A pipeline limiting device with anti-stuck function

Abstract

The present invention discloses a pipeline limiting device with an anti-stuck function, wherein a spring base is evenly fixed on the inner side of the limiting frame beam along the circumferential direction, and a spring top seat is fixed on the outer side of the movable beam, and one spring base corresponds to a spring top seat and a cylindrical coil spring, wherein one end of the cylindrical coil spring is located in the corresponding spring base, and the other end of the cylindrical coil spring is inserted into the corresponding spring top seat; the movable beam is distributed in sequence along the circumferential direction, and the top and bottom surfaces of the limiting frame beam are respectively provided with a first clamping block and a second clamping block, and the top and bottom surfaces of the movable beam are respectively provided with a first support and a second support, and the first clamping block is in plane contact with the first support, and the second clamping block is in plane contact with the second support; a tensioning device is provided on the outer side of both ends of the movable beam, and the device has the characteristics that no jamming occurs between the limiting pipe clamp and the limiting plate, and the friction force in the non-limiting direction is controllable.
