The purpose of this utility model is achieved in that
A kind of Coal quality sampler bit change-over removes specific purpose tool, comprise the fixed support 2 be arranged on support frame steel plate 4, the upper end of fixed support 2 is connected with screw type bit casing 1 by pulling claw steady pin 6, is provided with the screw type bit 8 adopting recessed bond ing with screw type bit casing 1 in screw type bit casing 1;
Described fixed support 2 adopts with pulling claw alignment pin 6 and is welded to connect;
Described support frame steel plate about 4 symmetry has screwed clamp nut 3, and the leading screw 5 and the fixed support 2 that match with clamp nut 3 are taked to be welded to connect;
Described fixed support 2 is two, and the support frame steel plate 4 in the middle of two fixed supports 2 is welded with hanger 7.
positive beneficial effect:the utility model structure is simple, designs ingenious.One is be the strong point according to Sampling Machine dowel hole, and " do force " as pulling claw, two is fix fastening bolt on plain plate, take nut " standby tight ", three is at plain plate center welding hanger, utilizes hand operated hoist " to catch on " hanger, the other end takes claim-reduction " rope " to live drill bit, chain block " catches on " claim-reduction, Constant load, and then drill bit reaches the object of dismounting smoothly.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
In figure be: screw type bit casing 1, fixed support 2, clamp nut 3, support frame steel plate 4, leading screw 5, grasp steady pin 6, hanger 7, screw type bit 8.
Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the utility model is described further:
As shown in Figure 1, a kind of Coal quality sampler bit change-over removes specific purpose tool, comprise the fixed support 2 be arranged on support frame steel plate 4, the upper end of fixed support 2 is connected with screw type bit casing 1 by pulling claw steady pin 6, the screw type bit 8 adopting recessed bond ing with screw type bit casing 1 is provided with in screw type bit casing 1, along with the continuous screw-in coal seam of screw type bit 8, the coal sample of coal seam different depth is continuously along with the impeller be connected with drill bit transports out;
Described fixed support 2 adopts with pulling claw alignment pin 6 and is welded to connect, and ensure firm welding, pulling claw is inserted in original Sampling Machine pinhole, and fixing reliable.；
Described support frame steel plate about 4 symmetry has screwed clamp nut 3, and the leading screw 5 and the fixed support 2 that match with clamp nut 3 are taked to be welded to connect.Requirement must be polished bevel for welding, and ensure through welding, surface weld and mother metal even transition, can not produce additional stress, is symmetrically welded layout with two supports.；
Described fixed support 2 is two, and the support frame steel plate 4 in the middle of two fixed supports 2 is welded with hanger 7; Described support frame steel plate 4 thickness 30 millimeters, in the perforate of fastening bolt place, ensure that fastening bolt can enter support frame steel plate 4 tapping smoothly, in the center of support frame steel plate 4, hanger is welded between two securing brackets, hanger takes low-carbon steel material, ensures with plain plate firm welding reliable.
Change sampler bit specific purpose tool, comprise screw type bit casing 1, on the original dowel hole of Sampling Machine casing, symmetrical insertion coordinates mild steel pole, diameter is slightly less than pinhole diameter, ensure that " turnover " is unobstructed, fixed support and mild steel pole take Welding Structure, ensure that firm welding is reliable.The other end of support welds mutually with the bolt of same diameter, must to polish during welding bevel for welding, ensure through welding, face of weld with support round steel rounding off, simultaneously in perforation place of fixed support and plain plate, " standby tight " clamp nut, in addition, at the center of plain plate welding dismounting hanger, as " suspension centre " of chain block, " drop " drill bit from Sampling Machine casing out, reach the object of dismounting.
Described support frame steel plate 4 thickness must reach bearing load requirement, through Mechanics Calculation, takes the steel plate of thickness 30 millimeters can reach bearing load requirement.
operation principle:
Change sampler bit specific purpose tool, adopt theory of mechanics, Sampling Machine casing pinhole is utilized to be locating hole, welding pulling claw, be " pulling claw fulcrum " with locating hole, pulling claw is welded in connection bracket, at the other end weld bolt of pulling claw, bolt penetrates on plain plate, after welding, pulling claw and support are symmetrically arranged along plain plate center, fastening bolt symmetry " standby tight " is in upper and lower two planes of plain plate, then at plain plate center weld hanger, the guarantee of hanger center and sampler bit are point-blank, when dismantling sampler bit, the chain block " catching on " hanger can uniform stressed, pull the claim-reduction be wrapped on sampler bit, chain block Constant load, drive drill bit to reach to dismantle with Sampling Machine cylindrical shell " stripping ".
