DETAILED DESCRIPTION

[0020] The utility model is further described below in conjunction with the accompanying drawings.

[0021] A gantry crane comprises a gantry 1, a lifting mechanism 2 and a line support 3, wherein the lifting mechanism 2 is slidably mounted on the gantry 1, a transverse driving member 5 is mounted on the gantry 1, the transverse driving member 5 is connected to the lifting mechanism 2, and drives the lifting mechanism 2 to translate on the gantry 1, a line support 3 is mounted on the lifting mechanism 2, and drag chains 4 are connected at both ends of the line support 3, so that the two ends of the line support 3 are respectively connected to the gantry 1 and the lifting mechanism 2, and the line used to control the lifting mechanism 2 is bound by the line support 3, so as to protect the line of the gantry crane.

[0022] The gantry 1 includes a crossbeam 1-2 and a support frame 1-3. The crossbeam 1-2 is fixed between adjacent support frames 1-3. The lifting mechanism 2 and the transverse driving member 5 are respectively installed on the crossbeam 1-2. Limit baffles 1-1 are respectively installed at both ends of the crossbeam 1-2. The limit baffles 1-1 are adapted to the lifting mechanism 2 to limit the lateral movement of the lifting mechanism 2. Preferably, the limit baffle 1-1 is arranged opposite to the sliding bottom plate 2-1 of the lifting mechanism 2. When the sliding bottom plate 2-1 moves to the position of the limit baffle 1-1, the lifting mechanism 2 stops, so that it can no longer move laterally outward.

[0023] The lifting mechanism 2 includes a sliding base plate 2-1, a lifting arm 2-2 and a mounting plate 2-3. The sliding base plate 2-1 is slidably mounted on the gantry 1 through a slide rail to facilitate the transverse movement of the lifting mechanism 2. Two mounting plates 2-3 are fixedly mounted on the sliding base plate 2-1, and the lifting arm 2-2 is slidably mounted between adjacent mounting plates 2-3, that is, the lifting arm 2-2 is liftably mounted on the sliding base plate 2-1 through the mounting plate 2-3.

[0024] A guide is provided on the mounting plate 2-3, and the lifting arm 2-2 is mounted on the mounting plate 2-3 through the guide. The guide includes a slider 2-9 and a guide rail 2-10 that are slidably connected to each other. The guide rail 2-10 is fixed on the lifting arm 2-2, and the slider 2-9 is fixedly connected to the mounting plate 2-3. In order to ensure the smoothness of sliding, the guide on the market will have a certain gap between the slider 2-9 and the guide rail 2-10, that is, the slider 2-9 can shake relative to the guide rail 2-10. The lower the precision of the guide, the greater the shaking amplitude. This embodiment eliminates the influence of the gap between the slider 2-9 and the guide rail 2-10 on the lifting stability of the lifting arm 2-2 by controlling the spacing between the mounting plates 2-3, thereby improving the lifting stability of the lifting arm 2-2.

[0025] The motor mounting frame 2-7 is installed on the sliding bottom plate 2-1, and the motor mounting frame 2-7 is provided with an adjustment through hole 2-8, which is arranged toward the mounting plate 2-3, and has an internal thread in the adjustment through hole 2-8. A screw is detachably installed in the adjustment through hole 2-8, and the position of the mounting plate 2-3 on one side is adjusted by turning the screw, so as to facilitate the adjustment of the spacing between adjacent mounting plates 2-3, thereby eliminating the influence of the gap between the slider 2-9 and the guide rail 2-10 on the lifting stability of the lifting arm 2-2. Preferably, after the mounting plate 2-3 is installed, the screw in the adjustment through hole 2-8 is removed.

[0026] The lifting mechanism 2 also includes a lifting drive component, which includes a lifting motor 2-4, a lifting gear 2-5 installed on the lifting motor 2-4, and a lifting rack 2-6 meshing with the lifting gear 2-5. The lifting motor 2-4 is installed on the sliding base plate 2-1, and the lifting rack 2-6 is installed on the lifting arm 2-2 for lifting the lifting arm 2-2.

[0027] The line support 3 includes a transverse tube 3-3, a vertical tube 3-4 and a connecting plate 3-5 for connecting the transverse tube 3-3 and the vertical tube 3-4. The connection between the transverse tube 3-3 and the vertical tube 3-4 forms a corner 3-1, and the opening direction of the line support 3 is changed by the corner 3-1. A corner end cover 3-2 is detachably installed on the corner 3-1 to facilitate threading in the line support 3.

[0028] The transverse driving member 5 includes a transverse motor 5-1, a transverse screw rod 5-2 and a slider 5-3. The transverse motor 5-1 is fixed at the bottom of the beam 1-2, the transverse screw rod 5-2 is connected to the transverse motor 5-1, the slider 5-3 is installed on the transverse screw rod 5-2 through threads, and the sliding base plate 2-1 is connected to the slider 5-3.
