Abstract
The invention discloses a vibration damping dolly for step climbing and relates to a dolly. The vibration damping dolly for the step climbing is characterized by consisting of a body (1) and four elastic wheels (2), wherein each elastic wheel (2) consists of pulleys (3), expansion links (4), tension and compression springs (5), fan-shaped check blocks (6), swing bars (7), torsion springs (8) and a wheel disc (9); the wheel disc is connected with three elastic legs through hinges; each elastic leg is formed by connecting one of the swing bars and the corresponding expansion link, and the three elastic legs form a sliding pair; moreover, the tension and compression springs are respectively arranged at joints of the swing bars and the expansion links; while the elastic legs are connected with the wheel disc through the hinges, the three torsion springs are respectively connected with the three swing bars; the wheel disc is provided with the fan-shaped check blocks which are evenly distributed and are adjustable in angle.
Description
Technical field
The present invention relates to a kind of dolly, particularly relate to a kind of stair climbing vibration damping dolly.
Background technology
By stair, transmit goods at present or the disabled's stair activity is all a difficult problem, this device can drive goods or occupant to creep, and can make vibration reduce, guarantee people and goods steadily.
Summary of the invention
The object of the present invention is to provide a kind of stair climbing vibration damping dolly, by four elastic wheels, expansion link, torsion spring and wheel discs, formed, have the advantages that to operate steadily, significantly reduced the vibration producing in motion process, thereby in the process of stair climbing, reach steady vibration damping, fall low noise effect.
The object of the invention is to be achieved through the following technical solutions:
A kind of stair climbing vibration damping dolly, described device is comprised of vehicle body and four elastic wheels, wherein elastic wheel is comprised of pulley, expansion link, drawing-pressing spring, fan-shaped block, swing arm, torsion spring and wheel disc, wheel disc three elastic leg that are connected through the hinge, each elastic leg is formed by connecting by swing arm and expansion link, form moving sets, and drawing-pressing spring is all housed in junction, when elastic leg is connected through the hinge wheel disc, use three torsion springs to connect respectively three swing arms, wheel disc is provided with three fan-shaped blocks that uniform angle is adjustable.
Described a kind of stair climbing vibration damping dolly, described elastic wheel contacts with step surface by elastic leg.
Advantage of the present invention and effect are:
1. three elastic leg that are connected through the hinge of the wheel disc described in, each elastic leg is formed by connecting by swing arm and expansion link, form moving sets, and drawing-pressing spring is all housed in junction, expansion link can be stretched, play buffering absorbing effect, reduce vibration, impact when buffering leg falls contact step surface.Reach the object with ledge surface Elastic Contact, reduce vibration.
2. when the elastic leg described in is connected through the hinge wheel disc, use three torsion springs to connect swing arm and wheel disc, each leads leg this structural limitations and can within the scope of 20 ~ 120 degree, swing, guarantee the hands-off while each other, can guarantee that previous elastic leg not yet exits and the contacting of step, next elastic leg has entered contact, has certain overlap ratio, thereby avoid different leg rotation kiss the earths to produce contact impact, make transmission more steady.Two kinds of elastic element double damping designs can reduce user's uncomfortable impression because jolting and producing in upper process downstairs as far as possible.
Accompanying drawing explanation
Fig. 1 is integral structure schematic diagram of the present invention;
Fig. 2 is elastic wheel structural representation of the present invention.
The specific embodiment
Below in conjunction with accompanying drawing illustrated embodiment, the invention will be further described.
This device is comprised of vehicle body 1 and four elastic wheels 2, and wherein elastic wheel 2 is comprised of pulley 3, expansion link 4, drawing-pressing spring 5, fan-shaped block 6, swing arm 7, torsion spring 8 and wheel disc 9.During work, elastic wheel contacts with step surface by elastic leg, and this device operation is more steady, has significantly reduced the vibration that produces in motion process, thereby in the process of stair climbing, has reached steady vibration damping, the effect that noise is little.
Wheel disc three elastic leg that are connected through the hinge, each elastic leg is formed by connecting by swing arm and expansion link, forms moving sets, and drawing-pressing spring is all housed in junction, expansion link can be stretched, play buffering absorbing effect, reduce vibration, impact when buffering elastic leg falls.Reach the object with ledge surface Elastic Contact, realize the object that reduces vibration.When elastic leg is connected through the hinge wheel disc, use three torsion springs to connect respectively three swing arms, wheel disc is provided with three fan-shaped blocks that uniform angle is adjustable, each leads leg this structural limitations and can within the scope of 20 ~ 120 degree, swing, guarantee the hands-off while each other, can guarantee that previous elastic leg not yet exits and the contacting of step, next elastic leg has entered contact, there is certain overlap ratio, thereby avoid different leg rotation kiss the earths to produce contact impact, make transmission more steady.Expansion link end is equipped with pulley, and cliding friction is transformed into friction of rolling, reduces resistance, moves brisk.
Embodiment 1:
In figure, parts are: this device is comprised of vehicle body 1 and four elastic wheels 2, and wherein elastic wheel 2 is comprised of pulley 3, expansion link 4, drawing-pressing spring 5, fan-shaped block 6, swing arm 7, torsion spring 8 and wheel disc 9.
Propulsive effort pulls vehicle body 1, the wheel disc of elastic wheel 2 rotates, when described elastic leg is connected through the hinge wheel disc, use three torsion springs to connect swing arm, wheeling disk structure limits each swing arm and can within the scope of 20 ~ 120 degree, swing, guarantee the hands-off while each other, can guarantee that previous elastic leg not yet exits and the contacting of step, next elastic leg has entered contact, there is certain overlap ratio, thereby avoid different leg rotation kiss the earths to produce contact impact, transmission is more steady.Wheel disc is rotated further, and device travels forward by pulley, and when pulley runs into step, wheel disc is rotated further next elastic leg and contacts with subsequent another step, and real-time ensuring has two legs in contact, does not impact and collision.Climb successively like this, play buffer action, more steady while making device Pa building.
Claims (2)
1. a stair climbing vibration damping dolly, it is characterized in that, described device is comprised of vehicle body (1) and four elastic wheels (2), wherein elastic wheel (2) is by pulley (3), expansion link (4), drawing-pressing spring (5), fan-shaped block (6), swing arm (7), torsion spring (8) and wheel disc (9) form, wheel disc three elastic leg that are connected through the hinge, each elastic leg is formed by connecting by swing arm and expansion link, form moving sets, and drawing-pressing spring is all housed in junction, when elastic leg is connected through the hinge wheel disc, use three torsion springs to connect respectively three swing arms, wheel disc is provided with three fan-shaped blocks that uniform angle is adjustable.
2. a kind of stair climbing vibration damping dolly according to claim 1, is characterized in that, described elastic wheel contacts with step surface by elastic leg.
