Description

Technical Field

[0001] The invention relates to the technical field of drilling engineering, and in particular to a water lifting joint. Background Art

[0002] The wet drilling method is to use a core drilling machine to drill several holes along the inner edge of the pile diameter. The holes are connected and the core is taken after drilling. After all the holes drilled by the water drill are connected into a ring, the pile core and the pile wall are separated to form the free surface of the pile core. Then a hole is drilled in the pile core and a steel chisel is driven into the hole to crack the rock and break it into several small pieces. The stone is lifted out of the hole by a winch. During the operation of the core drilling machine, the drill bit must be kept in cooling water. At the same time, the cooling water flow maintains a certain pressure to directly flush the drill bit to prevent the drill from clogging or getting stuck. Therefore, this process is also called wet drilling or water drilling.

[0003] When the drilling rig in the coal mine is wet drilling, it is necessary to carry out long-term water lifting and diversion operations. Moreover, the water lifting and diversion process is not continuous, and water needs to be supplied intermittently according to the drilling progress. In addition, the water supply point is constantly changing, so the water lifting and diversion pipeline and pump need to be frequently disassembled and assembled, which puts high requirements on the performance of the water lifting and diversion joint. On the one hand, the joint is required to have a more reliable sealing under pressure conditions. On the other hand, the connection needs to be fast and convenient, and it should also be durable. At present, the water lifting and diversion joint has made great progress in the above two aspects. In addition, when the drilling rig is intermittently shut down, the water lifting and diversion joint also needs to ensure that it is available at any time. However, due to the lack of closures and authority management mechanisms in the water lifting and diversion joint itself, it is often temporarily occupied. Summary of the invention

[0004] The present invention aims to provide a water pumping joint to address the technical defects of the prior art, so as to solve the current technical problem that the water pumping joint is easily occupied during the shutdown stage due to the lack of a closure and an authority management mechanism.

[0005] In order to achieve the above technical objectives, the present invention adopts the following technical solutions:

[0006] The water-lifting joint comprises a water-lifting main pipe, an annular interface, a limiting groove, a discontinuity, a transmission ring, a buckle cover, a sealing plate, a driving motor, a short pipe, an eccentric column, a hole, a place-taking block, an inner ridge, and an annular protrusion; an annular interface is provided at the output end of the water-lifting main pipe, a limiting groove coincident with the axis thereof is provided on the annular interface, a slider is fixedly connected to the rear end of the transmission ring, the slider is limited in the limiting groove, a discontinuity is provided on the limiting groove, and the slider can be separated from the limiting groove when it moves to the discontinuity, the buckle cover is buckled outside the transmission ring, and a driving motor is installed on the buckle cover A sealing plate is fixed on the outside of the buckle cover, the driving motor is located between the sealing plate and the buckle cover, a short tube is fixed on the inside of the buckle cover, the short tube is maintained at the center position of the transmission ring, the eccentric column is maintained at the center position of the short tube and is connected to the driving motor, a hole is provided at the side end of the short tube, a placeholder block is reserved in the space between the eccentric column and the short tube, an inner ridge extending along the axial direction is provided on the inner edge of the transmission ring, an annular protrusion extending along the circumferential direction is provided on the inner edge of the transmission ring, a limiting groove extending along the circumferential direction is provided on the outer edge of the short tube, and the annular protrusion is confined in the limiting groove.

[0007] Preferably, a mechanical lock is provided between the sealing plate and the buckle cover, and a lock hole is provided on the outer side of the mechanical lock.

[0008] Preferably, a controller is installed between the sealing plate and the buckle cover, the controller is electrically connected to the driving motor, and a wireless module and a battery are provided on the controller.

[0009] Preferably, the water diversion main is arranged vertically, and a valve is provided in the water diversion main at a position upstream of the annular interface, and a control rod of the valve is located outside the water diversion main.

[0010] Preferably, the cross section of the limiting groove is in a broken line shape, and the cross section of the sliding block is in an L shape.

[0011] Preferably, the front and rear end surfaces of the transmission ring are both planes, and there are two inner ridges, which are arranged axially symmetrically.

[0012] Preferably, the radius of one side of the eccentric column is equal to the inner radius of the short tube, and the radius of the other side of the eccentric column does not exceed 1 / 2 of the inner radius of the short tube.

[0013] Preferably, the cross-section of the inner ridge is rectangular, trapezoidal or arched.

[0014] Preferably, the sealing plate and the buckle cover are integrally formed or fixedly connected by screws.

[0015] Preferably, an end of a bearing eccentric column is provided at the inner end of the transmission ring and is connected to the bearing.

[0016] In the structure of the present invention, since the short tube is fixed on the inner side of the buckle cover, the short tube can be rotated together with it when the buckle cover is manually rotated; when the placeholder is squeezed out of the hole by the eccentric column, the placeholder can rotate with the short tube and the buckle cover. At this time, the placeholder can push the inner ridge of the inner wall of the transmission ring, so that the transmission ring rotates, and then the slider at the rear end of the transmission ring rotates to the discontinuous position of the limiting groove, so that the slider, transmission ring, buckle cover, sealing plate, drive motor, short tube, eccentric column, etc. are separated from the annular interface as a whole, so that the annular interface can be used. On the contrary, when the eccentric column does not squeeze the placeholder, the placeholder remains between the eccentric column and the short tube. At this time, the buckle cover and the short tube are rotated. Since there is no placeholder to push the inner ridge, the transmission ring does not rotate, and the annular interface remains in a closed state. Therefore, by controlling the position of the eccentric column by the drive motor, it is possible to control whether the water pumping joint can be opened or not. In addition, the annular protrusion on the inner edge of the transmission ring fits into the limiting groove on the outer edge of the short tube, so that the short tube and the transmission ring can rotate relative to each other but will not separate.

[0017] The present invention discloses a water-lifting joint. This water-lifting joint is designed with an external locking component of a purely mechanical structure, and the feeding state of the placeholder block is controlled by the position of the eccentric column. Since the placeholder block is the only external force source that can act on the inner ridge on the transmission ring, it can determine whether the transmission ring can rotate with the buckle cover. Through the above principle, closed protection of the water-lifting joint is achieved. On this basis, combined with modules such as mechanical locks or electronic locks, the management of usage permissions can be achieved, thereby avoiding the problem of occupation of the water-lifting joint in the shutdown state.

[0028] The specific embodiments of the present invention will be described in detail below. In order to avoid too much unnecessary details, the well-known structures or functions will not be described in detail in the following examples. The approximate language used in the following examples can be used for quantitative expression, indicating that the quantity can be allowed to have a certain change without changing the basic function. Unless otherwise defined, the technical and scientific terms used in the following examples have the same meaning as those generally understood by those skilled in the art to which the present invention belongs.

[0029] Example 1

[0030] Water supply connection, see Figures 1 to 4 , including a water diversion main pipe 1, an annular interface 2, a limiting groove 3, a discontinuous portion 4, a transmission ring 5, a buckle cover 6, a sealing plate 7, a driving motor 8, a short pipe 9, an eccentric column 10, a hole 11, a placeholder 12, an inner ridge 13, and an annular protrusion 14; an annular interface 2 is provided at the output end of the water diversion main pipe 1, and a limiting groove 3 coinciding with the axis thereof is provided on the annular interface 2, a slider is fixedly connected to the rear end of the transmission ring 5, the slider is limited in the limiting groove 3, and a discontinuous portion 4 is provided on the limiting groove 3, and when the slider moves to the discontinuous portion 4, the limiting groove 3 can be separated from the slider, the buckle cover 6 is buckled outside the transmission ring 5, and a driving motor 8 is installed on the buckle cover 6, A sealing plate 7 is fixed on the outside of the buckle cover 6, and a driving motor 8 is located between the sealing plate 7 and the buckle cover 6. A short tube 9 is fixed on the inside of the buckle cover 6, and the short tube 9 is maintained at the center position of the transmission ring 5. The eccentric column 10 is maintained at the center position of the short tube 9 and is connected to the driving motor 8. A hole 11 is provided at the side end of the short tube 9, and a placeholder block 12 is reserved in the space between the eccentric column 10 and the short tube 9. An inner ridge 13 extending along the axial direction of the transmission ring 5 is provided on the inner edge of the transmission ring 5, and an annular protrusion 14 extending along the circumferential direction of the transmission ring 5 is provided on the inner edge of the transmission ring 5. A limiting groove extending along the circumferential direction of the short tube 9 is provided on the outer edge of the short tube 9, and the annular protrusion 14 is confined in the limiting groove.

[0031] Among them: since the short tube 9 is fixed on the inner side of the buckle cover 6, the short tube 9 can be rotated together when the buckle cover 6 is manually rotated; when the placeholder 12 is squeezed out of the hole 11 by the eccentric column 10, the placeholder 12 can rotate together with the short tube 9 and the buckle cover 6. At this time, the placeholder 12 can push the inner ridge 13 of the inner wall of the transmission ring 5, so that the transmission ring 5 rotates, and then the slider at the rear end of the transmission ring 5 rotates to the position of the discontinuous portion 4 of the limiting groove 3, so that the slider, the transmission ring 5, the buckle cover 6, the sealing plate 7, the drive motor 8, the short tube 9, the eccentric column 10, etc. are separated from the annular interface 2 as a whole, so that the annular interface 2 can be used. On the contrary, when the eccentric column 10 does not squeeze the placeholder 12, the placeholder 12 remains between the eccentric column 10 and the short tube 9. At this time, when the buckle cover 6 and the short tube 9 are rotated, since there is no placeholder 12 to push the inner ridge 13, the transmission ring 5 does not rotate, and the annular interface 2 remains in a closed state. Therefore, the position of the eccentric column 10 is controlled by the driving motor 8, so that the water lifting joint can be opened or not. In addition, the annular protrusion 14 on the inner edge of the transmission ring 5 fits with the limit groove on the outer edge of the short tube 9, so that the short tube 9 and the transmission ring 5 can rotate relative to each other but will not separate.
