Embodiment Construction

[0027] The present invention will be further described below in conjunction with embodiment (accompanying drawing):

[0028] The present invention takes the production of left-handed rope groove round steel or steel wire as an example, but does not limit the present invention.

[0029] as the picture shows figure 2 , image 3 , Figure 4 Therefore, the broken line rope groove reel of the present invention includes a smooth reel base 4, a left baffle plate 1 fixed on the left end of the reel base body and a right baffle plate 1-1 at the right end, as well as a base that surrounds the reel in a fixed manner. The broken line rope groove 8 composed of round steel or steel wire 3 wound on the surface of the reel with the base body; at the rope inlet end of the broken line rope groove, there is a supporting rope protrusion with a table width gradually narrowing from the width to the reel base body in a fixed way. Station 6 (see Figure 7 ), the end of the folded line rope groov...

Abstract

A drum with fold line grooves is characterized in that: the drum comprises a smooth drum substrate (4), a left baffle (1) and a right baffle (1-1) which are respectively fixedly connected on a left end and a right end of the drum substrate, and fold line grooves (8) composed of a cylinder material (3) winding on surface of the drum substrate by fixed connection; a gradually narrowing rope supporting boss (6) is arranged at a rope introducing end of the broken line grooves, and a gradually narrowing rope climbing platform (5) is arranged at a tail end of the broken line grooves; a fold back boss (7) is respectively arranged at narrow ends of the rope supporting boss and the rope climbing platform by closely fitting the left baffle and the right baffle; and the fold back boss is vertically arranged, perpendicular to a central axis of the drum substrate, has a cross section of a isosceles triangle structure, and has a plane containing bottom edges which is fixedly connected with lateral facade of the baffles.

Description

technical field [0001] The present invention relates to the field of hoisting technology, in particular to a winding reel of wire rope or cable suitable for metallurgy, coal mine, petroleum, chemical industry, construction, electric power construction, port loading and unloading, lifting transportation and other industries—broken wire rope Groove reel. technical background [0002] In the power construction industry, with the advancement of science and technology and the requirements of environmental protection and high efficiency, thermal power generating units continue to develop in the direction of large-scale, supercritical, and ultra-supercritical. From the popularity of 300MW thermal power generation units and the rise of 600MW thermal power generation units in the 1980s and 1990s to the popularization of 600MW thermal power generation units and the rise of 1000MW ultra-supercritical thermal power generation units in recent years, construction machinery, especially hoi...
