[0002] The tapered roller cage is a key component of tapered roller bearings. Its structure typically consists of a basket-shaped cage stamped from steel sheet, with numerous evenly distributed openings inside. During production, storage, and assembly, it frequently needs to be lifted and moved.

[0003] Currently, the common method for lifting is to directly insert wire ropes or ordinary hooks into the inner holes or openings of the cage. This method has significant drawbacks: First, the lifting device and the workpiece are in point or line contact, leading to stress concentration and making the cage prone to deformation or damage to the edges of the openings, affecting product quality. Second, it requires manual and precise adjustment of the lifting device position, resulting in low efficiency. Utility Model Content

It is easy to operate, and the entire hoisting process can be completed remotely by a single person. It is highly efficient, and the workpiece is firmly clamped without the risk of falling off. It is safe and secure. By designing polyurethane positioning blocks that match the shape of the window opening, it provides internal support and even force distribution. It completely avoids the deformation of the cage and surface damage caused by traditional hoisting methods and can effectively solve the problems in the background art.

[0005] To achieve the aforementioned objective, this utility model adopts the following technical solution: A hoisting device for a tapered roller beater includes a hoisting frame with a lifting ring fixed to the top. A guide mechanism is evenly distributed on the disc of the hoisting frame. A push rod is fixed to the movable part of the guide mechanism and is movably connected to the hoisting frame. A positioning block is detachably connected to the end of the push rod, and the positioning block is adapted to a window opening on a retainer. A drive mechanism is installed on the top of the disc of the hoisting frame. A lifting seat is fixed to the lifting part of the drive mechanism, and a guide rod is fixed to the top of the lifting seat. The guide rod is slidably connected to the hoisting frame vertically. The lifting seat is connected to the guide mechanism via a transmission mechanism.

[0006] Furthermore, the guiding mechanism includes a guide groove and a slider. The guide groove is evenly distributed on the disc of the hoisting frame. The slider is slidably connected to the guide groove, and the push rod is fixed to the side of the slider.

[0007] Furthermore, the transmission mechanism includes a first hinge, a connecting rod, and a second hinge. One end of the connecting rod is hinged to the top of the slider via the first hinge, and the other end of the connecting rod is hinged to the bottom of the lifting seat via the second hinge.

[0008] Furthermore, the drive mechanism includes a lead screw, a transmission nut, and a servo motor. The servo motor is mounted on the top of the disc of the hoisting frame. The lead screw is fixed on the output shaft of the servo motor, and the transmission nut is fixed on the lifting seat. The lead screw and the transmission nut are threadedly connected.

[0009] Furthermore, the locking mechanism includes a fastener and a positioning groove. The fastener is fixed to the end of the push rod, and the positioning groove is formed on the positioning block. The fastener and the positioning groove are engaged and locked together.

[0010] Furthermore, the positioning block is a polyurethane block.

Detailed Implementation

[0016] The present invention will be explained in detail through the following embodiments. The purpose of disclosing the present invention is to protect all technical improvements within the scope of the present invention.

[0017] Please see Figure 1-4 This embodiment provides a technical solution: a hoisting device for a conical roller beater, including a hoisting frame 1, a hoisting ring 2 fixed to the top of the hoisting frame 1, a guide mechanism 5 evenly arranged on the disc of the hoisting frame 1, a push rod 7 fixed to the movable part of the guide mechanism 5, the push rod 7 being movably connected to the hoisting frame 1, a positioning block 8 being detachably connected to the end of the push rod 7, the positioning block 8 being adapted to the window hole on the retainer, a drive mechanism 6 installed on the top of the disc of the hoisting frame 1, a lifting seat 9 fixed to the lifting part of the drive mechanism 6, a guide rod 10 fixed to the top of the lifting seat 9, the guide rod 10 being slidably connected to the hoisting frame 1 up and down, and the lifting seat 9 being transmitted to the guide mechanism 5 through a transmission mechanism 3.

[0018] The guiding mechanism 5 includes a guide groove 51 and a slider 52. The guide groove 51 is evenly distributed on the disc of the hoisting frame 1. The slider 52 is slidably connected to the guide groove 51. The push rod 7 is fixed to the side of the slider 52. The transmission mechanism 3 includes a first hinge 31, a connecting rod 32, and a second hinge 33. One end of the connecting rod 32 is hinged to the top of the slider 52 through the first hinge 31, and the other end of the connecting rod 32 is hinged to the bottom of the lifting seat 9 through the second hinge 33. The driving mechanism 6 includes a lead screw 61, a transmission nut 62, and a servo motor 63. The servo motor 63 is mounted on... At the top of the disc of the hoisting frame 1, the lead screw 61 is fixed to the output shaft of the servo motor 63, and the transmission nut 62 is fixed to the lifting seat 9. The lead screw 61 and the transmission nut 62 are threadedly connected. In the initial state, the output shaft of the servo motor 63 drives the lead screw 61 to rotate. The lead screw 61 and the transmission nut 62 are threadedly driven, and the transmission nut 62 drives the lifting seat 9 to move up and down. The lifting seat 9 drives the guide rod 10 to move up and down. The guide rod 10 slides up and down with the hoisting frame 1, so that the lifting seat 9 is in the upper position. The lifting seat 9 pulls the slider 5 through the connecting rod 32. 2. Sliding along the guide groove 51, the slider 52 drives the push rod 7 to move, thereby putting the push rod 7 in a retracted state. During hoisting, the overhead crane is operated to lower the device, aligning the positioning block 8 with the height of the cage window hole. The servo motor 63 is started to reverse the lead screw 61, driving the lifting seat 9 to descend. When the lifting seat 9 descends, it pushes all the sliders 52 to slide outward synchronously along the guide groove 51 through the connecting rod 32, thereby driving all the positioning blocks 8 to open radially and insert into the window hole of the cage. Then, the overhead crane is raised, and the positioning blocks 8 support the inner wall of the window hole from below, leveling the cage. When the device is lifted and placed, the cage is transported to the target position. The servo motor 63 rotates forward, driving the lifting seat 9 to rise. The slider 52 and the positioning block 8 are pulled back into the retracted state through the connecting rod 32, so that the device can be detached from the workpiece. The drive mechanism 6 drives all push rods 7 and positioning blocks 8 to move radially synchronously through the lifting seat 9 and the transmission mechanism 3, which can achieve automatic centering and can simultaneously insert or detach from the window hole of the cage. The action is precise and the operation is simple. The entire lifting process can be completed by a single person remotely. It is highly efficient, and the workpiece is firmly clamped with no risk of falling off, ensuring good safety.

[0019] The snap-fit ​​mechanism 4 includes a fastener 41 and a positioning groove 42. The fastener 41 is fixed to the end of the push rod 7, and the positioning groove 42 is opened on the positioning block 8. The fastener 41 and the positioning groove 42 engage to snap together. Through the cooperation of the fastener 41 and the positioning groove 42, the positioning block 8 can be quickly installed and replaced to adapt to different models of cages, which greatly improves the versatility and usability of the equipment.

[0020] Positioning block 8 is a polyurethane block, which has both hardness and elasticity. It can provide sufficient support strength and effectively avoid scratching or bumping the workpiece surface. By designing polyurethane positioning blocks that match the shape of the window opening, it provides internal support, distributes the force evenly, and completely avoids cage deformation and surface damage caused by traditional hoisting methods.

[0021] The working principle of the hoisting device for a tapered roller beater provided by this utility model is as follows: In the initial state, the output shaft of the servo motor 63 drives the lead screw 61 to rotate. The lead screw 61 and the transmission nut 62 are threadedly driven. The transmission nut 62 drives the lifting seat 9 to move up and down. The lifting seat 9 drives the guide rod 10 to move up and down. The guide rod 10 slides up and down with the hoisting frame 1, so that the lifting seat 9 is in the upper position. The lifting seat 9 pulls the slider 52 along the guide groove 51 through the connecting rod 32. The slider 52 drives the push rod 7 to move, so that the push rod 7 is in the retracted state.

[0022] During hoisting, the overhead crane is used to lower the device so that the positioning block 8 is aligned with the height of the retainer window. The servo motor 63 is started to reverse the lead screw 61, driving the lifting seat 9 to descend. When the lifting seat 9 descends, it pushes all the sliders 52 to slide outward synchronously along the guide groove 51 through the connecting rod 32, thereby causing all the positioning blocks 8 to open radially and insert into the window of the retainer. Then the overhead crane is raised, and the positioning blocks 8 support the inner wall of the window from below, so that the retainer is lifted smoothly.

[0023] When placing the device, the frame will be moved to the target position, the servo motor 63 will rotate forward, driving the lifting seat 9 to rise. The slider 52 and the positioning block 8 will be pulled back into a closed state through the connecting rod 32, so that the device can be separated from the workpiece.
