Description

Technical Field

[0001] This invention relates to the field of high-speed railway track slab production technology, specifically to a device that automatically grabs the steel reinforcement skeleton of ballastless track slabs and automatically positions and installs it into a mold. Background Technology

[0002] In the pre-tensioning process of producing ballastless track slabs for high-speed railways, a steel reinforcement cage containing prestressed steel bars needs to be hoisted and installed inside the mold before concrete pouring. The prestressed steel bars are then tensioned, and the track slab is then formed and poured. Because the steel reinforcement cage is composed of several bent and tied individual steel bars, with prestressed steel bars inserted in between, the cage has a relatively large area and weight. During hoisting, if too few hoisting points are set, the steel reinforcement cage is prone to deformation. However, if too many hoisting points are set, although deformation is smaller, the tooling is cumbersome, requiring significant manpower and resources to ensure proper fit with the mold. Currently, in the pre-tensioning assembly line production of ballastless track slabs, several track slab specifications are produced, each requiring a different steel reinforcement cage. When multiple specifications of track slabs are produced on the same production line, there are also compatibility requirements for the equipment used to hoist different steel reinforcement cages. The equipment needs to be capable of rapid and automated adjustment between different specifications to ensure high efficiency in hoisting and installing the steel reinforcement cage and to prevent disruption to the assembly line process.

[0003] Due to the irregular shape of the steel reinforcement cage and the complex factors of the prestressed steel reinforcement installed within it, there is currently no equipment that can automatically adjust it to meet the needs of different specifications and applications.

[0015] This invention utilizes a densely arranged automated rebar hooking device to ensure uniform stress on the rebar cage during hoisting operations. Furthermore, the addition of a positioning device prevents deformation of the rebar cage during lifting. To accommodate the double-layer rebar structure of the cage, a double-layer frame is employed, and the rebar hooking device uses a double-hook mechanism for a wider hooking range. By installing a perforated sliding plate between the guide connectors of the rebar hooking device and the positioning device, the distance between them is adjustable, allowing the equipment to hoist rebar cages of different specifications.

The lower end of the guide plunger is an inner cone 403-3 that matches the outer shape of the jig cone 14 for guidance, so that the rebar cage positioning and hoisting device and the prestressed steel bars of the rebar cage 13 placed in the jig are accurately positioned.

[0073] Step 1.2: The ends of several long prestressed steel bars (two rows) of the steel cage 13 are inserted into the groove plate B1003 of the positioning plate C10. The double hook device 202 of the three-row long steel bar positioning hook mechanism 2 is ready for connection and hooking. The lifting cylinders 203-5 of the two lifting devices A203 press down the connecting slider 203-3 simultaneously, so that the long guide rod 201 connected to the U-shaped body 203-1 descends horizontally, so that several action rods 202-5 slide down along the fixed groove 202-7, so that the small rack 202-12 drives the two small gears 202-12 to rotate, so that the small hook 202-11 rotates 90 degrees around the small gear 202-12 (gear shaft 202-10) and hooks several (two rows) long prestressed steel bars.

[0074] Step 1.3 (operating simultaneously with Step 1.2) involves inserting the ends of several short prestressed steel bars of the steel cage 13 into the grooves A802 of the positioning plates A8 and B9. The single hook device 303 of the three-row short steel bar positioning hook mechanism 3 is ready to connect the hook. The lifting cylinder 203-5 of the three lifting devices B302 simultaneously presses down the connecting slider (with inner hole 302-1), causing the extended guide rod 301 connected through the inner hole 302-1 to descend horizontally. This causes several long moving rods 303-1 to slide downward along the long fixed groove 303-3, driving the small rack 202-12 to rotate. This causes the small hook 202-11 to rotate 90 degrees around the small gear 202-12 (gear shaft 202-10), hooking several short prestressed steel bars.

[0075] Step 1.4: A rebar cage positioning and hoisting device is lifted by a hoisting device, moving the rebar cage 13 (including prestressed steel bars) above the mold 11. The positioning adjustment cylinder 403 of the adjustable guide positioning device 4 is activated, extending the guide plunger 403-2 so that the lower end of the guide plunger is an inner cone 403-3 that matches the outer shape of the cone 12 of the mold 11. The rebar cage positioning and hoisting device descends, and the guide plunger 403-2 of the positioning adjustment cylinder 403 of the adjustable guide positioning device 4 is passively retracted, so that the balls 705 of the six sliding positioning hoisting seats 7 contact the upper plane of the side mold of the mold 11. The balls 705 slide and correct the positioning on the side mold, so that the prestressed steel bars of the rebar cage 13 grabbed by the rebar cage positioning and hoisting device are accurately located inside the mold 11.

[0076] Step 1.5: The lifting cylinders 203-5 of the two lifting devices A203 synchronously lift the connecting slider 203-3, causing the long guide rod 201 connected to the U-shaped body 203-1 to be horizontally lifted, causing several actuating rods 202-5 to slide upward along the fixed groove 202-7, causing the small rack 202-12 to drive the two meshing small gears 202-12 to rotate, causing the small hook 202-11 to rotate around the small gear 202-12 (gear shaft 202-10) by -90 degrees, disengaging from several (upper and lower rows) long prestressed steel bars.

[0077] Step 1.6 (operating simultaneously with Step 1.5): The lifting cylinder 203-5 of the three lifting devices B302 synchronously lifts the connecting slider (with inner hole 302-1), causing the extended guide rod 301 connected through the inner hole 302-1 to be horizontally lifted, causing several long moving rods 303-1 to slide upward along the long fixed groove 303-3, causing the small rack 202-12 to drive the meshing small gear 202-12 to rotate, causing the small hook 202-11 to rotate around the small gear 202-12 (gear shaft 202-10) by -90 degrees, disengaging from several short prestressed steel bars. A steel cage positioning and hoisting device is lifted away from the mold 11 by the hoisting equipment.

[0078] The completed specification 2 steel cage 13 (including prestressed steel bars) is placed in the jig;

[0079] When a rebar cage positioning and hoisting device is initially set to specification 1 and then changed to specification 2:

[0080] Step 2.1: Adjust the distance between the two adjustable guide positioning devices 4, extend / retract the displacement adjustment cylinder 406, push and pull the positioning adjustment cylinder 403 to slide forward / backward along the two large slide rails 402, the displacement adjustment cylinder 406 can stop at one of the three positions, the displacement adjustment cylinder 406 is locked, so that the distance between the two adjustable guide positioning devices 4 is the same as the distance between the two far-end cones 12 of the mold 11 of specification 2.

[0081] Step 2.2: Adjust the spacing of several single hook devices 303 of the two short steel bars positioning hook mechanism 3 on the outside of the rigid frame 1, and adjust the spacing between several positioning plates A8 and / or positioning plates B9 connected in pairs.

[0082] The spacing adjustment cylinder A501 extends / retracts, and the positioning plate B9 and the slider connecting plate B, connected by the piston rod end connecting shaft 503, move synchronously along the axial direction of the extended guide rod 301. The spacing between several positioning plates A8 and / or positioning plates B9 connected in pairs is adjusted by the combination and arrangement of the fixed plate 310 and / or sliding plate 311 and the hole spacing (sliding hole spacing). The spacing of several steel bar hook devices 303 fixed by the slider connecting plate B is also limited by the combination and arrangement of the fixed plate 310 and / or sliding plate 311 and the hole spacing (sliding hole spacing).

[0083] Step 2.3 (works simultaneously with step 2.2): The spacing of several single hook devices 303 of the short steel bar positioning hook mechanism 3 near the middle section of the rigid frame 1 is adjusted.

[0084] Adjust the extension / retraction of the hydraulic cylinder 603. The single trunnion 702 at the piston rod end is connected to the positioning plate B9 for synchronous displacement. The spacing between several positioning plates A8 and / or positioning plates B9 connected in pairs is adjusted by the combination and arrangement of the fixed plate 310 and / or sliding plate 311 and the hole spacing (sliding hole spacing).

[0085] Step 2.4, perform steps 1 (1.1~1.6) of specification 1.

[0086] The completed specification 3 steel cage 13 (including prestressed steel bars) is placed in the jig;

[0087] When a rebar cage positioning and hoisting device is initially set to specification 2 and then changed to specification 3:

[0088] Performing steps 2 (2.1.~2.3) differs in that the two sets of head-to-head spacing adjustment cylinders A501 extend / retract synchronously or asynchronously, enabling four position adjustments.

[0089] When a rebar cage positioning and hoisting device is initially set to specification 3 and then changed to specification 4:

[0090] The preset fixed position of the spacing adjustment cylinder A501 on the carbide profile 101 (along the inverted T-groove 102) is adjusted by loosening / tightening the T-screw 202-2. The preset fixed position of the adjustment cylinder 603 on the carbide profile 101 (along the inverted T-groove 102) is adjusted by loosening / tightening the T-screw 202-2. The spacing setting is adjusted by changing the fixing plate 310 and / or the sliding plate 311 (the width of the sliding hole).

[0091] Perform the steps of Specification 1 (1.1~1.6).

[0092] This invention features a compact structure and precise operation. By pre-identifying the specifications of the mold 11 (rebar cage 13), the spacing can be automatically adjusted in advance, allowing for the rapid transfer and positioning of rebar cages of different specifications when they enter the mold. This satisfies the production efficiency and quality control requirements of assembly line operations, effectively improving production progress.

[0093] The above describes the specific structural form of the present invention. The present invention is not limited to the above embodiments. For those skilled in the art, equivalent changes to the specific structure and component substitutions based on the present invention are all within the protection scope of the present invention.
