[0026] Reference below Figures 1 to 3 To describe the cable trench cover lifting device according to an embodiment of the present utility model.

[0027] According to the cable trench cover lifting device of the embodiment of the present utility model, it includes a vehicle body 3, a lifting frame 5, a limiting mechanism 10 and a lifting mechanism. The vehicle body 3 is provided with a slide rail 6 in the vertical direction; the lifting frame 5 is slidably arranged on the slide rail 6, and a take-up shaft 11 is rotatably arranged on the lifting frame 5, and a plurality of hooks 8 are provided on the take-up shaft 11; the limiting mechanism 10 is fixedly arranged on the lifting frame 5, and is connected to the take-up shaft 11 to limit the rotation of the take-up shaft 11; the lifting mechanism is fixedly arranged on the vehicle body 3, and is connected to the lifting frame 5, driving the lifting frame 5 to move up and down along the slide rail 6.

[0028] For example Figure 1 and Figure 2 As shown, the lifting frame 5 is fixedly connected to the vehicle body 3, and a take-up shaft 11 is provided on the lifting frame 5. The take-up shaft 11 can rotate, and two hooks 8 are provided on the take-up shaft 11. The hooks 8 are connected to the hooks 8 through wire ropes or cables, so that the take-up shaft 11 can be rotated to extend or retract the hooks 8, so that the hooks 8 can hang the cable trench cover.

[0029] The limiting mechanism 10 is fixedly arranged on the lifting frame 5 and is connected to the take-up shaft 11 to limit the rotation of the take-up shaft 11, so that the positions among the hook 8, the take-up shaft 11 and the cable trench cover can be relatively fixed.

[0030] The lifting mechanism is fixed to the vehicle body 3 and connected to the lifting frame 5. It drives the lifting frame 5 up and down along the slide rail 6, thereby lifting or lowering the cable trench cover, thereby facilitating the movement of the cable trench cover. The lifting mechanism adopts various methods, such as a screw rod 2, a piston cylinder, a rope and a motor.

[0031] According to the cable trench cover lifting device of the embodiment of the utility model, by such a configuration, at least the following beneficial effects can be achieved: the vehicle body 3 is moved onto the cable trench cover, the hook 8 on the take-up shaft 11 is hung on the cable trench cover by a wire rope or cable, so that the hook 8 hooks the hole on the cover, and then the take-up shaft 11 is restricted from rotating by the limiting mechanism 10, so that the position of the cable trench cover and the position of the take-up shaft 11 are relatively fixed, and the lifting frame 5 is lifted by the lifting mechanism to lift the cable trench cover for easy movement. By such a configuration, the hook 8 is prevented from hooking the take-up shaft 11 after the cable trench is modified, thereby firmly moving the cable trench cover.

[0032] In some specific embodiments of the present invention, a limiting tooth 12 is circumferentially arranged on the take-up shaft 11, and the limiting mechanism 10 includes a limiting rod 13 and a driving mechanism. The limiting rod 13 is arranged below the limiting tooth 12 and cooperates with the limiting tooth 12. The driving mechanism is connected to the limiting rod 13 and drives the limiting rod 13 to be inserted into the tooth groove of the limiting tooth 12.

[0033] For example Figure 3As shown, a limiting tooth 12 is circumferentially arranged on the take-up shaft 11, and a limiting rod 13 is arranged below the limiting tooth 12 and cooperates with the limiting tooth 12. The driving mechanism is connected to the limiting rod 13, and the limiting rod 13 is driven to be inserted into the tooth groove of the limiting tooth 12 to prevent the take-up shaft 11 from rotating, thereby facilitating the lifting mechanism to lift the lifting frame 5.

[0034] The driving mechanism can be adopted in various ways, such as screw rod 2, piston cylinder, rope and motor.

[0035] In some specific embodiments of the present invention, the limiting mechanism 10 includes a sleeve 16, a baffle 14 and a grip plate 17. The sleeve 16 is fixedly arranged, the baffle 14 is slidably arranged in the sleeve 16 and fixedly connected to the middle part of the limiting rod 13, and the grip plate 17 is arranged at the outer bottom of the sleeve 16 and fixedly connected to the bottom of the limiting rod 13. The driving mechanism drives the baffle 14 to slide in the sleeve 16 to drive the top of the limiting rod 13 to be inserted into the tooth groove of the limiting tooth 12.

[0036] For example Figure 3 As shown, a sleeve 16 is fixedly mounted on the lifting frame 5 and has a through hole formed therein. The baffle 14 and the limiting rod 13 are slidably mounted within the through hole in the sleeve 16. The through hole in the sleeve 16 is a hole of varying diameter, allowing the baffle 14 to slide within the sleeve 16 without slipping out. The limiting rod 13 has a smaller diameter than that of the baffle 14, allowing it to extend from the through hole in the sleeve 16.

[0037] The baffle 14 is connected to the drive mechanism and the limiting rod 13, so that the drive mechanism drives the baffle 14 to slide within the sleeve 16, thereby driving the limiting rod 13 to move within the sleeve 16. The through-hole size of the sleeve 16 is adapted to the size of the limiting rod 13, thereby controlling the movement trajectory of the limiting rod 13, so that the limiting rod 13 can be accurately inserted into the tooth groove of the limiting tooth 12, thereby limiting the rotation of the take-up shaft 11.

[0038] The gripping plate 17 is provided at the outer bottom of the sleeve 16 and is fixedly connected to the bottom of the limiting rod 13 , so that a person can pull the gripping plate 17 to move the limiting rod 13 .

[0039] When in use, move the vehicle body 3 to the top of the cable trench cover, pull the grip plate 17 to drive the limit rod 13 to disengage the limit tooth 12, thereby rotating the take-up shaft 11, lengthening the cable, and making the hook 8 hook the hole on the cable trench cover. Then release the grip plate 17, and the driving mechanism drives the limit rod 13 to insert into the limit tooth 12 to prevent the take-up shaft 11 from rotating. At this time, the lifting mechanism lifts the lifting frame 5, driving the lifting frame 5 to slowly slide upward on the surface of the slide rail 6, thereby lifting the cable trench cover.

[0040] In some specific embodiments of the present invention, the driving mechanism includes a spring 15 , which is disposed in a sleeve 16 . One end of the spring 15 is connected to the bottom of the baffle 14 , and the other end is connected to the inner bottom surface of the sleeve 16 .

[0041] For example Figure 3 As shown, the drive mechanism includes a spring 15, which is mounted within a sleeve 16. One end of the spring 15 is connected to the bottom of the baffle 14, and the other end is connected to the inner bottom surface of the sleeve 16. During use, the grip plate 17 is pulled to drive the limit rod 13 to compress the spring 15, thereby disengaging the limit tooth 12, thereby rotating the take-up spool 11 and extending the cable. Afterwards, the grip plate 17 is released, and the spring 15 drives the limit rod 13 to engage the limit tooth 12, preventing the take-up spool 11 from rotating. At this time, the lifting mechanism raises the lifting frame 5, causing it to slide slowly upward on the surface of the slide rail 6, thereby lifting the cable trench cover.

[0042] In some specific embodiments of the present invention, the top of the limiting rod 13 is conical.

[0043] For example Figure 3 As shown, the top of the limiting rod 13 is conical, and the conical limiting rod 13 makes it easier to insert the limiting rod 13 into the tooth groove of the limiting tooth 12.

[0044] In some specific embodiments of the present utility model, the lifting mechanism includes a turntable 1, a screw rod 2 and a nut 4, the nut 4 is fixedly connected to the lifting frame 5, one end of the screw rod 2 is threadedly connected to the nut 4, and the other end is fixedly connected to the turntable 1, and the screw rod 2 lifts the lifting frame 5 by rotating the turntable 1.

[0045] For example Figure 2 As shown, the lifting mechanism includes a turntable 1, a screw rod 2 and a nut 4. The nut 4 is fixedly connected to the lifting frame 5. One end of the screw rod 2 is threadedly connected to the nut 4, and the other end is fixedly connected to the turntable 1. By rotating the turntable 1, the screw rod 2 lifts the lifting frame 5. The threaded connection between the screw rod 2 and the nut 4 makes it convenient for the operator to rotate the screw rod 2 to raise or lower the lifting frame 5.

[0046] In some specific embodiments of the present invention, the turntable 1 is disposed on the top of the vehicle body 3 and connected to the screw rod 2 .

[0047] For example Figure 2 As shown, the turntable 1 is arranged on the top of the vehicle body 3 and connected to the screw rod 2, which makes it convenient for the operator to rotate the turntable 1.

[0048] In some specific embodiments of the present invention, a slider 7 is further included. The slider 7 is slidably disposed on the slide rail 6 , and the lifting frame 5 is fixedly connected to the slider 7 .

[0049] For example Figure 2As shown, it also includes a slider 7, which is slidably set on the slide rail 6. The lifting frame 5 is fixedly connected to the slider 7, so that the lifting frame 5 can be slidably connected to the slide rail 6, making it convenient for the lifting mechanism to lift the lifting frame 5.

[0050] In some specific embodiments of the present invention, two hooks 8 are spaced apart on the take-up reel 11 , and the two hooks 8 are fixedly connected to the take-up reel 11 via a steel wire rope.

[0051] For example Figure 2 As shown, two hooks 8 are arranged at intervals on the take-up shaft 11, and the two hooks 8 are fixedly connected to the take-up shaft 11 through steel wire ropes, which make the connection between the hooks 8 and the take-up shaft 11 more secure.
