Abstract
Description
Technical Field
[0001] This invention relates to the field of processing equipment for tower crane fixing devices, and specifically to an automatic processing device for adjustable wall-mounted poles. Background Technology
[0002] Modern tower cranes require stacking multiple standard sections to increase the height of the crane's boom. However, the higher the standard section, the greater its torque, and consequently, the lower its stability. Currently, wall-mounted rods are used to fix the standard sections to the outer wall, reducing their torque. Since the distance between the standard section and the outer wall is uncertain, the wall-mounted rods are typically manufactured with adjustable lengths. These rods are currently manufactured by manual welding. This involves placing two channel steel plates opposite each other, using a mold to evenly place perforated sections between the two plates, and then welding them manually. This manual stacking process is time-consuming and cannot be continuous; each welding mold can only process one wall-mounted rod at a time. Stacking, welding, and unloading must be performed on each mold before the next welding operation can begin. This process is difficult and inefficient. Summary of the Invention
[0003] To address the shortcomings of the existing technology, this invention proposes an automatic processing device for adjustable wall-mounted rods, which enables automatic adjustment and welding of adjustable wall-mounted rods. This reduces the labor intensity of workers, improves processing efficiency, and realizes the transformation from manual to intelligent processing.
[0004] To achieve the above objectives, the present invention provides an automatic processing device for adjustable wall-mounted rods, comprising a channel steel conveying mechanism, a connecting plate conveying mechanism, and a moving welding mechanism. The channel steel conveying mechanism is installed on the ground to convey vertically opposed channel steels. Connecting plate conveying mechanisms are installed on both sides of the channel steel conveying mechanism to convey multiple connecting plates to both sides of the channel steel. Moving welding mechanisms are installed above and below each connecting plate conveying mechanism to weld the connecting plates to the channel steel. The channel steel conveying mechanism includes a bracket, limiting rollers, a conveying roller, and a pushing component. The bracket consists of two brackets installed vertically opposite each other, allowing the two channel steels to slide on the brackets. The brackets limit the distance between the two channel steels. Multiple limiting rollers are installed between the two brackets, limiting the movement of the channel steels at their edges. A pushing component is installed at one end of the bracket to push the channel steel onto the bracket for conveying.
[0005] Preferably, the pushing assembly includes a placement frame, a baffle, a push plate, and a pushing hydraulic cylinder. The placement frame is divided into two layers, arranged vertically. A baffle is provided on one side of the placement frame. When one side of the channel steel contacts the baffle, it is opposite to the bracket. The placement frame and the bracket are perpendicular to each other. A push plate is provided at the end of the placement frame away from the bracket. A pushing hydraulic cylinder installed on the ground is provided at the end of the push plate. The pushing hydraulic cylinder pushes the channel steel on the placement frame onto the bracket. Multiple conveying rollers arranged side by side are provided on the top surface of each bracket. The channel steel is placed on the conveying rollers for conveying. An mounting plate is fixed below the top bracket. Multiple sets of limiting rollers that contact the inner wall of the channel steel are installed on the mounting plate through bearings. Multiple through holes are opened at the end of the top bracket. The distance between two through holes is the length of the channel steel. A pin that is telescopically extended by a cylinder is provided on the outside of each through hole and the pin extends into the through hole. The first end of each bracket and the end of the bottom bracket are installed on the ground through columns.
[0006] Preferably, the connecting plate conveying mechanism includes a conveying chain, conveying sprockets, a support plate, and positioning posts. Two support plates are located on both sides of a bracket. On each support plate, two sets of motor-driven conveying sprockets are mounted via bearings. Each set of conveying sprockets consists of two vertically arranged conveying sprockets. The two sets of conveying sprockets mesh with two vertically arranged conveying chains. Multiple equally spaced sleeves are fixed to the two conveying chains. A positioning post that slides within each sleeve is installed, and a limit plate is fixed to the positioning post. A return spring is fitted onto the positioning post, and both ends of the return spring are fixed to the sleeve and the limit plate, respectively. The positioning post and the connecting plate have a through hole shaft fit together. The outer wall of the positioning post contacts the inner wall of the through hole of the connecting plate. The inner side of the conveyor chain has a push assembly, which includes a flat push plate and a flat push cylinder. The cylinder body of the flat push cylinder is mounted on the support plate. The piston rod of the flat push cylinder is fixed to the flat push plate. The positioning post is pushed outward by the flat push plate. An infrared detection assembly is fixed on the support plate. The infrared detection assembly is an infrared reflection sensor and the infrared reflection sensor faces the connecting plate fitted on the positioning post. This achieves the limitation of the connecting plate. The infrared reflection sensor is connected to the flat push cylinder and the motor respectively.
[0007] Preferably, the mobile welding mechanism includes a linear motor and a welding gun. Each pallet is equipped with two sets of linear motors arranged vertically. The stator rail of the linear motor is mounted on the pallet via a bracket. The moving slide seat is fixed with the welding gun, and the two welding guns on the pallet respectively weld at the contact points of the connecting plate and the channel steel.
[0008] Compared with the prior art, the advantages of the present invention are: it realizes the automatic adjustment and welding of adjustable wall-mounted rods, thereby reducing the labor intensity of workers and improving processing efficiency, realizing the transformation from manual to intelligent processing.

[0016] The invention will now be further described with reference to the accompanying drawings.
[0017] like Figure 1-6As shown, an automatic processing device for adjustable wall-mounted poles includes a channel steel conveying mechanism 1, a connecting plate conveying mechanism 2, and a moving welding mechanism 3. The channel steel conveying mechanism 1 is fixed to the ground by bolts, conveying vertically opposed channel steels. The connecting plate conveying mechanism 2 is bolted to the ground on both sides of the channel steel conveying mechanism 1, conveying multiple connecting plates to both sides of the channel steel. Moving welding mechanisms 3 are located above and below each connecting plate conveying mechanism 2, welding the connecting plates to the channel steel. The connecting plate conveying mechanism 2 conveys the connecting plates to both sides of the two channel steels, and then the moving welding mechanism 3 welds the connecting plates to the channel steel, thus forming the wall-mounted pole. The channel steel conveying mechanism 1 includes a bracket 1.1 and a limit switch. The system includes rollers 1.2, conveying rollers 1.3, and a pushing assembly 1.4. A bracket 1.1 (rectangular frame) consists of two brackets 1.1 positioned vertically opposite each other. Two channel steels slide on the brackets 1.1, which limit the distance between them. Multiple limiting rollers 1.2 are bolted between the two brackets 1.1, limiting the sides of the channel steel. The pushing assembly 1.4 is bolted to the ground at the right end of the bracket 1.1, pushing the channel steel onto the bracket 1.1 for transport. Since the pushing distance is consistent each time, the position of the left and right ends of the channel steel is defined. The channel steels with opposite openings are transported on the bracket 1.1, which separates the two channel steels.
[0018] The pushing component 1.4 includes a placement frame 1.5, a baffle 1.6, a push plate 1.7, and a pushing hydraulic cylinder 1.8. The placement frame 1.5 consists of two layers, arranged vertically. The bottom of the placement frame 1.5 is bolted to the ground. A baffle 1.6 extending upwards is welded to the rear side of the placement frame 1.5, providing a limiting position. When one side of the channel steel contacts the baffle 1.6, it aligns with the bracket 1.1. The placement frame 1.5 and the bracket 1.1 are perpendicular to each other. At the end of the placement frame 1.5 furthest from the bracket 1.1 (… A push plate 1.7 is provided at the right end of the placement rack 1.5. A pushing hydraulic cylinder 1.8, mounted on the ground, is fixed to the end of the push plate 1.7 by welding. The extension and retraction of the pushing hydraulic cylinder 1.8 pushes the channel steel on the placement rack 1.5 to the left. There are two push plates 1.7 and two pushing hydraulic cylinders 1.8, and the two push plates 1.7 are positioned opposite to the channel steel on the placement rack 1.5. The pushing hydraulic cylinder 1.8 pushes the channel steel on the placement rack 1.5 onto the bracket 1.1. Multiple side-by-side brackets are fixed to the top surface of each bracket 1.1 via a rotating shaft. The conveyor roller 1.3 facilitates the transport of the channel steel on the bracket 1.1. The channel steel is placed on the conveyor roller 1.3 for transport. A mounting plate 1.9 is fixed to the bracket 1.1 at the top using bolts. Multiple sets of limiting rollers 1.2, which contact the inner wall of the channel steel, are mounted on the mounting plate 1.9 via bearings. The limiting rollers 1.2 are located on the front and rear sides of the mounting plate 1.9, thus limiting the movement of the channel steel's front and rear sidewalls. Multiple through holes 1.10 are located at the end of the top bracket 1.1. The spacing between holes 1.10 is the length of the channel steel. On the outside of each through hole 1.10, there is a pin 1.11 that is telescopically extended by a cylinder and extends into the through hole 1.10 (the cylinder is fixed to the support frame by bolts, and the bottom of the support frame is fixed to the ground by bolts. In this way, the extension and retraction of the cylinder extends the pin 1.11 into the through hole 1.10 to support the bracket 1.1, which facilitates the clearance of the wall-mounted rod during transportation). The first end of each bracket 1.1 and the end of the bottom bracket 1.1 are installed on the ground by a column.
[0019] The connecting plate conveying mechanism 2 includes a conveying chain 2.1, conveying sprockets 2.2, a support plate 2.3, and positioning posts 2.4. Two support plates 2.3 are located on the front and rear sides of the bracket 1.1. Two sets of motor-driven conveying sprockets 2.2 are mounted on each support plate 2.3 via bearings. Each set of conveying sprockets 2.2 consists of two vertically arranged sprockets 2.2 (the two sprockets 2.2 pass through and are fixed to the output shaft of the motor, which drives them to rotate). The two sets of conveying sprockets 2.2 mesh with two vertically arranged conveying chains 2.1. Multiple equally spaced posts are fixed to the two conveying chains 2.1 by welding. The sleeve 2.5 is provided, and a positioning post 2.4 is provided in each sleeve 2.5 to slide within the sleeve 2.5. A limit plate 2.7 is fixed to the positioning post 2.4 by welding (when the connecting plate is sleeved on the positioning post 2.4, the connecting plate abuts against the limit plate 2.7, and the bottom of the limit plate 2.7 rests on the support plate 2.3). A return spring 2.6 is sleeved on the positioning post 2.4, and the two ends of the return spring 2.6 are fixed to the sleeve 2.5 and the limit plate 2.7 by welding respectively (the return spring 2.6 pulls the limit plate 2.7 closer to the sleeve 2.5). The positioning post 2.4 and the through hole 1.10 of the connecting plate are matched. The outer wall of the positioning column 2.4 contacts the inner wall of the through hole 1.10 of the connecting plate. The inner side of the conveyor chain 2.1 is pushed by the push assembly 2.8, which includes a flat push plate 2.9 and a flat push cylinder 2.10. The cylinder body of the flat push cylinder 2.10 is bolted to the support plate 2.3. The piston rod of the flat push cylinder 2.10 is welded to the flat push plate 2.9, which pushes the positioning column 2.4 outward. When the positioning column 2.4 moves outward, the connecting plate adheres to the outer wall of the channel steel. An infrared detection assembly 2.11 (infrared reflection sensor) is bolted to the support plate 2.3. The infrared detection component 2.11 is an infrared reflection sensor, which faces the connecting plate fitted onto the positioning post 2.4. When the infrared reflection is reflected back by the connecting plate, it indicates that the connecting plate has moved to the position of the infrared reflection sensor. This causes the horizontal push cylinder 2.10 to lift, and the positioning post 2.4 to extend outward, so that the connecting plate fits against the outer wall of the channel steel, thus limiting the position of the connecting plate. The infrared reflection sensor is connected to both the horizontal push cylinder 2.10 and the motor. Loading the connecting plate simply involves fitting it onto the positioning post, with the bottom of the connecting plate contacting the top of the support plate to prevent rotation on the positioning post. This application primarily aims to achieve automatic welding of the connecting plate to the channel steel.
[0020] The mobile welding mechanism 3 includes a linear motor 3.1 and a welding gun 3.2. Two sets of linear motors 3.1 are fixed on each support plate 2.3 by connecting clamps. The stator rails of the linear motors 3.1 are mounted on the support plate 2.3 by brackets (the stator rails are located on the upper and lower sides of the support plate 2.3 respectively). The moving slide seat is fixed with the welding gun 3.2 and the two welding guns 3.2 on the support plate 2.3 respectively weld at the contact points of the connecting plate and the channel steel. The automatic welding of the welding gun 3.2 is realized by the movement of the linear motor 3.1.
