Description

Technical Field

[0001] The invention relates to the technical field of welding equipment, and in particular to an anchor rod steel bar welding device. Background Art

[0002] The anchor welding centering bracket is a device used for anchor support. Its main function is to ensure that the anchor is located in the center of the drill hole and that the rod body has a sufficient protective layer thickness. This bracket is usually composed of an anchor body, a centering bracket and an anchor head. The centering bracket is small in size and has a special welding angle. On-site welding and installation are often unqualified because the welding angle does not meet the design requirements, resulting in rework, affecting the project progress, increasing project costs, and sometimes even affecting the project quality due to inadequate management.

[0003] A Chinese patent document with announcement number CN217316688U discloses an anchor rod manufacturing workbench, including a support platform, a threading machine support platform, a guide pulley, an anchor rod clamping device, and a steel bar bending bracket. A support leg is fixedly provided at the bottom end of the support platform, the threading machine support platform is slidably arranged at the bottom end of the support platform, the bottom end of the threading machine support platform is hinged with folding legs, the top end of the threading machine support platform is detachably connected to the threading machine, at least one guide pulley and at least one anchor rod clamping device are fixed to the top end of the support platform along the length direction of the support platform, and at least one group of steel bar bending brackets are fixed to the side of the top end of the support platform away from the threading machine.

[0004] In the prior art, during the process of welding the centering bracket to the anchor rod, the worker usually holds the centering bracket and presses the centering bracket onto the anchor rod during the welding process. During this process, the angle of the centering bracket may be easily offset due to the shaking of the worker, thereby causing the welding angle to fail to meet the design requirements and be unqualified. In addition, during the welding process, since the worker needs to hold the centering bracket, it is easy for metal droplets during the welding process to splash onto the arm, causing injury to the worker. Summary of the invention

[0005] The present invention provides an anchor rod steel bar welding device, aiming to solve the technical problems in the related technology that workers are required to hold a centering bracket, which may easily cause harm to the workers, and the angle of the centering bracket may be offset due to the shaking of the workers, thereby making the welding angle fail to meet the design requirements and be unqualified.

[0006] An anchor rod steel bar welding device comprises a frame, a clamping mechanism for clamping the anchor rod is arranged on the frame, a rotating mechanism is arranged on the clamping mechanism, and the rotating mechanism is used to rotate the anchor rod clamped by the clamping mechanism, and further comprises:

[0007] The feeding mechanism comprises a silo for storing the bracket, a feeding assembly and a pushing assembly arranged on the frame. A discharge port is provided between the left side of the bottom surface of the silo and the left end in the silo, a feeding port is provided on the upper end surface of the silo, and the pushing assembly is used to push the bracket in the silo to the discharge port. The feeding assembly comprises a limit plate hinged on the left side of the discharge port and a pressure plate slidably arranged in the discharge port for pressing the bracket on the anchor rod. When the bracket at the discharge port is welded to the anchor rod, the clamping mechanism clamps the anchor rod to rotate, so that the bracket on the anchor rod rotates and squeezes the limit plate. When the limit plate rotates, the pressure plate moves upward in the discharge port. When the pressure plate moves to the top of the bracket in the silo, the bracket in the silo slides to the discharge port. When the limit plate is reset, the pressure plate presses the bracket in the discharge port downward, so that the bracket abuts against the anchor rod.

[0008] The effect is that by setting up a silo, multiple brackets can be placed in the silo, and by setting up a material unloading component, after welding a bracket, a new bracket can be automatically placed on the anchor rod by rotating the anchor rod, and there is no need for workers to manually support the bracket.

[0009] Preferably, the pushing assembly includes a push plate and an elastic member slidably arranged in the silo along the left and right directions, the push plate is used to push the bracket in the silo to the discharge port, and an elastic member is arranged between the push plate and the silo, which is used to make the push plate located at the leftmost end in the silo.

[0010] The effect is that the bracket in the silo is sent into the discharge port.

[0011] Preferably, a support assembly is further provided in the silo, and the support assembly includes two sliders slidably arranged on the right end plate along the front-rear direction and two support rods slidably arranged on the two sliders along the up-down direction respectively.

[0012] The effect is that the brackets in the silo are arranged neatly, making it easier for the push plate to send the brackets into the discharge port.

[0013] Preferably, a second elastic member for resetting the limit plate is provided at the hinge shaft of the limit plate.

[0014] The effect is that the limit plate can be automatically reset.

[0015] Preferably, an adjustment plate 1 and an adjustment plate 2 which slide in the left-right direction are provided at the discharge port, and the bracket is located between the adjustment plate 1 and the adjustment plate 2.

[0016] The effect is that the spacing between the first adjusting plate and the second adjusting plate can be adjusted to accommodate brackets of different sizes.

[0017] Preferably, the rotating mechanism includes a rotating ring rotatably mounted on the frame and three push rods slidably mounted on the rotating ring along the radial direction of the rotating ring. When the rotating ring rotates, the push rods abut against the right side of the welded bracket.

[0018] Preferably, an inclined plate abutting against the pressure plate is installed on the right end surface of the rotating ring, and when the rotating ring rotates, the pressing plate is pushed to move upward in the discharge port through the inclined plate.

[0019] Preferably, a support mechanism for supporting the anchor rod is provided in front of the silo and behind the clamping mechanism, and the support mechanism includes a telescopic plate slidably installed in the frame along the front-rear direction and a support wheel installed on the telescopic plate for supporting the anchor rod.

[0020] By adopting the above technical solution, the beneficial effects of the present invention are as follows:

[0021] By setting up a silo, multiple brackets can be stored at a time, and during the welding process, the unloading assembly can press the bracket onto the anchor rod without the need for manual support from workers, thereby improving the safety of welding. In addition, by setting a telescopic block on the mounting ring, it can remind workers to turn the angle of the anchor rod, thereby improving the welding accuracy of the bracket.

[0034] Embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to be used to explain the present invention, but should not be understood as limiting the present invention.

[0035] like Figure 1 As shown, the present invention is an anchor bar steel bar welding device, comprising a frame 1, a clamping mechanism 2, a rotating mechanism 3, a feeding mechanism 4 and two groups of supporting mechanisms 5, wherein the clamping mechanism 2 is arranged at the rear end of the frame 1, and is used to clamp the anchor bar 6, the rotating mechanism 3 is arranged at the front side of the clamping mechanism 2, and is used to rotate the anchor bar 6, the feeding mechanism 4 is arranged on the frame 1, and is located at the front side of the rotating mechanism 3, and is used to store a plurality of brackets 7, and the brackets 7 are placed on the anchor bar 6, and the supporting mechanism 5 is provided with two groups, which are respectively located at the front and rear sides of the feeding mechanism and the clamping mechanism 2, and are used to support the anchor bar 6, and the welding When connecting the bracket 7, first place the anchor rod 6 on the supporting mechanism 5 on the rear side, then push the anchor rod 6 forward and pass through the clamping mechanism 2, so that the front end of the anchor rod 6 is placed on the supporting mechanism 5 on the front side, and then the unloading mechanism 4 places the bracket 7 stored inside it on the anchor rod 6, and then the worker starts to weld the anchor rod 6 and the bracket 7. After welding one bracket 7, the rotating mechanism 3 drives the anchor rod 6 to rotate 120°, and then the unloading mechanism 4 places the new bracket 7 on the anchor rod 6 again. After welding three brackets 7, move the anchor rod 6 forward for a distance and repeat the above process.

[0036] like Figure 1-Figure 10As shown, the clamping mechanism 2 includes a mounting ring 21, three clamping wheels 22 and an adjusting ring 23. The frame 1 as a whole is composed of a horizontal plate and a vertical plate located at the rear end of the horizontal plate. A mounting hole that runs through the front and rear is opened on the vertical plate. The mounting ring 21 is rotatably installed on the rear half of the mounting hole. The clamping wheel 22 is composed of a mounting seat and a plurality of rollers 1 rotatably installed on the mounting seat, and the axis of the roller 1 is perpendicular to the axis of the mounting ring 21. The left end surface of the mounting ring 21 is provided with three slide grooves 1 along the radial direction of the mounting ring 21. The three slide grooves 1 are evenly spaced around the axial direction of the mounting ring 21. The three clamping wheels 2 2 are respectively slidably installed in the slide groove 1, and a tension spring 1 (not shown in the figure) is arranged between the mounting seat and the mounting ring 21, and the tension spring 1 is used to make the mounting seat located at the outermost side of the slide groove 1. A ring groove with a diameter larger than the mounting hole is provided on the rear end surface of the vertical plate, and the adjusting ring 23 is installed in the ring groove by screw thread rotation. An end plate is provided at the rear end of the adjusting ring 23, and a through hole 1 with a diameter smaller than the diameter of the mounting ring 21 is provided on the end plate. The through hole 1 is used for the anchor rod 6 to pass through. An inclined surface 1 abutting against the edge of the through hole 1 is provided on the rear end surface of the mounting seat, and a plurality of handles 1 24 are installed on the rear end surface of the end plate.

[0037] After the front end of the anchor rod 6 is placed on the front support mechanism 5, the worker holds the handle 24 and drives the adjusting ring 23 to rotate by turning the handle 24. When the adjusting ring 23 rotates clockwise, the adjusting ring 23 moves forward in the annular groove. At this time, the edge of the through hole 1 abuts against the inclined surface 1 of the mounting seat, so that the mounting seat gradually moves inward in the slide groove 1 until the clamping wheel 22 is pressed against the anchor rod 6.

[0038] like Figure 4-Figure 8As shown, the rotating mechanism 3 includes a rotating ring 31 and three sliders 1 32 arranged in a circular array in the rotating ring 31. The rotating ring 31 is rotatably installed in the front half of the mounting hole, and the front end of the rotating ring 31 extends out from the front end of the mounting hole. The rotating ring 31 is coaxially provided with a through hole 2 that penetrates along the front-to-back direction. The through hole 2 is used for the anchor rod 6 to pass through. The rotating ring 31 is provided with three slide grooves 2 in the radial direction of the rotating ring 31 in the through hole 2. The three sliders 1 32 are slidably installed in the three slide grooves 2 respectively, and a compression spring 1 (not shown in the figure) is arranged between the slider 1 32 and the rotating ring 31. The compression spring 1 is used to make the three sliders 1 32 approach and abut against each other. The rear end surface of the slider 1 32 is provided with an inclined surface 2. When the anchor rod 6 passes through the clamping wheel 22, it abuts against the three inclined surfaces 2. When the anchor rod 6 continues to move forward, the front end of the anchor rod 6 pushes the three sliders 32 away from each other through the inclined plane 2 until the front end of the anchor rod 6 passes over the inclined plane 2, and the slider 32 abuts against the anchor rod 6. A push rod 33 extending forward is installed on the front end surface of the slider 32, and the push rod 33 is located on the slider 32 at the end where the slider 32 abuts against the anchor rod 6. When the slider 32 abuts against the anchor rod 6, the push rod 33 also abuts against the anchor rod 6. An arc groove is coaxially provided on the right end surface of the mounting ring 21, and a connecting rod 34 sliding in the arc groove is installed on the left end surface of the swivel 31. A compression spring 3 is arranged between the connecting rod 34 and the mounting ring 21. The compression spring 3 is used to make the connecting rod 34 located at the right end of the arc groove. A plurality of handles 2 35 are installed on the outer circumferential surface of the swivel 31.

[0039] After welding a bracket 7, the worker drives the swivel 31 to rotate by pulling the second handle 35. The connecting rod 34 on the swivel 31 first moves to the leftmost end of the arc groove and then drives the mounting ring 21 to rotate. When the connecting rod 34 moves to the leftmost end of the arc groove, the push rod 33 abuts against the right side of the bracket 7. When the swivel 31 continues to rotate, the push rod 33 pushes the bracket 7 to rotate, thereby driving the anchor rod 6 to rotate. An elastic expansion block 25 that expands and contracts along the radial direction of the mounting ring 21 is installed on the outer circumferential surface of the mounting ring 21. The outer side of the expansion block 25 is a ball On the mounting hole, three limiting holes (not shown in the figure) for cooperating with the telescopic block 25 are provided at equal intervals around the axis of the mounting hole. When the worker drives the swivel 31 to rotate by pulling the handle 2 35, the connecting rod 34 first moves to the left end in the arc groove, and then the connecting rod 34 drives the mounting ring 21 to rotate. At this time, the telescopic block 25 first retracts into the mounting ring 21. When the mounting ring 21 rotates 120°, the telescopic block 25 is aligned with the limiting hole again. At this time, the worker stops rotating the swivel 31 after feeling that the resistance to the rotation of the swivel 31 increases again.

[0040] like Figure 1-Figure 5As shown, the unloading mechanism 4 includes a silo 41, a pushing assembly, a supporting assembly and a unloading assembly. A feed port is provided on the upper end surface of the silo 41, and a discharge port is provided between the left side of the bottom surface of the silo 41 and the left end in the silo 41. The pushing assembly includes a push plate 42 and an elastic member 1. The push plate 42 is slidably installed in the silo 41 along the left and right directions. The elastic member 1 is a compression spring 2. The two ends of the compression spring 2 are respectively connected to the push plate 42 and the silo 41. The compression spring 2 is used to make the push plate 42 located at the leftmost end in the silo 41. The supporting assembly is arranged in the silo 41 for supporting the bracket 7 so that the bracket 7 is arranged neatly. The unloading assembly is arranged at the discharge port for discharging the bracket 7 one by one from the discharge port.

[0041] like Figure 2-Figure 5 As shown, the supporting assembly includes two sliders 43 and two supporting rods 44. A slide rail matching with the slider 43 is provided on the right end surface in the silo 41. A lead screw 45 extending in the front-to-back direction is installed in the slide rail, and the front end of the lead screw 45 passes through the silo 41 forwardly. A protrusion 1 for enabling a worker to rotate the lead screw 45 is installed at the front end of the lead screw 45. The thread on the lead screw 45 is distinguished by the middle surface of the silo 41 in the front-to-back direction. The threads on the front and rear sides of the middle surface have opposite rotation directions. The two sliders are respectively mounted on two sections of the thread of the lead screw 45 with opposite rotation directions. The two supporting rods 44 extend in the left-right direction in the silo 41. The right ends of the two supporting rods 44 are respectively slidably installed on the two sliders 43 in the up-down direction. A lead screw 46 extending in the up-down direction is installed on the slider 43, and the upper end of the lead screw 46 passes through the silo 41 upwardly, and a protrusion 2 for enabling a worker to rotate the lead screw 46 is installed at the upper end of the lead screw 46.

[0042] like Figure 2-Figure 5As shown, the material unloading assembly includes an adjusting plate 1 47, an adjusting plate 2 48, a limiting plate 49 and a pressing plate 410. The adjusting plate 1 47 is slidably installed in the silo 41 along the left-right direction on the left side of the material discharge port. The adjusting plate 2 48 is slidably installed in the left-right direction at the left end of the bottom surface of the silo 41, and the upper end surface of the adjusting plate 2 48 is flush with the bottom surface in the silo 41. The front and rear ends of the lower end surface of the adjusting plate 1 47 are installed with connecting plates extending downward. A lead screw 3 411 extending in the left-right direction is installed on the lower silo plate of the silo 41, and the lead screw 3 411 passes through the adjusting plate 1 47 and the adjusting plate 2 48 at the same time. A protrusion 3 for enabling a worker to rotate the lead screw 3 411 is installed on the left end of the lead screw 3 411. Two sections of threads with opposite rotation directions are arranged on the lead screw 3 411. The adjusting plate 1 47 and the adjusting plate 2 48 are respectively installed on the two sections of threads with opposite rotation directions. When the lead screw 3 411 rotates forward, the adjusting plate 1 47 and The adjusting plates 48 are close to each other, and the limit plate 49 is hinged at the lower end of the adjusting plate 47. An elastic member 2 is provided at the hinge axis of the limit plate 49 for resetting the limit plate 49. The elastic member 2 is a torsion spring (not shown in the figure). The two ends of the torsion spring are respectively connected to the limit plate 49 and the adjusting plate 47. The pressing plate 410 is slidably installed in the discharge port along the up and down directions. The front and rear bin plates of the silo 41 are respectively provided with slide grooves 3. The front and rear ends of the pressing plate 410 are slidably installed in the slide grooves 3, and the front and rear ends of the pressing plate 410 extend out of the silo 41 respectively. A tension spring 2 (not shown in the figure) is installed in the slide groove 3. The two ends of the tension spring 2 are respectively connected to the pressing plate 410 and the silo 41. The tension spring 2 is used to make the pressing plate 410 located at the lowermost side of the discharge port. Three inclined plates 37 for abutting against the pressing plate 410 are installed on the front end surface of the swivel 31, and a handle 3 412 is installed on the upper end surface of the pressing plate 410.

[0043] When one side of the bracket 7 is welded, the worker rotates the swivel 31. After the connecting rod 34 abuts against the leftmost end of the arc groove, the push rod 33 abuts against the rear side of the bracket 7. Then the push rod 33 pushes the bracket 7 to rotate, thereby driving the anchor rod 6 to rotate. When the bracket 7 rotates, it pushes the limit plate 49 to deflect to the left. At the same time, the inclined plate 37 on the swivel 31 pushes the pressure plate 410 to move upward. When the pressure plate 410 moves to the top of the bracket 7 in the silo 41, the bracket 7 in the silo 41 moves to the discharge port under the push of the push plate 42. After the pressure plate 410 passes over the inclined plate 37 and the anchor rod 6, the pressure plate 410 presses the new bracket 7 in the discharge port downward, so that the new bracket 7 abuts against the anchor rod 6.

[0044] like Figure 1 , Figure 5 As shown, the support mechanism 5 includes a telescopic plate and a support wheel. The telescopic plate is slidably installed in the frame 1 along the front-rear direction. The support wheel includes a base and a roller 2 rotatably installed on the upper end of the base. The axis of the roller 2 extends along the left-right direction. A telescopic rod and a locking bolt that are telescopic along the up-and-down direction are provided on the base. The locking bolt is used to lock the telescopic rod.

[0045] The specific working principle of the present invention is:

[0046] Before the initial welding of the bracket 7, first rotate the lead screw 1 45 and the lead screw 2 46 to adjust the position of the support rod 44 so that the support rod 44 is located at the top of the inner side of the two oblique rods on the bracket 7, then rotate the lead screw 3 411 to adjust the spacing between the adjustment plate 1 47 and the adjustment plate 2 48 so that the left and right ends of the bracket 7 are respectively in contact with the adjustment plate 1 47 and the adjustment plate 2 48, then pull the push plate 42 to the right and place multiple brackets 7 on the support rod 44 in the silo 41, then place the front end of the anchor rod 6 on the roller 2 on the rear side, and then push the anchor rod 6 to move forward and pass through the clamping wheel 22 and the swivel 31 , until the front end of the anchor rod 6 is placed on the roller two on the front side, then turn the adjusting ring 23, after the three clamping wheels 22 are in contact with the anchor rod 6, adjust the height of the telescopic rod to make the height of the support wheel match the height of the anchor rod 6, and then pull the handle three 412 upwards to make the pressure plate 410 move upward in the discharge port to above the bracket 7 in the silo 41, and then make the push plate 42 push the bracket 7 into the discharge port, and then release the handle three 412, the pressure plate 410 presses the bracket 7 in the discharge port downward, so that the bracket 7 is in contact with the anchor rod 6, and the worker begins to weld the contact part between the bracket 7 and the anchor rod 6.

[0047] After welding the first bracket 7, the worker rotates the swivel 31. After the connecting rod 34 abuts against the leftmost end of the arc groove, the push rod 33 abuts against the rear side of the bracket 7. Then the push rod 33 pushes the bracket 7 to rotate, thereby driving the anchor rod 6 to rotate. When the bracket 7 rotates, the limit plate 49 is pushed to the left to deflect. At the same time, the inclined plate 37 on the swivel 31 and the anchor rod 6 push the pressure plate 410 to move upward. When the pressure plate 410 moves to the top of the bracket 7 in the silo 41, the bracket 7 in the silo 41 moves to the discharge port under the push of the push plate 42. After the pressure plate 410 passes over the inclined plate 37 and the anchor rod 6, the pressure plate 410 presses the new bracket 7 in the discharge port downward, so that the new bracket 7 abuts against the anchor rod 6. After the anchor rod 6 rotates 120°, the swivel 31 is stopped, and then the second bracket 7 is welded. When the welding is completed again, the swivel 31 is rotated 120° again, and finally the third bracket 7 is welded.

[0048] After the third bracket 7 is welded, the swivel 31 is first rotated to allow a new bracket 7 to enter the discharge port, and then the anchor rod 6 is pushed forward.

[0049] Although the embodiments of the present invention have been shown and described above, it is to be understood that the above embodiments are exemplary and are not to be construed as limitations of the present invention. A person skilled in the art may change, modify, replace and vary the above embodiments within the scope of the present invention.
