[0021] Example: Figure 1-3 As shown, a lifting tool for electrical installation comprises a trolley 1, a displacement assembly is arranged at the top of the trolley 1, a column 5 is arranged at the output end of the displacement assembly, a mounting frame 11 is fixedly connected to the top of the column 5, a first mounting rod 16 is slidably connected to the left side of the inside of the mounting frame 11, a second fixed pulley 12 is fixedly connected to the rear end of the first mounting rod 16, a first fixed pulley 10 is fixedly connected to the rear side of the top of the column 5, a wire take-up device 9 is arranged at the top of the trolley 1, a connecting rope is arranged at the output end of the wire take-up device 9, and the connecting rope passes through the first fixed pulley 10 and the second fixed pulley 12 in sequence, and the end of the connecting rope is fixedly connected to a lifting tool body 13, a second motor 14 is fixedly connected to the top of the mounting frame 11, a gear 15 is fixedly connected to the output end of the second motor 14, a first rack 17 is meshedly connected to the left side of the gear 15, and the first rack 17 is fixedly connected to the outer side of the first mounting rod 16;

[0022] When the lifting tool body 13 is lifting the electrical conduit, the wire-retracting device 9 works to retract the connecting rope, and then lifts the electrical conduit. When adjusting the position, the second motor 14 works to drive the gear 15 to rotate. The gear 15 acts on the first rack 17 to make the first mounting rod 16 slide back and forth along the mounting frame 11, and then adjust the position of the second fixed pulley 12, so that the position of the lifting tool body 13 is changed, so that the electrical conduit is closer to the installation position, making the installation more convenient.

[0023] Specifically, Figure 1As shown, the displacement assembly includes a first guide rail 2, and the first guide rail 2 is fixedly connected to the top of the trolley 1, the bottom of the column 5 is slidably connected to the outside of the first guide rail 2, the right end of the first guide rail 2 is fixedly connected to the first motor 3, the output end of the first motor 3 is fixedly connected to the threaded rod 4, and the outer side of the threaded rod 4 is threadedly connected to the bottom of the column 5, the first motor 3 drives the threaded rod 4 to rotate when it works, and the rotating threaded rod 4 drives the column 5 to slide on the first guide rail 2 through the thread, thereby changing the lateral position of the lifting tool body 13, facilitating the installation of the electrical conduit, and the electrical conduit can be transported to a certain extent.

[0024] Specifically, Figure 1 As shown, a second guide rail 7 is fixedly connected to the rear side of the top end of the trolley 1, a mounting plate 8 is slidably connected to the outer side of the second guide rail 7, and a wire-taking device 9 is fixedly connected to the top end of the mounting plate 8, a connecting rod 6 is fixedly connected to the front end of the mounting plate 8, and the front end of the connecting rod 6 is fixedly connected to the column 5. When the column 5 moves, the mounting plate 8 is driven to move on the second guide rail 7 through the connecting rod 6, thereby keeping the wire-taking device 9 and the first fixed pulley 10 in a fixed position.

During the rotation of the gear 15, the second rack 19 is driven to move the second mounting rod 18 forward, and the movement directions of the second mounting rod 18 and the first mounting rod 16 are opposite, so that the counterweight 20 is extended to balance the mounting frame 11 and maintain the stability of the device.

[0026] Specifically, Figure 3 As shown, the left and right sides of the mounting frame 11 are fixedly connected with limit rods 21, and the two limit rods 21 are slidably connected to the first mounting rod 16 and the second mounting rod 18 respectively. The first mounting rod 16 and the second mounting rod 18 are installed inside the mounting frame 11 through the limit rods 21 to maintain the stability of the movement of the first mounting rod 16 and the second mounting rod 18.

[0027] Working principle: When the lifting tool body 13 is lifting the electrical conduit, the wire-retracting device 9 works to retract the connecting rope and then lift the electrical conduit. When adjusting the position, the first motor 3 works to drive the threaded rod 4 to rotate. The rotating threaded rod 4 drives the column 5 to slide on the first guide rail 2 through the thread, thereby changing the lateral position of the lifting tool body 13. The second motor 14 works to drive the gear 15 to rotate. The gear 15 acts on the first rack 17 to make the first mounting rod 16 slide back and forth along the mounting frame 11, thereby adjusting the position of the second fixed pulley 12, so that the position of the lifting tool body 13 changes, and the electrical conduit is closer to the installation position. During the rotation of the gear 15, the second rack 19 is driven to make the second mounting rod 18 move forward. The movement directions of the second mounting rod 18 and the first mounting rod 16 are opposite, thereby making the counterweight block 20 extend to balance the mounting frame 11.
