The phenomenon that shaking.
Embodiment 2
The present embodiment on the basis of embodiment 1, for the stability for further increasing evacuation platform, to support platform plate 2
Support frame 1 improved.
As shown in Fig. 1~5 and Fig. 9, the crossbeam 11 includes main body of cross-beam 111 and 111 both ends of main body of cross-beam is arranged in
First protrusion 112, the first protrusion 112 upwardly extend, and platform board 2 is mounted on main body of cross-beam 111, first protrusion 112
Setting effectively prevent the double swerve on support frame 1 of platform board 2, and there is certain limit to guide the installation of platform board 2
Effect occurs horizontally slipping for opposite support frame after preventing 2 stress of platform board, improves the stability on 2 left and right directions of platform board.
Further, the second protrusion 113 is additionally provided on main body of cross-beam 111, second protrusion 113 is set as more
A, when platform board 2 is mounted on support frame 1, the second protrusion 113 is connected in the grid gap of platform board 2, is put down for preventing
Platen 2 slides back and forth, and improves the stability of platform board 2 in the longitudinal direction.It is convex from there through the first protrusion 112 and second
The synergistic effect for playing 113 prevents platform board 2 that the opposite sliding of front and rear, left and right occurs, improves the stability of platform board, avoid
Passenger by when occur acutely shake, further increase the security and stability of evacuation platform.
Support frame 1 further includes having the first support plate 17 and the second support plate 18, the first support plate 17 and the second support plate 18
It is coplanar with crossbeam 11, and one end of the first support plate 17 and the second support plate 18 is connected to first protrusion of 11 one end of crossbeam
On 112 two sides, the other end of the first support plate 17 and the second support plate 18 can be directly anchored in tunnel wall, so that
First support plate 17, the second support plate 18, crossbeam 11 are formed as the joint face of triangle with tunnel wall respectively, increase support frame
1 stability of strutting system.On the other hand, two support plates are coplanar with crossbeam 11, share the part gravity of platform board, are mitigated flat
Platen 2 improves the service life of the even entire support frame 1 of crossbeam to the pressure of crossbeam 11.What guarantee supported about 2 platform board
There is the phenomenon that part tilts after preventing platform board 2 to be placed on support frame 1 in stationarity.
Evacuation platform provided in this embodiment ensure that platform by the setting of crossbeam and its first protrusion, the second protrusion
Stability around plate on direction, when preventing passenger by platform board 2, the phase on the direction of front and rear, left and right occurs for platform board
To sliding, increase the stability of platform board.The setting of first support plate and the second support plate, so that the first support plate 17, second
Support plate 18, crossbeam 11 form stable triangular structure with tunnel wall respectively, and can share the part gravity of platform board, subtract
Light platform board improves the overall stability of evacuation platform to the pressure of crossbeam.
Embodiment 3
The present embodiment, for the stability for further increasing evacuation platform, provides a kind of evacuation on the basis of embodiment 2
The platform board structure of platform.
As shown in Fig. 1~3 and Fig. 6~7, the platform board 2 is set as frame-like structures, specifically includes integrally formed frame
Body 21 and grid portion 22, the framework 21 are set as rectangle structure, and rectangular side length can be according to the size of tunnel space
And the distance between two adjacent supports framves reasonably adjust, use scope is extensive and facilitates processing.The grid portion 22 is arranged
For the formation arranged in parallel of multiple grille strips 221, when platform 2 is mounted on support frame 1, grille strip 221 is parallel to support frame 1
Crossbeam.The weight of platform board is reduced, material is saved.
Specifically, the grille strip 221 includes flat part 222, the first hang plate 223 and the second hang plate 224, it is adjacent
Two grille strips 221 between there are gaps.Further, flat part 222 is set as the structure concordant with 21 upper surface of framework,
First hang plate 223 and the second hang plate 224 are connected to the two sides of flat part 222.Specifically, first hang plate
223 are connected to the side on flat part 222 close to tunnel wall, and the first hang plate 223 tilts down extension, second inclination
Plate 224 is connected to the side on flat part 222 far from tunnel wall, and the second hang plate 224 also tilts down extension, and described second inclines
The length of inclined plate 224 is greater than the length of the first hang plate 223.
Further, a part of 221 second hang plate 224 of the first hang plate 223 covering front side adjacent grid item, and the
There are certain gaps between the second hang plate 224 on one hang plate 223 and front side adjacent grid item 221, when the shoes of passenger
When between the flat part 222 with stretching to two grille strips 221, the first hang plate 223 and the second hang plate 224 have heel
Certain supporting role, and prevent heel from falling into gap.Therefore, it is enough not only to guarantee that platform board has for the setting in grid portion
Wind pressure, and gap will not snap into the heel of passenger, guarantee passenger by when safety.
Further, when platform board 2 to be installed on support frame 1, the second protrusion 113 on crossbeam 11 is connected to grid
In portion 22.Specifically, second protrusion 113 include the first convex block 1131a, the second convex block 1131b and be located at the two
Between gap 1132, the first convex block 1131a and the second convex block 1131b are respectively protruding into two adjacent second hang plates 224
Portion, gap 1132 between the two are used to accommodate the lower end of the second hang plate 224, and the first convex block 1131a and the second convex block
The medial surface of 1131b is disposed as inclined-plane, so that matching with the gradient of the second hang plate 224, so that on crossbeam
Two raised 113 pairs of grille strips 221 play certain limit fixed function, and platform board is prevented to be moved forward and backward.
Preferably, the platform board in the present embodiment is compounded to form compound using phenolic resin and continuous fiber reinforcement material
Material, by adjusting the type, dosage and laying form of continuous reinforcing fiber to obtain ideal mechanical property.More preferably
, the continuous reinforcing fiber uses inorfil, such as selection glass fibre, carbon fiber, one of silicon carbide fibre or
It is a variety of.Preferably, the formula of the composite material is using as shown in table 1:
1 composite-material formula of table
The selection of above-mentioned material can not only reduce the calorific value of platform board, improve the flame retardant property of material, and inorganic fibre
Dimension has enough intensity, corrosion resistance and heat resistance, it is ensured that composite material evacuation platform security performance is higher.
Evacuation platform platform board structure provided in this embodiment is matched with the support frame of platform board lower part, effectively prevent putting down
Platen slides, and the setting of platform board can not only guarantee that platform board has enough wind pressure, and gap will not snap into
The heel of passenger, guarantee passenger by when safety, improve product competitiveness.
Embodiment 4
As shown in figure 1-9, a kind of evacuation platform, including support frame 1 and platform board 2, the support are present embodiments provided
Frame 1 includes load-bearing part 12, crossbeam 11 and cable bearer 15.
The load-bearing part 12 includes substrate 16 and the side baffle 14 that 16 two sides of substrate are arranged in, and the outer edge of substrate 16 is set
It is set to arc, so that matching when its installation with tunnel wall, facilitates installation.The sky that substrate 16 and its side baffle of two sides 14 surround
