Description

Technical Field

[0001] This utility model relates to the field of cranes, specifically to an anti-slip drive mechanism for cranes. Background Technology

[0002] In the existing technology, when heavy machinery such as cranes are performing hoisting or moving operations, their drive mechanisms often rely on traditional gear transmission or belt transmission systems.

[0003] A crane end beam drive mechanism (application number: CN202122550751.9) disclosed in Chinese patent includes: an end beam body, a driver, and a wheel set. The wheel set includes a driving wheel set and a driven wheel set located at both ends of the end beam body. An external gear is provided on the outer side of the wheel of the driving wheel set, and the output end of the driver engages with the external gear surface of the driving wheel set. The wheel set is connected to the end beam body via wheel bushings and elastic retaining rings. The beneficial effects of this invention are as follows: by driving the crane horizontally through the engagement of the driver with the external gear surface of the driving wheel set, kinetic energy is directly and effectively transmitted, ensuring smooth operation of the end beam body and eliminating the need for surface finishing of the end beam body; the use of wheel bushings and elastic retaining rings to connect the wheel set to the end beam body results in a simple structure, easy processing, easy installation, and good stability.

[0004] The existing crane structure adopts a fixed transmission structure, which lacks contact area of ​​the contact surface, resulting in insufficient friction between the drive wheel and the driven object. Especially in wet, slippery, inclined or uneven working environments, it is very easy for slippage to occur, which poses a great safety hazard. Summary of the Invention

[0005] To address the shortcomings of existing technologies, this utility model provides an anti-slip drive mechanism for cranes.

[0006] The technical solution of this utility model is as follows:

[0007] This utility model provides an anti-slip drive mechanism for a crane, including a handling beam. The handling beam has two transmission boxes inside. One transmission box has a power motor on one side and a drive wheel connected to the power motor. The other transmission box has a driven wheel outside. Transmission gears are located outside the transmission boxes. A transmission belt is located between the two transmission gears. A transmission block meshing with the transmission wheel is located outside the transmission belt. A sliding strip connected to the transmission block is located outside the transmission belt. A buffer is located outside the handling beam.

[0008] The transmission block has a movable sliding hole on its outside, and a lifting block is slidably disposed inside the movable sliding hole.

[0009] Optionally, the bottom of the processing beam is provided with an adjustment hole, and a support plate is fixedly connected inside the adjustment hole.

[0010] Optionally, the transmission box is fixedly connected to one side of the support plate, the power motor is fixedly connected to the outside of the transmission box, the output end of the power motor extends into the inside of the transmission box, the inside of the transmission box is connected to the driving wheel via a chain, another transmission box with the same structure is connected to the driven wheel, the output end of the transmission box is connected to the transmission gear, and the outside of the transmission gear is gear-shaped.

[0011] Optionally, the transmission belt is located between the two transmission gears, the transmission block is fixedly connected to the outside of the transmission belt at equal intervals, and a protruding strip is fixedly connected to the outside of the transmission block, the protruding strip meshing with the transmission gear.

[0012] Optionally, the transmission belt is slidably connected to the sliding bar, a positioning plate is fixedly connected to the outside of the sliding bar, a positioning wire is provided on the outside of the positioning plate, and the positioning wire passes through the positioning plate and contacts the transmission block.

[0013] Optionally, a retraction spring is provided between the lifting block and the movable sliding hole, and the movement of the sliding bar is provided by an adjusting rod that penetrates into the movable sliding hole. The adjusting rod contacts the lifting block, and the contact parts of the lifting block and the adjusting rod are both inclined surfaces.

[0014] The beneficial effects achieved by this utility model are as follows:

[0015] This invention features a liftable transmission block with protruding strips, allowing the block to form multiple contact points with the surface of the driven object. This significantly increases friction and effectively prevents slippage. By using a sliding strip in conjunction with a transmission belt and controlling the position of the adjusting rod with a positioning screw, the height of the lifting block can be precisely adjusted. This allows the transmission block to automatically adapt to different working conditions, improving the adaptability and stability of the transmission system. Attached Figure Description

Detailed Implementation

[0021] To facilitate understanding of this utility model by those skilled in the art, the specific embodiments of this utility model are described below with reference to the accompanying drawings. Example 1

[0022] like Figure 1-4 As shown, this utility model provides an anti-slip drive mechanism for a crane, including a processing beam 1. The processing beam 1 has two transmission boxes 2 inside. One transmission box 2 has a power motor 3 on one side and a drive wheel 4 connected to the power motor 3. The other transmission box 2 has a driven wheel 5 outside. The transmission box 2 has a transmission gear 201 outside. The two transmission gears 201 are connected to a transmission belt 6. The transmission belt 6 has a transmission block 7 that meshes with the transmission wheel outside. The transmission belt 6 has a sliding strip 8 connected to the transmission block 7 outside. The processing beam 1 has a buffer 9 outside.

[0023] The transmission block 7 has a movable sliding hole 702 on its outside, and a lifting block 703 is slidably arranged inside the movable sliding hole 702.

[0024] This invention features a liftable transmission block 7 with protruding strips 701, enabling the transmission block 7 to form multiple contact points with the surface of the driven object, thereby significantly increasing friction and effectively preventing slippage. A sliding strip 8 works in conjunction with the transmission belt 6, and the position of the adjusting rod 803 is controlled by a positioning screw 802, achieving precise adjustment of the height of the lifting block 703. This allows the transmission block 7 to automatically adapt to different working conditions, improving the adaptability and stability of the transmission system. Example 2

[0025] like Figure 1-2 As shown, an adjustment hole is provided at the bottom of the treatment beam 1, and a support plate 101 is fixedly connected inside the adjustment hole.

[0026] In this embodiment, the transmission box 2 is fixedly connected to one side of the support plate 101, the power motor 3 is fixedly connected to the outside of the transmission box 2, the output end of the power motor 3 extends into the inside of the transmission box 2, the inside of the transmission box 2 is connected to the drive wheel 4 via a chain, another transmission box 2 has the same structure and is connected to the driven wheel 5, the output end of the transmission box 2 is connected to the transmission gear 201, and the outside of the transmission gear 201 is gear-shaped.

[0027] In use, the power motor 3 drives the transmission box 2 to drive the rotation of the drive wheel 4. At the same time, the transmission gear 201 can be used to adjust and control the transmission block 7, thereby making the transmission block 7 and the driven wheel 5 rotate, which facilitates subsequent control of the transmission. Example 3

[0028] like Figure 2-4 As shown, the transmission belt 6 is located between two transmission gears 201, and the transmission blocks 7 are fixedly connected to the outside of the transmission belt 6 at equal intervals. The outside of the transmission blocks 7 is fixedly connected with protruding strips 701, which mesh with the transmission gears 201.

[0029] Specifically, this structure allows for easy adjustment of the position of the transmission block 7 when the transmission gear 201 rotates.

[0030] In this embodiment, the transmission belt 6 is slidably connected to the sliding strip 8, and a positioning plate 801 is fixedly connected to the outside of the sliding strip 8. A positioning wire 802 is provided on the outside of the positioning plate 801, and the positioning wire 802 passes through the positioning plate 801 and contacts the transmission block 7.

[0031] Specifically, the relative position of the sliding bar 8 can be easily adjusted by the contact between the positioning wire 802 and the transmission block 7.

[0032] In this embodiment, a retraction spring 704 is provided between the lifting block 703 and the movable sliding hole 702. The sliding bar 8 is provided with an adjusting rod 803 that penetrates into the movable sliding hole 702. The adjusting rod 803 contacts the lifting block 703, and the contact parts of the lifting block 703 and the adjusting rod 803 are both inclined surfaces.

[0033] Specifically, the retraction spring 704 can be conveniently reset to the inside of the sliding hole 702 after the lifting block 703 extends out of the sliding hole 702. After adjusting the sliding bar 8, the adjusting rod 803 can contact the lifting block 703 to adjust and control the protrusion of the lifting block 703.

[0034] In summary, by rotating the power motor 3 outside the beam 1, and cooperating with the transmission box 2, the power motor 3 can drive the transmission box 2, thereby controlling the transmission of the driving wheel 4, the driven wheel 5, and the protruding strip 701, and achieving controlled transmission in the contact of such objects.

[0035] Its main innovation is that by using the sliding bar 8 to slide outside the transmission belt 6, and in conjunction with the positioning of the external positioning screw 802 of the sliding bar 8, the position of the adjusting rod 803 can be controlled, thereby controlling the height of the lifting block 703. When the transmission block 7 needs to run, the lifting block 703 protrudes outside the driving wheel 4 and the driven wheel 5, so that the transmission block 7 can contact the external object. At this time, there are many contact points, which can achieve the anti-slip function.

[0036] The embodiments of this utility model described above do not constitute a limitation on the scope of protection of this utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the scope of protection of the claims of this utility model.
