Description

Technical Field

[0001] The utility model relates to the technical field of construction elevator foot pedal components, and more specifically, to a construction elevator foot pedal mechanism. Background Art

[0002] The foot pedal for construction elevators is an auxiliary safety device used in construction elevators (construction elevators). Its main function is to increase the safety and comfort of workers. The foot pedal is usually made of materials such as steel plates, steel bars and concrete. The shape and size will vary according to different construction elevator models and specifications. Usually, the foot pedal will be connected to the construction elevator platform and can move up and down with the elevator. When the foot pedal is in use, it can be placed between the car and the construction floor to avoid gaps causing people to step on air and fall.

[0003] In the public literature, the utility model patent with patent publication number CN219408792U discloses a pedal device for construction elevators. This patent is mainly aimed at the gap between the elevator and the floor in traditional construction, which is usually reinforced with steel pipes on the floor, and the customized template above is used as a passage. This method needs to be set up outside each floor, which requires a lot of manpower and is costly. This patent mainly sets up a reinforcement component. When the walking pedal is moving, the support arm is inserted between each pair of positioning card plates, and the walking pedal is cantilevered by the support arm, so that the walking pedal has better stability and reliability when in use. However, it still has the following defects;

[0004] When the foot pedal is used on a construction elevator, the foot pedal can be placed in the designated position only after the pull rope is loosened. Once the pull rope is pulled and the foot pedal is not stored in the designated position, the upward movement of the construction elevator car will cause the foot pedal to collide with other construction layers. Therefore, it is difficult to accurately control the flipping position of the foot pedal. For this reason, it is necessary to provide a foot pedal mechanism for a construction elevator.
