[0046] Lifting assembly 3, comprising: driving member 31, transmission member 32 and connecting sling 33;

[0047] Driving member 31, transmission member 32 are rotatably arranged on fixed seat 1;

[0048] Connecting sling 33 is wound on driving member 31, and one end is wound on transmission member 32, connecting hanging frame 2 and fixed seat 1.

[0049] In the embodiment, a kind of winding lifting device is given, and the object to be hoisted connected with hanging frame is lifted and hoisted.

In summary, the present application provides a kind of winding lifting device, and the performance is reliable, structure is simple, and has excellent anti-swing performance.

[0050] Preferably, fixed seat 1 and hanging frame 2 are hollowed out up and down.

[0051] In this embodiment, the fixed seat and the hanging frame are both hollowed up and down, which releases the space in the center and the upper part, greatly improves the space utilization of the hoist lifting device, and is especially suitable for scenes with limited space, such as precise industrial production lines where the processed materials need to pass through the center.

[0052] Preferably, referring to Figures 1-3 , the transmission member 32 comprises: a diagonal pull pulley block 321 rotatably arranged at the center of the side of the fixed seat;

[0053] The connecting hoisting rope 33 comprises: a first hoisting rope 33a and a second hoisting rope 33b arranged at intervals on the driving member;

[0054] The first hoisting rope 33a is wound around the diagonal pull pulley block 321 and connects the first end of the side of the hanging frame 2 and the fixed seat 1;

[0055] The second hoisting rope 33b is wound around the diagonal pull pulley block 321 and connects the second end of the side of the hanging frame 2 and the fixed seat 1;

[0056] The connection between the first hoisting rope 33a and the first end of the side of the hanging frame 2 and the connection between the second hoisting rope 33b and the second end of the side of the hanging frame 2 are symmetrically arranged on both sides of the diagonal pull pulley block 321.

[0057] In this embodiment, the connecting hoisting rope is divided into a first hoisting rope and a second hoisting rope, which are wound around the diagonal pull pulley block respectively; then the first hoisting rope is wound around the diagonal pull pulley block and connects the first end of the side of the hanging frame and the fixed seat; the second hoisting rope is wound around the diagonal pull pulley block and connects the second end of the side of the hanging frame and the fixed seat; due to the first hoisting rope and the second hoisting rope, a symmetrical diagonal pull structure is formed on the diagonal pull pulley block, so that the connections of the two ends of the side of the hanging frame are uniformly stressed, and the tilting problem caused by one-end stress is eliminated, further improving the anti-swing performance of the device. It is worth noting that the connections between the first hoisting rope, the second hoisting rope and the two ends of the side of the hanging frame are actually two hoisting points; since the hoisting assembly is symmetrically arranged on both sides of the fixed seat and the hanging frame, there are also two hoisting points at the symmetrical positions, and the four hoisting points are symmetrically arranged in pairs, corresponding to the four endpoints of the hanging frame and the tension of the four hoisting ropes, which are also symmetrically arranged in pairs, so the device has excellent anti-swing performance.

[0058] More preferably, referring to Figures 1-4 , the diagonal pull pulley block 321 comprises: a first diagonal pull pulley 321a and a second diagonal pull pulley 321b;

[0059] The first diagonal pull pulley 321a and the second diagonal pull pulley 321b are coaxially connected in series and arranged at intervals;

[0060] The first suspension rope 33a and the second suspension rope 33b are respectively wound around the first inclined pulley 321a and the second inclined pulley 321b, and then respectively connected to the first end and the second end of the side of the suspension frame 2.

[0061] In this embodiment, the first and second suspension ropes are connected to the first and second inclined fixed pulleys, respectively. Because the first and second inclined fixed pulleys are spaced apart, the path formed by the first suspension rope and the frame is staggered from the path formed by the second suspension rope and the frame, avoiding cross-interference between the first and second suspension ropes on the inclined fixed pulley assembly and further improving the accuracy of the suspension rope movement. Furthermore, because the two paths are staggered, the resulting tensions are also spatially staggered, further improving the device's anti-sway performance in the front-back direction. More preferably, the distance between the first and second fixed pulleys is 50–300 mm to balance the device's anti-sway performance in the front-back direction and the compactness of the structure.

[0062] More preferably, refer to Figures 1-4 The transmission component 32 also includes: a first movable pulley group 322 and a second movable pulley group 323 with identical structures;

[0063] The first movable pulley group 322 is rotatably installed at the connection between the first hoisting rope 33a and the first end of the side of the hoisting frame 2;

[0064] The second movable pulley block 323 is rotatably installed at the connection between the second hoisting rope 33b and the second end of the side of the hoisting frame 2;

[0065] The first suspension rope 33a and the second suspension rope 33b are respectively wound around the first inclined fixed pulley 321a and the second inclined fixed pulley 321b, and then respectively wound around the first movable pulley group 322 and the second movable pulley group 323, and finally connected to the two ends of the side of the fixed base 1.

[0066] In this embodiment, at the connection between the first hoisting rope and the first end of the hoisting frame side, and at the connection between the second hoisting rope and the second end of the hoisting frame side, a first movable pulley group and a second movable pulley group with identical structures are respectively added. The first inclined fixed pulley is combined with the first movable pulley group, which effectively decomposes the tension required to connect the hoisting rope into half of the original force, reduces the workload of the drive component, and enables the drive component to complete the same hoisting task with lower output power, greatly expanding the load capacity and application scenarios of the device.

[0067] More preferably, refer to Figures 1-4 The transmission component 32 also includes: a first fixed pulley 324 and a second fixed pulley 325 corresponding to the first movable pulley group 322 and the second movable pulley group 323, respectively;

[0068] The first fixed pulley 324 and the second fixed pulley 325 are rotatably and symmetrically arranged at both ends of the fixed base 1 and have the same structure.

[0069] The first movable pulley group 322 includes: a first movable pulley and a second movable pulley that are coaxially connected in series and spaced apart;

[0070] The second movable pulley group 323 includes: a third movable pulley and a fourth movable pulley that are coaxially connected in series and spaced apart;

[0071] The first suspension rope 33a is wound around the first inclined fixed pulley 321a, the first movable pulley, the first fixed pulley 324, and the second movable pulley in sequence, and is connected to the first end of the fixed base 1;

[0072] The first suspension rope 33b is wound around the second inclined fixed pulley 321b, the third movable pulley, the second fixed pulley 325, and the fourth movable pulley in sequence, and is connected to the second end of the fixed base 1.

[0073] In this embodiment, taking the first lifting rope as an example, it is sequentially wound around the first inclined fixed pulley, the first movable pulley, the first fixed pulley, and the second movable pulley, and connected to the first end of the fixed base. Because two movable pulleys are used, the first lifting rope can transmit power between the two pulleys during movement, further reducing the tension required to connect the lifting rope to one-quarter of its original value, thus further reducing the workload of the drive components. In addition, in the first and second movable pulley groups, each movable pulley shares a portion of the load, making the force transmission between the lifting rope and the movable pulleys more stable, avoiding vibration or loss of control due to sudden changes in force, and improving the stability and reliability of the device.

[0074] Preferably, a winch lifting device, reference Figures 1-4 It also includes: a connector 4 disposed on one side of the first fixed pulley 324 and the second fixed pulley 325;

[0075] The first fixed pulley 324 and the second fixed pulley 325 are detachably connected to the first and second ends of the fixed base 1 respectively via the connector 4.

[0076] In this embodiment, a connector is added to the first and second fixed pulleys. The first and second lifting ropes are detachably connected to the connector, avoiding complicated installation operations and greatly improving the installation and maintenance efficiency of the device.

[0077] Preferably, the hoisting device further includes: drive components symmetrically arranged on both sides of the fixed base and the hanging frame, and coaxially connected by a connecting shaft.

[0078] In this embodiment, due to the symmetrical arrangement of the hoisting components, the drive components of the hoisting components are also symmetrically arranged on both sides of the fixed seat and the hoisting frame. The first and second hoisting ropes wound on the drive components are also wound on the drive components at symmetrical positions, so that the hoisting lifting device has a total of four hoisting ropes to correspond to the four lifting points of the hoisting frame. The coaxial connection of the drive components with connecting shafts allows the symmetrically arranged drive components to rotate synchronously, thereby driving the four hoisting ropes and the four lifting points to be stressed and move synchronously. The hoisting frame can be subjected to uniform force during the lifting process, improving the anti-sway performance of the device. In addition, since the lifting speed of the four hoisting ropes and the four lifting points is consistent, it can ensure that the device remains level during the lifting process. Specifically, the drive component includes: a drive motor and a hoisting drum connected to the drive motor, with the connecting ropes wound on the hoisting drum; the structure is simple and easy to implement.

[0079] The hoisting device also includes: a hoisting frame and a hoisting protective plate installed on the hoisting frame;

[0080] The hoisting frame is connected to the fixed base at the top and to the hoisting frame at the bottom.

[0081] The lifting protective plate is detachable and installed around the lifting frame to form a protective cavity;

[0082] The hoisting assembly is installed inside the protective cavity.

[0083] In this embodiment, a closed protective cavity is formed in the hoisting device, and the hoisting components are placed inside the protective cavity. This can effectively isolate dust, rainwater, sand, and other corrosive substances from the external environment, significantly reducing the wear and aging of the hoisting components and extending their service life. In addition, the protective cavity formed by the hoisting protective plate can isolate the hoisting components from contact with external personnel, prevent misoperation, and further improve the safety of the operation.

[0085] In this embodiment, a lifting platform is provided, employing any of the aforementioned winch lifting devices. This design is simple in structure, easy to maintain, and highly reliable.

[0086] The aforementioned elevator is based on the aforementioned winch lifting device, and its technical effects and combinations of technical features will not be elaborated further here. The above embodiments only illustrate several implementation methods of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the 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 all fall within the protection scope of this utility model.
