Abstract
The utility model discloses a kind of fixing device for shield section marshaling track, including screw mandrel, one end of the screw mandrel is fixedly welded with along its axially extending rectangle band steel, from it, axially bending is set the rectangle band steel diagonally downward at middle part, the bolt hole to match with shield duct piece bolt is offered on the rectangle band steel bent diagonally downward, engagement sleeves are moved on screw mandrel rail clamping device of rail is housed, adjusting nut is bolted with respectively on the screw mandrel of the rail clamping device of rail both sides.The utility model advantage is to have prevented track lateral shift, twisted phenomena from track laying source, is slided down problem so as to solve marshaling.Meanwhile easy, easily operated, the ratchet spanner of installation tool use fastening fish (-)bolt, without another standby instrument is installed and removed to the utility model.Reach that railway maintenance is convenient, workload is small, location of rail is easy to the purpose of regulation, and avoid and welded on shield duct piece bolt, cut off reinforcing bar caused by bolt damage.
Description
Technical field
Device for fixing running tracks is the utility model is related to, is especially for the fixed dress of shield section marshaling track
Put.
Background technology
In Construction of Urban Rail Traffic, shield method tunnel construction has become each because its is safe, speed of application is fast
The main construction method of urban track traffic constructing tunnel.The fixation of shield section marshaling track, at present using in shield
The method of welded reinforcement is reinforced between segment bolt and rail.But it is larger due to being shaken when marshaling is run, reinforcing bar with
Steel rail welding line is easy to crack, causes track lateral shift, twisted phenomena, causes marshaling to slide down frequently, railway maintenance workload
Greatly, efficiency is low, and shield-tunneling construction risk is big, and when rail is removed, it is necessary to reinforcing bar is cut off one by one, dismantling of track compared with
Slowly；Welded in addition on shield duct piece bolt, cut off reinforcing bar, also reduce the intensity of shield duct piece bolt, not meeting specification will
Ask.
The content of the invention
The utility model purpose is to provide a kind of fixing device for shield section marshaling track.
To achieve the above object, the utility model takes following technical proposals：
Fixing device described in the utility model for shield section marshaling track, including screw mandrel, the screw mandrel
One end is fixedly welded with along its axially extending rectangle band steel, and from it, axially bending is set the rectangle band steel diagonally downward at middle part
Put, offer the bolt hole to match with shield duct piece bolt on the rectangle band steel bent diagonally downward, on screw mandrel
Dynamic engagement sleeves are equipped with rail clamping device of rail, and adjusting nut is bolted with respectively on the screw mandrel of the rail clamping device of rail both sides.
Two adjusting nuts are in contact by packing ring with the rail clamping device of rail respectively.
One end of the rectangle band steel offers neck, and one end of the screw mandrel is connected in the neck and by two-sided
Full weld is fixed.
The utility model advantage is to have prevented track lateral shift, twisted phenomena from track laying source, so as to solve
Marshaling of having determined slides down problem.Meanwhile easy, easily operated, installation tool use fastening is installed and removed to the utility model
The ratchet spanner of fish (-)bolt, without another standby instrument.Reach that railway maintenance is convenient, workload is small, location of rail is easy to adjust
The purpose of section, and avoid and welded on shield duct piece bolt, bolt damage caused by excision reinforcing bar.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
Embodiment
Embodiments of the invention are elaborated below in conjunction with the accompanying drawings, the present embodiment using technical solution of the present invention before
Put and implemented, give detailed embodiment and specific operating process, but protection scope of the present invention is not limited to down
State embodiment.
As shown in figure 1, the fixing device described in the utility model for shield section marshaling track, including 22mm,
Length is 600mm screw mandrel 1, and one end of screw mandrel 1 is fixedly welded with along its axially extending rectangle band steel 2, rectangle band steel from its
Axially bending is set diagonally downward at middle part, is offered on the rectangle band steel 2 bent diagonally downward and shield duct piece bolt phase
The bolt hole 3 of matching, engagement sleeves are moved on screw mandrel 1 rail clamping device of rail 4 be housed, distinguished on the screw mandrel 1 of the both sides of rail clamping device of rail 4
Adjusting nut 5,6 is bolted with, two adjusting nuts 5,6 are in contact by packing ring with rail clamping device of rail 4 respectively.
During actual manufacture, one end of rectangle band steel 2 offers deep 50mm neck, and one end of screw mandrel 1 is connected in neck
And fixed by two-sided full weld.
Application method of the present utility model is：
The one end of rectangle band steel 2 in strap bolt hole 3 is arranged on corresponding shield duct piece bolt first during installation, secondly by silk
Rail clamping device of rail 4 on bar 1 is connected to rail foot, and two adjusting nuts 5,6 are fastened i.e. after adjusting location of rail
Can；Order in contrast, tightens up shield duct piece bolt after dismounting during dismounting.In tunnel two are filled every 12 meter amperes admittedly
Determine device, two fixing devices are symmetrical with the installation of track both sides.
