Description
Technical field
The present invention relates to power supply maintenance of equipment, specifically it is a kind of it is easy to operate, work efficiency is high, it is real to be exclusively used in disassembly
Heart pin, out of stock, taper bolt pin removal device.
Background technique
It is well known that the power supply units such as high-tension switch cabinet, ammeter box are especially existed using the connection of a large amount of pin, locking
Pin is widely used in the processing of the metal die and heavy parts of some large sizes.The citation form of pin is by straight pin or circle
Taper pin, wherein straight pin is fixed in pin hole using micro interference, and taper bolt then leans on conical surface squeezing action to be fixed in pin hole.
Under normal circumstances, for the connection of thick-walled parts, pin is fitted in blind hole.Electrical component, transmission of electricity in power industry
Route insulator after long-play will appear self-destruction, zero, flashover equivalent damage situation, need to replace insulator,
Insulator model is numerous, structure is different, and part insulator locking pin is not drawn out easily in replacement process.Since pin usually has carbon
Steel or alloy steel making, surface is by quenching treatment, but core is softer.During installation, if firmly tapped using hammer, can make
Pin is deformed at bottom, and disassembly is hit with hammer opposite direction again, and deficiency is to be easy to cause mechanical adjacent parts
Loosening or damage, in strike if punching pin slip, easily cause the damage and personal injury of firmware.In addition, due to narrow
Small space is not also easy to operate, and working efficiency is low, high to the technical requirements of operator.
Summary of the invention
The purpose of the present invention is overcoming above-mentioned the deficiencies in the prior art, provide it is a kind of it is easy to operate, work efficiency is high, dedicated
In disassembly, out of stock, taper bolt pin removal device.
The present invention can be reached by following measure：
A kind of pin removal device, it is characterised in that be equipped with fixing seat and support rod, fixing seat and support rod one end are corresponding
Ground is equipped with connecting rod, and the front end of a connecting rod is equipped with forward screw thread, and the front end of another connecting rod is equipped with reverse thread, and two connect
Extension bar is connected through fastener, and fastener is equipped with bow-shaped support, and the both ends of bow-shaped support are respectively equipped with nut, and support rod is equipped with
Positioning sleeve and fixture nut, fixing sleeve side are equipped with positioning screw hole, and compartment of terrain is equipped with positioning groove in locating rod, and locating rod passes through
Fixing sleeve lower end is equipped with positioning disk, and the located bolt of locating rod and positioning screw hole positioning, dismantling screw are connected through screw thread with nut
It connects, dismantling screw lower end is equipped with ejector pin clamp, and thimble is equipped in fixture, and the fixing seat below thimble is equipped with removal hole, disassembly
Screw rod upper end is equipped with rotating handle.
Locating rod of the present invention is equipped with metering scale groove, to facilitate operation working efficiency is improved.
The present invention is in use, carry out just positioning through fixing seat and locating rod first, then positioned by fastener, then
It by thimble face pin and rotates rotating handle and ejects pin, have the advantage that effect is as follows：（1）Securely and reliably, easy to operate.No
The strong momentum tool such as hammer, punching is reused, avoids personal equipment damage, and reduce the requirement skilled to staff's technical ability.
（2）Uniform force, it is time saving and energy saving, with the labor operation for avoiding high intensity.（3）It is light portable, it is made of steel alloy, and
Tool is simple, convenient for assembly and disassembly.
Detailed description of the invention
Fig. 1 is a kind of structural schematic diagram of the invention.
Specific embodiment
The invention will be further described below in conjunction with the accompanying drawings：
As shown, a kind of pin removal device, it is characterised in that be equipped with fixing seat 1 and support rod 2, fixing seat 1 and branch
2 one end of strut is accordingly equipped with connecting rod 3 and 4, and the front end of connecting rod 3 is equipped with forward screw thread, and the front end of connecting rod 4 is equipped with
Reverse thread, two connecting rods are connected through fastener 5, fastener 5 be equipped with bow-shaped support, the both ends of bow-shaped support be respectively equipped with
The nut that connecting rod 3 and 4 matches, support rod 1 are equipped with positioning sleeve 6 and fixture nut 7, and 6 side of fixing sleeve is equipped with positioning spiral shell
Hole, compartment of terrain is equipped with positioning groove in locating rod 8, and locating rod 8 passes through 6 lower end of fixing sleeve and is equipped with positioning disk 9, and locating rod 8 is through fixed
Position bolt 10 and positioning screw hole positioning, dismantling screw 11 are connected through screw thread with nut 7, and 11 lower end of dismantling screw is pressed from both sides equipped with thimble
Tool 12, ejector pin clamp 12 is interior to be equipped with thimble 13, and the fixing seat 1 of 13 lower section of thimble is equipped with removal hole, and 11 upper end of dismantling screw is set
There is rotating handle 14, in addition, locating rod of the present invention 8 is equipped with metering scale groove, to facilitate operation raising will make efficiency.
The present invention is in use, carry out just positioning through fixing seat and locating rod first, then positioned by fastener, then just by thimble
It to pin and rotates rotating handle and ejects pin, have the advantage that effect is as follows：First is that safe and reliable, easy to operate.It does not use
The strong momentum tool such as hammer, punching, avoids personal equipment damage, and reduce the requirement skilled to staff's technical ability；Second is that by
Power is uniform, time saving and energy saving, with the labor operation for avoiding high intensity；Third is that it is light portable, it is made of steel alloy, and tool
