[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0027] Example 1: Please refer to Figure 1 and Figure 2A car frame upper beam structure includes two upper beam bodies 1 that are arranged opposite to each other and connected. Two anti-rope wheel assemblies 2 are detachably connected to the outer side of each upper beam body 1 at intervals. The anti-rope wheel assembly 2 is a modular structure. The top height of the anti-rope wheel assembly 2 is not higher than the top height of the upper beam body 1, and the bottom of the anti-rope wheel assembly 2 is located at a position higher than the bottom of the upper beam body 1. The positions of the anti-rope wheel assemblies 2 on the two upper beam bodies 1 correspond one-to-one.
[0028] Continue reading Figure 1 and Figure 2 The two anti-rope wheel assemblies 2 on each upper beam body 1 are located at the left and right ends of the upper beam body 1, respectively.
[0029] Continue reading Figure 1 and Figure 2 A wire rope cover 10 is installed between two anti-rope wheel assemblies 2 on the same upper beam body 1. The wire rope cover 10 covers the wire rope between the two anti-rope wheel assemblies 2 and plays a protective role.
[0030] Continue reading Figure 1 and Figure 2 The upper ends of two anti-cord pulley assemblies 2, located at different positions on the upper beam body 1, are connected to the guide shoe mounting plate 4. A shock absorber 5 is provided between the upper end of the anti-cord pulley assembly 2 and the guide shoe mounting plate 4. The shock absorber 5 is preferably a shock-absorbing rubber. Alternatively, a shock-absorbing spring or the like can also be used.
[0031] Continue reading Figure 1 and Figure 2 The ends of the two upper beam bodies 1 are connected by bolts with safety clamp connecting plates 7. Both ends of the upper beam body 1 are connected to safety clamp connecting plates 7, which are U-shaped and serve to connect the two upper beam bodies 1. A second reinforcing rib 8 is welded between the middle of the two upper beam bodies 1, reinforcing the connection. A first reinforcing rib 6 is welded between the bottom of the guide shoe mounting plate 4 and the outer side of the upper beam body 1. The upper beam body 1 is a U-shaped channel steel, and a third reinforcing rib 9 is welded to the middle of its outer U-shaped channel. The first reinforcing rib 6 and the third reinforcing rib 9 provide structural reinforcement.
[0032] This utility model provides a novel car frame upper beam structure, which consists of an upper beam body 1, a shock absorber 5, a safety clamp connecting plate 7, a reverse rope pulley assembly 2, and a wire rope guard 10.
[0033] The upper beam is welded together from the guide shoe mounting plate 4, the upper beam body 1, the second reinforcing rib 8, the third reinforcing rib 9, and the first reinforcing rib 6. The upper beam welded parts, shock absorbers 5, safety clamp connecting plate 7, and anti-cord pulley assembly 2 are connected as a whole by bolts. A shock absorber 5 is installed between the upper beam welded parts and the anti-cord pulley assembly 2, which effectively reduces vibration and noise during elevator operation. The anti-cord pulley assembly 2 is modularly designed and individually detachable, thus solving the problem of convenient installation and replacement. The four wheels are arranged separately, allowing the elevator to ascend to its maximum height, suitable for shafts with relatively low top floors. A wire rope cover 10 is connected to two anti-cord pulley assemblies 2, providing dust protection and safety, and also counteracting the tension of the wire ropes on both sides of the anti-cord pulley assembly 2. This effectively solves the problems of insufficient top floor height preventing normal elevator installation, excessive noise and vibration during elevator operation, and inconvenient installation and maintenance of the anti-cord pulley on the car top.

[0035] Example 2: This example is based on Example 1 with the following changes:
[0036] like Figure 3 As shown, the positions of the anti-rope wheel assemblies 2 on the two upper beam bodies 1 correspond one-to-one. The two anti-rope wheel assemblies 2 at the corresponding positions are connected by a connecting component. The connecting component includes an intermediate part 11 and two long shafts 3 that are detachably connected to both ends of the intermediate part 11. The long shafts 3 at both ends of the intermediate part 11 are respectively connected to the two anti-rope wheel assemblies 2.
[0037] The intermediate component 11 is a tubular structure. The ends of the two long shafts 3 are inserted into the two ends of the intermediate component 11 and fixed with bolts. After loosening the bolts, the anti-rope wheel assembly 2 together with the long shafts 3 can be disassembled.
[0038] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
