Summary of the Invention

Problems to be Solved by the Invention

[0004] In the conventional manual drive device for an elevator hoist, since the manual drive device and the handle are installed along the axial direction of the drive shaft, it is necessary to secure a space for turning the handle in the axial direction of the drive shaft. Depending on the installation situation of the elevator hoist, there has been a problem that it is difficult to secure the space necessary for manually rotating the drive shaft of the elevator hoist.

[0005] The present disclosure has been made to solve the above problems, and an object thereof is to provide an appliance mounting device for driving an elevator hoist that can secure a space for rotating the appliance mounting device for driving the elevator hoist.

[0009] Hereinafter, embodiments of the present disclosure will be described with reference to the drawings. Embodiment 1. FIG. 1 is a side view showing an elevator 100 to which a driving appliance mounting device 1 according to Embodiment 1 is applied. FIG. 2 is a top view showing a state in which the driving appliance mounting device 1 is installed in the elevator 100 of FIG. 1. FIG. 3 is a side view showing a state in which the driving appliance mounting device 1 is installed in the elevator 100 of FIG. 1. In FIG. 1, the car 101 is stopped at a stop position corresponding to the landing on the first floor, which is the lowest floor.

[0010] In the building where the elevator 100 is installed, a hoistway 130 of the elevator 100 is provided. Above the hoistway 130, a plurality of beam members 120 are installed along the horizontal direction. H-shaped steel materials are used for the beam members 120.

[0011] The elevator 100 includes a car 101 in which passengers can ride, a counterweight 103, a main rope 102, an elevator hoisting machine 104, a deflecting sheave 105, and an elevator control device (not shown).

[0012] The car 101 and the counterweight 103 are connected to each other by the main rope 102. One end of the main rope 102 is connected to the upper part of the car 101. The other end of the main rope 102 is connected to the upper part of the counterweight 103.

[0013] The elevator hoisting machine 104 and the deflecting sheave 105 are supported by a plurality of beam members 120. The elevator hoisting machine 104 includes a main body 110 including a motor, a drive shaft 111 protruding from the main body 110, and a drive sheave 112 fixed to the drive shaft 111.

[0014] The elevator hoisting machine 104 is arranged with the axis of the drive shaft 111 horizontal. The drive shaft 111 rotates about the axis of the drive shaft 111 by power supply to the motor. The drive sheave 112 rotates integrally with the drive shaft 111. A key groove 111a is formed on the surface of the drive shaft 111.

[0015] The main rope 102 is wound around the driving sheave 112 and the deflecting sheave 105. In the hoistway 130, the car 101 and the counterweight 103 are suspended by the main rope 102.

[0016] An elevator control device (not shown) controls the rotational operation of the driving sheave 112 by controlling the elevator hoisting machine 104. The main rope 102 wound around the driving sheave 112 moves as the driving sheave 112 rotates. As a result, the car 101 and the counterweight 103 can move vertically inside the hoistway 130.

[0017] The driving device mounting device 1 is a device mounted on the drive shaft 111 to rotate the drive shaft 111. The driving device mounting device 1 is fixed to the beam member 120 and connected to the drive shaft 111 as necessary. For example, the driving device mounting device 1 is used when power supply to the motor is not performed, such as during a power outage.

[0018] The driving device mounting device 1 includes a transmission mechanism portion 1a and a handle 5 which is a driving device. The transmission mechanism portion 1a has a force multiplying device 2, an interlocking mechanism 3, and a fixing member 4.

[0019] FIG. 4 is a cross-sectional view taken along line IV-IV of FIG. 3. FIG. 5 is a schematic view showing the attachment structure of the input shaft 21 and the handle 5 of FIG. 2.

[0020] The force multiplying device 2 has a force multiplying device housing 20, an input shaft 21 as an instrument connection portion, an output shaft 22, and a force multiplying mechanism 23 that amplifies the rotational force input from the input shaft 21 and outputs it to the output shaft 22.

[0021] The force multiplying device housing 20 has an internal space. The force multiplying device housing 20 is fixed to the beam member 120 by the fixing member 4.

[0022] The shape of the input shaft 21 is a rod shape. The input shaft 21 has an axis. A hexagonal hole 21a is formed in the end face of one end of the input shaft 21.

[0023] Here, an XYZ orthogonal coordinate system is used. In the XYZ orthogonal coordinate system, the coordinate axis along the axial direction of the drive shaft 111 is defined as the X-axis. Also, the coordinate axis that is orthogonal to the X-axis and along the vertical direction is defined as the Z-axis. Furthermore, the coordinate axis that is orthogonal to both the X-axis and the Z-axis is defined as the Y-axis.

[0024] The other end of the input shaft 21 is disposed inside the multiplier housing 20. The input shaft 21 is disposed along the Y-axis. Therefore, the axial direction of the input shaft 21 coincides with the direction along the Y-axis.

[0025] The shape of the output shaft 22 is a rod shape. One end of the output shaft 22 is disposed inside the multiplier housing 20. The output shaft 22 has an axis. The output shaft 22 is disposed along the Y-axis. Therefore, the axial direction of the output shaft 22 coincides with the direction along the X-axis.

[0026] Each of the input shaft 21 and the output shaft 22 is connected to a multiplier mechanism 23. The multiplier mechanism 23 includes a worm 23a, a worm gear 23b that meshes with the worm 23a, and an output gear 23c that meshes with the worm gear 23b.

[0027] The shape of the worm 23a is a rod shape. A tooth portion is formed on the outer peripheral surface of the worm 23a. The worm 23a has an axis. The input shaft 21 is integrally connected to an end of the worm 23a. The axis of the worm 23a is disposed along the Y-axis.

[0028] The axis of the worm 23a and the axis of the input shaft 21 are located on the same straight line. The worm 23a and the input shaft 21 are supported by the multiplier housing 20 so as to be rotatable about a straight line along the Y-axis.

[0029] The worm gear 23b has an axis. The worm gear 23b is rotatably supported by the multiplier housing 20 around the axis. The axis of the worm gear 23b is arranged along the Z axis.

[0030] The output gear 23c has an axis. The axis of the output gear 23c is arranged along the X axis. The output shaft 22 is integrally connected to the output gear 23c.

[0031] The axis of the output gear 23c and the axis of the output shaft 22 are located on the same straight line. The output gear 23c and the output shaft 22 are rotatably supported by the multiplier housing 20 around a straight line along the X axis.

[0032] The interlocking mechanism 3 includes a first gear 30 integrally attached to the output shaft 22, a second gear 31 as a drive shaft connection part, a chain 32 as a transmission member, and a key 33. The first gear 30 can rotate together with the output shaft 22 around the axis of the output shaft 22.

[0033] The second gear 31 is detachable from the drive shaft 111 of the elevator hoist 104. A key 33 is used for attaching the second gear 31 to the drive shaft 111.

[0034] FIG. 6 is an enlarged view of the second gear 31 in FIG. 3 as viewed from the VI direction. An insertion hole 31a is formed at the center of the second gear 31.

[0035] The drive shaft 111 is passed through the insertion hole 31a, and the key 33 is attached along a key groove 111a formed on the surface of the drive shaft 111.

[0036] Thereby, the second gear 31 is attached to the drive shaft 111. In a state where the second gear 31 is attached to the drive shaft 111, the second gear 31 and the drive shaft 111 rotate integrally around the axis of the drive shaft 111.

[0037] Returning to FIGS. 2 and 3, the description will be continued. The shape of the chain 32 is an endless shape. The chain 32 is wound around the first gear 30 and the second gear 31. In a state where the chain 32 is wound around the first gear 30 and the second gear 31, the chain 32 transmits a rotational force from one of the first gear 30 and the second gear 31 to the other.

[0038] The fixing member 4 is a gripping member such as a clip that can fix the multiplier device housing 20 to the beam member 120. However, as long as the fixing member 4 can fix the multiplier device housing 20 to a structure such as the beam member 120, a well-known mechanism can be used.

[0039] Returning to FIGS. 4 and 5, the description will be continued. The shape of the handle 5 is a T-shaped shape. The handle 5 has a horizontal member 50, a vertical member 51 protruding from the central portion in the longitudinal direction of the horizontal member 50, and a pair of gripping portions 52 protruding from both end portions of the horizontal member 50 in a direction opposite to that of the vertical member 51.

[0040] An attachment portion 51a is formed at the end of the vertical member 51. The shape of the attachment portion 51a is a bar shape with a hexagonal cross-section. The attachment portion 51a can be inserted into the hexagonal hole 21a. By inserting the attachment portion 51a into the hexagonal hole 21a, the handle 5 is attached to the multiplier device 2. That is, the handle 5 is detachable from the input shaft 21.

[0041] In a state where the attachment portion 51a is inserted into the hexagonal hole 21a, the axis of the vertical member 51 is arranged along the Y-axis. In a state where the attachment portion 51a is inserted into the hexagonal hole 21a, the handle 5 can rotate around the axis of the vertical member 51, that is, around a straight line along the Y-axis.

[0042] In a state where the second gear 31 is attached to the drive shaft 111 and the handle 5 is attached to the input shaft 21, when the handle 5 rotates around the axis of the input shaft 21, the rotational force of the handle 5 is transmitted to the drive shaft 111 via the transmission mechanism portion 1a.

[0043] As shown in FIGS. 2 and 3, the axial direction of the drive shaft 111 and the axial direction of the input shaft 21 are twisted with respect to each other. That is, in a state where the second gear 31 is attached to the drive shaft 111, the axial direction of the input shaft 21 is different from the axial direction of the drive shaft 111.

[0044] The handle 5 is attached to the force multiplying device 2 toward the axis of the drive shaft 111. That is, in a state where the second gear 31 is attached to the drive shaft 111 and the handle 5 is attached to the input shaft 21, the handle 5 is arranged on the side opposite to the axis of the drive shaft 111 as viewed from the transmission mechanism unit 1a.

[0045] The driving tool mounting device 1 is installed side by side with the elevator hoisting machine 104. That is, in a state where the second gear 31 is attached to the drive shaft 111, the axis of the output shaft 22 is parallel to the axis of the drive shaft 111.

[0046] The force multiplying device 2 is arranged so as to be side by side with the main body 110. That is, in a state where the second gear 31 is attached to the drive shaft 111, in the axial direction of the drive shaft 111, the input shaft 21 is located on the main body 110 side with respect to the second gear 31. In a state where the second gear 31 is attached to the drive shaft 111, in the axial direction of the drive shaft 111, the input shaft 21 is located within the range of the main body 110.

[0047] Next, a method of using the driving tool mounting device 1 will be described. The driving tool mounting device 1 is used when it is necessary to rotate the driving wire rope 112 without using the rotational force generated by the elevator hoisting machine 104 itself.

[0048] First, the force multiplying device housing 20 is fixed to the beam member 120 using the fixing member 4. Next, the second gear 31 is attached to the drive shaft 111. After passing the drive shaft 111 through the insertion hole 31a of the second gear 31, the key 33 is fitted along the key groove 111a to attach and fix the second gear 31 to the drive shaft 111.

[0049] A chain 32 is wound around a second gear 31 attached to a drive shaft 111 and a first gear 30. The attachment position of the second gear 31 and the fixing position of the power multiplying device housing 20 are adjusted as appropriate.

[0050] Next, the attachment portion 51a of the handle 5 is inserted into the hexagonal hole 21a. Thus, the installation of the driving tool attachment device 1 is completed.

[0051] In order to rotate the drive shaft 111 using the driving tool attachment device 1, the operator releases the brake of the elevator hoist 104 and applies a rotational force to the handle 5. The rotational force applied to the handle 5 is amplified by the power multiplying mechanism 23.

[0052] The amplified rotational force is output to the output shaft 22 and transmitted to the drive shaft 111 by the interlocking mechanism 3. The drive shaft 111 rotates by the rotational force transmitted from the second gear 31, and the drive sheave 112 rotates as the drive shaft 111 rotates.

[0053] In this way, the operator can rotate the drive sheave 112 by rotating the handle 5.

[0054] According to the driving device mounting apparatus 1 of the elevator hoisting machine 104 in the first embodiment, the transmission mechanism portion 1a having an input shaft 21 to which the handle 5 is detachable and a second gear 31 detachably attached to the drive shaft 111 protruding from the main body 110 of the elevator hoisting machine 104 is provided. Further, in a state where the second gear 31 is attached to the drive shaft 111 and the handle 5 is attached to the input shaft 21, when the handle 5 rotates about the axis of the input shaft 21, the rotational force of the handle 5 is transmitted to the drive shaft 111 via the transmission mechanism portion 1a. Also, in a state where the second gear 31 is attached to the drive shaft 111, the axial direction of the input shaft 21 is different from the axial direction of the drive shaft 111. Thereby, even if the handle 5 is attached to the input shaft 21, the handle 5 does not extend in the axial direction of the drive shaft 111. Therefore, even if the driving device mounting apparatus 1 is attached to the elevator hoisting machine 104, the handle 5 can be installed in a direction different from the axial direction of the drive shaft 111. Thus, a space for rotating the driving device mounting apparatus 1 can be secured.

[0055] According to the driving device mounting apparatus 1 of the elevator hoisting machine 104 in the first embodiment, in a state where the second gear 31 is attached to the drive shaft 111 and the handle 5 is attached to the input shaft 21, the handle 5 is disposed on the side opposite to the axis of the drive shaft 111 when viewed from the transmission mechanism portion 1a. Thereby, the handle 5 can be attached to the input shaft 21 facing the drive shaft 111. Therefore, even if the driving device mounting apparatus 1 is attached to the elevator hoisting machine 104, the handle 5 can be installed in a direction different from the axial direction of the drive shaft 111. Thus, a space for rotating the driving device mounting apparatus 1 can be secured.

[0056] According to the driving device mounting apparatus 1 of the elevator hoisting machine 104 of Embodiment 1, the transmission mechanism portion 1a has a force multiplying device 2 and an interlocking mechanism 3. Further, the force multiplying device 2 has a force multiplying mechanism 23, an input shaft 21 connected to the force multiplying mechanism 23, and an output shaft 22 connected to the force multiplying mechanism 23. Further, the interlocking mechanism 3 has a second gear 31. The force multiplying mechanism 23 amplifies the rotational force transmitted from the handle 5 to the input shaft 21 and transmits it to the output shaft 22. The interlocking mechanism 3 transmits the rotational force of the output shaft 22 to the drive shaft 111 by interlocking with the output shaft 22. Thereby, an operator can rotate the drive shaft 111 by turning the handle 5 with a small force. Therefore, the labor of the operator can be reduced.

[0057] According to the driving device mounting apparatus 1 of the elevator hoisting machine 104 of Embodiment 1, when the transmission mechanism portion 1a is attached to the drive shaft 111, the axis of the output shaft 22 is parallel to the axis of the drive shaft 111. Thereby, the force multiplying device 2 can be arranged while keeping a distance from the axis of the drive shaft 111 and alongside the drive shaft 111. Therefore, the force multiplying device 2 can be arranged at a position deviated from the axial direction of the drive shaft 111. Therefore, the handle 5 can be installed in a direction different from the axial direction of the drive shaft 111, that is, a direction different from the direction along the X axis. Thus, a space for rotating the driving device mounting apparatus 1 can be secured.

[0058] According to the driving device mounting apparatus 1 of the elevator hoisting machine 104 in the first embodiment, the interlocking mechanism 3 includes a first gear 30 attached to the output shaft 22 and a second gear 31 attached to the drive shaft 111. Further, the interlocking mechanism 3 further includes an endless chain 32 wound around the first gear 30 and the second gear 31 for transmitting the rotational force from one of the first gear 30 and the second gear 31 to the other. Thereby, the rotational force of the output shaft 22 can be transmitted to the drive shaft 111 having an axis existing on a straight line different from the straight line where the axis of the output shaft 22 exists. Therefore, the doubling device 2 can be arranged at a position deviated from the axial direction of the drive shaft 111, and the handle 5 can be installed in a direction different from the axial direction of the drive shaft 111. Thus, a space for rotating the driving device mounting apparatus 1 can be secured.

[0059] According to the driving device mounting apparatus 1 of the elevator hoisting machine 104 in the first embodiment, when the second gear 31 is attached to the drive shaft 111, in the axial direction of the drive shaft 111, the input shaft 21 is located closer to the main body 110 side than the second gear 31. Thereby, in the axial direction of the drive shaft 111, the handle 5 can be attached so as to be located closer to the main body 110 side than the second gear 31. Therefore, even when the handle 5 is attached, in the axial direction of the drive shaft 111, the space in the direction away from the main body 110 side from the second gear 31 is not occupied. Thus, a space for rotating the driving device mounting apparatus 1 can be secured.

[0060] Note that the driving device mounting apparatus 1 in the first embodiment has the handle 5. However, it is not limited thereto. The driving device mounting apparatus 1 may not have the handle 5. A tool that can be connected to the instrument connection portion may be prepared separately.

[0061] Also, the driving device mounting apparatus 1 in the first embodiment has the handle 5. However, it is not limited thereto. For example, an air-driven or electric-driven tool may be used. A tool that can be connected to the instrument connection portion can be appropriately used.

[0062] In addition, the driving tool mounting device 1 of Embodiment 1 has a T-shaped handle 5. However, it is not limited to this. The shape of the handle 5 may be appropriately selected.

[0063] Further, in the force multiplying mechanism 23 of Embodiment 1, a worm 23a and a worm gear 23b are used. However, it is not limited to this. As the force multiplying mechanism 23, for example, a well-known configuration combining a plurality of gears may be applied.

[0064] In addition, the driving tool mounting device 1 of Embodiment 1 has a force multiplying mechanism 23. However, it is not limited to this. A brake mechanism for preventing the rotation of the basket 101 in the falling direction may be incorporated into the driving tool mounting device 1. Further, a ratchet structure capable of setting the rotation direction of the input shaft 21 or the output shaft 22 may be incorporated.

[0065] Moreover, the transmission member of Embodiment 1 is a chain 32. However, it is not limited to this. A belt may be used as the transmission member. Further, a shaft member and a gear, which are well-known structures, may be used to transmit the rotational force of the output shaft 22 to the drive shaft 111.

[0066] In addition, an H-shaped steel material is used for the beam member 120 of Embodiment 1. However, it is not limited to this. Well-known steel materials such as I-shaped steel materials and C-shaped steel materials may be used for the beam member 120. The driving tool mounting device 1 is fixed to the beam member 120 corresponding to the shape of the beam member 120.

[0067] In addition, the driving tool mounting device 1 of Embodiment 1 is applied to the elevator 100 having the traversing carriage 105. However, it is not limited to this. The driving tool mounting device 1 can also be applied to an elevator 100 without the traversing carriage 105.
