[0002] The publication number is CN202829431U "an adjustable pipeline lifting device". This device uses columns and beams as supports to realize the lifting of the pipeline through the transmission system. The upper and lower columns are matched by flanges to adjust the height of the device. In the actual working conditions of the subsidence area, the temporary manual assembly of the upper and lower columns takes a long time and the efficiency is low, and the emergency response to the goaf subsidence area cannot be carried out in time. When the actual working conditions require a large width of the device, the width of the device cannot be adjusted, and the adjustable type The pipeline lifting device adopts the motor as the power source, which can realize the lifting of the pipeline, but the lifting speed of the device is unique, and it is difficult to meet the requirements of the pipeline lifting speed in the goaf subsidence area. Therefore, designing a two-speed straightening device can not only meet the lifting speed Operation requirements, and the device can be adjusted in width and height to meet the needs of different field operations

Embodiment Construction

[0027] The specific embodiments of the present invention will be further described below in conjunction with the accompanying drawings.

[0028] Implementation of the present invention provides a gantry-type double-speed emergency correction device for oil and gas transmission pipelines in goaf subsidence areas. The gantry-type double-speed emergency correction device includes a transmission system, a beam assembly and a column assembly; its overall structure is in The channel steel guide rail in the beam assembly 2 is equipped with a transmission system 1, and the beam assembly 2 is set as a gantry structure by the support frame of the column assembly 3, so that the overall structure constitutes a double-speed emergency correction device for oil and gas pipelines.

[0029] In the transmission system 1, the lifting sensing gear 25 is connected with an encoder coupling 24 and an encoder 31 thereof; the slow synchronous motor 29 is installed behind the motor mounting frame 18, an...

Abstract

The invention discloses a gantry-type double-speed emergency correction device for a mined-out collapse area oil-gas transmission pipeline. The device is characterized in that a low-speed motor and ahigh-speed motor provide power, through a bidirectional overrunning chain wheel assembly mechanism, the power is transferred to a hoist assembly, after the hoist assembly reduces speed, hoisting workis conducted on a lifted object, and meanwhile, an encoder for detecting the height of the lifted object is installed, so that double-speed lifting is achieved, and the stationarity of the lifted object and high efficiency of a lifting system are guaranteed.

Description

technical field [0001] The invention relates to a straightening device for an oil and gas transmission pipeline in a goaf subsidence area, in particular to a two-speed straightening device for improving emergency treatment of an oil and gas transmission pipeline in a goaf subsidence area. Background technique [0002] The publication number is CN202829431U "an adjustable pipeline lifting device". This device uses columns and beams as supports to realize the lifting of the pipeline through the transmission system. The upper and lower columns are matched by flanges to adjust the height of the device. In the actual working conditions of the subsidence area, the temporary manual assembly of the upper and lower columns takes a long time and the efficiency is low, and the emergency response to the goaf subsidence area cannot be carried out in time. When the actual working conditions require a large width of the device, the width of the device cannot be adjusted, and the adjustable ...
