A kind of operating mechanism that is used for the track switch lane change
Technical field
The utility model relates to a kind of operating mechanism that is used for the track switch lane change.
Background technology
The application of track is very extensive, mostly uses the mode of track switch as lane change when track needs lane change.Generally, simple turnout comprises trapped orbit, cross track and movable rail, by adjusting the free end of movable rail, make a side of a free-ended side and stock rail closely recline the gap that the opposite side of free-ended opposite side and trapped orbit has the electric locomotive wheel to pass through.Adopted electric locomotive as transportation means on present most ore deposit, pass through the simple turnout lane change during electric locomotive lane change, the mode that when the free end of mobile movable rail, adopts pedal or hand to dial, but the mode that adopts pedal or hand to dial is extremely inconvenient, and the free end of movable rail and trapped orbit are closed easily bad, easily cause the overturning of electric locomotive, and there is hidden danger in staff's secure context.
The utility model content
The purpose of this utility model provides a kind of operating mechanism that is used for the track switch lane change easy, easy to use.
For achieving the above object, the utility model by the following technical solutions: a kind of operating mechanism that is used for the track switch lane change, comprise pull bar, an end of pull bar is connected with pull bar, pull bar is arranged on the crossbeam of the support that fixes on the ground.
Described pull bar is two sections, wherein offer through hole on one section, be equipped with the connecting pin that two ends are all protruded this section surface and can be slided along through hole in the through hole, connecting pin is connected with another section pull bar by a U-joint, captives joint with the two ends of connecting pin respectively in the two ends of U-joint U-shaped.
Described through hole is a strip shape.
The pull bar of described crossbeam top is provided with clump weight.
The upper end of described pull bar is provided with handle.
It is simple in structure that the utility model is used for the operating mechanism of track switch lane change, this operating mechanism is positioned at outside the track switch during use, rotate along crossbeam by lever operated pull bar, thereby the free end of pull bar horizontal anomalous movement control movable rail is moved, thereby realize the lane change of track switch; Be specially: by U-joint connecting pin is slided thereby the rotation of pull bar drives right pull bar horizontal anomalous movement along the strip shape through hole, the control free end moved when connecting pin slid into the two ends of strip shape through hole, realized the lane change of track switch; The operation pull bar rotates up and down along crossbeam, rely on lever principle to make the pull bar activity, dial more laborsaving than direct pedal or hand, it is more accurate that the free end of movable rail is put in place, the overturning of avoiding the closed bad grade of free end to cause, and the workman has with a certain distance from track switch in when operation, can guarantee operator's personal safety.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
The specific embodiment
As shown in Figure 1, pull bar is made up of left pull bar 10 and right pull bar 9, wherein left pull bar 10 1 ends offer strip shape through hole 12, be equipped with the connecting pin 13 that two ends are all protruded left pull bar 10 surfaces and can be slided along strip shape through hole 12 in the strip shape through hole 12, right pull bar 9 is connected with connecting pin 13 by U-joint 11, captive joint with the two ends of connecting pin 13 respectively in the two ends of the U-shaped of U-joint 11, the end that right pull bar 9 does not connect connecting pin 13 is connected with pull bar 4, pull bar 4 is arranged on the crossbeam 6 of the support 5 that fixes on the ground, the pull bar 4 of crossbeam 6 tops is provided with clump weight 7, and the upper end of pull bar 4 is provided with handle 3.
An end that during use left pull bar 10 is not connected connecting pin 13 extends and is fixed in the below of the free end 8 of movable rail 2 through trapped orbit 1 below.Rotate along crossbeam 6 by handle 3 operation pull bars 4, thereby the rotation of pull bar 4 drives right pull bar 9 horizontal anomalous movements makes connecting pin 13 slide along strip shape through hole 12, the free end 8 of control movable rail 2 moved when connecting pin 13 slid into the two ends of strip shape through hole 12, realized the lane change of track switch.
