Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the utility model is described in detail.The present embodiment is implemented premised on technical solutions of the utility model, give detailed embodiment and concrete operating process, but protection domain of the present utility model is not limited to following embodiment.
Based on a lifting stabilizing device for scissors fork assembly, as shown in Figure 1, comprising:
Crane, comprises the upper frame 3 and underframe 4 that be arranged in parallel, and connects upper frame 3 and underframe 4 and for controlling the lifting mechanism that upper frame 3 is elevated;
Also comprise:
Scissors fork assembly 1, its both sides are connected with upper frame 3 and underframe 4 respectively, for making upper frame 3 and underframe 4 keeping parallelism in upper frame 3 lifting process.
Upper frame 3 and underframe 4 are provided with two rotating shafts be arranged in parallel 6 respectively, assembly 1 is pitched in four rotating shafts 6 respectively four legs 11 with scissors are fixedly connected with, concrete, scissors fork assembly 1 and rotating shaft 6 are bolted, and are arranged on the bearing seat 5 on upper frame and underframe.
As depicted in figs. 1 and 2, rotating shaft 6 two ends are provided with helical wheel 2, and this helical wheel 2 with engage each other with the helical wheel 2 in another rotating shaft 6 of body side frame, to realize the synchronous axial system of two rotating shafts.
Lifting stabilizing device also comprises multiple expansion sleeve 7 for adjusting helical wheel 2 installation site, and helical wheel 2 is located in rotating shaft 6 by expansion sleeve 7; By adjusting the installation site of helical wheel 2, realize the compensation of the Mismachining tolerance to helical wheel 2 width between centers.
Lifting mechanism comprises drive motor 31, transmission shaft 32, two belt pulleys 33 and at least two belts 331, two belt pulleys 33 are all located on transmission shaft 32, and be connected with drive motor 31 by transmission shaft 32, the reverse winding in two ends of belt 331 is on belt pulley 33, and be connected with underframe 4, concrete, as shown in Figure 1, belt 331 is through the reverse winding in two ends after underframe 4 on belt pulley 33, and the winding of two belt 331 difference is on two belt pulleys 33.
