Line molding concrete sleepers

 

(57) Abstract:

The invention relates to the production of concrete sleepers and can be used in lines for the manufacture of concrete sleepers with the use of rotary seals the concrete mix. The purpose of the invention - improving line efficiency and quality sleepers. Line molding concrete sleepers comprises an area of 2 stacking in multi-form concrete mixture and simultaneous compaction by rotary paver 5. The line is equipped with a device for installation of anchors being formed in sleepers. made in the form of one mobile manipulator 10 and stationary manipulators 11 and 12. Multi-form 3 comes from the area of tension reinforcement on the conveyor 7, moved them to the limit stop 8 and stops. Further, the power cylinders of all stationary manipulators 11 and 12 at the same time lift up the head plate 15 and secured to them the holders and the diaphragm 17. The holders are holes in the bottom of the form 3. The movable arm 10 is moved to the extreme left position. By means of a power cylinder rod anchors pulled out of the stores and are pinned on the holders. The installation process dowels combined with the styling and Walter followed a movable arm 10. 2 C.p. f-crystals, 9 Il.

The invention relates to the production of concrete sleepers and can be used in lines for the manufacture of concrete sleepers using rotational laying and compaction of concrete.

Known production line for wooden sleepers, including a download site sleepers, the autoclave discharge Assembly, fixture drawing on the sides of the sleepers thermoplastic plates and the actuator [1].

The disadvantages of the known line are the low strength of the resulting sleepers and the impossibility of making it durable sleepers of concrete.

Famous line for molding concrete sleepers, containing the site of placement of concrete mixture in multiple forms and simultaneously sealing the mixture in the form [2] is a prototype.

A disadvantage of the known line is low productivity due to the lack of mechanization of works on installation in form and subsequent extraction of the hole-forming cores and diaphragms, as well as the installation in the form of embedded fasteners (e.g., cage washers, dowels, etc.,).

In addition, the use during manual work when removing a removable snap-in tools such as "derisively line and quality sleepers.

This objective is achieved in that the line forming concrete sleepers, containing of land laying in multi-form concrete mixture and simultaneous compaction, provided with a device for installation of anchors being formed in sleepers, made in the form of one of the rolling and stationary manipulators, and average stationary manipulators made in the form of mounted from the bottom of the form vertically movable traverse: on the upper surfaces of traverse medium manipulators of a number of fixed holders, and on the upper surfaces of the traverse at the stationary manipulators installed aperture; moving the pointing device in the form of portal equipped with shops anchors and vertical power cylinders to move the anchors of shopping and the nozzle plugs on the holders.

The invention has the following differences from the prototype:

line molding concrete sleepers, containing of land laying in multi-form concrete mixture and simultaneous compaction, provided with a device for installation of anchors in the form of the sleepers, made in the form of one of the rolling and stationary manipulators;

average stationary manipulators done the traverse medium manipulators of a number of fixed holders, and on the upper surfaces of the traverse at the stationary manipulators installed aperture;

the mobile manipulator is designed as a portal with shops anchors and vertical power cylinders to move the anchors of shopping and the nozzle plugs on the holders.

This will increase the line capacity and quality sleepers.

Viewed in us patent information the Fund has not found similar technical solutions, and solutions with these distinctive features.

The invention is applicable and will be used at the enterprises of the industry in 1996-1997

In Fig.1 shows a diagram of lines forming concrete sleepers, front view; Fig.2 - the same, lateral view; Fig.3 - the same, top view; Fig.4 - scheme of rolling and medium stationary manipulators in the working position, the front view of Fig.5 - the same, lateral view; Fig.6 - slice multi-form entered into the holders, and Fig.7 is the same, the moment of introduction in the form of the dowel of Fig.8 is the same, the time of removal of the holder from the formed billet of Fig. 9 is a fragment formed ties with established therein plugs.

Line molding VC is drop-through rotary paver 5, which moves along rails 6. To move multiple forms 3 has a roller 7, and at the end of section 2 has a restrictive emphasis 8 with a limit switch (not shown) of the drive roller 7.

The line is equipped with a device for installation of anchors 9 in the form of the sleeper 1, made in the form of one mobile manipulator 10 and stationary manipulators 11 and 12. Stationary arms 11 and 12 made in the form mounted on the base 13 from the bottom 14 multiple forms 3 vertically movable traverse 15, and the upper surfaces of the traverse 15 secondary stationary manipulators 12 fixed holders 16 and on the upper surfaces of the traverse 15 at stationary manipulators 11 set the aperture 17. Movable head plate 15 is moved by the rack 18 by means of a power cylinder 19. The holders 16 by hinges 20 are attached to the cross beam 15 and have a variable cylindrical cross-section. The lower thickened portion of the holder 16 with a conical transition is used to fasten the anchors 9, and the upper for the formation of through holes 21 in the sleeper 1 (Fig.6 and 9).

The movable arm 10 is made in the form of portal 22 based on the drive rollers 23, which moves the elegance of the power cylinders 25 and 26, respectively, to move the anchors 9 from the store 24 and nozzle plugs 9 to the holders 16, protruding from the holes 27 of the bottom 14 multiple forms 3. In the bottom 14 multiple forms there are 3 slots for placement of the apertures 17. The power cylinder 25 has a piston rod 29, and the power cylinder 26 is a piston rod 30.

The line works as follows. Multi-form 3 comes from the previous processing area, namely the area of tension reinforcement (not shown) on the conveyor 7 and moves them to the limit stop 8, at the moment of contact which actuates limit switch and switches off the drive of the conveyor 7. This multi-form 3 is stopped at the position at which the holders 16 medium stationary manipulators 12 and the aperture 17 at the stationary manipulators 11 are located opposite the respective openings 27 and grooves 28 of the bottom 14 of form 3. The power cylinders 19 all stationary manipulators 11 and 12 at the same time lift up the head plate 15 and secured to them the holders 16 and diaphragm 17. The holders 16 are holes 27 of the bottom 14 of the form 3, i.e., occupy a working position (Fig.6). At this time, the rotary paver 5 is under load in the zone betononasos rack (not shown) and the movable arm 10 is in the leftmost position, i.e., opposite lovage cylinder 26 by the rod 30 dowel 9 out of the store 24 and is placed on the holder 16. And placed 4 dowels 9. Then the power cylinder 26 returns the rod 30 to its original position, and released from the anchor 9 in the store 24 is engaged by the other, which is pushed by store 24 by means of the rod 29 of the power cylinder 25. Next, the movable arm 10 is moved to the right to the next medium stationary arm 12, and repeats the whole process described.

After installing the plugs 9 in the rightmost position of a form 3 mobile manipulator 10 is displayed outside of site 2. The installation process dowels 9 is combined with the laying and compacting of concrete mixture 4 in the form of 3 carried out by rotary paver 5, moving from left to right behind a movable arm 10.

After forming the paver 5 moves for loading in the area betononasos trestle. Form 3 with molded sleepers moved by crane to the next technological area - in the steam chamber (not shown), and on the vacant plot 2 plot tension valve is moved to another bench form 3, after a stop which is movable arm 10 is moved to the initial leftmost position. The cycle is repeated.
