[0034] The following will describe in detail the specific embodiments of the present utility model with reference to the drawings.

[0035] As Figure 1 shown, a mobile frame for transporting the cable trough cover plate of the ditch in the high-speed rail tunnel includes:

[0036] Two brackets 1; the two brackets 1 are arranged at the same horizontal height and are parallel to each other;

[0037] A pulling rope 4; both ends of a pulling rope 4 are respectively connected to the closer ends of the two brackets 1;

[0038] Two groups of rollers 2; one group of rollers 2 is installed on the outer side wall of each bracket 1; one group of rollers 2 includes two rollers 2; the rollers 2 are vertically arranged, and the two groups of rollers 2 are respectively rollably placed above both sides of the ditch;

[0039] A telescopic adjusting device 5 for adjusting the distance between the two brackets 1; the telescopic adjusting device 5 is installed between the two brackets 1;

[0040] Two groups of side wheels 3; One group of side wheels 3 is installed at the lower end of each bracket 1; One group of side wheels 3 includes two side wheels 3; The side wheels 3 are horizontally arranged, and the two groups of side wheels 3 are respectively rollably placed on the two side walls of the water channel.

[0041] As Figure 1 and 2 shown, the telescopic adjusting device 5 includes a threaded barrel 51, a screw 52, a handle 54, and a connecting rod. The first end of the threaded barrel 51 is rotatably installed in a bracket 1. The inner wall of the threaded barrel 51 is provided with internal threads, and the threaded barrel 51 is in threaded cooperation with the screw 52. One end of the screw 52 is fixedly connected to another bracket. A storage groove 53 is formed on the arc surface of the threaded barrel 51. The first end of the handle 54 is connected to the middle of the connecting rod. The handle 54 is perpendicular to the connecting rod. The two ends of the connecting rod are rotatably connected to the two side walls of the storage groove 53. The friction force between the connecting rod and the side wall of the storage groove 53 needs to ensure that when the storage groove 53 faces downward, the connecting rod does not fall downward; The length of the handle 54 is less than the length of the storage groove 53. When not in use, the handle 54 is placed in the storage groove 53. A rubber sleeve 55 is sleeved on the second end of the handle 54, and anti-slip patterns are provided on the outer wall of the rubber sleeve 55. By setting the handle, the effect of facilitating the staff to rotate the threaded barrel is achieved. When the handle is not needed, the handle is moved into the storage groove, achieving the effect of storing the handle and avoiding the handle from affecting the staff to place the cover plate. By setting the rubber sleeve, the friction force between the staff's hand and the handle is increased, facilitating the staff to move the handle and bringing convenience to the staff.

[0042] As Figure 1 and 3 shown, the moving frame further includes two guiding components. The two guiding components are arranged in parallel. The guiding component includes a guiding rod 57 and a guiding tube 56. The guiding rod 57 is slidably placed in the guiding tube 56 in a guiding manner.

Both the guiding rod 57 and the guiding tube 56 are perpendicular to the bracket 1. A circular plate 58 is installed at the second end of the guiding rod 57. A fixing ring 59 is installed inside the second end of the guiding tube 56. The inner diameter of the fixing ring 59 is smaller than the diameter of the circular plate 58. The circular plate 58 is slidably placed in the guiding tube 56 in a guiding manner. By the movement of the guiding rod in the guiding tube, the effect of restricting the moving direction of the two brackets is achieved, avoiding the two brackets from rotating relative to each other. Through the mutual cooperation of the fixing ring and the circular plate, the effect of restricting the maximum displacement between the guiding rod and the guiding tube is achieved, avoiding the separation of the guiding tube and the guiding rod.

[0043] As Figure 1 and 4As shown in the figure, the moving frame further includes an auxiliary device 6. The auxiliary device 6 includes a backing plate 61, a winding rod 62, a rectangular plate 63, a plug plate 64, and an elastic cord 66.

A through hole is vertically provided near the edge of the rectangular plate 63. A jack corresponding to the vertical position of the through hole is provided on the backing plate 61. The top width of the plug plate 64 is greater than the width of the through hole. The sizes of the through hole and the jack are the same. The plug plate 64 is inserted into the through hole and the jack from top to bottom. One end of the elastic cord 66 is connected to the top of the rectangular plate 63, and the other end of the elastic cord 66 is connected to the top of the plug plate 64. When the drawstring needs to be used, move the drawstring and wind it around the winding rod, achieving the effect of storing the drawstring. Through the auxiliary device, the effect of facilitating the staff to store the drawstring is achieved, bringing convenience to the staff. After winding the drawstring, move the plug plate on the rectangular plate. The plug plate passes through the rectangular plate and is inserted into the jack of the backing plate, achieving the effect of limiting the drawstring. By setting the elastic cord, the effect of limiting the maximum displacement of the plug plate is achieved, preventing the plug plate from falling off when not in use.

[0044] Working principle: When it is necessary to adjust the distance between the two brackets 1, first rotate the handle 54 by 90°, making the handle perpendicular to the threaded cylinder. The end of the handle extends out of the storage groove 53. Drive the threaded cylinder 51 to rotate through the handle 54. The threaded cylinder 51 does not move. The screw 52 in the threaded cylinder 51 drives one bracket to move. The total length of the threaded cylinder 51 and the screw 52 changes, thereby adjusting the distance between the two brackets 1. After the two brackets 1 are adjusted to the appropriate positions, rotate the handle 54 back into the storage groove 53. When carrying the cover plate, first place the cover plate on the two brackets 1, pull the drawstring 4, and the drawstring 4 drives the brackets 1 and the cover plate to move. The side wheels 3 at the bottom of the brackets 1 rotate against the inner wall of the water channel, preventing the brackets 1 from detaching from the water channel. Through the adjusting device 5, the effect of facilitating the staff to adjust the distance between the two brackets 1 is achieved, facilitating the moving frame composed of the brackets 1 to adapt to cable trough water channels of different widths, and improving the practicability of the moving frame.

[0045] The above are only the preferred embodiments of the present invention. It should be noted that for those of ordinary skill in the art, without departing from the technical principle of the present invention, several improvements and refinements can still be made, and these improvements and refinements should also be regarded as the protection scope of the present invention.
