Abstract
The utility model relates to a multi functional hand operating spanner, which comprises a handle, a clutch and a working sleeve. The upper end of the connecting rod is moveably connected with the handle, and the lower end is fixed with the spline shaft through the locking nut, and the spline shaft and the clutch are in a spline connecting, and a spring is pressed on the clutch. A linking bracket is connected with another clutch, and is connected with the ratchet assembly coat. The connecting rod of the spanner can be in a removable assembling according to the using requirement. The installing of the ratchet assembly and the linking bracket can realize the loosing and tightness of the bolt nut through the rotating of the ratchet. The utility model can randomly adjust the fixing torsional moment of the nut to ensure the nut torsional moment meeting the requirement of working. A rotary shield is additionally installed, and the connecting rod is very convenient to be rotated by using hand with high working efficiency. The spanner is light with a compact structure, which is convenient for carrying.
Description
Technical field
The utility model relates to a kind of railway special spanner, particularly the iron sleeper bolt and nut of standing motionless is carried out pine and unloads the railway special-purpose multifunctional manual wrench of using with the m of w working platform of fastening usefulness.
Background technology
At present, the hand spanner of rail track worker use has the following disadvantages: extension bar is the fixed bar that is welded as a whole, and is heavy and non-dismountable.Can only adapt to a kind of posture and use, labour intensity is big.Existing in addition manual wrench can not be adjusted moment of torsion, and moment of torsion can not be located, and can only loosely or stubborn consolidate a kind of nut, and it is not too convenient to manipulate.
Summary of the invention
The purpose of this utility model aims to provide that a kind of extension bar is detachable, moment of torsion can be regulated, vertical crouching formula all can be used, high efficiency, and labour intensity is low, can pine twists the railway special-purpose multifunctional manual wrench of any bolt and nut, in order to overcome disadvantages of background technology.
The technical scheme that realizes the foregoing invention purpose is: a kind of railway special-purpose multifunctional manual wrench, comprise handle, clutch and work sleeve, its structural feature is that the upper end of extension bar and handle flexibly connect, its lower end and splined shaft are fastening by lock nut, splined shaft is connected with clutch 15 splines, and spring is crimped on the clutch 15, and hitch is connected with clutch 14, hitch is connected with ratchet assembly overcoat 11, and the work sleeve is connected with cover 13 in the ratchet assembly.
Owing to adopted said structure, extension bar of the present utility model can be according to the quick disassembly and assembly of instructions for use.The setting of ratchet assembly and hitch can realize by the upset of ratchet the pine of bolt and nut with tight.Can adjust the tightening torque of nut arbitrarily, guarantee that nut torque meets worker's requirement of being engaged in.Since installed the rotation sheath additional, very convenient with hand rotation extension bar, high efficiency.This spanner portable structure compactness is easy to carry.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
The specific embodiment
Below in conjunction with drawings and Examples in detail the utility model is described in detail.
As accompanying drawing 1, the utility model is by handle 1, extension bar 3, pinning nut 4,5, clutch 14,15, compositions such as hitch 16, splined shaft 17.Handle 1 with holes round handle in the middle of being, its two ends are with taper knob.The upper end of extension bar 3 is inserted in the hole of handle 1 centre, fixes with nut.Rotation sheath 2 is being overlapped on the top of extension bar 3, and rotating sheath 2 is rubber sheaths, and its effect is when rotating with hand, to strengthen frictional resistance.The lower end of extension bar 3 is connected with lock nut 4,5 lockings fastening with splined shaft 17.Splined shaft 17 is connected with clutch 15 usefulness splines.Spring 8 is withheld on clutch 15, and spring 8 one ends are connected the other end and are connected with moment of torsion adjustment nut 7 with clutch 15, and moment of torsion is adjusted 6 lockings of nut 7 usefulness torque lock nuts.Adjust the size of moment of torsion by the pressure of adjusting spring 8.Clutch 14 docks with clutch 15, and they are a pair of press insert type clutches.One end of hitch 16 is connected with clutch 14, and the other end is connected with ratchet assembly overcoat 11,10 lockings of ratchet assembly overcoat 11 usefulness ratchet lock pins, inside and outside cover 13, the 11 rotatable effects that reach the degree of tightness nut of ratchet assembly.The effect of hitch 16 is transfer torques.The lower end that work sleeve 9 is positioned at the ratchet assembly is connected with ratchet assembly cover 13, is connected and fixed with work sleeve alignment pin 12 and ratchet assembly.
When manipulating, with work sleeve 9 be enclosed within need tighten or loosening sleeper nut on, the integral body of turning handle 1 spanner sleeve along ratchet outside rotates, and can or become flexible the big nut screwing clamping of moment of torsion.When need adjusting moment of torsion big or small, adjust moment of torsion on request and adjust nut 7,, realize degree of tightness nut by coupling bar 16 transfer torques.When needs crouching formula is operated, but the nut of release handle 1 interstitial hole unloads lower push rod, and the entire length of spanner is shortened, and just can operate on request.
