Ground support device, crawler type escape device and equipment

Abstract

Disclosed are a grounding and bearing device, a crawler-type escape device and equipment. The grounding and bearing device (10) comprises: two frame assemblies arranged in parallel and spaced by a first distance, each of the frame assemblies being formed by sequentially and alternately hinging a plurality of first units and a plurality of second units in series, the hinged axis being horizontal and being perpendicular to the serial direction; a plurality of bearing wheel shafts (1004,1009), two ends of each of the bearing wheel shafts (1004,1009) being correspondingly mounted on the two frame assemblies for connecting the two frame assemblies and providing shaft heads; and first bearing wheels mounted on the shaft heads.

Description

technical field [0001] The invention relates to a ground supporting device, a crawler-type trapping device with the grounding supporting device, and equipment equipped with the crawler-type trapping device. Background technique [0002] Chinese patent document CN106828631A proposes a crawler-type trapping device for existing vehicle trapping devices. The deformation part adopts a parallelogram mechanism, and the distance between the frame and the supporting frame can be changed based on the rotation of the two connecting rods, thus having a tension There are two basic states of opening and retracting. The open state is used for vehicle escape or auxiliary driving under specific road conditions, and the reduction in the stowed state has a greater impact on the passability of the vehicle. [0003] Based on the aforementioned Chinese patent document CN106828631A, the auxiliary support for getting out of trouble depends on the expansion force of the deformation control mechanism...

AI Technical Summary

Problems solved by technology

The controllability of the deformation of the wire harness group is relatively poor, especially in addition to the up and down deformation that can adapt to the terrain, there are also deformations that are parallel to the ground, and deformation forms between these two deformations, resulting in relatively low overall structural stability. poor

[0005] The deformation ability of the wire harness group is also relatively poor, so that the deformation ability of the supporting wheel system is poor during grounding operation, so when encountering more complex terrain, the contact area between the crawler and the ground is small, and the friction required for crawler walking is not enough. full, inefficient walking

[0006] Relatively speaking, even if the road conditions on which the vehicle is running are not good, the driver can effectively avoid larger obstacles if the driver drives the vehicle consciously, so that the vehicle’s operating condition tends to be better. However, in some applications, such as amphibious ships, For amphibious vehicles, etc., when underwater obstacles or climbing from water to land, the adaptability of the supporting wheel system frame constructed by the harness group is relatively poor

[0007] In addition, as the Chinese patent document CN106143030A discloses an amphibious ship, the amphibious ship includes a movable gondola that can be deployed and a deployment mechanism. The movable pod that can be deployed moves between its expanded position and its retracted position. The main body of the movable pod is a crawler chassis structure, and the crawler is driven by a hydraulic system. Drive the crawler chassis to realize the function of land walking, but the movable pod itself for supporting and walking does not have the function of shrinking, and the walking power is provided by the hydraulic system, so it takes up a lot of space and the walking efficiency is low
