[0021] like Figure 1 - Figure 3 As shown, the utility model provides a technical solution: the cross brace connection device between the cable towers of the gantry truss structure cable crane is mainly used to improve the stability and safety of the cable crane.

[0022] The device mainly includes at least two groups of connecting parts 2, each group of connecting parts 2 is provided with two connecting parts, and these connecting parts 2 are respectively installed on two main chord tubes 3 to make the whole structure more stable. The connecting parts 2 are connected by the belly tube 1 to form a trapezoidal cross brace connecting device. This design makes the connection between the cable towers more firm and helps to improve the stability of the entire cable crane suspension.

[0023] like Figure 2 As shown, in order to ensure the smooth implementation of this embodiment, it is necessary to know that the connecting member 2 includes two arc-shaped plates 201, which are connected to each other by connecting bolts 204 and fit tightly on the main chord tube 3. This design helps to better disperse the load, reduce the stress on a single part, and improve the durability of the overall structure. A base plate 202 is fixed to the bottom of the arc-shaped plate 201, and a groove is opened in the middle of the base plate 202. A frame rod 203 is rotated at the groove of one of the base plates 202, and protrusions 205 are fixed on both sides of the groove of the other base plate 202. The protrusions 205 are connected by screws 206. This design makes the connection more firm and helps to improve the reliability of the device. The belly tube 1 is mainly composed of a steel tube body 101, and bayonet sockets 102 are opened at both ends of the steel tube body 101.

[0024] like Figure 3 As shown, what needs to be known about this scheme is that the bayonet 102 is adapted to the rack 203, and when the belly tube 1 is in a vertical state, the bayonet 102 at both ends of the steel tube body 101 are respectively inclined in the first direction and the second direction from the axis of the steel tube body 101. During use of the device, one end of the belly tube 1 is placed between the two bottom plates 202 of one of the main chord tubes 3, and after the rack 203 is rotated to clamp the rack 203 in the bayonet 102, the other end of the belly tube 1 is then operated in the same manner to connect the belly tube 1 to the two main chord tubes 3.

[0025] A single connecting cross brace is composed of a chord tube 3 and a belly tube 1. The chord tube 3 is a 351×10×5810mm steel tube, and the belly tube 8 is a 300×6mm steel tube. First, the fixed cross brace is processed and fixed on the ground according to the drawings, and then a tower crane is used to lift the fixed cross brace as a whole including the main chord tube 3 to the back beam for installation and fixation;

[0026] After the fixed cross braces and chord tube 3 are installed, the surveying personnel will accurately measure the connecting cross braces between the fixed cross braces, and the on-site construction personnel will cut and process the connecting cross braces and chord tube 3 according to the measurement data. After the overall processing of the connecting cross braces and chord tube 3 is completed, the connecting cross brace will be hoisted as a whole by a tower crane. After the Bailey beam welding is completed at high altitude, the cross brace connection can be dismantled to complete material recycling and improve resource reuse rate.
