When the warning board winding and unwinding system is used, the piston rod of the oil cylinder hydraulic cylinder 1 is pushed out to jack the movable pulley mechanism 2, one end of the chain 3 matched with the movable pulley mechanism is fixedly connected, the other end of the chain is connected with the lifting support plate 5, and the lifting support plate 5 is driven by the adjustable roller bearing 6 arranged on the lifting portal frame 1 to move up and down, so that the placement and the recovery of the anti-collision wall and the warning board are realized.
In summary, the following steps: the lifting movement of the lifting support plate is realized by adding a transmission chain and a movable pulley mechanism on the lifting hydraulic cylinder. According to the transmission principle, the stroke of the lifting hydraulic cylinder is shortened by half by adopting a transmission mechanism combining the lifting hydraulic cylinder, a chain and a movable pulley. The transmission chain is fixed at one end of the lifting portal frame, the stroke of a piston of the lifting hydraulic cylinder is shortened by a half, but the acting force borne by the lifting hydraulic cylinder is required to be 2 times of the original acting force.
For a lifting working device, a lifting hydraulic cylinder needs to output acting force when lifting a heavy object, and a lifting support plate is lowered to the bottom when putting down the heavy object, so that the lifting system adopts a differential connection mode of a single-action hydraulic cylinder, and in order to prevent the lifting hydraulic cylinder from freely falling due to the heavy object and simultaneously play the purpose of speed regulation, a back pressure element is required to be arranged in an oil return path of the lifting system for one time to prevent the heavy object and the lifting support plate from overspeed lowering due to self weight, and a balance loop is formed.
In this design application, the sprocket only acts as a motion force transmitter. The fit relationship of the bearings is a base shaft fit, and because of the large stresses experienced, the selected tolerance is determined to be U7/h 6. The bearing chain wheel does not need to be provided with wheel teeth, the middle of the structure of the bearing chain wheel is provided with a smooth cam, and the chain wheel only needs to push against a roller in the middle of a roller chain to rotate. The sprocket is required to have sufficient strength and wear resistance, so that the sprocket boss surface is heat-treated to have a certain hardness.
The present invention is not limited to the above preferred embodiments, and any person can obtain other products in various forms without departing from the scope of the present invention, but any change in shape or structure is within the scope of protection.
