Description

Technical Field

[0001] The utility model relates to a scissor-type hydraulically lifted tank truck inspection operating platform, belonging to the technical field of oil tank truck safety detection. Background Art

[0002] In the existing technology, the foundation of the inspection platform is mostly a tall gantry frame structure or a cantilever platform structure. The tall gantry frame occupies a large space and has a large deadweight, while the inspection platform is mostly small and can hardly accommodate a large number of inspectors to carry out inspection work at the same time, which has a poor effect on improving actual work efficiency. At the same time, the inspection platform of the gantry frame structure in the existing technology is not movable as a whole or has no restrictions on the movement mode, which cannot take into account both flexibility and safety. As for the cantilever platform structure, since the platform foundation must be erected on the curved surface of the tank body after the cantilever is extended, the two are not in fixed contact and are prone to shaking that is unsafe. At the same time, the sliding friction generated by the contact surface of the two may damage the paint layer on the surface of the tank body, causing the tank body to rust. Therefore, in order to solve the above problems, it is urgent to design a scissor-type hydraulic lifting tank truck inspection operation platform. Utility Model Content

Target; The walking mechanism is installed on the pre-buried ground track, and is used to execute the horizontal displacement instruction of the operating platform along the length direction of the inspected tank car issued by the controller; the basis of the lifting mechanism is the walking mechanism, which is used to execute the vertical lifting instruction issued by the controller to lift personnel and equipment to the specified height; the protection device is connected to the walking mechanism and the lifting mechanism through the controller. The protection device detects the interaction between personnel and the operating platform in real time during the operation of the equipment, and is used to prevent the occurrence of some dangerous conditions in advance, or forcibly take over the signal control of the operating platform when the emergency signal is triggered, so as to prevent the expansion of the emergency situation and the occurrence of accidents; the alarm device is a common sound and light alarm device in the prior art, which can be used to remind and warn the inspection personnel and people near the platform to pay attention to the surrounding environment when the operating platform is in action, so as to prevent the occurrence of safety accidents such as collisions and scratches;

[0005] When in use, first set the operating platform to the initial state, that is, move the lifting mechanism to the lowest point, so that the inspector can place the inspection instrument in the middle of the operating platform. After all personnel enter the safety fence of the operating platform from the side ladder, the protection device is turned on; then, the inspector operates the controller at the human-machine interaction panel to control the vertical lifting and horizontal displacement of the operating platform to the top manhole of the inspected tank truck, and fine-tunes the docking window in the middle of the mobile operating platform to align the docking window with the manhole position; at the same time, during the movement of the operating platform, the alarm device turns on the movement warning function; when the inspection is completed, the inspector controls the operation of the operating platform through the human-machine interaction panel and returns to the initial state; during operation, the motion warning function of the alarm device will be triggered; when the operating platform is in the initial state and the protection device is turned on, the inspector releases the protection device by operating the unlocking function of the controller, and the inspector leaves the operating platform.

[0006] Furthermore, an inspection channel for the inspected tank truck to pass through is reserved between each set of the ground tracks.

[0007] Furthermore, the walking mechanism includes a base, a walking motor installed on the top of the base, and a transmission shaft driven by the walking motor through a transmission sprocket; the transmission shaft is rotatably installed under the base, and rollers for matching the ground track are respectively installed at both ends of the transmission shaft; when moving, the walking motor is controlled by the controller, and the transmission sprocket is driven by the walking motor to rotate, thereby driving the transmission shaft to rotate, and then driving the roller to roll on the ground track, so that the equipment can move back and forth on the ground track.

[0008] Furthermore, the lifting mechanism is a hydraulically driven scissor-type lifting platform, wherein the scissor-type lifting platform is a common lifting platform in the prior art, and its specific structure and working principle are not described in detail here.

[0009] Furthermore, a human-computer interaction panel is installed on the controller, and the human-computer interaction panel is electrically connected to the controller.

[0010] Furthermore, the controller is composed of a microprocessor and a minimum system thereof.

[0011] Furthermore, the protection device includes but is not limited to a lifting height limiter, a stroke limiter and an amplitude limiter; wherein, the lifting height limiter is used to prevent the operating platform from being raised or lowered too much, which is not conducive to the inspection personnel entering the inspected tank truck, and when the lifting height reaches a preset value, the lifting height limiter can cut off the power supply of the lifting mechanism through the controller; the stroke limiter is used to control the horizontal movement distance of the operating platform to prevent the operating platform from moving out of the ground track, and when the preset maximum or minimum stroke is reached, the stroke limiter can cut off the control power supply of the walking mechanism through the controller; the amplitude limiter is used to prevent the operating platform from overturning due to excessive amplitude. When the amplitude exceeds the preset value, the amplitude limiter will cut off the control power supply of the lifting mechanism and / or walking mechanism through the controller to control the lifting and / or moving speed.

[0012] Furthermore, an anti-falling cover plate is installed at the docking window for opening and closing, which can improve the safety of use. When it is necessary to enter the manhole, the anti-falling cover plate can be opened.

[0013] Compared with the existing technology, the scissor-type hydraulic lifting tank truck inspection operation platform of the utility model is lifted and lowered and translated by operating the controller on the human-machine interactive panel, and the inspectors and inspection equipment are transported to the manhole on the top of the tank truck to be inspected. During the transportation process, the safety of the inspectors and ground staff is ensured by protective devices and alarm devices, avoiding the risk of falls or scratches when the inspectors climb to the high manholes, and providing a higher rated load to meet the inspectors' need to put sufficient inspection instruments and tools into work at the same time, thereby improving the efficiency of the inspection work.
