Abstract

The invention discloses a chain saw guide plate for special chain saws used for cutting brick masonry walls, stones, thin metal plates and the like. The chain saw guide plate comprises a guide plate body, a guide chain device, a chain guide groove and a cooled water conveying channel. Because the cooled water conveying channel is arranged on the guide plate body, heat as well as accumulated dusts and impurities of the cut objects and a saw chain can be reduced, the abrasion of the guide plate and the chain is reduced, and the service life of the chain saw is improved. The invention is especially suitable for rescuing requirements under severe environment of earthquake relief work, fire fighting and the like.

Description

Chain saw guide plate
Technical field
The present invention relates to a kind of chain saw, particularly relate to the guide plate that extraordinary chain saws such as cutting brick masonry wall, stone, metal sheet are used.
Background technology
Extraordinary chain saw is widely used in cutting high rigidity materials such as brick masonry wall, stone, metal sheet, use light, overcome dish saw formula cutting machine and take up space greatly, shortcoming such as depth of cut is shallow can be used for the first aid needs under the adverse circumstances such as common engineering cutting and earthquake relief work, fire-fighting.The chain saw of Ying Yonging has two kinds in the market, a kind of guide plate is a guide-roller type, the patent No. is " 03209864.2 ", name is called the Chinese utility model patent of " a kind of electric chain saw guide plate ", more typical structure is disclosed, this guide plate is welded into one through point by the inner guide plate of the bigger undersized of outer guide plate therebetween of two sizes and forms an overall structure, in the guided wheel slot that guide plate one end forms a sprocket wheel is housed, adopt the chain saw of this structure, because saw chain high load capacity during sawing, run up, and environment is abominable, dust and tiny sand grains enter in the sprocket assembly easily, causing that sprocket wheel is stuck can't transmission or drive disk assembly wear out failure, causes sawing work to stop, and often needs to change parts, inefficiency, the especially rescue time of waste preciousness when rescue and relief work; Deficiency at last kind guide plate, the patent No. is " 200820084178.9 ", name is called the Chinese utility model patent of " a kind of chain saw guide plate ", a kind of monoblock type chain saw guide plate is disclosed, it comprises the guide plate body, thereby the guide plate body is provided with the guide rail that the guide plate groove forms both sides, guide rail comprises postmedian guide rail and circular-arc front slideway, fromer rail is provided with wearing layer, the inner surface of wearing layer is concordant with the guide rail inner surface, the upper and lower surface of wearing layer is connected with the postmedian guide rail is smooth, though adopt the chain saw guide plate of this structure to overcome the above-mentioned shortcoming of guide-roller type guide plate, the guide plate life-span is to some extent along long, but because the chain saw of above-mentioned two kinds of structures its cooling water when cutting is given from the guide plate outside, cooling effect is poor, particularly to the cutting brick masonry wall, stone, during high rigidity materials such as metal sheet between chain and guide rail the friction and adstante febre can not be effectively to guide rail, chain and be cut object and cool off, thereby can not effectively reduce the wearing and tearing of chain and guide rail, reduced the service life of guide rail and chain, during simultaneously owing to work, the operating mode complexity, cutting swarf, dusts etc. have easily advanced between chain and guide rail, can not in time clear up, aggravate the wearing and tearing between guide rail and chain, reduced the life-span of guide plate and chain equally.
Summary of the invention
The objective of the invention is under adverse circumstances such as high speed wearing and tearing, HI high impact, complex stress, using between chain in the prior art and guide plate, because of friction is generated heat easy to wear, influence the deficiency in the service life of guide plate and chain, provide a kind of and can effectively reduce the chain saw guide plate that weares and teares between chain saw guide plate and chain, thus the life-span of improving chain saw guide plate and chain saw.
