Abstract
The utility model relates to an automatic-releasing fall pulley, which comprises a fall pulley and an automatic-releasing suspension loop connected to the upper end of the hook of the fall pulley through a suspension loop connection rod. The automatic-releasing function is added in the utility model, which ensures that the fall pulley becomes an electrified special tool with automatic suspension and releasing function. The added side pulley wheels ensure that the fall pulley can randomly move on a conducting wire, thereby facilitating reparation in deferent positions of the conducting wire and effectively increasing working efficiency.
Description
Technical field
The utility model relates to a kind of fall coaster that comes off automatically.
Background technology
Present existing coaster does not have automatic wire-off device, the work relatively difficulty that finishes when coming off, and coaster when side direction moves on lead friction force bigger, but also cause the lead breakage easily.
Summary of the invention
It is lightly flexible that technical problem to be solved in the utility model provides a kind of structure, hangs easily the fall coaster that comes off automatically that comes off easily after hours of difficult drop-off behind the hanging wire.
The technical solution of the utility model is as follows:
The utility model comprises fall coaster and the link that comes off automatically that is connected with fall coaster hook upper end by the link connecting rod.
One end of the utility model link connecting rod is hinged with fall coaster upper end mutually by rotating shaft.
The utility model good effect is as follows: the utility model has increased the function that comes off automatically, make the fall coaster really become a kind of charged special tool with the automatic suspension and the function that comes off, utilize newly-increased side direction pulley can make the fall coaster mobile with being intended on the lead, make things convenient for different parts maintenance on the lead, effectively increase work efficiency.
Description of drawings
Accompanying drawing 1 is the utility model structural representation;
Accompanying drawing 2 is the utility model running condition scheme drawing.
In the accompanying drawings: 1 pulley, the big rope of 2 insulation, 3 fall coasters, 4 gib head apertures, 5 insulate marlines, 6 rotating shafts, 7 link connecting rods, 8 come off automatically link, 9 side direction pulleys.
The specific embodiment
As shown in drawings, the dropping structure voluntarily that constitutes by link connecting rod 7 and the link 8 that comes off automatically that the utility model has increased that corrosion-resistant steel makes, an end of dropping structure link connecting rod 7 is hinged with fall coaster 3 upper ends mutually by rotating shaft 6 voluntarily, can come back rotation, the other end of link connecting rod 7 has the link 8 that comes off automatically, as shown in Figure 2, the big rope 2 of insulation passes from the pulley 1 and the link 8 that comes off automatically simultaneously during use, when needs during with 3 off-lines of fall coaster, be stuck in link 8 places that come off automatically after the A end knotting of the big rope 2 of insulation, by the other end that draws the big rope 2 of insulation make voluntarily dropping structure drive fall coaster 3 from the lead automatically rotation come off.
The utility model has installed a side direction pulley 9 additional in fall coaster 3 and lead contact portion, reduced the friction force that is produced when fall coaster 3 slidably reciprocates on lead so greatly, the coaster before having avoided damages the possibility of lead because there not being the sidesway pulley.
It is lightly flexible that the utility model fall coaster 3 has had structure, hang easily, the advantage of difficult drop-off behind the hanging wire, as shown in Figure 2, when the utility model needs hanging wire to use, penetrate insulation marline 5 from gib head aperture 4 earlier, it is standby that one end of insulation marline 5 binds the back, the other end of insulation marline 5 was thrown lead, pulley 1 penetrates the big rope 2 of insulation, then by drawing insulation marline 5 that 3 pull-ups of fall coaster are hanging on the lead, hangs up properly the back and utilizes the big rope 2 of insulation to rise hanging basket or other hanging wire instrument that has rope ladder, after hanging basket or other hanging wire instrument hang, operating personnel's operation of can ascending stair reaching the standard grade.When needs during with 3 off-lines of fall coaster, be stuck in link 8 places that come off automatically after the A end knotting of the big rope 2 of insulation, by the other end that draws the big rope 2 of insulation make the link 8 that comes off automatically drive fall coasters 3 automatically rotation come off.The utility model has increased the function that comes off automatically, makes the fall coaster really become a kind of charged special tool with the automatic suspension and the function that comes off.Utilize newly-increased side direction pulley 9 can make the fall coaster mobile, make things convenient for different parts maintenance on the lead with being intended on the lead.
