Description

Technical Field

[0001] This utility model relates to the field of tower crane support structures, and in particular to a tower crane attachment rod connection structure. Background Technology

[0002] A search of Chinese patents revealed publication number CN212450366U, which discloses an easy-to-install tower crane attachment rod connection structure. This structure includes an attachment rod body and a fixing plate. The fixing plate is mounted on the outer wall of the attachment rod body, and the side wall of the fixing plate closest to the attachment rod body is welded to the attachment rod body via a connecting rod. This invention utilizes a rotating turntable to drive a screw rod, thereby fine-tuning the position of a right-angle plate. This ensures that the screw rod within the connecting hole aligns with the mounting hole of the frame beam, facilitating quick and easy installation and improving the efficiency and accuracy of the attachment rod installation.

[0003] Existing anchor rod connection structures cannot adjust the angle; generally, they can only adjust the length, not the angle. During installation, if there is a misalignment between the tower crane anchor rod and the connection structure, installation becomes difficult, requiring disassembly and adjustment of the connection structure before reinstallation—a cumbersome process that increases workload, reduces efficiency, and hinders assembly and disassembly of the tower crane anchor rod. Typically, the connection structure is fixed to the tower crane anchor rod with multiple bolts, requiring tools for disassembly and assembly, which is also tedious, increasing workload and reducing efficiency. To address these problems, we propose a new tower crane anchor rod connection structure. Utility Model Content

[0004] The purpose of this utility model is to provide a tower crane attachment rod connection structure, which has the advantages of adjustable angle and easy assembly and disassembly of the tower crane attachment rod.

[0005] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a tower crane attachment rod connection structure, including a base plate, a fixing block bolted to the top of the base plate, a ball rollingly connected to the inner wall of the fixing block, a pressure plate slidably connected to the inner wall of the fixing block, a fixing bolt rotatably connected to the surface of the pressure plate, a length adjustment mechanism provided on the surface of the ball, a fixing head provided at one end of the length adjustment mechanism, a tower crane attachment rod slidably sleeved on the inner wall of the fixing head, a fixing clip penetrating the inner walls of the fixing head and the tower crane attachment rod, a sliding rod slidably connected to the inner wall of the fixing head, a snap-fit ​​rod bolted to the surface of the sliding rod, and the snap-fit ​​rod slidably sleeved with the inner wall of the fixing clip, a spring provided between one end of the sliding rod and the inner wall of the fixing head, and a toggle block bolted to the surface of the sliding rod.

[0006] By adopting the above technical solution, the angle can be adjusted by loosening the fixing bolts to loosen the pressure plate and press it against the ball, then adjusting the angle to the required position, and finally tightening the fixing bolts to press the pressure plate against the ball. The length can be adjusted by rotating the threaded cylinder, which improves the installation error tolerance, has wide adaptability, and can quickly match different building facades. The sliding rod can be moved by moving the toggle block, which in turn moves the locking rod. The locking rod moves and disengages from the inner wall of the fixing clip, allowing the fixing clip to be removed and the tower crane attachment rod to be taken out. This method facilitates the installation and removal of the tower crane attachment rod, reduces workload, improves installation and removal efficiency, and is convenient to use.

[0007] The present invention is further configured such that: the length adjustment mechanism includes a threaded rod, one end of which is bolted to the surface of the ball, and a threaded cylinder is threadedly connected to the surface of the threaded rod, and one end of the threaded cylinder is rotatably connected to the surface of the fixed head.

[0008] By adopting the above technical solution and setting a length adjustment mechanism, the length of the threaded rod can be easily adjusted, thereby improving its applicability.

[0009] The present invention is further configured such that a nut sleeve is threadedly connected to the surface of the threaded rod.

[0010] By adopting the above technical solution, the threaded cylinder is fixed by setting a nut sleeve, thereby improving stability.

[0011] The present invention is further configured such that the surface of the actuating block is provided with anti-slip texture.

[0012] By adopting the above technical solution, anti-slip texture is set to prevent hand slippage and facilitate operation.

[0013] The present invention is further configured such that the surface of the threaded rod is printed with scale lines.

[0014] By adopting the above technical solution, the length can be easily adjusted by setting scale lines.

[0015] The present invention is further configured such that a hexagonal block is fixedly sleeved on the surface of the threaded cylinder.

[0016] By adopting the above technical solution, the hexagonal block is set to facilitate the rotation of the threaded cylinder and make it easy to adjust the length.

[0017] The present invention is further configured such that fixing holes are provided on the surface of the base plate.

[0018] The above technical solution facilitates installation and fixation by providing fixing holes.

[0019] In summary, this utility model has the following beneficial effects:

[0020] 1. This utility model achieves the purpose of adjusting the angle by loosening the fixing bolts to allow the pressure plate to loosen and press the rolling ball, then adjusting the angle to the required position, and then tightening the fixing bolts to press the pressure plate to press the rolling ball. The length can be adjusted by rotating the threaded cylinder, which improves the installation error tolerance, has a wide adaptability, and can quickly match different building facades.

[0021] 2. This utility model uses a movable toggle block to move the sliding rod, which in turn moves the locking rod. The movement of the sliding rod causes the locking rod to disengage from the inner wall of the fixing clip, allowing the fixing clip to be removed and the tower crane attachment rod to be taken out. This method facilitates the assembly and disassembly of the tower crane attachment rod, reduces workload, improves assembly and disassembly efficiency, and is convenient to use.
