Abstract

FIELD: reinforced tie production; stacking of ties for storage. SUBSTANCE: ties made with under-rail pads are delivered to stacker with pads pointed upwards. Ties in tiers are arranged so that pads form two rows of cavities in each tier. Inter-tier spacer is placed in left-hand or right-hand row of cavities with tier-by-tier alternation of rows with displacement to left-hand or right-hand side walls of cavities in left-hand or right-hand row, respectively. EFFECT: enhanced quality of stacking and convenience of storage. 3 dwg

Description

 The invention relates to the production of reinforced concrete sleepers, in particular to the final phase of the manufacturing process, the formation of a package of finished products for subsequent transportation.

 A known method of forming packages of reinforced concrete sleepers having recesses under the rails. On each rail track of the sleepers, the details of the rail fastenings are installed, next to which wooden gaskets are laid, the height overlapping the height of the protruding part of the fasteners. In all cases, the subsequent sleepers of each tier with their sole rests on two wooden gaskets laid on previous sleepers.

 A known method of forming a package of reinforced concrete sleepers manufactured without rails, allowing the formation of a package without wooden spacers.

 There is a method of forming a package of reinforced concrete sleepers, adopted as a prototype, which is carried out by a series of sequential operations on the stacker and includes a set of sleepers in horizontal tiers, placing the latter under each other and resting the upper tiers on the lower tiers through wooden gaskets successively placed in all horizontal tiers of the sleepers.

 The disadvantages of this method are the large consumption of timber, a different amount of manual labor when laying inter-level gaskets, insufficient compactness of the formed package of sleepers.

 The purpose of the invention is the reduction of labor and material consumption in the formation of a package of having rail track platforms sleepers.

 This goal is achieved by the fact that sleepers made with rails are fed with rails facing upwards, which are coaxial with the set of tiers, forming two rows of recesses in each tier. The interlayer gasket is placed only in the left or right row of recesses with a tiered alternation of rows and with offset to the left or right side walls of the recesses, respectively, in the left or right row.

 These properties are not possessed by any of the known methods for forming packages of finished sleepers, which allows us to consider this method to meet the criterion of "significant differences".

 In Fig.1 shows a separate sleepers with rail recesses; figure 2 formed a stack; figure 3 view a in figure 2.

 The method of forming a package of reinforced concrete sleepers includes a certain sequence of operations. Finished products (sleepers) with upward-facing rail platforms 1, which move with the transverse pusher in the transverse direction, make up the horizontal tier, where the rail platforms are aligned and form two rows of recesses in each tier. After that, the tier is moved in a vertical plane by a hydraulic elevator and is fixed at a predetermined height by the stacker. From the finished sleepers, the next tier of sleepers is recruited, and the gasket 2 is placed only in the left or right row of recesses of the horizontal tier. Next, the second tier is lifted by a hydraulic elevator until it contacts a previously formed tier. On the one hand, each sleeper of the previous tier rests with its sole on the gasket, on the other hand, on the concrete elevation of the sleepers. The set box of the subsequent tier of the sleepers, the gasket is laid in adjacent under-rail recesses of the sleepers opposite to the previously laid gasket. After that, with a load-lifting traverse, the typed package of sleepers moves to the storage location. A package of reinforced concrete sleepers can be selected from a different number of sleepers, determined by the carrying capacity of the means used to deliver the sleepers to the consumer.

The test results of the above method of forming a packet of sleepers having an angle of 60 ^about positive. Numerous tests were carried out of the described method of forming packets, in particular for the formation of about 10 thousand packets with a total number of packed sleepers of 240 thousand pcs.

Claims (1)

 METHOD FOR FORMING A BEDSAW PACKAGE, including their longitudinal feed, set of tiers by shifting the sleepers in the transverse direction, laying at least one inter-level laying perpendicular to the sleepers with offset to one of the ends of the latter and subsequent placement of tiers one under the other, characterized in that, for the purpose reduce labor and material consumption when forming a package of sleepers having rail tracks, the latter are fed upwards with the formation in each tier of these platforms two rows of recesses and adka in one of them mentioned strip with tiered alternation and offset to the left or right side wall of the recess in the left or right row of the tier, respectively.
