Description

Technical Field

[0001] This invention relates to the field of steel mesh welding technology, specifically to a welding support device and method for steel mesh used in silo foundations. Background Technology

[0002] As a large-scale bulk material storage facility, the stability of the foundation structure of a silo is directly related to the safe operation of the entire silo system. The silo foundation, as a key transitional structure connecting the silo wall and the foundation, plays an important role in uniformly transferring the upper load to the foundation. During the construction of the foundation, it is usually necessary to lay steel mesh inside the foundation to enhance its load-bearing capacity and crack resistance.

[0003] The steel mesh is composed of multiple transverse steel bars and multiple longitudinal steel bars arranged in an alternating pattern. The transverse steel bars and longitudinal steel bars are fixedly connected by binding or welding to form a stable grid-like skeleton structure. In actual engineering, the spacing between transverse steel bars and the spacing between longitudinal steel bars on the steel mesh are not fixed, but will be adjusted and changed according to the specific engineering requirements, depending on the specifications of the silo, the load conditions and the requirements of the design specifications.

[0004] To ensure that the steel mesh remains in its designed position without deformation or sinking during concrete pouring, it is usually necessary to install a support device below or inside the steel mesh. For steel mesh fixed by welding, the welded support device must not only play a supporting and positioning role, but also be compatible with the welding process of the steel mesh.

[0005] The existing welded support device for steel mesh cannot absorb energy from the longitudinal steel bars during use. This causes the longitudinal steel bars to vibrate significantly after falling from the feeding equipment. Because the welding process is fast, the longitudinal steel bars are welded to the transverse steel bars before the vibration stops. This results in the longitudinal steel bars having internal stress after welding, making the weld not strong enough.

[0006] In addition, the existing welded support device for steel mesh cannot adjust the spacing between steel bars as needed, making it inconvenient to use a single set of equipment to produce steel mesh with different spacings.

[0007] Therefore, a welded support device for the steel mesh of silo foundation is needed to solve the above problems. Summary of the Invention

[0008] The purpose of this invention is to provide a welding support device and method for steel mesh reinforcement in silo foundations, in order to solve the problems mentioned in the background art, such as that existing welding support devices for steel mesh reinforcement are not convenient for absorbing energy from longitudinal steel bars and are not convenient for producing steel mesh reinforcement with different spacings using a single set of equipment.

[0009] To achieve the above objectives, the present invention provides the following technical solution:

[0010] A welding support device for steel mesh reinforcement in a silo foundation includes a support base and guide rollers mounted thereon. A limiting shaft parallel to the guide rollers is also mounted on the support base, and an adjustable transverse material guiding mechanism is mounted on the limiting shaft. The adjustable transverse material guiding mechanism includes a transverse guide roller for guiding transverse steel bars. A longitudinal material guiding energy-absorbing mechanism is provided on both inner sides of the support base, and the longitudinal material guiding energy-absorbing mechanism includes a discharge guide groove on both inner sides of the support base. A central guide groove is connected through the upper opening of the discharge guide groove. A swing-down welding mechanism is installed between the two inner sides of the support base, and the swing-down welding mechanism includes a welding head for welding transverse and longitudinal steel bars.

[0011] Preferably, the swing welding pressing mechanism further includes a support frame plate connecting the two inner sides of the support base, and the front shaft end of the support frame plate is connected to a bearing on one side of the support base, the rear shaft end of the support frame plate is connected through to a bearing on the other side of the support base, and a servo motor fixedly connected to the rear shaft end of the support frame plate is installed on the outside of the other side of the support base.

[0012] Preferably, the support frame plate is provided with a strip-shaped through hole, and a mounting bracket slides through the strip-shaped through hole. The upper end of the mounting bracket is rotatably connected to the side of the support frame plate by a roller, and an electric telescopic rod is installed at the lower end of the mounting bracket. The welding head is installed at the telescopic end of the electric telescopic rod.

[0013] Preferably, the adjustable transverse guiding mechanism further includes sliding grooves on both sides of the support base, and a drive plate is provided on the upper part of the support base. Both ends of the drive plate are slidably connected to the corresponding sliding grooves through protrusions. A cylinder is installed on the support base, and the telescopic end of the cylinder is shaft-connected to one end of the support arm. The other end of the support arm is shaft-connected to the corresponding drive plate.

[0014] Preferably, the support base has mounting seats evenly distributed inside, and transverse guide rollers are provided on the upper surfaces of both ends of the mounting seats. A corresponding longitudinal support block is fixedly connected to the middle of each mounting seat. The longitudinal support block is used to support the longitudinal reinforcing bars. Limiting protrusions are also provided at both ends of the upper surface of the mounting seat, and the limiting shaft moves through the corresponding limiting protrusion. The drive plate is provided with guide grooves that pass through its upper and lower sides. A guide block is provided on the lower surface of the mounting seat, and the guide block slides through the corresponding guide groove.

[0015] Preferably, the guide grooves are fan-shaped to ensure that the distance between the mounting bases changes synchronously when the drive plate moves.

[0016] Preferably, one end of each of the longitudinal support blocks is fixedly connected to a synchronizing arm, and the upper end of the synchronizing arm is provided with an arc-shaped groove, in which a corresponding sliding block is slidably connected, and the sliding block is provided on the side of the lower end of each mounting bracket.

[0017] Preferably, the longitudinal material guiding energy absorption mechanism further includes a through column that can move through the support base to the material guide groove, and the end bearing of the through column in the material guide groove is connected to a material guide shaft. The material guide shaft has an I-shaped structure, and the through column bearing is connected to its middle part.

[0018] Preferably, a piston rod coaxial with the end of the through column outside the support is fixedly connected, and an oil pipe is fixedly connected to the support at a position corresponding to the piston rod. The rod end of the piston rod is sealed and slidably extended into the interior of the oil pipe, and the piston end of the piston rod is seamlessly slidably connected to the inner wall of the oil pipe. Oil passage holes are evenly distributed on both sides of the piston end of the piston rod, and a spring is provided between the piston end of the piston rod and the inner end of the oil pipe. The oil pipe is filled with damping oil.

[0019] A method for supporting a welded support device for a steel mesh reinforcement plate on a silo foundation, the method comprising:

[0020] Step 1: As needed, operate the cylinder to move one end of the support arm downwards or upwards, thereby driving the two drive plates closer or further apart. When the two drive plates are close together or far apart, the distance between the mounting seats can be adjusted by the limit shaft and the limit protrusion, thereby adjusting the distance between the transverse guide rollers. In addition, the distance between the electric telescopic rods can be adjusted by the synchronous arm, the arc groove and the sliding block, as well as the mounting frame and the rollers, thereby achieving the purpose of synchronous adjustment of the distance between the welding heads, the transverse guide rollers and the longitudinal support blocks.

[0021] Step 2: The transverse steel bar feeding device feeds the transverse steel bar from the right side of the support base into the support base. During the process, the support is provided by the guide roller, and the transverse guide roller guides the transverse steel bar.

[0022] Step 3: The longitudinal steel bar feeding equipment feeds the longitudinal steel bar into the central guide groove. During the process, the longitudinal steel bar is centered by the guidance of the central guide groove. When the longitudinal steel bar falls along the discharge guide groove, it contacts multiple sets of discharge shafts. Through the structure composed of piston rod, oil passage hole, oil pipe, spring and damping oil, the energy is absorbed, reducing the vibration energy generated when the longitudinal steel bar falls, so that when the longitudinal steel bar lands on the longitudinal support block, it no longer has a large kinetic energy.

[0023] Step 4: Start the servo motor and rotate the support frame plate to rotate the electric telescopic rod and welding head to a vertical position. During the process, the arc groove and sliding block can provide stable support for the rotation of the electric telescopic rod.

[0024] Step 5: Start the electric telescopic rod. The electric telescopic rod drives the welding head to move down, so as to weld the intersection of the transverse and longitudinal reinforcing bars.

[0025] Compared with the prior art, the beneficial effects of the present invention are: the welding support device for the steel mesh of the silo foundation can adjust the spacing between the transverse steel bars as needed, and can absorb the energy of the falling longitudinal steel bars, greatly reducing their internal stress during welding, which helps to ensure their stability during welding, thereby improving the weld strength.

[0026] 1. By driving one end of the support arm with a cylinder, the two drive plates can be moved closer or further apart. The distance between adjacent mounting seats can be adjusted by the guide block and guide groove, which means that the distance between the transverse guide rollers can be adjusted, thereby adjusting the spacing between the transverse reinforcing bars. In addition, the electric telescopic rods can be driven to move synchronously by the longitudinal support block, the synchronous arm and the sliding block, thereby adjusting the spacing between the electric telescopic rods, which means adjusting the spacing between the welding heads. By synchronously adjusting the spacing between the welding heads and the spacing between the transverse reinforcing bars, the same set of equipment can weld steel mesh with different requirements, which helps to reduce production costs and improve the practicality of the equipment.

[0027] 2. The centering guide groove allows the longitudinal steel bars to automatically center themselves during the descent. In addition, during the feeding process, when the longitudinal steel bars pass through several sets of feeding shafts, the energy-absorbing structure composed of piston rod, oil passage hole, oil pipe and spring can reduce the vibration energy generated when the longitudinal steel bars fall to a minimum, ensuring that there will be no large vibration during welding. This can prevent the generation of large internal stress, help improve the stability during welding, and ensure the firmness of the weld. Attached Figure Description

[0039] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0040] Please see Figures 1-10 The present invention provides the following technical solution:

[0041] Example 1: To solve the problem that the spacing between transverse reinforcing bars cannot be adjusted as needed by the welding support device for reinforcing mesh in the past, the following technical solution is provided: a welding support device for reinforcing mesh of silo foundation, including a support base 1 and a guide roller 2 installed thereon. The support base 1 is also equipped with a limiting shaft 19 parallel to the guide roller 2, and an adjustable transverse material guiding mechanism is installed on the limiting shaft 19. The adjustable transverse material guiding mechanism includes a transverse guide roller 5 for guiding the transverse reinforcing bars. A swinging downward pressing welding mechanism is installed between the two inner sides of the support base 1, and the swinging downward pressing welding mechanism includes a welding head 4 for welding the transverse reinforcing bars and the longitudinal reinforcing bars.

[0042] In a preferred embodiment of the invention, the swing welding pressing mechanism further includes a support frame plate 12 connecting the two inner sides of the support base 1, and the front shaft end of the support frame plate 12 is connected to a bearing on one side of the support base 1, the rear shaft end of the support frame plate 12 is connected through to a bearing on the other side of the support base 1, and a servo motor 6 is installed on the outside of the other side of the support base 1 and fixedly connected to the rear shaft end of the support frame plate 12.

[0043] In the above technical solution, the rotation of the support frame plate 12 is controlled by the servo motor 6, which can control the rotation of multiple welding heads 4 on the support frame plate 12, thereby preventing the welding heads 4 and the electric telescopic rod 3 from obstructing the fall of the longitudinal steel bars.

[0044] In a preferred embodiment of the invention, a strip-shaped through hole is provided on the support frame plate 12, and a mounting bracket 13 slides through the strip-shaped through hole. The upper end of the mounting bracket 13 is rotatably connected to the side of the support frame plate 12 by a roller 14, and an electric telescopic rod 3 is installed at the lower end of the mounting bracket 13. A welding head 4 is installed at the telescopic end of the electric telescopic rod 3.

[0045] In the above technical solution, the strip-shaped through hole facilitates the stable movement of the electric telescopic rod 3 under the action of the mounting frame 13 and the roller 14, and helps the welding head 4 and the electric telescopic rod 3 to be adjusted synchronously with the adjustment of the distance between the transverse guide rollers 5.

[0046] In a preferred embodiment of the invention, the adjustable transverse guiding mechanism further includes sliding grooves 7 provided on both sides of the support base 1, and a drive plate 8 provided on the upper part of the support base 1. Both ends of the drive plate 8 are slidably connected to the corresponding sliding grooves 7 through protrusions. A cylinder 21 is installed on the support base 1, and the telescopic end of the cylinder 21 is shaft-connected to one end of the support arm 22, and the other end of the support arm 22 is shaft-connected to the corresponding drive plate 8.

[0047] In the above technical solution, the cylinder 21 controls the support arm 22, which can drive the two drive plates 8 to move away from each other or move closer to each other.

[0048] In a preferred embodiment of the invention, mounting seats 9 are evenly distributed inside the support base 1, and transverse guide rollers 5 are provided on the upper surfaces of both ends of the mounting seats 9. A corresponding longitudinal support block 18 is fixedly connected to the middle of each mounting seat 9. The longitudinal support block 18 is used to support the longitudinal reinforcing bars. Limiting protrusions 10 are also provided at both ends of the upper surface of the mounting seat 9, and the limiting shaft 19 moves through the corresponding limiting protrusion 10. The drive plate 8 is provided with guide grooves 11 that pass through its upper and lower sides. A guide block 20 is provided on the lower surface of the mounting seat 9, and the guide block 20 slides through the corresponding guide groove 11.

[0049] In the above technical solution, the distance between adjacent mounting seats 9 can be adjusted when the drive plate 8 moves by means of the guide block 20 and the guide groove 11.

[0050] In a preferred embodiment of the invention, the guide grooves 11 are fan-shaped to allow the distance between the mounting bases 9 to change synchronously as the drive plate 8 moves.

[0051] In the above technical solution, the spacing between several mounting bases 9 can be adjusted synchronously.

[0052] In a preferred embodiment of the invention, a synchronizing arm 15 is fixedly connected to one end of each longitudinal support block 18, and an arc-shaped groove 16 is provided at the upper end of the synchronizing arm 15. A corresponding sliding block 17 is slidably connected in the arc-shaped groove 16, and the sliding block 17 is provided on the side of the lower end of each mounting bracket 13.

[0053] In the above technical solution, the spacing between the welding heads 4 can be adjusted synchronously through the synchronous arm 15, the arc groove 16 and the sliding block 17.

[0054] according to Figures 1-7 When in use, the transverse steel bars are fed from the right end of the support base 1 through the transverse steel bar feeding device, and the transverse steel bars are guided by the corresponding transverse guide roller 5.

[0055] In addition, the longitudinal steel bars are fed into the longitudinal support block 18 by the longitudinal steel bar feeding equipment, and then the servo motor 6 is started to make the support frame plate 12 and its mounting bracket 13, electric telescopic rod 3 and welding head 4 rotate synchronously.

[0056] After the electric telescopic rod 3 and the welding head 4 are rotated to the vertical position, the electric telescopic rod 3 is activated to move the welding head 4 downward, thereby welding the intersection of the transverse and longitudinal reinforcing bars.

[0057] When it is necessary to adjust the spacing between the transverse steel bars, start the cylinder 21 to move one end of the support arm 22 connected to it upward or downward.

[0058] When one end of the support arm 22 moves upward, the two drive plates 8 will move away from each other; when one end of the support arm 22 moves downward, the two drive plates 8 will move closer to each other.

[0059] When the drive plate 8 moves, the distance between the mounting base 9 can be adjusted through the guide groove 11 and the guide block 20;

[0060] Because the transverse guide roller 5 is installed on the mounting base 9, the distance between the transverse guide rollers 5 can be adjusted synchronously, that is, the distance between the transverse steel bars can be adjusted.

[0061] In addition, since the structure formed by the longitudinal support block 18 and the synchronous arm 15 is fixedly connected to the mounting base 9, and the electric telescopic rod 3 slides in the arc groove 16 on the synchronous arm 15 through the sliding block 17, the distance between the electric telescopic rods 3 can be adjusted synchronously.

[0062] When the electric telescopic pole 3 moves, the rollers 14 enhance its stability.

[0063] Example 2: To solve the problem in Example 1 where it is inconvenient to absorb energy from the longitudinal steel bars, resulting in internal stress in the longitudinal steel bars during welding and insufficient strength after welding, the following technical solution is provided: Specifically, a longitudinal material guiding energy absorbing mechanism is provided on both inner sides of the support base 1, and the longitudinal material guiding energy absorbing mechanism includes a material guide groove 24 provided on both inner sides of the support base 1, and a central guide groove 23 is connected through the upper opening of the material guide groove 24.

[0064] In a preferred embodiment of the invention, the longitudinal material guiding energy absorption mechanism further includes a through column 25 that movably passes through the support base 1 to the discharge guide groove 24, and the end bearing of the through column 25 located in the discharge guide groove 24 is connected to a discharge shaft 26, which has an I-shaped structure, and the through column 25 is connected to the middle of the shaft.

[0065] In the above technical solution, the kinetic energy of the longitudinal steel bar can be converted into the rotational kinetic energy of the cutting shaft 26, which helps to reduce the kinetic energy of the longitudinal steel bar.

[0066] In a preferred embodiment of the invention, a piston rod 27 coaxially connected to the end of the through column 25 outside the support base 1, and an oil pipe 29 fixedly connected to the support base 1 at a position corresponding to the piston rod 27. The rod end of the piston rod 27 is sealed and slidably extended into the interior of the oil pipe 29, and the piston end of the piston rod 27 is seamlessly slidably connected to the inner wall of the oil pipe 29. Oil passage holes 28 are evenly distributed on both sides of the piston end of the piston rod 27, and a spring 30 is provided between the piston end of the piston rod 27 and the inner end of the oil pipe 29. The oil pipe 29 is filled with damping oil.

[0067] In the above technical solution, the buffer mechanism composed of spring 30 and damping oil can further absorb the kinetic energy of the longitudinal steel bar, ensuring that it will not generate large vibrations after being supported by the longitudinal support block 18, thus ensuring the stability of the welding and avoiding the problem of insufficient strength after welding.

[0068] according to Figures 8-10 When in use, the longitudinal steel bar feeding device feeds the longitudinal steel bar into the inlet of the centering guide groove 23. The longitudinal steel bar is automatically centered by the guidance of the centering guide groove 23, and then moves down under its own gravity.

[0069] When the longitudinal steel bars move downward, they come into contact with the feeding shaft 26, causing the feeding shaft 26 to rotate. During the rotation, the feeding shafts 26 will also move away from each other.

[0070] When the feeding shaft 26 rotates, it can convert the kinetic energy of the longitudinal steel bars into the kinetic energy of the rotation of the feeding shaft 26, and thus absorb part of the kinetic energy of the longitudinal steel bars.

[0071] When the feeding shaft 26 moves, it will compress the spring 30. The buffer structure formed by the spring 30 and the damping oil can further absorb the kinetic energy of the longitudinal steel bar, so that the longitudinal steel bar will not have a large kinetic energy after contacting the longitudinal support block 18, thus preventing it from generating a large vibration.

[0072] Because the longitudinal steel bars are fully energized before welding, it can be ensured that the longitudinal steel bars will not vibrate during welding, thus preventing welding instability. In addition, it can also ensure the strength of the weld after welding.

[0073] A method for supporting a welded support device for a steel mesh reinforcement plate on a silo foundation, the method comprising:

[0074] Step 1: As needed, operate cylinder 21 to move one end of support arm 22 down or up, thereby driving the two drive plates 8 to move closer or further apart. When the two drive plates 8 move closer or further apart, the distance between the mounting bases 9 can be adjusted by the limit shaft 19 and the limit protrusion 10, thereby adjusting the distance between the transverse guide rollers 5. In addition, the distance between the electric telescopic rods 3 can be adjusted by the synchronous arm 15, the arc groove 16 and the sliding block 17, as well as the mounting frame 13 and the roller 14, thereby achieving the purpose of synchronous adjustment of the distance between the welding heads 4, between the transverse guide rollers 5 and between the longitudinal support blocks 18.

[0075] Step 2: The transverse steel bar feeding device feeds the transverse steel bar from the right side of the support base 1 into the support base 1. During the process, the guide roller 2 provides support and the transverse guide roller 5 guides the transverse steel bar.

[0076] Step 3: The longitudinal steel bar feeding device feeds the longitudinal steel bar into the centering guide groove 23. During the process, the longitudinal steel bar is centered by the guidance of the centering guide groove 23. When the longitudinal steel bar falls along the discharge guide groove 24, it contacts multiple sets of discharge shafts 26. Energy is absorbed through the structure composed of piston rod 27, oil hole 28, oil pipe 29, spring 30 and damping oil, reducing the vibration energy generated when the longitudinal steel bar falls, so that when the longitudinal steel bar lands on the longitudinal support block 18, it no longer has a large kinetic energy.

[0077] Step 4: Start the servo motor 6 and rotate the support frame plate 12 to rotate the electric telescopic rod 3 and the welding head 4 to a vertical position. During the process, the arc groove 16 and the sliding block 17 can provide stable support for the rotation of the electric telescopic rod 3.

[0078] Step 5: Start the electric telescopic rod 3. The electric telescopic rod 3 drives the welding head 4 to move down, so as to weld the intersection of the transverse and longitudinal steel bars.

[0079] The contents not described in detail in this specification are existing technologies known to those skilled in the art.

[0080] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.

A method for supporting a welded support device for reinforcing mesh in a silo foundation, applicable to the welded support device for reinforcing mesh in a silo foundation as described in any one of claims 1-9, characterized in that: The method includes: Step 1: As needed, operate the cylinder (21) to move one end of the support arm (22) down or up, thereby driving the two drive plates (8) to move closer or further apart. When the two drive plates (8) move closer or further apart, the distance between the mounting bases (9) can be adjusted by the limit shaft (19) and the limit protrusion (10), thereby adjusting the distance between the transverse guide rollers (5). In addition, the distance between the electric telescopic rods (3) can be adjusted by the synchronous arm (15), the arc groove (16) and the sliding block (17), as well as the mounting frame (13) and the roller (14), thereby achieving the purpose of synchronous adjustment of the distance between the welding heads (4), the transverse guide rollers (5) and the longitudinal support blocks (18). Step 2: The transverse steel bar feeding device feeds the transverse steel bar from the right side of the support base (1) into the support base (1). During the process, the support is provided by the guide roller (2), and the transverse steel bar is guided by the transverse guide roller (5). Step 3: The longitudinal steel bar feeding device feeds the longitudinal steel bar into the centering guide groove (23). During the process, the longitudinal steel bar is centered by the guidance of the centering guide groove (23). When the longitudinal steel bar falls along the discharge guide groove (24), it contacts multiple sets of discharge shafts (26). Through the structure composed of piston rod (27), oil hole (28), oil pipe (29), spring (30) and damping oil, it absorbs energy and reduces the vibration energy generated when the longitudinal steel bar falls, so that when the longitudinal steel bar falls on the longitudinal support block (18), it no longer has a large kinetic energy. Step 4: Start the servo motor (6) and rotate the support frame plate (12) to rotate the electric telescopic rod (3) and welding head (4) to the vertical position. During the process, the arc groove (16) and sliding block (17) can provide stable support for the rotation of the electric telescopic rod (3). Step 5: Start the electric telescopic rod (3). The electric telescopic rod (3) drives the welding head (4) to move down, so as to realize the welding of the intersection of the transverse and longitudinal steel bars.
