Abstract
The invention relates to a coal mine drilling device, in particular to a split type slip used in a chuck of drilling machine equipment. A body of the split type slip is composed of an upper body part and a lower body part which are separable, the two parts are connected and fixed integrally through a fastener, a guiding inclined side is arranged at the top of the upper body, and a serrated part is arranged at the bottom of the lower body. The split type slip is simple in structure and convenient to manufacture and mount. The lower body can use a highly hard steel material after heat treatment, and hardness of the serrated part is guaranteed. The upper body part can use a material with fine tenacity, and fine overall shock resistance is guaranteed. Meanwhile, a split structure is convenient for the two parts to be processed respectively, and processing difficulty is lowered, and cost is also lowered.
Description
Technical field
The present invention 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 work, and common slips is all integral type at present.
During drill hole of drilling machine, be by root, to throw successively drilling rod into same boring, 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 by heat treatment, to improve slips tooth portion hardness 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.In the vibration processes of drilling, both wings produce the fragmentation of easily bursting apart of when vibration in the draw-in groove of slip sleeve, and whole slips is damaged, and from slip sleeve, come off, and lose clamping action, affect rig and drill.
Existing common slips should be processed the inclined-plane on top in a block of material, processes again bottom profile of tooth, which no matter is processed and partly process 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 by this invention is, provides a kind of tooth portion to have higher hardness, whole 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 invention, its body is comprised of separable upper body and lower body two parts, between two parts, by firm, is connected and fixed and is integrated, 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 boss and the groove cooperatively interacting.
The present invention is simple in structure, manufacture and easy for installation; Its lower body can adopt the high rigidity steel after heat treatment, has guaranteed the hardness of tooth portion; Its top can adopt the good material of toughness, has guaranteed whole 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.
Accompanying drawing explanation
Fig. 1 is the structural representation of the embodiment of the present invention;
Fig. 2 is the side structure schematic diagram of Fig. 1.
The specific embodiment
As shown in the figure, this split type slips, its body is comprised of separable upper body 1 and lower body 2 two parts, between two parts, by firm 3, is connected and fixed and is integrated, and the top of upper body is provided with guiding hypotenuse 4, and the bottom of lower body is provided with tooth portion 5.Upper body 1 is provided with the bonding surface of lower body 2 boss 6 and the groove 7 cooperatively interacting.
