[0003] However, the lower beam of the existing machine-room-less elevator (that is, the lower beam of the car frame mentioned above) is mostly a straight beam structure, which is in four-point contact with the bottom of the car, and the contact surface is small, and the lower beam of this structure will cause The vertical beam of the car frame is installed at a position deviated from the center of gravity of the car (the lower beam is not at the center of gravity of the car), that is, the connecting line between the centers of the two vertical beams of the car frame and the center of gravity of the car are not on the same straight line, which will cause the elevator to fail in safety. When the clamp moves, the car produces a large overturning moment on the car guide rail, which increases the safety hazard of the elevator

Embodiment Construction
[0012] figure 1 It shows a specific embodiment of the lower beam structure of the machine room-less elevator of the present invention, which includes a horizontally arranged lower beam body 4, and two safety gear seats 7, two guide shoes 6 and two car floors are arranged on the lower beam body The rope wheel 3 and the safety gear seat 6 are provided with a safety gear 2 . One of the guide shoes 6 is arranged on the right side of one end of the lower beam body 4 , and the other guide shoe 6 is arranged on the left side of the other end of the lower beam body 4 . A horizontal slanting beam 1 is welded horizontally on the left and right sides of the lower beam body 4. The top surfaces of these two slanting beams 1 are flush with the top surface of the lower beam body 4, and the inclined beam 1 and the lower beam body 4 Arranged at a certain angle.
[0013] refer to figure 2 As shown, in a specific application, the lower beam structure is arranged at the bottom of the elevator...

The invention discloses a lower beam structure for an elevator without a machine room. The structure comprises a horizontally arranged lower beam and two safety gear blocks, two guide shoes and two car-bottom rope wheels which are arranged on the lower beam. Safety gears are arranged on the safety gear blocks, one of the guide shoes is arranged on the right side of one end of the lower beam, and the other guide shoe is arranged on the left side of the other end of the lower beam. Inclined beams with the tops leveled with the top of the lower beam is arranged at the tops on the left side and the right side of the lower beam respectively, and the inclined beams and the lower beam form a certain angle. The lower beam structure is high in strength and capable of enhancing the stability of an elevator car during operation.
Description
technical field [0001] The invention relates to the technical field of elevator equipment, in particular to a lower beam structure of a machine room-less elevator. Background technique [0002] The elevator car frame of the present machine room-less elevator generally consists of a car frame lower beam and two car frame vertical beams, wherein the car frame lower beam is horizontally arranged at the bottom of the elevator car, and the bottom ends of the two car frame vertical beams are respectively It is fixedly connected to both ends of the lower beam of the car frame. [0003] However, the lower beam of the existing machine-room-less elevator (that is, the lower beam of the car frame mentioned above) is mostly a straight beam structure, which is in four-point contact with the bottom of the car, and the contact surface is small, and the lower beam of this structure will cause The vertical beam of the car frame is installed at a position deviated from the center of gravity ...
