The present invention uses one electric cylinder instead of three sets of double-cylinder ejector devices to assist the back and forth transport of drill pipes. Three sets of double-cylinders require six hydraulic cylinders to work synchronously, which is difficult to meet the requirements of operational stability and synchronization. With the increasing work intensity of modern oil drilling With the improvement of the degree of automation, it is necessary to develop equipment with high efficiency, low power consumption and simple maintenance to complete the transfer of drill pipes between the pipe rack and the conveying equipment

Embodiment Construction
[0014] like figure 1 , a general layout diagram of a two-pivot rotary drill pipe turning device including a base 2 and a turning device 3; Installation, the main work of this mechanism is to turn the drill pipe 1 from the pipe rack 4 into the V-shaped groove 6 of the base, or transport it in reverse. The base 2 is mainly a steel truss structure, which is used to support and transport the drill pipe 1, and at the same time provide space for the installation of the rod turning device 3. Both sides of the upper surface of the base 2 are flat steel plates, and there are three long slots 5 on each side, which are convenient for the embedment and installation of the turning frame 12 in the turning device 3; the middle of the base 2 is a V-shaped groove 6 structure, which is used for the drill pipe Stable for short periods of time.
[0015] like figure 2 , The bar turning device 3 includes an electric cylinder 8 , a rotary joint 10 , a supporting steel plate 13 and a turning fram...

The invention discloses a two-fulcrum rotating type drill rod overturning and conveying mechanism. The mechanism adopts two sets of wide-mouth clamping grooves for two-point supporting and a single electric cylinder for driving an integrated overturning frame. The total composition of the mechanism comprises a base and rod overturning devices. Two sides of the base are in contact with a pipe rack. The two rod-overturning devices are arranged on two sides of the base symmetrically. The main work of the mechanism is to complete the reciprocating conveying that a drill rod is overturned from the pipe rack to a V-shaped groove in the base. The linear conveying in the V-shaped groove and the conveying of pushing out of the V-shaped groove are completed by other devices. The transmission of the straight and the V-groove in the tank is carried out by other devices. According to the two-fulcrum rotating type drill rod overturning and conveying mechanism, the mechanism is mainly used for transporting columns in the automatic drilling, the whole mechanism is simple in structure, one electric cylinder replaces six hydraulic cylinders, column conveying procedures are simplified, and the conveying efficiency of the columns is improved.
Description
technical field [0001] The invention relates to the field of oil drilling drilling tool transportation, and is a mechanism for automatically conveying drill pipes from the base plane between the ground pipe rack and the conveying equipment. Background technique [0002] During oil drilling operations, it is often necessary to transport drill pipes back and forth between the drilling tool storage area and the drilling platform. The transfer of drill pipe between the pipe rack and the conveying equipment requires corresponding auxiliary automation facilities or manual operation. The present invention uses one electric cylinder instead of three sets of double-cylinder ejector devices to assist the back and forth transport of drill pipes. Three sets of double-cylinders require six hydraulic cylinders to work synchronously, which is difficult to meet the requirements of operational stability and synchronization. With the increasing work intensity of modern oil drilling With the ...
