Use Fig. 1 and Fig. 2, the details of the Weight measurement device 70 of the lifting body of the elevator used in the weight measurement method for the lifting body involved by above-mentioned present embodiment is described.
Weight measurement device 70 consists essentially of gravimetry device 7 and has the read out instrument 8 of display part 8a.And when needed, comprise the load dispersion plate 10 made of iron between floor 1a and gravimetry device 7 being inserted in Machine Room 1.
Gravimetry device 7 comprises: wedge-like portion 7a, 7b of being formed with rope clamping ditch 71; In inside, there is spring balance and using dip plane determination part 7c, 7d as compression face 7f, 7g; U-shaped metal fittings 11a, 11b, 11c, 11d (being generically and collectively referred to as 11 below) preventing causing because wedge-like portion 7a, 7b press compression face 7c, 7d occurring between determination part 7c and determination part 7d to expand described later; These U-shaped metal fittings 11 are fixed on the bolt 13 of determination part 7c, 7d made of iron of gravimetry device 7; In order to gravimetry device 7 is fixed on Machine Room 1 floor 1a (being load dispersion plate 10a, 10b in the present embodiment) and by welded and installed L-shaped metal fittings 12a, 12b, 12c, 12d in the back side of the compression face of determination part 7c, 7d; And bolt 13 (bolt shares in U-shaped metal fittings 11 and L-shaped metal fittings 12, but also can be different-diameter).
Then the details in each portion is described.Determination part 7c, 7d open compartment of terrain placing on load dispersion plate 10a, 10b compared to the diameter sky of main rope 6, make compression face 7f and compression face 7g in opposite directions.Compression face 7c, 7d become dip plane, and wedge-like portion described later 7a, 7b can be entered.Fig. 2 is with can the block diagram (main rope 6 is not shown) of gravimetry device 7 that forms of the mode of gravimetry, as shown in Figure 2, under the state after composition, compression face 7a, 7b run-off the straight, the interval between compression face 7a, 7b on top is broadened, and more narrower toward interval, bottom.The bottom again of compression face 7a, 7b becomes vertical component effect.
Fig. 3 is the birds-eye view of gravimetry device 7.Fig. 3 (a) is the birds-eye view of the gravimetry device 7 not comprising wedge-like portion 7a, 7b, and Fig. 3 (b) is the birds-eye view of wedge-like portion 7a, 7b.
In Fig. 3 (a), the compression face in determination part 7c, 7d shows for 7f, 7g.Circle shown by dashed lines is the position of the main rope 6 of the suspension craning cab 4 when gravimetry.The oad of gravimetry device 7 sets larger than the oad of peristome 1b of the floor 1a being formed at Machine Room 1.In addition, the size that the width dimensions of the rope width of the main rope 6 formed than the set by multiple rope is long is set to.Specifically, the inside dimensions at least between L-shaped metal fittings 12a ~ 12d is larger than the oad of peristome 1b, when working load dispersion plate 10a, 10b, need to make load dispersion plate 10a, 10b not with peristome 1b interfere.In addition, for the width dimensions of main rope 6, circle best-fit shown by dashed lines in Fig. 3 (a) has three, and as mentioned above, the interval of determination part 7c, 7d needs wider than the diameter of main rope 6, does not contact (can not produce this problem time wider than peristome 1b between load dispersion plate 10a, 10b) to make load dispersion plate 10a, 10b with main rope 6.
Fig. 3 (b) is the birds-eye view of wedge-like portion 7a, 7b, is formed and clamps ditch 71 with the rope of the radical equal number of main rope 6 that uses in measured elevator.In addition, by being pre-formed the rope clamping ditch 71 more than the radical of the main rope 6 used in measured elevator, thus the gravimetry of other elevators that can be more with the radical of main rope 6 shares.In addition, the diameter of rope clamping ditch 71 becomes the value slightly less than the diameter of main rope 6.Main rope 6 is sandwiched the rope clamping ditch 71 of this pair wedge-like portion 7a, 7b, be configured to make the dip plane of wedge-like portion 7a, 7b relative with compression face 7f, 7g of gravimetry device 7, start to carry out gravimetry.
Then the principle of Fig. 4 to the gravimetry in the present embodiment is used to be described (10a, 10b are not shown for load dispersion plate).Clamp main rope 6 and be configured to make dip plane 7h, 7i (angle of the lower roof of side is roughly equal with the angle between compression face 7f, 7g of determination part 7c, 7d) of wedge-like portion from mode relative to compression face 7f, 7g of a pair determination part 7c, 7d gravimetry to configuration 7a, 7b toward each other, described main rope 6 insertion is formed at the peristome 1b of the floor 1a of Machine Room 1.If main rope 6 moves downward because of the deadweight of car 4, then due to the effect of chock, wedge-like portion 7a and 7b can to the direction application force of fastening main rope 6, thus main rope 6 is fixed with the relative position of wedge-like portion 7a, 7b.7a, 7b are made up of friction materials such as band-type brake sheets in this wedge-like portion, therefore by effect fastening force to a certain degree, thus can fix main rope 6 firmly.Move downward while the dip plane of wedge-like portion 7a, 7b and compression face 7f, 7g of gravimetry device 7 abut against, when this moves stopping, the total weight of car 4 puts on compression face 7f, 7g.Be built-in with the weighing scales such as spring balance in the inside of determination part 7c, 7d, the aggregate value exported from the weighing scale of both sides is shown in the display part 8a of the read out instrument 8 shown in Fig. 1.
Then Fig. 1 and Fig. 2 is used to be described load dispersion plate 10a, 10b.If the intensity around the peristome 1b being arranged at the floor 1a of Machine Room 1 is sayed enough for supporting car 4, then can not working load dispersion plate 10a, 10b and directly Weight measurement device is set at floor 1a, but when load concentration, the intensity of peristome 1b periphery is as in problematic situation, working load dispersion plate 10a, 10b.As shown in Figure 2, under the base area of determination part 7c, 7d load assemble in when, under load dispersion plate 10a, 10b are layed in determination part 7c, 7d.Owing to being lay for the purpose of distractive load, therefore the base area of load dispersion plate 10a, 10b is larger than the base area of determination part 7c, 7d.
In addition, for this load dispersion plate 10a, 10b, utilize two bolt 13 fixed L shape metal fittings 12a, to resist the power that wedge-like portion 7a, 7b act on due to the load that is subject to from car 4 thus towards the direction of the space expansion made between determination part 7c and determination part 7d.Other L-shaped metal fittings are also identical.Namely, when by the placing of a determination part (such as 7c) in a load dispersion plate (such as 10a), similarly by another determination part (such as 7d) placing in another load dispersion plate (such as 10b), during in the load be subject to due to wedge-like portion 7a, 7b thus towards the direction applying power that determination part 7c, 7d expand each other, placing has the load dispersion plate of determination part interval each other also can expand.
In the present embodiment, owing to fixing determination part 7c and determination part 7d on two load dispersion plates 10a, 10b, therefore can also and the effect of U-shaped metal fittings 11 to combine the expansion at the interval preventing determination part 7c, 7d.
Then, the measuring method for the car 4 employing this Weight measurement device 70 is described.
Weight measurement device 70 is brought in Machine Room 1 under the state of taking apart (state that all bolts 13 are removed).Load dispersion plate 10a, 10b is arranged to make to be clipped between load dispersion plate 10a, 10b by peristome 1b on the direction that the direction of the main rope 6 of arrangement is vertical around peristome 1b.As shown in Figure 3, compression face 7f, 7g, towards main rope 6, make determination part 7c, 7d stand facing each other and are configured to make the orientation with main rope 6 parallel.Utilize bolt 13 that L-shaped metal fittings 12a ~ 12d is fixed on load dispersion plate 10a, 10b, these L-shaped metal fittings 12a ~ 12d is by being fixedly welded on the two ends of the back side (with the face at compression face 7f, 7g place for the surface) bottom of determination part 7c, 7d.Then, utilize bolt 13 that U-shaped metal fittings 11 are fixed on determination part 7c, 7d as shown in the figure.And wedge-like portion 7a, 7b dip plane is separately relative with compression face 7f, 7g, under the state that main rope 6 embeds rope clamping ditch 71 respectively, lentamente wedge-like portion 7a, 7b are placed on compression face 7f, 7g of determination part 7c, 7d.The wiring be connected with the weighing scale of determination part 7c, 7d is connected to read out instrument 8, completes the preparation of gravimetry.
The measuring method of car 4 has two kinds, is therefore described each method below.
Usually, balance block (clump weight) 5 is set to the weight weight than car 4.If unload brake equipment 3a in this condition, then car 4 can move upward.
Therefore, the first weight measurement method is following method: by the test weight placing of predetermined weight in car 4 to make car 4 than balance block 5 weight, measure car weight, afterwards from measurement result deduct test weight weight to calculate the weight of car 4.
Placing test weight in car 4, releasing braking device 3a.Car 4 declines because of deadweight.At first, main rope 6 slides downward in the rope clamping ditch 71 of wedge-like portion 7a, 7b, but when chock works gradually, stopping of sliding somewhere.Because brake equipment 3a is released, the not shown electrical motor of winch 3 is not energized and follows the movement of main rope 6, and therefore this state can think that all wt of car 4 all puts on Weight measurement device.The value shown by display part 8a of read out instrument 8 is now the weight of current car 4, and deduct the weight of test weight from this value after, the value that obtains is the weight of empty car 4.
Second weight measurement method is not by method that test weight placing is carried out in car 4.As mentioned above, prepare to perform gravimetry if be arranged at by Weight measurement device in Machine Room 1, then the direction making winch 3 decline towards car 4 lentamente rotates.Illustrated by above-mentioned first weight measurement method, the slip of main rope 6 stops somewhere, when winch 3 and the main rope 6 between wedge-like portion 7a, 7b are lax slightly, winch is stopped.The value being now shown in display part 8a is the weight of car 4.
In addition, as mentioned above, display part 8a shows the aggregate value of the measured value measured by each weighing scale of a pair determination part 7c, 7d being built in gravimetry portion 7.
Because weighing scale is spring balance, if compression face 7f, 7g pressurized of therefore determination part 7c, 7d of gravimetry device 7, correspond to weight and sink towards the direction vertical with face.
The weight measurement method of the lifting body of the elevator involved by the present embodiment formed like this and Weight measurement device, as mentioned above, owing to arranging gravimetry device 7 at the peristome 1b of the floor 1a being formed at Machine Room 1, car 4 is declined, utilize wedge-like portion 7a, 7b clamps main rope 6 and measures weight, namely, due to without the need to arranging larger fixed frame of the prior art as above, multiple oil-pressure jack, and push to platform etc., and adopt the simple structure of only operating weight measurement device 7 in Machine Room 1, and utilize the decline of car 4 to carry out gravimetry, therefore Weight measurement device can not be needed to moving into operation in elevator 2, installation exercise, and the field-strip after installing.
Thus, present embodiment can reduce the reduction of the service quality for elevator user.In addition, the constituting portion number of packages of Weight measurement device can suppress less by the present embodiment, can reduce the manufacturing expense of Weight measurement device.
In addition, be not that gripping apparatus is clamped with the contact of main rope 6 to measure weight by utilizing wedge-like portion 7a, 7b, thus the damage brought for main rope 6 can be suppressed in Min..
Then, use Fig. 5 that other embodiments of Weight measurement device are described.Fig. 5 is the birds-eye view of the Weight measurement device in other embodiments.In Weight measurement device in above-mentioned first embodiment, determination part 7c, 7d are independently parts, but collect two determination parts 7c, 7d in the present embodiment and become a determination part 14 made of iron.That is, one is formed to make to utilize transom 14h to connect determination part 14c, 14d to replace the U-shaped metal fittings of a side.From during top view, the part beyond compression face 14f, 14g is formed as U-shaped.
In the preparation of gravimetry, gravimetry device 14 is made to move to graphic position, to make compression face 14f, 14g parallel from the opening of U-shaped along the orientation of main rope 6.Then, U-shaped metal fittings 11a is installed to make the opening clamping U-shaped, utilizes not shown bolt to be fixed.In addition, not shown load dispersion plate 10a, 10b in the present embodiment.In addition, the weight measurement method of car 4 is identical with the first embodiment.
According to the present embodiment, installation radical, the dismounting radical of U-shaped metal fittings 11a can be reduced when preparation and the arrangement of gravimetry, therefore, it is possible to reduce flow chart number.And, owing to collecting two determination parts 14c, 14d, therefore relative with graphic U-shaped metal fittings 11a transom 14h becomes strength member, therefore, it is possible to fully resist the power two determination parts 14c, 14d pulled open because of wedge-like portion 7a, 7b when gravimetry.
In the above-described embodiment, enumerate and be described as the weight measurement method of the car 4 of lifting body and Weight measurement device, but the peristome 1c placing Weight measurement device passed through at the floor 1a being formed at Machine Room 1, utilize wedge-like portion 7a, 7b to clamp the main rope 6 on top near this Weight measurement device, thus the weight of another lifting body, i.e. clump weight 5 can be measured identically with above-mentioned embodiment.
