The utility model is used for road construction draws binding books without trimming to put with concrete.

Description

Concrete draws binding books without trimming to put for road construction

The technical field is as follows:

the utility model relates to a road construction is with concrete napping device.

Background art:

the method is characterized in that the concrete is napped frequently in the road construction process, at present, small construction is carried out through napping rakes, a bottom plate is firstly arranged to limit the pulling track of the napping rakes to prevent deviation, then rake teeth pull out pull grooves on the concrete, at present, the napping rakes need to stand on two sides of the concrete road for a long time, then one person lifts the napping rakes and holds one end of the napping rakes, the other end of the napping rakes is lifted to another person on the concrete road surface to be connected with the other person, and then the napping rakes are placed on the concrete road.

The utility model has the following contents:

the utility model aims at providing a road construction is with concrete napping device.

The above purpose is realized by the following technical scheme:

the utility model provides a road construction is with concrete napping device, its constitution includes: the novel scraper conveyer comprises a base plate, two parallel slide bars arranged in parallel are welded on the base plate, a slide block is sleeved on the slide bars and can slide on the slide bars, the right side of the slide block is connected with a rotating plate through a rotating shaft, two telescopic sleeves are arranged at the bottom of the rotating plate and fixed on a fixed plate, a group of uniformly arranged rake teeth are welded on the fixed plate in a ground step mode, and the rake teeth are perpendicular to the fixed plate.

The concrete roughening device for road construction has fixed pipe welded to the top of the rotating plate, harrow bar inserted into the fixed pipe and connected to the harrow bar via screws, and the length of the harrow bar is equal to that of the bottom plate.

Has the advantages that:

1. the utility model discloses can slide with the fixed plate rake teeth in addition, do not need operating personnel to lift the napping harrow, also guarantee simultaneously when the motion that the fixed plate is parallel with the bottom plate always, guarantee the orbit of napping.

The utility model discloses can use manpower sparingly, only need just can accomplish whole napping process alone, the napping is efficient simultaneously.

Description of the drawings:

fig. 1 is a top view of the present invention;

FIG. 2 is a cross-sectional view taken along line A-A of FIG. 1;

FIG. 3 is an enlarged view of portion B of FIG. 1;

in the figure: 1. a slide bar; 2. a base plate; 3. a slider; 4. a rotating plate; 5. a rotating shaft; 6. a harrow bar; 7. a fixing plate; 8. rake teeth; 9. a telescopic sleeve; 10. and fixing the tube.

The specific implementation mode is as follows:

example 1:

the utility model provides a road construction is with concrete napping device, its constitution includes: the bottom plate 2, the bottom plate on weld two parallel slide bars 1 that set up side by side, slider 3 cover the slide bar on and can the slide bar on slide, the slider right side be connected through pivot 5 with rotor plate 4, the pivot pass the round hole on the rotor plate and with round hole clearance fit, the both ends welding of pivot is at the slider right-hand member for the rotor plate can use the pivot to rotate as the center, the bottom of rotor plate set up two telescopic tube 9, telescopic tube fix on fixed plate 7, the ground step welding of fixed plate by a set of rake teeth 8 that evenly set up, the rake teeth with the fixed plate mutually perpendicular.

Example 2:

according to the concrete roughening device for road construction of embodiment 1, the top of the rotating plate is welded with a fixed pipe 10, a harrow bar 6 is inserted into the fixed pipe and is connected with the harrow bar through a screw, and the length of the harrow bar is equal to that of the bottom plate.

When the scraper blade is used, as shown in fig. 1, the fixed plate and the rotating plate are located below the bottom plate, an operator holds the scraper rod to enable the rotating plate to rotate, the rotating plate rotates anticlockwise as shown in fig. 2, the right end of the rotating plate is lifted, then the outer tube of the telescopic tube slides, the exposed length of the inner tube is minimum, the scraper rod is held to push the scraper rod to enable the sliding block to slide upwards along the sliding rod, the rotating plate rotates reversely after sliding to the upper side, the fixed plate moves downwards under the action of self gravity after rotating to the horizontal position, the lower portion of the scraper tooth is inserted into concrete, then the scraper rod is pulled to be brushed, the sliding block slides on the sliding rod all the time in the brushing process, the fixed plate can be guaranteed to be always parallel to the bottom plate, and after brushing is finished, the bottom plate is lifted to the next position to be brushed.

Claims (2)

1. The utility model provides a road construction is with concrete napping device, its constitution includes: the bottom plate, characterized by: the novel rake is characterized in that two parallel sliding rods are welded on the bottom plate, the sliding rods are sleeved with the sliding blocks and can slide on the sliding rods, the right sides of the sliding blocks are connected with the rotating plate through rotating shafts, two telescopic sleeves are arranged at the bottom of the rotating plate and fixed on a fixed plate, a group of uniformly arranged rake teeth are welded on the fixed plate in a step mode, and the rake teeth are perpendicular to the fixed plate.

2. A concrete roughening apparatus for road construction according to claim 1, wherein: the top of the rotating plate is welded with a fixed pipe, a harrow bar is inserted into the fixed pipe and is connected with the harrow bar through a screw, and the length of the harrow bar is equal to that of the bottom plate.
