Abstract
Description
Technical Field
[0001] This utility model relates to the field of weld cleaning technology, specifically an auxiliary device for cleaning welds of steel box girders. Background Technology
[0002] After welding, steel box girders usually need to have their welds cleaned. This cleaning process is typically done manually with a hand-held grinder. To reduce arm pain from holding the grinder for extended periods, an auxiliary device is used to support the elbows, thus assisting in the weld cleaning process.
[0003] When using the auxiliary device, it needs to be moved to different positions. However, after the auxiliary device is moved by the pulley, the pulley does not have a limiting function, which causes the auxiliary device to move while supporting the user's elbow, resulting in poor performance of the auxiliary device. Utility Model Content
[0004] To address the shortcomings of existing technologies, this utility model provides an auxiliary device for cleaning weld seams of steel box girders, which has advantages such as limiting the pulleys and solving the problem that pulleys do not have a limiting function.
[0005] This utility model discloses an auxiliary device for cleaning weld seams of steel box girders, comprising a base. Support plates are provided on both sides of the top of the base. Support components are provided on the top of corresponding sides of the two support plates. Moving components are provided at the four corners of the bottom of the base. Each moving component includes a fixed rod, the top of which is fixedly connected to the base. A concave plate is provided at the bottom of the fixed rod, and a rotating rod is rotatably connected to the inner cavity of the concave plate. A pulley is fixedly fitted onto the surface of the rotating rod, and a locking hole is formed on the surface of the pulley. Limiting components are provided around the top of the base, each including an electric push rod. The bottom of the electric push rod contacts the base. The output end of the electric push rod extends through and to the bottom of the base, where a first inclined plate is provided. A matching second inclined plate is provided on the inclined surface of the first inclined plate. A locking rod is provided on the outer side of the second inclined plate, and a sliding sleeve is fitted onto the surface of the locking rod. The inner side of the sliding sleeve is connected to the second inclined plate. A spring is installed between the plates, and the spring is sleeved on the surface of the clamping rod. A limiting plate is fixedly sleeved on the outer side of the clamping rod surface. When the auxiliary device moves to the required position and the pulley needs to be limited, the electric push rod operates, which drives the first inclined plate to move downward, the first inclined plate to move the second inclined plate outward, and the inclined plate to move the clamping rod outward. At this time, the clamping rod will move within the sliding sleeve. When the clamping rod moves into the locking hole in the pulley, the pulley can be limited, avoiding the situation where the pulley moves when it does not need to move, thus preventing the auxiliary device from being ineffective. When the pulley needs to move, the electric push rod drives the first inclined plate to reset. At this time, the inertia of the spring drives the second inclined plate to move inward, and the second inclined plate drives the clamping rod to move inward. The limiting plate limits the movement of the sliding rod. When the clamping rod moves out of the locking hole on the pulley, the pulley can be used normally.
[0006] This utility model discloses an auxiliary device for cleaning weld seams of steel box girders. The support assembly includes a sliding rod with both ends in contact with two support plates. Movable sleeves are fitted on both sides of the sliding rod surface. A fixing bolt is fitted at the bottom of each movable sleeve, with one end of the fixing bolt in close contact with the sliding rod. A support seat is fixedly connected to the top of each movable sleeve. When elbow support is needed, the movable sleeve is first moved, allowing it to move stably on the sliding rod surface. This movement drives the support seat to move. Once the support seat is in the desired position, the fixing bolt is rotated. When one end of the fixing bolt is in close contact with the sliding rod, the movable sleeve is fixed to the sliding rod. The user's elbow can then be placed on the support seat.
[0007] The auxiliary device for cleaning weld seams of steel box girders of this utility model has a sliding rod whose two ends are fixedly connected to the two support plates by connecting blocks. The two ends of the sliding rod are located at the center of the top inner side of the two support plates. The connecting blocks can fix the sliding rod, so that the sliding rod is more effective in use and avoids the sliding rod from shaking during use, which would lead to instability of the components on the sliding rod.
[0008] The auxiliary device for cleaning weld seams of steel box girders of this utility model includes a fixing plate fixedly fitted on the surface of the electric push rod, and the inner cavity of the fixing plate is fixedly connected to the base through a fixing component. The fixing plate and the fixing component can fix the electric push rod, thus improving the performance of the electric push rod during use and avoiding shaking of the electric push rod, which would lead to unstable operation of the electric push rod.
[0009] The auxiliary device for cleaning weld seams of steel box girders of this utility model has a limiting plate fixedly fitted on both sides of the sliding sleeve surface, and the top of the limiting plate is fixedly connected to the base. The limiting plate can fix the sliding sleeve, so that the clamping rod moves more stably in the sliding sleeve, avoiding the sliding sleeve from shaking during use, which would lead to the clamping rod moving unstablely in the sliding sleeve.
[0010] The present invention relates to an auxiliary device for cleaning weld seams of steel box girders, wherein the number of clamping holes is six, and the six clamping holes are equally spaced on the surface of the pulley.
[0011] The auxiliary device for cleaning weld seams of steel box girders of this utility model is wherein the two sides of the top of the base are fixedly connected to the support plate by welding, and the two support plates are arranged symmetrically about the base.
[0012] The present invention relates to an auxiliary device for cleaning weld seams of steel box girders, wherein the inner cavity of the support base is provided with a sponge pad, and the bottom of the sponge pad is fixedly connected to the support base by an adhesive.
[0013] The present invention relates to an auxiliary device for cleaning weld seams of steel box girders, wherein the output end of the electric push rod is fixedly connected to the first inclined plate by welding, and the output end of the electric push rod is located at the center of the top of the first inclined plate.
[0014] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0015] 1. When the auxiliary device moves to the required position and the pulley needs to be limited, the electric push rod operates, driving the first inclined plate downwards, which in turn drives the second inclined plate outwards. The inclined plates then drive the locking rod outwards, allowing the locking rod to move within the sliding sleeve. When the locking rod moves into the locking hole inside the pulley, it limits the pulley's movement, preventing it from moving when not needed and thus ensuring the auxiliary device's effectiveness. When the pulley needs to move, the electric push rod resets the first inclined plate. The inertia of the spring then drives the second inclined plate inwards, which in turn drives the locking rod inwards. The limiting plate further limits the movement of the sliding rod. Once the locking rod moves out of the locking hole on the pulley, the pulley can be used normally.
[0016] 2. When the user's elbow needs to be supported, the movable sleeve is moved first. The movable sleeve will move stably on the surface of the slide rod. The movable sleeve drives the support seat to move. After the support seat moves to the position required by the user, the fixing bolt is rotated. When one end of the fixing bolt is in close contact with the slide rod, the movable sleeve can be fixed on the slide rod. At this time, the user's elbow can be placed on the support seat.
[0017] The connecting block can fix the slide bar, which makes the slide bar perform better when used and avoids wobbling during use, thus preventing the components on the slide bar from becoming unstable.
[0018] The limiting plate can fix the sliding sleeve, making the movement of the lever within the sliding sleeve more stable and preventing the sliding sleeve from shaking during use, which would lead to unstable movement of the lever within the sliding sleeve.
[0019] The fixing plate and fasteners can be used to fix the electric linear actuator, which makes the electric linear actuator perform better during use and avoids shaking during use, which would lead to unstable operation of the electric linear actuator. Attached Figure Description

[0026] The following drawings will disclose several embodiments of this utility model. For clarity, many practical details will be described in the following description. However, it should be understood that these practical details should not be used to limit this utility model. That is, in some embodiments of this utility model, these practical details are not essential. In addition, for the sake of simplicity, some conventional structures and components will be shown in the drawings in a simple schematic manner.
[0027] Please see Figure 1-4The auxiliary device for cleaning weld seams of steel box girders of this utility model includes a base 1. Support plates 3 are provided on both sides of the top of the base 1. Support components 4 are provided on the top of corresponding sides of the two support plates 3. Moving components 2 are provided at the four corners of the bottom of the base 1. Each moving component 2 includes a fixed rod 201. The top of the fixed rod 201 is fixedly connected to the base 1. A concave plate 202 is provided at the bottom of the fixed rod 201. A rotating rod 205 is rotatably connected to the inner cavity of the concave plate 202. A pulley 203 is fixedly fitted onto the surface of the rotating rod 205. A locking hole 204 is provided on the surface of the pulley 203. Limiting components 5 are provided around the top of the base 1. Each limiting component 5 includes an electric push rod 501, the bottom of which contacts the base 1. The output end of the electric push rod 501 extends through and to the bottom of the base 1, where a first inclined plate 503 is provided. A matching second inclined plate 504 is provided on the inclined surface of the first inclined plate 503. A locking rod 5010 is provided on the outer side of the second inclined plate 504. A sliding sleeve 508 is fitted on the surface of the locking rod 5010. A spring 505 is provided between the inner side of the sliding sleeve 508 and the second inclined plate 504, and the spring 505 is fitted onto the locking rod 501. On the surface of 0, a limiting disc 509 is fixedly sleeved on the outer side of the surface of the locking rod 5010. When the auxiliary device moves to the required position and needs to limit the pulley 203, the electric push rod 501 operates, driving the first inclined plate 503 downward, which in turn drives the second inclined plate 504 outward, which in turn drives the locking rod 5010 outward. At this time, the locking rod 5010 will move within the sliding sleeve 508. When the locking rod 5010 moves to the locking hole 204 in the pulley 203, the pulley 203 can be limited. 03 is used to limit the movement of pulley 203 when it is not needed, which would lead to poor performance of the auxiliary device. When pulley 203 needs to move, electric push rod 501 drives the first inclined plate 503 to reset. At this time, the inertia of spring 505 drives the second inclined plate 504 to move inward. The second inclined plate 504 drives the locking rod 5010 to move inward. The limiting plate 509 limits the movement of sliding rod 405. When the locking rod 5010 moves out of the locking hole 204 on pulley 203, pulley 203 can be used normally.
[0028] The support assembly 4 includes a slide rod 405, with both ends of the slide rod 405 contacting two support plates 3. Movable sleeves 404 are fitted on both sides of the surface of the slide rod 405. A fixing bolt 403 is fitted at the bottom of the movable sleeve 404, with one end of the fixing bolt 403 in close contact with the slide rod 405. A support seat 401 is fixedly connected to the top of the movable sleeve 404. When the user's elbow needs support, the movable sleeve 404 is first moved, allowing it to move stably on the surface of the slide rod 405. This movement of the movable sleeve 404 drives the support seat 401 to move. After the support seat 401 moves to the desired position, the fixing bolt 403 is rotated. When one end of the fixing bolt 403 is in close contact with the slide rod 405, the movable sleeve 404 is fixed to the slide rod 405. At this point, the user's elbow can be placed on the support seat 401.
[0029] Both ends of the slide rod 405 are fixedly connected to the two support plates 3 by connecting blocks 402. The two ends of the slide rod 405 are located at the center of the top inner side of the two support plates 3. The connecting blocks 402 can fix the slide rod 405, so that the slide rod 405 performs better when in use and avoids the slide rod 405 from shaking during use, which would lead to the instability of the components on the slide rod 405.
[0030] The surface of the electric push rod 501 is fixedly fitted with a fixing plate 506, and the inner cavity of the fixing plate 506 is fixedly connected to the base 1 through a fixing member 502. The fixing plate 506 and the fixing member 502 can fix the electric push rod 501, so that the electric push rod 501 performs better when used and avoids the electric push rod 501 shaking during use, which would lead to the unstable operation of the electric push rod 501.
[0031] Limiting plates 507 are fixedly fitted on both sides of the surface of the sliding sleeve 508, and the top of the limiting plate 507 is fixedly connected to the base 1. The limiting plate 507 can fix the sliding sleeve 508, so that the locking rod 5010 moves more stably in the sliding sleeve 508, avoiding the sliding sleeve 508 from shaking during use, which would lead to the locking rod 5010 moving unstablely in the sliding sleeve 508.
[0032] There are six locking holes 204, and the six locking holes 204 are equally spaced on the surface of the pulley 203.
[0033] The two sides of the top of the base 1 are fixedly connected to the support plate 3 by welding, and the two support plates 3 are arranged symmetrically about the base 1.
[0034] The inner cavity of the support base 401 is provided with a sponge pad, and the bottom of the sponge pad is fixedly connected to the support base 401 by an adhesive.
[0035] The output end of the electric push rod 501 is fixedly connected to the first inclined plate 503 by welding, and the output end of the electric push rod 501 is located at the center of the top of the first inclined plate 503.
[0036] When using this utility model: when the auxiliary device moves to the required position and needs to limit the pulley 203, the electric push rod 501 operates, driving the first inclined plate 503 downward, which in turn drives the second inclined plate 504 outward, which in turn drives the locking rod 5010 outward. The locking rod 5010 then moves within the sliding sleeve 508. When the locking rod 5010 reaches the locking hole 204 within the pulley 203, the pulley 203 is limited, preventing the pulley from... If pulley 203 moves when it is not needed, it will lead to poor performance of the auxiliary device. When the pulley 203 needs to move, the electric push rod 501 drives the first inclined plate 503 to reset. At this time, the inertia of the spring 505 drives the second inclined plate 504 to move inward. The second inclined plate 504 drives the locking rod 5010 to move inward. The limiting plate 509 limits the movement of the sliding rod 405. When the locking rod 5010 moves out of the locking hole 204 on the pulley 203, the pulley 203 can be used normally.
[0037] The above are merely embodiments of this utility model and are not intended to limit the scope of this utility model. Various modifications and variations can be made to this utility model by those skilled in the art.
