Specific embodiment
The utility model is described in further detail below in conjunction with attached drawing.
It referring to Fig.1, is deep foundation pit construction disclosed by the utility model work supporting platform, including suspension device 1 and protection
Slope 2.Protecting slope 2, there are four surround the setting of 1 surrounding of suspension device.
Referring to Fig. 2, suspension device 1 includes protection department 3, support portion 4, lifting unit 5, fixing piece 6.
Protection department 3 is arranged in the top, plays protective action.Support portion 4 is fixed on 3 bottom of protection department, plays support and makees
With.The square pillar 13 that support portion 4 is fixed on 3 bottom of protection department by four forms.It is arranged between support portion 4 and protection department 3
There is fixing piece 6.Fixing piece 6 is the reinforcing rib of triangular shape, and wherein the two sides right-angle side of reinforcing rib is separately fixed at the bottom of protection department 3
In portion and pillar 13.
The setting of lifting unit 5 is in 4 downside of support portion.Lifting unit 5 includes screw rod 51, screw rod bushing 52, synchronizing wheel 14, transmission chain
15, rolling bearing and socle 19.For screw rod 51 there are four being fixedly connected respectively with 13 bottom of surrounding pillar, screw rod bushing 52 is socketed in silk
It is threadedly coupled on bar 51 and with screw rod 51, there are four be separately fixed on screw rod 51 synchronizing wheel 14.There are four pass through rolling to socle 19
Dynamic bearing is connect with screw rod 51 respectively.The inner ring of rolling bearing is fixedly connected with screw rod bushing 52, the outer ring and socle of rolling bearing
19 are fixedly connected.The driving device 16 that driving screw rod bushing 52 rotates is provided on a wherein screw rod bushing 52.
Driving device 16 includes the first angular wheel 20, the second angular wheel 21, driving motor 17 and support driving motor
17 support frame.First angular wheel 20 is socketed on one of screw rod bushing 52 and coaxially fixes, the second angular wheel
21 engage with the first angular wheel 20, and the output shaft of driving motor 17 is fixedly connected with 21 axle portion of the second angular wheel.
Referring to Fig. 3, protection department 3 includes the first protective net 7, the second protective net 8, third protective net 9, mounting plate 10 and buffering
Part 11 is from top to bottom arranged successively as the first protective net 7, bolster 11, the second protective net 8, bolster 11, third protective net
9, mounting plate 10, and the first protective net 7, the second protective net 8, third protective net 9 arrange from large to small according to mesh aperture.
First, second and third protective net is the net being compiled by stainless steel wire, has higher protection intensity.At the top four of the first protective net 7
It is provided with corner portion 12 week.Bolster 11 is the Rectangular Spring along the outer shape setting of the first protective net 7.
Protection slope 2 tentatively prevents the Tu Bi in deep basal pit from caving in suspension device 1, and protective device further anticipates to Tu Bi
Outer landslide protection, support portion 4 support protection department 3, form construction space 18 on the downside of protection department 3.
In use, can be according to construction environment, and then judge that construction space 18 is needed by driving driving motor 17 to drive
The rotation of second angular wheel 21, and then engaged transmission the first angular wheel 20 rotation, drive one of screw rod bushing 52 to rotate, lead to
It crosses synchronizing wheel 14 and transmission chain 15 synchronizes transmission, so that four screw rod bushings 52 rotate synchronously, so that four screw rods 51
