Description

Technical Field

[0001] The utility model relates to a steel pipe rust removal device, in particular to a feeding mechanism of the steel pipe surface rust removal device. Background Art

[0002] Seamless steel pipe is a kind of pipe mainly used for transporting fluids and gases, with good air tightness and excellent mechanical properties. However, like other steel materials, seamless steel pipe is prone to rust, so it is necessary to spray anti-rust paint on its outer surface. Before the painting process, the surface of the steel pipe needs to be rust-free.

[0003] Existing steel pipe rust removal devices generally include a conveying assembly for conveying steel pipes and a rust removal assembly, wherein the conveying assembly is generally composed of a number of guide rollers, and the guide rollers are generally distributed in a V-shape. The steel pipe is placed flat on the conveying assembly, and the guide rollers rotate to drive the steel pipe to move toward the rust removal assembly. By adjusting the angle of the guide rollers, it is also possible to achieve the effect of driving the steel pipe forward while driving it to rotate.

[0004] During the storage and transportation process, steel pipes are generally stacked in bundles. Therefore, during the steel pipe rust removal process, workers need to place the steel pipes one by one at the feeding port of the conveying component of the rust removal equipment. This requires workers to frequently load the steel pipes, which not only consumes workers' physical strength and time, but also increases the company's demand for the number of workers. Therefore, seamless steel pipe manufacturers are in urgent need of a steel pipe loading device that can adapt to existing rust removal devices and can load materials independently. Summary of the invention

[0005] The utility model provides a feeding mechanism for a steel pipe surface rust removal device, which solves the problem in the prior art that workers are required to feed the steel pipe rust removal device.

[0006] The above technical problems of the utility model are mainly solved by the following technical solutions: a feeding mechanism of a steel pipe surface rust removal device, comprising a frame, a steel pipe stacking groove located on the frame, a plurality of fixed tooth plates fixedly arranged on the frame, a plurality of movable tooth plates that can reciprocate up and down, and a guide plate arranged on the upper side of the frame, the number of fixed tooth plates is at least two and they are all arranged at the same height, the number of movable tooth plates is at least two and they are all arranged at the same height, the frame is also provided with a driving device for driving the movable tooth plate to move, the fixed tooth plate is provided with a plurality of first clamping teeth along an inclined linear array, the movable tooth plate is provided with a second clamping tooth arranged in an array in the same manner as the first clamping teeth, the sizes of the two clamping teeth are adapted to the steel pipe, each clamping tooth can only clamp one steel pipe at most, the first clamping tooth and the second clamping tooth are staggered in the vertical direction, the movement amplitude of the movable tooth plate is greater than or equal to the height difference between the tooth top and tooth bottom of the first clamping tooth, the guide plate is inclined, and its high side is connected to the topmost first clamping tooth, and the distribution path of the first clamping tooth and the second clamping tooth is to extend into the steel pipe stacking groove.

[0007] When the movable tooth plate moves to the lowest position, the steel pipe in the steel pipe stacking trough will roll down to the second clamping tooth at the bottom again under the action of gravity, and then the movable tooth plate moves upward, and the second clamping tooth will drive the steel pipe to move upward, and when the movable tooth plate moves to the highest point, the steel pipe will roll from the second clamping tooth to the first clamping tooth, so when the movable tooth plate descends, the steel pipe originally located on the movable tooth plate is transferred to the fixed tooth plate, and a lifting is completed. According to this rule, each time the movable tooth plate is lifted and lowered, the steel pipe is lifted once, and the steel pipe in the steel pipe stacking trough will be transported away one by one. After the steel pipe is lifted to the highest point, it will automatically roll down to the guide plate, and the lower end of the guide plate is connected with the conveying component of the existing steel pipe rust removal device, so that the steel pipe can automatically roll down to the conveying component.

[0008] Furthermore, the frame is provided with a feed slope connected to the steel pipe stacking trough, a pressure rod is fixedly provided on the upper side of the feed slope, and a feed chute with equal spacing is formed between the pressure rod and the feed slope, and a loading port is also provided at the upper end of the feed chute. After adopting the above technical solution, a forklift or gantry crane is required to place several steel pipes at the loading port at one time. The steel pipes will slide into the steel pipe stacking trough along the feed chute due to gravity. When the stacking height of the steel pipes in the steel pipe stacking trough reaches or nearly reaches the lower end of the pressure rod, the steel pipes in the steel pipe stacking trough cannot continue to increase, so the steel pipes will eventually fill the feed chute and part of the loading port. This arrangement allows the utility model to store more steel pipes, so that after a single addition of steel pipes, there is no need to continue adding for a long time.

[0009] Furthermore, two groups of baffle assemblies distributed front and back are provided in the lower area of ​​the guide plate, and the baffle assembly includes a cylinder fixed on the guide plate and a baffle connected to the telescopic rod of the cylinder, and the spacing between the two baffles is the same as the diameter of the steel pipe; the inclination of the guide plate is between 5 and 20 degrees, and a sensor is also provided on the guide plate. The steel pipe is transported by the coordinated movement of the movable tooth plate and the fixed tooth plate. The reliability of the clamping teeth at the bottom is low, and there is a high probability that the steel pipe cannot be successfully hooked. For this reason, through the above technical scheme, the lifting frequency of the movable tooth plate can be increased, and then the lifted steel pipe will be temporarily arranged on the guide plate. The baffles on the two baffle assemblies are alternately lifted and lowered. After each alternation, a steel pipe can be discharged. At the same time, the sensor is used to detect the number of steel pipes on the guide plate. When the maximum number of steel pipes is reached, the drive device stops working. When it is detected that there are not many remaining steel pipes, the drive device starts again, thereby ensuring the reliability of the feeding of the utility model.

[0010] Therefore, compared with the prior art, the utility model has the following characteristics: 1. The steel pipes are transported by cooperating with the movable tooth plate and the fixed tooth plate which move back and forth, so that the steel pipes can be transported upward one by one, and the steel pipes are guided to the loading position of the rust removal equipment through the guide plate; 2. Two groups of baffle assemblies distributed front and back are provided in the lower area of ​​the guide plate, and the baffles on the two baffle assemblies are raised and lowered alternately, and a steel pipe can be discharged after each alternation.

[0018] When the movable tooth plate moves to the lowest position, the steel pipe in the steel pipe stacking trough will roll back to the second clamping tooth at the bottom under the action of gravity, and then the movable tooth plate moves upward, and the second clamping tooth will drive the steel pipe to move upward. When the movable tooth plate moves to the highest point, the steel pipe will roll from the second clamping tooth to the first clamping tooth. Therefore, when the movable tooth plate descends, the steel pipe originally located on the movable tooth plate is transferred to the fixed tooth plate, and a lifting is completed. According to this rule, each time the movable tooth plate is lifted and lowered, the steel pipe is lifted once, and the steel pipe in the steel pipe stacking trough will be transported away one by one. After the steel pipe is lifted to the highest point, it will automatically roll to the guide plate. The lower end of the guide plate is connected to the conveying component of the existing steel pipe rust removal device, so that the steel pipe can automatically roll onto the conveying component.

[0019] See Figure 4The driving device includes a motor arranged at the bottom of the frame, a crankshaft 620 horizontally mounted on the frame, a horizontal shaft 630 arranged at the bottom of the movable tooth plate, and a connecting rod 640 hinged between the horizontal shaft and the crankshaft.

After adopting the above technical solution, a forklift or a gantry crane is required to place several steel pipes at the loading port at one time. The steel pipes will slide into the steel pipe stacking trough along the feeding chute due to gravity. When the stacking height of the steel pipes in the steel pipe stacking trough reaches or nearly reaches the lower end of the pressure rod, the steel pipes in the steel pipe stacking trough cannot continue to increase, so the steel pipes will eventually fill the feeding chute and part of the loading port. This arrangement allows the present embodiment to store more steel pipes, so that after a single addition of steel pipes, there is no need to continue adding for a long time.

[0022] See Figure 2 , two groups of baffle assemblies 700 distributed front and back are arranged in the lower area of ​​the guide plate, the baffle assembly includes a cylinder 710 fixed on the guide plate and a baffle 720 connected to the telescopic rod of the cylinder, and the spacing between the two baffles is the same as the diameter of the steel pipe; the inclination of the guide plate is between 5 and 20 degrees, preferably between 8 and 15 degrees, and two proximity sensors 800 are also arranged on the guide plate, which are respectively located in the middle and high positions of the guide plate. The steel pipe is transported by the coordinated movement of the movable tooth plate and the fixed tooth plate. The reliability of the clamping teeth at the bottom is low, and there is a high probability that the steel pipe cannot be successfully hooked. For this reason, through the above technical solution, the lifting frequency of the movable tooth plate can be increased, and then the lifted steel pipe will be temporarily arranged on the guide plate. The baffles on the two baffle assemblies are alternately lifted and lowered. After each alternation, a steel pipe can be discharged. At the same time, the sensor is used to detect the number of steel pipes on the guide plate. When the maximum number of steel pipes is reached, the driving device stops working. When it is detected that there are not many steel pipes left, the driving device starts again, thereby ensuring the reliability of the feeding of this embodiment.
