Description
Technical Field
The utility model belongs to the technical field of engineering tunnel construction of water conservancy and hydropower, highways, railways and the like, and particularly relates to a hanging and fixing device for a TBM tunnel construction measuring instrument.
Background
In the TBM construction process of projects such as water conservancy and hydropower, highways, railways and the like, equipment tunneling guidance is very important, and the equipment tunneling state must be monitored constantly to ensure normal tunneling. The method is characterized in that a total station is generally adopted for measuring and a VMT guide control system is combined for monitoring the tunneling state, the traditional measuring method cannot be used due to the limitation of the structural complexity of TBM equipment, on-site measuring equipment needs to be hung on a hole wall for measuring, but a traditional triangular support cannot be used, only one platform can be temporarily manufactured and hung on the hole wall, the temporarily manufactured platform cannot guarantee the balance and the stability of the platform, larger measuring errors can be caused, frequent checking is needed, time and labor are wasted, the construction efficiency is low, and the normal tunneling of the TBM cannot be guaranteed.
Therefore, it is necessary to provide a TBM tunnel construction measuring instrument hanging and fixing device, simple structure, high efficiency of construction, durable, repeatedly usable, solve in the TBM work progress measuring instrument suspend in midair fixed unstability cause measuring error big, can't satisfy the normal tunnelling construction scheduling problem of TBM.
SUMMERY OF THE UTILITY MODEL
In order to solve the problems that in the prior art, the measurement error is large and normal tunneling construction cannot be met due to unstable suspension of a measuring instrument in the TBM construction process, the utility model provides the hanging and fixing device for the measuring instrument in the TBM tunnel construction, which has the advantages of simple structure, high construction efficiency, durability and reusability, and solves the problems that in the TBM construction process, the measurement error is large and normal tunneling construction cannot be met due to unstable suspension and fixation of the measuring instrument.
In order to realize the purpose, the utility model is realized by the following technical scheme:
the utility model provides a hanging and fixing device for a TBM tunnel construction measuring instrument, which comprises an expansion bolt 1, a fixing nut 2, a hanging device connecting rod 3 and a measuring instrument mounting and fixing disk 4; the measuring instrument installation fixing disc 4 on evenly encircle and be fixed with cable suspension device connecting rod 3, the both ends of cable suspension device connecting rod 3 are buckled, one end is fixed at the border of measuring instrument installation fixing disc 4, establish the mounting hole on the other end, expansion bolts 1 passes the mounting hole, the bottom is fixed through fixation nut 2.
Preferably, a gasket 5 is provided between the fixing nut 2 and the hanger connecting rod 3.
The utility model has the beneficial effects that:
the utility model has simple structure, high construction efficiency, durability and reusability, and solves the problems of large measurement error, incapability of meeting the normal tunneling construction of the TBM and the like caused by unstable suspension and fixation of the measuring instrument in the TBM construction process.
