The embodiment of the present invention sets mounting bracket by installing rack on rotating ring beam on wedge bracket, on mounting bracket Lifting unit is provided with, rack is engaged with the lifter wheel in lifting unit, during being lifted in hoistable platform, Rotating ring beam and determine ring beam and alternately moved by engaging along spud leg for rack and lifter wheel, therefore avoid to promote oil The problem of hoistable platform lifting speed is slow caused by cylinder.

Fig. 3 is a kind of bottom view of composite hydraulic bolt elevating platform assembly provided in an embodiment of the present invention, with reference to Fig. 2 And Fig. 3, in one embodiment of the invention, determine to be provided with multiple first bolts 31 on ring beam 30, and multiple first bolts 31 around spud leg 10 the equiangularly spaced setting of circumferencial direction, be provided with multiple second bolts 41, and multiple second on rotating ring beam 40 Bolt 41 is distinguished around the equiangularly spaced setting of circumferencial direction of spud leg 10 by multiple first bolts 31 and multiple second bolts 41 It will determine ring beam 30 and rotating ring beam 40 be arranged on spud leg 10 and can reduce institute on each first bolt 31 and each second bolt 41 The power of carrying, simultaneously because the circumferencial direction of multiple first bolts 31 and multiple second bolts 41 around spud leg 10 is equiangularly spaced Setting, therefore the stress on multiple first bolts 31 and multiple second bolts 41 can be balanced, make to determine ring beam 30 and rotating ring beam 40 It is more steady.

In addition, the position for determining corresponding first bolt 31 on ring beam 30 is provided with the first socket 32, corresponded on rotating ring beam 40 The position of second bolt 41 is provided with the second socket 42, and the first bolt 31 is arranged in the first socket 32, the second bolt 41 It is arranged in the second socket 42.

The position for determining on ring beam 30 corresponding first plugging pin oil cylinder 35 is provided with the first cylinder rack 36, corresponding the on rotating ring beam 40 The position of two plugging pin oil cylinders 46 is provided with the second cylinder rack 47, and the first plugging pin oil cylinder 35 is arranged in the first cylinder rack 36, and second Plugging pin oil cylinder 46 is arranged in the second cylinder rack 47.

As shown in Figure 1, rack 43 can be hinged by straight pin 45 with rotating ring beam 40, straight pin 45 is perpendicular to 43 He of rack Rack 43 and rotating ring beam 40 can hingedly be made rack 43 small in appearance by the plane where lifter wheel 52 by straight pin 45 It can be rotated when deformation around straight pin 45, to reduce the stress that rack 43 is generated due to deformation.

As shown in Figure 1, device includes a plurality of rack 43, a plurality of rack 43 equiangularly spaced is set around the circumferencial direction of spud leg 10 Put, multiple mounting brackets 50 be provided on wedge bracket 20, mounting bracket 50 is arranged in a one-to-one correspondence with rack 43, every rack 43 respectively with Lifter wheel 52 on corresponding mounting bracket 50 is meshed, and by being arranged in a one-to-one correspondence mounting bracket 50 and rack 43, can increase The power of device simultaneously because a plurality of rack 43 is around 10 equiangularly spaced setting of spud leg, therefore can balance multiple mounting brackets 50 On lifting unit 51 to the power of rack 43, make the lifting for determining ring beam 30 and rotating ring beam 40 more steady, avoid determining 30 He of ring beam Rotating ring beam 40 tilts in lifting process.

Further, the first bolt 31 and the second bolt 41 are arranged in a one-to-one correspondence, and 31 He of the first bolt being correspondingly arranged Line between second bolt 41 is parallel with the axis of spud leg 10, and 43 and second bolt of rack, 41 alternate intervals are arranged on rotating ring beam On 40, the movement for determining ring beam 30 and rotating ring beam 40 can be made more steady.

Further, the axis direction of the corresponding rack 43 of each 50 upper edge of mounting bracket is provided with two row lifting units 51, Each column lifting unit 51 corresponds to one row lifter wheel 52 of driving, and the both sides of rack 43 are arranged with two row teeth, two row of rack 43 Tooth is meshed with corresponding two row lifter wheel 52, can since the both sides of every rack 43 are all engaged with lifting unit 51 So that the stress of 43 both sides of rack more balances, rack 43 is avoided to be deformed due to force unbalance.

It is envisioned that the lifting unit 51 of identical quantity is provided on each mounting bracket 50, and each column lifting unit 51 quantity is consistent, so as to further balance the stress of 43 both sides of rack, avoids rack 43 due to both sides stress injustice It weighs and deforms.

During specific implementation, lifting unit 51 can be bolted to connection on mounting bracket 50.

As shown in Figure 1, determining to be additionally provided with guide plate 33 on ring beam 30, the both sides of every rack 43 are respectively arranged with one piece and lead To plate 33, guide plate 33 is parallel to the axis setting of rack 43, since rack 43 is longer, by being set on ring beam 30 is determined Putting guide plate 33 can further avoid rack 43 from distorted deformation occur so that rack 43 can remain parallel to 10 axis of spud leg Direction.

It is envisioned that guide plate 33 and determining that between ring beam 30 floor 34 can also be set, led by the reinforcement of floor 34 To the mechanical strength of plate 33, guide plate 33 is avoided to deform.

Referring to Fig. 1, the both sides that rack 43 is corresponded on rotating ring beam 40 are respectively arranged with gusset 44, and gusset 44 is parallel to rack 43 Axis, since rack 43 is fixed on rotating ring beam 40, and need to bear very big power on rack 43, therefore on rotating ring beam 40 Setting gusset 44 can enhance the mechanical strength of rotating ring beam 40.

The course of work for the device that the embodiment of the present invention described briefly below is provided:

In uphill process, the second plugging pin oil cylinder 46 acts on the second bolt 41 and is inserted into the pin hole 11 of spud leg 10, and first Plugging pin oil cylinder 35 acts on the first bolt 31 and is extracted from the pin hole 11 of spud leg 10, and control lifting unit 51 is started to work, and is lifted Gear 52 rotates forward, and lifter wheel 52 is climb along rack 43 so that determines ring beam 30 and is moved up along the direction of spud leg 10, determines ring The distance between beam 30 and rotating ring beam 40 are elongated, so as to which wedge bracket 20 be driven to be moved up along spud leg 10 so that hoistable platform to Upper movement, when determining ring beam 30 and being moved upwards up to designated position along spud leg 10, control lifting unit 51 is stopped, while first Plugging pin oil cylinder 35 act on the first bolt 31 be inserted into spud leg 10 pin hole 11 in, the second plugging pin oil cylinder 46 act on the second bolt 41 from It is extracted in the pin hole 11 of spud leg 10, then lifting unit 51 is controlled to start to work, lifter wheel 52 rotates backward, lifter wheel 52 Position is motionless, and the rotation band carry-over bar 43 of lifter wheel 52 moves up so that rotating ring beam 40 is moved up along the direction of spud leg 10, determines ring beam The distance between 30 and rotating ring beam 40 shorten, and so recycle, realize the vertical motion of hoistable platform, the lowering action of hoistable platform It is then opposite with the process of vertical motion.

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.
