[0014] Beneficial effects This invention provides a hydraulic steel formwork installation and dismantling device for the top and bottom formwork of the central drainage ditch in a tunnel, which has the following advantages compared with the prior art: 1. When the template is driven on the conveyor belt, the relevant technicians control the main shaft to start rotating, which in turn drives the worm gear A fixedly connected to both sides of the main shaft to rotate synchronously. The worm gear A drives the worm wheel A connected to it to rotate synchronously, which in turn drives the connecting rod fixedly connected to it to rotate synchronously. The connecting rod drives the eccentric wheel fixedly connected to the eccentric guide rod to rotate, which in turn drives the connecting rod A, which is rotatably connected to the eccentric guide rod, to start circular motion. The connecting rod A pushes the eccentric wheel connected to it to start rotating synchronously, which in turn drives the push rod connected to the eccentric part to start circular motion. The two push rods drive the hammer discs hinged to them to move linearly along the slide rail at the sliding connection with the shell. This causes multiple hammer discs to cooperate to start cyclically hammering the template, causing the hardened concrete on the template to detach. Simultaneously, when the main shaft rotates, it drives the worm gear B fixedly connected to it to start rotating synchronously. This causes the worm gear B to drive the worm wheel B meshing with it to start rotating in a circular motion. This causes the worm wheel B to drive the wheel axle fixedly connected to its axis to start rotating. This causes the wheel axle to drive the second eccentric wheel fixedly connected to its bottom to rotate synchronously. This causes the second eccentric wheel to drive the bottom rod fixedly connected to its bottom to rotate synchronously. This causes the bottom rod to drive the grinding rod fixedly connected to its bottom to start rotating. At the same time, when the second eccentric wheel rotates, it drives the connecting rod B rotating on it to start rotating in a circular motion. This causes the connecting rod B to drive the shaft disk rotating on it. This causes the shaft disk to drive the second grinding rod fixedly connected to its bottom to rotate. Thus, through the second grinding rod and the synchronous rotation of the grinding rod, the formwork is ground when the hammer disc hits the concrete on the formwork, so as to accelerate the concrete falling off the formwork. 2. When the main shaft rotates, it drives the pulley A fixedly connected to it to rotate synchronously. This causes the transmission rod to rotate synchronously with the pulley A under the cooperation of the second belt connected to it. This causes the transmission rod to drive the worm gear C fixedly connected to it to rotate synchronously. The worm gear C drives the worm wheel C meshing with it to start rotating synchronously. This causes the worm wheel C to drive the fan blade shaft fixedly connected to it to rotate synchronously. This causes the fan blade shaft to drive the fan blades fixedly connected to its bottom to rotate synchronously. This generates negative pressure air through the fan blades to blow away the gravel on the template. 3. The relevant technicians place the device in the drainage ditch and simultaneously control the device to begin linear movement in the ditch. This causes the inclined plate at the top of the casing to lift the template in the drainage ditch. As the device continues to move forward, the template falls into the inclined plate. At this point, the technicians control the roller shaft to start rotating, which in turn drives the first belt connected to it to rotate synchronously. The first belt then drives the second drum connected to it to rotate synchronously. The second drum then begins to transport the template through its hooks. Simultaneously, the technicians activate the rollers, so that when the template comes into contact with the rollers, the template begins to be transported through the cooperation of multiple rollers. When the template moves to... On the conveyor belt, the roller shaft drives the fixed rollers on it to rotate synchronously. With the cooperation of the two rollers, the conveyor belt connected to it begins to rotate, thus transporting the template. When the template reaches the end, it falls off. At this time, the roller shaft drives the third belt connected to it to rotate, which in turn drives the pulley C connected to it to rotate. The pulley C drives the shaft disc fixed at its center to rotate synchronously, which in turn drives the tie rod connected to its eccentric part to rotate synchronously. This causes the tie rod to push the punch plate hinged to it to move linearly along the slide rail connected to the housing. Thus, the template is re-nailing into the drainage ditch through the punch plate. Attached Figure Description

When the main shaft 209 rotates, it drives the worm gear B301 fixedly connected to it to rotate synchronously. This causes the worm gear B301 to drive the worm wheel B302 meshing with it to begin circular motion.
