Problems solved by technology

Therefore, it is necessary to increase the rigidity at the installation position of the anti-vibration member of the car frame by increasing the plate thickness or welding a separately produced reinforcing member, so that there are problems in that the weight of the car frame increases, or the number of parts increases, leading to an increase in cost
In addition, since the protrusion forming jig is pressed in from the upper surface of the web portion toward the opening direction in a state where the deformation of the web portion and the flange portion in the thickness direction is restricted, the protruding protrusion is formed. Disadvantages mentioned above: A special stamping process is required, resulting in an increase in cost, and it is not easy to respond to design changes of vibration-proof members

Abstract

The invention provides an elevator car frame, which can restrain distortion of flange parts for a front beam and a rear beam on the upper side due to loading inside the car without increasing the plate thickness, lower the manufacturing cost, easily adapt to the design change of vibration part materials and achieve lightness. A cross beam (13) comprises a web part (14); a pair of flange parts (15) formed by bending towards the two ends of the web part (14) along the width direcction into a right angle; a second folding part (17) bending from the end of the web part (14) and formed in a way to be opposed to the web part (14). The ends of the cross beam (13) are inserted into the openings of the front beam and the rear beam (10). The second folding part (17) is configured on the position right below a vibration-proof rubber (3) in a way to be face to face to the web part (14) on the length direction of the front and rear beams (10) and orthogonal to the inner surface of a flange part (12).

Description

technical field [0001] The present invention relates to a car frame for supporting an elevator car. Background technique [0002] In conventional elevators, the car and the counterweight are suspended from main ropes for traction, and are arranged so as to be able to move up and down in the hoistway, and the counterweight has a weight balanced with the weight of the car. The car includes a car room and a car frame that supports the car room. Furthermore, the car chamber is supported by the car frame via the vibration-proof member arranged at the lower portion of the car bottom, and the load of the car chamber is concentrated on the place where the vibration-proof member is attached to the car frame. Therefore, it is necessary to increase the rigidity at the installation position of the anti-vibration member of the car frame by increasing the thickness of the plate or welding a separately produced reinforcing member, so that there is a problem that the weight of the car fram...
