[0044] The accompanying drawings illustrate specific embodiments of this application, which will be described in more detail below. These drawings and descriptions are not intended to limit the scope of the concept in any way, but rather to illustrate the concept of this application to those skilled in the art through reference to particular embodiments. Detailed Implementation
[0045] As described in the background section, in heavy machinery, the boom usually serves as a mechanical arm to lift and move objects. Before assembly and use, the boom usually needs to be pre-machined with some holes and grooves to facilitate its installation on the machinery and its connection with other mechanical components.
[0046] Currently, booms are mainly clamped manually using mechanical clamps. For example, operators use bolts, pins, or other mechanical connectors to fix the boom in a specific position. In other words, the automation level of boom clamping is currently low, resulting in high labor costs.
[0047] To address the aforementioned technical problems, this application provides a boom clamp. Under the control of a controller, a magnetic attraction mechanism on the worktable effectively adsorbs and positions the boom. Simultaneously, a driving component drives clamping mechanisms on both sides of the worktable, using a first pressing member to clamp the boom and fix it along its length, achieving rapid clamping under electrical control. Furthermore, the clamping mechanism uses a hydraulic drive unit to drive a first lifting module to adjust the height of the first pressing member, adapting to booms of different sizes. Thus, compared to manual operation of mechanical equipment for boom clamping, the clamp provided in this application significantly reduces boom clamping time and the labor intensity of workers, facilitating subsequent machining, troubleshooting, and maintenance of the boom.
[0048] To make the above-mentioned objectives, features, and advantages of the embodiments of this application more apparent and understandable, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.
[0049] The boom clamp provided in this application embodiment is used to clamp a boom, wherein the boom can be the boom of heavy machinery, such as concrete pump trucks, cranes, excavators, drilling rigs, etc. For example, the boom can be a straight boom, a folding boom, or a multi-section boom, etc.
[0050] refer to Figures 1 to 3 The boom clamp provided in this application includes a worktable 100, at least two clamping mechanisms 200, and a magnetic attraction mechanism 300. The two clamping mechanisms 200 are spaced apart on the worktable 100. Each clamping mechanism 200 includes a base 210, a hydraulic drive unit, a first lifting module 220, and a first pressing member 230. The base 210 is slidably connected to the worktable 100. The hydraulic drive unit drives and connects to the first lifting module 220. The first lifting module 220 is disposed on the base 210. The first pressing member 230 is connected to the first lifting module 220. The suction mechanism 300 includes a sliding seat 310 and a magnetic suction member 320. The sliding seat 310 is slidably connected to the worktable 100, and the magnetic suction member 320 is fixed on the sliding seat 310. The magnetic suction member 320 is used to magnetically suction the boom. The clamp also includes a drive member and a controller. The drive member is connected to the base 210 and the sliding seat 310. The controller is fixed relative to the worktable 100, and the controller is signal-connected to the hydraulic drive unit and the drive member to control the drive member to drive the two bases 210 to move closer to the boom located on the worktable 100, so that the first pressing member 230 abuts against the boom.
[0051] With this configuration, under the control of the controller, the magnetic suction mechanism 300 on the worktable 100 can effectively attract and position the boom. At the same time, the driving component drives the clamping mechanism 200 on both sides of the worktable 100, and the first pressing component 230 of the mechanism clamps the boom, fixing the boom in the length direction, thus achieving rapid clamping under electrical control.
[0052] Furthermore, the clamping mechanism 200 uses a hydraulic drive unit to drive the first lifting module 220 to adjust the height of the first pressing piece 230, which can also be adapted to booms of different sizes. In this way, compared with manual operation of mechanical equipment to clamp the boom, the clamping time of the boom provided by this application can be greatly reduced, and the labor intensity of the workers can be greatly reduced, which facilitates the subsequent machining, troubleshooting or maintenance of the boom.
[0053] In this embodiment, for example, the controller may include a PLC controller, and the hydraulic drive unit includes a hydraulic station, multiple pressure sensors, and hydraulic pipelines. The hydraulic station is connected to the first lifting module 220 via hydraulic pipelines. The controller has a human-machine interface, allowing personnel to quickly set the actions of each unit through click-based programming, thereby controlling the actions of the hydraulic drive unit and drive components.
[0054] In some embodiments, the first pressing member 230 includes a pressing block 231, which is installed on the first lifting module 220 and can be driven by the first lifting module 220 to move up and down in the vertical direction. Furthermore, the pressing surface of the pressing block 231 is a plane or an arc surface, which can adapt to booms with different sidewall shapes.
[0055] For example, the pressure block 231 is provided with a first screw hole, the first lifting module 220 includes a lifting unit, the lifting unit is provided with a second screw hole, and the pressure block 231 is fixed to the lifting unit by a threaded connector passing through the first screw hole and the second screw hole, thus ensuring the working stability of the pressure block 231.
[0056] In some embodiments, the first pressing member 230 further includes a first pressing arm 232, which is tractively connected to the first lifting module 220. The first pressing arm 232 has a first pressing head facing the worktable 100. Further, the first pressing head can be an elastic roller, such as a nylon wheel, which can improve the tightness of the first pressing arm 232 in pressing the boom. Compared with a flat-head pressing arm, the sliding friction is changed to rolling friction when pressing the boom, for example, protecting the surface structure of the boom.
[0057] In some embodiments, the first lifting module 220 includes a first lifting seat 221 and a first lifting frame 222. The first lifting frame 222 is slidably connected to the first lifting seat 221 and is drively connected to a hydraulic drive unit. There are at least two first pressure arms 232. Along the width direction of the worktable 100, two first pressure arms 232 are spaced apart and connected to the first lifting frame 222. For example, there are two first pressure arms 232 or three first pressure arms 232.
[0058] In some embodiments, the first pressing member 230 further includes a second pressing arm 233, which is rotatably connected to the base 210. For example, the base 210 is provided with a rotating seat, and the rotating seat is provided with a rotating unit. The second pressing arm 233 is throttle connected to the rotating unit, and the rotating unit is signal connected to the controller.
[0059] In this way, the controller can control the rotating unit to drive the second pressure arm 233 to rotate, so as to adjust the different angles of the second pressure arm 233 to adapt to the boom with different contour shapes. The setting of the second pressure arm 233 further strengthens the clamping force on the side of the boom.
[0060] In some embodiments, a clamping mechanism 400 is also included, which includes at least two clamping members 410. Along the width direction of the worktable 100, the two clamping members 410 are spaced apart on the sliding seat 310. The clamping members 410 are throttle connected to the driving member so as to be driven by the driving member to move relative to the sliding seat 310 to clamp the arm.
[0061] For example, the clamping member 410 is a clamping bracket, which is erected on the sliding seat 310. A slide rail is installed on the sliding seat 310 and extends along the width direction of the platform. The clamping bracket is slidably connected to the slide rail and is signal-connected to the controller. In this way, after the boom is placed on the workbench 100, the operator can electrically control the clamping bracket to clamp the boom on both sides along the width direction of the boom to improve the clamping force on the boom.
[0062] In some embodiments, there are at least two clamping mechanisms 400, and the two clamping mechanisms 400 are spaced apart along the length direction of the worktable 100. For example, there are two clamping mechanisms 400.
[0063] In more examples, four clamping mechanisms 400 are provided, two of which are configured to clamp the middle of the boom, and the other two are used to clamp the sidewalls of the boom near the end, to further accommodate the clamping of longer booms.
[0064] In some embodiments, the clamping mechanism 200 further includes a second lifting module 240 and a second pressing member 250. The second lifting module 240 is disposed on the sliding seat 310 and is driven to the hydraulic drive unit so as to be driven by the hydraulic drive unit to move relative to the sliding seat 310. The second pressing member 250 is driven to the second lifting module 240 so as to press against the top surface of the boom. In this way, it can cooperate with the magnetic suction mechanism 300 to achieve a bidirectional clamping function along the boom height direction.
[0065] In some embodiments, the magnetic chuck 320 is a magnetic chuck, which is fixed to the sliding seat 310. The magnetic chuck's magnetic surface faces away from the worktable 100 to magnetically attract the bottom surface of the arm.
[0066] In some embodiments, the worktable 100 includes a base and a linear guide. The linear guide is mounted on the base, and the base 210 and the sliding seat 310 are slidably connected to the linear guide. A driving member drives the base 210 and the sliding seat 310 to slide along the linear guide.
[0067] Furthermore, the worktable 100 also includes a rack, which is fixedly connected to the linear guide. The driving component is a drive motor, and a transmission gear is connected to the output shaft of the drive motor. The transmission gear meshes with the rack, and the drive motor is connected to the base 210 and the sliding seat 310 through a transmission rod.
[0068] For example, a drive motor is provided under each base 210 and each slide seat 310. In this way, the rotation of the output shaft of the drive motor is converted into linear kinetic energy to drive the base 210 and slide seat 310 to move relative to the worktable 100 through the cooperation of gears and racks.
