Description
Technical field
The present invention relates to a kind of well lid closing device and its method of work.
Background technology
At present, people are in the circuit under repairing sewer pipe or well lid, can only because well lid is sealed by things such as sand and dust
Well lid is first struck into pine, then the osculum on well lid is caught on cleek, after gone with brute-force by well lid pull-up, and require in pull-up well lid
Process is accomplished without any letup, if careless slightly, well lid slides, and just to repeat the process again so that maintenance process becomes extremely multiple
It is miscellaneous cumbersome.
This phenomenon for more than, there is patent CN206172927U to propose using mainly by inverted jack mechanism, drawing
The device that bar, opening hook are formed realizes the unlatching to well lid, and the device passes through spanner stress and turned using jack mechanism is inverted
Change in piston, intensified our effort by the conversion of power between piston, to realize that the principle of small power lifting heavy opens well lid.
The technical scheme of above-mentioned well cover opening device, following defect be present：
1st, the device can only accomplish the effect of open manhole cover, so after use of the device, still needing to use a large amount of manpowers by well lid
Move；
2nd, manual pump depletion can be will be unable to use, so must in the device after inversion after general Manual hydraulic jack is inverted
Special jack mechanism must be used, the maintenance so to device is changed to affect again；
3rd, in use, due to well lid weight issue, higher is required to pull bar, the pull bar of general material is easily because that can not hold
The deformed damaged by external force.
To sum up 3 points, the well cover opening device is only used for the initial step for opening well lid, does not account for well lid and opens
The problems such as continuing to open, move, laying of rear well lid is opened, greatly reduces the service efficiency of the device.
The content of the invention
The present invention makes improvement regarding to the issue above, i.e. the technical problems to be solved by the invention are to provide a kind of well lid and opened

Bolt is set in gear bolt hole.
Further, lower take-up pulley and lower gear are set on another horizontal beam of framework by bearing and sleeve, under
Bearing is set in the bearing hole of take-up pulley and the bearing hole of lower gear, and bearing is set in excircle of sleeve, in lower take-up pulley bolt hole
Bolt is set with lower gear bolt hole.
Further, jack is vertical hydraulic jack.
Further, handle and oil return valve are provided with jack.
Further, draw-gear is cable wire.
Further, it is provided with cable wire fixing hole on upper take-up pulley and lower take-up pulley.
Further, the method for work of well lid closing device, the buckle of one end of the draw-gear on upper take-up pulley is stretched
Enter in the sled hole of well lid and block jail, lock the oil return valve of jack, pulling handle makes jack lifting, hook lifting pull out twine in
Draw-gear in lower take-up pulley, so as to drive lower take-up pulley to rotate, lower take-up pulley, which rotates, drives lower gear to rotate, and lower gear leads to
Crossing tape drives gear to rotate, and gear drives upper take-up pulley to rotate, and the rotation of upper take-up pulley will be packed up on upper take-up pulley
Draw-gear, one end of the draw-gear on upper take-up pulley drive well lid to open；When need to close well lid, returning in jack is rotated
Fuel tap, jack will slowly discharge decline hook, and well lid can also decline therewith until closure well head.
As illustrated, the material of Fig. 1 middle frames 1 is aluminium alloy extrusions, in the case where ensureing the intensity of framework 1, moreover it is possible to effectively
Reduce installation weight, and framework has increase supported amount at the larger position of stress, ensure that the stability of framework 1.
As shown in figure 3, hub internal bore 11A is square through hole, because the main material of framework 1 is aluminium alloy extrusions, and in sleeve
Hole 11A geomeries are identical with profile shapes size, ensure that sleeve 11 is securable on framework.Gear bearing hole 4B in Fig. 4
Several pieces of bearings 9 are included with upper take-up wheel bearing bore 2C in Fig. 5, and during assembling, bearing 9 is placed on sleeve 11, and bearing is used to be driven
During reduce mechanical load coefficient of friction, reduce part between frictional dissipation.
Shown in Fig. 2, several pieces of bolts 10 go up take-up pulley bolt hole 2B simultaneously also cross in gear bolt hole 4A, Fig. 5 in Fig. 4
It is fixed, lock gear and take-up pulley, accomplish to allow gear and take-up pulley while rotating.The assembly relation of lower gear 6 and lower take-up pulley 7
It is identical with upper part, but the size of each take-up pulley, gear have it is different.
Fig. 6 is the assembly relation of device internal mechanism after removal framework.Gear 4, lower gear 6, upper take-up pulley 2, lower receipts
Line wheel 7 is fixed in framework 1, and the lower gear 6 of gear 4 is driven by tape 3.On upper take-up pulley 7, cable wire（Fine line is used in figure
Instead of）Cable wire fixing hole 2A in Fig. 5 is fixed in one end, and cable wire is similar in lower take-up pulley 7, and the cable wire other end is consolidated on lower take-up pulley 7
Due on the hook 5B of Fig. 7 upright jacks 5.
In the operating condition, such as Fig. 5, the buckle on upper take-up pulley 2 on the cable wire other end is stretched into the sled hole of well lid 8 simultaneously
Card jail, locks the oil return valve 5C in Fig. 7 vertical hydraulic jacks 5, pulls jack handle 5A back and forth, make jack lifting, hangs
Hook 5B liftings pull out and twine the cable wire in lower take-up pulley 7, and so as to drive lower take-up pulley 7 to rotate, lower take-up pulley, which rotates, drives lower tooth
Wheel 6 rotates, and lower gear 6 drives gear 4 by tape 3, and gear 4 drives upper take-up pulley 4 to rotate, the rotation of upper take-up pulley 4
Cable wire will be packed up, because cable wire one end is stuck in well lid 8, so packing up for cable wire will take up well lid 8, because well lid 8 is unidirectionally to open
Class well lid is closed, when packing up whole cable wires, well lid will be against on framework 1 vertically.Clasped because well lid 8 is snapped, and cable wire twines
In upper take-up pulley 2, so at this moment well lid is fixed, during underground work, holding meanss.Must closure well lid 8 when, only need by
The oil return valve 5C in Fig. 7 jack is rotated, jack will slowly discharge decline hook 5C, and well lid is as gravity declines directly
To well head is covered back, buckle is taken out.
The present apparatus is converted to larger power by less power, to realize province by the Force principle of hydraulic jack device
The purpose of power.Lower gear 6 drives the torque conduction between gear 4, by the way that the large gear turn the small gear, reduces lower take-up pulley 7
Realize that the purpose of rope length is packed up in increase with the upper take-up pulley 2 of increase.Aluminium alloy extrusions framework is same lift frame intensity
When also alleviate the weight of framework as far as possible.
The foregoing is only presently preferred embodiments of the present invention, all equivalent changes done according to scope of the present invention patent with
Modification, it should all belong to the covering scope of the present invention.
