[0022] To enable those skilled in the art to better understand the present invention, the technical solutions of the present invention 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 invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort should fall within the protection scope of the present invention.

[0023] It should be noted that, unless otherwise specified, the embodiments and features and technical solutions in the present invention can be combined with each other.

[0024] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0025] For an example, please refer to... Figures 1-4 A machine room-less passenger elevator machine beam includes a machine beam body 1, a traction machine mounting plate 101 installed on the top of the machine beam body 1, a detection structure 2 provided on the machine beam body 1, the detection structure 2 including a first connecting plate 201 located at the top of the machine beam body 1, a first connecting member provided between the first connecting plate 201 and the machine beam body 1, a third connecting plate 208 provided above the first connecting plate 201, a top plate 205 fixedly installed on the top of the third connecting plate 208, and a connection between the third connecting plate 208 and the first connecting plate 201. A second connecting component is provided. A side plate 210 is installed on the side of the first connecting plate 201. A contact switch 211 is installed on the side plate 210. The side plate 210 is welded to the side of the first connecting plate 201. The contact switch 211 and the side plate 210 are connected by bolts. With the detection structure 2 provided in this application, when the wire rope detaches from the traction sheave, the wire rope rests on the top plate 205 and pushes the top plate 205 downward. The top plate 205 triggers the contact switch 211 to realize an alarm, thereby reminding maintenance personnel to take appropriate safety measures in a timely manner.

[0026] Furthermore, a reinforcing block 206 is fixedly connected to the bottom of the top plate 205. The reinforcing block 206 is fixedly connected to the side of the third connecting plate 208. The third connecting plate 208, the reinforcing block 206 and the top plate 205 are welded together. The reinforcing block 206 can reinforce and support the connection between the top plate 205 and the third connecting plate 208.

[0027] Furthermore, the first connecting member includes a second connecting plate 203 located below the main body 1 of the machine beam. A plurality of first bolts 202 are interlaced between the second connecting plate 203 and the first connecting plate 201. Nuts are provided on the first bolts 202. The first connecting plate 201 can be installed on the top of the main body 1 of the machine beam by the cooperation of the second connecting plate 203, the nuts and the first bolts 202.

[0028] Furthermore, the second connector includes several second bolts 204 that are interlocked between the first connecting plate 201 and the third connecting plate 208. Nuts are also provided on the second bolts 204. The third connecting plate 208 and the first connecting plate 201 can be connected together by the cooperation of the second bolts 204 and the nuts.

[0029] Furthermore, a spring 209 is fitted on the outer surface of the second bolt 204. The spring 209 is located between the third connecting plate 208 and the first connecting plate 201. The spring 209 is used to provide an upward force to the third connecting plate 208 and the top plate 205, so that the top plate 205 will not descend and trigger the contact switch 211 under normal conditions. After unscrewing the nut on the second bolt 204, the third connecting plate 208 can be removed from the second bolt 204, and then the spring 209 can be removed from the second bolt 204 for replacement.

[0030] Furthermore, a baffle 207 is fixedly connected to the side of the first connecting plate 201. The baffle 207 is located below the top plate 205 and is welded to the side of the first connecting plate 201. The baffle 207 is used to limit the downward stroke of the top plate 205 to prevent the top plate 205 from falling too far and damaging the contact switch 211.

[0031] Furthermore, the contact switch 211 is connected to an alarm, so that the alarm can sound when the contact switch 211 is triggered.

[0032] Furthermore, a rope head plate 102 is fixedly connected to the side of the traction machine mounting plate 101. A first reinforcing plate 103 is connected between the rope head plate 102, the traction machine mounting plate 101, and the main body of the machine beam 1. The rope head plate 102 and the traction machine mounting plate 101 are integrally formed, and the traction machine mounting plate 101, the rope head plate 102, and the first reinforcing plate 103 are welded together.

[0033] Furthermore, a second reinforcing plate 104 is connected between the bottom of the traction machine mounting plate 101 and the main body of the support beam 1. The second reinforcing plate 104 and the first reinforcing plate 103 are located on both sides of the main body of the support beam 1, respectively. The second reinforcing plate 104 is welded together with the traction machine mounting plate 101 and the main body of the support beam 1, which can reinforce the traction machine mounting plate 101.

[0034] Furthermore, support beams 105 are provided at both ends of the main body 1 of the machine beam. An L-shaped connecting plate 106 is connected between the support beam 105 and the side of the main body 1 of the machine beam. The L-shaped connecting plate 106 is connected to the main body 1 of the machine beam and the support beam 105 by welding or bolting.

[0035] The traction machine mounting plate 101 is provided with mounting holes for mounting the traction machine. After the traction machine is installed on the top of the traction machine mounting plate 101, the wire ropes are located on both sides of the main body 1 of the machine beam, and the position of the top plate 205 corresponds to the position of the wire ropes. When the wire ropes detach, the wire ropes are placed on the top plate 205 and drive the top plate 205 to move downward. During the descent of the top plate 205, the contact switch 211 is triggered, which enables the alarm to sound.
