Abstract
The utility model discloses a kind of railroad track confining bed concrete screeds, the second telescopic rod including being fixedly connected on crossbeam both ends, it is characterized by: being provided with the first telescopic rod being fixedly connected on crossbeam between second telescopic rod, first telescopic rod slidably connects the first rod piece, second telescopic rod slidably connects the second rod piece, the bottom of first rod piece is rotatably connected to the screed to adjust leveling angle by rotating member, vibrator is installed on the screed, the both sides of the edge position of the screed is horizontally installed with the second idler wheel for limit.The utility model is by vibrator and can be rotated the screed of certain angle to the progress height leveling of concrete enclosing layer surface, angle adjustable is flattened simultaneously, so that the drainage effect in draining face is significantly improved, while this kind of device is easy to operate, operation number is few, greatly reduces labor intensity.
Description
Technical field
The utility model relates to concrete screed technical field, specially a kind of railroad track closing layer concrete leveling
Machine.
Background technique
With the development and construction of high-speed railway cause, concrete enclosing layer is considered as high-speed rail roadbed and bridge floor guarded drainage
Key structure, surface smoothness, weathering ratio of slope directly affect the impression quality of drainage effect and engineering, confining bed cross section
For " V " type weathering, vertical section face determines drainage direction according to route longitudinal slope.
Currently, mostly using concrete tamping stick to vibrate in construction, surface artificial receipts light, since volume of concrete is small, surface
Product is big, and quality of vibrating is uncontrollable, and artificial light efficiency of receiving is low, and concrete surface is easily caused to crack and at high cost.
Utility model content
The purpose of this utility model is to provide a kind of railroad track confining bed concrete screeds, to solve above-mentioned background
The problem of being proposed in technology.
To achieve the above object, the utility model provides the following technical solutions: a kind of railroad track closing layer concrete is whole
Flat machine, the second telescopic rod including being fixedly connected on crossbeam both ends, it is characterised in that: be provided between second telescopic rod solid
Surely the first telescopic rod being connected on crossbeam, first telescopic rod slidably connect the first rod piece, and second telescopic rod is sliding
Dynamic to be connected with the second rod piece, the bottom of first rod piece is rotatably connected to the leveling to adjust leveling angle by rotating member
Plate is equipped with vibrator on the screed, and the both sides of the edge position of the screed is horizontally installed with second for limit
Idler wheel.
The screed is set as " V " font, and is equipped with the concentric shafts for rotational angle in the bottom of central axes, and
Rotational angle is 0 ° to 30 °.
First telescopic rod and the first rod piece and the second telescopic rod and the second rod piece pass through lifting rocking bar sliding and connect
It connects.
The bottom of second rod piece is equipped with the first idler wheel.
Traction hook is installed on the screed.
As shown from the above technical solution, the utility model by vibrator and can be rotated the screed of certain angle to coagulation
Grave closes layer surface and carries out height leveling, while flattening angle adjustable, so that the drainage effect in draining face is significantly improved,
This kind of device is easy to operate simultaneously, and operation number is few, greatly reduces labor intensity.
Detailed description of the invention
FIG. 1 is a schematic structural view of the utility model.
In figure: 1 crossbeam, 2 first rod pieces, 3 first telescopic rods, 4 lifting rocking bars, 5 second telescopic rods, 6 second rod pieces, 7 the
One idler wheel, 8 vibrators, 9 mounting tables, 10 concentric shafts, 11 screeds, 12 traction hooks, 13 rotating members, 14 second idler wheels.
Specific embodiment
The utility model is described further with reference to the accompanying drawing:
A kind of railroad track confining bed concrete screed as shown in Figure 1 is equipped in front of device when arranging tooling
Hoist engine to connect traction hook 12 by wirerope, and provides tractive force for whole device, the first idler wheel 7 is placed in
On the supporting layer of construction, screed 11 is placed in concrete layer to be flattened, while being made by bar shaped bolt and being bolted
It obtains the second idler wheel 14 and realizes width adjusting, and connect with the edge vertical scrolling of supporting layer, with realization device in width side
To position-limiting action, during the motion, vibrator 8 vibrates, and drives screed 11, make its under the traction of hoist engine along
Concrete layer to be flattened is laid with direction movement.
A kind of railroad track confining bed concrete screed is fixedly connected with the second telescopic rod 5 at the both ends of crossbeam 1, described
The first telescopic rod 3 being fixedly connected on crossbeam 1, first telescopic rod 3 and the first rod piece are provided between second telescopic rod 5
2 and second telescopic rod 5 and the second rod piece 6 be slidably connected by going up and down rocking bar 4, the present embodiment is controlled using lifting rocking bar 4
The relative position of rod piece and telescopic rod, to realize that rod piece adapts to different ground levels and to the position of screeding concrete layer height
It sets adjustable；First telescopic rod 3 slidably connects the first rod piece 2, and second telescopic rod 5 slidably connects the second rod piece 6,
The bottom of second rod piece 6 is equipped with the first idler wheel 7, and the bottom of first rod piece 2 is rotatably connected to by rotating member 13
To adjust the screed 11 of leveling angle, traction hook 12, to connect with hoist engine, institute are installed on the screed 11
It states screed 11 and is set as " V " font, and the concentric shafts 10 for rotational angle, and angle of rotation are installed in the bottom of central axes
Degree is 0 ° to 30 °, by adjusting the angle of screed 11, so that leveling precision is higher, improves the scope of application of this tooling；It is described
Vibrator 8 is installed, the bottom of the vibrator 8 is connect by mounting table 9 with screed 11, the leveling on screed 11
The both sides of the edge position of plate 11 is horizontally installed with the second idler wheel 14 for limit,
Embodiment described above is only that preferred embodiments of the present invention are described, not practical to this
Novel range is defined, and under the premise of not departing from the spirit of the design of the utility model, those of ordinary skill in the art are to this
The various changes and improvements that the technical solution of utility model is made should all fall into the protection that the utility model claims book determines
In range.
