Description

Technical Field

[0001] This application relates to the technical field of track slab production, and in particular to an intelligent binding device for making track slab reinforcement cages. Background Technology

[0002] Currently, as a key component of ballastless track, the track slab typically consists of a top layer of steel reinforcement mesh, a bottom layer of steel reinforcement mesh, and truss bars and stirrups connecting the two. The structure is complex and requires extremely high precision.

[0003] Existing automated equipment in related technologies typically includes automatic rebar feeding mechanisms, longitudinal and transverse rebar positioning mechanisms, and automatic binding robots. Their working principle is usually as follows: first, longitudinal and transverse rebars are transported to designated positions by servo motors, and then positioned and clamped by cylinders or hydraulic devices. Subsequently, the automatic binding head mounted on a gantry or robotic arm moves to the intersection point, feeds, winds, twists, and cuts the wire to complete the binding of one node.

[0004] The aforementioned technologies have the following drawbacks: when the binding head moves downwards and the binding point is being bound, the binding head and the reinforcing bar are rigidly connected. Therefore, a support structure is required to be placed under the reinforcing bar cage for support. However, most of the support structures are rigid and cannot level the reinforcing bar in time, resulting in a shift in the coordinate position of the reinforcing bar cage binding position. Summary of the Invention

[0005] To address the aforementioned technical issues, this application provides an intelligent binding device for fabricating and binding steel reinforcement cages for track slabs.

[0006] The intelligent binding equipment for fabricating and tying steel reinforcement cages for track slabs provided in this application adopts the following technical solution: An intelligent binding device for fabricating track slab reinforcement cages includes: A jig, used for making steel cages; The wire binding mechanism is used to bind the joints of the rebar cage. A lifting device for lifting rebars until tying is complete; and An image recognition system is used to identify the position of rebar tying and control the operation of the wire-tying mechanism; The lifting device includes: The support frame, with its lifting mechanism positioned at the bottom of the reinforcing steel bars; Support blocks are used to support reinforcing bars. A reciprocating motion mechanism is used to control the lifting and lowering of the support frame; and Phase change support mechanism, which uses phase change to level the steel bars and provide rigid support for them; The phase change support mechanism is used to connect the lifting block and the reciprocating motion mechanism; in the initial state, the steel bars are leveled by themselves, and when the phase change support mechanism changes to a solid state, it provides rigid support for the steel bar binding.

[0007] Furthermore, the phase change support mechanism includes: The support rod is fixedly connected to the bottom of the lifting block; Locking components, initially locking the support; and The deformation change component undergoes a shape change through a phase change, and the support rod is connected to the deformation change component; The locking component locks the support rod in the initial state, and disengages from the lock when the phase change component needs to start working.

[0008] Furthermore, the locking component includes: The locking block is slidably mounted on the bracket. The electromagnetic component attracts and fixes the support rod to the locking block via electromagnetic force; and The power unit is used to control the reciprocating motion of the locking block; In the initial state, the electromagnetic component is attracted and fixed to the support rod, and when the power unit starts to pull the locking block, the electromagnetic component pulls the locking block away.

[0009] Furthermore, the power unit includes: The lever, with its elastic rotation, is mounted on the bracket and its rotation position is close to the locking block; The power rope is fixedly connected at one end to the corresponding end of the lever and at the other end to the locking block; Phase change assembly controls lever rotation through phase change; and The recovery group, in conjunction with the phase change group, pulls the locking block back to its initial position.

[0010] Furthermore, the phase transition group includes: Shape memory alloy wires are fixedly connected to a support structure and undergo a phase change upon heating with the application of electricity; and The phase change block is fixedly connected to one end of the shape memory alloy wire and its movement is controlled. The phase change block is connected to the lever at one end near the power rope.

[0011] Furthermore, the deformation-changing component includes: The capsule is fixed to the support and located below the support rod; An electromagnetic coil generates a strong magnetic field around the capsule, causing the magnetorheological fluid inside the capsule to deform; and A support plate, with one end of a support rod passing through the support plate and extending into the cyst body; The support plate is fixedly connected to the surface of the capsule and also fixedly connected to the support rod.

[0012] Furthermore, the lever is provided with a flattening part at the end away from the phase change block, which is used to evenly distribute the magnetorheological fluid in the capsule.

[0013] Furthermore, the leveling section includes: The gravity rope is fixedly connected to the end of the lever furthest from the phase change block; Guide rollers are used to guide the gravity rope; A gravity block, connected to the end of a gravity rope, is used to strike the capsule, causing the magnetorheological fluid inside the capsule to flatten.

[0014] In summary, the beneficial technical effects of this application are as follows: 1. During the binding process, the reinforcing bars are subjected to rigid compression, while the reinforcing bars themselves are flexible. This can cause the position of the reinforcing bar to be bound to shift when the binding head comes into contact with the reinforcing bar. Therefore, it is necessary to support the reinforcing bar. The lifting device first provides flexible support to the reinforcing bar so that the reinforcing bar can level itself. Once the reinforcing bar is in position, it begins to provide rigid support to ensure that the position of the reinforcing bar to be bound does not shift during the binding process. 2. When the support rod is released, as the magnetorheological fluid inside the capsule is in its normal state, when the reinforcing bar is placed on the support block, the support rod and support plate compress the magnetorheological fluid inside the capsule, thereby achieving a leveling effect. After leveling is completed and binding is required, a strong magnetic field is generated on the magnetorheological fluid inside the capsule, at which point the magnetorheological fluid inside the capsule solidifies, achieving a hardening support effect on the reinforcing bar, thereby ensuring that the position of the reinforcing bar to be bound will not shift during the binding process; 3. In the initial state, the gravity block is located on the capsule. When the electromagnetic component on the locking block separates from the support rod, the gravity block separates from the capsule. After the support work is completed, the shape memory alloy wire has a short contraction time, so the lever swing action also occurs instantaneously. This allows the gravity block to quickly squeeze the capsule and quickly restore the distribution of the magnetorheological fluid inside the capsule. Attached Figure Description

[0017] The technical solutions of this application will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this application. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0018] This application discloses an intelligent binding device for fabricating and tying reinforcing cages for track slabs. (Refer to...) Figures 1-2 It includes a jig 1 for making a rebar cage; a wire binding mechanism for binding the rebar cage at the node position; a lifting device 2 for lifting the rebar until binding is completed; and an image recognition system for identifying the rebar binding position and controlling the wire binding mechanism. The jig 1 is used to place the rebar cage. Existing technologies usually also include an automatic rebar feeding mechanism, a longitudinal and transverse bar positioning mechanism, and an automatic binding robot. Its working principle is usually as follows: first, the longitudinal and transverse rebars are driven to the designated position by a servo motor, and then positioned and clamped by a cylinder or hydraulic device. Then, the image recognition system is used to identify the position where the rebar needs to be bound, and then the automatic binding head mounted on the gantry or robotic arm moves to the intersection point, feeds, winds, twists and cuts the wire to complete the binding of a node.

[0019] During the binding process, the reinforcing bars are subjected to rigid compression, while the reinforcing bars themselves are flexible. This can cause the position of the reinforcing bar to be bound to shift when the binding head comes into contact with the reinforcing bar. Therefore, it is necessary to support the reinforcing bar. The lifting device 2 first provides flexible support to the reinforcing bar so that the reinforcing bar can level itself. Once the reinforcing bar is in position, it begins to provide rigid support to ensure that the position of the reinforcing bar to be bound will not shift during the binding process. The lifting device 2 includes: a support 20, which is lifted and lowered at the bottom of the reinforcing bar; a lifting block 21, which supports the reinforcing bar; a reciprocating motion mechanism 22, which controls the lifting and lowering of the support 20; and a phase change support mechanism, which uses phase change to level the reinforcing bar and provide rigid support. The reciprocating motion mechanism 22 can be an electric actuator or a cylinder. Although the reciprocating motion mechanism 22 can adjust the position of the lifting block 21, it is a coarse adjustment. The phase change support mechanism is used to connect the lifting block 21 and the reciprocating motion mechanism 22. In the initial state, the reinforcing bar is leveled by itself. When the phase change support mechanism changes to a solid state, it provides rigid support for the reinforcing bar binding. The phase change support mechanism adjusts the level of the reinforcing bar flexibly and then provides rigid support for the reinforcing bar by changing its shape. Therefore, it ensures the accuracy and stability of the reinforcing bar binding position through intelligent means.

[0020] The phase change support mechanism includes: a support rod 23, which is fixedly connected to the bottom of the lifting block 21; a locking component, which locks the support in the initial state; and a deformation change component, which undergoes a shape change through phase change and is connected to the support rod 23. The locking component locks the support rod 23 in the initial state, and when the phase change component needs to start working, the locking component engages the lock on the support rod 23. That is, in the initial state, in order to ensure the stability of the lifting block 21, the support rod 23 is locked to the bracket 20 by the locking component, which facilitates the feeding of the steel bars. When the steel bars are stable, the locking component needs to be unlocked, and the deformation change component starts to work, which is the flexible leveling and subsequent rigid support.

[0021] The locking assembly includes: a locking block 24, slidably mounted on the bracket 20; an electromagnetic component 25, which attracts and fixes the support rod 23 to the locking block 24 via electromagnetic attraction; and a power unit for controlling the reciprocating motion of the locking block 24. Initially, the electromagnetic component 25 is attracted and fixed to the support rod 23. When the power unit begins to pull the locking block 24, the electromagnetic component 25 pulls the locking block 24 away. The direction in which the locking block 24 slides on the bracket 20 is perpendicular to the direction of movement of the support rod 23, i.e., the locking block 24 slides horizontally. The sliding method between the locking block 24 and the bracket 20 adopts the existing technology... In a conventional manner, the electromagnetic component 25 uses an electromagnet. When the electromagnet is energized, it attracts the support rod 23. When the electromagnet is de-energized, it releases the attraction to the support rod 23. Therefore, the locking block 24 is initially positioned where the electromagnet attracts the support rod 23. When it is necessary to adjust the position of the support rod 23, this embodiment needs to restrict the direction of movement of the support rod 23, that is, to ensure that the support rod 23 moves in a vertical direction. Therefore, in order to reduce the friction between the electromagnetic component 25 and the support rod 23, the power unit moves the electromagnetic component 25 away from the support rod 23.

[0022] The power unit includes: a lever 270, which is elastically rotatably mounted on the bracket 20 and rotates close to the locking block 24; a power rope 271, one end of which is fixedly connected to the corresponding end of the lever 270 and the other end of which is fixedly connected to the locking block 24; a phase change group, which controls the rotation of the lever 270 through phase change; and a return group, which works with the phase change group to pull the locking block 24 back to its initial position. The lever 270 is rotatably connected to the bracket 20 and connected to it by a torsion spring, thus achieving the effect of automatic reset of the lever 270. Of course, a steering roller can also be set on the bracket 20, and the power rope 271 changes direction through the steering roller. The power rope 271 remains taut throughout the process. The return group is set with multiple springs 26. The end of the locking block 24 is connected to the corresponding position of the bracket 20 by multiple springs 26. Therefore, the elastic force of the spring 26 is greater than the torsion force of the torsion spring, ensuring that the locking block 24 can return to its initial position.

[0023] The phase change assembly includes: a shape memory alloy wire 272, fixedly connected to the support 20 and undergoing a phase change upon heating by electricity; and a phase change block 273, fixedly connected to one end of the shape memory alloy wire 272 and controlling the pulling of the phase change block 273; the phase change block 273 is connected to the end of the lever 270 near the power rope 271. The shape memory alloy wire 272 is made of an iron-nickel alloy as used in the prior art. Therefore, when its phase change temperature is exceeded, the shape memory alloy wire 272 begins to undergo a phase change and begins to contract, thereby controlling the movement of the phase change block 273. In this embodiment, the phase change block 273 is designed as follows: A concave groove 274 is provided, and the corresponding end of the lever 270 is located in the concave groove 274. Therefore, as long as the phase change block 273 starts to move, the end of the lever 270 located in the concave groove 274 starts to swing, thus achieving the effect of controlling the swing of the lever 270. In this embodiment, it is only necessary to separate the electromagnetic component 25 from the support rod 23. Therefore, the required distance of movement is achieved. The power rope 271 is connected to the end of the lever 270 with the smaller swing position. Therefore, the power rope 271 can pull the locking block 24 and the electromagnetic component 25 away from the support rod 23.

[0024] After the locking of support rod 23 is released, the leveling of the reinforcing bar position begins. The deformation-changing components include: a capsule 280, fixed on bracket 20 and located below support rod 23; an electromagnetic coil 281, which generates a strong magnetic field around capsule 280, causing the magnetorheological fluid inside capsule 280 to deform; and a support plate 282, with one end of support rod 23 passing through support plate 282 and extending into capsule 280. Capsule 280 is made of a material with elastic properties and flexibility. Support plate 282 is fixedly connected to the surface of capsule 280 and also to support rod 23, providing a support fulcrum for support rod 23. The electromagnetic coil... 281 generates a strong magnetic field after being energized, which causes the magnetorheological fluid inside the capsule 280 to change its shape. The specific principle is based on the principle of existing technology, and the specific implementation will not be described in detail. When the magnetorheological fluid inside the capsule 280 is in its current state, the support rod 23 and the support plate squeeze the magnetorheological fluid inside the capsule 280 when the steel bar is placed on the support block 21, thereby achieving a leveling effect. After leveling is completed and binding is required, a strong magnetic field is generated on the magnetorheological fluid inside the capsule 280. At this time, the magnetorheological fluid inside the capsule 280 solidifies, achieving a hardening support effect on the steel bar, thereby ensuring that the position of the steel bar to be bound will not shift during the binding process.

[0025] The lever 270, at the end furthest from the phase change block 273, is also provided with a leveling section. This leveling section is used to evenly distribute the magnetorheological fluid within the capsule 280. When the magnetorheological fluid within the capsule 280 becomes fluid, since the support rod 23 and support plate have previously compressed the fluid, it is necessary to evenly distribute the fluid to ensure the support rod 23 and support plate can continue moving. The leveling section includes: a gravity rope 290, fixedly connected to the end of the lever 270 furthest from the phase change block 273; a guide roller 291 for guiding the gravity rope 290; and a gravity block. 292, connected to the end of gravity rope 290, and after being hammered on the capsule 280, the magnetorheological fluid inside the capsule 280 is flattened. Gravity block 292 is located above the side wall of capsule 280. In the initial state, gravity block 292 is located on capsule 280. When the electromagnetic component 25 on locking block 24 separates from support rod 23, gravity block 292 separates from capsule 280. After the support work is completed, due to the short contraction time of memory alloy wire 272, the swinging action of lever 270 also occurs instantaneously, which can realize that gravity block 292 can quickly squeeze capsule 280 and quickly restore the distribution of magnetorheological fluid inside capsule 280.

[0026] The implementation principle of the intelligent binding device for making track slab steel cages in this application embodiment is as follows: During the binding process, the steel bars are subjected to rigid compression, while the steel bars themselves are flexible. This may cause the position of the steel bar to be bound to shift when the binding head contacts the steel bar. Therefore, it is necessary to support the steel bar. The lifting device 2 first provides flexible support to the steel bar so that the steel bar can level itself. After the steel bar is in position, it begins to provide rigid support to ensure that the position of the steel bar to be bound will not shift during the binding process. When the locking of the support rod 23 is released, as the magnetorheological fluid inside the capsule 280 is in its normal state, when the reinforcing bar is placed on the support block 21, the support rod 23 and the support plate squeeze the magnetorheological fluid inside the capsule 280, thereby achieving a leveling effect. After leveling is completed and binding is required, a strong magnetic field is generated in the magnetorheological fluid inside the capsule 280. At this time, the magnetorheological fluid inside the capsule 280 solidifies, achieving a hardening support effect on the reinforcing bar, thereby ensuring that the position of the reinforcing bar to be bound will not shift during the binding process.

[0027] In the initial state, the gravity block 292 is located on the capsule 280. When the electromagnetic component 25 on the locking block 24 separates from the support rod 23, the gravity block 292 separates from the capsule 280. After the support work is completed, the shape memory alloy wire 272 has a short contraction time, so the lever 270 swings instantaneously. This allows the gravity block 292 to quickly squeeze the capsule 280 and quickly restore the distribution of the magnetorheological fluid inside the capsule 280.
