[0024] The first support frame 1 is rotatably connected to the top of one end of the second support frame 3 with a pull rod 2, so that the device can be pushed and moved by hand through the pull rod 2, and first displacement grooves 10 are opened inside the top of both sides of the first support frame 1 and located near the end of the second support frame 3, and second displacement grooves 11 are opened inside the top of both sides of the second support frame 3 and located near the end of the first support frame 1, so that when the top of the second support frame 3 is parallel to the top of the first support frame 1, the first displacement groove 10 and the second displacement groove 11 are connected;

[0025] The two sides at both ends of the bottom of the first support frame 1 and the bottom of both sides of the second support frame 3 away from the first support frame 1 are bolted with a connecting frame 6, and the internal rotation of the connecting frame 6 is connected to the displacement wheel 5, and a displacement driving rotating motor 7 is fixed to one side of the connecting frame 6. The output end of the displacement driving rotating motor 7 is connected to the displacement wheel 5, so that the operation of the displacement driving rotating motor 7 drives the displacement wheel 5 to rotate, so that the device can be electrically controlled to move. A fixing frame 8 is provided on the top of the first support frame 1, and support plates 9 are fixed on both sides of the fixing frame 8. Both ends of the bottom of the support plate 9 are rotatably connected to a translation adjustment wheel 12, and the translation adjustment wheel 12 and the first displacement slot 10, and the translation adjustment wheel 12 and the second displacement slot 11 are all slidably connected, so that the rotation of the translation adjustment wheel 12 can drive the fixing frame 8 and the support plate 9 to reciprocate on the top of the first support frame 1 and the second support frame 3, so that the translation adjustment wheel 12 can move inside the first displacement slot 10 and the second displacement slot 11;

[0026] The connecting frame 6 and the displacement wheel 5 form a group. In this embodiment, three groups of connecting frames 6 and displacement wheels 5 are provided, and a total of six displacement drive rotary motors 7 are provided on the three groups of connecting frames 6 and displacement wheels 5. In actual use, the number of connecting frames 6, displacement wheels 5 and displacement drive rotary motors 7 can be reasonably set according to the overall length and weight of the device. For example, a displacement drive rotary motor 7 is only provided on the middle group of connecting frames 6 and displacement wheels 5 among the three groups of connecting frames 6 and displacement wheels 5. As long as the smooth movement of the device can be met, it can be sufficient. It should be noted that if multiple groups of displacement wheels 5 are driven by displacement drive rotary motors 7, it can be considered to set multiple displacement drive rotary motors 7 for synchronous operation.

[0027] Guide rods 13 are fixed to both ends of the top of the support plate 9. The outer sides of the two guide rods 13 on the same side are slidably connected with a lifting plate 14. A push rod motor 15 is fixed to the top of the support plate 9. The push rod of the push rod motor 15 is fixed to the lifting plate 14, so that the operation of the push rod motor 15 drives the lifting plate 14 to move up and down. A synchronous housing 16 is fixed to the inner side of the lifting plate 14, so that the lifting plates 14 on both sides are lifted and lowered at the same time, driving a synchronous housing 16 to move up and down;

[0028] In other embodiments, the push rod motor 15 may also be a hydraulic cylinder or a pneumatic cylinder.

[0029] Positioning assemblies are installed on the outer sides of both sides of the synchronous housing 16, so that the cover plate is driven to move by the two positioning assemblies. The positioning assembly includes a first displacement plate 19, a second displacement plate 20 and a third displacement plate 21. The first displacement plate 19 is slidably connected to the synchronous housing 16. The second displacement plates 20 are fixed on both sides of the first displacement plate 19. The third displacement plate 21 is fixed between the bottoms of the two second displacement plates 20.

An adjustment drive motor 17 is fixed inside the synchronous housing 16, and an adjustment threaded rod 18 is connected to the output end of the adjustment drive motor 17. The adjustment threaded rod 18 is threadedly connected to the first displacement plate 19, so that the first displacement plate 19 is driven to move by the rotation of the adjustment threaded rod 18;

[0030] In this embodiment, two adjustment drive motors 17 are provided inside the synchronization housing 16. The operation of the two adjustment drive motors 17 drives the corresponding connected adjustment threaded rods 18 to rotate. At the same time, the two first displacement plates 19 are driven to move in the opposite direction by the opposite rotation of the threads of the two adjustment threaded rods 18 or the opposite rotation of the output shafts of the two adjustment drive motors 17.

[0031] The use process of the portable cable trench cover opening and closing device provided by the present invention is as follows: when in use, the device is moved to the top of the cable trench cover, and then the translation adjustment wheel 12 is rotated by pushing, so that the translation adjustment wheel 12 is moved to the cover position that needs to be opened and closed inside the first displacement slot 10 and the second displacement slot 11, and then the adjustment drive motor 17 is driven to rotate the adjustment threaded rod 18, and the rotation of the adjustment threaded rod 18 drives the first displacement plate 19 to move, so that the two third displacement plates 21 are moved in the opposite direction to a position beyond the size of the cover, and then the push rod motor 15 is driven to drive the lifting plate 14 to descend, so that the lifting plate 14 is lowered. The descent of the plate 14 drives the third displacement plate 21 to descend through the synchronous housing 16, so that the bottom of the third displacement plate 21 is located at the bottom of the cover. At this time, the reverse rotation of the adjusting drive motor 17 is driven to rotate the adjusting threaded rod 18, so that the two third displacement plates 21 move closer and clamp the cover. Then, the lifting plate 14 and the synchronous housing 16 are driven to rise through the operation of the push rod motor 15, so that the clamped cover rises, and then the cover is moved to other positions through the rotation of the translation adjustment wheel 12, thereby realizing opening. When closing, the rotation of the translation adjustment wheel 12 drives the cover to move to the appropriate position, and the cover is driven to descend through the operation of the push rod motor 15 through the third displacement plate 21 to realize closing.
