Description

Adjusting device and adjusting method for lift car
Technical Field
The invention relates to an adjusting device and an adjusting method, in particular to an adjusting device and an adjusting method for a lift car.
Background
Elevators are an important component in modern buildings, and in high-rise buildings, elevators are equipment that must be installed. The elevator drives the lift car to move up and down through the driving device, and people and articles in the lift car are convenient to transport between floors. Generally, the movement direction of the car is perpendicular to the horizontal plane, and in order to ensure the operation safety and reduce the noise, the car door is normally opened and closed, and when the car is installed, the requirement on the verticality of the car is high. The car is installed in the car frame, and the staff can go on under strict installation flow during the installation, nevertheless because machining precision, assembly accuracy limit, the plumbing of car receive certain restriction, if improve the plumbing of car through improving the precision, then waste time and energy, and the cost is too high.

Preferably, the transverse screw and the longitudinal screw are further fixed with backing screws, and the backing screws are used for limiting the stroke of the adjusting nuts. The adjusting nut can only finely adjust the car, the correct position of the car mainly depends on the installation correctness, the back-stopping screw can limit the stroke of the adjusting nut, and the damage caused by the overlarge stress of the thread when the stroke of the adjusting nut is overlarge is avoided.
Preferably, the adjusting nut is positioned inside the two straight beams. Therefore, the length of the transverse screw and the length of the longitudinal screw can be shortened, the stroke of the adjusting nut can be shortened under the condition of the same verticality deviation, and the verticality of the lift car can be improved conveniently.
Preferably, the transverse screw and the longitudinal screw are carburized. After the transverse screw and the longitudinal screw are subjected to carburization treatment, the surface wear resistance is increased, and the service lives of the transverse screw and the longitudinal screw are prolonged.
An adjusting method of an adjusting device for a car, comprising the steps of:
firstly, measuring the verticality of a lift car and judging the adjusting direction;
secondly, loosening the locking nut to reserve a space for adjusting the nut;
thirdly, adjusting an adjusting nut until the verticality of the lift car meets the requirement;
fourthly, tightening the lock nut.
In the third step, as described above, if the verticality of the car deviates in the left-right direction according to the result of the measurement of the verticality in the first step, adjusting the adjusting nut on the transverse screw rod until the car is rightly placed in the left-right direction; if the verticality of the car deviates in the front-back direction, adjusting the adjusting nut on the longitudinal screw rod until the car is aligned in the front-back direction, so that the verticality of the car meets the requirement.
Preferably, the adjusting nut is finally tightened by a force measuring wrench when being adjusted in the third step. According to the above, no matter how the adjustment is carried out, the adjusting nut needs to be screwed finally to fix the car, the force of the thread of the adjusting nut can be limited by screwing the adjusting nut with the force measuring wrench, and the service life of the adjusting nut is prolonged.
The invention has the beneficial effects that: the car can be rightly arranged in the left-right direction by adjusting the adjusting nuts on the transverse screw rods, and the car can be rightly arranged in the front-back direction by adjusting the adjusting nuts on the longitudinal screw rods, so that the verticality of the car is improved.
