Background technology
In recent years, domestic city Rail Transit System obtains development at full speed, and the trip for people provides the most just
Profit.Fastener is the important component part of track structure, it is achieved that rail and the connection of railway roadbed, supports simultaneously and fixes rail.Rail
Road structure construction mode is ground and assembles section of track structure, is transported to job site and carries out the adjustment of circuit geometry state and cast coagulation
Soil.Use top-down form of construction work when the section of track assembles, the most first the connection by Damping fastening Yu rail will certain length
Rail and Damping fastening be installed as one.Again rail is installed with Damping fastening and be fixed on by the way of anchor bolt is fixing
On sleeper, form the section of track structure of stagewise；It is transported to section of track structure good for sectional lay place, will be provided with the most again
The sleeper of rail connects as one with railway roadbed basis；Or, Damping fastening segmentation is installed, and Damping fastening and sleeper are installed as one
After, then the rail of certain length and corresponding Damping fastening are installed as one；Last the most again by be provided with the sleeper of rail with
Railway roadbed basis connects as one；In the step carrying out spring and withholding rail, first rail is placed on Damping fastening；Due to
The length of rail is longer, heavier-weight, rail can be considered as fixed body at the scene during construction；Carry out the peace of spring the most again
Dress；When spring be e type and PR etc. draw in formula spring time, in e type and PR etc. draw in the installation process of formula spring, workman uses bullet
Spring is drawn in fastening elastic rod hole by the instruments such as bar pull bar, makes it enter as then tapped spring tail end with weight when running into difficult installation spring
Position；During spring is drawn in or tapped, owing to the asymmetric of fastener stress and fastener are relatively light, can produce the biggest by contacting piece
Torsional moment, thus cause the torsigram 8 between Damping fastening and rail be given between Damping fastening and rail reverse knot
Structure schematic diagram；In work progress, the torsion of fastener or rail easily causes rubber blanket skew and spring unbalance stress under rail at the scene
Phenomenon, cause the change of Damping fastening rigidity, add the potential safety hazard of fastener.
Summary of the invention
For in above-mentioned prior art by relatively light due to the asymmetric of fastener stress and fastener during fastener for installing spring,
The biggest torsional moment can be produced by contacting piece, thus cause the torsion between Damping fastening and rail and there is asking of complete hidden danger
Topic, the present invention provides a kind of device preventing fastening elastic rod from twisting when installing.
For solving above-mentioned technical problem, the technical solution used in the present invention is:
A kind of device preventing fastening elastic rod from twisting when installing, this device includes supporting base and multiple for attachment fastener
The bearing groove of base plate, the plurality of bearing groove is fixedly installed on support base；Described bearing groove be provided with loading plate, shoulder block and
