Description
Technical field
The utility model relates to power system repair apparatus, particularly a kind of spanner for erection unit.
Background technology
In the time high-tension apparatus being carried out to interruption maintenance or carries out other work, for prevent equipment send a telegram here suddenly, release power cutoff device residual charge and prevent that contiguous high voltage alive equipment from producing induced voltage human body is worked the mischief, earth connection need to be first installed, and this is the important safety guarantee to operating personnel in power transformation grid switching operation process.The mode of mounting or dismounting earth connection is generally to be completed by operating personnel's free-hand (wearing insulating glove) at present, due to shortage instrument, need to hold drop bar, and ceaselessly fast, firmly twist wrist.According to current operant level, complete the dress of one group of earth connection or tear open, approximately need 10 minutes, wherein reverse three drop bar needs consuming time clock more than 6 points.According to general situation, wrist does not stop to twist 4 minutes, arm muscle there will be tighten, numb situation.Therefore such a earth connection operation, can cause operating personnel's arm muscular strain, thereby affect follow-up operating efficiency.
Summary of the invention
Based on this, the utility model is to overcome the defect of prior art, and a kind of spanner is provided, and makes all more convenient and quicker of installation and removal of earth connection.
Its technical scheme is as follows:
A kind of spanner, comprise handle, tightening latch and the cuff being connected with handle, cuff comprises the first semi-ring and the second semi-ring, one end of one end of the first semi-ring and the second semi-ring is bolted, the first semi-ring, the second semi-ring can rotate around the axial line of bolt respectively, the other end of the first semi-ring, the other end of the second semi-ring are respectively equipped with connectivity port, and connectivity port is provided with hole, and tightening latch comprises the bar suitable with hole.
Below further technical scheme is described:
Described handle is connected with described the first semi-ring.
Described bar is threaded rod, in the hole of described the second semi-ring connectivity port, is provided with nut, and nut and described bar are suitable.
Described tightening latch also comprises the rotating handles being connected with bar, and described rotating handles is connected with described bar by approach screw, and rotating handles is provided with groove at connecting portion, and rotating handles can rotate by groove on bar.
Described bar is provided with elastomeric pad at the position near rotating handles.
Described handle is provided with anti-slip veins.
Below principle, the effect etc. of aforementioned techniques scheme are described:
The cuff that this spanner consists of the first semi-ring and the second semi-ring can be waled drop bar, make it locking by tightening latch again, staff just can carry out the installation or removal work of this drop bar by the handle of operation spanner, degree of holding with a firm grip is higher than free-hand grasping on the one hand, can not skid, reduce consumption power by the lever principle of handle on the other hand, thereby can alleviate widely staff's energy consumption, can promote widely again operating efficiency, work is got twice the result with half the effort.

Detailed description of the invention
Below embodiment of the present utility model is elaborated:
As shown in Figure 1 to Figure 3, for a kind of spanner that is applicable to earth connection Fast Installation and dismounting, comprise handle 10, tightening latch 40 and the cuff being connected with handle, handle 10 is provided with anti-slip veins, cuff comprises the first semi-ring 20 and the second semi-ring 30, handle 10 and the first semi-ring 20 weld together, one end of the first semi-ring 20 is connected by bolt 11 with one end of the second semi-ring 30, form an annulus that can carry out folding around bolt 11 axial lines, the other end of the first semi-ring 20, the other end of the second semi-ring 30 is made as respectively the first connectivity port 21, the second connectivity port 31, the first connectivity port 21 and the second connectivity port 31 are provided with hole, tightening latch 40 comprises the bar suitable with hole 41, bar 41 is threaded rod, in the hole of the second connectivity port 31, be provided with the nut 42 suitable with bar 41, when bar 41 is during through nut 42 in hole 22 and second connectivity port 31 of the first connectivity port 21, just the opening degree of adjustable the first semi-ring 20 and the second semi-ring 30, tightening latch 40 also comprises the rotating handles 43 being connected with bar 41, rotating handles 43 is connected with bar 41 by approach screw, rotating handles 43 is provided with groove 44 at connecting portion, rotating handles 43 can rotate by this groove 44, in figure, " close " direction is locking direction, bar 41 is also provided with elastomeric pad 45 at the position near rotating handles, to prevent that rotating handles 43 and tightening latch 40 parts such as grade from wearing and tearing.
Staff is in the time of installation or removal earth connection, first the first semi-ring 20, the second semi-ring 30 are waled to drop bar, again tightening latch 40 is revolved through the nut 42 in hole 22 and second connectivity port 31 of the first connectivity port 21, regulate suitable elasticity, finally rotating handles 43 is locked along " close " direction.Then just can carry out the installation or removal work of drop bar by operating grip 10.After finishing the work, untie rotating handles 43, unscrew the cuff that the first semi-ring 20 and the second semi-ring 30 form, just spanner can have been taken off.Operate by this spanner, degree of holding with a firm grip, higher than free-hand grasping, can not skid on the one hand, can reduce consumption power by the lever principle of handle on the other hand, thereby can alleviate widely staff's energy consumption, can promote widely again operating efficiency, work is got twice the result with half the effort.
The above embodiment has only expressed detailed description of the invention of the present utility model, and it describes comparatively concrete and detailed, but can not therefore be interpreted as the restriction to the utility model the scope of the claims.It should be pointed out that for the person of ordinary skill of the art, without departing from the concept of the premise utility, can also make some distortion and improvement, these all belong to protection domain of the present utility model.
