A bottom pintle can be removed more safely and reliably, investment of personnel and auxiliary equipment is reduced, labor intensity is relieved, and preparation and removing time of tools is shortened.

Description

Pivot moving-out device at the bottom of a kind of Miter Lock Gates

Technical field

The present invention relates to pivot moving-out device at the bottom of a kind of Miter Lock Gates, relate in particular to end pivot moving-out device after the high-order roof door of large-scale Miter Lock Gates.

Background technology

Bottom Hinge for Miter lock Gate is installed on miter gate's heel post bottom, there is the function of hinge and supporting, it is the most important stressed member of miter gate, wherein end pivot mushroom head and the situation that contacts of bearing shell affect miter gate's operation, Bottom Hinge for Miter lock Gate maintenance is mainly to solve the contact site of end pivot mushroom head and bearing shell and design checking computations station diagram does not match or contact area (what require end pivot top cover and bottom girder contact area is no less than 70%) is too small, and causes end pivot mushroom head wear extent greatly or Partial ablation problem.The particularity of its structure and position can not realize current check and maintenance, generally after high-order roof door during ship lock overhaul, shifts out end pivot strip inspection, carries out Precision Machining repair process replacing etc. when serious wear.

Summary of the invention

The object of the invention is to solve traditional Bottom Hinge for Miter lock Gate and shifts out the problem existing in construction, has guaranteed that end pivot shifts out safer, more reliable; Minimizing personnel and auxiliary equipment drop into, and reduce labour intensity; Shortening Work tool prepares and throughput time.

The object of the present invention is achieved like this:

Pivot moving-out device at the bottom of a kind of Miter Lock Gates, it comprises being arranged on and under end pivot assembly, is positioned at the sliding plate on pivot working position basis, the end, on sliding plate, be interval with multiple cylindrical rolling elements, rolling element is provided with support backing plate, pivot working position basis, the described end to miter gate outside is provided with track, track is provided with travelling car, travelling car comprises height adjustable support, frame bottom is universal wheel and lockable supporting leg, prop up top of the trellis interval and also lay multiple cylinder rolling elements, between described sliding plate and support, connect by bearing pin, on end pivot assembly, connect tractive cucurbit by wire rope, on described travelling car, plane is higher than plane on pivot working position basis, the end, the discrepancy in elevation is sliding plate thickness.

Above-mentioned track has base plate.

The bottom, top cover cantilever place of above-mentioned end pivot assembly is provided with jack.

The present invention has obtained following technique effect:

It is safer, more reliable that the present invention has guaranteed that end pivot shifts out; Minimizing personnel and auxiliary equipment drop into, and reduce labour intensity; Shortening Work tool prepares and throughput time.

Accompanying drawing explanation

Below in conjunction with drawings and Examples, the invention will be further described.

Fig. 1 is plane of arrangement figure of the present invention;

Fig. 2 is work sheet of the present invention.

The specific embodiment

Pivot moving-out device at the bottom of a kind of Miter Lock Gates as shown in Figure 1-2, it comprises that being arranged on end pivot assembly is positioned at the sliding plate 3 on pivot working position basis, the end 2 for 1 time, on sliding plate, be interval with multiple cylindrical rolling elements 4, rolling element is provided with and supports backing plate 5, pivot working position basis, the described end is provided with track 7 to miter gate 6 outsides, track is provided with travelling car 8, travelling car comprises height adjustable support 9, frame bottom is universal wheel 9 and lockable supporting leg 10, prop up top of the trellis interval and also lay multiple cylinder rolling elements 4, between described sliding plate and support, connect by bearing pin 11, on end pivot assembly, connect tractive cucurbit by wire rope, on described travelling car, plane is higher than plane on pivot working position basis, the end, the discrepancy in elevation is sliding plate thickness.Described track has base plate 12.The bottom, top cover cantilever place of described end pivot assembly is provided with jack 13.

1 end of accompanying drawing pivot moving-out device layout schematic diagram: the track laying being made up of square steel and steel plate, in end pivot working position basis until extend to outside, miter gate plane of projection, forms rigid track basis; Travelling car is positioned on track, and the universal wheel of setting plays walking and supports and guide effect, stability and security when holding device work; End pivot moving-out device moves outside miter gate plane of projection behind appropriate location, uses brake surface lifting appliance, and pivot assembly at the bottom of Awaiting Overhaul is lifted to brake surface, carries out service work.

2 end of accompanying drawing pivot moving-out device work sheet: when travelling car is basic near end pivot working position, the elevating mechanism of runing rest, make on travelling car plane higher than plane on pivot working position basis, the end, the discrepancy in elevation is sliding plate thickness, when the door storehouse degree of depth is different, set up adjusting support, the locking supporting leg of lock bracket, placement moves horizontally; Sliding plate is connected by bearing pin with travelling car, places the cylindrical rolling element of some on it, reduces resistance when pivot moves at the end; After end pivot moves on travelling car by working position, rotate positioning bolt, place jack support backing plate and lay support jack, for supporting and pivot assembly of the firm end.

Below in conjunction with pivot moving-out device example at the bottom of the Miter Lock Gates of No. one, two, Ge Zhou Ba, for the present invention is described in further detail, but practical range of the present invention, mode are not limited in this.

Miter gate is the important dash equipment of ship lock, and end pivot assembly is installed on miter gate's heel post bottom, is the most important stressed member of miter gate, and operation is frequent, is listed in most important maintenance component in planned overhaul.

True step: 1) the about 320mm of door body top lifting height, the basis levelling of door storehouse; 2) track body of laying depth δ 10mm steel plate and 40 × 40mm square steel composition; 3) rigid platfor travelling car is lifted on track body, carries out on earth by pivot working position basis; 4) spiral regulating device of adjusting (hoisting) support, makes plane on rigid platfor travelling car flush (slightly high, the discrepancy in elevation is sliding plate thickness) with plane on pivot working position basis, the end, leg locking; 5) under end pivot assembly, lay sliding plate, cylindrical rolling element (round steel φ 12-800), support backing plate, and sliding plate is connected with rigid platfor travelling car pin; 6) 5 tons of tractive cucurbits are laid in miter gate baseplane, be pivoted and connect by wire rope, shackle and the end, at the bottom of tractive pivot to rigid platfor travelling car, pivot top cover cantilever place at the bottom of two 3.2 tons of mechanic jacks topmasts, simultaneously bottom platform, positioning bolt locks; 7) regulate (decline) spiral regulating device, remove lower margin and lock on track and other constraint; 8) 5 tons of sides Chain block traction rigid platfor travelling car, shifts out end pivot outside miter gate plane of projection; 9) brake surface crane lifting end pivot, to brake surface, completes end pivot and removes the work of shifting out.
