Abstract
The invention provides a switching operation assisting device, comprising two fixed lantern rings and two detachably connected handle sleeves, wherein each fixed lantern ring comprises a positioning-limiting ring which is arranged at one side; each handle sleeve comprises a positioning-limiting hole which is arranged at one side; the positioning-limiting rings are arranged in the handle sleeves; the fixed lantern rings are penetrated in the positioning-limiting holes; and the fixed lantern rings are provided with screw holes. The contact surfaces between the fixed lantern rings and the handle sleeves are smooth contact surfaces. The two handle sleeves are in threaded connection. The switching operation assisting device has the advantages of scientific design, no change of the crank handle structure, convenience in installation and improved working efficiency.
Description
Technical field
The present invention relates to the servicing unit in a kind of crank handle, specifically, related to a kind of grid switching operation servicing unit for crank handle on the Substation Switch Changing Operation isolating switch.
Background technology
On the grid switching operation device of electric power system isolating switch is arranged, the manual-operating mechanism of isolating switch is crank handle, and this crank handle normally is made by stainless steel.All need continuously continual shaking owing to closing or pulling open isolating switch, just isolating switch can be shaken the position of appointment, but insulating gloves and crank handle frictional force are excessive, insulating gloves easily can be wrapped in the crank handle, yet operating personnel can not change manual manipulation in operating process, so not only cause the damage of insulating gloves, hurt operating personnel's hand, in some cases, also can cause damage of equipment and the serious consequence of casualties, formed larger potential safety hazard.
In order to solve the problem of above existence, people are seeking a kind of desirable technical solution always.
Summary of the invention
The objective of the invention is for the deficiencies in the prior art, thereby a kind of design science is provided, need not to change the crank handle structure, easy for installation, the grid switching operation servicing unit of increasing work efficiency.
To achieve these goals, the technical solution adopted in the present invention is: a kind of grid switching operation servicing unit, it comprises two retaining collars and is connected two handle jackets that removably connects, described retaining collar comprises the spacing ring that is arranged on the one side, described handle jacket comprises the spacing hole that is arranged on the one side, described spacing ring is arranged in the handle jacket, and described retaining collar passes described spacing hole setting, is provided with screw on the described retaining collar.
Based on above-mentioned, contact-making surface is smooth contact surface between described Fixing shrink ring and the described handle jacket.
Based on above-mentioned, be threaded between described two described handle jackets.
The relative prior art of the present invention has outstanding substantive distinguishing features and marked improvement, and specifically, the present invention only need be screwed in the crank handle and get final product, and need not to change the crank handle structure, prevents because the hidden danger that improper repacking brings; Main body is sleeve pipe and helicitic texture, only can fix with screw, and is easy for installation; Utilize the rotation of handle jacket on retaining collar, solved the problem that insulating gloves is wound, improved operating efficiency.This grid switching operation servicing unit has advantages of design science, need not to change the crank handle structure, easy for installation, increase work efficiency.
Description of drawings
Fig. 1 is structural representation of the present invention.
Among the figure: 1. Fixing shrink ring; 2. handle jacket; 3. spacing ring; 4. screw; 5. operating crank.
Embodiment
Below by embodiment, technical scheme of the present invention is described in further detail.
As shown in Figure 1, a kind of grid switching operation servicing unit, it comprises two retaining collars 1 and is connected two handle jackets 2 that removably connects, described retaining collar 1 and described handle jacket 2 preferred metal materials also can be other suitable materials.Described retaining collar 1 comprises the spacing ring 3 that is arranged on the one side, the internal diameter of described retaining collar 1 is greater than the diameter of operating crank 5, described handle jacket 2 comprises the spacing hole that is arranged on the one side, described spacing ring 3 is arranged in the handle jacket 2, described retaining collar 1 passes described spacing hole setting, be provided with screw on the described retaining collar 1, it also can be several that described screw can be one.
Contact-making surface is smooth contact surface between described Fixing shrink ring 1 and the described handle jacket 2, and the purpose of design is for the power of reducing friction like this, and described handle jacket can freely be rotated on described Fixing shrink ring.
Be threaded between described two described handle jackets 2, be threaded to preferred version, also can comprise the connected mode that other are suitable.
The mounting means of this grid switching operation servicing unit is: two described retaining collars 1 are installed in respectively in two described handle jackets 2 as shown in Figure 1, two described handle jackets 2 are linked to be a handle jacket by screw thread, then described operating crank 5 is inserted in described retaining collar 1 and the described handle jacket 2, then with in the described screw of screw 4 precessions, until described screw 4 withstands operating crank 5.Described screw 4 is tightened, and described retaining collar 1 just has been fixed on the described operating crank 5.
Should be noted that at last: above embodiment is only in order to illustrate that technical scheme of the present invention is not intended to limit; Although with reference to preferred embodiment the present invention is had been described in detail, those of ordinary skill in the field are to be understood that: still can make amendment or the part technical characterictic is equal to replacement the specific embodiment of the present invention; And not breaking away from the spirit of technical solution of the present invention, it all should be encompassed in the middle of the technical scheme scope that the present invention asks for protection.
