Abstract
The utility model relates to a cutting pick remover, which comprises a wedge spade type removing head, and a handle connected with the removing head. The removing head is provided with a fork opening; the inner diameter of the fork opening is larger than the outer diameter of the handle part of the cutting pick. As for the cutting pick remover, recycled wastes and old cutting pick heads can be adopted as basic materials to be forged into the wedge spade type removing head which is provided with the fork opening with the inner diameter larger than the outer diameter of the handle part of the cutting pick; moreover, the structure and dimension of the handle part of the original cutting pick are not changed at all, and the handle still serves as the handle of a new tool; therefore, the cutting pick remover has the advantages of simple manufacturing technique, durability in use, saving cost for cone alternation, greatly reducing the labor intensity, reducing the consumption of tools and materials, being capable of being recycled, saving energy and improving efficiency simultaneously.
Description
Technical field
The utility model relates to a kind of taking-up tool device, particularly relates to a kind of pick withdrawing device.
Background technology
The work of coal-winning machine mainly is to rotate by cylinder, and the pick on the cylinder cuts down coal again.Pick inserts in the pick cover on the machine, and then fixes with jump ring.When pick may wear to a certain degree, just need to take off the pick that more renews.But in the operating mode of reality,, cause old pick often to be difficult to take out owing to reasons such as the bonding of coal slime, local impaired and distortion.Conventional way of the prior art is to prize (the position A that prizes has been shown among Fig. 1) with screwdriver, the efficient of this kind operation is very low, and because the elongate rod body characteristics of screwdriver, and the single-point in the operation is stressed also unreasonable, so, be difficult to adapt to the need of work of frequent replacing pick, screwdriver bending, distortion, phenomenon such as turned are got off often just to cause by class.
The utility model content
The purpose of this utility model is, overcomes the defective of above-mentioned prior art and a kind of simple in structure, pick withdrawing device that can improve the instrument stressing conditions is provided.
For achieving the above object, the utility model is taked following design scheme:
A kind of pick withdrawing device comprises that wedge shovel type takes out head and the handle that links to each other with described taking-up head, has prong on the described taking-up head, and the internal diameter of described prong is greater than the shank external diameter of pick.
Preferably, described taking-up head is made by waste and old pick head.
Preferably, the bottom of described prong is semi-circular.The internal diameter of described prong is than the big 1～3mm of shank external diameter of described pick.
Preferably, the interior port radius of described prong is R25mm, R20mm or R15mm.
Preferably, the prong axial depth from the spear of described taking-up head to described semi-circular bottom is 2.5R.
The utility model the utility model has the advantages that: owing to can adopt the waste and old pick head of retrieving as stock, be forged into the taking-up head of wedge shovel type, and have the prong of internal diameter greater than pick shank external diameter, the shank structure and the size of former pick are motionless fully, and still the handle as new tool uses.So it is simple, durable in use to the utlity model has manufacturing process, save the screwdriver expense, and alleviated labour intensity widely, reduced the consumption of Work tool and material; Also have simultaneously recycling, the advantage that energy-conservation wound is imitated.
Description of drawings
Fig. 1 is the structural representation of pick in the prior art;
Fig. 2 is a structural representation of the present utility model.
The specific embodiment
Referring to Fig. 2, the preferred embodiment of a kind of pick withdrawing device of the utility model shown in it, comprise that wedge shovel type takes out head 1 and the handle 2 that links to each other with described taking-up head 1, preferably, described wedge shovel type takes out head 1 and is made by the waste and old pick head of retrieving, and so both is convenient to draw materials, can reuse waste product more, save the energy, have prong 3 on the described taking-up head 1, the internal diameter of described prong 3 is greater than the shank external diameter of pick.Described prong 3 can adopt earnestly or existing technology such as cold working, makes a semi-circular prong, then through Quenching Treatment, and reconditioning internal orifice cutting edge again.Preferably, the bottom of described prong 3 is semi-circular.So can match with the column type shank of pick to be removed bottom.
Preferably, the internal diameter of described prong 3 is than the big 1～3mm of shank external diameter of described pick.And referring to Fig. 2, the preferred radius of described prong 3 internal orifices is R25mm, R20mm or R15mm.So, can satisfy the taking-up work of different model pick.
In addition, for convenient operation, the prong axial depth from the spear of described taking-up head 1 to described semi-circular bottom is 2.5R.
The utility model can be motionless fully with former pick shank physical dimension, still as new tool---and the handle of pick withdrawing device uses.In addition, manufacturing process is simple again for it, and is durable in use, can save the screwdriver expense, and alleviated labour intensity greatly, reduced instrument and material consumption, and have recycling, the advantage that energy-conservation wound is imitated.
Obviously, those of ordinary skill in the art can constitute various types of withdrawing devices with a kind of pick withdrawing device of the present utility model.
The foregoing description is only for the usefulness that the utility model is described; and be not to be to restriction of the present utility model; the those of ordinary skill in relevant technologies field; under the situation that does not break away from the utility model scope; can also make various variations and modification; therefore all technical schemes that are equal to also should belong to category of the present utility model, and scope of patent protection of the present utility model should be limited by each claim.
