Automatic control reverse pushing-type multilayer color concrete slip-form paver

Abstract

The invention discloses an automatic control reverse pushing-type multilayer color concrete slip-form paver. One side of a frame (22) is installed with an eccentric feeding mechanism (15), a base material hopper (16) and a color material hopper (18); the lower parts of the base material hopper (16) and the color material hopper (18) are communicated with a base material molding mould (17) and a multilayer color material molding mould (19); the output shaft of the multiple output shaft gear box (3) on an engine (1) is connected with the eccentric shaft of the eccentric feeding mechanism (15) through a driving belt (14) and a driving chain (13); the front part of the frame (22) is installed with an elevation adjustment oil cylinder (8), a steering adjustment oil cylinder and a steering arm (7); the rear part of the frame (22) is installed with a back wheel (20) and a back wheel-supported adjustment oil cylinder (21). The invention has compact structure and simple and convenient operation, can realize multilayer color concrete continuous paving by operating once, and can improve the construction quality, construction efficiency and appreciation of curbs.

Description

technical field [0001] The invention relates to concrete continuous paving construction equipment, in particular to an automatic control reverse push type multi-layer colored concrete sliding form paving equipment. Background technique [0002] At present, in highway construction, the curb stones commonly used include concrete prefabricated curb stones, stone cut curb stones, artificial marble cut shaped curb stones, etc. These curb stones are transported to the construction site and manually installed and shaped; there are: 1. The working environment is poor, the construction intensity is high, the work efficiency is low, and the operation cost is high; 2. The whole construction process is greatly affected by environmental and human factors, and the installation line and elevation are not easy to control, and the operation quality is low; 3. On the same structure Only a single color can be formed, and multiple constructions are required to lay multi-layer colored concrete. ...

[0002] At present, in highway construction, the curb stones commonly used include concrete prefabricated curb stones, stone cut curb stones, artificial marble cut shaped curb stones, etc. These curb stones are transported to the construction site and manually installed and shaped; there are: 1. The working environment is poor, the construction intensity is high, the work efficiency is low, and the operation cost is high; 2. The whole construction process is greatly affected by environmental and human factors, and the installation line and elevation are not easy to control, and the operation quality is low; 3. On the same structure Can only form a single color, if laying multi-layer colored concrete requires multiple constructions

[0003] The existing concrete continuous paving equipment adopts self-vibration or vibration mode. In order to avoid leakage of material and slurry, the mold of this paving equipment is equipped with fixed side plates on both sides of the mold and a floating retaining plate. When paving, concrete is filled between the fixed side slab and the floating baffle. When the concrete reaches the initial setting time, the concrete between the side slab and the floating baffle will solidify, and the movement resistance of the floating baffle increases. When the elevation of the road surface changes, the floating baffle cannot produce relative movement, which will cause two situations, one is material leakage or slurry leakage, the other is the increase of driving resistance, and the paving equipment cannot move forward, no matter what happens , it is impossible to avoid the contradiction between walking speed, paving density and linearity, elevation and apparent quality; if concrete with large slump is paved, although the compactness is easy to guarantee, the linearity, elevation and apparent quality are relatively low. Poor; if paving concrete with a small slump (dry hard concrete), the line shape is easy to guarantee, but the elevation, compactness, and apparent quality cannot be guaranteed; moreover, the paving equipment uses a rigidly connected formwork. The relative position is used to adjust the flatness of the pavement. Its defect is: when the elevation needs to be lowered, the mold cannot be lowered due to too much mixture under the mold; when the elevation needs to be raised, due to insufficient mixture under the mold, Although the mold itself has been raised, the height of the structure itself has not been raised. At this time, the feed to the feed port has increased instead, causing the height to drop when it cannot be lowered, resulting in an uncontrollable height of the structure; In addition, the mold of the paving equipment also has a hinged connection, which makes the concrete dense through vibration. The weight and external force of the mold itself are not enough to make the concrete dense, and the line shape and elevation cannot be controlled; moreover, the existing concrete Paving equipment can only pave single-layer, single-color concrete structures, and continuous paving of multi-layer colored concrete cannot be achieved in one operation
