Technical Field
[0001] This utility model belongs to the technical field of crane component processing equipment, and in particular relates to a groove pressing device for a crane end beam. Background Technology
[0002] Crane end beams are essential components of existing cranes. Currently, when processing box-type crane end beams, they are usually welded together from several steel plates. Specifically, box-type crane end beams typically include a horizontally positioned base plate, with two vertically opposite web plates welded to both sides of the base plate along its length to form a U-shaped beam. After welding a cover plate opposite to the top plate to the top of the U-shaped beam, the main structure of the crane end beam is formed. However, using the above processing method, welding the two web plates to the base plate to form the U-shaped beam takes a long time, and the processing efficiency needs to be improved. Therefore, there are still shortcomings and deficiencies in the existing technology. Utility Model Content
[0003] The purpose of this invention is to provide a groove pressing device for the end beam of a crane to solve the problems mentioned in the background art.
[0004] The technical solution adopted by this utility model to solve the above problems is as follows: A grooving device for a crane end beam includes a frame, a grooving mold core parallel to the length direction of the frame is provided at the top of the frame, a vertically distributed first electric telescopic mechanism is installed between the top of the grooving mold core and the frame, and two rotatable bearing rollers parallel to the grooving mold core are installed in the frame below the grooving mold core, the two bearing rollers are arranged opposite each other and spaced apart. A guide frame parallel to the grooving mold core is installed inside the frame located outside one side of the grooving mold core. A sliding trolley that can reciprocate along the length of the frame is slidably connected to the guide frame. A vertically distributed lifting mechanism is installed on the side of the sliding trolley near the grooving mold core. A horizontally arranged support plate is installed on the lifting mechanism. An adsorption mechanism is installed on the bottom surface of the support plate.
[0005] Furthermore, a support frame is installed on one side of the frame, parallel to the bearing roller. Both ends of one of the bearing rollers are rotatably connected to the support frame. The support frame is slidably connected to the frame along the width direction. Guide seats are fixedly mounted on the frame at both ends of the support frame. A guide rod parallel to the width direction of the frame is slidably connected to each guide seat. The end of the guide rod near the support frame is fixedly connected to the support frame. A locking mechanism that can simultaneously tighten or loosen the two guide rods is installed between the ends of the two guide rods away from the support frame.
[0006] Furthermore, the locking mechanism includes a locking rod that is parallel to the support frame and can slide back and forth along the length of the frame. Both ends of the locking rod are provided with wedge-shaped blocks fixed on the locking rod between them and the guide rod.
[0007] Furthermore, one end of the locking rod is connected to a second electric telescopic mechanism mounted on the frame, and the second electric telescopic mechanism is parallel to the length direction of the frame.
[0008] Furthermore, both ends of the guide frame are located outside the machine frame, and a fixed pulley is installed at one end of the guide frame. Two drums that can rotate synchronously and can rotate in both directions are installed at the other end of the guide frame. Each drum is parallel to the width direction of the machine frame, and one drum is a winding drum and the other is an unwinding drum. Each drum is also wound with a steel wire rope. One end of the steel wire rope away from the drum is connected to the sliding trolley, and the other end of the steel wire rope away from the drum passes around the fixed pulley and is connected to the sliding trolley.
[0009] Furthermore, on the other side of each bearing roller, several sets of guide wheel mechanisms are installed inside the frame and distributed along the length of the frame.
[0010] Furthermore, each guide wheel mechanism includes a fixed plate mounted inside the frame. Each fixed plate is equipped with a vertical plate, and each vertical plate is equipped with a threaded rod that is parallel to the width direction of the frame and slides through the vertical plate. Locking nuts are threaded onto the threaded rods located on both sides of the vertical plate. A U-shaped frame with a U-shaped opening facing the bearing roller is installed at the end of each threaded rod near the bearing roller. Guide wheels are rotatably connected inside each U-shaped frame, and the axial lines of the guide wheels are vertically distributed.
[0011] Furthermore, the lifting mechanism is a screw jack, and the adsorption mechanism is an electromagnetic chuck.
[0012] The beneficial effects of this utility model by adopting the above technical solution are as follows: In use, the steel plate to be processed can be placed horizontally on two bearing rollers. Then, as the first electric telescopic mechanism drives the grooving mold core to descend, the steel plate can be pressed into a U-shaped beam with an integral structure.

[0015] To make the objectives, technical solutions, and beneficial effects of this utility model clearer, the embodiments of this utility model will be described in further detail below with reference to the accompanying drawings.
[0016] like Figures 1 to 7 As shown, this utility model provides a groove pressing device for the end beam of a crane. Specifically, when in use, this utility model can be connected to an external electrical control system to supply power and control the start and stop of various electrical components included in this utility model.
[0017] This utility model includes a frame 10, which includes a horizontally opposite base frame and a top frame. Several vertically opposite support legs are installed between the top frame and the base frame. A grooving mold core 1, which is parallel to the length direction of the frame 10, is provided at the top of the frame 10. The grooving mold core 1 is a strip beam. A vertically distributed first electric telescopic mechanism 2 is installed between the top of the grooving mold core 1 and the frame 10. Specifically, the first electric telescopic mechanism 2 can be configured as several vertically opposite hydraulic cylinders that are synchronously telescopic and controlled by an electric control system. Several hydraulic cylinders can share a set of hydraulic pump stations, and the bottom end of each hydraulic cylinder is a movable end that is connected to the grooving mold core 1. In the initial state, the telescopic end of the hydraulic cylinder is in the retracted state.
[0018] Two rotatable bearing rollers 3 are installed in the frame 10 located below the grooving mold core 1. The two bearing rollers 3 are arranged opposite each other and spaced apart. Specifically, the two bearing rollers 3 are installed on the inner bottom surface of the frame 10. In use, the steel plate to be processed can be placed horizontally on the two bearing rollers 3. Then, when the grooving mold core 1 is driven down by the first electric telescopic mechanism 2, the steel plate can be pressed into a U-shaped beam with an integral structure. Compared with the existing technology, this processing method can save processing time and improve the processing efficiency of the crane end beam. In addition, since the U-shaped beam is an integral structure, the overall stability of the U-shaped beam structure can also be improved.
[0019] Secondly, a guide frame 4 parallel to the grooving mold core 1 is installed inside the frame 10 located outside one side of the grooving mold core 1. A sliding trolley 5 that can reciprocate along the length of the frame 10 is slidably connected to the guide frame 4. A vertically distributed lifting mechanism 8 is installed on the side of the sliding trolley 5 near the grooving mold core 1. Specifically, the lifting mechanism 8 is also located outside one side of the grooving mold core 1. That is, when the sliding trolley 5 moves along the length of the frame 10 on the guide frame 4, the grooving mold core 1 does not affect the movement of the lifting mechanism 8 with the movement of the sliding trolley 5. A horizontally arranged bearing plate 11 is installed on the lifting mechanism 8, and an adsorption mechanism 9 is installed on the bottom surface of the bearing plate 11.
[0020] Specifically, the end of the support plate 11 away from the sliding trolley 5 extends away from the sliding trolley 5, that is, the length direction of the support plate 11 is parallel to the width direction of the frame 10; the adsorption mechanism 9 can be set as an electromagnetic chuck; and the lifting mechanism 8 can be set as a screw jack in the prior art. During assembly, the support plate 11 is connected to the bottom end of the screw in the screw jack, and four vertically opposite movable rods 18 are fixed on the top surface of the support plate 11. The four movable rods 18 are slidably sleeved between each other and fixed on the sliding trolley 5. Fixed frame 19; In use, when the lifting mechanism 8 is activated, it can drive the bearing plate 11 to rise and fall in the vertical direction. The movable rod 18 cooperates with the fixed frame 19 to improve the stability of the bearing plate 11 during the lifting process, so as to facilitate the adsorption mechanism 9 to adsorb the steel plate to be processed. After the adsorption mechanism 9 adsorbs the steel plate, the lifting mechanism 8 can also adjust the top surface height of the bearing plate 11 to be lower than the bottom surface height of the grooving mold core 1 in the initial state, so as to prevent the grooving mold core 1 from affecting the synchronous movement of the bearing plate 11 as the sliding trolley 5 moves.
[0021] By setting a guide frame 4 and sliding a trolley 5 on the guide frame 4, when the trolley 5 moves along the length of the frame 10 on the guide frame 4, it can indirectly drive the adsorption mechanism 9 to move along the length of the frame 10. In this way, after the adsorption mechanism 9 adsorbs and fixes the steel plate to be processed, the trolley 5 can drive the adsorption mechanism 9 to place the steel plate to be processed horizontally on the two bearing rollers 3, which facilitates the subsequent grooving processing of the steel plate. In addition, after the steel plate to be processed is formed into a U-shaped beam between the two bearing rollers 3, the U-shaped opening of the U-shaped beam is higher than the bearing rollers 3. In this way, when the next steel plate to be processed is placed horizontally on the two bearing rollers 3, the U-shaped beam formed between the two bearing rollers 3 can be pushed to move and unload at the same time. In addition, a roller conveyor adapted to the unloading position of the U-shaped beam can be set on one side of the frame 10 to facilitate the subsequent transport of the U-shaped beam.
[0022] Furthermore, such as Figure 2As shown, a support frame 12 is installed on one side of the frame 10, parallel to the bearing roller 3. Both ends of one of the bearing rollers 3 are rotatably connected to the support frame 12. The support frame 12 can slide along the width direction of the frame 10 via a groove opened on the inner bottom surface of the frame 10. Guide seats 13, fixed to the frame 10, are provided at both ends of the support frame 12. Each guide seat 13 has a guide rod 14 slidably connected to it, parallel to the width direction of the frame 10. The end of the guide rod 14 closest to the support frame 12 is fixedly connected to the support frame 12. A locking mechanism 6, capable of simultaneously tightening or loosening the two guide rods 14, is installed between the ends of the two guide rods 14 furthest from the support frame 12. Specifically, in the initial state… At this point, the locking mechanism 6 and the guide rod 14 are in a loose state. Before pressing the steel plate to be processed using the grooving die core 1, the locking mechanism 6 can be tightened against the guide rod 14 to fix the position of the support frame 12 on the frame 10. At this time, the position between the two bearing rollers 3 is fixed to avoid affecting the grooving die core 1 in grooving the steel plate to be processed. Then, after pressing the steel plate to be processed using the grooving die core 1, the locking mechanism 6 is released from the guide rod 14. At this time, since the support frame 12 can slide along the width direction of the frame 10, the bearing rollers 3 installed on the support frame 12 have a certain amount of room for movement in the width direction of the frame 10, which facilitates the movement of the formed U-shaped beam between the two bearing rollers 3 for feeding.
[0023] The specific configuration of the locking mechanism 6 is as follows: Figure 2 As shown, the locking mechanism 6 includes a locking rod 61 that is parallel to the support frame 12 and can reciprocate along the length of the frame 10. Specifically, the locking rod 61 can be slidably connected to the frame 10 along the length of the frame 10 via a groove opened on the inner bottom surface of the frame 10. Wedge-shaped blocks 62 fixed on the locking rod 61 are provided at both ends of the locking rod 61 and between the locking rod 61 and the guide rod 14. The specific arrangement of the wedge-shaped blocks 62 is as follows: Figure 2 As shown; specifically, in use, by moving the locking rod 61 along the length of the frame 10, when the wider position of the wedge block 62 contacts the guide rod 14, the guide rod 14 can be pressed against it to fix the position of the support frame 12 on the frame 10; and by moving the locking rod 61 in the opposite direction, when the wider position of the wedge block 62 is far away from the guide rod 14, the guide rod 14 can be released.
[0024] Furthermore, such as Figure 2As shown, one end of the locking rod 61 is connected to a second electric telescopic mechanism 63 mounted on the frame 10. The second electric telescopic mechanism 63 is parallel to the length direction of the frame 10. Specifically, the second electric telescopic mechanism 63 can be configured as a hydraulic cylinder. In use, the extension and retraction of the second electric telescopic mechanism 63 can drive the locking rod 61 to move back and forth along the length direction of the frame 10, so that the wedge block 62 can press against or release the guide rod 14.
[0025] The specific configuration of the sliding trolley 5 being able to move along the length of the frame 10 on the guide frame 4 is as follows: Figure 1 , Figures 4 to 6 As shown, both ends of the guide frame 4 are located outside the frame 10, and a fixed pulley 15 is installed at one end of the guide frame 4. Two synchronously rotating and reversible drums 16 are installed at the other end of the guide frame 4. Each drum 16 is parallel to the width direction of the frame 10, and one drum 16 is a take-up drum, while the other is a release drum. Specifically, each drum 16 has a first gear 20 fitted onto its end near the guide frame 4 after passing through the guide frame 4. A reversible drive motor is installed on the guide frame 4. The output shaft of the machine is fitted with second gears 21 that can mesh with the two first gears 20 respectively. In use, when the drive motor is started, it can drive the two drums 16 to rotate synchronously in the same direction. Furthermore, each drum 16 is wound with a steel wire rope 17. One end of the steel wire rope 17 away from the drum 16 is connected to the sliding trolley 5, and the other end of the steel wire rope 17 away from the drum 16 passes over the fixed pulley 15 and is connected to the sliding trolley 5. Specifically, the winding method of the steel wire rope 17 on the drum 16 is as follows: Figure 4 As shown, in use, one of the drums 16 is an unwinding drum, which can unwind the wire rope 17, while the other drum 16 is a winding drum, which can simultaneously wind the wire rope 17, so as to drive the sliding trolley 5 to move back and forth along the length of the frame 10 on the guide frame 4.
[0026] Furthermore, such as Figure 2 and Figure 3 As shown, each of the opposite sides of each bearing roller 3 is provided with several sets of guide wheel mechanisms 7 mounted inside the frame 10 and distributed along the length of the frame 10. Specifically, during use, when the steel plate to be processed is placed horizontally on the two bearing rollers 3, the guide wheel mechanism 7 can guide both sides of the steel plate to be processed to prevent the position of the steel plate from shifting.
[0027] The specific configuration of guide wheel mechanism 7 is as follows: Figure 2 and Figure 3As shown, each guide wheel mechanism 7 includes a fixed plate 71 mounted within the frame 10. A vertical plate 72 is mounted on each fixed plate 71. A threaded rod 73, parallel to the width direction of the frame 10 and slidingly passing through the vertical plate 72, is mounted on each vertical plate 72. Locking nuts 76 are threadedly connected to the threaded rods 73 on both sides of the vertical plate 72. When the locking nuts 76 are tightened against the vertical plate 72, the position of the threaded rod 73 is fixed. A U-shaped opening is installed at the end of the threaded rod 73 closest to the bearing roller 3, facing the bearing roller. The U-shaped frame 74 of the roller 3 has guide wheels 75 rotatably connected inside it. The axial lines of the guide wheels 75 are all vertically distributed. Specifically, the edge of the guide wheel 75 is located outside the U-shaped opening of the U-shaped frame 74. By setting the guide wheels 75, the steel plate to be processed can be guided. Secondly, when the locking nut 76 is loosened, the threaded rod 73 can be slid along the width direction of the frame 10 to adjust the position of the guide wheel 75, so that the guide wheel mechanism 7 can be adapted to guide steel plates of different widths to be processed.
