Description
Technical field
A kind of dismantling belt pulleys frock is the utility model is related to, more particularly to a kind of belt pulley quick-release arrangement.
Background technology
, need to be by changing the motor pulley of different-diameter, to adjust oil pumping in the daily production management process of oil well
Machine jig frequency.Conventional extracting tool, operate laborious time-consuming, and misoperation easily causes rim of pulley fracture damage, no
Welcome by field worker.Simultaneously because the erect-position of operator is higher, there is potential safety hazard.
Utility model content
The purpose of this utility model is to provide a kind of belt wheel for oil pumping machine quick-release arrangement so that dismounting belt pulley is more
It is efficient and convenient.
What the purpose of this utility model was realized in：A kind of belt wheel for oil pumping machine quick-release arrangement, including backboard, institute
State and a pair of pull-rods are installed with backboard, the end of the pull-rod is connected through cross-arm, and screw thread is offered in the middle part of the cross-arm
Hole, jackscrew is provided through in the screwed hole, the end of the jackscrew is connected with the retaining frame for contradicting hydraulic cylinder, the backboard
Middle part offers arc-shaped slot, and the arc-shaped slot, hydraulic cylinder, retaining frame and jackscrew are coaxially disposed.
During utility model works, by the wheel shaft of the arc-shaped slot set upper belt pulley of backboard, the position of hydraulic stem is adjusted,
So that the piston rod of hydraulic cylinder withstands the wheel shaft of belt pulley so that the coaxial setting of wheel shaft, piston rod, now controls hydraulic cylinder to move again
Make so that piston rod promote wheel shaft, now hydraulic cylinder reversely promote cross-arm, pass through cross-arm drive backboard move so that backboard to
Outer pulling belt pulley, disengages it from wheel shaft, is unloaded.Compared with prior art, the beneficial effects of the utility model are, this
Utility model is simple in construction, easy to operate so that dismantling belt pulleys are more convenient.The utility model can be used for machine overhauling of pumping
In.
In order that the installation for obtaining cross-arm is relatively reliable, the end of the pull-rod is machined with concave station, and end is threaded,
The both ends of the cross-arm are sleeved on the concave station, and fixed through nut.
More facilitate in order that obtaining when the utility model uses, the external diameter of the arc-shaped slot is more than the motor shaft diameter of axle, small
In pulley outer diameter.
Brief description of the drawings
Fig. 1 is the utility model structure diagram.
Fig. 2 is the utility model dorsulum structural representation.
Wherein, 1 jackscrew, 2 cross-arms, 3 nuts, 4 retaining frames, 5 pull-rods, 6 hydraulic cylinders, 6a piston rods, 7 wheel shafts, 8 belt pulleys, 9 back ofs the body
Plate, 9a arc-shaped slots.
Embodiment
A kind of belt wheel for oil pumping machine quick-release arrangement as shown in Figure 1-2, including backboard 9, it is installed with backboard 9
A pair of pull-rods 5, the end of pull-rod 5 are connected through cross-arm 2, and the end of pull-rod 5 is machined with concave station, and end is threaded, cross-arm 2
Both ends be sleeved on concave station, and fixed through nut 3, the middle part of cross-arm 2 offers screwed hole, through setting in screwed hole
There is jackscrew 1, the end of jackscrew 1 is connected with the retaining frame 4 for contradicting hydraulic cylinder 6, and the middle part of backboard 9 offers arc-shaped slot 9a, arc
Notch 9a, hydraulic cylinder 6, retaining frame 4 and jackscrew 1 are coaxially disposed, and arc-shaped slot 9a external diameter is more than the motor shaft diameter of axle, less than belt
Take turns 8 external diameters.
During utility model works, by the wheel shaft 7 of the arc-shaped slot 9a set upper belt pulleys 8 of backboard 9, hydraulic stem is adjusted
Position so that the piston rod 6a of hydraulic cylinder 6 withstands the wheel shaft 7 of belt pulley 8 so that wheel shaft 7, the coaxial settings of piston rod 6a, now
Hydraulic cylinder 6 is controlled to act again so that piston rod 6a promotes wheel shaft 7, and now hydraulic cylinder 6 reversely promotes cross-arm 2, passes through the band of cross-arm 2
Dynamic backboard 9 moves so that backboard 9 pulls out belt pulley 8, disengages it from wheel shaft 7, is unloaded.
The utility model is not limited to above-described embodiment, on the basis of technical scheme disclosed in the utility model, this
The technical staff in field is according to disclosed technology contents, it is not necessary to which performing creative labour can is special to some of which technology
Sign makes some and replaces and deform, and these are replaced and deformed in the scope of protection of the utility model.
