Problems solved by technology

[0002] The movement and installation of hydraulic power tongs is mostly achieved through suspension devices and push cylinders during drilling and workover operations. Due to the large size and heavy weight of the power tongs, many people are required to operate during the movement or installation process, and the labor intensity is high. Workers' safety factor is low
In addition, the space of some existing drilling platforms is narrow and unsuitable for installing suspension devices, which undoubtedly hinders the use of hydraulic power tongs

Abstract

The invention discloses a height-adjustable automatic reciprocating traveling power tongs device. The device comprises hydraulic power tongs which comprise a main tong and a back tong. The hydraulic power tongs are hung on a traveling support, and a traveling rail is laid at the bottom of the traveling support. The traveling support comprises an outer frame portion and an inner frame portion. The inner frame portion is connected with an outer frame portion through a hydraulic lifting unit and is capable of rising and descending along the inside of the outer frame portion. By means of the device, the device is moved front and back through the traveling support, the power tongs can rise and descend freely relative to a drilling table surface and can pass through the wellhead to a mouse hole opening, a cylinder and a suspension unit are not needed to be moved, the whole operation process can be completed through one person and can be completed through remote control, and accordingly, the labor intensity is reduced greatly, and the worker safety factor is improved.

Description

technical field [0001] The invention relates to a height-adjustable automatic reciprocating power tong device, which belongs to the field of petroleum drilling machinery. Background technique [0002] The movement and installation of hydraulic power tongs is mostly achieved through suspension devices and push cylinders during drilling and workover operations. Due to the large size and heavy weight of the power tongs, many people are required to operate during the movement or installation process, and the labor intensity is high. The safety factor of workers is low. In addition, some existing drilling platforms have narrow spaces and are not suitable for installing suspension devices, which undoubtedly hinders the use of hydraulic power tongs. Need a kind of new technical scheme to solve above-mentioned technical problem. Contents of the invention [0003] The purpose of the present invention is to provide a height-adjustable automatic reciprocating power tongs device, th...
