Description
Technical field
The present invention relates to gaseous propellant engine field, external series gap supporting support in particularly a kind of both arms pipe.
Background technology
Leakage hidden danger, therefore the supply pipe of gaseous fuel in use be present in the gaseous fuel in dual fuel engine
Road uses the double-wall pipe with double-decker, even if the gaseous fuel in inner tube is leaked, can also enter double-wall pipe
, so can be double to ensure to force to extract out by this portion gas fuel using ventilation blower in interlayer between inner tube and outer tube
Engine fuel fuel it is safe to use.In traditional double-walled tubular construction, relied primarily between inner and outer pipes and be inserted in the two gap
In lip block or spring bearing prop up, in this traditional structure, it is easy to because installation site is deposited between inner tube and outer tube
Cause the problems such as eccentric wear, air permeability are poor, maintenance is complicated occur in deviation.
The content of the invention
The present invention is to solve the above-mentioned deficiency present in prior art, proposes a kind of simple in construction, ingenious in design, cloth
Office rationally, can prevent from occurring between inner tube and outer tube eccentric wear, it is local stuffy the problems such as both arms pipe in external series gap supporting support.
The present invention technical solution be：External series gap supporting support in a kind of both arms pipe, it is characterised in that：Described branch
Frame includes toroidal frame 1, left support plate 2 and right support plate 3 is symmetrically provided with the excircle of toroidal frame 1, in left support plate 2
Upper to be connected with upper half round frame 5 by bolt 4, the upper half round frame 5 includes the connecting plate 6 to match with left support plate 2 and upper arc
Plate 7, and lower half round frame 8 is connected with by bolt 4 in right support plate 3, the lower half round frame 8 includes matching with right support plate 3
Connecting plate 6 and arc lower plate 9, and offered on described connecting plate 6 with bolt 4 match elongated hole, in the toroidal frame 1
Inwall and upper arc 7, arc lower plate 9 outer wall on be provided with multiple damping block groups 10, and described damping block group 10 is in circle
It is uniformly distributed in circumferential direction, each damping block group 10 is made up of the 3-6 damping blocks 11 for being parallel to each other and being equally spaced.
The present invention compared with the existing technology, has the following advantages that：
External series gap supporting support in the both arms pipe of this kind of structure type, its is simple in construction, ingenious in design, rationally distributed, and it is directed to
The problem that traditional double wall ligament supporting construction is in practical work process, designs a kind of inside support ring and fix, outside
The adjustable structure of support ring, and inside, outer support ring be also provided with multigroup damping block group with the part that body directly contacts,
By to form outer support ring two and half round frames adjustment, come ensure to have at any time sufficient amount of damping block group with
Outer tube contacts, and so as to realize the excellent support for outer tube, prevents in engine operation process, inner and outer pipes caused by pipeline vibration
Concentricity is deteriorated, and contact point occurs and caused abrasion between outer tube and inner tube, while can also ensure to leave foot therebetween
The gap of amount, so as to avoid the air permeability difference caused by pumping the problem of.And the manufacture craft of this supporting support is simple,
Manufacturing cost is cheap, it can be said that it possesses a variety of advantages, particularly suitable for popularization and application in the art, before its market
Scape is very wide.
Brief description of the drawings
Fig. 1 is the front view of the embodiment of the present invention.
Fig. 2 is the top view of the embodiment of the present invention.
Embodiment
Below in conjunction with the embodiment of the brief description of the drawings present invention.As shown in Figure 1 and Figure 2：Outer room in a kind of both arms pipe
Gap supporting support, it includes a toroidal frame 1, left support plate 2 and the right side is symmetrically provided with the excircle of this toroidal frame 1
Supporting plate 3, upper half round frame 5 is connected with by bolt 4 in left support plate 2, this upper half round frame 5 includes and the phase of left support plate 2
The connecting plate 6 and upper arc 7 matched somebody with somebody, lower half round frame 8 is connected with right support plate 3 also by bolt 4, this lower half round frame 8
Including the connecting plate 6 and arc lower plate 9 to match with right support plate 3, the length to match with the bolt 4 is offered on connecting plate 6
Hole, multiple damping block groups 10 are provided with the inwall of toroidal frame 1, and these damping block groups 10 are uniformly divided in a circumferential direction
Cloth, multiple damping block groups 10 are also equipped with the outer wall of upper arc 7 and arc lower plate 9, these damping block groups 10 are in upper arc
Even circumferential distribution on circle where shape plate 7 and arc lower plate 9 are common, damping block group 10 here are all parallel to each other by 3-6
And the damping block 11 being equally spaced forms.
The course of work of external series gap supporting support is as follows in the both arms pipe of the embodiment of the present invention：By inner tube set in toroidal frame 1
Inner periphery in, allow the outer wall of inner tube to be contacted with multiple damping block groups 10 on toroidal frame 1, by outer tube sleeve in the He of upper half round frame 5
Outside lower half round frame 8, the inwall of outer tube is allowed to be contacted with multiple damping block groups 10 on upper arc 7 and arc lower plate 9, due to this branch
Support support can form the structure of similar two concentric circles in the operating condition, thus can the one side present apparatus can be by double-wall pipe
Inner and outer tubes support, while can also allow and form uniform, stable gap therebetween；If the length of double-wall pipe
It is longer, then multiple this supporting support being equally spaced can be set on the length direction of double-wall pipe；
The diameter of the toroidal frame 1 is fixed, and the state that the outer support being made up of upper half round frame 5 and lower half round frame 8 is justified
It is then adjustable, if it find that deviation is larger between the center of circle of outer tube and the inner tube center of circle, due to being opened up on each connecting plate 6
There is elongated hole, therefore user can be by changing connecting plate 6 and left support plate 2 or the side of the fixed position relative of right support plate 3
Formula, to change the relative position between upper half round frame 5 and lower half round frame 8 and toroidal frame 1, adjustment through the above way, ensure
Have at least that 80% quantity damping block group 10 can contact with the inwall of outer tube at any time, the purpose for the arrangement is that allowing outer tube
It can fully be propped up, prevented in engine operation process, inner and outer pipes concentricity caused by pipeline vibration is deteriorated, outer tube and inner tube
Between there is contact point and caused abrasion, while can also ensure to leave enough gaps therebetween, so as to avoid taking out
Caused by gas the problem of air permeability difference.
