Utilize Fig. 3 that the service procedure of the lift appliance of present embodiment is described below.At first, lift car 5 is stopped near the maintenance position of the regulation the superiors, service personnel 20 stands on the operation post 21, opens above the car open-close lid 9a of 8 peristome 9, in car 5 the lift well top apparatus is carried out upkeep operation.Operation post 21 used herein is accordion structures of setting up in car 5, folds up the internal side wall of folding and unfolding at car 5 when elevator moves at ordinary times.In addition, this operation post 21 has the mechanism that regulates the above-below direction height, can regulate the height of operation post according to the height of service personnel 20.Winch 13 and control panel 31, its upkeep operation object face 22 that carries out upkeep operation is configured in direction under the vertical.The wasted space minimum that the objective of the invention is to lift well 1 top, so need make above the car 8 with the lift well top that the gap of equipment is set is as far as possible little, therefore, the method for utilizing following explanation is calculated 8 distances that equipment are set with the lift well top above the car.
Fig. 4 is in the lift appliance of expression present embodiment, the state of the very fast operation of imagination lift car, the concept map of the action of the lift car when being used to this very fast operation is described, Fig. 4 (A) expression lift car rises with command speed, and counterweight pours the figure of the moment of energy disperser.In addition, after Fig. 4 (B) expression counterweight pours energy disperser, the end position when lift car further rises with force of inertia.
Elevator is during with the command speed lifting, and top 8 of lift car 5 is provided with the gap of equipment with the lift well top, and imagination must make car 5 with the lift well top device conflict is not set because of certain reason makes the occasions of lift car 5 very fast operations.In other words, 8 the gap of equipment is set as long as car 5 and lift well top are provided with more than the distance that equipment do not conflict when the very fast operation of car 5 above the car with the lift well top.
Here, shown in Fig. 4 (A), lift car 5 rises with command speed (V) in the way, and not slowing down because of certain reason continues the occasion that rises, pours energy disperser 11 towards the counterweight 10 that continues decline with car 5 opposite senses.Shown in Fig. 4 (B), pour by this, the tension force of the main rope 12 that in the past produced between car 5 and the counterweight 10 disappears.At this moment, the car 5 that rises with command speed (V) originally, because of force of inertia with this speed (V) as initial velocity and upwards takeoff.The amount of takeofing of this lift car 5 can be tried to achieve by following formula.
S＝V
2/2g
Wherein: (S) being the lift car amount of takeofing, (V) is the initial velocity (command speed) of lift car, (g) is acceleration due to gravity.
Therefore, by above-mentioned formula, as long as make above the car 8 and the lift well top gap between the equipment is set at least more than the amount of takeofing (S) of car 5, even just in case the occasion that car 5 moves in rising on the way with command speed (V) very fast, the state of affairs that also can avoid car 5 and lift well top that device conflict is set takes place.But, on the other hand,, guarantee to avoid when elevator moves very fast above the car 8 to be provided with on the basis in gap of device conflict with the lift well top in order to dwindle the wasted space at lift well top, require this gap as far as possible little.Because the amount of takeofing (S) that the gap of being tried to achieve by above-mentioned formula is a counterweight 10 to begin when pouring energy disperser 11, in order to reduce this gap as far as possible, service personnel 20 is the maintenance position during mobile car 5 in order to carry out upkeep operation, and preferably counterweight 10 just will be with before energy disperser 11 have contacted.In fact, need to be provided with surplus between the counterweight 10 of maintenance position and the energy disperser 11, but this surplus is got the amount of takeofing (S) about 20% just enough of car 5.
As mentioned above, above the car of maintenance position 8 with the lift well top gap of equipment is set, as long as be set in lift car 5 the amount of takeofing (S)～amount of takeofing (S) about 20%.Such as, command speed is the elevator of 120 meters of per minutes, when calculating the gap is actual, the amount of takeofing of car 5 (S) is about 20cm, considers surplus, as long as guarantee about 20～40cm in the gap.So, as shown in Figure 3, the height setting of operation post 21 is: when carrying out upkeep operation, service personnel 20 need not be above car 8 peristome 9 labour contractors stretch out, the elongation arm, the lift well top that hand just can contact winch 13 grades is provided with equipment, thus, even, can prevent that also the head of service personnel 20 and lift well top are provided with the equipment bump just in case car 5 moves very fast.
Below, Fig. 5 is the lift appliance of expression present embodiment, is the figure of the upkeep operation method of the elevator that is used to illustrate that command speed is big.
For command speed greater than 120 meters of per minutes, the elevator that belongs to so-called high-speed type, square being directly proportional and increasing of the amount of takeofing of above-mentioned lift car 5 (S) and speed, the elevator that command speed is big more, above the car 8 and the lift well top minimal gap increase required between the equipment is set.Even in such occasion, as shown in Figure 5, as long as with the height setting of operation post 21 be: when carrying out upkeep operation, service personnel 20 need not be above car 8 peristome 9 labour contractors stretch out, the lift well top that elongation arm hand just can contact winch 13 grades is provided with equipment, can carry out upkeep operation, thus, even just in case the occasion of car 5 very fast operations, neck just can prevent that head and lift well top are provided with the equipment bump as long as service personnel 20 contracts down.
In addition, in the present embodiment, operation post 21 is examples of setting up in lift car 5, and operation post 21 is not limited to the structure of setting up in car 5, the structure of moving into from the outside when also carrying out upkeep operation.Service personnel 20 is being stood and is being carried out operation among the figure, and certainly the height with operation post 21 improves, and service personnel 20 is seated and carries out operation and also can obtain identical effect.
Above embodiment has following effect.
