Description

Technical Field

[0001] This invention relates to the field of equipment technology for manufacturing utility poles, and more particularly to a welding device for steel cages in the processing of utility poles. Background Technology

[0002] A utility pole reinforcement cage is a three-dimensional mesh-like cylindrical structure made up of longitudinal reinforcement (main bars) and transverse reinforcement (stirrups or spiral bars) fixed by welding or binding. This reinforcement cage is placed in a mold, and then high-strength concrete is poured to finally form the prestressed concrete utility poles we see every day.

[0003] There are two types of steel cages on the market. The first type has a spiral bar rolled and welded around the outer surface of the main bar (outer hoop type), and the second type has several circular hoop bars welded on the inner surface of the main bar (inner support type). For the second type of steel cage with inner support, the existing welding equipment uses a conveying device to transport the steel bars one by one to the outer surface of the circular hoop, and then welds them one by one at one point. This welding method is inefficient. Summary of the Invention

[0004] This invention discloses a welding device for steel reinforcement cages in the processing of utility poles, which aims to solve the technical problem that the work efficiency and ease of operation need to be improved in the preparation of steel reinforcement cages for utility poles on the market.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: A welding device for processing steel reinforcement cages for utility poles includes several symmetrically distributed electrically controlled welding tables. A clamping mechanism for fixing the steel reinforcement is provided between the several groups of electrically controlled welding tables. The clamping mechanism and the electrically controlled welding tables are staggered. The clamping mechanism includes several bases evenly distributed between each group of electrically controlled welding tables. A stepper motor is fixedly installed on the top side of each base. A bidirectional lead screw is horizontally fixed at the output end of the stepper motor. A pair of clamps is sleeved on the outer side of the bidirectional lead screw. Several clamping components are slidably installed between the two clamps. The ends of each clamping component are rotatably connected by a hinge. The clamping mechanism is provided with an inner support mechanism for fixing the steel ring in the middle. The inner support mechanism includes a support fixedly installed on the ground. A horizontal frame is fixed in the middle of the support. The horizontal frame passes through several heads of the clamping mechanism in sequence. At the same time, several evenly distributed sleeves are sleeved on the outside of the horizontal frame. The clamping mechanism is used to quickly wrap the reinforcing bar around the outside of the inner support mechanism, and then the electric welding table is used to weld the reinforcing bar and the steel ring together.

[0006] By incorporating a clamping mechanism into an existing internally supported rebar cage processing technology, workers can install and fix all the rebars in one go using the flattened clamping mechanism. Then, the converging deformation of the clamping mechanism causes the rebars to wrap around the outside of the steel ring held by the additional internally supported mechanism, thus facilitating the initial positioning of the rebars and steel ring. Combined with an electrically controlled welding table, the rebars and steel ring are welded together as one unit. Unlike existing technologies, this equipment can significantly improve the convenience of internally supported rebar cage preparation, thereby greatly increasing production efficiency.

[0007] In a preferred embodiment, a plurality of evenly distributed toothed edges are fixedly welded to the back of each clamping member, gears are distributed in the middle of the base, the gears and the toothed edges are meshed and connected, and a geared motor is fixedly installed on the top of the base, the output end of the geared motor being fixedly connected to the gears.

[0008] By setting a base structure with a geared motor on the inner side of the electrically controlled welding table, under normal conditions, the clamps in the initial position drive several clamping components to flatten and distribute. The worker clamps and installs all the steel bars into the inside of the clamping components at once. Then, the stepper motor controls the bidirectional lead screw to drive the two clamps to move in the center. While moving, the flattened clamping components are pushed together to form a ring structure, so that all the steel bars are wrapped around the outside of the steel ring. With the help of the geared motor, the clamping components are driven to rotate by the gear teeth, and the position is adjusted to cooperate with the welding of the electrically controlled welding table to process the steel cage. Unlike the existing technology, this equipment can greatly improve the convenience of preparing the internally supported steel cage.

[0009] In a preferred embodiment, a plurality of elastic rods are fixedly installed on the outer side of each sleeve, and the elastic rods are compressed and supported on the outer side of the steel ring, so that each steel ring is symmetrically distributed with a set of electrically controlled welding tables.

[0010] By additionally setting a sleeve structure supported by a crossbeam on the inner side of the clamping mechanism, the elastic rod located on the outer side of the sleeve is used to support the steel ring, while not affecting the unloading of the steel ring after welding. This ensures the completeness of the equipment operation and improves the ease of operation.

[0011] In a preferred embodiment, a feeding assembly is provided on the opposite side of the internal support mechanism. The feeding assembly includes a guide rail fixedly installed on the ground. An electrically controlled slide is slidably installed on the top of the guide rail. The electrically controlled slide has several circular grooves evenly distributed inside, and each steel bar is slidably inserted into the inside of one of the circular grooves.

[0012] By incorporating an electrically controlled slide table structure that slides onto the top of the guide rail, the prepared steel cage is clamped using the circular groove in the middle of the electrically controlled slide table. The horizontal movement of the electrically controlled slide table then drives the steel cage to be automatically unloaded, thereby greatly improving the ease of operation of this equipment.

[0013] As can be seen from the above, the welding device for processing steel cages for utility poles provided by the present invention has the following technical effects.

[0014] By setting a base structure with a geared motor on the inner side of the electrically controlled welding table, under normal conditions, the clamp in the initial position drives several clamping components to flatten and distribute. The worker clamps and installs all the steel bars into the inside of the clamping components at once. Then, the centering movement of the clamp pushes the flattened clamping components to gather into a ring structure, which causes all the steel bars to be wrapped around the outside of the steel ring held by the additional inner support mechanism. With the geared motor, the clamping components are driven to rotate by the gear teeth, and the position is adjusted to cooperate with the welding of the electrically controlled welding table to process the steel cage. Unlike the existing technology, this equipment can greatly improve the convenience of preparing the inner support steel cage and thus greatly improve the production efficiency of traditional steel cages.

[0026] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0027] The present invention discloses a welding device for processing steel cages for utility poles, which is mainly used in the automated production of an internally supported steel cage.

[0028] Reference Figures 1 to 9 A welding device for processing steel reinforcement cages for utility poles includes several symmetrically distributed electrically controlled welding tables 1. A clamping mechanism 2 for fixing steel reinforcement is provided between the several groups of electrically controlled welding tables 1. The clamping mechanism 2 and the electrically controlled welding tables 1 are staggered. The clamping mechanism 2 includes several bases 201 evenly distributed between each group of electrically controlled welding tables 1. A stepper motor 202 is fixedly installed on the top side of each base 201. A bidirectional lead screw 203 is horizontally fixed at the output end of the stepper motor 202. A pair of clamps 204 are sleeved on the outer side of the bidirectional lead screw 203. Several clamping components 205 are slidably installed between the two clamps 204. The ends of each clamping component 205 are rotatably connected by a hinge. The clamping mechanism 2 is provided with an inner support mechanism 3 for fixing the steel ring in the middle. The inner support mechanism 3 includes a support 301 fixedly installed on the ground. A horizontal frame 302 is fixed in the middle of the support 301. The horizontal frame 302 passes through the heads of several clamping mechanisms 2 in sequence. At the same time, several evenly distributed sleeves 303 are sleeved on the outer side of the horizontal frame 302. The clamping mechanism 2 is used to quickly wrap the steel bar around the outside of the inner support mechanism 3, and then the steel bar and steel ring are welded together with the electric welding table 1.

[0029] In this embodiment: Under normal conditions, the clamping mechanism 2 is in a flattened state. At this time, the worker installs several steel rings to be welded onto the outside of the inner support mechanism 3, and simultaneously clamps several steel bars to be welded into the interior of the electric welding table 1. After completing the pre-installation process, the worker starts the clamping mechanism 2, causing the clamping mechanism 2 to gradually deform from a flattened state and wrap around the outside of the inner support mechanism 3 in a ring shape. This causes the steel bars located inside the clamping mechanism 2 to contact the steel rings located outside the inner support mechanism 3. At the same time, several electric welding tables 1 start to operate and weld the contact points of the steel bars and steel rings. During this process, the clamping mechanism 2 drives the steel bars and some of the welded steel rings to rotate slightly, thereby adjusting their positions until the electric welding table 1 completely welds the steel bars and steel rings together to form a steel cage.

[0030] Reference Figures 1 to 6 In a preferred embodiment, each clamping member 205 has several evenly distributed toothed edges 206 fixedly welded to its back. Gears 207 are distributed in the middle of the base 201. The gears 207 and the toothed edges 206 are meshed and connected. A reduction motor 208 is fixedly installed on the top of the base 201. The output end of the reduction motor 208 is fixedly connected to the gears 207.

[0031] Under normal conditions, the interconnected clamping components 205 are flattened. At this time, the worker installs several steel rings to be welded onto the outside of the inner support mechanism 3, and simultaneously inserts several reinforcing bars to be welded into the interior of each row of clamping components 205. After completing the preliminary installation, the worker starts the stepper motor 202, causing the rotating stepper motor 202 to drive the bidirectional lead screw 203 to rotate. The rotating bidirectional lead screw 203 drives the two clamps 204 to move in alignment. The moving clamps 204 push the clamping components 205, causing the clamping components 205 to gradually deform from a flattened state and wrap around the outside of the inner support mechanism 3 in a ring shape. This, in turn, causes the reinforcing bars located inside the clamping components 205 and the reinforcing bars located inside the inner support mechanism 3 to... The steel ring on the outer side of the inner support mechanism 3 contacts the steel ring, and at the same time, several electrically controlled welding tables 1 start to operate, welding the contact points of the steel bars and steel rings. During welding, the reduction motor 208 operates synchronously, driving the gear 207 to rotate. The rotating gear 207 drives several clamping components 205 to rotate slightly through the tooth edge 206, thereby adjusting their positions until the electrically controlled welding table 1 completely welds the steel bars and steel rings together to form a steel cage. After each operation of this equipment, the reduction motor 208 drives several clamping components 205 to reset and move through the gear 207 and tooth edge 206, ensuring that the clamping components 205 are centrally distributed between the two clamps 204.

[0032] The base 201 has an opening 2011 in the middle. The bottom of the clamp 204 is slidably distributed inside the opening 2011, providing space for the movement of the clamp 204. The clamp 204 at the end is fixedly installed with a positioning plate 209. When the worker installs the steel bars, he aligns the end of the steel bar with the positioning plate 209 and engages it inside the clamping member 205. The positioning plate 209 presses against the end of the steel bar, thereby making all the installed steel bars flush and ensuring the neatness of the finished steel cage.

[0033] Furthermore, the fixture 204 has a sliding groove 2041 inside, and the clamping member 205 is slidably installed inside the sliding groove 2041. When the fixture 204 moves, it will drive the clamping member 205 to move along the inside of the sliding groove 2041, thereby allowing several clamping members 205 to switch from a flat to a ring-shaped wrapping structure. The specific state is shown in the attached figure. Figure 6 and Figure 4 As shown.

[0034] Specifically, such as Figure 10 As shown, each clamping component 205 has a notch and slot 2051 inside. The reinforcing bar passes through the notch and slot 2051. The notch and slot 2051 can wrap more than 60% of the reinforcing bar. In this way, the reinforcing bar can be effectively prevented from falling off and the outer surface of the reinforcing bar can be in contact with the steel ring. In other embodiments, the reinforcing bar can be installed by passing it laterally through the notch slot 2051 or by inserting it longitudinally into the notch slot 2051. If the longitudinal insertion method is selected, an elastic element (such as a spring or rubber block) can be provided at the notch position of the notch slot 2051 to prevent the reinforcing bar from coming off the notch slot 2051 during the process of being wrapped by the clamping member 205.

[0035] Specifically, each elastic rod 304 has a flexible clip 305 fixedly installed at its end. The flexible clip 305 engages with the inside of the steel ring. The flexible clip 305, which can deform, combined with the elastic extension and contraction characteristics of the elastic rod 304, will not affect the normal feeding of the steel ring.

[0036] Reference Figures 1 to 2 , Figures 7 to 8 In a preferred embodiment, a plurality of elastic rods 304 are fixedly installed on the outer side of each sleeve 303. The elastic rods 304 are compressed and supported on the outer side of the steel ring, so that each steel ring is symmetrically distributed with a set of electrically controlled welding tables 1.

[0037] Under normal circumstances, the worker inserts several steel rings to be welded horizontally through the end of the crossbeam 302, moves a single steel ring to the outside of the sleeve 303, and at the same time, the elastic rod 304 is slightly contracted by compression, so that the steel ring is sleeved and fixed to the outside of several elastic rods 304, thereby fixing the steel ring. When the clamping component 205 gradually deforms from the flat state and wraps around the outside of the elastic rod 304 in a ring shape, the steel bar and the steel ring are squeezed and contacted.

[0038] Reference Figure 1 and Figure 9 In a preferred embodiment, a feeding assembly 4 is provided on the opposite side of the inner support mechanism 3. The feeding assembly 4 includes a guide rail 401 fixedly installed on the ground. An electrically controlled slide table 402 is slidably installed on the top of the guide rail 401. Several circular grooves 403 are evenly opened inside the electrically controlled slide table 402, and each steel bar is slidably inserted into the inside of a circular groove 403.

[0039] After the contact points of the reinforcing bars and steel rings are welded to form a reinforcing cage, the worker starts the electrically controlled slide 402, causing it to move along the top of the guide rail 401 toward the reinforcing cage. As it moves, the ends of the reinforcing bars pass through the inside of the circular groove 403. After the circular groove 403 connects with the ends of the reinforcing cage, the worker controls the electrically controlled slide 402 to move along the top of the guide rail 401 away from the clamping mechanism 2. As it moves, the finished reinforcing cage is peeled off from the outside of the clamping mechanism 2 and the inner support mechanism 3, completing the automatic unloading of the reinforcing cage.

[0040] Specifically, each circular groove 403 is equipped with an electrically controlled gripper 404 inside. The electrically controlled gripper 404 can clamp the outside of the steel bar, and then, in conjunction with the movement of the electrically controlled slide table 402, pull the finished steel bar cage to unload it (this is the prior art).

[0041] Working principle: During use, the worker horizontally inserts several steel rings to be welded into the end of the crossbeam 302, moves each steel ring to the outside of the sleeve 303, and simultaneously compresses the elastic rods 304, causing them to contract slightly, thus fixing the steel rings onto the outside of the elastic rods 304. The elasticity of the elastic rods 304 compresses and fixes the steel rings. Simultaneously, several reinforcing bars to be welded are sequentially inserted into the interior of each row of clamping components 205. After completing the preliminary installation, the worker starts the stepper motor 202, causing the rotating stepper motor 202 to drive the bidirectional lead screw 203 to rotate. The rotating bidirectional lead screw 203 drives the two clamps 204 to move in alignment. The moving clamps 204 push the clamping components 205, causing the clamping components 205 to gradually deform from a flattened state and wrap around the outside of the steel rings in a ring shape. This causes the reinforcing bars located inside the clamping components 205 and the steel rings located outside the sleeves to be welded. The steel ring on the outer side of the inner support mechanism 3 contacts the steel ring, and at the same time, several electrically controlled welding tables 1 start to operate, welding the contact points of the steel bars and steel rings. During welding, the reduction motor 208 runs synchronously, driving the gear 207 to rotate. The rotating gear 207 drives several clamping components 205 to rotate slightly through the tooth edge 206, thereby adjusting their positions until the electrically controlled welding table 1 completely welds the steel bars and steel rings together to form a steel cage. After that, the worker starts the electrically controlled slide table 402, causing the electrically controlled slide table 402 to move along the top of the guide rail 401 towards the steel cage. At the same time, the end of the steel bar passes through the inside of the circular groove 403. After connecting the circular groove 403 and the end of the steel cage, the worker controls the electrically controlled slide table 402 to move along the top of the guide rail 401 away from the clamping mechanism 2. At the same time, the finished steel cage is pulled and unloaded.

[0042] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
