[0019] The following is combined with Figure 1-4 This application is described in further detail.

[0020] The present application embodiment discloses an elevator car top fixing structure. Figure 1-Figure 4, including a fixing member 1 and a fixing member 2, the fixing member 1 and the fixing member 2 are symmetrically arranged, and a connecting plate 8 is fixed to one end of the fixing member 1 and the fixing member 2 in an integral structure to form two symmetrical L-shaped structures for fixing the two ends of the car roof, and the outer walls of both sides of the fixing member 1 and the fixing member 2 are welded with a reinforcing plate 9, and the two sides of the fixing member 1 are symmetrically provided with an extension arm 3;

[0021] A fastening arm 4 is provided on the outside of the extension arm 3. The ends of the extension arm 3 and the fastening arm 4 that are away from each other are welded to the inner wall of the reinforcing plate 9. An adjustment groove 11 adapted to the extension arm 3 is opened inside the fastening arm 4. Therefore, the extension arm 3 can be movably adjusted in the adjustment groove 11 to adjust the extension distance. A number of fasteners 12 are evenly distributed on the inner side wall of the adjustment groove 11. The overall simple connection method is adopted, which reduces the difficulty of installation and maintenance and improves work efficiency. After adjustment, the extension arm 3 and the fastening arm 4 are connected by the fasteners 12.

[0022] Combination Figure 1-Figure 2 As shown, the surfaces of the extension arm 3 and the fastening arm 4 are provided with a plurality of fixing holes 6 at equal intervals, and the side wall of the extension arm 3 is provided with a mounting groove 10 adapted to the fastener 12, so as to facilitate further connection and fixation with the car roof by passing screws or bolts through the fixing holes 6, thereby increasing the connection area and improving the overall stability.

[0023] In addition, positioning ears 5 are welded to the outer walls of the extension arm 3 and the fastening arm 4, and the ends of the fixing parts 1 and 2 that are away from each other are fixed with connecting ears 7 in an integrated structure. A through hole is opened inside the connecting ear 7, and the external connecting parts can be connected through the connecting ear 7 for further reinforcement.

[0024] The implementation principle of the elevator car top fixing structure of the embodiment of the present application is as follows: when in use, the connecting plates 8 at one end of the fixing member 1 and the fixing member 2 are pre-installed at the corners on both sides of the car top. Since it is set in an L shape, one end of the connecting plate 8 can be attached to the outer wall of the car, and the fixing member 1 and the fixing member 2 are attached to the car top respectively, and then they are fixed to the car body by bolts respectively. During the installation process, the extension arm 3 and the fastening arm 4 are stretched, and one end of the extension arm 3 slides along the inner wall of the adjustment groove 11 to a suitable position, and then the fastener 12 passes through the installation groove 10 to fix it. The extension arm 3 and the fastening arm 4 are fixed to form a stable support, and then the positioning ear 5, the extension arm 3, and the fastening arm 4 are fixed to the car top through the fixing hole 6 by means of reinforcement structures such as bolts. By adding multiple fixing points, the overall fixing effect is greatly improved. The connection between the car top and the corners of the car side wall is formed by the connection setting of the fixing member 1 and the fixing member 2 2, which improves the overall strength and has better stability and reliability when bearing complex loads. Since the stability and reliability of the connection structure are improved, the elevator is safer during operation.
