Detailed Description

The present invention will be further described with reference to the following specific embodiments.

Example 1

Referring to fig. 1, the sliding mechanism for a flange separator of the present embodiment includes a sliding block 1, a driving shaft 2, and a guide block 3. Sliding block 1 have a cavity, drive shaft 2 and guide block 3 all are located this cavity, wherein, drive shaft 2 drives sliding block 1 and removes, guide block 3 along the axial free movement of drive shaft 2.

Specifically, in this embodiment, the driving shaft 2 is a piston rod, and the guide block 3 is sleeved on the piston rod. One end of the piston rod extends into the cavity of the sliding block 1 and is connected with the inner cavity wall of the sliding block 1; the other end is connected with an oil cylinder 8.

Specifically, as shown in fig. 2 to 4, the guide block 3 includes two protruding limiting claws 31, and the limiting claws 31 extend to the outer side of the sliding block 1. The sliding block 1 is provided with a first notch 11 for the limiting claw 31 to pass through, and a stop plate 12 is arranged on the side wall opposite to the first notch 11.

The connecting member 4 includes a connecting portion 41 and a sliding portion 42, wherein the sliding portion 42 is located in the first notch 11, the sliding portion 42 is limited in the first notch 11 by the stopper 12, and the sliding portion 42 can slide along the opening direction of the first notch 11.

In the sliding mechanism for a flange separator of the present embodiment, as shown in fig. 1, the inner cavity of the piston rod is provided with an elastic member 5, and the elastic member 5 stretches along with the extension of the piston rod. Specifically, in this embodiment, the elastic member 5 is a rectangular spring, and two ends of the rectangular spring are respectively connected to two ends of the inner cavity of the piston rod. During operation, the extension of piston rod drives the rectangle spring tensile, and when stopping, the tensile restoring force of spring drives the piston rod, and the piston rod drives sliding block 1 quick return to make the flange separator reset fast.

In the use process, the front end of the sliding block 1 needs to move towards the inside of the gap between the two flanges, so that parts between the flanges can be damaged, and the connecting effect of the flanges can be influenced. In order to solve this problem, the front end of the sliding block 1 is machined with a second notch 13, the second notch 13 is provided with a guide tongue 6, and the guide tongue 6 is detachably mounted in the second notch 13. The guide tongue 6 can be detached according to actual requirements to prevent the guide tongue 6 from causing parts between flanges.

Example 2

The flange separator of the embodiment comprises a movable block 7, an oil cylinder 8 and the sliding structure in the embodiment 1. Wherein, the movable block 7 is located the upper and lower both sides of sliding block 1, and the spacing claw 31 of guide block 3 is established to the movable block 7 cover. The connecting part 41 of the connecting piece 4 is connected with the movable block 7, the connecting piece 4 is arranged to ensure the stability of the connection between the sliding block 1 and the movable block 7, and the movable block 7 is guided and limited to move to ensure that the movable block 7 can be smoothly opened under the thrust action of the sliding block 1.

In operation, the cylinder 8 drives the piston rod to extend, and the slide block 1 slides forward under the thrust from the drive shaft 2. Since the connecting member 4 is connected to the movable block 7, the movable blocks 7 are pressed by the sliding block 1 to be opened away from each other. In the moving process of the movable block 7, the guide block 3 guides and limits the movement of the movable block 7. After the front end of the movable block 7 is stressed, the guide block 3 tensions and limits the rear end of the movable block 7, so that the rear end of the movable block 7 can be prevented from tilting to influence the separation effect.

Compared with the traditional flange separator, the flange separator adopts the action mode that the limiting pin is matched with the limiting groove, and the flange separator has small limitation on the moving distance of the movable block 7 by the guide block 3 and can separate the flange at a larger distance; in addition, because the guide block 3 is an integral piece, the moving stability of the movable block 7 is better in the working process; and the guide block 3 can bear larger tensile force, thereby improving the maximum tonnage of the whole pressing flange separator.
