Description

Technical Field

[0001] This utility model relates to the field of construction equipment, and in particular to a tower crane cross brace support. Background Technology

[0002] Tower cranes, also known as hoisting cranes, are a type of lifting equipment commonly used on construction sites. Hoisting machinery lifts or moves heavy objects using a hook or other lifting device. The hoisting mechanism lifts the object from its location using a lifting device, and the slewing and luffing mechanisms allow for horizontal movement of the material. The traveling mechanism enables the material to move freely within the reach of the tower crane.

[0003] Utility model patent application CN2022204850556 proposes a combined bidirectional elastic-pressure tower crane support device, which mainly consists of a support wall, crossbars, limit seats, and vibration damping springs. The vibration damping springs are sleeved on the crossbars, which are horizontally positioned, with one end fixedly connected to the tower crane and the other end passing through the support wall. As the tower crane height increases, the bidirectional elastic-pressure tower crane support device further improves the stability of the tower crane and enhances safety during hoisting. This support device provides lateral support to the tower crane body by having the crossbars pass through the wall. However, drilling through the wall reduces the structural strength of the wall and increases the workload of construction. Furthermore, the parallel and independent arrangement of the crossbars also presents the problem of insufficient support strength, which needs improvement. Utility Model Content

Each latch includes a fixed seat and an arc-shaped latch. One end of the arc-shaped latch is hinged to one end of the fixed seat, and the other end is fixed by bolts. The side braces are cylindrical rods. The outer end of the side braces is fixed in the latches. The inner end of the side braces is provided with a pad, which is an angle iron. A rubber pad is provided between the pad and the wall to increase the friction between the two. The pad is fixed to the building wall by anchor bolts. A diagonal bracing mechanism is provided between the end of one side brace and the main frame.

[0019] Example 1, see appendix Figure 1-2 A tower crane cross bracing support includes a main frame and side support rods 1 symmetrically connected to both sides of the main frame. The outer end of the main frame is connected to the tower body 41 of the tower crane. At least two locking buckles 15 are arranged side by side on the inner end side of the main frame. The side support rod 1 is a cylindrical rod, and the outer end of the side support rod 1 is fixed in the locking buckle 15. The multiple locking buckles 15 arranged side by side can securely lock the side support rod 1 to the main frame. The inner end of the side support rod 1 is provided with a pad 11, which forms an anchor support plate at the end of the side support rod 1. The pad 11 is fixed to the building wall 51 by anchor bolts 24. A diagonal bracing mechanism is provided between the end of one side support rod 1 and the main frame. The diagonal bracing mechanism supports the side support rods 1, so that the axial and radial support stability of both sides of the support rods is high.

[0020] The main frame includes a trapezoidal frame 31 and a square frame 32. The square frame 32 and the trapezoidal frame 31 are fixedly connected by a set. Locking components such as top screws are set between the sets to lock the two together. This structure helps to reduce the overall size of the frame and facilitates high-altitude assembly. The outer end of the square frame 32 is provided with an extension rod 33. The extension rod 33 is fixedly connected to the cross brace on the tower body 41 of the tower crane. The extension rod 33 and the tower body 41 of the tower crane can be fixed by welding or by locking pressure plates.

[0021] The trapezoidal frame 31 is equipped with diagonal bracing rods 34 inside, and the square frame 32 is equipped with diagonal bracing rods 34 inside. The diagonal bracing rods 34 improve the deformation resistance of the frame and enhance its support stability.

[0022] The outer end of the side support rod 1 is provided with a limiting block 14, which forms an axial limit between the side support rod 1 and the lock 15 to prevent the side support rod 1 and the lock 15 from axially slipping off in extreme cases, thus playing a safety protection role.

[0023] The inner end of the anchor bolt 24 is provided with a fastening nut 12 that supports the side of the building wall 51, and the outer end is provided with a fastening nut 12 that supports the surface of the pad 11. The two ends of the anchor bolt 24 are locked to the wall by the fastening nut 12.

[0024] In this embodiment, the tower crane cross brace is connected to the building wall 51 by bolt 24 anchoring, which reduces the damage to the wall structure. It also features a support structure with side braces 1 connected in one piece, which improves the stability of the tower crane's lateral support. At the same time, the side braces 1 adopt a telescopic and adjustable length structure, which helps to improve assembly accuracy and allows them to adapt to the cross brace assembly of various tower crane positions, enabling them to be reused.

[0025] Example 2, see appendix Figure 3-4 This embodiment is basically the same as Embodiment 1, and the similarities will not be repeated. The difference is that the diagonal bracing mechanism includes a support sleeve 2 and a telescopic rod 21. The support sleeve 2 is a square tube, and the telescopic rod 21 is a square rod. After the square rod and the square tube are sleeved together, they will not rotate relative to each other in a circle. One end of the support sleeve 2 is hinged to the end of the side support rod 1 on one side, and one end of the telescopic rod 21 is hinged to the main frame of the side support rod 1 on the other side. The hinge structure allows the telescopic rod 21 and the support sleeve 2 to be folded after disassembly, which is convenient for storage and turnover. The tube can also be finely adjusted in position by its own rotation to ensure the smoothness of the relative sliding of the diagonal bracing mechanism. The telescopic rod 21 is slidably fitted inside the support sleeve 2. A locking component is provided between the telescopic rod 21 and the support sleeve 2. The diagonal bracing mechanism can be lengthened or shortened by the relative sliding of the telescopic rod 21 and the support sleeve 2, so that it can be strongly supported between the diagonal support rods 34, thereby improving the cross bracing strength between the diagonal support rods 34 and the wall.

[0026] The locking assembly includes several external insertion holes 22 evenly arranged on the support sleeve 2 and several internal insertion holes 23 evenly arranged on the telescopic rod 21. Bolts 24 are installed between the corresponding internal insertion holes 23 and external insertion holes 22. The telescopic rod 21 and the support sleeve 2 are locked by installing bolts 24 between the internal and external insertion holes 22, which has the advantages of convenient operation and good locking effect.
