Description
Technical field
The present invention relates to a kind of built-in fitting positioner, relate in particular to a kind of device that is used for positioning and resisting flotation of embedded part of track slab.
Background technology
At present, the embedded part of track slab location adopts reference column to be tightened in the interior mode of built-in fitting, reference column is fixed on the die surface, when concreting re-packed, railway plate die was under the effect of oscillator, and built-in fitting is swung by vibration, thereby make track built-in fitting come-up, in the concrete meeting injection built-in fitting, and built-in fitting is tilted, make the track blackboard newspaper useless, above-mentioned locate mode, workload is big, and is too loaded down with trivial details, easily produces the pin that stretches tight, built-in fitting floats easily, the quality of track plate can not be protected like this, and working strength of workers is big, efficient is low, complex structure, the cost height can't adapt to present development of high-tech fully.
Summary of the invention
The present invention provides a kind of device that is used for positioning and resisting flotation of embedded part of track slab for solving the technical problem that exists in the known technology, and this device can be avoided the built-in fitting come-up, and is swift and convenient to operate, and the location is reliable, and the track plate quality of shaping is good.
The technical scheme that the present invention takes for the technical problem that exists in the solution known technology is: a kind of device that is used for positioning and resisting flotation of embedded part of track slab, comprise the reference column affixed with the railway plate die bed die, described reference column top is provided with radially pin-and-hole, an end is equipped with the anti-floating pin other end and is equipped with and calms down screw in the described radially pin-and-hole, and described anti-floating pin and described calming down are clamped with spring between the screw; Described anti-floating pin is provided with and extends to outside the described pin-and-hole and the end of the adaptive chucking of built-in fitting screw thread.
Described reference column middle part is provided with annular groove, in the described annular groove sealing ring is installed.
With described railway plate die bed die joint sealing ring is being installed on the described reference column.
Advantage and good effect that the present invention has are: adopt the structure that chucking anti-floating pin and sealing ring are installed between reference column and built-in fitting, the problem of having avoided built-in fitting to be vibrated and swing, float, built-in fitting accurate positioning, track plate forming quality are easy to ensure; Be screwed into mode by rotation and just built-in fitting can be tightened on the bed die, the efficient height can alleviate manual labor, hommization; And the present invention is simple in structure, and is easy to use, and cost is low.

The specific embodiment
For further understanding summary of the invention of the present invention, characteristics and effect, exemplify following examples now, and conjunction with figs. is described in detail as follows:
As shown in Figure 1, the present invention is a kind of device that is used for positioning and resisting flotation of embedded part of track slab, comprises the reference column 2 affixed with the bed die 10 of railway plate die, establishes anti-floating pin 3 on the reference column, and spring pin 3 tightly is stuck in the screw thread of built-in fitting 1.Reference column 2 adopts screw threads for fastening to be connected with railway plate die bed die 10, tightens up below by nut 8, packing ring 9.Easy for installation, need not operating mechanism, disposable connecting gets final product, and only mould need be pulled up during dismounting to get final product, and reference column 2 still is fastened on the bed die 10, can not leave with mould.Reference column 2 is provided with O RunddichtringO 5 with the joint of bed die 10, increases the steadiness and the sealing that connect.
As Fig. 2～shown in Figure 6, above-mentioned reference column 2 tops are processed with three radially pin-and-hole 2-1,2-2,2-3, each radially pin-and-hole by three the part form, section 2-1-1 (φ 6 * 4), interlude 2-1-2 (φ 6.7 * 9), rear 2-1-3 (M8 * 11) respectively, the unit of above-mentioned size is mm, and anti-floating pin 3 fits into first section 2-1-1 from rear 2-1-3, the spring 4 of packing into subsequently, screw in interior angle at last and calm down screw 7 fixing springs 4 and pins 3, so just form the spring pin structure; Reference column 2 middle parts are processed with three annular groove 2-4,2-5,2-6, groove 2-4,2-5 are used to install square RunddichtringO 6, groove 2-6 is used to install O RunddichtringO 5, its role is to increase steadiness and the sealing that reference column 2 is connected with built-in fitting 1, bed die 10; Thread forms is processed in the reference column bottom, is used for bed die 10 and is connected with the screw threads for fastening of reference column 2.
As shown in Figure 7, the material that pin 3 adopts is No. 45 steel, and HB220-240 processes through heat treatment; The material that spring 4 adopts is that carbon spring steel wires I processes.Pin 3, spring 4, interior angle are calmed down screw 7 and are fitted into screw thread kissing that pin-and-hole 2-1 radially forms spring pin structure and built-in fitting 1 in order and merge and tighten.
Of the present invention installing and using: at first, all accessories are got ready, pin 3, spring 4, interior angle are calmed down screw 7 be installed in successively on the reference column 2, install the square RunddichtringO 6 and the O RunddichtringO 5 that are complementary.Then, reference column 2 is fastened on the bed die 10 by being threaded.At last, by the rotation mode that is screwed into built-in fitting 1 is tightened on the bed die 10.
