Description

Special installation tool for wedge wire clamp

Technical field: the utility model relates to a kind of erecting tools of wedge type clamp.

Background technology: when the branch connection of electric power cable, often will use wedge type clamp, wedge type clamp is made up of wedge type clamp and voussoir, during connection two cables are split on wedge type clamp both sides, push voussoir, utilize the general rifle firing device of peace that voussoir and wedge type clamp are compressed then and produce firm being connected.Adopt the gunpowder percussion to promote but pacify general rifle firing device, not only the sound is big, and certain danger is arranged, and operate, carry etc. must be undertaken by the professional.The effect of gunpowder percussion promotion voussoir is also unstable, and voussoir is pressed too tight or too loosely easily, can't adjust, and installation quality is unreliable.

Summary of the invention: at the deficiencies in the prior art, the utility model provides a kind of special installation tool for wedge wire clamp easy to operate and safe.

The utility model comprises that fixed handle and screw thread are movably connected in the eave tile of end, be provided with oil storage chamber, piston rod and hydraulic system in the fixed handle, the top of piston rod passes fixed handle front end and eave tile corresponding matching, fixed handle also is hinged with flexible handle, the drive rod of this flexible handle and hydraulic system is connected, and constitutes hand-hydraulic formula erecting tools.

The utility model only need back and forth be pulled flexible handle when fitting operation, utilize hydraulic system that piston rod is slowly ejected, piston rod can be stable like this is pressed into voussoir the wedge type clamp, position and degree of tightness pressure can both be controlled reliably, install effective, and operate and carry very handy and safe, need not the professional, rational in infrastructure reliable.

Further specify the utility model below in conjunction with drawings and Examples.

Description of drawings: Fig. 1 is the main structure schematic diagram of embodiment;

Fig. 2 is the vertical view of Fig. 1;

Fig. 3 is the A-A profile of Fig. 1.

Embodiment: as shown in the figure, fixed handle 1 end flexibly connects eave tile 2, generally adopts screw thread to flexibly connect, and changes to rotate all to make things convenient for.Be provided with oil storage chamber 4, piston rod 5 and hydraulic system in the fixed handle 1.The top of piston rod 5 passes fixed handle 1 front end and eave tile 2 corresponding matching, and fixed handle 1 also is hinged with flexible handle 3, and the drive rod 6 of this flexible handle 3 and hydraulic system is connected.Oil storage chamber 4 in the hydraulic system of present embodiment is divided into two parts, the piston rod 5 that is with back-moving spring 7 is placed in one in the right part, two part oil storage chambers 4 are communicated with by oil duct 8, the two ends of oil duct 8 are equipped with unidirectional valve 9 and 10 respectively, drive rod 6 ends are then oblique to be penetrated in the oil duct 8, also be provided with feather valve 11 in the oil duct 8, itself and unloading knob 12 are connected.

When wedge type clamp is installed, two cables 14 to be connected are placed both sides in the wedge type clamp 15 respectively, push voussoir 13, be put in the eave tile 2 again, wedge type clamp 15 front ends withstand eave tile 2.Back and forth pull flexible handle 3 then, when drive rod 6 is upwards drawn, oil duct 8 cavity volumes of drive rod 6 lower ends increase and form parital vacuum, at this moment unidirectional valve 9 is opened, and the oil of left side oil storage chamber 4 is inhaled into oil duct 8, when drive rod 6 presses down, unidirectional valve 9 is closed, unidirectional valve 10 is opened, and oil is pressed in the right side oil storage chamber 4, and plug cock bar 5 ejects.During pull-up drive rod 6, unidirectional valve 10 is closed once more, and piston rod 5 can rollback, back and forth operation, and piston rod 5 can slowly push into voussoir 13 needs the position, easily control.When outwarding winding unloading knob 12, feather valve 11 unclamps, and oil duct 8 is communicated with, and piston rod 5 is rollback under back-moving spring 7 effects, and oil also is retracted in the oil storage chamber 4 in left side, takes out wedge type clamp then and can finish installation.Present embodiment also can install special dismounting spare additional as required, can utilize spring base 5 alive that voussoir 13 is withdrawed from from wedge type clamp 15 equally, is convenient to adjust.
