Description

Technical Field

[0001] The utility model relates to the technical field of circular pipe culvert manufacturing, in particular to a prefabricated unloading platform cap for a circular pipe culvert. Background Art

[0002] In the construction of reinforced concrete circular culverts, circular culverts are usually prefabricated in factories. The traditional prefabrication process uses direct unloading operations with chutes, by pouring cement into the circular culvert mold. However, the cement unloading process is often that the cement mixer truck unloads cement from one end of the circular culvert mold, which makes it difficult to evenly unload cement into the circular mold. Uneven unloading is prone to uncontrollable factors such as aggregate segregation and steel cage displacement, which is not conducive to ensuring the quality of circular culvert prefabrication and improving construction speed, and cannot meet modern production needs. Utility Model Content

[0003] In view of the shortcomings of the prior art, the utility model proposes a prefabricated unloading platform cap for a circular culvert to solve the technical problem mentioned in the above background technology that cement is often unloaded at a single point and is difficult to be evenly unloaded into the circular culvert mold around the periphery.

[0004] In order to solve this technical problem, the technical solution adopted by the utility model is:

[0005] A prefabricated unloading platform cap for a circular culvert is used to pour cement into a circular culvert mold, comprising an inner ring plate, a conical material guide platform, a connecting plate and a positioning plate;

[0006] The inner ring plate is placed on the inner ring top of the circular culvert mold, the conical material guide platform is arranged on the inner ring top, one end of the connecting rod is connected to the inner ring plate, and the other end is connected to the positioning plate, the positioning plate is provided with a positioning groove, and the positioning groove can be inserted into the outer ring of the circular culvert mold.

[0007] Furthermore, the conical material guiding platform comprises a conical plate, reinforcing ribs and a connecting plate; a plurality of circles of reinforcing ribs are arranged inside the conical plate, and the bottom of the conical plate is connected to the connecting plate.

[0008] Furthermore, an annular sliding groove is provided on the top of the inner ring plate, and a sliding plate is provided on the bottom of the connecting plate, and the sliding plate can be slidably arranged in the sliding groove; a driven block is coaxially fixed in the conical plate, and a driven groove is provided in the driven block, and a driving component is also provided in the inner ring plate, and the driving component can be inserted into the driven groove and can drive the driven block to rotate.

[0009] Furthermore, the driving assembly includes a fixed plate, a motor and a driving block; the fixed plate is fixed in the inner ring plate, the motor is fixed on the fixed plate, the driving block is coaxially fixed on the output shaft of the motor, and the driving block and the driven groove are connected by a spline.

[0010] Furthermore, a hook is provided on the conical plate.

[0011] Compared with the prior art, the advancement of this application is:

[0012] Cement is poured into the top of the conical material guide table through a cement mixer. The cement flows into the circular culvert mold along the four sides of the conical material guide table, so that the cement is discharged into the mold more evenly, avoiding problems such as deformation and displacement of the steel cage during unloading.
