Description
Technical field
This utility model relates to a kind of arm-tie pin shaft fixing device, belongs to bearing pin interconnection technique field.
Background technology
Along with the development of hoisting engineering, lifting altitude, hanging load and be continuously increased, lifting environment such as the unfavorable factor such as wind, vibration, ground environment is also the most severe, and it is increasing that this allows for crawler crane arm-tie power, and gets more and more its interference.Multi-disc arm-tie is to be assembled by multiple plates, in use need hole close alignment in many sheet, and manufacturing, assembling, transport, installation process inevitably has deviation, time one is long, arm-tie will be dehisced, this allows for during lifting, and arm-tie bearing pin can be by axial component, during adding use, jib rocks, wind, vibration, the unfavorable factors such as the unbalance loading amplification to this component, arm-tie can be caused to fix cut off with hollow safety pin, early stage strengthens hollow safety pin spring wire diameter to prevent from being cut off, but thus make the outer deformation of hollow safety pin big, easily beyond arm-tie head configuration size, interference is caused to drop with other parts, cause the accident.
Utility model content
For solving the deficiencies in the prior art, the purpose of this utility model is to provide a kind of arm-tie pin shaft fixing device, can effectively solve multi-disc arm-tie and dehisce to cut off fixing hollow safety pin, solve hollow safety pin stress difference problem and touch other parts and major safety problems that easily passive open causes bearing pin to come off.
In order to realize above-mentioned target, this utility model adopts the following technical scheme that:
A kind of arm-tie pin shaft fixing device, is used for fixing the combination of multi-disc arm-tie, it is characterized in that, including the first bearing pin, sleeve pipe, the second bearing pin and fixed component；Described first bearing pin and sleeve pipe match, and the first bearing pin is provided with the first connecting hole, and sleeve pipe is provided with the second connecting hole；The inwall of described first connecting hole and the second connecting hole all outer walls with the second bearing pin match；One end of described second bearing pin is provided with the 3rd connecting hole；Described fixed component fixes the second bearing pin by the 3rd connecting hole in the outside of sleeve pipe.
Aforesaid a kind of arm-tie pin shaft fixing device, is characterized in that, the head of described second bearing pin is set to the cylinder that cross section is slotted hole shape, and the shaft diameter of the second bearing pin is identical with the width of head.
Aforesaid a kind of arm-tie pin shaft fixing device, is characterized in that, described second connecting hole uses the slotted hole shape with the second bearing pin fit heads.
Aforesaid a kind of arm-tie pin shaft fixing device, is characterized in that, described second bearing pin and the unidirectional coupling of the second connecting hole.
Aforesaid a kind of arm-tie pin shaft fixing device, is characterized in that, described fixed component uses fixing card or split pin or spring catch.
The beneficial effect that this utility model is reached: 1. installing sleeve pipe and can limit arm-tie and dehisce, the second pin diameter is big, and has two shear surfaces, and stress is good；2. contour structures is little, without departing from arm-tie head sizes, will not cause interference, cause the security incident that bearing pin comes off；3. this device is designed with Anti-error structure, and the second bearing pin reversely cannot be installed；4. in this device, the second bearing pin is coordinated with slotted hole on sleeve pipe by its head, limits the rotation of self so that arm-tie can normally use in the relatively adverse circumstances such as wind energy turbine set.
Accompanying drawing explanation
Fig. 1 is the structural representation of this device；
Fig. 2 is the front view of the second bearing pin；
Fig. 3 is the top view of the second bearing pin；
Fig. 4 is the left view of the second bearing pin；
Fig. 5 is the fixed form structural representation of existing bearing pin.
The implication of reference in figure:
101-the first connecting hole, 102-the second connecting hole, 103-the 3rd connecting hole, 2-the first bearing pin, 3-arm-tie, 4-the second bearing pin, 5-sleeve pipe, 6-fixed component.
Detailed description of the invention
Below in conjunction with the accompanying drawings this utility model is further described.Following example are only used for clearly illustrating the technical solution of the utility model, and can not limit protection domain of the present utility model with this.
This device can effectively solve multi-disc arm-tie 3 and dehisce to cut off fixing hollow safety pin problem, thus reaches the purpose of fixing arm-tie 3 bearing pin；Existing hollow safety pin fixed form can be replaced, solve hollow safety pin stress difference problem, touch other parts and major safety problems that easily passive open causes bearing pin to come off.
This device is carried out the most as follows:
1) thickness and consideration gap after installing according to arm-tie 3 combination determine the first bearing pin 2 length, punch position.
2) to hole upper after arm-tie 3, insert the first bearing pin 2, put sleeve pipe 5.
3) align and insert the second bearing pin 4, last mounting part part 6 after the first connecting hole 101 and the second connecting hole 102.
After installation as shown in Figure 1.
Here the structure of the second bearing pin 4 is as in Figure 2-4, and the shaft diameter of the second bearing pin 4 is identical with head width, simultaneously in order to prevent from rotating after installing, has the slotted hole coordinated with small clevis pin with head head width on sleeve pipe 5.Second bearing pin 4 can only unidirectional be installed, and from sleeve pipe 5, second connecting hole 102 position penetrates, if reversely penetrate, the second bearing pin 4 length is inadequate, it is impossible to fixed component 6 be arranged on the second connecting hole 103, it is to avoid setup error during using.
Existing tradition arm-tie bearing pin fixed form, spring wire diameter is little, and only one of which shear surface, and stress is bad, it is impossible to effectively solves multi-disc arm-tie and dehisces problem.Dehiscing in contrast, the installation sleeve pipe 5 of this device can limit arm-tie 3, small clevis pin with head diameter is big, and has two shear surfaces, stress good (two shear surfaces refer to the first bearing pin and the position of the second bearing pin shearing)；Contour structures is little, without departing from arm-tie 3 head sizes, will not cause interference, cause the security incident that bearing pin comes off；Being designed with Anti-error structure, the second bearing pin 4 reversely cannot be installed；Second bearing pin 4 coordinates with the slotted hole on sleeve pipe 5 due to its head, limits the rotation of self so that arm-tie 3 bearing pin can normally use in the relatively adverse circumstances such as wind energy turbine set.
The above is only preferred implementation of the present utility model; should be understood that; for those skilled in the art; on the premise of without departing from this utility model know-why; can also make some improvement and deformation, these improve and deformation also should be regarded as protection domain of the present utility model.
