Description

Technical Field

[0001] This utility model relates to the field of crane technology, and in particular to an electromagnetic girder bridge crane. Background Technology

[0002] Bridge cranes are widely used material handling equipment in the industrial field. Electromagnetic girder bridge cranes, in particular, use electromagnetic chucks to quickly grasp and move magnetic materials, making them especially suitable for steel mills and metal processing workshops. Traditional electromagnetic girder bridge cranes typically consist of a bridge frame, a trolley traveling mechanism, a trolley, an electromagnetic girder, and a lifting mechanism. The electromagnetic girder usually uses a fixed structure, meaning the magnetic pole spacing and girder length are preset, and material grasping is achieved by adjusting the crane position. However, during current lifting operations, the electromagnetic girder sways as it moves the suspended load, potentially affecting the safety of on-site operators. Furthermore, after lifting objects, dust and impurities accumulate on the lower surface of the electromagnetic chuck, which usually requires manual wiping, a tedious process.

[0003] A search revealed a utility model patent document, CN212076209U, which discloses an anti-sway structure for an electromagnetic chuck of a bridge crane. The structure includes a connecting plate and a column. The connecting plate is fixedly connected to the lower end face of the crossbeam in the electromagnetic chuck structure, and a vertically penetrating limiting hole is provided on the connecting plate. The lower end of the column is fixedly connected to the electromagnetic chuck body in the electromagnetic chuck structure, and the upper end of the column passes through the limiting hole and is located above the limiting hole. The limiting hole and the column are in clearance fit. This utility model, by providing a connecting plate on the lower end face of the crossbeam and a fixed column on the upper end face of the electromagnetic chuck body, with the upper end of the column located within the limiting hole, ensures that if the electromagnetic chuck body sways during operation, the column will also sway, and the upper end of the column will contact the inner wall of the limiting hole. This restricts the swaying of the upper end of the column, thereby restricting the swaying of the electromagnetic chuck body and achieving the purpose of anti-swaying.

[0004] The aforementioned anti-sway structure only works on the electromagnetic chuck itself; the swaying problem of the electromagnetic hanging beam above during suspension is not solved. Utility Model Content

[0005] The purpose of this invention is to provide an electromagnetic girder bridge crane that can ensure the stability of the electromagnetic girder during the suspension and movement of the hoisted load, preventing swaying.

[0006] The present invention adopts the following technical solution:

[0007] The electromagnetic suspension beam bridge crane includes a bridge frame, a trolley frame, and an electromagnetic suspension beam. The trolley frame is installed on the upper surface of the bridge frame, and the electromagnetic suspension beam is located below the bridge frame. A lifting mechanism is installed on the upper surface of the middle part of the trolley frame. Pulley assemblies 1 are symmetrically arranged on both sides of the lifting mechanism and installed on the upper surface of the trolley frame. Pulley assemblies 2 are symmetrically installed on the upper surface of the electromagnetic suspension beam. Anti-sway components are symmetrically arranged between the trolley frame and the electromagnetic suspension beam to prevent the electromagnetic suspension beam from swaying during suspension.

[0008] Below the electromagnetic hanging beam are several electromagnetic adsorption mechanisms arranged in a linear pattern. Each electromagnetic adsorption mechanism includes an electromagnetic chuck and a support plate. The support plate is installed on the upper surface of the electromagnetic chuck. Drive mechanisms are symmetrically installed on both sides of the electromagnetic chuck. A cleaning component for removing dust and impurities from the lower surface of the electromagnetic chuck is installed between the two drive mechanisms.

[0009] Optionally, the anti-sway assembly includes a guide cylinder and a guide shaft. The guide cylinder vertically penetrates the trolley frame and is fixed to the trolley frame. The guide shaft is slidably disposed inside the guide cylinder. A connecting seat is fixedly installed on the lower end face of the guide shaft. The connecting seat is fixedly installed on the upper surface of the electromagnetic hanging beam.

[0010] Optionally, two sets of lifting chains are symmetrically fixedly installed on the upper surface of the support plate, and lifting rings are installed at the upper ends of the two adjacent lifting chains.

[0011] Optionally, several sets of hooks are symmetrically fixed on both sides of the electromagnetic hanging beam, with the lifting rings and hooks matched, and the hooks hanging on the hooks.

[0012] Optionally, the drive assembly includes a U-shaped support frame, a support rod, and a guide rail. A connecting plate is fixedly installed on the side of the U-shaped support frame, and the connecting plate is installed on the outer side of the support plate. The guide rail is installed on the outer side of the electromagnetic chuck.

[0013] Optionally, a lead screw is rotatably installed inside the U-shaped support frame, and a slider is threaded on the surface of the lead screw. The slider slides on the surface of the U-shaped support frame, and a support shaft is fixedly installed on the upper end face of the support plate. The support shaft passes through the slider and slides.

[0014] Optionally, a groove is provided on the outer side of the slide rail. The groove is divided into two parts: one part is set horizontally and the other part is set upwardly. A support plate is set on the outside of the slide rail, and a guide post is fixedly set on the support plate relative to the outer side of the slide rail. The guide post is adapted to the groove and is slidably set in the groove.

[0015] Optionally, the cleaning assembly includes a rotating shaft, a brush roller, and an air inlet pipe. The rotating shaft is hollow, with one end connected to the outside, and is rotatably mounted between two support rods. The brush roller is fixedly mounted on the circumferential surface of the rotating shaft.

[0016] Optionally, a brush for cleaning the lower surface of the electromagnetic chuck is provided on the circumferential surface of the brush roller. A through hole 1 communicating with the inner cavity is provided on the circumferential surface of the brush roller, and several through holes 2 communicating with the inner cavity are provided on the circumferential surface of the rotating shaft.

In this utility model, after the hoisting operation is completed, the brush roller is driven by the support rod to enter the lower surface of the electromagnetic chuck from the side, and the brush on the circumferential surface of the brush roller contacts the lower surface of the electromagnetic chuck. Then, the motor is started to drive the brush roller to rotate. With the air blowing through the air inlet pipe, the dust and impurities on the lower surface of the electromagnetic chuck can be cleaned, ensuring the electromagnetic chuck's effect on the hoisting and adsorption of the next batch of heavy objects.

[0031] The principles and spirit of this utility model will be explained in detail below with reference to several representative embodiments.

[0032] Please see Figure 1-9 The present invention will now be described in detail with reference to the accompanying drawings and embodiments:

[0033] like Figure 1-5 As shown, the electromagnetic girder bridge crane includes a bridge frame 1, a trolley frame 2, and an electromagnetic girder 4. The trolley frame 2 is installed on the upper surface of the bridge frame 1 and can move laterally on the bridge frame 1. The electromagnetic girder 4 is located below the bridge frame 1. A hoisting mechanism 21 is installed on the upper surface of the middle part of the trolley frame 2. Pulley assemblies 1 22 are symmetrically arranged on both sides of the hoisting mechanism 21 and installed on the upper surface of the trolley frame 2. Pulley assemblies 23 are symmetrically installed on the upper surface of the electromagnetic girder 4. The hoisting wire rope in the hoisting mechanism 21 is wound on the pulley assembly 1 22 and the pulley assembly 23. The electromagnetic girder 4 is lifted and hoisted by the hoisting mechanism 21.

[0034] Anti-sway components 3 are symmetrically arranged between the trolley frame 2 and the electromagnetic suspension beam 4 to prevent the electromagnetic suspension beam 4 from swaying during suspension.

[0035] Several electromagnetic adsorption mechanisms 5 are arranged linearly below the electromagnetic hanging beam 4. The electromagnetic adsorption mechanism 5 includes an electromagnetic chuck 51 and a support plate 52. The support plate 52 is fixedly installed on the upper surface of the electromagnetic chuck 51. Drive mechanisms are symmetrically installed on both sides of the electromagnetic chuck 51. A cleaning component 7 for removing dust and impurities from the lower surface of the electromagnetic chuck 51 is installed between the two drive mechanisms.

[0036] The aforementioned hoisting mechanism 21, pulley assembly 1 22 and pulley assembly 23 are all existing technologies and will not be described in detail here.

[0037] like Figure 4 As shown, in this utility model, the anti-sway component 3 includes a guide cylinder 31 and a guide shaft 32. The guide cylinder 31 vertically penetrates the trolley frame 2 and is fixed to the trolley frame 2. The guide shaft 32 is slidably disposed inside the guide cylinder 31. A connecting seat 33 is fixedly installed on the lower end face of the guide shaft 32. The connecting seat 33 is fixedly installed on the upper surface of the electromagnetic hanging beam 4.

[0038] Specifically, when the hoisting mechanism 21 drives the electromagnetic hanging beam 4 below to perform lifting operations, the pulley assembly 1 22 and the pulley assembly 23 work together. At this time, the guide shaft 32 slides up and down in the guide cylinder 31 to ensure that the electromagnetic hanging beam 4 can move vertically during the hoisting operation, thereby improving the hoisting stability of the heavy objects below.

[0039] like Figure 3 and Figure 5 As shown, in this embodiment, two sets of lifting chains 53 are symmetrically fixedly installed on the upper surface of the support plate 52, and lifting rings 54 are installed on the upper ends of the two adjacent lifting chains 53.

[0040] Several sets of hooks 41 are symmetrically fixed on both sides of the electromagnetic hanging beam 4. The lifting ring 54 is adapted to the hook 41, and the hook is hung on the hook 41.

[0041] like Figure 5-6 As shown, in this embodiment, the drive assembly includes a U-shaped support frame 62, a support rod 63, and a guide rail 61. A connecting plate 621 is fixedly provided on the side of the U-shaped support frame 62. The connecting plate 621 is fixedly installed on the outer side of the support plate 52 by bolts. The guide rail 61 is fixedly installed on the outer side of the electromagnetic chuck 51.

[0042] like Figure 5-6 As shown, in this embodiment, a lead screw 66 is rotatably arranged inside the U-shaped support frame 62, and a slider 622 is threaded on the surface of the lead screw 66. The slider 622 slides on the surface of the U-shaped support frame 62. A motor 623 with an output shaft fixed to one end of the lead screw 66 is fixed on the outer side of the U-shaped support frame 62. The motor 623 drives the lead screw 66 to rotate, thereby driving the slider 622 to move.

[0043] like Figure 5-6 As shown, in this embodiment, a groove 611 is provided on the outer side of the guide rail 61. The groove 611 is divided into two parts, one part is arranged horizontally and the other part is bent upward.

[0044] like Figure 5-6As shown, in this embodiment, the support plate 52 is disposed on the outside of the guide rail 61, and a guide post 631 is fixedly disposed on the outer side of the support plate 52 relative to the guide rail 61. The guide post 631 is adapted to the slide groove 611 and is slidably disposed in the slide groove 611.

[0045] A support shaft 632 is fixedly installed on the upper end face of the support plate 52. The support shaft 632 passes through the slider 622 and is slidably engaged. A nut 634 is threaded on the upper end of the support shaft 632. A spring 633 is installed between the nut 634 and the slider 622 and is sleeved on the circumference of the support shaft 632. The spring 633 is used to assist the support rod 63 in resetting.

[0046] Specifically, the rotation of the lead screw 66 drives the movement of the slider 622, which in turn drives the support shaft 632 to move. The support shaft 632 drives the support rod 63 to follow the slider 622, and the support rod 63 drives the guide column 631 to move along the trajectory of the slide groove 611.

[0047] like Figure 7-9 As shown, in this embodiment, the cleaning component 7 includes a rotating shaft 73, a brush roller 71, and an air inlet pipe 72. The rotating shaft 73 is hollow, with one end communicating with the outside. The rotating shaft 73 is rotatably mounted between two support rods 63. The brush roller 71 is fixedly mounted on the circumferential surface of the rotating shaft 73 and rotates with the rotating shaft 73. A second motor 65 is fixedly mounted on the outer side of one support rod 63. The output shaft of the second motor 65 is fixed to one closed end of the rotating shaft 73, and the rotating shaft 73 is driven to rotate by the second motor 65.

[0048] like Figure 7-9 As shown, in this embodiment, a brush for cleaning the lower surface of the electromagnetic chuck 51 is provided on the circumferential surface of the brush roller 71, and a through hole 711 communicating with the inner cavity is provided on the circumferential surface of the brush roller 71.

[0049] Several through holes 731 communicating with the inner cavity are provided on the circumferential surface of the rotating shaft 73. Through holes 711 and through holes 731 are connected.

[0050] like Figure 7-9 As shown, in this embodiment, a connecting pipe 721 is fixedly provided on the outer side of the other support rod 63. The connecting pipe 721 communicates with the inner cavity of the rotating shaft 73. The connecting pipe 721 is fixedly connected to the lower end of the air inlet pipe 72 and communicates with the air inlet pipe 72. The other end of the air inlet pipe 72 is connected to an external air inlet mechanism. The air inlet pipe 72 is inflated by the external air inlet mechanism, so that the brush roller 71 blows air onto the lower surface of the electromagnetic chuck 51 while rotating to clean it, thereby improving the cleaning effect.

[0051] The aforementioned air intake mechanism is existing technology and will not be drawn or described here.

[0052] Specifically, during hoisting operations, the guide column 631 is positioned within the groove 611 of the curved section. At this time, the brush roller 71 is located on the right side of the electromagnetic chuck 51, which does not affect the hoisting operation of the electromagnetic chuck 51. After hoisting, when it is necessary to clean the lower surface of the electromagnetic chuck 51, motor 1 623 and motor 2 65 are started, causing the lead screw 66 to drive the slider 622 to move. At the same time, the rotating shaft 73 drives the brush roller 71 to rotate. The movement of the slider 622 will cause the guide column 631 below to move into the groove 611 of the transverse section. During the movement of the guide column 631, the spring 633 is stretched, and the support rods 63 on both sides will drive the brush roller 71 to move to the lower surface of the electromagnetic chuck 51. This, in conjunction with the air inlet pipe 72, removes dust and impurities from the electromagnetic chuck 51. After cleaning, motor 1 623 drives the lead screw 66 to rotate in the opposite direction, causing the support rod 63 to return to the right side position of the electromagnetic chuck 51.
