Abstract

FIELD: mechanical engineering; materials handling transportation of loads on platforms along closed route. SUBSTANCE: conveyor has load carrying platforms which rest on rails through running wheels. Rails form closed rectilinear route. Platforms have additional running wheels whose axles are perpendicular to axles of other wheels. Rails in corner sections are provided with intake rollers whose axes coincide with longitudinal axes of rails. EFFECT: enlarged operating capabilities. 5 dwg

Description

 The invention relates to the field of conveyor engineering, in particular to freight truck conveyors designed to transport trolleys with goods using an autonomous drive.

 Known freight truck conveyor, including a support trolley with wheels, a channel in which is located a traction chain with pushers (ed. St. USSR 929511, class B 65 17/38, 1980).

 The disadvantage of this conveyor is that it moves by means of a traction chain, and the support of the wheels directly on the floor increases the height of the support trolley, which causes inconvenience during assembly work. Also, this conveyor does not move the support trolley along a closed rectangular path.

 A well-known horizontal horizontally closed truck conveyor, consisting of a supporting platform, axles with track rollers moving along the track in the form of rails, guiding elements preventing the lateral displacement of the platform, and platform moving wires (RL Zenkov and other conveyors, reference book, L. Engineering, 1984, p. 270 274).

 This conveyor, selected as a prototype, at a low height, which is convenient for assembly operations, also has disadvantages. And the main drawback is the inability to move the platform from one running track to another, located perpendicular to the first.

 The basis of the invention is the creation of a horizontally closed bogie conveyor, which allows supporting platforms along mutually perpendicular running tracks.

 The specified technical result is achieved by the fact that the supporting platform is equipped with additional rollers mounted on the axes perpendicular to the axles of the main rollers.

 In FIG. 1 shows a truckload horizontally closed conveyor; in FIG. 2 the same, partial cut-out; in FIG. 3, section AA in FIG. one; in FIG. 4 node of mutual fastening of the main and additional rollers; in FIG. 5 is a section BB in FIG. 4.

 A freight-carrying horizontally-closed truck conveyor includes carrier platforms 1, four drives 2 for moving platforms 1. Platforms 1 are supported on rails 4 through main rollers 4 mounted on axles 5. On platforms 1 there are additional rollers 6 that are mounted on axles 7 perpendicular to axles 5 The rails 3 are laid in two rows in the channel 8 below the floor and form a closed rectangular path. To facilitate the transition of track rollers 4 or 6 to your rail, in angular mutually perpendicular sections, the rails are made with receiving rollers 9 and 10, which are installed in rails 3 on axes 11 and 12, coinciding with the longitudinal axes of the rail in which they are installed. From the lateral displacement of the platforms 1 protect the guide rollers 13, mounted along the entire track on the brackets 14.

 Cargo horizontally closed truck conveyor operates as follows. Bearing platforms (trolleys) 1 are positioned along the track in such an amount that there is room for another platform (trolley) 1. In this design of the conveyor, four drives 2 are used, which are located one on each of the branches of a rectangular track. If we take the layout of the platforms in FIG. 1, the drive located in the left corner of the upper long section of the track will be the first to turn on. He will move the platform to the upper right free corner, and then the drive located from the first counterclockwise, etc. will turn on. That is, each subsequent drive, moving platforms 1, will leave in its corner free space for platforms from another branch of the route. When the platform 1 approaches the free angle, the rollers, for example 4, rolled along the rails 3 will roll onto the receiving roller 9, and the rollers 6, which, when the platform 1 was moved due to its displacement relative to the rollers 4, did not interact on this section of the track with the rails 3, will be installed on the receiving roller 10, which, taking the roller 6, will turn on its axis 12. Now that the turn of this platform is suitable to change its movement perpendicular to the one along which it moved, the roller 4 will easily come off the roller 9, since the latter is attached ii thrust to the platform just turn on its axis 11 and the roller 6 will roll with the receiving roller 10 on a rail 3.

 The proposed conveyor design allows you to move the platform (trolley) on a rectangular closed path without the application of large traction forces.
