Description

Technical Field

[0001] This utility model relates to the field of crane technology, and in particular to a crane side anti-slip outrigger device. Background Technology

[0002] Crane side anti-slip outriggers are suitable for a variety of complex working conditions. In the construction field, when facing muddy and soft foundations or sloping ground, they can prevent the crane from slipping and overturning during lifting operations. In bridge construction, they can ensure equipment stability when working on narrow bridge surfaces with uneven loads. In municipal engineering emergency repairs, they can quickly stabilize the crane body when dealing with slippery roads caused by sudden severe weather.

[0003] In existing technologies, some crane side anti-slip outrigger devices prevent lateral slippage by increasing friction and providing stable support. The device includes retractable outriggers and anti-slip pads. During operation, the outriggers extend and land vertically, and the pads contact the ground to increase the force-bearing area. The bottom surface of the pads is designed with a serrated, textured, or rubber material to increase the coefficient of friction with the ground.

[0004] However, in actual use, when a crane is lifting heavy objects, the center of gravity will shift to one side of the boom. The side anti-slip outriggers need to balance this torque through grip. If the grip is insufficient, the outriggers may slide on the ground, causing the crane to lose balance or even tip over. In response to the above problems, a crane side anti-slip outrigger device is proposed. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a crane side anti-slip outrigger device, which aims to improve the problem that some existing crane side anti-slip outrigger devices cannot increase grip.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A crane side anti-slip outrigger device includes a mounting frame and a mounting chassis. Extension brackets are fixedly connected to the left and right sides of the mounting frame. A hydraulic cylinder is fixedly connected inside the extension bracket. A drive rod is fixedly connected to the drive end of the hydraulic cylinder. A grip enhancement mechanism is slidably connected to the outside of the drive rod. A disassembly and assembly mechanism is slidably connected to the front and rear sides of the extension bracket.

[0008] The grip enhancement mechanism includes a sliding mounting ring, which is slidably connected to the outside of the drive rod. Multiple mounting brackets are fixedly connected to the outside of the sliding mounting ring. A rotating plate is rotatably connected to the outside of the mounting brackets. A sliding plate is rotatably connected to the bottom of the rotating plate. Multiple extension frames are fixedly connected to the outside of the mounting chassis. Limiting components are provided on the outside of the extension frames. A sliding rod is fixedly connected to the outside of the sliding plate. An anti-slip rubber pad is fixedly connected to the bottom of the sliding rod. A clamping component is fixedly connected to the top of the sliding mounting ring.

[0009] As a further description of the above technical solution:

[0010] The limiting component includes a slide groove, the exterior of which is formed on the exterior of the extension frame, and a connecting shaft is slidably connected inside the slide groove.

[0011] As a further description of the above technical solution:

[0012] The clamping assembly includes a locking plate, the locking plate is fixedly connected to the top of the sliding mounting ring, and a locking rod is slidably connected to the outside of the locking plate. The outside of the locking rod is clamped to the outside of the slot of the drive rod.

[0013] As a further description of the above technical solution:

[0014] The connecting shaft is externally fixedly connected to the inside of the sliding plate, and the connecting shaft is externally slidably connected to the inside of the extension frame.

[0015] As a further description of the above technical solution:

[0016] The disassembly and assembly mechanism includes a sliding latch, which is slidably connected to the outside of the extension bracket. The extension bracket has a cavity inside. A pull plate is fixedly connected to the outside of the sliding latch. A limit plate is slidably connected inside the cavity. A return spring is sleeved on the outside of the sliding latch. A limit latch is slidably connected to the top of the extension bracket. The outside of the limit latch is locked to the outside of the sliding latch.

[0017] As a further description of the above technical solution:

[0018] The bottom of the drive rod is rotatably connected to a connecting mounting cylinder, the top outer end of the mounting chassis is fixedly connected to the top outer end of the connecting mounting cylinder, and the bottom outer end of the mounting chassis is fixedly connected to a mounting pad.

[0019] As a further description of the above technical solution:

[0020] The inside of the limiting plate is fixedly connected to the outside of the sliding clamp, and the outside of the sliding clamp is locked to the outside of the hydraulic cylinder;

[0021] As a further description of the above technical solution:

[0022] One end of the reset spring is fixedly connected to the outside of the limiting plate, and the other end of the reset spring is fixedly connected to the inside of the cavity.

[0023] This utility model has the following beneficial effects:

[0024] 1. In this utility model, the rotating plate can drive the connecting shaft to slide inside the slide groove through the sliding plate, which in turn allows the sliding plate to drive the sliding rod to slide inside the extension frame. This allows the sliding rod to open or close the anti-slip rubber pad. When adjusted to a suitable position, the locking rod outside the locking plate is released, causing the locking rod to engage with the outer slot of the drive rod. This increases the unfolded area of ​​the anti-slip rubber pad, thereby making the overall support more stable.

[0025] 2. In this utility model, when installing the hydraulic cylinder, the hydraulic cylinder is placed in the through hole of the extension bracket. At this time, by releasing the pull plate, the return spring rebounds, which in turn locks the sliding rod with the outside of the hydraulic cylinder. Then, by inserting the limit rod, the limit rod is locked with the sliding rod, thus realizing the installation of the hydraulic cylinder. Because of the limit plate, the sliding rod will not disengage from the inside of the extension bracket when it rebounds. Attached Figure Description

[0032] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0033] Reference Figures 1 to 3 This utility model provides an embodiment of a crane side anti-slip outrigger device, including a mounting frame 1 and a mounting chassis 6. The mounting frame 1 serves as the basic support structure for the entire anti-slip outrigger device, connecting the crane body to other components and evenly transferring the weight and lateral force of the crane during operation to the ground, ensuring stable operation of the device. Extension brackets 2 are fixedly connected to the left and right sides of the mounting frame 1. The extension brackets 2 connect the mounting frame 1 to the grip enhancement mechanism, and under the drive of a hydraulic cylinder 3, extend or retract the grip enhancement mechanism. They also provide installation positions for the disassembly and assembly mechanism, ensuring orderly and coordinated operation of all components. A hydraulic cylinder 3 is fixedly connected inside the extension bracket 2. During crane operation, the hydraulic cylinder 3... The hydraulic system provides power to push the drive rod 4 to extend, so that the grip enhancement mechanism contacts the ground and applies pressure to achieve the anti-slip function of the outrigger. After the operation is completed, the drive rod 4 is retracted to facilitate the movement and storage of the device. The drive end of the hydraulic cylinder 3 is fixedly connected to the drive rod 4, and the grip enhancement mechanism is slidably connected to the outside of the drive rod 4. The front and rear sides of the extension bracket 2 are slidably connected to the disassembly and assembly mechanism. The disassembly and assembly mechanism includes a sliding latch 18. When installing or disassembling the grip enhancement mechanism and other components, the sliding latch 18 is slidably moved in the guide groove by pulling the pull plate 19 to achieve quick disassembly and assembly of the components. This ensures that the components are not easy to rust in complex outdoor environments and maintain good performance for a long time. The sliding latch 18 is slidably connected to the outside of the extension bracket 2.

[0034] The extension bracket 2 has an internal cavity 20, which provides installation space and motion guidance for the sliding lever 18, the limiting plate 21, and the return spring 22. It is a key structural element for the disassembly and assembly mechanism, ensuring the stability and reliability of the coordinated operation of all components. The sliding lever 18 is externally fixedly connected to a pull plate 19, which provides a force application point for the operator. By pulling the pull plate 19, the sliding of the sliding lever 18 can be easily controlled, enabling rapid operation of the disassembly and assembly mechanism and improving the maintenance and usage efficiency of the device. The limiting plate 21 is slidably connected inside the cavity 20. The limiting plate 21 slides within the cavity 20, limiting the sliding stroke of the sliding lever 18 to prevent it from sliding out of the cavity 20. It also provides stable support during the sliding process, ensuring the accurate movement of the sliding lever. To enhance reliability of disassembly and assembly operations, a return spring 22 is fitted around the sliding lever 18. When the sliding lever 18 is pulled, the return spring is compressed. After the pull plate 19 is released, the return spring releases energy, pushing the limit plate 21 and the sliding lever 18 back to their initial state, facilitating the next operation and achieving an automatic reset function, thus improving ease of use. A limit lever 23 is slidably connected to the outer top of the extension bracket 2. When the sliding lever 18 slides into place, the limit lever is inserted, causing its wedge-shaped head to engage with the slot of the sliding lever 18, thus fixing the sliding lever 18 and preventing it from loosening due to vibration or other factors during crane operation. This ensures that all components of the device are securely connected, improving the safety of the device. The outer side of the limit lever 23 is engaged with the outer side of the sliding lever 18.

[0035] The grip enhancement mechanism includes a sliding mounting ring 8, which converts the axial movement of the drive rod 4 into the swing of the rotating plate 10, while providing a mounting base for the mounting bracket 9 to ensure the stability and synchronization of the grip assembly. The sliding mounting ring 8 is internally slidably connected to the outside of the drive rod 4, and multiple mounting brackets 9 are fixedly connected to the outside of the sliding mounting ring 8. These brackets transmit the thrust of the drive rod 4 to the rotating plate 10 and also serve as a support shaft for the rotating plate 10, guiding its swing direction and ensuring the accuracy of the gripping action. The rotating plate 10 is rotatably connected to the outside of the mounting bracket 9, swinging around its axis under the drive of the mounting bracket 9, thus enhancing the gripping action. The horizontal movement of the moving mounting ring 8 is converted into the vertical downward pressing action of the sliding plate 11, so as to achieve a tight fit between the anti-slip rubber pad 16 and the ground and enhance the grip. The outer bottom end of the rotating plate 10 is rotatably connected to the sliding plate 11, which slides vertically along the slide groove 13 under the drive of the rotating plate 10, and transmits mechanical force to the anti-slip rubber pad 16. Multiple extension frames 12 are fixedly connected to the outside of the mounting chassis 6 to provide vertical guide rails for the sliding plate 11 and the sliding rod 15, restrict their lateral displacement, and ensure that the gripping action is accurately executed in the vertical direction. Limiting components are opened on the outside of the extension frame 12.

[0036] The limiting component includes a slide groove 13, which is externally formed on the exterior of the extension frame 12. A connecting shaft 14 is slidably connected inside the slide groove 13. The connecting shaft 14 connects the sliding plate 11 and the sliding rod 15, transmitting vertical thrust and pull forces. It also acts as a limiting component, preventing the sliding rod 15 from disengaging from the slide groove 13 and ensuring the motion accuracy of the grip enhancement mechanism. The sliding rod 15 is fixedly connected to the exterior of the sliding plate 11, transmitting the mechanical force of the sliding plate 11 to the anti-slip rubber pad 16. Simultaneously, the rod slides along the slide groove 13, ensuring the pad is pressed vertically downwards and preventing uneven grip caused by tilting. The bottom of the sliding rod 15 is fixedly connected to the anti-slip rubber pad 16, directly contacting the ground. Its high elasticity and high friction characteristics increase the grip of the outriggers. The sliding mounting ring 8 has good adhesion to the ground and also cushions the vibration during crane operation to prevent ground damage. The top of the sliding mounting ring 8 is fixedly connected to a clamping assembly, which includes a locking plate 17. The clamping assembly provides a sliding track for the clamping rod, ensuring that the clamping rod is accurately engaged in the slot of the drive rod 4, thereby locking the position of the sliding mounting ring 8 and preventing displacement caused by vibration during operation. The locking plate 17 is externally fixedly connected to the top of the sliding mounting ring 8, and the clamping rod is slidably connected to the outside of the locking plate 17. After being inserted into the slot of the drive rod 4, the sliding mounting ring 8 is fixed in the designated position by the wedge structure and spring preload, bearing the lateral force during crane operation and ensuring the reliability of the grip enhancement mechanism. The outside of the clamping rod is clamped to the outside slot of the drive rod 4.

[0037] Reference Figures 2 to 4 The connecting shaft 14 is externally fixedly connected to the inside of the sliding plate 11, and externally slidably connected to the inside of the extension frame 12. The bottom of the drive rod 4 is rotatably connected to the connecting mounting cylinder 5, which can withstand large radial and axial loads while allowing a certain angular deviation to ensure the stability of the drive rod 4 during rotation. The top of the mounting base 6 is fixedly connected to the top of the connecting mounting cylinder 5, and the bottom of the mounting base 6 is fixedly connected to the mounting pad 7. The four corners of the pad have through holes corresponding to the mounting holes on the mounting base 6, for mounting the pad with anchor bolts. The plate and chassis are fixed to the ground together. The inside of the limiting plate 21 is fixedly connected to the outside of the sliding rod 18. The outside of the sliding rod 18 is locked to the outside of the hydraulic cylinder 3. One end of the return spring 22 is fixedly connected to the outside of the limiting plate 21, and the other end of the return spring 22 is fixedly connected to the inside of the cavity 20. When it is necessary to disassemble or replace the hydraulic cylinder 3, pull the pull plate 19 to pull the sliding rod 18 out of the slot. At this time, the return spring 22 is compressed. After the operation is completed, release the pull plate 19, and the return spring 22 releases its elastic potential energy, pushing the sliding rod 18 back to the initial position for easy use next time.

[0038] Working principle: When improving the grip of the anti-slip rubber pad 16, the locking bar on the outside of the locking plate 17 is pressed, causing the locking bar to separate from the slot on the outside of the drive rod 4. This allows the sliding mounting ring 8 to slide outside the drive rod 4, and the outer rotating plate 10 of the sliding mounting ring 8 to rotate inside the mounting frame 9. Under the rotation of the rotating plate 10, the rotating plate 10 can drive the connecting shaft 14 to slide inside the slide groove 13 via the sliding plate 11. This allows the sliding plate 11 to drive the sliding rod 15 to slide inside the extension frame 12, allowing the sliding rod 15 to open or close the anti-slip rubber pad 16. When adjusted to the appropriate position, the locking bar on the outside of the locking plate 17 is released, causing the locking bar to lock into the slot on the outside of the drive rod 4. This increases the unfolded area of ​​the anti-slip rubber pad 16, making the overall support more stable.

[0039] When disassembling and assembling the hydraulic cylinder 3, pulling the limiting rod 23 separates it from the sliding rod 18, releasing the sliding rod 18 from its locked state. Pulling the pull plate 19 then allows it to slide the limiting plate 21 inside the cavity 20 via the sliding rod 18. This causes the limiting plate 21 to compress the return spring 22, deforming it and separating the sliding rod 18 from the outside of the hydraulic cylinder 3. The hydraulic cylinder 3 can then be removed for inspection. When installing the hydraulic cylinder 3, by placing the hydraulic cylinder 3 in the through hole of the extension bracket 2, the pull plate 19 is released, causing the return spring 22 to rebound, which in turn allows the sliding latch 18 to be locked to the outside of the hydraulic cylinder 3. At this time, by inserting the limit latch 23, the limit latch 23 is locked to the sliding latch 18, thus enabling the installation of the hydraulic cylinder 3. Because of the limit plate 21, the sliding latch 18 will not disengage from the inside of the extension bracket 2 when it rebounds.

[0040] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
