Pavement cement paving device for road and bridge construction

Abstract

The pavement cement paving device for road and bridge construction comprises a material storage box body, and a rolling assembly, a flattening assembly and a smearing assembly are arranged at the bottom end of the material storage box body; walking assemblies are arranged on the two sides of the bottom end of the storage box body. A discharging opening is formed in the front end of the storage box body, and a blocking assembly is arranged above the outer side of the discharging opening; the material blocking assembly comprises a rotating motor, a bearing seat and a sliding block. A rectangular groove is formed in the front end of the storage box body, the rotating motor and the bearing pedestal are both fixed in the rectangular groove, the rotating motor is connected with one end of the lead screw through a coupler, and the other end of the lead screw is rotatably connected with the bearing pedestal; a penetrating through hole is arranged on the sliding block; the sliding block is connected to the outer side of the lead screw in a sleeving mode through the penetrating through hole, penetrates through the inner side wall of the through hole and is in threaded connection with the outer side wall of the lead screw. The front end of the sliding block is fixedly connected with a fixed plate, a first screw hole is formed in the fixed plate, a second screw hole and a third screw hole are formed in the movable plate, and the third screw hole is located above the second screw hole.

Description

technical field [0001] The invention relates to the field of road and bridge construction, in particular to a pavement cement paving device for road and bridge construction. Background technique [0002] Existing highway pavement is generally cement pavement or asphalt pavement, and cement pavement refers to the pavement that uses cement as the main material to make the surface layer, also known as rigid pavement, commonly known as white pavement, and it is a kind of high-grade pavement. It requires a cement paving device to smooth the cement surface to be laid, so as to achieve the flatness required by people. [0003] The cement pavement paving device in the prior art needs to suspend construction in order to avoid cement and other materials falling on the manhole cover when it encounters the manhole cover and sewer mouth on the road, and then manually repair the road section containing the manhole cover and sewer mouth. The tiling operation is time-consuming and laboriou...

Problems solved by technology

[0003] The cement pavement paving device in the prior art needs to suspend construction in order to avoid cement and other materials falling on the manhole cover when it encounters the manhole cover and sewer mouth on the road, and then manually repair the road section containing the manhole cover and sewer mouth. The tiling operation is time-consuming and labor-intensive, which seriously reduces the tiling efficiency of the cement pavement and brings certain troubles to the pavement paving work.
