Embodiment
In order that those skilled in the art more fully understands the technical solution of the utility model, below in conjunction with the accompanying drawings and have
The utility model is described in further detail for body embodiment.
As shown in Figure 1 to Figure 3, a kind of lowering or hoisting gear for relief grinding casting process, including drive device 1, the driving
Device 1 is specially a kind of dual-axle motor, and two output ends of the drive device are coaxial and symmetrical, are connected to transmission
Mechanism, the transmission mechanism include connecting rod 4, and the connecting rod 4 passes through shaft coupling 2 and the output end of the drive device 1
Connection, the other end of the connecting rod 4 are connected with transfer 3, and the transfer includes an input shaft and two mutual
Coaxial output shaft, symmetrically arranged screw lifting device 6 is connected on two output shafts, specifically, the output shaft
Drive link 5 is connected with, the drive link 5 is connected on the screw lifting device 6, and the top of the screw lifting device 6 is set
There is hoistable platform 10.
The screw lifting device 6 is specially a kind of worm screw lift, specifically includes the worm screw in input driving,
And the leading screw that can be moved up and down under worm drive effect is vertically arranged, the top of the leading screw is fixed with the lifting and put down
Platform 10, it is public noun known to one kind in lowering or hoisting gear to be due to worm screw lift, therefore not specifically illustrated in accompanying drawing
The concrete structure of worm screw lift.
The side of the screw lifting device 6 has been arranged in vertical some proximity switches, and the proximity switch passes through
Control system 11 connects the drive device 1.
Lowering or hoisting gear disclosed in the present application is preferably located in melt pit, and its top is provided with guide rail 8, and the guide rail 8 is used
In carrying rail Shuttling trolley 9, the rail Shuttling trolley 9 is used for transferring pallet 7, because rail Shuttling trolley 9 is present necessarily
Highly, therefore the workpiece on the pallet 7 of its carrying is not easy to relief grinding operation, and lowering or hoisting gear disclosed in the present application can be along Vertical Square
To movement, for lifting the pallet 7 on rail Shuttling trolley 9, as shown in the use state 2 in Fig. 3；When rail Shuttling trolley 9
