Description
Technical field
The utility model relates to a kind of arc length measuring and calculating device of arc rail, belongs to technical field of measuring equipment.
Background technology
Arc rail is in curved in tracks position, arc rail is easily caused to occur that side weares and teares when vehicle turning or lane change, therefore arc rail needs to safeguard or change after operation a period of time, and in prior art, lack a kind of measuring and calculating device of arc rail, central angle corresponding to arc rail is also difficult to measuring and calculating, makes troubles to the production and processing of replacing arc rail.
Utility model content
The purpose of this utility model is to overcome deficiency of the prior art, provides a kind of arc length measuring and calculating device of arc rail, solves the technical problem that arc rail arc length in prior art is difficult to calculate.
For solving the problems of the technologies described above, the technical solution adopted in the present invention is: the arc length measuring and calculating device of arc rail, comprise generating laser, the first laser pickoff and the second laser pickoff, described generating laser is located at one end of rail by the first installing rack, and the other end of rail is located at by described first laser pickoff by the second installing rack;
Described first installing rack is also provided with the first guide peg, and described generating laser to be horizontally slipped with the first guide peg by the first guide holder and is connected; Described second installing rack is provided with the second guide peg, and the second laser pickoff to be horizontally slipped with the second guide peg by the second guide holder and is connected; Described first guide peg and the second guide peg parallel setting, and the first guide peg, the second guide peg line all and between the first installing rack and the second installing rack is perpendicular.
One is had at least to be provided with distance scale in described first guide peg, the second guide peg.
Described first guide peg runs through the first guide holder, and described second guide peg runs through the second guide holder, and the first guide peg, the second guide peg are leading screw, and the first guide holder, the second guide holder are provided with the internal thread matched with the external screw thread of leading screw.
One end of described first guide peg and one end of the second guide peg are respectively arranged with rotation hand wheel.
Described first installing rack, the second installing rack include respective mount pad, respectively for the manipulator that connects rail and the support bar be connected between mount pad and manipulator.
Described manipulator is Pneumatic manipulator.
During use, on the starting point that first installing rack, the second installing rack are installed on rail respectively and terminal, generating laser sends laser signal to the first laser pickoff, for measuring the chord length connecting rail starting point and rail terminal, synchronizing moving generating laser and the second laser pickoff, when the second laser pickoff can receive laser signal, stop mobile, read the distance of generating laser movement, i.e. action, calculated the arc length of rail by chord length and action.Compared with prior art, the beneficial effect that the utility model reaches: structure is simple, with low cost, can realize the measuring and calculating of arc rail arc length fast, the degree of accuracy is high, operating efficiency is high.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
In figure: 1, generating laser; 2, the first laser pickoff; 3, the second laser pickoff; 4, the first guide peg; 5, the second guide peg; 6, rotation hand wheel; 7, rail.
Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is further described.Following examples only for clearly the technical solution of the utility model being described, and can not limit protection domain of the present utility model with this.
As shown in Figure 1, the arc length measuring and calculating device of arc rail, comprise generating laser 1, first laser pickoff 2 and the second laser pickoff 3, generating laser 1 is located at one end of rail 7 by the first installing rack, and the other end of rail 7 is located at by the first laser pickoff 2 by the second installing rack.
First installing rack is also provided with the first guide peg 4, generating laser 1 to be horizontally slipped with the first guide peg 4 by the first guide holder and is connected.Second installing rack is provided with the second guide peg 5, second laser pickoff 3 and is horizontally slipped with the second guide peg 5 by the second guide holder and be connected.First guide peg 4 and the second guide peg 5 parallel setting, and the line of the first guide peg 4, second guide peg 5 all and between the first installing rack and the second installing rack is perpendicular.
Have at least one to be provided with distance scale in first guide peg 4, second guide peg 5, directly can be read the distance of generating laser 1 and the second laser pickoff 3 translation by distance scale.
First guide peg 4 runs through the first guide holder, and the second guide peg 5 runs through the second guide holder, and the first guide peg 4, second guide peg 5 is leading screw, and the first guide holder, the second guide holder are provided with the internal thread matched with the external screw thread of leading screw.One end of first guide peg 4 and one end of the second guide peg 5 are respectively arranged with rotation hand wheel 6.By rotation hand wheel 6 rotational lead screw, be positioned at generating laser 1 on leading screw and the second laser pickoff 3 to side translation.
First installing rack, the second installing rack include respective mount pad, respectively for the manipulator that connects rail 7 and the support bar be connected between mount pad and manipulator.Preferably, manipulator is Pneumatic manipulator.
During use, on the starting point that first installing rack, the second installing rack are installed on rail 7 respectively and terminal, generating laser 1 sends laser signal to the first laser pickoff 2, for measuring the chord length connecting rail 7 starting point and rail 7 terminal, synchronizing moving generating laser 1 and the second laser pickoff 3, when the second laser pickoff 3 can receive laser signal, stop mobile, read the distance of generating laser 1 movement, i.e. action, calculated the arc length of rail 7 by chord length and action, circular is as follows:
If the distance between generating laser 1 and the first laser pickoff 2 is l, when second laser pickoff 3 can receive the photosignal of generating laser 1 transmitting, the distance that translation occurs generating laser 1 is h, be converted into the right chord length l of known circular arc and action h thus, ask the mathematical problem of arc length, as calculated, the central angle θ that arc rail 7 is right, the design formulas of arc length L is as follows:
The above is only preferred embodiment of the present utility model; should be understood that; for those skilled in the art; under the prerequisite not departing from the utility model know-why; can also make some improvement and distortion, these improve and distortion also should be considered as protection domain of the present utility model.
