Description

Technical Field

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

[0002] As is well known, slewing bearings have a wide range of applications and play an extremely important role in fields such as engineering machinery, wind power equipment, military equipment, transportation machinery, metallurgical machinery, and scientific research equipment. One of the bottleneck processes in the production of slewing bearings is the assembly process. The most time-consuming, most likely to damage parts, and most dangerous step in the assembly process is the slewing bearing's flipping.

[0003] Currently, in related technologies, a search reveals that a utility model with patent publication number CN211594976U discloses a slewing bearing flipping device, including a first mounting frame, a second mounting frame, a fixing device, a slewing shaft, and a flipping power device; the fixing device is used to fix the slewing bearing; the slewing shaft is disposed between the first mounting frame and the second mounting frame, and the fixing device is connected to the slewing shaft; the flipping power device is connected to the slewing shaft and is used to drive the slewing shaft to rotate, thereby driving the fixing device to rotate around the slewing shaft.

[0004] Regarding the aforementioned technologies, although the coordinated operation of the fixing device and the turning power device has enabled the automated turning of the slewing bearing, effectively avoiding potential damage from manual operation, the inventors have discovered the following shortcomings: the diameter and weight of current slewing bearings vary considerably, ranging from small-diameter lightweight bearings used in small and medium-sized equipment to large-diameter heavy-duty bearings required for large engineering machinery, with a wide range of specifications. However, the existing technology makes it difficult to flexibly adjust the clamping range and clamping force, making it difficult to balance the stability of the fixing with the safety of the workpiece when handling diverse products, thus limiting its application.

[0005] Therefore, it is necessary to propose a slewing bearing overturning device. Utility Model Content

[0006] The purpose of this invention is to provide a slewing bearing overturning device to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, this utility model provides the following technical solution:

[0008] A slewing bearing overturning device, comprising:

[0009] Two bases;

[0010] Two supports are fixedly connected to the base, and an electro-hydraulic actuator is rotatably mounted on one end of each support.

[0011] Two rubber positioning frames are fixedly connected to the output end of the electro-hydraulic actuator, and multiple composite springs are fixedly connected between the rubber positioning frames;

[0012] Two mounting plates are fixedly connected to one end of the support, and a drive motor is fixedly mounted on the mounting plate. A transmission wheel is fixedly connected to the output end of the drive motor.

[0013] Two transmission wheels are fixedly sleeved on the outside of the electro-hydraulic actuator, and the transmission wheels are connected to the transmission wheel 1 via a transmission belt.

[0014] A positioning component is disposed on the outer wall of the base and is used to fix the base in the usage position.

[0015] As a further embodiment of this utility model: the positioning component includes two positioning plates, both of which are symmetrically arranged on the outer wall of the base, and two positioning holes are opened in the positioning plates, and positioning stakes are vertically slidably connected in the positioning holes.

[0016] As a further improvement of this utility model: a constraint ring is provided in the positioning hole of the positioning plate, and the positioning pile is vertically slidably connected to the positioning plate through the constraint ring.

[0017] As a further improvement of this utility model: two mounting slots are symmetrically opened inside the rubber positioning frame, and a positioning roller is rotatably arranged inside the mounting slot, and multiple anti-slip rubber rings are fixedly sleeved on the outside of the positioning roller.

[0018] As a further improvement of this utility model: the bottom of the base is provided with multiple strip grooves, and anti-slip pads are provided in the strip grooves.

[0019] Compared with the prior art, the beneficial effects of this utility model are:

[0020] The electro-hydraulic actuator allows for flexible adjustment of the rubber positioning frame spacing. Combined with the elastic deformation of the composite spring, it adapts to slewing bearings of different diameters and weights, overcoming the limitations of fixed clamping range in traditional devices. Simultaneously, the rubber positioning frame material and the cushioning effect of the composite spring prevent workpiece damage during clamping, ensuring workpiece integrity. The drive motor, through transmission wheel one, transmission belt, and transmission wheel two, rotates the electro-hydraulic actuator and rubber positioning frame, achieving automated flipping and reducing manual risks. The positioning stakes of the positioning component are slidably connected to the positioning plate via a constraint ring, quickly fixing the base and ensuring equipment stability during flipping.

Detailed Implementation

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] The present invention will be further described in detail below with reference to the accompanying drawings.

[0028] Please see Figures 1-4 In this embodiment of the utility model, a slewing bearing overturning device is characterized by comprising:

[0029] Two bases 1;

[0030] Two supports 2 are fixedly connected to the base 1, and an electro-hydraulic actuator 3 is rotatably provided at one end of the support 2;

[0031] Two rubber positioning frames 4 are fixedly connected to the output end of the electro-hydraulic actuator 3, and multiple composite springs 5 ​​are fixedly connected between the rubber positioning frames 4.

[0032] Two mounting plates 6 are fixedly connected to one end of the support 2, and a drive motor 7 is fixedly mounted on the mounting plate 6. The output end of the drive motor 7 is fixedly connected to a transmission wheel 8.

[0033] Two drive wheels 2 9 are fixedly sleeved on the outside of the electro-hydraulic actuator 3, and the drive wheels 2 9 are connected to the drive wheel 1 8 through the drive belt 10.

[0034] A positioning component is disposed on the outer wall of the base 1, which is used to fix the base 1 in the use position.

[0035] In use, the slewing bearing flipping device fixes the base 1 with a positioning component. Then, according to the specifications of the slewing bearing, the electro-hydraulic actuator 3 is activated to adjust the distance between the two rubber positioning frames 4. The composite spring 5 undergoes elastic deformation as the distance changes, providing a buffer force for clamping. When the slewing bearing is placed between the rubber positioning frames 4, the anti-slip rubber ring 15 on the outside of the positioning roller shaft 14 contacts the workpiece surface, reducing friction damage and enhancing clamping friction to prevent slippage. When flipping is required, the drive motor 7 is activated, which drives the transmission wheel 9 to rotate through the transmission wheel 8 and the transmission belt 10, thereby causing the electro-hydraulic actuator 3 and the rubber positioning frames 4 to rotate synchronously, realizing the automatic flipping of the slewing bearing. Furthermore, during the flipping process, the anti-slip rubber pad 16 at the bottom of the base 1 enhances the friction with the ground, further ensuring the overall stability of the equipment in conjunction with the positioning component.

[0036] exist Figures 1-3 The positioning component includes two positioning plates 11, which are symmetrically arranged on the outer wall of the base 1. Two positioning holes are opened in the positioning plates 11, and positioning stakes 12 are vertically slidably connected in the positioning holes. A constraint ring 13 is provided in the positioning holes of the positioning plates 11, and the positioning stakes 12 are vertically slidably connected to the positioning plates 11 through the constraint rings 13.

[0037] The slewing bearing overturning device, through this structural arrangement, forms a multi-support fixed structure with symmetrically distributed positioning plates 11 and positioning piles 12, which can evenly disperse the impact force during equipment operation; the constraint ring 13 not only reduces the sliding friction between the positioning piles 12 and the positioning holes, making the insertion or removal of the positioning piles 12 smoother, but also compensates for installation errors through its own elasticity, ensuring that the positioning piles 12 are in close contact with the ground, effectively preventing the base 1 from tilting or shifting during the overturning operation, and significantly improving the overall installation stability of the equipment.

[0038] exist Figures 1-4 In the middle: two mounting slots are symmetrically opened inside the rubber positioning frame 4, and a positioning roller shaft 14 is rotatably installed in the mounting slot. Multiple anti-slip rubber rings 15 are fixedly sleeved on the outside of the positioning roller shaft 14. Multiple strip grooves are opened at the bottom of the base 1, and anti-slip rubber pads 16 are installed in the strip grooves.

[0039] This slewing bearing tilting device, through its structure, allows the positioning roller 14 to rotate during the placement of the slewing bearing, reducing contact friction between the workpiece and the positioning frame. Combined with the flexible contact of the anti-slip rubber ring 15, it prevents scratches or deformation of the workpiece surface. The high coefficient of friction of the anti-slip rubber ring 15 enhances clamping tightness, preventing the workpiece from slipping during tilting. The anti-slip rubber pad 16 at the bottom of the base 1 further counteracts the horizontal impact force generated during equipment tilting by increasing friction with the contact surface, working in conjunction with the positioning components to improve overall stability and ensure operational safety.

[0040] In this embodiment, the electro-hydraulic actuator 3 and the drive motor 7 are commercially available devices known to those skilled in the art. They can be customized or selected according to actual needs. Here, we are only using them without making any structural or functional improvements, so we will not go into detail here. The electro-hydraulic actuator 3 and the drive motor 7 are both equipped with matching control switches. The installation position of the control switches is selected according to actual usage needs to facilitate operation and control by the operator. The technology is already very mature and can be implemented.

[0041] The implementation principle of the slewing bearing flipping device of this utility model is as follows: First, the operator inserts the positioning stake 12 vertically into the ground by passing it through the positioning hole of the positioning plate 11 and with the guidance of the constraint ring 13. Combined with the anti-slip rubber pad 16 at the bottom of the base 1, this ensures the device is stable and does not shift during operation. Then, according to the specifications of the slewing bearing, the electro-hydraulic actuator 3 is activated to adjust the distance between the two rubber positioning frames 4. The composite spring 5 undergoes elastic deformation as the distance changes, providing a buffer force for clamping. The slewing bearing is then placed between the rubber positioning frames 4, and the anti-slip rubber ring 1 on the outside of the positioning roller shaft 14... 5. Contact with the workpiece surface reduces friction damage and prevents workpiece slippage through friction. When flipping is required, start the drive motor 7. The transmission wheel 8 at its output end drives the transmission wheel 9 to rotate through the transmission belt 10, thereby causing the electro-hydraulic push rod 3 and the rubber positioning frame 4 to rotate synchronously, realizing the automatic flipping of the slewing bearing. During the flipping process, the flexible material of the rubber positioning frame 4 and the buffering effect of the composite spring 5 continuously protect the workpiece and avoid collision damage. After the operation is completed, turn off the drive motor 7, control the electro-hydraulic push rod 3 to reset and release the workpiece, and pull out the positioning stake 12 to move the device.

[0042] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
