Abstract
It the utility model is related to measurement and positioning instrument, specially a kind of positioner fixed for track-laying machine rail buttress in circular cross section tunnel, solve the problems, such as to exist during existing rail buttress installation waste time and energy, efficiency of construction is low and positioning accurate parasexuality is poor.A kind of positioner fixed for track-laying machine rail buttress in circular cross section tunnel, including the curved plate coordinated with tunnel cross-section, the positioning hole with rail buttress position correspondence is provided with curved plate, and operating handle is connected with the middle part of the inner surface of curved plate, it is provided with contraposition breach at the base midline position of curved plate.The utility model considerably reduces the labor intensity of worker while saving of work and time, improves the smooth degree of equipment walking rails, can be applicable in similar projects.
Description
Technical field
Measurement and positioning instrument is the utility model is related to, is specially that one kind is used for track-laying machine rail branch in circular cross section tunnel
The positioner that pier is fixed.
Background technology
Subway has turned into the important means of Urban Rapid-Transport, due to the subway tunnel driving using shield excavation machine construction
After be mounted directly section of jurisdiction, form circular cross section, and space is smaller in hole, when carrying out Monolithic Track Bed Construction, need to shift to an earlier date in tube wall
The walking rails for unit of laying a railway track are installed in the cambered surface of bottom.At present, more track travelings being adapted using installation bottom surface with cambered surface
Rail buttress, rail branch socle be in horizontal installation apparatus walking rails after, to support unit weight of laying a railway track.Rail is installed
During buttress, it need to shift to an earlier date and 4 expansion bolts are installed in cambered surface after measurement and positioning, symmetric borehole.
To ensure that the expansion bolt of installation meets the installation requirement of rail buttress, it is necessary to which worker holds rail buttress exists
Aligned in tunnel cambered surface, row drilling again after making a mark, due to the rail nearly 20kg of buttress weight, using such a mode not only work
Imitate that low, labor intensity is big, and positioning accurate parasexuality is not high so that also need to adjust traveling one by one with backing plate after the installation of rail buttress
Rail buttress apical side height, it is time-consuming.
The content of the invention
The utility model in order to exist when solving the installation of existing rail buttress waste time and energy, efficiency of construction is low and positions
A kind of the problem of accuracy is poor, there is provided positioner fixed for track-laying machine rail buttress in circular cross section tunnel.
The utility model is achieved by the following technical solution：One kind is used for track-laying machine rail in circular cross section tunnel
The positioner that buttress is fixed, including the curved plate coordinated with tunnel cross-section, it is provided with and rail buttress position on curved plate
Corresponding positioning hole is put, and operating handle is connected with the middle part of the inner surface of curved plate, at the base midline position of curved plate
It is provided with contraposition breach.
When needing to install the rail buttress for unit of laying a railway track, rail buttress elevation is put using measuring instrument
Sample, and along the axial ejection horizontal linemark in tunnel, then determined according to the clipping room of rail buttress away from marking cross on altitude traverse
Bit line, workmen can hand-held operation handle, curved plate base is alignd with horizontal linemark, while will contraposition breach and cross
Vertical line alignment in position line, is finally labeled the fast positioning that bore position can be achieved using carbon pen to positioning hole.
The problem of wasting time and energy, efficiency of construction is low and positioning accurate parasexuality is poor when overcoming existing rail buttress installation be present.
The utility model is simple in construction, reasonable in design, can be completed by some leftover pieces, be coordinated using the present apparatus
Measuring instrument, the fast positioning that equipment rail buttress is installed on circular tunnel arcwall face is realized, in the same of saving of work and time
When, the labor intensity of worker is considerably reduced, improves the ride comfort of equipment walking rails.The device have improve quality,
Improve work efficiency, reduce the advantages of cost, can be applicable in similar projects.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model；
Fig. 2 is Fig. 1 schematic top plan view.
In figure：1- curved plates, 2- positioning holes, 3- operating handles, 4- contraposition breach.
Embodiment
The utility model is further elaborated with reference to Fig. 1 and Fig. 2, one kind is used for track-laying machine traveling in circular cross section tunnel
The positioner that rail buttress is fixed, including the curved plate 1 coordinated with tunnel cross-section, it is provided with and rail branch on curved plate 1
The positioning hole 2 of pier position correspondence, and operating handle 3 is connected with the middle part of the inner surface of curved plate 1, in the base of curved plate 1
Contraposition breach 4 is provided with line position.
In specific implementation process, using the utility model positioner, single positioning action can be achieved, determine 4 positioning
Hole only needs half a minute, and labor intensity is reduced while greatly improving operating efficiency, improving quality.
