Balance weight itself is very heavy, and existing moving method usually uses handle and shakes gear-driven mode mobile balanced block, but
It is that this mode needs manual operation, needs to expend larger manpower and go to move.
Summary of the invention
In view of the above-mentioned problems of the prior art, the purpose of the utility model is to provide a kind of shiftings of counter weight of beam unit
Dynamic device, moves balance weight in a manner of more efficient, reduces required manual operation.
A kind of mobile device of counter weight of beam unit that in order to achieve the above purposes, the technical solution adopted by the utility model is:,
Including oil pumping machine crank, gear track, oil pumping machine crank keeps horizontal, and gear track is arranged in surface, and balance weight bottom is fixed
It is provided with the gear engaged, balance weight further includes mounting plate, oil by bolt and the movable dismantling connection of oil pumping machine crank
Cylinder, connecting rod, the mounting plate are connected by being fixed on the strut of its two sides of the bottom with oil pumping machine crank two side ends Vertical movements；
On a mounting board, the oil cylinder is fixedly installed close to the position of balance weight, oil cylinder expansion rod part and the connecting rod are detachable
Connection, and be all to be detachably connected between connecting rod and balance weight, and the threaded hole on oil cylinder telescopic rod, connecting rod and balance weight
Position is conllinear.
Further, sliding rail is provided on oil pumping machine crank two sides, the bottom end of the strut is separately positioned on cunning
In rail, its elastic is adjusted by knob.
Further, a nipple is connected using ball-joint in the end of the oil cylinder expansion rod part, it is described
The both ends of connecting rod are provided with screw thread, likewise, one end on balance weight close to connecting rod is provided with threaded hole.
The utility model has the following beneficial effects: having used mounting plate that oil cylinder is fixedly mounted, the expansion rod part of oil cylinder is same to be connected
Extension bar is detachably connected, and homostasis block is detachably connected connecting rod again, and three position is conllinear, and oil cylinder can be moved with dynamic balance weight
It is dynamic, reduce manual operation, it is more laborsaving, for being frequently necessary to the case where adjusting balance weight position, also accelerate working efficiency.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model；
In figure, 1- oil pumping machine crank, 2- balance weight, 3- bolt, 4- gear track, 5- mounting plate, 6- strut, 7- oil cylinder,
8- connecting rod, 9- nipple, 10- sliding rail, 11- knob.
Specific embodiment
The utility model is described in further detail with reference to the accompanying drawing.
As shown in Figure 1, a kind of mobile device of counter weight of beam unit 2, including oil pumping machine crank 1, gear track 4, oil pumping
Machine crank 1 keeps horizontal, and gear track 4 is arranged in surface, and 2 bottom of balance weight is fixedly installed the gear engaged, balances
Block 2 further includes mounting plate 5, oil cylinder 7, connecting rod 8, the installation by bolt 3 and the movable dismantling connection of oil pumping machine crank 1
Plate 5 is connected by being fixed on the strut 6 of its two sides of the bottom with 1 two side ends Vertical movements of oil pumping machine crank；On mounting plate 5, lean on
The oil cylinder 7 is fixedly installed in the position of nearly balance weight 2, and 7 expansion rod part of oil cylinder and the connecting rod 8 are detachably connected, and even
It is all to be detachably connected between extension bar 8 and balance weight 2, and the screw thread hole site on 7 telescopic rod of oil cylinder, connecting rod 8 and balance weight 2
Collinearly.
In order to facilitate mobile mounting plate 5, sliding rail 10, the bottom end of the strut 6 are provided on 1 two sides of oil pumping machine crank
Be separately positioned in sliding rail 10, by knob 11 to its it is elastic be adjusted, by simultaneously come loose knob 11 can be 5 to mounting plate
It sets and is adjusted, to after suitable position, in tightening knob 11, also, after the adjustment of the position of balance weight 2 is suitable, can will pacify
Loading board 5 is removed.
Nipple 9 one by one, the connecting rod are connected using ball-joint in the end of 7 expansion rod part of oil cylinder
8 both ends are provided with screw thread, likewise, one end on balance weight 2 close to connecting rod 8 is provided with threaded hole.Nipple 9 can
To be flexibly connected with connecting rod 8, and by mutually tightening connecting rod 8 and the threaded hole of balance weight 2, balance weight 2 can be made
Connect with oil cylinder 7, oil cylinder 7 can movement by connecting rod 8 with 2 position of dynamic balance weight by the flexible of telescopic rod.
Utility model device when in use, when needing the position of adjustment block 2, bolt 3 is come loose, connecting rod
8 tighten in the threaded hole of balance weight 2, meanwhile, the position of mounting plate 5 is adjusted, so that the nipple of 7 expansion rod part of oil cylinder
9 can be connected with the other end of connecting rod 8, and 6 position of strut is fastened.Stretching by adjusting the telescopic rod of oil cylinder 7 again,
Take out it when 2 position of balance weight is moved to required position by connecting rod 8 with the position of dynamic balance weight 2, bolt 3 is tight
Gu while 6 knob 11 of strut is come loose, remove mounting plate 5, further work can be carried out.
