In the aforementioned point contact type passenger elevator car roof straight beam clamp assembly, preferably, the car roof fixing beam and the fixing bracket are provided with a transverse adjusting long hole at the matching position.
In the aforementioned point contact type passenger elevator car roof straight beam clamp assembly, preferably, the matching part of the car roof and the car roof fixing beam is provided with an adjusting long hole extending towards the car frame vertical beam direction.
This technical scheme utilizes the sedan-chair top fixed beam on current car top both sides to set up installation rubber pad, and the rubber pad configuration is connected through fixed bolster and sedan-chair top fixed beam in car top four corners position, makes rubber pad and fixed bolster integral type structure through vulcanization process, makes the rubber pad have the stability of high strength, avoids the atress defect that connections such as screw brought simultaneously. The rubber pad designs into the angle steel type, has two right-angle sides, is positioned in fixed bolster and sedan-chair top fixed beam respectively, along with the sedan-chair bottom compression bottom shock pad and guarantee the action orbit about the car. The working surface of the rubber pad is designed into a convex arc surface at the part matched with the car frame vertical beam, so that the contact surface between the rubber pad and the car frame vertical beam is finally reduced in a point contact mode, and the guide buckling type straight beam shock absorption effect is also realized.
Further, the car top fixing beam is provided with a transverse adjusting long hole, so that the fixing support is transversely provided with a position adjusting space along the car frame vertical beam, and the installation of the car frame vertical beams with different widths is met. And the top of the lift car is also provided with an adjusting long hole which is used for adjusting the position relation between the rubber pad and the vertical beam of the lift car frame within the processing error range of the lift car so as to realize gapless contact.
Compared with the prior art, the beneficial effects of the utility model are that: the rubber pad and the car frame vertical beam are in point contact, and the car is guided to move up and down when the damping pad is compressed at the bottom of the car, so that the contact area between the car frame vertical beam and the rubber pad is reduced, the comfort of the elevator is ensured, and the friction force and the friction noise are reduced; meanwhile, when the situation of front and rear passenger carrying and unbalanced loading of the car occurs, the rigidity and hardness of the rubber pad can completely meet the inclination of the car caused by unbalanced loading force; from the aspect of installation and maintenance, the point contact is favorable for seamless contact adjustment between the rubber pad and two right-angle surfaces of the car frame vertical beam, so that the rubber pad plays the greatest role.
