Description

Technical Field

[0001] The utility model relates to the technical field of pipe pile production, in particular to an inflatable rubber plug inflatable clamping device. Background Art

[0002] Prestressed pipe piles are mainly used for low-bearing pile foundations of industrial and civil buildings, and are widely used in the foundations of railways, highways and bridges, municipal and large-scale equipment projects. They have high strength, strong bearing capacity, and strong adaptability to geological structures. The general method of making reinforced concrete prestressed pipe piles is: the steel cage is placed in a mold, concrete is poured into the mold, and then centrifugal molding is performed.

[0003] Existing pipe pile molds consist of an upper mold and a lower mold, fixed together by bolts to form a cylindrical structure. Head and tail plates are installed at the front and rear ends of the mold, sealing the longitudinal openings of the cylindrical structure. Holes are located in the center of the head and tail plates. During concrete placement, a pump tube is inserted through the hole in the tail plate to pump concrete in. After the pump tube is removed, a rubber plug is inserted into the hole in the tail plate to prevent concrete from leaking out.

[0004] The diameter of the existing rubber plug is larger than the center hole of the tail plate, creating an interference fit with the center hole of the tube mold tail plate. Existing automatic rubber plugging equipment uses a powerful hydraulic system to force the plug into the hole of the tube mold tail plate. This equipment is bulky and complex, occupies a large space, consumes a lot of energy, and suffers from severe wear and tear on the plug, resulting in a short service life. Utility Model Content

[0036] Please refer to Figure 1 and Figure 2This embodiment provides an inflatable plug inflatable clamping device, including a moving device, a clamping device 100, an inflating device 200 and an inflatable plug device 300.

[0037] The inflatable plug device 300 includes a center tube 310, a flange ring 320, and an airbag 330. The airbag 330 is disposed around the periphery of the flange ring 320 to form a sealed chamber 301. The center tube 310 is connected to the flange ring 320, and the inner cavity of the center tube 310 is connected to the sealed chamber 301. The airbag 330 has an inflated state and a deflated state. In the deflated state, the outer diameter of the airbag 330 is smaller than the diameter of the center hole of the tail plate of the tube mold. In the inflated state, the outer diameter of the airbag 330, after expanding along the circumference of the flange ring 320, is greater than or equal to the diameter of the center hole.

[0038] The clamping device 100 is connected to the central tube 310 to clamp or release the central tube 310;

[0039] The inflation device 200 is connected to the central tube 310 to inflate the airbag 330;

[0040] The moving device can be connected to the clamping device 100 to drive the clamping device 100 to move toward the tail plate until the air bag 330 is inserted into the central hole, or to drive the air bag 330 to be separated from the central hole.

[0041] The inflatable rubber plug inflation and clamping device of this embodiment includes a moving device, a clamping device 100, an inflation device 200, and an inflatable rubber plug device 300. The inflation device 200 inflates the inflatable rubber plug device 300, thereby causing the airbag 330 to expand and seal the center hole, preventing slurry leakage in the precast column mold. The clamping device ensures the stability of the airbag 330 during inflation and sealing of the center hole. The moving device drives the entire device to position the airbag 330 into the hole in the tail plate of the mold. The airbag 330 is then inflated via a solenoid valve, causing it to expand and seal the center hole of the coaming. Furthermore, when deflated, the outer diameter of the airbag 330 is smaller than the diameter of the center hole of the tail plate of the tube mold. When inflated, the outer diameter of the airbag 330, after expanding circumferentially along the flange ring 320, is greater than or equal to the diameter of the center hole. This ensures that the airbag 330 can be easily inserted into and removed from the center hole while also ensuring that the airbag 330 stably blocks the center hole. In summary, this inflatable rubber plug inflation and clamping device has a simple structure, is easy to operate, requires minimal space, consumes little energy, is reusable, and has a long product life.

[0042] Please continue reading Figure 1 and Figure 2, to understand the structural details of the inflatable rubber plug inflation clamping device. Optionally, the center tube 310 is a cylindrical pipe. The center tube 310 adopts a seamless tube, one end of which is sealed, and the other end is left with an inflation nozzle 340 for installation, and a vent hole 311 is opened in the center of the center tube 310. The vent hole 311 is located in the sealed chamber 301. The flange ring 320 includes two flange discs 322 arranged in parallel, and the two flange discs 322 are formed and sized the same and maintained in a concentric arrangement. The annular airbag 330 is sealed on the circumferential opening of the flange ring 320.

[0043] Optionally, the moving device is a robot or other multi-axis motion mechanism.

[0044] In an optional embodiment, the inflatable plug inflatable clamping device further includes a flexible flange 11; along the length direction of the flexible flange 11, one end of the flexible flange 11 can be connected to the clamping device 100, and the other end can be connected to the moving device.

[0045] The flexible flange 11 provides both support and flexibility. This allows the flexible flange 11 to adapt to any deviation between the center of the inflatable plug device 300 and the center hole of the tube mold tail plate through deformation, thereby allowing the airbag 330 to be more easily inserted into and removed from the tail plate center hole. Optionally, the flexible flange 11 comprises a rubber tube and two flanges disposed at either end of the tube's length. It will be appreciated that in other embodiments of the present invention, the flexible flange 11 may also be made of other elastic materials or a spring mechanism.

The fixing base 12 provides a mounting and connection platform for the mobile device, and the end of the inflatable device 200 remote from the inflatable plug device 300 is also disposed on the fixing base 12, thereby facilitating the reliability and stability of the inflatable device 200 as a whole.

[0047] Optionally, the fixing seat 12 and the end flange of the flexible flange 11 are detachably connected via connecting screws 15 .

[0048] In an optional embodiment, the inflatable plug inflatable clamping device further includes a fixed flange 13; the fixed flange 13 is connected to the end of the flexible flange 11 near the inflatable plug device 300; the clamping jaw device 100 is disposed on the side of the fixed flange 13 facing away from the flexible flange 11; the inflatable device 200 is disposed in the flexible flange 11, and the end of the inflatable device 200 near the inflatable plug device 300 is disposed on the fixed flange 13. The fixed flange 13 here serves as a transitional mounting component between the flexible flange 11, the inflatable device 200, and the clamping jaw device 100, and can ensure the stability and reliability of the overall structure.

[0049] In an optional embodiment, the central axis of the flexible flange 11 is parallel to or coincides with the central axis of the central tube 310. This facilitates the timely and efficient mating of the inflatable plug device 300 with the central hole of the tail plate.

[0050] In an alternative embodiment, the inflation device 200 includes an inflation head 210 and a hose 220. Along its length, the inflation head 210 can be connected to the central tube 310 at one end and to the hose 220 at the other end. The hose 220 is configured to connect to an air source. The hose 220 is positioned within the flexible flange 11, adapting to the deformation of the flexible flange 11 and ensuring a continuous and reliable airflow supply to the central tube 310.

[0051] As can also be seen from the figure, in an optional embodiment, a control valve 14 is provided on the hose 220 to disconnect or connect the fluid in the hose 220. The control valve 14 controls the flow of air in the hose 220. The optional control valve 14 is mounted on the fixing base 12 and is a solenoid valve.

[0052] Furthermore, in an optional embodiment, the end of the central tube 310 is provided with an inflation nozzle 340, which is connected to the inner cavity of the central tube 310. The end of the inflation head 210 has a trumpet-shaped guide opening 211, and the inflation nozzle 340 is snap-fitted to the guide opening 211 to communicate with the hose 220. It should be noted that the inflation device 200 can automatically dock with the inflation nozzle 340 of the inflation plug device 300 for inflation.

[0053] In an alternative embodiment, the clamping device 100 includes an upper clamping block, a lower clamping block, and a drive mechanism 110; the upper clamping block and the lower clamping block are arranged opposite each other; the drive mechanism 110 is respectively coupled with the upper clamping block and the lower clamping block to drive the upper clamping block and the lower clamping block toward each other to clamp the central tube 310, or to drive the upper clamping block and the lower clamping block away from each other to release the central tube 310. Optionally, the drive mechanism 110 is a pneumatic cylinder structure.

[0054] In an optional embodiment, both the upper clamping block and the lower clamping block have a V-shaped groove to form a V-shaped clamping block, and the openings of the V-shaped grooves of the upper clamping block and the lower clamping block are both facing the central tube 310 .

[0055] Working principle of inflatable rubber plug inflatable clamping equipment:

[0056] The fixing base 12 is connected to the robot, and the fixing base 12 is connected to the fixing flange 13 through a flange flexible connection. The pneumatic gripper device 100 and the inflating device 200 are both connected to the fixing flange 13;

[0057] After the inflation nozzle 340 of the inflation plug device 300 is docked with the inflation head 210 through the inflation system guide port 211, the pneumatic clamping device 100 clamps the central tube 310 firmly.

[0058] The robot then drives the entire mechanism to place the airbag 330 into the hole of the tail plate of the tube mold, and inflates the plug through the solenoid valve to expand the airbag 330 to seal the central hole of the tail plate of the tube mold; then the pneumatic clamping device 100 releases the inflatable plug device 300, and the inflatable plug device 300 can be transferred together with the entire tube mold, thereby facilitating the subsequent prefabricated column forming.

[0059] In summary, the embodiments of the present invention provide an inflatable rubber plug inflatable clamping device, which has at least the following advantages:

[0060] The flexible flange 11 has a certain degree of support and elasticity. Even if there is some deviation between the center of the rubber plug and the center of the tail plate hole of the pipe mold, the deformation of the flexible flange can adapt to it.

[0061] The inflation device 200 can automatically connect with the rubber plug for inflation.

[0062] The airbag 330 can be easily inserted into or removed from the center hole, and can also ensure that the airbag 330 stably blocks the center hole. In summary, the inflatable rubber plug inflation clamping device has the advantages of simple structure, easy operation, small space, low energy consumption, reusability, and long product life.
