Abstract

The invention relates to a coal planer provided with a planer base which can run on a guide-chain rack of the coal planer. A supporting groove which can be used for installing an operating handle is arranged on the planer base; when the running direction in the coal planer is changed, the operating handle can enable a cutter frame to swing towards a working surface. The operating handle is supported in the supporting groove of the planer base through a spherical joint. The coal planer is connected with the traction section of one strip of planing chain only through the operating handle. Therefore, on the one hand, the operating handle can gain a support which cannot easily be worn; on the other hand, the coal planer can be independently driven by the operating handle.

Description

Coal planning apparatus

The present invention relates to the coal planning apparatus that a kind of raw material that extracts minerals is used, coal plough particularly, these facility have the planer body that can walk on the coal plough chain guides and one can be around the vertical rotating shaft line facing to the rotating knife rest of stope, wherein rotatably support a control stick in a supporting groove of coal plough matrix, and this control stick is connected with an one rod end on the traction section of a plane chain and with its another one rod end interlocking and in the recessed shelves of a dial of knife rest knife rest is swung when the traffic direction of coal plough changes.

This coal planning apparatus or coal plough once disclosed, and wherein control stick is frictional drive in the supporting groove of planer matrix or in the centre of matrix rather than is being supported with forcing transmission.This supporting is unsafty.Because the huge frictional force of meeting appearance causes wearing and tearing subsequently between control stick and planer matrix.In addition, the damage of the supporting groove of control stick and planer matrix must be considered, particularly when peak load occurring.The repairing of the planer matrix that causes the therefrom expense required with changing control stick is the same.Carry out the present invention for this reason.

Purpose of the present invention be exactly to develop a kind of resemble above-mentioned the coal planning apparatus of form of implementation, coal plough particularly, that the control stick of this machine is not only frictional drive but also be to force transmission, and can be bearing in the supporting groove of planer matrix agilely, wearing and tearing and damage are significantly reduced, and can change control stick easily fast.

The present invention finishes this purpose with this class coal planning apparatus, and that is exactly that control stick is supported in the supporting groove of planer matrix by a cup-and-ball joint.-this measure of the present invention at first can make control stick realize friction and be bearing in the planer matrix forcibly.Cup-and-ball joint resembles a properly universal joint supporting of constraint seemingly concerning control stick, it is agile, very not easy to wear again on the other hand on the one hand.Even when the infringement that is subjected to peak load, also need not worry supporting groove or planer matrix again so that the control stick infringement that is subjected to itself.On the basis of the infallible supporting of control stick, the present invention proposes another suggestion with original creation meaning again, that is exactly that coal plough only is connected with the traction section of plane chain by control stick, just coal plough is only spurred by plane chain by the binding of control stick and plane chain, therefore once to no longer having needed so as to the way that the increase plane chain is contained in the fastness on the coal plough with common chain hook insertion.The length of about 1/3rd planing tools makes the producing coal amount in this district reach the highest thereby coal plough can be advanced forward in the face end district again.

Other key characters of the present invention will be enumerated below.Another suggestion that has the original creation meaning equally that the present invention proposes be supporting groove is had become the sidewall of sliding wall and with cup-and-ball joint the condition that is slidingly matched, with the degree of depth and high movement clearance, the power of predetermined supporting groove being connected of transmitting that ground and structure coincide (Kraft-und formschluessig) be embedded between two sidewalls.So not only the supporting self of the universal joint formula used of control stick can realize, and whole cup-and-ball joint can obtain a supporting of floating seemingly.The activity space of Xing Chenging thus, cup-and-ball joint can be walked about within it like a cork, and when coal plough during by depression and pass, positive motion has just occurred.-the present invention also recommends such way, makes the bearing shell of the round cap shape of cup-and-ball joint have level and smooth outer wall so that cooperate with the level and smooth sliding wall or the sidewall of supporting groove, and makes control stick have an intercept sphere that is supported in two plate-likes between the bearing shell.The form of implementation of this cup-and-ball joint not only can obtain an agile control stick that is suspended on seemingly in the space, and also can guarantee to obtain a nonabradable supporting in addition, because the wearing and tearing that produce owing to the motion of control stick are shared by the circular arch face or the sphere of the even surface of cup-and-ball joint and control stick.Control stick and plate-like intercept sphere can constitute one at that time.Supporting groove preferably have the cross section of a box-shaped and gear to actual circumstances for cup-and-ball joint has guard ring, the most handy base plate of two other bearing shell or cover plate link together them.Cover plate can be with bolt and alignment pin and two bearing shells bindings, so that guarantee to change fast and easily control stick.

The present invention also has the another one suggestion to be, control stick is rabbeted in a vertical chain link that extends and thicken of plane chain with an one rod end of strengthening, and on this rod end, be provided for the horizontal chain link that is connected with vertical chain link or the interlocking ditch of its chain link arc side, so just can guarantee to make the chain link arc of horizontal chain link to have necessary movement clearance.
