Abstract
The utility model relates to a radius rule for measuring curves. In order to solve the problems that the existing manual railway curve measurement mode has the disadvantages of time waste, big error and inconvenience, the utility model provides the radius rule for measuring curves which is characterized in that the radius rule for measuring curves is mainly composed of a T-shaped ruler and a straight-line displacement measuring device, wherein the T-shaped ruler is divided into a transverse rod and a vertical rod; the straight-line displacement measuring device is mainly composed of a measuring rod, a transmission system and a reading device; the straight-line displacement measuring device is fixed to the joint of the transverse rod and the vertical rod of the T-shaped ruler or arranged on the vertical rod. The radius rule for measuring curves of the utility model can be conveniently read out curve radius values from a dial plate. Compared with the method of manual measuring tape measurement, the radius rule for measuring curves has the advantages of simple operation, precise data, time saving, labor saving and convenience.
Description
Technical field
The utility model relates to a kind of measurement instrument, particularly a kind of measurement instrument of measuring sweep.
Background technology
Newly-built or safeguard in the railway process and often need measure to the sweep of railway.Three grades of railways particularly, sweep is little, variation is many, when train travels on curved rail length, because the guide effect of rail, the stressing conditions of track than the straight line complexity many, and curve track is because road speed differs, and therefore, the actual fixedly superelevation that is provided with can not adapt fully with it, add all complex conditions that the characteristics of curve track own cause, cause the deformation of how much states of curve track to be accelerated, this will cause train to rock on curve track, be unfavorable for traffic safety.For guaranteeing traffic safety, prolong the serviceable life of rail, need in time curve track to be checked and revised, the physical dimension that surpasses allowable value of track is corrected come, to guarantee the correct and stable of how much states of curve track.More than work and all must grasp the sweep size of track.The method that existing railroader measures the rail curve radius is the air line distance that measures point-to-point transmission on the rail with chi earlier, measures the length of curve of point-to-point transmission then with tape measure, at last by manually calculating the sweep of this lengths of rail.Because often the measurement to the sweep of a lengths of rail needs repeated measurement, makes that so staff's workload is very big, special spended time records data and also has bigger error, seems very inconvenient.
Summary of the invention
In order to solve the problem that existing hand dipping rail curve mode is time-consuming, error is big, inconvenient, the utility model proposes a kind of survey sweep chi, it is characterized in that: described survey sweep chi mainly is made of T shape chi and straight-line displacement measuring appliance; Described T shape chi is divided into cross bar and montant; Described straight-line displacement measuring appliance mainly is made up of measuring staff, kinematic train and reading device; The straight-line displacement measuring appliance is fixed on the node place of T shape chi cross bar and montant or is installed on the montant.Use survey sweep chi of the present utility model, can read the sweep value from dial plate very easily, it is simpler with the method operation of tape measuring to compare craft, and data are more accurate, and are time saving and energy saving, make things convenient for a lot.
Description of drawings
Fig. 1 is dial gauge of the present utility model or clock gauge example structure sketch.
Fig. 2 is a rack pinion example structure sketch of the present utility model.
Embodiment
The straight-line displacement measuring appliance mainly is made up of measuring staff, kinematic train and reading device.Figure 1 shows that an embodiment of the present utility model.The straight-line displacement measuring appliance of present embodiment adopts existing dial gauge, according to actual needs, if require more high precision can also select for use clock gauge to substitute dial gauge.As Fig. 1, a pair of contact 32 on the cross bar 30 of dial gauge 1, measuring staff 2, T shape chi 3, curved rail length 4, T shape chi, the montant 31 of T shape chi and the T shape chi.T shape chi 3 is as the holder of dial gauge 1.Dial gauge 1 is fixed on the node place of cross bar 30 and montant 31, and the measuring staff 2 on the dial gauge 1 passes from the centre of cross bar 30, if the measuring staff of dial gauge falls short of, can also increase before measuring staff and connects a thimble.Because dial gauge is a kind of fine measuring instrument that straight-line displacement is carried out reading, what show on its dial plate is straight-line displacement, if show the sweep value on the dial plate, the numerical value that indicates on its dial plate will be done corresponding change.Existing dial gauge or clock gauge that mainly contain the dial plate reading with the two major types electronic digital display indication, this two class all is suitable for the utility model.
Fig. 2 is another embodiment of the present utility model.The straight-line displacement measuring appliance of present embodiment still mainly is made up of measuring staff, kinematic train and reading device.This routine straight-line displacement measuring appliance is used the measuring principle of dial gauge, utilizes rack pinion or lever and gear wheel transmission, reaches the purpose that the straight-line displacement of measuring staff is become the angular displacement of pointer, and it is compared among Fig. 1 dial gauge sensitivity and will hang down, but has cost advantage.As shown in Figure 2, the straight-line displacement measuring appliance in the present embodiment is made up of dial plate 10a, gear 11a, driving cog 12a, spring 13a and measuring staff 2a, also is shown with curved rail length 4a, T shape chi 3a, cross bar 30a, montant 31a, spring pedestal 33a and contact 32a among the figure.Measuring staff 2a one end stretches out from the node of T shape chi cross bar and montant, is with spring 13a on the other end, and spring 13a is connected with spring pedestal 33a on the montant.On measuring staff, between spring and the T shape chi node, driving cog 12a is arranged, on montant 31a, be fixed with corresponding transmission gear 11a, transmission gear connects with pointer on the dial plate 10a.The dial plate of the hand-held spring balance that dial plate can be drawn materials commonly used is marked with corresponding dial plate reading and gets final product.The straight line that the measuring staff that measured size causes is small moves, and amplifies through gear drive, becomes the rotation of pointer on index dial.
The utility model also can be used for the mechanical fields such as maintenance such as diesel engine cylinder circularity except the orbital curve that is applied to railway is measured.
Claims (3)
1. survey the sweep chi for one kind, it is characterized in that: described survey sweep chi mainly is made of T shape chi and straight-line displacement measuring appliance; Described T shape chi is divided into cross bar and montant; Described straight-line displacement measuring appliance mainly is made up of measuring staff, kinematic train and reading device; The straight-line displacement measuring appliance is fixed on the node place of T shape chi cross bar and montant or is installed on the montant.
