Description

Technical Field

[0001] This invention belongs to the field of steel bar welding technology, specifically a steel bar skeleton welding device for laying prestressed steel bars. Background Technology

[0002] Reinforcing steel cages, also known as steel reinforcement cages, are mainly used in concrete structures. Their core function is to enhance the tensile strength of concrete structures and compensate for the lack of tensile strength in concrete. They mainly consist of straight bars and stirrups, which are connected together by welding.

[0003] In existing technologies, when welding straight bars and stirrups, support mechanisms are often used to provide support and positioning. Since straight bars are usually long, several sets of support mechanisms are usually arranged at intervals to provide segmented support for the straight bars, so as to avoid large bending of the straight bars due to their own weight during welding and improve the welding effect. However, after welding, the support mechanisms located in the middle position are easily restricted by the straight bars and corresponding stirrups, making it difficult to release the support for the straight bars. As a result, the welded straight bars and stirrups cannot be easily removed from the support mechanisms. Summary of the Invention

[0004] In view of the shortcomings of the prior art, the technical problem to be solved by the embodiments of the present invention is to provide a welding device for prestressed steel reinforcement cage for laying.

[0005] To solve the above-mentioned technical problems, the present invention provides the following technical solution:

[0006] A welding device for prestressed steel reinforcement cages includes a base plate, an annular support rod, a clamping assembly, and a driving assembly.

[0007] The annular support rods are provided in several groups, and these annular support rods are movably disposed on the upper part of the base plate and distributed at intervals along the length of the base plate.

[0008] Each of the aforementioned annular support rods is equipped with several clamping components, which are used to clamp several straight ribs respectively.

[0009] Each set of annular support rods is provided with a set of driving components on its inner side. The driving components are used to deform the annular support rods, thereby increasing or decreasing the area enclosed by the annular support rods.

[0010] When the area enclosed by the annular support rod decreases, the welded steel cage is vertically removed from the outside of the annular support rod.

[0011] As a further improvement of the present invention: the annular support rod includes a side support rod and a vertical support rod.

[0012] The vertical support rods are provided in two sets, which are distributed opposite to each other. The side support rods are provided in four sets, which together with the two sets of vertical support rods form a hexagonal structure. Several clamping components are installed on the side walls of the four sets of side support rods and the two sets of vertical support rods.

[0013] As a further improvement of the present invention: a base is fixedly provided on the upper part of the base plate.

[0014] The drive assembly includes a drive rod, a top seat, a threaded sleeve, and a connecting rod.

[0015] The lower end of the drive rod is rotatably connected to the base, and the upper end passes through the top seat and rotatably engages with the top seat. The top seat is located directly above the base. The drive rod is positioned between the two sets of vertical support rods. The drive rod has two sets of threaded segments with opposite directions of rotation on its exterior. Two sets of threaded sleeves are provided, and the two sets of threaded sleeves are fitted onto the exterior of the drive rod and threadedly engage with the two sets of threaded segments respectively.

[0016] Two sets of side support rods are hinged at one end to the base, and their other ends are movably connected to the inner wall of one set of vertical support rods, respectively. The other two sets of side support rods are hinged at one end to the top seat, and their other ends are movably connected to the inner wall of one set of vertical support rods, respectively.

[0017] The connecting rod is provided in four sets. One end of each of the four sets of connecting rods is hinged to the inner wall of the four sets of side support rods. The other end of two sets of connecting rods is hinged to one set of threaded sleeves, and the other end of the other two sets of connecting rods is hinged to the other two sets of threaded sleeves.

[0018] As a further improvement of the present invention: a slide rail is fixedly provided on the inner wall of both sets of vertical support rods, and a slider is slidably provided on the slide rail, and one end of the side support rod is hinged to the slider.

[0019] As a further improvement to the present invention: the clamping assembly includes a clamping plate, a screw, and a knob.

[0020] The screw passes through the rod body of the annular support member and is threaded into the rod body. The clamp is located at the end of the screw located outside the annular support member, and the knob is located at the end of the screw located inside the annular support member. The clamp is perpendicular to the screw.

[0021] As a further improvement of the present invention: the clamping plate is rotatably engaged with the screw.

[0022] As a further improvement of the present invention: the two sets of vertical support rods are also connected to the drive rod by a guide assembly, which is used to guide the two sets of vertical support rods to move closer to each other and further apart.

[0023] As a further improvement of the present invention: the guiding assembly includes a guide rod, a guide sleeve, and a support sleeve.

[0024] The support sleeve is rotatably sleeved on the outside of the drive rod, and the guide sleeve is fixedly installed on the outer wall of the support sleeve. One end of the guide rod is fixedly connected to the inner wall of the vertical support rod, and the other end extends into the inside of the guide sleeve and is telescopically engaged with the guide sleeve.

[0025] Compared with the prior art, the beneficial effects of the present invention are:

[0026] In this embodiment of the invention, when welding is required on the reinforcing cage, several stirrups can be placed on the sides of several annular support members, and then several straight bars can be passed through the inside of the stirrups. At this time, the straight bars act on the outside of the annular support members, forming a cage-like structure between the straight bars and the stirrups. Then, several clamping components on the annular support members are used to clamp the straight bars. Subsequently, the distance between the stirrups is adjusted, and the stirrups are welded to the straight bars. After welding is completed, the clamping components release the clamping state on the straight bars, and then several driving components drive the... The deformation of several annular support members reduces the area enclosed by them. When the area enclosed by the several annular support members shrinks, the steel cage can be manually lifted or hoisted by a hoisting machine. At this time, the several annular support members can be removed from the gap between two adjacent sets of straight bars, allowing the steel cage to be smoothly removed from the outside of the annular support members. Compared with the existing technology, during the welding of the steel cage, the several annular support members can provide stable support for several straight bars, thereby improving the welding effect. After welding, the drive component can be used to deform and shrink the annular support members, so as to facilitate the smooth removal of the steel cage. Attached Figure Description

Detailed Implementation

[0032] The technical solution of the present invention will be further described in detail below with reference to specific embodiments.

[0033] Embodiments of the present invention are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0034] Please see Figure 1 as well as Figure 2 This embodiment provides a welding device for a prestressed steel reinforcement cage, including a base plate 10, annular support rods 20, clamping components 40, and a driving component 50. Several groups of annular support rods 20 are provided, movably disposed on the upper part of the base plate 10 and spaced apart along the length of the base plate 10. Several clamping components 40 are provided on the rod body of each group of annular support rods 20, and these clamping components 40 are used to clamp several straight steel bars respectively. A driving component 50 is provided inside each group of annular support rods 20, and the driving component 50 is used to deform the annular support rods 20, causing the area enclosed by the annular support rods 20 to increase or decrease. When the area enclosed by the annular support rods 20 decreases, the welded steel cage is vertically removed from the outside of the annular support rods 20.

[0035] When welding is required on the reinforcing cage, several stirrups can be placed on the sides of several annular support members 20, and several straight bars can be passed through the inside of the stirrups. At this time, the straight bars act on the outside of the annular support members 20, forming a cage-like structure between the straight bars and the stirrups. Then, several clamping components 40 on the annular support members 20 are used to clamp the straight bars. The distance between the stirrups is then adjusted and the stirrups are welded to the straight bars. After welding, the clamping components 40 are released from clamping the straight bars, and then several driving components 50 are used to deform the annular support members 20, reducing the area enclosed by the annular support members 20. When the area enclosed by the annular support members 20 is reduced, the reinforcing cage can be manually lifted or lifted with the help of hoisting machinery. At this time, the annular support members 20 can be removed from the gap between two adjacent sets of straight bars, so that the reinforcing cage can be smoothly removed from the outside of the annular support members 20.

[0036] Please see Figure 1 In one embodiment, the annular support rod 20 includes side support rods 201 and vertical support rods 202. There are two sets of vertical support rods 202, which are distributed opposite to each other. There are four sets of side support rods 201, which together with the two sets of vertical support rods 202 form a hexagonal structure. A plurality of clamping components 40 are installed on the side walls of the four sets of side support rods 201 and the two sets of vertical support rods 202.

[0037] After the steel cage is welded, several clamping components 40 release their clamping state on several straight bars. Then, the driving component 50 drives the area of ​​the hexagonal structure formed by four sets of side support rods 201 and two sets of vertical support rods 202 to shrink, so that the steel cage can be smoothly removed from the outside of the annular support rod 20.

[0038] Please see Figure 1 as well as Figure 3In one embodiment, a base 101 is fixedly disposed on the upper part of the base plate 10. The driving assembly 50 includes a driving rod 501, a top seat 502, a threaded sleeve 505, and a connecting rod 506. The lower end of the driving rod 501 is rotatably connected to the base 101, and the upper end passes through the top seat 502 and rotatably engages with the top seat 502. The top seat 502 is disposed directly above the base 101. The driving rod 501 is located between two sets of vertical support rods 202. Two sets of threaded segments 504 with opposite directions of rotation are disposed on the outside of the driving rod 501. Two sets of threaded sleeves 505 are provided, and the two sets of threaded sleeves 505 are sleeved on the outside of the driving rod 501. Each of the two sets of threaded sections 504 is threaded together. One end of each of the two sets of side support rods 201 is hinged to the base 101, and the other end is movably connected to the inner wall of one set of vertical support rods 202. One end of the other two sets of side support rods 201 is hinged to the top seat 502, and the other end is movably connected to the inner wall of one set of vertical support rods 202. The connecting rod 506 is provided in four sets. One end of each of the four sets of connecting rods 506 is hinged to the inner wall of the four sets of side support rods 201. The other end of each of the two sets of connecting rods 506 is hinged to one set of threaded sleeves 505, and the other end of the other two sets of connecting rods 506 is hinged to the other two sets of threaded sleeves 505.

[0039] After the rebar cage is welded, several clamping components 40 release their clamping grip on several straight bars. Then, the operator rotates the drive rod 501. As the drive rod 501 rotates, the threaded engagement of two sets of threaded sections 504 and two sets of threaded sleeves 505 causes the two sets of threaded sleeves 505 to move outside the drive rod 501. This movement of the threaded sleeves 505 causes four sets of connecting rods 506 to rotate. The four sets of connecting rods 506 pull four sets of diagonal braces 201 to rotate. As the diagonal braces 201 rotate, they pull two sets of vertical braces 202 closer together, thus reducing the area of ​​the hexagonal structure formed by the four sets of side braces 201 and the two sets of vertical braces 202. After the area of ​​the hexagonal structure formed by the four sets of side braces 201 and the two sets of vertical braces 202 decreases, the upward-moving rebar... The cage, with four sets of side support rods 201 and two sets of vertical support rods 202, is removed from between two adjacent sets of straight bars, allowing the steel cage to be smoothly removed from the outside of the annular support rod 20. After the steel cage is removed, the worker can rotate the drive rod 501 in the opposite direction. Through the reverse thread engagement of the two sets of threaded sections 504 and the two sets of threaded sleeves 505, the two sets of threaded sleeves 505 are driven to move in the opposite direction along the outside of the drive rod 501. The four sets of connecting rods 506 rotate in the opposite direction, thereby pushing the four sets of side support rods 201 to rotate in the opposite direction. When the four sets of side support rods 201 rotate in the opposite direction, they push the two sets of vertical support rods 202, causing the two sets of vertical support rods 202 to move away from each other. At this time, the area of ​​the annular structure formed by the four sets of side support rods 201 and the two sets of vertical support rods 202 increases to meet the subsequent welding requirements of the steel cage.

[0040] Please see Figure 4 In one embodiment, slide rails 204 are fixedly provided on the inner walls of both sets of vertical support rods 202, and sliders 203 are slidably provided on the slide rails 204. One end of the side support rod 201 is hinged to the slider 203.

[0041] When the drive rod 501 rotates, it drives the four sets of side support rods 201 to rotate. One end of the four sets of side support rods 201 pulls the two sets of vertical support rods 201 closer to each other. At the same time, the side support rods 201 drive the slider 203 to slide adaptively along the slide rail 204.

[0042] Please see Figure 1 In one embodiment, a handwheel 503 is fixedly provided on the upper end of the drive rod 501, so that the drive rod 501 can be rotated.

[0043] Please see Figure 3 as well as Figure 4 In one embodiment, the clamping assembly 40 includes a clamping plate 401, a screw 402, and a knob 403. The screw 402 passes through the rod body of the annular support rod 20 and is threadedly engaged with the rod body. The clamping plate 401 is disposed at the end of the screw 402 located outside the annular support rod 20, and the knob 403 is disposed at the end of the screw 402 located inside the annular support rod 20. The clamping plate 401 and the screw 402 are perpendicular to each other.

[0044] After several straight ribs pass through the inside of several stirrups, the straight ribs act between several clamping plates 401 and the rod body of the annular support member 20. Then, the worker turns the knob 403, which drives the screw 402 to rotate. When the screw 402 rotates, it engages with the threaded part of the annular support member 20, which in turn drives the clamping plates 401 closer to the annular support member 20, thereby clamping the straight ribs on the outer wall of the annular support member 20. After the stirrups and straight ribs are welded together, the worker turns the knob 403 in the opposite direction, which drives the screw 402 to rotate in the opposite direction. The screw 402 drives the clamping plates 401 away from the rod body of the annular support member 20, thereby releasing the clamping state of the straight ribs.

[0045] It should be understood that the screw 402 corresponding to the clamping assembly 40 on the side support rod 201 passes through the side support rod 201 and is threadedly engaged with the side support rod 201, and the screw 402 corresponding to the clamping assembly 40 on the vertical support rod 202 passes through the vertical support rod 202 and is threadedly engaged with the vertical support rod 202.

[0046] In one embodiment, the clamping plate 401 is rotatably engaged with the screw 402. When the screw 402 drives the clamping plate 401 away from the annular support rod 20 and releases the clamping state of the straight rib, the worker can rotate the clamping plate 401 relative to the screw 402 to remove the clamping plate 401 from the side of the straight rib. This avoids the clamping plate 401 hooking onto the straight rib and thus hindering the rotation of the side support rods 201 when the drive rod 501 is rotated to reduce the area enclosed by the four sets of side support rods 201 and the two sets of vertical support rods 202.

[0047] Please see Figure 1 In one embodiment, the two sets of vertical support rods 202 are also connected to the drive rod 501 by a guide assembly 30. The guide assembly 30 is used to guide the two sets of vertical support rods 202 to move closer to each other and further away from each other, so as to improve the stability of the two sets of vertical support rods 202 when moving.

[0048] Please see Figure 1 as well as Figure 4 In one embodiment, the guide assembly 30 includes a guide rod 301, a guide sleeve 302, and a support sleeve 303. The support sleeve 303 is rotatably sleeved on the outside of the drive rod 501. The guide sleeve 302 is fixedly disposed on the outer wall of the support sleeve 303. One end of the guide rod 301 is fixedly connected to the inner wall of the vertical support rod 202, and the other end extends into the inside of the guide sleeve 302 and telescopically cooperates with the guide sleeve 302.

[0049] When the drive rod 501 rotates and drives the four sets of side support rods 201 to rotate, the four sets of side support rods 201 push and pull the two sets of vertical support rods 202. At this time, the guide rod 301 adapts to the extension and retraction of the guide sleeve 302 to guide the movement of the two sets of vertical support rods 202.

[0050] In this embodiment of the invention, when welding is required on the reinforcing cage, several stirrups can be placed on the sides of several annular support members 20, and then several straight bars can be passed through the inside of the stirrups. At this time, the straight bars act on the outside of the annular support members 20, forming a cage-like structure between the straight bars and the stirrups. Then, several clamping components 40 on the annular support members 20 are used to clamp the straight bars. Subsequently, the distance between the stirrups is adjusted and the stirrups are welded to the straight bars. After welding is completed, the clamping components 40 release the clamping state of the straight bars, and then several driving components 50 drive the several straight bars to move. The deformation of the annular support rods 20 reduces the area enclosed by the several annular support rods 20. When the area enclosed by the several annular support rods 20 shrinks, the steel cage can be manually lifted or lifted by hoisting machinery. At this time, the several annular support rods 20 can be removed from the gap between two adjacent sets of straight bars, so that the steel cage can be smoothly removed from the outside of the annular support rods 20. Compared with the prior art, during the welding of the steel cage, the several annular support rods 20 can provide stable support for several straight bars, thereby improving the welding effect. After welding, the drive component 50 is used to drive the annular support rods 20 to deform and shrink, so as to facilitate the smooth removal of the steel cage.

[0051] The preferred embodiments of the present invention have been described in detail above. However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present invention.
