Description

Technical Field

[0001] This utility model relates to the technical field of fixing devices, specifically to a fixing device for a cable guide frame of a gantry crane. Background Technology

[0002] Gantry cranes are widely used in dockside loading and unloading operations, easily handling various cargoes, including bulk commodities such as iron ore, grain, coal, bauxite, cement, timber, and steel plates, as well as diverse goods such as ship outfitting, bagged solid chemicals, general cargo, and containers. Their flexible loading and unloading capabilities make them versatile tools in dockside operations. Gantry cranes mostly operate along crane rails on the ground or buildings for lifting and unloading operations.

[0003] The cables used in gantry cranes need to be brought in from the ground, redirected by a cable guide device installed on the ground, and finally connected to the gantry crane. Gantry cranes used in ports are usually very close to the sea, and during high tides and strong winds, swells can wash ashore. The cable guide device on the ground is subjected to repeated impacts from these swells over a long period, and the cables in the cable trench are also under stress. This results in stress on the cable guide device from multiple directions, including the cables and the swells. Under this stress, gaps can form between the cable guide device and the cable trench. If these gaps become too large, the force of the swells can cause the cable guide device to detach from the trench, pulling the cable out and causing impacts and repeated friction against the gantry frame, thus damaging the cable and causing equipment downtime.

[0004] Therefore, in order to avoid this situation, it is extremely important to protect the cable guide frame from the impact of surge waves. Utility Model Content

[0005] To address the problem that cable guide frames of gantry cranes are prone to detaching from their original fixed positions due to impact, this utility model provides a fixing device for cable guide frames of gantry cranes to solve the above-mentioned problem.

[0006] The technical solution of this utility model is as follows:

[0007] A fixing device for a cable guide frame of a gantry crane includes a base; an upper crossbeam is provided on the top of the base; the upper crossbeam is provided with a first fixing part for vertically fixing the cable guide frame; the first fixing part includes a fixing block fixedly connected to the upper crossbeam; the fixing block is provided with a threaded hole; a threaded rod is threadedly connected to the threaded hole; a connecting ring is provided at the top of the threaded rod; a handle is movably connected inside the connecting ring; and a fixing plate is connected to the bottom of the threaded rod.

[0008] Furthermore, each of the four feet of the base is equipped with a fixing rod. The fixing rods are located on the ground and are secured with latches fixed to the ground, thereby fixing the fixing device to the ground.

[0009] Furthermore, the handle is U-shaped, and when the two sides of the handle face downwards, the vertical part is located on both sides of the base, which can limit the rotation of the handle.

[0010] Furthermore, a reinforcing rib is provided at the connection between the base and the fixing rod to enhance the stability between the fixing rod and the base.

[0011] Furthermore, the four fixing rods are arranged in the same direction, the same as the placement direction of the cable guide frame.

[0012] Furthermore, the base has side beams on two opposite sides; each side beam has a second fixing part for horizontally fixing the cable guide frame. This added horizontal fixing makes the cable guide frame more stable.

[0013] Furthermore, the second fixing part includes a threaded ring connected to the side crossbeam; the threaded ring is threadedly connected to a fastening bolt.

[0014] Furthermore, the side crossbeam and the fixing rod are arranged in the same direction.

[0015] The beneficial effects of this utility model are as follows:

[0016] This invention provides a fixing device for a cable guide frame of a gantry crane, solving the problem that the cable guide frame of a gantry crane is prone to detaching from its original fixed position under impact. This invention restricts the displacement of the cable guide frame through a frame-type base, and further stabilizes it vertically through a first fixing part, making the cable guide frame more stable and able to withstand the impact of surge waves.
