Description

Technical Field

[0001] The invention belongs to the technical field of T-beam production and processing, and specifically relates to a highway T-beam steel cage processing production line and a production method. Background Art

[0002] T-beam, also known as T-shaped beam, is a beam with a T-shaped cross-section. The protruding parts on both sides are called flanges (i.e., top plates), and the middle part is called beam ribs (i.e., bottom webs). The design concept of T-beam is to remove the concrete in the tensile zone of the rectangular beam that does not contribute to the bending strength, thereby saving concrete and reducing the deadweight of the component while maintaining the original rectangular bending strength, thereby improving the spanning capacity. T-beams are widely used in various building structures, especially in bridge engineering, where they are often used as the main load-bearing structure to form T-beam bridges.

[0003] The T-beam steel skeleton includes a top plate steel mesh and a bottom web steel mesh; in the prior art, the top plate steel mesh has a relatively standard rectangular mesh structure, which is more regular in shape, more convenient to manufacture, and has a more mature processing and production process; and the bottom web steel mesh is divided into a standard section and a thickened section in its extension direction, wherein the thickness of the standard section is smaller, while the thickness of the thickened section is larger, which makes the steel bar size of the standard section slightly different from that of the thickened section.

[0041] The invention also provides a highway T-beam steel cage processing and production method, the production method uses the above-mentioned highway T-beam steel cage processing production line, and the production method comprises the following steps:

[0042] Step 1, producing a roof steel mesh by a roof steel mesh production line; and at the same time, bending and welding the steel bars into stirrups by a stirrup bending and forming machine;

[0043] Step 2: After the bending and welding of the stirrups are completed, the stirrups are placed on the stirrup transfer rack in a set order;

[0044] Step 3, the stirrup transfer frame is driven by the AGV trolley to move inside the stirrup placement equipment, so that the stirrup transfer frame and a part of the stirrup tire frame are both located side by side inside the walking frame;

[0045] Step 4, the Z-axis walking mechanism moves downward from directly above the stirrup transfer frame, and then the correction unit straightens the stirrup, and the clamping unit clamps the stirrup; then the Z-axis walking mechanism drives the stirrup to move upward, so that the stirrup is separated from the stirrup transfer frame; then the Y-axis walking mechanism drives the Z-axis walking mechanism to move directly above the stirrup tire frame, the Z-axis walking mechanism falls, and the clamping unit releases the stirrup to the stirrup tire frame, thereby placing a group of stirrups on the stirrup tire frame;

[0046] Step 5, the AGV trolley drives the stirrup transfer frame back and continues to place stirrups on the stirrup transfer frame; then the stirrup placing equipment moves along the stirrup frame to the next station, and repeats steps 3-4 until all stirrups are placed on the card slots of the stirrup frame;

[0047] Step 6, two straightening and cutting machines at one end of the stirrup cradle straighten and cut the longitudinal bars and feed them to the conveying wheels on both sides of the stirrup cradle. When the longitudinal bars pass through the length reader, the length reader records the conveying length of the longitudinal bars; the transmission shaft drives the conveying wheel to rotate forward to convey the longitudinal bars to the downstream. When the conveying length of the longitudinal bars reaches the set value, the conveying wheel stops rotating and the longitudinal bars are cut by the straightening and cutting machine; the first-level jacking device drives the jacking plate to jack up, so that the longitudinal bars on the conveying wheel are cached in the first-level cache slot; repeat the above process until the set number of longitudinal bars are stored in the first-level cache slot; the second-level jacking device drives the jacking plate to jack up, so that multiple longitudinal bars in the first-level cache slot are cached in the second-level cache slot;

[0048] Step 7, the bottom longitudinal reinforcement threading frame at the other end of the stirrup tire frame transmits the bottom longitudinal reinforcement to the roller. When the conveying wheel completes the longitudinal reinforcement conveying on the side of the stirrup, the transmission shaft drives the roller to reverse, so as to thread multiple first-section longitudinal reinforcements to the bottom of the stirrup. After the first-section longitudinal reinforcement stops conveying, the first-section longitudinal reinforcement is manually connected with the second-section longitudinal reinforcement; when the first-section longitudinal reinforcement is connected with the second-section longitudinal reinforcement, the cutting, conveying and caching of the longitudinal reinforcement in the side material laying method are carried out synchronously; after the first-section longitudinal reinforcement is connected with the second-section longitudinal reinforcement, the transmission shaft drives the roller to reverse, and continues to thread the second-section longitudinal reinforcement to the bottom of the stirrup until the second-section longitudinal reinforcement is delivered in place; repeat the above process until all the bottom longitudinal reinforcements are threaded, and then the bottom longitudinal reinforcement and the stirrup are welded and fixed;

[0049] Step 8, after the longitudinal reinforcement on the side of the stirrup frame is cut, the stirrup combing mechanism extends out of the lifting platform to clamp and position the stirrup, and the longitudinal reinforcement on the side of the stirrup frame is placed into the guide groove of the longitudinal reinforcement combing mechanism by manual or mechanical hands, and the lifting platform is lifted relative to the main frame to adjust the vertical position of the longitudinal reinforcement relative to the stirrup, so that the longitudinal reinforcement is fixed at different positions of the stirrup; finally, the welding device extends out of the lifting platform, and welds at the intersection of the longitudinal reinforcement and the stirrup, so that the longitudinal reinforcement and the stirrup are accurately positioned and fixed; after the welding at the current position is completed, the welding equipment moves to the next station along the stirrup frame, and the above process is repeated until the stirrup and the longitudinal reinforcement on its side are completely welded and fixed;

[0050] Step 9: After all the stirrups and longitudinal bars are welded, the bottom web steel mesh is formed, and the bottom web steel mesh is hoisted to the corrugated pipe and auxiliary steel bar manual installation area using a gantry crane and a hoisting device to install the corrugated pipe and auxiliary steel bars;

[0051] Step 10. After the processing of the top plate steel mesh and the bottom web steel mesh is completed, first use the gantry crane with the lifting equipment to lift the bottom web steel mesh into the T-beam assembly and casting position, then lift the top plate steel mesh above the bottom web steel mesh, insert the longitudinal reinforcement into the overlapping area of ​​the top plate steel mesh and the bottom web steel mesh, and tie them up. At this point, the processing of the T-beam steel skeleton is completed, waiting for concrete pouring.

[0052] Beneficial effects:

[0053] The structural layout of the entire production line is more compact and reasonable, and the connection between each process is smoother, which facilitates improving production efficiency.

[0054] In the bottom slab steel mesh production line, two stirrup bending and forming machines are set up. The two stirrup bending and forming machines work simultaneously to produce stirrups of different widths and specifications, and place them on the stirrup transfer rack in a set order; when the stirrups on the stirrup transfer rack are full; the AGV trolley carries the stirrup transfer rack to the bottom of the stirrup placing equipment, and the Z-axis walking mechanism in the stirrup placing equipment moves downward from just above the stirrup transfer rack, and then the correction unit straightens the stirrups, and the clamping unit clamps the stirrups; then the Z-axis walking mechanism drives the stirrups to move upward, so that the stirrups are separated from the stirrup transfer rack; then the Y-axis walking mechanism drives the Z-axis walking mechanism to move just above the stirrup rack, the Z-axis walking mechanism falls, and the clamping unit releases the stirrups to the stirrup rack, thereby placing a group of stirrups on the stirrup rack; then the stirrup placing equipment moves along the stirrup rack to the next station, and the above steps are repeated until all stirrups are placed on the stirrup rack. Compared with manual placement of stirrups, the placement efficiency is effectively improved, and multiple stirrups can be corrected and placed at one time, ensuring the positioning accuracy of the clamped stirrups and improving work efficiency.

[0055] The bottom longitudinal reinforcement threading process and the side longitudinal reinforcement laying process can be staggered during the interval between the transmissions of the two, so that the same transmission shaft can control the rotation of the conveying wheel and the roller at the same time. The forward and reverse rotation of the transmission shaft can make the conveying wheel and the roller run in staggered order, thereby optimizing the construction process of the side longitudinal reinforcement laying and the bottom longitudinal reinforcement threading, thereby greatly improving the construction efficiency and reducing the construction cost.

When the stirrups 20 on the stirrup transfer rack are full, the stirrup transfer rack is carried by the AGV trolley to the bottom of the stirrup placing device 3, and the Z-axis walking mechanism 35 of the stirrup placing device 3 moves downward from just above the stirrup transfer rack, and then the correction unit 32 straightens the stirrup 20, and the clamping unit 31 clamps Take the stirrups 20; then the Z-axis walking mechanism 35 drives the stirrups to move upward, so that the stirrups 20 are separated from the stirrup transfer frame; then the Y-axis walking mechanism 34 drives the Z-axis walking mechanism 35 to move to just above the stirrup frame 10, the Z-axis walking mechanism 35 falls, and the clamping unit 31 releases the stirrups to the stirrup frame 10, thereby placing a group of stirrups on the stirrup frame 10; then the stirrup placing device 3 moves along the stirrup frame 10 to the next workstation, and repeats the above steps until all stirrups are placed on the stirrup frame 10.

[0096] In the reinforcement threading and laying unit 4, the transmission shaft 47 is controlled to rotate forward to transmit the longitudinal reinforcement 30 to both sides of the stirrup frame 10 through the conveying wheels 41 on both sides of the stirrup frame 10, and the multi-level cache component caches multiple longitudinal reinforcements 30 in sequence, so that the longitudinal reinforcements 30 cached in the multi-level cache component are subsequently welded to the side of the stirrup; the transmission shaft 47 is controlled to rotate reversely to drive the roller 48 to rotate, and the multiple longitudinal reinforcements 30 are transmitted to the bottom of the stirrup through the roller 48, so that the longitudinal reinforcements 30 are subsequently welded to the bottom of the stirrup.

[0097] Conveying wheels 41 are arranged on both sides of the stirrup frame 10 to facilitate the conveying and laying of the longitudinal reinforcement 30 on the side of the stirrup, and rollers 48 are arranged coaxially with the conveying wheels 41 to facilitate the insertion of the longitudinal reinforcement 30 at the bottom of the stirrup, which greatly improves the efficiency of the insertion and laying of the longitudinal reinforcement 30.

[0098] Two conveying wheels 41 are arranged on each transmission shaft 47, and a roller 48 is arranged between the two conveying wheels 41, so that the transmission shaft 47 can control the rotation of the conveying wheel 41 and the roller 48 at the same time. The forward and reverse rotation of the transmission shaft 47 makes the conveying wheel 41 and the roller 48 run in staggered positions, thereby optimizing the construction process of threading and laying the reinforcement.

[0099] In this embodiment, the conveying wheel 41 is a V-shaped wheel, and the V-shaped wheel has a V-shaped angle, which makes it easier to transport the longitudinal reinforcement 30.

The lifting platform 52 is lifted and lowered relative to the main frame 51, and the vertical position of the longitudinal reinforcement 30 relative to the stirrups can be adjusted to fix the longitudinal reinforcement 30 at different positions of the stirrups; finally, the welding device 55 extends out of the lifting platform 52 and welds at the intersection of the longitudinal reinforcement 30 and the stirrups, so that the longitudinal reinforcement 30 and the stirrups are positioned and fixed with high precision; after the welding is completed, the welding equipment 5 moves along the stirrup frame 10 to the next workstation, and continues the above steps until the stirrups and the longitudinal reinforcement 30 on their sides are completely welded and fixed.

[0101] In this embodiment, the welding equipment 5 and the stirrup placing equipment 3 can share a set of walking tracks 331, wherein the length of the walking tracks 331 is greater than the length of the stirrup frame 10. After the stirrup placing equipment 3 completes the placement of the stirrups, it can retreat to the periphery of the stirrup frame 10, which is convenient for the movement of the welding equipment 5. This not only simplifies the structural components of the production line, but also ensures that the stirrup placing process and the welding process are smoothly connected and do not interfere with each other.

[0110] In one embodiment of the present application, the lifting plate in the secondary lifting device 45 and the longitudinal ribs 30 in the primary cache slot 43 are on the same plane. After a set number of longitudinal ribs 30 are cached in the primary cache slot 43, the secondary lifting device 45 drives the lifting plate to rise, and the lifting plate lifts up the multiple longitudinal ribs 30 in the primary cache slot 43. The multiple longitudinal ribs 30 slide into the secondary cache slot 44 under the action of the inclined top surface of the lifting plate.

[0111] In this embodiment, the first-stage lifting device 42 and the second-stage lifting device 45 may be air cylinders or oil cylinders.

In one embodiment of the present application, a V-shaped angle is formed between the lifting plate and the guide plate, and when the lifting plate rises to the top of the guide plate, the longitudinal rib 30 passes over the guide plate and falls into the cache slot, thereby ensuring the stable transportation and caching of the longitudinal rib 30 by the multi-level cache assembly.

In one embodiment of the present application, the length reader 46 can read the transmission length of the longitudinal reinforcement 30 on the conveying wheel 41. When the transmission length of the longitudinal reinforcement 30 reaches the set requirement, the conveying wheel 41 stops rotating, and the longitudinal reinforcement 30 on the conveying wheel 41 is transferred to the first-level buffer slot 43 for temporary storage by the first-level lifting device 42.

[0115] In other embodiments, a driving pulley may be provided at the output end of the driving motor, and a driven pulley may be provided at one end of the transmission shaft 47, and the driving pulley and the plurality of driven pulleys may be connected via a belt transmission.

[0116] The roller 48 is a hollow cylindrical structure, which is sleeved on the outer periphery of the transmission shaft 47. An elastic pawl is provided on the inner wall of the roller 48. A ratchet is provided on the transmission shaft 47, and the ratchet cooperates with the elastic pawl in a rotational direction.

[0117] In one embodiment of the present application, when the transmission shaft 47 rotates forward, the transmission shaft 47 drives the conveying wheel 41 to rotate forward, and the conveying wheel 41 transmits the longitudinal reinforcement 30 downstream. At this time, the ratchet on the transmission shaft 47 and the elastic ratchet on the roller 48 do not transmit; when the transmission shaft 47 reverses, the transmission shaft 47 drives the conveying wheel 41 to reverse. At this time, there is no longitudinal reinforcement 30 on the conveying wheel 41, and there are multiple longitudinal reinforcements 30 on the roller 48. The ratchet on the transmission shaft 47 and the elastic ratchet on the roller 48 cooperate with each other in transmission, so that the transmission shaft 47 drives the roller 48 to rotate, and the roller 48 drives the longitudinal reinforcement 30 to move upstream to pass the longitudinal reinforcement 30 into the bottom of the stirrup.

[0118] The side cloth method includes the following steps:

[0119] Step 1: Two straightening and cutting machines 40 at one end of the stirrup frame 10 straighten and cut the longitudinal reinforcement 30 and feed them to the conveying wheels 41 at both sides of the stirrup frame 10;

[0120] Step 2, the transmission shaft 47 drives the conveying wheel 41 to rotate forward to convey the longitudinal reinforcement 30 to the downstream. When the longitudinal reinforcement 30 passes through the length reader 46, the length reader 46 records the conveying length of the longitudinal reinforcement 30. When the conveying length of the longitudinal reinforcement 30 reaches the set value, the conveying wheel 41 stops rotating;

[0121] Step 3, the first-level lifting device 42 drives the lifting plate to lift upward, so that the longitudinal ribs 30 on the conveying wheel 41 are cached in the first-level cache slot 43;

[0122] Step 4, repeating steps 1-3 until a set number of longitudinal ribs 30 are stored in the first-level cache slot 43;

[0123] Step 5: The secondary lifting device 45 drives the lifting plate to lift upward, so that the plurality of longitudinal bars 30 in the primary buffer slot 43 are cached in the secondary buffer slot 44;

[0126] The bottom reinforcement method includes the following steps:

[0127] Step 1, the bottom longitudinal reinforcement frame at the other end of the stirrup tire frame 10 transfers the bottom longitudinal reinforcement 30 to the roller 48. When the conveying wheel 41 completes the conveying of the longitudinal reinforcement 30 on the side of the stirrup, the transmission shaft 47 drives the roller 48 to reverse, so as to pass multiple first-section longitudinal reinforcements 30 to the bottom of the stirrup. After the first-section longitudinal reinforcement 30 is conveyed to the specified position, the first-section longitudinal reinforcement 30 is manually connected with the second-section longitudinal reinforcement 30. In this embodiment, the conveying of the bottom longitudinal reinforcement 30 can be carried out after the unloading, conveying and caching of the longitudinal reinforcement 30 in the side laying method are completed, thereby saving more time and facilitating improving construction efficiency.

[0128] In this embodiment, a plurality of sections of bottom longitudinal bars 30 are arranged on the bottom longitudinal bar penetration frame. The diameter of the bottom longitudinal bars 30 is larger than that of the side longitudinal bars 30. The bottom longitudinal bars 30 use thicker steel bars to ensure that the steel cage has sufficient strength. The bottom longitudinal bars 30 are divided into a multi-section structure. The bottom longitudinal bars 30 at adjacent ends are welded to each other. Such an arrangement can facilitate the penetration operation of the bottom longitudinal bars 30.

[0129] Step 2, when the first longitudinal reinforcement 30 is connected to the second longitudinal reinforcement 30, the unloading, conveying and caching of the longitudinal reinforcement 30 in the side material laying method are carried out synchronously; after the first longitudinal reinforcement 30 is connected to the second longitudinal reinforcement 30, the transmission shaft 47 drives the roller 48 to reverse, and continues to pass the second longitudinal reinforcement 30 to the bottom of the stirrup until the second longitudinal reinforcement 30 is delivered to the right position;

[0130] Step 3, repeat steps 1-2 until all the bottom longitudinal reinforcements 30 are threaded.

[0131] In this embodiment, the process of threading the bottom longitudinal ribs 30 and the process of laying the side longitudinal ribs 30 can be staggered by utilizing the gap time between the transmissions of the two, so that the same transmission shaft 47 can simultaneously control the rotation of the conveying wheel 41 and the roller 48. The forward and reverse rotations of the transmission shaft 47 can make the conveying wheel 41 and the roller 48 run in staggered order, thereby optimizing the construction process of laying the side longitudinal ribs 30 and threading the bottom longitudinal ribs 30, thereby greatly improving the construction efficiency and reducing the construction cost.

[0150] Step 2, after the bending and welding of the stirrups are completed, the stirrups are placed on the stirrup transfer rack in a set order; in this embodiment, a robot is provided on one side of the stirrup bending and forming machine 2, and the stirrups are grabbed and placed on the stirrup transfer rack by the robot. A plurality of slots are also provided on the stirrup transfer rack, and the slots are used to position the stirrups to meet the spacing and verticality requirements of the stirrups.

[0151] Step 3, the stirrup transfer frame is driven by the AGV trolley to move to the inside of the stirrup placement device 3, so that the stirrup transfer frame and a part of the stirrup tire frame 10 are both located side by side inside the running frame;

[0152] Step 4, the Z-axis walking mechanism 35 moves downward from above the stirrup transport frame, and then the correction unit 32 straightens the stirrup, and the clamping unit 31 clamps the stirrup; then the Z-axis walking mechanism 35 drives the stirrup to move upward, so that the stirrup is separated from the stirrup transport frame; then the Y-axis walking mechanism 34 drives the Z-axis walking mechanism 35 to move to above the stirrup tire frame 10, the Z-axis walking mechanism 35 falls, and the clamping unit 31 releases the stirrup to the stirrup tire frame 10, so that a group of stirrups are placed on the stirrup tire frame 10;

After the first-section longitudinal reinforcement 30 stops conveying, the first-section longitudinal reinforcement 30 is manually connected with the second-section longitudinal reinforcement 30. In this embodiment, the transmission of the bottom longitudinal reinforcement 30 can be completed after the longitudinal reinforcement 30 is unloaded, conveyed and cached in the side laying method. The process is carried out in such a way as to save time and improve construction efficiency.
