Abstract
The utility model discloses a general forced centring device, which is characterized by comprising a disk and a center screw, wherein the center screw comprises a circular arc head, a metric-system and British-system general thread binding post and a connecting screw; after the connecting screw downwards passes through a center round hole of the disk, the disk is fixed below the metric-system and British-system general thread binding post by a disk fastening nut; the bottom end of the connecting screw of the center screw is provided with a gasket locking nut, a large gasket and a gasket fastening nut; the top of the center screw can be directly provided with metric-system spiral interface observation equipment and British-system spiral interface observation equipment; and the requirements of horizontal displacement and vertical displacement observation projects are given consideration. The general forced centring device has the advantages of low error rate, strong metric-system and British-system popularity, simple structure and low cost, is accurate to observe, is simple to process and is easy to install, maintain and replace. The general forced centring device can be applied to the deformation observation projects of the horizontal displacement and the vertical displacement of other large constructions.
Description
Technical field
The utility model relates to deformation observation equipment, especially relates to the universal pressure centralising device of a kind of reservoir dam and other building deformation observations.
Background technology
The key construction of reservoir engineering is a reservoir dam, and dam safety is related to reservoir engineering safety, also involves the safety of reservoir downstream people life property safety and national basis facility simultaneously.Deformation observation is one of main project of dam safety monitoring, forced centering plate or forced centering pedestal are normally adopted in deformation observation in the past, these two kinds of equipment are complex manufacturing technology, cost price height not only, and installation procedure is loaded down with trivial details, use very trouble, the problem that has more artificial repetitive error, and perpendicular displacement separates with the sign of horizontal shift, also increased the quantity of displacement observation pier, as it is aging to run into instrument damage or instrument, also will consider problems such as the spiral of interface is supporting when needing to change instrument.
Summary of the invention
The purpose of this utility model just provides and a kind ofly observes accurately, error rate is low, metric system, highly versatile made in Great Britain, processing is easy, installation and maintenance are changed and all are easy to, simple in structure, universal pressure centralising device that cost is low.
The purpose of this utility model is achieved in that
A kind of universal pressure centralising device, feature is: be made up of disk and center bolt, centre at disk is processed with center hole, be processed with the circular arc head at the top of center bolt, below the circular arc head of center bolt, be processed with metric system, the general post that is threaded made in Great Britain, metric system at center bolt, the below of general threaded post made in Great Britain is processed with the connecting screw rod of strip, after the connecting screw rod of center bolt is passed down through the center hole of disk, by the disk fastening nut disk is fixed on metric system, the below of the general post that is threaded made in Great Britain is equipped with the pad check nut that is fixed together in the bottom of the connecting screw rod of center bolt, large size pad and pad fastening nut.
Outward flange at disk is processed with hypotenuse, be processed with in the bottom surface of disk can with the frosting that more easily combines of observation pier.
The diameter of metric system, the general post that is threaded made in Great Britain is greater than the diameter of center hole, and the diameter of center hole is greater than the diameter of connecting screw rod.
The utility model is made up of disk and center bolt, it is on the basis of traditional round end bench mark, be processed with the circular arc head at the top of center bolt, below the circular arc head of center bolt, be processed with metric system, the general post that is threaded made in Great Britain, facilitate like this at the top of center bolt metric system spiral interface scope and spiral interface scope made in Great Britain directly are installed, also taken into account horizontal shift and perpendicular displacement observation project demand simultaneously.The utility model adopts split accessory assembling mode, that is: center bolt screws with a disk fastening nut after inserting disk, screw mutually with pad check nut, pad and large size pad fastening nut in the bottom of connecting screw rod then, disk, center bolt and disk fastening nut, pad check nut, pad and pad fastening nut all water in the pier body that is contained in basic point observation pier in advance, can play and the better effect that combines of basic point observation pier, thereby can carry out deformation observation easily.The end face of disk has been taked polishing technology, improved the degree of fiting of card planarization and the utility model and relevant device, outward flange at disk is processed with hypotenuse, is processed with frosting in the bottom surface of disk, can allow the utility model combine better with basic point observation pier.Disk and center bolt all adopt high-intensity 304 stainless steels, thereby can significantly reduce to indicate the error that wearing and tearing and corrosion cause.The utility model both solved horizontal shift and perpendicular displacement unitarity, limited the error of centralization of repetitive operation, construction technique requires simple simultaneously, only need keep the vertical and disc face of center bolt and observe the pier end face flush getting final product, (observation instrument only need be aimed at screw rod and screw on and get final product to have simplified later stage deformation observation running program, other leveling observations are as normal observation), also saved the construction and installation cost of basic point observation pier and the cost of manufacture of forcing centralising device.
Therefore, the utlity model has observation accurately, error rate low, metric system, highly versatile made in Great Britain, processing is easy, installation and maintenance are changed and all are easy to, simple in structure, advantage that cost is low, the utility model also can be applicable to the deformation observation project of the horizontal shift and the perpendicular displacement of other buildings.
