[0018] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0019] See also Figure 1-Figure 4 , the utility model provides a technical solution:

[0020] A mobile formwork frame for ditch cable trough construction, comprising a frame body 1, a template system main body 2 is installed on the left and right sides of the frame body 1, two power-assisted walking devices 3 are symmetrically rotated and installed below the front end of the frame body 1, and a follower wheel 4 is symmetrically rotated and installed below the rear end of the frame body 1, two fixed blocks 11 and a double-output shaft drive motor 12 are fixedly installed on the upper surface of the frame body 1, and the output ends of the double-output shaft drive motor 12 are fixedly installed with screws 13, and the outer ends of the screws 13 are respectively rotatably connected with the corresponding fixed blocks 11, and two U-shaped frames 5 are symmetrically slidably installed on the upper surface of the frame body 1, and two positioning wheels 51 are symmetrically rotated and installed on the outer ends of the U-shaped frames 5, and the U-shaped frames 5 are screwed with the corresponding screws 13;

[0021] Before use, the frame 1 is pushed into the tunnel from the middle position of the tunnel entrance, and then the shaft drive motor 12 is powered on and started. After starting, the shaft drive motor 12 can drive the U-shaped frame 5 to move outward with the help of the bolts 13 at both ends, so that the positioning wheels 51 on the outside of the U-shaped frame 5 fit on the inner wall of the tunnel, and then the formwork system main body 2 is used to build the ditch cable trough. After construction, the power-assisted walking device 3 is used to assist the mobile frame 1 to change the construction position. During the movement of the frame 1, the frame 1 is limited by the two U-shaped frames 5 and the positioning wheels 51 on the top, so that the frame 1 can be kept in the middle of the tunnel for precise movement to avoid deviation. After moving to the designated position, the construction can be continued. After the construction is completed, the shaft drive motor 12 is rotated in the opposite direction, and the screw 13 can be used to drive the U-shaped frame 5 to move inward and reset, thereby releasing the positioning of the frame 1.

[0022] It should be noted that if Figure 4 As shown, the inner side end of the U-shaped frame 5 is symmetrically provided with an I-shaped slide groove 52, such as Figure 2 As shown, the upper surface of the frame body 1 is symmetrically fixed with an I-shaped slide rail 14, and the I-shaped slide rail 14 is slidably connected with the I-shaped slide groove 52 to achieve the sliding installation of the U-shaped frame 5 on the upper surface of the frame body 1;

[0023] like Figure 3 As shown, the power-assisted walking device 3 includes a rotating shaft 31 and a reduction motor 33. The rotating shaft 31 passes through and is rotatably installed at the bottom of the front end of the frame 1. The reduction motor 33 is fixedly installed on the inner wall of the frame 1. A driving wheel 32 is fixedly installed on the outer end of the rotating shaft 31. The outer surface of the output shaft of the reduction motor 33 and the outer surface of the rotating shaft 31 are both provided with a bevel gear 34. The two bevel gears 34 are meshingly connected. The reduction motor 33 can utilize the linkage effect of the two bevel gears 34 to drive the rotating shaft 31 and the driving wheel 32 to rotate, thereby achieving the purpose of power-assisted walking of the frame. It should be noted that the two reduction motors 33 on both sides need to be electrically connected to an external synchronous controller, and the external synchronous controller is used to synchronously control the two reduction motors 33, so as to ensure the stability of the frame 1 when walking.

[0024] Due to the large amount of dust and impurities at the construction site, in order to prevent the impurities from entering the meshing point of the two bevel gears 34 and affecting the transmission effect, Figure 2 and Figure 1 Two protective shells 6 are symmetrically fixedly installed on the front end of the inner wall of the frame body 1. The inner end of the rotating shaft 31 and the bevel gear 34 are both located in the corresponding protective shells 6. The protective shells 6 can be used to cover the meshing part of the two bevel gears 34 to avoid affecting the transmission effect.

[0025] Finally, in order to ensure the overall strength of the mold frame, the U-shaped frame 5 needs to be set to be made of aluminum alloy. The U-shaped frame 5 made of aluminum alloy is not easy to deform and is more stable during use.
