Description
Technical field
The present invention relates to a kind of self-elevating platform up-down systems, especially a kind of machine for self-elevating platform up-down system
Tool locking device.
Background technology
Pinion and-rack jacking system is divided into two kinds by whether climbing gear is directly driven by gear-box.Directly drive form
Jacking system, gear-box output gear, which is directly engaged with rack, to climb.The jacking system of indirect driving, gear-box output
There are one-stage gear transmissions between tooth and the tooth that climbs.The distinguishing feature of indirect driving jacking system is the knot for having exposed gear
Structure, mechanical drive principle are as shown in Figure 1.In the type jacking system, the output gear 21 of gear-box 23 is same with the tooth that climbs
20 coaxial gear wheel engagements are taken turns, gear wheel is welded on climbing gear 20 on a sleeve, and torque is passed by sleeve from gear wheel
It is delivered on climbing gear 20, climbing gear 20 engages band moving platform 24 with spud leg rack 22 and lifts.The output gear of gear-box 23
21, climbing gear 20 and coaxial gear wheel three are exposed to outer.The locking of the type jacking system passes through gear-box at present
The motor 25 of input terminal itself brakes to realize.
Motor brake locking has the following disadvantages:
1）The permanent stand under load of platform self-sustaining state brake, and brake and be exposed in marine climate environment, maintaining is not good at
Platform easily occurs to fall into the sea disaster.
2）Due to permanent stand under load, also resulting in the transmission parts such as motor, gear-box, output gear can not dismantle, repair.
3）Brake is by moment of friction into line-locked, and when meeting complex environment, the moment of friction of generation may
It reduces, friction slip, safety is made to reduce.
The content of invention
The present invention provides a kind of for the detachable of pinion and-rack jacking system for indirect driving jacking system
Mechanical locking device, after locking device work, the components such as motor, gear-box, gear-box output gear can unload completely, greatly
Width improves service life, and can detachable maintaining replacement at any time as needed.The safety of new type of locking device is also much higher than original
Brake type is locked.
To achieve the above object, the technical scheme is that：It is a kind of to be used for the detachable of pinion and-rack jacking system
Formula mechanical locking device, including installation frame, lock-teeth block, lock-teeth block are mounted in installation frame, when locking locked tooth wheel
When rotation, locked tooth is made by lozenges using wedge-shaped brought into linear contact, the lock-teeth block between the lock-teeth block and locked tooth wheel
Wheel pre-tightens or generates fine motion, realizes that load is shifted or distributed between different lifting unit.
Spacing, the compression that lock-teeth block passes through installation frame upper end are equipped between the lock-teeth block and the upper surface of installation frame
Unloading is fixed or unclamped to bolt presses, facilitates taking-up lock-teeth block；After locked tooth wheel change in location, the lock-teeth block passes through position
Adjustment structure adjusts the contact position between locked tooth wheel, ensures line contact.
It is fixedly connected with cantilever slab on the installation frame, the cantilever end of the cantilever slab is equipped with voussoir hold-down bolt and locking
Nut, voussoir hold-down bolt connect lock-teeth block by wedge block, push wedge block when voussoir hold-down bolt is inwardly adjusted, make wedge shape
The inclined-plane of block and lock-teeth block coordinates, and lock-teeth block is moved to locked tooth wheel side, until lock-teeth block is contacted with locked tooth wheel, latching is locked
Gear then tightens stop nut and fixes locked position.
The beneficial effects of the invention are as follows：
1）The locking device intensity and locking rigidity of the present invention can be designed with very big allowance, safety and service life
More than brake belt length, platform can at sea control oneself throughout the year；
2）The locking device of the present invention is detachable, realizes that unlock, unlock rear platform still can be lifted normally.Platform liter
Locking can be reinstalled after dropping to position.It is reusable.
3）After the locking device of the present invention completes locking, platform load can be carried all by locking device, and allow motor, tooth
The components such as roller box, gear-box output gear unload completely, can dismantle, repair；
4）The locking device of the present invention is by limiting output gear, gear wheel, climbing gear and rack this four exposures
The movement of the gear wheel in moving component outside is locked to realize, is compared to the fortune of the first order transmission parts such as limitation rack
Dynamic mode carry it is smaller, installation weight mitigate, product structure size it is small, install additional it is more convenient, practicability is stronger.
Description of the drawings
Fig. 1 is the mechanical drive principle figure of indirect driving jacking system；
Fig. 2 is the detachable mechanical locking device schematic diagram for pinion and-rack jacking system of the present invention；
Fig. 3 is the vertical view of Fig. 2.
Specific implementation mode
The invention will be further described with embodiment below in conjunction with the accompanying drawings.
Such as Fig. 2, shown in 3, a kind of detachable mechanical locking device for pinion and-rack jacking system, including locked
Gear 1, upper lock-teeth block 3, cover board 4, installation frame 5, lock-teeth block hold-down bolt 6, bolt 7, back tightening nut 8, hangs lower lock-teeth block 2
Arm plate 9, voussoir hold-down bolt 10, stop nut 11, wedge block 12.
Upper lock-teeth block 3 or lower lock-teeth block 2 are mounted in installation frame 5, and installation frame 5 is fixed on platform, two pieces of cantilevers
Plate 9 is fixed by bolts on installation frame 5, and the cantilever end of cantilever slab 9 is equipped with voussoir hold-down bolt 10, voussoir hold-down bolt 10 to
In adjust and will push wedge block 12, wedge block 12 and upper lock-teeth block 3 or 2 inclined-plane of lower lock-teeth block coordinate, and make lock-teeth block to locked tooth
Side movement is taken turns, until lock-teeth block is contacted with locked tooth wheel 1, platform is locked, and then tightens stop nut 11.Upper lock-teeth block 3 or
Lower lock-teeth block 2 is compressed with lock-teeth block hold-down bolt 6 with the gap of installation frame 5 in-between and is eliminated, locking with back tightening nut 8,
It finally loads onto cover board 4 and tightens installation bolt 7, entire assembly is completed.When needing hoistable platform, lock-teeth block should take out.It unclamps and adjusts
The lock-teeth block hold-down bolt 6 and back tightening nut 8 of upper and lower gap are saved, the prepsetting gap between upper lock-teeth block 2 and installation frame 5 can open
Dynamic jacking system rises by platform fine motion, and load is made to be transferred back to jacking system.Then the adjusting of lock-teeth block position is unclamped again
Dependency structure unclamps cantilever slab 9, takes out wedge block 12, unclamps bolt 7 and removes cover board 4, lock-teeth block 3 or lower lock-teeth block in pull-out
2.It is installed in installation frame 5 when needing fixed platform again next time, then upper lock-teeth block 3 or lower lock-teeth block 2, passes through locking
The position of structure is adjusted makes lock-teeth block and Gear Contact again, and be finally locked platform.
The innovative point of the present invention：
1）New locking device is inhibited using the rotation of lock-teeth block opposite opened gear to lock.Lock-teeth block and gear connect
Touch using wedge-shaped brought into linear contact, wedge surface structure not by the stringent limitation of gear shape, in the case that no design of gears parameter still
It can be applicable in.Lock-teeth block can make exposed gear pre-tighten or generate fine motion by wedge surface, complete load and turn between different lifting units
It moves or distributes.
2）The new lock-teeth block of locking device and the upper surface of installation frame are designed with spacing, pass through the compression spiral shell of frame upper end
Bolt is fixed, and lock-teeth block can be unloaded by unclamping bolt, facilitate taking-up lock-teeth block, lock-teeth block that peace may be reused
Dress, lock-teeth block can ensure that line contacts by the adjustment of position adjustment structure after gear position changes.
