Description

Technical Field

[0001] The utility model relates to the field of accumulator assembly auxiliary tools, and specifically relates to an auxiliary device for installing a bladder. Background Technique

[0002] Bladder accumulators have been widely used in the hydraulic and fluid industries due to their own advantages. A bladder accumulator consists of two parts: an oil side and a gas side. The bladder, as an element that isolates the two parts, plays an extremely important role. To ensure that the bladder is not damaged during assembly, it is very necessary to use a special and labor-saving installation device.

[0003] During the installation process, it is required that the bladder cannot be twisted. For accumulators with a small nominal volume, the shell length is short and the installation is relatively easy; however, for accumulators with a larger nominal volume, the shell length becomes longer and the installation becomes more difficult. For accumulators with a larger volume, installing the bladder relies on the personal experience of workers and requires two people to cooperate to complete. Therefore, it is necessary to use installation tools to reduce the installation time and save manpower. Content of the Utility Model

[0005] To achieve the above purpose, the utility model provides the following technical solution: an auxiliary device for installing a bladder, including a connection joint, a universal joint, a connecting rod, and a handle. The connecting rod is in an overall strip structure. One end of the connecting rod is connected to the universal joint. The universal joint is rotatably connected to the connection joint. The connection joint is fixedly connected to the bladder used in the accumulator. The other end of the connecting rod is connected to the handle.

[0006] Preferably, the universal joint is a single-section round-hole type universal joint. Symmetric brackets are arranged at one end of the universal joint connected to the connection joint. One end of the connection joint is clamped between the symmetric brackets and connected by a rotating shaft.

[0007] Preferably, a connection bolt is arranged at one end of the connecting rod, and a connection screw hole is arranged at the other end. The connection bolt and the connection screw hole are arranged in a matching manner. The connection bolt is clamped into the universal joint and fixed by a screw on the side of the universal joint. A connection screw rod is arranged on the handle, and the connection screw rod is connected to the connection screw hole on the connecting rod.

[0008] Preferably, the connection joint is threadedly connected to the bladder used in the accumulator, and the handle is set in a T shape.
