Description

Technical Field

[0001] This utility model relates to the field of pneumatic gate technology, and in particular to a pneumatic gate that is easy to install and remove the baffle. Background Technology

[0002] A pneumatic gate is a device that uses air pressure to control the opening and closing of a valve. Its working principle is to provide compressed air to the pneumatic actuator through an air supply system, and drive the valve to open and close through pressure changes. In terms of structural principle, a pneumatic gate usually adopts a combination of piston and gate. The air pressure pushes the piston to drive the gate to make a displacement perpendicular to the fluid, thereby realizing the opening and closing of the valve.

[0003] The gate baffle of the pneumatic gate is connected to the cylinder by a fastening screw. When the gate baffle is repaired or disassembled, it needs to be lifted to the top and detached from the top. However, the operating space at the top is limited, making it impossible to quickly detach the gate baffle. This increases the difficulty of disassembling and assembling the gate baffle. Based on the above description of the defects of the prior art, we propose a pneumatic gate that facilitates the disassembly and assembly of the baffle to solve this defect of the prior art. Utility Model Content

[0004] The purpose of this utility model is to provide a pneumatic gate that facilitates the disassembly and assembly of the baffle, thus having the effect of facilitating the disassembly and assembly of the baffle.

[0005] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a pneumatic gate that is easy to assemble and disassemble, comprising a gate frame, a limiting crossbar horizontally installed on the surface of the gate frame, a top rod, a cylinder installed on the surface of the top rod, and a gate baffle installed at the cylinder push rod.

[0006] At least one sealed sliding groove is provided on both sides of the surface of the gate frame, and a piston rod is slidably sealed in the sealed sliding groove. The piston rod is connected to the top rod.

[0007] The gate frame is equipped with a high-pressure air pump, which is located above the limiting crossbar. The air pump has a connector at its inflation port, which is connected to the sealed sliding grooves on both sides.

[0008] By adopting the above technical solution, gas is injected into the sealed slide groove through the working connection of the high-pressure air pump. By utilizing the sealed sliding of the piston rod and the sealed slide groove, when the cylinder is in the fully contracted state, the air pressure pushes the piston rod to the top, which simultaneously drives the top rod, the cylinder and the gate baffle to move upwards. This ensures that the gate baffle is disengaged and located above the limit crossbar, thus creating a space for disassembly and assembly of the gate baffle, making it convenient for the gate baffle to be disassembled and detached from the cylinder.

[0009] A further feature of this invention is that the gate baffle passes through the limiting crossbar and is tightly fitted to the limiting crossbar and the gate frame.

[0010] By adopting the above technical solution, the opening and closing sealing effect of the gate baffle is guaranteed.

[0011] A further feature of this invention is that the left and right side walls of the inner cavity of the gate frame are provided with a plurality of guide wheels that contact the front and rear surfaces of the gate baffle.

[0012] By adopting the above technical solution, the guide wheel rolls to guide the gate, preventing the gate baffle from moving and shifting.

[0013] A further feature of this invention is that the connector includes an inflation pipe connected to the inflation port of the high-pressure air pump and a connecting pipe connected between the inflation pipe and the sealed sliding grooves on both sides.

[0014] The connection point between the connecting pipe and the sealed slide groove is located below the piston rod.

[0015] By adopting the above technical solution, the gas charged by the high-pressure air pump can be discharged into the sealed slide through the connecting parts.

[0016] A further feature of this invention is that: a pair of fixing seats that contact the surface of the top rod are provided on the upper surfaces of the left and right sides of the gate frame, and locking holes that communicate with each other are provided between the fixing seats and the top rod, and locking screws are inserted into the locking holes.

[0017] By adopting the above technical solution, the fixing seat and the top rod are locked and fixed by tightening the locking screw, thus preventing the top rod from loosening.

[0018] A further feature of this invention is that: the surface of the limiting crossbar is provided with a mounting plate, a threaded adjusting rod is threadedly connected to the mounting plate, one end of the threaded adjusting rod is provided with a movable seat, the other end of the movable seat is provided with a U-shaped seat, and the surface of the U-shaped seat is provided with at least one guide rod passing through the mounting plate.

[0019] By adopting the above technical solution, the U-shaped seat is pushed to the bottom of the gate baffle by rotating the adjusting screw rod under the limiting action of the guide rod, thus supporting the gate baffle.

[0020] A further feature of this invention is that the piston rod and the sealed slide groove are not separated, and when the piston rod is at its uppermost position, the lower surface of the gate baffle is located above the limiting crossbar.

[0021] By adopting the above technical solution, it is ensured that when the gate baffle moves to the top, the gate baffle and the limit bar are in a separated state.

[0022] A further feature of this invention is that the U-shaped seat is located outside the gate baffle, and when the threaded adjusting rod is in the fully screwed-in state, the opening of the U-shaped seat is located directly below the gate baffle.

[0023] By adopting the above technical solution, the U-shaped seat can be aligned and support the gate baffle when it is moved to the top.

[0024] A further feature of this invention is that when the piston rod is at its highest position, the gate baffle separates from the guide wheel.

[0025] By adopting the above technical solution, the guide wheel is prevented from blocking the gate baffle when it moves to the top, thus preventing the gate baffle from detaching.

[0026] A further feature of this invention is that the rectangular surface formed by the combination of the gate frame and the limiting crossbar is provided with a plurality of mounting holes that are equally spaced in a rectangular shape.

[0027] By adopting the above technical solution, it is convenient to connect and fix the conveying pipeline to the gate frame through the mounting holes using screws.

[0028] The beneficial effects of this utility model are as follows: When disassembling and assembling the gate baffle, gas is injected into the sealed sliding groove through the working connection of the high-pressure air pump. By utilizing the sealed sliding of the piston rod and the sealed sliding groove, when the cylinder is in the fully contracted state, the air pressure pushes the piston rod to the top, which simultaneously drives the top rod, the cylinder and the gate baffle to move upwards, ensuring that the gate baffle is detached and located above the limit crossbar, thereby creating a space for disassembly and assembly of the gate baffle, making it convenient for the gate baffle to be disassembled and detached from the cylinder.

[0035] The technical solution of this utility model will now be clearly and completely described with reference to specific embodiments. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0036] Please see Figure 1-4 This utility model provides a pneumatic gate that is easy to assemble and disassemble, including a gate frame 1, a limiting crossbar 2 horizontally installed and fixed between the inner surfaces of the two sides of the gate frame 1, a top rod 3, a cylinder 4 fixed to the upper surface of the top rod 3 by fastening screws, and a gate baffle 5 fixed to the push rod of the cylinder 4 by fastening screws. The gate baffle 5 passes through the limiting crossbar 2 and is tightly fitted to the limiting crossbar 2 and the gate frame 1. The left and right side walls of the inner cavity of the gate frame 1 are rotatably connected to multiple guide wheels 6 that contact the front and rear surfaces of the gate baffle 5.

[0037] The guide wheel 6 is made of rubber to ensure that it rolls in contact with the gate baffle 5, thereby reducing wear on the gate baffle 5.

[0038] When the cylinder 4 operates, it drives the gate baffle 5 to move under the rotation limit and guidance of the guide wheel 6, thereby achieving opening and closing.

[0039] The rectangular surface formed by the combination of the gate frame 1 and the limiting crossbar 2 has multiple mounting holes distributed at equal intervals in a rectangular shape. When the conveying pipeline is connected to the gate frame 1, the conveying pipeline can be installed, connected and fixed on the gate frame 1 by passing the fastening screws through the fixing holes and mounting holes of the conveying pipeline.

[0040] A pair of fixing seats 12 that are in contact with the surface of the top rod 3 are installed and fixed on the upper surface of the left and right sides of the gate frame 1. The fixing seats 12 and the top rod 3 are provided with locking holes that are interconnected, and locking screws 13 are inserted into the locking holes.

[0041] By tightening the locking screw 13, the fixed seat 12 and the top rod 3 are locked in place, preventing the top rod 3 from loosening.

[0042] The gate frame 1 has at least one sealed sliding groove 7 on each side of its upper surface. A piston rod 8 slides in the sealed sliding groove 7 and is connected and fixed to the top rod 3.

[0043] A high-pressure air pump 9 is fixedly mounted on the surface of the gate frame 1 by fastening screws. The high-pressure air pump 9 is located above the limiting crossbar 2. A connector is provided at the air inlet of the high-pressure air pump 9. The connector communicates with the sealed sliding grooves 7 on both sides. The connector includes an air inlet pipe 10 connected to the air inlet of the high-pressure air pump 9 and a connecting pipe 11 connected between the air inlet pipe 10 and the sealed sliding grooves 7 on both sides. The connection between the connecting pipe 11 and the sealed sliding groove 7 is located below the piston rod 8.

[0044] The piston rod 8 and the sealed slide 7 are not separated. When the piston rod 8 is at the top, the lower surface of the gate baffle 5 is above the limiting crossbar 2. When the piston rod 8 is at the top, the gate baffle 5 is separated from the guide wheel 6.

[0045] When it is necessary to disassemble or assemble the gate baffle 5, firstly, start the cylinder 4 to move the gate baffle 5 to the top. After loosening the locking screw 13 to separate it from the fixed seat 12 and the top rod 3, the high-pressure air pump 9 works in conjunction with the interconnection between the air filling pipe 10, the connecting pipe 11 and the sealed slide groove 7 to fill the sealed slide groove 7 with gas. By using the piston rod 8 to slide in the sealed slide groove 7, when the cylinder 4 is in the fully contracted state, the air pressure pushes the piston rod 8 to the top, which simultaneously drives the top rod 3, the cylinder 4 and the gate baffle 5 to move upwards. This ensures that the gate baffle 5 is disengaged from the guide wheel 6 and located above the limit crossbar 2, thus creating space for disassembly and assembly of the gate baffle 5, making it convenient for the gate baffle 5 to be disassembled and detached from the cylinder 4.

[0046] It should be added that the connecting pipe 11 is equipped with an exhaust valve. Opening the exhaust valve will release the gas in the sealed slide groove 7, the piston rod 8 will move down to reset, and the locking screw 13 will be tightened. This will allow the gate baffle 5 to be reset and fixed after disassembly and replacement.

[0047] The front surface of the limiting crossbar 2 is fixed with a mounting plate 14 by fastening screws. A threaded adjusting rod 15 is threadedly connected to the mounting plate 14. The mounting plate 14 has a threaded hole that matches the thread of the threaded adjusting rod 15. One end of the threaded adjusting rod 15 has a movable seat 18 that rotates circumferentially. The other end of the movable seat 18 is fixed with a U-shaped seat 16. At least one guide rod 17 that passes through the mounting plate 14 is fixed on the surface of the U-shaped seat 16. The guide rod 17 is inseparable from the mounting plate 14. The U-shaped seat 16 is located outside the gate baffle 5. When the threaded adjusting rod 15 is in the fully screwed-in state, the opening of the U-shaped seat 16 is located directly below the gate baffle 5.

[0048] Furthermore, when the high-pressure air pump 9 is working and filling with air, after the gate baffle 5 moves to the top, rotating the threaded adjusting rod 15 utilizes the threaded connection between the threaded adjusting rod 15 and the mounting plate 14, as well as the linear extension and retraction limit of the guide rod 17 on the U-shaped seat 16, to push the U-shaped seat 16 to move below the gate baffle 5 when the threaded adjusting rod 15 rotates. This allows the cylinder 4 to push the gate baffle 5 to sit on the U-shaped seat 16, thus supporting the gate baffle 5 and facilitating its removal from the cylinder 4 under the support.
