[0023] The utility model provides Figure 1-2 A new type of cable trench cover lifting device shown in the figure includes a bidirectional screw rod 1 and two movable base plates 2. The upper surfaces of the two movable base plates 2 are fixedly connected with fixing frames 3, and are respectively connected with mounting plates 4 through corresponding fixing frames 3. The bidirectional screw rod 1 is rotatably set between the two mounting plates 4. The rod wall of the bidirectional screw rod 1 is symmetrically threaded with two sliders 5. The bottoms of the two sliders 5 are respectively provided with connecting mechanisms, and are respectively connected with winding wheels 6 through corresponding connecting mechanisms. A traction rope 7 is fixedly wound inside each winding wheel 6, and the other end of each traction rope 7 is fixedly connected with a hook 8. A driving mechanism is set between the two mounting plates 4, and the two winding wheels 6 are both connected with the driving mechanism. By using the two movable base plates 2, the position of the entire device can be easily moved and adjusted, so that the staff can adjust the position of the entire device according to the actual environment of the construction site.

[0024] like Figure 1-2 As shown, the connecting mechanism includes a connecting block 9 and two sleeves 10. The connecting block 9 is fixedly arranged at the bottom of the corresponding slider 5 and two L-shaped rods 11 are symmetrically fixedly arranged on the side wall. The other ends of the two L-shaped rods 11 are fixedly connected with annular plates 12. The two annular plates 12 are symmetrically rotatably sleeved on the two end walls of the sleeve 10. The sleeve 10 is fixedly penetrated into the inside of the corresponding winding wheel 6. By utilizing the set connecting mechanism, the corresponding winding wheel 6 can be driven to move during the movement of the slider 5, thereby realizing the position adjustment of the winding wheel 6.
