Description

Technical Field

[0001] This utility model relates to the field of lifting equipment technology, and in particular to a heavy object lifting device. Background Technology

[0002] Cranes are a commonly used type of engineering machinery in engineering operations. Lifting equipment, as part of hoisting equipment, usually refers to the use of lifting machinery to lift objects from one place to another and to install and fix them accordingly, mainly involving the vertical movement of objects.

[0003] When lifting heavy objects in confined spaces, traditional methods typically involve using manual hoists or small mobile cranes. However, these methods can lead to structural stress damage due to the need for temporary pre-embedded lifting points at the top, or the crane boom may not be able to fully extend due to the large size of the equipment, narrow entrances, or limited top space, thus affecting the lifting height.

The drive mechanism and the sliding mechanism are both mounted on the gantry frame, and the lifting mechanism is mounted on the sliding mechanism. The lifting mechanism is used to support the heavy object to be lifted.

[0025] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, the accompanying drawings show only the parts relevant to the present invention, not the entire structure.

[0026] In the description of this utility model, unless otherwise explicitly specified and limited, the terms "connected," "linked," and "fixed" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0027] In this invention, unless otherwise explicitly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0028] In the description of this embodiment, the terms "upper," "lower," "right," etc., refer to the orientation or positional relationship shown in the accompanying drawings. They are used only for ease of description and simplification of operation, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model. In addition, the terms "first" and "second" are only used for distinction in description and have no special meaning.

[0029] Please refer to Figure 1 and Figure 2This embodiment provides a heavy object lifting device, including a gantry frame 1, a drive mechanism 2, a sliding mechanism 3, and a lifting mechanism. The gantry frame 1 includes two parallel and spaced longitudinal beams 11, and a crossbeam 12 fixedly connected between the two longitudinal beams 11. The crossbeam 12 is perpendicular to the longitudinal beams 11. The drive mechanism 2 and the sliding mechanism 3 are both mounted on the gantry frame 1, and the lifting mechanism is mounted on the sliding mechanism 3. The lifting mechanism is used to support the heavy object to be lifted. The drive mechanism 2 and the sliding mechanism 3 are connected by a transmission connection, so that the lifting mechanism can move relative to the gantry frame 1 along the length direction of the longitudinal beams 11. With this configuration, by mounting the drive mechanism 2 and the sliding mechanism 3 on the gantry frame 1 and the lifting mechanism on the sliding mechanism 3, and with the gantry frame 1 providing support, there is no need to pre-embed lifting points in the building structure, thus avoiding the problem of stress damage to the building structure. Meanwhile, by setting up a sliding mechanism 3, the lifting mechanism can move relative to the gantry 1 along the length of the longitudinal beam 11. That is, the device can directly lift heavy objects along the gantry 1 along the length of the longitudinal beam 11. Compared with a crane, it does not need to extend the boom, can adapt to operation in narrow spaces, and the heavy object lifting device has strong versatility.

[0030] Optionally, the sliding mechanism 3 includes two sliding rods 31 and two fixed tubes 32. The two fixed tubes 32 are fixedly connected to the two longitudinal beams 11 in a one-to-one correspondence, and the axial direction of the fixed tubes 32 coincides with the length direction of the corresponding longitudinal beam 11. The two sliding rods 31 are inserted into the two fixed tubes 32 in a one-to-one correspondence, and both sliding rods 31 can slide relative to the wall of the corresponding fixed tube 32. The bracket mechanism is fixedly connected to the sliding rods 31. With this configuration, by sliding the two sliding rods 31 relative to the wall of the corresponding fixed tube 32, and with the bracket mechanism fixedly connected to the sliding rods 31, the lifting mechanism can slide relative to the fixed tube 32 along the length direction of the longitudinal beam 11, thereby realizing the lifting of the heavy object.

[0031] Alternatively, please refer to Figure 2 The length of the sliding rod 31 is greater than the length of the fixed tube 32. This arrangement allows for adjustment of the lifting height of the lifting mechanism, enhancing the versatility of the device. Understandably, the length difference between the sliding rod 31 and the fixed tube 32 represents the maximum lifting stroke of the heavy object lifting device. Those skilled in the art can adaptively adjust the lengths of the sliding rod 31 and the fixed tube 32 according to the available space and lifting requirements; this embodiment does not impose specific limitations on this.

[0032] Optionally, the sliding mechanism 3 further includes two limiting rods 33. One limiting rod 33 is fixedly connected to the first end of the two sliding rods 31, and the other limiting rod 33 is fixedly connected to the second end of the two sliding rods 31. Both limiting rods 33 are parallel to the crossbeam 12. This arrangement prevents the sliding rods 31 from slipping out of the fixed tube 32, which could cause the heavy object to fall, thus improving the safety and reliability of the heavy object lifting device.

[0033] Specifically, the lifting mechanism includes two parallel, spaced-apart lifting arms 4. These two arms 4 support the object to be lifted. Each lifting arm 4 is fixedly connected to the first end of a sliding rod 31, and the lifting arms 4, sliding rods 31, and limiting rods 33 are perpendicular to each other. This arrangement ensures that the object is lifted evenly by the two lifting arms 4, preventing tilting or damage due to uneven force distribution. In other embodiments, the lifting mechanism can also be a lifting platform with a support surface for supporting the object to be lifted. The plane containing the sliding rods 31 and limiting rods 33 is perpendicular to the support surface.

[0034] Optionally, a limiting plate 5 is provided at the end of the lifting arm 4 away from the sliding rod 31. When the lifting arm 4 lifts the object to be lifted, the limiting plate 5 intersects with the lifting arm 4 and is set at an angle. With this setting, during the lifting process, the limiting plate 5 can prevent the object to be lifted from slipping along the length direction of the lifting arm 4, thereby improving the safety and reliability of the lifting device.

[0035] Specifically, the limiting plate 5 and the lifting arm 4 are hinged by a torque hinge so that when the lifting arm 4 lifts the heavy object to be lifted, the limiting plate 5 intersects with the lifting arm 4 and is set at an angle, and is in a limiting state. When the heavy object to be lifted is lifted to a preset position, the limiting plate 5 is rotated to a position consistent with the length direction of the lifting arm 4 by the torque hinge, so that the heavy object can slide relative to the lifting arm 4 to the unloading station.

[0036] Optionally, the object to be lifted can slide relative to the lifting arm 4 along its length. With this configuration, when the object is lifted to a preset position, it can be slid to the unloading station by sliding relative to the lifting arm 4 along its length. Specifically, the surface of the lifting arm 4 is smooth to facilitate the sliding of the object relative to the lifting arm 4 along its length. In other embodiments, a slide rail can also be provided on the lifting arm 4 to allow the object to be lifted to slide relative to the lifting arm 4 along its length.

[0037] Alternatively, please refer to Figure 2 The drive mechanism 2 includes a fixed beam 21, a fixed pulley 22, and a winch 23. The fixed beam 21 is fixedly connected between two longitudinal beams 11. The winch 23 is mounted on the fixed beam 21, and the fixed pulley 22 is mounted on the cross beam 12. The wire rope 231 of the winch 23 passes over the fixed pulley 22 and is connected to the sliding mechanism 3. With this configuration, the wire rope 231 of the winch 23 provides traction, driving the sliding mechanism 3 to move along the length of the longitudinal beams 11, thereby lifting the load. Specifically, the winch 23 is an electric winch for easy operation. In other embodiments, the winch 23 can also be a hydraulic winch, a pneumatic winch, etc.

[0038] Alternatively, please refer to Figure 1 The heavy lifting device also includes a base 6, on which the gantry 1 is mounted. This configuration increases the stability and reliability of the heavy lifting device.

[0039] Optionally, the heavy object lifting device further includes a first reinforcing rod 7. One end of the first reinforcing rod 7 is fixedly connected to the longitudinal beam 11 at an angle, and the other end of the first reinforcing rod 7 is fixedly connected to the base 6 at an angle. This arrangement enhances the structural stability of the heavy object lifting device, especially when lifting heavy objects, preventing the device from deforming or tipping over due to uneven force or external forces. Specifically, the first reinforcing rod 7 is welded between the longitudinal beam 11 and the base 6.

[0040] Optionally, the lifting device further includes a second reinforcing rod 8. One end of the second reinforcing rod 8 is fixedly connected to the sliding mechanism 3 at an angle, and the other end of the second reinforcing rod 8 is fixedly connected to the lifting mechanism at an angle. With this configuration, the second reinforcing rod 8 provides additional support to the lifting mechanism by connecting the sliding mechanism 3 and the lifting mechanism. When the object to be lifted is heavy, it can effectively prevent the lifting mechanism from deforming, thus preventing the object to be lifted from slipping.

[0041] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the present utility model, and are not intended to limit the implementation of the present utility model. Those skilled in the art can make various obvious changes, readjustments, and substitutions without departing from the protection scope of this utility model. It is neither necessary nor possible to exhaustively describe all embodiments here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the protection scope of the claims of this utility model.
