Description
Technical field
The utility model belongs to technical field of conveying machinery, specifically relates to a kind of two pin-and-hole safety locking mechanisms that are applied on the elevator drives.
Background technology
In the prior art; Elevator drives mainly is made up of drive motor, axle drive shaft, head roll and several parts of cylinder rotating disk; Drive motor is fixed on the platform, and axle drive shaft is installed on the platform through two bearing seats, and axle drive shaft is connected with the output shaft of drive motor through coupler; Head roll is installed on the axle drive shaft; In the head roll end cylinder rotating disk of following its synchronous rotation is installed, the circumferential edges of said cylinder rotating disk evenly is provided with a plurality of rotating disk grooves, is the rotating disk tooth between the adjacent discs groove.When elevator need stop, normally let drive motor cut off the power supply, stretch out in the rotating disk groove that injects on the cylinder rotating disk with a locking pin then, motor can not rotated because the accident power supply, play the effect of safety guard-safeguard.Because what it adopted is a locking pin; Only when the rotating disk groove is aimed at locking pin, just driving can be successfully locked, when the rotating disk tooth on the cylinder rotating disk is aimed at the position of locking pin, then driving can't be locked; Accident in the time of when the elevator needs are slack, just possibly taking place; Cause safety misadventure, not only have influence on the normal production order, but also may cause personnel and equipment impaired.
Summary of the invention
The purpose of the utility model is to overcome the deficiency that exists in the prior art, and a kind of two pin-and-hole safety locking mechanisms that are applied on the elevator drives are provided, and its simple and ingenious structure under any circumstance can be locked elevator drives, and is safe.
The technical scheme that provides according to the utility model: be applied to the two pin-and-hole safety locking mechanisms on the elevator drives; It is characterized in that: said pair of pin-and-hole safety locking mechanism is arranged on cylinder rotating disk side; It comprises lock bracket, auxiliary stand and locking pin; Lock bracket is fixed on the platform, and auxiliary stand is fixed on the lock bracket, leaves the passage that is used for the cylinder dial rotation between auxiliary stand and the lock bracket; The position relative with the cylinder disk edge offers two pin-and-holes that are used to insert locking pin respectively on said lock bracket and the auxiliary stand; The minor increment at said two pin-and-hole edges is greater than the rotating disk facewidth degree of cylinder rotating disk, and the ultimate range at said two pin-and-hole edges is less than the rotating disk well width of said cylinder rotating disk.
As the further improvement of the utility model, the pin support that is used to place locking pin also is installed on the said lock bracket, locking pin is placed on the pin support when being not used in the locking elevator drives.
As the further improvement of the utility model, said locking pin end joint connection has chain, and the chain other end is connected on the chain frame, and chain frame is through being bolted on the lock bracket, and chain is used to prevent that locking pin do not lose because of placing conveniently by the time spent.
The utility model compared with prior art; Advantage is: the two pin-and-hole safety locking mechanism simple and ingenious structure of the utility model; Through the position of two pin-and-holes on lock bracket and the auxiliary stand rationally is set, make elevator drives under any circumstance can lock, safe.

The specific embodiment
Below in conjunction with concrete accompanying drawing and embodiment the utility model is described further.
As shown in the figure, described pair of pin-and-hole safety locking mechanism of the utility model is applied on the elevator drives.The structure of elevator drives such as Fig. 1 ~ shown in Figure 3; It mainly is made up of drive motor 2, coupler 3, axle drive shaft 4, bearing seat 5, head roll 6 and cylinder rotating disk 7; Drive motor 2 is through being bolted on the platform 1, and axle drive shaft 4 is installed on the platform 1 through two bearing seats 5, and axle drive shaft 4 is connected with the output shaft of drive motor 2 through coupler 3; Head roll 6 is installed on the axle drive shaft 4; In head roll 6 ends the cylinder rotating disks 7 of following head roll 6 synchronous rotations are installed, the circumferential edges of said cylinder rotating disk 7 evenly is provided with a plurality of rotating disk grooves 8, is rotating disk tooth 9 between the adjacent discs groove 8.Said pair of pin-and-hole safety locking mechanism is arranged on cylinder rotating disk 7 sides, when when elevator need stop, with drive motor 2 outages, with two pin-and-hole safety locking mechanisms cylinder rotating disk 7 locked then earlier.
The concrete structure of said pair of pin-and-hole safety locking mechanism such as Fig. 4 ~ shown in Figure 6, it mainly is made up of lock bracket 10, locking pin 11, pin support 12, chain 13, chain frame 14 and auxiliary stand 15.
Said pin support 12 is installed on the lock bracket 10 through bolt, and locking pin 11 is placed on the pin support 12 when being not used in the locking elevator drives.In addition, said locking pin 11 is connected on the chain frame 14 through the chain 13 that is connected its tail end, and chain frame 14 is through being bolted on the lock bracket 10, and chain 13 is used to prevent that locking pin 11 do not lose because of placing conveniently by the time spent.
During concrete the application; When elevator need stop, drive motor 2 outages were taken off locking pin 11 from pin support 12; And insert in the rotating disk groove 8 of lock bracket 10, cylinder rotating disk 7 and that pin-and-hole 17 that auxiliary stand 15 threes are led to, thereby elevator drives is locked.When elevator need start, extract locking pin 11 and also be placed into again on the pin support 12, drive motor 2 energisings, elevator drives gets final product clean boot.
