[0002] The close contact checker is a device for checking the close contact and repulsion between the traction points of the turnout. The close contact checker is a device for checking the close contact and repulsion between the traction points of the turnout.

[0020] The following is combined with Figure 1-Figure 3 This application is described in further detail.

[0021] The present application embodiment discloses a turnout close contact inspection device. Figure 1-Figure 3 A turnout close fit inspection device comprises a close fit inspection device shell 1 and a shell cover 2, a pair of fixing holes 9 are opened on both sides of the upper end of the close fit inspection device shell 1; a pair of fixing plates 7 are fixed at the bottom of the shell cover 2; and a locking mechanism is also included, the locking mechanism comprises a movably installed insertion rod 4, the insertion rod 4 is adapted to the fixing hole 9, and the locking mechanism is used to connect and fix the close fit inspection device shell 1 and the shell cover 2. When the shell cover 2 is installed on the close fit inspection device shell 1, at this time, the insertion rod 4 corresponds to the fixing hole 9 horizontally.

[0022] In this embodiment, if Figure 1 and Figure 2 As shown, an embedding edge 5 is fixed on the top of the close contact inspection device housing 1, and the housing cover 2 is sleeved on the embedding edge 5.

[0023] In this embodiment, if Figure 1 and Figure 2 As shown, a U-shaped hole 10 is opened on one side of the close contact inspection device housing 1.

[0024] In this embodiment, if Figure 2 As shown, the notch of the fixing hole 9 is provided with a chamfer 6, which facilitates the insertion rod 4 to be inserted into the fixing hole 9 more smoothly, thus facilitating installation.

[0025] In this embodiment, if Figure 2 and Figure 3 As shown, a bidirectional screw rod 13 is rotatably installed between the two fixed plates 7, and a screw-on long plate 8 is screwed on the left and right threads of the bidirectional screw rod 13. The two screw-on long plates 8 can be close to or away from each other, and the insertion rod 4 is fixed on the screw-on long plate 8. A manual knob 3 is fixed at one end of the bidirectional screw rod 13, and the connecting rod of the manual knob 3 and the bidirectional screw rod 13 is embedded in the U-shaped hole 10. When installing, first install the shell cover 2 on the close-fitting inspector shell 1, and turn the manual knob 3 clockwise to make the two screw-on long plates 8 move away from each other, thereby gradually inserting the insertion rod 4. The installation and fixing can be completed in the fixing hole 9. The operation is simple, convenient and fast. By setting the manual knob 3, the insertion rod 4, the fixing plate 7, the screw-on long plate 8, the fixing hole 9, the guide rod 11 and the two-way screw 13, after the shell cover 2 is installed on the close-fitting inspector shell 1, it is only necessary to screw a manual knob 3. The two-way screw 13 drives the two screw-on long plates 8 to move, so that the insertion rod 4 can be inserted into the fixing holes 9 respectively, thereby realizing the rapid installation and fixing of the close-fitting inspector shell, avoiding the traditional steps of screwing multiple screws, improving convenience and practicality.

[0026] In this embodiment, if Figure 2 and Figure 3 As shown, a pair of guide rods 11 are also fixed between the two fixed plates 7. The two guide rods 11 both penetrate the spin-on long plate 8 and are slidably connected to the spin-on long plate 8. The guide rods 11 can prevent the spin-on long plate 8 from rotating with the bidirectional screw rod 13, have a limiting function, and enable the spin-on long plate 8 to move smoothly.

[0027] In this embodiment, if Figure 2 and Figure 3 As shown, a positioning ring 12 is fixed on the insertion rod 4, and the positioning ring 12 can be connected to the close contact inspection device housing 1. When the insertion rod 4 is inserted into the fixing hole 9, the positioning ring 12 fits with the close contact inspection device housing 1 and has a limiting function.

[0028] The implementation principle of a turnout close fit inspection device in the embodiment of the present application is as follows: during installation, first install the shell cover 2 on the close fit inspection device housing 1, and turn the manual knob 3 clockwise to make the two screw-on long plates 8 move away from each other, so that the insertion rod 4 is gradually inserted into the fixing holes 9 respectively, and the installation and fixing are completed. The operation is simple, convenient and fast. By setting the manual knob 3, the insertion rod 4, the fixing plate 7, the screw-on long plate 8, the fixing hole 9, the guide rod 11 and the two-way screw rod 13, after the shell cover 2 is installed on the close fit inspection device housing 1, only one manual knob 3 needs to be turned, and the two screw-on long plates 8 are driven to move by the two-way screw rod 13, so that the insertion rod 4 can be inserted into the fixing holes 9 respectively, thereby realizing the rapid installation and fixation of the close fit inspection device housing, avoiding the traditional steps of screwing multiple screws, improving convenience and practicality.
