Embodiment 1 FIG.
FIG. 1 is a plan view of a hoistway shared by a bank to which a plurality of elevators belong. FIG. 1 illustrates a case where three elevators belong to a bank.

  The hoistway 1 is shared by the bank to which the elevator 2a, the elevator 2b, and the elevator 2c belong.

  The elevator 2a includes a car 3a, a counterweight 4a, a car guide rail 5a, and a counterweight guide rail 6a. The car 3 a, the counterweight 4 a, the car guide rail 5 a and the counterweight guide rail 6 a are arranged on the left side of the hoistway 1. Below each of the cage 3a and the counterweight 4a, a shock absorber (not shown) is provided.

  The elevator 2b includes a car 3b, a counterweight 4b, a car guide rail 5b, and a counterweight guide rail 6b. The car 3 b, the counterweight 4 b, the car guide rail 5 b and the counterweight guide rail 6 b are arranged in the central portion of the hoistway 1. Below each of the car 3b and the counterweight 4b, a shock absorber (not shown) is provided.

  The elevator 2c includes a car 3c, a counterweight 4c, a car guide rail 5c, and a counterweight guide rail 6c. The car 3 c, the counterweight 4 c, the car guide rail 5 c and the counterweight guide rail 6 c are arranged on the right side portion of the hoistway 1. Under each of the car 3c and the counterweight 4c, a shock absorber (not shown) is provided.

  Thus, the elevator 2a, the elevator 2b, and the elevator 2c use the common hoistway 1. That is, the car 3a, the car 3b, and the car 3c move up and down in the hoistway 1 that is the same space.

  For example, a landing door 7a, a landing door 7b, and a landing door 7c are provided at a landing on the lowest floor of a building. The landing door 7a is arranged corresponding to the elevator 2a. The landing door 7b is arranged corresponding to the elevator 2b. The landing door 7c is arranged corresponding to the elevator 2c.

  For example, a pit doorway 8a, a pit doorway 8b, and a pit doorway 8c leading to the inside of the hoistway 1 are provided at a landing on the lowest floor of the building. The pit entrance 8a is arranged near the landing door 7a corresponding to the elevator 2a. The pit entrance 8b is arranged near the landing door 7b corresponding to the elevator 2b. The pit entrance 8c is disposed in the vicinity of the landing door 7c corresponding to the elevator 2c. The pit entrance 8a, the pit entrance 8b, and the pit entrance 8c are used, for example, when maintenance personnel enter the pit and perform maintenance work.

  A self-propelled mobile body 9 is provided in the pit of the hoistway 1. The housing of the self-propelled moving body 9 can be moved on the floor surface of the pit by a moving mechanism. The moving mechanism has, for example, wheels and a motor. The housing of the self-propelled moving body 9 may include a member such as a roof for protecting from a falling object in the pit.

  A charger 10 is provided in the pit of the hoistway 1. The charger 10 is installed near the wall of a pit, for example. The charger 10 is connected to a power outlet (not shown), for example. For example, when the charging terminal of the self-propelled mobile body 9 comes into contact with the charging terminal of the charger 10, the secondary battery of the self-propelled mobile body 9 is charged.

  FIG. 2 is a functional block diagram of the falling object recovery system for an elevator pit in the first embodiment.

  In the building where the hoistway 1 is provided, an elevator control device 11 and a communication device 12 are provided. The communication device 12 is electrically connected to the elevator control device 11.

  For example, the elevator control device 11 may be a group management device that is provided for each bank and controls a plurality of elevators belonging to the bank. For example, the elevator control device 11 may be a device that is provided for each elevator and controls one elevator.

  The communication device 12 can communicate with the monitoring center 13 via a network, for example. The elevator control device 11 can communicate with the monitoring center 13 via the communication device 12.

  For example, the monitoring center 13 is provided in a building different from the building in which the hoistway 1 is provided. The monitoring center 13 is provided, for example, in an elevator management company. For example, the monitoring center 13 may be able to communicate with a plurality of communication devices 12 provided in different buildings. The monitoring center 13 includes a command unit 14.

  An elevator maintenance person carries the maintenance terminal 15, for example. The maintenance terminal 15 can communicate with the communication device 12. Communication between the maintenance terminal 15 and the communication device 12 may be wired communication or wireless communication.

  The self-propelled mobile body 9 includes a communication unit 16, a sensor 17, a recovery mechanism 18, and a control unit 19. The communication unit 16, the sensor 17, the recovery mechanism 18, and the control unit 19 are provided, for example, inside or on the surface of the self-propelled mobile body 9.

  The communication unit 16 has a wireless communication function. The communication unit 16 can perform wireless communication with the communication device 12, for example. For example, the communication unit 16 can indirectly perform wireless communication with the maintenance terminal 15 via the communication device 12. For example, the communication unit 16 can directly perform wireless communication with the maintenance terminal 15 without using the communication device 12.

  The sensor 17 detects an object existing around the casing of the self-propelled mobile body 9. As the sensor 17, for example, at least one kind such as an infrared sensor, an ultrasonic sensor, or a contact sensor is used.

  The recovery mechanism 18 is provided for recovering an object existing on the floor surface on which the casing of the self-propelled mobile body 9 moves. As the collection mechanism 18, for example, an electric blower and a dust collection chamber may be provided. As the recovery mechanism 18, for example, a magnet may be provided. As the collection mechanism 18, for example, a soil discharge plate for pushing and moving an object on the floor surface in the traveling direction of the housing may be provided.

  The control unit 19 moves the housing of the self-propelled moving body 9 by operating the moving mechanism. The control unit 19 performs a collecting operation using the collecting mechanism 18 while moving the casing. The collection operation may be performed in a state where the housing is temporarily stopped. The collection operation may be, for example, sucking an object into the dust collection chamber with an electric blower. The collection operation may be, for example, causing an object to be attracted to a magnet. The collection operation may be performed by, for example, pushing and moving an object on the floor surface with a soil removal board.

  For example, the control unit 19 controls the movement of the housing based on the detection result of the sensor 17. For example, when an obstacle such as a wall in a pit, a shock absorber, or a guide rail is detected by the sensor 17, the control unit 19 changes the traveling direction of the housing.

  Examples of the operation mode of the self-propelled mobile body 9 include a normal mode, a search mode, and a remote operation mode.

  When the self-propelled mobile body 9 is in the normal mode, the control unit 19 moves the housing based on information set in advance. In this case, the control unit 19 may move the housing at a preset date and time, for example. In this case, for example, the control unit 19 may move the housing at predetermined time intervals. In this case, the control unit 19 may move the casing uniformly with respect to the entire floor surface of the pit, for example, according to a preset movement route.

  When the self-propelled mobile body 9 is in the normal mode, the control unit 19 causes the housing to wait at a standby position in a preset pit, for example, after the operation of the housing set in advance is completed. The standby position in the normal mode may be set to a position where the self-propelled mobile body 9 is charged by the charger 10, for example. The standby position in the normal mode may be set to a position close to any of the pit entrance 8a, the pit entrance 8b, and the pit entrance 8c, for example.

  The command unit 14 of the monitoring center 13 transmits a search command to the self-propelled mobile body 9 via the communication device 12.

  For example, when the monitoring center 13 is informed that the user has dropped something into the pit through the gap between the car 3a of the elevator 2a and the landing threshold, the command unit 14 communicates with the building where the user has dropped the object. A search command is transmitted to the device 12. In this case, the search command includes information for identifying the elevator 2a that the user has lost. In this case, the communication device 12 transmits a search command to the self-propelled mobile body 9 in the pit of the bank to which the elevator 2a belongs.

  When the communication unit 16 receives the search command, the control unit 19 operates the self-propelled mobile body 9 in the search mode.

  When the self-propelled mobile body 9 is in the search mode, for example, the control unit 19 preferentially moves the casing on the landing door side range in the depth direction viewed from the landing side on the floor surface of the pit. The range may include, for example, a portion of the floor of the pit that is in front of the car shock absorber. The specific range may be set according to the arrangement of structures in the hoistway 1 and the width of the pits.

  When the self-propelled mobile body 9 is in the search mode, the control unit 19 moves the casing with priority given to the range corresponding to the elevator specified by the search command on the floor surface of the pit, for example. For example, when the elevator 2a is specified by the search command, the control unit 19 moves the casing within a range located below the car 3a and the landing door 7a.

  When the self-propelled mobile body 9 is in the search mode, the control unit 19, for example, moves the casing in the range corresponding to the adjacent elevator after the movement in the range corresponding to the elevator specified by the search command is completed. It may be moved. For example, when the elevator 2a is specified by the search command, the control unit 19 may move the casing in the range corresponding to the elevator 2b after the movement in the range corresponding to the elevator 2a is completed.

  When the self-propelled mobile body 9 is in the search mode, for example, after the operation of the housing based on the search command ends, the control unit 19 moves the housing at the standby position corresponding to the elevator specified by the search command. Wait. For example, when the elevator 2a is specified by the search command, the control unit 19 causes the casing to wait at a standby position close to the pit entrance 8a.

  For example, when cleaning the pit or collecting a fallen object, the maintenance staff may cause the maintenance terminal 15 brought into the pit to transmit a remote operation signal to the self-propelled mobile body 9 by wireless communication.

  When the communication unit 16 receives a remote operation signal from the maintenance terminal 15, the control unit 19 operates the self-propelled mobile body 9 in the remote operation mode. When the self-propelled mobile body 9 is in the remote operation mode, the control unit 19 moves the housing in accordance with the operation of the maintenance staff with respect to the maintenance terminal 15.

  FIG. 3 is a flowchart showing an operation example of the self-propelled moving body for the elevator pit in the first embodiment. FIG. 3 shows an example of the operation of the self-propelled moving body 9 in the search mode.

  In step S102, the self-propelled mobile body 9 starts operating in the search mode.

  In step S103, the self-propelled moving body 9 moves in a range in the pit corresponding to the elevator indicated by the search command.

  In step S104, the self-propelled moving body 9 moves in a range in the pit corresponding to another elevator adjacent to the elevator indicated by the search command.

  In step S105, the self-propelled moving body 9 stands by at a standby position in the pit corresponding to the elevator indicated by the search command.

  According to the first embodiment, the self-propelled moving body 9 moves on the floor surface of the pit of the hoistway 1 shared by the bank to which the plurality of elevators belong, and collects objects present on the floor surface. The maintenance staff only needs to collect the dust, garbage or fallen objects collected by the self-propelled mobile body 9. For this reason, the object in the pit of the hoistway 1 shared by the bank to which a some elevator belongs can be collect | recovered easily. As a result, the time required for cleaning the pit or collecting the falling object can be shortened.

  According to the first embodiment, when a search command is received from the monitoring center 13, the self-propelled moving body 9 moves preferentially in the range on the landing door side in the depth direction on the floor surface of the pit. For this reason, it is possible to preferentially search a range in which there is a high possibility that there is a fallen object in the pit.
