The specific embodiment
Describe preferred embodiment of the present utility model in detail below in conjunction with accompanying drawing.
Embodiment one
See also Fig. 1, Fig. 2, the utility model has disclosed a kind of ascending/decending mast, and described ascending/decending mast comprises that N organizes the lower mast of fit successively, and N is more than or equal to 3.Every group of lower mast be 1, more than 2 or 3, corresponding single mast, two mast or the many masts of forming.Present embodiment is that example is introduced the utility model with two masts, but the utility model is not limited to this, and the utility model is applicable to single mast, many masts simultaneously.Four " single mast " combination or six " single masts " that many masts are symmetrical expression are formed by combining.
The 1st joint lower mast is arranged on the pedestal, in the 2nd joint lower mast telescopic drive unit is set, and it is flexible that this telescopic drive unit can drive the 2nd joint lower mast; Top at the 2nd joint lower mast to the N-1 joint lower mast is provided with a drive respectively, the corresponding respectively configuration one transmission bar of each drive; The two ends of each transmission bar are separately fixed on the lower mast of both sides of corresponding drive lower mast of living in; Stretching under the driving of corresponding transmission bar of i joint lower mast drives the flexible of i+1 joint lower mast; Wherein, i is 2,3 ..., N-1.That is, one drive is set, the corresponding configuration of this drive one transmission bar at the top of i joint lower mast; The two ends of described transmission bar are separately fixed on i-1 joint lower mast, the i+1 joint lower mast; Wherein, i is 2,3 ..., N-1.Preferably, the bottom that the two ends of described transmission bar are separately fixed on the i-1 joint lower mast, i+1 saves lower mast.
As Fig. 9-shown in Figure 11, Fig. 9-Figure 11 is the example introduction with three joint lower masts.First segment lower mast 1 is fixed on its pedestal, and its upper end is equipped with chain (wire rope) and is gone up fixed block 7; The top is equipped with in rotating sprocket wheel (pulley) 10, the second joint lower masts power source oil cylinder 4 is housed on the second joint lower mast 2; Chain (wire rope) lower fixed seat 6 is equipped with in the 3rd joint lower mast lower end; Chain (wire rope) 9 one ends are fixed on the upper end of first segment lower mast 1, walking around the sprocket wheel (pulley) 10 of the second joint upper end fixes in the 3rd joint lower end, when upwards hoisting under the pushing tow of the second joint lower mast at oil cylinder, the sprocket wheel (pulley) that is fixed on the second joint upper end just upwards draws high chain (wire rope), thereby drive the 3rd joint lower mast to rising, the 3rd joint lower mast rate of climb is 2 times of second joint.In like manner, the utility model ascending/decending mast can be made of more lower mast joint.As: by the lower mast group that four joint lower masts are formed, be connected with the chain (wire rope) as traction between its first segment and the 3rd joint, this chain (wire rope) is walked around the rotatable sprocket wheel (pulley) on the second joint lower mast top.Be connected with the chain (wire rope) as traction between its second joint and the 4th joint, this chain (wire rope) is walked around the rotatable sprocket wheel (pulley) on the 3rd joint top, and the one end is connected the bottom of the 4th joint lower mast.When making progress jacking, the oil cylinder in second joint upwards hoists by the 3rd joint lower mast of chain (wire rope) traction in the sprocket wheel (pulley) on the second joint top.In like manner, chain (wire rope) traction the 4th joint lower mast in the sprocket wheel (pulley) on the 3rd joint top upwards hoists.By that analogy.
How many flexible up and down total kilometres of mast (being the flexible distance of mast) are realized by each lower mast self length of fit and the joint number of lower mast fit, lower mast self length is relevant to mast fundamental length (promptly can not telescopic section length), what the selection of the joint number of lower mast fit, can determine the size of mast fundamental length, adopt different choice during design, can realize the size of different basic arm length or flexible stroke with the boats and ships conditional request, selected suitable combining form.
Fig. 9, Figure 11 be please continue to consult, can for the guiding that realizes adjacent two lower masts joint is slidingly connected, the lower mast joint holding tank 14 and position-limited edge 15 be provided with along its length direction in conjunction with Fig. 3 simultaneously.Adjacent two lower masts joint is positioned at another holding tank 14 by one of them position-limited edge 15, and this position-limited edge guide runner 21 is housed bottom, in the top of holding tank guide fixed block 23 is housed.
In the present embodiment, described ascending/decending mast is two masts, and every group of lower mast is the lower mast of 2 symmetries.See also Fig. 4, just simply having described every group of lower mast among Fig. 4 is 2, and is symmetrically arranged, and the sectional view of each mast is not as shown in Figure 4, and its sectional view can be with reference to figure 3.
The basic pattern of cresset mast peculiar to vessel is " cross " type (can with reference to figure 5A), but the upper end cross bar of cross often is again a plurality of cross bar type to be arranged, general flexible way just can not continue retraction because of hindered by cross bar when meeting first (lower end) cross bar, the mast that still leaves equivalent length is beyond flexible scope, by " boats and ships Legal Inspection rule " regulation, the spacing of last sheer pole is at least 2 meters (minimum ranges between two range lights), therefore under general flexible way, the upper end rail segment still can not retraction segment section have more than 7 meters, often can not reach complete flexible promising result.
In order to make the rail segment part (upper end) on the mast still can realize vertical flexible, utilize the lower mast structure of " the more piece combining form " of present technique, connect (being generally the welding body) mode with the lower mast body of rod in conjunction with " to right-angled intersection " cross bar and improve, can realize the purpose of " complete flexible ".See also Fig. 5 B-Fig. 5 F, in the utility model, a part is overlapped in a side of corresponding lower mast in the described cross bar, and another part is overlapped in the opposite side of corresponding lower mast; Or described cross bar all is overlapped in a side of corresponding lower mast.Can better reduce height like this.Be overlapped on the front side (left side) of corresponding lower mast as cross bar, the cross bar of even (odd) be overlapped on the rear side (right side) of corresponding lower mast odd (even).
It is complete flexible to divide following two steps to realize:
The utilization of [first step] " more piece lower mast combining form ", it is that the basic body of rod that the section bar of fundamental section promptly is called " lower mast " is formed that flexible mast is flute profile by more piece, existing be example explanation (asking the while referring to Fig. 1, Fig. 3) with " double-mast formula ":
This type is formed with centrosymmetric double joint lower mast, and every double joint lower mast pairing at the same level is united and moved up and down, and about every pair to fit from the inside to the outside, forms the stretching motion (seeing the sectional drawing of Fig. 4) between each joint (lower mast).
Note that each to the fit between lower mast along about form to (see figure 4), their fore-and-aft direction (side) is a free space, it is the fit that do not overlap each other in the telescopic process, therefore can be in the front and back of mast to cross bar be set, make mast in integrated motion, not be subjected to stopping mutually of cross bar and continue retraction.
Utilize this point, just can connect firmly the cross bar of a right-angled intersection on the lower mast of motion under every distich is closed, and realize condensation and stretching, extension between each cross bar simultaneously.
So just can make whole mast section not only realize down half---promptly be commonly called as the condensation of " polished rod section ", and make mast the upper half especially, the cross bar that often must be provided with right-angled intersection can not the retraction section also be realized flexible smoothly, form the globality condensation of mast, promptly novel " flexible full mast ".
[second step] " cross bar connects with the lower mast body of rod " mode is improved:
General not flexible mast connects with cross bar, often get the connecting mode that is commonly called as " fork-join ", the characteristics of this connection are " axis of the two right-angled intersection bodies of rod are in same plane ", but this just tends to cause montant (lower mast) flexiblely is subjected to directly stopping of cross bar volume and can not continues retraction (stretching out), and relatedly has influence on flexible between each cross bar.
Complete flexible mast with adopt two ways of intersecting " body of rod axis is not or not same plane " connecting of cross bar, promptly popular wording is: two crossbars " overlap joint " way, or (back) connection of " putting out " forward of title cross bar, shown in Fig. 5 B-Fig. 5 F.Be that " neck section " of 2-3 millimeter realizes connecting firmly (avoid with stretch up and down respectively save lower mast frame direct friction) by a spacing between two bars overlap joint (intersections).
This way has avoided the intersection cross bar that flexible lower mast is stopped, makes whole mast realize the purpose that rail segment still can be utilized the retraction of multi-joint telescoping lower mast and stretch out.
Realize " complete flexible " of so-called whole mast thus.
The flexible distance of the Lower Half of whole mast " body of rod section " is by what and the decision of lower mast self length of each joint lower mast.Select different joint numbers or length can form the various combination of " body of rod section ", to adapt to the concrete needs of different boats and ships.
Distance between the first half of mast each " right-angled intersection section ", can be by each lower mast length decision its spacing of every joint transposition section, should be by " inspection rule " requirement spacing greater than 2 meters, generally for " tail mast ", the quantum of spreader is 4, but also slightly has any different according to ship kind difference, therefore, be equipped with the joint number and the length of corresponding first cross part lower mast, just can adapt to of the specific requirement of all kinds of different boats and ships mast.
The introduction of several multi-form built mast:
The ascending/decending mast according to the different needs of all kinds of ship kinds, has following three kinds of basic combinations and mounting means when reality is used.
1. whole Zhi Shuzhi mounting means:
The installation of ascending/decending mast on the boats and ships ceiling, a kind of is to take " mast based (root framework) " directly to weld the mode of (Bolt Connection) with ceiling, at this moment the part height after the mast condensation (this height of lower mast segment base), naked on ceiling, have the certain height requirement, general its base altitude of design point is about (this height of lower mast segment base) about 2.5 meters.
" complete flexible " mast, i.e. " vertical mounting means " of having stated clearly above the form that is appropriate to the ascending/decending mast of above-mentioned mounting means is.This mode usually is adapted on the boats and ships of " river and sea ", reason is to navigate by water in much higher because of striding the high canal foot bridge relatively of river bridge bridge as the ship of the Changjiang river trunk airlines, and in fact the boats and ships ceiling still has enough remaining spaces can be by due to the base altitude of putting after the condensation apart from the bridge headway.
The state of this mode when crossing bridges and culverts as shown in Figure 6
2. part bending body of one who has dropped dead by the roadside mounting means
Mounting means and accommodation (description of ship) are as follows:
Adopt upper semisection (part has rail segment) bending body of one who has dropped dead by the roadside, lower semisection (body of rod section of no rail segment) is imbedded the mounting method in the cabin under the ceiling, this mode stay can not retraction upper semisection generally be controlled in the 4-5 rice length range, by bending hinged (or back) forward body of one who has dropped dead by the roadside, shorter because of the body of one who has dropped dead by the roadside section, manpower can easyly be implemented.
The cabin inner segment of imbedding ceiling is the condensation part of elevation mast.
After condensation and example crouch, because condensation portion body of rod height is placed in the cabin, the body of one who has dropped dead by the roadside kink (hinged) together with the body of one who has dropped dead by the roadside after mast (breadth wise dimension) space requirement generally all very little (can be controlled in the 0.3-0.4 rice---as shown in Figure 7), so it can dwindle the setting height(from bottom) after the mast condensation greatly, the boats and ships that are suitable for low bridge headroom yardstick use.
This mode range of application is representative, mainly is suitable in navigating area, tributary, inland river---pass through the marine vessel applications of low bridge in the navigation channel, Grand Canal, routine Hangzhoupro in Beijing,
State is as shown in Figure 7 when crossing bridges and culverts for the flexible mast mode of body of one who has dropped dead by the roadside formula
3. the mounting means of a whole again body of one who has dropped dead by the roadside after the vertical condensation:
Promptly under the condensed state of above-mentioned " whole Zhi Shuzhi mounting means ", after its basal part installation is hinged, realize body of one who has dropped dead by the roadside as shown in Figure 8 again.
Can take manpower formula or mechanical power type method to lie down according to the volume and weight of set mast.
Difference according to Description of Ship, the difference that the navigating area navigation requires, can in above-mentioned several basic mounting meanss, select suitable form, again according to specific requirement such as setting height(from bottom), buried section cardinal scales after mast out to out (stretch height after), range light spacing, the condensation, by changing telescopic topmast column length, joint number, select mast combination or structure citation form.
For the bigger mast of overall height, usually wire rope " dead rope " is set in the hope of firmly in the mast upper end on the ship according to actual conditions.
In sum, the ascending/decending mast that the utility model proposes, vertical can be according to flexible; The utility model is specially adapted to the ships that transport in river and sea or Haihe River through (specially referring to tributary, the network of waterways, coastal through inland river).Along with the development of shipping business, boats and ships navigating area scope is in continuous expansion, and the big-and-middle-sized boats and ships that enter rivers are also apparent more frequent, necessary timely, the appropriate solution of contradiction of conditional bridge height on the requirement that standard is provided with mast and the rivers.The ascending/decending mast that the utility model discloses has solved the navigation problem of limited bridge relative superiority or inferiority simply, easily by its forms such as lower mast condensation, top body of one who has dropped dead by the roadside.
