In addition to meeting the basic structural requirements of the upper beam, an elevator car maintenance device also needs to be provided to fix the car during elevator maintenance to prevent accidental falls.

[0003] At present, most of the maintenance devices for the upper beam of machine-roomless elevators are exposed structures, basically with the maintenance device externally fixed on the upper beam or columns and protruding a lot. In some cases, for the convenience of operation, even the electrical switches of the maintenance device are exposed; although this structure is simple to operate, there are many potential safety hazards during use, and it is easy to cause accidental injuries or loss of functions of the maintenance device due to scratching. With the improvement of living standards, the demand for sightseeing elevators is also increasing day by day, and there are certain aesthetic requirements for each component of sightseeing elevators. The exposed structure not only occupies a large space but also affects the aesthetics and cannot meet the requirements. Summary of the Invention

A sliding guide shoe or a rolling guide shoe is installed on the machine-roomless elevator upper beam, and the sliding guide shoe or the rolling guide shoe is engaged with a guide rail fixedly installed in the elevator shaft to drive the elevator car frame to move up and down along the guide rail. A maintenance support is also connected to the back side of the guide rail. The machine-roomless elevator upper beam realizes the locking of the maintenance support through the plug-in fit between the control maintenance device cylindrical pin and the waist-shaped hole on the maintenance support.

[0006] In the above solution, the machine-roomless elevator upper beam is composed of an upper beam body, a switch, a maintenance device cylindrical pin, and a maintenance device bushing. The maintenance device bushing sleeved with the maintenance device cylindrical pin is fixed at both ends inside the upper beam body; a bolt is screwed on the maintenance device cylindrical pin, and the bolt slides along the U-shaped opening provided on the maintenance device bushing to limit the maintenance device cylindrical pin. When the maintenance device cylindrical pin is at the innermost locking position of the U-shaped opening, the maintenance device cylindrical pin is in a contracted state; when the bolt drives the maintenance device cylindrical pin to insert into the waist-shaped hole on the maintenance support, the maintenance device cylindrical pin is at the outermost locking position of the U-shaped opening.

[0007] In the above solution, a switch is also installed inside the upper beam body, and the switch meshes with the opening of the cylindrical pin of the maintenance device.

[0008] In the above solution, a switch viewing window is provided on the upper beam body.

[0009] In the above solution, a maintenance opening is provided on the upper beam body, and the maintenance opening is centered and aligned with the U-shaped opening provided on the sleeve of the maintenance device.

Detailed implementation manners

[0023] To make the above objects, features and advantages of the present invention more obvious and understandable, the following combines the appended Figures 1 - 8 drawings and specific implementation manners to further elaborate the present invention in detail.

[0024] As Figure 1 shown, the upper beam structure of a machine-roomless elevator with a maintenance device in this embodiment includes a machine-roomless elevator upper beam 1, which is located above the elevator car frame 6, and both ends are installed with sliding guide shoes 3 or rolling guide shoes 4 through the guide shoe fixing holes 7c of the upper beam body, and are connected to other components of the car frame 6 through the column fixing holes 7d of the upper beam body; then the sliding guide shoes 3 or rolling guide shoes 4 are meshed and installed with the guide rail 2, and it is ensured that the elevator car frame 6 can smoothly slide along the guide rail 2, and the maintenance bracket 5 is fixed on the back side of the guide rail 2.

[0025] As Figures 2 - 8 shown, the upper beam 1 is composed of an upper beam body 7, a reinforcing rib 8, a switch 9, a cylindrical pin 10 of the maintenance device, a pipe sleeve 11 of the maintenance device and a bolt 12. Among them, the reinforcing ribs 8 are symmetrically arranged at both ends of the lower side of the upper beam body 7, and the pipe sleeve 11 of the maintenance device is fixed on the inner sides of both ends of the upper beam body 7. One end of the cylindrical pin 10 of the maintenance device is inserted into the pipe sleeve 11 of the maintenance device, and the other end is used as a free end to cooperate with the maintenance bracket 5.

[0026] A maintenance opening 7a is opened on the upper beam body 7 of this embodiment, a U-shaped opening 11a is opened on the pipe sleeve 11 of the maintenance device, a screw hole 10b is provided on the cylindrical pin 10 of the maintenance device, and the bolt 12 is screwed into the screw hole 10b of the cylindrical pin of the maintenance device, and the maintenance opening 7a and the U-shaped opening 11a are centered and aligned to ensure that the bolt 12 can move along the U-shaped opening 11a.

[0027] The cylindrical pin 10 of the maintenance device is inserted inside the bushing 11 of the maintenance device, and then the bolt 12 passes through the U-shaped opening 11a of the bushing of the maintenance device and is tightened and fixed on the threaded hole 10b of the cylindrical pin of the maintenance device. The switch 9 is installed inside the upper beam body 7 and meshes with the opening 10a of the cylindrical pin of the maintenance device. The switch state can be observed and adjusted through the switch viewing window 7b of the upper beam body.

[0028] As Figure 1 shown, the upper beam mechanism is located at the upper part of the elevator car frame and is a part of the car frame structure; both ends are meshed and installed with the guide rail 2 through the fixed sliding guide shoe 3 or the rolling guide shoe 4 to ensure that the car frame 6 can move freely along the direction of the guide rail 3. When the elevator is running normally, the cylindrical pin 10 of the maintenance device is in a contracted state. At this time, the bolt 12 is at the locking position at the innermost end of the U-shaped opening 11a of the bushing of the maintenance device, and the end of the switch 9 is in a meshed state with the opening 10a of the cylindrical pin of the maintenance device. This state can be observed through the switch viewing window 7b of the upper beam. When the machine-roomless elevator needs to be maintained, first move the upper beam 1 of the car frame 6 to a position aligned with the maintenance bracket 5, and then move the bolt 12 along the U-shaped opening 11a of the bushing 11 of the maintenance device. The bolt 12 drives the cylindrical pin 10 of the maintenance device to rotate and move outwards, and finally inserts the cylindrical pin 10 of the maintenance device into the waist-shaped hole 5a of the maintenance bracket. At this time, continue to move the bolt 12 to the other end of the U-shaped opening 11a of the bushing 11 of the maintenance device to complete the locking; while moving the bolt 12 to drive the cylindrical pin 10 of the maintenance device to rotate and move along the U-shaped opening 11a of the bushing 11 of the maintenance device, as the cylindrical pin 10 of the maintenance device rotates, the switch 9 is triggered to act simultaneously, cutting off the safety circuit to prevent the car from moving. It is not until the bolt 12 is moved back to the initial position after the maintenance process ends that the switch 9 resets and the elevator can run normally.

[0029] The above is only the specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention can easily think of changes or substitutions, which should all be covered within the protection scope of the present invention. Therefore, the protection scope of the present invention should be subject to the protection scope of the claims.
