Description

Prevent that card pole area pole from rubbing to hinder drilling rod structure

Technical Field

The utility model relates to a friction resistance drill rod structure for preventing a rod from being clamped and carrying a rod.

Background

At present market conventional friction hinders drilling rod at work, because of intraductal card income foreign matter or when beating the clay layer, interior section pole frictional resistance increases passively, when host computer hoist wire rope promotes the drilling rod and withdraws interior section pole, interior section pole often takes place to take the pole phenomenon, leads to interior section pole to emerge, smashes bad anti-counterfeiting board and other parts of host computer, causes the unable work of host computer. For example, after a six-section friction resistance drill rod is punched after a fourth section of rod is stretched out, two sections of three sections of four sections of inner rods need to be withdrawn into one rod for soil throwing, the rod is withdrawn, foreign matters are clamped between the three four rods, or a large amount of clay exists in the gaps between the inner rods, so that the three sections of four sections of inner rods are not completely withdrawn, the third section of rod emits a distance from the top end of the second section, namely, the rod is taken, and the components at the top end of the drill rod and the related components of a host are damaged.

SUMMERY OF THE UTILITY MODEL

The utility model aims to solve the technical problems that an anti-counterfeiting plate is commonly used as a stop block function in the friction drill rod in the market, the problem of preventing rod clamping of each section of the drill rod is not refined, the heavy and heavy structure is complex and is not easy to maintain and replace, the maintenance cost is high, and once the rod clamping and rod carrying phenomenon occurs, secondary damage to a host machine is easily caused.

The technical scheme adopted by the utility model for solving the technical problems is as follows: the utility model provides a prevent that rubbing of kelly area pole from hindering drilling rod structure, establishes including drilling rod and cover last festival pole on the drilling rod, the periphery of last festival pole is provided with a plurality of interior festival pole, a plurality of interior festival pole overlaps the cover and establishes, and the top fixed mounting of the pole of the outer interior festival has anti-counterfeiting board, a plurality of the equal fixed mounting in inner wall top of interior festival pole has bellied ka tai, can support the ka tai bottom of holding in adjacent outside when the pole rebound of the interior festival of last festival pole or inboard.

Further: the clamping table comprises a plurality of stop blocks which are uniformly distributed along the circumferential direction, a U-shaped welding port is formed in each stop block, and an opening of the U-shaped welding port faces towards the anti-counterfeiting plate.

Further: the thickness dimension of the stop block is larger than the distance dimension between two adjacent inner-section rods, and the thickness dimension of the stop block is larger than the distance dimension between the last-section rod and the nearest inner-section rod.

Further: in the plurality of inner section rods, the length of the inner section rod is shorter than that of the adjacent outer inner section rod.

The friction resistance drill rod structure capable of preventing the clamping rod from being provided with the rod has the beneficial effects that through the clamping table structure provided with the plurality of stop blocks, when the clamping rod of the last rod or one section of inner rod is lifted up, the top end of the clamping rod can impact the clamping table arranged at the top of the outer inner rod adjacent to the clamping table, so that the problem that the inner rod breaks out and damages important parts is avoided, and meanwhile, the impact on the clamping table can remind a mechanical hand of the problem of the rod, and the drill rod is timely placed down for treatment. By parity of reasoning, the problem that the drill rod with the rod emerges can be solved in multiple prevention.

In the description of the present invention, it is to be noted that, unless otherwise explicitly specified or limited, the terms "connected" and "connected" are to be interpreted broadly, e.g., as being fixed or detachable or integrally connected; can be mechanically or electrically connected; may be directly connected or indirectly connected through an intermediate. The specific meanings of the above terms in the present invention can be understood in specific cases to those skilled in the art. In addition, in the description of the present invention, "a plurality" means two or more unless otherwise specified.

Any process or method descriptions in flow charts or otherwise described herein may be understood as representing modules, segments, or portions of code which include one or more executable instructions for implementing specific logical functions or steps of the process, and alternate implementations are included within the scope of the preferred embodiment of the present invention in which functions may be executed out of order from that shown or discussed, including substantially concurrently or in reverse order, depending on the functionality involved, as would be understood by those reasonably skilled in the art of the present invention.

As shown in fig. 1, the utility model provides a friction resistance drill pipe structure capable of preventing a clamping rod from being provided with a rod, which comprises a drill pipe 1 and a tail rod 2 sleeved on the drill pipe 1, wherein a plurality of inner rods 3 are arranged on the periphery of the tail rod 2, the inner rods 3 are overlapped and sleeved, an anti-counterfeiting plate 4 is fixedly installed at the top of the outermost inner rod 3, raised clamping platforms are fixedly installed at the tops of the inner walls of the inner rods 3, and the tail rod 2 or the inner rod 3 can be abutted against the bottom ends of the clamping platforms of the adjacent outer inner rods 3 when moving upwards.

This scheme during operation, when the 3 kelly belt rods of festival pole in end section pole 2 or a certain section lift, its top can strike in the 3 tops of festival pole in rather than the outside that closes on the ka tai that sets up, has avoided appearing in the festival pole 3 to emerge the problem of crashing bad important part, and striking ka tai can remind the aircraft hand to appear the belt rod problem simultaneously, in time transfers drilling rod 1 to handle. By parity of reasoning, the problem that the drill rod 1 protrudes out with the rod can be solved in multiple prevention modes.

Referring to fig. 2 and 3, the clamping table comprises a plurality of stop blocks 5, the stop blocks 5 are uniformly distributed along the circumferential direction, a U-shaped welding port 6 is arranged in each stop block 5, and an opening of each U-shaped welding port 6 faces the anti-counterfeiting plate 4.

When the pole problem drilling rod 1 is taken in the maintenance in building site, often need be changed because of preventing that the board 4 that emits is pounded, and it is big and the quality is heavy to prevent emitting 4 sizes, leads to the transportation inconvenience and cost of maintenance improvement. The stop block 5 can not only protect the anti-counterfeiting plate 4 from being broken by smashing, but also solve the transportation problem and reduce the maintenance cost due to the advantages of small shape, light weight and the like. The inner walls of the drill rod 1 and each section of the inner section rod 3 are circumferentially distributed at the upper end of the inner wall by a plurality of stop blocks 5, and the distance from the upper end surface is 50 mm. Welding wires are used for welding along the periphery of the U-shaped welding port 6, the design of the U-shaped welding port 6 effectively improves welding feasibility and welding strength, and the welding device can bear larger impact force.

The thickness dimension of the stop block 5 is larger than the distance dimension between two adjacent inner rods 3, and the thickness dimension of the stop block 5 is larger than the distance dimension between the last rod 2 and the closest inner rod 3. The thickness of the stop block 5 is designed according to the distance between the drill rods 1, so that the possibility that the stop block 5 falls down and is clamped into the drill rods 1 can be effectively avoided.

The length of the inner rod 3 of a plurality of inner rods 3 is shorter than that of the adjacent outer rod 3. This arrangement ensures that the bottom is at substantially the same height when the rod 3 is retracted, while the stop 5 is provided.
