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

[0002] In existing technologies, due to the compact structure or limited installation space of some equipment, it is impossible to directly transport components using large overhead cranes or hoists. When it is necessary to disassemble or install certain components of the equipment, at least two workers are usually required to operate together. That is, one worker supports the component at its installation location, while the other worker disassembles or tightens the fasteners used to connect the components. When installing heavy components, multiple people are needed to lift them, which is not only labor-intensive but also has a high risk factor.

[0003] Therefore, a hoisting device is needed to reduce the workload of workers and improve their safety during work. Utility Model Content

[0004] The purpose of this utility model is to provide a hoisting device that reduces the workload of workers, improves the safety factor of workers during work, and saves installation space.

[0008] In some embodiments, the horizontal rotation assembly includes a rotating shaft that passes through and is fixed to the fixed base in a vertical direction, and a rotating sleeve that is rotatably connected to the rotating shaft; the boom and the locking assembly are both hinged to the rotating sleeve.

[0009] In some embodiments, the rotating sleeve includes a first rotating sleeve, a second rotating sleeve, and a third rotating sleeve; in the vertical direction, the second rotating sleeve is located between the first rotating sleeve and the third rotating sleeve; one of the first rotating sleeve and the third rotating sleeve is hinged to the locking assembly, and the other is hinged to the boom.

[0010] In some embodiments, the first rotating sleeve, the second rotating sleeve, and the third rotating sleeve are each provided with positioning holes, and the three positioning holes are connected in the vertical direction; the horizontal rotating assembly further includes a positioning shaft, which passes through the three positioning holes in the vertical direction.

[0011] In some embodiments, the locking component has a locking protrusion on the side near the boom, and the boom has a locking groove on the side near the locking component; or, the locking component has a locking groove on the side near the boom, and the boom has a locking protrusion on the side near the locking component; the locking protrusion engages with the locking groove to lock the boom.

[0012] In some embodiments, a positioning block is provided on the side wall of the locking protrusion; when the locking protrusion engages with the locking groove, the positioning block abuts against the side wall of the boom.

[0017] This utility model provides a hoisting device. It includes a fixed base, a boom hinged at one end to the fixed base and capable of circular motion in a vertical plane at the other end, a locking assembly hinged at one end to the fixed base and capable of arc motion in a vertical plane at the other end, a drive assembly on the boom, and a hoisting assembly including a lifting device, connecting the lifting device to the drive assembly. This allows the locking assembly to lock the boom, while the drive assembly moves the lifting device up and down, enabling the hoisting of the component without manual intervention, reducing worker workload and improving safety. Furthermore, when the locking assembly releases the boom, gravity causes the locking assembly, boom, and drive assembly to move downwards relative to the fixed base in an arc motion (i.e., droop). Once fully drooped, the locking assembly and boom fold below the fixed base, saving installation space and avoiding obstruction of worker access or equipment operation. This allows the hoisting device to be installed in confined spaces, improving its applicability. Attached Figure Description

[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. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0027] In this invention, unless otherwise expressly specified and limited, the first feature being "above" or "below" the second feature may include direct contact between the first and second features, or contact between the first and second features not being in direct contact but through another feature between them.

[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] like Figure 1 , Figure 2 As shown, this embodiment provides a hoisting device, which includes: a fixed base 1, a boom 2, a locking component 3, a drive component 4, and a hoisting component 5.

[0030] like Figure 1 , Figure 2 As shown, the structure of the aforementioned fixing base 1 is as follows: The fixing base 1 includes a mounting plate 11 and two fixing plates 12. The mounting plate 11 is arranged vertically and is fixedly connected to a column or other fixed object by fasteners (e.g., bolts). The two fixing plates 12 are arranged perpendicular to the mounting plate 11 (i.e., arranged horizontally) and are fixedly connected to the mounting plate 11. Here, the fixing plates 12 are connected to the mounting plate 11 by means of welding, for example, the fixing base 1 is U-shaped.

[0031] The aforementioned boom 2 is, for example, a rod-shaped structure or a long strip-shaped plate structure. One end of the boom 2 is hinged to the aforementioned mounting base, and the other end can move in an arc within a vertical plane. Specifically, the boom 2 can be directly hinged to one of the fixing plates 12 of the aforementioned fixing base 1, or it can be indirectly hinged to the aforementioned fixing base 1 through other rotating components.

[0032] The aforementioned locking component 3 is, for example, L-shaped. One end of the locking component 3 is hinged to the aforementioned fixed base 1, and the other end can move in an arc within a vertical plane to lock or release the aforementioned boom 2. Specifically, one end of the locking component 3 is, for example, hinged to another fixed plate 12 in the aforementioned fixed base 1, or it can be indirectly hinged to the aforementioned fixed base 1 through other rotating components. Figure 1 Taking the shown perspective as an example, after the locking component 3 locks the boom 2, the boom 2 is set in the horizontal direction; combined with Figure 1 , Figure 2 From the perspective shown, when the locking component 3 moves upward in an arc (i.e., the locking component 3 is lifted), the locking component 3 separates from the boom 2. This causes the boom 2 to move downward in an arc under the action of gravity (i.e., the boom 2 droops). At the same time, the locking component 3 also moves downward in an arc under the action of gravity (i.e., the locking component 3 droops).

[0033] The aforementioned drive assembly 4 is mounted on the boom 2, and the two are connected, for example, by bolts. The drive assembly 4 is, for example, a linear motor or a rotary motor.

[0034] The aforementioned lifting assembly 5 includes a lifting device 51 that is driven and connected to the drive assembly 4. The lifting device 51 is provided with fixing components or fixing holes for connecting to the product to be lifted. The drive assembly 4 can drive the lifting device 51 to perform lifting and lowering movements. It is understood that the drive assembly 4 and the lifting device 51 can be equipped with transmission components, reduction components, or reversing components, etc., according to actual usage requirements; these will not be described in detail here.

[0035] Therefore, in the above-mentioned hoisting device, a fixed base 1 is provided, on which a boom 2, one end of which is hinged to the fixed base 1 and the other end of which can move in a circular motion in a vertical plane, is provided, as well as a locking assembly 3, one end of which is hinged to the fixed base 1 and the other end of which can move in an arc in a vertical plane. A drive assembly 4 is also provided on the boom 2, and a hoisting assembly 5 including a lifting device 51 is provided, connecting the lifting device 51 to the drive assembly 4. In this way, after the locking assembly 3 locks the boom 2, the drive assembly 4 can drive the lifting device 51 to move up and down, thereby realizing the hoisting of the part to be hoisted without the need for manual intervention in the hoisting process, reducing the workload of workers and improving the safety factor of workers during work. In addition, after the locking component 3 releases the boom 2, under the action of gravity, the locking component 3, the boom 2, and the drive component 4 installed on the boom 2 will move downward in an arc relative to the fixed base 1 (i.e., droop). After the locking component 3 and the boom 2 are completely drooped, they fold under the fixed base 1, saving installation space and avoiding affecting the passage of workers or the normal operation of equipment. This allows the lifting device to be installed in a relatively small space, improving the applicability of the lifting device.

[0036] In some embodiments, such as Figure 1 , Figure 2 As shown, the lifting device also includes a horizontal rotating assembly 6. The fixed end of the horizontal rotating assembly 6 is fixed to the fixed base 1, and the movable end can move in an arc within a horizontal plane. The boom 2 and the locking assembly 3 are both hinged to the movable end of the horizontal rotating assembly 6. This allows the boom 2 and locking assembly 3, hinged at this end, to move in an arc within a horizontal plane when the movable end of the horizontal rotating assembly 6 moves in an arc within the horizontal plane. In other words, the drive assembly 4 mounted on the boom 2 and the lifting device 51 driven by the drive assembly 4 can move in an arc within a horizontal plane. This configuration allows the boom 2 of the lifting device to have a larger working range within a horizontal plane, improving the practicality of the lifting device.

[0037] In some embodiments, combined with Figure 3 , Figure 4As shown, the aforementioned horizontal rotating assembly 6 includes a rotating shaft 61 that passes vertically through and is fixed to the fixed base 1, and a rotating sleeve 62 rotatably connected to the rotating shaft 61. The aforementioned boom 2 and locking assembly 3 are both hinged to the rotating sleeve 62. For example, the boom 2 or locking assembly 3 is hinged to the rotating sleeve 62 by providing a groove-shaped connecting portion on the outer wall of the rotating sleeve 62, with one end of the boom 2 or locking assembly 3 disposed within this connecting portion. A pin passes through both the connecting portion and the boom 2 or locking assembly 3 located inside the connecting portion, thus achieving the hinge connection between the rotating sleeve 62 and the boom 2 or locking assembly 3. It is understood that the aforementioned rotating shaft 61 should pass through both fixed plates 12 fixed to the fixed base 1, and the rotating sleeve 62 is disposed between the two fixed plates 12, which are used to limit the rotation sleeve 62 in the vertical direction. Through the above configuration, the boom 2 and locking assembly 3 can be hinged to the horizontal rotation assembly 6, thereby enabling the boom 2 and locking assembly 3 to rotate in the horizontal plane. The structure is simple, easy to manufacture, and easy to install. Furthermore, by configuring the horizontal rotation assembly 6 as a rotating shaft 61 and a rotating sleeve 62, during the lifting process of the above-mentioned lifting device, the operator can manually push the boom 2 to rotate horizontally. The boom 2 can drive the lifting device 51 to rotate horizontally, thus rotating the lifting device 51 and the component to be installed connected to it to a suitable position, facilitating the installation operation of the component. Similarly, when disassembly is required, the horizontal rotation assembly 6 can be used to rotate the lifting device 51 to a suitable position above the component to be disassembled, connecting the lifting device 51 to the component, facilitating the disassembly operation of the component.

[0038] In some embodiments, combined with Figure 3 , Figure 4 As shown, the aforementioned rotating sleeve 62 includes a first rotating sleeve 621, a second rotating sleeve 622, and a third rotating sleeve 623. In the vertical direction, the second rotating sleeve 622 is located between the first rotating sleeve 621 and the third rotating sleeve 623, providing vertical support for both the first rotating sleeve 621 and the third rotating sleeve 622. One of the first rotating sleeve 621 and the third rotating sleeve 623 is hinged to the locking assembly 3, and the other is hinged to the boom 2. In other words, with... Figure 3 or Figure 4Taking the shown perspective as an example, the locking component 3 and the boom 2 can be configured as follows: the locking component 3 is positioned above and hinged to the first rotating sleeve 621, while the boom 2 is positioned below and hinged to the third rotating sleeve 623. With this configuration, when it is necessary to unlock the locking component 3 and the boom 2, both the boom 2 and the locking component 3 must be actively lifted upwards simultaneously, and the locking component 3 and the boom 2 must be manually separated (or only the locking component 3 must be lifted upwards, separating from the boom 2 during the lifting process). Then, under gravity, the locking component 3 and the boom 2 fold downwards. Alternatively, the locking component 3 can be positioned below and hinged to the third rotating sleeve 623, while the boom 2 is positioned above and hinged to the first rotating sleeve 621. With this configuration, when it is necessary to unlock the locking component 3 and the boom 2, the boom 2 must be actively lifted upwards, or the locking component 3 must be actively lowered downwards. At this time, the locking component 3 automatically separates from the boom 2 and folds downwards under gravity, and then the boom 2 folds downwards under gravity.

[0039] In the above-mentioned hoisting device, by setting the structure of the rotating sleeve 62 as a first rotating sleeve 621, a second rotating sleeve 622, and a third rotating sleeve 623, and hinge one of the first rotating sleeve 621 and the third rotating sleeve 623 to the locking component 3 and the other to the boom 2, when one of the first rotating sleeve 621 and the third rotating sleeve 623 is damaged, it is only necessary to disassemble the locking component 3 or the boom 2 and replace the damaged rotating sleeve separately, without having to disassemble the locking component 3 and the boom 2 at the same time and replace the entire rotating sleeve 62. This facilitates maintenance and repair and saves material costs.

[0040] In some embodiments, combined with Figure 3 , Figure 4 As shown, the first rotating sleeve 621, the second rotating sleeve 622, and the third rotating sleeve 623 are all provided with positioning holes 624. The opening direction of the positioning hole 624 is the same as the extension direction of the rotating sleeve 62. In other words, with Figure 3 Taking the shown perspective as an example, the positioning hole 624 extends vertically. The three positioning holes 624 (i.e., the positioning hole 624 on the first rotating sleeve 621, the positioning hole 624 on the second rotating sleeve 622, and the positioning hole 624 on the third positioning sleeve) are connected vertically. Simultaneously, the positions of the three positioning holes 624 should be offset from the rotating shaft 61 passing through the rotating sleeve 62; in other words, the positions of the three positioning holes 624 are deviated from the axis of the rotating sleeve 62 (i.e., not collinear with the axis of the rotating sleeve 62).

[0041] The aforementioned horizontal rotation assembly 6 also includes a positioning shaft 63, which passes vertically through the three positioning holes 624. It is easy to understand that... Figure 3Taking the perspective shown as an example, the upper and lower ends of the positioning shaft 63 are provided with limiting parts to limit itself in the vertical direction after the positioning shaft 63 passes through the three positioning holes 624, so as to prevent the positioning shaft 63 from coming out of the three positioning holes 624.

[0042] In the aforementioned hoisting device, positioning holes 624 communicating vertically are provided on the first rotating sleeve 621, the second rotating sleeve 622, and the third rotating sleeve 623, and a positioning shaft 63 passes through these positioning holes 624. This allows the positioning shaft 63 to position the first rotating sleeve 621, the second rotating sleeve 622, and the third rotating sleeve 623, preventing opposite rotation between the first rotating sleeve 621 and the third rotating sleeve 623 (i.e., one rotating sleeve 62 rotates clockwise while the other rotates counterclockwise). This also prevents the locking assembly 3 from disengaging horizontally after locking with the boom 2, ensuring the locking effect of the locking assembly 3 and improving the reliability and safety of the hoisting device during use. When adjusting the horizontal position, the positioning shaft 63 causes all three rotating sleeves to rotate simultaneously.

[0043] In some embodiments, such as Figure 4 As shown, the locking assembly 3 has a locking protrusion 31 on the side near the boom 2, and the boom 2 has a locking groove 21 on the side near the locking assembly 3. The locking protrusion 31 is, for example, a rectangular block protrusion, which is adapted to the locking groove 21; that is, the shape and size of the locking protrusion 31 are the same as the shape and size of the locking groove 21. When using the lifting device, the locking protrusion 31 and the locking groove 21 engage to lock the boom 2. In other positions (non-horizontal positions), they cannot engage.

[0044] Specifically, in combination Figure 1 , Figure 2 , Figure 4As shown, during use, because one end of the boom 2 is hinged to the fixed base 1, and the fixed base 1 is fixed to other fixed objects, the boom 2 can only perform circular motion in the vertical plane and cannot perform independent horizontal or vertical motion. In other words, if we consider the circular motion as a composite motion of simultaneous horizontal and vertical motion, the horizontal and vertical displacements generated in this composite motion can only occur synchronously and cannot be separated. Therefore, if we select any point on the boom 2 as a reference point, this reference point can only simultaneously undergo horizontal and vertical displacements. When the locking protrusion 31 of the aforementioned locking component 3 is inserted into the locking groove 21 on the boom 2, when the boom 2 performs a downward movement under the action of gravity (i.e., when it makes an arc motion), the inner wall of the locking groove 21 will abut against the outer wall of the locking protrusion 31, and the boom 2 will be limited in the horizontal direction. The reference point on the boom 2 cannot be displaced in the horizontal direction. Since the horizontal and vertical displacements in the composite motion of the arc motion cannot be separated, the reference point on the boom 2 also cannot be displaced in the vertical direction. That is, the boom 2 is also limited in the vertical direction, and the boom 2 cannot continue to perform the downward movement. Thus, the boom 2 is locked by the locking component 3.

[0045] Of course, the positions of the locking protrusion 31 and the locking groove 21 are not fixed. Those skilled in the art can set the locking groove 21 on the side of the locking component 3 near the boom 2 and the locking protrusion 31 on the side of the boom 2 near the locking component 3 according to actual usage requirements. As long as the boom 2 can be locked by engaging the locking protrusion 31 with the locking groove 21.

[0046] In the above-mentioned hoisting device, by setting a locking protrusion 31 on the locking component 3 or the boom 2, and setting a locking groove 21 on the boom 2 or the locking component 3, the boom 2 can be locked by engaging the locking protrusion 31 with the locking groove 21. The structure is simple, easy to use, and easy to manufacture.

[0047] In some embodiments, such as in combination Figure 1 , Figure 4As shown, a positioning block 32 is provided on the side wall of the locking protrusion 31. This positioning block 32 is, for example, a rectangular block structure, and is fixedly connected to the locking protrusion 31 by bolts. Simultaneously, in the vertical direction, the positioning block 32 at least partially protrudes from the side wall of the locking protrusion 31. When the locking protrusion 31 engages with the locking groove 21, the positioning block 32 abuts against the side wall of the boom 2. Through this arrangement, after the locking assembly 3 locks the boom 2 using the locking protrusion 31, the positioning block 32 abuts against the side wall of the boom 2, thereby preventing, to a certain extent, counter-rotation between the boom 2 and the locking assembly 3, thus preventing the locking assembly 3 from disengaging from the boom 2 in the horizontal direction and ensuring the locking effect of the locking assembly 3. It is understood that there can be two positioning blocks 32. The two positioning blocks 32 are respectively set on the opposite side walls of the locking protrusion 31. When the locking protrusion 31 and the locking groove 21 are engaged, the two positioning blocks 32 abut against the opposite side walls of the boom 2, which further prevents the boom 2 and the locking component 3 from rotating in opposite directions, thereby preventing the locking component 3 from separating from the boom 2 in the horizontal direction, and further ensuring the locking effect of the locking component 3.

[0048] In some embodiments, such as Figure 5 As shown, the aforementioned drive assembly 4 includes a drive motor 41 and a take-up reel 42 connected to the output shaft of the drive motor 41. The drive motor 41 is, for example, a rotary motor. The aforementioned lifting assembly 5 also includes a lifting rope 52, one end of which is connected to the lifting device 51, and the other end is connected to the take-up reel 42. The drive motor 41 drives the take-up reel 42 to wind or release the lifting rope 52. It is understood that the term "lifting rope 52" here is only a general description and does not limit the components of the lifting device 51 used for lifting to only rope-like objects. The lifting rope 52 can be a wire rope or a lifting sling, etc. With the above configuration, the drive motor 41 can drive the take-up reel 42 to rotate, thereby gradually winding the lifting rope 52 connected to the lifting device 51 onto the contour of the take-up reel 42 or gradually releasing the lifting rope 52 wound onto the contour of the take-up reel 42, thereby realizing the raising or lowering action of the lifting device 51. The structure is simple and easy to install and use.

[0049] In some embodiments, combined with Figure 4 , Figure 5As shown, the boom 2 has a clearance groove 22. The outline of the clearance groove 22 is, for example, semi-circular or 3 / 4 circular. The opening of the clearance groove 22 faces away from the fixed base 1, and the storage wheel 42 is disposed within the clearance groove 22. It is understood that there should be a gap between the outer outline of the storage wheel 42 and the inner wall of the clearance groove 22. This gap provides space for the suspension rope 52 wound around the outer outline of the storage wheel 42. Of course, in order to provide space for the suspension rope 52 wound around the outer outline of the storage wheel 42, a storage groove can also be formed on the outer outline of the storage wheel 42, around the storage wheel 42, so that the suspension rope 52 can be wound in the storage groove. With the above arrangement, the outer outline of the storage wheel 42 can be located in the extension direction of the boom 2, which facilitates the storage of the suspension rope 52 by the storage wheel 42.

[0050] In some embodiments, such as Figure 5 As shown, the end of the boom 2 furthest from the fixed base 1 is provided with a rope hole 23, through which the lifting rope 52 is threaded. This arrangement prevents the lifting rope 52 from shifting during the lifting process and ensures that the lifting rope 52 can be smoothly stored in the storage wheel 42. It also reduces the swaying of the lifting device 51 during the lifting process to a certain extent, thus improving the practicality of the lifting device.

[0051] In some embodiments, such as Figure 1 , Figure 2 As shown, the lifting device also includes a monitoring component 7 (e.g., a motor controller) mounted on the fixed base 1. The monitoring component 7 is coupled to the drive component 4 (including electrical and signal connections) to control the start or stop of the drive component 4, and to control the drive component 4 to drive the lifting device 51 to rise or fall. This configuration allows workers to start and stop the lifting operation, or control the rise (lifting the component to be lifted from the ground) and fall (placing the disassembled component on the ground) of the lifting device 51 by controlling the monitoring component 7, making it convenient to use and improving the practicality of the lifting device. When the drive component 4 includes a motor, it controls the start, stop, and forward / reverse rotation of the motor.

[0052] 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.
