes the pilot hole that the bathtub construction bottom of pedestal is provided with, the other end of the axis of guide is provided with spacing adjusting nut, described spring is Compress Spring, this Compress Spring is contained on the described axis of guide, and between the bathtub construction bottom of described contiguous block and described pedestal, described pedestal is arranged on connection bracket, the piston rod of described oscillating oil cylinder and rocking arm form hinged.
Dodge in the mechanism the crashproof of above-mentioned guardrail cleaning device, because spring is between the bathtub construction of contiguous block and pedestal bottom, its working environment is improved, so has alleviated the damage of getting rusty, and has prolonged application life; When rocking arm is in retracted state, spring is in the maximum extension state, only is subjected to less pretightning force, has alleviated the fatigue damage of spring, prolonged application life, under the falsework retracted state, be in the fatigue damage that the maximum tension state causes thereby overcome prior art because of spring always.
Description of drawings
Fig. 1 is the crashproof structural representation of dodging mechanism of a kind of guardrail cleaning device of the utility model.
Fig. 2 is the vertical view of Fig. 1.
1. oscillating oil cylinders among the figure are 2. gone up elongated slot, the 3. bottom of oscillating oil cylinder, and 4. connecting axle, 5. contiguous block, 6. groove 7. descends elongated slot, 8. spring, the 9. axis of guide, 10. spacing adjusting nut, 11. pedestals, 12. connect supports, 13. bathtub constructions, 14. rocking arms.
The specific embodiment
Among Fig. 1 and Fig. 2, a kind of crashproof mechanism that dodges of guardrail cleaning device, contain and connect support 12, rocking arm 14, oscillating oil cylinder 1, connecting axle 4 and spring 8, also contain pedestal 11, the middle part of this pedestal 11 is bathtub construction 13, the top of pedestal 11 is provided with elongated slot 2, and the bottom of pedestal 11 is provided with down elongated slot 7, and last elongated slot 2 is longer than down elongated slot 7.In the bathtub construction 13 at pedestal 11 middle parts contiguous block 5 is housed, the middle part of this contiguous block 5 is provided with groove 6.The bottom 3 of described oscillating oil cylinder is arranged in this groove 6, and the upper and lower of contiguous block 5 is equipped with the through hole that installing hole that the bottom with described oscillating oil cylinder is provided with matches.Described connecting axle 4 is inserted into pedestal 11 tops and is provided with in the installing hole that the bottom 3 of through hole that upper and lower that elongated slot 2 and bottom be provided with down elongated slot 7, contiguous block 5 is equipped with and described oscillating oil cylinder is provided with.Described contiguous block 5 is fixed with an end of the axis of guide 9, and the other end of the axis of guide 9 passes the pilot hole that bathtub construction 13 bottoms of pedestal 11 are provided with, and the other end of the axis of guide 9 is provided with spacing adjusting nut 10.Described spring 8 is the compression spring, and this compression spring is contained on the described axis of guide 9, and between bathtub construction 13 bottoms of described contiguous block 5 and described pedestal 11.Described pedestal 11 is arranged on and connects on the support 12, and the piston rod of described oscillating oil cylinder 1 and rocking arm 14 constitute hinged.Dodge in the mechanism the crashproof of above-mentioned guardrail cleaning device, because spring 8 is between bathtub construction 13 bottoms of contiguous block 5 and pedestal 11, its working environment is improved, so has alleviated the damage of getting rusty, and has prolonged application life; When rocking arm 14 is in retracted state, spring 8 is in the maximum extension state, only is subjected to less pretightning force, has alleviated the fatigue damage of spring 8, prolonged application life, therefore overcome prior art is in the fatigue damage that the maximum tension state causes because of spring 8 always under rocking arm 14 retracted states.In actual use, when brush was subjected to external force excessive, rocking arm 14 had the trend of rotating around connection support 12, and at this moment the bottom 3 of oscillating oil cylinder promotes contiguous blocks 5 by connecting axle 4, made the axis of guide 9 outwards mobile, spring 8 pressurizeds, and realization elasticity is dodged.When brush was subjected to normal external force, under the effect of spring 8, rocking arm 14 turned to normal operating position around connecting support 12.
