Description

Technical Field

[0001] This utility model relates to the field of tower crane technology, specifically to a tower crane attachment device. Background Technology

[0002] Tower cranes, also known as tower hoists, are mainly used for the vertical and horizontal transport of materials and the installation of building components in construction. When the working height of a tower crane exceeds its independent working height, it needs to be equipped with anchoring devices to increase its stability.

[0003] According to a published application for a flexible attachment device for tower cranes (Announcement No.: CN221988030U), the four attachment rods on the same horizontal plane in the above application make the reinforcement of the tower crane support more effective and avoid the instability of the tower crane when it is too high.

[0004] However, in actual use, the above-mentioned equipment cannot guarantee that the attachment rods are on the same horizontal line. When the tower crane is fixed by the attachment device, the inconsistent positions of the attachment rods cause the tower crane to be fixed in an inconsistent position. As a result, when the tower crane is blown by a fast wind, the force direction of the attachment rods is inconsistent. Therefore, the fixing effect of the attachment rods is reduced. We propose a tower crane attachment device. Utility Model Content

[0010] Preferably, the end of the spring away from the limiting block is fixedly connected to the inner wall of the slide groove, the size of the limiting groove matches the size of the limiting block, and the limiting block engages with the limiting groove. When the limiting block engages with the limiting groove, the locking rod can be fixed inside the reinforcing plate, so that the support plate can be fixed after the hook plate moves, and the support plate can be tightly fitted with the reinforcing plate.

[0011] Preferably, one end of the torsion spring is fixedly connected to the outer wall of the rotating seat, and the other end of the torsion spring is fixedly connected to the outer wall of the hook plate. The length of the lower end of the hook plate is consistent with half the width of the support plate, so that the two sets of hook plates can fully clamp the support plate, and the support plate can be clamped by the hook plate and the reinforcing plate.

[0012] Preferably, the attachment frame is L-shaped, and there are two sets of attachment frames. The two ends of the two sets of attachment frames are respectively attached together, and the two sets of connecting plates are connected by connecting bolts.

[0013] Preferably, the number of support plates is set to four sets, and the four sets of support plates are mirror-distributed on the outer walls of the two sets of attachment frames. The two sets of support plates located on the same set of attachment frames are considered as a pair, and the pair of support plates consists of one long and one short plate, so that the support plates can fix more positions on the outer walls of the attachment frames.

[0014] Preferably, the upper outer wall of the locking rod contacts the push plate, the movable plate passes through the reinforcing plate, and the movable plate is slidably connected to the inner wall of the reinforcing plate. When the locking rod is inserted into the locking groove, the locking rod pushes the push plate to move, so that the push plate moves the hook plate through the movable plate, thereby allowing the hook plate and the reinforcing plate to clamp the support plate, thus fixing the position of the support plate.

[0015] Compared with the prior art, the present invention provides a tower crane attachment device, which has the following advantages:
