specific Embodiment 1

[0050] Such as Figure 1 to Figure 5 As shown, the whole motorized carrier equipment includes an integrally sealed car body 10, on which a wheeled traveling mechanism 8 and a crawler traveling mechanism 7 are installed, and the crawler traveling mechanism 7 can be formed by such as Figure 3 to Figure 5 The lifting mechanism shown is driven to be retracted and supported to play the role of suspension. The specific structures of the wheeled running gear 8 and the crawler belt running gear 7 are the same as those of the corresponding wheeled running gear and crawler belt running gear in the prior art, and will not be repeated here.

[0051] Specifically, a crawler compartment 11 is provided outside the vehicle body 10 for accommodating the retracted crawler running mechanism 7. Correspondingly, the lifting mechanism specifically includes an oil-pneumatic spring 2 and a supporting shaft 4. The supporting shaft 4 passes through the vehicle body 10 in a sealed manner to support the...

specific Embodiment 2

[0065]The main difference between it and Embodiment 1 is that in Embodiment 1, the input crank arm and the oil-pneumatic spring are located inside the vehicle body, and a sealing structure is provided on the supporting shaft to cooperate with the rotation and sealing of the vehicle body. In this embodiment, on the basis of the axial interval distribution of the input lever and the output lever on the supporting shaft, the oil-pneumatic spring and the input lever are exposed outside the vehicle body, although the oil-pneumatic spring will be affected by the external environment at this time. However, because the supporting rotating shaft does not need to be sealed to pass through the car body, there is no need to provide a sealing structure on the car body, so as to avoid the risk of water entering the car body due to accidental seal failure.

specific Embodiment 3

[0067] The main difference between it and Embodiment 1 lies in that in Embodiment 1, a sealing ring is provided on the supporting shaft as a sealing structure to cooperate with the rotation and sealing of the vehicle body. In this embodiment, a sealing ring can be provided on the vehicle body, and the sealing ring is used as a sealing member for rotating and sealing cooperation with the sealing fitting shaft section on the supporting rotating shaft, where the sealing fitting shaft section is used as a sealing fitting structure.

Abstract

The invention relates to motorized carrying equipment and a floating type crawler belt lifting mechanism thereof. The motorized carrying equipment comprises a vehicle body and a crawler belt walking mechanism, the crawler belt walking mechanism is assembled on the vehicle body in a retractable mode through the lifting mechanism, and the lifting mechanism comprises a supporting rotating shaft and a hydro-pneumatic spring; an input crank arm and an output crank arm are arranged on the supporting rotating shaft in the axial direction at intervals, the output crank arm is assembled with the crawler belt walking mechanism in a supporting mode, one end of the hydro-pneumatic spring is hinged to the input crank arm, the other end of the hydro-pneumatic spring is hinged to the vehicle body, and the hydro-pneumatic spring forms an elastic suspension under the gas floating working condition; and the hydro-pneumatic spring can drive the crawler belt walking mechanism to ascend and descend through the input crank arm, the supporting rotating shaft and the output crank arm under the hydraulic drive telescopic working condition. Transmission connection of the hydro-pneumatic spring and the crawler belt walking mechanism is achieved through the supporting rotating shaft and the two crank arms arranged at intervals in the axial direction, the whole transmission structure is effectively simplified on the basis that elastic vibration reduction and folding and unfolding operation are met, the number of needed parts is small, and installation, maintenance and renovation are convenient.

Description

technical field [0001] The invention relates to a motor carrying equipment and a floating crawler lifting mechanism thereof. Background technique [0002] Some special mobile transport equipment is a mechanical device that needs to straddle the boundaries of vehicles and ships. It has the characteristics of a hybrid vehicle when driving on land, and has the characteristics of a ship when sailing on water. It will be the development trend of this type of special vehicles to achieve high speed and high maneuverability both on water and on land. The main configuration of this kind of special equipment at home and abroad is all-wheel type or crawler type, and the crawler belt cannot be lifted or the lifting stroke is small, and the crawler track cannot be completely retracted into the cabin. The track cabin occupies a large space in the vehicle, resulting in small buoyancy. The waterline is deep and the resistance is high, which seriously affects the speed and maneuverability o...
