Fig. 1 is the schematic cross-section of traditional railway ladder beam;
Fig. 2 is middle low speed magnetic suspension track two-wire beam section schematic diagram;
Fig. 3 is the schematic perspective view of a kind of embodiment of the utility model;
Fig. 4 is the schematic cross-section of a kind of embodiment of the utility model.
Detailed description of the invention
Technical scheme in the application is understood better in order to make those skilled in the art person, below in conjunction with the accompanying drawing in the embodiment of the present application, technical scheme in the embodiment of the present application is clearly and completely described, obviously, described embodiment is only some embodiments of the present application, instead of whole embodiments.
Fig. 3 shows the schematic perspective view of a kind of embodiment of the utility model, this security platform comprises the levelling bench and protector of constructing for workman, described levelling bench is fixedly installed on the two-wire beam of magnetic-levitation, described two-wire beam 1 is made up of two parallel the first support rail beam 1-1 and the first support rail beam 1-2, comprise the levelling bench for workman's construction and protector, described levelling bench to be arranged on the first support rail beam 1-1 and the first support rail beam 1-2 and from two support rail beam 1-1, the outside of 1-2 is stretched out, described protector is vertically arranged on the end that described levelling bench stretches out the part outside two support rail beams.Levelling bench can be too narrow at support rail beam, cannot for workman construction the environment of working space is provided under, the platform of stand for workman provides, constructing, protector can prevent workman from falling from security platform.
In the present embodiment, described levelling bench comprises load-bearing girder steel 2-1, steel mesh reinforcement 2-2 and bearing plate 2-3, described load-bearing girder steel 2-1 is perpendicular to two support rail beams, load-bearing girder steel 2-1 interval is arranged between the track preset on support rail beam, and stretch out outside described two support rail beams, described steel mesh reinforcement 2-2 is laid on described load-bearing girder steel 2-1 and stretches out part between part outside two support rail beams and two support rail beams, described bearing plate 2-3 is laid on described steel mesh reinforcement 2-2, and described bearing plate 2-3 includes but not limited to plank, wood particle board, plastic plate.
It should be noted that, as shown in Figure 2, F shape rail 7 is fixed on steel tie 6, F shape rail 7 and steel tie 6 together constitute the section of track, the sequence of construction of magnetic-levitation is: by clamping tooling, the section of track is adjusted to precalculated position in advance, then below sleeper, pours into a mould track 8, after track 8 solidifies, remove clamping tooling, finally born the weight of the described section of track by the track 8 cast on support rail beam.Because the load-bearing girder steel 2-1 of track 8 and security platform is arranged on support rail beam, therefore, when setting up the two-wire safety beam platform in the utility model, spaced load-bearing girder steel 2-1 needs the preset avoiding track 8.
As shown in Figure 3 and Figure 4, the protector in the present embodiment comprises vertical rack 3-1 and safety net 3-2, and vertical rack 3-1 is fixed on the two ends of load-bearing girder steel 2-1, and safety net 3-2 is fixed on vertical rack 3-1.Fixed form between vertical rack 3-1 and heavy girder steel can be welded and fixed, and also can be that bolt is fixed.
The present embodiment can also improve as follows:
Because the spacing of the first support rail beam 1-1 and the first support rail beam 1-2 is larger, in order to reduce the length of load-bearing girder steel 2-1, more convenient to install and dismounting, described load-bearing girder steel 2-1 comprises a first spandrel girder 2-11 and two the second spandrel girder 2-12, described first spandrel girder 2-11 is arranged between two support rail beams, two described second spandrel girder 2-12 are separately positioned on described first support rail beam 1-1 and the first support rail beam 1-2, and stretch out from the outside of the first support rail beam 1-1 and the first support rail beam 1-2 respectively, be bolted between described first spandrel girder 2-11 and the second spandrel girder 2-12.
Topple over to prevent security platform from bearing a heavy burden excessive due to side, the part that described first spandrel girder 2-11 contacts with the inner side of described first support rail beam 1-1 and the first support rail beam 1-2 is provided with two vertical fixed bar 2-4, and described fixed bar 2-4 is close to the inner side of the first support rail beam 1-1 and the first support rail beam 1-2.Once security platform due to side bear a heavy burden excessive topple over dangerous, the two fixed bar 2-4 be stuck between the first, first support rail beam 1-2 can provide support, and play a protective role.
In order to strengthen the reliability of protector, described vertical rack 3-1 is also fixed with the horizontal stand 3-3 being no less than connecting spaced vertical rack 3-1, and safety net 3-2 is fixed on vertical rack 3-1 and horizontal stand 3-3 simultaneously.
For the ease of installation and removal, and the floor space reduced after the utility model dismounting is conveniently reused simultaneously, fixed by pedestal steel pipe 3-4 between vertical rack 3-1 and load-bearing girder steel 2-1, described pedestal steel pipe 3-4 is welded on the two ends of described load-bearing girder steel 2-1, described vertical rack 3-1 inserts in pedestal steel pipe 3-4, during dismounting security platform, vertical rack 3-1 is directly extracted out from pedestal steel pipe 3-4.Adopt detachable mode between vertical rack 3-1 and load-bearing girder steel 2-1, can Fast Installation and dismounting be carried out.
The above is only the detailed description of the invention of the application, it should be pointed out that for those skilled in the art, and that makes under the prerequisite not departing from the application's principle the improvement of creative work need not all be considered as the protection domain that the application protects.
