Fully automatic intermediate tie rod inserter for slipform paver

Abstract

The invention discloses a full-automatic middle pull rod inserter of a sliding die paver. The full-automatic middle pull rod inserter comprises a guide chute, wherein a steel bar pull rod is placed in the guide chute; a push rod is arranged at one side of the guide chute; the lower end of the push rod is connected with a feeding shaft; a feeding roller is mounted on the feeding shaft; the lower end of the guide chute is sealed by the circumferential surface of the feeding roller; an inserting rod is arranged on the other side of the guide chute; the side edge of the inserting rod is close to the circumferential surface of the feeding roller; a receiving opening is formed in one side of the inserting rod; a fixing base is arranged at the top end of the push rod; a mounting base is arranged at the upper middle part of the push rod; a compression spring is arranged between the fixing base and the mounting base; a pressing rod is arranged at the top end of a power device; the pressing rod is located right above the push rod and is capable of pushing the push rod to move up and down. Due to the adoption of the structure, the full-automatic middle pull rod inserter of the sliding die paver is simple in structure and convenient to operate, so that functions of automatically feeding the pull rod and automatically inserting the pull rod at an equal interval can be realized.

Description

technical field [0001] The invention relates to an accessory of a slip-form paver, in particular to a fully automatic middle tie rod inserter for a slip-form paver, which belongs to the technical field of road construction machinery. Background technique [0002] According to the highway cement concrete pavement design specification, when paving a cement concrete pavement with a width greater than 4.5m at one time, longitudinal shrinkage joints should be set; the longitudinal shrinkage joints should be in the form of false joints with tie rods, and the tie rods are threaded steel bars, which are located in the center of the slab thickness; traditional On the one hand, the intermediate tie rod inserter has no automatic feeding function. After each threaded steel bar is driven in, another threaded steel bar needs to be manually inserted again. The operation is complicated and labor-intensive; on the other hand, the insertion distance is controlled by a sensor distance measureme...

[0002] According to the highway cement concrete pavement design specification, when paving a cement concrete pavement with a width greater than 4.5m at one time, longitudinal shrinkage joints should be set; the longitudinal shrinkage joints should be in the form of false joints with tie rods, and the tie rods are threaded steel bars, which are located in the center of the slab thickness; traditional On the one hand, the intermediate tie rod inserter has no automatic feeding function. After each threaded steel bar is driven in, another threaded steel bar needs to be manually inserted again. The operation is complicated and labor-intensive; on the other hand, the insertion distance is controlled by a sensor distance measurement feedback Manually control the switch of the intermediate tie rod inserter after the indicator light or alarm is detected. Due to manual operation, it will inevitably affect the distance between the driving rods, thus affecting the quality of the cement pavement
