Description
Technical Field
[0001] The utility model belongs to the technical field of petroleum drilling equipment, and in particular relates to a drilling wire rope vibration prevention device. Background Art
[0002] During the oil drilling process, the lifting system of the drilling rig drilling tools is mainly composed of a winch at a low position, a crown block at a high position, a traveling block drilling tools suspended above the wellhead, and a drilling wire rope. One end of the drilling wire rope is fixed and wound on the winch, and the other end goes up through the crown block pulley block, and then winds down on the traveling block pulley block. Through the forward and reverse rotation of the winch, the drilling wire rope is pulled to drive the traveling block to move up and down, thereby realizing the lifting or lowering of the drilling tools on the traveling block.
[0003] Since the winch is installed at the rear of the wellbore at the base of the drilling platform and the crane is installed at the center of the wellbore at the top of the derrick, the vertical drop between the two is generally about 50 meters, and the front-to-back distance is about 9 meters. The drilling wire rope from the crane to the winch is in a zero-constrained suspension state in the horizontal plane. When the winch rotates rapidly, this section of the drilling wire rope will produce forward and backward displacement under the combined action of its own weight and the lateral traction of the winch, that is, a slight vibration phenomenon, especially when the winch is quickly started and stopped, the vibration amplitude is the largest. In severe cases, it will cause the winch rope to be uneven, and the upper and lower layers of wire ropes will roll against each other, causing damage or destruction to the wire rope, which will significantly reduce the service life of the wire rope and affect the normal operation of the drilling rig.
[0004] The existing devices with similar wire rope anti-vibration functions in China generally have disadvantages such as high manufacturing cost, complex installation, and slow anti-vibration response speed.
[0005] Therefore, according to this situation, it is necessary to develop a drilling wire rope anti-vibration device, which is easy to use and can quickly reduce the vibration of the wire rope during work. Utility Model Content
[0006] The purpose of the utility model is to:
[0007] In order to solve the problems of high manufacturing cost, complex installation, slow response speed and high maintenance cost of existing wire rope anti-vibration devices, a drilling wire rope anti-vibration device is provided. The use of the device will not affect the normal operation of the wire rope, can quickly and effectively eliminate the vibration of the wire rope during operation, and reasonably protect the life of the drilling wire rope.
[0008] The technical solution adopted by the utility model is as follows:
[0009] A drilling wire rope anti-vibration device comprises a support column, a guide, a rope hanger, a guide rope and a tensioner, wherein the top end of the support column is fixedly connected to the guide, and the guide comprises a guide wheel, a rolling bearing, a fixed bracket and a rotating support device, the guide wheel is provided with an annular groove, the guide rope is installed in the annular groove, one end of the guide rope is fixedly connected to the rope hanger, and the other end of the guide rope is fixedly connected to the tensioner, the rope hanger comprises a shell, a wear-resistant block, a hinge and a locking mechanism, a drilling wire rope is inserted into the center of the rope hanger and installed, the lower end of the drilling wire rope is fixedly connected to a winch, and the upper end of the drilling wire rope is fixedly connected to a crown block.
[0010] Furthermore, two support columns are provided and are symmetrically arranged on both sides of the drilling wire rope, and a drilling platform working surface is provided below the support column, and the lower end of the support column is fixedly connected to the drilling platform working surface.
[0011] Furthermore, the guide is arranged in an axisymmetric manner and is installed on both sides of the rope hanger.
[0012] Furthermore, a guide wheel and a rotation support device are installed in the fixed bracket, a rolling bearing is installed at the center of the two end surfaces of the guide wheel, and the inner hole of the rolling bearing is fixedly connected to the rotation support device.
[0013] Furthermore, the guide rope is fixedly connected to the guide and the rope hanger to form a closed ring structure.
[0014] Furthermore, a wear-resistant block is fixedly installed in the shell, and both the shell and the wear-resistant block are cylindrical in shape consisting of two semi-cylindrical structures. A hinge and a locking mechanism are respectively connected to the outer wall of the shell, and the hinge and the locking mechanism cooperate to form a hinge-type structure that can be opened, closed and locked.
[0015] In summary, due to the adoption of the above technical solution, the beneficial effects of the utility model are:
[0016] The utility model adopts the design of inserting the drilling wire rope into the rope hanger to stop the vibration, which takes advantage of the consumption of the guide rope and reduces the adverse effects of the vibration of the drilling wire rope during operation. In addition, the shell and the wear-resistant block are both cylindrical in shape composed of two semi-cylindrical structures, and a hinge and a locking mechanism are respectively connected to the outer wall of the shell. The hinge and the locking mechanism cooperate to form a hinge-type structure that can be opened and closed and locked, and it is also more convenient and quick to replace the wear-resistant block, a consumable part. The production cost of the device is significantly reduced, and the use and maintenance cost is also correspondingly low, which greatly reduces the user's use cost.
[0017] In order to achieve the above purpose, the technical solution adopted by the utility model is as follows:

First, the drilling wire rope is passed through the rope hanger, and two guide ropes are reliably connected to the rope hanger on the left and right, and then the guide ropes are passed through the two guides respectively, and the guide ropes are tightened by the tensioner. In this way, the drilling wire rope and the device form a linkage body, which is equivalent to setting a hinge point for the drilling wire rope. When the drilling wire rope is working, it produces slight vibration, so that the drilling wire rope will contact the wear-resistant block, and the friction of the contact will drive the rope hanger to move back and forth between the two guides. Through the tightened guide rope, the drilling wire rope is artificially added with front and rear constraints, so that the vibration of the wire rope can be quickly eliminated.
[0019] The rope hanger consists of a shell, a wear-resistant block, a locking mechanism, and a hinge. The shell and the wear-resistant block are both cylindrical in shape, consisting of two semi-cylindrical structures. The drilling wire rope is inserted into the circular hole of the wear-resistant block through a hinge, and the two halves are closed into a fixed whole by the locking mechanism bolts.
[0020] A rolling bearing is installed between the guide wheel and the rotating support device, so that the friction of the guide wheel rotation is reduced, the guide rotates more flexibly, the response of the back and forth movement of the rope hanger is faster, and the influence of the excessive friction resistance of the guide itself on the operation of the drilling wire rope is reduced.
[0021] Compared with the prior art, the utility model has the following beneficial effects: simple structure, easy installation and fast anti-vibration response speed. BRIEF DESCRIPTION OF THE DRAWINGS

[0030] The guide 1 is axially symmetrically arranged and installed on both sides of the rope hanger 2. The rolling bearing 3 arranged at the guide wheel 4 of the guide 1 plays a role in reducing the friction resistance when the guide wheel 4 rotates, which can improve the sensitive speed of the rope hanger 2 moving back and forth and reduce the influence of excessive friction resistance of the guide wheel 4 on the operation of the drilling wire rope 14.
[0031] Preferably, the guide wheel 4 and the rotating support device 15 are installed in the fixed bracket 16, and a rolling bearing 3 is installed at the center of the two end surfaces of the guide wheel 4, and the inner hole of the rolling bearing 3 is fixedly connected to the rotating support device 15.

[0032] The guide rope 6 is fixedly connected to the guide 1 and the rope hanger 2 to form a closed ring structure. The rope hanger 2 is restrained by the guide rope 6 and moves back and forth only between the two guides 1.

A hinge 8 and a locking mechanism 10 are respectively connected to the outer wall of the housing, and the hinge 8 and the locking mechanism 10 cooperate to form a hinge-type structure that can be opened and closed and locked. When in use, the drilling wire rope 14 is inserted into the hole in the center of the wear block 9, and the two petals of the housing can be closed into a fixed whole by using the locking mechanism 10.
[0034] The present invention is further described below in conjunction with the accompanying drawings and embodiments. The present invention includes but is not limited to the following embodiments.
[0035] The above embodiment is only one of the preferred implementation modes of the present utility model and should not be used to limit the protection scope of the present utility model. Any changes or modifications that are made to the main design concept and spirit of the present utility model without any substantive significance, as long as the technical problems solved are still consistent with the present utility model, should be included in the protection scope of the present utility model.
[0036] The working principle of the utility model is as follows:
[0037] A vibration-proof device for drilling wire rope 14 is added to the drilling wire rope 14 between the overhead crane 13 and the winch 12 to perform human intervention on the drilling wire rope 14. The device does not affect the normal use of the wire rope, can reduce the vibration amplitude of the drilling wire rope 14 and even eliminate the vibration, and can maintain a reasonable service life of the drilling wire rope 14. The device includes a guide 1, a rope hanger 2, a support column 5, a guide rope 6, a tensioner 7, etc. A support column 5 is fixed on both sides of the drilling wire rope 14 on the working surface 18 of the drilling platform, and then two guides 1 are respectively installed and fixed to the top of the support column 5, and the two guides 1 are arranged symmetrically to each other. The drilling wire rope 14 is passed through the hole of the wear block 9 of the rope hanger 2, and then the upper end of the drilling wire rope 14 is connected to the crane 13, and the lower end of the drilling wire rope 14 is connected to the winch 12. One end of the two guide ropes 6 is reliably connected to the rope hanger 2 on the left and right, and then the other end of the guide rope 6 is respectively inserted into the annular groove 17 of the two guides 1, and then fixed on the tensioner 7. The guide rope 6 is tightened by adjusting the tensioner 7, so that the drilling wire rope 14 and the device form a linkage body, which is equivalent to setting a hinge point for the drilling wire rope 14. When the drilling wire rope 14 is working, it produces a slight vibration, so that the drilling wire rope 14 will contact the wear block 9, and the friction of the contact will drive the rope hanger 2 to move back and forth between the two guides 1. Through the tightened guide rope 6, the drilling wire rope 14 is artificially restrained in front and back, thereby reducing the amplitude of the vibration and eliminating the vibration.
[0038] The installation method of the utility model is as follows:
[0039] First, a support column 5 is fixed on the drilling platform working surface 18 on both sides of the drilling wire rope 14, and then two guides 1 are respectively installed and fixed on the top of the support column 5, and the two guides 1 are arranged symmetrically. First, the drilling wire rope 14 is inserted from the central hole of the wear-resistant block 9 of the rope hanger 2, and the two guide ropes 6 are reliably fixedly connected to the rope hanger 2 on the left and right, and then the guide ropes 6 are respectively inserted into the annular grooves 17 of the two guides 1 and fixed on the tensioner 7. The guide ropes 6 are tightened by adjusting the tensioner 7, so that the drilling wire rope 14 and the device form a linkage body, which is equivalent to setting a hinge point for the drilling wire rope 14. When the drilling wire rope 14 is working, it produces slight vibration, so that the drilling wire rope 14 will contact with the wear-resistant block 9. The friction of the contact will drive the rope hanger 2 to move back and forth between the two guides 1. Through the tightened guide rope 6, the front and rear constraints of the drilling wire rope 14 are artificially increased, thereby reducing the amplitude of the vibration until the vibration is eliminated. In summary, the installation and commissioning of the anti-vibration device of the drilling wire rope 14 is completed.
[0040] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
