Abstract
The utility model relates to a moment spanner with a ratchet mechanism for fastening the screw-bolts of railroad sleepers, comprising a control moment mechanism composed of a catch plate shaft, pusher dogs, and a spring, a bi-directional ratchet mechanism, a hand lever, a working sleeve, etc. The catch plate and the pusher dogs in the control moment mechanism are arranged in a body. The pusher dogs are positioned on the both sides of the catch plate; the moment spanner with a ratchet mechanism makes use of the elastic force of a compression spring, by the transference of the oblique plane of the 45 DEG of the pusher dogs and the catch plate, to enable the maximum moment on the catch plate shaft to be equal to a prearranged moment. The ratchet mechanism comprises a ratchet casing, a ratchet, and a pawl. Two working faces which are mutually vertical on the pawl can respectively contact to the two side faces of the ratchet by rotating a regulating handle, which pushes the bi-directional operation of the ratchet. A moment on the catch plate shaft is transferred to the working sleeve by the ratchet mechanism. The moment spanner with a ratchet mechanism controls moment sizes.
Description
The moment spanner of the utility model band ratchet mechanism belongs to hand-operated tools, relates to a kind of energy control moment size and can make the intermittently novel spanner of stepping.
In the prior art, the fastening rail sleeper bolt of railway working system nut all adopt common spanner, with workman's experience with it fastening after, whether measure its Tightening moment with checking tool again meets the requirements, as defective, tighten once more or unclamp, check more then is till moment meets the requirements, labor strength is big, inefficiency.
The purpose of this utility model is development a kind of energy control moment and can makes the intermittently sleeper bolt nut spanner of the band ratchet mechanism of stepping.
The purpose of this utility model can realize by following measure: the moment spanner is by the dial of control moment, pusher dog, the dial axle, spring mechanism, bidirectional ratchet mechanism, handle, compositions such as work sleeve, it is characterized in that: dial is arranged in the main body, cover plate is equipped with on the top, a pusher dog is respectively adorned in the dial both sides, adjustment screw is equipped with in the pusher dog outside, the compression spring is between pusher dog and adjustment screw, handle is contained in the main body two ends, ratchet mechanism is contained between dial axle and the work sleeve, be made up of ratchet and adjusting turn-knob, dial axle upper end is contained in the dial, and the lower end drives ratchet housing and ratchet, the two-way rotation of driving pawl, the work sleeve then links with ratchet shaft.Constitute band ratchet moment spanner.
Aforementioned body can also be designed to the monolever structure, a pusher dog is equipped with in the dial outside, ratchet mechanism between dial lower end and work sleeve is two-way, ratchet and ratchet are housed in the ratchet housing, orthogonal two work arrow faces are arranged on the ratchet, can contact with two working faces that ratchet is vowed respectively, make steel ball compress ratchet by the little spring of adjusting in the screw, a working face on the ratchet is contacted with ratchet arrow face, when the ratchet housing rotates, ratchet pawl promotes the ratchet rotation, the reverse rotation of ratchet housing, ratchet skids on ratchet, and the rotation turn-knob is with the ratchet half-twist, then another plane of ratchet contacts with another arrow face of ratchet, when the ratchet housing rotates, ratchet promotes ratchet and rotates, with did exercises originally opposite, the ratchet housing links to each other with the dial axle, and ratchet shaft and work sleeve join.
Ratchet mechanism can also be installed in below the main body, is contained on the dial axle, and turn-knob makes ratchet mechanism be close to main body being directed downwards, and makes compact conformation between ratchet mechanism and main body.
The utility model compared with prior art has following advantage:
1, simple in structure, easily make, easy to operate, reliable operation.
2, this moment spanner can be set the Tightening moment of bolt and nut in advance, can skid automatically when reaching moment when fastening, and send sound, and not need to remake check, has avoided doing over again.
3, the ratchet mechanism structure is small and exquisite simple, and the human activity scope reduces during operation, and is easy to use, alleviated labor strength, improved work efficiency.
Further describe most preferred embodiment of the present utility model below in conjunction with accompanying drawing.
Accompanying drawing 1 is the structural representation of the utility model most preferred embodiment.
Accompanying drawing 2 is the vertical view of accompanying drawing 1
Accompanying drawing 3 is the another embodiment schematic diagram of ratchet mechanism
Below in conjunction with accompanying drawing, the utility model most preferred embodiment is described in further detail:
Present embodiment is the dual-handle structure, be mainly used in fastening sleeper double-screw bolt, nut, dial (2) pusher dog (3) is arranged in the main body (1), pusher dog (3) contacts with dial (2) inclined-plane, be 45 ° of inclined-planes clockwise, be the sagittal plane counterclockwise, cover plate (6) is fixed on the main body (1) by screw, dial axle (8) connects ratchet housing (9), two pusher dogs (3) are under compression spring (4) effect, depress dial (2) by regulating the variable of compression spring (4), the Tightening moment that makes spanner is in the 80-160 ox scope that requires, and interior six square sockets that are used to rotate the sleeper nut then are bound up with ratchet shaft.
Ratchet (12) is adjusted to clockwise direction, after promoting ratchet (10), turning handle (7) off and on, pusher dog (3) contacts with the last 45 ° of inclined-planes of dial (2), dial axle (8) is gone up and is obtained tangential component and the inclined-plane thereof that its size equates with spring force, all one's effort square that the tangential component of cylinder frictional force is formed, drive the rotation of dial axle (8) and ratchet housing (9), ratchet (12) promotes also up time hour hands rotation of ratchet (10), by interior six square sockets (15) the sleeper nut is progressively tightened, increase along with Tightening moment, pusher dog (3) will retreat under dial (2) stops by the Tightening moment that ratchet mechanism transmitted, spring (4) compress variation of pusher dog (3) back increases gradually, when reaching, Tightening moment gives when setting 80～160 Ns of moments, pusher dog (3) will all withdraw from from the skewed slot of dial, and skid from the arrow top of dial (2), and send " " sound, therefore, sleeper bolt nut fastening force can remain on desired scope automatically by the moment spanner, ratchet (12) is adjusted to counter clockwise direction promote ratchet (10), this moment clockwise direction rotary handle (7), pusher dog (3) contacts with dial (2) sagittal plane, and directly carry-over moment is unclamped bolt and nut.
Claims (5)
1, a kind of moment spanner with ratchet mechanism, dial (2) by control moment, pusher dog (3), dial axle (8), spring mechanism (4,5), bidirectional ratchet mechanism, handle, compositions such as work sleeve, it is characterized in that: dial (2) is located in the main body (1), there is cover plate (6) on the top, a pusher dog (3) is respectively adorned in dial (2) both sides, adjustment screw (5) is equipped with in pusher dog (3) outside, compression spring (4) is positioned between pusher dog (3) and the adjustment screw (5), handle dress main body (1) two ends, ratchet mechanism is contained between dial axle (8) and the work sleeve (15), by ratchet housing (9) ratchet (12), ratchet (10) and knob (11) are formed, and dial axle (8) drives ratchet housing (9) and ratchet (12) and stirs the two-way rotation of the ratchet sleeve (15) of working and then link with dial axle (8).
