Description

Technical Field

[0001] The utility model belongs to the technical field of compensators, and in particular relates to a rectangular compensator. Background Art

[0002] A compensator, also known as an expansion joint or telescopic joint, is a compensating element consisting of a bellows, end pipes, brackets, flanges, conduits, and other accessories. It utilizes the effective expansion and contraction of the bellows to absorb dimensional changes caused by thermal expansion and contraction in pipelines, conduits, and containers, or to compensate for axial, lateral, and angular displacements.

[0003] The current compensator needs to be equipped with a temporary restraint device (limit bolt) to prevent the compensator from being compressed and deformed before use. After use, the limit bolt usually needs to be removed and then placed in an external box to prepare for the maintenance of the compensator. This restraint method for the compensator cannot place the limit bolt on the compensator, and it is more troublesome to install the limit bolt in the box on the compensator every time it is inspected. In addition, the limit bolt model used for each model of compensator is also inconsistent, which makes it impossible for the staff to quickly and accurately install the bolt in the box on the compensator. Utility Model Content

[0007] Furthermore, the top of the limiting rod has a buckle, the interior of the connecting plate 1 has a slot corresponding to the buckle, the buckle and the slot are adapted to each other, and the limiting rod is detachably connected to the connecting plate 1 through the buckle and the slot.

[0008] Furthermore, a locking rod is horizontally arranged inside the limiting cylinder, and the locking rod passes through the limiting rod and the limiting cylinder and extends outward. A locking nut is provided on the side wall of the limiting cylinder, and the locking nut is threadedly connected to the locking rod.

[0009] Furthermore, the interior of the limiting rod has a first insertion hole and a second insertion hole, the second insertion hole is located below the first insertion hole, and the locking rod passes through the second insertion hole and penetrates the limiting rod.

[0010] Furthermore, the limiting cylinder passes through the second connecting plate and extends downward, and a nut is provided at the bottom of the second connecting plate, and the nut is threadedly connected to the limiting cylinder.

[0011] Compared with the prior art, the beneficial effects of the present invention are:

[0012] 1. By setting a limit device, when the rectangular compensator needs to be returned to the factory for inspection and maintenance, the locking rod can be pulled out from the second socket, and then the limit rod can be pulled upward until the buckle on the limit rod is inserted into the slot in the connecting plate. Then, the locking rod is inserted into the first socket and locked by the locking nut to complete the limitation of the bellows body. This device replaces the limit bolt with a limit device, avoiding the need to install the limit bolt in the box on the compensator every time it is returned to the factory for inspection.
