Assistant measurement unit for moment wrench in narrow operation area
(1) technical field
The present invention relates to torque-measuring apparatus, particularly relate to assistant measurement unit for moment wrench in narrow operation area.
(2) background technology
When adopting securing member to install as topside spare and piping flange in the narrow operation area of boats and ships, because construction space is narrow and small, general moment of torsion wrench can't use.When these securing members were installed in the past, carry out fasteningly by rule of thumb with the urgent method of sledgehammer by the workmen, so the Tightening moment value of these securing members is not quite clear, is difficult to satisfy relevant specification requirement.
(3) summary of the invention
The technical problem to be solved in the present invention, provide a kind of easy to operate, safe and reliable, the accurate assistant measurement unit for moment wrench in narrow operation area of measuring.
The technical scheme that adopts is:
Assistant measurement unit for moment wrench in narrow operation area comprises electric torque spanner, electric torque spanner control display, torque transmission device.Described torque transmission device comprises: upper cover plate, lower cover, the input gear, idler gear, output gear, connect housing, the connecting shaft cover, vertical rod, lock nut, balancing sleeve, the input gear, idler gear and output gear all are contained between upper cover plate and the lower cover, input gear and idler gear engagement, idler gear meshes with output gear again, upper cover plate is connected with the lower cover mount, the transmission spindle nose of the input gear upper end connecting shaft cover of packing into, connecting shaft is sleeved on and connects in the middle of the housing, connect housing and fixedly connected with upper cover plate, the transmission spindle nose of output gear lower end is connected with wrench socket.Upper cover plate and lower cover are provided with arched arm, and arched arm is provided with rectangular slotted eye, and vertical rod is packed in the rectangular slotted eye, lock nut is threaded on the vertical rod, the lower end balancing sleeve that is threaded is equipped with handle on the lock nut, pull the handle locking nut vertical rod is locked on the arched arm.The electric torque spanner is contained on the described connection housing, and use bolted, electric torque spanner output shaft head is packed in the described connecting shaft cover, electric torque spanner control display is connected on the transmission spindle nose of described output gear upper end, constitutes assistant measurement unit for moment wrench in narrow operation area.
Above-mentioned connection housing is connected with upper cover plate, connects housing and is connected with the electric torque spanner, all adopts bolted to connect, and the bolt of its junction all is set with locking resilient sleeve.
Advantage of the present invention is to have solved the problem that narrow operation area internal clamp moment of torsion can't be measured and control, and easy to operate, safe and reliable.

(5) specific embodiment
Assistant measurement unit for moment wrench in narrow operation area comprises electric torque spanner 14, electric torque spanner control display 15, torque transmission device.Described torque transmission device comprises: upper cover plate 1, lower cover 5, input gear 2, idler gear 3, output gear 4, connect housing 6, connecting shaft cover 12, vertical rod 8, lock nut 9, balancing sleeve 10, input gear 2, idler gear 3 and output gear 4 all are contained between upper cover plate 1 and the lower cover 5, input gear 2 and idler gear 3 engagements, idler gear 3 meshes with output gear 4 again, upper cover plate 1 is connected with lower cover 5 mounts, the transmission spindle nose of the input gear 2 upper ends connecting shaft cover 12 of packing into, connecting shaft cover 12 is contained in and connects in the middle of the housing 6, connection housing 6 adds resilient sleeve 11 with upper cover plate 1 with bolt fixedlys connected, and the transmission spindle nose of output gear 4 lower ends is connected with wrench socket 13.Upper cover plate 1 and lower cover 5 are provided with arched arm 16, arched arm 16 is provided with rectangular slotted eye 17, vertical rod 8 is packed into and can be adjusted in the rectangular slotted eye 17, the vertical rod 8 upper ends lock nut 9 that is threaded, the lower end balancing sleeve 10 that is threaded, handle 7 is housed on the lock nut 9, pulls handle 7 lock nuts 9 vertical rod 8 is locked on the arched arm 16.Electric torque spanner 14 adopts the commercial electronic elbow type torque wrench of ETV-DS9-600-25S, be contained on the described connection housing 6, and it is firmly fastening to add resilient sleeve 11 with bolt, electric torque spanner 14 output shaft heads are packed in the described connecting shaft cover 12, connecting shaft cover 12 links together electric torque spanner 14 output shaft heads and input gear 2 transmission spindle noses, when electric torque spanner 14 rotates, driving input gear 2 by connecting shaft cover 12 rotates, electric torque spanner control display 15 adopts commercial TUBSORDS9 type electric torque spanner control display, be connected on the transmission spindle nose of described output gear 4 upper ends, constitute assistant measurement unit for moment wrench in narrow operation area.
Operation principle:
Unclamp lock nut 9, adjust the position of vertical rod 8 rectangular slotted eye 17 on arched arm 16, balancing sleeve 10 is enclosed within by on the securing member that tightly firmware is adjacent, simultaneously wrench socket 13 is enclosed within and is tightened on the securing member, after above-mentioned steps finishes, press the power switch of electric torque spanner, the output shaft head of electric torque spanner 14 rotates, drive input gear 2 by connecting shaft cover 12, idler gear 3, output gear 4 rotates, torsion is sent on the securing member that is tightened by the wrench socket 13 that is connected with output gear 4 lower end transmission spindle noses, when wrench torque reached setting, the reaction force that spanner produced carried out balance by balancing sleeve 10.
