Description

Technical Field

[0001] The utility model belongs to the technical field of door lock devices, and in particular relates to a door lock device used for a construction hoist. Background Art

[0002] Construction hoists, also known as construction elevators, are commonly used in construction to transport people and cargo. They are primarily used in high-rise and super-high-rise urban buildings. Their unique box structure provides a comfortable and safe ride for construction workers. They are often used in conjunction with tower cranes and are primarily used for interior and exterior decoration of high-rise buildings, as well as for the construction of bridges, chimneys, and other structures. A construction hoist consists of a car, drive mechanism, standard sections, wall attachments, chassis, railings, and electrical systems. There are many different types, categorized by operating mode: counterweight-free or counterweight-equipped. Construction hoists offer high load capacity, high speed, high efficiency, and safety, making them an indispensable piece of equipment in modern construction.

[0003] During the maintenance process, maintenance personnel discovered that due to the long-term lifting and lowering of the car, the initial position of the lock on it would change due to shaking, resulting in the problem of the lock hook not being properly engaged, which would cause the car to become unhooked during operation, posing a safety risk. Utility Model Content

[0004] In view of the problems raised by the above background technology, the purpose of the present utility model is to provide a door locking device for use in a construction elevator.

[0005] In order to achieve the above technical objectives, the technical solutions adopted by this utility model are as follows:

[0006] A door lock device used in a construction elevator comprises an elevator and a door mounted on the elevator, wherein the elevator is provided with a steady-state induction switch mounted on the side of the door, the door is provided with a hinged buckle, the hinged buckle is hingedly provided with a lock buckle, and the lock buckle is provided with an induction magnet.

[0007] It is further defined that the lock includes a lock handle, and the lock handle is integrally connected with a dial buckle, a plug buckle and a hook. With this design, the lock handle ensures the overall length specification and rigidity, the dial buckle is convenient for relevant personnel to dial, the plug buckle is placed between the two doors to achieve the function of dividing and strengthening the lock, and the hook achieves the purpose of the lock.

[0008] It is further defined that the lock is installed with an extension rod, and the induction magnet is installed at the end of the extension rod. Such a design is suitable for situations where the lock is far away from the steady-state induction switch, and the extension rod can make up for this distance.

[0009] It is further defined that the extension rod includes a base tube, the base tube is threadedly connected to a stud, the stud is integrally connected to a mounting column, and the induction magnet is installed on the mounting column. Such a design can adjust the length of the extension rod, thereby expanding the scope of use.

[0010] It is further defined that the hinge buckle and the steady-state sensing switch are both installed using waist-shaped holes and screws. This design can fine-tune the installation positions of the hinge buckle and the steady-state sensing switch to expand installation adaptability.

[0011] The beneficial effects of adopting the utility model are:

[0012] The structural design of the utility model can monitor the state of the lock when it is closed under the cooperation of the induction magnet and the steady-state induction switch. If the closure is not complete, the elevator will not be able to operate, thereby ensuring the safety of subsequent operation.

[0013] The utility model has reasonable structure, low manufacturing cost and good use effect. BRIEF DESCRIPTION OF THE DRAWINGS
