Description
Technical Field
The utility model relates to an aerial working prevents weighing down technical field, particularly, relates to a middle part string of some for horizontal lifeline device.
Background
Along with the increasing emphasis on the safety of high-altitude operation, the horizontal lifeline device is increasingly applied to the field of marginal operation of bridge crane rails and the like of industrial plants and main plants of hydropower stations.
The publication of national standard GB 38454 and 2019 Fall protection horizontal life line device standardizes the design and test method of the horizontal life line device.
The middle hanging point is installed in the middle of the horizontal life line device to reduce installation span and prevent the overlarge falling distance caused by the overlarge suspension amount of the steel wire rope. The traditional middle hanging point mainly aims at a single-rope horizontal lifeline device and cannot be suitable for the requirement of a double-rope horizontal lifeline device formed by taking a double-strand steel wire rope as a main body. Compared with the traditional single-rope horizontal lifeline device, the double-rope horizontal lifeline device has higher strength and reliability and can allow more intensive workers to operate in a centralized manner. The traditional middle hanging point mainly uses a spring washer to increase friction force so as to prevent looseness; due to the fact that the installation parts are added, construction difficulty in the actual high-altitude operation construction process is increased, and the possibility of neglected installation is increased.
Therefore, it is of practical significance to develop a middle hanging point suitable for the double-rope horizontal lifeline device.
SUMMERY OF THE UTILITY MODEL
The utility model aims at providing a middle hanging point which is used for a double-rope horizontal lifeline device, the structure is formed in an integrated way, and the structure is simple; the problems that the movable anchor point is unsmooth in hanging through the middle and the construction is inconvenient are solved.
The purpose of the utility model is realized through the following technical scheme:
the utility model provides a middle part hangs some for two horizontal life line devices of restricting, including supporting flat board, support riser and elastic fixation bottom plate, the both sides of supporting flat board are equipped with the installation pipe that is parallel to each other, the upper portion of supporting the riser is connected support dull and stereotyped middle part, the sub-unit connection of supporting the riser the elastic fixation bottom plate, elastic fixation bottom plate below both sides are equipped with the contact arch that is parallel to each other.
As right the further improvement of middle part hanging point, the contained angle has between support riser and the elastic fixation bottom plate, the contained angle be 92 ~ 100.
As right the further improvement of some is hung at the middle part, the tip of installation pipe has first chamfer, chamfer angle be 3 ~ 10.
The support is perpendicular on the flat board the both sides of installation pipe have the second chamfer, chamfer angle be 5 ~ 15.
As right the utility model discloses the further improvement of point is hung at the middle part, set up a mounting hole on the elastic fixation bottom plate, the mounting hole be the slotted hole.
During installation, the middle hanging point is installed on a concrete structure or a steel structure through the installation hole by using an expansion bolt or a bolt group; the contact bulge contacts the mounting plane first, and a long groove-shaped space is formed below the elastic fixing bottom plate, and the elastic fixing bottom plate generates elastic deformation along with the increase of the screwing torque, which is equivalent to the action of a spring washer. Along with the change of the elastic deformation quantity, the obtuse angle between the supporting vertical plate and the elastic fixing base can be reduced by a certain angle.
The application provides a middle hanging point which is suitable for a double-rope horizontal lifeline device; the movable anchor point can smoothly pass through the middle hanging point by arranging the support flat plate and the chamfer angle of the installation pipe; the elastic fixing bottom plate is arranged to ensure reliable fixing and facilitate construction.
