Detailed description of the invention
Just as described in the background section, as shown in Figure 1, under the prior art, adopt highway 1 and the railway 2 of separate type graded crossing mode, space is there is between top highway multiple line arranged side by side, in daily road construction maintenance process, fall and bring huge potential safety hazard for preventing object to the below vehicles, must properly protect measure.
Because current safeguard procedures mainly utilize baffle plate to be covered in space, but the longer and width of the general distance in space is not etc.; For ensureing construction requirement, usually need with a large amount of baffle plate, space to be blocked, or by part baffle plate with construction speed constantly movement, this brings very big inconvenience to construction.
Based on the basis of above-mentioned research, the utility model provides a kind of bridge span line segment falling proof device, and it mainly blocks space with below with the main body baffle plate 33 of the first roller 35, and wherein, the first roller 35 is close to both sides, space horizontal side; Meanwhile, be also provided with and be close to two side, space, for the second roller 36 that whole device is located.
Main body baffle plate 33 can be promoted so as required move integrally, both reduce the consumption of baffle plate, made again baffle plate move laborsaving; Meanwhile, the second roller 36 makes the steadiness of whole device strengthen, and convenient construction personnel trample.
It is more than the whole description of the technical solution of the utility model, below in conjunction with specific embodiment and accompanying drawing, technical scheme in the utility model embodiment is clearly and completely described, obviously, described embodiment is only a part of preferred embodiment of the present utility model, instead of whole embodiments.Those skilled in the art can when doing similar distortion without prejudice to when the utility model intension, and therefore the utility model is by the restriction of following public specific embodiment.
As shown in Figure 3, described main body baffle plate 33 has more piece, and in specific embodiment, its main body is the rectangular frame adopting section bar to make, and frame roof lays steel plate.Main body baffle plate 33 is articulated and connected each other, and hinged place can be pulled down.Like this, when space occurs certain bending, this device entirety can be carried out certain amplitude according to space trend and be bent, hinged due between realization body baffle plate 33, and those skilled in the art of the present technique are easy to realize, and are not described in detail at this.
Because hinged place exists space, object still has falling risk, therefore, between hinged place two main body baffle plate 33, is provided with removable cover 32, this removable cover 32 can block the space that hinged place is formed, and can also ensure can freely hinged rotation between two main body baffle plates 33.
In specific embodiment, as shown in Figure 3, removable cover 32 one end utilizes hinge to be hinged on main body baffle plate 33 upper surface, side, and its other end is overlapped on opposite side main body baffle plate 33 upper surface naturally like this; When constructing, cover plate being put down, after construction, cover plate being started, taking jointed shaft apart, by each main body baffle plate 33 separately, thus be convenient to transport.
For the setting of the first roller 35, in specific embodiment, as shown in Figure 4, main body baffle plate 33 lower surface is vertically installed with fixed mount 34, this fixed mount 34 has two groups totally four, often group two of being arranged symmetrically with for horizontal direction, and be provided with a rotating shaft 341 between often organize two fixed mounts, rotating shaft 341 two ends are respectively equipped with the first roller 35 of a horizontal arrangement.
Main body baffle plate 33 is being put into gap, and the first roller 35 is adjacent to road surface, two ends, gap, and promotion main body baffle plate 33 can be needed to move integrally according to construction.
In specific embodiment, the first roller 35 is directional wheel or the universal wheel of strap brake, like this, can be braked locked fixing, improve steadiness when Specific construction.
In addition, because gap length differs, for ensureing the resistance to overturning of the utility model in pushing course, as shown in Figure 4, slide bar 342 is provided with below fixed mount 34, described slide bar 342 to be positioned at below rotating shaft 341 and to be equipped with helical spring 3421, and described slide bar 342 tail end is provided with second roller 36 longitudinally arranged.Known, in progradation, the second roller 36 can adjustable range automatically, all the time with two side, space close contact, thus ensures the steadiness in progradation.
Special instruction, slide bar 342 profile is polygon or regular polygon, preferred rectangle or square in specific embodiment, it coordinates with the corresponding polygonal hole on fixed mount 34, thus ensure that slide bar 342 can only fixed mount 34 horizontal slip relatively, and can not rotate, thus ensure overall steadiness.Certainly, slide bar 342 profile can be also other non-circular shape, as long as can ensure that its not relative fixed mount 34 rotates.
Improve as one, main body baffle plate 33 upper surface can also be provided with instrument cases, and these instrument cases are rectangle or infundibulate body structure, can certainly be arranged to other shapes, is mainly used to the instrument or the object that hold use in road construction maintenance.
Except the technical characteristic described in manual, be the known technology of those skilled in the art.
The above has made detailed description to preferred embodiment of the present utility model and embodiment by reference to the accompanying drawings; but the utility model is not limited to the above-described embodiment and examples; for those skilled in the art; without departing from the concept of the premise utility; can also make some improvement and modification, these improve and modification also should be considered as protection domain of the present utility model.
