Technical Field

The utility model belongs to the technical field of pressure vessel manufacturing, and particularly relates to a small-caliber pressure tank inner wall cleaning tool.

Background

The pressure vessel is generally of tubular construction as shown in figure 4 and its port is generally of small diameter in order to ensure adequate pressure-resistance and sealing. When the pressure container is manufactured, the arc seats at two ends and the tank body part at the middle section are generally manufactured separately and then are connected by welding, which inevitably causes welding slag and dust on the inner wall of the tank body during welding. The conventional pressure flushing is difficult to thoroughly remove the welding slag on the inner wall of the tank body, and once the welding slag falls off in the using process in the production period, the welding slag can easily enter pipelines and various valve bodies to cause the blockage of the pipelines or the valves.

In the description of the present invention, it should also be noted that, unless otherwise explicitly specified or limited, the terms "disposed," "mounted," "connected," and "connected" are to be construed broadly, e.g., as meaning either a fixed connection, a removable connection, or an integral connection; either directly or indirectly through intervening media, or through both elements. The specific meanings of the above terms in the present invention can be understood by those skilled in the art according to specific situations.

As shown in fig. 1 and 3, a cleaning tool for the inner wall of a small-bore pressure tank comprises: extension rod 1, slip ring 2, connecting block 3 and brush head 4.

Specifically, the outer wall of the long cylindrical structure of the extension rod 1 is provided with a sliding groove 11 along the axis direction, and a plurality of grooves are arranged along the circumference of the extension rod 1.

Specifically, the slip ring 2 is slidably sleeved on the outer side of the extension rod 1, and the slip ring 2 is provided with a locking screw 21 in a penetrating manner for fixing the position of the slip ring 2 on the extension rod 1. And the front end of the locking screw 21 is provided in the slide groove 11 to prevent the sliding ring 2 from rotating.

Specifically, two ends of the connecting block 3 are hinged with connecting rods 31, wherein the connecting rod 31 at one end is hinged at the front end of the extension rod 1, and the other connecting rod 31 is hinged with the sliding ring 2. By moving the sliding ring 2 on the extension rod 1, the connecting block 3 can be movably arranged along the normal direction of the extension rod 1 so as to change the overall external contour dimension of the tool.

Preferably, each sliding groove 11 corresponding to the outer wall of the extension rod 1 is provided with a connecting block 3, and the connecting block 3 is respectively connected with the extension rod 1 and the sliding ring 2 through connecting rods 31 at two ends.

The brush head 4 is arranged on the outer wall of the connecting block 3.

Preferably, the sliding blocks 12 are arranged in the sliding grooves 11 in a sliding mode, the sliding blocks 12 are connected with the connecting blocks 3 through the elastic elements 5, and when the elastic elements 5 are in a natural state, the distance between the connecting blocks 3 and the extension rod 1 is the minimum.

The connection position of the elastic member 5 and the connection block 3 is closer to the extension rod 1 than the hinge position of the connection block 3 at both ends. Utilize elastic element 5 taut with connecting block 3 to the direction of extension rod 1, slider 12 also slides in spout 11 along with one simultaneously, make elastic element 5 perpendicular to extension rod 1 all the time, the supporting resistance who utilizes connecting block 3 both ends connecting rod 31 to provide in addition, elastic element 5 perpendicular to connecting block 3, and make connecting block 3 be on a parallel with extension rod 1, so that brush head 4 is on a parallel with extension rod 1, also be on a parallel with the axis of the jar body simultaneously, the brush body 4 that makes is laminated inseparabler with the inner wall of the jar body.
