Abstract
The present invention relates to a kind of new rail pressing device, including base, wear pin, upper cover plate, T-bolt, spring washer, plain washer and locking nut, it is characterised in that：U-shaped pin is further included, the U-shaped pin is process by steel wire, and semicircle is processed into its end；Two bolts hole are drilled with the middle part of the upper cover plate outer ledge and by institute's drill bolt hole tapping, bolt is connected with institute's drill bolt hole；The T-bolt top is provided with ellipse or circular through hole, and the U-shaped pin through the ellipse on the T-bolt or circular through hole and bends U-shaped pin ends；The T-bolt top open ellipse or circular through hole position should ensure that locking nut screwing after, the U-shaped pin installed is located at 1~2mm of top of locking nut.This new rail pressing device, which can effectively prevent, wears pin because vibration is exited out of base and locking nut does not reach the preferable situation for compressing track because vibration unscrews, and solves the problems, such as periodically to fasten rail pressing device.
Description
First, technical field：
The present invention relates to a kind of new rail pressing device, belong to crane rail fixing device technical field.
2nd, background technology
In the prior art, the rail pressing device for fixed crane beam orbit generally includes base, wears pin, upper cover plate, T-shaped spiral shell
Bolt, spring washer, plain washer and locking nut.Tube chamber welds with base is fixed on crane girder, will be worn pin and is penetrated in base, treats gauge tune
After integrating lattice, the locking nut on upper cover plate is fastened.In practical applications, since what crane produced in the process of walking shakes
It is dynamic, it can make to wear pin and slowly be exited out of base, wear the positioning restriction effect of pin since upper cover plate loses, upper cover panel vibration can be made
Increase, so that causing locking nut to loosen does not reach preferably compression track purpose.Because track rail pressing device is large number of, periodically fastening
The work of rail pressing device is extremely cumbersome and operation process is dangerous big, and labor intensity is high.
3rd, the content of the invention：
The present invention is in view of the shortcomings of the prior art, propose a kind of a kind of easy to operate, new rail pressing device easy to use.
The technical solution adopted in the present invention：
The present invention relates to a kind of new rail pressing device, including base, wear pin, upper cover plate, T-bolt, spring washer, plain washer
And locking nut, it is characterised in that：U-shaped pin is further included, the U-shaped pin is process by steel wire, its end is processed into half
It is circular；It is drilled with two bolts hole in the middle part of the upper cover plate outer ledge and is tapped with screw thread in institute's drill bolt hole, in institute's auger shell bolt
Bolt is connected with hole；The T-bolt top is provided with ellipse or circular through hole, the U-shaped pin pass through the T-bolt
On ellipse or circular through hole and U-shaped pin ends are bent；Open oval or circular through hole in the T-bolt top
After position should ensure that locking nut screwing, the U-shaped pin installed is located at 1~2mm of top of locking nut.
The beneficial good effect of the present invention：
The configuration of the present invention is simple, it is easy to operate, it can effectively prevent and wear pin because vibration is exited and locked out of base
Nut does not reach the situation for preferably compressing track because vibration unscrews, and solves the problems, such as periodically to fasten rail pressing device.

5th, embodiment
Embodiment one：Referring to Fig. 1, Fig. 2, Fig. 3, Fig. 4, Fig. 5, include base 1 the present invention relates to a kind of new rail pressing device, wear
Pin 2, upper cover plate 3, T-bolt 4, spring washer 8, plain washer 7 and locking nut 6, it is characterised in that：U-shaped pin 5 is further included,
The U-shaped pin 5 is process by steel wire, and semicircle is processed into its end；Two are drilled with the middle part of 3 outer ledge of upper cover plate
Bolt hole and by institute's drill bolt hole tapping, bolt 9 is connected with institute's drill bolt hole；4 top of T-bolt is provided with ellipse
Or circular through hole, the U-shaped pin 5 is through the ellipse on the T-bolt 4 or circular through hole and U-shaped 5 end of pin is curved
Folding；4 top of T-bolt open ellipse or circular through hole position should ensure that locking nut 6 is tightened after, the U that is installed
Type pin 5 is located at 1~2mm of top of locking nut 6.Base 1 is weldingly fixed on crane girder first during construction, is put into T
Type bolt 4, will wear pin 2 and penetrates in base 1, then install upper cover plate 3, plain washer 7, spring washer 8 and locking nut 6 successively,
Move and wear the adjustment rail pressing device of pin 2 perpendicular to the position of orbital direction, after upper cover plate 3 and track lower flange closely compression, twist
Tight locking nut 6, bolt 9 is tightened.U-shaped pin 5 is finally penetrated into ellipse on T-bolt 4 or circular through hole and will be U-shaped
5 end of pin is bent.
Basic principle, main feature and the advantages of the present invention of the present invention has been shown and described above.The technology of the industry
Personnel are it should be appreciated that the present invention is not limited to the above embodiments, and the above embodiments and description only describe this
The principle of invention, on the premise of the essence spirit of the present invention and scope is not departed from, various changes and modifications of the present invention are possible,
The component that can be played limitation locking nut 6 and screw out that U-shaped pin 5 can also make of bolt or other materials as described in the present invention
Substituted, these changes and improvements are both fallen within the range of claimed invention.The claimed scope of the invention is by appended
