Description

Technical Field

[0001] The present application relates to the technical field of tower cranes, and in particular to a lateral connection structure of a tower crane. Background Art

[0002] Tower crane is a kind of lifting equipment commonly used on construction sites. It is used to transport materials on construction sites, which greatly facilitates the construction process.

[0003] Prefabricated assembled buildings are mainly made of prefabricated concrete floor slabs. When the building floors are higher, the height of the tower crane will also increase accordingly. In order to increase the stability of the tower crane, lateral connecting rods are usually added to the tower crane to connect with the prefabricated floor slabs in the building. However, since the installation position of the tower crane at the construction site is not fixed, the distance between the lateral connecting rods and the prefabricated floor slabs in the building is different. Each lateral connecting rod needs to be measured on site and customized. This increases the complexity of the construction operation and is inconvenient to use. Utility Model Content

In order to facilitate installation, a positioning block 10 for positioning the first crossbeam 11 is also formed on the corner frame, and the positioning block 10 has a positioning groove for positioning the tower crane. When in use, the corner frame is first positioned on the tower crane through the positioning block 10 and connected, and then the connecting beam is placed in the two corner frames and connected, thereby completing the connection of the first crossbeam 11, and then the second crossbeam 12 is installed between the first crossbeams 11 on both sides and connected, thereby completing the connection of the second crossbeam 12 and realizing the installation of the connecting frame 1 on the tower crane.

[0033] like Figure 1 , Figure 2 , Figure 3 As shown, a connecting arm 2 is rotatably connected to the corner frame of the first crossbeam 11, and a plurality of connecting arms 2 are provided. In the present embodiment, four connecting arms 2 are provided, and one connecting arm 2 is rotatably connected to one corner frame, so that the four corner frames are all connected with connecting arms 2. The connecting arms 2 are used in pairs when in use. The tower crane is usually installed in the middle of a building. The two connecting arms 2 facing the left side of the building are used as a group, and the two connecting arms 2 facing the right side of the building are used as a group, which can effectively increase the connection strength between the tower crane and the building. A telescopic arm 3 is slidably connected to the connecting arm 2, and a slide rail 5 cooperating with the telescopic arm 3 is formed inside the connecting arm 2 to facilitate the sliding of the telescopic arm 3 in the connecting arm 2. A driving member for driving the telescopic arm 3 to move is installed inside the connecting arm 2, and the driving member is a hydraulic cylinder 4 installed inside the connecting arm 2.
