Technical Field

[0002] The first choice for loading the front section of the auxiliary machine of the necking machine is that workers lift the whole bundle of steel pipes and place them on the loading rack platform, and then manually spread the pipes, line them up and lay them flat on the rack platform, and finally use the material hook to turn the steel pipes one by one to the roller of the next process. The whole bundle of steel pipes is lifted and placed on the loading rack platform, which causes the steel pipes to pile up.

[0021] In the scheme of this application:

[0022] 1. In order to solve the problem that the existing equipment is cumbersome to operate and difficult to grasp due to the long length of the steel pipe and the slippery pipe wall, and manual assistance is required, which affects the operation effect of the automated production line, the present application cooperates with the lifting mechanism and the feeding mechanism, and the steel pipe is lifted by the lifting mechanism and automatically enters the interior of the feeding mechanism, and then the feeding mechanism is rotated to discharge the material, thereby realizing automatic feeding, reducing the operation steps of the equipment, thereby reducing the labor intensity of the workers and improving the work efficiency;

[0041] In order to enable those skilled in the art to better understand the scheme of the present invention, the technical scheme in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the present invention.

[0042] As described in the background technology, due to the long length of the steel pipe and the slippery pipe wall, the existing equipment is cumbersome to operate and difficult to grasp, and manual assistance is required, which affects the operation effect of the automated production line.

[0043] In order to solve this technical problem, the present invention provides a lifting type loading platform and a bulk material device, which are applied to steel pipe processing and loading.

[0044] Specifically, please refer to Figure 1-10The lifting loading platform specifically includes a lifting mechanism 1, which includes a bracket 101 and a fixed frame 103. The top array of the bracket 101 is provided with a belt 102. The fixed frame 103 is internally rotatably provided with a belt reel 109. The middle part of the fixed frame 103 is fixedly installed with a first motor 105, a second motor 106, a third motor 107 and a fourth motor 108. The top of the fixed frame 103 is rotatably installed with a loading mechanism 2. The belt reel 109 is transmission-connected to the output end of the first motor 105. One end of the belt 102 is fixedly installed on the top of the bracket 101, and the other end is fixedly connected to the surface of the belt reel 109 around the top of the loading mechanism 2. A counterweight 104 is suspended in the middle of the belt 102.

[0045] The feeding mechanism 2 includes a driving shaft 201 and a fixed shaft 202. The driving shaft 201 is rotatably mounted on the top of the fixed frame 103. The driving shaft 201 is transmission-connected to the output end of the second motor 106. A blocking ring 211 is fixedly mounted at equal intervals on the surface of the driving shaft 201. Four blocking hooks 215 are slidably engaged inside the blocking ring 211. An articulated shaft 216 is fixedly mounted on the inner end of the blocking hook 215. Four sliding articulated grooves 214 are formed at equal angles in the middle of the inner cavity of the blocking ring 211. The articulated shaft 216 is articulated inside the sliding articulated groove 214. The inner end of the blocking hook 215 is movably articulated with a pressing plate 217 through a torsion spring.

[0046] The lifting mechanism 1 delivers the steel pipe in the belt 102 into the interior of the feeding mechanism 2, and fixes the steel pipe through the feeding mechanism 2 and then discharges the steel pipe.

[0047] The belt reel 109 is driven to rotate by the first motor 105, thereby lifting and lowering the belt 102. When the belt 102 is lifted to a specified height, the steel pipes stacked on the belt 102 can slide into the interior of the material blocking hook 215 through the pressure plate 217, and then the driving shaft 201 is driven to rotate by the second motor 106, so that the driving shaft 201 pulls the material blocking ring 211 to rotate synchronously and send the steel pipes to the next link.

[0048] The lifting loading platform provided by the present invention is to solve the problem in the prior art that the existing equipment is cumbersome to operate and difficult to grasp due to the long length of the steel pipe and the slippery pipe wall, and manual assistance is required, which affects the operation effect of the automated production line. The present application cooperates with the setting of the lifting mechanism 1 and the loading mechanism 2. The steel pipe is lifted by the lifting mechanism 1 and automatically enters the interior of the loading mechanism 2, and then the feeding mechanism 2 is rotated to discharge the material, thereby realizing automatic loading, reducing the operating steps of the equipment, thereby reducing the labor intensity of workers and improving work efficiency.

[0049] In order to enable those skilled in the art to better understand the solutions of the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings.

[0050] It should be noted that, in the absence of conflict, the embodiments of the present invention and the features and technical solutions in the embodiments may be combined with each other.

[0051] It should be noted that similar reference numerals and letters denote similar items in the following drawings, and therefore, once an item is defined in one drawing, further definition and explanation thereof is not required in subsequent drawings.

[0052] Example 1, please refer to Figure 1-10 , a lifting type loading platform and a bulk material device, which comprises a lifting mechanism 1, the lifting mechanism 1 comprises a bracket 101 and a fixed frame 103, a belt 102 is arranged in an array on the top of the bracket 101, a belt reel 109 is arranged for rotation inside the fixed frame 103, a first motor 105, a second motor 106, a third motor 107 and a fourth motor 108 are fixedly installed in the middle of the fixed frame 103, a loading mechanism 2 is rotatably installed on the top of the fixed frame 103, the belt reel 109 is transmission-connected to the output end of the first motor 105, one end of the belt 102 is fixedly installed on the top of the bracket 101, and the other end is fixedly connected to the surface of the belt reel 109 around the top of the loading mechanism 2, and a counterweight 104 is suspended in the middle of the belt 102;

[0053] The feeding mechanism 2 includes a driving shaft 201 and a fixed shaft 202. The driving shaft 201 is rotatably mounted on the top of the fixed frame 103. The driving shaft 201 is transmission-connected to the output end of the second motor 106. A blocking ring 211 is fixedly mounted at equal intervals on the surface of the driving shaft 201. Four blocking hooks 215 are slidably engaged inside the blocking ring 211. An articulated shaft 216 is fixedly mounted on the inner end of the blocking hook 215. Four sliding articulated grooves 214 are formed at equal angles in the middle of the inner cavity of the blocking ring 211. The articulated shaft 216 is articulated inside the sliding articulated groove 214. The inner end of the blocking hook 215 is movably articulated with a pressing plate 217 through a torsion spring.

[0054] The lifting mechanism 1 delivers the steel pipe in the belt 102 into the interior of the feeding mechanism 2, and fixes the steel pipe through the feeding mechanism 2 and then discharges the steel pipe;

[0055] The surface of the driving shaft 201 is sleeved with a fixed shaft 202 at equal intervals. The fixed shaft 202 is fixedly mounted on the top of the fixing frame 103 and located inside the material stop ring 211. An arc-shaped slide groove 203 is provided on the side of the fixed shaft 202. The interior of the arc-shaped slide groove 203 is slidably engaged with a limit block 204 through a spring. The inner end of the pressing plate 217 is located inside the material stop ring 211 and fits on the side of the limit block 204.

[0056] The inner side and the back side of the blocking ring 211 are respectively provided with a receiving groove 212 and a docking groove 213. A guide rod 206 is sleeved on the middle part of the driving shaft 201. A fixing ring 207 is fixedly installed on the surface of the guide rod 206 at equal intervals. Four positioning blocks 208 are fixedly installed at equal angles on the circumferential side of the fixing ring 207. Four card slots 205 are provided on the surface of the driving shaft 201 in an evenly spaced circumferential array. The fixing ring 207 is slidably engaged in the card slot 205.

[0057] One end of the guide rod 206 is fixedly connected to a support spring 209, and the outer end of the support spring 209 is provided with an electromagnet rod 210, and the outer end of the electromagnet rod 210 is rotatably mounted on the fixed frame 103, and the four positioning blocks 208 at the inner end of the fixed ring 207 are respectively engaged with the back of the four material blocking hooks 215;

[0058] The docking groove 213 is used to dock with the pressure plate 217, and the receiving groove 212 is used to receive the blocking hook 215. The outer end of the pressure plate 217 is attached to the outer end of the blocking hook 215 to engage and limit the steel pipe. The feeding mechanism 2 rotates clockwise, and under the influence of gravity, when the pressure plate 217 and the blocking hook 215 move to the upper left side, the pressure plate 217 is attached to the inside of the docking groove 213. When the steel pipe is transported, when the positioning block 208 limited on the back of the blocking hook 215 is removed, the blocking hook 215 will automatically sink under the action of gravity and the hinged end of the blocking hook 215 and the pressure plate 217 will rotate outward, and at the same time, the blocking hook 215 will rotate into the inside of the receiving groove 212, so that the steel pipe falls to the top of the first chain 301.

[0059] The belt reel 109 is driven to rotate by the first motor 105, thereby lifting and lowering the belt 102. When the belt 102 is lifted to a specified height, the steel pipe is slightly higher than the top of the pressing plate 217, so that the steel pipe stacked on the belt 102 can slide into the interior of the blocking hook 215 through the pressing plate 217, and then the driving shaft 201 is driven to rotate by the second motor 106, so that the driving shaft 201 pulls the blocking ring 211 to rotate synchronously and send the steel pipe to the next link. In the process of the blocking hook 215 transporting the steel pipe, the pressing plate is pressed by the limit block 204. The inner end of 217 is limited, and the back side of the blocking hook 215 is limited by the positioning block 208. When the blocking ring 211 rotates synchronously with the pressure plate 217, the outer end of the pressure plate 217 will approach the blocking hook 215 and squeeze the steel pipe on the surface of the pressure plate 217 toward the surface of the blocking hook 215. At this time, the limit block 204 rotates to the rightmost end and stops rotating due to the restriction of the arc slide groove 203, so that the inner end of the pressure plate 217 is further squeezed, and the blocking ring 211 continues to rotate, so that multiple points of the steel pipe continue to be squeezed, so that the steel pipe is pressed straight.

[0060] In order to solve the problem in the prior art that some steel pipes are slightly bent during processing and need to be straightened through secondary processing later, the present application sets up a feeding mechanism 2. When discharging materials, the feeding mechanism 2 moves the steel pipe to the top of the bulk material mechanism 3 before putting it down. The blocking hook 215 is limited by the positioning block 208, and then the inner end of the pressing plate 217 is squeezed by the limiting block 204 so that the fixing ring 207 can continue to move inward. The bent steel pipe is straightened by the feeding mechanism 2 set up in an array, which not only achieves the discharge of the steel pipe, but also can be straightened by the action coordination of the feeding mechanism 2 before discharging.

[0061] Embodiment 2 further optimizes the lifting loading platform provided in embodiment 1. Specifically, Fig.10 As shown, when the feeding mechanism 2 rotates to make the blocking hook 215 flush with the first chain 301, the electromagnetic iron rod 210 is powered off and demagnetized. The guide rod 206 will move outward with the fixing ring 207 and the positioning block 208 under the elastic support of the supporting spring 209, so that the back of the blocking hook 215 loses support. At this time, the blocking hook 215 loses support, and its inner end will rotate outward, so that the inner end of the blocking hook 215 will rotate outward with the pressing plate 217 at the same time. At this time, the pressing plate 217 will make the limit block 204 lose its restriction, and the limit block 204 is reset under the action of the spring. After the pressing plate 217 rotates outward, and under the action of the torsion spring, its top rotates upward, so that the pressing plate 217 is inclined with the steel pipe. At this time, the blocking ring 211 continues to be rotated so that the pressing plate 217 pushes the steel pipe outward on the surface of the first chain 301, and the blocking ring 211 continues to prepare for the discharge of the next batch of steel pipes.

[0062] The feeding mechanism 2 is set up so that the steel pipe can be placed stably on the surface of the first chain 301, and then the steel pipe is sent away by the first chain 301, thereby achieving the stable placement of the steel pipe and preventing the steel pipe from sliding forward during the placing process, causing local tilting of the steel pipe. This solves the problem in the prior art that the steel pipe is tilted due to local sliding during the placing process, thereby affecting the later transportation and processing of the steel pipe.

[0063] Further, such as Figure 1-3As shown, it also includes a supporting mechanism 4, which is arranged on the right side of the bulk material mechanism 3. The supporting mechanism 4 includes an electric cylinder 401, which is fixedly installed on the bottom outer side of the fixing frame 103. The output end of the electric cylinder 401 is fixedly connected to a traction rod 402. The outer side of the fixing frame 103 is vertically slidably connected with a connecting plate 403. The top array of the connecting plate 403 is provided with a supporting plate 404, and the supporting plate 404 is located on the side of the second chain 302. Four top rods 406 are fixedly installed at an equal distance on the top of the traction rod 402. The top of the top rod 406 is inclined and fits the bottom of the protrusion on the bottom surface of the connecting plate 403. When the traction rod 402 is extended, the connecting plate 403 is pulled by squeezing the protrusion. The pallet 404 moves upward, and the top of the pallet 404 is inclined downward in a two-step manner. The sides of the second support plate 111 are slidably clamped with blocking blocks 405, and the blocking blocks 405 are located on the sides of the pallet 404. The electric cylinder 401 controls the movement of the traction rod 402, and then the top rod 406 pulls the connecting plate 403 up and down, thereby controlling the lifting and lowering of the pallet 404, and then the steel pipes on the top of the second chain 302 are sent one by one to the next link. The two-step design of the pallet 404 can be used to send the steel pipes to the outside of the pallet 404. By adjusting the distance between the blocking block 405 and the outermost side of the second chain 302, it is suitable for limiting the steel pipes with different outer diameters.

[0064] Example 3, please refer to Figure 1-3 The top of the fixed frame 103 is located on the right side of the feeding mechanism 2 and a bulk material mechanism 3 is provided. The bulk material mechanism 3 includes a first chain 301 and a second chain 302. The top of the fixed frame 103 is equidistantly fixed with a first support plate 110 and a second support plate 111. The first chain 301 is rotatably installed on the top of the first support plate 110, and the second chain 302 is rotatably installed on the top of the second support plate 111. The first chain 301 and the second chain 302 partially overlap and have the same rotation direction. An infrared detection device 303 is provided on the side of the first chain 301. The first chain 301 and the second chain 302 are respectively connected to the third motor 107 and the fourth motor 108 for transmission. The third motor 107 and the fourth motor 108 respectively control the rotation of the first chain 301 and the second chain 302, so that the steel pipe moves on the top of the bulk material mechanism 3, and the infrared detection device 303 is used to perform infrared detection on the top of the first chain 301.

[0065] By setting up a dispersing mechanism 3, the steel pipes are dispersed and transported by using the first chain 301 and the second chain 302, and the steel pipes are detected by the infrared detection device 303. When it is detected that the steel pipes are stacked, the first chain 301 is rotated in the opposite direction, and then the steel pipes are dispersed by shaking, thereby realizing the transportation of the steel pipes and dispersing the stacked steel pipes by rotating in the opposite direction when stacking occurs.

[0066] The use process of the lifting loading platform and bulk material device provided by the present invention is as follows:

[0067] The steel pipe is first placed on the top of the belt 102, and then the belt 102 is controlled by the first motor 105 to lift the steel pipe, and is sent into the interior of the blocking hook 215 along the pressure plate 217. At this time, the second motor 106 controls the blocking ring 211 to rotate. Since the positioning block 208 limits the back of the blocking hook 215 and cooperates with the limiting block 204 to squeeze the inner end of the pressure plate 217, the outer end of the pressure plate 217 will approach the blocking hook 215 and squeeze the steel pipe to the blocking hook 215 to initially fix the steel pipe to prevent shaking and displacement during the movement of the steel pipe. When the material stopper 215 is above the material mechanism 3, the limit block 204 is stuck in the rightmost side of the arc-shaped slide groove 203, and the stopper ring 211 continues to rotate, so that the limit block 204 further squeezes the inner end of the pressure plate 217, so that the pressure plate 217 exerts strong pressure on the surface of the steel pipe, so that the steel pipe is pressed straight. When the electromagnetic iron rod 210 is powered off, the control guide rod 206 moves outward under the action of the support spring 209, and the positioning block 208 is separated from the back of the stopper hook 215. At this time, the stopper hook 215 loses its support, and the end of its inner end hinged to the pressure plate will rotate outward, so that the stopper hook 215 The inner end rotates outward with the pressing plate 217 at the same time. At this time, the pressing plate 217 will make the limit block 204 lose its restriction. The limit block 204 is reset under the action of the spring. After the pressing plate 217 rotates outward, under the action of the torsion spring, its top rotates upward to fit into the inside of the docking groove 213, so that the pressing plate 217 and the steel pipe are tilted. The surface of the steel pipe on the blocking hook 215 will fall into the receiving groove 212 inside the blocking ring 211 synchronously with the blocking hook 215, and the steel pipe will fall smoothly onto the surface of the first chain 301. At this time, the blocking ring 211 continues to rotate to make the pressing plate 217 The steel pipe is pushed outward on the surface of the first chain 301. When the steel pipe completely falls on the surface of the first chain 301, the steel pipe is moved to the second chain 302 through the first chain 301, and the infrared detection device 303 is used to detect whether there is stacking on the first chain 301. When stacking occurs, the first chain 301 is rotated in the opposite direction for a short distance to disperse the stacked steel pipes on the first chain 301, and then the steel pipe is sent to the supporting mechanism 4 through the second chain 302, and the lifting of the support plate 404 is controlled by the electric cylinder 401, and the stop block 405 is used to send the steel pipes one by one to the next link.
