Abstract

The utility model discloses a strong two-way wrench which is composed of a five-tooth minor axis, a five-tooth half-axis, a spline half-axis with holes, a sheet gear, a casing, a wrench handle structure and a commutative spanner. The strong two-way wrench adopts a gearset driving type to increase a torque. The utility model has the advantages of high efficiency and convenient operation. The labor intensity can be reduced. The strong two-way wrench is safe and practical. The strong two-way wrench is widely used for twisting and disassembling screw bolts of equipment, such as chemical industry equipment, oil refining equipment, engineering equipment, metallurgy equipment, mining machinery equipment, etc. The strong two-way wrench is especially used for disassembling and assembly the screw bolts whose specifications are big, tensioning force required is strong, and disassembly and assembly are not easy and the screw bolts which are rusted for many years.

Description

Strong two-way wrench
The utility model belongs to nut nut lashing tool.
At present, the bolt and nut lashing tool is general many, but, great majority do not satisfy the bolt and nut that requires lashing force very big, for example, and oil refining, chemical industry, metallurgy, the heat transmission equipment of enterprises such as mine, cooling device, tower equipment, tankage, consersion unit, big machinery etc., its bolt and nut specification are very big, need sizable tight power and just can meet the demands.The now most spanner of band boosting-rods and modes that spanner adds sledgehammer of adopting satisfy tight power requirement, inefficiency torsion inequality so not only, and increased working strength of workers widely.
Provide order of the present utility model a kind of improved have the efficient height, easy to use, alleviate labor strength, can satisfy very big lashing force requires, manual lashing tool.
The utility model by housing, five tooth semiaxis, plate gear, five tooth minor axises, splined hole gear, porose spline semiaxis, interchangeable spanner, hard steel ring, move handle arrangement, screw etc. and constitute.
Moving handle arrangement is made of ratchet, ratchet, bearing pin, pin, spring, handle, trip bolt, shell, change-over switch.
Five tooth semiaxis and porose spline semiaxis are on same axis.One end of five tooth semiaxis inserts in the hole of porose spline semiaxis.
Plate gear is fixed on the five tooth semiaxis.
The splined hole gear is fixed on the porose spline semiaxis.
Plate gear engagement on five tooth semiaxis and the five tooth minor axises, the splined hole gears engaged on five tooth minor axises and the porose spline semiaxis, peace one is moved handle arrangement on the five tooth semiaxis.
Fig. 1,2, the 3rd, structure chart of the present utility model, wherein Fig. 1 has adopted full section and partial sectional view, and Fig. 2 is Fig. 1 part revolved view, and Fig. 3 is the external front face view.
Fig. 4,5 is respectively the vertical view and the front view of replaceable spanner.
Fig. 6 is transmission principle figure of the present utility model.
As shown in Figure 1, 2, 3, housing 1 is fixed as one by screw 16, wear-resisting steel ring 2 is embedded on the housing 1 and (is equivalent to sliding bearing), and five tooth minor axises 3, five tooth semiaxis 4, porose spline semiaxis 5 are installed on respectively on the wear-resisting steel ring 2, installs on the five tooth semiaxis 4 and moves handle arrangement 18.
Five tooth semiaxis 4 and plate gear 7 engagements, plate gear 7 be two of symmetric arrangement, and with five tooth minor axises 3 be one, five tooth minor axises 3 mesh with splined hole gear 6, splined hole gear 6 and porose spline semiaxis 5 are fixed as one.
As shown in Figure 1, the principal character of five tooth semiaxis and porose spline semiaxis is; One end of five tooth semiaxis inserts in the hole of porose spline semiaxis, and can relatively rotate.When moving handle arrangement five tooth semiaxis are rotated, on its axis that coexists, rotate with the equidirectional friction speed.
As shown in Figure 1, 2, moving handle arrangement is made of change-over switch 8, cover plate 9, ratchet 10, ratchet 11, bearing pin 12, pin 13, spring 14, spanner 15, ratchet 10 is fixedly installed on the five tooth semiaxis 4, ratchet 11 is installed on the bearing pin 12, ratchet 11 can be rotated around bearing pin 12, trip bolt 19 is arranged on the handle to stablize boosting-rod.
As shown in Figure 1, 2, the principal character of moving handle arrangement is; When moving handle clockwise, pin 13 is under the effect of spring 14, with the moving ratchet 11 of one thruster, ratchet 11 brake ratchets rotate to clockwise direction, when moving handle counterclockwise, ratchet 11 makes bearing pin 13 compression springs 14 under the effect of the ratchet gear teeth, ratchet 11 loses braking action, and ratchet 10 does not rotate.When needs are counterclockwise braked, can move change-over switch 8, make the another side of pin 13 promote ratchet repetition said process.When ratchet 10 turned over a certain angle, porose spline semiaxis is corresponding to turn over a certain angle, drove replaceable spanner 17 actings.
When wanting fastening a certain nut, suppose to give along clockwise direction motive force P of handle, handle is long to be L, and the moment of torsion that nut is subjected to is M, and five tooth minor axis radius, five tooth semiaxis radius an ancient unit of weight are r, and plate gear and porose spline gear radius are R, then; M=PLR/r * R/r, the moment of torsion that produces is original R/r * R/r times when giving a thrust P, as seen can obtain enough big lashing force under the little situation of exerting oneself.
The replaceable spanner 17 of the utility model can be made series according to the nut standard, so that satisfy the requirement of different size.
What the utility model adopted is the secondary gear type of belt drive, also available multistage or one-level gear-driven form, and also available planet gear-driven form and other gear reduction type of belt drive are made manual wrench, satisfy the needs of high pulling torque.
The utility model be mainly used in engineering construction installation, equipment pick up greatly repair, work such as maintenance, nut dismounting, especially require moment of torsion big, finish the nut very difficult, that labour intensity is big and the nut that is difficult for dismounting that gets rusty for many years more can be brought into play its function with general tool.

Claims (3)
