Description Elevator overnight car fixing device

Technical field

The present invention relates to a self-propelled elevator in which a car and a drive device for raising and lowering a counterweight are mounted on a counterweight, and particularly, a worker can get on a car to perform maintenance and inspection work on the drive device. The present invention relates to an elevator fixing device for fixing a car to a counterweight during an elevator operation. Technology background

FIG. 16 is a perspective view of a conventional self-propelled solar cell proposed in, for example, Japanese Patent Application Laid-Open No. 9-112459. FIG. 17 is a schematic view of the elevator apparatus. In Figs. 16 and 17, a car 2 and a counterweight 3 are provided in the hoistway of Elebe overnight. The car 2 and the counterweight 3 are guided by a car-side guide rail 4 and a weight-side guide rail 5 having a T-shaped cross section, respectively, and move up and down in the hoistway.

On the counterweight 3, a driving device 7 for driving the rope 6 by winding the rope 6 is mounted. The counterweight 3 is further provided with a brake device 31 for holding the both sides of the brim projected from the outer periphery of the sheave of the drive device 7 by spring pressure and braking. A car side rope fixing member 10 for fixing the mouth 6 on the car 2 side and a weight side rope fixing member 11 for fixing the rope 6 on the balancing weight 3 side are provided at the upper part of the hoistway. .

An elevator control device 35 including a drive inversion of a drive device 7 mounted on the counterweight 3 is installed at a predetermined position below the hoistway.

Drive device mounted on the counterweight 3 Elevator cable 3 2 including the power line for driving, the brake driving line, the speed feedback encoder line for position detection, etc. It is erected.

The elevating bamboo puller 32 is installed between the control device 35 and the drive device 7 via a relay point 33 on the building side and a relay point 34 below the car 2. The car 2 is suspended on the rope 6 between the car side rope fixing member 10 and the return wheel 8. The car 2 is hung on a mouthpiece 6 with a rope 6 wound around a hanging wheel 9 pivotally supported on the side surface of the car.

A balancing weight 3 is hung on a rope 6 between the balancing weight side rope fixing member 11 and the return wheel 8. The counterweight 3 is hung on a rope 6 by winding a rope 6 around a sheave of a driving device 7.

When the driving device 7 provided in the counterweight 3 is driven, the sheave rotates, and the car 2 and the counterweight 3 move up and down in the hoistway 1. Then, when car 2 goes down, counterweight 3 goes up, and when car 2 goes up, counterweight 3 goes down.

In a so-called self-propelled elevator in which the elevator 7 having such a configuration, that is, the driving device 7 for raising and lowering the car 2 is mounted on the counterweight 3, the maintenance of the driving device 7 is performed. At this time, the worker gets on the car 2 and moves the car 2 to a position where the maintenance of the drive unit 7 can be performed, that is, the position where the car 2 and the counterweight 3 pass each other, and extends the hand from the car 2 to drive. Check device 7.

If it is necessary to perform maintenance work on the drive unit 7 from the car 2 as described above, a device that mechanically prevents unintended movement of the car 2 during work has conventionally been provided by a hoistway such as a guide rail. A car fixing device for fixing a car to an inner stationary portion has been proposed. FIG. 18 is a perspective view of a conventional car fixing device proposed in, for example, Japanese Patent Application Laid-Open No. 2000-203774.

In FIG. 18, an operating mechanism 50 having a lock rod 41 that moves forward and backward in the longitudinal direction and a bracket 42 that fixes the lock rod 41 at a predetermined position is provided on the upper part of the car 2. The lock bar 41 has an operation lever 43 projecting from the side surface. Remove the operation lever 4 3 from the operation lever insertion groove 4 2 b of the bracket 4 2, and move the lock rod 41 in the direction of the fixing mechanism 4 4. When the car 2 is inserted into the lock rod insertion hole 44 a of the fixing mechanism 44 provided in the car 2, the car 2 is mechanically fixed. After that, the operation lever 43 is inserted into the operation lever insertion groove 42a to prevent the fixing mechanism 44 and the lock rod 41 from being disengaged.

In the conventional elevator car fixing device having such a configuration, the car 2 is fixed to a hoistway stationary portion such as a guide rail, for example. As a result, rope 6 ages If the length of the drive unit 7 is increased due to the construction, the position of the drive unit 7 with respect to the car fixing position is lowered, which causes a problem in maintenance and inspection work, which is a problem.

The present invention has been made in order to solve the above-described problems, and has a structure in which a car fixing device is fixed by connecting a car and a counterweight, and is affected by the aging of the rope. It is an object of the present invention to provide an elevator car fixing device that can keep the position of the driving device relative to the car fixing position constant.
