Abstract
The invention provides a self-centering hole adapter. The self-centering hole adapter has high stability when used for installing a prism fixedly. The self-centering hole adapter comprises a hollow base, wherein a spring and a core shaft are arranged in the hollow inner part of the base; a positioning cone is arranged on the lower part of the core shaft; and the spring is sleeved on the core shaft and is positioned at the upper end of the positioning cone. In the self-centering hole adapter, an installation device for the prism is arranged by utilizing bolt holes for arranging rail fasteners directly, so that the error of the spatial attitude, which is reflected by the prism, of rail plates can be reduced to the minimum; and the self-centering hole adapter is close to the bolt holes, so the relationship between the central position of the prism and the bolt hole is stable. Simultaneously, the self-centering hole adapter is small in volume, and the influence of ambient temperature on the stable relation is limit, so the relation is not needed to be checked in the using process; and the self-centering hole adapter can be matched with the bolt holes on different rail plates and can be used for measuring the rail plates and also can be used in other fields.
Description
Technical field
The present invention relates to a kind of pore adapter, particularly relate to a kind of self-centering pore adapter.
Background technology
Plate-type slag-free orbit is a kind of track structure of less maintenance, it utilizes double prestressed concrete track plate and emulsification asphalt cement mortar to substitute the sleeper and the bulk solid ballast aggregate of traditional ballasted track, wheel track power is evenly distributed and be delivered on the roadbed basis, be widely used on the high speed railways such as inter-city rail transit, Line for Passenger Transportation, passenger-cargo mixed transport line road.In the construction of board-like no slag track, need be with the accurate setting-out of track plate to design load, the locus of track plate can be reflected by a plurality of prisms of fixing with track plate geometrical relationship.Prism and track plate geometrical relationship are fixed two kinds of methods are generally arranged: 1) use wooden tripod fixed installation prism, tripod is placed on the track plate and measures on the desired position; 2) use the higher special-purpose metal frame of machining accuracy, prism is fixedly mounted on the frame, frame is placed in the track plate and measures on the desired position.There is following shortcoming in these two kinds of methods: the volume of tripod and frame is bigger, and environment temperature is bigger to its stability influence, in use needs to carry out calibration.
At present the locator data of the track plate of plate-type slag-free orbit all derives from and is used for the bolt hole of attachment rail fastener, though there is multiple template at present, different templates difference to some extent in bolt hole aperture and pore size distribution, the bolt hole of all templates all is a locating hole.
Summary of the invention
Technical problem to be solved by this invention provides a kind of self-centering pore adapter, during with its fixed installation prism, and good stability.
The technical scheme that technical solution problem of the present invention is adopted is: the self-centering pore adapter, the pedestal that comprises hollow is provided with spring and mandrel in the hollow inside of described pedestal, and described mandrel bottom is the location cone, described spring housing and is positioned at cone upper end, location on mandrel.
The invention has the beneficial effects as follows: the present invention directly utilizes the bolt hole of attachment rail fastener that the placing device of prism is set, and can make the error by prism reflection track plate spatial attitude drop to minimum; Pore adapter of the present invention is near bolt hole, so the position at prism center and the relation of bolt hole are highly stable, because the pore adapter volume is little, environment temperature is also very limited to the influence of this stable relation, so in use do not need this relation is carried out calibration simultaneously; Pore adapter of the present invention can mate with the bolt hole on the different track plates, and the present invention simultaneously just is not used for the measurement of track plate, can be used for other field yet.
Description of drawings
Fig. 1 is a sectional view of the present invention.
Fig. 2 is the sectional view of another kind of structure of the present invention.
The specific embodiment
As shown in Figure 1, self-centering pore adapter of the present invention comprises the pedestal 1 of hollow, and the lower plane of described pedestal 1 is vertical with the axis of pedestal 1.Be provided with only screw 2, spring 3 and mandrel 4 in the hollow inside of pedestal 1, described mandrel 4 bottoms are location cone 5, and described spring 3 is enclosed within on the mandrel 4, and is positioned at cone 5 upper ends, location, ends screw 2 and is fixed on mandrel 4 upper ends.The internal cavity of described pedestal 1 is up-narrow and down-wide structure, is divided into epicoele 6 and cavity of resorption 7, described spring 3 and end screw 2 and be arranged in epicoele 6, and mandrel 4 runs through epicoele 6 and cavity of resorption 7, and location cone 5 is arranged in cavity of resorption 7.
Be provided with cross recess or flat recess ending screw 2 upper ends, screwdriver can by cross recess or flat recess control end screw 2 about, thereby controlled core spindle 4 about, and then the tightness of control spring 3.
Above-mentioned location cone 5 shapes are relevant with the size range in the hole that will mate required for the present invention, the size range broad in Pi Pei hole if desired, and the tapering of location cone 5 can be greatly; Otherwise the tapering of location cone 5 can be smaller.Also can adapt to different apertures by the present invention of a plurality of different sizes of configuration.
The upper end of the epicoele 6 of said base 1 preferably is provided with magnet 8, and the effect of magnet 8 is in order to adsorb prism 9, with the convenient stable prism 9 of placing.
During use, the location cone 5 of pore adapter is put into the bolt hole 10 of track plate 11, as shown in Figure 2, and guaranteed the vertical relation of pore adapter and track board plane; Adapt to different bolt apertures by location cone 5 stretching in cavity of resorption 7.And then just can begin to have measured after prism 9 being placed on the upper end of pore adapter, because pore adapter is a hollow structure, therefore, prism 9 can not shake after being placed on the upper end of pore adapter.The upper end of the location cone 5 of pore adapter shown in Figure 2 is provided with groove 12, to make things convenient for the setting of spring 3, can shorten height of the present invention like this, helps reducing cost.
The present invention just is not used for the measurement of track plate, can be used for other field yet, so long as the present invention is used for coupling with the hole, all belongs to protection scope of the present invention.
