First embodiment
At first the first embodiment of the present invention is described referring to figs. 1 through Fig. 3.
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 hoist cable winding work.In Fig. 1, use near the fixed type scaffold 2 assembling elevator car frame 1 hoist trunk top be arranged in the 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 is maintained on the retaining member 7 when assembling in the assembling of hoist trunk bottom.The top of counterbalanced weight framework is provided with counterweight block 8.Rope sheave 10 is installed on the winch 9.In addition, counterbalanced weight uses elevator car frame 1 to be provided with deflection sheave 11 and lift car with deflection sheave 12.
In hoist trunk is set before equipment and the coiling hoist cable, being used to reel and roller covering member 13 being installed on the face of hoist cable at each pulley and rope sheave earlier.When on counterbalanced weight usefulness deflection sheave 11 and lift car usefulness deflection sheave 12, roller covering member 13 being installed, use elevator car frame 1 to install, when on lift car lower pulley 5, roller covering member 13 being installed, use fixed type scaffold 2 to install.When on counterweight block 8 and rope sheave 10, roller covering member 13 being installed, install in the bottom of hoist trunk.
The end of one side of hoist cable 14 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 then at last earlier by lift car lower pulley 5.After the winding work of all hoist cables is finished, carry out the dismounting work of roller covering member 13.At this moment, increase the weight of elevator car frame 1, make behind the Heavy Weight of its weight ratio counterbalanced weight framework 6, utilize cucurbit to hang 3 elevator car frame 1 hung down, hoist cable 14 moves thereupon, and along with moving of hoist cable 14, each pulley and rope sheave rotate.
And, discharge the drg of winch 9 this moment in advance.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 is the vertical cross-section diagram of the hoist trunk of the state after the winding work of the installation of equipment and hoist cable finishes in the expression hoist trunk.After removing roller covering member 13, begin to assemble elevator cages 15, and in counterbalanced weight framework 6 load balance pouring weight 16.Remove fixed type scaffold 2, cucurbit afterwards and hang 3 and retaining member 7, the installation of elevator and hoist cable winding work finish.
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 the roller 17.In addition, also can use metal filament to wait and replace rubber tape.
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 roller covering member of no use covers, its reason is, when the coiling hoist cable, after discharging the drg of winch, because rope sheave and pulley can rotate freely, so when reeling first hoist cable, can under the state that does not almost have resistance, reel.And after first hoist cable reeled, because the resin on first hoist cable surface of winding and the metallic contact of roller, so the friction between hoist cable and the roller becomes greatly.Therefore, when reeling second hoist cable, first spline effect that hoist cable plays the rotation of 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 is provided with effective later on first hoist cable winding.Since second hoist cable, though rope sheave and pulley can not rotate freely the friction in the time of can using the roller covering member to reduce the hoist cable coiling.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 has played the spline effect on the roller, 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 hoist cable winding work is also convenient.
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,, be not mechanically to implement, but implement with electric means by control panel by being installed in brake rod on the drg etc. for safety., before control panel sets or before control panel energising, during the coiling hoist cable, can not discharge the drg of winch.
So, under the situation of the drg that can not discharge winch 9, because rope sheave can't rotate freely, so be necessary just to reduce friction force between hoist cable and the rope sheave since first hoist cable, in this case, the roller covering member of 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 when 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 under the situation that rotation stop device is installed on the pulley, be necessary to begin just to reduce friction between hoist cable and the 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 the lift car lower pulley shown in Figure 1 is 90 degree, so be that 90 degree are just enough with the angle initialization of roller covering member.Again, owing to around each deflection sheave and counterweight block, be provided with and be used for fixing each pulley shaft support etc., so for the ease of installing and removing, can use two winding angles be the roller covering member that used in 90 o'clock promptly two length to replace winding angle as the roller covering member of hoist cable groove periphery length 1/4 be the roller covering member of use 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 the roller 17 with through hole 19 and is fixed by making members such as rubber tape pass stationary member.Being used to of roller covering member, the reel groove of hoist cable was configured to circular trough, it be the reasons are as follows: the hoist cable groove that is processed to form on rope sheave is configured to circular trough and V-shape groove etc. according to the required tractive force of elevator, and be formed on hoist cable groove on the pulley in order to be controlled at the damage of hoist cable 14 in the 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.As a method that reduces the friction between roller covering member and the hoist cable is to reduce area of contact.As shown in Figure 7, be arranged to linearity, can suppress the area of contact between roller covering member 13 and the hoist cable, thereby can reduce friction by the hoist cable bottom land that will be installed in the roller covering member 13 on the roller 17.
The 6th embodiment
Fig. 8 represents another other embodiment of roller covering member of the present invention.The characteristics of present embodiment are that roller covering member 13 is arranged to the two-layer structure that is made of low friction layer 20 and high friction layer 21.The low friction layer 20 that wraps hoist cable adopts formations such as low friction resin such as fluorinated resin, ultra high molecular polyethylene and nylon.The face that contacts with roller is a high friction layer 21 owing to adopt the contour friction resin manufacture of rubber, thus be not easy the installation site skew from the roller, thus can more effectively carry out the winding work of hoist cable.
