Specific implementation mode
To make the object, technical solutions and advantages of the present invention clearer, below in conjunction with attached drawing to embodiment party of the present invention
Formula is described in further detail.
Fig. 1 is a kind of front view of rack-and-pinion lifting gear provided in an embodiment of the present invention, as shown in Figure 1, the device
Including the ring beam 20 being sleeved on the spud leg 10 of hoistable platform, it is arranged at intervals with multiple pin holes in the axial direction on spud leg 10
12, it is additionally provided with lifter rack 11 in the axial direction on the side wall of spud leg 10, ring beam 20 is connect with the main deck 30 of hoistable platform,
Lifting unit 21 is provided on ring beam 20, Fig. 2 is a kind of vertical view of rack-and-pinion lifting gear provided in an embodiment of the present invention,
As shown in Fig. 2, lifting unit 21 includes lifter wheel 21a and the actuating unit 21b for controlling lifter wheel 21a rotations, rise
Drop gear 21a is engaged with lifter rack 11, the bolt 22 being oppositely arranged with pin hole 12 is additionally provided on ring beam 20 and for controlling
Bolt 22 processed is inserted into the plugging pin oil cylinder 23 of pin hole 12, and Fig. 3 is a kind of structural schematic diagram of bolt provided in an embodiment of the present invention,
As shown in figure 3, bolt 22 is frustum cone structure, and the diameter of one end of the close pin hole 12 of bolt 22 is less than the separate of bolt 22
The diameter of one end of pin hole 12.
The gearbox that each lifting unit 21 may include motor, be connect with motor reel, lifter wheel 21a, which is arranged, to exist
On output shaft of gear-box.
The embodiment of the present invention on ring beam by installing lifting unit, the liter on lifter wheel and spud leg in lifting unit
Drop rack is engaged so that hoistable platform and spud leg may be implemented to lift, and by the way that bolt is arranged on ring beam, bolt is round platform
Structure, and when bolt is inserted into pin hole, the diameter that bolt is inserted into one end in pin hole is less than bolt and ring beam company
The diameter of the one end connect so that after hoistable platform or spud leg are elevated to certain altitude, when bolt is inserted into pin hole, with
The lateral wall of the insertion of bolt, bolt can be in contact with the madial wall of pin hole, without control hoistable platform or spud leg
Continue to decline a distance, simplifies control process, shorten control time.
In the present embodiment, the end face of ring beam 20 is in octagon, and lifting unit 21 and bolt 22 are separately positioned on ring beam 20
Different side walls on, can excessively concentrate and lead for installing the mounting hole of lifting unit 21 and bolt 22 to avoid on ring beam 20
The mechanical strength of 20 part of ring beam is caused to decline.
It should be noted that in other embodiments, ring beam 20 can also be arranged in other shapes, such as hexagon, this
Invention is not limited thereto.
In addition, multiple gusset 20a can be arranged on ring beam 20, the machinery of ring beam 20 can be increased by the way that gusset 20a is arranged
Intensity improves the bearing capacity of lifting gear.
Preferably, the taper of bolt 22 can be 1：20~1：10, the too small then bolt of taper 22 is being inserted into pin hole 12
It can be difficult to contact with pin hole 12 in the process, taper is excessive, and after bolt 22 is inserted into pin hole 12, bolt 22 can be by
The larger power opposite with 22 direction of insertion of bolt so that plugging pin oil cylinder 23 need to provide larger thrust to avoid bolt 22 from
Deviate from pin hole 12.
Further, the shape of the madial wall of pin hole 12 is identical as the shape of the lateral wall of bolt 22, so as to increase
After big bolt 22 is inserted into pin hole 12, the contact area of bolt 22 and pin hole 12.
Realize that ground, pin hole 12 are circular hole, the diameter of one end of the separate pin hole 12 of bolt 22 can be more than pin hole
12 diameter, as long as so that control bolt 22 is inserted into pin hole 12, the lateral wall of bolt 22 is bound to and pin hole
12 madial wall contact.
Preferably, it is arranged at intervals with multiple lifter racks 11 on spud leg 10, is arranged at intervals with around spud leg 10 on ring beam 20 more
Row lifting unit 21 reduces the load that single tooth is born, so as to improve the bearing capacity of hoistable platform.
In the present embodiment, two lifter racks 11, two lifter racks 11 are arranged at intervals on the lateral wall of spud leg 10
180 ° of settings are spaced around spud leg 10, more lifter racks 11 can also be set in other embodiments, and the present invention is not with this
It is limited.
Fig. 4 is a kind of side view of rack-and-pinion lifting gear provided in an embodiment of the present invention, as shown in figure 4, lifting tooth
Item 11 includes symmetrically arranged two row tooth, and the flank of tooth of two row teeth is reversed, and each column tooth in two row teeth rises with a row respectively
The lifter wheel 21a of drop unit 21 is meshed so that the both sides of lifter rack 11 by identical power, avoid lifter rack 11 to
Unilateral side bends.
Referring again to 2, be arranged at intervals with multiple guide pads 40 between ring beam 20 and spud leg 10, guide pad 40 and spud leg 10 it
Between be equipped with gap, lifting gear can be made when being tilted on spud leg, timely prevention angle of inclination continues to increase.
Realize ground, the gap between guide pad 40 and spud leg 10 can be 1~2mm, so as to avoid lifting gear from existing
Occur larger inclination on spud leg 10, improves the safety of device.
Preferably, multiple bolts 22 are provided on ring beam 20, and multiple bolts 22 are around 10 equiangularly spaced setting of spud leg, stake
10 upper edge of leg has been provided at circumferentially spaced multiple row pin hole 12, so as to reduce and balance the power that each bolt 22 is born, together
When ring beam 20 can also be made more steady.
In the present embodiment, there are two bolts 22, two bolts 22 to be spaced 180 ° of settings around spud leg 10 for setting on ring beam 20,
In other embodiments, more bolts 22 can also be set, and the present invention is not limited thereto.
It, can be in addition, lifter rack 11 and pin hole 12 angularly alternate setting on the circumferencial direction of spud leg 10
Balance acts on the power on spud leg 10 by lifter rack 11 and pin hole 12, and spud leg 10 is avoided to occur bending and deformation, and improves and rises
The safety of platform is dropped.
In addition, the position for corresponding to bolt 22 on ring beam 20 is provided with socket 24, bolt 22 can be arranged in socket 24
In, the installation of bolt 22 can be facilitated, can additionally facilitate and other dependency structures are set on socket 24, such as examining
Survey whether bolt is inserted into the position sensor in pin hole.
The position that plugging pin oil cylinder 23 is corresponded on ring beam 20 is provided with oil cylinder seat 25, in order to the installation of plugging pin oil cylinder 23.
It should be noted that the quantity of lifter rack 11 shown in Fig. 1~Fig. 4 that the embodiment of the present invention is provided,
The quantity of the quantity of lifting unit 21, the quantity of bolt 22 and guide pad 40 is only for example, and the present invention is not limited thereto.
The foregoing is merely presently preferred embodiments of the present invention, is not intended to limit the invention, it is all the present invention spirit and
Within principle, any modification, equivalent replacement, improvement and so on should all be included in the protection scope of the present invention.
