Abstract
The utility model belongs to the technical field of a coal cutter component, particularly relates to high-strength wearable guide boots, and solves the problems of rapture, abrasion and the like of the existing guide boots. The high-strength wearable guide boots comprise guide blocks with guide grooves, front plates of connecting holes and rear plates of connecting holes, wherein the front plates of connecting holes and the rear plates of connecting holes are fixed at the surfaces of the guide blocks; the front plates of connecting holes and the rear plates of connecting holes are high-strength plates; and the front plates of connecting holes and the rear plates of connecting holes are connected with the guide blocks by adopting forge welding. The high-strength wearable guide boots have the beneficial effects that the supporting and bearing capacity of a coal cutter is improved; the fracture frequency of the guide boots is reduced; and the strength and the abrasive resistance of the guide boots are improved; the reliability of a unit body is increased; and the fault rate is reduced.
Description
Technical field
The utility model belongs to the technical field of coal-winning machine parts, is specifically related to high-strength wearable guiding boots.
Background technology
Coal-winning machine is that the core of coal mining is implemented, and its major function is broken coal and coalings.Coal-winning machine in entire work process, static still motion state no matter, the weight of its complete machine is born by two level and smooth boots of rib side and two guiding boots adopting the sky side.Dynamic loading and friction when the guiding boots are born the coal-winning machine cut with walking, because the pressure that it bears is big, shock loading is inhomogeneous, very easily fracture and wearing and tearing have been buried hidden danger to safety coal mining.
At present, coal-winning machine guiding boots adopt steel-casting, intensity is low, rupture because being hit easily when the coal-winning machine coal cutting runs into dirt band, can't guarantee the correct engagement of coal-winning machine sprocket wheel and transporter pin rail, even break the chain rupture wheel off with the fingers and thumb, the application life of reducing equipment is again produced in influence, causes very big economic loss to manufacturing enterprise, and improved mining costs, influenced the normal development of national economy.
Summary of the invention
Easy fracture and the wear-resisting problem of the utility model in order to solve existing guiding boots provides high-strength wearable guiding boots.
The utility model adopts following technical scheme to realize:
High-strength wearable guiding boots, comprise plate behind the guide pad with direction recess, the connecting hole header board that is fixed on the guide pad upper surface and the connecting hole, plate is high-strength plate behind described connecting hole header board and the connecting hole, adopt the smithwelding structure behind described connecting hole header board, the connecting hole between plate and the guide pad, be provided with wearing layer at the inner surface of described direction recess.
The guiding boots adopt the smithwelding structure, cooperate corresponding heat treatment, and the contact site uses forged material and makes intensity and abrasion resistance improve simultaneously through Overheating Treatment, and suitably adjust guiding boots swing gap, avoid fracture.
The utlity model has following beneficial effect:
Improve support and the supporting capacity of coal-winning machine, lowered guiding boots fracture frequency, improved intensity and the abrasion resistance of guiding boots, increased the reliability of unit itself, reduced fault rate.
Description of drawings
Fig. 1 is schematic diagram of the present utility model;
Among the figure: plate behind the 1-connecting hole; 2-connecting hole header board; The 3-guide pad; The 4-wearing layer; The 5-direction recess.
The specific embodiment
By reference to the accompanying drawings the specific embodiment of the present utility model is described further.
As schematically shown in Figure 1, high-strength wearable guiding boots, comprise plate 1 behind the guide pad 3 with direction recess 5, the connecting hole header board 2 that is fixed on guide pad 3 upper surfaces and the connecting hole, plate 1 is high-strength plate behind described connecting hole header board 2 and the connecting hole, adopt the smithwelding structure behind described connecting hole header board 2, the connecting hole between plate 1 and the guide pad 3, be provided with wearing layer 4 at the inner surface of described direction recess.
The guiding boots adopt the smithwelding structure, cooperate corresponding heat treatment, and the contact site uses forged material and makes intensity and abrasion resistance improve simultaneously through Overheating Treatment, and suitably adjust guiding boots swing gap, avoid fracture.
The guiding boots used more than half a year, after the wearing and tearing of guiding boots groove 5 upper surfaces, can reuse at guiding boots groove 5 upper surfaces weldering wear-resisting steel plate or with the wear resistance electrode weldering is flat, and the boots that lead like this can use some months again.
