Description
Technical field
Tower crane auxiliary equipment technical equipment field is the utility model is related to, more particularly to a kind of gear shaft terminal baffle plate fixes dress
Put.
Background technology
Last time tower crane is used as most popular derrick crane, and the slew gear on upper bracket, upper undersetting is by turning round branch
Hold and be connected, wherein slew gear is external gear, and pivoting support is external gear, and slew gear rotates to be driven up and down by pivoting support
Bearing produces rotation, and because the rotation ratio that each manufacturer requires differs, and pivoting support is standard size, therefore can only be led to
The change slew gear output gear number of teeth is crossed to change gearratio, while slew gear is also standard type, its internal structure is identical；
In the prior art, major way has two kinds, and one kind is output gear and output shaft is integral type, another kind be output gear with it is defeated
Shaft is combination assembled；Wherein the first tower crane for being only applicable to one model of a producer, batch is small, is not easy to tissue life
Production；It can be mass-produced for second, configured just according to different output gears according to customer requirement during delivery.
The defects of prior art, is：As shown in the existing gear shaft terminal baffle plate fixed forms of Fig. 3, due to output gear with it is defeated
Shaft has certain gap by spending strong connection, while tower crane requires that left and right is not stopped, and baffle plate is under alternate motion operating mode
Rotation is followed, and bolt is integrally fixed at pivot position, the athletic meeting of alternation makes bolt looseness, in work certain time
Afterwards, bolt once departs from output shaft, may result in output gear and departs from from output shaft, because tower crane is aerial lift device,
More than hundred meters are highly even up to, is dropped after gear departs from from high-altitude, serious accident can be caused.
Utility model content
In order to solve the above technical problems, the utility model provides a kind of gear shaft terminal baffle fixing, for existing
Deficiency in technology, using two bolt fixed dams, and two bolts avoid pivot position, are set at nut position
Pin-and-hole, bolt are combined as a whole the nut of two bolts with night bolt after tightening, and baffle plate will not follow output gear to rotate,
Bolt can not possibly loosen.
To reach above-mentioned purpose, the technical solution of the utility model is as follows：A kind of gear shaft terminal baffle fixing, including
In output shaft, output gear, baffle plate, bolt, nut, night bolt, axle external gear, output inner circular tooth, output outer shroud tooth, rotation
The heart, it is characterised in that：
The output shaft end is provided with axle external gear, and the axle external gear upper spline is connected with output gear, institute
State and output inner circular tooth, output outer shroud tooth are provided with output gear；The output shaft end non-rotary central position is provided with two
Individual screw, the output shaft end are provided with baffle plate, be provided with the baffle plate matched with screw morpheme set positioning hole, two
Individual bolt is spirally connected through positioning hole with the screw on output shaft is fixed on output shaft end by baffle plate；Set on the nut of the bolt
Be equipped with pin-and-hole, in the pin-and-hole on the nut of two bolts grafting be fixedly installed night bolt.
Centre distance between two bolts is less than effective fixing length of the night bolt；The position of the bolt
Putting ensures that the night bolt is located at the baffle interior.
The diameter matches of pin-and-hole and night bolt on the nut are set.
The external diameter of the baffle plate is more than the output shaft end external diameter, and the baffle plate is used to stop that output gear is deviate from.
Operation principle of the present utility model is：Baffle plate is fixed by two bolts, bolt head draw-bore, after bolt is tightened
Two bolts are combined as a whole by pin-and-hole with night bolt；This mode will not in the centre of gyration, baffle plate due to bolt
Rotated with output gear, bolt does not use spring washer locking, is drilled by nut and is combined as a whole by night bolt, it is impossible to produces pine
Dynamic, above method effectively prevents output gear from coming off, and solves security incident and falls into the generation suffered from.
Pass through above-mentioned technical proposal, the beneficial effect of technical solutions of the utility model are：Consolidated using baffle plate by two bolts
It is fixed, and two bolts avoid pivot position, set at nut position pin-and-hole, bolt tighten after with night bolt by two
The nut of bolt combines as a whole, and is connected to by night bolt in nut pin-and-hole, because bolt will not in the centre of gyration, baffle plate
Output gear can be followed to rotate, spring washer is locking, and conjuncted two bolts can not possibly produce loosening, the design so bolt need not use
Effectively prevent output gear from coming off, solve the potential problem that security incident occurs.
