Description

Device for limiting shaking of clamping screw of large plate heat exchanger

Technical Field

The utility model belongs to the technical field of the screw rod fastening, especially, relate to a device of tight screw rod shake of restriction large-scale plate heat exchanger clamp.

Background

In recent years, a single large-load plate heat exchanger is applied more and more widely, a detachable maintenance space or a later-stage plate adding space is reserved due to equipment, a clamping screw is often very long, the rear part of the clamping screw is in a non-support state in the whole assembly state of the equipment, the self rigidity is completely relied on, the screw can shake in the transportation and normal operation states of the equipment, the screw can collide with each other seriously and even, and hidden dangers exist in the operation and subsequent maintenance of the equipment.

SUMMERY OF THE UTILITY MODEL

Therefore, the utility model provides a device of tight screw rod shake of restriction large-scale plate heat exchanger clamp for overcome the problem of screw rod shake among the prior art.

The utility model provides a device of the tight screw rod shake of restriction large-scale plate heat exchanger clamp, the device comprises a plurality of connection pieces and a plurality of nut, wherein:

the connecting piece penetrates through one end, close to the strut, of the clamping screw rod and is used for fixing the clamping screw rod in a specified range;

the nut is arranged on the clamping screw rod and used for fixing the connecting piece.

Furthermore, two ends of the connecting sheet are respectively provided with a round hole.

Compared with the prior art, the utility model adopts the screw rod connection and the vibration-proof plate at the tail part of the clamping screw rod, so as to stabilize each clamping screw rod, thus leading the clamping screw rods to be more stable and ensuring the operation safety and reliability of the equipment; under the restriction of the interaction between the connecting piece and the screw rod, the problem of single free shaking can be effectively overcome.

Particularly, the vibration-proof plate can effectively prevent the phenomenon that the clamping screw shakes, and ensure the safety and reliability of the operation of the equipment.

Especially, the nut can effectually be fixed the connection piece has promoted the stability of vibration damper.
