Description

Technical Field

[0001] This utility model relates to a split double-fold fireproof landing door device, and more particularly to a split double-fold fireproof landing door device for heavy-duty elevators. Background Technology

[0002] Elevators have become an indispensable means of transporting people and goods in people's daily lives. Center-split double-fold doors consist of four inner panels that open and close on both sides. The two panels on the same side are folded together by door arms. Compared to center-split doors, they have a higher cargo transport capacity and are therefore widely used in enterprises. However, with the increasing awareness of safety, the requirements for elevator safety performance are also becoming higher. Especially with the increasing number of electrical appliances, fires are becoming more frequent. Among various disasters, fire is one of the most frequent and widespread threats to public safety and social development. Existing center-split double-fold fireproof landing door devices, when applied to heavy-duty elevators, require a corresponding increase in the length of the upper and lower sills, necessitate multiple adjustments, and are relatively inconvenient to install.

Detailed Implementation

[0014] The present invention will be further described below with reference to the accompanying drawings and embodiments, but this should not be construed as limiting the present invention.

[0015] Example: A double-fold fireproof landing door device for a heavy-duty elevator, configured as follows... Figure 1-2 As shown, it includes a door panel assembly, a sill assembly disposed on the lower side of the door panel assembly, and an upper sill frame assembly disposed on the upper side of the door panel assembly. A left slow shutter door panel 1 and a right slow shutter door panel 2 are symmetrically arranged. A left fast shutter door panel 3 and a right fast shutter door panel 4 are provided between the left slow shutter door panel 1 and the right slow shutter door panel 2. Sealing mechanisms are provided at the ends of the left fast shutter door panel 3 and the right fast shutter door panel 4. Multiple sets of symmetrically arranged positioning components are provided on the upper side of the upper sill frame assembly. A locking component is provided on one side of the positioning component.

[0016] The positioning component includes an installation support 11 set on the upper sill gantry assembly and an embedded part 12 provided in the shaft. The end of the embedded part 12 is provided with a positioning block 13, and the installation support 11 is provided with a locking block 14 corresponding to the positioning block 13.

[0017] The locking block 14 is provided with a guide groove 15 corresponding to the positioning block 13, and an elastic buckle 16 is provided on one side of the guide groove 15.

[0018] The locking assembly includes an angle iron 5, which includes a horizontal plate 6 connected to the upper sill frame assembly and a vertical plate 7 for connecting to the shaft. The horizontal plate 6 and the vertical plate 7 are provided with multiple sets of mounting grooves 8 that are perpendicular to the connection between the horizontal plate 6 and the vertical plate 7. A pressure plate 9 is provided on one side of the mounting groove 8 of the vertical plate 7, and expansion bolts 10 are provided in the pressure plate 9 and the mounting groove 8.

[0019] The upper sill gantry assembly is provided with side mounting plates 17 at both ends.

[0020] The working principle of this application is an improvement on the existing double-fold fireproof landing door device for heavy-duty elevators, particularly the improvement of the installation structure of the upper sill gantry assembly. During installation, the upper sill gantry assembly is first lifted using hoisting equipment, and then positioned and initially locked using a positioning component, reducing the number of adjustments. After positioning, a locking component secures the assembly, ensuring high reliability. The positioning component uses a pre-embedded part 12 in the shaft, with a positioning block 13 at the end of the pre-embedded part 12. The mounting support 11 is first fixed to the upper sill gantry assembly with bolts. Positioning is achieved by the locking block on the mounting support 11 engaging with the positioning block 13. Furthermore, the positioning block 13 has a guide section at its front end, allowing it to be pressed into a guide groove 15 and secured by an elastic latch 16. Next, expansion bolts 10 are used to fix the angle iron 5 in the shaft. The pressure plate 9 increases the contact area, making installation more reliable.
