This process involves the horizontal movement and retraction of the lifting cable, which can easily cause the lifting cable to swing and make it difficult to quickly connect the components carrying the steel strip. Utility Model Content

[0003] To address the aforementioned problems, this utility model provides a steel strip hoisting device for armored cables, which can stabilize the position of the hoisting cable and quickly and stably hoist the steel strip.

[0004] The technical solution of this utility model is as follows:

[0006] The hoisting frame includes a base plate, columns, and crossbars, wherein the base plate is located at the bottom of the columns and the crossbars are vertically located at the top of the columns;

[0007] A translation assembly includes a translation mechanism, a mounting plate, and pulleys. The translation mechanism is mounted on a crossbar, and the pulleys are connected to the translation mechanism via the mounting plate.

[0008] A connecting assembly includes a rotating mechanism, a connecting seat, and a connecting head. The rotating mechanism is located on the connecting seat, and the connecting head is located at the bottom of the rotating mechanism and is driven by the rotation of the rotating mechanism. The bottom of the connecting head is provided with an internal threaded hole.

[0009] A winding machine is mounted on a crossbar near one end of a lifting frame. A lifting cable is wound around the winding machine, and the end of the lifting cable passes over the top side of a pulley and is connected to the top of a rotating mechanism.

[0010] The guide assembly includes a slide rail and a slider. The slide rail is vertically disposed on one side of the mounting plate, and the slider is disposed on the connecting seat and slidably connected to the slide rail.

[0011] The support assembly includes a support plate and a connecting post vertically disposed at the top center of the support plate, wherein the top of the connecting post is provided with an external thread that matches an internal threaded hole.

[0012] In a further technical solution, the translation mechanism includes a first motor, a lead screw, and a movable block. A through strip-shaped movable cavity is horizontally opened in the middle of the crossbar. The first motor is located at the end of the crossbar away from the column. One end of the lead screw is connected to the first motor, and the other end is rotatably connected to the inner wall of the strip-shaped movable cavity away from the first motor. The movable block is located on the side of the mounting plate facing away from the pulley, and the movable block has a movable hole in the middle for connecting the lead screw.

[0013] In a further technical solution, the rotating mechanism includes a mounting frame, a second motor, and a reducer.

[0018] The beneficial effects of this utility model are:

[0019] 1. The lifting frame is used to support the various components of the device. The translation component is used to support the lifting cable and move the position of the connecting component horizontally. The connecting component can rotate the connector head through the rotating mechanism to quickly connect the support component by means of threaded connection, and lift and move the support component carrying the steel strip to the designated position. During the lifting of the lifting cable, the slide rail of the guide component guides the connecting seat through the slider, restricts the position of the connecting component, and the lifting cable is not easy to shake.

[0028] The embodiments of this utility model will be further described below with reference to the accompanying drawings.

[0029] Example:

[0030] like Figures 1-3 As shown, a steel strip hoisting device for armored cables includes a hoisting frame, a winding machine 60, a translation component, a connecting component, a support component, and a guide component;

[0031] The hoisting frame includes a base plate 10, a column 20 and a crossbar 30. The base plate 10 is located at the bottom of the column 20 and is used to fix it to the ground. The crossbar 30 is installed with one end perpendicular to the top of the column 20. A strip-shaped movable cavity with front and rear sides is horizontally opened in the middle of the crossbar 30.

[0032] The translation assembly includes a translation mechanism, a mounting plate 45, and a pulley 46. The translation mechanism includes a first motor 41, a lead screw 42, and a movable block 43. The first motor 41 is located at the end of the crossbar 30 away from the column 20. One end of the lead screw 42 is connected to the first motor 41, and the other end is rotatably connected to the inner wall of the strip-shaped movable cavity away from the first motor 41. The movable block 43 is located inside the strip-shaped movable cavity, and its top and bottom sides are slidably connected to the top and bottom walls of the strip-shaped movable cavity, respectively. The movable block 43 has a movable hole 44 in the middle for connecting the lead screw 42. The pulley 46 is located on the side of the mounting plate 45 opposite to the movable block 43.

[0033] The connecting assembly includes a rotating mechanism, a connecting seat 54, and a connecting head 55. The rotating mechanism includes a mounting bracket 51, a second motor 52, and a reducer 53. The mounting bracket 51 is fixedly mounted on the top of the connecting seat 54, and the connecting head 55 is located at the bottom of the connecting seat 54. The second motor 52 is mounted on the mounting bracket 51 and connected to the connecting head 55 through the reducer 53. The second motor 52 can be a stepper motor. One rotation of the second motor 52 can realize the threaded connection and disassembly of the connecting head 55 and the connecting post 82. The bottom of the connecting head 55 is provided with an internal threaded hole 56.

[0034] The winding machine 60 is located on the crossbar 30 near one end of the hoisting frame. The hoisting cable 61 is wound around the winding machine 60. The end of the hoisting cable 61 passes over the top side of the pulley 46 and is connected to the top of the mounting frame 51.

[0035] The guide assembly includes a slide rail 71 and a slider 72. The slide rail 71 is vertically mounted on one side of the mounting plate 45, and the slider 72 is mounted on the connecting seat 54 and is slidably connected to the slide rail 71. The connecting seat 54 is not easily swayed by the lifting cable 61 due to the restriction of the slide rail 71. The length of the slide rail 71 is sufficient to ensure that the connector 55 can stably connect to the connecting column 82.

[0036] The support assembly includes a support plate 81 and a connecting post 82 vertically disposed at the top center of the support plate 81. The top of the connecting post 82 is provided with an external thread that matches the internal thread hole 56. A disc-shaped steel strip 84 can be sleeved on the outside of the connecting post 82 and placed on the support plate 81.

[0037] The top of the external thread of the connecting post 82 and the bottom of the internal thread hole 56 are respectively left with matching unthreaded sections, so that the connector 55 and the connecting post 82 are first smoothly inserted, and then the external thread and the internal thread hole 56 are connected by relative rotation.

[0038] The working principle of the above technical solution is as follows:

[0039] In use, the first motor 41 drives the lead screw 42 to rotate, causing the movable block 43, mounting plate 45, and pulley 46 to move horizontally. When the winding machine 60 is not in operation, the length of the lifting cable 61, which passes around the pulley 46 and hangs down, changes, realizing the lifting and horizontal movement of the connecting component. When the connecting component moves horizontally to directly above the support component, the winding machine 60 releases the lifting cable 61 and lowers the connecting component. During the lowering process, the slider 72 on one side of the connecting seat 54 moves with the slide rail 71 to prevent the connecting component from swinging. After lowering, the internal thread hole 56 of the connector 55 is engaged with the connector. After the connector 55 and the connector 82 are partially inserted at the top of the connector 82, the winding machine 60 continues to release the lifting cable 61, leaving room for relative movement between the connector 55 and the connector 82 during the relative rotation threaded connection. The second motor 52 is started to rotate the connector 55, realizing the threaded connection between the connecting component and the support component. After the connection, the winding machine 60 first retracts part of the lifting cable 61 to raise the connecting component and the support component. Then, using the above method, the connecting component and the support component are moved horizontally by the translation component. After the support component is placed in the designated position, the support component is removed.

[0040] In another embodiment, such as Figure 1 As shown, a counterweight 31 is provided at the end of the crossbar 30 away from the first motor 41.

[0041] Adding a counterweight 31 balances the weight at both ends of the crossbar 30, making the installation of the hoisting frame more stable.

[0042] In another embodiment, such as Figure 1 As shown, the top of the column 20 is provided with a rotating shaft 23 that connects to the crossbar 30. The column 20 is provided with a steering mechanism that drives the rotating shaft 23 to rotate. The steering mechanism includes a third motor 21, a first gear 22 and a second gear 24. The third motor 21 is fixedly provided on one side of the column 20. The first gear 22 is provided on the shaft of the third motor 21 and the second gear 24 is provided on the rotating shaft 23. The first gear 22 and the second gear 24 mesh.

[0043] The third motor 21 drives the first gear 22 to mesh with the second gear 24 to rotate, which can drive the crossbar 30 to turn, increasing the working range of the hoisting device and making it more flexible to use.

[0044] In another embodiment, such as Figure 1 As shown, the bottom of the support plate 81 is provided with a friction pad 83, which can be made of rubber.

[0045] The friction pad 83 helps to increase the friction at the bottom of the support plate 81, preventing the connection plate from rotating relative to the ground due to low friction when the connector 55 rotates relative to the connecting post 82.

[0046] The embodiments described above merely illustrate specific implementations of this utility model, and while the descriptions are detailed, they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these modifications and improvements all fall within the protection scope of this utility model.
