[0002] An attached lifting scaffold refers to a scaffold that is erected to a certain height and attached to a building structure through an attached support device, and relies on its own lifting mechanism to lift layer by layer with the building structure, and has functions such as safety protection, anti-overturning, anti-falling, and synchronous control. The attached lifting scaffold is also called a climbing formwork, and its most important safety protection device is an anti-falling device. The anti-falling device is always in a working state during the lifting and lowering process of the climbing formwork. In the climbing formwork industry, anti-falling devices are divided into two types: pendulum needle anti-falling devices and runner anti-falling devices, with pendulum needle anti-falling devices being the majority. During the lifting and lowering process of the climbing formwork, the anti-falling device needs to trigger the anti-falling device during the falling process to achieve the anti-falling function. If it cannot be triggered well, the anti-falling function will fail, resulting in major safety hazards. Summary of the Utility Model

[0031] The present utility model provides a multi-condition pendulum needle anti-falling structure.
[0032] In an embodiment of the present utility model, as Figures 1 to 8 shown, this multi-condition pendulum needle anti-falling structure is applied to a climbing frame. The climbing frame has a guide rail 500 and an attached wall support 400 connected to the guide rail 500. The guide rail 500 has a plurality of anti-falling stop rods 510 arranged at intervals. This multi-condition pendulum needle anti-falling structure includes:
[0033] A pendulum needle anti-falling device 100, which is rotatably installed on the attached wall support 400. The pendulum needle anti-falling device 100 includes an anti-falling body 110, a trigger end 140 and an anti-falling end 130 that protrude from the anti-falling body 110 and are arranged at an angle, and a first hanging portion 120 located at the edge of the anti-falling body 110. The anti-falling end 130 can abut against the anti-falling stop rod 510;
[0034] A reset elastic member 200, one end of the reset elastic member 200 is connected to the attached wall support 400, and the other end is connected to the first hanging portion 120. Among them, when the reset elastic member 200 is connected to the first hanging portion 120, the reset elastic member 200 is in a deformed state and drives the anti-falling end 130 to reset.
[0035] Specifically, both ends of the reset elastic member 200 are detachably hung on the wall-attached support 400 and the first hanging portion 120. At this time, the reset elastic member 200 is in a deformed state under tension, and the entire device is in a working condition of only ascending and not descending. When the guide rail 500 moves upward, the upward movement of the guide rail 500 drives the pendulum needle anti-falling device 100 to rotate. When the anti-falling end 130 passes through the anti-falling stop rod 510 on the guide rail 500, the anti-falling end 130 is reset under the pulling-back action of the reset elastic member 200; because the pendulum needle anti-falling device 100 is always in an anti-falling state under the action of the reset elastic member 200, it cannot descend. When the guide rail 500 falls, the device is in an anti-falling working condition, and the anti-falling end 130 directly hooks the anti-falling stop rod 510 of the guide rail 500 to achieve anti-falling, which can effectively achieve anti-falling, and is safe and reliable.
[0036] In some embodiments, the edge of the anti-falling body 110 further has a second hanging portion 150. When the reset elastic member 200 is connected to the second hanging portion 150, the reset elastic member 200 drives the trigger end 140 to reset. Specifically, when the guide rail 500 moves upward normally, the upward movement of the guide rail 500 drives the trigger end 140 to rotate, and the trigger end 140 is reset under the traction of the reset elastic member 200; when the guide rail 500 moves downward normally, the downward movement of the guide rail 500 drives the trigger end 140 to rotate, and the trigger end 140 drives the anti-falling end 130 to perform an elastic-in or elastic-out reset movement; when the guide rail 500 is in a falling working condition, the falling speed is greater than the reset speed of the pendulum needle anti-falling device 100, so that the anti-falling end 130 is stuck with the inner stop rod of the guide rail 500 to meet the anti-falling requirements, and two different working conditions can be realized, which is convenient for selection.
[0037] In some embodiments, it further includes an anti-falling pin shaft 300. The end of the anti-falling body 110 has a through hole 111, and the wall-attached support 400 is provided with a mounting hole. One end of the anti-falling pin shaft 300 passes through the through hole 111 and is limited in the mounting hole to rotatably mount the pendulum needle anti-falling device 100 on the wall-attached support 400. The anti-falling pin shaft 300 is used to limit the pendulum needle anti-falling device 100 to the wall-attached support 400 to prevent the pendulum needle anti-falling device 100 from detaching from the wall-attached support 400. It can be understood that the anti-falling pin shaft 300 can also be replaced with parts such as bolts and pin rods.
[0038] In some embodiments, the first hanging portion 120 is located on one side of the anti-falling body 110 away from the anti-falling end 130. Further, the second hanging portion 150 is located on one side of the anti-falling body 110 away from the trigger end 140. Through the above structure, it is convenient to stretch the first hanging portion 120 or the second hanging portion 150 of the reset elastic member 200, thereby driving the pendulum needle anti-falling device 100 to rotate.
[0039] In some embodiments, the anti-falling end 130 has an abutting edge 131 for abutting against the anti-falling stop bar 510, and a sliding edge 132 oppositely disposed relative to the abutting edge 131. The abutting edge 131 is a plane, and the sliding edge 132 is a wedge-shaped surface. Further, the triggering end 140 has a triggering edge 141, and the triggering edge 141 is a wedge-shaped surface or an arc surface.
[0040] Specifically, the above-mentioned sliding edge 132 can pop out or pop into the anti-falling stop bar 510, which is convenient for disengaging from the anti-falling stop bar 510. The above-mentioned abutting edge 131 is used to abut against the anti-falling stop bar 510 to lock the anti-falling stop bar 510 and prevent the two from disengaging. The triggering edge 141 can also pop out or pop into the anti-falling stop bar 510, which is convenient for disengaging from the anti-falling stop bar 510.
[0041] In some embodiments, the included angle between the triggering end 140 and the anti-falling end 130 is an acute angle.
[0042] In some embodiments, the first hanging portion 120 is provided with a first hanging hole 121, the second hanging portion 150 is provided with a second hanging hole 151, and the included angle between the first hanging hole 121 and the second hanging hole 151 is a right angle. The reset elastic member 200 can be connected to the first hanging hole 121 or the second hanging hole 151. The first hanging hole 121 and the second hanging hole 151 facilitate the detachable connection with the reset elastic member 200. The distance between the first hanging hole 121 and the anti-falling end 130 is greater than the distance between the second hanging hole 151 and the anti-falling end 130.
[0043] Specifically, the reset elastic member 200 is a reset spring. It can be understood that in some structures, the reset elastic member 200 can also be a spring sheet, a compression spring, etc.
[0044] In summary, the multi-condition pendulum needle anti-falling structure of the present invention has at least the following advantages:
[0045] 1. One pendulum needle anti-falling device 100 can achieve the lifting condition and the only-lifting-and-no-dropping condition;
[0046] 2. The only-lifting-and-no-dropping condition is safer and more reliable, and the pendulum needle anti-falling device 100 is always in the anti-falling state;
[0047] 3. It can realize the arbitrary conversion of the two conditions according to the project requirements.
[0048] In the embodiment of the present utility model, the climbing frame includes a guide rail 500 and an attached wall support 400 connected to the guide rail 500. The guide rail 500 is provided with a plurality of anti-falling retaining bars 510 arranged at intervals. The above-mentioned multi-condition pendulum needle anti-falling structure is installed on the attached wall support 400, and the multi-condition pendulum needle anti-falling structure is used to abut against the anti-falling retaining bars 510. For the specific structure of the multi-condition pendulum needle anti-falling structure, please refer to the above-mentioned embodiment and will not be elaborated here. Since the climbing frame applies the above-mentioned multi-condition pendulum needle anti-falling structure, it has all the advantages and effects of the working condition pendulum needle anti-falling structure.
[0049] The above are only the preferred embodiments of the present utility model, and do not limit the patent scope of the present utility model accordingly. Any equivalent structural transformation made by using the content of the specification and drawings of the present utility model under the inventive concept of the present utility model, or direct / indirect application in other related technical fields, is included in the patent protection scope of the present utility model.
