Furthermore, the terms "first" and "second" are used for descriptive purposes only and are not to be construed as indicating or implying relative importance.

In the description of the present invention, it is to be noted that, unless otherwise explicitly specified or limited, the terms "mounted," "disposed," "connected," and the like are to be construed broadly, such as "connected," which may be fixedly connected, detachably connected, or integrally connected; can be mechanically or electrically connected; they may be connected directly or indirectly through intervening media, or they may be interconnected between two elements. The specific meanings of the above terms in the present invention can be understood in specific cases to those skilled in the art.

The flexible supporting device for the inlet and outlet material pipe lines of the liquid ammonia storage tank comprises a mounting seat 1; a clamp 2 for fixing a pipeline is arranged above the mounting seat 1; two sides of the mounting seat 1 are hinged with sliding plates 3; one end of the sliding plate 3 is hinged with the mounting seat 1 through a rotating shaft pin 5; the other end of the sliding plate 3 is provided with a sliding chute 12; the sliding chute 12 is of an arc-shaped structure, and a clamping shaft 6 is embedded in the sliding chute; one end of the clamping shaft 6 is connected with the mounting seat 1, and the other end of the clamping shaft 6 is provided with a connecting plate 7; a base 4 is arranged below the mounting seat 1; a supporting pressure spring 11 is arranged between the mounting seat 1 and the base 4; and an adjusting pressure spring 8 is arranged between the connecting plate 7 and the base 4.

The connecting plate 7 is provided with an opening; an adjusting screw rod 9 is arranged in the opening; the inner diameter of the opening is larger than the outer diameter of the adjusting screw rod 9; the lower end of the adjusting screw rod 9 is fixedly connected with the base 4; and an adjusting nut 10 is arranged on the adjusting screw rod 9 above the connecting plate 7. The outer diameter of the adjusting nut 10 is larger than the inner diameter of the opening. The height adjustment of the adjusting pressure spring 8 is realized by rotating the adjusting nut 10.

The clamping shaft 6 is rotatably connected with the connecting plate 7. The clamping shaft 6 is provided with ring platforms at two sides of the sliding groove 12. The force stability of the connecting plate 7 and the adjusting nut 10 is ensured by the rotary connection.

The sliding plate 3 is of an arc-shaped fan plate structure; the rotating shaft pin 5 is positioned at the position of the center of a circle of the arc-shaped fan plate structure.

The number of the supporting compression springs 11 is 2, and the supporting compression springs are symmetrically distributed between the mounting seat 1 and the base 4.

The hoop 2 is fixed above the mounting seat 1 through bolts.

The working principle is as follows:

as shown in fig. 4, the one end that is located rotatory pivot 5 is the one end that meets with liquid ammonia storage tank discrepancy feed pipe, after the liquid ammonia storage tank is full of the medium, because the change of jar body weight to lead to the jar body to take place to subside, the one end that is located rotatory pivot 5 discrepancy feed pipe receives decurrent pulling force, thereby leads to the discrepancy feed pipe to take place to deform, the easy problem of revealing that appears.

Therefore, firstly, impact force when the liquid ammonia storage tank subsides is effectively slowed down through supporting pressure spring 11, secondly, after liquid ammonia storage tank position is relatively stable, through rotatory adjusting nut 10 for adjust pressure spring 8 and carry out the height adjustment, guarantee that mount pad 1 and connecting plate 7 are in relative horizontality.

It should be noted that, at the in-process of this equipment of first installation, when the liquid ammonia storage tank does not take place to subside, need to guarantee that mount pad 1 and connecting plate 7 are in same water flat line state to guarantee when the liquid ammonia storage tank takes place to subside the back, can audio-visual discovery mount pad 1 and connecting plate 7 the deviation appears, and carry out timely effectual regulation through rotation adjusting nut 10.

The inner diameter of the opening on the connecting plate 7 is larger than the outer diameter of the adjusting screw rod 9, and the sliding groove 12 is of an arc-shaped structure, so that enough adjusting space is ensured to ensure the normal use of the device.

It will be evident to those skilled in the art that the invention is not limited to the details of the foregoing illustrative embodiments, and that the present invention may be embodied in other specific forms without departing from the spirit or essential attributes thereof.
