[0042] The specific implementation of the present invention is described in detail below in conjunction with the accompanying drawings. It should be understood that the specific implementation described here is only used to illustrate and explain the present invention, and is not used to limit the present invention.

[0043] In the present invention, unless otherwise stated, directional words such as "bottom, both ends, both sides" contained in the terms merely represent the orientation of the terms in normal use, or are common names understood by those skilled in the art, and should not be regarded as limitations on the terms.

[0044] See also Figure 1-6 The telescopic platform railing for bulk loading port comprises a fixed bracket 1, a driving device 2, a movable platform 3 and a movable railing 5, wherein the driving device 2 drives the movable platform 3 to rise and fall, and the bottom of the movable railing 5 is connected to the movable platform 3;

[0045] The movable railing 5 is connected to the fixed bracket 1 through a rotatable connecting rod 4. The two ends of the connecting rod 4 are rotatably connected to the fixed bracket 1 and the movable railing 5 respectively. The movable platform 3 pushes the movable railing 5 to rise and fall. During the process of the movable railing 5 rising and falling, the movable railing 5 approaches or moves away from the fixed bracket 1.

[0046] Through the implementation of the above technical solution, the driving device 2 drives the movable platform 3 to rise and fall, and the bottom of the movable railing 5 is connected to the movable platform 3. Therefore, during the process of the movable platform 3 rising and falling, the movable railing 5 will also rise and fall with the movable platform 3.

[0047] During the rising process of the movable railing 5, the connecting rod 4 rotates around the connection position with the fixed bracket 1, so the horizontal distance between the movable railing 5 and the fixed bracket 1 also changes with the rotation of the connecting rod 4. Preferably, during the rising process of the movable railing 5, the horizontal distance between the movable railing 5 and the fixed bracket 1 gradually decreases, so that the movable railing 5 can provide more space for the filling vehicle 10 to pass through.

[0048] Under the action of the driving device 2, the height of the movable platform 3 of the telescopic platform railing for the bulk port is adjustable, and in the process of adjusting the height of the movable platform 3, the movable railing 5 also moves up and down accordingly, and in the process of the movable railing 5 rising, the movable railing 5 will gradually approach the fixed bracket 1, thereby realizing the storage function of the telescopic platform railing for the bulk port, providing a larger use space for the filling vehicle 10. Therefore, the use of the telescopic platform railing for the bulk port can meet the use requirements of filling vehicles 10 of different sizes.

[0049] Moreover, when the movable railing 5 is at the highest position, the filling vehicle 10 can be easily driven into the loading and unloading area, and then the movable railing 5 can be lowered, so that the movable railing 5 can enclose a working area on the roof of the filling vehicle 10. After the staff reaches the roof of the filling vehicle 10, they can have more room for activities under the protection of the movable railing 5, and can move freely within the activity area.

[0050] In this embodiment, preferably, the driving device 2 includes a power member 21, a first crank 22 and a fixed shaft 23, the fixed shaft 23 is fixedly connected to the fixed bracket 1, the power member 21 is rotatably connected to the fixed bracket 1, one end of the first crank 22 is rotatably connected to the fixed shaft 23, and the other end is fixedly connected to the movable platform 3;

[0051] The power member 21 drives the first crank 22 to rotate around the fixed rotating shaft 23 .

[0052] The power member 21 drives the first crank 22 to rotate around the fixed rotating shaft 23. As the first crank 22 rotates, the movable platform 3 starts to rotate.

[0053] When the movable platform 3 is at the lowest position, the movable platform 3 is in a horizontal position. With the action of the power member 21, the first crank 22 rotates upward, and the movable platform 3 starts to rotate upward. In this way, the movable platform 3 can be raised and lowered. During use, after the upward flip is completed, the movable platform 3 does not affect the passage of the filling vehicle 10 below.

[0054] In this embodiment, preferably, the driving device 2 further comprises a second crank 24, a gap is provided between the second crank 24 and the movable platform 3, the second crank 24 and the movable platform 3 are connected via a rotating pin 25, and the bottom of the movable railing 5 is placed on the rotating pin 25;

[0055] The second crank 24 rotates synchronously with the first crank 22 .

[0056] The first crank 22 and the second crank 24 can both rotate around the fixed rotating shaft 23, and the first crank 22 and the second crank 24 rotate synchronously. That is, when the power member 21 drives the first crank 22, the second crank 24 can also rotate synchronously.

[0057] During use, as the movable platform 3 flips upward, the second crank 24 drives the rotating pin 25 to perform a circular motion upward, and the movable railing 5 located on the rotating pin 25 is lifted. Therefore, the second crank 24 lifts the movable railing 5 through the rotating pin 25.

[0058] Preferably, a limiting roller 26 is sleeved on the rotating pin 25, and limiting baffles are arranged on both sides of the limiting roller 26. The movable railing 5 is placed in the two limiting baffles, thereby realizing the limiting effect on the movable railing 5 and preventing the movable railing 5 from falling off the rotating pin 25. Under the action of the limiting roller 26 and its own weight, the movable railing 5 can maintain a reliable connection with the rotating pin 25, so that the movable railing 5 can always be located on the rotating pin 25 and has the freedom of sliding with the rotating pin 25.

[0059] In this embodiment, preferably, the movable railing 5 is rotatably connected to one end of the connecting rod 4 via a first rotating shaft 41, a second rotating shaft 42 is provided on the fixed bracket 1, and the other end of the connecting rod 4 is rotatably connected to the second rotating shaft 42;

[0060] Two connecting rods 4 are provided, the two connecting rods 4 are parallel to each other, and the two second rotating shafts 42 connected with the two connecting rods 4 are located on the same vertical line.

[0061] During the process of raising and lowering the movable railing 5, the position of the movable railing 5 can be maintained through the connecting rod 4, that is, the movable railing 5 is always kept in a horizontal state, so that no matter at what height the movable railing 5 stops, the movable railing 5 can be in a working state to provide protection for the staff.

[0062] like Figure 1As shown, the two connecting rods 4 are parallel to each other, the two second rotating shafts 42 and the two first rotating shafts 41 become the four vertices of a parallelogram, the two connecting rods 4 are two opposite sides of the parallelogram, and the side between the two second rotating shafts 42 and the side between the two first rotating shafts 41 become the other two opposite sides of the parallelogram. Since the two second rotating shafts 42 are located on the same vertical line, the side between the two second rotating shafts 42 is a vertically arranged side, and in the process of the movable railing 5 being raised and lowered, the side between the second rotating shafts 42 always remains vertically unchanged, and then the side between the two first rotating shafts 41 will also always remain vertically, which ensures that the position state of the movable railing 5 is horizontal and unchanged. Therefore, by setting two connecting rods 4, the movable railing 5 can always remain horizontal during the lifting process.

[0063] During the rotation process, since the angle between the connecting rod 4 and the horizontal direction will gradually change, during use, as the connecting rod 4 rotates, the distance between the movable railing 5 and the fixed bracket 1 will also change continuously. The connecting rod 4 is set so that when the movable railing 5 is lifted, the angle between the connecting rod 4 and the horizontal direction gradually increases. Then, when the movable railing 5 is raised, the distance between it and the fixed bracket 1 will gradually decrease.

[0064] In this embodiment, preferably, two driving devices 2 are provided, and the two driving devices 2 are respectively located on both sides of the movable platform 3 .

[0065] The two driving devices 2 are respectively located on both sides of the movable platform 3 , so that the two driving devices 2 can drive the movable platform 3 from both sides respectively, which is beneficial to the balanced force of the movable platform 3 and can also reduce the load of each driving device 2 .

[0066] In this embodiment, preferably, connecting rods 4 are respectively provided on both sides of the movable platform 3 , and the connecting rods 4 on both sides of the movable platform 3 are symmetrically arranged.

[0067] Connecting rods 4 are symmetrically arranged on both sides of the movable platform 3 to achieve reliable support of the movable platform 3 by the fixed bracket 1 .

[0068] A method for using a telescopic platform railing at a bulk loading port, the method comprising:

[0069] Step 1: lift the movable platform 3 to the highest position;

[0070] Step 2: The filling vehicle 10 enters the loading and unloading area and lowers the movable platform 3 to a suitable position;

[0071] Step 3: The staff climbs up to the top of the filling vehicle 10 and uses the surrounding movable railings 5 ​​for operation protection;

[0072] Step 4: After the operation is completed, lift the movable platform 3 to the highest point.

[0073] Through the implementation of the above technical solution, in order to provide a larger space and facilitate the passage of filling vehicles 10 of different sizes, the initial position of the telescopic platform railing used at the bulk port is set to lift the movable platform 3 to the highest position. At this time, the movable platform 3 and the movable railing 5 are both at the highest position, and the movable platform 3 and the movable railing 5 are both closer to the fixed bracket 1. Therefore, the filling vehicle 10 obtains the maximum available space in the loading and unloading area.

[0074] After the filling vehicle 10 enters the loading and unloading area and stops steadily, the movable platform 3 can be controlled to descend to a suitable position. At this time, the movable railing 5 encloses a safe working area on the roof of the filling vehicle 10, and the staff can work in the safe working area, which not only protects the life safety of the staff, but also enables the staff to obtain maximum freedom in the activity area.

[0075] After the operation is completed, the telescopic platform railing used at the bulk port needs to be restored to its original position to facilitate the next operation.

[0076] In this embodiment, preferably, in step 2, the height of the movable platform 3 can be adjusted by a control box.

[0077] The power member 21 is provided with a control box, which can control the power member 21 to start or stop. The control box is provided with a start and stop button, and the power member 21 can be started or stopped by pressing the button.

[0078] Preferably, the button on the control box is set to the inching mode. When the movable railing 5 is close to the target position, the power member 21 can be inched to make the movable railing 5 gradually approach the target position, so that the movable railing 5 can more conveniently obtain a suitable stop position.
