Detailed description of the invention
Below in conjunction with specific embodiment, this utility model is further described:
A kind of falling proof device for climbing frame, including the anti-fall centering block body being provided with pin-and-hole 5, described anti-fall centering block body is provided with the top braking feeler 1 for withstanding anti-fall lever 7 when guide rail 8 drops suddenly, for coordinating the bottom feeler 2 driving anti-fall centering block body to rotate with anti-fall lever 7 and for keeping off the tail balancing weight gear angle 3 playing braking effect on bearing baffle plate 13, described top braking feeler 1 inside and bottom feeler 2 inside between be provided with the bayonet socket 6 for blocking adjacent two anti-fall levers 7, it is provided with back-moving spring fixing hole 4 outside described top braking feeler 1, described back-moving spring fixing hole 4 is provided with the back-moving spring 10 with support reinforcing plate 9.The anti-fall centering block body at described bayonet socket 6 back side is provided with the first circular arc R 1 more smoothed out for making anti-fall centering block body rotate.It is provided with inside described top braking feeler 1 for can guarantee that the second circular arc R 2 that can smoothly pass anti-fall lever 7 inside top braking feeler 1.Smooth and without the three-arc R3 paused when being provided with between inside described bottom feeler 2 for ensureing anti-fall lever 7 portion's feeler 2 under a touch.
It is installed on wall-attached supporting seat 12 reserved location by anti-fall bearing pin 11；Back-moving spring 10 two ends connect back-moving spring fixing hole 4 and support reinforcing plate 9 respectively, during lifting by anti-fall lever 7 at the uniform velocity lift realize anti-fall centering block body to climbing frame normal condition without interfering movement, fall when support body goes wrong, under anti-fall centering block body self gravitation and support body gravity are interfered, complete braking；Anti-fall centering block body blocks anti-fall lever 7 by support reinforcing plate 9 makes support body stop tenesmus.
Without installing back-moving spring 10 when climbing frame promotes: start liftings → anti-fall lever 7 at the uniform velocity rise → drive anti-fall centering block body at the uniform velocity rise (see Fig. 4) → be promoted to two adjacent anti-fall levers 7 be concurrently placed in bayonet socket 6 (see Fig. 5) → support body fault and quickly drop → tail balancing weight keeps off angle 3 reset → on-position under gravity (see Fig. 3).
Climbing frame installs back-moving spring 10 before declining: begin to decline → back-moving spring 10 anti-fall centering block body is moved to appointment position (see Fig. 7) → the anti-fall lever 7 uniform descent → anti-fall centering block body bottom to extreme position (see Fig. 8) → support body fault quickly drop → anti-fall centering block body cannot under back-moving spring 10 acts on reset → on-position (see Fig. 6)
In lifting process, pendulum model catching device top braking feeler 1 and bottom feeler 2 lay respectively at the top and bottom place of adjacent two anti-fall levers 7 on guide rail 8, guide rail 8 is by the uniform velocity promoting, on guide rail 8, anti-fall lever 7 also word speed promotes, top braking feeler 1 is after by first anti-fall lever 7 place, owing to tail balancing weight keeps off angle 3 active force backward, top braking feeler 1 is back to bottom first anti-fall lever 7, and reach capacity state.If now guide rail 8 drops suddenly, anti-fall lever 7 drops on top braking feeler 1, and tail balancing weight gear angle 3 keeps off on bearing baffle plate 13, plays braking effect.
In decline process, back-moving spring 10 need to be installed, guide rail 8 is when declining, top braking feeler 1 held by back-moving spring 10, it is made not affect anti-fall lever 7 uniform descent on guide rail 8, the anti-fall lever 7 in lower section by bottom feeler 2 brought into motion, makes top braking tentacle return to anti-fall lever 7 top when declining, and reach capacity state.If now guide rail 8 drops suddenly, anti-fall lever 7 drops on top braking feeler 1, and bottom tail balancing weight gear angle 3 keeps off on bearing baffle plate 13, plays braking effect.
Second circular arc R 2 radius is 67mm, it is ensured that top braking feeler 1 can smoothly pass anti-fall lever.Feeler 1 is braked on the top that is shorter in length than of bottom feeler 2, and three-arc R3 radius is 74mm circular arc, it is ensured that smooth less without pause and amplitude of fluctuation during anti-fall lever portion's tentacle under a touch.Pin-and-hole back adopts radius 34mm circular arc so that it is more smooth out when doing pendulum model motion.Bayonet socket 6 A/F d is 57mm, it is ensured that when limit state, and bottom feeler 2 and top braking feeler 1, all the time at the upper and lower side of adjacent two anti-fall levers 7, play anti-fall effect.
