DETAILED DESCRIPTION

[0018] The directional words mentioned in the following embodiments, such as "up", "down", "left", "right", etc., are only referenced to the directions of the drawings. Therefore, the directional words used are used to illustrate rather than limit the invention of the utility model.

[0019] like Figure 1 As shown, a liftable loading operation platform includes a support 1 and a hydraulic lifting device 2, and the top of the hydraulic lifting device 2 is fixedly connected with an operating platform assembly; the operating platform can be allowed to be lifted and lowered as needed to adapt to tank trucks 5 of different heights. The operating platform assembly includes a fixed platform 32 and a climbing frame 31, and the climbing frame 31 at one end of the fixed platform 32 provides a convenient up and down passage for the staff. The fixed platform 32 is connected to the support 1 by sliding up and down to ensure the stability of the platform and the smoothness of lifting and lowering. A loading hole is provided at the bottom of the fixed platform 32, and a bottom plate is hinged on the loading hole. The serrated protrusions provided on the bottom plate increase the friction between the bottom plate and the ground, preventing the bottom plate from sliding during operation, thereby ensuring the stability and safety of loading. The setting of the bottom plate can make the working position closer to the inside and relatively safer. A loading crane pipe for filling the tank truck 5 is installed on the fixed platform 32, and the loading crane pipe can be operated to pass through the loading hole, which can make the filling process more convenient and efficient. It provides operators with a safe and reliable operating environment throughout the entire process; reduces operating risks for operators and alleviates their workload; and can be flexibly and safely adjusted according to tank trucks 5 of different heights and lengths, so that the height of the tank truck 5 can be matched for loading or sampling.

[0020] Furthermore, the hydraulic lifting device 2 is externally connected to a hydraulic station power control assembly 4, which can accurately control the lifting process and speed of the hydraulic lifting device 2, thereby achieving accurate control of the lifting of the operating platform, ensuring that the operating platform can be stably and safely lifted to a predetermined position.

[0021] In order to further improve the safety of operation, a distance sensor is installed on the side of the support 1 to identify the height of the filling port of the tank truck 5. This enables the operating platform to automatically adjust to a height that matches the filling port, thereby improving the automation and efficiency of loading. At the same time, a limit switch is fixedly connected to the bottom of the fixed platform 32 to prevent collision with the tank truck 5 and ensure safety during operation.

[0022] In order to ensure the stability of the operating platform, a T-shaped guide groove is vertically provided on the support 1, and a T-shaped guide block is fixedly connected to the side of the fixed platform 32, and the T-shaped guide block is slidably connected to the T-shaped guide groove up and down. This can effectively prevent the operating platform from shaking and deflecting during the lifting process, ensuring the stability and safety of the operation.

[0023] In addition, a mounting seat is fixedly connected to the bottom of the support 1 on one side of the T-shaped guide groove opening, and the hydraulic lifting device 2 is installed on the mounting seat. This installation method makes the entire operating table structure more stable and can withstand greater loads and impact forces. The loading crane pipe adopts a multi-link setting and is driven and controlled by a cylinder so as to extend and swing; specifically, it includes a bracket 331 fixedly connected to the fixed platform 32, a first boom 332 is hinged on the upper part of the bracket 331, a first cylinder 333 is hinged on the lower part of the bracket 331, the output end of the first cylinder 333 is hinged on the lower side of the first boom 332, a second boom 334 is hinged on the end of the first boom 332, a second cylinder 335 is hinged on the lower side of the first boom 332, the output end of the second cylinder 335 is hinged on the second boom 334, and a feeding pipe 336 is connected to the lower end of the second boom 334; the first boom 332 and the second boom 334 are both tubular structures; the position of the feeding pipe 336 can be adjusted by the first boom 332 and the second boom 334. The hydraulic lifting device 2 is a hydraulic cylinder. Guardrails are installed on both sides of the climbing frame 31 and the fixed platform 32.

[0024] Working principle: When the tank truck 5 enters the designated fixed-point loading position, the liftable operating platform is parked at the upper limit of the safety height, which is higher than the safe height at which the tank truck 5 can pass. When the tanker 5 enters the loading position, the hydraulic station power control assembly 4 is started, and the execution system hydraulic cylinder moves downward synchronously through the "down" button on the external control panel, the distance sensor recognizes the tanker 5 in real time, and the limit switch stops moving before contacting the tanker 5; the tanker 5 is flexibly adjusted to land in place according to the different heights and lengths, and the limit switch can prevent the equipment from being placed on the tanker 5; the operator controls the operation to make the operating platform assembly land to the limited position of the tanker 5, and then reaches the position of the liftable operating platform from the climbing frame 31, observes the position of the tank mouth of the tanker 5, opens the bottom plate on the upper side of the tank mouth, and automatically moves the loading crane pipe to the tank mouth position through hydraulic pressure, and then the loading operation can be carried out; after the loading operation is completed, the loading crane pipe is automatically retracted to the home state; the bottom plate is flipped and reset, and the execution system hydraulic cylinder moves upward synchronously through the "up" button on the external control panel, and the limit switch stops moving when it contacts the limiter on the support 1. After inspection and verification, the tanker 5 can leave.

[0025] Example 2

[0026] The difference from Example 1 is that the side of the fixed platform 32 is rotatably connected to the T-shaped guide block and is designed to be lockable, so that the tilt angle can be adjusted to facilitate matching the slope of the top of the tank truck 5.
