[0021] The giant tire molding machine is equipped with a machine base Z1. A foundation pit Z2 with a width of about 3 meters and a depth of 1.5 meters is formed between the two machine bases Z1. Two parallel guide rails Z3 are installed above the machine base Z1. Slide bearings Z4 are arranged on the guide rails Z3 and are connected to the moving transfer ring Z6 through a connecting seat Z5. Driven by an external force, the transfer ring Z6 makes a linear reciprocating motion on the guide rails Z3 of the machine base Z1.
[0022] In the figure, the utility model is provided with a bottom plate T1 on the side of the rear pressure device of the main machine of the molding machine, and a set of telescopic large-span safety bridge pedals that can be driven by a brake motor to have a telescopic function and can be accurately positioned are installed above the bottom plate T1. Two rows of 6 guide rail support seats T2 are installed in parallel above the bottom plate T1, and two cylindrical guide rails T3 are fixed on the guide rail support seats T2. Two sets of linear bearings T4 with fixed seats are respectively installed on the two cylindrical guide rails T3, which are connected to the telescopic movable pedal T5 through the fixed seats of the linear bearings T4. A brake drive motor T6 is installed in the middle of the rear, and a drive synchronous pulley T7 is installed on the output shaft of the brake drive motor T6. A set of fixed synchronous pulleys T8 is provided in the middle of the front half of the base plate T1. The drive synchronous pulley T7 and the fixed synchronous pulley T8 are connected by driving synchronous belt T9, and the drive synchronous belt fixing card T10 is connected to the drive synchronous belt T9 at the middle position of the rear end of the telescopic moving pedal T5, so that the motor rotates in the forward and reverse directions to drive the telescopic linear motion of the telescopic moving pedal T5, thereby connecting the front and rear of the main machine. The surface of the telescopic movable pedal T5 is provided with an anti-skid pedal, and safety guardrails T11 are added on both sides to provide safety, anti-skid and anti-fall protection. A set of T-shaped supporting wheels T12 are respectively provided on both sides in front of the bottom plate T1 and the telescopic movable pedal T5. While supporting the telescopic movable pedal T5 to move linearly, it plays a role in lateral positioning of the telescopic movable pedal to ensure the positioning accuracy of the telescopic movable pedal. A set of position-adjustable pedal extension detection switch T13 and pedal retraction detection switch T15 are respectively installed at the rear end of the bottom plate T1 and the middle guide support seat T2. The pedal extension detection switch T13 and the pedal retraction detection switch T15 are connected to the molding The telescopic moving pedal T5 is connected to the PLC of the machine. When the pedal is extended to the position detection switch T13, the moving devices on the equipment base Z1 are all in the shutdown state, and the positioning safety locks T14 on both sides of the front end of the telescopic moving pedal T5 are triggered. When the pedal is retracted to the position detection switch signal T15, the moving devices on the equipment base Z1 can be restored to the running state, which plays a role of safety interlock protection. A set of mobile control edge airbag safety switches T16 are respectively installed at the front and rear ends of the telescopic moving pedal T5 to ensure safety during operation. Once the mobile control edge airbag safety switch T16 is triggered, the brake drive motor stops immediately and the telescopic moving pedal T5 is controlled in a static state. A set of positioning safety locks T14 are respectively installed on both sides of the front end of the telescopic moving pedal. After the telescopic moving pedal is extended to the position, it is retracted and positioned, and the extension height of the positioning safety lock is adjusted according to the height of the telescopic moving pedal, which not only completes the positioning but also meets the support function of the front and rear height consistency of the telescopic moving pedal, reducing the far end tilting deviation force of the linear bearing.
[0023] The specific operation plan is as follows: during normal production, when an abnormality occurs behind the equipment and the operator needs to go to the rear of the equipment for abnormality handling, switch the automatic switch on the operation panel to the manual position, operate the button, and drive the transfer ring Z6 under the drive of the slider bearing Z4 and the connecting seat Z5 on the two parallel guide rails Z3 of the machine base Z1 and the external force. The transfer ring Z6 is moved from the working position A-1 of the transfer ring of the molding machine to the waiting position A-2 of the transfer ring of the molding machine, cut off and lock the main machine emergency stop button, and hang a warning sign. Manually operate the extension control button of the telescopic large-span safety crossing pedal. The telescopic moving pedal T5, the positioning safety lock T14, the safety guardrail T11, and the moving control edge airbag safety switch T16 are driven by the braking drive motor T6 to drive the synchronous belt T9 to drive the drive synchronous belt pulley T7 and the fixed synchronous belt pulley T8 with the drive synchronous belt fixing clip T10 as the drive point to perform the extension movement. Under the action of the two cylindrical guide rails T3 supported by the 6 guide rail supports T2 above the bottom plate T1, the linear bearing T4 with a fixed seat, and the T-shaped supporting wheel T12, the smooth linear movement of the telescopic large-span safety crossing pedal is ensured. When the extension reaches the signal output of the pedal extension in-place detection switch T13, the positioning safety lock T14 automatically extends and positions. The operator enters the telescopic moving pedal T5 and, under the safety protection of the safety guardrail T11, smoothly goes from the front of the equipment to the rear of the equipment for emergency handling. Due to the signal output of the pedal extension in-place detection switch T13 and the cutting off and locking of the main machine emergency stop button, double protection is provided to restrict the movement of the transfer ring Z6 on the equipment base Z1, effectively ensuring the safety of the operator during the crossing process. When the abnormal handling at the rear is completed, the operator enters the telescopic moving pedal T5 in the reverse direction and, under the safety protection of the safety guardrail T11, smoothly returns from the rear of the equipment to the front of the equipment. Manually operate the retraction control button of the telescopic large-span safety crossing pedal. After the positioning safety lock T14 automatically opens, the braking drive motor T6 rotates in reverse to drive the telescopic large-span safety crossing pedal to retract. When the telescopic moving pedal T5 retracts and touches the signal T15 output of the pedal retraction in-place detection switch, the safety protection that restricts the movement of the transfer ring Z6 on the equipment base Z1 is unlocked. During the extension or retraction of the telescopic large-span safety crossing pedal, if the moving control edge airbag safety switch T16 is triggered by touching an obstacle, the signal output automatically controls the braking drive motor T6 to perform an emergency braking stop, playing a role in mobile safety protection. After the above operations are completed, after confirming the on-site safety, unlock the main machine emergency stop button, remove the warning sign, switch the switch on the operation panel from the manual position to the automatic position, and start the automatic start button to control the equipment to perform the next cycle of operations. If a similar situation occurs again, repeat the above operations.The operator does not need to walk around the forming equipment with a length of about 50 meters and a width of about 30 meters throughout the process, solving the potential safety risk of falling when forced to cross through the middle of the equipment, where the equipment frame has a span of nearly 3 meters and a depth of 1.5 meters. At the same time, it reduces the large amount of time wasted by the traditional operation of walking around the equipment from both sides of the forming machine to the rear for processing, improves work efficiency, and enables timely emergency treatment to eliminate potential safety risks.
