Urban track traffic is China's independent research with compression-type double-layer vibration damping fastener, the new product with independent intellectual property right, it is widely used on overhead, the underground and ground line of urban track traffic, applicability is very strong, the vibration and noise reducing section of using this fastener to lay, have than the vibration and noise reducing performance of common city rail fastener excellence, urban track traffic field is widely used at home.Its compression-type Damping fastening body has adopted separate type, by upper strata iron chair, intermediate rubber backing plate, lower floor's iron chair, nylon jacket and retaining ring, combined, this patented technology has solved being connected in series between upper and lower layer iron chair and intermediate rubber backing plate dexterously, and can effectively transmit all directions load.
In actual use, by using nylon jacket to make upper and lower layer iron chair and intermediate rubber backing plate in short transverse wedging, then squeeze into the retaining ring that adopts wedge-shaped design, by being interference fitted in two the upper and lower layer of in-plane wedging iron chairs, make fastener body become as a whole.This structure is being produced the employing special mechanical equipment assembling of Shi You factory, once wedging, owing to having adopted interference fit, is difficult to dismounting.But after fastener is laid on the line, once effectiveness in vibration suppression weakens, need to keep in repair, while changing intermediate rubber backing plate, fastener body must be taken apart.But owing to there is no specialized hand handling instrument, cannot dismantle, assemble, often integral body is scrapped, caused very large waste, strengthened the maintenance cost of circuit.
For the problems referred to above, necessaryly provide a kind of Quick-disassembling tool, to overcome described defect of the prior art.
Utility model content
The purpose of this utility model is to overcome the deficiencies in the prior art, and a kind of retaining ring demounting tool is provided.
The utility model is achieved through the following technical solutions: retaining ring demounting tool, comprise four claws, some bearing pins, fixed support, adjusting nut, slide bar, slip ring, two handles and terminal pad, fixed support is H shape support, terminal pad is I shape terminal pad, terminal pad is located on support bracket fastened cross bar, four of terminal pad end angles are respectively equipped with a through hole, and by the bearing pin claw that is articulated and connected, each bearing pin is through the mesopore of claw and the through hole of terminal pad respectively.
Slide bar lower end is fixedly connected with terminal pad, slide bar middle part is provided with square opening, and the handle head of handle is embedded in square opening, the bearing pin that the two ends, left and right of H shape support arrange by the handle middle part respectively handle 8 that is articulated and connected, slip ring is placed on slide bar, and is positioned at square opening upper end; Adjusting nut is connected with slide bar, and is positioned on slip ring 7, is symmetrical arranged two connecting axles on the outer shroud of slip ring, and every two claws are fixedly connected with a connecting axle by the apical pore of claw respectively.
As the further optimization of such scheme,
describedslide bar upper end arranges sinistral external thread, the built-in levogyrate inner thread of adjusting nut, and adjusting nut is threaded with slide bar upper end.
The utility model has the following advantages compared to existing technology: retaining ring demounting tool of the present utility model, instrument is simple, be easy to carry about with one, realization at circuit maintenance scene to the rapid-maintenance of double-layer vibration damping fastener and quick-replaceable, reduce the application cost of fastener, improved the economy that Damping fastening is used.
Accompanying drawing explanation
Fig. 1 is the structural representation of retaining ring demounting tool of the present utility model.
Fig. 2 is the structural representation that sheds outside claw of retaining ring demounting tool of the present utility model.
The specific embodiment
Below embodiment of the present utility model is elaborated; the present embodiment is implemented take technical solutions of the utility model under prerequisite; provided detailed embodiment and concrete operating process, but protection domain of the present utility model is not limited to following embodiment.
Referring to Fig. 1-Fig. 2, retaining ring demounting tool comprises four claws 10, some bearing pins 11, fixed support 9, adjusting nut 6, slide bar 12, slip ring 7, two handles 8 and terminal pads 13, fixed support 9 is H shape support, terminal pad 9 is I shape terminal pad, terminal pad 13 is located on the cross bar 91 of fixed support 9, four end angles of terminal pad 13 are respectively equipped with a through hole, and bearing pin 11 is through the mesopore of claw 10 and the through hole of terminal pad 13, and four claws are articulated and connected.
Slide bar 12 lower ends are fixedly connected with terminal pad 13, slide bar 12 middle parts are provided with two square openings, and the handle head of two handles 8 is embedded in square opening, the bearing pin that the two ends, left and right of H shape support arrange by the handle middle part respectively handle 8 that is articulated and connected, slip ring 7 is placed on slide bar 12, and is positioned at square opening upper end; Adjusting nut 6 is connected with slide bar 12 upper ends, and is positioned on slip ring 7, is symmetrical arranged two connecting axles on the outer shroud of slip ring 7, and every claw 8 is fixedly connected with a connecting axle by the apical pore of claw respectively.
