Description

Technical Field

[0001] This utility model relates to the field of metal processing technology, specifically to a transfer crane for metal processing. Background Technology

[0002] Metalworking refers to the production activities of humans processing materials composed mainly of metallic elements or possessing metallic properties. It is a technological process that transforms metallic materials into items, parts, and components, widely applied in science, industry, art, and handicrafts. In the metalworking process, overhead cranes are often installed within the factory to facilitate the transfer of metal parts. In the existing technology, authorized publication number CN 223303982... U proposes a bridge crane, including a crossbeam and a lifting connection and stabilization mechanism. A winch is installed at the bottom of the crossbeam, and a hook is installed at the bottom of the winch. A fixed plate is movably connected to the rear side of the hook, and a movable plate is movably connected to the front side of the hook. A stabilizing frame is movably connected to the rear side of the fixed plate, and a stabilizing plate is movably connected to the bottom of the inner side of the stabilizing frame. A screw hole is opened at the top of the stabilizing frame, and a screw rod is connected to the internal thread of the screw hole. Although it can transfer metal parts, the tilt angle of the lifting rope is uncertain during the transfer process, which can easily lead to accidents. Even though some transfer cranes are equipped with a lifting rope angle detection component, which contacts the detection component when the lifting rope tilts to a certain angle to avoid the lifting rope angle being too large, the measured angle cannot be displayed in real time, making it inconvenient to use. Utility Model Content

[0003] The technical problem to be solved by this utility model is to overcome the existing defects and provide a metal processing transfer crane that facilitates the relative rotation of the rotating wheel and the tightly fitted suspension rope. While ensuring that the suspension rope angle detection results can be displayed in real time, it reduces the friction between the suspension rope and the detection component, reduces the wear caused by the relative friction between the suspension rope and the detection component during the tilting process, improves the service life of the metal processing transfer crane, and facilitates the use of the transfer crane. It can effectively solve the problems in the background art.

[0004] To achieve the above objectives, the present invention provides the following technical solution: a metal processing transfer trolley, including two tracks distributed front to back, a large trolley slidably connected laterally between the upper ends of the two tracks, a small trolley slidably connected longitudinally to the upper surface of the large trolley, a crane inside the small trolley, and an angle detection mechanism. Angle detection mechanism: It includes a rotating plate, a rotating shell, a sliding frame, and rotating wheels. The rotating plate is rotatably connected to the left end of the trolley. The lower end of the rotating plate is provided with a rotating shell. A sliding frame is longitudinally slidably connected inside the rotating shell. Rotating wheels are rotatably connected between the left and right inner walls of the sliding frame through rotating shafts. The outer arc surfaces of the two rotating wheels are in contact with the crane's lifting rope. By rotating the rotating shell, the arc grooves on the outer arc surfaces of the rotating wheels are always located in the vertical plane where the lifting rope is located, which facilitates the relative rotation of the rotating wheels and the tightly contacted lifting rope. While ensuring that the lifting rope angle detection results can be displayed in real time, it reduces the friction between the lifting rope and the detection component, reduces the wear caused by relative friction between the lifting rope and the detection component during the tilting process, improves the service life of the metal processing transfer crane, and facilitates the use of the transfer crane.

[0005] Furthermore, a microcontroller is provided at the right end of the trolley. The input terminal of the microcontroller is electrically connected to an external power source, and the input terminal of the crane is electrically connected to the output terminal of the microcontroller to control the start and stop of the overall device.

[0006] Furthermore, the angle detection mechanism also includes guide posts, rotating posts, and support plates. The guide posts are respectively disposed on the front and rear sides of the sliding frame and are longitudinally slidably connected to the guide holes on the front and rear sides of the rotating shell. The support plate is disposed between the left and right inner walls of the trolley. A rotating post is rotatably connected in the rotating hole on the surface of the support plate. The upper end of the rotating plate is fixedly connected to the left end of the rotating post, providing support for the movement of the sliding frame and the rotation of the rotating plate.

[0007] Furthermore, the angle detection mechanism also includes a distance sensor and an angle sensor. The distance sensor is installed in the mounting hole on the inner wall of the front side of the rotating shell, and the angle sensor is installed on the right side of the support plate. The detection end of the angle sensor is fixedly connected to the rotating column.

[0008] Furthermore, rubber pads are provided between the upper and lower surfaces of the sliding frame and the inner wall of the rotating shell to seal the sliding frame and the rotating shell, preventing external dust from entering the interior of the rotating shell.

[0009] Furthermore, a torsion spring is movably sleeved on the outer arc surface of the rotating column. The left end of the torsion spring is fixedly connected to the support plate, and the right end of the torsion spring is fixedly connected to the rotating column. Springs are provided between the left and right sides of the sliding frame and the inner wall of the rotating shell. The springs are movably sleeved on the outer arc surface of the guide column to provide elastic limit for the rotating column and the sliding frame.

[0010] Furthermore, the outer arc surface of the wheel is provided with an arc-shaped groove with the same diameter as the crane's lifting rope, which facilitates close contact between the wheel and the lifting rope.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows: This metal processing overhead crane has the following advantages: By rotating the housing, the arc groove on the outer surface of the wheel is always positioned in the vertical plane where the suspension rope is located.

[0014] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0015] Please see Figure 1-5This embodiment provides a technical solution: a metal processing transfer crane, including a track 1, two tracks 1 distributed front and back, a large trolley 2 slidably connected laterally between the upper ends of the two tracks 1, a small trolley 3 slidably connected longitudinally to the upper surface of the large trolley 2, and a crane 4 installed inside the small trolley 3. The track 1, large trolley 2, small trolley 3 and crane 4 constitute a bridge crane structure commonly used in the prior art. The connection method between the large trolley 2 and the two tracks 1 and the connection method between the small trolley 3 and the upper track of the large trolley 2 are both the connection method between the track and the car body in the prior art bridge crane. The crane 4 is started, and the metal part is lifted by winding the lifting rope of the crane 4. Then, the first traveling motor inside the small trolley 3 is started. The output shaft of the first traveling motor drives the wheels of the small trolley 3 to rotate, so that the small trolley 3 moves longitudinally on the surface of the large trolley 2 to adjust the longitudinal position of the metal part. The second traveling motor inside the large trolley 2 is started. The output shaft of the second traveling motor drives the wheels of the large trolley 2 to rotate, so that the large trolley 2 moves laterally on the surface of the track 1 to adjust the lateral position of the metal part, thereby realizing the transfer of the metal part. It also includes an angle detection mechanism 5. Angle detection mechanism 5 includes a rotating plate 51, a rotating shell 52, a sliding frame 53, and rotating wheels 54. The rotating plate 51 is rotatably connected to the left end of the trolley 3. The lower end of the rotating plate 51 is provided with a rotating shell 52. A sliding frame 53 is longitudinally slidably connected inside the rotating shell 52. Rotating wheels 54 are rotatably connected between the left and right inner walls of the sliding frame 53 via rotating shafts. The outer arc surfaces of both rotating wheels 54 are in contact with the lifting rope of the crane 4. During the transfer process, when the lifting rope of the crane 4 tilts, the lifting rope applies a force to the rotating wheels 54, pushing the sliding frame 53 to slide inside the rotating shell 52. The rotating shell 52 drives the rotating plate 51 to rotate, providing clearance for the tilt of the lifting rope. By detecting the distance between the left side of the sliding frame 53 and the left inner wall of the rotating shell 52, the movement distance of the sliding frame 53 is determined. The contact point between the lifting rope and the rotating wheel 54 is then monitored. The position is then determined by detecting the rotation angle of the rotating shell 52 to determine the left-right and up-down positions of the contact point between the suspension rope and the rotating wheel 54, thus obtaining the three-dimensional spatial position of the contact point between the suspension rope and the rotating wheel 54. Combined with the position of the fixed end of the suspension rope, the angle between the line connecting the contact point and the fixed point and the vertical direction is obtained. The line connecting the contact point and the fixed point coincides with the suspension rope, thus determining the tilt angle of the suspension rope. During the detection process, the outer arc surface of the rotating wheel 54 is always in close contact with the suspension rope to ensure the accuracy of the detection results. At the same time, the rotation of the rotating shell 52 ensures that the arc groove on the outer arc surface of the rotating wheel 54 is always located in the vertical plane where the suspension rope is located, which facilitates the relative rotation of the rotating wheel 54 and the suspension rope, reduces the friction between the suspension rope and the detection component, and reduces the wear caused by the relative friction between the suspension rope and the detection component during the tilting process. The suspension rope can be a steel wire rope. The right end of the trolley 3 is equipped with a microcontroller 8. The input terminal of the microcontroller 8 is electrically connected to an external power source. The input terminal of the crane 4 is electrically connected to the output terminal of the microcontroller 8. The input terminals of the first traveling motor of the trolley 3 and the second traveling motor of the crane 2 are both electrically connected to the output terminal of the microcontroller 8 to control the start and stop of the overall device. The angle detection mechanism 5 also includes a guide post 55, a rotating post 56, and a support plate 57. The guide post 55 is respectively disposed on the front and rear sides of the sliding frame 53. The guide post 55 is longitudinally slidably connected to the guide holes on the front and rear sides of the rotating shell 52. The support plate 57 is disposed between the left and right inner walls of the trolley 3. The rotating post 56 is rotatably connected in the rotating hole on the surface of the support plate 57. The upper end of the rotating plate 51 is fixedly connected to the left end of the rotating post 56. The longitudinal sliding of the guide post 55 with the guide hole of the rotating shell 52 provides guiding support for the movement of the sliding frame 53. The relative rotation of the rotating post 56 and the support plate 57 provides guiding support for the rotation of the rotating plate 51. The angle detection mechanism 5 also includes a distance sensor 58 and an angle sensor 59. The distance sensor 58 is installed in the mounting hole on the inner wall of the front side of the rotating shell 52, and the angle sensor 59 is installed on the right side of the support plate 57. The detection end of the angle sensor 59 is fixedly connected to the rotating column 56. The output ends of both the distance sensor 58 and the angle sensor 59 are electrically connected to the input end of the microcontroller 8. The distance sensor 58 detects the distance between the left side of the sliding frame 53 and the inner wall of the left side of the rotating shell 52 to determine the moving distance of the sliding frame 53 and to determine the front and rear positions of the contact point between the suspension rope and the rotating wheel 54. The angle sensor 59 detects the rotation angle of the rotating column 56 to determine the left and right and up and down positions of the contact point between the suspension rope and the rotating wheel 54. Rubber pads 6 are provided between the upper and lower surfaces of the sliding frame 53 and the inner wall of the rotating shell 52. During the movement of the sliding frame 53, the deformation of the rubber pads 6 is used to seal the sliding frame 53 and the rotating shell 52, so as to prevent external dust from entering the interior of the rotating shell 52 and affecting the test results. A torsion spring 7 is movably sleeved on the outer arc surface of the rotating column 56. The left end of the torsion spring 7 is fixedly connected to the support plate 57, and the right end of the torsion spring 7 is fixedly connected to the rotating column 56. Springs 9 are provided between the left and right sides of the sliding frame 53 and the inner wall of the rotating shell 52. The springs 9 are movably sleeved on the outer arc surface of the guide column 55. The torsion of the torsion spring 7 provides elastic limit for the rotating column 56, and the elastic force of the spring 9 provides elastic limit for the sliding frame 53. The longitudinal position of the sliding frame 53 when in contact and the initial angle of the rotating shell 52 are limited. The ends of the torsion spring 7 are fixedly connected to the rotating column 56 and the support plate 57 by connecting bolt 1, and the ends of the spring 9 are fixedly connected to the sliding frame 53 and the rotating shell 52 by connecting bolt 2. The torsion spring 7 and the spring 9 are disassembled, replaced or maintained periodically by rotating connecting bolt 1 and connecting bolt 2 to avoid aging and corrosion affecting the normal operation of the torsion spring 7 and the spring 9. The outer arc surface of the wheel 54 is provided with an arc groove with the same diameter as the lifting rope of the crane 4 to ensure close contact between the wheel 54 and the lifting rope.

[0016] The working principle of the metal processing overhead crane provided by this utility model is as follows: During the metal processing, the metal part is fixed to the lower end of the hook of the crane 4. The crane 4 is started by the microcontroller 8, and the metal part is lifted by the winding of the crane 4's hoisting rope. Then, the first traveling motor inside the trolley 3 is started. The output shaft of the first traveling motor drives the wheels of the trolley 3 to rotate, so that the trolley 3 moves longitudinally on the surface of the trolley 2, adjusting the longitudinal position of the metal part. The second traveling motor inside the trolley 2 is started. The output shaft of the second traveling motor drives the wheels of the trolley 2 to rotate, so that the trolley 2 moves laterally on the surface of the track 1, adjusting the lateral position of the metal part, thus realizing the transfer of the metal part. During the transfer process, when the hoisting rope of the crane 4 tilts, the hoisting rope applies a force to the rotating wheel 54, pushing the sliding frame 53 to slide inside the rotating shell 52. The rotating shell 52 drives the rotating plate 51 to rotate around the rotating column 56 as the center, providing support for the tilting of the hoisting rope. To provide clearance, the distance between the left side of the sliding frame 53 and the left inner wall of the rotating shell 52 is detected by the distance sensor 58 to determine the moving distance of the sliding frame 53, and the front and rear positions of the contact point between the suspension rope and the rotating wheel 54 are determined. The rotation angle of the rotating column 56 is detected by the angle sensor 59 to determine the left and right and up and down positions of the contact point between the suspension rope and the rotating wheel 54, thus obtaining the three-dimensional spatial position of the contact point between the suspension rope and the rotating wheel 54. Combined with the position of the fixed end of the suspension rope, the angle between the line connecting the contact point and the fixed point and the vertical direction is obtained to determine the tilt angle of the suspension rope. During the detection process, the outer arc surface of the rotating wheel 54 is always in close contact with the suspension rope to ensure the accuracy of the detection results. At the same time, the rotation of the rotating shell 52 ensures that the arc groove of the outer arc surface of the rotating wheel 54 is always located in the vertical plane where the suspension rope is located, which facilitates the relative rotation of the rotating wheel 54 and the suspension rope, reduces the friction between the suspension rope and the detection component, and reduces the wear caused by the relative friction between the suspension rope and the detection component during the tilting process.

[0017] It is worth noting that the microcontroller 8 disclosed in the above embodiments can be an STM32F107 microcontroller. The crane 4, the distance sensor 58, and the angle sensor 59 can be freely configured according to the actual application scenario. The crane 4 can be an LDA type 1-20t crane, the distance sensor 58 can be a T150HJG-CGQ type reflective laser distance sensor, and the angle sensor 59 can be an HW225D type angle sensor. The microcontroller 8 controls the operation of the crane 4, the distance sensor 58, and the angle sensor 59 using methods commonly used in the prior art.
