Description

Technical Field

[0001] This utility model relates to the field of anchor bolt production, and in particular to an adjustable anchor bolt production and welding equipment. Background Technology

[0002] Adjustable anchor bolts typically include an anchor bolt body, an adjustable connecting sleeve, an anchor head, a washer, a hexagonal nut, etc. The length and angle of the anchor bolt can be adjusted according to construction requirements through the connecting sleeve or anchor head to adapt to different geological conditions and construction space. Welding the anchor head to one end of the anchor bolt is a key step in anchor bolt production.

[0003] According to the patent document with publication number CN218745750U, the patent document describes a process where a ring is placed on a base, and a motor drives a power plate to rotate, which in turn drives multiple sets of positioning claws to move closer together and fix the ring. An anchor rod is placed vertically between multiple sets of clamping plates, with the bottom end of the anchor rod contacting the ring. A telescopic rod extends and pushes the clamping plates closer together to clamp and fix the anchor rod. The orientation of the welding head is adjusted by rotating the telescopic rod, and the extension of the telescopic rod pushes the welding head to move and contact the connection point between the anchor rod and the ring. A motor drives a gear to rotate, and the gear meshes with the meshing teeth, causing the arc frame to rotate around the anchor rod, thereby achieving the welding of the anchor rod and the ring.

[0004] The patent document states that during the process of moving the welding head to perform circumferential welding on the anchor rod, the sudden local heating caused by welding can create an excessive temperature gradient at the anchor rod weld, resulting in excessive thermal stress on the anchor rod, which may lead to anchor rod deformation.

[0031] The present invention will be further described below with reference to the accompanying drawings:

[0032] like Figures 1-6 As shown, an adjustable anchor bolt production welding device includes a support plate 1, a welding mechanism, and a preheating mechanism.

[0033] The support plate 1 is arranged at the front and rear. Two clamping mechanisms are provided on the top of the support plate 1. These mechanisms clamp the anchor rod and anchor head respectively, causing them to rotate synchronously. Each clamping mechanism includes two fixed plates 201 and four clamping plates 203. The two fixed plates 201 are fixed to the top of the support plate 1, and a rotating ring 202 is rotatably connected between the two fixed plates 201. Each clamping plate 203 is fixedly installed inside the rotating ring 202 by two screws 204. One end of each screw 204 is rotatably connected to a clamping plate 203, and the other end is threaded to the rotating ring 202. A first gear 205 is fixed to the outer wall of the rotating ring 202, and a second gear 206 meshes with the rear of the first gear 205. The two gears are connected by a rotating shaft. Two gears 206 are fixedly connected. A motor is fixed to the input end of the rotating shaft. The anchor head welding end is placed between the four corresponding clamping plates 203 with the welding head 303 facing it. The two screws 204 corresponding to the clamping plates 203 are rotated, which in turn drives the clamping plates 203 to move closer to the anchor head. Thus, the four clamping plates 203 clamp the anchor head. The anchor rod welding end is passed through the four corresponding clamping plates 203 and corresponds to the anchor head welding end. The above operation is repeated so that the four clamping plates 203 clamp the anchor rod. The rotating shaft is driven by the motor to rotate, which in turn drives the two second gears 206 to rotate synchronously. The second gears 206 mesh with the first gears 205, which in turn drives the two first gears 205 and the two rotating rings 202 to rotate synchronously, thereby driving the anchor rod and anchor head to rotate synchronously.

[0034] The welding mechanism is located on the top of the support plate 1. The welding mechanism is used to weld the anchor rod and the anchor head. The welding mechanism includes a fixing frame 301 and a welding head 303. The fixing frame 301 is fixed on the top of the support plate 1. The welding head 303 slides up and down at the bottom of the fixing frame 301 through the drive assembly. The welding head 303 is located between two rotating rings 202. Two induction coils 403 are located on the lower side of the welding head 303. The welding head 303 is driven down by the hydraulic cylinder 302 to the welding point of the anchor head and the anchor rod to start welding.

[0035] The preheating mechanism includes a support frame 401, two induction coils 403, and an adjustment assembly. The support frame 401 is fixed to the top of the support plate 1. A connecting rod 405 is rotatably connected to the top of the support frame 401. An induction power supply 402 is hinged to both the front and rear sides of the connecting rod 405. The induction coils 403 are fixed to the top of the induction power supply 402. The two induction coils 403 are combined into a circle. The induction coils 403 are curved and wavy. The two induction coils 403 are arranged in an alternating pattern. The induction power supply 402 provides power to the induction coils 403. The induction coils 403 convert electrical energy into heat energy to preheat the anchor rod and anchor head, reduce the temperature gradient during welding, reduce thermal stress, and prevent anchor rod deformation.

[0036] An adjustment assembly is located between the two inductive power sources 402 and the support frame 401. This assembly controls the opening and closing overlap of the two inductive coils 403. The adjustment assembly consists of two electrically operated telescopic rods 404, which are fixed to the front and rear sides of the support frame 401 respectively. The telescopic ends of the electric telescopic rods 404 are hinged to the bottom of the inductive power sources 402. The drive assembly is a hydraulic cylinder 302, which is fixed to the top of the fixed frame 301. The piston end of the hydraulic cylinder 302 passes through the fixed frame 301 and is fixedly connected to the welding head 303. The two electric telescopic rods 404 push the cylinder... Two induction power sources 402 rotate about the connecting rod 405 towards the anchor rod, thereby causing the two induction coils 403 to cross and approach each other. The overlap of the two induction coils 403 is adjusted according to the diameter of different anchor rods and anchor heads, thereby adjusting the distance between the induction coils 403 and the welding ends of the anchor rods and anchor heads, improving the heating effect and saving electricity. After preheating, the two induction power sources 402 are pulled by two electric telescopic rods 404 to rotate about the connecting rod 405 away from the anchor rod, thereby causing the two induction coils 403 to move away from each other and no longer cross, so that the welding head 303 can be moved out of position.

[0037] Working principle: Place the anchor head welding end facing the welding head 303 between the four corresponding clamping plates 203, rotate the two screws 204 corresponding to the clamping plate 203, thereby driving the clamping plate 203 closer to the anchor head, so that the four clamping plates 203 clamp the anchor head. After passing the anchor rod welding end through the four corresponding clamping plates 203, it corresponds to the anchor head welding end. Repeat the above operation so that the four clamping plates 203 clamp the anchor rod.

[0038] After the anchor rod and anchor head are clamped and positioned, two electric telescopic rods 404 drive two induction power supplies 402 to rotate towards the anchor rod with the connecting rod 405 as the axis. This causes the two induction coils 403 to cross and approach each other. The overlap of the two induction coils 403 is adjusted according to the diameter of different anchor rods and anchor heads, thereby adjusting the distance between the induction coils 403 and the welding ends of the anchor rod and anchor head, improving the heating effect and saving electricity. The induction power supply 402 provides power to the induction coils 403, and the induction coils 403 convert electrical energy into heat energy to preheat the anchor rod and anchor head, reduce the temperature gradient during the welding process, reduce thermal stress, and avoid anchor rod deformation.

[0039] After the anchor rod and anchor head are preheated, two electric telescopic rods 404 pull two induction power supplies 402 to rotate away from the anchor rod around the connecting rod 405. This causes the two induction coils 403 to move away from each other and no longer cross, allowing the welding head 303 to move out of position. The hydraulic cylinder 302 drives the welding head 303 to move downward to the welding point of the anchor head and anchor rod. The motor drives the rotating shaft to rotate, which in turn drives the two second gears 206 to rotate synchronously. The second gears 206 mesh with the first gears 205, which in turn drives the two first gears 205 and the two rotating rings 202 to rotate synchronously, thereby driving the anchor rod and anchor head to rotate synchronously. The welding head 303 then welds the rotating anchor rod and anchor head.

[0040] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
