Abstract
The plough of one coal mining etc. has one along the plough chain of adopting the extension of sky side, and is made up of two independent ploughs that have plough body.Plough body interconnects by the single-revolution joint, and each plough body extends below conveyer pan by means of the sword plate.Plough body is separately by being bearing on the front sidewall of related chain and flight conveyer trough at a horizontal supporting shaft that turns round on the central bearing.The vertical support axle of roller bearing constitutes the gyroaxis of plough body.The sword plate is installed on the plough chain independently, by deleting other knuckle joint commonly used, the sword plate is not connected mutually.Thus, obtain very strong cornering ability and the adaptive capacity by bend and swally and anticlinal strata the time.
Description
The present invention relates to a kind of mining plough apparatus, coal plough especially for underground job, it has along adopting the plough haulage chain that the sky side is extended, and form by at least two independent ploughs, plough has by the interconnective plough body of swivel coupling, and each plough body extends below conveyor pan by so-called sword plate.
In use, the sword plate of this plough apparatus interconnects by having along the joint pin of the horizontal expansion of ploughing lead usually.The necessary ability of adjusting to the ore bed bottom surface that like this, has just obtained when crossing swally and anticlinal strata, to be involved., because hinge joint, the sword plate of joint must be quite long, so the plough of lever arm and pick incision seam face is also long, sizable lever force that lever arm produces when being used for bearing plough apparatus work.Because the driving of plough will overcome the sliding friction of the front sidewall of related chain and flight conveyer, lateral force also will further increase.All these require to use bigger sword plate, and the ability of layer bottom surface-particularly adjusted to by bigger sword plate because swivel coupling-and usually be unsafty.Especially show the incompatibility bend.
Basic purpose of the present invention provides a kind of plough apparatus, the coal plough of the above-mentioned type particularly, independent plough and sword plate, they to bend to adapt to preferably and be adjustable on the performance of layer bottom surface through swally and anticlinal strata the time all be significant, have simple in structure and reliable effect simultaneously.
According to the present invention, provide a kind of mining plough apparatus, especially for the coal plough of underground job.
The effect that these characteristics of the present invention at first have is that the moment of flexure that acts on the hinge joint part between each plough can descend significantly.In addition, can realize control, because the synthetic quantity of power focuses on roller bearing to the satisfaction of lateral force.We can say by rolling movement and successfully slowed down lateral force that in addition, because the rolling friction between the front sidewall of the trough of each plough and their plough body and each transporter, lateral force has significantly reduced with respect to sliding friction.Plough apparatus when operation,, can be equipped with than the sword plate of much smaller particularly much shorter in the past for each plough because shearing causes the compensation on a large scale of lateral force.In addition, adopt on the sky side plough chain because these relatively shorter sword plates only are installed in, do not connect by joint or hinge, these sword plates are followed layer ability of bottom surface route and are better than the prior art structure greatly.Like this, just improved the ability of through swally and anticlinal strata the time, adjusting to the bottom surface.Suitable equally during through bend.Simultaneously, joint between two independent ploughs under any circumstance all have enough horizontal movement play with by the enough play that moves both vertically of bend-also have certainly with by swally and anticlinal strata-, make sword plate acquisition cornering ability by other knuckle joint commonly used of deletion.In addition, the present invention also makes one of independent plough have to can be used for the ore deposit (for example: the cutter pick of layer bottom coal), another independent plough has the cutter pick that can be used for ore bed top.By the structure of this pattern, each plough and their sword plate obtain moment of torsion about equally, and the moment of torsion between two blocks of sword plates is cancelled out each other.By this structure, strengthened above-mentioned effect.Can with respect to aspect around the cutter pick of vertical axis of rotation adjustment in a usual manner orientation be installed on the plough body.To this connection, each chuck of suggestion of the present invention possesses a recess, is used for part and holds its roller bearing, like this, guarantees shielded, the dustless assembling of roller bearing.
The advantage that the present invention obtained mainly is: the plough apparatus of having created the above-mentioned type, coal plough particularly, because shearing causes the remarkable compensation of moment of torsion and lateral force, the said equipment only need be used for the smaller of each plough and short especially sword plate, therefore, through swally and anticlinal strata the time, adjust to the ability of layer bottom surface, and cornering ability has strengthened significantly all.This is by fairly simple and operation device realization reliably, and in this device, each plough and each sword plate are spurred forward independently by the plough haulage chain.
Below by way of example,, the present invention is described in more detail with reference to accompanying drawing.
Fig. 1 is the floor map according to a plough apparatus of the present invention, does not wherein have related chain and flight conveyer trough.
Fig. 2 is the front elevation drawing of the plough apparatus of Fig. 1.
Fig. 3 is the partial cross-section of the plough of Fig. 1, comprises line pan.
Expressed the plough apparatus that is used to dig up mine among the figure, especially for the coal plough of underground job, a plough haulage chain 1 has been arranged among the figure, it promptly extends away from ore faces along adopting the sky side.The structure of this coal plough is made up of at least two independent plough 2a, 2b that have plough body 4a, 4b basically, and plough body 4a, 4b interconnect by swivel coupling 3, and each plough body 4a and 4b extend below conveyer pan 6 by sword panel assembly 5a, 5b.Plough body 4a, 4b are separately by being bearing on the groove sidewall 8 in coal front at the horizontal support roller assembly 7 that turns round on the central bearing.The vertical support axle 9 of roller bearing 7 is formed for the gyroaxis of plough body 4a, 4b.Sword plate 5a, 5b are installed on the plough chain 1 independently, and do not connect mutually, and in other words, the sword plate does not interconnect by hinge or other similar parts, so the sword plate can turn to vertical two planes in level.One of independent plough 2a has the cutter pick 10 that can be used for the ore bed bottom, and the plough 2b that another is independent has the cutter pick 10 that can be used for ore bed top.The chuck 12 that is used for additional pick can be adjusted around vertical axis of rotation 11 with respect to seam face, and orientation is installed on plough body 4a, the 4b in a usual manner.Each chuck 12 has one to be used for partly holding the recess 13 that supports roller bearing 7.Two swivel couplings 3 of ploughing between 2a, the 2b separately are made up of with the tongue 15 that is connected that is mounted in it jaw 14.One connecting pin 16 is housed, to adapt to motion, along the lateral rotation of plough lead on the tongue 15 at vertical plane.In addition, connect tongue 15 with plough lead and lead horizontal two aspect all have the predetermined horizontal play jaw 14 of packing into.Connecting tongue 15 has one in the hole that the plough moving direction prolongs, and holds connecting pin 16, connects tongue 15 laterally upwarping along the plough moving direction.The coal plough of finally making, each plough 2a, 2b and sword plate 5a, 5b not only have good especially turn performance by means of horizontal-shift, and by means of vertical shift, also possess the swally of strong especially adaptation ore bed bottom surface and the ability of anticlinal strata, in addition, because the compensation on a large scale of moment of torsion and lateral force can be installed relatively shorter sword plate.
