Specific embodiment
The embodiment of the present invention is described below in detail, examples of the embodiments are shown in the accompanying drawings, wherein from beginning to end
Same or similar label indicates same or similar element or element with the same or similar functions.Below with reference to attached
The embodiment of figure description is exemplary, it is intended to is used to explain the present invention, and is not considered as limiting the invention.
Below by specific embodiment combination attached drawing, invention is further described in detail.
With reference to shown in Fig. 1-4, design a kind of large-scale machine frame tipping arrangement, include driving motor 5, and with the drive
Dynamic 5 connection wire rod nut body 3 of motor, the leading screw and nut mechanism 3 include screw rod and are socketed on the screw rod and institute
The drive seat for stating screw rod adaptation, is hinged with a connecting rod 2 in the drive seat, on the described one end of connecting rod 2 far from the drive seat
It is also hinged with a support rod 7, the support rod is articulated on a support base, and machine frame 6 is fixedly connected with the support rod 7, institute
Stating driving motor 5 drives the screw rod rotation to drive the drive seat to be axially moved, so that the connecting rod 2 is driven to rotate, institute
Stating connecting rod 2 drives the support rod 7 to overturn so that the machine frame 6 is overturn.
At this moment in example, more specifically, deceleration mechanism 4, machine frame are equipped between the driving motor 5 and the screw rod
6 both ends are equipped with the support construction 1 for being used to support the machine frame 6.And the drive seat includes to be socketed on the screw rod
It is articulated on the sliding block with the nut of screw rod adaptation and the sliding block being connect with the nut, the connecting rod 2, machine frame
6 are fixedly connected by four groups of bolt arrangements with the support rod 7.
As a preferred embodiment, in this embodiment, this large size machine frame tipping arrangement is additionally provided with urgency
Stop protecting circuit structure, such as Fig. 4, the emergency stop protection circuit structure includes the fuse and hot relay for protecting circuit
Device.
In the process of running, this large-scale machine frame tipping arrangement provides power by driving motor 5, logical using driving motor 5
Crossing deceleration mechanism 4 drives the screw rod in leading screw and nut mechanism 3 to rotate, and pushes nut and the sliding block being connected with nut along screw rod
It moves axially, and then the connecting rod 2 hinged with sliding block and support frame starts turning, so that connecting rod 2 is transmitted the force to, connecting rod 2
By driving support rod 7 to drive machine frame 6 fixedly connected thereto to overturn.The speed speed that machine frame 6 is overturn can pass through
The revolving speed of driving motor 5 is adjusted to control.People is only needed in this way to adjust driving motor 5 without going and hale machine frame, not only
It ensure that personnel safety while also improving working efficiency.
As shown in Fig. 2, starting driving motor 5, drives screw rod rotation by deceleration mechanism 4 and shaft coupling, push nut into
And sliding block is pushed to be moved forward and backward on being laid with guide rail on the ground, if nut speed is V1, support rod with connecting rod hinge point at
Speed be V2, angular speed ω.So:
Machine frame 6 and support rod 7 are bolted together, overturn from vertical position to horizontal position.Machine frame 6 with
When support rod 7 is in a horizontal position, β=α=90 degree are known by above formula, ω=0, i.e., are fallen finally being turned to horizontal position
At the time of, the angular speed of machine frame 6 is almost 0, will not generate too large impact power to the support construction 1 on ground.
As shown in figure 3, geometrical relationship is as follows:
B-b*sin β=a*cos α
So:
Equalising torque at hinge joint O, so:
FLL=GLc·sinα
FLL=Facos (alpha-beta)
So:
So only it is to be understood that the weight of machine frame 6 and product itself, so that it may reasonable to design support rod 7 and connect
The size of bar 2, to meet intensity and rigidity requirement.
As shown in figure 4, be the emergency stop protection circuit diagram of this large size machine frame tipping arrangement, FU1 is fuse, FR be heat after
Electric appliance all plays a part of to protect circuit, when starting the work of driving motor 5, presses start button SB2, contactor KM1 coil is logical
Electric and self-locking, driving motor 5 starts operation under total pressure.When needing emergency stop, by lower button SB1, contactor KM1 power-off discharges,
Driving motor 5 stops operating immediately.It can effectively prevent the generation of contingency during overturning of machine frame 6
