Description

Technical Field

[0001] The invention relates to the field of steel bar bundling, in particular to a steel bar bundling device in a narrow space. Background Art

[0002] In construction projects, it is necessary to use steel bars that are crisscrossed and tied into a grid shape and then pour concrete to form a solid reinforced concrete structure. The intersection nodes of these steel bar grids must be tied and fixed with wire.

[0003] When tying steel mesh, a manual handheld steel tying machine is generally used to tie the steel at the tying location. The steel tying machine is an intelligent tool with a built-in microcontroller that can automatically complete all the steps of steel tying. It can be widely used in the field of construction engineering to replace manual tying of steel bars. The steel tying machine is mainly composed of a machine body, a special wire reel, a battery box and a charger. However, the traditional steel tying machine and steel tying method have the following problems: When bundling, for the plane grid formed by the staggered steel bars, a manual handheld bundling machine is used to bundle the intersections of the steel mesh at one time. Since the manual bundling is performed one by one, a lot of processing time will be wasted. When bundling the steel cage formed by the criss-crossing steel bars, one or more sides of the steel cage may be blocked by buildings. For example, when building a basement, the load-bearing wall of the basement will be set from the side wall of the foundation pit edge, and the load-bearing wall steel cage needs to be tied. However, since the steel cage is close to the side wall of the foundation pit edge, the space is relatively narrow, which is not conducive to the construction of the bundling personnel. In addition, since the space inside the steel cage is relatively small, the bundling personnel cannot enter the steel cage to perform the bundling work. At the same time, due to The obstruction of the building (the side wall of the foundation pit) makes it impossible for the construction workers to change their relative position to the steel cage, and thus it is impossible to bundle the surface of the steel cage blocked by the building. A bundling robot is needed to bundle from the inside of the steel cage. For different construction sites, the steel mesh composed of steel bars is of different sizes, so the distances between the intersections are different. When the bundling machine installed by the bundling robot (application document of patent number 202210965397.2) is working, it is impossible to adjust the relative position between the bundling machine and the robot, resulting in the bundling machine being unable to bundle multiple steel bar intersections located on the same horizontal line, thereby increasing the time and effort required for steel bar bundling. Therefore, a steel bar bundling device suitable for narrow spaces is proposed. Summary of the invention

[0031] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0032] Example 1

[0033] During construction, bottom reinforcement is generally laid and then tied. After tying, formwork is laid on the bottom reinforcement, and then upper reinforcement is laid and then tied. When tying, manual tying is mostly used, which is relatively inefficient.

[0034] Therefore, in view of the above situation, when tying the steel cage, this embodiment provides a steel bar tying device in a narrow space, please refer to Figure 1-12 ,include: Two cross beams 1 3 and two cross beams 2 5, two ends of the two cross beams 2 5 are respectively fixedly connected to the two ends of the two cross beams 1 3, wherein the two cross beams 1 3 and the two cross beams 2 5 can form a quadrilateral frame after being connected.

[0035] Motor 1, motor 1 is fixedly installed on the side where the two cross beams 2 5 are away from each other, track 1 2 is installed on the side where the two cross beams 2 5 are away from each other through the rotation of motor 1, and a displacement device for changing the position of the bundling device is arranged between the two cross beams 2 5. The power output ends of the two motors 1 are respectively connected to the active rollers of the two track 1 2. When it is necessary to bundle the grid-shaped steel bars, the cross beam 1 3 and the cross beam 2 5 are placed on the grid-shaped steel bars until the bottoms of the two track 1 2 are in contact with two parallel steel bars at the same time.

[0036] When the motor 1 is started, the active roller rotates along with the power output end of the motor 1, so that a plurality of driven rollers rotate accordingly under the action of the tension belt, so that the crawler 1 2 can move stably along the laying direction of the steel bars.

[0037] The vertical plate 10 is arranged between the two cross beams 5, and its two ends are fixedly connected to the adjacent sides of the two cross beams 5 respectively. The long end of the vertical plate 10 is fixedly connected to the adjacent sides of the two cross beams 5, and the two cross beams 5 support the vertical plate 10.

[0038] A receiving groove is provided on one side of the vertical plate 10, and a spring telescopic plate 19 is slidably installed in the inner cavity of the receiving groove through threaded drive. The receiving groove can limit the sliding trajectory of the spring telescopic plate 19, allowing the spring telescopic plate 19 to move back and forth along the left and right directions of the receiving groove, thereby preventing the spring telescopic plate 19 from being offset when moving back and forth.

[0039] A bundling device for bundling steel bars is provided on one side of the telescopic end of the spring telescopic plate 19 close to the accommodating groove, a connecting rod 18 is fixedly installed on one side of the telescopic end of the spring telescopic plate 19, one side of the shell 6 is fixedly connected to an end of the connecting rod 18 away from the spring telescopic plate 19, and the connecting rod 18 is set to an L-shaped structure. The connecting rod 18 can be used as a connecting piece between the spring telescopic plate 19 and the shell 6, so that the shell 6 can move along the laying direction of the steel bars with the crawler 2, and at the same time, the bottom of the shell 6 is parallel to the top of the beam 1 3 and the beam 2 5.

[0040] The spring telescopic plate 19 is composed of two slides of different sizes and multiple springs. A slide groove is provided at one end of the larger slide. One end of the smaller slide is slidably inserted into the slide groove, and the other end extends to the outside of the slide groove. The multiple springs are located between the bottom of the slide groove and the smaller slide groove and are interconnected with the bottom of the slide groove and the smaller slide groove. The multiple springs can apply thrust to the smaller slide groove and allow the smaller slide groove to quickly reset after moving into the slide groove.

[0041] When the shell 6 moves to the intersection of the steel bars, the spring telescopic plate 19 is pushed to move the shell 6 to the top of the intersection of the steel bars, and then the top of the spring telescopic plate 19 is pressed. At this time, the connecting rod 18 moves down with the telescopic end of the spring telescopic plate 19 until the bottom of the shell 6 is a certain distance away from the top of the intersection of the steel bars. The bundling equipment inside the shell 6 is started to bundle the intersection of the steel bars. After that, after the pressure on the telescopic end of the spring telescopic plate 19 is removed, the shell 6 is reset together with the telescopic end of the spring telescopic plate 19, and the bundling operation of a steel bar intersection can be completed.

[0042] The sliding groove is opened at the top of the vertical plate 10 and is interconnected with the inner cavity of the accommodating groove. A push plate 8 is slidably installed in the inner cavity. The sliding groove allows the push plate 8 to slide up and down in the inner cavity of the accommodating groove along the vertical direction, and the sliding trajectory of the push plate 8 can also be limited.

[0043] A slide groove 1 is opened in the middle of one side of the pushing plate 8 along the vertical direction, and a plurality of slide grooves 2 9 are opened on one side of the pushing plate 8 with the slide groove 1 as the midpoint. A plurality of slide grooves 2 9 are opened on one side of the pushing plate 8 with the slide groove 1 as the midpoint, and the distance between the bottom centers of two adjacent slide grooves 2 9 is the same.

[0044] The plurality of second slide grooves 9 are all arranged to be inclined in a direction away from the first slide groove, and the inclination angles of the second slide grooves 9 which are sequentially away from the first slide groove gradually increase.

[0045] The inner cavities of the slide groove 1 and multiple slide grooves 2 9 are slidably installed with sliding rods, and the end of the sliding rod close to the open end of the accommodating groove is fixedly installed with a pressure block 7 for pressing the telescopic end of the spring telescopic plate 19, and the inner wall of the accommodating groove away from the open end is fixedly installed with a guide rail 27, and the end of the sliding rod away from the pressure block 7 is fixedly installed with a slider compatible with the guide rail 27. When the push plate 8 is pressed, the side wall of the slide groove 2 9 presses the outer wall of the sliding rod, and with the relative sliding between the slide groove 2 9 and the sliding rod, multiple sliders slide synchronously along the guide rail 27 and move the same distance. When the pushing plate 8 is completed, the spacing between the multiple pressure blocks 7 is the same, and the distance between two adjacent pressure blocks 7 is precisely controlled by changing the up and down movement distance of the pushing plate 8.

[0046] The two adjacent sides of the pressure block 7 and the sliding rod are inclined away from their bottoms, the top of the telescopic end of the spring telescopic plate 19 is bent, and the top of the spring telescopic plate 19 is arched. The push plate 8 is pressed according to the distance between two adjacent steel bars until the distance between the middle parts of the bottom ends of the two adjacent pressure blocks 7 is the same as the distance between the two adjacent steel bars, and at the same time, the middle parts of the bottom ends of the multiple pressure blocks 7 and the middle parts of the steel bars are on the same horizontal line, and the pressing or upward movement of the push plate 8 is stopped, and then the moved push plate 8 is fixed, and then the spring telescopic plate 19 is pushed. When the curved surface of the spring telescopic plate 19 is aligned with the pressure plate 8, the pressure plate 8 is pressed. When the inclined surface of block 7 fits, the top of the spring telescopic plate 19 is forced to move downward, while ensuring the normal movement of the spring telescopic plate 19, until the top of the spring telescopic plate 19 is completely under the pressure block 7. At this time, the shell 6 moves horizontally to the top of the intersection of the steel bars and moves downward to a position where the steel bars can be tied. The position of the intersection of the shell 6 and the steel bars can be accurately controlled by controlling the distance between adjacent pressure blocks 7. When the shell 6 moves horizontally along the accommodating groove, it is beneficial to bundle multiple steel bar intersections on the same horizontal line in sequence, reducing the time and effort required for steel bar tying.

[0047] The hydraulic cylinder 23 is fixedly connected to the side of the vertical plate 10 away from the opening end of the accommodating groove, and the power output end is fixedly connected to one side of the push plate 8. When the hydraulic cylinder 23 is started, the push plate 8 moves up and down with the power output end of the hydraulic cylinder 23 and can position the pushed plate 8 after movement to prevent displacement when the bottom of the pressure block 7 contacts the top of the spring expansion plate 19, so that the shell 6 can be accurately moved down to the bundling position, so that multiple steel bar intersections located on the same horizontal line can be orderly bundled according to the moving distance of the shell 6.

[0048] Furthermore, when the spring telescopic plate 19 moves between two adjacent pressure blocks 7, the telescopic end of the spring telescopic plate 19 moves upward, thereby restoring the shell 6, which is beneficial for the crawler track 2 to move again.

[0049] Two through holes are provided on one side of the big head end of the spring telescopic plate 19, and a spiral groove is provided on the inner wall of one of the through holes. A driving threaded rod 21 is installed inside the through hole with the spiral groove through threaded cooperation. Both ends of the driving threaded rod 21 pass through the through holes and are rotatably connected to the inner wall of the accommodating groove. A motor 2 for driving the threaded rod 21 to rotate is fixedly installed on the outside of the vertical plate 10. A hole matched with the driving threaded rod 21 is provided on one side of the vertical plate 10, and one end of the driving threaded rod 21 passes through the hole and extends to the outside of the accommodating groove. The power output end of the motor 2 is connected to the end of the driving threaded rod 21 extending to the outside of the accommodating groove through a chain. After the motor 2 is started, the threaded rod 21 is driven to rotate under the action of the chain. Under the cooperation of the spiral groove, the spring telescopic plate 19 slides along the axial direction of the driving threaded rod 21, and the moved spring telescopic plate 19 is positioned under the cooperation of the thread, thereby improving the stability of the spring telescopic plate 19 in a static state.

[0050] Furthermore, motor 2 (a driving motor controls the rotation direction of its own rotor through an H-bridge circuit. The H-bridge circuit is the most common method for controlling the direction of a DC motor. It is composed of four switches (usually transistors or relays). These switches can control the direction of current flow at both ends of the motor. When the current flows to the motor from one direction, the motor rotates in one direction. When the current direction changes, the motor rotates in the opposite direction. By alternately changing the direction of the current, the reciprocating motion of the motor can be achieved.) can change the rotation direction of its own power output end through a lower current, thereby adjusting the rotation direction of the driving threaded rod 21.

[0051] A guide rod 20 is arranged in the inner cavity of another through hole, and both ends of the guide rod 20 pass through the through hole and are fixedly connected to the inner wall of the accommodating groove. When the spring telescopic plate 19 moves back and forth, its own sliding trajectory can be limited by the cooperation of the guide rod 20 and the through hole, thereby preventing the spring telescopic plate 19 from rotating with the driving threaded rod 21 and shaking and tilting during the sliding process, thereby improving the sliding stability of the spring telescopic plate 19.

[0052] The bundling equipment includes a shell 6, and a discharge trough connected to its own inner cavity is provided at the bottom of the shell 6, and a bending plate 38 is fixedly installed on one side of the discharge trough, wherein one end of the bending plate 38 is fixedly connected to one side of the inner cavity of the discharge trough, and the bending plate 38 is arranged as an arch structure, and a gap formed between the other end of the bending plate 38 and one side of the inner cavity of the discharge trough can allow the free end of the wire to pass through.

[0053] A guide plate 22 for guiding the iron wire is installed on one side of the bottom of the shell 6 through a torsion spring. The guide plate 22 is located directly below the gap formed by the bending plate 38 and the discharge chute. The guide plate 22 is bent and extends away from the end connected to the bottom of the shell 6 toward the bending plate 38.

[0054] The bottom of the bending plate 38 is provided with a bending groove for bending the iron wire, and the top of the bending plate 38 is provided with a through-slot connected to the bottom of the bending plate 38. After the shell 6 moves down to the side of the guide plate 22 located at the intersection of the steel bars, the free end of the iron wire enters the interior of the shell 6 and quickly moves to the bottom of the shell 6 through the gap between the bending plate 38 and the other side of the inner cavity of the bending groove until the free end contacts the curved surface of the guide plate 22. The free end of the iron wire moves along the curved surface of the guide plate 22 under continuous push. When the free end of the iron wire collides with the curved surface of the guide plate 22, it slides along the curved surface of the guide plate 22. The iron wire moving along the curved surface of the guide plate 22 is bent and deformed and continuously moves toward the direction of the bending plate 38 until the free end of the iron wire enters the interior of the bending groove and continuously moves inside the bending groove to form a spiral structure. At this time, the iron wire with a spiral structure is wrapped around the outside of the intersection of the iron wires.

[0055] Furthermore, when the curved surface of the spring expansion plate 19 is in contact with the outer wall of the pressure block 7 and moves downward, the bottom of the shell 6 continues to approach the steel bar. When the shell 6 moves downward to a certain extent (the top of the spring expansion plate 19 is not in contact with the bottom of the pressure block 7), the bottom of the guide plate 22 extends to the bottom of the steel bar. As the shell 6 continues to move, the outer wall of the guide plate 22 contacts the outer wall of the steel bar and the top rotates through the torsion spring until the bottom of the guide plate 22 rotates to just above the steel bar. When the top of the spring expansion plate 19 and the bottom of the pressure block 7 are in contact, the bottom of the guide plate 22 rotates across the top of the steel bar and moves to the other side, preventing the extension of the guide plate 22 from adversely affecting the normal movement of the shell 6, while ensuring the normal bending of the wire by the guide plate 22.

[0056] A cutting frame 14 is fixedly installed on one side of the inner cavity of the shell 6, and the cutting frame 14 is located directly below the guide roller 1 35 and the guide roller 2 36, and a hydraulic cylinder 4 1 is fixedly installed on one side of the inner cavity of the cutting frame 14, and a cutting blade 33 for cutting the iron wire is fixedly installed at the power output end of the hydraulic cylinder 4 1. Before the free end of the iron wire enters the gap formed between the guide plate 22 and the bending plate 38, it first passes through the chamber formed between the side wall of the cutting frame 14 and the cutting blade 33 until the iron wire is bent into a spiral structure. After the hydraulic cylinder 4 1 is started, the cutting blade 33 approaches the iron wire along the power output end until the tip of the cutting blade 33 and the inner wall of the cutting frame 14 press on the outer surface of the iron wire to achieve cutting of the iron wire.

[0057] When the steel bar intersection is tied, the hydraulic cylinder 2 41 is started again to quickly reset the mounting plate 39. At this time, the knotting plate 37 is pulled out from the inside of the wound steel bar and reset to facilitate the second winding of the steel bar.

[0058] A bearing block 42 is fixedly installed on the inner wall of the shell 6, and a motor 2 is fixedly installed on one end of the bearing block 42 close to the through slot, and a cross block 40 is fixedly installed on the power output end of the motor 2. A mounting plate 39 is provided at the bottom of the cross block 40, and a groove matching the cross block 40 is provided on the top of the mounting plate 39, wherein the groove is arranged in a cross-shaped structure. When the power output end of the motor 2 rotates, the cross block 40 rotates accordingly, and the matching mounting plate 39 in the groove rotates accordingly.

[0059] The bottom of the mounting disk 39 is symmetrically provided with knotting plates 37 in a circular distribution, and hydraulic cylinders 41 are symmetrically provided on both sides of the bearing block 42. The power output end of the hydraulic cylinder 41 is fixedly provided with a connecting plate rotatably connected to the outer wall of the mounting disk 39. The mounting disk 39 is located directly above the through-slot. When the iron wire forms a spiral structure under the action of the bending groove and is cut by the cutting blade 33, the hydraulic cylinder 41 is started to move the power output end toward the through-slot until one end of the two knotting plates 37 away from the mounting disk 39 passes through the through-slot and extends to directly below the bending plate 38. At this time, the iron wire bent into a spiral shape is located between the two knotting plates 37. Then, starting the motor 2 can allow the knotting plate 37 to rotate with the mounting disk 39, thereby twisting the iron wire bent into a spiral shape to allow it to be wrapped around the outside of the intersection of the steel bars, thereby achieving bundling of the intersection of the steel bars.

[0060] A guide roller 1 35 and a guide roller 2 36 for guiding the wire are rotatably installed on one side of the inner cavity of the shell 6. The outer walls of the guide roller 1 35 and the guide roller 2 36 fit each other. When the guide roller 2 36 rotates, the guide roller 1 35 rotates in the opposite direction under the action of friction, so as to facilitate the synchronous rotation of the guide roller 1 35 and the guide roller 2 36.

[0061] The outer walls of guide roller 1 35 and guide roller 2 36 are both provided with annular grooves adapted to the iron wire. After the iron wire is inserted into the shell 6, the free end of the iron wire passes through between guide roller 1 35 and guide roller 2 36, and the outer surface is tightly fitted with the inner wall of the annular groove. When guide roller 1 35 and guide roller 2 36 rotate, they move quickly and stably to the inside of the cutting frame 14 under the action of friction.

[0062] Furthermore, a plurality of sets of guide rollers 35 and 36 are installed in a straight line distribution and rotation in the inner cavity of the shell 6, which is beneficial to continuously limit the moving trajectory of the wire, prevent the free end of the wire from being offset when moving and unable to penetrate the interior of the cutting frame 14, and improve the stability of the free end of the wire penetrating the interior of the cutting frame 14.

[0063] Guide roller one 35 and guide roller two 36 are located directly above the gap formed by the bending plate 38 and the discharge chute, and a motor three for rotating guide roller two 36 is fixedly installed on the outer wall of the shell 6, wherein a plurality of holes are opened on the outside of the shell 6, and one end of the guide roller two 36 closest to the cutting frame 14 passes through the hole and extends to the outside of the shell 6, and the power output end of the motor three and the end of the guide roller two 36 extending to the outside of the shell 6 are connected by a chain, and when the motor three is started, the plurality of guide rollers two 36 rotate accordingly, thereby providing power for the movement of the iron wire.

[0064] A bearing plate 17 is fixedly installed on one side of the telescopic end of the spring telescopic plate 19, and a limiting groove is provided on the side of the bearing plate 17 away from the spring telescopic plate 19. A support bar 15 is slidably installed in the inner cavity of the limiting groove. The support bar 15 is located directly below the connecting rod 18. The limiting groove can limit the sliding trajectory of the support bar 15 to prevent the support bar 15 from shaking and deflecting when moving, thereby improving the stability of the support bar 15 when moving.

[0065] A threaded hole is provided on the side wall of one end of the support bar 15 located in the inner cavity of the limiting groove, and a transmission threaded rod 16 is arranged in the inner cavity of the threaded hole. Both ends of the transmission threaded rod 16 pass through the threaded holes and are rotatably connected to the inner wall of the limiting groove. A motor 4 for rotating the transmission threaded rod 16 is fixedly installed on the outer wall of the supporting plate 17. An adapter hole matching the transmission threaded rod 16 is provided at one end of the supporting plate 17. One end of the supporting plate 17 passes through the adapter hole and extends to the outside of the supporting plate 17. The power output end of the motor 4 is connected to one end of the transmission threaded rod 16 extending to the outside of the supporting plate 17 through a chain drive. After the power output end of the motor 4 rotates, the transmission threaded rod 16 rotates accordingly, and the support bar 15 moves along the limiting groove with the cooperation of the threaded hole.

[0066] As the guide roller 2 36 rotates, the iron wire wrapped around the outside of the unwinding drum 4 continuously enters the interior of the shell 6, and as a result, the iron wire on the outer surface of the unwinding drum 4 continuously moves away from the through hole, and then the motor 4 is started to rotate the transmission threaded rod 16, so that the unwinding drum 4 moves continuously toward the through hole along with the support bar 15, effectively reducing the distance between the steel wire wrapped on the outer surface of the unwinding drum 4 and the through hole as it continuously enters the interior of the shell 6, thereby avoiding bending and jamming of the steel wire when entering the shell 6 through the through hole.

[0067] Furthermore, the motor four and the motor two are of the same model, and the rotation direction of the power output end of the motor four can be changed by alternating current, which is beneficial to changing the moving direction of the support bar 15 and positioning the support bar 15 after movement.

[0068] A mounting rod 13 is rotatably mounted on the side wall of the other end of the support bar 15, and a reel 4 is movably sleeved on the outer wall of the mounting rod 13. The outer wall of the reel 4 is evenly wound with wire for bundling the intersection of the steel bars. The reel 4 is a cylindrical structure with more wire wound around it. When tying steel bars in a narrow space, the number of times the wire is replaced can be reduced. A through hole matching the wire is provided on the side of the shell 6 close to the reel 4, and multiple sets of guide rollers 35 and 36 are installed on the outer wall of the shell 6. The middle of the open end of the through hole and the guide rollers 35 and 36 are on the same horizontal line. The free end of the wire outside the reel 4 is inserted between the guide rollers 35 and 36 outside the shell 6, and the free end of the wire passes through the through hole and enters the inside of the shell 6.

[0069] A turning plate 34 for changing the moving direction of the iron wire is fixedly installed on one side of the inner cavity of the shell 6. The turning plate 34 is set to an L-shaped structure, and the corner of the turning plate 34 is bent. One end of the iron wire entering the shell 6 contacts the bending part of the turning plate 34 and squeezes one end of the iron wire to make it bend toward the cutting frame 14, so that the inserted end of the iron wire is inserted between the guide roller 1 35 and the guide roller 2 36.

[0070] The outer wall of the mounting rod 13 is fixedly sleeved with a limit plate 47 for limiting the position of the unwinding drum 4, and a threaded groove is opened at one end of the mounting rod 13 away from the support bar 15, and a positioning pin 26 for positioning the unwinding drum 4 is installed in the inner cavity of the threaded groove through threaded cooperation. After the unwinding drum 4 is sleeved on the outside of the mounting rod 13, one end and one end of the limit plate 47 fit together, and then one end of the positioning pin 26 is inserted into the threaded groove, and then the positioning pin 26 is rotated to connect with one end of the mounting rod 13 under the cooperation of the threaded groove. At this time, one end of the positioning pin 26 and the other end of the unwinding drum 4 are tightly fitted and a continuous pressure is applied to the unwinding drum 4 to approach the limit plate 47. Under the dual extrusion of the limit plate 47 and the positioning pin 26, the unwinding drum 4 is fixed, and the unwinding drum 4 can be rotated together with the mounting rod 13.

[0071] In this embodiment, a load-bearing plate 12 is arranged between two adjacent cross beams 5, and a clamping plate 43 is slidably sleeved on the outer wall of the load-bearing plate 12. A spring telescopic plate 2 45 (having the same components and working principle as the spring telescopic plate 19) is fixedly installed on one side of the clamping plate 43. The top of the spring telescopic plate 2 45 is fixedly connected to the bottom of the load-bearing plate 17. When the telescopic end of the spring telescopic plate 19 moves up and down, the telescopic end of the spring telescopic plate 2 45 moves up and down accordingly. At the same time, the load-bearing plate 17 is supported under the action of the clamping plate 43, thereby improving the stability of the load-bearing plate 17 when it moves back and forth.

[0072] The inner wall of the clamping plate 43 is rotatably mounted with a load-bearing wheel 44 that fits with the outer wall of the load-bearing plate 12. The load-bearing wheel 44 can serve as a connecting medium between the inner wall of the clamping plate 43 and the outer wall of the load-bearing plate 12, and can effectively reduce the friction between the clamping plate 43 and the load-bearing plate 12 when it moves back and forth, thereby improving the smoothness of the unwinding disk 4 when it moves back and forth.

[0073] This embodiment is suitable for bundling steel bars laid parallel to the horizontal plane. Under the action of the overall self-gravity, the crawler track 1 2 can walk on the steel bar frame.

[0074] Example 2

[0075] When bundling the intersection of the cage-type steel mesh formed by the wall, the ground and the load-bearing column, not only the steel bars parallel to the horizontal line need to be bundled, but also the side of the cage-type steel mesh perpendicular to the horizontal plane needs to be bundled. When the crawler 2 is placed on the side wall of the cage-type steel mesh perpendicular to the horizontal plane, the center of gravity of the crawler 2 changes, and it falls under the action of gravity and separates from the outside of the cage-type steel mesh. Therefore, the cage-type steel mesh perpendicular to the horizontal plane cannot be bundled.

[0076] Therefore, when bundling the steel bar intersections in the above situation, please refer to Figure 1 , Figure 2 , Figure 3 and Fig.11 , further improvements made on the basis of Example 1: The elastic plate 46 is arranged in the inner cavity of the U-shaped plate 11, and one end of the elastic plate 46 is fixedly connected to one side of the inner cavity of the U-shaped plate 11. When the track 2 moves along the steel bar, the elastic plate 46 located at the rearmost end of the moving direction of the track 2 is separated from the steel bar, and at the same time, the elastic plate 46 located at the frontmost end of the moving direction of the track 2 is re-fitted with the outer surface of the steel bar under the action of gravity and the movement of the track 2, thereby improving the stability of the movement of the track 2.

[0077] The elastic plate 46 is set to a U-shaped structure, which can be tightly wrapped around the outer surface of the steel bar, effectively preventing the track 12 from falling when crawling along the steel bar perpendicular to the horizontal plane.

[0078] A slot is provided at the top of the U-shaped plate 11. When the track 2 passes through the intersection of the steel bars, the steel bars crossing it enter the slot, which effectively prevents the track 2 from moving to the intersection of the steel bars and contacting one end of the U-shaped plate 11 with the outer wall of the steel bars to generate a reverse force thereon, thereby causing the track 2 to separate from the outer surface of the steel bars.

[0079] The elastic plate 46 is made of metal springs, which can improve its own plastic deformation ability and extend the service life of the elastic plate 46.

[0080] In this embodiment, the push plate 8 is the highest structure of the device, and its height is 30-40 cm. When tying the vertical steel bars, the elastic plate 46 can be clamped with the vertically arranged steel bars, which can prevent the entire device from falling and complete the vertical steel bar tying. At the same time, because the overall structure is relatively short, it is also suitable for the construction of narrow gaps, especially when tying steel bars for the weighing wall of the basement, the device can be placed in the narrow space between the steel cage of the load-bearing wall and the side wall of the foundation pit to perform steel bar tying work.

[0081] Example 3

[0082] In this embodiment, it is also applicable to the steel bar bundling at the position of the post-casting belt. The post-casting belt is a gap structure set up to prevent harmful cracks that may be caused by uneven shrinkage or uneven settlement of reinforced concrete structures. Its overall width is 700mm-1000mm, and one is set every 30m-40m. The steel bars of the post-casting belt are set into two types: one is a through steel bar, and the other is a lap steel bar. For the lap steel bar, after the main concrete is poured, the steel bars of the post-casting belt are overlapped with the main steel bars on the steel bars reserved in the main body, and the steel bars are tied. The lap steel bars are mainly applicable to the settlement type post-casting belt.

[0083] Since the width of the post-casting strip is between 700mm-1000mm, its overall width is small, and coupled with the extension of the main steel bars, it is very inconvenient for workers to construct when the steel bars of the post-casting strip are overlapped. Therefore, this solution is also suitable for tying steel bars in the narrow space of the post-casting strip.

[0084] Due to the limitation of the reserved steel bars (bottom bars and upper bars) of the main body, the telescopic length of the hydraulic cylinder three cannot be too large, so as to prevent the push plate 8 or the overall structure from touching the upper bars. Therefore, the power output end of the hydraulic cylinder three is not easy to extend too long to prevent the device from colliding with the other side of the steel cage and affecting the extension of the power output end of the hydraulic cylinder 1 23, thereby hindering the adjustment of the push plate 8. At the same time, due to the clamping of the elastic plate 46 on the outside of the steel bar, it can prevent the crawler 1 2 from falling off when it moves in the direction perpendicular to the ground along the steel cage. Therefore, when adjusting the left and right positions of the crawler 1 2, the elastic plate 46 must not be completely separated from the steel bar, thereby making further improvements based on Example 2: The displacement device includes a U-shaped plate 11 and an elastic plate 46. A plurality of bases 48 are fixedly installed on the outer wall of the track 2. The base 48 is arranged as a "U-shaped structure". The U-shaped plate 11 is rotatably installed on the top of the base 48 through a torsion spring. A connecting block is fixedly installed on one end of the U-shaped plate 11. At the same time, rotating shafts are symmetrically arranged on both sides of the inner cavity of the base 48. A torsion spring connected to the inner wall of the base 48 is fixedly installed on the outer wall of the rotating shaft. The two sides of the connecting block are respectively fixedly connected to the adjacent ends of two adjacent rotating shafts. When the left and right sides of the U-shaped plate 11 are subjected to force, it rotates around the rotating shaft as the axis, and the torsion spring is compressed at the same time. When the force on the left and right sides of the U-shaped plate 11 disappears, it is reset to its own bottom and parallel to the outer wall of the track 2 together with the torsion spring.

[0085] The power output end of hydraulic cylinder three extends to just below the cross plate 25. A connecting plate is installed at the power output end of hydraulic cylinder three. Mounting frames 24 are symmetrically installed at both ends of the connecting plate. Tracks 29 are installed at the bottom of the two mounting frames 24. The driving wheels of the two tracks 29 are connected by a connecting rod.

[0086] A motor five for rotating the track two 29 is fixedly installed on one side of the mounting frame 24. The model of the motor five is the same as that of the motor two. The direction of rotation of the power output end of the motor five can be changed by changing the direction of the current. The power output end of the motor five is connected to one end of one of the driving wheels. When the motor five is started, the two driving wheels rotate synchronously under the action of the connecting rod, which is conducive to the synchronous rotation of the two track twos 29.

[0087] The outer wall of crawler track 29 is provided with a plurality of mounting grooves, an electromagnet 32 ​​is fixedly installed in the inner cavity of the mounting groove, a column 30 is fixedly installed on the side of the electromagnet 32 ​​close to the conveying roller of crawler track 29, a conductive block 31 is fixedly installed on the end of the column 30 away from the electromagnet 32, a conductive slide rail 28 for energizing the electromagnet 32 ​​is provided inside crawler track 29, a guide rail matching the conductive block 31 is installed at the bottom of the conductive slide rail 28 along the direction of rotation of crawler track 29, when crawler track 29 moves, the column 30 moves with crawler track 29 until the conductive block 31 enters the inside of the guide rail.

[0088] Furthermore, after the intersection of the steel bars that coincide with the moving trajectory of track 1 2 is tied, the hydraulic cylinder 3 is started and the conductive slide rail 28 is energized. At this time, the two track 29 moves downward under the action of the power output end of the hydraulic cylinder 3 and contacts the outside of the steel bars. As the power output end of the hydraulic cylinder 3 continues to move, the track 29 applies pressure to the outside of the steel bars. At the same time, the outer wall of the electromagnet 32 ​​located directly below the guide rail contacts the outer surface of the steel bars. At the same time, the steel bars apply a reverse force to the track 29, so that the track 1 2 is slightly lifted and separated from the steel bars.

[0089] When the power output end of the hydraulic cylinder 3 extends and the crawler 29 applies a reverse force to the outside of the steel bar, the steel bar inside the elastic plate 46 moves to between the elastic plate 46 and the end of the U-shaped plate 11 away from the crawler 1 2, and the elastic plate 46 can also be stuck with the steel bar and not separated. The specific needs are determined according to the rising height of the crawler 1 2 during actual use. In this embodiment, it is taken as an example that the elastic plate 46 and the steel bar do not separate when the crawler 1 2 rises.

[0090] The conductive block 31 located inside the guide rail contacts the inner wall of the guide rail and is energized. The current is transmitted to the electromagnet 32 ​​through the conductive block 31 and the column 30. The electromagnet 32 ​​is adsorbed on the outer surface of the steel bar after being energized. Under the dual effects of the elastic plate 46 and the adsorption force of the electromagnet 32, the device can be placed more stably on the vertical plane.

[0091] The rotation direction of crawler track 1 2 is perpendicular to that of crawler track 2 29. When crawler track 1 2 moves to the end of the steel mesh, hydraulic cylinder 3 is started. When crawler track 1 2 is slightly lifted, motor 5 is started to rotate crawler track 2 29. At this time, multiple conductive blocks 31 continuously enter and exit the guide rail. When the conductive blocks 31 are moved out of the guide rail, the electromagnet 32 ​​is powered off and the current disappears, which is conducive to the continuous rotation of crawler track 2 29. When crawler track 2 29 rotates, the entire structure follows the movement of crawler track 2 29. The movement direction is as follows: Fig.15 As shown by the middle arrow, since the elastic plate 46 and the U-shaped plate 11 are always connected with the steel bar, the U-shaped plate 11 rotates with the rotating shaft of the base 8 as the rotation center until the inner wall of the U-shaped plate 11 is completely separated from the steel bar, at which time the external force on the U-shaped plate 11 disappears, and the U-shaped plate 11 is reset under the action of the torsion spring. The elastic plate 46 and the U-shaped plate 11 can rotate in the direction of movement of the crawler 29. In the direction of movement of the crawler 29, the elastic plate 46 and the U-shaped plate 11 cannot rotate autonomously, so when the crawler 2 moves with the entire device, the elastic plate 46 and the U-shaped plate 11 can still clamp the steel bar.

[0092] As the crawler 29 continues to move horizontally, the outer wall of the U-shaped plate 11 repeatedly collides with the steel bars at different positions. When the crawler 29 moves to the outside of the steel bars at the predetermined position, following the direction of the main body movement, one side of the U-shaped plate 11 contacts the vertical steel bars, and then rotates with the rotating shaft of the base 48 as the rotation center, which will not hinder the horizontal movement of the entire device. After the U-shaped plate 11 is separated from the vertical steel bars, the U-shaped plate 11 returns to its original shape (i.e., in the direction perpendicular to the crawler 2) under the action of the torsion spring, and the U-shaped plate 11 contacts the upper part of the horizontally placed steel bars, which plays a supporting role for the entire device and can prevent the entire device from falling along the steel bars. When the crawler 29 moves horizontally with the entire device, the movement is more stable. It should be noted that: since there are multiple U-shaped plates 11, it is not required that all U-shaped plates 11 can contact the upper part of the horizontally placed steel bars. In principle, as long as there is a U-shaped plate 11 that contacts the upper part of the horizontally placed steel bars, it is sufficient. Of course, the more U-shaped plates 11 that are in contact with the transverse reinforcement, the better the support effect on the overall device; At the same time, because the U-shaped plate 11 is perpendicular to the track 1 2, the entire device also has an anti-falling function. This function does not require that the U-shaped plate 11 must contact the horizontal steel bars when the track 2 29 moves the entire device horizontally. When the conductive block 31 is not firmly adsorbed on the steel bars, the entire device will slide downward. When it slides to the point where the U-shaped plate 11 contacts the nearest horizontal steel bar, the contact between the U-shaped plate 11 and the horizontal steel bar limits the entire device, thereby preventing the entire device from falling.

[0093] The distance between the two ends of the driving wheel and the driven wheel constituting track 29 is greater than the diameter of the conductive block 31. At the same time, annular grooves are provided on the outer walls of the driving wheel and the driven wheel. When the conductive block 31 passes through the driving wheel and the driven wheel, it passes through the inside of the annular groove to prevent the outside of the conductive block 31 from contacting the driving wheel and the driven wheel, thereby preventing the two ends of track 29 from warping up when the conductive block 31 passes through the driving wheel and the driven wheel, thereby improving the smoothness of track 29 during movement.

[0094] Connecting plates rotatably connected to the outer wall of the driving wheel are fixedly installed on both sides of the conductive slide rail 28 , and the conductive slide rail 28 can be supported by the connecting plates so that the conductive slide rail 28 can be fixed inside the second track 29 .

[0095] While embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the invention, and that the scope of the invention is defined by the appended claims and their equivalents.
