Description

Technical Field

[0001] The present invention relates to the technical field of steel bar processing, and particularly to a steel bar welded mesh bending device. Background Art

[0002] A steel bar welded mesh, also known as a welded steel bar mesh, a steel bar welded mesh, a steel bar welded mesh sheet, a steel bar mesh sheet, etc., is a mesh sheet in which longitudinal steel bars and transverse steel bars are arranged at a certain interval and are perpendicular to each other, and all intersection points are welded together. Steel bar meshes are widely used in the beam columns, floor slabs, roofs, walls of industrial and civil buildings, concrete pavements, bridge deck pavements, airport runways, tunnel linings, box culverts, wharf floors and other fields. Due to different application scenarios, steel bar welded meshes are usually processed into various shapes as prefabricated components.

[0003] An underground utility tunnel is an integrated underground urban pipeline corridor, that is, a tunnel space is built underground in the city, integrating various engineering pipelines such as electricity, communication, gas, heating, water supply and drainage, etc. It is equipped with special maintenance openings, hoisting openings and detection systems, and implements unified planning, unified design, unified construction and management. It is an important infrastructure to ensure the operation of the city. The construction of an underground utility tunnel requires a steel bar welded mesh corresponding to the cross-sectional shape of the underground utility tunnel as the steel structure in the reinforced concrete structure. For example, in the shape of a square tube, this requires bending a common steel bar welded mesh into a square tube structure.

[0004] The automation degree of existing steel bar welded mesh bending devices is still relatively low, and the adaptability is poor. The position of the mesh bending mechanism on the steel bar welded mesh bending device is usually fixed and cannot be moved, and can only meet the production requirements of specific product types. When the bending position changes, only other models of equipment can be replaced or the mesh bending mechanism can be disassembled and then installed at the required position. The disassembly and assembly are difficult, which is easy to damage the equipment and the production cost is relatively high; moreover, the number of mesh bending mechanisms on existing steel bar welded mesh bending devices is only one or two. When the length of the steel bar welded mesh to be processed and bent is relatively long and the bending positions are relatively many, the mesh bending mechanism needs to move frequently to change the bending position, wasting a lot of time and the production efficiency is extremely low.

[0075] To make the technical problems solved by the present invention, the technical solutions adopted and the achieved technical effects clearer, the technical solutions of the embodiments of the present invention will be further described in detail below with reference to the drawings. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative efforts shall fall within the protection scope of the present invention.

[0076] In the description of the present invention, unless otherwise clearly defined and limited, the terms "connected", "connected" and "fixed" should be understood in a broad sense. For example, it may be a fixed connection, a detachable connection, or integrated; it may be a mechanical connection or an electrical connection; it may be directly connected or indirectly connected through an intermediate medium, and it may be the internal communication of two components or the interaction relationship between two components. For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific situations.

[0077] In the present invention, unless otherwise clearly specified or limited, the first feature being "on" or "under" the second feature may include direct contact between the first and second features, or may include the first and second features not being in direct contact but being in contact through additional features therebetween. Moreover, the first feature being "above", "over" and "on top of" the second feature includes the first feature being directly above and obliquely above the second feature, or merely indicating that the horizontal height of the first feature is higher than that of the second feature. The first feature being "under", "beneath" and "underneath" the second feature includes the first feature being directly below and obliquely below the second feature, or merely indicating that the horizontal height of the first feature is less than that of the second feature.

[0078] In view of the problems in the prior art that the degree of automation of the steel bar welded mesh bending equipment is still relatively low, the adaptability is poor, the position of the mesh bending mechanism on the steel bar welded mesh bending equipment is usually fixed and immovable, and it can only meet the production requirements of specific product types, this embodiment provides a steel bar welded mesh bending equipment to solve the above technical problems.

[0079] As Figure 1 shown, the steel bar welded mesh bending equipment provided in this embodiment includes a bottom beam 1, a lifting platform unit 2 and a mesh bending unit 3.

[0080] The mesh bending unit 3 is used to bend the steel bar welded mesh. The mesh bending unit 3 is arranged to be movable on the bottom beam 1. By adjusting the position of the mesh bending unit 3 according to different bending positions of the steel bar welded mesh, the entire steel bar welded mesh can be bent and processed. Different types of steel bar welded meshes can also be processed by adjusting the position of the mesh bending unit 3, without the need to replace other models of equipment or disassemble the mesh bending unit 3, which is quick and convenient, improves the production efficiency and the applicable range of the steel bar welded mesh bending equipment, and reduces the production cost; multiple mesh bending units 3 can be arranged on the bottom beam 1 according to actual needs, so as to facilitate the processing of steel bar welded meshes with relatively long lengths or steel bar welded meshes with relatively many bending positions, and improve the production efficiency.

[0081] There are multiple lifting platform units 2, and the multiple lifting platform units 2 are arranged at intervals along the length direction of the bottom beam 1. The lifting platform unit 2 can rise to support the bent steel bar welded mesh. The mesh bending unit 3 can move across the lifting platform unit 2 in the descending state, and the lifting platform unit 2 will not interfere with the movement of the mesh bending unit 3. After the steel bar welded mesh is bent and the mesh bending unit 3 moves to the next position to be bent, in order to prevent the steel bar welded mesh from deforming due to its own weight sagging, the lifting platform unit 2 supports the bent steel bar welded mesh.

[0082] In this embodiment, the bottom beam 1 includes two bottom support beams arranged in parallel at intervals, and the two bottom support beams are connected by a transverse connecting beam. The lifting platform unit 2 is arranged between the two bottom support beams, and a plurality of lifting platform units 2 are arranged at intervals along the length direction of the bottom support beam. The bending net unit 3 is movably connected to the two bottom support beams.

[0083] Above the bottom support beam, a top beam is arranged in parallel. The top beam and the bottom support beam are connected by vertical beams to form a frame.

[0084] As Figure 2 shown, the bending net unit 3 in this embodiment includes a bending net frame 31. A traveling mechanism 32 is provided on the bending net frame 31. The traveling mechanism 32 can make the bending net frame 31 move relative to the bottom beam 1. A positioning mechanism 33 and a bending mechanism 34 are provided on the bending net frame 31. The positioning mechanism 33 is used to fix the steel bar welded mesh to be bent, and the bending mechanism 34 is used to bend the steel bar welded mesh and bend it to a preset angle.

[0085] Specifically, in combination with Figure 2 、 Figure 3 and Figure 4 shown, the bending net frame 31 includes a rectangular bottom support frame. The length direction of the support frame is perpendicular to the bottom support beam of the bottom beam 1. The traveling mechanism 32 includes traveling wheels 321 arranged on opposite sides of the bending net frame 31. A traveling track 11 matching the traveling wheels 321 is provided on the bottom beam 1. Specifically, traveling wheels 321 are provided on the sides of the four corners of the bending net frame 31. A traveling chute is recessed in the inner side wall of the bottom beam 1 to form a traveling track 11 matching the traveling wheels 321. The traveling wheels 321 are embedded in the traveling chute and can move along the traveling chute. Of course, in other embodiments, the traveling track 11 can also be provided on the upper surface of the bottom beam 1, and the traveling wheels 321 are slidably connected to the traveling track 11.

[0086] In order to realize the automatic traveling of the bending net unit 3, in this embodiment, referring to Figure 2 and Figure 5 shown, the traveling mechanism further includes a traveling drive assembly 322. The traveling drive assembly 322 drives the bending net frame 31 to move relative to the bottom beam 1.

[0087] Specifically, the travel drive assembly 322 includes a travel drive 3221, which is arranged on the bending net frame 31, and is specifically installed on the bottom support frame. The travel drive 3221 is connected to the travel shaft 3222, and the travel drive 3221 drives the travel shaft 3222 to rotate. The travel shaft 3222 extends along the length direction of the bottom support frame. The travel drive 3221 is preferably a dual-axis drive, and the travel drive 3221 is installed in the middle of the bottom support frame to avoid the problem of interference between the bending net unit 3 and other components when traveling. The two output ends of the travel drive 3221 are respectively connected to the first travel shaft and the second travel shaft.

[0088] Driving wheels 3223 are provided on opposite sides of the bending net frame 31, and the driving wheels 3223 are connected to both ends of the walking shaft 3222. Specifically, the other end of the first walking shaft and the other end of the second walking shaft are respectively connected to driving wheels 3223, and the walking driver 3221 drives the walking shaft 3222 to rotate, thereby driving the driving wheels 3223 to rotate. In order to facilitate the installation of the walking shaft 3222 and the driving wheels 3223, bending net bearing plates 311 are provided on opposite sides of the bottom support frame of the bending net frame 31, and the walking shaft 3222 is rotatably connected to the bending net bearing plate 311 and penetrates the bending net bearing plate 311 to be connected to the driving wheel 3223.

[0089] The driving wheel 3223 is meshed with a driven wheel 3224. Specifically, the driven wheel 3224 is rotatably mounted on the bending net bearing plate 311. A travel rack 3225 is provided on the bottom beam 1 and extends along the length direction of the bottom beam 1. The driven wheel 3224 is meshed with the travel rack 3225. The travel driver 3221 drives the bending net frame 31 through a gear rack structure, so that the bending net frame 31 moves along the travel track 11 on the bottom beam 1. In other embodiments, the transmission of driving force can also be achieved through a synchronous belt structure or a sprocket chain structure, so that the bending net frame 31 moves on the bottom beam 1.

[0090] The positioning mechanism 33 is used to fix the steel bar welded mesh to be bent, so as to prevent the steel bar welded mesh from being displaced when being bent, thereby affecting the bending accuracy. Figure 2 , Figure 6 , Figure 7 and Figure 8As shown in the figure, the positioning mechanism 33 includes a lifting roller 331, a clamping hand assembly 332, and a wire clamping seat 333. The clamping hand assembly 332 and the wire clamping seat 333 are both arranged below the lifting roller 331. The lifting roller 331 is used to support the reinforcing bar welded mesh to be bent. The clamping hand assembly 332 is used to clamp the longitudinal reinforcing bars of the reinforcing bar welded mesh. The wire clamping seat 333 is used to clamp the position to be bent of the longitudinal reinforcing bars of the reinforcing bar welded mesh. The longitudinal driving assembly 335 drives the clamping hand assembly 332 and the wire clamping seat 333 to move up and down. After the reinforcing bar welded mesh to be bent is placed on the lifting roller 331, the longitudinal driving assembly 335 drives the clamping hand assembly 332 and the wire clamping seat 333 to rise simultaneously, and the clamping hand assembly 332 clamps the longitudinal reinforcing bars of the reinforcing bar welded mesh. The transverse driving assembly 336 drives the wire clamping seat 333 to move horizontally to clamp the position to be bent of the longitudinal reinforcing bars of the reinforcing bar welded mesh. After the clamping hand assembly 332 clamps the longitudinal reinforcing bars of the reinforcing bar welded mesh, the wire clamping seat 333 clamps each longitudinal reinforcing bar, and the bending mechanism 34 bends the longitudinal reinforcing bars upward at the position clamped by the wire clamping seat 333. The wire clamping seat 333 plays a role in positioning and supporting the bending of the longitudinal reinforcing bars.

[0091] Further, a lifting roller support frame 313 is provided on the bottom support frame of the bending mesh frame 31, and the lifting roller 331 is installed on the lifting roller support frame 313. The longitudinal driving assembly 335 includes a longitudinal lifting beam 3351 and a longitudinal driver 3352. The clamping hand assembly 332 is fixedly arranged on the longitudinal lifting beam 3351, and the wire clamping seat 333 is horizontally slidably arranged on the longitudinal lifting beam 3351 to facilitate the wire clamping seat 333 to clamp the reinforcing bar welded mesh. The longitudinal driver 3352 drives the longitudinal lifting beam 3351 to move up and down. The clamping hand assembly 332 and the wire clamping seat 333 share one lifting device, which simplifies the structure of the bending mesh unit 3.

[0092] A longitudinal driver mounting frame 312 is provided on the bottom support frame of the bending mesh frame 31. The longitudinal driver 3352 is fixed to the longitudinal driver mounting frame 312, and the output end of the longitudinal driver 3352 is connected to the longitudinal lifting beam 3351. The longitudinal lifting beam 3351 includes a rectangular frame, and this rectangular frame is perpendicular to the bottom support frame of the bending mesh frame 31. The output end of the longitudinal driver 3352 is connected to the bottom border of the rectangular frame, and the clamping hand assembly 332 and the wire clamping seat 333 are respectively connected to the top border of the rectangular frame. The longitudinal driver 3352 is preferably a cylinder, the piston rod of the cylinder is arranged downward and is connected to the bottom border of the rectangular frame. When the piston rod of the cylinder extends, it drives the bottom support frame to descend, and when the piston rod of the cylinder retracts, it drives the bottom support frame to rise.

[0093] Since the longitudinal dimension of the longitudinal lifting beam 3351 is large, in order to improve the stability of the lifting of the longitudinal lifting beam 3351, in this embodiment, two longitudinal drivers 3352 are provided to drive the longitudinal lifting beam 3351 to move up and down.

[0094] In order to improve the stability of the vertical lifting beam 3351 during lifting, in this embodiment, a guiding structure is further provided. The guiding structure includes a guiding track 3353 and a guiding slider 3354. One of the guiding track 3353 and the guiding slider 3354 is provided on both sides of the vertical lifting beam 3351, and the other is provided on the lifting roller support frame 313.

[0095] In this embodiment, the gripper assembly 332 includes a plurality of grippers arranged side by side at intervals. The grippers are provided on one side of the lifting roller 331. Refer to Figure 9 As shown, each gripper includes a jaw 3321 and a jaw driver 3322 for driving the opening and closing of the jaw 3321. The jaw 3321 closes to clamp the longitudinal steel bars of the welded steel bar mesh.

[0096] Specifically, the jaw 3321 includes two jaw sub-parts. Each jaw sub-part includes a clamping portion and two V-shaped rod portions connected to the clamping portion and arranged at intervals. The V-shaped rod portions of the two jaw sub-parts are cross-arranged in an X shape. The middle parts of the two V-shaped rod portions of each jaw sub-part are connected by a limiting shaft to limit the opening angle of the two jaw sub-parts. Long strip holes are formed at the other ends of the V-shaped rod portions of each jaw sub-part, and the long strip holes extend along the length direction of the V-shaped rod portions. A driving shaft is passed through the long strip holes on the two jaw sub-parts to realize the connection of the two jaw sub-parts. The jaw driver 3322 is drivingly connected to the driving shaft, and further drives the clamping portions of the two jaw sub-parts to approach or separate from each other. The jaw driver 3322 is preferably a cylinder. When the piston rod of the cylinder extends, it drives the jaw 3321 to open, and when the piston rod of the cylinder retracts, it drives the jaw 3321 to close. After the gripper assembly 332 rises in the vertical direction, the longitudinal steel bars of the wire welded mesh fall between the two clamping portions of the gripper, and the jaw driver 3322 drives the clamping portions of the two jaw sub-parts to approach each other to clamp the steel bars. In other embodiments, the jaw 3321 may also be other structures, which are not specifically limited herein.

[0097] The wire clamping seat 333 in this embodiment includes a wire clamping seat body 3331. The wire clamping seat body 3331 is slidably connected to the vertical lifting beam 3351. Specifically, the wire clamping seat body 3331 is connected to the top border of the rectangular frame of the vertical lifting beam 3351.

The vertical end of the clamping block 3332 is connected to the upper surface of the wire clamping seat body 3331. The longitudinal steel bars of the welded steel bar mesh can be placed in the space surrounded by the vertical part and the horizontal part of the clamping block 3332. The wire clamping seat 333 is provided on the other side of the lifting roller 331, and the wire clamping seat 333 fixes the welded steel bar mesh in the horizontal direction.

[0098] Further, a guiding plate 337 is also provided between the wire clamping seat 333 and the supporting roller 331. A plurality of notches 3371 are spaced along the length direction of the guiding plate 337 on the guiding plate 337. Each notch 3371 can accommodate the longitudinal steel bars of the welded steel bar mesh, so as to guide the placement position of the welded steel bar mesh, and can also position the welded steel bar mesh, facilitating the clamping assembly of the gripper to clamp the longitudinal steel bars of the welded steel bar mesh.

[0099] The bending mechanism 34 is arranged on one side of the wire clamping seat 333, opposite to the supporting roller 331, and is used for bending the welded steel bar mesh. In this embodiment, in combination with Figure 2 , Figure 10 and Figure 11 as shown, the bending mechanism 34 includes a rotating cylinder 341.

Preferably, a connecting rod assembly 343 is connected between the rotating cylinder 341 and the wire clamping seat body 3331 of the wire clamping seat 333. The rotating cylinder 341 is connected with a bending driver 344, and the bending driver 344 drives the rotating cylinder 341 to rotate to adjust the distance between the wire pressing roller 342 and the position to be bent of the welded steel bar mesh, so as to realize the bending of the welded steel bar mesh.

[0100] Specifically, both ends of the wire pressing roller 342 are connected to the rotating cylinder 341 through wire pressing roller brackets.

[0102] In this embodiment, a position detector 345 is installed on the bending driver 344 to make the driving stroke of the bending driver 344 controllable, thereby controlling the bending angle of the steel bar welded mesh. The position detector 345 is preferably an encoder.

[0103] After the steel bar welded mesh is bent and the bending mesh unit 3 moves to the next position to be bent, in order to prevent the steel bar welded mesh from deforming due to its own weight sagging, the lifting platform unit 2 supports the bent steel bar welded mesh. In this embodiment, as Figures 12 - 15 shown, the lifting platform unit 2 includes a lifting base 21 and a lifting plate 22. The lifting plate 22 is arranged above the lifting base 21. A support roller 23 is provided on the top surface of the lifting plate 22 for supporting the steel bar welded mesh. The support roller 23 is provided to facilitate the removal of the steel bar welded mesh from the lifting platform unit 2 and reduces the friction between the steel bar welded mesh and the lifting platform unit 2.

[0104] The lifting drive assembly 24 includes an inner support beam 241 and an outer support beam 242 which are cross - arranged and hinged in the middle. The inner support beam 241 and the outer support beam 242 are connected to form a scissor shape. One end of the inner support beam 241 is slidably connected to the lifting base 21, and the other end of the inner support beam 241 is hinged to the lifting plate 22. One end of the outer support beam 242 is slidably connected to the lifting plate 22, and the other end of the outer support beam 242 is slidably connected to the lifting base 21. The sliding range of the outer support beam 242 and the inner support beam 241 determines the rising height of the lifting plate 22.

[0105] Specifically, long - strip chutes are provided on both the lifting plate 22 and the lifting base 21. Sliders are hinged to the ends of the outer support beam 242 and the inner support beam 241 respectively, and the sliders slide in the long - strip chutes.

[0106] The lifting drive assembly 24 further includes a lifting driver. The lifting driver is hinged to one of the outer support beam 242 and the inner support beam 241, and the driving end of the lifting driver is hinged to the other one.

[0107] In this embodiment, the lifting drive includes an inner support lifting drive 243 and an outer support lifting drive 244. In order to improve the supporting force for the lifting plate 22, in this embodiment, at least two groups of inner support beams 241 and outer support beams 242 that are cross - arranged and hinged in the middle are provided. The inner support beams 241 are connected by a first inner support connecting beam 246 and a second inner support connecting beam 247, and the first inner support connecting beam 246 and the second inner support connecting beam 247 are arranged near the hinge points of the inner support beam 241 and the outer support beam 242, and the first inner support connecting beam 246 and the second inner support connecting beam 247 are arranged on both sides of the hinge point. The outer support beams 242 are connected by a first outer support connecting beam 248 and a second outer support connecting beam 249. The first outer support connecting beam 248 is arranged near the hinge point of the outer support beam 242 and the lifting base 21, and the second outer support connecting beam 249 is arranged near the sliding connection of the outer support beam 242 and the lifting plate 22. The inner support lifting drive 243 is hinged and installed on the first outer support connecting beam 248, and the driving end of the inner support lifting drive 243 is hinged to the second inner support connecting beam 247. Preferably, the driving end of the inner support lifting drive 243 is connected to the second inner support connecting beam 247 through a fish - eye joint. The outer support lifting drive 244 is hinged and installed on the second outer support connecting beam 249, and the driving end of the outer support lifting drive 244 is hinged to the first inner support connecting beam 246. Preferably, the driving end of the outer support lifting drive 244 is connected to the first inner support connecting beam 246 through a fish - eye joint. The installation methods of the inner support lifting drive 243 and the outer support lifting drive 244, while realizing the lifting of the lifting plate 22, do not affect the lowering of the lifting plate 22 to fit the lifting base 21, providing enough walking space for the bending net unit 3.

[0108] Both the inner support lifting drive 243 and the outer support lifting drive 244 are preferably cylinders.

[0109] The lifting drive assembly 24 further includes an auxiliary drive 245. The auxiliary drive 245 is used to preferentially lift the lifting plate 22 by a preset height. That is, after the auxiliary drive 245 pushes the lifting plate 22 to rise by a certain height, the inner support lifting drive 243 and the outer support lifting drive 244 then push the inner support beam 241 and the outer support beam 242 to rise, so that the lifting plate 22 rises to the specified height to support the welded steel bar mesh.

[0110] In this embodiment, the auxiliary driver 245 includes an auxiliary cylinder. A jacking plate is connected to the end of the piston rod of the auxiliary cylinder. A contact plate capable of contacting the jacking plate is provided on the lifting plate 22. When the lifting plate 22 is in the lowest position, the contact plate contacts the jacking plate. When the lifting plate 22 needs to rise, the auxiliary cylinder drives the jacking plate to rise to jack up the lifting plate 22. After rising a certain height, the inner support lifting driver 243 and the outer support lifting driver 244 push the lifting plate 22 to rise.

[0111] Preferably, auxiliary drivers 245 are provided on at least opposite sides of the lifting plate 22 to make the force on the lifting plate 22 uniform.

[0112] When using the steel bar welded mesh bending device provided in this embodiment to bend a steel bar welded mesh, the steel bar welded mesh to be bent is placed at the processing position of the steel bar welded mesh bending device. The bending mesh unit 3 adjusts its position on the bottom beam 1 according to the position of the steel bar welded mesh to be processed, and then bends the steel bar welded mesh. After bending the steel bar welded mesh, when the bending mesh unit 3 needs to move to the next position to be bent, the bent steel bar welded mesh is supported by the lifting platform unit 2.
