DETAILED DESCRIPTION OF THE EMBODIMENTS

[0023] In the description of the present utility model, it should also be noted that unless otherwise clearly specified and defined, if the terms "set", "installed", "connected", and "connected" appear, they should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium, and it can be the communication inside two components. For those of ordinary skill in the art, the specific meanings of the above terms in the present utility model can be understood according to specific circumstances.

[0024] The following will Figures 1 to 3 make a detailed description of the present utility model.

[0025] A tunnel catenary embedded channel inspection and correction device includes a column 1. A fixing bolt 101 is arranged at the bottom of the column 1. A placing rack 2 is arranged at the top of the column 1. A calibration plate 201 is connected to the middle of the top of the placing rack 2. A resisting block 202 is arranged at the bottom middle of the placing rack 2. A connecting block 2011 is arranged at the bottom of the calibration plate 201. The connecting block 2011 is connected to the middle of the top of the resisting block 202. A lifting assembly is arranged at the top of the column 1. The lifting assembly is connected to both ends of the calibration plate 201.

[0026] First, place the embedded parts of the construction channel of the tunnel on the placing rack 2 supported by the column 1, and then place the embedded parts in a fitting manner through the calibration plate 201. At the same time, the arc bending radian of the calibration plate 201 is the radian standard of the embedded parts. When the embedded parts are placed on the calibration plate 201 in a fitting manner, if the embedded parts do not meet the standard of the circular ring bending, gaps will be generated between some parts and the calibration plate 201, and the generation of the gaps is the position where the embedded parts do not meet the radian requirements. In this way, the stability of the embedded parts can be observed according to the calibration of the calibration plate 201 to facilitate correction.

[0027] Further, the abutting block 202 is a semi-circular convex block at the central position of the middle of the top groove of the placement rack 2. The lifting assembly includes a connecting rod 102, a fitting groove 103, a rotating disk 104 and a synchronous gear 105. The connecting rod 102 is arranged at the tops of the outermost ends of several columns 1 at the bottom of the placement rack 2. The fitting groove 103 is arranged at the top of the column 1. The rotating disk 104 is connected to the top of the column 1. The synchronous gear 105 is arranged at the top of the rotating disk 104. The connecting rod 102 passes through the bottom of the placement rack 2 and is connected to both ends of the calibration plate 201. The fitting groove 103 is a groove arranged at the top of the column 1 to cooperate with the connecting rod 102. The rotating disk 104 further includes a limiting ring 1041. The limiting ring 1041 is a ring protrusion arranged at the bottom of the rotating disk 104 and is limit-rotationally connected to the top of the column 1. The inner wall of the middle part of the rotating disk 104 is thread-matched with the side wall of the connecting rod 102. The calibration plate 201 includes a hinge shaft 203. The hinge shaft 203 is a circular shaft where the bottom of the calibration plate 201 near both ends is hinged to the connecting rod 102. The calibration plate 201 is made of shape memory metal.

[0028] Meanwhile, when it is necessary to calibrate embedded parts with different bending radian, the rotating disk 104 can be controlled to rotate, so that it will drive the connecting rod 102 to move up and down along the fitting groove 103 through the thread, so that it will apply force to pull both ends of the calibration plate 201 through the connection with the hinge shaft 203 at the top, so that both ends of the calibration plate 201 will tilt downward. At the same time, the central position of the calibration plate 201 will be limit-connected to the abutting block 202 through the connecting block 2011, so that the central position of the calibration plate 201 will not change, but the inclination angles of both sides will change, so that the radian of the calibration plate 201 can be adjusted to a certain extent to adapt to embedded parts with different radian standards.

[0029] Further, the synchronous gear 105 further includes a synchronous belt 1051. The synchronous belt 1051 is a rack arranged on the side wall of the synchronous gear 105, and the synchronous gear 105 passes through several columns 1 and meshes with the synchronous gear 105 at the other end.

[0030] Finally, the rotating disks 104 on the outermost columns 1 at both ends will cooperate with the synchronous belt 1051 through the synchronous gears 105 at the top, so that when one rotating disk 104 rotates, it will drive the other rotating disk 104 to rotate synchronously, so as to make the calibration plate 201 tilt simultaneously, so as to change the radian of the calibration plate 201.

[0031] The following is the specific implementation process of the present utility model. First, place the embedded parts of the construction slot of the tunnel on the placement rack 2 supported by the column 1, and then place the embedded parts in a fitting manner through the calibration plate 201. At the same time, the arc bending radian of the calibration plate 201 is the radian standard of the embedded parts. When the embedded parts are placed on the calibration plate 201 in a fitting manner, if the embedded parts do not meet the standard of the circular ring bending, there will be a gap between some parts and the calibration plate 201, and the position where the gap appears is the position where the embedded parts do not meet the radian requirements. In this way, the stability of the embedded parts can be observed according to the calibration of the calibration plate 201 to facilitate correction. At the same time, when calibrating the embedded parts with different bending radians, the rotation of the rotating disk 104 can be controlled to rotate, so that it will drive the connecting rod 102 to move up and down along the fitting groove 103 through the thread. In this way, through the connection of the top with the hinge shaft 203, force is applied to pull both ends of the calibration plate 201, so that both ends of the calibration plate 201 will tilt downward. At the same time, the central position of the calibration plate 201 is connected to the abutting block 202 through the connecting block 2011, so that the central position of the calibration plate 201 will not change, but the inclination angles of both sides will change, so that the radian of the calibration plate 201 can be adjusted to a certain extent to adapt to the embedded parts with different radian standards. Finally, the rotating disks 104 on the two ends of the column 1 will cooperate with the synchronous gears 105 on the top and the synchronous belt 1051, so that when one rotating disk 104 rotates, it will drive the other rotating disk 104 to rotate synchronously, so that the calibration plate 201 can tilt simultaneously, so as to change the radian of the calibration plate 201.

[0032] The above is only the preferred embodiment of the present utility model and is not used to limit the present utility model. For those skilled in the art, the present utility model can have various changes and modifications. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present utility model shall be included in the protection scope of the present utility model.
