Description

Technical Field

[0001] The utility model belongs to the technical field of drill rod fixing, in particular to a clamp for fixing a drill rod. Background Art

[0002] A drill pipe is a steel pipe with a threaded end. It is mainly used to connect the surface equipment of the drilling rig and the drilling and grinding equipment or bottom hole device at the bottom of the well. That is, it is used to transmit power to enable the drilling and grinding equipment to operate normally, transport drilling mud to the drill bit, help cool and lubricate the drill bit, and carry drill cuttings back to the surface. It raises, lowers or rotates the bottom hole device together with the drill bit to complete the drilling task. The drill pipe is usually fixed by threaded connection and limited by clamps to ensure the stability and safety of the drill pipe during the drilling process.

[0003] The utility model patent application, publication number 201821203792.2, discloses a drill pipe fixture comprising a drill pipe, a fixed fixture mounted on the drill pipe, and a rotating fixture. The fixed fixture and rotating fixture utilize two Ω-shaped half-tile structures that dock onto the drill pipe. The rotating fixture is tightly attached to and mounted behind the fixed fixture and can freely rotate around the drill pipe, resolving the problem of securing the drill pipe to a pipe-laying vessel. Furthermore, it addresses the technical challenge of allowing the drill pipe to rotate freely during drill bit removal.

[0004] According to the above patents, there are fixtures for fixing drill rods, but they still have shortcomings in actual use. The most obvious one is that the current fixtures usually fix the drill rods by clamping and limiting at both ends. The clamping and fixing on both sides can only limit the movement of the object in two directions, resulting in the drill rod still being likely to shake or displace, which may affect the accuracy and efficiency of the work. For this reason, we propose a fixture for fixing drill rods. Utility Model Content

[0016] 1. The rotating plate is driven to rotate by a driving member. Since an arc-shaped guide groove is provided on the rotating plate, and a connecting rod is slidably provided in the arc-shaped guide groove, the connecting rod slides on the slide rod through a moving block, so that when the rotating plate rotates, the connecting rod can be driven to move through the arc-shaped guide groove, and the clamping member is driven to move through the connecting rod, so that the four groups of connecting rods can move inward synchronously and clamp the rod body to a limit position, so that the rod body can be clamped and fixed in two directions, reducing the occurrence of drill rod shaking or displacement, and ensuring the accuracy and efficiency of the drill rod operation.

[0017] 2. By setting a fixing ring on the rod body, opening an anti-slip groove on the outside of the fixing ring, and opening a slot matching the anti-slip groove on the arc-shaped limit plate, the friction between the fixing ring and the arc-shaped limit plate is improved, ensuring the clamping stability of the drill rod.
