Description

Technical Field

[0001] This utility model relates to the field of safety equipment technology, and more specifically, to a sampling device and a transport vehicle system. Background Technology

[0002] In industrial production, the quality inspection of liquid additives is particularly important, serving as the first line of defense in ensuring product quality. The transportation of liquid additives mainly relies on tank trucks, and sampling and acceptance are required before unloading. Tank truck sampling generally employs a top-mounted sampling method. One way to reach the top of the tank truck is via its built-in ladder. However, this method makes it difficult to carry sampling tools, and the lack of guardrails on the ladder poses a risk of falls. Another method is to use a separate, dedicated sampling ladder. Traditional ladders are movable and retractable, but these are expensive, have unstable foundations, and are difficult to transport.

[0003] Therefore, it is urgent to solve the problems of unstable operation and low safety and reliability of traditional ladders.

[0004] Therefore, this application is submitted. Utility Model Content

[0037] Furthermore, the terms "first" and "second" are used only to distinguish descriptions and should not be interpreted as indicating or implying relative importance.

[0038] It should be noted that, where there is no conflict, the features in the embodiments of this utility model can be combined with each other.

[0039] Please refer to Figure 1 and Figure 2 This utility model embodiment provides a sampling device 100, including a ladder 110, a waiting platform 120, a connecting platform 130, and a drive device 140. Operators can climb the ladder 110 to reach the waiting platform 120. After the transport vehicle 001 (such as a tank truck) arrives at the designated location, the drive device 140 drives the connecting platform 130 to open, allowing sampling to be performed through the connecting platform 130. The operation is convenient, requires no movement, and ensures safe and reliable sampling.

[0040] Furthermore, one end of the ladder 110 is for contact with the ground, and the other end is connected to the waiting platform 120. Operators can climb onto the waiting platform 120 via the ladder 110. The waiting platform 120 is used for operators to wait for sampling. After the transport vehicle 001 (such as a tank truck) arrives at the designated position, the drive device 140 drives the connecting platform 130 to open. The connecting platform 130 corresponds to the position of the waiting platform 120, and the operator can continue to move forward from the waiting platform 120 to the connecting platform 130 to take samples from the transport vehicle below the connecting platform 130.

[0041] Specifically, the structure of the ladder 110 is not limited, as long as it allows operators to climb from the ground to the waiting platform 120. The waiting platform 120 can be a horizontal platform or a near-horizontal platform. The drive device 140 can be located below the end of the connecting platform 130 near the waiting platform 120. The drive device 140 can be a common drive motor capable of driving the connecting platform 130 to rotate, such as a commercially available ultra-low speed special motor. It can be equipped with a sensor for positioning, so that the connected platform 130 driven by it can rotate within a specified range. When it is horizontally opened, it cannot be opened downwards, thus eliminating the risk of operators falling due to the connecting platform opening downwards.

[0042] In some embodiments, the connecting platform 130 has an active state and an inactive state under the drive of the drive device 140. When the connecting platform 130 is in the active state, it docks with the waiting platform 120, allowing operators to walk from the waiting platform 120 to the connecting platform 130; when the connecting platform 130 is in the inactive state, it retracts upwards from the active state. Figure 1 and Figure 2 These are all diagrams showing the state of the connecting platform 130 when it is in working condition. When the connecting platform 130 is not in working condition, it can be in a state that is approximately perpendicular to the waiting platform 120, which can also protect the operators on the waiting platform 120.

[0043] In some embodiments, a control box 150 is also included. The control box 150 is mounted above the waiting platform 120 and is electrically connected to the drive device 140 to control the rotation of the connecting platform 130. A button may be provided on the control box 150; pressing the start button activates the drive device 140, thereby driving the connecting platform 130 to rotate. A button lock may also be provided on the control box 150 to prevent accidental activation by unauthorized personnel.

[0044] In some embodiments, a first handrail 131 may be provided on the side of the connecting platform 130 to prevent operators from falling off the connecting platform 130 and improve operational safety. A limiting device may be provided on the connecting platform 130 to prevent downward rotation under horizontal conditions, ensuring that the platform does not retract or fall during personnel sampling, making it convenient to use, requiring no movement, and ensuring safe and reliable sampling. The size of the connecting platform 130 is not limited; its length can be 2000mm, greater than half the width of a conventional tank truck, allowing it to connect to the top of the tank truck without a span. The connecting platform 130 has a load-bearing capacity of 500Kg, which can meet the needs of adults within the corresponding weight range for operation.

[0045] Furthermore, a platform support column 121 is provided at the bottom of the waiting platform 120. The bottom of the platform support column 121 contacts the ground, and the top is connected to the waiting platform 120, providing support. Please refer to... Figure 3 A protective device 122 is connected to the platform support column 121. The protective device 122 is located below the connecting platform 130. The protective device 122 protects the drive device 140 and the connecting platform 130, preventing the drive device 140 from driving the connecting platform 130 to rotate too much. When the rotation angle is too large, it can support the connecting platform 130.

[0046] In some embodiments, the protective device 122 includes a horizontal support arm 123, a vertical support arm 124, and an inclined support arm 125. The bottom of the inclined support arm 125 is connected to the platform support column 121, and the top of the inclined support arm 125 is connected to the horizontal support arm 123. One end of the horizontal support arm 123 is connected to the platform support column 121, and the other end is connected to the bottom of the vertical support arm 124. When the connecting platform 130 is not in operation, the top of the vertical support arm 124 is spaced apart from the connecting platform 130, leaving a small gap, and does not contact the connecting platform 130. The support structure formed by the horizontal support arm 123, the vertical support arm 124, and the inclined support arm 125 is relatively stable and can provide good support when the rotation angle is too large.

[0047] Please combine Figure 4 , Figure 5 and Figure 6 The staircase 110 includes a first staircase section 111 and a second staircase section 112. The top of the first staircase section 111 is connected to the bottom of the second staircase section 112, and the top of the second staircase section 112 is connected to one end of the waiting platform 120. A turning platform is provided at the connection between the first staircase section 111 and the second staircase section 112. By setting the first staircase section 111 and the second staircase section 112, an intermediate turning transition is achieved, which can reduce the overall footprint of the device and improve operational safety.

[0048] Furthermore, the inclination angle of the first ladder section 111 is 38-40°, and the inclination angle of the second ladder section 112 is 40-42°. The aforementioned "inclination angle" refers to the angle with respect to the horizontal plane. The inclination angle of the first ladder section 111 can be 38°, 39°, 40°, etc.; the inclination angle of the second ladder section 112 can be 40°, 41°, 42°, etc. The total height of the first ladder section 111 and the second ladder section 112 matches the height of the tank truck, thereby reducing the footprint of the ladder projection and making it suitable for installation in spaces with limited space.

[0049] In some embodiments, a second handrail 113 is provided on at least one side of the second staircase section 112, and the other can be abutted against a building wall. This allows for the reduction of sampling ladder construction materials and cost savings while ensuring safety. In the absence of a building, handrails must be provided on both sides of the second staircase section 112. Handrails may also be provided on the first staircase section 111, and this is not a limitation.

[0050] Furthermore, a ladder support member 114 can be provided at the bottom of the ladder 110. The top of the ladder support member 114 is connected to the ladder 110, and the bottom of the ladder support member 114 is used to contact the ground. The ladder support member 114 can support the ladder 110, making the device operate more stably.

[0051] It should be noted that the dimensions of each part of the sampling device 100 provided in this embodiment of the present invention are not limited, and can be reasonably designed according to the dimensions of the transport vehicle 001. The material of the sampling device 100 can be stainless steel, alloy, or other materials.

[0052] It should be noted that the working principle of the sampling device 100 provided in this embodiment of the present invention is as follows: In use, sampling personnel climb the ladder 110 from the ground to the waiting platform 120. After the tanker truck arrives at the designated position (i.e., below the connecting platform), the personnel press the open button on the button control box, and the connecting platform 130 opens. After the connecting platform 130 opens to a horizontal position, it connects with the top of the tanker truck. The personnel then climb onto the top of the tanker truck via the connecting platform 130 to take samples. After successful sampling, the personnel return to the personnel waiting platform 120 via the connecting platform 130 and press the close button on the button control box, and the connecting platform 130 retracts to the designated position. The personnel then return to the ground via the sampling ladder, and the sampling process ends.

[0053] This utility model embodiment also provides a transport vehicle system, including a transport vehicle 001 and a sampling device 100 provided in this utility model embodiment. The transport vehicle 001 can be a tank truck, but is not limited thereto. The heights of the waiting platform 120 and the connecting platform 130 in the sampling device 100 are perfectly matched with the transport vehicle 001, and the sampling operation can be easily completed on the connecting platform 130.

[0054] In summary, this utility model provides a sampling device and transport vehicle system, which has the following advantages:

[0055] (1) By connecting the platform and the drive limit protection device, and by fixing the installation, the tank truck sampling operation can be fast, efficient and safe.

[0056] (2) During the sampling and climbing operation, the personnel walk along a uniform and safe route without shaking. After landing on the top of the tanker truck, the connecting platform is always open, and personnel can return to the ladder at any time through the connecting platform and land safely.

[0057] (3) The sampling device is installed in a fixed position, which in turn results in a fixed route for the tanker truck, avoiding the situation where multiple tanker trucks are sampled at the same time and cross-operations, thus ensuring vehicle safety.

[0058] In summary, the sampling ladder for transport vehicles provided by this utility model has a simple structure, is easy to operate, flexible to adjust, has stable performance, low energy consumption, and high efficiency.

[0059] The above are merely specific embodiments of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model.
