Description
Technical field
The present invention relates to a kind of low seam mining machinery running gear, particularly relate to a kind of low seam mining machinery back-buckling type running gear, belong to coal-winning machine running gear technical field.
Background technology
Low seam mining machinery running gear is made up of road wheel, long splined shaft, bearing, bearing support and guide slip shoe etc.Long splined shaft utilizes the external splines at two ends to engage with the internal spline of planet carrier and road wheel respectively, by power transmission to road wheel.
After road wheel obtains the power passed over from traction electric machine, engage with the rack rails in drag conveyor pin row, realize the walking on drag conveyor.Meanwhile, on road wheel assembly, two guide slip shoes in left and right and two of rib side support the weight that piston shoes support coal-winning machine, also by the guide effect of four spigot surfaces of guide slip shoe, ensure road wheel and normal engagement of rack rails and are unlikely coal-winning machine and slide down.
According to the difference (right-hand thread, left-hand thread) of supporting scrapper conveyor pin row mounting means, guide slip shoe also has right-hand thread and left-hand thread two kinds of forms, guide slip shoe hook is pin row back-buckling type towards rib side, guide slip shoe hook reverse rib side is the positive button of pin row, guide slip shoe right-hand thread can utilize bearing support as axis of rotation due to it, therefore, it is possible to around road wheel central axis (± 5 °), as Figure 1-Figure 2.
In prior art, for " left-hand thread " formula walking mechanism, owing to being subject to the restriction in space and structure, all left-hand thread guide slip shoes are all fixed, and guide slip shoe (main body is made up of guide holder and wear-resistant block two parts) bolton is being drawn on housing, mainly there is the deficiency of three aspects in this form of structure: 1. guide slip shoe can not rotate vertically.Due to low seam mining machinery space constraint, in addition the form of structure of " left-hand thread ", does not have suitable position to install guide slip shoe, can only be fixed in towing tank, when this just makes work plane have a fluctuating, traction is easily transshipped, even occur that holding impact is normal produces; 2. guide slip shoe is axially fixed, cannot horizontal play, and this just proposes very high requirement to the glacing flatness of drag conveyor passing, adds the labour intensity of workman; 3. structure and space limit, and guide slip shoe can not make monoblock cast structure, and be made up of guide holder and wear-resistant block, intensity is poor, and not easily change after damaging, and maintainability is poor, and its structure as Figure 3-Figure 4.
Summary of the invention
The technical issues that need to address of the present invention are: " left-hand thread " of the prior art formula walking mechanism, 1. guide slip shoe can not rotate vertically.Guide slip shoe is fixed in towing tank, and when work plane has fluctuating, traction is easily transshipped, even occur that holding impact is normal produces; 2. guide slip shoe is axially fixed, cannot horizontal play, and this just proposes very high requirement to the glacing flatness of drag conveyor passing, adds the labour intensity of workman; 3. be made up of guide holder and wear-resistant block, intensity is poor, and not easily changes after damaging, and maintainability is poor.
The present invention takes following technical scheme:
A kind of low seam mining machinery back-buckling type running gear, comprises guard shield 1, guide slip shoe 2, bearing support 8, major axis 7; Described guard shield 1 is provided with the boss 1a for support guide piston shoes 2, and described boss 1a is circular arc, and arc gap is downward; Described guide slip shoe 2 has annular brace circle 2a, described annular brace circle 2a hanging sleeve is on described boss 1; Described boss 1a, as the axis of rotation of guide slip shoe, enables guide slip shoe along its circumferential flexible rotating ± 5 ~ 10 °; The gap for guide slip shoe 2 axial float is left between guard shield 1 and bearing support 8.
The feature of the technical program is: the guard shield being provided with a kind of coal-winning machine back-buckling type running gear of special construction, guard shield arranges the boss of circular arc, the bracing ring of annular is set on guide slip shoe again, by both sockets, make guide slip shoe obtain can also carrying out slightly rotating and axial slightly play by boss arcuately while guard shield supports, improve the compliance of coal-winning machine in face with complex.
Further, also comprise road wheel 9, long splined shaft 7, road wheel 9 is directly connected in long splined shaft 7 end, engages with pin rail 6, reduces machine height, and increases coal space.
Further, guard shield 1 is arranged on traction housing upper face by High Strength Hydraulic bolt.
Further, gland 5 is fixed on long splined shaft 7 by screw, plays location to road wheel.
Further, utilize bolt 4 clamping platen 3, prevent the screw loosening on gland 5, improve the reliability of running gear.
Beneficial effect of the present invention is:
1) improve the compliance of coal-winning machine in face with complex.
2) adopt major axis output type structure, tractive unit shaft road wheel is directly meshed with pin row, reduces machine height and increases coal space.
3) structure of major axis output employing high-strength bolt pressure sheet compresses the screw combined pressure lid and major axis, prevents screw loosening, improves the reliability of running gear.
4) employing of novel low seam mining machinery " left-hand thread " formula running gear, reduce the requirement of coal-winning machine to drag conveyor glacing flatness and flexibility, reduce the labour intensity of workman, shorten the time of Operational preparation, improve the Homes Using TV of coal-winning machine, improve operating efficiency.

Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the present invention is further described.
Refer to Fig. 5-Figure 12, the novel low seam mining machinery of one " left-hand thread " the formula running gear of invention, mainly comprise guard shield 1, guide slip shoe 2, pressing plate 3, bolt 4, gland 5, pin rail 6, spline major axis 7, bearing support 8, road wheel 9 etc.
Road wheel 9 is directly connected in long splined shaft 7 end, engages with pin rail 6, reduces machine height, and increases coal space; Guard shield 1 is arranged on traction housing upper face by High Strength Hydraulic bolt, and guard shield 1 is provided with the boss 1a for support guide piston shoes 2, and boss 1a is circular arc, and arc gap is downward; Guide slip shoe 2 has annular brace circle 2a, annular brace circle 2a hanging sleeve is on described boss 1; Boss 1a, as the axis of rotation of guide slip shoe, enables guide slip shoe along its circumferential flexible rotating ± 5 ~ 10 °;
In addition between guard shield 1 and bearing support 8 for guide slip shoe reserves axial play, improve coal-winning machine and adapt to the bending ability of work plane that work plane rises and falls; Gland 5 is fixed on major axis 7 by screw, plays location to road wheel, utilizes bolt 4 clamping platen 3, prevents the screw loosening on gland 5, improves the reliability of running gear.
In sum, the novel low seam mining machinery of one " left-hand thread " the formula running gear that this practicality proposes, in low seam mining machinery " left-hand thread " formula running gear, achieve the rotation of guide slip shoe first and move axially, improve the compliance of coal-winning machine in face with complex, overcome " left-hand thread ' guide slip shoe of formula running gear cannot realize the technical barrier that rotates.
This running gear, adopt major axis output type structure, tractive unit shaft road wheel is directly meshed with pin row, reduces machine height and increases coal space.The structure of major axis output employing high-strength bolt pressure sheet compresses the screw combined pressure lid and major axis, prevents screw loosening, improves the reliability of running gear.The employing of novel low seam mining machinery " left-hand thread " formula running gear, reduce the requirement of coal-winning machine to drag conveyor glacing flatness and flexibility, reduce the labour intensity of workman, shorten the time of Operational preparation, improve the Homes Using TV of coal-winning machine, improve operating efficiency.
