Abstract
Description
Technical Field
[0001] This utility model relates to the field of crane technology, and specifically to a crane outrigger stabilization and reinforcement structure. Background Technology
[0002] Cranes play an indispensable role as key material handling equipment in many fields such as modern industrial production, construction, and logistics. With the continuous expansion of project scale and the increasing complexity of operational requirements, the demands on crane performance, especially outrigger stability, are becoming increasingly stringent.
[0003] According to the public announcement (CN219031598U), a crane outrigger structure is disclosed. This technology discloses a structure that includes a connecting rod and a cylinder fixedly mounted on the connecting rod. When the crane is moved to a suitable position, the connecting rod extends the cylinder to the support point, activating the cylinder. This causes the support leg plate to contact the ground, at which point the compression unit on the support leg plate is compressed. The compression unit drives the tilting rod to slide along the corresponding movable chamber, and the tilting rod compresses the trapezoidal block. The trapezoidal block slides horizontally along the movable chamber, and during its movement, it compresses the push rod. The push rod then drives the support panel to slide along the connecting groove, at which point four support panels extend from the support leg plate. This technical solution increases the contact area between the support leg plate and the ground, further ensuring the stability of the crane.
[0004] In the aforementioned comparative documents, the compression unit is used to compress the tilting rod and trapezoidal block to push the support panel, thereby increasing the contact area between the support leg plate and the ground. However, when the compression unit compresses the tilting rod and trapezoidal block, the springs installed on the outrigger structure are also compressed. Cranes are generally used for long wind protection, so the springs will be compressed for a long time, which may lead to damage and affect subsequent use. At the same time, when the support panel is pushed, it is generally close to the ground. If unevenness is avoided, the support panel may be blocked by the ground when moving, resulting in jamming and affecting the support of the crane.
[0005] To address the aforementioned issues, this application proposes a crane outrigger stabilization and reinforcement structure. Utility Model Content
[0006] This utility model addresses the technical problems existing in the prior art by providing a crane outrigger stabilization and reinforcement structure.
[0007] The technical solution of this utility model to solve the above-mentioned technical problems is as follows: a crane outrigger stabilization and reinforcement structure, including a connecting plate, a flip plate is provided at one end of the connecting plate, and an outrigger assembly is provided on the flip plate;
[0008] The outrigger assembly includes a cylinder fixedly connected to the top of the flip plate, a circular block fixedly connected to the telescopic end of the cylinder, a connecting rod fixedly connected to the bottom of the circular block, a circular plate fixedly connected to the bottom of the connecting rod, a circular tube slidably connected to the outer wall of the circular plate, a base provided at the bottom of the circular tube, a sliding groove provided at the bottom of the base, a sliding plate slidably connected to the base through the sliding groove, a hinge block fixedly connected to the top of the sliding plate, a linkage rod hinged to the hinge block, the top of the linkage rod hinged to the outer wall of the circular block, and a limit assembly provided at the bottom of the flip plate.
[0009] The limiting component includes a limiting block fixedly connected to the outer wall of the round tube, a fixing plate fixedly connected to the bottom of the flip plate, a fixing frame fixedly connected to the bottom of the fixing plate, a spring fixedly connected to the inner wall of the fixing frame, a telescopic block fixedly connected to one end of the spring, and the telescopic block slidably connected to the fixing frame. By setting the limiting component, the round tube is limited, thus avoiding affecting the use of the round tube and the base.
[0010] The base is rotatably connected to a ball via a sliding groove. The outer wall of the ball is in contact with the side wall of the sliding plate. By setting the ball, the friction at the contact point between the sliding plate and the base is reduced, thus avoiding affecting the support of the crane.
[0011] A scraper is fixedly connected to the outer wall of the base. One side of the scraper is in contact with the outer wall of the sliding plate. By setting the scraper, the surface of the sliding plate can be cleaned, so as to avoid affecting the movement of the sliding plate during storage.
[0012] The bottom of the circular tube is provided with a bolt, and the bottom of the bolt is threaded to the base. By providing the bolt, the base can be replaced, thus avoiding affecting the support of the crane.
[0013] An electric push rod is hinged to the top of the connecting plate. The telescopic end of the electric push rod is hinged to the top of the tilting plate. An opening is provided on the connecting plate. By setting the electric push rod and the opening, the tilting plate can be adjusted to avoid the slope affecting the use of the crane.
[0014] A rubber pad is fixedly connected to the inner wall of the circular tube. By setting the rubber pad, the circular plate is protected and prevented from being damaged by compression when it is squeezed against the inner wall of the circular tube.
[0015] The beneficial effects of this utility model are:
[0016] When the crane needs to use outriggers, the cylinder can push the circular block. The movement of the circular block will drive the sliding plate to move through the circular plate and linkage rod, thereby increasing the contact range between the outrigger and the ground. As the circular block continues to move, it will push the circular tube through the connecting rod and circular plate, thereby causing the base to move down and contact the ground, thus achieving stable support for the crane.
[0017] By setting a limiting component, the circular tube is limited. When the connecting rod initially moves, the limiting block can be blocked by the telescopic block to prevent the circular tube from moving when the connecting rod initially slides down, thus avoiding affecting the rotation of the linkage rod. After the connecting rod moves a certain distance, the telescopic block will slide into the inside of the fixed frame under the action of the spring, thus avoiding affecting the use of the circular tube and the base.

[0038] Working principle:
[0039] The crane outrigger stabilization and reinforcement structure allows for the activation of cylinder 301 when the crane needs to use the outriggers. The telescopic end of cylinder 301 pushes the circular block 302. When the circular block 302 initially moves the connecting rod 303, the telescopic block 405 blocks the limiting block 401, preventing the circular tube 305 from moving during the initial sliding of the connecting rod 303. This avoids affecting the rotation of the linkage rod 307. The movement of the circular block 302 then drives the sliding plate 309 to move through the circular plate 304 and the linkage rod 307, increasing the contact range between the outriggers and the ground. As the circular block 302 continues to move, the telescopic block 405 slides into the fixed frame 403 under the action of the spring 404, preventing interference with the use of the circular tube 305 and the base 306. The circular block 302 then pushes the circular tube 305 through the connecting rod 303 and the circular plate 304, causing the base 306 to move down and contact the ground, thus achieving stable support for the crane.
