Specific embodiments

[0016] In the figure, the utility model is provided with a roller bed support 1, on which a conveying roller 2 and a pedal positioning pin sleeve are installed. A safety pedal 3 is installed on one side of the roller bed support 1, and a foundation pit 5 is provided outside the safety pedal 3. A hydraulic lifting platform 4 is installed in the foundation pit 5, and its function is to adjust the height of the shutter vehicle 6 to meet the height adaptability for the operator to stand on the safety pedal 3 and place the rubber parts. A guide rail support T1 is provided at the position of the safety pedal 3 and the roller bed support 1. The guide rail T2 and the sliding bearing T3 are fixed in the guide rail support T1. The sliding bearing T3 is connected to the folding and fixed safety pedal T4, and folding and telescopic safety pedal tracks T5 are provided on both sides of the folding and fixed safety pedal T4. The folding and telescopic safety pedal tracks T5 are connected to the folding and telescopic safety pedal T6 through folding and telescopic safety pedal pulleys T7. A multi-functional pedal positioning pin T8 capable of locking with the roller bed support 1 is installed on the folding and telescopic safety pedal T6. When the movable, telescopic, folding and multi-functional safety pedal is folded and stored, it is positioned and fixed with the roller bed support 1 through the multi-functional pedal positioning pin T8 to prevent the movable, telescopic, folding and multi-functional safety pedal from tipping over.

[0017] The specific operation plan is that before the production operation, the operator moves the telescopic foldable multifunctional safety pedal to fold and store it, and positions and fixes it with the roller bed bracket 1 through the multifunctional pedal positioning pin T8, raises the hydraulic lifting platform 4 to a pre-set position flush with the ground, ensures that the upper surface of the hydraulic lifting platform 4 is flush with the ground around the foundation pit 5, and uses a tractor to pull the louver car 6 to a designated suitable position on the hydraulic lifting platform 4, lifts up all the pages of the louver car 6, opens the multifunctional pedal positioning pin T8 of the mobile telescopic foldable multifunctional safety pedal and the roller bed bracket 1, uses the guide rail bracket T1 and the guide rail T2 as the origin support, and folds and fixes the safety pedal T4 and the foldable telescopic safety pedal T6 on the sliding shaft. With the support of bearing T3 and the guide rail T2 as the center, it is unfolded at a 90° angle and placed flat on the safety pedal 3. According to the length position of the louver car 6, the folding fixed safety pedal T4 and the folding telescopic safety pedal T6 are supported by the guide rail bracket T1 and the guide rail T2, and guided by the sliding bearing T3 for lateral movement and adjustment. According to the width of the louver car 6, the folding telescopic safety pedal T6 is supported by the folding telescopic safety pedal track T5 and the folding telescopic safety pedal pulley T7. The folding fixed safety pedal T4 and the folding telescopic safety pedal T6 are longitudinally separated until they reach a safe position suitable for operation. Then, the hydraulic lifting platform 4 is operated to raise the rubber component placement page and adjust it to a position slightly lower than the height of the conveying roller 2.Start the fast conveyor roller path of the production and transportation line, and transfer the extruded rubber component A to the conveyor roller 2 on the roller bed support 1. The operator stands on the telescopic folding multi-functional safety pedal that moves on both sides of the pallet truck 6, picks up and lifts the extruded rubber component A onto the bottom layer of the pallet truck 6 on the hydraulic lifting platform 4. After each layer is filled, stack them up one by one and lower the layers of the pallet truck 6 one by one. Since the height of the pallet truck 6 increases due to the gradual increase of the layers, and the maximum single weight of the rubber component reaches 50 Kg, it brings a certain burden to the operation. By adjusting the height of the hydraulic lifting platform 4 to gradually decrease, always keep the height of the placement layer of the pallet truck 6 slightly lower than the height of the conveyor roller 2, which provides convenience for the operator's inertial placement. After the rubber components are placed, operate the hydraulic lifting platform 4 to raise the pallet truck 6 to the pre-set position flush with the ground. Then, take the folding telescopic safety pedal T6 supported by the folding telescopic safety pedal track T5 and the folding telescopic safety pedal pulley T7 and longitudinally contract it in place. Using the guide rail support T1 and the guide rail T2 as the origin support, the folding fixed safety pedal T4 and the folding telescopic safety pedal T6 are folded at a 90° angle with the sliding bearing T3 as the support and the guide rail T2 as the center, perpendicular to the safety pedal 3. And with the guide rail support T1 and the guide rail T2 as the support and the sliding bearing T3 as the guide, move horizontally to adjust to the positioning position of the roller bed support 1, and fix the position with the roller bed support 1 through the multi-functional pedal positioning pin T8 to ensure safe storage. After that, use the tractor to tow the pallet truck 6 full of extruded rubber component A from the hydraulic lifting platform 4 to the designated storage area for storage. Repeat the above steps in sequence to give full play to the advantages of the mobile telescopic folding equipment, and completely eliminate the safety risk of the operator standing on the only 300-mm-wide footrest with a height difference, which is extremely prone to falling.
