Description
Technical Field
The invention relates to an elevator device, in particular to an elevator car door motor mounting structure and a mounting method and device thereof.
Background
The current installation structure of car door machine, as shown in fig. 1, when adopting the mode of installing on the car, generally adopt the wall-hanging, and the general practice on the market is that the screw hole for installation has been set up well in the front of access & exit upper plate, and the front of car door machine sets up the waist shape hole or the keyhole hole of equidistant with the screw hole on the access & exit upper plate, and the length direction in waist shape hole or keyhole hole is vertical direction, and the adjustment of direction about car door machine utilization waist shape hole or keyhole hole can be done.
During installation, two workers are generally required to support two sides of a car door machine, the back faces of a car and a door machine cross beam are attached to a support of an access upper plate, and the car door machine is hung on the support of the access upper plate through bolts. When the horizontal adjustment of the car door machine needs to be performed by at least two workers, the perpendicularity of the car door machine is adjusted by using the plumb line or the leveller of the car door machine is adjusted by using the gradienter, when one worker adjusts, the other worker is required to support the weight of the car door machine, and the installation is inconvenient. In addition, if car door machine and the sedan-chair door weight of hanging are when heavier, because car door machine crossbeam openly is waist shape hole, and waist shape hole length direction is vertical direction, under the action of gravity, only rely on the fastening frictional force of bolt, probably produce the risk that car door machine slided to the below, even the sliding of little distance all can lead to sedan-chair door scraping sill this moment, will produce the noise or cause the damage. And the lower part of the guide rail of the car door machine is not limited. When the car door decoration surface is impacted, the guide rail can deform, and the upper part of the car door is easy to separate from the door guide rail to cause danger.
Elevator installations generally include hoisting machines, hoisting ropes or belts, car frames, car floors, car rooms (car walls, car roofs, etc., and upholsteries), safety gears, counterweights, guide rails and rail supports, buffers, compensating devices, rope-reversing gear trains (guide wheels, car wheels, counterweight wheels), weighing devices, landing door machines and landing doors, door housings, sills, guide shoes, oil cups, end stop protection devices, leveling devices, safety contact plates, speed limiters, tension wheels, distribution boxes, control cabinets, consoles, landing calls, display components, and the like. When the elevator system operates, the elevator system is suspended on a traction sheave by using a traction rope or belt, the traction rope or belt is connected with a car and a counterweight, the traction of the car is realized by the friction force between the traction rope or belt and the front part of a traction sheave groove, and the counterweight is used for balancing the load of the car. The cage is driven by the hauling rope or belt to move vertically and smoothly along the guide rail laid in the elevator shaft. The lift car is a carrier of passengers or goods, and is composed of a lift car chamber, a lift car frame and a lift car bottom, wherein the lift car chamber is supported by a frame structure composed of the lift car frame and the lift car bottom, and guide shoes are arranged on the upper portion and the lower portion of the lift car frame and slide or roll on guide rails. The upper part of the guide shoe is provided with an oil cup for lubricating the guide rail. The traction system of the traction lift car comprises a traction machine, a pulley, a traction rope or belt, a compensation device and the like, wherein the traction machine is a main traditional device, the traction machine motor is driven to rotate by power supply of a distribution box, the control cabinet receives instructions sent by an operation box in the lift car and landing calls on the landing side, and the traction machine motor is controlled to pull the lift car and a counterweight to move up and down. The traction sheave is a rope sheave with a semicircular notch, friction force between the traction sheave and a steel wire rope drives the lift car and the counterweight to vertically move, and the diversion sheave forms a transmission mode with different traction ratios through a movable pulley (the lift car wheel and the counterweight wheel) and a fixed pulley (a guide pulley). The counterweight and the compensating device form a counterweight system, play a role in balancing the self weight and the load of the car and can greatly reduce the burden of the traction motor, and the compensating device is usually a compensating chain or a compensating cable which is suspended on the lower parts of the car chamber and the counterweight and is used for balancing the weight change caused by the continuous change of the length of a traction rope or belt on the counterweight side or the car side during operation. The overspeed governor, take-up pulley and safety tongs constitute mechanical speed limiting device, and the effect of overspeed governor is that the restriction elevator functioning speed exceeds the specified value, and when elevator functioning speed exceeded the specified value, the overspeed governor triggered the safety tongs and stopped the car. The tensioning wheel is used for tensioning the speed limiter to trigger the steel wire rope. The end station protection device is a safety protection travel switch before the car or the counterweight impacts the buffer and is arranged for preventing the elevator from exceeding the upper limit position and the lower limit position. The buffer is installed in the pit of elevartor shaft, is located the car and to heavy below, when the elevator moves from top to bottom, when taking place to surpass end station protection device because of some accident reason, will play the cushioning effect by the buffer, avoid the car or directly dash the top or hit the end to heavy. The leveling device is a sensor for generating a leveling signal of the elevator, and the leveling device sends out an arrival signal when the elevator arrives at each landing. The weighing device is a sensor for generating load weight feedback in the lift car, and transmits actual load information in the lift car to the control system in real time to be used as overload protection of the elevator. The safety touch panel or the light curtain monitors the passing condition of people or objects at the entrance and the exit of the elevator, and when people or objects pass through the safety touch panel or the light curtain, the elevator door is blocked to be closed, so that people and objects are prevented from being clamped by the elevator door. The control box in the cage, landing calling and display part constitute the control device of the elevator, which is the electric device for the driver or passenger to send control command to the elevator, and the display part indicates the arriving floor and the running direction of the cage.
