[0002] In the prior art, the two ends of the return rope pulley beam are fixed by ring beams on both sides of the elevator shaft. This fixing method has the following defects: (1) Since the ring beams are located on both sides of the elevator shaft, the return rope pulley beam fixed on the ring beam will span the entire elevator shaft, which not only increases the material cost, but also takes up too much shaft space and interferes with the elevator door machine, affecting the operation of the elevator. (2) In an elevator shaft without a ring beam, the installation of the return rope pulley beam requires pre-drilling a hole in the wall of the elevator shaft, which is not only difficult to construct but also has low construction efficiency.

Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts shall fall within the scope of protection of the present invention.

[0030] See also Figure 1-4 As shown, a mounting assembly for a return rope pulley beam is shown, which is arranged in an elevator shaft 100 and includes four connecting plates 1 respectively provided at the circumferential ends of the return rope pulley beam 101, and four mounting brackets 2 arranged at intervals around the circumference of the return rope pulley beam 101. The four mounting brackets 2 correspond to the four connecting plates 1 one by one. The connecting plates 1 are provided with two slide grooves 3 extending in the vertical direction. The two slide grooves 3 are parallel to each other. Two sliding rods 4 are connected to the mounting bracket 2. The two sliding rods 4 correspond to the two slide grooves 3 one by one, and the corresponding sliding rods 4 are slidably connected to the slide grooves 3. The return rope pulley beam 101 is movably arranged in the elevator shaft 100 through the sliding cooperation between the sliding rods 4 and the slide grooves 3. In this way, through the sliding cooperation between the sliding rods 4 and the slide grooves 3, the return rope pulley beam 101 can move up and down within the length range of the slide grooves 3, effectively preventing the mounting bracket 2 from deforming when the building sinks.

[0031] The slide bars 4 are slidably arranged along the length of the chute 3. Each slide bar 4 is equipped with a locking member 5 for locking the slide bar 4 relative to the chute 3. The locking member 5 is located on the side of the connecting plate 1 away from the mounting bracket 2. It comprises a locking plate 50 that fits over the slide bar 4 and a locking ring 51 that is threadedly connected to the slide bar 4 and secures the locking plate 50 to the connecting plate 1. In this embodiment, the slide bar 4 is a bolt, and the locking ring 51 is a nut. After adjusting the position of the bolt in the chute 3, the nut can be tightened to secure the bolt in that position. The locking plate 50 further enhances the locking effect.

[0032] The mounting frame 2 includes a first mounting plate 20 and a second mounting plate 21 that are perpendicular to each other, and a reinforcing plate 22 connected to the first mounting plate 20 and the second mounting plate 21 at both ends. The sliding rod 4 is connected to the first mounting plate 20, and the second mounting plate 21 is used to connect to the elevator shaft 100. The first mounting plate 20 and the corresponding connecting plate 1 are parallel to each other and perpendicular to the second mounting plate 21.

[0033] In this embodiment, the first mounting plate 20 is provided with two mutually parallel, downwardly inclined first adjustment slots 23. The two first adjustment slots 23 correspond one-to-one with the two chute slots 3, and the slide rod 4 passes through the corresponding first adjustment slots 23 and chute slots 3. The provision of the first adjustment slots 23 allows the return pulley beam 101 to move within the length range of the first adjustment slots 23, and the distance between the return pulley beam 101 and the elevator shaft 100 can be increased or decreased as needed, thereby improving the space utilization of the elevator shaft 100.

[0034] The mounting assembly further includes two limit brackets 6 disposed within the elevator shaft 100 and located above and below the return pulley beam 101, respectively. The two limit brackets 6 are used to respectively support the upper and lower sides of the return pulley beam 101. When adjusting the return pulley beam 101, the two limit brackets 6 can limit the installation position of the return pulley beam 101, preventing the return pulley beam 101 from being installed too high or too low.

[0035] In this embodiment, the limiting frame 6 includes a first limiting plate 60 and a second limiting plate 61, which are perpendicular to each other. The first limiting plate 60 is arranged horizontally, and the second limiting plate 61 is arranged vertically. The second limiting plate 61 is provided with at least two retaining plates 62, and a retaining groove is formed between the retaining plates 62 and the second limiting plate 61. The return rope pulley beam 101 is also connected to the elevator guide rail 102, and the side of the elevator guide rail 102 is embedded in the retaining groove. Since the elevator guide rail 102 is fixedly connected to the return rope pulley beam 101, the provision of the retaining plates 62 can effectively improve the installation strength of the elevator guide rail 102 and the return rope pulley beam 101.

[0036] The mounting assembly also includes two brackets 7, which correspond one-to-one to the two limit frames 6. The brackets 7 include a first support plate 70 and a second support plate 71 that are perpendicular to each other. The first support plate 70 is arranged in the vertical direction and is connected to the elevator shaft 100, and the second support plate 71 is arranged in the horizontal direction and is slidably connected to the first limit plate 60.

[0037] In this embodiment, two second adjustment slots 72 are provided on the second support plate 71, and two adjustment rods 63 are provided on the first limit plate 60. The two adjustment rods 63 correspond one-to-one with the two second adjustment slots 72, and the corresponding adjustment rods 63 are slidably connected to the second adjustment slots 72. The adjustment rods 63 and the second adjustment slots 72 cooperate to adjust the distance between the second support plate 71 and the first limit plate 60, and the distance between the return rope pulley beam 101 and the elevator shaft 100 is adjusted in conjunction with the first adjustment slot 23.
