Description

Elevator auxiliary binding device

The present invention is an elevator auxiliary that is capable of quickly and easily loading cargo by stably fixing the elevator car when loading the cargo into the elevator car in the elevator device, and preventing the elevator car from sagging according to the load of the loaded cargo. It is about the binding device.

In general, in various types of high-rise buildings constructed for residential and business purposes, elevator devices are installed for smooth vertical movement of passengers looking for the corresponding building.

Such an elevator device is provided with an elevator car that moves passengers while moving along a hoistway formed in a vertical direction inside the building while a passenger is on board, a motor unit, a traction machine, ropes, pulleys, etc. It is configured to include a mechanical unit for moving to the corresponding floor according to the passenger's button operation, and an elevator control unit for controlling the mechanical unit according to the passenger's button operation so that the elevator car is operated to the corresponding floor.

That is, in the elevator device, the elevator car is raised and lowered by the traction of the rope according to the motor driving, and according to whether the motor is driven and stopped according to the control of the elevator control unit, will be stopped

In such an elevator device, the rope for pulling the elevator car is arbitrarily stretched or decreased according to a load change (load: passenger/cargo), and accordingly, a problem occurs that the stopping position of the elevator car cannot be accurately controlled.

That is, when the number of passengers riding in the elevator car increases or a large amount of cargo is loaded, the rope is stretched due to the tension of the rope supporting the elevator car. , a step difference occurs due to the mismatch between the chin of the platform and the chin in the car.

Accordingly, as the platform chin and the chin in the car do not match, there is a problem that the passengers cannot get on and off and load the cargo quickly and easily.

Recently, an auxiliary binding device has been proposed to solve the problem caused by the mismatch between the platform jaw and the position of the elevator car as described above;

In Korean Utility Model Application No. 20-2012-0011712 (Name: Elevator stop position fixing device/2012.12.12.), as known in the Gazette, the upper side of the elevator car has a brake lining that is selectively in close contact with the rail and a position fixing device including a brake coil for operating the brake lining, the elevator control unit checks the stop state of the elevator car by checking the speed command and the brake output, and when the stop state is confirmed, the brake lining is placed on the rail An elevator stop position fixing device is described, which is configured to perform control so that the position of the elevator car is fixed regardless of the load in the car by applying a signal for stopping the operation of the brake coil in close contact.

Korea Utility Model Application No. 20-2012-0011712 (2012.12.12.)

However, in the conventional elevator auxiliary binding device made as described above, the brake lining is driven through electrical energy to form friction friction while in close contact with the rail to fix the elevator car to the rail. , there was a problem in that the driving of the brake lining is stopped and released because it is in a fixed state according to the interruption of the power supply.

In addition, according to the instantaneous load generated when loading the cargo of a large load, there was a problem that the position of the elevator car is changed by the sliding of the brake lining on the rail.

Accordingly, there was a problem in that it was not possible to secure the stability of the cargo loading operation.

The present invention has been proposed to solve the problems of the prior art, and an object of the present invention is to stably fix the elevator car when loading the cargo in the elevator car in the elevator device, It can prevent the elevator car from sagging so that the cargo can be loaded quickly and easily; In particular, even when a safety accident such as a power outage occurs, the elevator car is stably fixed to the rail to provide an elevator auxiliary binding device that realizes stability in use.

Elevator auxiliary binding device according to the present invention for achieving the object of the present invention as described above, the rail installed while having a length vertically in the elevating space of a building; In an elevator apparatus comprising a; an elevator car having an accommodating space therein while being guided vertically on the rail; a binding body provided in and having a binding hole formed in a direction toward the elevator car; It is provided in the elevator car and is installed so as to be capable of linear reciprocating movement in the direction of the binding hole of the binding body, while penetrating a guide tube made of a 'pipe'-shaped 'pipe' fixed to the upper surface of the elevator car. Including a binding rod, and a movable member having a movable member configured to selectively linearly reciprocate the binding rod through the control of a control unit configured to control the power of the power supply unit; It is fixed to the ends of the cradles fixed while having a gap between the inner wall of the; It is characterized in that the rail is fixed to the center of the binding body.
