Description

Technical Field

[0001] This utility model relates to the field of cranes, and in particular to a crane with windproof and reinforcement functions for hoisting. Background Technology

[0002] Traditional cranes are prone to safety hazards during lifting operations, especially in windy conditions, due to the swaying of the load or insufficient rigidity of the lifting system. In existing technology, the lifting components of cranes are usually fixed and cannot be adjusted according to actual working conditions. When encountering strong winds, the load swings significantly, which may cause the crane to overturn or the lifting ropes to break.

[0003] Therefore, it is necessary to provide a new type of crane with windproof reinforcement function to solve the above-mentioned technical problems. Utility Model Content

[0004] To overcome the shortcomings of existing technologies, a crane with windproof reinforcement function is provided to solve the above problems.

[0005] The crane with windproof and reinforced hoisting function provided by this utility model includes: a crane; a hoisting box is installed on the top of the crane, and the hoisting box has a hollow structure; wherein, a plurality of hoisting components are arranged inside the hoisting box, and the goods can be hoisted by the hoisting components; an adjustment component is arranged at the bottom of the hoisting box, and the distance between the hoisting components can be adjusted by the adjustment component.

[0006] Preferably, the lifting assembly includes a driving bevel gear rotatably connected to the top wall of the lifting box, and a plurality of driven bevel gears are equidistantly meshed on the bottom edge of the driving bevel gear. A transmission rod is connected to the side of each driven bevel gear away from the driving bevel gear, and the end of each transmission rod away from the driven bevel gear is connected to the inner side wall of the lifting box through a connecting block. A driving component for driving the driving bevel gear to rotate is installed at the top of the lifting box.

[0007] Preferably, a take-up roller is slidably connected to the outer side of each of the transmission rods, and a cable is connected to the outer side of each of the take-up rollers. The bottom of the lifting box is provided with multiple grooves for the cables to pass through, and the end of each cable away from the take-up roller passes through the groove and is connected to a hook.

[0008] Preferably, each of the winding rollers has a guide rod on its inner side, and each of the transmission rods has a guide groove on its outer side for the guide rod to slide.

[0009] Preferably, the adjustment assembly includes a lifting platform disposed below the lifting box, with multiple adjusting rods connected to the periphery of the lifting platform. The number of adjusting rods corresponds to the number of winding rollers. Each adjusting rod has a slide rod connected to its top, and the top of each slide rod passes through a slide groove and is connected to an adjusting ring. An electric push rod for driving the lifting platform to reciprocate is installed at the bottom of the lifting box.

[0010] Preferably, the adjusting ring is sleeved on the outside of the transmission rod, and one side of the adjusting ring is rotatably connected to one side of the take-up roller.

[0011] Compared with related technologies, the crane with windproof reinforcement function provided by this utility model has the following beneficial effects:

[0012] This invention employs a triangular arrangement of lifting components. Its geometric characteristics can decompose the lateral load generated by wind into the tension of the three-sided slings, naturally possessing the ability to resist in-plane swaying. When the spacing between the triangular lifting points is reduced with the adjustment components, the side length of the triangle is shortened, and the resultant force direction of the tension of the three-sided slings is closer to the vertical line, which can effectively suppress the swaying of the suspended object in three-dimensional space.

[0018] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0019] The specific implementation of this utility model will be described in detail below with reference to specific embodiments.

[0020] This utility model provides a crane with hoisting and windproof reinforcement function. The crane with hoisting and windproof reinforcement function includes: a crane 1; a hoisting box 11 is installed on the top of the crane 1, and the hoisting box 11 has a hollow structure; wherein, a plurality of hoisting components are arranged inside the hoisting box 11, and the goods can be hoisted by the hoisting components; an adjustment component is provided at the bottom of the hoisting box 11, and the distance between the hoisting components can be adjusted by the adjustment component.

[0021] It should be noted that: Crane 1, as the basic support structure of the entire equipment, bears the weight of all components such as the lifting box, lifting components, and adjusting components, and provides an operating platform for lifting operations. The lifting components are installed inside the lifting box 11, providing installation space and protection to prevent direct interference from the external environment. The equidistantly distributed lifting components ensure symmetrical lifting points, with the line of gravity passing through the center of the crane, reducing lateral overturning moments. The lifting components are arranged in a triangular configuration, and the adjusting components, by reducing the spacing between the lifting components, enhance the rigidity of the overall lifting system and reduce the sway amplitude under wind conditions.

[0022] In an embodiment of this utility model, the lifting assembly includes a driving bevel gear 2 rotatably connected to the inner top wall of the lifting box 11, and a plurality of driven bevel gears 21 are equidistantly meshed on the bottom edge of the driving bevel gear 2. A transmission rod 22 is connected to the side of each driven bevel gear 21 away from the driving bevel gear 2. The end of each transmission rod 22 away from the driven bevel gear 21 is connected to the inner side wall of the lifting box 11 through a connecting block. A driving component for driving the driving bevel gear 2 to rotate is installed at the top of the lifting box 11. A take-up roller 23 is slidably connected to the outer side of each transmission rod 22. A cable 24 is connected to the outer side of each take-up roller 23. A plurality of grooves for the cable 24 to pass through are opened at the bottom of the lifting box 11. The end of each cable 24 away from the take-up roller 23 passes through the groove and is connected to a hook 25. A guide rod 26 is provided on the inner side of each take-up roller 23. A guide groove 27 for the guide rod 26 to slide is opened on the outer side of each transmission rod 22.

[0023] It should be noted that: the driving bevel gear 2, as the core component for power transmission in the lifting assembly, is rotatably connected to the top wall of the lifting box 11 and rotates under the drive of a motor. The driven bevel gear 21 meshes with the driving bevel gear 2, receives the power transmitted by the driving bevel gear, and rotates. Each driven bevel gear 21 is connected to a transmission rod 22 on the side away from the driving bevel gear 2, transmitting its own rotation to the transmission rod, thereby driving the transmission rod to rotate. Multiple driven bevel gears are equidistantly distributed around the driving bevel gear, enabling multiple transmission rods to rotate synchronously, ensuring the coordination and consistency of the lifting action. The outer side of the winding roller 23 is slidably connected to the transmission rod 22 and can rotate with the rotation of the transmission rod. Its main function is to wind and release the cable 24, and the length of the cable is changed by rotation, thereby controlling the lifting and lowering of the hook 25. The guide rod 26 is located on the inner side of the winding roller 23, and the guide groove 27 is opened on the outer side of the transmission rod 22, with the guide rod 26 sliding within the guide groove 27. Their main function is to ensure that the take-up roller 23 maintains a stable and accurate position during its sliding on the drive rod 22, preventing the take-up roller from shifting or wobbling. The hook 25 connects to one end of the cable 24 and is used to hang goods.

[0024] In an embodiment of this utility model, the adjustment assembly includes a lifting platform 3 disposed below the lifting box 11. A plurality of adjusting rods 31 are connected to the periphery of the lifting platform 3. The number of adjusting rods 31 corresponds to the number of take-up rollers 23. The top of each adjusting rod 31 is connected to a sliding rod 32. The top of each sliding rod 32 passes through a sliding groove and is connected to an adjusting ring 33. An electric push rod for driving the lifting platform 3 to reciprocate is installed at the bottom of the lifting box 11. The adjusting ring 33 is sleeved on the outside of the transmission rod 22. One side of the adjusting ring 33 is rotatably connected to one side of the take-up roller 23.

[0025] It should be noted that: the lifting platform 3, as the basic support component of the adjustment assembly, has multiple adjusting rods 31 connected to its periphery. The adjusting rods 31 connect the lifting platform 3 and the sliding rod 32, transmitting the movement of the lifting platform 3. The sliding rod 32 connects the adjusting rods 31 and the adjusting ring 33, with its top penetrating a groove at the bottom of the lifting box 11. The sliding rod 32 slides within the groove, providing guidance for the movement of the adjusting ring 33, ensuring its accurate movement along the direction of the transmission rod 31; it also transmits the movement of the adjusting rod 31 to the adjusting ring 33. The adjusting ring 33 is fitted onto the outside of the transmission rod 22, with one side rotatably connected to one side of the take-up roller 23. When the adjusting ring 33 moves along the transmission rod 22 under the drive of the sliding rod 32, it pushes the take-up roller 23 to slide on the transmission rod 22, thereby changing the distance between the take-up rollers 23. An electric push rod is installed at the bottom of the lifting box 11, providing power for the reciprocating movement of the lifting platform 3.

[0026] The working principle of the crane with windproof reinforcement function provided by this utility model is as follows: During normal operation, the driving component drives the active bevel gear 2 to rotate, and the driven bevel gear 21 meshes with it to make the transmission rod 22 rotate synchronously. The winding roller 23 is stable on the outside of the transmission rod 22 through the sliding cooperation between the guide rod 26 and the guide groove 27, thereby winding or releasing the cable 24 and controlling the lifting of the hook 25. When encountering strong winds, the electric push rod drives the lifting platform 3 to move upward. The lifting platform 3 drives the slide rod 32 to move upward along the slide groove at the bottom of the lifting box 11 through the adjusting rod 31. The adjusting ring 33 at the top of the slide rod 32 pushes the winding roller 23 to slide towards the center along the transmission rod 22, reducing the spacing of the triangularly arranged winding rollers 23. Because the guide rod 26 and the guide groove 27 restrict the winding roller 23 to move only axially, the side length of the triangular lifting point is shortened, and the resultant force of the sling tension approaches the vertical line, suppressing the swing of the suspended object; after the wind force weakens, the electric push rod drives the lifting platform 3 to descend in the opposite direction, and the adjusting ring 33 drives the winding roller 23 to reset to the initial spacing, adapting to different working conditions.

[0027] The circuits and controls involved in this utility model are all existing technologies, and will not be described in detail here.

[0028] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the content of this utility model specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
