(5) specific embodiment
Below in conjunction with the accompanying drawing and the specific embodiment the utility model is done further explain.
In conjunction with accompanying drawing 1 to 6, a kind of catching device comprises the body 1 with swing pipe 3 and pin pipe 2; Be equipped with lock pin spring 17 and lock pin 15 on the pin pipe; Body is provided with the detent configuration of corresponding lock pin, and said catching device also is provided with a kelly 7, is arranged with return spring and on-slip part 5 on the kelly; On-slip part 5 is terminal is provided with suspension ring 6; Swing pipe 3 places of said body 1 pendulum 4 that is pivoted, said kelly 7 are fixedly arranged on said pendulum 4 inboards and normal direction perpendicular to pendulum 4, and said body and pin pipe place corresponding kelly position is provided with bayonet socket 21.Said lock pin can rotate up and down in the lock pipe and exercise the lock pin function.Said return spring is sheathed on the kelly 7, between on-slip part 5 and pendulum 4, is used to drive the on-slip part and compresses rope.
Described detent configuration; Comprise that one is located on the lock pin normal direction in the protruding button 16 of lock pin; Corresponding protruding button position is provided with the loose slot 18 of an axial direction on the said pin pipe, the top of said loose slot and the peripheral side position of below be provided with upper breach 41 and the next breach 42.Select for use this structure can reduce cost, optimize structure.
Described pendulum inboard also be provided with a normal direction in pendulum can axial stretching elastic rod 8, the position of corresponding elastic rod is provided with hole clipping 9 on the said body.Said elastic rod is used for rope 30 is led.
Described pendulum 4 inboards are provided with the guide roller 10 of an axis normal direction in pendulum.Said guide roller is used for rope is used to lead and further reduces the frictional resistance of rope slip during the stage.
Said kelly has extension 11 in the pendulum outside; Said catching device also is provided with a buffer structure; Comprise that being positioned at the pendulum outside is sheathed on thrust plate 12 and thrust spring 13 on the kelly extension 11; The position of corresponding thrust plate also is provided with throw-out lever 20 on the said on-slip part 5, and the upside of said pendulum outside thrust plate 12 also is provided with a upper limit position block 19.Said thrust structure is used to increase the life-span and the return elastic force of return spring, and increases the use feel, and said upper limit position block is in order to prevent the strong collision of on-slip part and to prevent thrust spring overbending.
When stirring lock pin in the present embodiment, when stirring protruding button 16 on the lock pin protruding button being placed breach 41, be in locking state, when protruding button is positioned at down breach 42, be in open state.The frictional force that lock pin produces owing to spring force in indentation, there can be in the indentation, there self-locking.
Present embodiment when opening, need be in open state with lock pin when open closed pendulum structure, press elastic rod 8 simultaneously and make it to be lower than hole clipping 9, just can open whole pendulum 4.Except kelly 7, bayonet socket 21, lock pin 15 have the effect of security protection, elastic rod 8 and hole clipping 9 play the effect of double security protection, prevent to open the generation security incident because of mistake.
The operation principle of the buffer unit of present embodiment is as shown in Figure 6; When suspension ring 6 upwards draw; Suspension ring pulling on-slip part moves on 7 rear ends, and it is up that the throw-out lever 20 on the part of on-slip simultaneously 7 upwards promotes thrust plate 12, arrives upper limit until thrust plate 12 up contact upper limit position blocks 19.This process provides buffering except original return spring on the kelly, and the thrust spring 13 that thrust plate 12 adheres to is also stressed, plays cushioning effect.
As shown in Figure 5, when suspension ring 6 when drop-down, the return spring return that also rebounds, on-slip part 5 rear ends move down, the tight front end rope of the tooth pressure of on-slip part front end plays fixation.
Present embodiment places rope in the bend of body in use, and lock pin is in open state, and pendulum 4 is inconjunction with kelly 7 on-slip parts closure; On-slip part 5 withstands rope 30; Kelly 7 is positioned at bayonet socket 21, and elastic rod 8 is positioned at hole clipping 9, and lock pin is in locking state.
The staff hangs over the load-bearing band on the suspension ring of on-slip part; When quiescent phase, suspension ring are stressed downwards, and leverage compresses the past rope of on-slip part; The bend of rope and on-slip part, body produces the gravity that dynamic balance has been lived human body, and the staff just can be still on the rope.
In sliding phase, the staff catches rope to climb up, and suspension ring are stressed, and upwards leverage makes the on-slip part unclamp the compressing to rope, and rubbing between body, rope, the on-slip part reduces, and the staff just can easily go up sliding.
Because present embodiment pivot pipe also is provided with pendulum near the bend of body, so the space that swing needs is just little, the bend diameter is just little, good mechanical performance.
