The first embodiment
At first referring to figs. 1 through Fig. 3, the first embodiment of the present invention is described.
The vertical cross-section diagram of the hoist trunk when Fig. 1 represents to use the hoist cable method for winding as one embodiment of the invention to carry out the operation of hoist cable coiling.In Fig. 1, use near the fixed type scaffold 2 assembling elevator car frame 1 hoist trunk top that is arranged in hoist trunk, this elevator car frame 1 is hung 3 by cucurbit and is suspended in midair from guide rail 4.The bottom of elevator car frame 1 is equipped with lift car lower pulley 5.In addition, counterbalanced weight framework 6, in the assembling of hoist trunk bottom, is maintained on retaining member 7 when assembling.The top of counterbalanced weight framework is provided with counterweight block 8.Rope sheave 10 is arranged on winch 9.In addition, counterbalanced weight arranges with deflection sheave 12 use elevator car frame 1 with deflection sheave 11 and lift car.
Before equipment and coiling hoist cable, elder generation is at the installation roller covering member 13 on the face of coiling hoist cable that is used for of each pulley and rope sheave in hoist trunk is set.While on counterbalanced weight use deflection sheave 11 and lift car use deflection sheave 12, roller covering member 13 being installed, use elevator car frame 1 to install, while on lift car lower pulley 5, roller covering member 13 being installed, use fixed type scaffold 2 to install.While on counterweight block 8 and rope sheave 10, roller covering member 13 being installed, in the bottom of hoist trunk, install.
The end of one side of hoist cable 14, first by lift car lower pulley 5, then, by lift car deflection sheave 12, rope sheave 10, counterbalanced weight deflection sheave 11 and counterweight block 8, is fixed on the wall of hoist trunk finally.After the coiling operation of all hoist cables is completed, carry out the dismounting work of roller covering member 13.At this moment, increase the weight of elevator car frame 1, after making the Heavy Weight of its weight ratio counterbalanced weight framework 6, utilize cucurbit to hang 3 elevator car frame 1 is hung down, hoist cable 14 moves thereupon, along with the movement of hoist cable 14, and each pulley and rope sheave rotation.
And, discharge in advance the drg of winch 9 this moment.Along with each pulley and rope sheave are further rotated, hoist cable 14 contacts with the face that roller covering member 13 is not set, and can remove roller covering member 13 thus.
Fig. 2 means the vertical cross-section diagram of the hoist trunk of the state after the coiling end of job of the installation of equipment in hoist trunk and hoist cable.After removing roller covering member 13, start to assemble elevator cages 15, and at the interior loading counterweight block 16 of counterbalanced weight framework 6.Remove afterwards fixed type scaffold 2, cucurbit and hang 3 and retaining member 7, the installation of elevator and the end of job of hoist cable coiling.
Fig. 3 represents an embodiment of roller covering member of the present invention.It is the part of 180 degree that this roller covering member 13 covers as the winding angle in the hoist cable groove of the roller 17 of rope sheave and pulley one example.Utilization is passed the stationary members such as rubber tape 18 that are processed to form the through hole on the roller covering member roller covering member is fixed on roller 17.In addition, also can replace rubber tape with metal filament etc.
Figure 3 illustrates the roller of three hoist cables of reeling, wherein two hoist cable grooves cover with the roller covering member, and another hoist cable groove does not cover with the roller covering member, its reason is, when the coiling hoist cable, after discharging the drg of winch, because rope sheave and pulley can rotate freely, so can reel almost not having under resistant state when reeling first hoist cable.And after first hoist cable reeled, because the resin on first hoist cable surface of winding contact with the metal surface of roller, so the change of the friction between hoist cable and roller greatly.Therefore, when reeling second hoist cable, first hoist cable plays the spline effect that the rotation to rope sheave and pulley is fixed.Because the rotation of rope sheave and pulley is fixed, so the roller covering member there is no need to cover the whole circumference of rope sheave and pulley, and the coiling scope that only need cover hoist cable gets final product.
Therefore, the roller covering member of Fig. 3 arranges effective first hoist cable winding later.Since second hoist cable, although rope sheave and pulley can not rotate freely, the friction in the time of can reducing hoist cable and reel with the roller covering member., at this, be illustrated as example with the roller that uses three hoist cables, but the use radical of hoist cable is not limited in three.
When the replacing operation of carrying out hoist cable, if only change a hoist cable, because original hoist cable on roller has played the spline effect, so use the effective of the roller covering member only cover a hoist cable groove.
The winding angle that roller covering member 13 is formed in the hoist cable groove that covers roller 17 is the shape of the part of 180 degree, the length that is to say roller covering member 13 is half of girth of hoist cable groove, so easy for installation, and the dismounting operation after the end of job of hoist cable coiling is also convenient.
The second embodiment
Fig. 4 represents other embodiment of roller covering member of the present invention.Winding angle in the hoist cable groove of these roller covering member 13 covering rollers 17 is the parts of 180 degree, and covers the hoist cable groove of all coiling hoist cables.Be arranged on the occasion of hoist trunk bottom at winch, when discharging the drg of winch,, for safety, be not mechanically to implement by being arranged on brake rod on drg etc., but by control panel, with electric means, implement., during the coiling hoist cable, can not discharge the drg of winch before control panel sets or before control panel energising.
So, in the situation that can not discharge the drg of winch 9, because rope sheave can't rotate freely, so be necessary just to reduce friction force between hoist cable and rope sheave since first hoist cable, in this case, the roller covering member of the present embodiment is used for rope sheave 10 and can obtains good result.In addition, when the coiling hoist cable, in order to prevent just in case hand while leaving hoist cable roller at the effect backspin of the weight of hoist cable then cause hoist cable to fall at a high speed, and in the situation that rotation stop device is installed on pulley, be necessary to start just to reduce friction between hoist cable and pulley from first hoist cable of reeling, in this case, roller covering member shown in Figure 4 is used for pulley and can obtains good effect.
The 3rd embodiment
Fig. 5 represents another other embodiment of roller covering member of the present invention.Because the winding angle of the hoist cable in lift car lower pulley shown in Figure 1 is 90 degree, so with the angle initialization of roller covering member, be that 90 degree are just enough.Again, owing to being provided be used to fixing each pulley shaft support etc. around each deflection sheave and counterweight block, so for the ease of installation and removal, can with two winding angles be the roller covering member used in 90 o'clock namely two length roller covering member that is hoist cable groove periphery length 1/4 to replace winding angle be the roller covering member that used in 180 o'clock.
The 4th embodiment
Fig. 6 represents another other embodiment of roller covering member of the present invention.Roller covering member 13 directly overlaps with roller 17, and this roller covering member 13 is wrapped on roller 17 and is fixed with through hole 19 by making the members such as rubber tape pass stationary member.The groove that is used for the coiling hoist cable of roller covering member is configured to circular trough, it be the reasons are as follows: the hoist cable groove tractive force required according to elevator that is processed to form on rope sheave is configured to circular trough and V-shape groove etc., and be formed on hoist cable groove on pulley in order to be controlled at the damage of hoist cable 14 in minimum scope, generally be configured to circular trough.Because roller covering member 13 does not need tractive property, so preferably be arranged to circular trough.
The 5th embodiment
Fig. 7 represents another other embodiment of roller covering member of the present invention.To reduce area of contact as a method that reduces the friction between roller covering member and hoist cable.As shown in Figure 7, by the hoist cable bottom land that will be arranged on the roller covering member 13 on roller 17, be arranged to linearity, can suppress the area of contact between roller covering member 13 and hoist cable, thereby can reduce friction.
The 6th embodiment
Fig. 8 represents another other embodiment of roller covering member of the present invention.The characteristics of the present embodiment are that roller covering member 13 is arranged to the two-layer structure that consists of low friction layer 20 and high friction layer 21.The low friction layer 20 that wraps hoist cable adopts the formations such as low friction resin such as fluorinated resin, ultra high molecular polyethylene and nylon.With the face of roller contact be high friction layer 21 owing to adopting the contour friction resin manufacture of rubber, so be not easy from the installation site skew on roller, thereby can more effectively carry out the coiling operation of hoist cable.
Abovely for the roller covering member, exemplified various embodiments, but the present invention is not limited in above-described embodiment, as long as can be arranged between roller and resin coating hoist cable the friction that reduces between roller and resin coating hoist cable, can use easier for example tabular low friction member, also can use from banded coiled material and cut required length and the low friction member that forms, the present invention can suitably be out of shape as required in application.
