Description

Technical Field

[0001] The present invention relates to an adjustment method for adjusting the weight balance of an elevator car by attaching weights to the elevator car, etc.

Background Art

[0002] There is an elevator in which a car is moved up and down while a guide shoe installed on the car slides on a guide rail extending vertically in a hoistway. In such an elevator, since the center of gravity of the car and the position where the main rope suspends the car do not completely coincide, the car tilts. As a result, one surface of the guide shoe contacts the guide rail, and when passing through the step of the guide rail, the car vibrates and a collision sound occurs due to a sudden force. The force acting between the guide shoe and the guide rail increases as the center of gravity of the car deviates from the position where the main rope suspends the car, so the above sudden force increases. Therefore, weights are attached to the car to make the center of gravity of the car coincide with the position where the main rope suspends the car.

[0003] Here, in some of the above elevators, a traveling cable for supplying power to the car and communicating between a control device installed in the car and an elevator control panel, a compensation rope for compensating for the change in the weight of the main rope accompanying the up and down movement of the car, etc. may be connected to the lower end of the car. In such a case, since the suspension load of the traveling cable and the compensation rope on the car changes as the car moves up and down, the position of the center of gravity of the car changes. Therefore, it is preferable to reduce the maximum value of the force acting between the guide shoe and the guide rail by adjusting the weight and installation position of the weight so that the center of gravity of the car becomes the position where the main rope suspends the car at the intermediate position in the vertical direction in the hoistway.

[0004] Patent Document 1 describes a device that measures the distance to a guide rail and displays the measured distance, and it is described that workers attach adjustment weights while looking at the display. [Prior art documents] [Patent Documents]

[0005] [Patent Document 1] Japanese Patent Publication No. 2007-008674 [Overview of the Initiative] [Problems that the invention aims to solve]

[0006] However, determining the appropriate weight and installation location for the weights requires trial and error, which is time-consuming. Therefore, there is a need for a technology that can easily determine the weight installation conditions.

[0007] One aspect of the present invention aims to realize an adjustment method that allows for the determination of weight mounting conditions in a simple manner. [Means for solving the problem]

[0008] To solve the above problems, an adjustment method according to embodiment 1 of the present invention is an adjustment method for adjusting the weight balance of an elevator car by attaching a weight to the elevator car, in an elevator that raises and lowers an elevator car while sliding a guide shoe installed on the elevator car against a guide rail extending vertically in a hoistway, wherein when the elevator car is moved from one end of the hoistway to the other end, the first state in which one surface of the guide shoe is sliding against the guide rail changes to the other surface of the guide shoe The method includes: a detection step of detecting a transition position in which the posture of the elevator car transitions to a second state in which it is sliding; a first calculation step of calculating a first distance between the transition position and an intermediate position in the vertical direction of the elevator shaft; a second calculation step of calculating the magnitude of the load connected to the lower end of the elevator car at the transition position; and a condition determination step of determining the mounting conditions of the weight based on the first distance, the magnitude of the load, and the suspension position to which the rope that raises and lowers the elevator car is connected when viewed from above.

[0009] According to the above configuration, the conditions for attaching the weights can be determined simply by raising or lowering the elevator car once from one end of the hoistway to the other, and also by detecting the transition position. Therefore, the conditions for attaching the weights can be determined in a simple manner.

[0010] The adjustment method according to aspect 2 of the present invention may be configured such that, in aspect 1, the detection step is terminated when it is detected that the posture of the elevator car has changed.

[0011] With the above configuration, the conditions for attaching the weight can be determined without moving the elevator car 1 to the other end.

[0012] The adjustment method according to embodiment 3 of the present invention may be configured such that, in embodiment 1 or 2 above, in the detection step, a second distance between the guide rail and the distance sensor is measured using a distance sensor installed in the elevator car, and the position where the second distance changes is detected as the transition position.

[0013] With the above configuration, when a distance sensor is used, it is easier to detect changes in the second distance, thus enabling more accurate detection of the transition position.

[0014] To solve the above problems, an information processing device according to aspect 4 of the present invention is an information processing device for determining the mounting conditions of a weight attached to the elevator car in order to adjust the weight balance of the elevator car, in an elevator that raises and lowers the elevator car while sliding a guide shoe installed on the elevator car with respect to a guide rail extending vertically in the hoistway, when the elevator car is moved from one end of the hoistway to the other end, from a first state in which one surface of the guide shoe is sliding against the guide rail to the other surface of the guide shoe The system includes: an acquisition unit that acquires information on the transition position when the posture of the elevator car transitions to a second state in which the surface slides on the guide rail; a first calculation unit that calculates a first distance between the transition position and an intermediate position in the vertical direction of the elevator shaft; a second calculation unit that calculates the magnitude of the load connected to the lower end of the elevator car at the transition position; and a condition determination unit that determines the mounting conditions for the weight based on the first distance, the magnitude of the load, and the suspension position to which the rope that raises and lowers the elevator car is connected when viewed from above. The above configuration provides the same effects as in embodiment 1.

[0015] To solve the above problems, the information processing apparatus according to aspect 5 of the present invention is a control program for causing a computer to function as the information processing apparatus described in aspect 4, and is a control program for causing the computer to function as the acquisition unit, the first calculation unit, the second calculation unit, and the condition determination unit.

[0016] Each aspect of the present invention may be implemented by a computer, in which case a control program for the information processing device that enables the computer to implement the information processing device by operating the computer as each part (software element) of the information processing device, and a computer-readable recording medium on which the program is recorded, also fall within the scope of the present invention. [Effects of the Invention]

[0017] According to one aspect of the present invention, the mounting conditions for the weight can be determined in a simple manner. [Brief explanation of the drawing]

Embodiment for Carrying out the Invention

[0019]

Embodiment 1

[0020] As shown in FIG. 1, the elevator system 100 includes an elevator car 1, a hoistway 2, a main rope 3 for raising and lowering the elevator car 1, a guide rail 4, a traveling cable 5, and a compensating rope 7.

[0021] The elevator car 1 is configured to carry people and goods and move up and down in the hoistway 2. The elevator car 1 is suspended by the main rope 3 and moves up and down inside the hoistway 2 by the delivery of the main rope 3 by a hoisting machine (not shown).

[0022] As shown by reference numeral 1001 in Figure 1, guide shoes 20 are installed at the left and right ends of the upper 11 and lower 12 of the elevator car 1, respectively. Hereafter, the guide shoe 20 installed on the -X side of the upper 11 of the elevator car 1 will be referred to as guide shoe 20A, the guide shoe 20 installed on the +X side of the upper 11 of the elevator car 1 will be referred to as guide shoe 20B, the guide shoe 20 installed on the -X side of the lower 12 of the elevator car 1 will be referred to as guide shoe 20C, and the guide shoe 20 installed on the +X side of the lower 12 of the elevator car 1 will be referred to as guide shoe 20D.

[0023] Guide shoe 20A has a first surface 21 and a second surface 22 that face each other in the front-rear direction (Y-axis direction), and a third surface 23 that connects the first surface 21 and the second surface 22 at the center side of the elevator car 1, and has an open outer shape. The first surface 21 is the surface on the depth side, and the second surface 22 is the surface on the front side. Guide shoe 20B has a shape that is symmetrical to guide shoe 20A. Guide shoes 20C and guide shoes 20D have the same shape as guide shoes 20A and guide shoes 20B, respectively.

[0024] Guide rail 4 is a rail that extends vertically in the elevator shaft 2. Guide rails 4 are provided on the left and right outer sides of the elevator car 1. Hereafter, the guide rail 4 provided on the left outer side of the elevator car 1 will be described as guide rail 4A, and the guide rail 4 provided on the right outer side of the elevator car 1 will be described as guide rail 4B. Guide rail 4A is provided such that at least a portion of it is positioned between the first surface 21 and the second surface 22 of the guide shoe 20A and the guide shoe 20C. Guide rail 4B is provided such that at least a portion of it is positioned between the first surface 21 and the second surface 22 of the guide shoe 20B and the guide shoe 20D.

[0025] The traveling cable 5 is a cable that supplies power to the elevator car 1 and communicates with a control device (not shown) installed inside the elevator car 1 and a repeater 50. Figure 3 is a schematic diagram showing the relationship between the traveling cable 5 and the elevator car 1. As shown in Figure 3, one end of the traveling cable 5 is connected to the lower part 12 of the elevator car 1, and the other end is connected to the elevator repeater 50. As shown in Figure 3, the length of the traveling cable 5 hanging from the elevator car 1 differs depending on the position of the elevator car 1. This changes the suspension load of the traveling cable 5 applied to the elevator car 1. Specifically, the lower the elevator car 1 is, the smaller the suspension load of the traveling cable 5 applied to the elevator car 1 becomes, and the higher the elevator car 1 is, the larger the suspension load of the traveling cable 5 applied to the elevator car 1 becomes.

[0026] The compensation rope 7 is a compensation rope that compensates for the change in weight of the main rope 3 as the elevator car 1 rises and falls. Figure 4 is a schematic diagram showing the relationship between the compensation rope 7 and the elevator car 1. As shown in Figure 4, one end of the compensation rope 7 is connected to the lower part 12 of the elevator car 1, and the other end is connected to the counterweight 9 via a sheave 8. As shown in Figure 4, the length of the compensation rope 7 hanging from the elevator car 1 differs depending on the position of the elevator car 1. This changes the suspension load of the compensation rope 7 applied to the elevator car 1. Specifically, the lower the elevator car 1 is, the smaller the suspension load of the compensation rope 7 applied to the elevator car 1 becomes, and the higher the elevator car 1 is, the larger the suspension load of the compensation rope 7 applied to the elevator car 1 becomes.

[0027] In the elevator system 100, the elevator car 1 is raised and lowered by sliding a guide shoe 20 installed on the elevator car 1 against a guide rail 4 that extends vertically in the hoistway 2. This allows the elevator car 1 to be raised and lowered without tilting significantly.

[0028] Figure 5 is a schematic diagram illustrating the inclination of the elevator car 1. The diagram indicated by reference numeral 5001 shows the elevator car 1 in a state where it is tilted backward, and the diagram indicated by reference numeral 5002 shows the elevator car 1 in a state where it is tilted forward. Each diagram in Figure 5 is a cross-section perpendicular to the left-right direction, and shows a cross-section cut by a cross-section including the guide shoe 20A, guide shoe 20C, and guide rail 4A.

[0029] As described above, the suspension loads of the traveling cable 5 and the compensating rope 7 applied to the elevator car 1 decrease as the elevator car 1 is lower. Therefore, when the elevator car 1 is at the lowest floor, the suspension load is small, and it is tilted in the depth direction, as shown in the figure of reference numeral 5001. Hereafter, this state will be referred to as the first state. In the first state, the guide rail 4A is in contact with the first surface 21 of the guide shoe 20A and the second surface 22 of the guide shoe 20C.

[0030] On the other hand, the suspension loads of the traveling cable 5 and the compensating rope 7 applied to the elevator car 1 increase as the elevator car 1 is higher. Therefore, when the elevator car 1 is on the top floor, the suspension load increases, and it tilts forward as shown in the figure of reference numeral 5002. Hereafter, this state will be referred to as the second state. In the second state, the guide rail 4A is in contact with the second surface 22 of the guide shoe 20A and the first surface 21 of the guide shoe 20C.

[0031] Furthermore, at a certain position as the elevator car 1 moves from the lowest floor to the highest floor, the center of gravity of the elevator car in the depth direction coincides with the position where the main rope suspends the elevator car, and at this position, the posture of the elevator car 1 transitions from the first state to the second state. Hereafter, the position at which the posture of the elevator car 1 transitions from the first state to the second state will be referred to as the transition position.

[0032] Here, by setting the transition position to the vertical midpoint in the elevator shaft 2, the maximum distance between the elevator car's center of gravity and the position where the main rope suspends the elevator car can be minimized, and the maximum force acting between the guide shoe 20 and the guide rail 4 can be minimized. This minimizes the maximum vibration and collision noise generated when the guide shoe 20 passes over the step in the guide rail 4. For this reason, a weight is attached to the lower part 12 of the elevator car 1 so that the transition position is the vertical midpoint in the elevator shaft 2. Conventionally, determining the appropriate conditions for attaching the weight, such as weight and installation position, required trial and error, which was time-consuming. Therefore, the adjustment method in this embodiment adjusts the weight balance of the elevator car 1 by attaching a weight to the lower part 12 of the elevator car 1, and is a simple method for determining the conditions for attaching the weight. The adjustment method in this embodiment will be described below.

[0033] The adjustment system 200 that performs the adjustment method in this embodiment will be described with reference to Figures 6 and 7. Figure 6 is a block diagram showing the main components of the adjustment system 200. As shown in Figure 6, the adjustment system 200 includes a distance sensor 201, a control panel 6, and an information processing device 210.

[0034] As shown in Figures 1, 2, and 5, the distance sensor 201 is installed on the upper part 11 of the elevator car 1. As shown in Figure 2, the distance sensor 201 is located on the rear side of the guide shoe 20A. The distance sensor 201 measures the distance between the guide rail 4A and the distance sensor 201. The distance sensor 201 outputs distance information, which is the result of measuring the distance between the guide rail 4A and the distance sensor 201 (hereinafter also referred to as the second distance), to the information processing device 210. Communication between the distance sensor 201 and the information processing device 210 may be performed by wireless communication or by wired communication.

[0035] The information processing device 210 determines the mounting conditions for the weight to be attached to the lower part 12 of the elevator car 1. The information processing device 210 includes a communication unit 211 for the information processing device 210 to communicate with other devices, an input unit 212 for receiving input operations to the information processing device 210, a display unit 213 for displaying various information, a storage unit 214 for storing various data and programs used by the information processing device 210, and a control unit 220.

[0036] The control unit 220 comprehensively controls the operation of each part of the information processing device 210. The control unit 220 is composed of, for example, a calculation processing unit such as a CPU (Central Processing Unit) or a dedicated processor. The control unit 220 includes a synchronization unit 221, a first calculation unit 222, a second calculation unit 223, and a condition determination unit 224.

[0037] The synchronization unit 221 synchronizes distance information acquired from the distance sensor 201 via the communication unit 211 with the position information of the elevator car 1 acquired from the control panel 6 via the communication unit 211 to generate information indicating the transition position when the attitude of the elevator car 1 transitions from a first state to a second state (hereinafter also referred to as transition position information). In other words, the synchronization unit 221 functions as an acquisition unit that acquires transition position information by synchronizing distance information acquired from the distance sensor 201 with the position information of the elevator car 1 acquired from the control panel 6. In one embodiment of the adjustment system of this disclosure, an external device other than the information processing device 210 may generate transition position information by synchronizing distance information acquired from the distance sensor 201 with the position information of the elevator car 1 acquired from the control panel 6, and the information processing device 210 may acquire the transition position information from the external device.

[0038] Figure 7 is an example of a graph generated by the synchronization unit 221 synchronizing distance information acquired from the distance sensor 201 with position information of the elevator car 1 acquired from the control panel 6. The graph shown in Figure 7 was created with the horizontal axis representing the distance from the lowest floor and the vertical axis representing the distance between the first surface 21 of the guide shoe 20A and the guide rail 4A. The distance between the first surface 21 of the guide shoe 20A and the guide rail 4A can be determined by subtracting the distance between the guide rail 4A and the distance sensor 201 (i.e., the second distance) and the width of the guide rail 4A in the Y-axis direction from the distance in the Y-axis direction between the first surface 21 of the guide shoe 20A and the distance sensor 201. As shown in Figure 7, when the elevator car 1 is moved from the lowest floor (one end) to the top floor (the other end) of the elevator shaft 2, the distance between the first surface 21 of the guide shoe 20A and the guide rail 4A changes along the way. The synchronization unit 221 detects the position where the distance between the first surface 21 of the guide shoe 20A and the guide rail 4A changes as the transition position. If it takes time for the elevator car 1 to transition from the first state to the second state, the synchronization unit 221 may detect an intermediate position between the position where the elevator car 1 is no longer in the first state and the position where the elevator car 1 is in the second state as the transition position.

[0039] The first calculation unit 222 calculates the distance (hereinafter also referred to as the first distance) between the transition position detected by the synchronization unit 221 and the intermediate position in the vertical direction of the elevator shaft 2. The intermediate position in the vertical direction of the elevator shaft 2 is stored in advance in the storage unit 214, and the first calculation unit 222 calculates the first distance by reading the information on the intermediate position in the vertical direction of the elevator shaft 2 from the storage unit 214.

[0040] The second calculation unit 223 calculates the magnitude of the load connected to the lower end of the elevator car 1 at the transition position. In other words, the second calculation unit 223 calculates the magnitude of the suspension load of the traveling cable 5 and the suspension load of the compensating rope 7 applied to the elevator car 1 at the transition position. Specifically, the second calculation unit 223 reads the weight per unit length of the traveling cable 5 and the compensating rope 7 from the memory unit 214 and calculates the magnitude of the suspension load of the traveling cable 5 and the suspension load of the compensating rope 7 at the transition position.

[0041] The condition determination unit 224 determines the mounting conditions for the weight to be attached to the lower part 12 of the elevator car 1 based on the first distance calculated by the first calculation unit 222, the magnitude of the load connected to the lower end of the elevator car 1 calculated by the second calculation unit 223, and the suspension position where the main rope 3 is connected to the elevator car 1 when viewed from above. Specifically, the condition determination unit 224 calculates the difference between the magnitude of the load connected to the lower end of the elevator car 1 at the transition position and the magnitude of the load connected to the lower end of the elevator car 1 at the intermediate position, and determines the mounting conditions. The "magnitude of the load connected to the lower end of the elevator car 1 at the intermediate position" is stored in advance in the storage unit 214. In addition, when determining the mounting conditions, the condition determination unit 224 also takes into account the mounting positions of the traveling cable 5 and compensating rope 7 at the lower part 12 of the elevator car 1. The "mounting positions of the traveling cable 5 and compensating rope 7 at the lower part 12 of the elevator car 1" are stored in advance in the storage unit 214. The conditions for attaching the weights include, for example, the position where the weights are attached and the weight of the weights. The condition determination unit 224 determines the conditions for attaching the weights so that the transition position is at the vertical midpoint in the elevator shaft 2. The conditions for attaching the weights determined by the condition determination unit 224 are displayed on the display unit 213. This allows the worker adjusting the weight balance of the elevator car 1 to attach the weights appropriately based on the conditions for attaching the weights displayed on the display unit 213.

[0042] Next, an example of the adjustment method in this embodiment will be described with reference to Figure 8. Figure 8 is a flowchart showing an example of the adjustment method in this embodiment.

[0043] In the adjustment method of this embodiment, first, the elevator car 1 is moved from the lowest floor to the highest floor of the elevator shaft 2, and the distance between the guide rail 4A and the distance sensor 201 is measured using the distance sensor 201 (step S1).

[0044] Next, the synchronization unit 221 synchronizes the distance information obtained from the distance sensor 201 with the position information of the elevator car 1 obtained from the control panel 6 to detect the transition position where the elevator car 1 transitioned from the first state to the second state (step S2, detection step).

[0045] Next, the first calculation unit 222 calculates a first distance between the transition position detected by the synchronization unit 221 and the intermediate position in the vertical direction of the elevator shaft 2 (step S3, first calculation step).

[0046] Next, the second calculation unit 223 calculates the magnitude of the suspension load of the traveling cable 5 connected to the lower end of the elevator car 1 and the suspension load of the compensating rope 7 at the transition position (step S4, second calculation step).

[0047] Finally, the condition determination unit 224 determines the mounting conditions for the weight to be attached to the lower part 12 of the elevator car 1, based on the first distance calculated by the first calculation unit 222, the magnitude of the load connected to the lower end of the elevator car 1 calculated by the second calculation unit 223, and the suspension position where the main rope 3 is connected to the elevator car 1 when viewed from above (step S5, condition determination step). Then, the worker attaches the weight based on the mounting conditions for the weight determined by the condition determination unit 224.

[0048] As described above, in the adjustment method of this embodiment, the mounting conditions for the weight are determined based on information obtained from measuring the distance between the guide rail 4A and the distance sensor 201 while moving the elevator car 1 from the lowest floor to the highest floor of the elevator shaft 2 using the distance sensor 201. With this configuration, the mounting conditions for the weight can be determined by raising the elevator car 1 from the lowest floor to the highest floor only once, and the mounting conditions for the weight can be determined solely by measurement using the distance sensor 201. Thus, the mounting conditions for the weight can be determined in a simple manner. In addition, in one aspect of the adjustment method of this disclosure, the distance between the guide rail 4A and the distance sensor 201 may be measured using the distance sensor 201 while moving the elevator car 1 from the highest floor to the lowest floor of the elevator shaft 2.

[0049] In one aspect of the adjustment method of this disclosure, the detection step may be terminated in the detection step S2 if it is detected that the posture of the elevator car 1 has changed. In other words, the ascent of the elevator car 1 and the measurement by the distance sensor 201 may be terminated if it is detected that the posture of the elevator car 1 has changed. This makes it possible to determine the weight attachment conditions without moving the elevator car 1 to the top floor.

[0050] In the adjustment method of this embodiment, the distance sensor 201 measures the second distance between the guide rail 4A and the distance sensor 201, and the position where the second distance changes is detected as the transition position. However, the adjustment method of this disclosure is not limited to this. In one aspect of the adjustment method of this disclosure, a tilt sensor may be installed on the elevator car 1, and the transition position may be detected based on the change in the tilt of the elevator car 1 measured by the tilt sensor. When the distance sensor 201 is used, it is easier to detect changes in the second distance, so the transition position can be detected more accurately.

[0051] In the adjustment method of the embodiment of this disclosure, the distance sensor 201 is installed only on the guide shoe 20A, but the adjustment method of this disclosure is not limited to this. In one aspect of the adjustment method of this disclosure, the distance sensor 201 may also be installed on the guide shoe 20B. Then, the mounting conditions for the weight may be determined based on the result of measuring the distance between the guide rail 4A and the distance sensor 201 using the distance sensor 201 installed on the guide shoe 20A, and the result of measuring the distance between the guide rail 4B and the distance sensor 201 using the distance sensor 201 installed on the guide shoe 20B. This makes it possible to determine the mounting conditions for the weight while taking into account the horizontal rotation of the elevator car 1.

[0052] Furthermore, in one aspect of the adjustment method of this disclosure, a distance sensor 201 may also be installed on the right side of the guide shoe 20A (i.e., on the X-axis side). The conditions for attaching the weight may then be determined based on the results of measuring the distance between the guide rail 4A and the distance sensor 201 using the distance sensor 201 installed on the rear side of the guide shoe 20A, and the results of measuring the distance between the guide rail 4A and the distance sensor 201 using the distance sensor 201 installed on the right side of the guide shoe 20A. This makes it possible to align the center of gravity of the elevator car 1 with the position where the main rope suspends the elevator car, in both the left-right and front-back directions.
