DETAILED DESCRIPTION

[0020] In order to further explain the technical means and systems adopted by the present invention to achieve the predetermined purpose, the specific implementation methods, structural features and conversion systems of the present invention are described in detail below in conjunction with the accompanying drawings and embodiments.

[0021] like Figure 1 and Figure 2 As shown, the present invention relates to a conversion system of a one-machine multi-point traction turnout, which is characterized in that: a plurality of groups of installation foundations 3 are fixed at intervals on one side of a sleeper near a traction point of a turnout track, and a plurality of groups of traction mechanism points are fixed at intervals along the rail through the installation foundations 3 and the turnout, and the traction mechanism points include: a first external locking mechanism 1, a second external locking mechanism 12, a third external locking mechanism 14, a detection rod 2, an installation foundation 3, a switch machine 4, a first installation rod 5, a bending rod 6, a first T-shaped turning arm 7, a first turning seat 8, a first connecting rod 9, a second installation rod 10, a second T-shaped turning 11, a second connecting rod 13, a third installation rod 15, and a third T-shaped turning arm 16; the first external locking mechanism 1, the second external locking mechanism 12, and the third external locking mechanism 14 are respectively fixed at the positions of the first traction point, the second traction point, and the third traction point,

[0022] A switch machine 4 is arranged at the position of the first traction point. The switch machine 4 is installed vertically to the turnout. The power output rod of the switch machine 4 is connected to pull the first external locking mechanism 1. At the same time, the power output rod of the switch machine 4 is connected to the first mounting pull rod 5 and the bent pull rod 6. The other end of the bent pull rod 6 is connected to a vertical arm pin of the first T-shaped turning arm 7. The first T-shaped turning arm 7 is fixed on the first turning seat 8. The turning arm can rotate around the axis of the turning seat. The movable rail of the first traction point is connected to one end of the detection rod 2, and the other end of the detection rod 2 is connected to the switch machine detection rod.

[0023] Under the push and pull action of the bend pull rod 6, the first T-shaped turn arm 7 will rotate around the rotation axis of the first turn seat 8, output the force and displacement output by the switch machine 4 from the horizontal arm of the T-shaped turn arm, and convert the rotational motion into the movement of the first connecting rod 9 along the axis parallel to the length direction of the turnout.

[0024] like Figure 3As shown, the second external locking mechanism 12 is fixed at the position of the second traction point of the movable rail, one end of the first connecting rod 9 is connected to the first T-shaped crank arm 7, and the other end is connected to the horizontal arm of the second T-shaped crank arm 11, so as to transmit the rotation of the first T-shaped crank arm 7 to the vertical arm of the second T-shaped crank arm 11; the second installation pull rod 10 is connected to the vertical arm of the second T-shaped crank arm 11, and the second installation pull rod 10 is also connected to the second external locking mechanism 12, and the first connecting rod 9 transmits power and displacement to the second external locking mechanism 12 through the second T-shaped crank arm 11.

[0025] like Figure 4 As shown, the third external locking mechanism 14 is fixed at the position of the third traction point, one end of the second connecting rod 13 is connected to the horizontal arm of the second T-shaped crutch arm 11, and the other end is connected to the horizontal arm of the third T-shaped crutch arm 16, so that the rotation of the second T-shaped crutch arm 11 is transmitted to the vertical arm of the third T-shaped crutch arm 16; the third installation pull rod 15 is connected to the vertical arm of the third T-shaped crutch arm 16, and the third installation pull rod 15 is also connected to the third external locking mechanism 14, and the second connecting rod 13 transmits power and displacement to the third external locking mechanism 14 through the third T-shaped crutch arm 16.

[0026] refer to Figure 1 , Figure 2 , Figure 3 , Figure 4 The first external locking mechanism 1, the second external locking mechanism 12, and the third external locking mechanism 14 are respectively connected to the movable rails of the first traction point, the second traction point, and the third traction point.

[0027] During the conversion process, the position of the first traction point sets the force and displacement output by the switch machine 4. Through the rotation of the connecting rod and the crank arm, the force and displacement of the first traction point position parallel to the turnout are converted into the force and displacement perpendicular to the turnout, and the second external locking mechanism 12 and the third external locking mechanism 14 are pushed and pulled to convert and lock the second and third traction points of the movable rail. A close fit checker 17 is fixed on one side of the second external locking mechanism 11 to detect the close fit of the second traction point of the point rail. If more traction points are required, the force and displacement are transmitted backward in the same way.

[0028] The lengths of the second installation rod 10 and the third installation rod 15 can be adjusted according to the travel of different turnout traction points to meet the needs of traction point conversion and locking.

[0029] The second traction point and the third traction point are located on the same side of the switch machine 4, so that the structure can be compact when transmitting force and displacement.

[0030] The crankshaft is provided with a lubrication mechanism, and the traction point can adopt an external locking mechanism or an internal locking mechanism. Then the first external locking mechanism 1, the second external locking mechanism 12 and the third external locking mechanism 14 can all adopt the connecting rod of the internal locking mechanism.

[0031] In the design of the present invention: 1) the mounting base 3 has a compact structure, the mounting base 3 of the first T-shaped turning arm 7 is arranged together with the mounting base 3 of the switch machine 4, and the mounting base 3 of the second T-shaped turning arm 11 and the third T-shaped turning arm 16 adopts a part of the mounting base 3 of the switch machine 4, and the parts have high versatility.

[0032] 2) The first connecting rod 9 and the second connecting rod 13 are both in two groups, which are symmetrically installed on the parallel arms of the T-shaped crank arm, so that the force is evenly applied during the transmission conversion.

[0033] 3) The second installation rod 10 and the third installation rod 15 are rod structures with adjustable lengths, which can be adjusted according to the requirements of different travels and locking amounts of the traction point.

[0034] The above contents are further detailed descriptions of the present invention in combination with specific preferred embodiments, and it cannot be determined that the specific implementation of the present invention is limited to these descriptions. For ordinary technicians in the technical field to which the present invention belongs, several simple deductions or substitutions can be made without departing from the concept of the present invention, which should be regarded as falling within the protection scope of the present invention.
