Description

Technical Field

[0001] This utility model belongs to the field of profile steel processing equipment, and specifically relates to a profile steel weld cleaning device. Background Technology

[0002] During the production of structural steel sections, unevenness and protruding weld slag are common problems at the weld ends, necessitating the use of cleaning devices to effectively remove the weld slag. Existing cleaning devices typically involve securing the structural steel section firmly and then using a scraper or scraper blade to clean the weld. However, these devices suffer from low cleaning efficiency, inconvenient structural steel position adjustment, and insecure steel fixation, which negatively impacts the effectiveness of weld slag removal. Utility Model Content

[0003] In order to overcome the shortcomings of the existing technology, this utility model aims to provide a steel section weld cleaning device. This device can adapt to the weld cleaning operation of different types of steel sections. The adjustment of the shovel is very convenient. It can effectively collect the residual material and debris generated during cleaning, thereby significantly improving the processing and production efficiency of steel sections.

[0004] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0005] A steel weld cleaning device includes a frame, a shovel, and a steel fixing assembly. A housing is mounted on top of the frame, with a feed inlet on the left side of the housing. The steel fixing assembly is mounted on the bottom left side of the housing. A front-to-back lateral movement mechanism and a lifting mechanism are mounted on the right side of the housing. The lifting mechanism is mounted on the front-to-back lateral movement mechanism, and a lifting frame is mounted on the lifting part of the lifting mechanism. A sleeve, a rotating assembly, and a horizontal drive mechanism are mounted on the lifting frame. The sleeve is horizontally positioned on the lifting frame, and both ends of the sleeve are rotatably connected to the lifting frame. The rotating assembly is connected to the sleeve and is used to drive the sleeve to rotate. The shovel is horizontally slidably fitted into the sleeve, with a shovel blade at the left end and the right end of the shovel connected to the horizontal drive mechanism. A blower is positioned downwards above the weld cleaning area inside the housing, and a material discharge port is opened on the frame below the blower. A material receiving box is mounted on the frame below the material discharge port.

[0006] Preferably, the lifting mechanism includes a bracket, a screw, and a vertical rod; the forward and backward lateral movement mechanism includes a slide rail and a third telescopic cylinder installed at the bottom of the housing; the bracket is slidably installed on the slide rail and connected to the piston rod of the third telescopic cylinder; the screw and the vertical rod are vertically installed on the frame; the upper end of the screw is poweredly connected to a first motor on the frame; the lifting frame is threaded onto the screw and slidably mounted on the vertical rod.

[0007] Preferably, the rotating assembly includes a first gear, a second gear, and a second motor. The first gear is coaxially fixed outside the sleeve, the second motor is horizontally mounted on the lifting frame, and the second gear is coaxially mounted on the output shaft of the second motor. The first gear meshes with the second gear.

[0008] Preferably, the horizontal drive mechanism includes a first telescopic cylinder, which is horizontally installed at the right end of the lifting frame, and the right end of the shovel bar is rotatably connected to the piston rod of the first telescopic cylinder.

[0009] Preferably, the steel fixing assembly includes a fixing base and two clamping plates arranged front and rear. The fixing base has two sets of connecting rod assemblies symmetrically arranged in its internal cavity, each connected to a corresponding clamping plate. Each connecting rod assembly includes a first connecting rod, a second connecting rod, a third connecting rod, and a fourth connecting rod. The first and second connecting rods are arranged vertically and parallel, with their lower ends rotatably connected to the inside of the fixing base. The third connecting rod is arranged horizontally, with its two ends rotatably connected to the upper ends of the first and second connecting rods, respectively. A strip-shaped opening is provided at the top of the fixing base in the front-rear direction. The middle part of the clamping plate is slidably engaged in the strip-shaped opening, with its upper end extending through the opening. A vertical groove is provided at the lower end of the clamping plate, and a guide rod fixed in the middle of the third connecting rod is slidably engaged in the groove. The upper end of the fourth connecting rod is rotatably connected to the middle of the second connecting rod, and the other end is inclined downwards. A second telescopic cylinder is vertically positioned between the two sets of connecting rod assemblies, with the lower ends of the fourth connecting rods of both sets rotatably connected to the piston rods of the second telescopic cylinder.

[0010] Preferably, a filter screen is horizontally installed inside the receiving box.

[0011] Preferably, an exhaust vent is provided on the receiving box below the filter screen, and an exhaust fan is installed at the exhaust vent.

[0012] The beneficial effects of this utility model are as follows:

[0013] 1. In this application, when clamping and fixing the steel profile, the piston rod of the second telescopic cylinder moves downward, which in turn pulls the corresponding connecting rod assemblies on both sides to move synchronously through the two fourth connecting rods. This causes the first and second connecting rods of the connecting rod assemblies to swing parallel towards the center, thereby driving the upper third connecting rod to move closer to the center. The guide rod on the third connecting rod moves the clamping plate, causing the two clamping plates to move closer to each other, thereby firmly clamping and fixing the steel profile placed in the center of the fixing seat. This achieves rapid fixing of the steel profile and significantly improves the processing efficiency and the firmness of the steel profile fixing of this device.

[0014] 2. In this application, the third telescopic cylinder can adjust the horizontal position of the support, shovel bar, and other structures in the front-to-back direction. When the first motor drives the screw to rotate, the lifting frame can move up and down under the sliding limit of the vertical rod, thereby driving the shovel bar and other structures on the lifting frame to move up and down, achieving height adjustment, thus significantly improving the convenience of adjusting the horizontal and height of the shovel bar in this device.

[0015] 3. In this application, the angle of the shovel bar is adjusted by using a second motor to drive two gears to rotate, which in turn drives the sleeve and the shovel bar to rotate, thereby achieving the angle adjustment of the shovel bar. This allows the device to adapt to the cleaning operation of welds at different locations. During the shovel bar cleaning operation, the extension action of the piston cylinder of the first telescopic cylinder causes the shovel bar in the sleeve to extend to the left. The shovel blade at the left end of the shovel bar can then be used to clean the weld, significantly improving the efficiency of weld slag removal.

[0016] 4. During operation, with the cooperation of the blower and the exhaust fan, the scraped welding slag and other debris can be blown downwards and collected in the receiving box through the discharge port. The filter screen in the receiving box can effectively filter the impurities and avoid affecting the operation of the exhaust fan. Attached Figure Description

[0018] Figure 2 This is a cross-sectional view of the inner side of the fixing base of this utility model. Detailed Implementation

[0019] The principles and features of this utility model are described below with reference to the accompanying drawings. The examples given are only for explaining this utility model and are not intended to limit the scope of application of this utility model.

[0020] like Figure 1-2As shown, this utility model proposes a steel weld cleaning device, including a frame 1, a shovel 7, and a steel fixing assembly. A box 2 is installed on the top of the frame 1, and a feed inlet 20 is opened on the left side of the box 2. A self-closing curtain is provided at the feed inlet 20 to prevent foreign objects from flying out. The steel fixing assembly is installed on the bottom left side of the box 2. The steel fixing assembly includes a fixing base 3 and two clamping plates 31 arranged front and rear. Two sets of connecting rod assemblies are symmetrically arranged in the cavity inside the fixing base 3, which are respectively connected to the corresponding clamping plates 31. The connecting rod assembly includes a first connecting rod 321, a second connecting rod 322, a third connecting rod 323, and a fourth connecting rod 324. The first connecting rod 321 and the second connecting rod 322 are arranged vertically and parallel. The lower ends of the first connecting rod 321 and the second connecting rod 322 are rotatably connected to the inside of the fixing base 3, respectively. The third connecting rod 323 is arranged horizontally, and its two ends are respectively connected to the upper ends of the first connecting rod 321 and the second connecting rod 322. Rotary connection; the top of the fixed base 3 has a strip-shaped opening 30 in the front-rear direction, the middle part of the clamping plate 31 is slidably locked in the strip-shaped opening 30, the upper end of the clamping plate 31 extends through the strip-shaped opening 30, and the lower end of the clamping plate 31 has a vertically opened sliding groove 310, the horizontally fixed guide rod 33 in the middle of the third connecting rod 323 is slidably locked in the sliding groove 310; the upper end of the fourth connecting rod 324 is rotatably connected to the middle of the second connecting rod 322, and the other end is inclined downward; the second telescopic cylinder 34 is vertically set upward between the two sets of connecting rod assemblies, and the lower ends of the fourth connecting rods 324 of both sets of connecting rod mechanisms are rotatably connected to the piston rod of the second telescopic cylinder 34. The second telescopic cylinder 34 can be a hydraulic cylinder.

[0021] This application describes a method where, during the clamping and fixing of the steel profile, the piston rod of the second telescopic cylinder 34 is driven downward, which in turn pulls the corresponding connecting rod assemblies on both sides to move synchronously through the two fourth connecting rods 324. This causes the first connecting rod 321 and the second connecting rod 322 of the connecting rod assembly to swing parallel towards the center, thereby driving the upper third connecting rod 323 to move closer to the center. The guide rod 33 on the third connecting rod 323 then moves the clamping plate 31, causing the two clamping plates 31 to move closer to each other, thus firmly clamping and fixing the steel profile placed in the center of the fixing seat 3. This achieves rapid fixing of the steel profile and significantly improves the processing efficiency and the firmness of the steel profile fixing of this device.

[0022] The right side of the housing 2 is equipped with a front-to-back lateral movement mechanism and a lifting mechanism. The front-to-back lateral movement mechanism includes a slide rail 4 mounted on the bottom of the housing 2 and a third telescopic cylinder (not shown in the figure). The lifting mechanism has a lifting frame 55 mounted on its lifting part. Specifically, the lifting mechanism includes a bracket 51, a screw 53, and a vertical rod 52. The bracket 51 is slidably mounted on the slide rail 4 and connected to the piston rod of the third telescopic cylinder. The screw 53 and the vertical rod 52 are vertically mounted on the frame 1. The upper end of the screw 53 is powered by the first motor 54 on the frame 1. The lifting frame 55 is threaded onto the screw 53 and slidably mounted on the vertical rod 52.

[0023] In this application, the third telescopic cylinder can adjust the horizontal position of the support 51, the shovel bar 7, and other structures in the front-to-back direction. When the first motor 54 drives the screw 53 to rotate, the lifting frame 55 can move up and down under the sliding limit action of the vertical rod 52, thereby driving the shovel bar 7 and other structures on the lifting frame 55 to move up and down, thereby achieving height adjustment and significantly improving the convenience of adjusting the horizontal and vertical position of the shovel bar 7 in this device.

[0024] A sleeve 551, a rotating assembly, and a horizontal drive mechanism are mounted on the lifting frame 55. The sleeve 551 is horizontally positioned on the lifting frame 55, and its two ends are rotatably connected to the lifting frame. The rotating assembly is connected to the sleeve 551 and is used to drive the sleeve 551 to rotate. The rotating assembly includes a first gear 63, a second gear 62, and a second motor 61. The first gear 63 is coaxially fixed outside the sleeve 551, the second motor 61 is horizontally mounted on the lifting frame 55, and the second gear 62 is coaxially mounted on the output shaft of the second motor 61. The first gear 63 meshes with the second gear 62. The shovel 7 is horizontally slidably fitted into the sleeve 551, and can only slide left and right within the sleeve 551, not rotate. The left end of the shovel 7 has a shovel blade 71, and the right end of the shovel 7 is connected to the horizontal drive mechanism. The horizontal drive mechanism includes a first telescopic cylinder 8, which is horizontally mounted on the right end of the lifting frame 55. The right end of the shovel 7 is rotatably connected to the piston rod of the first telescopic cylinder 8. The first telescopic cylinder 8 can be a hydraulic cylinder structure.

[0025] When adjusting the angle of the scraper 7, the second motor 61 drives two gears to rotate, which in turn drives the sleeve 551 and the scraper 7 to rotate, thereby achieving angle adjustment of the scraper 7. This allows the device to adapt to the cleaning operation of welds at different locations. During the cleaning operation, the extension action of the piston cylinder of the first telescopic cylinder 8 causes the scraper 7 in the sleeve 551 to extend to the left. The scraper blade 71 at the left end of the scraper 7 can then be used to clean the weld, significantly improving the efficiency of weld slag removal.

[0026] A blower 21 is installed above the weld cleaning area inside the housing 2, pointing downwards. An air duct 211 at the blower 21's outlet extends downwards to the weld cleaning area. A material discharge port 10 is provided on the frame 1 below the blower 21, and a receiving box 11 is installed on the frame 1 below the material discharge port 10. A filter screen 13 is horizontally installed inside the receiving box 11. An exhaust port is provided on the receiving box 11 below the filter screen 13, and an exhaust fan 12 is installed at the exhaust port.

[0027] During operation, the blower 21 and the exhaust fan 12 work together to blow the scraped welding slag and other debris downwards and collect them in the receiving box 11 through the discharge port 10. The filter screen 13 in the receiving box 11 can effectively filter the impurities and avoid affecting the operation of the exhaust fan 12.

[0028] When using this utility model, the steel section to be processed is placed on the fixed base 3, and the second telescopic cylinder 34 is driven to move. The fourth connecting rod 324 and the connecting rod assemblies on both sides drive the two clamping plates 31 to move closer to each other, thereby stably clamping and fixing the steel section. Then, the horizontal position, height and angle of the shovel 7 are adjusted by the front and rear horizontal movement mechanism, the lifting mechanism and the rotating assembly. After that, the first telescopic cylinder 8 drives the shovel 7 to move to the left to realize the rapid cleaning operation of the weld.
