Description

  Embodiments described herein relate generally to an elevator and a sheave cover mounting method.

  The elevator raises and lowers the cage room by winding a rope connecting the cage room and the counterweight with a hoist.

  The hoisting machine includes a sheave that hangs a rope, a motor that rotates the sheave, a slip-off preventing member that restricts the rope from coming off the sheave, and a sheave cover that covers the sheave. The come-off prevention member also serves as a locking tool for the sheave cover to the motor in order to fasten the sheave cover and the motor.

  In the conventional elevator, the locking member is composed of a bar threaded at both ends and nuts that are detachably attached to both ends of the bar. Therefore, adjustment work for adjusting the interval between the nuts to the width of the sheave cover is necessary.

  This adjustment operation may require repeated operations of adjusting the interval between the nuts and removing the sheave cover.

  Further, the hoisting machine is often installed near the ceiling of the hoistway, and it is often difficult to install the hoisting machine in the hoistway. Therefore, this adjustment work is inefficient.

It is a side view of an elevator. It is an external appearance perspective view of a hoisting machine. It is a disassembled perspective view of a hoisting machine. It is a front view of a slip prevention member. It is a front view which shows the slip prevention member which concerns on an application example.

  Hereinafter, an embodiment of an elevator and a sheave cover mounting method will be described in detail with reference to the drawings.

  One embodiment of the elevator of the present embodiment is a cage room, a counterweight, a rope that lifts the cage room and the counterweight, a sheave that hangs the rope, a motor that rotates the sheave, a sheave cover that covers the sheave, A bar having threading at both ends and a first terminal member and a second terminal member that are fixed to the bar by providing an outer dimension equal to the thickness of the sheave cover, and restricting the rope from coming off the sheave A slip-off preventing member for fixing the sheave cover to the motor.

  FIG. 1 is a side view of an elevator 100 according to the present embodiment. As shown in FIG. 1, an elevator 100 includes a cage room 101 in which passengers are placed, a counterweight 103, a rope 106 that lifts the cage room 101 and the counterweight 103, a hoisting machine 102 that winds the rope 106, and a cage room. A hoistway 110 in which 101 moves up and down, a landing-side door 104, a step unit 105 installed below the landing-side door 104, and a control unit 107 that controls the operation of the elevator.

  The basket room 101 includes a basket room side door 101A and an engagement device 101B installed on the hoistway 110 side of the basket room side door 101A.

  The landing-side door 104 includes a protrusion 104A that engages with the engagement device 101B on the hoistway 110 side.

  The control unit 107 raises and lowers the basket room 101 to the designated destination floor. When the basket room 101 arrives at the destination floor, the engaging device 101B and the protrusion 104A are engaged. When the cage room side door 101A is opened and closed in this state, the landing side door 104 is driven and opened and closed.

  FIG. 2 is an external perspective view of the hoisting machine 102. FIG. 3 is an exploded perspective view of the hoisting machine 102. As shown in FIGS. 2 and 3, the hoisting machine 102 includes a sheave 203 around which the rope 106 is wound, a motor 201 that rotates the sheave 203, a sheave cover 202 that covers the sheave 203, and the rope 106 is detached from the sheave 203. And a locking member 301 for restricting this.

  The stopper member 301 includes a bar 301L having threading at both ends, and a first terminal member 301A and a second terminal member 301B fixed to the ends of the bar 301L excluding threading at both ends.

  The first end member 301A and the second end member 301B may be nuts, for example, and are fixed to the bar 301L by welding, an adhesive, or other locking tools.

  One end of the stopper member 301 is fitted into a bolt hole 201 </ b> A of the motor 201. The other end of the stopper member 301 is inserted into an insertion hole 202 </ b> A provided in the sheave cover 202 and fastened by a nut 302.

  The hoisting machine 102 has at least one slip prevention member 301 on each of the basket chamber 101 side and the counterweight 103 side.

  The sheave cover 202 has a thickness W1 of the sheave 203 in the rotation axis direction.

  FIG. 4 is a front view of the detachment prevention member 301. As shown in FIG. 4, the locking member 301 includes a bar 301 </ b> L having both ends threaded, and a first end member 301 </ b> A and a second end member fixed to the end of the bar 301 </ b> L excluding the threaded ends. 301B.

  The length of the interval including the thickness of the first end member 301A and the second end member 301B, that is, the outer dimension is equal to the thickness W1 of the sheave cover 202.

  Therefore, when attaching the sheave cover 202 and the come-off prevention member 301 to the motor 201, the work of adjusting the distance between the first terminal member 301A and the second terminal member 301B becomes unnecessary.

  FIG. 5 is a front view showing a detachment preventing member 301 according to the application example. As shown in FIG. 5, the locking member 301 includes a complementary nut 301 </ b> C that complements the distance between the first terminal member 301 </ b> A and the second terminal member 301 </ b> B.

  When the length of the interval including the thickness of the first terminal member 301A and the second terminal member 301B is less than the thickness W1 of the sheave cover 202, one or more complementary nuts 301C are removed from the stopper member 301. It can be used at the end of the motor 201 side.

  In this case, the length of the interval including the thicknesses of the complementary nut 301C, the first end member 301A, and the second end member 301B, that is, the outer dimension is equal to the thickness W1 of the sheave cover 202.

  Accordingly, it is possible to easily adjust the attachment interval of the detachment prevention member 301.

  As described above, the elevator according to the present embodiment rotates the cage chamber 101, the counterweight 103, the rope 106 that lifts the cage chamber 101 and the counterweight 103, the sheave 203 that hangs the rope 106, and the sheave 203. Motor 201, sheave cover 202 covering sheave 203, bar 301L having threading at both ends, and first end member that is fixed to bar 301L with outer dimensions of a length equal to the thickness W1 of sheave cover 202 301A and the 2nd termination | terminus member 301B are provided, The fall prevention member 301 which fixes the sheave cover 202 to the motor 201 while regulating that the rope 106 remove | deviates from the sheave 203 is provided.

  Therefore, there is an effect that the hoisting machine 102 can be easily attached when the elevator 100 is installed in a building.

  Although several embodiments have been described, these embodiments have been presented by way of example and are not intended to limit the scope of the invention. These embodiments can be implemented in various other forms, and various omissions, replacements, and changes can be made without departing from the spirit of the invention.
