Background technology
In the driving operation of screw pump, the drive shaft of motor is attached by the polished rod of coupling arrangement and screw pump
Fixed conveyor moment of torsion, this coupling arrangement, it is made up of shaft coupling 1 and square clamp 2, sees Fig. 6, square clamp 2 is used for blocking polished rod,
Shaft coupling 1 is fixed in the drive shaft of motor, and square clamp 2 is connected by bolt 3 by preceding fixed block and rear fixed block and formed,
The upper end of shaft coupling 1 is provided with square boss 11, and square clamp 2 is provided with the groove being adapted with square boss 11, the square lower end of clamp 2
Groove leans on the gravity pressure of sucker rod in the square boss 11 of the upper end of shaft coupling 1, so as to drive screw pump to be recovered the oil.It is this
Connection device is disadvantageous in that：In screw pump runs at high speed, once being broken, square clamp is just easy to be got rid of to fly out polished rod
Go, produce potential safety hazard.
The content of the invention
The purpose of this utility model is to provide a kind of simple in construction, and connection is reliable, when polished rod fracture, can have
The effect side's of preventing clamp is got rid of winged situation, improve screw pump operational security screw pump polished rod and drive shaft it is anti-rejection
Fly coupling arrangement.
In order to reach object above, technical scheme is used by the utility model：The screw pump polished rod and drive shaft
Anti-rejection winged coupling arrangement, including shaft coupling, square clamp and bolt, square clamp is by preceding fixed block and rear fixed block to being buckled in one
Rise, and be bolted fixed composition, the middle part of square clamp is provided with through hole, and the middle part of shaft coupling is provided with cavity, and its feature exists
In：The upper end of the shaft coupling is fixed with T-shape boss, and the bottom of the bottom of preceding fixed block and rear fixed block is designed with
T-shape neck on same axis, T-shape boss are caught in T-shape neck, the central axis and connection of the through hole of square clamp
The central axis of the cavity of axle device 1 overlaps.
The inwall of the through hole of described square clamp is provided with vertical line and band, and vertical line is located at the top of through hole, and band is located at
The bottom of through hole, the left and right portion of square clamp are respectively equipped with three screws.
The beneficial effects of the utility model are：Simple in construction, connection is reliable, can be effective when polished rod fracture
The side's of preventing clamp is got rid of winged situation, improves screw pump operational security.

Embodiment
Reference picture 1, Fig. 2, Fig. 3, Fig. 4, Fig. 5 make the utility model.The screw pump polished rod and the anti-rejection of drive shaft fly
Coupling arrangement, including shaft coupling 1, square clamp 2 and bolt 3, square clamp 2 is by preceding fixed block 22 and rear fixed block 21 to being buckled in one
To rise, and be connected composition by bolt 3, the middle part of square clamp 2 is provided with through hole 4, so, preceding fixed block 22 and rear fixed block 21
Inwall on be respectively provided with the half of through hole 4, the middle part of shaft coupling 1 is provided with cavity 6, it is characterised in that：The upper end of the shaft coupling 1
T-shape boss 5 is fixed with, the bottom of preceding fixed block 22 and the bottom of rear fixed block 21 are designed with same axis
T-shape neck 9, T-shape boss 5 is caught in T-shape neck 9, the central axis of the through hole 4 of square clamp 2 and the sky of shaft coupling 1
The central axis of chamber 6 overlaps.
The inwall of the through hole 4 of described square clamp 2 is provided with vertical line 7 and band 8, and vertical line 7 is located at the top of through hole 4, horizontal
Line 8 is located at the bottom of through hole 4, and the left and right portion of square clamp 2 is respectively equipped with three screws 10.
During using the utility model, first motor is connected with shaft coupling 1, then polished rod is passed through to the cavity 6 of shaft coupling 1, then
The preceding fixed block 22 of square clamp 2 and rear fixed block 21 are placed on to the both sides of shaft coupling 1, make preceding fixed block 22 and rear fixed block 21
T-shape neck 9 slipped into from both sides on the card of T-shape boss 5, until the opening position of polished rod, with bolt 3 by the preceding He of fixed block 22
Fixed block 21 is connected afterwards, because the inwall of the through hole 4 of square clamp 2 is provided with vertical line 7 and band 8, can prevent polished rod from existing
Arbitrarily slided in through hole 4.If in screw pump runs at high speed, polished rod is broken, the energy of T-shape boss 5 on the top of shaft coupling 1
Enough support fixation side clamps 2, the side's of preventing clamp 2 are moved axially from producing, and square clamp 2 will not be got rid of winged, reduce potential safety hazard.
