[0026] Reference Figures 1 to 6 The embodiments of the intelligent tunnel construction trolley of this utility model are further described below.

[0027] The intelligent tunnel construction trolley includes a trolley frame 1, a support plate 2, and casters 3. The trolley frame 1 is fixedly connected to the support plate 2. It also includes: There are four fixed columns 4, which are fixedly installed on the support plate 2; they provide support for the first motor 8 and limit the position of the screw 9. Reference Figure 1 , Figure 2 , Figure 5 and Figure 6In a preferred embodiment, the lifting mechanism comprises four components, each mounted on a fixed column 4, used to drive the casters 3 to move up and down. The lifting mechanism includes: There are four first motors 8, and the four first motors 8 are fixedly mounted on the fixed column 4; There are four screws 9, which are rotatably mounted on the first motor 8. One end of each screw 9 is fixedly connected to the output end of the first motor 8. Four rectangular threaded sleeves 10 are provided, and the four rectangular threaded sleeves 10 are set on the screw 9 and threadedly connected to the screw 9. The lifting assembly comprises four components, each mounted on a rectangular threaded sleeve 10. The lifting assembly includes: Eight L-shaped fixing plates 11 are provided. The eight L-shaped fixing plates 11 are fixedly mounted on the rectangular threaded sleeve 10 and are slidably connected to the fixing column 4. There are four lifting plates 12, which are fixedly mounted on the L-shaped fixed plate 11 and rotatably connected to the casters 3.

[0028] The fixed column 4 has eight lifting slots 13, which are used to limit the lifting trajectory of the L-shaped fixed plate 11.

[0029] There are eight limit posts 5, which are installed on the lifting mechanism. During operation, the first motor 8 is started, which drives the screw 9, which is fixedly connected to its output end, to rotate. The screw 9 drives the rectangular threaded sleeve 10 to move up and down. The rectangular threaded sleeve 10 drives the L-shaped fixing plate 11 to move up and down along the lifting groove 13. The L-shaped fixing plate 11 drives the lifting plate 12 to move up and down. The lifting plate 12 is used to drive the caster 3 to move up and down, thereby adjusting the height of the support plate 2 so that the device is in a horizontal state and prevents overturning caused by the center of gravity shift. The rectangular threaded sleeve 10 is also used to drive the limiting post 5 to move up and down, thereby driving the locking mechanism to move up and down. Reference Figure 6 In a preferred embodiment, the locking mechanism comprises eight locking mechanisms, which are disposed on the limiting post 5 to fix the limiting post 5; the locking mechanism includes: Eight springs 14 are provided, and the eight springs 14 are set on the limiting post 5, with one end of the spring 14 fixedly connected to the limiting post 5; Eight inclined plates 15 are provided, and the eight inclined plates 15 are set on the spring 14 and fixedly connected to the other end of the spring 14. The support column 16 is fixedly mounted on the inclined plate 15 and is slidably connected to the limiting column 5.

[0030] Multiple inclined slots 17 are provided on the fixed column 4 to limit the position of the inclined plate 15.

[0031] During operation, the rectangular threaded sleeve 10 drives the limiting post 5 to move up and down. The limiting post 5 drives the spring 14 and the support post 16 to move up and down. The support post 16 and the spring 14 drive the inclined plate 15 to move up and down. When the inclined plate 15 moves to the inclined slot 17, the spring 14 releases its elastic potential energy to drive the inclined plate 15 to move, so that the inclined plate 15 is inserted into the inclined slot 17, thereby fixing the fixing post 4 and playing an auxiliary fixing role for the rectangular threaded sleeve 10, reducing the burden on the screw 9.

[0032] Reference Figures 1 to 4 In a preferred embodiment, four moving mechanisms are provided, and the four moving mechanisms are disposed on the support plate 2; the moving mechanisms include: There are four second motors 18, and the four second motors 18 are fixedly mounted on the support plate 2; There are four bidirectional lead screws 19, which are rotatably mounted on the support plate 2. One end of the bidirectional lead screw 19 is fixedly connected to the output end of the second motor 18. Eight nut sleeves 20 are provided, and the eight nut sleeves 20 are set on the bidirectional lead screw 19 and threadedly connected to the bidirectional lead screw 19. There are eight connecting posts 21, which are fixedly mounted on the nut sleeve 20. There are eight movable columns 22, which are fixedly mounted on the connecting column 21.

[0033] The support column 16 has eight movable slots 23, which are used to limit the movement position of the connecting column 21.

[0034] During operation, the second motor 18 is started, which drives the bidirectional screw 9, which is fixedly connected to its output end, to rotate. The bidirectional screw 9 drives the two nut sleeves 20 to move towards each other. The nut sleeves 20 drive the two connecting columns 21 to move towards each other. The connecting columns 21 drive the two moving columns 22 to move. The moving columns 22 move into the inclined slot 17, push the inclined plate 15 out of the inclined slot 17, and compress the spring 14, so that the lifting mechanism can operate normally to adjust the height of the universal wheel 3. There are four electronic levels 6, which are fixedly installed on the support plate 2 to detect the tilt angle of the support plate 2. The controller 7 is fixedly mounted on the support plate 2.

[0035] During operation, the electronic level 6 detects the tilt angle of the support plate 2 in real time and transmits the information to the controller 7. The controller 7 starts the second motor 18 to insert the moving column 22 into the inclined slot 17. Then, the first motor 8 is started to adjust the height of the caster wheel 3. When the appropriate height is reached, the second motor 18 is started to move the moving column 22 out of the inclined slot 17. The spring 14 releases its elasticity and drives the inclined plate 15 to be inserted into the inclined slot 17, thereby further fixing the rectangular threaded sleeve 10.

[0036] Working principle: When driving on a sloped surface, the electronic level 6 detects the tilt angle of the support plate 2 in real time and transmits the information to the controller 7. The controller 7 starts the second motor 18, which drives the bidirectional screw 9 to rotate. The bidirectional screw 9 drives the two nut sleeves 20 to move towards each other. The nut sleeves 20 drive the two connecting columns 21 to move towards each other. The connecting columns 21 drive the two moving columns 22 to move. The moving columns 22 move into the inclined slot 17, pushing the inclined plate 15 out of the inclined slot 17 and compressing the spring 14. At this time, the controller 7 starts the first motor 8, which drives the screw 9 to rotate. The screw 9 drives the rectangular threaded sleeve 10 to move up and down. The rectangular threaded sleeve 10 drives the L-shaped fixing plate 11 to move up and down along the lifting groove 13. The L-shaped fixing plate 11 drives the lifting plate... The lifting plate 12 moves up and down, driving the caster wheel 3 to move up and down, thereby adjusting the height of the support plate 2 and keeping the device in a horizontal position to prevent overturning caused by the shift of the center of gravity. The rectangular threaded sleeve 10 drives the L-shaped fixing plate 11 to move while also driving the limiting post 5 to move up and down. The limiting post 5 drives the spring 14 and the support post 16 to move up and down. The support post 16 and the spring 14 drive the inclined plate 15 to move up and down. When the inclined plate 15 moves to the inclined slot 17, the second motor 18 is started to drive the moving post 22 to move out of the inclined slot 17. At this time, the spring 14 releases its elastic potential energy to drive the inclined plate 15 to move, so that the inclined plate 15 is inserted into the inclined slot 17, thereby fixing the fixing post 4 and playing an auxiliary fixing role for the rectangular threaded sleeve 10, reducing the burden on the screw 9.

[0037] The above description of the embodiments enables those skilled in the art to make or use the present invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention is not to be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
