Detailed Description
The present invention is described in terms of specific embodiments, and other advantages and benefits of the present invention will become apparent to those skilled in the art from the following disclosure. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.
As shown in fig. 1, the embodiment of the utility model provides a safe ladder stand, including ladder body 10, still including the safety belt device 20 who is used for protecting the operation personnel, safety belt device 20's both ends are provided with and connect rope 21, the tip of connecting rope 21 is provided with slider 22, seted up along the axial on the side pole of ladder body 10 both sides with slider 22 assorted spout 11, slider 22 slide set up in spout 11. The side bars of the ladder body 10 are also provided with an anti-slip mechanism 24 for stopping the rapid sliding down movement of the sliding block 22.
The embodiment of the utility model provides a there is safety belt device 20 through the cooperation slidable mounting of spout 11 and slider 22 on the side pole of ladder body 10, makes safety belt device 20 can together move upwards at the in-process of high altitude construction personnel climbing ladder body 10, in case take place the incident of falling, limited slip mechanism 24 can be used to in time stop the slider 22 of gliding fast on the pole of ladder body 10 side, avoids taking place the safety problem.
Specifically, the anti-slip mechanism 24 is provided with a plurality of anti-slip mechanisms 24, the plurality of anti-slip mechanisms 24 are equidistantly installed on the side bars of the ladder body 10, the anti-slip mechanism 24 includes two fan-shaped guide blocks 241 symmetrical about the central axis of the sliding chute 11, and a gap between the two fan-shaped guide blocks 241 forms a guide channel 242 which is narrow at the top and wide at the bottom and is used for the sliding of the sliding block 22.
As shown in fig. 2, the cross-section of the sliding block 22 is circular, and the upper surface of the sliding block 22 is further provided with a guide member 221 for passing through the guide channel 242, the guide member 221 is in a circular block shape and is vertically installed on the upper surface of the sliding block 22, and the end of the connection cord 21 is connected to the guide member 221 by a snap connection, which facilitates the release and replacement of the seatbelt apparatus 20.
In the present embodiment, the operation principle of the slip prevention mechanism is as follows:
in the process that the high-altitude operation personnel climb upwards, the safety belt device 20 is worn on the high-altitude operation personnel, the connecting rope 21 on the safety belt device 20 is slidably installed in the sliding groove 11 through the sliding block 22, and the sliding block 22 is driven to move upwards together along with the upward movement of the high-altitude operation personnel.
When the slide 22 passes through the anti-slip mechanism 24, the guide piece 221 on the slide 22 smoothly passes through the guide channel 242 by the guiding action of the fan-shaped guide plate 241; due to the design of the narrow top and wide bottom of the guiding channel 242, even if the slider 22 rotates a certain angle to make the guiding member 221 leave the initial vertical state, it can be returned to and pass through the anti-slip mechanism 24 in time under the guiding action of the guiding channel 242.
When the high-altitude operation personnel accidentally slide down, the safety belt device 20 drives the sliding block 22 to rapidly fall down, the sliding block 22 is driven to rotate by a certain angle due to unstable gravity center when the personnel fall down, the guide piece 221 is separated from the original vertical state, and the upper end of the guide channel 242 is narrow and only allows the guide piece 221 to vertically pass through, so that the sliding block 22 can be clamped and stopped in a certain anti-slip mechanism 24 and cannot further slide down, and the personal safety of the high-altitude operation personnel is ensured.
Here, in order to allow the slider 22 to rotate at a certain angle when dropping from one anti-slip mechanism 24 to another anti-slip mechanism 24, the vertical distance between two adjacent anti-slip mechanisms 24 is greater than the diameter of the slider 22.
Finally, when the high-altitude worker finishes the work and goes down, the round hole in the middle of the guide part 221 can be grasped by two hands, on one hand, the guide part 221 serves as a handrail for the worker to go down, and on the other hand, the guide part 221 can be ensured to not deviate by two hands and can smoothly pass through a plurality of anti-slip mechanisms 24.
Although the invention has been described in detail with respect to the general description and the specific embodiments, it will be apparent to those skilled in the art that modifications and improvements can be made based on the invention. Therefore, such modifications and improvements are intended to be within the scope of the invention as claimed.
