Problems solved by technology
[0003] However, there are still some disadvantages in the existing emergency anti-pull-off device with high safety. When the body of the anti-pull-off device is connected to the pipeline, the flange on the body of the anti-pull-off device and the flange on the pipeline cannot be kept in constant contact. Alignment state, so that there is a problem of water leakage at the connection; and when the body of the anti-pull-off device is connected to the external pipe, it may be affected by external factors and cause vibrations, which may cause damage to the components on the external pipe; and when After the main body of the anti-pull-off device is used for a long time, the surface of the anti-friction pad will be worn to a certain extent because the anti-friction pad is often in contact with the external pipe, and there is a problem that it is inconvenient to replace. Therefore, we propose a high-safety Emergency pull-off device

The invention discloses an emergency anti-pull-off device with high safety. The anti-pull-off device comprises an anti-pull-off device body, supporting frames are fixed to the surfaces of the two sides of the top end of the anti-pull-off device body. Through threaded grooves are formed in the surfaces of the two sides of the supporting frame, threaded push rods are connected to the inner sides ofthe threaded grooves in a threaded mode, the threaded push rods extend to the outer wall of the supporting frame, buffer frames are fixed to the tail ends of the threaded push rods, and buffer springswhich are evenly distributed are fixed to the surfaces of the inner sides of the buffer frames. By arranging the supporting frame, the anti-pull-off device body can be positioned and clamped when connected with an external pipeline, and aligned connection of the anti-pull-off device body and the external pipeline is guaranteed; through the arrangement of a buffer spring, vibration borne in the connecting process is buffered conveniently, the stability of connection between the anti-pull-off device body and an external pipeline is improved, and then the service life of the anti-pull-off devicebody and the service life of the external pipeline are prolonged; and through the arrangement of the plug pins, the anti-abrasion pad can be conveniently, rapidly and disassembled and replaced.
Description
technical field [0001] The invention relates to the technical field of pipeline compensators, in particular to an emergency pull-off prevention device with high safety. Background technique [0002] Pipeline compensators, also known as expanders or expansion joints, expansion joints, are mainly used to compensate for thermal expansion and contraction of pipelines caused by temperature changes. If the pipe is not completely free to expand or contract when the temperature changes, thermal stresses will develop in the pipe. This stress must be considered in the pipeline design, otherwise it may cause the rupture of the pipeline and affect the normal production. As an important part of pipeline engineering, compensators play an important role in ensuring the long-term normal operation of pipelines. [0003] However, there are still some disadvantages in the existing emergency anti-pull-off device with high safety. When the body of the anti-pull-off device is connected to the p...
