Description

Technical Field

[0001] This utility model relates to the field of construction engineering transportation, and more specifically, to an anti-collision device for construction elevator doors. Background Technology

[0002] With the continuous advancement of science and technology, the construction industry in my country has achieved sustained and rapid development. Its status as a pillar industry in the national economy has been continuously strengthened, and its driving effect on the national economy has become more significant. In recent years, the construction industry has faced fierce competition, with many products constantly being innovated and upgraded, and construction products have higher standards and requirements.

[0003] The anti-collision protection device for construction hoist doors is particularly important. Previously, during construction, especially during the vertical transportation of construction hoists, there was no awareness of protecting the protective doors, and the safety awareness was weak. During the vertical transportation, the material carts in the car would slide or slip, causing the protective doors to be deformed or damaged, making the protective doors unable to be opened and creating a significant safety hazard. Utility Model Content

Two fixed square frames are installed inside the protective door. One end of the fixed square frame is connected to the steel beam connector, and the other end of the steel beam connector is connected to the collision avoidance steel beam. Two supporting columns are installed on the bottom plate of the elevator car, and the upper opening of the supporting columns corresponds to the collision avoidance steel beam.

[0007] Preferably, the support column is made of square steel, and one side of the support column is provided with a square opening or a U-shaped opening, with the openings of the two support columns facing each other.

[0008] Preferably, a steel pad is installed at the bottom of the support column, and the steel pad is installed on the floor of the car.

[0009] Preferably, the fixing frame is made of 3mm thick 50mm×50mm square steel, and the fixing frame is welded to the protective door.

[0010] Preferably, the fixed frame and the steel beam connector are connected by hexagonal self-drilling screws, and the steel beam connector is welded to the anti-collision steel beam.

[0011] Preferably, the steel beam connector is made of flat steel.

[0012] Preferably, the steel beam connector has a thickness of 3mm, a width of 40mm, and a length of 250mm.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] This utility model has a simple structure, is easy to construct, lightweight, simple to operate, and highly safe. It can be used to effectively protect the elevator door during the vertical movement of construction hoists on construction sites, thereby improving safety during transportation.

[0021] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0022] As shown in the figure, this utility model discloses an anti-collision device for construction elevator doors, including an anti-collision steel beam 1, supporting columns 2, and steel beam connectors 3. Two fixed frames 5 are installed inside the protective door 4. One end of the fixed frame 5 is connected to the steel beam connector 3, and the other end of the steel beam connector 3 is connected to the anti-collision steel beam 1. Two supporting columns 2 are installed on the bottom plate 61 of the elevator car 6. The upper opening 21 of the supporting column 2 corresponds to the anti-collision steel beam 1.

[0023] When transportation is required, the protective door 4 rises, and at the same time, the protective door 4 drives the fixed frame 5 to move upward. The fixed frame 5 drives the steel beam connector 3 to move upward, and the steel beam connector 3 drives the anti-collision steel beam 1 to move upward. When the protective door 4 is in place, the transport trolley is pushed into the elevator car 6. At this time, the protective door 4 descends, and the protective door 4 drives the fixed frame 5, the steel beam connector 3 and the anti-collision beam 1 to move downward. When the protective door 4 is in place, both ends of the anti-collision beam 1 enter the opening 21 of the support column 2. The opening 21 of the support column 2 prevents the anti-collision beam 1 from moving, thus playing a limiting role.

[0024] The transport vehicle is protected from impact by the anti-collision beam 1, thus protecting the protective door 4.

[0025] In one embodiment of this utility model, the support column 2 is made of square steel, and a square opening or a U-shaped opening is provided on one side of the support column 2, with the openings 21 of the two support columns facing each other. The U-shaped opening facilitates the accommodation of the anti-collision beam 1.

[0026] In one embodiment of this utility model, a steel pad 7 is installed at the bottom of the support column 2, and the steel pad 7 is installed on the floor 61 of the car. The steel pad 7 is connected to the floor 61 by fasteners.

[0027] In one embodiment of this utility model, the fixing frame 5 is a 3mm thick 50mm×50mm square steel, and the fixing frame 5 is welded to the protective door 4.

[0028] In one embodiment of this utility model, the fixed frame 5 and the steel beam connector 3 are connected by hexagonal self-drilling screws, and the steel beam connector 3 is welded to the anti-collision steel beam 1.

[0029] In one embodiment of this utility model, the steel beam connector 3 is a flat steel.

[0030] In one embodiment of this utility model, the steel beam connector 3 has a thickness of 3mm, a width of 40mm, and a length of 250mm.

[0031] This invention prevents material trolleys from slipping or rolling and colliding with the safety doors of construction hoists during the vertical transportation process, thus preventing safety issues.

[0032] The preferred embodiments of this utility model have been described above. It should be understood that this utility model is not limited to the specific embodiments described above. Devices and structures not described in detail herein should be understood as being implemented in a conventional manner within the art. Any person skilled in the art can make many possible variations and modifications to the technical solutions of this utility model using the disclosed methods and techniques, or modify them into equivalent embodiments with equivalent changes, without departing from the scope of the technical solution of this utility model. This does not affect the substantive content of this utility model. Therefore, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of this utility model, without departing from the content of the technical solution of this utility model, still fall within the protection scope of the technical solution of this utility model.
