Description
Technical Field
The invention relates to the field of ship and ocean engineering construction, in particular to a durability torsion test tool for drilling equipment.
Background
A top drive, i.e. a top drive, is a common type of top drive drilling equipment. The rig must verify the integrity and reliability of the drilling system before delivery, i.e., the magnitude of the continuous torque produced by the test top drive at a constant rotational speed, is one of the key tests to test the performance of the top drive.
Top drives typically require endurance tests of 8 hours or even 48 hours duration, which require that a certain torque be applied to the top drive to simulate the drilling load. Therefore, in order to perform a test without actually drilling, a special tool is required to be designed so that a torque required for the test can be stably supplied for a long time in a top drive operation state.
Disclosure of Invention
In view of the above, the present invention provides a durability torsion test tool for drilling equipment, which can stably provide torsion required by a test for a long time in a top drive running state.
In order to solve the technical problems, the invention adopts the following technical scheme:
a drilling equipment durability torsion test tool comprises a water wheel shaft, wherein the water wheel shaft is a cylindrical pipe body, an internal thread sleeve is welded at the connecting end of the water wheel shaft, and the internal thread sleeve is matched with an external thread of a drill rod; the outer surface of the water wheel shaft is uniformly and vertically welded with four blades, so that the four blades are arranged at intervals of 90 degrees along the circumference of the water wheel shaft; in addition, the both sides welding of blade has the side shrouding, and the front end of side shrouding extends respectively to be connected with preceding blade side, and has the tip shrouding in the terminal welding of blade, and the tip shrouding both sides are connected with two side shroudings respectively for blade, two side shroudings, tip shrouding enclose into a semi-enclosed area jointly, increase the resistance in blade district.
Preferably, in order to ensure the structural strength of the water wheel shaft and bear the large resistance generated by the blade area during the test, reinforcing brackets are welded between the two side edges of each blade and the water wheel shaft respectively.
Preferably, the parts of the two adjacent reinforcing brackets, which are connected with the side sealing plates and the water wheel shaft, are provided with heavy plates, so that the integral reinforcing effect is achieved.
Compared with the prior art, the invention has the beneficial effects that:
the invention provides a simple tool for the durability torsion test of the drilling equipment, can carry out the durability test on the drilling system after installation and debugging are finished, can test the durability without actual drilling, saves time and greatly reduces the test cost; the tool can generate strong resistance due to the semi-closed area, and provides more accurate data for a torque test.
The reinforcing toggle plate has a certain area and is more in number, so that certain resistance can be generated in the rotation process of the test tool, and the torsion test of the test tool is facilitated. Under the operating condition, the test tool of the embodiment integrally comprises three resistance generation sites of a blade area, an upper reinforcing elbow plate area and a lower reinforcing elbow plate area.
