Sand screening device for simple bridge construction

Abstract

The invention discloses a sand screening device for a simple bridge construction. The sand screening device comprises a box body, guide rails, sliding blocks, a screening frame, a cam, a discharging inclined plate and a moving wheel, wherein guide rails are obliquely arranged on the front side and the rear side of the inner wall of the box body, the sliding blocks are movably arranged on the guiderails, the sliding blocks are fixedly connected with the top of the screening frame, the screening frame and the guide rails are perpendicular to each other, the side, close to the screening frame, of a mounting plate is provided with a motor through bolts, an output end of the motor is connected with a cam through a coupling, the side, far away from the cam, of the screening frame is connected to the inner wall of the box body through springs, the discharging inclined plate is arranged at the bottom in the box body, the side, far away from the cam, of the discharging inclined plate penetrates to the outer side of the box body, and a discharging port is formed in the position, on the discharging inclined plate, of the outer side of the box body. According to the sand screening device forthe simple bridge construction, the guide rails are obliquely arranged, so that the screening frame continuously gets close to the cam due to the gravity action, the cam rotates to continuously beat the screening frame, so that the screening frame can continuously move left and right along the guide rails, and sand can be quickly screened.

Description

technical field [0001] The invention relates to a sand screening device, in particular to a simple sand screening device for bridge construction, and relates to the field of bridge construction. Background technique [0002] Bridges generally refer to structures erected on rivers, lakes and seas to allow vehicles and pedestrians to pass smoothly. In order to adapt to the modern high-speed development of the transportation industry, bridges are also extended to buildings that cross mountain streams, poor geology or meet other transportation needs to make traffic more convenient. A bridge is generally composed of a superstructure, a substructure, a support and ancillary structures. The superstructure is also called a bridge span structure, which is the main structure for crossing obstacles; the substructure includes abutments, piers and foundations; Or the force transmission device installed at the supporting place of the bridge abutment; the auxiliary structures refer to the...
