[0002] The bearing turnover machine between grinding rolls is a widely used piece of equipment in the steel rolling mill workshop of the metallurgical industry. It is mainly used to rotate the bearing housings of work rolls, support rolls, etc., to facilitate the disassembly and installation of bearings within the housings. This turnover machine is fully hydraulically driven and features convenient operation, safety, reliability, and high stability. In actual production, to ensure that the pit is not contaminated or damaged when the turnover machine is not in use, and to provide a safe ground environment for workers, the bearing turnover machine requires a pit cover.

[0003] However, existing bearing turning machines suffer from severe deformation and insufficient load-bearing capacity in their pit covers. Operators must lay scaffolding planks during bearing maintenance, posing a safety hazard. Furthermore, the pit covers must be lifted off by an overhead crane each time the turning machine is used, a cumbersome and time-consuming operation that significantly impacts work efficiency. The pits also lack protection, making them susceptible to contamination and damage.

[0004] Therefore, it is necessary to invent an underground bearing turning machine with a cover plate for protection to solve the above problems. Utility Model Content

The pit frame is constructed using channel steel and steel plates, and is erected and fixed in the workshop, with the box embedded in the pit.

[0008] The load-bearing assembly includes a first load-bearing frame and two symmetrically distributed second load-bearing frames. The two second load-bearing frames are vertically fixed to the bottom of the first load-bearing frame, and a rotating shaft is fixedly connected to both sides of the connection between the first load-bearing frame and the second load-bearing frame. The rotating shaft is rotatably connected to the housing through bearings. A first hydraulic cylinder is movably connected between the housing and the second load-bearing frames through a hinge. The first hydraulic cylinder is connected to a hydraulic drive module, which allows the load-bearing assembly to switch between a lateral state and a longitudinal state.

[0009] The sliding cover is movably mounted on the top of the pit frame via a track, and the outer side of the first support frame is set as an arc surface tangent to the inner wall of the opening. The sliding cover can be switched and adjusted between the first stop position, the second stop position, and the third stop position. The sliding cover can close or partially cover the top of the opening, improving the safety and convenience of operation.

[0010] Preferably, a pad is provided inside the box, and a second hydraulic cylinder is installed on the top of the pad. The connecting end of the second hydraulic cylinder is connected to the control valve through a three-way pipe and is connected to the power supply pipe of the first hydraulic cylinder and the hydraulic drive module. The output end of the second hydraulic cylinder is rotatably connected to a rotating support frame.

[0011] Preferably, a linear motor is installed on the second support frame, and a pressure plate that moves along the length of the second support frame is connected to the top of the linear motor. The rotating support frame is located in the gap between the two second support frames, and the distance between the two pressure plates is greater than the outer diameter of the rotating support frame.

[0012] Preferably, a stop block is fixedly connected to the inner side of the opening of the pit frame, and the load-bearing component can rotate around the pivot axis from 0 to 90° when switching between the lateral and longitudinal states; the bottom wall of the second load-bearing frame in the lateral state abuts against the top wall of the stop block, and the side wall of the first load-bearing frame in the longitudinal state abuts against one of the side walls of the stop block.

[0013] Preferably, a padding layer is provided on the bearing surface of the first bearing frame, and the padding layer is made of rubber blocks.

[0014] Preferably, the width of the sliding cover is greater than the width of the opening, the length of the sliding cover is greater than the difference between the length of the opening and the cross-sectional radius of the first support frame, and the first support frame slides in conjunction with the inner wall of the opening.

[0015] Preferably, the sliding cover is provided with a handrail, a collar is fixedly connected to one side of the sliding cover, a pin is inserted into the collar, and a number of evenly distributed slots are opened on the top of the pit frame, and the pin is engaged with the slot.

[0016] Preferably, the bottom of the sliding cover is provided with rollers, and a drive motor for the transmission rollers is installed on the sliding cover.

During maintenance, the sliding cover can be pulled back to serve as a ramp, allowing workers to access the bearings inside the bearing housing for maintenance or replacement. This provides a safe and efficient working environment in different application scenarios, significantly improving the maintenance efficiency and safety of steel rolling production lines.

[0021] A linear motor drives the pressure plate to move, and the workpiece on the pressure plate moves away from the first support frame, making it capable of rotation. The output end of the second hydraulic cylinder is extended to make the rotating support frame lift the workpiece upward, rotate the workpiece, and change the contact surface with the first support frame, reducing the blind spot between the workpiece and the equipment, and facilitating accurate maintenance.

They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or component referred to must have a specific orientation, or be constructed and operated in a specific orientation. "First," "second," etc., do not indicate the importance of the components, and therefore should not be construed as a limitation of this utility model. The specific dimensions used in this embodiment are only for illustrating the technical solution and do not limit the protection scope of this utility model.

[0036] like Figure 1-5 As shown, an underground bearing turning machine with a cover plate includes a pit frame 1 with a pre-reserved opening, a load-bearing component 4 and a sliding cover plate 7. A box 2 is fixedly connected to the bottom position of the pit frame 1 corresponding to the opening, and a track 3 is laid on the pit frame 1. The pit frame 1 is constructed using channel steel and steel plates, and is erected and fixed in the workshop, with the box 2 embedded in the pit.

[0037] The load-bearing assembly 4 includes a first load-bearing frame 41 and two symmetrically distributed second load-bearing frames 42. The two second load-bearing frames 42 are vertically fixed to the bottom end of the first load-bearing frame 41, and a rotating shaft 43 is fixedly connected to both sides of the connection between the first load-bearing frame 41 and the second load-bearing frame 42. The rotating shaft 43 is rotatably connected to the housing 2 through bearings. A first hydraulic cylinder 5 is movably connected between the housing 2 and the second load-bearing frames 42 through a hinge. The first hydraulic cylinder 5 is connected to a hydraulic drive module 6, which allows the load-bearing assembly 4 to switch between a lateral state and a longitudinal state.

[0038] The sliding cover 7 is movably mounted on the top of the pit frame 1 via the track 3. The outer side of the first support frame 41 is set as an arc surface tangent to the inner wall of the opening. The sliding cover 7 can be switched and adjusted between a first stop position, a second stop position, and a third stop position. The first stop position corresponds to the horizontal state of the support component 4 when it is folded up. When the sliding cover 7 is in the second stop position, it is completely away from the opening area, allowing the support component 4 to be flipped. In the third stop position, the side of the sliding cover 7 is against the workpiece, allowing it to stand as a supporting platform. The sliding cover 7 can close or partially cover the top of the opening, improving the safety and convenience of the operation.

[0039] Yellow and black striped patterns are glued to the outer surfaces of the pit frame 1 and the sliding cover 7 to warn of height differences.

[0040] Specifically, in the above technical solution, a pad 8 is provided inside the housing 2, and a second hydraulic cylinder 9 is installed at the top of the pad 8. The connecting end of the second hydraulic cylinder 9 is connected to the power supply pipeline of the first hydraulic cylinder 5 and the hydraulic drive module 6 via a three-way pipe and a control valve. The output end of the second hydraulic cylinder 9 is rotatably connected to a rotating support frame 10. By extending the output end of the second hydraulic cylinder 9, the rotating support frame 10 lifts the workpiece upward, allowing the workpiece to rotate and change the contact surface with the first support frame 41, reducing the blind spot between the workpiece and the equipment and facilitating maintenance operations.

[0041] Specifically, in the above technical solution, a linear motor 11 is installed on the second support frame 42, and a pressure plate 12 that moves along the length of the second support frame 42 is connected to the top of the linear motor 11. By driving the pressure plate 12 to move through the linear motor 11, the workpiece located on the pressure plate 12 moves away from the first support frame 41, thereby enabling it to rotate.

[0042] The rotating support frame 10 is positioned in the gap between the two second bearing frames 42, and the distance between the two pressure plates 12 is greater than the outer diameter of the rotating support frame 10.

[0043] Specifically, in the above technical solution, a stop block 13 is fixedly connected to the inner side of the opening of the pit frame 1, and the load-bearing component 4 can rotate from 0 to 90° around the pivot 43 when switching between the lateral and longitudinal states; the bottom wall of the second load-bearing frame 42 in the lateral state abuts against the top wall of the stop block 13, and the side wall of the first load-bearing frame 41 in the longitudinal state abuts against one of the side walls of the stop block 13.

[0044] Specifically, in the above technical solution, a pad 14 is provided on the bearing surface of the first support frame 41, and the pad 14 is made of rubber. The pad 14 provides cushioning and protection for the first support frame 41, reducing the impact damage to the first support frame 41 caused by the movement of the sliding cover plate 7 in the storage state, and also has a protective effect on the placement of the workpiece.

[0045] Specifically, in the above technical solution, the width of the sliding cover 7 is greater than the width of the opening, and the length of the sliding cover 7 is greater than the difference between the opening length and the cross-sectional radius of the first support frame 41. The first support frame 41 slides against the inner wall of the opening. When the device is not in use, i.e., when the support component 4 is in the retracted state, the sliding cover 7 and the first support frame 41 can completely cover the opening, protecting the pit from pollution and damage when not in use, and reducing safety hazards in the workshop.

[0046] As one embodiment of the driving method for the sliding cover 7 in the tilting machine, the sliding cover 7 is manually pushed and pulled. Specifically, the sliding cover 7 is provided with a handle 71, and a collar 72 is fixedly connected to one side of the sliding cover 7. A pin 73 is inserted into the collar 72. Several evenly distributed slots 74 are opened on the top of the pit frame 1, and the pin 73 is engaged with the slots 74. When the sliding cover 7 is in the first stop position and the third stop position, it is generally necessary to keep it stable, which can be achieved by locking it with the pin 73.

[0047] As another embodiment of the driving method for the sliding cover 7 in the flipping machine, the sliding cover 7 is driven by mechanical automation. Specifically, as shown in the example... Figure 6 As shown, the bottom of the sliding cover 7 is provided with rollers 75, and the drive motor 76 for the transmission rollers 75 is mounted on the sliding cover 7. The tilting machine also includes a controller 15 and a laser rangefinder 16, wherein the laser rangefinder 16 is mounted at the end of the track 3 for sensing the displacement of the sliding cover 7.

[0048] like Figure 7 As shown, the controller 15 contains a microcontroller 17. The microcontroller 17 has an A / D converter at its input and a D / A converter at its output. The laser rangefinder 16 is electrically connected to the A / D converter, and the hydraulic drive module 6 and the drive motor 76 are both electrically connected to the D / A converter. The laser rangefinder 16 senses the displacement of the sliding cover 7, thereby inferring the position of the sliding cover 7 and positioning it to the first, second, and third stopping positions, enabling automated operation.

[0049] The circuits and controls involved in this application are all prior art and will not be described in detail here.

[0050] The above design not only improves the safety and ease of operation of the surrounding environment of the roller bearing turning machine, but also improves work efficiency and reduces operation time through optimized structural design.

[0051] When using this utility model for maintenance, first open the opening and smoothly move the sliding cover 7 away from above the pit frame 1 to expose the working area of ​​the tilting machine. Then, activate the first hydraulic cylinder 5 via the controller 15 to switch the load-bearing assembly 4 from a horizontal to a vertical position. Hoist the workpiece to be inspected onto the first support frame 41. Next, control the first hydraulic cylinder 5 to switch the load-bearing assembly 4 back to the horizontal position. Then, pull the sliding cover 7 back so that its end abuts against the outer side of the workpiece, acting as a ramp so that operators can access the bearings inside the bearing housing for maintenance or replacement. During the tilting process, the operator monitors the tilting machine's operation to ensure the tilting action is smooth and accurate.

[0052] During external maintenance, in order to facilitate observation of the contact area between the workpiece and the first support frame 41, the pressure plate 12 is moved by the linear motor 11. The workpiece on the pressure plate 12 moves away from the first support frame 41, making it capable of rotation. The output end of the second hydraulic cylinder 9 is extended, causing the rotating support frame 10 to lift the workpiece upward. At this time, the workpiece can be rotated to change the contact surface with the first support frame 41, reducing the blind spot between the workpiece and the equipment and facilitating maintenance operations.

[0053] After the maintenance work is completed, the workpiece is lifted away, and then the sliding cover 7 is reset, the opening is closed, the pit is covered, and the sliding cover 7 is fixed with pin 73 to ensure that the pit is protected when the tilting machine is not in use, preventing debris from falling in.

[0054] The embodiments of this utility model have been described in detail above with reference to the accompanying drawings, but this utility model is not limited to the described embodiments. For those skilled in the art, various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of this utility model, and these variations still fall within the protection scope of this utility model.
