Description

Technical Field

[0001] This utility model relates to the field of isolation door technology, specifically to a pneumatic isolation environment lifting door. Background Technology

[0002] In warehousing and logistics systems, it is common for materials to cross two separate compartments. To facilitate material passage while isolating the two compartments, high-speed rolling doors and double-isolation chambers are often used. However, existing high-speed rolling doors suffer from low door drive efficiency and large space requirements in double-layer material conveying situations. Utility Model Content

[0003] The purpose of this invention is to solve the problems of low transmission efficiency and large space occupation of the drive structure in existing high-speed rolling shutter doors when double-layer material conveying.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] A pneumatic isolation environment lifting door, characterized in that: it includes a main frame, a movable door that is lifted and lowered within the main frame, a set of lifting cylinders symmetrically installed on the left and right sides of the front of the main frame for driving the movable door to rise and fall, a set of lifting linear guides symmetrically installed on the left and right sides of the front of the main frame for guiding the movable door to rise and fall, a set of sealing edges symmetrically installed on the left and right inner sides of the front of the main frame, and a set of position sensors respectively installed on the upper and lower ends of the sealing edges for positioning the lifting stroke.

[0006] A further improvement is that a matching guide rail slider is slidably arranged on the lifting linear guide rail, the lifting cylinder is a rodless cylinder, and the lifting cylinder includes a cylinder slider.

[0007] A further improvement is that the movable door includes a movable door frame and a transparent door panel.

[0008] A further improvement is that the main frame and the movable door frame are made of aluminum alloy.

[0009] A further improvement is made: a door support rod is fixedly connected to the horizontal center of the front of the movable door. The two ends of the door support rod are respectively fixedly connected to the guide rail sliders on both sides through the first connecting plate. The guide rail sliders are fixedly connected to the cylinder slider on one side through the second connecting plate. The door support rod is fixed to the movable door frame.

[0010] A further improvement is that the position sensor includes an upper position sensor and a lower position sensor. A further improvement is that a sealing groove is provided on the side of the sealing edge facing the movable door, and the frame of the movable door facing the sealing edge is slidably mounted on the sealing groove.

[0011] A double-layer pneumatic isolation environment lifting door is formed by splicing two of the above-mentioned pneumatic isolation environment lifting doors, characterized in that: the two main frames are connected back to back.

[0012] Compared with existing technologies, the above technical solution has the following advantages:

[0013] The lifting cylinder raises and lowers, which in turn drives the door to rise and fall. Position sensors at the top and bottom are used to locate the door and control the upper and lower endpoints of the lifting, thus simplifying the overall structural space.

[0014] The coordination of the lifting linear guide and the lifting cylinder can better ensure the movement trajectory during operation;

[0015] Because the transmission structure of this equipment is placed on the side, when two sets are used together, they can be used in a forward or reverse configuration to achieve separate control of the upper and lower layers with a small difference in floor height. This can effectively replace the traditional high-speed rolling door structure, distinguish and isolate the environment, and has a higher space utilization rate. It can solve the problem of space occupation of the drive structure in the case of double-layer material conveying of traditional high-speed rolling doors.

[0016] The sliding door is constructed using transparent panels and an aluminum profile frame, featuring a lightweight structure and a good field of vision. Attached Figure Description

Detailed Implementation

[0023] See Figures 1-4 As shown, the technical solution adopted in this specific embodiment is: a pneumatic isolation environment lifting door, characterized in that: it includes a main frame 1, a movable door 7 that is lifted and installed in the main frame 1, a set of lifting cylinders 2 symmetrically installed on the left and right sides of the front of the main frame 1 for driving the movable door 7 to rise and fall, a set of lifting linear guide rails 5 symmetrically installed on the left and right sides of the front of the main frame 1 for guiding the movable door 7 to rise and fall, a set of sealing edges 6 symmetrically installed on the left and right inner sides of the front of the main frame 1, and a set of position sensors installed on the upper and lower ends of the sealing edges 6 for positioning the lifting stroke.

[0024] The main frame 1 is composed of split frame components 11, which can be connected to each other or installed through additional support structures.

[0025] The lifting linear guide rail 5 is slidably provided with a matching guide rail slider 51, and the lifting cylinder 2 is a rodless cylinder, which includes a cylinder slider 21.

[0026] The movable door 7 includes a movable door frame 74 and a transparent door panel 75.

[0027] The main frame 1 and the movable door frame 74 are aluminum alloy frames.

[0028] The movable door 7 has a door support rod 71 fixedly connected to the middle of the front side. The two ends of the door support rod 71 are fixedly connected to the guide rail sliders 51 on both sides through the first connecting plate 72. The guide rail sliders 51 are fixedly connected to the cylinder slider 21 on one side through the second connecting plate 73. The door support rod 71 is fixed on the movable door frame 74.

[0029] The position sensor includes an upper position sensor 3 and a lower position sensor 4.

[0030] The upper position sensor 3 and lower position sensor 4 are electrically connected to an external control circuit (not shown in the figure). This control circuit is electrically connected to the lifting cylinder 2 to control the lifting stroke. When the position sensors detect the moving door, they send a signal to the control circuit, which then controls the lifting cylinder to operate based on the signal. The control circuit can be a microcontroller or PLC-controlled circuit; the specific choice depends on the application scenario.

[0031] The lifting cylinder uses an induced check valve as an air inlet connector, which can be used in conjunction with a three-position five-way center-exhaust solenoid valve to maintain control when the air pipe is long.

[0032] The edge sealing 6 is provided with an edge sealing groove 61 on the side facing the movable door 7, and the frame 74 of the movable door 7 is slidably mounted on the edge sealing groove 61 on the side facing the edge sealing 6.

[0033] A double-layer pneumatic isolation environment lifting door is formed by splicing two of the above-mentioned pneumatic isolation environment lifting doors, with the two main frames 1 connected back to back.

[0034] The working principle of this utility model is as follows: the lifting cylinder drives the corresponding lifting of the movable door. Position sensors at the upper and lower ends are used for positioning, thereby controlling the upper and lower endpoints of the lifting. This simplifies the overall structural space. The cooperation between the lifting linear guide rail and the lifting cylinder can better ensure the movement trajectory during operation. In the double-layer conveying structure, since the transmission structure of this equipment is placed on the side, when two sets are used together, the upper and lower layers can be controlled separately with a small difference in floor height through upright and inverted installation. The movable door is constructed with transparent panels and aluminum profile frames, which has a lightweight structure and a good field of view.

[0035] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions provided are merely illustrative of the principles of this utility model.
