Description
Technical field
The present invention relates to a kind of flitting arc coal board, particularly relate to a kind of pin tooth transmission arc coal board mechanism with self-locking device, belong to coal excavation apparatus technical field.
Background technology
Coal-winning machine is the capital equipment of mechanical coal mining, and its function is coal breakage and coalings.At present, most widely used coal-winning machine is flitting.In the course of the work, the coal that pick cutting is got off by the helical blade by cylinder installs in drag conveyor flitting, but adopts for bowing greatly and particular job face such as girdle, only very undesirable by its effect of loading.
For improving the effect of loading coal of flitting, increasing spillplate device is the current a kind of mode generally adopted.Spillplate device is positioned at after cylinder, in order to improve the effect of loading coal of cylinder, and can prevent cylinder from outwards throwing coal and suppress coal ash to fly upward.Spillplate device generally has arc coal board and gate-type spillplate two kinds of forms, and the effect of loading coal of arc coal board is better than gate-type spillplate, thus applies more general.
Arc coal board is generally divided into freely convertible and convertible two kinds of automatic control according to upset mode.Freely convertible arc coal board is enclosed within rocking arm planetary mechanism, freely can overturn, in the course of the work, make it be in suitable operating position by measures such as self gravitations; The convertible arc coal board of automatic control drives arc coal board to overturn by motor by gear drive.
Freely the advantage of convertible arc coal board is that structure is simple, but shortcoming is it often can not be in desirable operating position, needs a large amount of manpower of cost to adjust it.The convertible arc coal board of automatic control solves the shortcoming of freely convertible arc coal board, automatically the position of spillplate can be adjusted according to actual needs, but it still has two large deficiencies urgently to be resolved hurrily at present: (1) automatic control type arc coal board often adopts gear-ring gear transmission, but conditions down-hole is severe, sealing effectiveness is difficult to ensure, coal ash is easy to get into travelling gear inside, and the time is not grown and just filled up by ring gear, and then causing transmission stuck, arc coal board cannot overturn; (2) automatic control type arc coal board generally adopts hydraulic motor as power source, but hydraulic motor exists internal leakage, and arc coal board cannot be locked in fixing position by it.
In view of this, nowadays in the urgent need to designing a kind of new flitting arc coal board, large not enough with solve current automatic control type arc coal board two.
Summary of the invention
The technical issues that need to address of the present invention are, the convertible arc coal board of existing automatic control often adopts gear-ring gear transmission, but conditions down-hole is severe, sealing effectiveness is difficult to ensure, coal ash is easy to get into travelling gear inside, time is not grown and is just filled up by ring gear, and then causes transmission stuck, and arc coal board cannot overturn; Automatic control type arc coal board generally adopts hydraulic motor as power source, but hydraulic motor exists internal leakage, and arc coal board cannot be locked in fixing position by it.
The present invention takes following technical scheme: a kind of pin tooth transmission arc coal board mechanism with self-locking device, comprises arc coal board assembly 1, round pin tooth 2, hydraulic motor 3, driving wheel 5, brake assembly 4, braked wheel 6; Described arc coal board assembly 1 comprises revolving sleeve, the circumference of described revolving sleeve is fixed with round pin tooth 2, form pin wheel 1a, revolving sleeve is connected with arc coal board 1c by jib, the described arc coal board assembly 1 star institution freedom that can detour rotates, and axial restraint; Described hydraulic motor 3 is fixed in shearer ranging arm guard shield by set screws III; Described brake assembly 4 is fixed in shearer ranging arm guard shield by set screws IV; Described driving wheel 5 is arranged on hydraulic motor, engages with pin wheel; Described braked wheel 6 is arranged on the axle of brake assembly, engages with pin wheel; Hydraulic motor 3 drives driving wheel 5 to rotate, and driving wheel 5 drives pin wheel 1a to rotate, and drives arc coal board assembly 1 to adjust position; Brake now in brake assembly 4 is in the state of declutching, and braked wheel 6 rotates with pin wheel 1a; Once arc coal board stops upset, the brake in brake assembly 4 and band-type brake, arc coal board pins by braked wheel 6; Pin tooth exposed drive, coal ash cannot be piled up on round pin tooth.
The feature of the technical program is: drive driving wheel to rotate by hydraulic motor, driving wheel engages with pin wheel and drives arc coal board to overturn, and the brake now in brake assembly is in the state of declutching, and braked wheel rotates with pin wheel; Once arc coal board stops upset, the brake in brake assembly and band-type brake, braked wheel cannot rotate, thus be pinned by arc coal board; Special design pin tooth exposed drive targetedly, coal ash cannot be piled up on round pin tooth, can avoid conventional gears-ring gear transmission due to ring gear inner product coal causes that arc coal board is stuck cannot the generation of flop phenomenon.
Further, described brake assembly 4 comprises brake 4d, holder 4c, bearing 4b, axle 4a, and described axle is by bearings on holder, and its one end is connected with brake, and the other end is for connecting braked wheel.
Further, described jib comprises jib 1b1, lower jib 1b2, and revolving sleeve comprises pivoted housing 1a1 and lower revolving sleeve 1a2 last time; Upper jib 1b1 and last time pivoted housing 1a1 weld together composition upper rotary grip assembly, lower jib 1b2 and lower revolving sleeve 1a2 welds together the lower revolving sleeve assembly of composition; Upper rotary grip assembly and lower revolving sleeve assembly are enclosed within rocking arm planetary mechanism, and put together on together by set screws I; Curved baffle 1c is put together on upper jib and lower jib by set screws II.
Further, described brake assembly (4) is controlled by special hydraulic circuit, according to the band-type brake of the stopping of arc coal board assembly (1), dynamic control brake assembly (4), declutches.
Beneficial effect of the present invention is:
(1) adopt pin tooth exposed drive, coal ash cannot be piled up on round pin tooth, can avoid conventional gears-ring gear transmission due to ring gear inner product coal causes that arc coal board is stuck cannot the generation of flop phenomenon;
(2) be provided with brake assembly, do not need to be pinned immediately when rotating at arc coal board, due to coal-winning machine work time, arc coal board is stressed, and the arc coal board that the present invention can avoid the interior leakage of hydraulic motor to cause can't lock the generation of phenomenon.
(3) safe and reliable, there is the application prospect extensively promoted.
