Description

Technical Field

[0001] The present invention relates to the technical field of detection equipment, in particular to a hydraulic lifting track movable tank truck inspection platform. Background Art

[0002] Tank trucks are important tools for loading and transporting liquefied gas, light fuel oil and other chemical products. They are mobile pressure vessels with high mobility. Tank trucks need to be inspected regularly and comprehensively. At present, some units have made special auxiliary inspection platforms. However, practice has shown that most auxiliary platforms can only be used for local inspections and cannot meet the high-altitude operation requirements of comprehensive inspections of tank trucks. They also bring many inconveniences to the inspection work: (1) At present, the inspection platforms are generally metal structures. Due to their heavy weight, several people are required to move the platforms at the same time, which is time-consuming and labor-intensive. Manual operation also poses the risk of collisions with tank trucks or people; (2) The working platform is not equipped with protection, which makes it easy for people to fall and get injured. Safety is not fully guaranteed; (3) During maintenance, maintenance tools are generally placed on the working platform, which are easy to fall; (4) The lifting mechanism of the working platform is not designed reasonably. It is generally driven by a motor, with poor load capacity and unstable movement. Therefore, there is currently a lack of a special tank truck inspection platform with safety protection functions and improved inspection efficiency. Summary of the Invention

[0003] The technical problem to be solved by the present invention is to overcome the defects of the above-mentioned technology and provide a hydraulic lifting track movable tank truck inspection platform.

[0004] To solve the above technical problems, the present invention provides a technical solution of a hydraulic lifting track mobile tanker inspection platform, comprising:

[0005] A working platform, which is used for maintenance personnel to stand on and to be raised and lowered to the position of the tank truck to be inspected;

[0006] A lifting mechanism, on which the working platform is arranged, and is raised and lowered by the lifting mechanism to adjust the vertical height;

[0007] The traveling mechanism, the lifting mechanism is arranged on the traveling mechanism, and the lifting mechanism and the working platform are driven to move by the traveling mechanism to adjust the horizontal position;

[0008] The lifting mechanism includes a frame, a gantry, a hydraulic cylinder, a lifting sprocket assembly, and a lifting bracket. The frames are symmetrically arranged, and each frame is provided with a gantry. The gantry is slidably connected to the frame, the lower end of the hydraulic cylinder is hinged to the frame, and the upper end of the hydraulic cylinder is hinged to the crossbeam of the gantry. The lifting sprocket assembly includes a chain fixing joint fixedly connected to the upper end of the frame, a driven sprocket rotatably connected to the top of the gantry, and a lifting chain. One end of the lifting chain is fixedly connected to the chain fixing joint, and the other end of the lifting chain is fixedly connected to the lifting bracket after passing around the driven sprocket. The lifting bracket is slidably connected to the gantry, and the working platform is fixedly connected to the lifting bracket.

[0009] Furthermore, the walking mechanism includes a walking driven wheel and a walking driving wheel, and a walking track, respectively arranged at the two ends below the frame. The walking driving wheel is connected to the walking driving wheel through a walking chain. The walking driving wheel and the walking driven wheel are arranged on the walking track and can roll along the walking track.

[0010] Furthermore, a guardrail is provided on the upper edge of the working platform, and a hydraulic system is provided on the frame.

[0011] Furthermore, an operation hole is opened at the center of the working platform, and the operation hole is a transverse long hole, which solves the problem that the deviation of the tank truck's docking position relative to the center position of the walking track affects the operation.

[0012] Furthermore, skirting boards are provided around the working platform, and disassembled parts can be directly placed on the working platform for use without having to worry about rolling off the tank body or being lost.

[0014] The advantages of the present invention compared with the prior art are:

[0015] (1) According to the part to be inspected, the work platform is controlled to lift, lower, move forward and backward to make the work platform reach the inspection position, so as to realize the inspection of different points. It is convenient and quick. Since it is controlled and adjusted, and the inspection platform only moves forward and backward, it also avoids the risk of collision with tank trucks or personnel.

[0016] (2) The working platform is equipped with surrounding guardrails to prevent personnel from falling and causing injury, and safety is fully guaranteed;

[0017] (3) The operators move up and down with the working platform, and no longer need to carry tools and instruments up and down, which consumes physical energy. Before the operation, all the instruments and tools required for the inspection can be placed on the working platform, which reduces the labor intensity of the operators and saves working time;

[0018] (4) The working platform is equipped with a skirting board around it, and the disassembled parts can be directly placed on the working platform for use without having to worry about rolling off the tank or being lost. At the same time, it solves the hidden danger of personal safety accidents caused by falling parts, which is safe, convenient and efficient.

[0019] (5) After the inspection is completed, the working platform moves out of the tanker position along the walking track, and the hydraulic cylinder and hydraulic motor lower the working platform to the ground, and the personnel evacuate, which is very convenient;

[0020] (6) The platform is fully hydraulically driven, with strong load-bearing capacity, smooth movement, stable operation, and easy operation. It can be equipped with a balance valve safety device to make it safer and more reliable;

[0021] (7) It has a wide range of applications and is not restricted by the length and height of tank trucks, and covers all types of national standard tank trucks. BRIEF DESCRIPTION OF THE DRAWINGS

[0027] To make the objectives, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions of the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Generally, the components of the embodiments of the present invention described and shown in the drawings herein can be arranged and designed in various different configurations.

[0028] Example 1, combined with the attached Figure 1-3 , a hydraulic lifting track mobile tanker inspection platform, comprising:

[0029] A working platform 1, which is used for maintenance personnel to stand on and to be raised and lowered to the position of the tank truck to be inspected;

[0030] A lifting mechanism, on which the work platform 1 is mounted, is raised and lowered by the lifting mechanism to adjust the vertical height;

[0031] The traveling mechanism, the lifting mechanism is arranged on the traveling mechanism, and the lifting mechanism and the working platform 1 are driven by the traveling mechanism to move and adjust the horizontal position;

[0032] The lifting mechanism includes a frame 2, a gantry 3, a hydraulic cylinder 4, a lifting sprocket assembly, and a lifting bracket 5. Two frames 2 are provided, and the two frames 2 are symmetrically arranged and walk on corresponding walking rails 11 respectively, similar to a traveling frame. Each frame 2 is provided with a gantry 3, and the gantry 3 is slidingly connected to the frame 2. The lower end of the hydraulic cylinder 4 is hinged to the frame 2, and the upper end of the hydraulic cylinder 4 is hinged to the crossbeam of the gantry 3. The lifting sprocket assembly includes a chain fixing joint 6 fixedly connected to the upper end of the frame 2, a driven sprocket 7 rotatably connected to the top of the gantry 3, and a lifting chain 8. One end of the lifting chain 8 is fixedly connected to the chain fixing joint 6, and the other end of the lifting chain 8 is fixedly connected to the lifting bracket 5 after passing around the driven sprocket 7. The lifting bracket 5 is slidingly connected to the gantry 3, and the working platform 1 is fixedly connected to the lifting bracket 5.

[0033] A guardrail 14 is provided on the upper edge of the working platform 1 , and a hydraulic system is provided on the frame 2 .

[0034] When in use, when the hydraulic cylinder 4 drives the gantry 3 to rise, the driven sprocket 7 is forced to rotate, and the end of the lifting chain 8 connected to the lifting bracket 5 rises, thereby driving the lifting bracket 5 to rise, and the working platform 1 rises at the same time. Similarly, when the hydraulic cylinder 4 drives the gantry 3 to descend, the lifting bracket 5 and the working platform 1 descend at the same time under the action of gravity, and the driven sprocket 7 is forced to rotate in the opposite direction, so that the lifting chain 8 always remains tensioned while the lifting bracket 5 and the working platform 1 are lowered, so as to achieve the lifting and retraction control of the working platform 1 by the extension of the hydraulic cylinder 4 and adjust the height. After the working platform 1 is raised, the lifting mechanism and the working platform 1 are driven to move by the walking mechanism to adjust the horizontal position, so that the entire inspection platform moves back and forth on the tank truck. After reaching the inspection position, the working platform 1 is placed on the tank top for inspection. The same method is used to inspect different points on the same tank truck. Workers ascend and descend with the work platform 1, eliminating the need to carry tools and instruments and expend the energy of climbing up and down. Before work begins, all instruments and tools required for inspection can be placed on the work platform 1, reducing labor intensity and saving time. By moving the inspection platform to the rear of the vehicle, the height of the work platform 1 drops below the rear end cap, allowing operations on tank trucks with manholes located in the rear end cap. This expands the scope of application, meeting both top-of-the-line inspection and rear end cap opening requirements. Since inspectors operate from the work platform throughout the entire inspection process, they avoid the traditional climbing-on-top inspection method. They maintain a stable footing and are unaffected by rain, snow, frost, or freezing weather. This prevents slipping and other safety incidents, ensuring the safety of inspectors. After the inspection is completed, the work platform 1 is moved out of the tank truck's position via the traveling mechanism. The hydraulic cylinder 4 drives the lifting bracket 5 and the work platform 1 downward, allowing the height of the work platform 1 to be adjusted to near the ground, facilitating evacuation. The working platform 1 is a common maintenance working platform, and the structure of the lifting bracket 5 is a common component that plays a supporting role, so it will not be described in detail here.

[0035] In this embodiment, the travel mechanism includes a driven wheel 9 located at one end below the frame 2, a driving wheel 10 located at the other end below the frame 2, and a track 11 pre-installed along the inspection site. The driving wheel 10 is connected to a drive wheel 13 via a chain 12. The drive wheel 13 is driven by a hydraulic motor. The driving wheel 10 and the driven wheel 9 are mounted on the track 11 and can roll along the track 11. The hydraulic motor drives the drive wheel 13, which in turn rotates the driving wheel 10, causing the driving wheel 10 and the driven wheel 9 to roll forward and backward along the track 11, meeting the inspection requirements for different vehicle lengths. The hydraulic cylinder 4 and hydraulic motor are both connected to the hydraulic system, utilizing a fully hydraulic transmission system for smooth operation and ease of operation. A balancing valve safety device can be installed to further enhance safety and reliability.

[0036] In this specific embodiment, the hydraulic system includes a hydraulic operating platform, which is arranged on the working platform 1, wherein the hydraulic operating platform is controlled by operating the valve stem. The staff only needs to operate the valve stem to move the working platform 1 to different points for inspection, thereby facilitating operation.

[0037] In this specific embodiment, an operation hole is opened at the center of the working platform 1, and the operation hole is a transverse long hole, thereby solving the problem that the deviation of the tank truck's docking position relative to the center position of the walking track 11 affects the operation.

[0038] In this specific embodiment, the guardrail 14 is an enclosing guardrail, thereby avoiding accidents in which people fall and get injured, and safety is fully guaranteed.

[0039] In this specific embodiment, skirting boards are provided around the working platform 1, so that the disassembled parts can be directly placed on the working platform 1 for use without having to worry about rolling off the tank body or being lost. At the same time, the hidden danger of personal safety accidents caused by falling parts is solved, which is safe, convenient and efficient.

[0040] In this specific embodiment, a miniature single-arm crane can also be placed on the working platform 1 to lift the manhole cover during the disassembly and assembly process, thereby further reducing labor intensity.

[0041] In the description of the embodiments of the present invention, it should be noted that if the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", etc. appear, the orientation or position relationship indicated is based on the orientation or position relationship shown in the accompanying drawings, or the orientation or position relationship in which the product of the invention is usually placed when in use. It is only for the convenience of describing the present invention and simplifying the description, and does not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operate in a specific orientation. Therefore, it should not be understood as limiting the present invention. In addition, the terms "first", "second", "third", etc. are only used to distinguish the description and should not be understood as indicating or implying relative importance.

[0042] Furthermore, the use of terms such as "horizontal," "vertical," and "overhanging" does not necessarily imply that the component must be absolutely horizontal or overhanging, but rather that it can be slightly tilted. For example, "horizontal" simply means that its direction is more horizontal than "vertical," not that the structure must be completely horizontal, but rather that it can be slightly tilted.

[0043] In the description of the embodiments of the present invention, "a plurality of" means at least two.

[0044] In the description of the embodiments of the present invention, it should be noted that, unless otherwise expressly specified or limited, the terms "disposed," "installed," "connected," and "connected" should be understood in a broad sense. For example, they can refer to fixed connections, detachable connections, or integral connections; they can refer to mechanical connections or electrical connections; they can refer to direct connections or indirect connections through an intermediate medium; and they can refer to internal connections between two components. Those skilled in the art will understand the specific meanings of the above terms in the present invention based on specific circumstances.

[0045] The present invention and its embodiments are described above. This description is not restrictive. The drawings show only one embodiment of the present invention, and the actual structure is not limited thereto. In short, if a person skilled in the art is inspired by this and, without departing from the purpose of the present invention, designs structures and embodiments similar to this technical solution without inventiveness, they shall fall within the scope of protection of the present invention.
