[0004] However, for the new type of electric hoist in the above-mentioned disclosed document, mainly considering the adoption of wireless control, it improves the convenience of operation. It not only can be used without an external power supply during work, but also can measure the weight of the heavy object while lifting the heavy object, and can remind the operator whether the heavy object is overweight. It does not consider that since the electric hoist is suspended at a high place, it will be relatively difficult to carry out maintenance and repair work. Maintenance personnel need to take safety measures such as using safety belts, building scaffolding or using elevators, etc. to reach the installation position of the electric hoist, which not only increases the work difficulty but also raises the safety risk.

[0010] Preferably, the interior of the housing is fixedly provided with multiple sets of frames, and each frame is rotatably provided with a limiting roller for limiting the movement during the winding and unwinding process of the rope.

[0011] Preferably, the base frame has two sets of positioning holes on both sides, the top frame has two sets of outer shells fixedly installed on the top, the outer shells have two sets of rods movably installed at their upper limits, the rods have mounting plates fixedly installed on their exteriors, and the mounting plates are located outside the outer shells, with positioning rods that can cooperate with the positioning holes on the mounting plates.

[0012] Preferably, a lead screw is rotatably mounted inside the outer casing, a lead screw nut is meshed on the lead screw, two sets of connecting rods are fixedly mounted on the lead screw nut, and one end of the connecting rod is fixedly connected to the outside of the rod body. A driven gear is fixedly mounted on the lead screw, and a motor is fixedly mounted inside the outer casing.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] 1. This utility model is equipped with a base frame and a top frame. When the motor is started, its output end drives the second gear to rotate. The second gear meshes with the first gear, thereby driving the winding roller to rotate, so that the rope is wound or unwound. Then, through the connecting frame 2, the electric hoist body is driven to move up and down, making the electric hoist more convenient to maintain, improving maintenance efficiency and the safety of maintenance personnel.

[0015] 2. This utility model, through the installation of the housing, allows the output end of the motor two to drive the drive gear to rotate when the motor two starts. The drive gear, through the driven gear meshing with it, drives the lead screw one to rotate. The rotation of the lead screw causes the lead screw nut to move along the axis of the lead screw, which in turn moves together with the connecting rod and the rod body. The movement of the rod body causes the mounting plate and the positioning rod to move together. When the positioning rod is inserted into the positioning hole on the base frame, the connection and positioning between the top frame and the base frame are realized, ensuring the stability of the electric hoist body on the base frame during normal use.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see Figures 1-5A novel electric hoist includes an electric hoist body 1. A moving mechanism is installed on the top of the electric hoist body 1 to drive the installed electric hoist body 1 to move up and down. The moving mechanism includes a base frame 2 and a top frame 3. The base frame 2 is fixedly installed on the top of the electric hoist body 1, and a connecting frame 4 for connecting to an external frame is fixedly installed on the top of the top frame 3. The electric hoist body 1 is the core part of the entire device, responsible for carrying goods and performing lifting or lowering operations. It includes key components such as a motor, reducer, drum, and wire rope to achieve the hoisting of goods. The connecting frame 4 is a bridge between the top frame 3 and the external frame, allowing the electric hoist body 1 to be installed on the outside for use via the connecting frame 4 on the top frame 3. With the installation of the base frame 2 and the top frame 3, when the motor 11 starts, its output end drives the gear 12 to rotate. The gear 12 meshes with the gear 10, thereby driving the winding roller 8 to rotate, causing the rope 9 to be wound or unwound. This, in turn, drives the electric hoist body 1 to move up and down via the connecting frame 5, making the electric hoist easier to maintain, improving maintenance efficiency and the safety of maintenance personnel.

[0024] Please see Figure 2 and Figure 3 Two sets of connecting frames 5 are fixedly installed on the base frame 2. Two sets of housings 6 are fixedly installed on the top of the top frame 3. A mounting frame 7 is installed inside the housing 6. A winding roller 8 is rotatably mounted on the mounting frame 7. A rope 9 is mounted on the winding roller 8, and one end of the rope 9 is fixedly connected to the connecting frame 5. A gear 10 is fixedly mounted on one end of the winding roller 8. A motor 11 is fixedly installed inside the housing 6. A gear 12 is fixedly mounted on the output end of the motor 11, and the gear 12 meshes with the gear 10. Multiple sets of frames are fixedly installed inside the housing 6. Each frame is rotatably equipped with a limiting roller 13 for limiting the movement of the rope 9 during winding and unwinding. The base frame 2 is fixedly installed on the top of the electric hoist body 1 and is fixedly connected to one end of the rope 9 on the winding roller 8 via the two sets of connecting frames 5 on the base frame 2. The housing 6 is used to accommodate and... To protect the internal mechanical components, the winding roller 8 on the mounting frame 7 is used to wind and unwind the rope 9. When the winding roller 8 rotates, the rope 9 can be wound or unwound accordingly. The limiting roller 13 is used to limit the rope 9 during the winding or unwinding process to prevent the rope 9 from deviating from the predetermined path and ensure the stability of the rope 9's movement trajectory. The motor 11 is the power source for winding or unwinding the rope 9. When the motor rotates, it can drive the rotation of the winding roller 8 through the meshing transmission of the gear 12 and the gear 10. When the motor 11 starts, its output end drives the gear 12 to rotate. The gear 12 meshes with the gear 10, thereby driving the winding roller 8 to rotate, so that the rope 9 is wound or unwound. In turn, the electric hoist body 1 is driven to move up and down through the connecting frame 2 5, making the electric hoist easier to maintain and improving work efficiency and safety.

[0025] Please see Figure 4 and Figure 5 The base frame 2 has two sets of positioning holes 14 on both sides. The top frame 3 has two sets of outer shells 15 fixedly installed on its top. The outer shells 15 have two sets of rods 16 that are movably mounted at their upper limits. The rods 16 have mounting plates 20 fixedly installed on their exteriors, and the mounting plates 20 are located outside the outer shells 15. The mounting plates 20 have positioning rods 24 that can cooperate with the positioning holes 14. The inner shells 15 have a rotatable lead screw 17. The lead screw 17 has a lead screw nut 18 meshing with it. The lead screw nut 18 has two sets of connecting rods 19 fixedly installed on it, and one end of the connecting rod 19 is fixedly connected to the exterior of the rods 16. The lead screw 17 has a driven gear 21 fixedly installed on it. The inner shells 15 have a motor 22 fixedly installed. The output end of the motor 22 is fixedly installed with... There is a drive gear 23, which meshes with the driven gear 21. The outer casing 15 is used to house and protect the internal mechanical components, such as the lead screw and motor. When the motor 22 starts, its output end drives the drive gear 23 to rotate. The drive gear 23 drives the lead screw 17 to rotate through the driven gear 21 meshing with it. The rotation of the lead screw causes the lead screw nut 18 to move along the axis of the lead screw, and then moves together with the connecting rod 19 and the rod body 16. The movement of the rod body 16 will drive the mounting plate 20 and the positioning rod 24 to move together. When the positioning rod 24 is inserted into the positioning hole 14 on the base frame 2, the connection and positioning between the top frame 3 and the base frame 2 are realized, ensuring the stability of the electric hoist body 1 on the base frame 2 during normal use.

[0026] Working principle: Through the installation of the base frame 2 and the top frame 3, when the motor 11 starts, its output end drives the gear 2 12 to rotate. The gear 2 12 meshes with the gear 10, thereby driving the winding roller 8 to rotate, causing the rope 9 to be wound or unwound. This, in turn, drives the electric hoist body 1 to move up and down through the connecting frame 2 5, making the electric hoist easier to maintain, improving maintenance efficiency and the safety of maintenance personnel. When the motor 22 starts, its output end drives the drive gear 23 to rotate. The drive gear 23 drives the lead screw 17 to rotate through the driven gear 21 that meshes with it. The rotation of the lead screw causes the lead screw nut 18 to move along the axis of the lead screw, which in turn moves together with the connecting rod 19 and the rod body 16. The movement of the rod body 16 drives the mounting plate 20 and the positioning rod 24 to move together. When the positioning rod 24 is inserted into the positioning hole 14 on the base frame 2, the connection and positioning between the top frame 3 and the base frame 2 are realized, ensuring the stability of the electric hoist body 1 on the base frame 2 during normal use.
