Description

Technical Field

[0001] This utility model relates to the field of gear reversing technology, specifically a reversing support mechanism for an intelligent construction platform. Background Technology

[0002] Gear reversing achieves the switching between forward and reverse rotation of gears through a reversing structure, adapting to various engineering applications requiring automatic reversing. Existing reversing mechanisms add an intermediate gear between the driving and driven gears to change the output direction of the driven gear. When the driving gear rotates forward due to external transmission, the intermediate gear is not used, and the driving and driven gears directly drive each other, with the driven gear outputting in reverse. When the driving gear rotates in reverse due to external transmission, the intermediate gear is installed. This way, the reverse rotation of the driving gear drives the intermediate gear to rotate forward, and the forward rotation of the intermediate gear drives the driven gear to output in reverse, achieving reverse output regardless of whether the driving gear rotates forward or reverse. However, gear reversing mechanisms using intermediate gears require manual disassembly and assembly, which is difficult to operate, demands high worker skills, and has a complex structure. Therefore, reversing mechanisms that can change direction without insertion have emerged, such as the gear steering reversing mechanism disclosed in patent publication number CN219795984U. However, the structure of this reversing mechanism is still relatively complex, including a first ratchet, a second ratchet, a first inverted V-shaped hole, a second inverted V-shaped hole, a first bolt, a second bolt, and a pawl shifting rod. By pulling the pawl shifting rod, the counterclockwise or clockwise rotation of the carrying gear can be adjusted, thereby achieving the steering reversal of the carrying gear. The structure of this reversing mechanism is still relatively complex, increasing the difficulty in manufacturing, assembly, and maintenance. Utility Model Content

[0003] The purpose of this invention is to provide a reversing support mechanism for an intelligent construction platform to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a reversing support mechanism for an intelligent construction platform, comprising a reversing box, the reversing box comprising two bottom plates arranged vertically, and two side plates arranged side-by-side between the two bottom plates, a horizontally arranged first pin connecting the middle of the two side plates, the first pin connecting a gear, the gear being rotatably disposed between the two side plates, a horizontally arranged second pin connecting the top of the two side plates, the second pin connecting a stop for limiting the rotation direction of the gear, two first insertion holes arranged side-by-side between the first and second pins on each side plate, the two first insertion holes on each side plate being symmetrical about the center line connecting the first and second pins, the two first insertion holes on the two side plates being respectively matched and fitted, the first insertion hole being adapted to a reversing shaft, and the gear rotation direction being limited to upward or downward rotation after the reversing shaft is inserted into different first insertion holes, and a snap-fit ​​plate with a rectangular groove being connected to the rear side of each of the two side plates.

[0005] In a further preferred embodiment, the slots of the two snap-fit ​​plates are arranged opposite each other, and the upper and lower ends of the two snap-fit ​​plates are respectively snapped onto the upper and lower base plates. A reinforcing plate is snapped into the middle of each of the two snap-fit ​​plates. The opposite arrangement of the slots ensures that the snap-fit ​​plates can be snapped onto and limited by the climbing guide rail. The reinforcing plate can improve the structural robustness of the high-speed commutator box.

[0006] Further preferably, each of the two side plates has a first mounting hole in the middle for mounting the first pin, and each of the two side plates has a second mounting hole on the top for mounting the second pin, which facilitates the installation of the first pin and the second pin.

[0007] Preferably, each of the two side plates is provided with a second insertion hole. The second insertion hole is located below the middle of the two first insertion holes on the corresponding side plate and above the first mounting hole. The distance between the second insertion hole and the corresponding first mounting hole is greater than the distance between the bottom of the gear tooth groove and the first pin. By providing the second insertion hole, the pin can be inserted into the gear tooth groove, completely restricting the rotation of the gear and ensuring that the gear does not rotate in any direction, thus achieving the goal of fixing the position of the reversing support mechanism relative to the climbing guide rail.

[0008] Preferably, at least one of the two side plates is equipped with a proximity switch. The distance between the proximity switch and the first pin is greater than the distance between the bottom of the gear tooth groove and the first pin, and the distance between the proximity switch and the first pin is less than the distance between the top of the gear tooth and the first pin. The proximity switch can detect the number of teeth rotating on the gear, facilitating the control of the gear's lifting height relative to the climbing guide rail.

[0009] Further preferably, each of the two side plates has a third mounting hole and a fourth mounting hole at its upper and lower ends, respectively. A third pin is installed in each of the two corresponding third mounting holes on the two side plates, and a fourth pin is installed in each of the two corresponding fourth mounting holes on the two side plates. The third and fourth pins can strengthen the connection between the two side plates and, as backups, can be used to connect to other structures, such as connecting to the platform of the intelligent construction platform via a connecting rod, or connecting to a drive device, etc.

[0010] In a further preferred embodiment, each of the two base plates is provided with a through hole, and one of the upper and lower ends of the reversing box is connected to a driving device. The driving device includes a hydraulic cylinder to drive the reversing support mechanism to move up and down along the climbing guide rail.

[0011] Beneficial Effects: The intelligent construction platform of this utility model uses a reversing support mechanism. Through the structural arrangement of gears, blocks, first insertion holes, and reversing shafts, it realizes the rotational reversal of gears, ultimately achieving the reversal of the lifting and lowering motion of the intelligent construction platform. Specifically, when the reversing shaft is inserted into the first insertion hole on the front side, the block can be limited to rotate forward, at which time the gear can rotate upward along the climbing guide rail; when the reversing shaft is inserted into the first insertion hole on the rear side, the block can be limited to rotate backward, at which time the gear can rotate downward along the climbing guide rail; and when the reversing shaft is inserted into... When the first socket on the front side is in place, it can provide support without rotating the gear. At the same time, by setting a second socket and inserting a pin inside it, the rotation of the gear can also be restricted, so that the reversing support mechanism can remain stationary relative to the climbing guide rail, thus providing a support effect. The reversing support mechanism is ingeniously designed, easy to install, simple to operate, and has a simpler structure, making it easier to manufacture, assemble, and maintain. Moreover, reversing can be achieved without changing the structure of the reversing support mechanism, driving the platform of the intelligent construction platform to rise and fall, which can reduce time waste and disassembly and assembly costs.

Detailed Implementation

[0021] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments. Example

[0022] like Figure 1-8As shown, a reversing support mechanism for an intelligent construction platform is disclosed. This reversing support mechanism is used for platform support and reversing of lifting and lowering movements of the intelligent construction platform, realizing movement conversion constraints during use. The reversing support mechanism includes a reversing box 1, which comprises two bottom plates 11 arranged vertically and two side plates 12 arranged side-by-side between the two bottom plates 11. A horizontally arranged first pin 2 connects the middle of the two side plates 12, and a gear 3 is connected to the first pin 2. The gear 3 is rotatably positioned between the two side plates 12. A horizontally arranged second pin 4 connects above the two side plates 12, and a stop 5 for limiting the rotation direction of the gear 3 is connected to the second pin 4. Each side plate 12 has two front and rear... The first insertion holes 123 are arranged side by side and located between the first pin 2 and the second pin 4. The two first insertion holes 123 on each side plate 12 are symmetrical about the center connection line of the first pin 2 and the second pin 4. The two first insertion holes 123 on the two side plates 12 are respectively matched and fitted. The first insertion hole 123 is adapted to a reversing shaft 6. After the reversing shaft 6 is inserted into different first insertion holes 123, the rotation direction of the gear 3 is restricted to either upward or downward. The rear side of each side plate 12 is connected to a snap-fit ​​plate 13 with a rectangular groove.

[0023] The reversing box 1 is used for the installation of various components and for connecting to the climbing guide rail 20 of the intelligent construction platform. The position adjustment of the reversing box 1 on the climbing guide rail 20 enables the lifting and lowering adjustment of the intelligent construction platform and provides support for it. The climbing guide rail 20 includes a limiting plate 201 for limiting the reversing box 1 and a step stop 202 for supporting the rotation of the gear 3. The reversing box 1 includes a base plate 11 and side plates 12, which form a frame structure for connecting to the climbing guide rail 20 and the platform supporting the construction platform. The side plates 12 are used for the installation of other components, including the first pin 2, the gear 3, the second pin 4, the stop block 5, and the reversing shaft 6. The first pin 2 is used to install and support the rotation of gear 3. The second pin 4 is used to install and support the rotation of stop 5. The reversing shaft 6 is used to limit the rotation direction and position of stop 5. Thus, by using stop 5 to control the rotation direction of gear 3, gear 3 can only rotate upwards or downwards. The upward or downward rotation of gear 3 drives the reversing support mechanism to move up or down along the climbing guide rail 20, thereby achieving the support of the intelligent construction platform and the reversing of its lifting motion. The snap-fit ​​plate 13 is used to snap into the limiting plate 201 of the climbing guide rail 20 to limit the reversing box 1 and prevent the reversing box 1 from separating from the climbing guide rail 20. The first insertion hole 123 is used for inserting the reversing shaft 6. By using different insertion holes for the reversing shaft 6, the direction of gear 3 is restricted. The snap-fit ​​plate 13 with a rectangular groove is used to engage with the limiting plate 201 of the climbing guide rail 20 to achieve lateral limiting and longitudinal movement guidance of the reversing box 1, ensuring that the reversing box 1 can only move up and down relative to the climbing guide rail 20.

[0024] like Figure 3 and Figure 4 As shown, when the reversing shaft 6 is inserted into the first insertion hole 123 on the front side, it can limit the forward rotation of the stop block 5, so that the stop block 5 can only rotate backward. At this time, correspondingly, the gear 3 can only rotate in the direction of rotation of the stop block 5. The upper end of the gear 3 can push the stop block 5 to rotate backward, that is, the gear 3 can rotate upward along the climbing guide rail 20 (counterclockwise when viewed from the left). Figure 5 and Figure 6 As shown, when the steering shaft 6 is inserted into the first insertion hole 123 on the rear side, it can limit the rearward rotation of the stop block 5, causing the stop block 5 to rotate forward. At this time, correspondingly, the gear 3 also rotates in the same direction as the rotation of the stop block 5. The upper end of the gear 3 can push the stop block 5 forward to rotate, that is, the gear 3 can rotate downward along the climbing guide rail 20 (clockwise rotation when viewed from the left). In other words, by inserting the reversing shaft 6 into the first insertion hole 123 at different positions, the rotation direction of the gear 3 can be reversed. By pushing the gear 3 to rotate, the reversing support mechanism can be driven to move up or down along the climbing guide rail 20, that is, the reversing of the lifting and lowering movement of the intelligent construction platform can be achieved.

[0025] When the reversing shaft 6 is inserted into the first insertion hole 123 located on the front side, the stop block 5 is restricted from rotating forward by the reversing shaft 6, which causes the gear 3 to be unable to rotate downward (it cannot rotate clockwise when viewed from the left). Under the action of gravity, the gear 3 engages with the step stop 202 on the guide rail 20, and the reversing support mechanism will not fall off the climbing guide rail 20, thus achieving the function of supporting the connected intelligent manufacturing platform.

[0026] In this application, the slots of two snap-fit ​​plates 13 are arranged opposite each other, and the upper and lower ends of the two snap-fit ​​plates 13 are respectively snapped onto the upper and lower base plates 11. A reinforcing plate 14 is snapped into the middle of each of the two snap-fit ​​plates 13. The oppositely arranged slots ensure that the connection position between the reversing box 1 and the climbing guide rail 20 is relatively fixed, ensuring the stability of the reversing box 1, thereby ensuring the stable support of the intelligent manufacturing platform. The snap-fit ​​of the upper and lower ends of the snap-fit ​​plates 13 with the base plates 11 ensures that the snap-fit ​​plates 13 are firmly fixed, thereby ensuring the structural strength of the reversing box 1; the reinforcing plate 14 can further enhance the installation firmness of the snap-fit ​​plates 13.

[0027] In the solution of this application, a first mounting hole 121 for mounting the first pin 2 is provided in the middle of each of the two side plates 12, and a second mounting hole 122 for mounting the second pin 4 is provided on the top of each of the two side plates 12. That is, the first pin 2 can be quickly installed through the first mounting hole 121, and the second pin 2 can be quickly installed through the second mounting hole 122. The structure is simple and easy to implement.

[0028] In one embodiment of this application, each of the two side plates 12 is provided with a second insertion hole 124. The second insertion hole 124 is located below the middle of the two first insertion holes 123 on the corresponding side plate 12 and above the first mounting hole 121. The distance between the second insertion hole 124 and the corresponding first mounting hole 121 is greater than the distance between the bottom of the tooth groove of the gear 3 and the first pin 2.

[0029] In this scheme, the second insertion hole 124 is used for the insertion of the pin. By setting the position of the second insertion hole 124, the second insertion hole 124 is positioned above the first pin 2, and the pin inserted into the second insertion hole 124 can be inserted into the tooth groove of the gear 3 when it rotates to the top, thus restricting the rotation of the gear 3, preventing the gear 3 from rotating up or down, achieving complete fixation of the gear 3, thereby completely fixing the reversing support mechanism on the climbing guide rail 20, and thus achieving platform support for the intelligent construction platform connected to the reversing support mechanism.

[0030] In another embodiment of this application, at least one of the two side plates 12 is provided with a proximity switch 9. The distance between the proximity switch 9 and the first pin 2 is greater than the distance between the bottom of the tooth groove of the gear 3 and the first pin 2, and the distance between the proximity switch 9 and the first pin 2 is less than the distance between the tooth tip of the gear 3 and the first pin 2. By setting the distance between the proximity switch 9 and the first pin 2, it is ensured that the proximity switch 9 can detect the number of teeth rotated by the gear 3. The distance moved by the reversing support mechanism relative to the climbing guide rail 20 can be accurately calculated by the number of teeth rotated by the gear 3, thereby realizing the lifting control of the intelligent construction platform.

[0031] In one embodiment of this application, a third mounting hole 125 and a fourth mounting hole 126 are respectively provided at the upper and lower ends of the two side plates 12. A third pin 7 is installed in the two corresponding third mounting holes 125 of the two side plates 12, and a fourth pin 8 is installed in the two corresponding fourth mounting holes 126 of the two side plates 12. The arrangement of the third mounting holes 125 and the third pin 7, and the fourth mounting holes 126 and the fourth pin 8, firstly strengthens the connection between the two side plates 12, thereby improving the structural strength of the overall reversing support mechanism. Simultaneously, the third pin 7 and the fourth pin 8 facilitate the connection of external structures, such as connecting rods or drive devices.

[0032] In one embodiment of this application, each of the two base plates 11 is provided with a through hole 111, and one of the upper and lower ends of the reversing box 1 is connected to a drive device, which includes a hydraulic cylinder.

[0033] In this solution, the structural design of the through hole 111 facilitates connection with the platform and drive device of the intelligent manufacturing platform. A connecting rod can be connected to the third pin 7 or the fourth pin 8 by passing through the through hole 111. For example, a connecting rod can be installed in the through hole 111 of the upper base plate 11 and connected to the third pin 7. The connecting rod of the drive device is connected through the through hole 111 of the lower base plate 11. The drive device pushes the reversing box 1 to move upward, thereby pushing the gear 3 to climb along the climbing guide rail 20.

[0034] Preferably, the drive device is a hydraulic cylinder, which can provide a large oil pressure to ensure that the entire intelligent construction platform can be lifted and lowered.
