The invention relates to a lifting platform and a high-altitude rescue vehicle, and the lifting platform comprises at least one section of lifting unit, and each section of lifting unit comprises a shear fork piece which comprises a first fork arm and a second fork arm which are arranged in a crossed manner and are hinged with each other through a hinge shaft; the first supporting piece comprises a first part and a second part which are hinged through a first hinging piece, and the first part and the second part are connected with one end of the first fork arm and one end of the second fork arm respectively; the second supporting piece comprises a third part and a fourth part which are hinged through a second hinging piece, and the third part and the fourth part are connected with the other end of the first fork arm and the other end of the second fork arm respectively; the driving piece drives the first hinge piece and the second hinge piece to get close to or away from the hinge shaft. According to the lifting unit, when the first hinge shaft and the second hinge shaft are close to the hinge shafts, the height of the lifting unit in the vertical direction is decreased. And when the first hinge shaft and the second hinge shaft are far away from the hinge shafts, the height of the lifting unit in the vertical direction is increased, so that high-altitude operation can be conveniently carried out on the top of the lifting unit.
本发明涉及一种升降平台和高空救援车,包括至少一节升降单元,每节升降单元包括:剪叉件,包括交叉设置且通过铰接轴相互铰接的第一叉臂和第二叉臂;第一支撑件,包括通过第一铰接件铰接的第一部分和第二部分,第一部分与第二部分分别与第一叉臂和第二叉臂的一端连接;第二支撑件,包括绕通过第二铰接件铰接的第三部分和第四部分,第三部分与第四部分分别与第一叉臂和第二叉臂的另一端连接;驱动件带动第一铰接件和第二铰接件靠近或远离铰接轴。上述升降单元,第一铰接轴和第二铰接轴靠近铰接轴时,升降单元在竖直方向的高度变小。第一铰接轴和第二铰接轴远离铰接轴时,升降单元在竖直方向的高度变大,以便于在升降单元的顶部进行高空作业。
