Embodiment 1

[0029] refer to Figure 1-5 , a limit device for an elevator car, comprising a base 1, a rope hole 15 is opened in the middle of the upper surface of the base 1, and a load-bearing base 2 is provided at the four corners of the upper surface of the base 1 close to the rope hole 15, and four load-bearing Two mutually parallel H-shaped steel beams 14 are fixed between the upper surfaces of the base 2, and the middle parts of the upper surfaces of the two H-shaped steel beams 14 are fixed with bearing holders 10 by bolts. The same hexagonal rod 11 is rotatably connected between them, and the outer wall of the hexagonal rod 11 is fixed with a rope reel 9. The end of the hexagonal rod 11 is sleeved with a limit plate 12, and the two sides of the limit plate 12 are close to the circumferential edge. Both are provided with equidistant staggered conical teeth 13, and the upper surface of the H-shaped steel beam 14 near the side of the limit plate 12 is fixed with a C-shaped steel slide...

Embodiment 2

[0039] refer to Figure 1-3 , a limit device for an elevator car. Compared with Embodiment 1, this embodiment also includes an annular retaining ring at both ends of the end of the two-way screw 3 close to the through hole 17 in the L-shaped clamp 16, and the annular The diameter of the retaining ring is greater than the diameter of the through hole 17 to ensure that the two-way screw 3 will not move left and right during the rotation.

Abstract

The invention belongs to the technical field of elevator cars and particularly relates to an elevator car limiting device. In order to solve the problem that a cable reel is fixed just through electronic control locating pins and cannot be adjusted flexibly during maintenance, the elevator car limiting device provided by the invention comprises a base. The middle of the upper surface of the base is provided with a cable hole. Load-bearing bases are arranged at the four corners, close to the cable hole, of the upper surface of the base. Two parallel H-type girders are fixed between the upper surfaces of the four load-bearing bases. Bearing clamping seats are fixed to the middle portions of the upper surfaces of the two H-type girders through bolts. When the cable reel needs to be fixed in the using process, two clamping devices fixed to T-shaped sliding blocks can be moved face to face just by rotating a bi-directional screw rod to rapidly clamp a limiting disk in the middle. Moreover,through cooperation of a hexagonal rod with the locking effect, the elevator car limiting device can prevent the cable reel for slipping under large gravity, and improves the maintenance safety.

Description

technical field [0001] The invention relates to the technical field of elevator cars, in particular to an elevator car limiting device. Background technique [0002] The elevator car is usually placed in a dedicated elevator car frame, and the elevator car is raised and lowered by lifting the elevator car frame. In order to prevent the vibration and noise generated by the elevator car frame from being transmitted to the elevator car, an elastic damping rubber pad is usually arranged between the car bottom of the elevator car and the elevator car frame. However, in the actual installation process of the elevator car, since the car bottom frame of the elevator car is often closer to the vertical beam of the elevator car frame than the car wall, if the installation is not careful, the car bottom frame of the elevator car will deviate from the Its correct installation position will lead to the direct rigid contact between the bottom frame of the elevator car and the vertical be...
