[0002] During the maintenance and inspection of cables and their channels, a lot of work is often required to lift and carry cable trench covers. Cable trench covers are generally made of reinforced concrete, with a self-weight of 0.2 to 0.3 tons and a thickness of about 15 to 20 cm. There are multiple lifting holes on the cable trench covers for lifting and ventilation. The cable trench covers are generally lifted with a crowbar, and the cable trench covers are manually lifted and then carried away.

[0003] The presence of high-voltage live equipment above and around the substation cable trench limits the transportation space. The cable trench covers are not suitable for large machinery and can only be transported manually. Due to the large size and heavy weight of the substation cable trench covers, multiple people are required to carry them together. During the inspection and maintenance of the cable trench, the cover transportation operation is not only time-consuming and inefficient, but also poses a safety risk of accidental limb injuries. Summary of the invention

When in use, after the frame 1 is moved to the top of the cable trench cover 10 to be transported, the winding mechanism makes the support rod 9 swing to a vertical state, and the lifting mechanism is used to move the lifting beam 4 downward. When the support rod 9 is fully inserted into the lifting hole of the cable trench cover 10, the winding mechanism makes the support rod 9 swing in the opposite direction and become horizontal, so that the upper side of the support rod 9 contacts the lower side of the cable trench cover 10, and then the lifting mechanism moves the lifting beam 4 upward, and the cable trench cover 10 can be lifted by the winding mechanism and the support rod. When the cable trench cover 10 is lifted to a certain height, the frame 1 can be pushed to realize the transfer operation of the cable trench cover 10.

[0022] The above-mentioned cable trench cover handling device can be further optimized and / or improved according to actual needs: Embodiment 2: As an optimization of the above embodiment, as shown in the attached Figure 1 , 2 As shown in , 3 and 5, the winding mechanism includes a rope winding motor 11, a rope winding drum 12, a first connecting rope 13 and a second connecting rope 14. The rope winding motor 11 is fixedly installed on the upper middle part of the hoisting beam 4, and the rope winding drum 12 is fixedly installed on the outer front part of the output shaft of the rope winding motor 11; A left hinge seat 15 is fixedly installed on the lower right side of the left hoisting rod 8, and the left hinge seat 15 is hingedly installed with the upper right side of the left support rod 9. A left notch 16 opening downward is provided on the left side of the lower part of the left hoisting rod 8. A first connecting rope 13 whose first end is fixedly connected with the upper left side of the left support rod 9 is passed through the left hoisting rod 8, and the second end of the first connecting rope 13 is fixedly installed with the outer front side of the rope drum 12. A right hinged seat 17 is fixedly installed on the lower left side of the right lifting rod, and the right hinged seat 17 is hingedly installed with the upper left side of the right supporting rod. A right notch 18 opening downward is provided on the right side of the lower part of the right lifting rod. A second connecting rope 14 is passed through the right lifting rod, and the first end of the second connecting rope 14 is fixedly installed with the outer rear side of the rope drum 12.

[0023] According to the requirements, the rope winding motor 11 is an existing well-known reduction motor, the first connecting rope 13 and the second connecting rope 14 are both existing well-known steel wire ropes, in order to avoid the connecting rope and the outer side of the upper end of the lifting rod 8 from scratching each other, fixed pulleys are rotatably installed on the inner side of the upper part of the left lifting rod 8 and the inner side of the upper part of the right lifting rod, the second end of the first connecting rope 13 passes around the outer side of the right fixed pulley and is wrapped around the outer side of the front of the rope winding drum 12 for several turns, and then is fixedly connected to the outer side of the front of the rope winding drum 12, the second end of the second connecting rope 14 passes around the outer side of the left fixed pulley and is wrapped around the outer side of the rear of the rope winding drum 12 for several turns, and then is fixedly connected to the outer side of the rear of the rope winding drum 12, the second end of the first connecting rope and the second end of the second connecting rope 14 have the same winding direction on the outer side of the rope winding drum 12, and the left articulated seat 15 and the right articulated seat 17 have the same structure and are symmetrically arranged.

[0024] During use, the setting of the left notch 16 and the right notch 18 can reduce the cross-sectional area of ​​the lower end of the lifting rod 8, facilitate the insertion of the two support rods 9 into the lifting holes of the cable trench cover 10, and increase the swing angle of the two support rods 9. When the depth of the cable trench is small, the support rods 9 can also be retracted into the left notch 16 or the right notch 18, which is more convenient to use.

[0025] Embodiment 3: As an optimization of the above embodiment, as shown in the attached Figures 1 to 5 As shown, the left support rod 9 is in a straight line shape or a U-shape with an opening facing left.

[0026] According to the requirements, the right support rod is in a straight line or in a right-facing U-shaped shape, and the left support rod 9 and the right support rod have the same structure and are symmetrically arranged. During use, when the hanging hole of the cable trench cover 10 is large, the right support rod is in a U-shaped shape with an opening to the right, which can increase the contact area of ​​the support rod 9. When the hanging hole of the cable trench cover 10 is small, the right support rod is in a straight line shape, which is convenient for insertion into the hanging hole.

[0027] When the frame 1 moves to above the cable trench cover 10 to be transported, the rope winding motor 11 drives the rope winding drum 12 to rotate and then loosens the first connecting rope 13 and the second connecting rope 14, so that the right part of the right support rod swings downward, the left part of the left support rod 9 swings downward, and the left lifting rod 8 and the right lifting rod are inserted into the two lifting holes of the cable trench cover 10, finally allowing the left support rod 9 and the right support rod to pass through the lifting holes and be located below the cable trench cover 10.

[0028] Then the rope winding motor 11 drives the rope winding drum 12 to rotate and tighten the first connecting rope 13 and the second connecting rope 14. After the first connecting rope 13 pulls the right part of the right support rod, the right part of the right support rod becomes horizontal or tilted to the upper right. Similarly, after the second connecting rope 14 pulls the left part of the left support rod 9, the left part of the left support rod 9 becomes horizontal or tilted to the upper left. After the support rods 9 on both sides contact the lower side of the cable trench cover 10, the lifting beam 4 is lifted by the lifting mechanism, so that the left support rod 9 and the right support rod lift the cable trench cover 10 at the same time. When the cable trench cover 10 is lifted to a certain height, the frame 1 can be pushed to realize the transfer operation of the cable trench cover 10.

[0029] Embodiment 4: As an optimization of the above embodiment, as shown in the attached Figure 1 , 2 As shown in , 3 and 5 , the outer side of the upper part of the hanging rod 8 is inserted into the mounting through hole 7 at the corresponding position, and the outer side of the hanging rod 8 at the upper and lower sides of the corresponding support seat 3 is screwed with a fixing nut 19 .

[0030] During use, by setting the fixing nut 19, it is convenient to fix the lifting rod 8, which can constrain the first connecting rope 13 and the second connecting rope 14, and can also make the distance between the two lifting rods 8 larger than the distance between the lifting holes on the cable trench cover 10, so that the stability of the cable trench cover 10 during transportation can be improved after it is lifted.

[0031] Embodiment 5: As an optimization of the above embodiment, as shown in the attached Figure 1 , 2 As shown in Figures 3 and 5, the lifting mechanism includes a reduction motor 20, a lifting screw 21 and a guide rod 22. The reduction motor 20 is fixedly installed on the upper rear side of the support seat 3. A threaded hole that runs vertically through is provided in the center of the upper side of the lifting beam 4. The lifting screw 21 is screwed in the threaded hole. The lower end of the lifting screw 21 is transmission-connected to the upper end of the output shaft of the reduction motor 20. Guide holes that run vertically through are provided on the upper left and right sides of the lifting beam 4. A guide rod 22 whose lower end is fixedly installed at a corresponding position on the upper side of the support seat 3 is installed in each guide hole.

[0032] According to the requirements, the reduction motor 20 is a worm gear reduction motor with a self-locking effect, and the upper end of the output shaft of the reduction motor 20 is connected to the lower end of the lifting screw 21 through an existing well-known coupling transmission. During use, the setting of the guide rod 22, on the one hand, enables the lifting beam 4 to move up and down when the lifting screw 21 rotates, and on the other hand, it can also prevent the lifting beam 4 from shaking with the cable trench cover 10 during the transportation of the cable trench cover 10, which can improve the stability of the cable trench cover 10 during transportation.

[0033] Embodiment 6: As an optimization of the above embodiment, as shown in the attached Figure 1 , 2 As shown in Figures 3 and 5, the mounting through holes 7 are arranged in pairs, and each pair of mounting through holes 7 is centrally symmetrically arranged about the central axis of the threaded hole.

[0034] During use, through such an arrangement, after the cable trench cover 10 is lifted, the force on the support base 3 can be more centered, thereby improving the stability during transportation.

[0035] The above technical features respectively constitute various embodiments of the present invention, which have strong adaptability and implementation effect. Non-essential technical features can be added or reduced according to actual needs to meet the requirements of different situations.
