Problems solved by technology

However, when the size of the leg mechanism of the power-assisted stretcher is determined, the trajectory of the foot end will no longer change, thus limiting the obstacle-surmounting ability and maneuverability of the whole machine, and the advantages of the leg mechanism cannot be fully utilized, and it cannot adapt to complex working environments.

Embodiment Construction

[0017] Below in conjunction with accompanying drawing, the present invention will be further described

[0018] like figure 1 As shown, a walking carrying platform with adjustable foot track includes a vehicle frame A, first to fourth leg mechanisms B-a, B-b, B-c, B-d.

[0019] The first to fourth leg mechanisms B-a, B-b, B-c, and B-d are all driven by a servo motor and an electric push rod. The electric push rod controls the deformation of the leg mechanism so as to have different foot-end trajectories. The servo motor drives the crank for turnover Movement, so as to realize the traveling function of the carrying platform.

[0020] The frame A is the cargo loading part, and the first to fourth leg mechanisms B-a, B-b, B-c, B-d can adjust the size of the legs according to the change of the actual working terrain, form different foot tracks, and adapt to different terrain changes , so as to realize the function of fast and stable transportation. The vehicle frame A is respec...

Abstract

The invention provides a multifunctional walking carrying platform. The multifunctional walking carrying platform is characterized in that the walking carrying platform with the adjustable foot end trajectory comprises a vehicle frame A, a first leg mechanism B-a, a second leg mechanism B-b, a third leg mechanism B-c, and a fourth leg mechanism B-d; and the vehicle frame A is fixedly connected with a first rack B-a-1 of the first leg mechanism B-a, a second rack B-b-1 of the second leg mechanism B-b, a third rack B-c-1 of the third leg mechanism B-c and a fourth rack B-d-1 of the fourth leg mechanism B-d of a traveling assembly. According to the walking carrying platform with the foot end trajectory adjusting function, when the ground working environment changes, the leg mechanisms can change along with the change of the ground working environment, thus foot ends have the different foot end trajectories, and thus the function of stable advancing under different working environments isachieved.

Description

technical field [0001] The invention relates to a walking carrying platform with adjustable foot-end track, in particular to a kind of driving the size of the leg member through an electric push rod to change, so that the foot end has different walking tracks, and the whole leg mechanism The crank of the servo motor is used to make a full circle rotation to realize the function of traveling, so that the walking carrying platform with adjustable foot track can meet different working needs. Background technique [0002] Chinese patent CN106473868A discloses a kind of "a kind of power-assisted stretcher for individual soldiers". The whole machine has the ability to transport loads on complex ground. However, when the size of the leg mechanism of the power-assisted stretcher is determined, the trajectory of the foot end will no longer change, thus limiting the obstacle-surmounting ability and maneuverability of the whole machine, and the advantages of the leg mechanism cannot b...
