Description
Technical field
The utility model is related to fall protection device for working at height, and in particular to a kind of subtracting for lifeline drop preventer
Shake device.
Background technology
The horizontal life line system of fall arrest is a kind of anchor, it is by anchor point holder and horizontal hawser (based on wirerope)
Composition, i.e., so-called horizontal lifeline, or referred to as safety line.This device is typically are permanently fixed in a structure, purport
Can safely be worked ensuring one or more people being likely to occur the high-altitude fallen, for they provide one it is more free
Activity space.It can be installed by modes such as straight line, curves.
Application No. is 201320169317.9 Chinese patent documents to disclose horizontal life line apparatus, and horizontal life is traditional thread binding
It sets for overhead horizontal movement operation and level fixed point operation, 1 one end of anchor point is mounted on fixed point, the other end and damping device
Connection；Damping device is connect with lifeline, and the lifeline other end is connect with anchor point 2, and anchor point 2 and fixing device are fixed on admittedly together
In fixed point, the generation of falling from high altitude is prevented.
Above-mentioned technical proposal makes the operating personnel of working at height to provide safeguard protection to operating personnel when working at height
There is the sense of security during moving horizontally, when operating personnel fall, lifeline is by from operating personnel's gravity
Pulling force, so that lifeline is deformed upon, damping device deformed upon by the pulling force of lifeline and absorb lifeline rebound generate
Impact force make operating personnel stablize hang in lifeline, operating personnel are in life when damping device directly determines to fall
Personal safety on line, therefore a kind of damping device of safety and stability of proposition is this patent problem to be solved.
Utility model content
In order to solve the above technical problems, the utility model proposes a kind of damper for lifeline drop preventer,
By only reducing the impact force generated when setting is fallen for absorption operation personnel with seat is abutted in sliding block, operating personnel is avoided to exist
The aerial bounce that vertical direction occurs reduces the risk that secondary injury occurs in the air for operating personnel after falling generation.
In order to achieve the above objectives, the technical solution of the utility model is as follows：A kind of subtracting for lifeline drop preventer
The shell that shake device includes the piston rod being connect with steel wire rope and is connect with anchor point, the piston rod are slided by elastic component
Inside the shell, one end of the shell is provided with the first connecting seat being connect with anchor point, and the piston rod is sheathed on shell for setting
The interior and described one end of piston rod far from the first connecting seat is provided with the second connecting seat connected for steel wire rope, the piston rod
One end far from the second connecting seat is provided with sliding block, and the one end of the shell far from the first connecting seat is provided with abutting seat, described
Elastic component setting sliding block with abuts between seat and makes sliding block far from abutting the movement of seat side.
By using above-mentioned technical proposal, steel wire rope is connect by damper with anchor point, and damper is existed by sliding setting
The impact force that the cooperation absorption operation personnel of piston rod in shell and setting elastic component inside the shell generate when falling, is being grasped
When falling as personnel, steel wire rope pulls piston rod to absorb the impact that the when of falling and occur generates by the deformation of elastic component to external extension
Power, in springback process, since the inner space of shell is limited, the rebound space of elastic component is limited, elastic in drop event
Part absorbs the energy generated when part is fallen, greatly reduces the rebound height of steel wire rope in springback process, reduces rebound
The distance of operating personnel's displacement in the process, occurs that operator occurs repeatedly to move up and down on steel wire rope after the generation that avoids falling, greatly
It is big to reduce the bounce of operating personnel in the air vertically on steel wire rope, it reduces operating personnel after falling generation and sends out in the air
The risk of raw secondary injury.
The utility model is further arranged to：The elastic component is the cylindrical spring of setting inside the shell, the cylinder bullet
Spring is arranged on the piston rod, and cylindrical spring is compressed spring.
By using above-mentioned technical proposal, compressed spring can absorb sliding block and abut the extruding occurred between seat, pass through
Compressed spring is absorbed pulls the impact force of steel wire rope since operating personnel fall, by the multiple deformation of compressed spring by the punching
Power release is hit, the bounce of operating personnel in the air vertically on steel wire rope is greatly reduced.
The utility model is further arranged to：The spring wire rectangular in cross-section of the cylindrical spring, when the cylindrical spring
After compressing, the spring wire of the cylindrical spring is bonded to each other.
By using above-mentioned technical proposal, when fall occur when, impact that the deformation quantity of cylindrical spring and while falling generate
Related, when the excessive and elastic range beyond cylindrical spring of the amount of shrinking, cylindrical spring loses elasticity, and rectangular section
Spring wire shrinks range when deforming upon by the mutual limit for abutting the cylindrical spring limited between spring wire, works as contraction
Cylindrical spring stops deformation after mutually being pasted to spring wire, and avoid causes cylindrical spring to fail since shrinkage is excessive, ensures
Cylindrical spring remains to keep the function of itself in the limiting case.
The utility model is further arranged to：The abutting seat includes the linkage section being connect with outer casing screw and is used for
The cover board of closure, the one end of the linkage section far from cover board are abutted with cylindrical spring, and the cover board is offered for piston rod
By slip hole.
By using above-mentioned technical proposal, abut seat by screw thread and cage connection, piston rod by slip hole with abut
Cylindrical spring, is sheathed on piston rod in assembling process and is packed into shell, then will be outer by abutting seat by seat sliding block cooperation
Shell seals；Abutting seat connect the maintenance for also allowing for later stage damper with outer casing screw simultaneously, and will abut seat and remove is replaceable circle
Column spring or piston rod.
The utility model is further arranged to：The linkage section offers the capillary groove of annular close to the side of cover board.
It can effectively be kept away after capillary groove is set by using above-mentioned technical proposal since shock absorber application is in outdoor environment
Exempt from droplet to enter in shell, ensures that the cylindrical spring in shell has metastable working space.
The utility model is further arranged to：The sliding block is threadedly connected on piston rod, the end of the cylindrical spring
It is bonded with sliding block.
By using above-mentioned technical proposal, sliding block by being threadably mounted on piston rod, when manufacture easy to produce sliding block with
The assembling of piston rod.
In conclusion the utility model has the following effects that：
Steel wire rope is connect by damper with anchor point, and damper is by sliding the piston rod and the setting that are arranged inside the shell
The impact force generated when the cooperation absorption operation personnel of elastic component fall inside the shell is significantly reduced operator after falling generation
The amplitude that member swings on a steel cord, greatly reduces risk of the operating personnel by secondary injury.
