Description

Technical Field

[0001] The utility model belongs to the technical field of elevator accessories and relates to an elevator car and an elevator counterweight structure. Background Art

[0002] The counterweight device is a component of the elevator traction system. It is arranged in the elevator shaft and connected to the car through the traction rope and the traction wheel. During the movement of the elevator, the counterweight device slides up and down along the counterweight guide rail through the counterweight guide shoe, thereby balancing the weight of the car. Application No. 201920604078.2 discloses an elevator counterweight frame, which includes an upper crossbeam, a lower crossbeam and a column arranged between the upper crossbeam and the lower crossbeam. The upper crossbeam, the lower crossbeam and the column together form a support frame. The upper crossbeam Both ends of the beam have upper notches that can avoid the counterweight guide rails, and both ends of the lower cross beam have lower notches that can avoid the counterweight guide rails. The columns located on the left and right sides of the support frame are recessed inward from the outer side of the support frame to form guide grooves that can slide with the counterweight guide rails. The corresponding upper notches, guide grooves and lower notches are connected in sequence to jointly form guide channels arranged in the upper and lower directions of the support frame. The elevator counterweight frame of the utility model can reduce the risk of derailment and improve the utilization rate of the shaft space.

[0003] The lower crossbeam and the vertical crossbeam of the above-mentioned counterweight frame are fixed by only a few sets of screws during assembly. As a result, the strength at the connection between the two crossbeams is low. When the internal counterweight blocks are loaded with a large number, the connection between the crossbeams needs to be strengthened separately, otherwise the supporting strength is insufficient and they are easy to fall off from each other.
