摘要： PROBLEM TO BE SOLVED: To provide a snow melting device capable of melting even firm snow coverage of snow, etc., dragged in the neighbourhood of a track of a railway. SOLUTION: It is furnished with a heat pipe 21 to generate heat, an upper part covering plate 30 to cover an upper part of the heat pipe 21 by a slant member made of metal, etc., and to guide snow melted water in a specified direction by melting snow by transmitting heat from the heat pipe 21 to snow by supporting snow on its surface and a heat insulating plate 40 and end part covering plates 41, 42 to seal air as a heat accumulating material by insulating heat except for heat transmitted to the upper part covering plate 30 out of heat from the heat pipe 21. Additionally, it is furnished with a temperature sensor, a controller to control starting and stopping of heating of the heat pipe 21 in accordance with detected temperature and a switch for electrification change-over.

摘要： PURPOSE:To enhance the safety through provision of mobility so that it does not influence the place with railroad rails, etc., where risk of electrical shortcircuiting exists and also equip the function to well work with a hardened or frozen snow to ensure enhancement of the snow removing ability. CONSTITUTION:A small-sized snow removing machine is equipped with a slide plate 0 capable of advancing while sliding on a snow surface, an auger 20 which rotates on the slide plate 10 and scratches in the snow deposited ahead in the slide plate advancing direction, and a cover 30 which covers the auger 20, whereby the snow raked in by the auger 20 is scattered away, and thus the snow removal is accomplished, wherein the sliding face 10a of the slide plate 10 is made of an electrically insulative material 13 while the side face 31 of the cover 30 located extremely aside is formed from electrically insulative material 32. Spiral vanes 22 are provided on the auger 20 protrusively ahead of the front edge and also downward from the sliding face 10a so that the vanes 22 contact the snow surface.

摘要： PURPOSE: To reshave a real and at a fixed angle by fixing a base plate on the upper face of a rail through a clamp mechanism so that a guide plate may be parallel to the end face of the rail, and attaching a motor base to a bracket at the front end of a slider, and firmly providing a motor on it, and detachably attaching a rotary blade to a rotating shaft. CONSTITUTION: A guide plate 2 is set so as to be parallel along the end of a rail 3, and a copying groove 5 on a slider 9 is moved along the plate 2. In this case, the side-facing bearing of the slider 9 is guided by a guide groove 6 provided on both the sides of the plate 2, and the downward bearing 8 of the slider 9 is rolled along the upper periphery of the rail 3. A bracket 10 is attached to the front end of the slider 9 so as to be adjustable in a longitudinal position and height, and a motor base 11 is firmly provided on the bracket 10 so as to be adjustable in an angle. A rotary blade 13 is detachably attached to the rotating shaft of the motor 12 attached to the motor base 11 and made adjustable in the longitudinal position, height and an angle to a rail joint. Thus, as the rotary blade 13 is made to follow the joint of the rail 3, a rail end is chamfered at a fixed angle, or only a rail flow is reshaved.
