Abstract
The present invention discloses a kind of method of PVF films cladding drag-line cable body, the PVF films of PVF films progress drag-line Surface coating and two kinds of width that a kind of width is respectively adopted carry out the method for coating that drag-line surface one takes one, the width of PVF films is coated along the girth of cable body, and the width both sides of PVF films form overlap joint or non-overlapping.The method for coating of the present invention can make speed of application faster, more efficient, personal security is more secure and construction project expense is lower.
Description
Technical field
The invention belongs to technical field of civil engineering, and in particular to a kind of method of PVF films cladding drag-line cable body.
Background technology
Currently in order to improve the service life of drag-line, often in drag-line surface wrap PVF films, isolated by PVF films ultraviolet
Line, makes the cable body of drag-line have longer service life.Patent application such as Publication No. " CN101230559A " discloses one kind
Winding screw muscle method after inclined cable external surface winding PVF fluoride membrane adhesive tapes, this method are first carried out to Cable Stayed Steel tow
Hot extrusion high density polyethylene (HDPE), then spiral be wrapped one layer of PVF fluorinated film Protection glue band, the last winding screw again outside PVF adhesive tapes
Muscle.
For the mode of winding, the rotary speed that its speed constructed mainly is wound and two parameters of pitch of winding
Influence, due to need to be rotated together with winding film in work high above the ground and rotating disk, so rotary speed can not possibly be too fast, otherwise hold
It is also easy to produce danger；If increasing pitch, the width of winding film must be just increased, width, which increases, can then cause corrugation, can not be with rope
Body bonds together well.In addition, for longer suspension cable, completing the winding of the suspension cable of one needs multireel PVF films,
Due to causing the speed of walking slow using canoe, plus the replacement problem in view of often rolling up, it is also necessary to there are personnel to carry out high
Idle job.Therefore, it is low to wind efficiency, it is current on traffic to influence greatly, and the security risk of work high above the ground be present in personnel.
The content of the invention
The present invention asks for low construction efficiency, construction risk height etc. be present in existing PVF films winding Cable body method
A kind of topic, there is provided method of PVF films cladding drag-line cable body.
The present invention takes following technical scheme to realize above-mentioned purpose：
A kind of method of PVF films cladding drag-line cable body, it is characterised in that the length of PVF films matches with Cable body length,
Circumference of the broadside of PVF films along drag-line cable body is coated.This method is better than bonding with cable body using the tack of PVF films
Property, it is ensured that PVF films will not be split away off from cable body；Meanwhile the length of PVF films customizes according to Cable body length, winding
Membranous disc need not rotate, therefore the size for winding membranous disc is unaffected, so avoid multiple replacing winding membranous disc.
Preferably, the width of PVF films is more than the girth of drag-line cable body, and the broadside both sides of PVF films form overlap joint, overlapping area
No more than the 50% of cladding area, cladding stability of the PVF films to drag-line cable body is improved by overlapping mode.
Preferably, the width of PVF films is not more than the girth of drag-line cable body, and PVF film broadsides both sides form non-overlapping, clearance plane
20% of product no more than cladding area.When which can be used for drag-line cable body cleannes higher；To further enhance PVF films to drawing
The cladding intensity of rustling sound body, also it can wind threaded line in PVF films outer layer.
Preferably, it is secondary using the progress of PVF films again outside PVF films along Cable body length direction at interval of certain distance
Fixed, the spacing distance is 1-50 rice, so as to strengthen cladding stability of the PVF films to drag-line cable body.
Preferably, PVF films are two disks, and the width sum of two disk PVF films is not less than the girth of drag-line cable body, two disk PVF films
Formed at two and overlapped, often locate overlapping area no more than cladding area 50%.
The beneficial effects of the invention are as follows：
1st, improve speed of application and improve the efficiency of construction：It can be customized and twined according to the length of drag-line using clad type
Around the length of membranous disc, because winding membranous disc need not rotate, therefore the size for winding membranous disc is unaffected, avoid it is multiple more
Winding membranous disc is changed, so as to improve efficiency of construction.
2nd, weight of equipment is mitigated：Because the equipment needs of canoe are manned, therefore the specification of its equipment, weight compare
Greatly, changing to another drag-line from a drag-line for equipment needs to spend longer time, can be by equipment more using clad type
It is lightweight, more compact, it is also less to the demand of personnel.
3rd, the safety of workmen is improved：Due to during cladding, it is not necessary to which personnel carry out work high above the ground, substantially reduce
The high-altitude of personnel is dangerous.
4th, construction cost is reduced：Due to being optimized in terms of speed of application, efficiency of construction, personnel amount three, significantly
Reduce drag-line construction cost.
Brief description of the drawings
Fig. 1 is the structural representation of the present invention that Cable body formation overlap joint is coated using a disk PVF films.
Fig. 2 forms non-overlapping structural representation to be of the present invention using disk PVF films cladding Cable body.
Fig. 3 is the structural representation of the present invention that Cable body formation overlap joint is coated using two disk PVF films.
In figure, 1, drag-line cable body；2nd, PVF films；3rd, lap-joint；4th, seam.
Embodiment
The present invention is described in detail by 1-3 below in conjunction with the accompanying drawings.
As shown in figure 1, the invention provides a kind of method of PVF films cladding drag-line cable body, the length and Cable of PVF films
Body length is matched, and the circumference of the broadsides of PVF films along drag-line cable body is coated.This method using the tack of PVF films be better than with
The cementability of cable body, it is ensured that PVF films will not be split away off from cable body；Meanwhile the length of PVF films is according to Cable body length
Customization, winding membranous disc need not rotate, therefore the size for winding membranous disc is unaffected.So avoid multiple replacing winding
Membranous disc.
As shown in Fig. 2 the invention provides a kind of method of PVF films cladding drag-line cable body, it is right using a disk PVF films (2)
Drag-line cable body (1) is coated, and the circumference of the broadsides of PVF films (2) along drag-line cable body (1) is coated, the width of PVF films (2)
Equal to the girth of drag-line cable body (1), PVF films (2) width both sides form non-overlapping, seam (4) place gapless.Which is used to draw
When rustling sound body surface cleanness is higher, it is possible to reduce the dosage of PVF films.
As shown in figure 3, the invention provides a kind of method of PVF films cladding drag-line cable body, it is right using two disk PVF films (2)
Drag-line cable body (1) is coated, and the girth of the broadsides of PVF films (2) along drag-line cable body (1) is coated, the width of two disk PVF films
Sum is not less than the girth of drag-line cable body, and two disk PVF films are formed at two and overlapped, and often locates overlapping area no more than cladding area
50%.Which forms at two and overlapped, improve the stability of PVF films cladding by way of taking one in Cable body surface face one.
