Embodiment Construction

[0031] Below in conjunction with accompanying drawing, the present invention is described in detail.

[0032] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0033] Such as Figure 3 to Figure 10 A new injection head 2 gooseneck 1 follow-up mechanism shown includes a gooseneck 1 and an injection head 2, a rotary device 3 is provided between the gooseneck 1 and the injection head 2, and the gooseneck 1 and the injection head 2 The injection head 2 is rotatably connected by the rotary device 3 . The gooseneck 1 is rotated on the injection head 2 through the rotary device 3, and the coiled tube 4 enters the gooseneck 1 from the drum 5. When the coiled t...

Abstract

The invention relates to the technical field of drilling equipment, in particular to a novel injection head gooseneck servo mechanism. The mechanism comprises a gooseneck and an injection head, wherein a rotary device is arranged between the gooseneck and the injection head, and the gooseneck and the injection head are connected in a rotary mode through the rotary device. The gooseneck is arranged on the injection head in a rotary mode through the rotary device, a coiled tubing enters the gooseneck through a roller, the gooseneck rotates under the drawing of the coiled tubing when the coiled tubing is not at the center position, and then the gooseneck can move along with the coiled tubing, the coiled tubing is prevented from bending when the coiled tubing enters the gooseneck, and the service life of the coiled tubing is prolonged; furthermore, due to the fact that the gooseneck is not provided with a horn mouth structure, overall arrangement of a coiled tubing operation machine is not limited.

Description

technical field [0001] The invention relates to the technical field of drilling equipment, in particular to a novel injection head gooseneck follow-up mechanism. Background technique [0002] Coiled tubing machines are widely used in drilling construction. At present, the injection head gooseneck structure used on coiled tubing machines (such as figure 1 shown), it mainly includes a gooseneck 1 and an injection head 2, the gooseneck 1 is fixedly arranged on the injection head 2, and when in use, the coiled tubing 4 wound on the drum 5 of the coiled tubing machine first passes through the gooseneck 1 Then enter the injection head 2. [0003] The injection head gooseneck structure of this structure has the following disadvantages: [0004] First, since the drum 5 has a certain width, when the coiled tube 4 enters the gooseneck 1 around the drum 5, there is a certain displacement along the width direction of the drum 5. When the coiled tube 4 is in a non-central position, the...
