Abstract

The invention relates to the technical field of sleeper production, and provides a screwing mechanism of a sleeper sleeve spiral rib. The screwing mechanism comprises a conveying line, fixing devices,a lifting electric cylinder, a screwing motor and a screwing sleeve. The fixing devices are arranged on the two sides of the conveying line. The lifting electric cylinder is arranged above the fixingdevices. The moving end of the lifting electric cylinder is connected with the screwing motor. An output shaft of the screwing motor is connected with the screwing sleeve. When a spiral rib sleeve iscarried to the positions of the fixing devices by the conveying line, the conveying line stops moving, the spiral rib sleeve is clamped by the fixing device, and the lifting electric cylinder arranged above the fixing devices is started to drive the screwing motor and the screwing sleeve to descend, so that the screwing sleeve is clamped with the spiral rib sleeve, and finally the screwing motoris started to drive the screwing sleeve to rotate, so that the spiral rib is screwed onto the sleeve. The screwing efficiency is high due to the adoption of mechanical screwing equipment; and moreover, the screwing force can be set according to the actual situations, the consistency of strength of screwing the spiral rib is ensured, a large amount of rework is avoided, and the production efficiency of the spiral rib sleeve is improved.

Description

technical field [0001] The present application relates to the technical field of sleeper production, in particular to a screwing device for the helical rib of a sleeper casing. Background technique [0002] Sleepers are generally made by pouring concrete materials into molds, waiting for them to solidify to form concrete blocks, and then demoulding. By prefabricating the sleeper in advance, transporting the prefabricated sleeper to the railway construction site, fixing and constructing the sleeper, in order to install and position other components on the sleeper in the future, it is necessary to set the casing at the preset position of the sleeper during the pouring and setting process of the sleeper. [0003] In order to screw other parts installed and positioned into or out of the sleeve, generally a spiral rib sleeve is preset on the sleeper. The spiral rib sleeve is a sleeve provided with a spiral rib outside the shell of the round table. The shape of the spiral rib corr...
