Steel bar connecting equipment convenient to position for road and bridge construction

Abstract

The invention relates to the technical field of road and bridge construction, and particularly discloses road and bridge construction steel bar connecting equipment convenient to position, collecting parts are fixedly connected to the two sides of the middle of a main body, and a welding part is fixedly connected to the side, away from the collecting parts, of the middle of the main body. According to the road and bridge construction reinforcing steel bar connecting equipment convenient to position, the rotating wheels are arranged on the inner side of the feeding cylinder in a surrounding mode, and after reinforcing steel bars enter the feeding cylinder, the rotating wheels make multi-point contact with the surfaces of the reinforcing steel bars. The rotating wheels are uniformly distributed, not only convert sliding friction into rolling friction, but also play a role in auxiliary positioning. Due to the fact that the positions of the rotating wheels are relatively fixed, the reinforcing steel bars are jointly supported and guided by the rotating wheels in the moving process, and the position deviation of the reinforcing steel bars in the feeding cylinder is further limited. When the reinforcing steel bar moves forwards, if tiny radial deviation occurs, the rotating wheel can push the reinforcing steel bar back to the position relative to the center through contact force, and the reinforcing steel bar is always kept to move forwards stably in the axis direction of the feeding cylinder.

Description

Technical Field

[0001] The invention relates to the technical field of road and bridge construction, and in particular to a steel bar connection device for road and bridge construction which is easy to position. Background Art

[0002] The application of steel bar connection equipment in road and bridge construction has a profound industry background. With the acceleration of urbanization and the vigorous development of transportation infrastructure construction, the number and scale of road and bridge projects have continued to rise, which has put forward strict requirements on project quality, construction efficiency and structural stability. As a key load-bearing component of road and bridge structures, the quality of steel bar connections is directly related to the safety and durability of the entire project. In the early construction of roads and bridges, steel bar connections mostly relied on manual binding and simple welding methods. Manual binding is slow, labor-intensive, and has limited connection strength, which makes it difficult to meet the needs of large and complex road and bridge structures; simple welding technology is greatly affected by human factors, the quality is unstable, and it is prone to problems such as cold welding and desoldering. Construction in harsh environments is even more limited.

[0003] When steel bars are welded and cannot be accurately aligned, misalignment and eccentricity are likely to occur, resulting in uneven force at the welded joints. When bearing loads, stress concentration is likely to occur at weak points, reducing the overall bearing capacity of the structure. Summary of the invention

A rotating wheel is arranged around the inner side of the feed barrel. When the steel bar enters the feed barrel, the contact friction between the steel bar and the inner wall of the feed barrel is converted into rolling friction, so as to avoid the steel bar contacting and rubbing with the inner wall of the feed barrel for a long time, which will cause wear on the feed barrel and the surface of the steel bar. At the same time, when the steel bar passes through the feed barrel, the position of the steel bar can be located. When the steel bar continues to move in the feed barrel, the side of the steel bar can be cleaned through the contact mechanism; The contact mechanism comprises a contact shell, one side of the contact shell is rotatably connected to the rotating component, the other side of the contact shell is fixedly connected to the feed barrel, the inner wall of the contact shell is slidably connected to a contact rod, one end of the contact rod away from the inner wall of the contact shell is fixedly connected to a contact plate, the number of the contact plates is four, the four contact plates are evenly arranged on the inner side of the contact shell, a first spring is sleeved on the contact rod, one end of the first spring is fixedly connected to the contact plate, and the other end of the first spring is fixedly connected to the inner wall of the contact shell; When the steel bar enters the feed barrel through the rotating wheel, the steel bar is pushed to move continuously, so that the side of the steel bar contacts and moves with the side of the contact plate, so that the contact plate can clean the side of the steel bar. By surrounding the contact plate and the contact rod on the inner side of the contact shell, when the contact plate cleans the steel bar, when the extrusion force between the contact plate and the steel bar is greater than the tensile force of the first spring, the contact plate moves toward the inner side of the contact shell through the contact rod, and at the same time, the buffering extrusion of the first spring is used to avoid excessive extrusion force between the contact plate and the steel bar support, thereby causing extrusion damage to the contact plate and the side of the steel bar.

When the transmission gear rotates, the transmission gear also drives the driven gear to rotate, so that the driven gear drives the main body to rotate. When the main body rotates, it also drives the welding components installed on the main body to rotate synchronously. The welding components continue to weld the steel bars during the rotation process to ensure that the welding parts of the steel bars are evenly heated to achieve high-quality rotational welding. At the same time, the collection component is turned on to collect the waste chips generated during welding.

[0005] Preferably, the collecting component includes a collecting shell, the collecting shell is arranged on both sides of the middle part of the main body, the side of the collecting shell is fixedly connected to the inner side of the main body, the side of the collecting shell is fixedly connected to the welding component, the side of the collecting shell away from the main body is fixedly connected to an air suction machine, the side of the collecting shell away from the air suction machine is fixedly connected to a baffle, the inner side of the collecting shell is fixedly connected to a magnet mesh plate, and the side of the baffle close to the magnet mesh plate is fixedly connected to a connecting mechanism; When welding is performed, the main body rotates to drive the welding parts to rotate. By turning on the suction machine, the suction force generated by the suction machine drives the connection mechanism to move toward the magnet mesh plate, so that the connection mechanism is separated from the mesh of the baffle plate, so that when the steel bar is welded, the debris generated can enter the collection shell through the baffle plate, and at the same time, the waste debris generated during welding can be adsorbed and processed through the magnet mesh plate; Preferably, the connecting mechanism comprises a connecting plate, the side surface of the connecting plate is slidably connected to the inner side of the collecting shell, a telescopic rod is fixedly connected to the side of the connecting plate close to the baffle, the number of the telescopic rods is four, the four telescopic rods are arranged around the connecting plate, the other end of the telescopic rod is fixedly connected to the side surface of the baffle, a second spring is sleeved on the telescopic rod, one end of the second spring is fixedly connected to the connecting plate, the other end of the second spring is fixedly connected to the baffle, and a moving component is evenly arranged on the side of the connecting plate close to the baffle, and the moving component is concentrically arranged with the mesh of the baffle; When welding, the suction force of the vacuum machine is used to move the connecting plate toward the magnet mesh plate, and the connecting plate drives the moving assembly to separate from the mesh of the baffle plate by pulling the telescopic rod and the second spring, thereby avoiding interference with welding waste chips entering the collection shell; When the welding work is finished, the suction machine is turned off and the suction work is stopped, so that the connecting plate is driven by the stretching and resetting of the second spring, so that the connecting plate drives the moving assembly to move toward the mesh of the baffle plate, thereby blocking the mesh of the baffle plate to prevent impurities entering the collection shell from falling; Preferably, the moving assembly includes a moving rod, one end of the moving rod away from the baffle is fixedly connected to the connecting plate, a clearance groove is opened on the side of the moving rod, one end of the moving rod close to the baffle is fixedly connected to a moving block, a sliding rod is slidably connected to the inner side of the clearance groove, and one end of the sliding rod away from the inner side of the clearance groove is fixedly connected to a scraper, the number of the scrapers is two, the two scrapers are symmetrically arranged with the moving rod as the center, both sides of the scraper are in contact with the inner side of the clearance groove, a third spring is sleeved on the sliding rod, one end of the third spring is fixedly connected to the inner side of the clearance groove, and the other end of the third spring is fixedly connected to the scraper; When the suction machine stops working, the connecting plate is driven by the reset of the second spring to drive the moving rod to move toward the mesh of the baffle, so that the moving rod drives the moving block to eject the impurities blocked in the baffle, thereby avoiding the impurities entering the collection shell through the baffle when collecting the debris generated during welding and clogging the mesh of the baffle, thereby causing the baffle mesh to be blocked; At the same time, when the moving rod continues to move at the baffle mesh, the moving rod can drive the scrapers on both sides to contact and move with the inner wall of the baffle mesh, so that the scrapers can clean the inner wall of the baffle mesh. When the moving rod drives the scrapers on both sides to clean the inner wall of the baffle mesh; When the squeezing force between the scraper and the inner wall of the baffle mesh is greater than the tensile force of the third spring, the third spring is squeezed and stretched, and the third spring drives the scraper to move toward the give way groove, thereby avoiding excessive squeezing force between the scraper and the inner wall of the baffle mesh, which will cause scratches and damage to the inner wall of the baffle mesh; At the same time, when the connecting plate is continuously pulled and reset by the second spring, the connecting plate drives the moving rod to block the mesh of the baffle, thereby preventing impurities entering the collection shell from falling.

[0006] The present invention provides a steel bar connection device for road and bridge construction that is easy to locate and has the following beneficial effects: 1. This steel bar connection equipment for road and bridge construction, which is easy to position, is provided with a feeding component. The rotating wheels arranged around the inner side of the feed barrel make multiple contacts with the surface of the steel bars after the steel bars enter the feed barrel. These rotating wheels are evenly distributed, and they not only convert sliding friction into rolling friction, but also play a role in auxiliary positioning. Since the position of the rotating wheels is relatively fixed, the steel bars are supported and guided by multiple rotating wheels during movement, which further limits their position deviation in the feed barrel. For example, when the steel bars are moving forward, if there is a slight radial deviation, the rotating wheels will push them back to the relative center position through the contact force, so as to always keep the steel bars moving smoothly along the axis direction of the feed barrel, thereby achieving precise positioning.

[0007] 2. The steel bar connection equipment for road and bridge construction, which is easy to position, is provided with a contact mechanism. When the steel bar enters the feed barrel through the rotating wheel and moves continuously, its side contacts and moves relatively with the contact plate. The contact plate can clean the side of the steel bar and remove dust, rust and other impurities on the surface of the steel bar, which is beneficial to ensure the quality of the connection between the steel bar and other components, as well as the bonding effect between the steel bar and the concrete, thereby improving the overall performance of the road and bridge structure.

[0008] 3. This steel bar connection equipment for road and bridge construction, which is easy to locate, is equipped with a magnetic mesh plate, which can effectively separate magnetic metal debris by adsorbing welding waste through the magnetic mesh plate, thus improving the pertinence and effect of collection. This helps to classify and recycle the collected debris in the future, and at the same time prevents the magnetic debris from moving randomly in the collection shell or re-entering the working area, further improving the cleanliness and safety of the working environment.

[0009] 4. The steel bar connection equipment for road and bridge construction, which is easy to position, is provided with a moving component. When the moving rod moves continuously, it drives the scrapers on both sides to contact the inner wall of the baffle mesh, so as to clean the inner wall, further prevent impurities from accumulating inside the mesh, maintain the normal ventilation and collection function of the mesh, reduce the frequency of manual cleaning due to mesh blockage, and improve work efficiency.
