Technical Field

[0001] This invention relates to the field of safety island technology, and more particularly to a safety island boarding step structure. Background Technology

[0002] For safety island-style inspection channels, the height of the truck bed to be inspected is usually about one meter. Inspectors usually need to board the truck to inspect the goods. Currently, for boarding at the safety island in the inspection area, manual mobile boarding stairs are usually used. This method poses safety hazards when getting on and off the vehicle, and requires a lot of time for personnel to enter and exit, resulting in low work efficiency. Summary of the Invention

Like reference numerals denote like parts throughout the drawings. The drawings are not drawn to scale; their focus is on illustrating the gist of the invention.

[0020] Figure 2 This is a side view of the safety island boarding ramp structure in an embodiment of the present invention. Detailed Implementation

[0021] The present invention will be further described below with reference to the accompanying drawings and specific embodiments, but these are not intended to limit the scope of the invention.

[0022] like Figure 1 and 2As shown, this invention discloses a safety island boarding step structure. Specifically, the safety island boarding step structure includes: a gantry frame 2, a pulley system, a counterweight structure 5, and a step body 7. The tail of the step body 7 is rotatably fixed to one side of the safety island 1. The gantry frame 2 is fixedly installed on the upper surface of the safety island 1 corresponding to the step body 7. The gantry frame 2 includes two opposing columns and a crossbar located between the two columns. Each column is a hollow structure, and each column is provided with a pulley system and a counterweight structure 5. Each pulley system includes a fixed pulley 3 installed at the top of the column and a movable pulley 4 connected to the counterweight structure 5. A steel wire rope 6 is wound around each fixed pulley 3, and one end of the steel wire rope 6 is connected to the head of the step body 7, and the other end of the steel wire rope 6 passes around the movable pulley 4 and is fixed to the column. This pedal structure utilizes a steel wire rope 6 to transmit force between the counterweight structure 5 and the pedal body 7 via a pulley system. Specifically, the weight of the counterweight structure 5 and / or the head weight of the pedal body 7 can be adjusted according to actual site conditions to regulate the critical angle between the pedal body 7 and the gantry frame 2. When the angle between the pedal body 7 and the gantry frame 2 reaches a critical angle or higher, the pedal body 7 automatically descends under gravity. After descending to a 90° angle, the movable support 9 located below the pedal body 7 lifts it up. At this point, the counterweight structure 5 within the gantry frame 2 reaches its maximum lifting height. When the angle between the pedal body 7 and the gantry frame 2 is within the critical angle, the pedal body 7 automatically closes towards the gantry frame 2 under the traction force provided by the counterweight structure 5 via the steel wire rope 6, thus requiring no space when idle.

[0023] The safety island boarding ramp structure in this invention has two static states: closed and open. A lifting and lowering handle connected to a steel wire rope 6 can be installed on the upright of the portal frame 2, allowing external force to be applied to the steel wire rope 6 to control the opening and closing of the ramp body 7. Field tests showed that it can be opened and closed under a force of approximately 80KN (the conditions can be optimized by adjusting the material weight according to actual conditions). The opening and closing is relatively easy for an adult.

[0024] In a preferred embodiment of the present invention, the safety island 1 is provided with fixed structures 8 on both sides below the portal frame 2. The tail sides of the pedal body 7 are rotatably connected to the upper part of the fixed structure 8 by movable bolts. Specifically, each fixed structure 8 includes two oppositely arranged angle steels, and each angle steel includes a fixed plate and a connecting plate perpendicular to the fixed plate. The fixed plate is fixed to the side wall of the safety island 1 located on both sides below the portal frame 2 by fixed bolts. The two connecting plates are oppositely arranged, and bolt holes are provided at the upper and lower parts of each connecting plate. The bolt holes of the two connecting plates are correspondingly positioned. The movable bolt located at the tail of the pedal body 7 passes through the bolt holes located at the upper part of the two connecting plates. The pedal body 7 is provided with sliding grooves 71 on both sides, and movable supports 9 are provided on both sides of the bottom of the pedal body 7. One end of the movable support 9 is rotatably connected to the lower part of the fixed structure 8 by movable bolts (i.e., the movable bolt at the end of the movable support 9 passes through the bolt holes located at the lower part of the two connecting plates), and the other end of the movable support 9 is slidably connected to the sliding grooves 71 by sliders. When the slider slides to one end of the slide groove 71 near the head of the pedal body 7, the pedal body 7 is in a position perpendicular to the gantry body. At this time, the pedal structure is in an open state, so that the inspection personnel can climb onto the vehicle from the safety island 1, or climb onto the safety island 1 from the vehicle to be inspected.

[0025] In a preferred embodiment of the present invention, a stop structure (not shown in the figure) is fixedly provided inside the above-mentioned portal frame 2, and the stop structure is disposed between the movable pulley 4 and the counterweight structure 5. The stop structure is used to limit the counterweight block. When the stop structure limits the counterweight block, the pedal body 7 is perpendicular to the portal frame 2. Specifically, the stop structure is a baffle. When the angle between the pedal body 7 and the portal frame 2 reaches a critical angle or above, the pedal body 7 is automatically lowered by gravity. After it reaches a downward angle of 90° between the two, the lower movable support 9 lifts the pedal body 7. At this time, the counterweight structure 5 inside the portal frame 2 reaches the maximum lifting height. At this time, the upper surface of the counterweight structure 5 contacts the lower surface of the stop structure, and the stop structure limits the counterweight structure 5.

[0026] In a preferred embodiment of the present invention, the counterweight structure 5 includes at least one counterweight block, specifically, the counterweight block is a steel plate; thereby, the traction force of the counterweight structure 5 on the pedal body 7 can be adjusted by increasing or decreasing the number of counterweight blocks in the counterweight structure 5.

[0027] In a preferred embodiment of the present invention, the pedal body 7 is a steel grating; the gantry frame 2 is made of stainless steel, thereby making the pedal structure sturdy and durable.
