At present, with the continuous development of urban roads in China, the increase of urban traffic flow and the increase of heavy load vehicles, the requirement on road construction quality is more and more strict. Compared with highways and expressways, the urban road is mainly characterized in that various underground pipelines are matched in the urban road, most of the driving lanes are provided with rainwater collecting wells, and most rainwater well covers are in a steel grating rainwater grate form.

The rainwater grate is formed by welding flat steel and twisted square steel or flat steel and flat steel. The rainwater grate has the advantages of beautiful appearance, optimal drainage, high strength, various specifications, low cost and the like. The steel grating is a water-collecting well cover material gradually popularized in municipal facilities. Due to the characteristics of high strength, easy processing and the like of the steel, corresponding load products can be produced according to the requirements of different roads, the maximization of the cross section can also be realized, and the appearance and the long-term use requirement can also be ensured by hot-dip galvanizing treatment.

Most of traditional rainwater grates are installed by a pre-embedded steel bar method, vertical steel bars are pre-embedded in a rainwater well cover plate, a wedge is used for temporary fixation after the rainwater grate is positioned and measured, and the rainwater grate and the vertical steel bars pre-embedded in the rainwater well cover plate are connected and fixed through the steel bars. Because road engineering has longitudinal slope and cross slope, the height of four angles of well grate needs the road slope to keep unanimous, so need repeatedly measure, adjust wedge height and position, and the accuracy is low moreover, and welding process and very easily warp, causes the rainwater grate to fix a position inaccurate, and the axis deviation is big, and the elevation error is big. The rainwater grate is rolled for a long time by vehicles, so that the rainwater grate is damaged or subsided, asphalt concrete around the rainwater grate is damaged, the rainwater collection well is directly accelerated to be damaged, the use function of a road is influenced, and great potential safety hazards exist.

SUMMERY OF THE UTILITY MODEL

In order to solve the technical problem, the utility model provides a convenient to use, reduction are measured repeatedly, are improved efficiency of construction's well grate erector has solved rainwater grate axis off normal big effectively, and the elevation is inaccurate, and the rainwater grate receives external force extrusion and destroys the deformation, quality problems such as the bituminous concrete is relatively poor with rainwater grate roughness on every side.

In order to achieve the above purpose, the utility model is realized by adopting the following technical scheme:

the utility model discloses a well grate erector, including square frame, install perpendicularly in two crossbeams of frame and the T type connecting rod that vertically runs through the crossbeam and be used for interim hoist and mount well grate, two of one side of stand and opposite side two of stand difference height-identical, two of one side stand and opposite side there is the difference in height in the stand.

Preferably, the lower end of the upright post is provided with a universal wheel.

Preferably, the position of the cross beam in the frame is adjustable.

Preferably, the transverse position and the longitudinal position of the T-shaped connecting rod mounted on the cross beam can be adjusted.

Compared with the prior art, the beneficial effects of the utility model are that: according to the size of the well grate, the positions of the cross beam and the T-shaped connecting rod are determined, the rainwater grate is temporarily hoisted by the T-shaped connecting rod, the position of the rainwater grate is fixed after the rainwater grate is checked to be accurate, the position and the gradient of the well grate are determined after the positions of the cross beam and the T-shaped bolt are adjusted, the well grate is directly used when being installed next well grate, repeated measurement is reduced, a wood plugging wedge is not needed at the bottom of the well grate, the construction efficiency can be improved, and the construction cost is reduced; the rainwater grate effectively solves the quality problems that the rainwater grate has large axis deviation and inaccurate elevation, the rainwater grate is extruded and damaged by external force and deformed, the flatness of the surrounding asphalt concrete and the rainwater grate is poor, and the like.
