Summary of the invention
For the problems referred to above, the purpose of this utility model is to provide a kind of railway freight-car curb girder technique simple in structure, that be convenient to installing/dismounting and supports.
For achieving the above object, the utility model is taked following technical scheme: a kind of railway freight-car curb girder technique support, it is characterized in that: it comprises a double end adjusting bolt, the middle part of described double end adjusting bolt is a square column, wherein be provided with one for plugging the through hole of spanner in a center, side in described square column, the helical axis rotation direction that described double end adjusting bolt two is stretched out is contrary each other trapezoidal thread; On the helical axis that described double end adjusting bolt two is stretched out respectively corresponding the screw-in a square lining is arranged, the outer end of each described square lining is the corresponding crossbeam that is inserted with a rectangular tube respectively, far-end at each described crossbeam is fixedly connected with respectively a C type card orchid, be fixedly connected with respectively an adapter sleeve with internal thread on the inner port of each described C type card orchid, screw in respectively in each described adapter sleeve and have one for the blue bolt that compresses curb girder of described C type card.
The middle part cylinder machining shape of described double end adjusting bolt is a kind of in triangle, square, circular, hexagon, polygon.
Described crossbeam adopts a kind of processing and fabricating in rectangular steel pipe, round steel pipe, channel-section steel section bar.
Described at each, the afterbody of bolt compresses end and is respectively arranged with the protruding dish contacted with supporting surface for increase accordingly.
The utility model is owing to taking above technical scheme, and it has the following advantages: 1, the utility model, owing to adopting C type card orchid to be fixedly connected with curb girder, therefore makes it simple in structure, and installation and disassembling section are all very convenient.2, the utility model due to adopt stud that rotation direction is contrary respectively spiral connect each square lining, the support elasticity of adjusting process support, therefore make support operation flexibly laborsaving, make assembly working efficiency high.3, the utility model, because adopting process support support curb girder can realize regulating installation and dismounting, has therefore been saved the production input cost, effectively guarantees that curb girder is not by cut wound.The utility model is used among can being widely used in various machine-building supports.
The accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is double end adjusting bolt of the present utility model and square lining connection diagram;
Fig. 3 is the utility model working state schematic representation.
The specific embodiment
Below in conjunction with drawings and Examples, the utility model is described in detail.
As shown in Figure 1 and Figure 2, the utility model comprises a double end adjusting bolt 1, the middle part of double end adjusting bolt 1 is a square column, wherein be provided with a through hole 2 for plugging spanner in a center, side in square column, 1 liang of helical axis stretched out of double end adjusting bolt, 3,4 rotation directions are contrary each other trapezoidal thread.On 1 liang of helical axis stretched out of double end adjusting bolt 3,4, corresponding the screw-in has a square lining 5,6 respectively, the outer end of each square lining 5,6 is the corresponding crossbeam 7 that is inserted with a rectangular tube respectively, far-end at each crossbeam 7 is fixedly connected with respectively a C type card orchid 8, be fixedly connected with respectively an adapter sleeve 9 with internal thread on the inner port of each C type card orchid 8, screw in respectively in each adapter sleeve 9 and have one for C type card blue 8, to compress the bolt 10 of curb girders.
In above-described embodiment, the middle part cylinder machining shape of double end adjusting bolt 1 is a kind of in triangle, square, circular, hexagon, polygon.
In above-described embodiment, a kind of processing and fabricating that crossbeam 7 adopts in the section bars such as rectangular steel pipe, round steel pipe, channel-section steel.
In above-described embodiment, in order increasing and the contacting of supporting surface, to compress end at the afterbody of each bolt 10 and be provided with corresponding difform protruding dish 11.
As shown in Figure 3, the utility model supports while using:
1) operator manually or insert spanner rotation double end adjusting bolt 1, make the helical axis 3,4 that two of double end adjusting bolt 1 is stretched out screw or screw out in two square linings 5,6 respectively, make the two C type card orchids 8 that are connected to two crossbeam 7 far-ends stretch out and lean or inwardly draw by curb girder 12 to far-end.
2) craft or spanner screw bolt 10, make C type card orchid 8 be adjacent to closely curb girder 12, complete and support and the fixedly operation of curb girder.
During the utility model dismounting:
1) craft or spanner counter-rotate respectively the bolt 10 unclamped on each C type card orchid 8, and the protruding dish 11 of bolt 10 front end is separated with curb girder 12;
2) operator manually or spanner rotation double end adjusting bolt 1, the C type card blue 8 that two square linings 5,6 is connected respectively by rotation by each crossbeam 7 increases or shortens distance each other, makes C type card orchid 8 away from curb girder;
3) manually praise and unload technique support of the present utility model, complete disassembling section.
The various embodiments described above are only for illustrating the utility model; wherein the structure of each parts, connected mode etc. all can change to some extent; every equivalents of carrying out on the basis of technical solutions of the utility model and improvement, all should not get rid of outside protection domain of the present utility model.
