Abstract
The utility model provides a be used for TBM constructional survey total powerstation L type bracket which characterized in that: form by a stainless steel round dish, a channel -section steel, a square pipe and a connecting plate, the lower extreme is managed by the side and channel -section steel one end is welded, and square pipe becomes 90 degrees with the channel -section steel, the welding of stainless steel round dish is in the top of the channel -section steel other end, and a whole is constituteed by upper and lower two parts to the connecting plate, and the angle is 104 11/40 " between two parts, the lower part is divided trompil and arc wall and is arrived the upper end of square pipe through bolted connection, the hole on top is used for installing the bolt of section of jurisdiction. This bracket is compared with bracket of the same kind under the prerequisite of guaranteeing stability, lightens 43%~50% weight, has reduced about 12%~18% cost of manufacture, saves operating time, increases the output value.
Description
Technical field
This utility model relates to TBM when construction survey for installing total powerstation and the forward and backward L bracket regarded.
Background technology
Needing to guide with total powerstation in the construction of TBM, along with the continuous driving of TBM, total powerstation is constantly carried out turning station by needs, so needing the working environment stable to total powerstation offer during guiding.In order to reduce cost, reduce operation easier, so devising a kind of for TBM construction survey total powerstation L bracket.
Summary of the invention
Its technology contents is as follows:
It is a kind of for TBM construction survey total powerstation L bracket, it is characterised in that: it is made up of one piece of rustless steel disk, a channel-section steel, a square tube and a connecting plate；Square tube lower end and channel-section steel one end weld, and square tube becomes 90 degree with channel-section steel；Rustless steel disk is welded on the top of the channel-section steel other end, and connecting plate is formed a whole by upper and lower two parts, and between two parts, angle is 104 ° 11 ' 40 "；Lower part perforate and arcuate groove are also bolt-connected to the upper end of square tube；The hole of upper part is used for being installed to the bolt of section of jurisdiction.
L bracket is installed the easiest, and will not be changed by adjacent two endless tube sheet gap spacing and affected, this guarantees the required precision that total powerstation is in operation.
Utilize L bracket of the present utility model, have the advantage that
One, 43%～50% weight is alleviated, it is simple to operation.
Two, decrease channel-section steel, connecting plate manufacturing process is simplified.
Three, time-consuming, increase the output value.
Four, the cost of manufacture of about 12%～18% is reduced.
Accompanying drawing explanation
Fig. 1 is L bracket
Fig. 2 is connecting plate detail structure.
Detailed description of the invention
This utility model is a kind of for TBM construction survey total powerstation L bracket, it is characterised in that use the rustless steel disk (1#) of one piece of 90mm (R) * 6mm (thickness), the channel-section steel that specification is 50 (2#) of root length 380mm, the square hollow section steel that specification is 50 (3#) of root length 309mm and a 27700mm2The connecting plate (4#) of (area) * 10 (thick), gross weight is 7.224kg, and its moulding is as shown in Figure 1.
TBM interval Segment design is general endless tube sheet, is respectively arranged with one cross bolts before and after section of jurisdiction, every endless tube sheet from 0:00 direction every 36 ° have one longitudinal bolt.Being compared by the instrumented site in top left side longitudinal bolt hole, section of jurisdiction and TBM design section figure, we determine instrument bracket to be fixed on this bolt hole.Because longitudinal bolt hole is angled depression to the inside, in order to bracket can be allowed during mounting bracket parallel with section of jurisdiction section, so the angle of the angle longitudinal bolt hole depression of connecting plate design is identical, connecting plate (4#) detail structure such as Fig. 2.
Manufacture method:
(1) with two screws, connecting plate and square tube are coupled together, the most each one.After screw above tightens, it is possible to use the groove on connecting plate carries out the regulation of angle to square tube.
(2) square tube lower end and one section of channel-section steel are welded, become 90 degree.
(3) rustless steel disk is welded on the top of the channel-section steel other end, and between two parties.
Installation method:
(1) choose section of jurisdiction in advance, and find longitudinal segment bolt of 36 ° of positions on section of jurisdiction, with torque spanner, its screw dismounting is fallen；
(2) junction steel plate is put up, and tighten section of jurisdiction screw；
(3) again bracket is bolted on junction steel plate, it is noted that forced centering base whether level during installation, confirm smooth after bolt is tightened.
Bracket installation site and spacing are typically based on tunnel linear and site operation situation selects to determine, instrument bracket be mounted at least shield tail after on section of jurisdiction beyond 10 rings (after requiring this endless tube sheet is carried out slip casting in the case of execution conditions meet, just can measure work) on straightway, we install a bracket according to 50-70m, curved section installs a bracket according to sweep and condition of construction 20-40m, one survey station bracket is often installed, a upper survey station bracket just can be as rearscope bracket, push ahead bracket successively to install, the most every four brackets are one group and can recycle.
