Description

Technical Field

[0001] This utility model relates to a steel pipe stacking and unloading device. Background Technology

[0002] Currently, after steel pipes are processed, they need to be stacked and unloaded. The conventional method is to use a loading plate to lift the steel pipes and flip them over to unload them into a receiving basket. For example, Chinese patent CN203006458U discloses a steel pipe eddy current flaw detection unloading mechanism, which uses a loading plate to lift the steel pipes and flip them over to unload them. However, when the steel pipes are flipped over to unload them using the loading plate, they slide down the loading plate into the receiving basket. When the steel pipes fall into the receiving basket, the impact causes significant noise pollution, and in severe cases, the steel pipes may be damaged by the impact. Utility Model Content

[0066] To make the contents of this utility model easier to understand, the present utility model will be further described in detail below with reference to specific embodiments and accompanying drawings.

[0067] like Figures 1-5 As shown, a steel pipe stacking and unloading device includes a frame 1, a moving crossbeam 2, a moving drive mechanism 3, a lifting drive mechanism 4, at least one lifting seat 5, and an electromagnetic adsorption device 6 corresponding to the lifting seat 5.

[0068] The movable crossbeam 2 is mounted on the frame 1 in a forward and backward direction;

[0069] The moving drive mechanism 3 is connected to the moving crossbeam 2 and is used to drive the moving crossbeam 2 to move back and forth on the frame 1;

[0070] The lifting seat 5 is slidably connected to the moving crossbeam 2 in the vertical direction;

[0071] The lifting drive mechanism 4 is connected to the movable crossbeam 2 and connected to the lifting seat 5, and is used to drive the lifting seat 5 to move up and down.

[0072] The electromagnetic adsorption device 6 is connected to the lower end of the corresponding lifting seat 5 and is used to attract the steel pipe when powered on and to release the attracted steel pipe when powered off.

[0073] Specifically, during the process of transporting and unloading the steel pipe into the receiving basket, firstly, the lifting drive mechanism 4 drives the lifting seat 5 to rise, and the moving drive mechanism 3 drives the moving crossbeam 2 to move back and forth on the frame 1 to above the unloading position. Then, the lifting drive mechanism 4 drives the lifting seat 5 to descend so that the electromagnetic adsorption device 6 contacts the steel pipe in the unloading position. Then, the electromagnetic adsorption device 6 is energized and attracts the steel pipe in the unloading position. Finally, the lifting drive mechanism 4 drives the lifting seat 5 to rise, thereby driving the electromagnetically attracted steel pipe to rise. The steel pipe held by the magnetic adsorption device 6 is lifted up. Then, the moving drive mechanism 3 drives the moving crossbeam 2 to move back and forth to above the receiving frame. Then, the lifting drive mechanism 4 drives the lifting seat 5 to lower so that the steel pipe held by the electromagnetic adsorption device 6 is placed into the receiving frame. Then, the electromagnetic adsorption device 6 is de-energized to release the steel pipe, so that the steel pipe falls into the receiving frame. This greatly reduces the height difference of the steel pipe falling into the receiving frame, realizes the handling and unloading of the steel pipe, reduces the noise pollution generated during the unloading of the steel pipe, and can also prevent the steel pipe from being damaged during unloading.

[0074] like Figure 1 , 4 As shown, the frame 1 may include a left support frame 7 and a right support frame 8;

[0075] The left end of the movable crossbeam 2 is mounted on the left support frame 7 in a forward and backward direction;

[0076] The right end of the movable crossbeam 2 is mounted on the right support frame 8 in a forward and backward direction.

[0077] like Figure 3 As shown, the left support frame 7 is provided with a left slide rail 9, and at least two left wheels 10 are connected to the left end of the movable crossbeam 2. The left wheels 10 are installed on the left slide rail 9 and are used to travel on the left slide rail 9 in the front-back direction, thereby allowing the left end of the movable crossbeam 2 to be moved and set on the left support frame 7 in the front-back direction.

[0078] The right support frame 8 is provided with a right slide rail, and at least two right wheels are connected to the right end of the movable crossbeam 2. The right wheels are installed on the right slide rail and are used to travel on the right slide rail in the front-back direction, thereby allowing the right end of the movable crossbeam 2 to move and be positioned on the right support frame 8 in the front-back direction.

[0079] like Figure 1 As shown, the moving drive mechanism 3 may include a left rack, a left gear, a left moving motor 11, a right rack, a right gear, and a right moving motor 12;

[0080] The left rack is connected to the left support frame 7;

[0081] The left gear is connected to the left moving motor 11 and meshes with the left rack;

[0082] The left moving motor 11 is connected to the left end of the moving crossbeam 2 and is used to drive the left gear to rotate, thereby driving the left end of the moving crossbeam 2 to move in the front-back direction through the cooperation of the left gear and the left rack.

[0083] The right rack is connected to the right support frame 8;

[0084] The right gear is connected to the right moving motor 12 and meshes with the right rack;

[0085] The right moving motor 12 is connected to the right end of the moving crossbeam 2 and is used to drive the right gear to rotate. In turn, the right gear and the right rack work together to drive the right end of the moving crossbeam 2 to move in the front-back direction, thereby driving the entire moving crossbeam 2 to move back and forth.

[0086] like Figures 1-5 As shown, at least two lifting seats 5 are arranged at intervals along the length of the moving crossbeam 2;

[0087] The electromagnetic adsorption device 6 corresponds one-to-one with the lifting seat 5 and is connected to the lower end of the corresponding lifting seat 5;

[0088] The lifting drive mechanism 4 is connected to each of the lifting seats 5 and is used to drive each of the lifting seats 5 to move up and down synchronously. Specifically, when the steel pipe to be transported and unloaded is long, more than two of the electromagnetic adsorption devices 6 need to be set. In this embodiment, there are three electromagnetic adsorption devices 6 and three lifting seats 5.

[0089] like Figures 1-5 As shown, the lifting drive mechanism 4 may include a lifting motor 13, a drive shaft 14, a lifting rack 15 corresponding to the lifting seat 5, and a lifting gear 16 corresponding to the lifting rack 15.

[0090] The drive shaft 14 is rotatably connected to the moving crossbeam 2;

[0091] The lifting rack 15 is connected to the corresponding lifting seat 5;

[0092] The lifting gear 16 is connected to the drive shaft 14 and meshes with the corresponding lifting rack 15;

[0093] The lifting motor 13 is connected to the moving crossbeam 2 and the drive shaft 14. The lifting motor 13 drives the drive shaft 14 to rotate, which in turn drives the lifting gear 16 to rotate. Through the engagement of the lifting gear 16 and the lifting rack 15, each lifting seat 5 moves up and down synchronously. Specifically, when the moving crossbeam 2 is above the unloading position, the lifting motor 13 drives the drive shaft 14 to rotate, which in turn drives the lifting gear 16 to rotate. Through the engagement of the lifting gear 16 and the lifting rack 15, all the lifting seats 5 descend synchronously, causing the electromagnetic adsorption devices 6 on each lifting seat 5 to descend and contact the steel pipe in the unloading position. Then, all the electromagnetic adsorption devices 6 are energized and attract the steel pipe in the unloading position. The lifting motor 13 then drives the drive shaft 14 to rotate, which in turn drives the lifting gear 16 to rotate. Through the engagement of the lifting gear 16 and the lifting rack 15, all the lifting seats 5 rise synchronously, causing the steel pipe attracted by the electromagnetic adsorption devices 6 to rise upwards. In this embodiment, the lifting motor 13 can be a geared motor, and the drive shaft 14 includes a plurality of shaft segments arranged sequentially along the length direction of the moving crossbeam 2. Adjacent shaft segments can be connected by couplings or flanges.

[0094] like Figure 6 , 7 As shown, the electromagnetic adsorption device 6 may include a fixed base 17, a first buffer base 18, a second buffer base 19, an electromagnet 20, a first buffer elastic element 21, and a second buffer elastic element 22.

[0095] The fixed base 17 is connected to the lower end of the corresponding lifting base 5;

[0096] The first buffer seat 18 and the second buffer seat 19 are slidably connected to the fixed seat 17 in the vertical direction, respectively;

[0097] One end of the electromagnet 20 is connected to the lower end of the first buffer seat 18, and the other end of the electromagnet 20 is connected to the lower end of the second buffer seat 19. The electromagnet 20 is used to attract the steel pipe when energized and to release the attracted steel pipe when de-energized.

[0098] The first buffer elastic element 21 is installed between the fixed base 17 and the first buffer base 18. One end of the first buffer elastic element 21 is connected to the fixed base 17, and the other end of the first buffer elastic element 21 is connected to the first buffer base 18.

[0099] The second buffer elastic element 22 is installed between the fixed seat 17 and the second buffer seat 19. One end of the second buffer elastic element 22 is connected to the fixed seat 17, and the other end of the second buffer elastic element 22 is connected to the second buffer seat 19. Specifically, during the process of the lifting seat 5 being driven to descend and thus causing the electromagnetic adsorption device 6 to descend to contact the steel pipe in the unloading position, the lifting seat 5 firstly descends along with the fixed seat 17, the first buffer seat 18, the second buffer seat 19, and the electromagnet 20. When the electromagnet 20 descends to contact the steel pipe in the unloading position, the electromagnet 20, the first buffer seat 18, and the second buffer seat 19 all stop descending. At this time, the lifting seat 5 continues to descend with the fixed seat 17 for a certain height. At this time, relative sliding occurs between the first buffer seat 18 and the fixed seat 17, and between the second buffer seat 19 and the fixed seat 17 in the vertical direction. This causes the first buffer elastic element 21 and the second buffer elastic element 22 to expand and contract respectively, thereby playing a buffering role and preventing the electromagnet 20 from crushing the steel pipe when it descends.

[0100] like Figure 6 , 7 As shown, the fixed base 17 may include a base body 23, a first mounting shaft 24, and a second mounting shaft 25;

[0103] The second mounting shaft 25 is connected to the other end of the seat 23, and the second buffer seat 19 is slidably connected to the second mounting shaft 25 in the up-down direction.

[0104] like Figure 6 , 7 As shown, the first buffer seat 18 includes a first left upright plate 26, a first right upright plate 27, a first top plate 28, a first bottom plate 29, and a first connecting block 30;

[0108] The first left upright plate 26 is provided with a first waist-shaped hole 31 extending in the vertical direction and slidably connected to one end of the first mounting shaft 24, and the first right upright plate 27 is provided with a second waist-shaped hole 32 extending in the vertical direction and slidably connected to the other end of the first mounting shaft 24; the first waist-shaped hole 31 and the first mounting shaft 24 cooperate to allow the first left upright plate 26 to slide in the vertical direction on the first mounting shaft 24, and the second waist-shaped hole 32 and the first mounting shaft 24 cooperate to allow the first right upright plate 27 to slide in the vertical direction on the first mounting shaft 24, thereby allowing the entire first buffer seat 18 to slide in the vertical direction on the first mounting shaft 24;

[0109] A first limiting member 33 is connected to one end of the first mounting shaft 24 to abut against the left end face of the first left upright plate 26, and a second limiting member is connected to the other end of the first mounting shaft 24 to abut against the right end face of the first right upright plate 27; thereby preventing the first buffer seat 18 from moving axially along the first mounting shaft 24.

[0110] The first buffer elastic element 21 is installed between the seat body 23 and the first top plate 28. The lower end of the first buffer elastic element 21 is connected to the seat body 23, and the upper end of the first buffer elastic element 21 is connected to the first top plate 28.

[0111] The second buffer seat 19 includes a second left upright plate 35, a second right upright plate 36, a second top plate 37, a second bottom plate 38, and a second connecting block 39.

[0112] The upper end of the second left vertical plate 35 is connected to one end of the second top plate 37, and the upper end of the second right vertical plate 36 is connected to the other end of the second top plate 37.

[0113] The lower end of the second left upright plate 35 is connected to one end of the second bottom plate 38, and the lower end of the second right upright plate 36 is connected to the other end of the second bottom plate 38.

[0114] The second connecting block 39 is connected to the lower end of the second base plate 38, and the other end of the electromagnet 20 is connected to the second connecting block 39;

[0115] The second left upright plate 35 is provided with a third oblong hole 40 extending in the vertical direction and slidably connected to one end of the second mounting shaft 25, and the second right upright plate 36 is provided with a fourth oblong hole 41 extending in the vertical direction and slidably connected to the other end of the second mounting shaft 25; the cooperation between the third oblong hole 40 and the second mounting shaft 25 enables the second left upright plate 35 to be slidably connected to the second mounting shaft 25 in the vertical direction, and the cooperation between the fourth oblong hole 41 and the second mounting shaft 25 enables the second right upright plate 36 to be slidably connected to the second mounting shaft 25 in the vertical direction, thereby enabling the entire second buffer seat 19 to be slidably connected to the second mounting shaft 25 in the vertical direction;

[0116] A third limiting member 42 is connected to one end of the second mounting shaft 25 for abutting against the left end face of the second left upright plate 35, and a fourth limiting member 43 is connected to the other end of the second mounting shaft 25 for abutting against the right end face of the second right upright plate 36; thereby preventing the second buffer seat 19 from moving axially along the second mounting shaft 25.

[0117] The second buffer elastic element 22 is installed between the seat 23 and the second top plate 37. The lower end of the second buffer elastic element 22 is connected to the seat 23, and the upper end of the second buffer elastic element 22 is connected to the second top plate 37. In this embodiment, when the electromagnet 20 descends to contact the steel pipe in the unloading position, the electromagnet 20, the first buffer seat 18, and the second buffer seat 19 all stop descending. At this time, the lifting seat 5 will continue to descend a certain height along with the fixed seat 17. At this time, the first buffer elastic element 21 and the second buffer elastic element 22 will be stretched and deformed, thereby playing a buffering role. Specifically, there are two of each of the first buffer elastic element 21 and the second buffer elastic element 22, and both are springs. The specific structure of the electromagnet 20 is prior art well known to those skilled in the art.

[0118] like Figure 6 , 7 As shown, the electromagnetic adsorption device 6 may also include a blocking component 44, which is connected to the first buffer seat 18 and the second buffer seat 19. The blocking component 44 has a first stop rod portion 45 and a second stop rod portion 46.

[0119] The first stop bar 45 is located on one side of the steel pipe adsorbed on the electromagnet 20 and is used to block the steel pipe adsorbed on the electromagnet 20.

[0120] The second stop bar 46 is located on the other side of the steel pipe adsorbed on the electromagnet 20 and is used to block the steel pipe adsorbed on the electromagnet 20, thereby preventing the steel pipe adsorbed on the electromagnet 20 from rolling to both sides and falling off the electromagnet 20.

[0121] In summary, during the process of transporting and unloading steel pipes into the receiving basket, firstly, the lifting drive mechanism 4 drives the lifting seat 5 to rise, and the moving drive mechanism 3 drives the moving crossbeam 2 to move back and forth on the frame 1 to above the unloading position. Then, the lifting drive mechanism 4 drives the lifting seat 5 to descend so that the electromagnetic adsorption device 6 contacts the steel pipe in the unloading position. Then, the electromagnetic adsorption device 6 is energized and attracts the steel pipe in the unloading position. Finally, the lifting drive mechanism 4 drives the lifting seat 5 to rise, thereby driving the electrically attracted steel pipe to rise. The steel pipe held by the magnetic adsorption device 6 is lifted up. Then, the moving drive mechanism 3 drives the moving crossbeam 2 to move back and forth to above the receiving frame. Then, the lifting drive mechanism 4 drives the lifting seat 5 to lower so that the steel pipe held by the electromagnetic adsorption device 6 is placed into the receiving frame. Then, the electromagnetic adsorption device 6 is de-energized to release the steel pipe, so that the steel pipe falls into the receiving frame. This greatly reduces the height difference of the steel pipe falling into the receiving frame, realizes the handling and unloading of the steel pipe, reduces the noise pollution generated during the unloading of the steel pipe, and can also prevent the steel pipe from being damaged during unloading.
