Description

Technical Field

[0001] This utility model relates to the field of spiral steel pipe manufacturing technology, and in particular to a finished product unloading device for a spiral steel pipe production line. Background Technology

[0002] The production process of spiral welded steel pipes is as follows: strip steel uncoiling, leveling, edge trimming, edge planing, surface cleaning, and pre-bending. Then, the steel plate formed from the strip steel is placed on a conveyor belt, which feeds it into a forming machine. In the forming machine, the steel plate is gradually rolled up by multiple rollers at room temperature, forming a circular pipe blank with an opening gap. After welding the gaps on the pipe blank, the finished spiral welded steel pipe is produced. Figure 5 As shown, the spiral welded steel pipe production line is divided into two parts: the front axle (5) and the rear axle (6). The front axle includes functions such as uncoiling, leveling, edge trimming, edge planing, surface cleaning, pre-bending, feeding, and storage. The rear axle includes internal and external welding and length-cutting devices. Because the forming angle must be kept stable throughout the spiral welded steel pipe production process, the front axle (5) and rear axle (6) of the spiral welded steel pipe production equipment must be arranged at a certain angle. This angle is the forming angle. Due to the relatively long total length of the front axle equipment, to improve plant utilization, the front axle is generally arranged along the length of the plant. In this case, the rear axle is inclined at a certain angle to the length of the plant. In existing technology, after the spiral welded steel pipe is cut to length by the rear axle, it is hoisted and unloaded by a crane in the workshop. The finished spiral welded steel pipe is large and heavy, making the hoisting operation dangerous and inefficient. Therefore, the industry urgently needs a finished product unloading device for spiral welded steel pipe production lines. Utility Model Content

[0003] The purpose of this utility model is to provide a finished product unloading device for a spiral steel pipe production line, which adapts to the layout of the production workshop during the manufacturing process of spiral steel pipes and allows for the turning and transportation of large-sized spiral steel pipes within the workshop.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: A finished product unloading device for a spiral steel pipe production line includes a roller conveyor mechanism, a steering and transfer mechanism, an arc track, and a steel pipe receiving car. The roller conveyor mechanism, the steering and transfer mechanism, the arc track, and the steel pipe receiving car are all installed on the ground in the workshop. The roller conveyor mechanism accelerates the conveying of spiral steel pipes cut to length on the front axle. After receiving the spiral steel pipes, the steering and transfer mechanism runs along the arc track and then unloads the spiral steel pipes onto the steel pipe receiving car.

[0005] The finished product unloading device of the spiral steel pipe production line mentioned above, the roller conveyor mechanism includes a roller base and a rotating roller assembly. The rotating roller assembly is provided in five sets, all of which are installed on the roller base. The rotating roller assembly includes a rotating roller base and rotating rollers. Two rotating rollers are installed on the rotating roller base, one of which is an active rotating roller driven by a motor, and the other is a driven rotating roller.

[0006] The finished product unloading device of the aforementioned spiral steel pipe production line includes a steering and transfer mechanism comprising a left lifting arm, a right lifting arm, a hinged seat, a left hydraulic cylinder, a right hydraulic cylinder, a base plate, a drive wheel, a driven wheel, and a guide assembly. The hinged seat is mounted on the base plate. One end of both the left and right lifting arms is hinged to the hinged seat. There are two left and two right hydraulic cylinders, the lower ends of which are hinged to the base plate via supports, and the upper ends are hinged to the left and right lifting arms, respectively. Drive wheels and driven wheels are located at the four corners of the base plate. The drive wheels are driven by a motor, which drives the steering and transfer mechanism to run along the track.

[0007] The above-mentioned spiral steel pipe production line finished product unloading device has four sets of guide components, which are respectively installed at the four corners of the base plate. Each set includes a guide wheel and a guide wheel support. One guide wheel is set on each side of the arc track. The guide wheel is installed on the guide wheel support, and the guide wheel support is installed on the base plate.

[0008] This utility model has the following advantages: In this invention, after the spiral steel pipe is cut to length on the front axle, it is rapidly conveyed by a roller conveyor mechanism to quickly detach from the front axle, preparing for timely transfer. Then, the left lifting arm of the steering and transfer mechanism lifts the spiral steel pipe, and the steering and transfer mechanism carries the spiral steel pipe for transfer at a changing angle. Finally, after the length direction of the spiral steel pipe is perpendicular to the length direction of the production workshop, it is dropped into the steel pipe receiving car. This invention's steering and transfer transportation of spiral steel pipes facilitates the overall layout of the production workshop. Under the control of the control center, automated production can be achieved, improving production efficiency while reducing the dangers of the original manual hoisting operations.

The roller conveyor mechanism 1 is equipped with 5 sets of roller assemblies. The roller base 1-2 in each roller assembly is fixedly installed on the roller base 1-1. Two rollers 1-3 are installed on the roller base 1-2. One roller is the active roller, driven by a motor, and the other is the driven roller. The active roller drives the spiral steel pipe 7 to rotate and accelerate away from the front axle 6 and reach the designated position.

[0012] This utility model discloses a finished product unloading device for a spiral steel pipe production line. In the steering and transfer mechanism 2, a hinged seat 2-3 is set on the base plate 2-6. One end of the left lifting arm 2-1 and the right lifting arm 2-2 are both hinged to the hinged seat 2-3. Two left hydraulic cylinders 2-4 and two right hydraulic cylinders 2-5 are provided. The lower ends of the cylinders are hinged to the base plate 2-6 through supports, and the upper ends are hinged to the left lifting arm 2-1 and the right lifting arm 2-2, respectively. Drive wheels 2-7 are provided on the base plate 2-6 near the two corners of the roller conveyor mechanism 1, and driven wheels 2-8 are provided below the other two corners. The drive wheels 2-7 are driven by a motor, which drives the steering and transfer mechanism 2 to reciprocate along the arc track 3.

[0013] This utility model relates to a finished product unloading device for a spiral steel pipe production line, such as... Figure 4As shown, the guide assembly 2-9 includes a guide wheel 2-9-1 and a guide wheel support 2-9-2. One guide wheel 2-9-1 is set on each side of the arc track 3. The guide wheel 2-9-1 is mounted on the guide wheel support 2-9-2. The guide wheel support 2-9-2 is mounted on the base plate 2-6. The guide assembly 2-9 has four sets, which are respectively installed at the four corners of the base plate 2-6.

[0014] This utility model discloses a finished product unloading device for a spiral steel pipe production line. The working principle is as follows: After the spiral steel pipe 7 is welded and cut to length on the front axle 6, it is driven by the rotating roller 1-3 to accelerate its movement on the roller conveyor mechanism 1. Upon reaching the designated position, a photoelectric sensor sends a signal to the control center. The control center then sends a signal, stopping the rotating roller 1-3. At this time, the left lifting arm 2-1 is leveled, with its two ends positioned between two adjacent rotating roller assemblies. Subsequently, the two left hydraulic cylinders 2-4 synchronously push the left lifting arm 2-1, causing the spiral steel pipe 7 to roll down under gravity onto the conveyor belt between the left and right lifting arms 2-1. At the bottom of the V-shape formed by the lifting arm 2-2, the motors of the two drive wheels 2-7 start working, driving the steering and transfer mechanism 2 to move along the arc-shaped track 3. After reaching the designated position, the control center receives the position signal from the sensor and instructs the drive wheels 2-7 to stop working. Then, the two right hydraulic cylinders 2-5 work, and the right lifting arm 2-2 gradually lowers. Under the action of gravity, the spiral steel pipe 7 slowly rolls onto the steel pipe receiving cart 4. Due to the spatial layout requirements of the multi-process workshop, the steel pipe receiving cart 4 is aligned with the width direction of the workshop building. Finally, the spiral steel pipe 7 is transferred by the steel pipe receiving cart 4 to the next process. After the unloading is completed, the steering and transfer mechanism 2 retracts, preparing for the next operation, and so on. The movement or operation of the components in this utility model is controlled by the control center, which can realize automated production.
