[0037] In this embodiment, the connection relationship (welding, hinging, bolt fixing, etc.) of each structure is clear through the reference numerals, an integrated protection structure of “vertical buffer (first buffer pad 3+spring 25) + horizontal buffer (second buffer pad 29) + self-adaptive clamping (first electric push rod 27+arc-shaped clamping plate 28) + positioning (second electric push rod 52+fixed seat 4)” is constructed, and it is ensured that the filter is not impacted and displaced during the transfer process.

[0038] Specifically, the first buffer pad 3 and the second buffer pad 29 are both made of butyronitrile rubber (Shore hardness 50-60HA) and are connected to the corresponding parts (the top of the placement plate 21 and the inner side of the arc-shaped clamping plate 28) by full-adhesion.

[0039] In this embodiment, the material, connection method and anti-skid structure of the buffer pad are specified. Butyronitrile rubber has both elasticity and corrosion resistance to ammonia water, full-adhesion connection avoids falling off, and anti-skid lines prevent the filter from sliding, further improving the protection reliability.

[0040] Specifically, the slide rod 22 is made of 45# steel (diameter 20-30mm), and the annular limiting protrusion is integrally formed with the slide rod 22 (the protrusion diameter is 5-8mm larger than the diameter of the slide rod 22); the spring 25 is made of 65Mn steel, and the free length is 1.2 times the length of the exposed section of the slide rod 22.

[0041] In this embodiment, the material and size parameters of the slide rod 22 and the spring 25 are specified to ensure the bearing strength of the slide rod 22 (adapted to the filter weight of 50-100kg) and the spring 25 can provide sufficient reset force and buffer stroke.

[0042] Specifically, the movable frame 24 is made of aluminum alloy, the lengths of the three movable frames 24 are consistent, and the included angles along the circumferential direction of the transfer base 11 are all 120°.

[0043] In this embodiment, it is ensured that the clamping force of the three arc-shaped clamping plates 28 on the filter is uniformly distributed, avoiding excessive local stress that causes deformation of the filter housing.

[0044] Specifically, the controller 51 is built-in PLC module (model S7-200) and is provided with a touch screen (used for setting pressure threshold and displaying real-time pressure); the first pressure sensor 6 is a piezoelectric sensor, and the second pressure sensor is a thin film pressure sensor.

[0045] In this embodiment, the specific model and parameters of the control core and the sensor are specified to ensure accurate pressure signal acquisition and quick response of the controller to realize automatic adjustment.

[0046] Specifically, the output end of the second electric push rod 52 is provided with a rubber anti-skid sleeve (thickness 2mm); the inner wall of the positioning hole of the fixed seat 4 is provided with a wear-resistant coating (polytetrafluoroethylene material, thickness 0.1mm).

[0047] In this embodiment, the rubber anti-skid sleeve enhances the stability of the cooperation between the second electric push rod 52 and the positioning hole, and the wear-resistant coating reduces the wear of the positioning hole caused by long-term plugging and un-plugging, prolonging the service life of the device.

[0048] Specifically, the transfer base 11 is a rectangular frame (material Q235 steel, wall thickness 5-8mm), and the bottom edge is welded with an anti-collision strip (rubber material, height 50mm).

[0049] In this embodiment, the carrying strength of the transfer base 11 is improved, and the anti-collision strip can avoid damage to the base and other equipment during the transfer process.

[0050] The working principle and use process of the utility model are as follows:

[0051] The operator pushes the transfer base 11, moves the device to the side of the filter to be transferred through the universal wheel; steps on the foot brake of the universal wheel, locks the position of the device, and ensures that the transfer base 11 is stable (without shaking);

[0052] Filter loading stage:

[0053] Step 1: slowly lower the filter with a small lifting device (such as a manual hoist), until the bottom of the filter contacts the first buffer pad 3;

[0054] Step 2: the first buffer pad 3 is deformed under the gravity of the filter, driving the placement plate 21 to move downward; the placement plate 21 drives the sliding rod 22 to slide downward along the linear bearing, the sliding rod 22 compresses the spring 25, and the spring 25 deforms to absorb part of the vertical impact force;

[0055] Step 3: when the sliding rod 22 moves downward, the three movable frames 24 are pulled by the connecting rod 23 to move synchronously towards the center of the transfer base 11; the movable frame 24 slides along the guide rod 14 and the guide groove 13, and the bottom block 26 slides along the sliding groove 12, ensuring smooth movement of the movable frame 24;

[0056] Step 4: when the bottom of the placement plate 21 touches the pressure sensor one 6, the pressure sensor one 6 transmits a signal to the controller 51;

[0057] Step 5: the controller 51 simultaneously starts two actions: ① controls the second electric push rod 52 to extend, and the output end with a rubber anti-skid sleeve is inserted into the positioning hole of the fixed seat 4, locking the position of the placement plate 21, the shape of the positioning hole matches the shape of the output end of the second electric push rod 52 and the rubber anti-skid sleeve, and the shape of the positioning hole is circular; ② controls the three first electric push rods 27 to extend synchronously, and drives the arc-shaped clamping plate 28 to move towards the filter until the second buffer pad 29 contacts the filter shell;

[0058] Step 6: the pressure sensor two collects the clamping pressure signal in real time, when the pressure reaches the preset threshold value (set by the touch screen of the controller 51), the controller 51 instructs the first electric push rod 27 to stop extending, and the loading is completed (the filter is not shaken and not squeezed);

[0059] Transfer running stage:

[0060] Release the brake pads on the caster wheels, and the operator pushes the device to the target position;

[0061] If the road surface is bumpy: the first buffer pad 3 absorbs the vertical vibration energy through deformation; if the filter tends to shift horizontally due to inertia: the second buffer pad 29 absorbs the horizontal impact through deformation to avoid rigid collision between the filter and the arc-shaped clamping plate 28.

[0062] Real-time monitoring: Pressure sensor 2 continuously transmits pressure signals to controller 51. If the clamping pressure exceeds the safe range due to bumps, controller 51 automatically adjusts the extension and retraction of the first electric push rod 27 to ensure that the pressure returns to the threshold.

[0063] Unloading and Reset Phase:

[0064] Step 1: After moving the device to the target position, press the brake pads on the swivel wheel to lock the device;

[0065] Step 2: Send an "unload command" through the touch screen of controller 51. Controller 51 controls the three first electric push rods 27 to retract synchronously, the arc-shaped clamping plate 28 moves away from the filter, and the pressure sensor value returns to zero.

[0066] Step 3: The controller 51 controls the second electric push rod 52 to retract, and its output end is pulled out from the positioning hole of the fixed base 4, releasing the locking of the placement plate 21;

[0067] Step 4: Use hoisting equipment to lift the filter smoothly and detach it from the first buffer pad 3; under the action of elastic restoring force, the spring 25 drives the placement plate 21 to rise back to the initial position through the slide rod 22;

[0068] Step 5: When the signal from pressure sensor 6 disappears, controller 51 automatically resets, and the second electric push rod 52 remains in the retracted state, completing one transfer process;

[0069] The core principle of this device is the synergy of "mechanical linkage + automatic control + double buffering":

[0070] Vertical buffering principle: The filter's gravity triggers the placement plate 21 to move downwards. The deformation of the first buffer pad 3 and the compression / reset of the spring 25 achieve vertical vibration absorption. At the same time, the cooperation between the second electric push rod 52 and the fixed base 4 prevents the placement plate 21 from shifting during transportation.

[0071] Horizontal clamping and buffering principle: The slide bar 22 drives the movable frame 24 through the connecting rod 23 to achieve the initial approach of the arc-shaped clamping plate 28; then, through the precise extension and retraction of the first electric push rod 27 and the feedback of the second pressure sensor, "adaptive clamping" is achieved, while the second buffer pad 29 avoids rigid collisions;

[0072] The automation control principle is: taking the controller 51 as the core, receiving the signals of the pressure sensor one 6 and the pressure sensor two, driving the first electric push rod 27 and the second electric push rod 52 to act, without manual intervention clamping strength and positioning, reducing the operation error.

[0073] The circuits, electronic components and modules involved are prior art, and those skilled in the art can realize them without unnecessary description, and the content protected by the utility model does not involve improvement of software and methods.

[0074] The above is only a preferred embodiment of the utility model, and does not limit the utility model, and any modification, equivalent replacement and improvement within the spirit and principle of the utility model should be included in the protection scope of the utility model.
