Abstract
The utility model discloses a wheel frame damping device of the small vehicle for climbing stairs, which provides a damping spring between each two adjacent support frames of the cross connected wheel frame for climbing stairs, and makes four small wheels on the wheel frame for climbing stairs under the control of the spring force. When traveling, the utility model alternately transforms in square or oblong shape, having the damping effect, and making the vehicle for climbing stairs travel stably and comfortably. The utility model has reasonable design, simpleness and practicality. J[-130].
Description
The utility model belongs to a kind of shock absorption device that is used to climb the building dolly.
In the past, existing climbing do not have axial folding in the building dolly, and its vehicle frame all is two immutable brachmorphy framves, only be two brachmorphy planes, realizes 180 degree doublings, and shock absorption device is not set on wheel carrier, impacts when therefore driving a vehicle, and it is big to jolt.The Liu Zhi grey hair was understood a kind of " folded climbing pushcar " in 1986, and number of patent application is 8610089.This car can be realized radial and axial folding, particularly this is climbed the right-angled crossing that is provided with on the building dolly axis and connects wheel carrier and controlled by the registration device on the axis, but right-angled crossing launches, make four steamboats place four drift angle places of square, according to rack-and-gear phase occlusal principle, be pressed in successively on each step of stair, climb the building walking.This building dolly of climbing has increased function, and impact and jolt and reduced in when walking, but still steady inadequately.For addressing the above problem, develop a kind of wheel carrier shock absorption device of climbing the building dolly, make climb in the building walking stable, comfortable.
Fig. 1 is a kind of structural representation that has the folded climbing pushcar of wheel carrier shock absorption device.
Fig. 2 is the damping spring front view of wheel carrier shock absorption device.
Fig. 3 is the damping spring birds-eye view of wheel carrier shock absorption device.
Now 1～3 the utility model is described in further detail in conjunction with the accompanying drawings.This building climbing wheel frame shock absorption device, an above damping spring (C) formation that connects wheel carrier (D) all adjacent two bracing frames (B1), (B2) and between two bracing frames (B1), (B2), all is provided with by right-angled crossing.
A kind of type of attachment between the above damping spring (C) is an end of a damping spring, is connected with an end of another damping spring, connects successively.Two ends of the damping spring after the combination are connected with right-angled crossing connection adjacent two supports of wheel carrier (B1), the top (A1) of (B2), (A2) respectively.
To connect adjacent two bracing frames (B1) of wheel carrier (D) at right-angled crossing, the wheel carrier shock absorption device that 2 damping springs (C) formation is set (B2) is an example, its damping spring (C) is by a ring-shaped rubber spring (6), two trough of belt rollers (4), (7), a pressure zone roller (2), three bearing pins (3), (5), (8), connect steel wire (1) more than three, (1A), (9) form, the inboard of ring-shaped rubber spring (6) is arranged on trough of belt roller (4), (7) notch (4A), (7A), pressure zone roller (2) is arranged on the outside near the ring-shaped rubber spring (6) of trough of belt roller (4), by bearing pin (3), (5), connect steel wire (1), (1A), with ring-shaped rubber spring (6), trough of belt roller (4), pressure zone roller (2) is bound up, and connects steel wire (1), the top (A1) of the other end (1A) and bracing frame (B1) connects; Another damping spring (C) is arranged on the outside near the ring-shaped rubber spring (6) of trough of belt roller (7), by bearing pin (8), (8A), connect steel wire (9), (9A), two damping springs (C) are bound up, and the connection steel wire (11) of its other end, (11A) connect with the top (A2) of bracing frame (B2).
The right-angled crossing of climbing the building dolly connects building climbing wheel frame (D), all adjacent two bracing frames (B1), (B2) top (A1), damping spring (C) all is set (A2), four steamboats that make right-angled crossing connect the support of building climbing wheel frame are controlled by the elastic force of spring, can be the square or rectangular checker at heavy burden situation one-sided four steamboats of walking, transform to again in the foursquare process and play cushioning effect transforming to oblong by square, by it in climbing the building walking process, spring load itself is in the stairway step edges and corners, elastic force according to spring itself slows down the steamboat speed of landing that enters the single order step, plays cushioning effect.
Claims (2)
1, climbs the building climbing wheel frame shock absorption device of building dolly, it is characterized in that: between right-angled crossing connection building climbing wheel frame (D) all adjacent two bracing frames (B1), (B2), an above damping spring (C) is set all.
2, according to the described building climbing wheel frame of claim 1 shock absorption device, it is characterized in that: two damping springs (C) are arranged on right-angled crossing connect building climbing wheel frame (D) adjacent two bracing frames (B1), (B2) top (A1), (A2) between, damping spring (C) is by a ring-shaped rubber spring (6), two trough of belt rollers (4), (7), a pressure zone roller (2), three bearing pins (3), (5), (8), connect steel wire (1) more than three, (1A), (9) form, the inboard of ring-shaped rubber spring (6) is arranged on trough of belt roller (4), (7) notch (4A), (7A), pressure zone roller (2) is arranged on the outside near the ring-shaped rubber spring (6) of trough of belt roller (4), by bearing pin (3), (5), connect steel wire (1), (1A), with ring-shaped rubber spring (6), trough of belt roller (4), pressure zone roller (2) is bound up, connect steel wire (1), the top (A1) of the other end (1A) and bracing frame (B1) connects, another damping spring (C) is arranged on the outside near the ring-shaped rubber spring (6) of trough of belt roller (7), by bearing pin (8), (8A), connect steel wire (9), (9A), with two damping springs (C1), (C2) link together the connection steel wire (11) of the other end of damping spring (C2), (11A) top (A2) with bracing frame (B2) connects.
