Embodiment
To further appreciate that content of the present utility model, the utility model is described in detail in conjunction with the accompanying drawings and embodiments.
Embodiment 1
With reference to Fig. 1, a kind of shearing type lifter realized platform and synchronously declined of the present embodiment, as shown in figure 1, including platform
I11, platform II12, connecting rod rack 2 and base 3, wherein, connecting rod rack 2 is parallel to each other by 2 groups and symmetrical shear type frame group
Into every group of shear type frame is hinged and formed successively by more secondary X-type scissor constructions intersected in end, platform I11 and platform II12
It is installed on by the connecting rod rack 2 on base 3.
As shown in Fig. 2 cylinder component is hinged with each connecting rod rack 2, insurer leads to component 5 and insures claw assembly 7,
Wherein, cylinder component includes oil cylinder and cylinder piston rod, and master cylinder 41, platform are installed on the connecting rod rack 2 below platform I11
Auxiliary oil cylinder 42 is installed on the connecting rod rack 2 below II12, oil cylinder and insurer lead to the lower section that component 5 is articulated with connecting rod rack 2, and
Pin joint is located at the same place of connecting rod rack 2, and cylinder piston rod and insurance claw assembly 7 are articulated with the top of connecting rod rack 2, and cut with scissors
Contact also is located at the same place of connecting rod rack 2.Lift pawl cylinder 6 is installed on insurance claw assembly 7, and below platform II12
Lift pawl cylinder 6 on be provided with magnetic sensor 8.It should be noted that：As shown in fig. 6, in the hydraulic system of shearing type lifter
In, the oil circuit of master cylinder 41 and auxiliary oil cylinder 42 takes series connection, because serial oil cylinders are hydraulic volume synchronous fuel tank, therefore can realize and cut
The synchronous lifting of formula lifting machine, but during the decline of shearing type lifter, scenario described below often occurs in the series connection oil circuit：When
When master cylinder 41 pins, auxiliary oil cylinder 42 is also at locking-in state certainly, i.e. when platform I11 stops declining, platform II12 can also stop
Only decline, so when shearing type lifter can realize synchronous decline, be not in two platforms occur during decline it is single flat
Platform declines, and the situation that another platform does not decline occurs；And when auxiliary oil cylinder 42 pins, master cylinder 41 is but not necessarily also at lock
Firmly state, i.e. platform II12 stop decline when, platform I11 may continue to decline because of failure, so when shearing type lifter can not
Synchronous decline is realized, in order to solve this technical problem, applicant is had found under platform II12 by carefully analyzing above phenomenon
Magnetic sensor 8 is set on the lift pawl cylinder 6 of side, can effectively avoid two platforms from occurring single platform decline during decline,
And the situation that another platform does not decline occurs, and then realize the synchronous decline of two platforms.Reason is as follows：Due under each platform
It is all synchronization action to lift pawl cylinder 6 and oil cylinder, therefore when magnetic sensor 8 receives 6 inner carrier retraction signal of lift pawl cylinder,
Show that now insurer leads to component 5 and insurance claw assembly 7 is changed into engagement from disengaged position, and then also indicate that now secondary oil
Cylinder 42 is in locking-in state, i.e. platform II12 stops declining, and due to being series connection oil circuit between master cylinder 41 and auxiliary oil cylinder 42, therefore
Master cylinder 41 will not pin with the pinning of auxiliary oil cylinder 42, thus now can send induced signal by magnetic sensor 8, and
When pin master cylinder 41, force platform I11 also to stop declining, and then ensure to be not in that platform II12 stops declining, and platform
The situation that I11 continues to decline because of failure occurs.Therefore, by setting magnetic to pass on the lift pawl cylinder 6 below platform II12
Sensor 8, it may be such that the utility model in the case of without manually observing, can find platform I11's and platform II12 in time
Decline situation, make remedying in time, ensure platform I11 and platform II12 synchronous decline process, and then avoid automobile from declining
