[0002] A large number of control cables and power cables in substations need to be laid and fixed on cable racks in cable trenches. In order to prevent rain and sunlight from damaging the cables, shortening or damaging the cable life, or even creating unsafe factors, the cable trenches need to be covered with covers. And with the continuous advancement of power grid construction, the number of substation cable laying projects is increasing. Cable trench covers have been widely used in power grid projects and are an indispensable infrastructure in substation cable trench construction.

Detailed implementation manners

[0021] In order to more clearly illustrate the technical solutions of the embodiments of the present utility model, the following will briefly introduce the drawings required to be used in the embodiments. Obviously, the drawings in the following description are some embodiments of the present utility model. For those of ordinary skill in the art, without creative efforts, other drawings can also be obtained based on these drawings.

[0022] Please refer to Figures 1-4 , an embodiment of the present utility model provides a cable trench cover lifting device, including: a support mechanism 10, a connection mechanism 20, a lever 30, and a lifting mechanism 40; the lower end of the support mechanism 10 is used to support on the ground, and the upper end is rotatably connected to the lower end of the connection mechanism 20, the lever 30 is slidably connected to the connection mechanism 20, the lifting mechanism 40 is arranged on both sides of the connection mechanism 20 and is slidably connected to the connection mechanism 20; the lever 30 and the lifting mechanism 40 are arranged in parallel and can both slide in the same direction.

[0023] In this embodiment, the support mechanism 10 can support the device on the ground and serve as a support point for lifting the cable trench cover plate; the lever 30 is slidably connected to the connecting mechanism 20, and the lifting mechanisms 40 are arranged on both sides of the connecting mechanism 20 and are slidably connected to the connecting mechanism 20. Thus, when lifting the cable trench cover plate, the support mechanism 10 is arranged at a suitable position, the lever 30 is pushed so that the working end of the lever 30 slides into the gap of the cover plate, and then the lever 30 is pressed down to lift the cover plate. Then, the lifting mechanisms 40 on both sides are slid to be located under the lifted cover plate, so that the cover plate can be lifted. The operation of this device is convenient, time-saving and labor-saving. Even a single worker can lift the cover plate, which can greatly improve the efficiency of cable maintenance and repair work. Moreover, the use of this device avoids the close contact between the worker and the cover plate, thereby reducing the risk of injury to the worker.

[0024] For the support mechanism 10, it may specifically include: a triangular support frame 11, rollers 12 and a first fixing component 13; the upper end of the triangular support frame 11 is rotatably connected to the lower end of the connecting mechanism 20, and the lower end of the triangular support frame 11 is provided with rollers 12; the first fixing component 13 is rotatably connected to the triangular support frame 11 and is used to fix the support mechanism 10 on the ground. In this way, the rollers 12 are arranged on the device, and the movement of the device can be realized. Thus, when going to the next working point for lifting operations or carrying the cover plate, a great deal of manpower and time can be saved, which is beneficial to improving work efficiency.

[0025] For the first fixing component 13, it can fix the device at the working point, so as to ensure that the device does not move during the process of lifting the cable trench cover plate, which may affect the lifting operation of the cover plate. Specifically, the first fixing component 13 may include a first sleeve 131 and a fixing rod 132. One end of the first sleeve 131 is rotatably connected to the triangular support frame 11, and a plurality of first fixing holes 133 are provided on the first sleeve 131; the fixing rod 132 is of an L-shaped structure, and a plurality of second fixing holes 134 are provided on the long side of the fixing rod 132, and the long side of the fixing rod 132 is arranged inside the first sleeve 131 and is connected to the first sleeve 131 through bolts, the first fixing holes 133 and the second fixing holes 134; the short side of the fixing rod 132 is provided as a tip.

[0026] In this embodiment, the length of the fixing rod 132 extending out of the first sleeve 131 can be adjusted. Thus, in actual operations, according to the actual operation scenario, a suitable length can be adjusted for fixing the device. For example, the length of the fixing rod 132 extending out is adjusted so that the tip of the fixing rod 132 can be stuck in the brick joints near the cover plate or inserted into the ground.

[0027] It should be noted that the short side and the long side of the fixing rod 132 can be vertically arranged or arranged at a certain angle.

[0028] In one embodiment, the upper end of the triangular support frame 11 is not only rotatably connected to the second sleeve 21, but can also slide along the outer surface of the second sleeve 21 at the same time. In this way, when lifting the cover plate by the lever 30, the connection point of the triangular support frame 11 can be slid towards the end close to the cover plate, so as to increase the lever arm on the working side of the staff and achieve the purpose of saving effort.

[0029] For the connecting mechanism 20, it may specifically include a second sleeve 21, a second fixing component 22 and a third sleeve 23; the lower end of the second sleeve 21 is rotatably connected to the triangular support frame 11, the lever 30 is arranged inside the second sleeve 21 and can slide along the second sleeve 21; there are four second fixing components 22, two are arranged on each side of the second sleeve 21, and the second fixing components 22 on both sides are symmetrically arranged with respect to the second sleeve 21; the lower ends of the two second fixing components 22 on each side are lapped and fixed to a third sleeve 23.

[0030] Wherein, the second fixing component 22 may include a cross bar 221, a vertical bar 222 and a mounting ring 223; one end of the cross bar 221 is fixed on the side surface of the second sleeve 21, and the other end is fixedly connected to the mounting ring 223; the vertical bar 222 is sleeved in the mounting ring 223, and a plurality of mounting holes are arranged on the vertical bar 222, and mounting holes are also arranged on the mounting ring 223 for adjustably mounting the vertical bar 222 on the mounting ring 223 through bolts.

[0031] In this embodiment, the lever 30 can slide in the second sleeve 21, that is, the lever 30 can be extended or retracted. When lifting the cover plate, the lever 30 can extend into the gap of the cover plate to lift the cover plate. And the second fixing component 22 includes a vertical bar 222, a cross bar 221 and a mounting ring 223, and the vertical bar 222 and the cross bar 221 are adjustably mounted, so that the height difference between the lifting mechanism 40 and the lever 30 can be adjusted, so as to adapt to the lifting operation of cover plates of different thicknesses. For example, when the cover plate is relatively thick, the lifting mechanism 40 can be lowered by adjusting the mounting position of the vertical bar 222, so that the height difference between the lever 30 and the lifting mechanism 40 becomes larger, so as to realize the lifting operation of a cover plate with a larger thickness.

[0032] For the lifting mechanism 40, it may include two groups, which are respectively rotatably sleeved inside two third sleeves 23 on both sides of the second sleeve 21 and can slide along the third sleeve 23. Specifically, the lifting mechanism 40 may include: a rotating handle 41, a carrying rod 42 and a clamping block 43; one end of the carrying rod 42 is fixedly connected to the rotating handle 41, the other end is fixedly connected to the clamping block 43, and the clamping block 43 is perpendicular to the carrying rod 42; the carrying rod 42 is sleeved inside the third sleeve 23.

[0033] In this embodiment, the lifting mechanism 40 is respectively arranged inside the third sleeves 23 on both sides and can slide along the third sleeves 23. The lifting mechanism 40 specifically includes a rotating handle 41, a carrying rod 42, and a clamping block 43. Thus, when one side of the cover plate is lifted by the lever 30, the carrying rods 42 on both sides are pushed to slide by the rotating handle 41, so that the carrying rods 42 extend under the cover plate, and the clamping block 43 is located on the other side of the cover plate. Then, the carrying rod 42 is rotated by the rotating handle 41, so that the clamping block 43 rotates and clamps on the other side of the cover plate. Further pressing down the lever 30 can completely lift the cover plate off the ground and realize the transportation of the cover plate. In this way, not only is the cover plate lifted by the carrying rods 42 on both sides, but also the sliding of the cover plate is prevented by the clamping block 43, ensuring the success of the lifting while avoiding potential safety hazards caused by the falling of the cover plate.

[0034] In addition, in order to ensure that the carrying rod 42 does not slide randomly during the lifting process, that is, does not extend or retract randomly. In one embodiment, it is considered that an L-shaped limiting groove 231 is opened on each third sleeve 23, and a number of threaded holes 421 are provided on each carrying rod 42 for installing bolts in the corresponding threaded holes 421 according to the size of the cover plate, so as to limit the relative sliding of the lifting mechanism 40 by clamping the bolts into the L-shaped limiting groove 231.

[0035] In this embodiment, an L-shaped limiting groove 231 is opened on the third sleeve 23, and a bolt is installed on the carrying rod 42. Thus, when the carrying rod 42 is pushed by the rotating handle 41 and the working end of the carrying rod 42 is located on the other side of the cover plate, the carrying rod 42 is rotated by the rotating handle 41 to clamp the bolt in the limiting groove, thereby ensuring that the carrying rod 42 does not slide during the lifting process. Moreover, a number of threaded holes 421 are provided on the carrying rod 42. During actual operation, the length of the extension of the carrying rod 42 can be determined according to the size of the cover plate, and then bolts are installed in the threaded holes 421 at the corresponding positions on the carrying rod 42, so as to realize the lifting operation of cover plates of different sizes.

[0036] In one embodiment, the working ends of the clamping block 43, the lever 30, and the fixing rod 132 are all set to be pointed tips, so that it is more convenient to lift the cover plate by the lever 30, firmly clamp in the brick joints or penetrate into the ground by the fixing rod 132, and clamp on the other side of the cover plate by the clamping block 43.

[0037] When the device is implemented, first move the device near the cable trench cover plate to be lifted and adjust an appropriate spacing. Then, according to the condition of the on-site ground, adjust the extending length of the fixing rod 132 of the first fixing assembly 13 and fix the fixing rod 132 on the ground. For example, insert the tip of the short side of the fixing rod 132 into the brick joint. Then push the lever 30 so that the tip of the working end of the lever 30 is inserted into the cover plate gap of the cover plate, and press the lever 30 downward from the handheld end to lift the cover plate. After the lever 30 lifts the cover plate, push the handling rods 42 on both sides to extend from below the lifted cover plate. At this time, the direction of the clamping block 43 is towards both sides, that is, parallel to the cover plate plane. When the clamping block 43 extends to the other side of the cover plate, rotate the handling rod 42 through the rotating handle 41 so that the clamping block 43 is stuck on the other side of the cover plate, and at the same time, the bolt on the handling rod 42 is inserted into the L-shaped limiting groove 231. Further pressing the lever 30 downward can completely lift the cable trench cover plate.

[0038] The modules or units in the device of the embodiment of the present utility model can be combined, divided, and deleted according to actual needs. The above-disclosed is only a preferred embodiment of the present utility model. Of course, the scope of the rights of the present utility model cannot be limited thereby.
