Description

Conveyer

The present invention relates to a kind of scraping transporter that is used for mine operation, this transport plane has one along its transport plane of revolution for no reason chain belt that is vertically driven by middle actuating device, and this chain belt leads by conveyor frame, and conveyor frame then is made up of with the interconnective mosaic piece of multidirectional pivot line of centers longitudinally.This conveyor frame has the supporting member that can extend downwards, when supporting member stretches out, promptly wraparound is erected from ground to the conveyor chain of following cradle, and when supporting member was withdrawn, the carriage below then allowing is put on the ground.Between the mosaic piece of the framework of transport plane front portion, this conveyor frame also is equipped with the control oil cylinder that is used to adjust angle between the mosaic piece.

Open and described a kind of transport plane in British patent 1373170, it is by means of at its propulsive effort of transport plane actuating device longitudinally, conveyer belt is moved or advances, if desired even can pass through bend.This moment, supporting member promptly shrank, and the bottom bracket of transport plane chain belt is put on the ground, after moving forward, made the transport plane chain belt picking-up that forwards the bottom bracket place to transport plane enter feed status once more by means of stretching out of supporting member.

Say that in principle because these features have been arranged, this transport plane is applicable to underground mining.Because it can vertically move, coal and mineral can be discharged with keeping.Particularly on the scope of operation of so-called tunnel and ore pillar, these features have very big advantage.Yet the special transport plane described in the British patent still is not suitable for underground mining for some reason.First reason, the transport plane chain belt of this British patent is a slat conveyer, it is guided and is bearing on the roller by fixing guide pillar.Like this, the water of normal broken ore that occurs or infiltration will hinder the work of roller bearing and roller guiding in the underground mining operation, its as a result roller will soon stuckly not change.Thereby also just can not normally move.In addition, the component weight of this transport plane is big, so that when transport plane was worked, its a big chunk power all consumed in the motion of gyrating mass.The another one problem is, because the transport plane chain belt is to come transmission with chain drive-belt, therefore middle actuating device has bigger bottom-to-top-height and total length.Need cross may be the segment of curve of intensive or small curvature radius the time when middle actuating device, total length will certainly be crossed curve performance to conveyer belt greatly and bring adverse effect.At last, thisly itself can not set about or solve relevant transport plane chain belt according to the made transport plane of British patent and stretch and cross problem such as curve performance.When making application force pass on the transport plane chain belt by middle actuating device, will be stretched to a certain degree after chain belt and each the middle actuating device engagement.This stretching of chain belt must be revised so that it is the same with actuating device in the middle of the chain belt disengagement with proper method.Can not get revising if stretch and to leave in the middle of this actuating device at guiding transport plane chain belt and go to and encounter difficulties when actuating device gets in the middle of another.When the transport plane chain belt is gone on another middle actuating device, also same difficulty can appear in the corner.In the corner, because the swing of the mosaic piece of load-transfer device or rotation have just produced pitch error.This pitch error just make the middle actuating device that is adopted in this British patent chain drive-belt can not with transport plane chain belt correct engagement.

In this movably transport plane, because, displacement to be arranged or have the gap between the interconnective transporting chain plate of chain strips, so just can make Carrier chain link smoothly by segment of curve and be thus suitable for fitfull and transport occasion or mining operations line.For this transport plane that middle actuating device arranged and also for solve owing to the stretching of transport plane chain belt or elongation cause in the middle of actuating device draw off the problem that end occurs, its transporting chain plate must allow displacement each other.When the transporting chain plate that is provided was movable, the load-transfer device of actuating device was sagging shape in the middle of then leaving, thereby and this just can make coarctate carrier bar not push open to go wrong.Transporting chain plate can displacement be the US Patent NO.4 of bulletin on June 1 nineteen eighty-two each other, 332,317, and the theme described in the document of contriver Bahre etc.Yet the design of the transport plane of actuating device in the middle of this having is difficult to reasonably determine to constitute the displacement of chain type conveyer belt transporting chain plate or the degree or the size in gap.For fear of chain pushed away or part in compression becomes oversize owing to left middle actuating device when sagging when chain, the displacement between the continuous transporting chain plate should be big as far as possible.This also just helps the operation by the radius of curve smaller part, yet, if displacement is oversize, on the joggle piece that the joggle piece of actuating device drive wheel or sprocket wheel withstand on transporting chain plate in the middle of will causing and occur dangerous, for example, transporting chain plate is being pushed away or is going on the drive wheel and will be damaged during pressured state.Like this, for safely with drive wheel engagement, when transporting chain plate is pushed away and just needs as far as possible little displacement scale when being close to, but this has also just weakened the chain that forms with the transporting chain plate ability in the segment of curve operation.

Therefore, the object of the present invention is to provide a kind of scraping transporter that is used for mine operation, this transportation function moves voluntarily at its longitudinal direction, so that can cross segment of curve safely and guarantee the actuator energy normal occlusion or the engagement of actuator or the sprocket wheel and the transporting chain plate of middle actuating device at this.

According to self-propelled scraper plate chain conveyor provided by the present invention, above-mentioned purpose is achieved like this, and promptly it comprises: one by middle actuating device driving with by the band of rotary chain for no reason of the guide groove guiding of preparing along the conveyor frame center and the supporting member that can stretch out downwards from conveyor frame.When supporting member stretched out, it was promptly erected to the transporting chain plate of following cradle wraparound from ground, and when supporting member is withdrawn, then allows to be in following carriage and be put on the ground.This conveyor frame is made of mosaic piece, and mosaic piece is interconnective with multidirectional pivot along the transport plane longitudinal centerline, so that allow the conveyor frame not only can be on the horizontal surface but also can cross segment of curve on vertical surface.The control oil cylinder is housed, in order that adjust the angle between the mosaic piece between the mosaic piece of conveyor frame front portion.Conveyor frame constitutes a delivery chute, and chain has scrapes board member, scrapes board member and is moved in delivery chute by the chain drive.

Cross segment of curve in order to allow this transport plane, the transporting chain plate that connects together with the chain strips can displacement between mutually, and its displacement be in the middle of the function of pitch of teeth on the tooth of drive wheel and the drive wheel joggle piece on the actuating device, and when be in compress or during compressive state each transporting chain plate can abut against each other.The drive wheel of middle actuating device is made toothed gear wheel, and this just is similar to rack and pinion, and it not only directly meshed on top but also in the cradle of bottom chain.Maximum between transporting chain plate allows displacement to determine with following formula is approximate:

e＝ (0.3t)/(Z) （Z-9）

In the formula:

Permission displacement between the e=adjacent conveyor carrier bar:

The pitch of t=drive wheel, i.e. size between sprocket or the drive wheel teeth; With

The tooth number of the joggle piece of each drive wheel of z=or sprocket (denticle number is 10).

In addition, the running surface of the joggle piece of drive wheel and/or transporting chain plate is compared with the proper ingear profile of tooth of perseverance on certain point and is revised (permanent proper engagement is exactly to remain engagement with sprocket tooth top from the gear teeth in transmission to tooth root when carrier bar) a little, so just make the first half of running surface crooked backward towards symmetrical plane, promptly come to a point gradually, and the size that inclined to one side value is repaiied in the engagement of every pair of running surface should equal the permission displacement between the transporting chain plate.

According to above-described actuating device, the relation of these geometric conditions and size causes at first can realizing level and smooth contact between the recurvate first half of running surface of the joggle piece of setting any possible gap error, and along with the rotation forward of drive wheel, the contact point between the running surface is transferred to the lower part of running surface smoothly.The shape of the lower part of joggle piece should with for permanent proper engagement consistent with the given shape that certain standard clearance or pitch are arranged of geom.Have been found that and have only the constant or transmission stably that when at least one engagement contact between the lower part of a pair of running surface is given or has set up, could adopt the method realizable force of this correction running surface.In order to guarantee this contact, must limit each drive wheel joggle piece denticle number and limit the scope of the movable amount of transporting chain plate, the latter is then depended on the tooth number of drive wheel joggle piece.Stablize with level and smooth, shock-free transmission and can guarantee for one if the requirement on this size can be met.

Like this, the given diameter of drive wheel, the tooth number of joggle piece should be more the least possible if transporting chain plate needs big displacement.The good operation characteristic is arranged when impelling the joggle piece of forming with simple structure minimum tooth number allowable to be arranged and make chain run to segment of curve, preferably make each transporting chain plate have the hitching post that vertically extends out with the chain longitudinal direction, have in vertical both sides, the front and back of hitching post and make an attaching parts of shape ring as joggle piece.Launch by plane and the mutual vertical continuous of carrier bar that the connection eye thimble of each carrier bar is limited.Like this, because the attaching parts between the adjacent conveyor carrier bar only needs very little space, so the structure of this transporting chain plate allows the joggle piece of chain to arrange tight especially.Because this chain is made up of independent carrier bar.It manufactures advantageous particularly with regard to cost.And the type of attachment between this single transporting chain plate just makes chain as the chain of being made up of circular chain link usually sufficient flexibility be arranged.

Aforesaid scraper plate chain conveyor does not need the roller guiding and compares it with platform conveyer and have only a small amount of rotating mass to take exercises between delivery chute and chain.The middle actuating device that employing is vertically installed along transport plane is added flexible chain, and chain can be pushed under the state of elongation like this, thereby the flight chain about vertically just has only very little chain tension.Actuating device place in the middle of each, chain tension can be got rid of fully.According to the present invention, chain tension is the condition precedent of crossing curve performance for a short time, because be tending towards changing at the sense of motion of segment of curve chain, thereby has big chain tension.

Still all might adopt the middle actuating device that has the tooth-like drive wheel of direct engagement at bottom bracket because the size of middle actuating device is less in bracket.Such result is even that when crossing the segment of curve of minor radius, the curve motion track of load-transfer device can not be interfered yet.

Yet, adopt the middle actuating device that matches with retractable chain in its guide groove along the load-transfer device longitudinal direction, even this just need reasonably arrange chain that it also can be meshed with the drive wheel of middle actuating device well when the state of elongation.For example, the chain that moves on the drive wheel of actuating device in the middle of needing in dip plane or segment of curve will be in fully or the state of local elongation.When supporting member shrinks and transport plane same difficulty can occur during proal, the drive wheel of middle actuating device needs the mosaic piece of the chain of same pressurized to be meshed.Because it is flexible that this chain has, thereby formed pitch error can be very big.Yet, as already pointed out, according to the present invention, limit as tolerance between the carrier bar of the chain of the function of the pitch of drive wheel and the number of teeth and adopt the method for comparing with the profile of tooth of determining according to permanent proper engagement to revise that the ingear profile of tooth can make this pitch error value dwindle on drive wheel and/or the chain.

Generally speaking, result of the present invention has been to occur a kind of firm and the lotus that has good transcendental curve characteristic and be particularly suitable at underground mining that simply can move under itself propulsive effort effect is carved the scraper plate chain conveyor that uses under the service conditions.

Now then the narration accompanying drawing, particularly from Fig. 1 to Fig. 8, be installed in as can be seen transport plane longitudinally the mosaic piece of conveyor frame be to represent with corresponding numbering 1.Each mosaic piece 1 is made up of base plate 2 and cover plate 3, and they are linked to be a box component by vertical connecting panel 4 again.Central part in the bottom surface of the end face of cover plate 3 and base plate 2 all has a ditch shape guide groove 5, and it is the revolution that is used to guide conveyer chain at the longitudinal direction of transport plane, will describe in detail below the related content.

The pin 6 that each mosaic piece 1 usefulness of transport plane has the vertical direction hinge axis is connected with each other, and pin is arranged on along the longitudinal centerline of conveyor frame on the position of front and rear of each mosaic piece.Pin 6 allows adjacent mosaic piece 1 to have certain limit ground to rotate on horizontal surface, and so transport plane just can be by the segment of curve of about 4 meters arc radius.In addition, pin 6 also allows to have the rotation of certain limit in vertical surface, its result, and conveyer belt just also can be by the vertical loop line segment of 15 meters arc radius.Though conveyer belt vertically, pin 6 has the gap of moving about, however the lengths of frame of conveyer belt can not change.The setting that makes progress in the side of mosaic piece 1 is fixed with side plate 7.Side plate 7 and cover plate 3 be at the vertically mutually overlap joint of conveyer belt, like this, although each mosaic piece is still to form a delivery chute of tightening thus with what hinge linked to each other.

Every a mosaic piece 1 the hydraulically powered supporting member 8 that stretches out from vertical direction is housed in its both sides all.The adjustable height of supporting member 8 is such, and promptly when supporting member is withdrawn, the chain that is guided by the guide groove 5 of base plate 2 can be placed on the ground, and is that portability is carried whole transport plane (transportation ahead running) thus.When supporting member 8 stretched out, whole transportation frame rose, and can disengage (the hauling operation state of transport plane) like this with ground.

Along the longitudinal direction of conveyer belt, with actuating device 9 in the middle of 6～15 meters less like this spacing configurations.Middle actuating device is contained in the centre of the mosaic piece 10 of transportation frame, and the mosaic piece 1 with above-mentioned is the same to a great extent in its design.Mosaic piece 10 is just longer than mosaic piece 1 a little, but less than two times of latter's length.The gear type motor that drives a drive wheel 12 is housed in the mosaic piece 10 of actuating device 9 in the middle of having, and this drive wheel has the gear that is similar to the pin teeth, and related content will be described in detail below.The tooth of drive wheel 12 passes corresponding open slot on base plate 2 and the cover plate 3 and directly is meshed with the chain that is guided by guide groove 5, and these also will be described in detail below.Actuating device 9 also can have two drive wheels in the middle of each, and one is meshed with the following chain hook of chain, and another is meshed with last chain hook.

Be provided with tumbler 13 in the front portion of transport plane (seeing Fig. 7 and 8), the guide groove 5 that is used for chain is equipped with in its outside, is connected with each other by means of a suitable snyed plate 2 and cover plate 3 at this.At the back side of tumbler, tumbler 13 has one to connect pin 6 so that it is connected with the adjacent mosaic piece 1 of transportation frame.Between the tumbler 13 and first mosaic piece 1 and between mosaic piece 1 of mosaic piece 1 and back for the orientation of determining transport plane is equipped with can be at the control oil cylinder 15 of adjusting angle between the mosaic piece on the horizontal surface.

Chain (seeing Fig. 9 and 10) is made up of the horizontal feed carrier bar 17 of vertically arranged circular chain link 16 and special shape.Horizontal feed carrier bar 17 has the core 18 of a band open slot 19, and two vertical chain links 16 of adjacent transporting chain plate penetrate this open slot.All have a drive pin or a joggle piece 20(rounded substantially and that have a circular arc to see Figure 11 at each side of core 18), this part has the driving surface 20a and the 20b of symmetry.Free end at drive pin 20 has the guiding shoulder 22 that is meshed with the guide groove 5 that leads to chain.Guiding shoulder 22 is outwards give prominence to circular-arc, in order that horizontal feed plate 17 can also just can not produce locking phenomenon (of no force) around vertical axis swing thus when chain passes guide groove 5 in guide groove.Front side and rear side at guiding shoulder 22 all have stop surface 23; When the chain pressurized or be advanced into guide groove or during bend by certain circular arc, adjacent horizontal feed carrier bar 17 side by side headed on by this stop surface.

Stop surface 23 is on the one hand, and the circular chain link 16 that links to each other with transporting chain plate be for can limiting or determine the size of (e) value on the other hand, and owing to this (e) value is arranged, transporting chain plate 17 just can be in the mutual displacement of longitudinal direction of chain.(e) value should be than the flexible needed spacing of chain or amount of floating more greatly.Along with the stretching of chain, the spacing value (t) that just can reach benchmark in the driving surface 20a or the distance between the 20b of adjacent transporting chain plate 17 or meet pitch on the joggle piece that forms by transporting chain plate.

Shown in Figure 11 is the local figure of a drive wheel 12 that is meshed with the joggle piece of transporting chain plate 17.Drive wheel links to each other with an actuating device, not expression among the figure.Drive wheel 12 has joggle piece or sprocket 24, and each tooth all has two symmetrical driving surface 24a and 24b relative or that become mirror image to be inverted.

For joggle piece being pushed away under (e) value condition or normal engagement all being arranged during pressurized, according to the present invention, (e) the value numerical value that should be determined and setting by the number of teeth (Z) of the joggle piece of pitch (t) and drive wheel 12.In order to make joggle piece 20 and drive wheel 12 be pushed away or all can mesh smoothly during pressurized at transporting chain plate 17, and make itself and joggle piece 24 no slippages, then on the one hand, spacing (e) value must be set with definite method, on the other hand, the shape of joggle piece 20 and/or 24 driving surface must be revised with an accurate method.The approximate value of the maximum permissible value of the displacement between delivery board can be determined by following formula:

e＝ (0.3t)/(Z) （Z-9）

In the formula:

The displacement that allows between the e=transporting chain plate;

The pitch of t=drive wheel 12, i.e. distance between joggle piece 24 line of centerss; With

The number of teeth on the joggle piece 24 of Z=drive wheel 12, this value must not be less than 10.

Such as, when tooth number Z=13 and pitch t=100mm, according to above-mentioned formula, movable value (e) is 9.32mm.

In addition, according to the present invention, the driving surface 24a of the joggle piece 24 of drive wheel and the profile of tooth of 24b are compared with a permanent appropriateness or ingear shape and are revised, the first half that makes driving surface 24a and 24b is crooked backward or be the shape that comes to a point gradually towards symmetrical plane 24c, equals the movable amount (e) of transporting chain plate in the top end of driving surface 24a and 24b and the difference of the profile of tooth of a permanent appropriateness until it.In the analysing and observe of Figure 11, dot out the profile of tooth of permanent appropriateness or ingear driving surface 24a and 24b.Though the available profile of tooth that other generally adopts, the profile of tooth before revising in the present invention is to belong to involute gear profile series.The revised profile of tooth of driving surface 24a and 24b is shown in solid line.

As the another one method, can certainly adopt the method for comparing and revising on a small quantity to the driving surface 20a of the joggle piece on the transporting chain plate 17 20 and the first half of 20b with permanent appropriateness or ingear profile of tooth.So, the first half of plane of action is crooked backward or be the shape that comes to a point gradually towards the plane of symmetry, equals the movable amount (e) of transporting chain plate 17 in the difference of the top end of driving surface 20a and 20b and permanent proper profile of tooth until it.This part content will give to describe in conjunction with Figure 16 again.

At last, the method that the driving surface 20a of the joggle piece 20 of the driving surface 24a of the joggle piece 24 of drive wheel 12 and the profile of tooth of 24b and transporting chain plate 17 and the profile of tooth of 20b can be simultaneously compared and revised on a small quantity with permanent appropriateness or ingear profile of tooth, the first half that makes driving surface 24a and 24b and driving surface 20a and the 20b all symmetrical plane towards each joggle piece is crooked backward, until its a pair of driving surface 24a of top end at driving surface 24a and 24b or driving surface 20a and 20b, 20b or 24b, the difference of the profile of tooth of 20a and permanent appropriateness also equals the movable amount (e) of transporting chain plate 17, this difference table is shown the combination of two embodiment recited above, is not shown specifically in this figure.

The operating principle of conveying arrangement of the present invention will be given below to describe in detail by Fig. 9 and Figure 11.Suppose that in the drawings drive wheel 12 is that gap between the joggle piece 20 of joggle piece 24 and transporting chain plate 17 of right-hand revolution and this drive wheel contacts continuously, like this, 17 of the transporting chain plates shown in Figure 11 move from left to right.If joggle piece 20 has normal pitch value (t), and have can permanent appropriateness or the normal profile of tooth of ingear, and then driving surface 20a and 20b only contact with the driving surface 24a of the joggle piece of drive wheel 12 and the lower part of 24b.

Yet, if joggle piece 20 moves mutually and is close together or at the longitudinal direction force together of chain, the joggle piece 20 on the left side as shown in phantom in FIG..When at first being in contact with one another with the top through revising of the driving surface 24a of left side joggle piece 24, its driving surface 20b also just can not produce fierce impact to this one.Then insert joggle piece 20 in the neutral between joggle piece 24, driving surface 20b along the downward slippage of driving surface 24a till the part with driving surface 24a unmodified contacts.Arrive this, be restored keeping permanent appropriateness or nibbling with required condition.Two joggle pieces 20 in the right among the visible Figure 11 of wherein said meshing condition.

As can be seen from Figure 11, only between being no more than the joggle piece 24 of the joggle piece 20 that moves under the condition of (e) value and drive wheel 12, amount that can displacement can smoothly mesh.Should (e) value itself can determine by formula recited above again.High-precision engagement is measured and is correspondingly revised active flank, just can make it be adapted to higher level, and its result also no longer only is limited to the constant force transmission can occur in the non-modification region in the bottom of active flank 24.

According to Figure 12 and embodiment shown in Figure 13, each forms the transporting chain plate of chain to number 26 expressions.Each transporting chain plate 26 is all formed by the hitching post 28 that stretches out with the perpendicular direction of load-transfer device longitudinal direction with by the attaching parts of being made by eye shape ring 30 and 32 of the vertical relative both sides that are contained in hitching post.The extended surface of eye thimble vertically and wherein has an extended surface to be in the horizontal surface of conveyor chain mutually.Like this, the eye thimble 30 and 32 of adjacent transporting chain plate 26 is just as chain is formed the mutual interlock of chain link.Eye thimble 30 and 32 allows that certain amount of floating is arranged between transporting chain plate, and described amount of floating than the flexible needed amount of chain more greatly.Because amount of floating has been arranged, transporting chain plate 26 is the distance of (e) value of the mutual displacement of energy just.

Two side ends section at hitching post 28 is provided with the joggle piece 34 that is meshed with drive wheel shown in Figure 13 36.Driving surface 34a and 34b(that joggle piece 34 has symmetry see Figure 13).

In addition, as shown in figure 12, with regard to some transporting chain plate 26, also have scraper plate iron core 38 or other conveying member on the hitching post 28.

Figure 13 represents to have joggle piece 34 intermeshing situations on the chain of the local teeth of drive wheel 36 of joggle piece 40 and transporting chain plate shown in Figure 12 26.Under the given condition of this kind, the joggle piece 40 of drive wheel 36, has in an identical manner gradually to the place, plane of the plane of symmetry 40C of joggle piece 40 to come to a point and the top half of forniciform backward driving surface 40a and 40b illustrated in fig. 11 similar to previously.

Transporting chain plate pitch (t) in Figure 12 and 13 is especially little, and this number of teeth (Z) that just means the joggle piece 40 on drive wheel 36 can be many.

Represented the embodiment of four kinds of different chains in Figure 14 d at Figure 14 a.Actuating device of the present invention is guided and be specially adapted for to these chains.Described Figure 14 a is made up of identical in each case part to the chain of 14d.
