Technical Field

[0001] This utility model relates to the field of cable trench cover hoisting technology, specifically a cable trench cover hoisting trolley. Background Technology

[0002] Cable trench covers are protective devices that cover cable trenches or cable troughs. They are mainly used in urban roads, substations, industrial areas and other places to protect cables, ensure pedestrian safety and beautify the environment, prevent dust, water, mud and other substances from entering the cable trench, and reduce cable corrosion and mechanical damage.

[0003] In daily work, cable trench covers are often opened manually with pry bars. The cover weighs about 100kg, is 1800mm long, 800mm wide, and has a hole spacing of 500mm. This requires a lot of manpower and resources, and workers' hands are also easily injured by the cover.

[0004] In view of this, a cable trench cover hoisting trolley is proposed, which enables workers to open the cover more conveniently, quickly, labor-savingly and safely. Utility Model Content

[0005] The purpose of this utility model is to provide a cable trench cover hoisting trolley to solve the technical problem mentioned in the background art that cable trench covers need to be pried open manually, which requires a lot of manpower and resources, and at the same time, workers' hands are easily injured by the cover.

[0006] The technical solution adopted in this utility model is:

[0007] A cable trench cover hoisting trolley includes a support plate. A hoisting shaft is mounted on the top of the support plate via a rotating assembly. A positioning hole is provided through the outer side of the hoisting shaft. A positioning assembly is installed at the middle of the back of the support plate. The positioning assembly is used to position the hoisting shaft after hoisting. The positioning assembly includes an inclined plate, a positioning groove, and a positioning pin. The inclined plate is installed at the middle of the back of the support plate. The positioning groove is installed at the inclined top of the inclined plate. The positioning pin passes through the positioning groove. A sliding adjustment assembly is installed at one end of the hoisting shaft. A hoisting rope is installed at the bottom of the sliding adjustment assembly. A hook is installed at the bottom end of the hoisting rope.

[0008] Optionally, the rotating assembly includes a mounting groove, a rotating shaft, and a through hole. The mounting groove is located in the middle of the top of the support plate. The rotating shaft is rotatably mounted inside the mounting groove. The through hole passes through the outside of the rotating shaft and is connected to the hoisting shaft by bolts.

[0009] Optionally, a base is installed at the bottom of the support plate, and locking wheels are symmetrically installed at the bottom of the base.

[0010] Optionally, a handle is installed at one end of the lifting shaft.

[0011] Optionally, the sliding adjustment assembly includes a connecting plate, a sliding groove, a through groove, a moving block, and a fixing screw. The bottom of the connecting plate has a sliding groove, and the front and back of the connecting plate have symmetrical through grooves that penetrate the inner wall of the sliding groove. The moving block is slidably installed inside the sliding groove, and the bottom of the moving block is connected to the top of the hoisting rope. The outer side of the connecting plate is installed with a fixing screw through the through groove, and the fixing screw penetrates the interior of the moving block.

[0012] The beneficial effects of this utility model are:

[0013] 1. In this utility model, when the hook is connected to the top hole of the cover plate, and pressure is applied downwards to one end of the lifting shaft using the handle, the handle moves downwards via the rotating assembly, thereby lifting the cover plate at the other end. This makes opening the cover plate faster, easier, and safer. When the other end of the lifting shaft is pressed down, it enters the positioning groove installed by the inclined plate. The positioning groove is installed by the inclined plate and tilts downwards at the same angle as the lifting shaft. Thus, the lifting shaft enters the interior of the positioning groove and is positioned by the positioning pin through the positioning hole. This eliminates the need for workers to continuously apply downward pressure to the lifting shaft, saving workers' energy and preventing workers from accidentally dropping the lifted cover plate.

[0014] 2. In this utility model, the distance between hooks is changed by moving the movable block. After the distance is determined, the fixed screw passes through the inside of the movable block through the through groove, and then passes through the through groove on the other side. Finally, it is fixed by the nut, thereby fixing the movable block. This allows the lifting trolley to lift cover plates of different sizes, improving the flexibility of the lifting trolley.

[0023] Example:

[0024] like Figures 1-4 As shown, a cable trench cover hoisting trolley includes: a support plate 1, a hoisting shaft 10 mounted on the top of the support plate 1 via a rotating assembly, a positioning hole 11 extending through the outer side of the hoisting shaft 10, and a positioning assembly mounted at the middle position of the back of the support plate 1. The positioning assembly is used to position the hoisting shaft 10 after hoisting. The positioning assembly includes an inclined plate 7, a positioning groove 8, and a positioning pin 9. The inclined plate 7 is mounted at the middle position of the back of the support plate 1, the positioning groove 8 is mounted at the inclined top of the inclined plate 7, and the positioning pin 9 extends through the positioning groove 8.

[0025] The support plate 1 provides a position for the installation of the rotating assembly and the positioning assembly. The rotating assembly is connected to the lifting shaft 10, thereby forming a lever structure on the top of the support plate 1. The cover plate is lifted by the lifting trolley. When pressure is applied downward through one end of the lifting shaft 10 using the handle 12, the handle 12 moves downward through the rotating assembly, thereby lifting the cover plate at the other end. At this time, the lifting shaft 10 enters the positioning groove 8 installed by the inclined plate 7. The positioning groove 8 is installed by the inclined plate 7 and tilts downward at the same angle as the downward tilt of the lifting shaft 10, so that the lifting shaft 10 enters the interior of the positioning groove 8. The positioning hole 11 corresponds to the positioning pin 9. The positioning pin 9 passes through the positioning hole 11, thereby positioning the lifting shaft 10 after the cover plate is lifted. It is not necessary for the staff to continuously apply downward pressure to the lifting shaft 10, saving the staff's physical strength and also avoiding the staff's mistake of causing the lifted cover plate to fall.

[0026] The rotating assembly includes a mounting groove 4, a rotating shaft 5, and a through hole 6. The mounting groove 4 is located in the middle of the top of the support plate 1. The rotating shaft 5 is rotatably mounted inside the mounting groove 4. The through hole 6 passes through the outside of the rotating shaft 5 and is connected to the lifting shaft 10 by bolts.

[0027] The rotating shaft 5 in the rotating assembly is rotatably installed inside the mounting groove 4. The lifting shaft 10 passes through the rotating shaft 5 through the through hole 6 and is then fixed by bolts, thereby connecting the lifting shaft 10 to the rotating assembly. This allows the lifting shaft 10 to swing up and down through the rotating assembly, forming a lever assembly, which facilitates the lifting of the cover plate.

[0028] A base 2 is installed at the bottom of the support plate 1, and locking wheels 3 are symmetrically installed at the bottom of the base 2;

[0029] The base 2 is used to increase the bottom area of ​​the support plate 1, making the trolley more stable. It also provides a position for the installation of the locking wheel 3. The locking wheel 3 facilitates the movement of the trolley and can fix it so that it no longer rotates, making the trolley more stable when lifting the cover plate.

[0030] A handle 12 is installed at one end of the lifting shaft 10, and a connecting plate 13 is installed at the other end of the lifting shaft 10;

[0031] The handle 12 is a rubber non-slip handle, which is convenient for use with the lifting shaft 10. The connecting plate 13 is used to install the sliding adjustment component. The sliding adjustment component adjusts the distance between the hooks 19 by sliding on the bottom of the connecting plate 13.

[0032] The bottom of the connecting plate 13 is provided with a sliding groove 14, and the front and back of the connecting plate 13 are symmetrically provided with through grooves 15, which penetrate the inner wall of the sliding groove 14. A moving block 16 is slidably installed inside the sliding groove 14. A fixing screw 17 is installed on the outside of the connecting plate 13 through the through groove 15, and the fixing screw 17 penetrates the inside of the moving block 16.

[0033] The connecting plate 13 provides a position for the opening of the slide groove 14 and the through groove 15. The slide groove 14 is a T-shaped groove that fits into the moving block 16, allowing the moving block 16 to slide stably inside the slide groove 14. The bottom of the moving block 16 is equipped with hooks 19 by the lifting rope 18, so that the distance between the hooks 19 can be changed by the movement of the moving block 16. After the distance is determined, the fixing screw 17 passes through the through groove 15 into the interior of the moving block 16, and then passes through the through groove 15 on the other side, and is then fixed by the nut, thereby fixing the moving block 16. This allows the lifting trolley to lift cover plates of different sizes, improving the flexibility of the lifting trolley.

[0034] A lifting rope 18 is installed at the bottom of the movable block 16, and a hook 19 is installed at the bottom end of the lifting rope 18;

[0035] The lifting rope 18 provides a position for the installation of the hook 19, which connects the cover plate to the lifting trolley by suspending it over the hole at the top of the cover plate, enabling the lifting trolley to lift the cover plate.

[0036] The working principle is as follows: First, the locking wheel 3 is used to move the lifting trolley to the required position, and then the locking wheel 3 is fixed to make the lifting trolley stable in the position. The position of the hook 19 can be changed by moving the moving block 16 to move it to a suitable position. Then, the hook 19 is hung on the lifting point on the top of the cover plate. The operator uses the handle 12 to press the lifting shaft 10 down. Since the lifting shaft 10 is connected to the rotating component on the top of the support plate 1, a lever structure is formed, which makes it easy to lift the cover plate.

[0037] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
