Problems solved by technology

Due to the high position of the counterweight bracket and poor welding working conditions, it is difficult to install the counterweight bracket; because the counterweight bracket is formed by welding and the working conditions during welding are poor, and the welding skills of the workers are uneven, resulting in guide rails The welding quality between the mounting plate and the bottom plate is difficult to guarantee, and the welding strength may not be enough
In addition, when the guide rail mounting plate is welded to the bottom plate, the metal surface coating will be damaged, making the counterweight bracket easy to rust, especially in a relatively dark and humid elevator shaft, which will easily reduce the strength of the counterweight bracket and cause fracture. The guide rail cannot be fixed, causing the elevator car to shake, and the safety of the elevator car is reduced
[0006] In summary, due to certain defects in the structure of the existing elevator control cabinet, elevator lower beam and counterweight support, the existing elevator car has defects such as difficult maintenance, low safety, low production efficiency and high cost

Embodiment 1

[0040] Example 1. A safety elevator car such as figure 1 As shown, the elevator car is provided with an elevator control cabinet 1, and the bottom of the elevator car is provided with an elevator lower beam 2, and the elevator car is connected with a counterweight mechanism; It is connected with the elevator car, the counterweight block is connected with the counterweight guide rail through the counterweight guide shoe, and the counterweight guide rail is fixed with the elevator shaft through the counterweight bracket 3.

[0041] The elevator control cabinet 1 includes a bottom box and a cabinet door. The bottom box includes a bottom plate 110, one side of the bottom plate 110 is bent forward to form a first plate 111, and the other side of the bottom plate 110 is first forward and then inward. Bending to form a second plate 112; the cabinet door includes a panel 120 positioned at the front side of the bottom box, one side of the panel 120 is bent backward to form a third pla...

Embodiment 2

[0063] Example 2. The difference from Embodiment 1 is the structure of the lower beam 2 of the elevator. The lower beam 2 of the elevator in Embodiment 2 includes a bottom beam 21, a safety gear mounting plate 22 and two straight beam connecting plates 23 are provided at both ends of the bottom beam 21, and the bottom beam 21 is screwed to the safety gear mounting plate 22, Bottom beam 21 is screwed with straight beam connecting plate 23.

[0064] The bottom beam 21 includes two symmetrically distributed side beams 211. The side beams 211 are a U-shaped structure with an opening horizontally outward and are made of galvanized plate. The first installation hole 202, the two ends of side beam 211 are all provided with straight beam connecting plate 23, and described straight beam connecting plate 23 is the bent plate of L shape, material galvanized plate, and the end of side beam 211 is all provided with The first inserting plate 203 inserted into the straight beam connecting ...
