The upper rocker 1 and the lower rocker 3 are respectively hinged on the frame 4, and the upper rocker 1 and the lower rocker 3 are hinged. Connecting rod 2 is arranged, and one end of connecting rod 2 is hinged with hanging basket part 7; A pulley 5 is installed on the upper rocker 1 to ensure that the hinge axis of the upper rocker 1 and the connecting rod 2 coincides with the rotation axis of the pulley 5; a pull rope 6 is fixed at the hinge point of the lower rocker 3 and the frame 4, and the pull rope 6 The other end bypasses the pulley 5 and is connected to the hanging basket part 7; the stay rope 6 and the double rocker mechanism cooperate with each other to form a posture maintaining mechanism for the hanging basket part 7 to be lifted close to horizontal and lowered close to translation. An oil cylinder 9 is also hinged on the frame 4, and the piston rod 8 of the oil cylinder 9 is hinged with the upper rocker 1; 7 lifting power mechanism.
如图2所示，上摇杆1上端开有U型开口，连杆2穿过上摇杆1U型开口并通过一个销轴A与上摇杆1铰接；在连杆2上开有一个通槽，滑轮5位于连杆2通槽内并转动安装在销轴A上。销轴A上设有用于防止销轴A轴向窜动的限位销轴A 1。As shown in Figure 2, there is a U-shaped opening at the upper end of the upper rocker 1, and the connecting rod 2 passes through the U-shaped opening of the upper rocker 1 and is hinged with the upper rocker 1 through a pin A ; The pulley 5 is located in the connecting rod 2 through groove and is installed on the pin A in rotation. The pin shaft A is provided with a limit pin shaft A 1 for preventing the pin shaft A from moving axially.
如图3所示，下摇杆3为三节结构，下摇杆3包括中间位置的横梁3b和连接在横梁3b上的钢丝绳；在横梁3b与连杆2连接有上钢丝绳3a；在横梁3b与机架4之间连接有相对称的左下钢丝绳3c、右下钢丝绳3d；油缸9的活塞杆8穿过左下钢丝绳3c和右下钢丝绳3d之间。横梁3b上开有排成一排的左边孔K 1、中间孔K 2和右边孔K 3；上钢丝绳3a连接在中间孔K 2上；左下钢丝绳3c连接在左边孔K 1上；右下钢丝绳3d连接在右边孔K 3上。这样的结构为油缸9让出了布置的空间，使双摇杆机构受力为平面力系，以减轻机构的重量。As shown in Figure 3, the lower rocker 3 is a three-section structure, and the lower rocker 3 includes a crossbeam 3b in the middle position and a steel wire rope connected to the crossbeam 3b; Between the frames 4 are connected the symmetrical lower left wire rope 3c and the lower right wire rope 3d; the piston rod 8 of the oil cylinder 9 passes between the lower left wire rope 3c and the lower right wire rope 3d.

工作原理是，双摇杆机构利用摇杆的角度变化与连杆2的角度变化实现车筐高度的变化，当OA=AD时，车筐高度的变化量为杆长OA的1.75倍，当Δy max为吊篮的高度变化量达到10m时，吊篮在水平方向的最小相对位移Δx min/Δy max=-2.9%，吊篮在水平方向的最大相对位移Δx max/Δy max=0.76%，吊篮的水平度最大误差Δθ=10.3º。The working principle is that the double rocker mechanism uses the angle change of the rocker and the angle change of the connecting rod 2 to realize the change of the height of the basket. When OA = AD , the change of the height of the basket is 1.75 times of the rod length OA . When Δ y max When the height change of the hanging basket reaches 10m, the minimum relative displacement of the hanging basket in the horizontal direction Δ x min /Δ y max =-2.9%, and the maximum relative displacement of the hanging basket in the horizontal direction Δ x max /Δ y max =0.76 %, the maximum error of the levelness of the hanging platform Δ θ =10.3º.
其中，双摇杆机构由非线性方程组解出尺寸，曲柄摇块机构由极限位置确定尺寸，其余尺寸由作业高度决定。Among them, the size of the double rocker mechanism is solved by nonlinear equations, the size of the crank rocker mechanism is determined by the limit position, and the other dimensions are determined by the working height.
