Operation mechanism of self-propelled multifunctional border stone slip form machine

Abstract

The invention discloses a forming die working mechanism of a self-propelled type multifunctional curb sliding mode machine in the technical field of concrete continuous paving device. When the working mechanism paves dry hard concrete, a construction has the advantages of stable shaping, high compactness and good planeness; the working mechanism includes a shaping die and a die hopper; the shaping die is arranged below the die hopper; the shaping die includes a front plate, a first side plate and a second side plate; the first side plate and the second side plate are respectively connected at the two sides of the front plate; a template is arranged between the first side plate and the second side plate; the shaping die is hinged with the die hopper through a pivot device; the pivot device is connected with the front plate of the shaping die and the front side surface of the die hopper; besides, the working mechanism also includes an externally arranged oscillator; the oscillator is connected with the template through a connecting frame.

Description

technical field [0001] The invention belongs to the technical field of continuous concrete paving equipment, and in particular relates to a forming mold working mechanism of a self-propelled multifunctional curb sliding form machine. Background technique [0002] The connection between the forming mold and the mold hopper of the existing self-propelled sliding form machine adopts a rigid method. In the case of hard concrete, steps and indentations often appear on the surface of the curb, and satisfactory flatness cannot be obtained; at the same time, because the dense dry hard concrete in the rigid mold is not easy to deform, the rigid mold must overcome when the traction main engine advances. The shear resistance of dense concrete, if the width of the paved curb is large, the shear resistance will be greater, and the slipform machine will slip when it advances on the roadbed, causing the slipform machine to break when it is running. Continuing, the direction cannot be cont...

[0002] The connection between the forming mold and the mold hopper of the existing self-propelled sliding form machine adopts a rigid method. In the case of hard concrete, steps and indentations often appear on the surface of the curb, and satisfactory flatness cannot be obtained; at the same time, because the dense dry hard concrete in the rigid mold is not easy to deform, the rigid mold must overcome when the traction main engine advances. The shear resistance of dense concrete, if the width of the paved curb is large, the shear resistance will be greater, and the slipform machine will slip when it advances on the roadbed, causing the slipform machine to break when it is running. Continued, unable to control the direction, the line of the curb is not beautiful, and it cannot be paved normally

Moreover, the existing slipform machine uses plug-in vibrating rods for dense molding, and the required concrete slump must be stable within a reasonable range; if the concrete slump is too high, the paved structure is prone to deformation ; If the concrete slump is too low, the workability of the concrete is poor, and it is difficult for the vibrating rod to compact it evenly, and the structure will have defects such as incompleteness and internal potholes.

This type of slipform machine has high requirements on the slump of concrete at the construction site. In order to meet this requirement, it is necessary to use a forced mixing station for mixing, and a concrete mixer truck for transportation, which increases the project cost.
