Description

The invention relates to lifting equipment, in particular to the construction of elevator cabs.

Known elevator car [1], moved by a lifting device on vertical guide rails, containing walls assembled from sheet metal parts, which, to increase rigidity, are at least partially flanged and form profiles, and some of these forming wall parts of the profile are elongated outside the cabin contour at least down to form vertical parts of the carrier frame. The vertical parts of the supporting frame and horizontal beams to support the cab floor form a cantilever frame made with the possibility of moving the cab along the rails.

The disadvantage of this cabin is the complexity of its installation in the elevator shaft, due to the fact that the installation requires disassembly, and then subsequent assembly of the cabin in the shaft. In addition, the transportation of such a cabin is carried out in assembled form with a low container filling factor, which also relates to its shortcomings. Replacing an old cab of this design without disassembling the shaft is difficult. The inability to install shock absorbing devices does not reduce the noise in the cab during its movement.

Also known is the compartment of the elevator car [2], containing side panels of the walls, floor and ceiling, motionlessly connected by coupling elements installed vertically outside the compartment on each side, lighting devices and ventilation means located in the upper part of the compartment. The side panels of the walls are installed with a gap one relative to the other with the formation of zones for installation work from the inside of the cab, and the coupling elements are made in the form of corner profiles, the means for connecting the wall panels to each other - in the form of belts made of profile material, curved along the inner contour of the compartment, mounted on the top and the bottom of the wall panels.

The design of the described compartment of the elevator car allows you to transport it to the installation site in disassembled form and use it when replacing the old car without disassembling the shaft. However, the drawback of this compartment of the elevator car is the increased complexity during installation, since the mounting of wall panels is carried out outside the car by an installer located inside it, which greatly complicates the installation of the car in the shaft, especially with small gaps between the car and the walls of the shaft. In addition, it is not possible to unify wall panels in the manufacture of compartments of various sizes. The disadvantages of this compartment of the elevator car also include the fact that the elements for connecting the panels to each other are an integral part of the frame, which does not allow installation to change the size from the suspension axis of the car to the front wall of the shaft.

The objective of the invention is to reduce the complexity of mounting the compartment of the elevator car and improve unification.

The objective of the invention is solved by the following set of features, according to which in a compartment of an elevator car containing wall panels, floor, ceiling and means for connecting wall panels to each other, means for attaching wall panels to the floor, lighting devices and ventilation means, coupling elements mounted vertically outside the compartment, wall panels consist of one or more modules, the means for connecting the modules to each other is made in the form of holes on the said modules and inserts, as well as bent elements on the said inserts, in addition, tyazhnye elements are arranged along the opposite side walls and connected top and bottom beams to form the frame, wherein between the lower beam and the floor cushioning elements mounted on the upper beam - load control device and the ceiling consists of one or several elements. In addition, the device for attaching modules of wall panels to the floor is made in the form of a bracket rigidly attached to them. In this case, the modules of wall panels and inserts can be oriented both vertically and horizontally.

The compartment the elevator car consists of a frame containing the upper beam 1 with a device for controlling the loading of the elevator in the form of a weighing device 2 and the lower beam 3. The beams 1 and 2 are interconnected by tie elements in the form of risers 4. The compartment contains a ceiling 5, floor 6, rigidly connected with floor 6, threshold 7, wall panels of modules 8 and vertical inserts 9. Portal 10 forms a compartment doorway frame. On the lower beam 3 there are shock-absorbing elements 11. Modules 8 are U-shaped plates of sheet material with flanging inward. In the flange, holes for riveted joints and rectangular holes for mechanical quick-connects are made. Between modules 8 there are also inserts 9 of a U-shape with a flanging out. The inserts 9 have bent elements 12. The holes on the modules 8, the inserts 9 with bent elements 12 on them are a means of connecting the modules 8 to each other. On the lower part of the modules 8, fastening elements to the floor are rigidly mounted in the form of elastic brackets 13. In the upper part of the modules 8 there are holes for fastening to the ceiling and holes for ventilation. The modules 8 on one side are rigidly connected to the inserts 9 by means of a rivet connection 14. The ceiling 5 is supported by longitudinal beams 15 and consists of three elements.

When installing the cab, the cab frame is first installed inside the shaft in the elevator guides from the top 1, bottom 3 beams and risers 4, and it is fixed motionless relative to the shaft. A weighing device 2 is pre-mounted on the upper beam 1. Damping elements 11 are mounted on the lower beam 3, floor 6 with a threshold 7 is placed on them. Then, the central module 8 is mounted on the floor 6, pre-connected to the inserts 9 by means of a rivet connection 14. Then, in series install the following modules 8 with pre-riveted on one side of the inserts 9. On the other hand, the modules 8 through the inserts 9 are connected to each other using bent elements 12. Connect the portal 10 from the side of the doorway. In the upper part of the modules 8, transverse beams 15 are mounted on which a ceiling 5 consisting of several elements is mounted. To increase rigidity, each module 8 is attached to floor 6 using a flexible bracket 13. All installation work is carried out from the inside of the cab.

In the described example of a specific embodiment of the elevator car compartment, the wall panel modules and inserts are oriented vertically. Possible execution of a compartment of the elevator car with horizontally oriented modules of wall panels and inserts. The principle of their connection is similar.

This design of the compartment of the elevator car allows you to reduce the complexity of its installation in the mine, excluding laborious and non-ergonomic operations, in addition, it is possible to supply the car in disassembled form, which allows you to use it when replacing an old car without disassembling the shaft. Installation of the walls of the compartment is carried out without the use of tools. Ceiling elements are folded inward for easy replacement of lighting devices. The modular construction of the walls and ceiling provides unification of the elevator car compartment. The inventive design of the compartment of the elevator car also provides increased comfort by reducing noise during movement, since shock absorbers are installed between the frame and the car compartment itself.
