[0022] The intelligent pier structure for bridge construction provided by the embodiment of the present invention has an automatic adjustment function and a better waterproof structure, which reduces the manpower operation at the bridge construction site; compared with traditional piers, the intelligent pier for bridge construction does not require manpower to adjust and can fine-tune the angle of the convex surface of the spherical crown through the automatic leveling mechanism on the spherical crown. It has a reliable waterproof sealing mechanism and a lubrication function, is more capable of coping with the harsh working conditions of bridge construction, is stable, reliable, easy to use, and has a higher safety factor.

[0023] Figure 1 is a schematic diagram of the overall structure of an intelligent shelf according to an embodiment of the present invention. Figure 2 is a cross-sectional view of an intelligent shelf according to an embodiment of the present invention, Figure 1 and Figure 2 As shown, the pier comprises: a rotating screw barrel 1, an outer barrel 2, an inner barrel 3, a ball cap assembly 4, a driven gear 5, a driving gear 61 and a first motor reduction unit 62; the rotating screw barrel 1 is arranged above the outer barrel 2, and the lower end surface of the rotating screw barrel 1 contacts the upper end surface of the outer barrel 2; the inner barrel 3 is arranged inside the rotating screw barrel 1 and the outer barrel 2, and the trapezoidal thread of the outer wall of the inner barrel 3 and the trapezoidal thread of the inner wall of the rotating screw barrel 1 form a transmission pair; The ball crown assembly 4 is fixedly arranged on the upper end surface of the inner cylinder 3 and moves up and down with the inner cylinder 3; the driven gear 5 is sleeved at the junction of the rotating screw cylinder 1 and the outer cylinder 2 and is fixedly connected to the outer peripheral surface of the rotating screw cylinder 1; the motor reducer unit is welded to the outer wall of the outer cylinder 2 through the motor bracket 621, the driving gear 61 is connected to the output shaft 622 of the first motor reducer unit 62, and the top of the driving gear 61 cooperates with the output shaft 622 through screws and gaskets to limit the driving gear 61, and the driving gear 61 is meshed with the driven gear 5.

[0024] Specifically, the first motor reduction unit 62 is fixed to the motor bracket 621 by bolts and nuts, and the motor bracket 621 is welded and fixed to the outer wall of the outer cylinder 2. The driving gear 61 on the output shaft 622 at one end of the first motor reduction unit 62 rotates to drive the driven gear 5 to rotate. The driven gear 5 is welded and fixed to the lower part of the rotating screw barrel 1 and a portion of it is exposed and covered on the outer wall of the outer cylinder 2. The trapezoidal thread on the inner wall of the rotating screw barrel 1 is rotated and transmitted to the trapezoidal thread on the outer wall of the inner cylinder 3, thereby converting it into a vertical up and down movement of the inner cylinder 3, and the ball crown assembly 4 moves vertically up and down therewith.

[0025] The present embodiment eliminates the manual operation of the traditional pier, and divides the traditional outer cylinder 2 into two parts, the outer cylinder 2 and the rotating screw cylinder 1. The first motor reduction unit 62 installed on the motor bracket 621 drives the driving gear 61 to rotate, and the driving gear 61 rotates to drive the driven gear 5 to rotate. The driven gear 5 is fixed to the rotating screw cylinder 1 and drives the rotating screw cylinder 1 to rotate together. The rotating screw cylinder 1 drives the outer trapezoidal thread of the inner cylinder 3 through the internal trapezoidal thread, thereby automatically driving the ball crown assembly 4 to move up and down, avoiding the risk of manual up and down movement.

[0026] Figure 3 Schematic diagram of the assembly of the ball cap assembly according to an embodiment of the present invention. Figure 3 As shown, in some embodiments, the spherical crown assembly 4 includes: a spherical crown concave surface 41 and a spherical crown convex surface 42; the lower end of the spherical crown concave surface 41 is welded to the upper end surface of the inner tube 3 to form a whole; the spherical crown convex surface 42 is arranged on the upper part of the spherical crown concave surface 41, and is connected to the spherical crown concave surface 41 by screws, and the spherical crown convex surface 42 deflects on the spherical crown concave surface 41 within a preset deflection angle range to adjust the top surface of the spherical crown convex surface 42 to be in a horizontal state.

[0027] like Figure 2 As shown, in some embodiments, the spherical cap assembly 4 further includes an automatic leveling mechanism, which includes a second motor reducer unit 43 and an inclination sensor 44; the second motor reducer unit 43 is built in the lower end of the spherical cap concave surface 41 and connected to a lever 45 located at the center of the spherical cap convex surface 42; the second motor reducer unit 43 drives the lever 45 to adjust the deflection angle of the spherical cap convex surface 42 on the spherical cap concave surface 41; the inclination sensor 44 is installed on the side of the spherical cap convex surface 42, and is used to monitor the inclination angle of the top of the pier in real time. The lever 45 automatically adjusts the inclination angle of the spherical cap to adapt to the bottom of the beam under the combined action of the built-in second motor reducer unit 43 and the inclination sensor 44.

[0028] In this embodiment, the convex surface 42 of the spherical crown can be braked and leveled at the top of the convex surface by an automatic leveling mechanism, that is, a small motor and a second reduction gear unit inside drive the lever 45 located at the center of the convex surface 42 of the spherical crown to adjust the angle, thereby realizing the movement of the convex surface 42 of the spherical crown. At the same time, the inclination sensor 44 on the convex surface 42 of the spherical crown monitors the inclination of the top of the pier in real time, and the automatic leveling mechanism automatically controls the leveling angle of the convex surface 42 of the spherical crown through the inclination data fed back by the inclination sensor 44, that is, when the bracket or the bottom of the beam is slightly tilted due to external factors, the angle of the convex surface 42 of the spherical crown can be automatically adjusted through the monitoring feedback data to ensure that the pier and the bottom of the beam maintain the best contact. When the horizontal level is reached, the control system stops the action after giving an instruction, and no human adjustment is required.

[0029] like Figure 2As shown, in some embodiments, the pier further includes a displacement measurement assembly, which includes: a connecting plate 71, a displacement bracket 72 and a displacement sensor 73; the connecting plate 71 is fixed to the lower end surface of the inner tube 3, the displacement sensor 73 is fixed to the inner side wall of the outer tube 2 through the displacement bracket 72, and one end of the pull rope on the displacement sensor 73 is fixed to the threaded hole 711 of the connecting plate 71 and is threadedly connected to the connecting plate 71. The pull rope is a part of the displacement sensor 73, and the distance of the inner tube 3 moving up and down is monitored by the length of the extension or contraction of the pull rope. The top of the pull rope has an external thread, and the bottom of the inner tube 3 has an internal thread, and the two are connected by threads.

[0030] Specifically, the displacement sensor 73 is fixed to the inner wall of the outer cylinder 2 through the displacement bracket 72, the pull rope of the displacement sensor 73 is threadedly connected to the connecting plate 71, and the end of the connecting plate 71 is fixedly welded to the bottom of the inner cylinder 3, so that the inner cylinder 3 moves vertically up and down inside the outer cylinder 2. During the up and down movement of the inner cylinder 3, the pull rope will vertically extend or shorten, so as to monitor the vertical up and down distance of the inner cylinder 3 in real time, and the vertical up and down distance of the inner cylinder 3 can be measured, and the signal is transmitted to the controller. The controller compares the vertical up and down distance of the inner cylinder 3 with the preset target displacement value, and automatically stops when the displacement reaches the set target displacement value, and automatically rises and falls when it is lower than or exceeds the set target displacement value.

[0031] In this embodiment, the displacement sensor 73 can be used to monitor the distance of the inner cylinder 3 moving up and down in real time, so that when the inner cylinder 3 reaches the specified displacement set by the controller, the controller program automatically controls the start and stop of the motor of the first motor reducer unit 62, thereby ensuring the automatic control operation of the intelligent pier without the need for human adjustment; in addition, in actual work, if the displacement sensor 73 monitors the movement of the inner cylinder 3 to a specified position, the system will control the first motor reducer unit 62 to stop rotating, thereby ensuring that the distance of the pier moving up and down under any working condition is within the set range.

[0032] like Figure 2 As shown, in some embodiments, the pier further includes a guide assembly, which includes a guide groove plate 81 and a guide block 82: one end of the guide block 82 is fixedly welded to the inner wall of the outer cylinder 2, and one end of the guide groove plate 81 is fixed to the inner wall of the inner cylinder 3, and the guide groove plate 81 moves up and down along the guide block 82. Specifically, the upper end of the guide groove plate 81 is fixed to the inner cylinder 3, and the guide block 82 is a rectangular parallelepiped, and its lower end surface is fixed to the wall of the outer cylinder 2. In this embodiment, the guide groove plate 81 is fixed to the inner wall of the inner cylinder 3, and moves up and down along the guide block 82 fixed to the inner wall of the outer cylinder 2, so that the inner cylinder 3 moves vertically up and down during the threaded transmission, which can prevent the inner cylinder 3 from deflecting. In addition, the outer cylinder 2 in this embodiment is both a load-bearing structure and also plays a guiding role.

[0033] like Figure 2 As shown, in some embodiments, the pier further includes a waterproof mechanism 9, which is embedded in the inner side surface of the driven gear 5, is located below the rotating contact surface between the lower end surface of the rotating screw cylinder 1 and the upper end surface of the outer cylinder 2, and contacts the outer side wall of the outer cylinder 2. This makes the pier of the embodiment of the present invention have a reliable waterproof function and a lubricating effect.

[0034] Figure 4 Schematic diagram of a waterproof mechanism according to an embodiment of the present invention. Figure 4 As shown, in some embodiments, the waterproof mechanism 9 includes: a plurality of slide posts 91, a spring 92 and a graphite ring 93; the plurality of slide posts 91 are embedded in the inner side surface of the driven gear 5 at intervals along the circumference of the driven gear 5, the graphite ring 93 is sleeved on the outer side wall of the outer tube 2, and is embedded in the first groove 911 of each slide post 91, and the portion of the graphite ring 93 exposed from the first groove 911 is in contact with the outer side wall of the outer tube 2; the spring 92 is arranged in the second groove 912 of each slide post 91, and is used to support the slide post 91.

[0035] Specifically, a waterproof mechanism 9 is designed inside the exposed section of the lower part of the driven gear 5. The waterproof mechanism 9 includes a spring 92, a slide post 91 and a graphite ring 93. The graphite ring 93 is embedded in the first groove 911 of the slide post 91 and a section is exposed to be in close contact with the outer wall of the outer cylinder 2. The spring 92 presses the slide post 91 so that the graphite ring 93 is in close contact with the outer cylinder 2 to prevent water from entering the cylinder cavity through the gap of the outer cylinder 2. The spring 92 is set in the second groove of the slide post 91, and the second groove is close to one side of the driven gear 5. One end of the spring 92 is in contact with the inner side of the driven gear 5, and the other end is against the slide post 91, so that the slide post 91 can clamp the graphite ring 93.

[0036] In this embodiment, since the graphite ring 93 has an excellent lubricating effect, it can prevent the driven gear 5 from generating a large friction force by friction at the contact part with the outer cylinder 2. In addition, it should be noted that the reason why the graphite ring 93 is exposed for a part when it is embedded in the first groove 911 of the sliding column 91 in this embodiment is that since the graphite ring 93 of this embodiment rotates with the driven gear 5, friction will be generated at the contact part with the wall of the outer cylinder 2, and there will be wear over time, so the thickness of the graphite ring 93 of this embodiment is greater than the depth of the first groove, so that the graphite ring 93 will extend out of a part of the first groove. In the case that the graphite ring 93 is worn, the spring 92 will continue to press it tightly to make it close to the outer wall of the outer cylinder 2 without generating a gap, so that the graphite ring 93 always maintains close contact with the outer cylinder 2.

[0037] like Figure 4 As shown, in some embodiments, a plurality of slide posts 91 are evenly arranged on the inner side of the driven gear 5 , and an O-ring 94 is sleeved on the outer side of each slide post 91 to prevent water from entering the inner cavity of the inner cylinder 3 through the gap of the slide post 91 .

[0038] Specifically, if the graphite ring 93 is not in close contact with the outer wall of the outer cylinder 2, water can enter the inner cavity of the cylinder through the gap, so in this embodiment, a plurality of slide posts 91 are evenly distributed on the inner circumference of the driven gear 5, so that the force of the graphite ring 93 is balanced, and then all parts of the entire graphite ring 93 are in close contact with the outer wall of the outer cylinder 2, thereby improving the waterproof effect. The waterproof mechanism 9 of this embodiment not only has a self-sealing function, but also has a lubricating function.

[0039] Figure 5 is a side view of an intelligent shelf according to an embodiment of the present invention, Figure 5 As shown, in some embodiments, the shelf also includes a butter cup, which is arranged on the outer wall of the rotating barrel 1 and connected to a butter hole 11 on the wall of the rotating barrel 1, and the butter hole 11 passes through the upper end surface of the outer barrel 2; the butter in the butter cup is injected into the rotating contact surface between the lower end surface of the rotating barrel 1 and the upper end surface of the outer barrel 2 through the butter hole 11.

[0040] In this embodiment, grease is applied to the portion where the lower end surface of the rotating cylinder 1 contacts the plane of the upper end of the outer cylinder 2 to maintain lubrication, thereby reducing the friction between the rotating cylinder 1 and the upper end surface of the outer cylinder 2 during the process of rotating under force.

[0041] like Figure 5 As shown, in some embodiments, a rain cover 63 is provided above the driving gear 61 to prevent rain and protect the driving gear 61 and the first motor reduction unit 62; the rain cover 63 is fixed to the motor bracket 621 by screws; a drainage hole is opened at the end of the contact surface between the motor bracket 621 and the outer cylinder 2, so that rainwater can flow directly to the ground along the hole to prevent water accumulation. In this embodiment, the position of the drainage hole can be adjusted, for example, it can be a small hole opened on the motor bracket 621 to prevent water accumulation.

[0042] The intelligent shelf of the embodiment of the present invention has the following beneficial effects: The intelligent pier controls the motor reduction unit to rotate through a control system, the driving gear 61 drives the driven gear 5 to rotate, the driven gear 5 drives the rotating screw barrel 1 to rotate, and the rotating screw barrel 1 drives the inner barrel 3 to automatically move vertically up and down in the outer barrel 2 without human intervention.

[0043] Grease is applied between the rotating surfaces where the lower end surface of the rotating screw barrel 1 contacts the upper end surface of the outer barrel 2 to maintain lubrication, thereby reducing the friction of the rotating screw barrel 1 during the process of rotating under force.

[0044] The embodiment of the present invention can prevent the inner cylinder 3 from deflecting during the rotation process by providing a guide assembly.

[0045] The displacement sensor 73 monitors the distance of the inner tube 3 moving up and down in real time. When the displacement sensor 73 monitors that the movement of the inner tube 3 is in place, the controller will control the motor reduction unit to stop rotating, thereby ensuring that the distance of the pier moving up and down under any working condition is within the set range.

[0046] Compared with traditional types of piers, the piers in the embodiment of the present invention do not require manpower to adjust, and can fine-tune the angle of the spherical crown convex surface 42 through the leveling mechanism on the spherical crown assembly 4. At the same time, it has a reliable waterproof sealing mechanism and a lubrication function, which is more capable of coping with the harsh working conditions of bridge construction, and is stable, reliable, easy to use, and has a higher safety factor.

[0047] The intelligent shelf of the embodiment of the present invention has the following beneficial effects: The embodiment of the present invention realizes automatic lifting of the pier through a motor reduction unit and a gear transmission system without manual operation, thereby improving construction efficiency and reducing manual labor and safety risks.

[0048] The automatic leveling mechanism provided on the spherical crown assembly in the embodiment of the present invention can adjust the deflection angle of the convex surface of the spherical crown in real time to ensure that the top is in a horizontal state, and can be automatically adjusted even when the bottom of the beam or the bracket is slightly tilted.

[0049] The embodiment of the present invention can monitor the up and down movement of the inner tube in real time through the displacement sensor, automatically control the pier to reach the set height, and ensure accurate positioning.

[0050] The embodiment of the present invention prevents water from entering the barrel by providing a waterproof mechanism, and has a lubricating effect, so as to adapt to a more severe construction environment.

[0051] The embodiment of the present invention reduces the friction between the rotating screw barrel and the outer barrel by providing a grease cup and lubrication, thereby protecting the device and extending its service life.

[0052] The embodiment of the present invention prevents the inner cylinder from deflecting during the rotation process by arranging a guide assembly, thereby maintaining the stable operation of the device.

[0053] The entire system of the embodiment of the present invention does not require manual operation, thereby reducing potential safety hazards caused by manual operation and improving the overall safety factor of bridge construction.

[0054] The embodiment of the present invention is equipped with a rain cover and a water drop hole design to prevent water accumulation from affecting the operation of the device, so that the device remains stable and reliable under changing environmental conditions.
