Abstract
The invention relates to abrasion-resistant rake teeth for a railway ballast cleaning device, and belongs to the technical field of railway repair construction. The rate teeth comprise a substrate, wherein the substrate is provided with a rake handle and a tooth holder; the front end of the tooth holder is provided with a circular depression; the large end, with a conical tip, of a hard alloy tooth tip is inserted into the circular depression; and the circular depression is connected with the large fixedly. The abrasion-resistant rake teeth not only break through conventional materials and manufacturing processes of the rake, but also perform optimal design on the shape of the rake, thereby prolonging the service life remarkably and having prominent substantive characteristics and remarkable progresses compared with the prior art.
Description
Technical field
The present invention relates to a kind of rake teeth, the wear-resisting rake teeth of especially a kind of railway cleaning car belongs to the railway maintenance technical field of construction.
Background technology
Understand according to the applicant, the rake teeth that existing railway cleaning car uses is made of rabble arm 1 and coniform drag head 2 as shown in Figure 1, adopts spring steel material (for example 60Si2Cr) to be processed into overall structure, and hardness reaches HRC60 behind heat-treatment quenching.Adopt the rake teeth of this fabrication process to have certain abrasion resistance properties at the use initial stage, but through after the use of short time, the abrasion resistance properties of rake teeth just sharply descends, and coniform drag head is worn and forms circular-arc bulb, and length dimension significantly reduces, and lost basic cleaning effect.So application life is shorter, and the cleaning mileage only is about 5Km.Site operation needs frequent the replacing to scrap rake teeth, makes that sorting operation efficient is low, and the maintaining workload is big, and the labor strength height has been wasted a large amount of time and cost.
Retrieval is found, the Chinese patent application that application number is 89202909.9, name is called that " small ballast undercutting cleaner digger chain " and application number are 200720035156.9, name is called " screen scarifier digger chain rake teeth fixed structure " discloses the improvement of rake teeth structure respectively, yet these improvement are therefore irrelevant application life with the prolongation rake teeth mainly for the ease of changing (replacing that proves its use thus is frequent).
Summary of the invention
The objective of the invention is to: at the problem of above-mentioned prior art existence, a kind of wear-resisting rake teeth of railway cleaning car that can significantly improve application life is proposed, thereby help to improve the operation quality and the efficient of railway cleaning car, and reduce on-the-spot maintaining workload, reduce labour intensity.
In order to reach above purpose, the wear-resisting rake teeth of railway cleaning car of the present invention comprises matrix, described matrix is made of rabble arm and toothholder, it is characterized in that: described rake teeth also comprises the carbide alloy crown with the pointed shape of awl, it is recessed that the front end of described toothholder has circle, the big end of described crown insert described circle recessed in, be connected and fixed each other.Usually adopt soldering processes to be connected and fixed, also can take the circumstances into consideration to take other feasible fixedly connected mode.
Because the abrasion resistance of carbide alloy far is better than the quenching spring steel, so after adopting the present invention, prolong 5-7 doubly than original the application life of whole rake teeth, and effect is very remarkable.
The present invention further improves, and the big end external diameter and the recessed internal diameter of described circle of described crown match, the big end of described crown insert described circle recessed in, the recessed underrun soldering of the end face of described big end and described circle is connected and fixed.The big end external diameter of crown matches with the recessed internal diameter of circle and locatees when not only being convenient to assemble, and has formed the joint clearance of brazing of circumference after the assembling naturally, and the recessed underrun soldering of the end face of the big end of crown and toothholder circle has formed strength weld, guarantees reliable connection.
The present invention further improves, and the taper shape awl point of described crown is connected with the transition of big end by arc section, forms the streamlined conehead.Like this, the resistance in the time of can significantly reducing the ballast cleaning ballast, thus further reduce wear.
This shows that the present invention has not only broken through the traditional material and the manufacturing process of rake teeth, and its shape also carried out optimal design, thus significant prolongation application life, compared with prior art, have outstanding substantive distinguishing features and obvious improvement.
Description of drawings
The present invention is further illustrated below in conjunction with accompanying drawing.
Fig. 1 is the prior art constructions schematic diagram.
Fig. 2 is the structural representation of one embodiment of the invention.
Fig. 3 is the structural representation of second embodiment of the invention.
Fig. 4 is the structural representation of third embodiment of the invention.
The specific embodiment
Embodiment one
The wear-resisting rake teeth basic structure of railway cleaning car of present embodiment as shown in Figure 2, its matrix is made of rabble arm 1 and toothholder 2.The front portion of toothholder 2 has round platform 2-2, and this round platform links to each other with rabble arm 1 by the cylindrical section 2-3 that its bigger diameter end extends.The front end of round platform 2-2 has the recessed short cylindrical section 2-1 of formation circle.Crown 3 is the carbide alloy material, the sharp 3-1 of its conical awl is connected with big end 3-2 transition by arc section, form the streamlined conehead of bullet-shaped, the recessed internal diameter of big end 3-2 external diameter and short cylindrical section 2-1 circle matches, after in the insertion circle is recessed, the end face of big end 3-2 matches with round recessed bottom surface, by soldering crown 3 and toothholder 2 reliably is connected.
Facts have proved, after adopting present embodiment, because the most serious crown position of wearing and tearing changes the carbide alloy material into during rake teeth work, be connected to toothholder by soldering, therefore make the abrasion resistance properties of rake teeth greatly improve, the optimal design of crown shape reduces working resistance relatively in addition, the monnolithic case of rake teeth can keep for a long time, uniform wear, significantly prolonged application life, for the 6-8 of original rake teeth doubly, reduce the workload of changing rake teeth thus, reduced labour intensity, improved operating efficiency.
Embodiment two
The basic structure of the wear-resisting rake teeth of present embodiment railway cleaning car is close with embodiment one, and as shown in Figure 3, difference is that toothholder 2 has forward and backward round platform 2-2, the 2-4 that connects by cylindrical section 2-3.The front end of preceding round platform 2-2 has the recessed short cylindrical section 2-1 of formation circle.Back round platform 2-4 links to each other with rabble arm 1 by the cylindrical section that its bigger diameter end extends.
Embodiment three
The basic structure of the wear-resisting rake teeth of present embodiment railway cleaning car is also close with embodiment one, as shown in Figure 4, toothholder 2 front portions are round platform 2-2, and the front end of this round platform has the recessed short cylindrical section 2-1 of formation circle, and difference is that toothholder 2 directly links to each other with rabble arm 1 by the bigger diameter ends of round platform 2-2.Its advantage is that processing is simple, low cost of manufacture.
In addition to the implementation, the present invention can also have other embodiments.All employings are equal to the technical scheme of replacement or equivalent transformation formation, all drop on the protection domain of requirement of the present invention.
