Embodiment Construction

[0024] see Figure 1-5 , the support frame 1 is a frame-type structure welded by rectangular tubes, and the walkway 3 is welded on the frame of the support frame 1 through the bracket, which is used to observe the operation of the equipment and maintain the equipment. There are two support seats 24 on the bottom surface of the support frame 1 for supporting the air bag 9 in the dynamometer 2. The middle structure of the support seat 24 has a column 23, which is used to cooperate with the notch of the connecting plate 7 in the dynamometer to prevent the connecting plate 7 rotate; there is a top drive mounting plate 25 on the upper left end of the support frame, which is used to install and fix the top drive 28; , air bag 9, water-cooled brake 8, etc.; there is a notch on the left and right sides of the connecting plate 7 near the middle part, which is used to cooperate with the column 23 to prevent the connecting plate 7 from rotating, and there is a circle of bolt holes in the...

Abstract

A dynamic torque online detection device includes a support frame, a walkway, and a dynamometer; wherein the support frame is used to install a top drive and a dynamometer, and the dynamometer includes: an output shaft, an input shaft, and a water-cooled brake. The top drive main shaft is connected, the lower end cooperates with the input shaft to transmit torque, the upper outer circle of the input shaft is equipped with a torque sensor, the input shaft cooperates with the water-cooled brake, and the water-cooled brake provides friction resistance torque, and the torque sensor tests the top drive torque and speed. The walkway is welded on the frame of the support frame through the bracket, which is used to observe the operation of the equipment and maintain the equipment. The present invention can detect the output power, torque and rotational speed of the top drive.

Description

technical field [0001] The invention belongs to the field of petroleum machinery, and particularly relates to a top drive performance detection device and a detection method. Background technique: [0002] The top drive device is a new type of drilling equipment used to replace the traditional rotary table-kelly drilling mode. It is a high-tech product integrating mechanics, electricity, hydraulics and communication. The top drive device directly transfers the drilling power from the turntable to the water tap, and the top directly drives the drilling tool to rotate and drill, without using the turntable and kelly. The top drive device can be used for vertical drilling; when it encounters resistance or sticking during the tripping process, it can be connected to the drill string at any height in the derrick to quickly establish circulation and rotate the drilling tool, and reverse reaming to pass the resistance, In case of sticking point, it can effectively prevent the occu...
