A mechanical synchronization device for a rolling mechanism

Abstract

A mechanical synchronization device for a rolling mechanism includes a connecting component, a rotating component, and a rotation limiting component. The connecting component comprises a top connecting component and a middle connecting component. The top connecting component is connected to the loaded item or support unit. The two ends of the middle connecting component are respectively inserted and connected to the rolling unit and the rotating component. The rotating component rotates around its axis. A rotation limiting component is fitted around the rotating component, and the rotating component reciprocates within the rotation limiting component. In application, the loaded item is subjected to traction force, which moves the connecting component. The connecting component then moves the rotation limiting component, which in turn causes the rotating component to rotate. The rotating component then causes the rolling unit to rotate. The connecting component connects and fixes the loaded item and the rolling unit, so no friction is generated between them, thus not affecting the loaded item. Therefore, this design can fix the loaded item and the rolling unit without damaging the loaded item.

Description

Technical Field

[0001] This invention relates to a synchronization device, belonging to the field of bridge product movement technology, and particularly to a mechanical synchronization device for a rolling mechanism. Background Technology

[0002] In mechanical structures, there is an application of a rolling mechanism that can convert sliding friction into rolling friction, thereby reducing frictional force.

[0003] Chinese patent application number 202211630209.7, filed on December 19, 2022, discloses a cargo transportation platform for logistics engineering. It includes a loading platform and four rollers arranged in a rectangular array, which are tumbling on the outside of the loading platform via supports. Baffles are fixedly installed at both the front and rear ends of the loading platform. An expansion mechanism that increases the loading area of ​​the platform is installed between the two baffles, and a transmission mechanism is installed at the bottom of the expansion mechanism. Through the expansion mechanism and the protective mechanism, the user can rotate the opposing threaded rod via a rotating component to expand two sliding plates at the top of the loading platform, increasing the loading area. Simultaneously, during movement, the sliding plates can be activated by a trigger to stand the swing seat and extension frame, protecting the sides of the cargo on the upper part of the loading platform. Although this design can prevent the loading platform from falling due to bumps during transportation, it still has the following drawbacks:

[0004] This design does not secure the loaded item (the cargo mentioned above) to the rolling unit (the loading platform and rollers mentioned above). Therefore, when the rolling unit moves together with the loaded item, the loaded item may slide on the rolling unit, and the friction generated by this sliding may damage the loaded item. Thus, in the prior art, the loaded item is not secured to the rolling unit.

[0026] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0027] 1. In the mechanical synchronization device of the rolling mechanism of the present invention, the device includes a connecting component, a rotating component, and a rotating limiting component. The connecting component includes a top connecting component and a middle connecting component. The top connecting component is connected to the loaded item, one end of the middle connecting component is connected to the rolling unit, and the other end of the middle connecting component is inserted into the rotating component. The rotating component is covered by a rotating limiting component. In application, the movement stroke of the loaded item is to the left or right, thus driving the connecting component to move. The rotating limiting component follows the movement of the connecting component, thereby causing the rotating component to rotate within the rotating limiting component to drive the rolling unit to rotate. The rotation of the rotating component within the rotating limiting component allows the rolling unit to rotate, achieving the effect of reducing the friction between the loaded item and the rolling unit. The connecting component connects the loaded item and the rotating component, enabling the loaded item and the rotating component to move synchronously, so that relative sliding does not occur, thereby avoiding the occurrence of sliding friction and the situation where sliding friction damages the loaded item. Therefore, the present invention can fix the loaded item and the rolling unit without damaging the loaded item.

[0028] 2. In the mechanical synchronization device of the rolling mechanism of the present invention, the top connecting device is an upper fixed plate and a lower fixed plate, the middle connecting device is a middle fixed plate, the rotating device is a rotating shaft, and the rotating limiting device is a connecting plate. The connecting plate is provided with an upper rotating hole, a middle rotating hole, and a lower rotating hole. A rotating shaft is inserted into each of the upper rotating hole, the middle rotating hole, and the lower rotating hole. In application, the lower rotating hole is fixed in position. Loading an item moves the upper rotating hole and the middle rotating hole, and the middle rotating hole then rotates the rolling unit through the rotating shaft. During rotation, the lower rotating hole does not move and serves as the fulcrum during rotation, thus effectively limiting the rotation range of the rotating device. Therefore, the limiting effect of the present invention is good.

[0029] 3. In the mechanical synchronization device of the rolling mechanism of the present invention, the top connecting device is a top connecting hole and a top fixing screw, the middle connecting device is a guide pin, the rotating device is a self-aligning rolling bearing, and the rotating limiting device includes a guide raceway. One end of the guide pin is inserted and connected to the rolling unit, and the other end is connected to the guide raceway through the self-aligning rolling bearing. In application, when the loaded item moves, it drives the guide raceway to move, which in turn drives the guide pin to move, and then the guide pin causes the rolling unit to rotate. At least one roller in the rolling unit has this device at both ends. The top connecting hole and the top fixing screw connect this device to the loaded item, and the guide pin connects this device to the rolling unit, maintaining the synchronous movement of the loaded item and the rolling unit and preventing sliding friction between the loaded item and the rolling unit. Therefore, the present invention has good synchronous movement.

[0030] 4. In the mechanical synchronization device of the rolling mechanism of the present invention, the top connecting device is a rack assembly, the middle connecting device is a gear bore, the rotating device is a gear, and the rotation limiting device is the rack teeth and wheel teeth on the rack assembly. In application, the loaded item drives the rack assembly to move, the rack teeth then drive the wheel teeth to move, and then the wheel teeth cause the gear to rotate, and the gear bore causes the rolling unit to rotate. At least one roller in the rolling unit has this device at both ends. The rack device not only connects the loaded item, this device, and the support unit, but also fixes the rotation range of the gear without hindering the rotation of the gear. Therefore, the rack assembly and the gear have a high degree of fit. Thus, the present invention has a high degree of fit. Attached Figure Description

[0068] The following are supplementary descriptions of the present invention:

[0069] The rolling unit described in this invention is: Please refer to [link / reference]. Figure 17 The rolling unit 14 is used to realize the conversion between linear motion and rolling. The rolling unit 14 is mainly composed of a frame 141, a roller assembly 142 (composed of several rollers 144 arranged side by side in the frame 141 with a predetermined rolling displacement direction, the rollers 144 can be circular or partially circular) and a connecting plate 143. The bottom of the rolling unit 14 is connected to the support unit 15, which is a plane that can provide sufficient support force. The support unit 15 is mainly composed of a pre-embedded base plate 151, a lower support plate 152, and a limiting support 153. The pre-embedded base plate 151, the lower support plate 152, and the limiting support 153 are steel structures. The pre-embedded base plate 151 is fixed to the concrete foundation with pre-embedded bolts. The pre-embedded base plate 151 and the lower support plate 152 are connected by pins. The limiting support 153 is connected to the pre-embedded base plate 151 with bolts.

[0070] The loaded items described in this invention are: Please refer to Figure 17 The loaded item 13 is usually a large cast and welded part, generally a bridge product. In order to meet the engineering requirements, it can move freely in a certain range in front and back (or left and right) under a certain traction force. The loaded item 13 is placed on top of the rolling unit 14. The function of this device is to prevent sliding friction between the loaded item 13 and the rolling unit 14.

[0071] Example 1:

[0072] Please see Figure 1 — Figure 17A mechanical synchronization device for a rolling mechanism, the device comprising a connecting component 1, a rotating component 2, and a rotating limiting component 3; the connecting component 1 includes a top connecting component 11 and a middle connecting component 12, the top connecting component 11 being located at the top or bottom of the connecting component 1; the middle connecting component 12 being located in the middle of the connecting component 1, one end of the middle connecting component 12 being inserted into one end of a rolling unit 14, and the other end of the middle connecting component 12 being inserted into the rotating component 2; the rotating component 2 having a rotating opening 21 in its middle, the middle connecting component 12 being inserted into the rotating opening 21, the rotating component 2 rotating around its axis, and the rotating component 2 being fitted with a rotating limiting component 3; the rotating limiting component 3 having an insertion opening 31, the rotating component 2 being inserted into the insertion opening 31, the rotating component 2 reciprocating within the insertion opening 31.

[0073] In application, first connect and fix the top connecting component 11 to the loaded item 13, then insert and fix the middle connecting component 12 to the rolling unit 14. Then apply traction to the loaded item 13 to move it left or right (or back and forth) as needed. At this time, the loaded item 13 drives the top connecting component 11 to move linearly, and the top connecting component 11 then drives the rotation limiting component 3 to move linearly. The force of the limiting component 3 is then applied to the rotating component 2, so the rotating component 2 rotates within the insertion port 3. The rotating component 2 then transmits the force to the middle connecting component 12 through the rotation port 21. The force on the middle connecting component 12 and the distance between the support point on the support unit 15 form a torque, which then drives the rolling unit 14. The loading unit 14 rotates; the top connecting part 11 fixes the loaded item 13 to the device, and the middle connecting part 12 fixes the rolling unit 14 to the device, thus achieving the fixation between the loading unit 13 and the rolling unit 14. Therefore, there will be no relative displacement between the loading unit 13 and the rolling unit 14, and no sliding friction will be generated, so the loading unit 13 will not be damaged. The rotating part 2 rotates within the rotation limiting part 3, which realizes the effect of converting linear motion into rotational motion. It will not hinder the rotation of the rolling unit 14, making it convenient to use the rolling unit 14 to reduce the friction of the loaded item 13. At the same time, the rotation limiting part 3 restricts the movement range of the rotating part 2, making the movement path of the rotating part 2 stable.

[0079] The basic content is the same as in Example 1, except that:

[0080] Please see Figure 8 — Figure 13The top connecting component 11 consists of a top connecting hole 4 and a top fixing screw 41. Multiple top connecting holes 4 are evenly distributed on the top of the device. The top connecting holes 4 are filled with top fixing screws 41, which are inserted into the loaded item 13. The middle connecting component 12 is a guide pin 5, which includes a large end 51 and a small end 52. The diameter of the large end 51 is larger than the diameter of the small end 52. The large end 51 is inserted into one end of the rolling unit 14. The small end 52, away from the large end 51, is also provided with a pin connecting end 53, the diameter of which is smaller than that of the small end 51. The pin connecting end 53 is fitted with a rotating component 2. The side wall of the small end 52 of the pin is connected to the rotating component 2. The rotating component 2 consists of a self-aligning rolling bearing 54 and a positioning ring 55. The self-aligning rolling bearing 54 includes an inner ring 541 and an outer ring 542. The pin connecting shaft 53 passes through the inner ring 541 to reach the outside of the inner ring 541. An opening groove 56 is provided on the end of the pin connecting shaft 53 away from the self-aligning rolling bearing 54. The positioning ring 55 is located in the opening groove 56. The outer ring 542 of the shaft is fitted with a rotation limiting component 3, which is a guide plate 57.

The middle part of the guide raceway 571 is the highest point. The right part of the guide raceway 571 gradually descends relative to the middle part of the guide raceway 571, and the left part of the guide raceway 571 gradually descends relative to the middle part of the guide raceway 571.

[0081] In application, first align the top connecting hole 4 with the connecting hole on the loading item 13, then place anti-loosening washers on the outside of each top connecting hole 4. Next, insert the top fixing screws 41 through the anti-loosening washers into the top connecting holes 4, thus completing the connection between the device and the loading item 13. Then, insert the large end 51 of the pin into the rolling unit 14 for connection; either an interference fit or a threaded connection is acceptable. Next, fit the inner ring 541 of the self-aligning rolling bearing 54 onto the pin connecting end 53. Finally, install the positioning ring 55 in the opening groove 56. The positioning ring 55 and the shoulder of the small end 52 of the pin are used for... Fix the self-aligning rolling bearing 54, and then insert the self-aligning rolling bearing 54 into the guide raceway 571 to complete the connection and fixation of the device. After applying a traction force to move left and right on the loaded item 13, the top connecting hole 4 and the top fixing screw 41 make the device move left and right with the loaded item 13. At this time, the guide raceway 571 also moves left and right. The force of the guide raceway 571 is applied to the self-aligning rolling bearing 54, and the self-aligning rolling bearing 54 makes the guide pin 3 rotate. The large end 51 of the pin transmits the force to the rolling unit 14, so it drives the rolling unit 14 to rotate.

[0082] Example 4:

[0083] The basic content is the same as in Example 1, except that:

[0084] Please see Figure 14 — Figure 16 The top connecting component 11 is a rack assembly 6, which includes a rack connecting part 61 and a gear part 62. One end of the rack connecting part 61 is connected to one end of the loaded item 13, or one end of the rack connecting part 61 is connected to one end of the support unit 15. The other end of the rack connecting part 61 is connected to one end of the gear part 62. The end of the gear part 62 away from the rack connecting part 61 is connected to the rotating component 2. The middle connecting component 12 is a gear central hole 63, and splines 64 are evenly distributed on the inner surface of the gear central hole 63. The rotating component 2 is a gear 65, the top of which is connected to one gear part 62, and the bottom of which is connected to another gear part 62. The gear central hole 63 is located in the middle of the gear 65. The rotation limiting component 3 consists of a strip tooth 66 and a wheel tooth 67. The strip tooth 66 and the wheel tooth 67 are inserted and connected. Multiple strip teeth 66 are distributed on the outer surface of the strip connecting part 61 near the gear 65, and multiple wheel teeth 67 are evenly distributed on the outer surface of the gear 65.

[0085] Preferably, one end of the gear bore 63 is connected to the positioning cylinder 68.

[0086] In application, first connect and fix the strip connecting part 61 to the bottom of the loaded item 13, then connect and fix the other strip connecting part 61 to the top of the support unit 15. This connection and fixing method can be achieved using a bolt structure. Then, insert and connect the gear central hole 63 to the rolling unit 14. The gear central hole 63 is positioned by the spline 64 and the shoulder of the rolling unit 14. Then, insert and engage the strip tooth 66 and the wheel tooth 67 to complete the connection and fixing of this device. After applying a lateral traction force to the loaded item 13, connect it to the bottom of the loaded item 13. The bar connecting part 61 moves in a straight line, so the bar tooth 66 moves in a straight line. Then the bar tooth 66 applies a force to the wheel tooth 67, causing the wheel tooth 67 to move with the bar tooth 66. The wheel tooth 67 then causes the gear 65 to rotate. Therefore, the gear hole 63 transmits torque to the rolling unit 14 through the spline 64, causing the rolling unit 14 to rotate. The bar connecting part 61, which is connected to the top of the support unit 15, also cooperates with the wheel tooth 67, further limiting the rotation effect of the gear 65 and further preventing relative slippage between the gear 65 and the loaded item 13.
