[0020] To make the objectives, technical solutions, and advantages of this utility model clearer, the following detailed description is provided with reference to the accompanying drawings and preferred embodiments. However, it should be noted that many details listed in the specification are merely to provide the reader with a thorough understanding of one or more aspects of the utility model, and these aspects can be achieved even without these specific details.

[0021] Please see Figures 1 to 6 This utility model provides a vertically folding passageway, the technical solution of which is as follows:

[0022] The system includes a walkway panel, with a guardrail 3 on the side of the walkway panel. The guardrail 3 is inverted U-shaped and has two support rods 4 arranged vertically in sequence. The walkway panel is divided into a movable walkway panel 2 and a fixed walkway panel 1, and a connecting component is provided between the movable walkway panel 2 and the fixed walkway panel 1.

[0023] Existing mobile crushing and screening equipment is relatively high, requiring manual maintenance at its height. To facilitate maintenance personnel, passageways are usually installed. However, during some transportation and movement processes, the added passageways cause the overall width of the machine to exceed the required transport width, necessitating disassembly and reinstallation during use, which is time-consuming and labor-intensive.

[0024] By separating the aisle panel into a fixed aisle panel 1 and a movable aisle panel 2, which are hinged together and fixed by a connecting assembly, the movable aisle panel 2 can be rotated and bent downwards during movement, so that the movable aisle panel 2 forms a 90° angle with the fixed aisle panel 1, thereby reducing the width of the entire aisle and preventing the width of the entire equipment from being too large and affecting transportation. After reaching the designated position, the movable aisle panel 2 is rotated upwards around the hinge point using the connecting assembly and then fixed, completing the aisle assembly. This facilitates maintenance personnel to inspect the equipment, improves efficiency, and eliminates the need for lifting equipment, thus improving safety. The aisle does not occupy the space above it before or after folding, making it particularly suitable for situations where there are other components above the aisle.

[0025] The connecting assembly includes two fixed mounting plates 5 symmetrically arranged on both sides of the fixed aisle plate 1, and two movable mounting plates 6 symmetrically arranged on the left and right sides of the movable aisle plate 2. Each movable mounting plate 6 is hinged to the corresponding fixed mounting plate 5. Each fixed mounting plate 5 has a working hole 7 and a movable hole 8, and each movable mounting plate 6 has a working hole 9 and a movable hole 10. The working hole 9 and the movable hole 10 cooperate with the corresponding working hole 7 and the movable hole 8, and are fixed by a pin.

[0026] When in working condition, the fixed aisle plate 1 and the movable aisle plate 2 are in a horizontal state, that is, the working hole 7 on the fixed mounting plate 5 and the working hole 9 on the movable mounting plate 6 coincide. At this time, the pin is inserted into them to fix them. Multiple auxiliary holes are opened on the contact surfaces of the fixed aisle plate 1 and the movable aisle plate 2. The stability is enhanced by fixing with pins and other means and cooperating with multiple auxiliary holes.

[0027] When in transport mode, remove the pins in working hole 1 7 and working hole 2 9, remove the fixing means in multiple auxiliary holes, rotate downward with the hinge point as the center, so that movable hole 1 8 and movable hole 2 10 coincide, and then insert the pins into them. At this time, the fixed passageway plate 1 and movable passageway plate 2 are in a right-angle folded state, which reduces the lateral width and meets the transport size requirements.

[0028] The guardrail 3 and the walkway panel are detachably connected. The top of the movable walkway panel 2 away from the fixed walkway panel 1 is symmetrically provided with two corner brackets 11, and each corner bracket 11 is U-shaped. Both ends of the guardrail 3 are hinged to the corresponding corner bracket 11 by bolts. Each corner bracket 11 is provided with a fixing hole 12, and both ends of the guardrail 3 are provided with fixing holes 2 13 that cooperate with fixing holes 12. The movable walkway panel 2 is symmetrically provided with two fixing holes 3 14, and the support rod 4 is symmetrically provided with fixing holes 4 15 that cooperate with fixing holes 3 14.

[0029] In the working state, the fixing hole 12 on the corner bracket 11 and the fixing hole 13 on the guardrail 3 coincide, and are fixed by inserting a pin. At this time, the guardrail 3 is perpendicular to the walkway panel at 90°, which serves as a protective function. When in the transportation state, since the corner bracket 11 and the guardrail 3 are hinged by bolts, the pin between the fixing hole 12 and the fixing hole 13 is released, and the guardrail 3 is rotated to fit against the movable walkway panel 2. At this time, the fixing hole 14 and the fixing hole 15 coincide, and are fixed by inserting a pin. With the pins of the movable hole 8 and the movable hole 10 fixed, the entire walkway is in a right-angle folded state, which minimizes the lateral width, meets the size requirements for transportation, and improves convenience.

[0030] Each of the fixed mounting plates 5 has an L-shaped cross-section, which can be divided into a mounting part 501 and an extension part 502. The extension part 502 extends horizontally outward. It serves as a temporary foothold for maintenance personnel during the process of going up and down, providing them with a place to step on, helping them to obtain a stable support point during climbing or descending, making it easier to adjust their body posture and position, and reducing the risk of slipping or falling due to the lack of a suitable foothold to a certain extent, thus increasing safety during the process of going up and down.

[0031] All walkway panels are anti-slip plates, meaning that each walkway panel has multiple anti-slip holes 16. The anti-slip holes 16 increase the roughness of the panel surface, reducing the risk of slipping when personnel or equipment move on the panel, especially in wet, oily, or other slippery environments, thus improving safety. At the same time, during maintenance operations, if liquid is present, the anti-slip holes 16 can allow the liquid to drain quickly and debris to fall off in time, preventing water and debris accumulation, keeping the walkway panel surface clean, and further ensuring safe and smooth use.

[0032] Example 1: In operation, the working hole 7 of the fixed walkway plate 1 and the working hole 9 of the movable walkway plate 2 are coaxially fixed by pins, and the movable walkway plate 2 is fixed in a horizontal state, with the upper surface of the fixed walkway plate 1 coinciding with the upper surface of the movable walkway plate 2; the fixing hole 12 of the corner bracket 11 and the fixing hole 13 of the guardrail 3 are fixed by bolts, and the guardrail 3 is fixed in a vertical state, perpendicular to the movable walkway plate 2. The fixed walkway plate 1, the movable walkway plate 2, and the guardrail 3 form a safe working platform. By connecting several such working platforms in series, a safe walkway can be formed for operators to pass through or work, meeting the daily maintenance and repair needs of the mobile crushing and screening equipment.

[0033] Example 2: In the transportation state, the movable hole 8 of the fixed passageway 1 and the movable hole 10 of the movable passageway 2 are fixed coaxially by a pin, and the movable passageway 2 is fixed in a vertical state. The fixed hole 14 of the movable passageway 2 and the fixed hole 15 of the guardrail 3 are fixed by bolts, and the guardrail 3 is fixed in a vertical state. After two folding operations, the overall width of the passageway is reduced, thereby reducing the overall width of the mobile crushing and screening equipment to meet the transportation size requirements.

[0034] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
