Abstract
The utility model relates to coal mine drilling exploration equipment, and particularly discloses a split slip for a chuck of drilling rig equipment. A body of the split slip consists of two parts, i.e. an upper body and a lower body which can be separated from each other, wherein the two parts are fixedly connected into a whole through a fastening piece; a guide bevel edge is arranged at the top of the upper body; a tooth part is arranged at the bottom of the lower body. The split slip is simple in structure and convenient to manufacture and mount; heat-treated high-hardness steel can be adopted for the lower body, so that the hardness of the tooth part is ensured; a high-toughness material can be adopted for the upper body, so that high overall impact resistance is ensured; in addition, due to the adoption of a split structure, the two parts can be conveniently machined respectively, the machining difficulty is low, and the cost is also lowered.
Description
Technical field
The utility model relates to a kind of colliery drilling equipment, specifically a kind of split type slips for drilling equipment chuck.
Background technology
Oild chuck clamps drilling rod, the important process parts that transmitting torque is realized bit cutting and crept into while being rig work.Can the slips in oild chuck clamp drilling rod is the key that can rig normally work, and common slips is all integral type at present.
When drill hole of drilling machine, be to throw successively drilling rod into same boring by root, rig punching is darker, and the resistance that drilling rod is subject to is just larger; The drilling rod radical of throwing into is more, and total length is longer, and drilling rod just can not be in a straight line, and beating of drilling rod also can be larger, just inhomogeneous to the wearing and tearing of slips tooth portion, the easier wear out failure of some part, and impact clamps effect.Present common way is to improve slips tooth portion hardness by heat treatment to solve this problem.After heat treatment, the tooth root portion hardness of slips bottom surface effectively improves, and abrasion resistance strengthens, but the both wings stress of slips upper inclined surface thinner thickness also increases simultaneously, and hardness also improves.Drilling in vibration processes, the both wings fragmentation of easily bursting apart produce vibration in the draw-in groove of slip sleeve time, damages whole slips, comes off from slip sleeve, loses clamping action, affects rig and drills.
The inclined-plane that existing common slips should be processed top in a block of material, processes bottom profile of tooth again, no matter processes which part processing error, and monoblock slips has just been scrapped, and waste of material is many, and difficulty of processing is large.
Summary of the invention
Technical problem to be solved in the utility model is, provides a kind of tooth portion to have higher hardness, overall strong shock resistance simultaneously, and long service life, is easy to processing, the split type slips that cost is low.
Split type slips of the present utility model, its body is made up of separable upper body and lower body two parts, between two parts, is connected and fixed and is integrated by firm, and the top of upper body is provided with guiding hypotenuse, and the bottom of lower body is provided with tooth portion.
The bonding surface of described upper body and lower body is provided with the boss and the groove that cooperatively interact.
The utility model is simple in structure, manufacture and easy for installation; Its lower body can adopt the high rigidity steel after heat treatment, has ensured the hardness of tooth portion; Its top can adopt the good material of toughness, has ensured overall good impact resistance; Simultaneously split type structure, is convenient to two parts and processes respectively, and difficulty of processing is low, has also reduced cost.
