A lifting machine adapting to multiple postures of the human body

Abstract

The invention relates to a shifting machine adaptable to multiple postures of the human body, comprising a mobile frame, a lifting mechanism arranged on the moving frame and having a vertical lifting end surface, a sling for carrying a human body, and a sling connected to the lifting end surface of the lifting mechanism There are several slings, and the sling moves vertically with the lifting mechanism. In the present invention, the human body to be displaced is hoisted by a lifting mechanism with a vertical lifting end surface, and a plurality of parallel lifting points act together on the sling, so that the human body during the displacement will not shake, and the moving center of gravity is always on the moving frame The formed support surface makes the movement of the human body very stable, and does not require the operator to stably lift the human body in addition to the action of pushing the lifting machine; at the same time, the lifting plane is large, which is suitable for the displacement of the human body in various postures, especially It is the posture of the human body that requires a large lifting plane, such as the smooth displacement of the lying posture, so it is suitable for different usage scenarios.

Description

technical field [0001] The invention belongs to the field of machinery, and in particular relates to a shifting machine adapted to multiple postures of a human body. Background technique [0002] Human body lifts currently on the market are mainly composed of a movable single rod, a lifting rod with one end hinged on the upper end of the single rod, and an electric rod connecting the single rod and the lifting rod. The expansion and contraction of the electric rod makes the swing end of the lifting rod The up and down swing of the arc track lifts the human body to be displaced through the up and down shift function of the swing end. [0003] Therefore, the lifting method of the existing human body lift is single-point suspension, which acts on the lifting object at one point. As long as the center of gravity of the lifting object does not coincide with the vertical line of the suspension point, shaking will occur. Therefore, shaking of the lifting object is normal and needs ...

Problems solved by technology

[0003] Therefore, the lifting method of the existing human body lift is single-point suspension, which acts on the lifting object at one point. As long as the center of gravity of the lifting object does not coincide with the vertical line of the suspension point, shaking will occur. Therefore, shaking of the lifting object is normal and needs to be operated. The operator stabilizes the lifting object, thus increasing the difficulty of operation

At the same time, the shaking of the human body during the movement will cause discomfort to the displaced human body.

[0004] In addition, the single-point suspension focuses on one point, so the lifting surface is small, and the hoisted human body is in a curled up state. The human body curled up in the sling may cause secondary injuries during the displacement process, especially for postoperative patients.

However, the human body displacement that requires a large lifting surface, such as lying flat or reclining, cannot be realized with the existing single-point suspension lift, so its use is greatly restricted, for example, it cannot be used for paralyzed patients or ICU patients. It is also impossible to use it in some daily nursing work of bedridden patients.

[0005] In addition, because the lifting process of existing lifts is not simply up and down movement, but also includes horizontal movement, so the lifting of the human body must be accurately positioned, and the operator needs to have certain experience, otherwise it needs to be adjusted to fall into the specified position. location, relatively low work efficiency

[0006] On the other hand, the mobile frame of the existing human body lift is basically a single-rod structure, and its own stability is not good. At present, there are also frame-type designs, but both single-rod and frame structures adopt equal cross-sections. The steel bar profile is welded, and the size of the profile is designed according to the strength required for the position that bears the maximum load. Therefore, the size of the material at the non-maximum load position is beyond the demand. Although it can meet the greater strength requirements, its own weight is heavy. , there are many consumables, and the operation of shifting is not easy and easy, and it also increases the transportation cost

[0007] If in order to reduce weight, instead of using steel rod materials, but using lightweight materials, such as honeycomb composite panels, it will be found that the cost will increase greatly, because when using honeycomb composite materials to make panel components, it must first be based on the structure of the panel components. Making a mold, and then bonding the edge wrapping material to the side of the plate component made of honeycomb composite material, the process is complicated. If you want to make a slight adjustment to the structure of the plate component, you need to make a new mold, so the production cost is high, time-consuming and troublesome
