Description

Technical Field

[0001] This utility model relates to the field of lifting devices, and in particular to a beam-type lifting device. Background Technology

[0002] Beam spreaders are suitable for the transfer of large goods. Currently, common beam spreaders mainly consist of a main beam with adjustable-spacing lifting lugs. More complex structures include a general-purpose, modular, expandable, and quickly assembled satellite spreader disclosed in patent document CN119018759A. However, this solution has some practical problems; lateral and longitudinal adjustments are very inconvenient. Utility Model Content

[0003] To solve the above-mentioned technical problems, this utility model provides a beam-type lifting device. This utility model can achieve rapid adjustment of the lateral and longitudinal spans, resulting in higher adjustment efficiency.

[0004] The technical solution adopted by this utility model to solve its technical problem is: a beam-type lifting device, including a longitudinal beam assembly and a transverse beam assembly;

[0005] The longitudinal beam assembly includes a longitudinal beam body and a longitudinal rotation shaft;

[0006] The longitudinal beam body is provided with the longitudinal rotating shaft inside, the longitudinal rotating shaft is rotatably engaged with the longitudinal beam body, at least one end of the longitudinal rotating shaft extends to the outside of the longitudinal beam body, and the two ends of the longitudinal rotating shaft are respectively provided with first thread sections with opposite threads.

[0007] The sidewall of the longitudinal beam body is provided with longitudinal sliding strip holes parallel to the longitudinal rotation axis;

[0008] The crossbeam assembly includes a first slider, a first lug, and a crossbeam body;

[0009] The first threaded segment is threadedly adapted to the first slider;

[0010] The first lifting lug is slidably fitted on the outside of the longitudinal beam body. The first lifting lug is connected to the first slider through the longitudinal sliding strip hole, and the lower part of the first lifting lug is connected to the middle part of the crossbeam body.

[0011] The rotation of the longitudinal axis can drive the first slider to move inside the longitudinal beam body. Since the first slider is fixed to the first lifting lug and the first lifting lug is fixed to the middle of the crossbeam body, the crossbeam body and the slider move together. Since the two first sliders are respectively adapted to the two first threaded sections with opposite directions, the two first sliders move in opposite directions. That is, the distance between the two crossbeam bodies can be adjusted by rotating the longitudinal axis.

[0012] Preferably, the crossbeam assembly includes a horizontal pivot and a second slider;

[0013] The horizontal rotating shaft is rotatably fitted inside the crossbeam body. The two ends of the horizontal rotating shaft are respectively provided with second threaded sections with opposite directions, and the second threaded sections are respectively threadedly adapted to the second slider.

[0014] The side wall of the beam body is provided with a transverse sliding strip hole parallel to the transverse rotation axis;

[0015] The crossbeam body is externally slidably fitted with a second lifting lug, which is connected to the second slider through the transverse sliding slot.

[0016] The rotation of the horizontal axis can drive the second slider to move inside the crossbeam body. Since the second slider is fixed to the second lug, the second lug will move together with the second slider. Since the two second sliders are respectively adapted to two second threaded sections with opposite directions, the two second sliders move in opposite directions. That is, the distance between the two second lugs can be adjusted by rotating the horizontal axis.

[0017] Preferably, the longitudinal beam body is provided with a rack parallel to the longitudinal rotation axis;

[0018] The bottom of the longitudinal beam body is provided with a transmission strip hole parallel to the longitudinal rotation axis;

[0019] The crossbeam assembly includes a drive shaft, a drive gear, a drive bevel gear, and a driven bevel gear;

[0020] The drive shaft passes through the drive bar hole, and the upper end of the drive shaft is rotatably engaged with the first slider. The upper end of the drive shaft is provided with a drive gear that meshes with the rack.

[0021] The lower end of the drive shaft passes through the interior of the crossbeam body, and the drive shaft rotates relative to the crossbeam body. The lower end of the drive shaft is provided with a drive bevel gear.

[0022] A driven bevel gear that meshes with the driving gear is provided in the middle of the horizontal rotating shaft.

[0023] Because the upper end of the drive shaft has a driving gear that meshes with the rack, the movement of the first slider will drive the driving gear to rotate, thus driving the drive shaft to rotate. The lower end of the drive shaft has a driving bevel gear that meshes with the driven bevel gear, thus driving the horizontal rotating shaft to rotate as well. That is, while the vertical rotating shaft drives the two crossbeam bodies to separate or move away, it will also drive the second lifting lug to separate or move away via the drive shaft. This allows for quick switching between large and small cargo, significantly improving the efficiency of the lifting device.

[0024] Preferably, the drive gear includes several coaxially fixed linkage gears, each with a different outer diameter. The rack includes several rack segments corresponding to each linkage gear, with each rack segment sequentially connected end-to-end. By using linkage gears with different outer diameters, the rotational speed will change when they engage with the rack, allowing for rapid speed adjustment to adapt to different length ranges and improve the efficiency of the spreader in lifting goods.

[0025] Preferably, the linkage gears comprise three. This achieves sufficient coverage of variations in movement speed while keeping the structure from becoming overly complex.

[0026] Preferably, a handwheel is provided at the end of the longitudinal rotation shaft located outside the longitudinal beam body. This facilitates manual control of the rotation of the longitudinal rotation shaft.

[0027] Preferably, the first slider is provided with a first linkage pin, the end of which passes through the longitudinal sliding slot to the outside and connects to the first lifting lug. This facilitates connection.

[0028] Preferably, the second slider is provided with a second linkage pin, the end of which passes through the transverse sliding slot and connects to the second lifting lug. This facilitates connection.

[0029] Preferably, the upper surface of the longitudinal beam body is provided with reinforcing ribs to improve the load-bearing capacity of the longitudinal beam body.

[0030] Advantages of this utility model:

[0031] This invention enables rapid adjustment of both the horizontal and vertical spans. Furthermore, through the cooperation of the transmission shaft, the adjustment of the horizontal span is simultaneously achieved with the adjustment of the vertical span, resulting in higher adjustment efficiency.

[0039] To enhance understanding of this utility model, it will be described in further detail below with reference to the accompanying drawings and embodiments. These embodiments are only used to explain this utility model and do not limit the scope of protection of this utility model.

[0040] Example

[0041] like Figure 1 As shown, a beam-type lifting device includes a longitudinal beam assembly and a crossbeam assembly. The longitudinal beam assembly includes a longitudinal beam body 1 and a longitudinal rotating shaft 5. The longitudinal rotating shaft 5 is disposed inside the longitudinal beam body 1 and is rotatably engaged with the longitudinal beam body 1. At least one end of the longitudinal rotating shaft 5 extends to the outside of the longitudinal beam body 1, and the two ends of the longitudinal rotating shaft 5 are respectively provided with first threaded sections 6 with opposite threads. The side wall of the longitudinal beam body 1 is provided with a longitudinal sliding slot 2 parallel to the longitudinal rotating shaft 5. The crossbeam assembly includes a first slider 7, a first lifting lug 8, and a crossbeam body 9. The first threaded sections 6 are threadedly adapted to the first slider 7. The first lifting lug 8 is slidably engaged with the outside of the longitudinal beam body 1. The first lifting lug 8 is connected to the first slider 7 through the longitudinal sliding slot 2, and the lower part of the first lifting lug 8 is connected to the middle part of the crossbeam body 9.

[0042] The rotation of the longitudinal shaft 5 can drive the first slider 7 to move inside the longitudinal beam body 1. Since the first slider 7 is fixed to the first lug 8 and the first lug 8 is fixed to the middle of the crossbeam body 9, the crossbeam body 9 moves together with the slider. Since the two first sliders 7 are respectively adapted to the two first threaded sections 6 with opposite directions, the two first sliders 7 move in opposite directions. That is, by rotating the longitudinal shaft 5, the distance between the two crossbeam bodies 9 can be adjusted.

[0043] The crossbeam assembly includes a horizontal pivot 11 and a second slider 13;

[0044] The horizontal rotating shaft 11 is rotatably fitted inside the crossbeam body 9. The two ends of the horizontal rotating shaft 11 are respectively provided with second threaded sections 12 with opposite directions, and the second threaded sections 12 are respectively threadedly adapted to the second sliders 13.

[0045] The side wall of the beam body 9 is provided with a transverse sliding strip hole 10 parallel to the transverse rotating shaft 11;

[0046] The crossbeam body 9 is externally slidably fitted with a second lifting lug 14, which is connected to the second slider 13 through the transverse sliding slot 10.

[0047] The rotation of the horizontal shaft 11 can drive the second slider 13 to move inside the crossbeam body 9. Since the second slider 13 is fixed to the second lug 14, the second lug 14 will move together with the second slider 13. Since the two second sliders 13 are respectively adapted to two second threaded sections 12 with opposite directions, the two second blocks move in opposite directions. That is, by rotating the horizontal shaft 11, the distance between the two second lugs 14 can be adjusted.

[0048] The longitudinal beam body 1 is provided with a rack 4 that is parallel to the longitudinal rotation axis 5 inside;

[0049] The bottom of the longitudinal beam body 1 is provided with a transmission strip hole 3 parallel to the longitudinal rotation shaft 5;

[0050] The crossbeam assembly includes a drive shaft 15, a drive gear 16, a drive bevel gear 17, and a driven bevel gear 18.

[0051] The drive shaft 15 is provided through the drive bar hole 3, and the upper end of the drive shaft 15 is rotatably engaged with the first slider 7. The upper end of the drive shaft 15 is provided with a drive gear 16 that meshes with the rack 4.

[0052] The lower end of the drive shaft 15 passes through the interior of the crossbeam body 9, and the drive shaft 15 rotates relative to the crossbeam body 9. The lower end of the drive shaft 15 is provided with a drive bevel gear 17.

[0053] The middle part of the horizontal rotating shaft 11 is provided with a driven bevel gear 18 that meshes with the driving gear 16.

[0054] Since the upper end of the drive shaft 15 is equipped with a drive gear 16 that meshes with the rack 4, the movement of the first slider 7 will drive the drive gear 16 to rotate, which in turn will drive the drive shaft 15 to rotate. The lower end of the drive shaft 15 is equipped with a drive bevel gear 17 that meshes with the driven bevel gear 18, which will drive the transverse rotating shaft 11 to rotate together. That is, while the longitudinal rotating shaft 5 drives the two crossbeam bodies 9 to separate or move away, it will also drive the second lifting lug 14 to separate or move away through the drive shaft 15. This allows for quick switching between large and small cargo, significantly improving the efficiency of the lifting equipment.

[0055] The drive gear 16 includes several coaxially fixed linkage gears, each with a different outer diameter. The rack 4 includes several rack segments corresponding to each linkage gear, with each rack segment sequentially connected end-to-end. By using linkage gears with different outer diameters, the rotational speed will change when they engage with the rack 4, allowing for rapid speed adjustment to adapt to different length ranges of goods and improving the efficiency of the spreader in lifting goods.

[0056] The linkage gears consist of three components. This allows for sufficient variation in movement speed without making the structure overly complex.

[0057] A hand crank 19 is provided at the end of the longitudinal rotation shaft 5 located outside the longitudinal beam body 1. This facilitates manual control of the rotation of the longitudinal rotation shaft 5.

[0058] The first slider 7 is provided with a first linkage pin 20, the end of which passes through the longitudinal sliding slot 2 and connects to the first lifting lug 8. This facilitates connection.

[0059] The second slider 13 is provided with a second linkage pin 21, the end of which passes through the transverse sliding slot 10 and connects to the second lifting lug 14. This facilitates connection.

[0060] The upper surface of the longitudinal beam body 1 is provided with reinforcing ribs to improve the load-bearing capacity of the longitudinal beam body.

[0061] Advantages of this utility model:

[0062] This invention enables rapid adjustment of both the horizontal and vertical spans. Furthermore, through the cooperation of the transmission shaft 15, the adjustment of the horizontal span is simultaneously achieved with the adjustment of the vertical span, resulting in higher adjustment efficiency.

[0063] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0064] The embodiments described above are merely illustrative of several implementation methods of this application, 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 application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
