Background Art

[0002] The turnout switching equipment is used to change the direction of track opening. When the turnout is switched and pulled to the specified position, the electrical contacts of the automatic switch must immediately give a corresponding opening or closing action, opening and closing the corresponding electrical contacts, thereby opening or connecting the corresponding circuit, and giving an indication of the turnout position status.

[0003] The key to accurately indicating the position status of the turnout is whether the inspection column can reliably fall into the gap of the indicating rod. At the same time, if the falling depth is not enough, it will also affect the driving depth of the moving contact, resulting in poor circuit contact and unstable indicating signals when the turnout is switched.

[0004] For a long time, the inspection column needs to be lubricated with grease to ensure its smooth movement. Dust can easily stick to the grease and enter the hole where the inspection column moves up and down, causing jamming. In addition, under low temperature conditions, the viscosity of the grease increases, which further aggravates the effect of jamming. Summary of the invention

DETAILED DESCRIPTION

[0014] In order to further explain the technical means and methods adopted by the present invention to achieve the predetermined purpose, the specific implementation methods, structural features and methods of the present invention are described in detail below in conjunction with the accompanying drawings and embodiments.

[0015] like Figure 1 and Figure 2 As shown, it relates to a self-lubricating and oil-free automatic opener and closer for checking post holes of a linear motion switch machine, which is characterized in that it includes a contact seat 2, a static contact 1, four contact covers 14, left and right turning shafts 3 and a spline shaft 16, wherein the contact seat 2 is a left and right symmetrical structure, the left and right static contacts 1 are installed at both ends of the left and right contact seats 2, the left contact seat has two contact covers 14, the right contact seat has two contact covers 14, the two contact covers 14 of the left and right contact seats are distributed at both ends thereof, the left turning shaft 3 is in the middle of the left contact seat 2, and the right turning shaft 3 is in the middle of the right contact seat 2; left and right brackets 12 are respectively installed on the left and right turning shafts 3, a group of moving contacts 13 and a connecting shaft 10 are fixed on each of the left and right brackets 12, an inspection column 11 is hung under the connecting shaft 10, the inspection column 11 passes through the hole of the contact seat 2, and a bushing 15 is embedded in the hole of the contact seat 2.

[0016] The spline shaft 16 is fastened to the left and right brackets 12 via splines, and the rotation of the spline shaft 16 drives the connecting shaft 10, the left and right brackets 12 and the movable contact 13 to rotate together.

[0017] The left and right turning shafts 3 are on the outside of the contact seat 2, and are respectively provided with a connecting plate 4, an adjustment frame 5, a quick-acting claw 7, an adjusting bolt 6 and a tension spring 8 through the left and right turning shafts 3; both ends of the tension spring 8 are fixed by a tension spring joint 9, and the left and right parts are connected through the adjustment frame 5.

[0018] The self-lubricating and oil-free automatic opener and closer for the inspection post hole of the linear motion switch machine of the utility model has a self-lubricating characteristic that significantly reduces the dependence on regular oiling and maintenance in practical applications. The inlaid bushing 15 inlaid in the hole of the inspection post 11 effectively reduces the accumulation of dust and grease in the hole, thereby avoiding the occurrence of jamming. At the same time, the material of the inlaid bushing 15 is specially selected and has excellent lubrication performance, so that the inspection post can remain smooth during movement without the need to add additional lubricating oil.

[0019] In addition, the symmetrical structural design of the utility model makes the installation and maintenance process easier. The bilaterally symmetrical contact seat 2 and component layout make it easy to align and fix during the installation process, thereby improving work efficiency. At the same time, this design also facilitates the replacement and debugging of components during maintenance.

[0020] The combination of the adjustment frame 5, the quick-acting claw 7 and the adjusting bolt 6 makes the utility model have excellent adjustment performance. By adjusting the adjusting bolt 6, the position of the quick-acting claw 7 can be easily adjusted, thereby realizing accurate control of the movement stroke of the inspection column 11. When the quick-acting claw 7 is lifted, such as when the right quick-acting claw 7 is lifted by the rotating mechanism, the quick-acting claw 7 lifts the adjusting frame 5 through the adjusting bolt 6, and the adjusting frame 5 drives the right turning shaft 3, the right bracket 12, and the connecting shaft 10 to rotate around the spline shaft of the turning shaft 3 in turn, thereby lifting the connecting shaft 10, and the connecting shaft 10 drives the inspection column 11 to move upward. At this time, the moving contact 13 moves to the right and is connected with the static contact 1, that is, the power supply and the indicating circuit are turned on; such as when the right quick-acting claw 7 is pulled down by the rotating mechanism, the moving contact 13 moves to the left and is disconnected from the static contact 1. Under the action of the tension spring 8, the whole frame 5 drives the right turning shaft 3, the right bracket 12, and the connecting shaft 10 to rotate left around the spline shaft of the turning shaft 3 in turn, and the inspection column 11 moves downward. The left and right actions are mirror images, and are similar in sequence.

[0021] The tension spring 8 connects the left and right parts through the adjustment frame 5, ensuring the stability and reliability of the switch structure. The elastic force of the tension spring 8 can be adjusted as needed to adapt to different working environments and load conditions. This design makes the utility model more adaptable and durable.

[0022] In summary, the utility model of the self-lubricating and oil-free automatic opener and closeer for the inspection post hole of the linear motion switch machine effectively solves the long-standing problem of having to oil the inspection post, causing obstruction and affecting the indication signal by adopting a self-lubricating bushing, a symmetrical structural design and a flexible adjustment function. At the same time, its simple installation and maintenance process as well as its excellent adaptability and durability make the utility model have a wide range of application prospects in practical applications.
