Abstract

The utility model relates to a pressing wheel buffer mechanism of a cement layer lining machine and belongs to the technical field of metal casting. The pressing wheel buffer mechanism comprises a pressing wheel, a pressing wheel frame, a guide rod, a hydraulic cylinder, a support frame, a spring and a connecting rod, wherein the pressing wheel frame is connected with the pressing wheel through a shaft, the guide rod is arranged on the pressing wheel frame, the support frame is nested on the guide rod, the hydraulic cylinder is arranged at the center of the support frame, one end of the connecting rod is connected with the hydraulic cylinder, the other end of the connecting rod is connected with the pressing wheel frame, and the spring is nested on the connecting rod. The pressing wheel buffer mechanism has the advantages that the spring is adopted to be connected among the pressing wheel, the pressing wheel frame, the hydraulic cylinder and the support frame, the small-range vibration of a pressing wheel mechanism can be reduced through the spring buffer in the high-speed rotating process of a nodular cast iron pipe, and the wide-range vibration is only buffered through the vertical moving of a piston rod of the hydraulic cylinder, so the pressing wheel mechanism can be better in contact with the outer wall of the nodular cast iron pipe, and in addition, the service life of an oil cylinder is greatly prolonged.

Description

A kind of pinch roller damping mechanism of concrete lining machine
Technical field
The utility model belongs to the metal casting technical field, particularly a kind of pinch roller damping mechanism of concrete lining machine.
Background technique
The slush lining production technology of ductile iron pipe inner wall need be rotated pipe at a high speed, because ductile iron pipe has certain ovality, ductile iron pipe will produce bob when rotating at a high speed.Pressing wheel mechanism before is up and down buffering of piston rod that pinch roller relies on oil hydraulic cylinder.Because the impact force that the ductile iron pipe bob of high speed rotation produces is very big, oil hydraulic cylinder can not balance out this part impact force fully, thereby influences the working life of oil hydraulic cylinder, and the frequent maintenance of equipment has not only reduced productivity but also increased cost of production.
Summary of the invention
At the deficiency that prior art exists, the utility model provides a kind of pinch roller damping mechanism of concrete lining machine.
The technical solution of the utility model is achieved in that and comprises pinch roller, pinch roller frame, guide rod, oil hydraulic cylinder, supporting frame, spring and connecting rod; The pinch roller frame pinch roller that is coupling wherein, guide rod is installed on the pinch roller frame, and supporting frame is nested on the guide rod, and oil hydraulic cylinder is installed in the center of supporting frame, and connecting rod one end is connected with oil hydraulic cylinder, and the connecting rod the other end is connected with pinch roller frame, and spring is nested on the connecting rod.
Advantage of the present utility model: this mechanism adopts spring to connect between pinch roller, pinch roller frame and oil hydraulic cylinder, the supporting frame.Can be in ductile iron pipe high speed rotary course, make buffering by spring and reduce pressing wheel mechanism vibrations among a small circle, vibrations just rely on up and down buffering of piston rod of oil hydraulic cylinder on a large scale, pressing wheel mechanism can not only better contact with the ductile iron pipe outer wall like this, and prolonged the working life of oil cylinder greatly.
Description of drawings
Fig. 1 is the utility model structural representation;
Among the figure: 1 pinch roller, 2 pinch roller frames, 3 guide rods, 4 oil hydraulic cylinders, 5 supporting frames, 6 springs, 7 connecting rods.
Embodiment
Detailed construction of the present utility model is illustrated in conjunction with the embodiments.
As shown in Figure 1, comprise pinch roller 1, pinch roller frame 2, guide rod 3, oil hydraulic cylinder 4, supporting frame 5, spring 6 and connecting rod 7; Pinch roller frame 2 pinch roller 1 that is coupling wherein, guide rod 3 is installed on the pinch roller frame 2, and supporting frame 5 is nested on the guide rod 3, and oil hydraulic cylinder 4 is installed in the center of supporting frame 5, and connecting rod 7 one ends are connected with oil hydraulic cylinder 4, and the other end is connected with pinch roller frame 2, and spring 6 is nested on the connecting rod 7.
Working procedure of the present utility model: when cast tube is placed on the support roller, drives pinch roller 1, pinch roller frame 2 and guide rod 3 by oil hydraulic cylinder 4 and move down, after treating pinch roller 1 and the cast tube appearance contacting, oil hydraulic cylinder 4 stop motions.When support roller driving cast tube rotated at a high speed, the bob that the ellipse of cast tube produces, the jerk value motion of hour pinch roller 1, pinch roller frame 2 and guide rod 3 allowed spring 6 offset.The motion of pinch roller 1, pinch roller frame 2 and guide rod 3 allowed spring 6 and oil hydraulic cylinder 4 offset jointly when jerk value was big.Thereby reach the effect of protection oil hydraulic cylinder, also can make the better effects if of slush lining.
