Description

Rigid guide rail falling protector Technical Field The utility model relates to the technical field of safety protection of high-altitude operation, in particular to a rigid guide rail falling protector. Background At present, in high-altitude operation scenes such as building, electric power, bridge construction and the like, the rigid guide rail falling protector is an important device for guaranteeing the safety of operators. Conventional safety guards mainly employ a trigger-type mechanical locking structure, for example, a locking mechanism is triggered by centrifugal force or a brake pad driven by a spring is used to realize a safety function. However, the prior art has the defects of delayed response, poor braking stability, complex structure, high maintenance cost, limited applicability and the like, and part of the falling protector is triggered by centrifugal force, but in the low-speed falling or initial sliding stage, the braking lag can be caused by insufficient centrifugal force, the locking can not be performed in time, and potential safety hazards exist. Disclosure of utility model The utility model mainly aims to provide a rigid guide rail falling protector, which aims to enable the falling protector to respond quickly and stably and improve the falling protection effect. In order to achieve the above purpose, the utility model provides a rigid guide rail falling protector, which comprises a connecting frame and a pull arm, wherein the connecting frame is provided with a movable cavity in a penetrating way, the inner wall of the connecting frame is provided with a stabilizing wheel and a lower wheel towards the movable cavity, the stabilizing wheel is connected to one side of the movable cavity, and the lower wheel is positioned below the movable cavity; The upper wheel is connected between the pull arm and the connecting frame, the upper wheel is connected to the top of the movable cavity, the pull arm is eccentrically connected to the upper wheel, a locking structure is arranged on one side of the pull arm, and a locking hole is formed in the pull arm. In an embodiment of the application, the connecting frame includes at least two stabilizing frames, a rotating shaft is arranged between the two stabilizing frames, the upper wheel rotates and is connected to the rotating shaft, at least two stabilizing wheels and two lower wheels are arranged on each stabilizing frame, the two stabilizing wheels are connected to the same horizontal line of the stabilizing frame, and the two lower wheels are connected to the same horizontal line of the stabilizing frame. In an embodiment of the application, two ends of the bottom of the stabilizing frame are provided with protecting blocks, one end of each protecting block is connected with the lower wheel, and the other end of each protecting block is connected with the periphery of the stabilizing frame. In an embodiment of the present application, a bottom of one of the protection blocks is concavely provided with a relief portion toward an end surface of the other of the stabilizing frames, and a width of the relief portion gradually increases along a direction from the lower wheel to the stabilizing wheel.
